VENDOR COMPLIANCE TO STATE LAW The 1985 Session of the Texas Legislature passed House Bill 620 relative to the award of contracts to non-resident bidders. This law provides that, in order to be awarded a contract as low bidder, non-resident- bidders ( out of state contractors whose corporate offices or principal place of business are outside of the State or Texas) bid projects for construction, improvements, supplies or services in Texas at an amount lower than the lowest Texas resident bidder by the same amount that a Texas resident bidder would be required too underbid a non-resident bidder in order to obtain a comparable ~ontract in the State in which the non-resident 's principal place of business is located. The appropriat(j" blanks in Section A must be filled out by all out-of-state or non-resident bidders in order for your bid to meet specifications . The failure of out-of-state or non-resident contractors to do so will automatically disqualify that bidder. Resident bidders must check the box in Section B. · A. Non-Resident vendors in _______ (give State), our principal place of business, are required to be percent lower than resident bidders by State law. A copy of the Statute is attached.

SUMMARY OF THE WORK 1.1.1. CONTRACT DOCUMENTS AND RELATED REQUIREMENTS: General provisions of the contract , including general and supplementary cond itions , apply to the work of this sect ion. The contract documents show the work of the contract and related re- quirements and conditions impacting the project. Related requirements and conditions include appl icable codes and regulations , notices and permits , existing site conditions and restr ictions on use of the site , requirements for partial owner occupancy during work , coordination with other work and phasing of work. Whenever there is a conflict or overlap of the above refer- ences , the more stringent provisions apply. 1.1.2. EXTENT OF WORK: A brief summary of the extent of the work and non-binding to the contract documents is as fol- lows: BASE BID: Removal and disposal of asbestos-containing materials (ACM) and asbestos-contam inated elements (ACE) utilizing wet methods within full , negative-pressure conta inments equ ipped with HEPA ventilation from specified areas of the buildings . The following asbestos-containing ma- terials (ACM) will be removed at the property where applicable . 3200 Lackland, Fort Worth, Texas Floor tile and mastic 3,172 square feet South room, kitchen and storage room The Work Area will be inclus ive of the locations and the quantities noted above , in the attached drawings , and as directed by a representative of IHST . The Work may be broken down into multiple Work Areas at the discretion of the Contractor. However, the Contractor will receive no additional time to perform the work on the basis of having multiple Work Areas and associated Cleaning Sequences . The Contractor will be responsible for the removal and disposal of the asbestos-containing ma- terial and asbestos-contaminated materials in accordance with Texas Department of State Health Services (TDSHS), OSHA 29 CFR 1926 .1101 , Asbestos Hazard Emergency Response Act (AHERA) 40 CFR Part 763 , and the National Emission Standards for Hazardous Air Pollut- ants (NESHAP) Regulations 40 CFR Part 61 . )/~'< B,;,-/.;tr' DSHS License 10-5040 Expires 12-31-0911 Page 1 ASBESTOS REMOVAL The CONTRACTOR shall be responsible for verifying existing site conditions and determining the quantity of ACM delineated for removal prior to abatement described in these specifications and associated drawings. 1.1.3. TASKS: The work, located at the facility , is summarized briefly as follows : The PROJECT requires the removal of the materials outlined in Section 1.1.2. The asbestos abatement will be performed in accordance with these specifications and procedures as out- lined . Power and Water Connections: The City will supply water and power for this project. Asbestos Removal within full Containment: The Contractor will use wet methods for all re- moval operations. The Contractor is responsible for prompt clean-up and disposal of waste and debris contaminated with asbestos in leak tight containers. The Contractor will conduct a wet decontamination of equipment and tools before final clearance sampling in the work area. The Contractor will use the existing interior walls and will have to build a false ceiling above the plaster lathe which will be removed to provide structural support for an asbestos containment work area provided the containment remains sound and is not in danger of collapse. The Con- tractor should make every effort not to damage the interior walls of the building during the pro- ject. The Contractor will establish critical barriers over all openings into the work area . ACM debris should be adequately wetted prior to establishing perimeter critical barriers The full containment design must be structurally sound so that it will not collapse under negative pressure and work conditions. A structurally unsound containment design will not be ac- cepted. The full containment design will consist of one (1) layer of 6-mil polyethylene sheeting for all critical barriers, floors and walls. Two layers of polyethylene sheeting will be required on walls and floors not affected by the abatement Polyethylene sheeting shall meet the requirements in accordance with current TDSHS rules. The Contractor must establish negative air into the containment and maintain a pressure differential of -0.02 inches of water as indicated by a working manometer. After the ACM has been removed and the work area cleaned , a detailed visual clearance in- spection will be conducted to determine if ACM or asbestos-contaminated elements (ACE) re- main prior to final clearance and work completion. OSHA personnel and area monitoring will be conducted with analysis by (PCM). Final air clearance sampling will be conducted utilizing PCM. Before the containment can be removed, the area must be cleared per the mold protocol. Respiratory protection will require half-face, air-purifying respirators (APR) with NIOSH- approved P-100 (HEPA) cartridges during removal. )/~I( ~(.;Jr" DSHS License 10-5040 Expires 12-31-11 Page 2 ASBESTOS REMOVAL The CONTRACTOR is responsible to verify site conditions and estimated quantities of ACM to be removed. 1.1.4. CONTRACTORS USE OF PREMISES: Cooperate fully with the Owner's Representative to minimize conflicts and to facilitate Owner's safe and smooth usage of buildings . Perform the work in accordance with specifications , draw- ings , and phasing plan . Use existing facilities in building strictly within the limits shown in contract documents and the approved pre-abatement plan of action. Several of the structures have asbestos containing ma- terials in the flashing around roof penetrations. The Contractor will not be required to remove the flashing on the structures . 1.2. DIFFERING SITE CONDITIONS: The quantities and location of ACM indicated on the drawings and the extent of work included in this section are only best estimates which can be limited by the physical constraints imposed by structural enclosures or by occupancy of the building. The CONTRACTOR is responsible to verify site conditions and estimated quantities of ACM to be removed and determining the quantity of ACM delineated for removal prior to abatement described in these specifi- cations and associated drawings. The Contractor by placing a bid for this project agrees with all quantity estimates and there bid reflects there price to remove all of the material at all of the structures as identified in these specifications. 1.3. STOP ASBESTOS REMOVAL: If the Owner's Representative presents a written Stop Asbestos Removal Order , immediately stop all asbestos remova l and initiate fiber reduction activities. Do not resume asbestos removal until authorized in writing by Owner's Representative . A Stop Asbestos Removal Order will be issued at any time the Owner or Owner's Representative determines abatement conditions are not within specifications requirements . Stoppage will continue until conditions have been corrected. Standby time and cost required for corrective action is at Contractor's expense . The occurrence of the following events will be re- ported in writing to the Owner's Representative and will require the Contractor to automatically stop asbestos removal and initiate fiber reduction activities: A. Excessive airborne fibers outside containment area (0 .01 flee or greater). B. Break in conta inment barriers. C. Loss of negative air pressure (at or above 0.01 inches of water) D . Serious injury within the containment area. E. Fire and safety emergency F . Respiratory system failure. G . Power failure. H.

PAPR must be used for friable surfac- ing or thermal system insulation removal until fiber counts are confirmed consis- tently below the PEL and STEL. Head coverings : PAPR respirators will be equipped with full facepieces. Full facepieces will be worn with either a bonnet-type disposable head cover/hood or with a full head cover/hood which is part of a fully encapsulating protective garment. Respirator straps will be located under the hoods . This allows removal of the head covering prior to showering without disturbing the respi- rator (which is worn into the shower). Exemptions from maximum respiratory protection during abatement operations : When the abatement contractor has demonstrated to the Owner's satisfaction that levels of airborne as- bestos fibers in the work area are consistently below 0 .1 flee , a full facepiece or half face respi- rator with HEPA cartridges may be used . The Certified Industrial Hygienist will determine if a lesser form of respiratory protection may be used . 1.7. WORKER PROTECTION: 1.7.1. TRAINING PRIOR TO ENGAGING IN ABATEMENT WORK: Train workers in accordance with OSHA 29 CFR 1926 .1101 and the Texas Asbestos Health Protection Rules and this section . Workers will be trained and be knowledgeable on the follow- ing topics : Methods of recognizing ACM ; health effects of asbestos exposure ; effects of smok- ing and asbestos exposure ; activities that could result in hazardous exposures; protective con- trols , practices and procedures to minimize exposure including engineering controls, work prac- tices , respirators , housekeeping procedures , hygiene facilities , protective clothing , decontamina- tion procedures , emergency procedures and waste transportation and disposal ; review OSHA 29 CFR 1910.134 for respirators; medical surveillance program ; review OSHA 29 CFR 1926.1101 , and for air monitoring , personnel and area ; review this section of the project specifi- cations . 1.7.2.

Provide adequately sized OF to accommodate the number of employees scheduled for the project. The center chamber of the three chamber OF will be fitted with as many portable walk through shower stalls as necessary so that all employees will be able to go through the en- tire decontamination procedure within 15 minutes. Construct OF of opaque or colored polyethyl- ene for privacy. Construct OF so that it will not allow for parallel routes of exit without shower- ing. 1.9. NEGATIVE PRESSURE FILTRATION SYSTEMS: The Asbestos Abatement Contractor will provide enough HEPA-filtered negative air units to completely exchange the work air four (4) times per hour. Contractor will demonstrate the num- ber of units needed per work area for 4 room air changes by calculating the volume flow rate (cfm) delivered by each unit under 2" pressure drop across filters . Provide at least one standby unit in the event of a machine failure or emergency such as contamination in surrounding non- work area . When a pressure differential system is selected provide enough HEPA filtration units to filter and recirculate the air in the work area at a rate of four (4) room air changes per hour. 1.9.2. PRESSURE DIFFERENTIAL: Provide a fully operational negative air system within the work area continuously maintaining a pressure differential across work area enclosures of -0.02 inches of water. Demonstrate to the Owner's Representative the pressure differential by use of a pressure differential meter or a manometer, before disturbance of any asbestos containing materials . This pressure differential will be used for either negative air system or pressure differential system . 1.9.3. MONITORING: Continuously monitor and record the pressure differential between the work area and the build- ing outside of the work area with a monitoring device incorporating a strip chart recorder. Make the strip chart record part of the project log . Page 9 ASBESTOS REMOVAL 1.9.4. TESTING THE SYSTEM: Test negative-pressure system before any ACM is wetted or removed. After the work area has been prepared , the decontamination facility set up, and the exhaust unit(s) installed , start the unit(s) (one at a time). Demonstrate operation and testing of negative-pressure system to the Owner's Representative . 1.9.5. DEMONSTRATION OF NEGATIVE AIR SYSTEM OPERATION: Demonstrate the operation of the negative-pressure system to the Owner's Representative to include , but not be limited to , the following : 1. Demonstrate pressure differential system will maintain -0.02" of water. 2 . Emergency shutoff will operate in case of fire . 1.9.6. USE OF SYSTEM DURING ABATEMENT OPERATIONS: Start exhaust units before beginning work (before any ACM is disturbed). After abatement work has begun, run units continuously to maintain a constant negative-pressure until decontamina- tion of the work area is complete. Do not turn off units at the end of the work shift or when abatement operations temporarily stop. Do not shut down negative air system during abatement operations procedures , unless author- ized by the Owner's Representative in writing . The systems may be shut down daily if air moni- toring in the containment shows airborne levels of less than 0.01 fibers/cc. Start abatement work at a location farthest from the exhaust units and proceed toward them. If an electric power failure occurs , immediately stop all removal work and do not resume until power is restored and all exhaust units are operating again . At completion of abatement work , allow exhaust units to run as specified under this section, to remove airborne fibers that may have been generated during abatement work and cleanup and to purge the work area with clean makeup air. Units may be required to run after decontamina- tion , if dry or only partially wetted asbestos material was encountered during any abatement work . 1.9.7. DISMANTLING THE SYSTEM: When a final inspection and the results of the final air tests indicate that the area has been de- contaminated, exhaust units may be removed from the work area . Before removal from the work area , remove and properly dispose of pre-filters, and seal intake to the machine with 6-mil polyethylene to prevent environmental contamination from the pre-filters. 1.10. CONTAINMENT BARRIERS AND COVERINGS OF WORK AREA: 1.10.1. GENERAL: Seal off perimeter of work area to completely isolate abatement areas and to contain all air- borne asbestos contamination created by abatement work. Cover all surfaces of the work area to protect them from cross contamination , to facilitate more efficient cleanup , and to protect the finishes from the asbestos abatement work. Should the area beyond the seal off limits become Page 10 ASBESTOS REMOVAL contaminated as a consequence of the work, clean those areas in accordance with procedures described in this section at no additional cost. 1.10.2. PREPARATION PRIOR TO SEALING OFF: Place all tools, staging, etc. necessary for the work in the area to be isolated prior to erection of temporary plastic sheeting enclosure. Disable ventilating systems or any other system bringing air into or out of the work area . Disable system utilizing positive means that will prevent acci- dental premature restarting of equipment, i.e., disconnecting wires, removing circuit breakers , lockable switch , etc. 1.10.3. CONTROL ACCESS TO WORK AREA: Permit access to the work area only through the OF. All other means of access will be closed off and sealed and warning signs displayed on the clean side of the sealed access . Where the work area is immediately adjacent to or within view of occupied areas , provide a visual barrier of opaque polyethylene sheeting at least 6-mil .in thickness so that the work procedures are not visible to building occupants. Where the area adjacent to the work area is accessible to the public, construct a barrier of plywood or other suitable material at least eight feet (8') in height that is able to withstand the negative pressure as specified . Post warning signs at each visual and physical barrier per OSHA requirements . Alternate method of containing the work area or different definition of the limits of seal-off from the one shown on the drawings may be submitted to the Owner's Representative for approval in accor- dance with this section . Do not proceed with any such alternatives without prior written approval by the Owner's . · 1.10.4. CRITICAL BARRIERS: Completely separate the work area from other portions of the building, and the outside by sheet polyethylene barriers at least 6 mil in thickness and sealing with duct tape. Individually seal all ventilation openings (supply and exhaust), lighting fixtures , doorways, windows , and other open- ings into the work area with duct tape alone and with polyethylene sheeting at least 6-mil in thickness , taped securely in place with duct tape . Maintain seal until all work including project decontamination is completed . Take care in sealing off lighting fixtures to avoid melting or burn- ing of sheeting. Provide sheet plastic barriers at least 6-mil in thickness as required to com- pletely seal openings from the work area into adjacent areas. Seal the perimeter of all sheet plastic barriers with duct tape or spray cement. 1.10.5. PRIMARY BARRIERS: The primary barrier of the full containment walls will consist of a minimum of Primary barriers for full containment shall consist of two (2) layers of minimum 4-mil polyethylene sheeting for the walls securely anchored from the floors to the ceiling. The containment for the removal of the li- noleum flooring will require a minimum 4-mil polyethylene sheeting for the ceiling. Polyethylene sheeting shall meet ASTM requirements in accordance with TDSHS regulations . Visible open- ings observed along the perimeter walls and the ceiling shall be completely sealed polyethylene sheeting and the wall corners of the containment should be attached with an overlap of at least twelve inches . The primary barrier construction should form an airtight , impermeable , perma- nent barrier around the ACM and ACM debris to contain the release of asbestos fibers into the air. Page 11 ASBESTOS REMOVAL 1.10.6. EXTENSION OF WORK AREA: If the enclosure barrier is breached in any manner that could allow the passage of asbestos de- bris or airborne fibers, then where possible , add affected area to the work area. Enclose it as required by this Section of the specification and decontaminate it as described elsewhere in this section . If contaminated area cannot be added to work area , decontamination measures will start immediately after contamination is discovered and work will stop in work area. Decontami- nation procedures will continue until exposure returns to background levels. 1.10.7. SECONDARY BARRIERS: Secondary barriers should be established in areas to separate any non -related work activity from the abatement containment to prevent dust or debris from potentially contaminating fresh air (make-up air) into the containment or regulated asbestos removal area . 1.11. MONITORING, INSPECTION AND TESTING: 1.11.1. GENERAL: Perform throughout abatement work monitoring , inspection and testing inside the work area in accordance with OSHA requirements and these specifications. I.H. Technician will continuously inspect and monitor conditions inside the work area to ensure compliance with these specifica- tions. In addition , the I.H . will personally manage air sample collection, analysis and evaluation for personnel and work area samples to satisfy OSHA requirements. Additional inspection and testing requirements are specified in other parts of this section. The Owner will employ a Certified Industrial Hygienist (C .1.H.) representative to perform various services on behalf of the Owner. The C.I.H. representative or representative under the direction of a C.I.H . will perform the necessary monitoring , inspection, testing and other support services to ensure that the Owner, employees and visitors will not be adversely impacted by the abate- ment worked , and that the abatement work proceeds in accordance with these specifications , that the abated areas or abated buildings have been successfully decontaminated. The work of the C.I.H. representative in no way relieves the abatement Contractor from his responsibility to perform his work in accordance with contract documents , to perform continuous inspection , monitoring and testing for the safety of his employees , and to perform other such services as specified in this section . The cost of the CIH representative and his services will be born by the Owner except for repeated final inspection and testing that may be required due to unsatisfac- tory initial results . These repeated final inspections and testing, if required , will be paid for by the Contractor. The Asbestos Abatement Contractor may request confirmation of above results . This request must be in writ ing and submitted to the Owner's Representative. Cost for the confirmation of re- sults will be born by the Contractor for both the collection and analysis of samples and for the time delay that may result for this confirmation. Confirmation sampling and analysis will be the responsibility of the Contractor with review and approval by the C.I.H . Page 12 ASBESTOS REMOVAL 1.11.2. OUTLINE SCOPE OF SERVICES OF THE OWNER'S CONSULTANT: The purpose of the work of the Owner's Representative is to: assure quality , resolve problems , and prevent the spread of contamination beyond the work area . In addition, the consultants work include performance of final inspection and testing to determ ine whether a space or a building has been adequately decontaminated. All air monitoring is to be done utilizing PCM sampling procedures with final clearance to be perfo rmed by TEM. The Owner's Representa- tive will perform the following tasks : TASK 1: Establish background levels before abatement work will start. This will in- clude taking background samples (at least 3) and retaining samples for pos- sible TEM analysis . TASK 2: Perform continuous air monitoring , inspection and testing outside the work area during actual abatement work area . In addition , the Owner's Represen - tative will be required to detect any faults in the work area isolation and any adverse impact of surroundings from work area activities .

TASK 6 : Issue certificate of decontamination for each area or building and a final project report. TASK 7: The Owner's Representative will have authority to require building materials to be removed and disposed of as ACM waste where visible ACM debris is pre- sent. All data , inspection results and testing results generated by the Owner's Representative will be available to the Contractor for information and consideration. Contractor will provide coopera- tion and support to the Owner's Representative for efficient and smooth performance of their work. Monitoring and inspection results of the Owner's Representative will be used by the Owner to issue any Stop Asbestos Removal Orders to the contractor during abatement work and to ac- cept or reject an area or a building as decontaminated. The Owner's Representative will make available to the Contractor the plan for sample collection and analysis for continuous mon itoring outside the work areas and the plan of final inspection and testing for each space or building prior to executing each plan. Plan will include location for samples , name and qualification of person taking samples , whether on site analysis and/or lab analysis will be utilized , methodol- ogy of analysis , lab information and qualifications of on-site analyst. 1.11.3. MONITORING, INSPECTION AND TESTING BY ABATEMENT CONTRACTOR: The Contractor is responsible for managing all monitoring , inspection and testing required by these specifications and the OSHA requirements . Page 13 ASBESTOS REMOVAL The analytical laboratory that will be used by the Contractor to analyze the samples w ill be AIHA P.A.T . Accredited and Texas Department of State Health Services Licensed. Keep a daily log of personnel samples taken and analyzed and make log available to the Owner's Representa- tive . Log will contain information on the persons sampled , the date of sample collection the time of sample start and finish , flow rate , sample volume and fibers/cc . Take and analyze personnel samples for at least 25% of the workers in each shift , but not less than two where active abate- ment takes place . 1.11.4. ANALYSIS: Bulk samples (if required) will be analyzed at a laboratory that is Accredited by the National Vol- untary Laboratory Accreditation Program (NVLAP). Proof of accreditation must be submitted prior to the project start date . Polarized light microscopy will be used to analyze bulk samples . Air samples will be analyzed by an individual participating in the American Industrial Hygiene Association's (AIHA) Proficiency Analytical Testing Program . In addition to the continuous monitoring required , the Owner's Representative will perform in- spection and testing at the final stages of abatement for each work area or building as specified elsewhere in this section. 1.12.5. SUBMITTALS AT COMPLETION OF ABATEMENT: The Contractor will submit a final project report consisting of the daily log book and the docu- mentation of events during abatement including the original disposal manifests signed by the operator of licensed landfill. The project report will include a certificate of completion , dated and signed by the Contractor . All certificates and original disposal manifests are due to the Owner's Representative office within 30 (thirty) days after completion of abatement work. PART 2 -EXECUTION 2.1. PREABATEMENT ACTIVITIES: 2.1.1. PREABA TEMENT MEETING: The Owner's Representative , upon receipt , review and substantial approval of all preabatement submittals and upon verification that all material and equipment required for the project are on site , will arrange for a preabatement meeting between the Asbestos Abatement Contractor , su- perintendent and foremen and the Owner's Representatives . The purpose of the meeting is discuss any aspects of the submittals needing clarification or amplification and to discuss any aspects of the project execution and the sequence of operations. The Asbestos Abatement Contractor and his employees will be prepared to provide any sup- plemental evidence and information to the Owner's Representative pertaining to any aspects of the submittals or the materials and equipment. No abatement work of any kind described in the following provisions of these specifications will be initiated prior to the preabatement meeting . 2.1.2. PREABA TEMENT INSPECTION AND PREPARATIONS: Before any work begins on the containment barriers , the contractor will : 1. Conduct a space-by-space inspection with an authorized Owner's Representative , and prepare a written inventory of all existing damage in those spaces where asbestos re- Page 14 ASBESTOS REMOVAL moval work will occur . Still or video photography may be used to supplement this written damage inventory. Documents will be signed and certified as accurate by both part ies. 2. Ensure that all furniture , machinery , equipment , curtains drapes , blinds and other mov- able objects which the contractor is bound to remove from the work area have been re- moved or protected . 3. Notify the Owner's Representative of systems that need to be shut down as soon as pract ical in advance. The Owner's Representative will coordinate shutdown with Con- tractor and Owner's Facil ity Representative. The Owner's Facility Representative will perform and monitor shutdown as required by Contractor. a. Shutdown and seal off all heating, cooling, ventilating or other air handling systems serving the work area . The environment of the work area will be completely isolated from all other air flows in the building . Owner's Representative will monitor shut- down . b. Shut down all electrical circuits which pose a potential hazard on the job . Exact elec- trical arrangements will be tailored to the particular space and systems involved . All electrical circuits will be turned off at the box outside the removal area , not just the wall switch. Potential for electrical shock is a major threat to life in a work area where large amounts of water will be sprayed on ceilings, conduits, lighting fixtures and other electrical items. Electrical lines which are used to power work lights and equipment will conform to all electrical safety standards and will be protected by a ground fault interrupter. The Asbestos Abatement Contractor will be responsible for all OSHA lockout/tagout requirements. A copy of the Asbestos Abatement Contrac- tor's lockout/tagout program must be submitted for review prior to asbestos abate- ment operations . 2.1.3. PREABA TEMENT CONSTRUCT/ON AND OPERATIONS: Perform all preparatory work for the first work area in accordance with the approved detailed work schedule . Execute the preparatory work in accordance with this specification . Upon completion of all preparatory work , the Owner's Representative will inspect the work and systems to assure work is in accordance with these Specifications . The Owner's Representa- tive may require that , upon satisfactory inspection , the Contractor's employees perform all major aspects of the approved SOP especially on worker protection, respiratory protection , contin- gency plans, decontamination procedures and monitoring to demonstrate satisfactory operation . The operating systems for respiratory protection and negative pressure air systems will be demonstrated for performance . Upon satisfactory inspection of the installation and systems and satisfactory demonstration of operations the Owner's Representative will notify the Contractor to proceed with abatement work. 2.2. REMOVAL OF ACM AND ACE: 2.2.1. WETTING MATERIALS: The Asbestos Abatement Contractor will adequately wet and remove all ACM as follows : 1. Spray wetting agent on the asbestos containing materials. Page 15 ASBESTOS REMOVAL 2. After wetting and removal , seal all ACM waste in leaktight two layers of 6-mil polyethyl- ene while wet. For waste material not fitting into containers without additional breaking, put material into leaktight wrapping. 3. Label containers and wrapped material using warning labels as specified by OSHA 29 CFR 1910 .1001 or 1926 .1101 and the NESHAPS regulations . 4 . For ACM being transported off the facility site , label ACM waste containers and wrapped material with the name of the waste generator and the location where the waste was generated . 2.2.2. SITE PREPARATION: Erect cr itical barriers at all doors and windows entering the regulated areas . This project will be conducted by establishing critical barriers over all openings into the work area . A three stage wet decontamination unit will be erected for worker entrance and exit into the work area . The Contractor must establish negative air in the containment and maintain a pressure differential of -0.02 inches of water column pressure differential. 2.2.3. PERSONAL PROTECTION: One (1) layer of disposable clothing air-purifying respirators (PAPR) with NIOSH-approved HEPA cartridges shall be worn by all personnel during removal of the asbestos-containing ther- mal system insulation. Provide boots , safety glasses and gloves for all workers. Equipment will meet OSHA require- ments for personal protection. Provide all persons entering the work area with disposable full body coveralls , disposable head covers and rubber boots . 2.2.4. THERMAL SYSTEM INSULATION: The Contractor may remove the pipe insulation and elbows in a full containment or use a glove bag. If a glovebag is usued the procedures listed below will be used : The minimum crew size for a glovebag operation is two : one member performs the actual re- moval with "hands in the gloves" and the second directs the spray wand at the work . It is rec- ommended that three people be used. The third helps support the bag , makes sure tools and supplies are readily available , and is on hand in case of emergency. All crew members should be trained in the use of the glovebag . The Contractor will erect critical barriers and establish negative air filtration . Rope off work area and place warning signs. Bring the necessary materials into the work area. Have a HEPA vac- uum system available at all times . The HEPA vacuum will be used to establish negative air fil- tration inside of the glove bag. Make sure that possible contaminants in the area have been cleaned with the proper methods before beginning the glovebag procedure to avoid confusion concerning the source of the mate- rial. Wrap the adjacent pipe not to be enclosed in the glovebag with 6-mil plastic. Cover surfaces , such as the floor and walls , near the glovebag removal site with 6-mil plastic . Page 16 ASBESTOS REMOVAL Disposable cloth ing and full-face PAPR respirators will be worn be any pe rson performing glovebag removal. If fiber counts generated during abatement do not exceed the protection fac- tor of a half-face resp irator during glovebag removal of TSI , and this can be verified by on-site PCM fiber counts , a half-f ace respirator may be used . Wrap duct tape around the insulation where the shoulders of the glovebag will be attached. Put the necessary tools in the pouch of the glovebag . Slit the glovebag as necessary to fit it over the pipe from which insulation is to be removed. Attach the glovebag to the previously applied duct tape at the shoulders . Fold the top edge of the bag between shoulders over on itself about an inch , then staple it about every two inches . Fold it again and tape the folded edge to the bag . Seal all joints with duct tape . Prepare the opening for the spray wand . If the manufactured location is not accessible , be sure to reinforce the bag with duct tape where the slit is to be made. Slit must be covered with rub- ber septum-like material that will seal after the wand is removed. Be sure the sprayer and bag are properly supported. The glovebag will have to have a smoke test to assure that the bag is sealed . Assemble the tube and bulb . Insert the tube into the slit prepared for the spray wand . Fill the bag with smoke and gently squeeze. Watch for leaks particularly at seams , j oints , corners , and arms. Seal leaks with duct tape. Establish negative air filtration of the glovebag before any removal operations take place . Wet the covering of the insulation , keeping it wet through the entire operation. Remove any metal covering with the tin snips. Remove the outer covering of the insulation . This may expose wire that needs to be cut before proceeding. Be sure that sharp edges of metal and wire are folded inward to avoid puncturing the bag. It may be possible to further pro- tect the bag by packing insulation , which has already been removed from the pi pe and placed at the bottom of the bag , around sharp edged material. Remove the insulation. If possible , remove sections as they were installed . Otherwise use the util ity kn ife and/or the flex saw to cut out the section which is then pried off. Keep the insulation (especially newly exposed surfaces) wet during the procedure . As pieces of insulation are removed, lower them carefully to the bottom of the bag. Using the putty knife and the screwdriver , scrape any remaining residue from the pipe. Rinse the pipe while scraping . Clean the pipe with the scrub brush . Wipe all cleaned surfaces with a wet rag and put the rag in the bottom of the bag. Rinse and wipe the ins ide of the glovebag. Rinse and wipe the tools , then put them in the pouch. Develop a check list to inventory tools in the glovebag . Page 17 ASBESTOS REMOVAL Pull one arm out of the glovebag , inverting the glove in the process . With the other hand , place tools in the inverted glove. Grasp the remaining tools and place them in the other glove as the second arm is withdrawn. After the bag has been collapsed and the bottom twisted off, twist the gloves between the tool and the glovebag and wrap with tape for about four inches starting at the bag. Leave a tab and cut through the tape. Either transfer the glove to a new bag (if work is to continue) or open the bag under water and remove the tools , making sure they are free from debris. Remove the spray wand and insert the nozzle of the HEPA vacuum in the slit. Turn the vacuum on and run it long enough to collapse the bag. Twist the bag and wrap it with duct tape just below the gloves and remove the HEPA vacuum nozzle . Glovebags may only be used once and may not be moved . When the bag is finally to be removed from the pipe , fold the dirty side inward and put it in a 6- mil disposal bag . Seal the disposal bag. Inspect the sections of the pipe where the insulation has been removed. Remove any remain- ing material with a wet rag or the HEPA vacuum . Apply a coat of sealant to the pipe . Clean up any debris or water on the floor with wet rags and/or the HEPA vacuum . As in any asbestos related project, the work area should be kept free of debris . Any contamina- tion should be cleaned up immediately . When the work day is complete , (or as soon as the pro- ject is complete) the work area should be cleaned using wet methods and/or a HEPA vacuum . All glovebags should be removed from the pipes at the end of the work day (or as soon as the procedures are completed) and placed in double layer 6-mil asbestos disposal bags . Dispose of waste in accordance with regulations for asbestos waste found in these specifications. Workers should pass through a complete decontamination facility when exiting the work area. If the bag develops a leak, stop work inside the bag . Catch the water in a plastic disposal bag. Lift and move the bag so that water stops running out. Do not "pump" the bag in a way that would force air out. Twist the bag in the area of the puncture to form a stem, dry the surface and tape it securely closed . Clean up the contaminated water and debris from the floor immedi- ately using wet methods and/or the HEPA vacuum. Dispose of the waste properly. Alternate removal techniques may be used if approved by the CIH . 2.2.5. FLOOR TILE AND MASTIC: Those areas normally exposed to heavy foot traffic patterns usually have tiles adhered the tight- est. As a matter of good practice in starting the tile removal, those sections which receive the least traffic should be the locations selected for starting the removal of the tile . Since tiles are Page 18 ASBESTOS REMOVAL normally in a 9" x 9" or 12" x 12" dimension, it should be the goal to remove individual tiles as a complete unit to the best extent possible . Start the removal by carefully wedging the wall scraper in the seam of two adjoining tiles and gradually forcing the edge of one of the tiles up and away from the floor . Do not break off pieces of the tile but continue to force the balance of the tile up by working the scraper beneath the tile and exerting both a forward pressure and a twisting action on the blade to promote re- lease of the tile from the adhesive and the floor . When the first tile is removed , place it, without breaking into smaller pieces, in the heavy-duty impermeable waste bag or closed impermeable container which will be used for disposal. With the removal of the first tile accessibility of the other tiles is improved . Force the wall scraper under the exposed edge of another tile and continue to exert a prying twisting force to the scraper as it is moved under the tile until the tile released from the floor . Again, dispose of the tile, and succeeding tiles, by placing in the heavy-duty bag or closed container without additional breaking . Some tiles will release quite easily while others require varying degrees of force . Where the adhesive is spread heavily or is quite hard, it may prove easier to force the scraper through the tightly adhered areas by striking the scraper handle with a hammer using blows of moderate force while maintaining the scraper at a 25° to 30° angle to the floor. Caution: Use safety gog- gles. If some areas are encountered where even the technique detailed in the previous paragraph proves to be inadequate , the removal procedure can be simplified by thoroughly heating the tile(s) with a hot air blower until the heat penetrates through the tile and softens the adhesive. Note 1: Handle the hot air blower, tiles , and adhesive carefully to avoid personal burns . Note 2: Do not handle the heated tiles and adhesive without suitable glove protection for the hands . As small areas of subfloor are cleared of tile , the adhesive remaining on the floor must be scraped up with the 4" hand scraper until only a thin , smooth film remains . In those area where deposits are heavy or difficult to scrape , the removal can be expedited by heating with the hot air blower prior to scraping . Deposit scrapings in a heavy-duty impermeable trash bag or closed impermeable container . Thoroughly spread approved mastic biodegradable cleaner/solvent onto all mastic with a garden sprayer (Note The solvent used to remove the mastic must have a flash point of >140 degrees F. Submittals for the solvent must include a Material Safety Data Sheet. Let the solution stand for at least 15 minutes. Use an industrial buffer with coarse pads to dislodge the material or a squeegee . Squeegee , or use scrapers to push material into a cen- tral location for final mopping and cleanup . Hand-scraping may be done at the Contractor's op- tion, or as required to completely remove all material. As indicated in previous paragraphs , tiles should be placed immediately in a waste disposal bags or closed impermeable container. Do not attempt to break tiles after they are in the bag . Page 19 ASBESTOS REMOVAL When all tiles , mastic and sorbent material have been removed from the floor and placed in polyethylene waste bags at least 6-mil thick or closed containers , seal the bags securely for dis- posal. "Shot blaster" or "bead blaster" machines will not be allowed to remove the floor tile and mastic. Alternate removal techniques may be used if approved by the CIH . 2.2.6 WALL AND CEILING TEXTURE AND The asbestos texture will be kept wet and removed by wet scraping or as intact sheetrock and ceiling tile sections utilizing hand tools and a low water volume , short distance power diffusing "Airless" sprayer. The asbestos plaster texture and texture on CMU block will be kept wet and removed utilizing hand tools and a low water volume, short distance power diffusing "Airless" sprayer. The minimum crew size for the operation is three: one member performs the actual removal , the second directs the spray wand at the work and the third worker collects and contains the wet ACM debris generated during the work. It is recommended that four workers be utilized in the procedure. The fourth person provides support during the work , making sure tools and supplies are readily available, and is on hand in case of emergency. All crew members should be trained in the use of the wet scraping procedure . The Contractor will erect critical barriers and establish negative air filtration . Rope off work area and place warning signs . Bring the necessary materials into the work area. Have a HEPA vac- uum system available at all times. The HEPA vacuum will be used to remove debris which may settle in remote areas such as corners , cracks or crevices in the work area . Make sure visible ACM debris and dust in the area have been wetted with amended water and cleaned with the proper methods before beginning the procedure to avoid confusion concerning the source of the material. Cover floor with a minimum of two layers of 6 mil plastic sheeting if flooring is not being re- moved , and cover wall surfaces with a minimum of two layers of 4 mil plastic sheeting . The top polyethylene sheeting layer may be removed as part of the detail cleaning process after gross removal. Hard hats , disposable clothing and full-face PAPR respirators will be worn by all persons per- forming the ACM removal. Establish negative air filtration in the containment before any removal operations take place. The containment may be smoke tested to assure the negative pressure inside the containment is adequately sealed . Assemble the smoke tube and bulb . Generate short bursts of smoke in the containment particularly at seams , joints and corners and critical barriers . Observe the direc- tion of the smoke trail. Watch for leaks , and seal any leaks with duct tape . Wet the plaster and surfacing material adequately to suppress any generation of airborne dust or debris , keeping it wet throughout the entire operation. Page 20 ASBESTOS REMOVAL As sections of ACM are removed, keep the material wet and shovel debris carefully into the bot- tom of a disposal bag . Wipe all cleaned surfaces with a wet rag and put the rag in the bottom of a 6 mil disposal bag. Rinse and wipe the inside of the disposal bag . Clean up any debris or water on the floor with wet rags and/or the HEPA vacuum . As in any asbestos related project, the work area should be kept free of debris. Any contamina- tion should be cleaned up immediately. When the work day is complete , (or as soon as the pro- ject is complete) the work area should be cleaned using wet methods and a HEPA vacuum. All asbestos material and associated debris should be removed and placed in double layer 6 mil asbestos disposal bags before the end of the work day. Dispose of waste in accordance with regulations for asbestos waste found in these specifications. Workers should pass through a complete three-stage wet decontamination facility prio r to exit- ing the building. If a disposal bag develops a leak, stop work inside the containment. Catch the water in a plastic disposal bag . Lift and move the bag so that water stops running out. Do not "pump" the bag in a way that would force air out. Twist the bag in the area of the puncture to form a stem , dry the surface and tape it securely closed. Clean up the contaminated water and debris from the floor immediately using wet methods and the HEPA vacuum. Dispose of the waste properly. 2.3. DISPOSAL OF ACM AND ACE WASTE MATERIAL: 2.3.1. GENERAL: The Asbestos Abatement Contractor will dispose of friable ACM and debris which is packaged in accordance with these specifications at the approved landfill . Dispose of non-friable ACM in accordance with the applicable regulations for friable asbestos.

SUMMARY OF THE WORK 1.1.1. CONTRACT DOCUMENTS AND RELATED REQUIREMENTS: General provisions of the contract , including general and supplementary conditions , apply to the work of this section. The contract documents show the work of the contract and related re- quirements and conditions impacting the project. Related requirements and conditions include applicable codes and regulations , notices and permits , existing site conditions and restrictions on use of the site , requirements for partial owner occupancy during work , coordination with other work and phasing of work . Whenever there is a conflict or overlap of the above refer- ences , the more stringent provisions apply. 1.1.2. EXTENT OF WORK: A brief summary of the extent of the work and non-binding to the contract documents is as fol- lows : BASE BID: Removal and disposal of asbestos-containing materials (ACM) and asbestos-contaminated elements (ACE) utilizing wet methods within full, negative-pressure containments equipped with HEPA ventilation from specified areas of the buildings. The following asbestos-containing ma- terials (ACM) will be removed at the property where applicable . 350 Belknap, Fort Worth, Texas Floor tile and mastic 3,172 square feet Areas A, B, C, D, &F The Work Area will be inclusive of the locations and the quantities noted above , in the attached drawings , and as directed by a representative of IHST . The Work may be broken down into multiple Work Areas at the discretion of the Contractor. However, the Contractor will receive no additional time to perform the work on the basis of having multiple Work Areas and associated Cleaning Sequences . The Contractor will be responsible for the removal and disposal of the asbestos-containing ma- terial and asbestos-contaminated materials in accordance with Texas Department of State Health Services (TDSHS), OSHA 29 CFR 1926.1101 , Asbestos Hazard Emergency Response Act (AHERA) 40 CFR Part 763, and the National Emission Standards for Hazardous Air Pollut- ants (NESHAP) Regulations 40 CFR Part 61 . )/~I( ~(f DSHS License 10-5040 Expires 12-31 -0911 Page 1 ASBESTOS REMOVAL The CONTRACTOR shall be responsible for verifying existing site conditions and determining the quantity of ACM delineated for removal prior to abatement described in these specifications and associated drawings . 1.1.3. TASKS: The work , located at the facility , is summarized briefly as follows : The PROJECT requires the removal of the materials outlined in Section 1.1 .2. The asbestos abatement will be performed in accordance with these specifications and procedures as out- lined. Power and Water Connections: The City will supply water and power for this project. Asbestos Removal within full Containment: The Contractor will use wet methods for all re- moval operations . The Contractor is responsible for prompt clean-up and disposal of waste and debris contaminated with asbestos in leak tight containers. The Contractor will conduct a wet decontamination of equipment and tools before final clearance sampling in the work area. The Contractor will use the existing interior walls and will have to build a false ceiling above the plaster lathe which will be removed to provide structural support for an asbestos containment work area provided the containment remains sound and is not in danger of collapse . The Con- tractor should make every effort not to damage the interior walls of the building during the pro- ject. The Contractor will establish critical barriers over all openings into the work area. ACM debris should be adequately wetted prior to establishing perimeter critical barriers The full containment design must be structurally sound so that it will not collapse under negative pressure and work conditions . A structurally unsound containment design will not be ac- cepted. The full containment design will consist of one (1) layer of 6-mil polyethylene sheeting for all critical barriers , floors and walls . Two layers of polyethylene sheeting will be required on walls and floors not affected by the abatement Polyethylene sheeting shall meet the requirements in accordance with current TDSHS rules . The Contractor must establish negative air into the containment and maintain a pressure differential of -0.02 inches of water as indicated by a working manometer. After the ACM has been removed and the work area cleaned , a detailed visual clearance in- spection will be conducted to determine if ACM or asbestos-contaminated elements (ACE) re- main prior to final clearance and work completion . OSHA personnel and area monitoring will be conducted with analysis by (PCM). Final air clearance sampling will be conducted utilizing PCM. Before the containment can be removed, the area must be cleared per the mold protocol. Respiratory protection will require half-face , air-purifying respirators (APR) with NIOSH- approved P-100 (HEPA) cartridges during removal. )/t'l4Utf-I(· ~/£ DSHS License 10-5040 Expires 12-31-11 Page 2 ASBESTOS REMOVAL The CONTRACTOR is responsible to verify site conditions and estimated quantities of ACM to be removed. 1.1.4.

RESP/RA TORS FOR ASA TEMENT OPERATIONS: Where a person is or could reasonably be expected to be exposed during abatement operations to airborne asbestos above 0.1 flee or where ACM debris is visible , the following maximum level of respiratory protection is required : If it is reasonably anticipated that fiber counts generated during abatement will not exceed the protection factor of a half-face respirator, and this can be verified by on-site fiber counts , a half-face respirator may be used. If verification cannot be made , a full face PAPR must be used. PAPR must be used for friable surfac- ing or thermal system insulation removal until fiber counts are confirmed consis- tently below the PEL and STEL. Head coverings: PAPR respirators will be equipped with full facepieces . Full facepieces will be worn with either a bonnet-type disposable head cover/hood or with a full head cover/hood which is part of a fully encapsulating protective garment. Respirator straps will be located under the hoods. This allows removal of the head covering prior to showering without disturbing the respi- rator (which is worn into the shower). Exemptions from maximum respiratory protection during abatement operations : When the abatement contractor has demonstrated to the Owner's satisfaction that levels of airborne as- bestos fibers in the work area are consistently below 0.1 flee , a full facepiece or half face respi- rator with HEPA cartridges may be used. The Certified Industrial Hygienist will determine if a lesser form of respiratory protection may be used. 1.7. WORKER PROTECTION: 1.7.1.

Provide adequately sized DF to accommodate the number of employees scheduled for the project. The center chamber of the three chamber OF will be fitted with as many portable walk through shower stalls as necessary so that all employees will be able to go through the en- tire decontamination procedure within 15 minutes. Construct OF of opaque or colored polyethyl- ene for privacy. Construct OF so that it will not allow for parallel routes of exit without shower- ing. 1.9. NEGATIVE PRESSURE FILTRATION SYSTEMS: The Asbestos Abatement Contractor will provide enough HEPA-filtered negative air units to completely exchange the work air four (4) times per hour. Contractor will demonstrate the num- ber of units needed per work area for 4 room air changes by calculating the volume flow rate (cfm) delivered by each unit under 2" pressure drop across filters . Provide at least one standby unit in the event of a machine failure or emergency such as contamination in surrounding non- work area . When a pressure differential system is selected provide enough HEPA filtration units to filter and recirculate the air in the work area at a rate of four (4) room air changes per hour. 1.9.2. PRESSURE DIFFERENTIAL: Provide a fully operational negative air system within the work area continuously maintaining a pressure differential across work area enclosures of -0.02 inches of water. Demonstrate to the Owner's Representative the pressure differential by use of a pressure differential meter or a manometer, before disturbance of any asbestos containing materials. This pressure differential will be used for either negative air system or pressure differential system. 1.9.3. MONITORING: Continuously monitor and record the pressure differential between the work area and the build- ing outside of the work area with a monitoring device incorporating a strip chart recorder. Make the strip chart record part of the project log. Page 9 ASBESTOS REMOVAL 1.9.4. TESTING THE SYSTEM: Test negative-pressure system before any ACM is wetted or removed . After the work area has been prepared, the decontamination facility set up, and the exhaust unit(s) installed , start the unit(s) (one at a time). Demonstrate operation and testing of negative-pressure system to the Owner's Representative . 1.9.5. DEMONSTRATION OF NEGATIVE AIR SYSTEM OPERATION: Demonstrate the operation of the negative-pressure system to the Owner's Representative to include, but not be limited to , the following : 1. Demonstrate pressure differential system will maintain -0.02" of water . 2 . Emergency shutoff will operate in case of fire . 1.9.6. USE OF SYSTEM DURING ABATEMENT OPERATIONS: Start exhaust units before beginning work (before any ACM is disturbed). After abatement work has begun , run units continuously to maintain a constant negative-pressure until decontamina- tion of the work area is complete. Do not turn off units at the end of the work shift or when abatement operations temporarily stop. Do not shut down negative air system during abatement operations procedures , unless author- ized by the Owner's Representative in writing . The systems may be shut down daily if air moni- toring in the containment shows airborne levels of less than 0.01 fibers/cc. Start abatement work at a location farthest from the exhaust units and proceed toward them. If an electric power failure occurs , immediately stop all removal work and do not resume until power is restored and all exhaust units are operating again . At completion of abatement work, allow exhaust units to run as specified under this sect ion , to remove airborne fibers that may have been generated during abatement work and cleanup and to purge the work area with clean makeup air. Units may be required to run after decontamina- tion , if dry or only partially wetted asbestos material was encountered during any abatement work . 1.9.7. DISMANTLING THE SYSTEM: When a final inspection and the results of the final air tests indicate that the area has been de- contaminated , exhaust units may be removed from the work area . Before removal from the work area , remove and properly dispose of pre-filters , and seal intake to the machine with 6-mil polyethylene to prevent environmental contamination from the pre-filters . 1.10. CONTAINMENT BARRIERS AND COVERINGS OF WORK AREA: 1.10.1. GENERAL: Seal off perimeter of work area to completely isolate abatement areas and to contain all air- borne asbestos contamination created by abatement work . Cover all surfaces of the work area to protect them from cross contamination , to facilitate more efficient cleanup , and to protect the finishes from the asbestos abatement work . Should the area beyond the seal off limits become Page 10 ASBESTOS REMOVAL contaminated as a consequence of the work, clean those areas in accordance with procedures described in this section at no additional cost. 1.10.2. PREPARATION PRIOR TO SEALING OFF: Place all tools , staging , etc. necessary for the work in the area to be isolated prior to erection of temporary plastic sheeting enclosure . Disable ventilating systems or any other system bringing air into or out of the work area. Disable system utilizing positive means that will prevent acci - dental premature restarting of equipment, i.e ., disconnecting wires , removing circuit breakers , lockable switch , etc. 1.10.3. CONTROL ACCESS TO WORK AREA: Permit access to the work area only through the DF . All other means of access will be closed off and sealed and warning signs displayed on the clean side of the sealed access . Where the work area is immediately adjacent to or within view of occupied areas , provide a visual barrier of opaque polyethylene sheeting at least 6-mil in thickness so that the work procedures are not visible to building occupants . Where the area adjacent to the work area is accessible to the public , construct a barrier of plywood or other suitable material at least eight feet (8') in height that is able to withstand the negative pressure as specified. Post warning signs at each visual and physical barrier per OSHA requirements . Alternate method of containing the work area or different definition of the limits of seal-off from the one shown on the drawings may be submitted to the Owner's Representative for approval in accor- dance with this section . Do not proceed with any such alternatives without prior written approval by the Owner's . 1.10.4. CRITICAL BARRIERS: Completely separate the work area from other portions of the building , and the outside by sheet polyethylene barriers at least 6 mil in thickness and sealing with duct tape. Individually seal all ventilation openings (supply and exhaust), lighting fixtures , doorways, windows , and other open- ings into the work area with duct tape alone and with polyethylene sheeting at least 6-mil in thickness , taped securely in place with duct tape. Maintain seal until all work including project decontamination is completed . Take care in sealing off lighting fixtures to avoid melting or burn- ing of sheeting . Provide sheet plastic barriers at least 6-mil in thickness as required to com- pletely seal openings from the work area into adjacent areas . Seal the perimeter of all sheet plastic barriers with duct tape or spray cement. 1.10.5. PRIMARY BARRIERS: The primary barrier of the full containment walls will consist of a minimum of Primary barriers for full containment shall consist of two (2) layers of minimum 4-mil polyethylene sheeting for the walls securely anchored from the floors to the ceiling. The containment for the removal of the li- noleum flooring will require a minimum 4-mil polyethylene sheeting for the ceiling . Polyethylene sheeting shall meet ASTM requirements in accordance with TDSHS regulations . Visible open- ings observed along the perimeter walls and the ceiling shall be completely sealed polyethylene sheeting and the wall corners of the containment should be attached with an overlap of at least twelve inches . The primary barrier construction should form an airtight , impermeable, perma- nent barrier around the ACM and ACM debris to contain the release of asbestos fibers into the air. Page 11 ASBESTOS REMOVAL 1.10.6. EXTENSION OF WORK AREA: If the enclosure barrier is breached in any manner that could allow the passage of asbestos de- bris or airborne fibers , then where possible , add affected area to the work area . Enclose it as required by this Section of the specification and decontaminate it as described elsewhere in this section . If contaminated area cannot be added to work area , decontamination measures will start immediately after contamination is discovered and work will stop in work area. Decontami- nation procedures will continue until exposure returns to background levels . 1.10.7. SECONDARY BARRIERS: Secondary barriers should be established in areas to separate any non-related work activity from the abatement containment to prevent dust or debris from potentially contaminating fresh air (make-up air) into the containment or regulated asbestos removal area . 1.11. MONITORING, INSPECTION AND TESTING: 1.11.1. GENERAL: Perform throughout abatement work monitoring , inspection and testing inside the work area in accordance with OSHA requirements and these specifications . I.H . Technician will continuously inspect and monitor conditions inside the work area to ensure compliance with these specifica- tions. In addition, the I.H . will personally manage air sample collection , analysis and evaluation for personnel and work area samples to satisfy OSHA requirements . Additional inspection and testing requirements are specified in other parts of this section. The Owner will employ a Certified Industrial Hygienist (C.I.H.) representative to perform various services on behalf of the Owner. The C.I.H. representative or representative under the direction of a C.I.H . will perform the necessary monitoring , inspection , testing and other support services to ensure that the Owner , employees and visitors will not be adversely impacted by the abate- ment worked, and that the abatement work proceeds in accordance with these specifications , that the abated areas or abated buildings have been successfully decontaminated. The work of the C.I.H . representative in no way relieves the abatement Contractor from his responsibility to perform his work in accordance with contract documents , to perform continuous inspection, monitoring and testing for the safety of his employees, and to perform other such services as specified in this section . The cost of the CIH representative and his services will be born by the Owner except for repeated final inspection and testing that may be required due to unsatisfac- tory initial results. These repeated final inspections and testing, if required , will be paid for by the Contractor. The Asbestos Abatement Contractor may request confirmation of above results . This request must be in writing and submitted to the Owner's Representative. Cost for the confirmation of re - sults will be born by the Contractor for both the collection and analysis of samples and for the time delay that may result for this confirmation. Confirmation sampling and analysis will be the responsibility of the Contractor with review and approval by the C.I.H. Page 12 ASBESTOS REMOVAL 1.11.2.

All data , inspection results and testing results generated by the Owner's Representative will be available to the Contractor for information and consideration . Contractor will provide coopera- tion and support to the Owner's Representative for efficient and smooth performance of their work. Monitoring and inspection results of the Owner's Representative will be used by the Owner to issue any Stop Asbestos Removal Orders to the contractor during abatement work and to ac- cept or reject an area or a building as decontaminated. The Owner's Representative will make available to the Contractor the plan for sample collection and analysis for continuous monitoring outside the work areas and the plan of final inspection and testing for each space or building prior to executing each plan . Plan will include location for samples, name and qualification of person taking samples , whether on site analysis and/or lab analysis will be utilized , methodol- ogy of analysis , lab information and qualifications of on-site analyst. 1.11.3. MONITORING, INSPECTION AND TESTING BY ABATEMENT CONTRACTOR: The Contractor is responsible for managing all monitoring , inspection and testing required by these specifications and the OSHA requirements. Page 13 ASBESTOS REMOVAL The analytical laboratory that will be used by the Contractor to analyze the samples will be AIHA P.A.T. Accredited and Texas Department of State Health Services Licensed . Keep a daily log of personnel samples taken and analyzed and make log available to the Owner's Representa- tive . Log will contain information on the persons sampled , the date of sample collection the time of sample start and finish , flow rate , sample volume and fibers/cc. Take and analyze personnel samples for at least 25% of the workers in each shift , but not less than two where active abate- ment takes place. 1.11.4. ANALYSIS: Bulk samples (if required) will be analyzed at a laboratory that is Accredited by the National Vol- untary Laboratory Accreditation Program (NVLAP). Proof of accreditation must be submitted prior to the project start date . Polarized light microscopy will be used to analyze bulk samples . Air samples will be analyzed by an individual participating in the American Industrial Hygiene Association's (AIHA) Proficiency Analytical Testing Program. In addition to the continuous monitoring required , the Owner's Representative will perform in - spection and testing at the final stages of abatement for each work area or building as specified elsewhere in this section. 1.12.5. SUBMITTALS AT COMPLETION OF ABATEMENT: The Contractor will submit a final project report consisting of the daily log book and the docu- mentation of events during abatement including the original disposal manifests signed by the operator of licensed landfill. The project report will include a certificate of completion , dated and signed by the Contractor. All certificates and original disposal manifests are due to the Owner's Representative office within 30 (thirty) days after completion of abatement work. PART 2 -EXECUTION 2.1. PREABATEMENT ACTIVITIES: 2.1.1. PREABA TEMENT MEETING: The Owner's Representative , upon receipt, review and substantial approval of all preabatement submittals and upon verification that all material and equipment required for the project are on site , will arrange for a preabatement meeting between the Asbestos Abatement Contractor , su- perintendent and foremen and the Owner's Representatives. The purpose of the meeting is discuss any aspects of the submittals needing clarification or amplification and to discuss any aspects of the project execution and the sequence of operations . The Asbestos Abatement Contractor and his employees will be prepared to provide any sup- plemental evidence and information to the Owner's Representative pertaining to any aspects of the submittals or the materials and equipment. No abatement work of any kind described in the following provisions of these specifications will be initiated prior to the preabatement meeting. 2.1.2. PREABA TEMENT INSPECTION AND PREPARATIONS: Before any work begins on the containment barriers , the contractor will: 1. Conduct a space-by-space inspection with an authorized Owner's Representative, and prepare a written inventory of all existing damage in those spaces where asbestos re- Page 14 ASBESTOS REMOVAL moval work will occur. Still or video photography may be used to supplement this written damage inventory. Documents will be signed and certified as accurate by both parties . 2 . Ensure that all furniture , machinery , equipment, curtains drapes , blinds and other mov- able objects which the contractor is bound to remove from the work area have been re- moved or protected. 3. Notify the Owner's Representative of systems that need to be shut down as soon as practical in advance. The Owner's Representative will coordinate shutdown with Con- tractor and Owner's Facility Representative . The Owner's Facility Representative will perform and monitor shutdown as required by Contractor . a. Shutdown and seal off all heating , cooling, ventilating or other air handling systems serving the work area. The environment of the work area will be completely isolated from all other air flows in the building. Owner's Representative will monitor shut- down . b. Shut down all electrical circuits which pose a potential hazard on the job . Exact elec- trical arrangements will be tailored to the particular space and systems involved. All electrical circuits will be turned off at the box outside the removal area , not just the wall switch . Potential for electrical shock is a major threat to life in a work area where large amounts of water will be sprayed on ceilings , conduits , lighting fixtures and other electrical items . Electrical lines which are used to power work lights and equipment will conform to all electrical safety standards and will be protected by a ground fault interrupter. The Asbestos Abatement Contractor will be responsible for all OSHA lockout/tagout requirements. A copy of the Asbestos Abatement Contrac- tor's lockout/tagout program must be submitted for review prior to asbestos abate- ment operations . 2.1.3. PREABATEMENT CONSTRUCTION AND OPERATIONS: Perform all preparatory work for the first work area in accordance with the approved detailed work schedule. Execute the preparatory work in accordance with this specification . Upon completion of all preparatory work , the Owner's Representative will inspect the work and systems to assure work is in accordance with these Specifications . The Owner's Representa- tive may require that , upon satisfactory inspection , the Contractor's employees perform all major aspects of the approved SOP especially on worker protection , respiratory protection , contin - gency plans , decontamination procedures and monitoring to demonstrate satisfactory operation . The operating systems for respiratory protection and negative pressure air systems will be demonstrated for performance . Upon satisfactory inspection of the installation and systems and satisfactory demonstration of operations the Owner's Representative will notify the Contractor to proceed with abatement work. 2.2. REMOVAL OF ACM AND ACE: 2.2.1. WETTING MATERIALS: The Asbestos Abatement Contractor will adequately wet and remove all ACM as follows : 1. Spray wetting agent on the asbestos containing materials . Page 15 ASBESTOS REMOVAL 2 . After wetting and removal, seal all ACM waste in leaktight two layers of 6-mil polyethyl- ene while wet. For waste material not fitting into containers without additional breaking , put material into leaktight wrapping. 3. Label containers and wrapped material using warning labels as specified by OSHA 29 CFR 1910.1001 or 1926.1101 and the NESHAPS regulations . 4. For ACM being transported off the facility site, label ACM waste containers and wrapped material with the name of the waste generator and the location where the waste was generated . 2.2.2. SITE PREPARATION: Erect critical barriers at all doors and windows entering the regulated areas. This project will be conducted by establishing critical barriers over all openings into the work area. A three stage wet decontamination unit will be erected for worker entrance and exit into the work area . The Contractor must establish negative air in the containment and maintain a pressure differential of -0.02 inches of water column pressure differential. 2.2.3. PERSONAL PROTECTION: One (1) layer of disposable clothing air-purifying respirators (PAPR) with NIOSH-approved HEPA cartridges shall be worn by all personnel during removal of the asbestos-containing ther- mal system insulation . Provide boots , safety glasses and gloves for all workers . Equipment will meet OSHA require- ments for personal protection. Provide all persons entering the work area with disposable full body coveralls , disposable head covers and rubber boots . 2.2.4. THERMAL SYSTEM INSULATION: The Contractor may remove the pipe insulation and elbows in a full containment or use a glove bag. If a glovebag is usued the procedures listed below will be used: The minimum crew size for a glovebag operation is two : one member performs the actual re- moval with "hands in the gloves" and the second directs the spray wand at the work. It is rec- ommended that three people be used . The third helps support the bag , makes sure tools and supplies are readily available, and is on hand in case of emergency . All crew members should be trained in the use of the glovebag . The Contractor will erect critical barriers and establish negative air filtration. Rope off work area and place warning signs. Bring the necessary materials into the work area . Have a HEPA vac- uum system available at all times . The HEPA vacuum will be used to establish negative air fil- tration inside of the glove bag . Make sure that possible contaminants in the area have been cleaned with the proper methods before beginning the glovebag procedure to avoid confusion concerning the source of the mate- rial. Wrap the adjacent pipe not to be enclosed in the glovebag with 6-mil plastic . Cover surfaces , such as the floor and walls, near the glovebag removal site with 6-mil plastic . Page 16 ASBESTOS REMOVAL Disposable clothing and full-face PAPR respirators will be worn be any person performing glovebag removal. If fiber counts generated during abatement do not exceed the protection fac- tor of a half-face respirator during glovebag removal of TSI , and this can be verified by on-site PCM fiber counts , a half-face respirator may be used. Wrap duct tape around the insulation where the shoulders of the glovebag will be attached . Put the necessary tools in the pouch of the glovebag . Slit the glovebag as necessary to fit it over the pipe from which insulation is to be removed. Attach the glovebag to the previously applied duct tape at the shoulders. Fold the top edge of the bag between shoulders over on itself about an inch, then staple it about every two inches . Fold it again and tape the folded edge to the bag . Seal all joints with duct tape. Prepare the opening for the spray wand. If the manufactured location is not accessible , be sure to reinforce the bag with duct tape where the slit is to be made . Slit must be covered with rub- ber septum-like material that will seal after the wand is removed. Be sure the sprayer and bag are properly supported . The glovebag will have to have a smoke test to assure that the bag is sealed. Assemble the tube and bulb . Insert the tube into the slit prepared for the spray wand. Fill the bag with smoke and gently squeeze. Watch for leaks particularly at seams , joints, corners , and arms . Seal leaks with duct tape. Establish negative air filtration of the glovebag before any removal operations take place. Wet the covering of the insulation, keeping it wet through the entire operation . Remove any metal covering with the tin snips . Remove the outer covering of the insulation . This may expose wire that needs to be cut before proceeding . Be sure that sharp edges of metal and wire are folded inward to avoid puncturing the bag. It may be possible to further pro- tect the bag by packing insulation , which has already been removed from the pipe and placed at the bottom of the bag , around sharp edged material. Remove the insulation. If possible , remove sections as they were installed . Otherwise use the utility knife and/or the flex saw to cut out the section which is then pried off. Keep the insulation (especially newly exposed surfaces) wet during the procedure. As pieces of insulation are removed, lower them carefully to the bottom of the bag. Using the putty knife and the screwdriver, scrape any remaining residue from the pipe . Rinse the pipe while scraping. Clean the pipe with the scrub brush. Wipe all cleaned surfaces with a wet rag and put the rag in the bottom of the bag. Rinse and wipe the inside of the glovebag. Rinse and wipe the tools , then put them in the pouch. Develop a check list to inventory tools in the glovebag . Page 17 ASBESTOS REMOVAL Pull one arm out of the glovebag, inverting the glove in the process. With the other hand , place tools in the inverted glove. Grasp the remaining tools and place them in the other glove as the second arm is withdrawn. After the bag has been collapsed and the bottom twisted off, twist the gloves between the tool and the glovebag and wrap with tape for about four inches starting at the bag . Leave a tab and cut through the tape . Either transfer the glove to a new bag (if work is to continue) or open the bag under water and remove the tools , making sure they are free from debris . Remove the spray wand and insert the nozzle of the HEPA vacuum in the slit. Turn the vacuum on and run it long enough to collapse the bag . Twist the bag and wrap it with duct tape just below the gloves and remove the HEPA vacuum nozzle . Glovebags may only be used once and may not be moved. When the bag is finally to be removed from the pipe , fold the dirty side inward and put it in a 6- mil disposal bag . Seal the disposal bag. Inspect the sections of the pipe where the insulation has been removed. Remove any remain- ing material with a wet rag or the HEPA vacuum . Apply a coat of sealant to the pipe. Clean up any debris or water on the floor with wet rags and/or the HEPA vacuum . As in any asbestos related project , the work area should be kept free of debris. Any contamina- tion should be cleaned up immediately. When the work day is complete, (or as soon as the pro- ject is complete) the work area should be cleaned using wet methods and/or a HEPA vacuum . All glovebags should be removed from the pipes at the end of the work day (or as soon as the procedures are completed) and placed in double layer 6-mil asbestos disposal bags . Dispose of waste in accordance with regulations for asbestos waste found in these specifications. Workers should pass through a complete decontamination facility when exiting the work area . If the bag develops a leak , stop work inside the bag . Catch the water in a plastic disposal bag. Lift and move the bag so that water stops running out. Do not "pump" the bag in a way that would force air out. Twist the bag in the area of the puncture to form a stem , dry the surface and tape it securely closed. Clean up the contaminated water and debris from the floor immedi- ately using wet methods and/or the HEPA vacuum . Dispose of the waste properly. Alternate removal techniques may be used if approved by the CIH . 2.2.5. FLOOR TILE AND MASTIC: Those areas normally exposed to heavy foot traffic patterns usually have tiles adhered the tight- est. As a matter of good practice in starting the tile removal , those sections which receive the least traffic should be the locations selected for starting the removal of the tile . Since tiles are Page 18 ASBESTOS REMOVAL normally in a 9" x 9" or 12" x 12 " dimension , it should be the goal to remove individual tiles as a complete unit to the best extent possible . Start the removal by carefully wedging the wall scraper in the seam of two adjo ining tiles and gradually forcing the edge of one of the tiles up and away from the floo r. Do not break off pieces of the tile but continue to force the balance of the t ile up by working the scraper beneath the tile and exerting both a forward pressure and a twisting action on the blade to promote re- lease of the tile from the adhes ive and the floor . When the first tile is removed , place it , without breaking into smaller pieces , in the heavy-duty impermeable waste bag or closed impermeable container which will be used for disposal. With the removal of the first tile accessibility of the other tiles is improved . Force the wall sc raper under the exposed edge of another tile and continue to exert a prying twisting force to the scraper as it is moved under the tile until the tile released from the floor . Again , dispose of the tile , and succeeding tiles , by placing in the heavy-duty bag or closed conta iner without additional breaking . Some tiles w ill release quite easily while others require varying degrees of fo rce. Where the adhesive is spread heavily or is quite hard , it may prove eas ier t o force the scraper through the tightly adhered areas by striking the scraper handle with a hammer us ing blows of moderate force while ma intaining the scraper at a 25° to 30° angle to the floor. Caution: Use safety gog- gles. If some areas are encountered where even the technique detailed in the previous paragraph proves to be inadequate , the removal procedure can be simplified by thoroughly heating the tile(s) with a hot air blower until the heat penetrates through the ti le and softens the adhes ive. Note 1: Handle the hot air blower , tiles , and adhesive carefully to avoid personal burns. Note 2: Do not handle the heated tiles and adhesive without suitable glove protection for the hands. As small areas of subfloor are cleared of tile , the adhesive remaining on the floor must be scraped up with the 4" hand scraper until only a thin , smooth film remains . In those area where deposits are heavy or difficult to scrape , the removal can be expedited by heating with the hot air blower prior to scraping . Deposit scrapings in a heavy-duty impermeable trash bag or closed impermeable container. Thoroughly spread approved mastic biodegradable cleaner/solvent onto all mastic with a garden sprayer (Note The solvent used to remove the mastic must have a flash point of >140 degrees F. Submittals for the solvent must include a Material Safety Data Sheet. Let the solution stand for at least 15 minutes . Use an industrial buffer with coarse pads to dislodge the material or a squeegee . Squeegee , or use scrapers to push material into a cen- tral location for final mopping and cleanup . Hand-scraping may be done at the Contractor's op- tion , or as required to completely remove all material. As indicated in previous paragraphs , tiles should be placed immediately in a waste disposal bags or closed impermeable container. Do not attempt to break tiles after they are in the bag . Page 19 ASBESTOS REMOVAL When all tiles , mastic and sorbent material have been removed from the floor and placed in polyethylene waste bags at least 6-mil thick or closed containers , seal the bags securely for d is- posal. "Shot blaster" or "bead blaster" machines will not be allowed to remove the floor tile and mastic . Alternate removal techniques may be used if approved by the CIH . 2.2.6 WALL AND CEILING TEXTURE AND The asbestos texture will be kept wet and removed by wet scraping or as intact sheetrock and ceiling tile sections utilizing hand tools and a low water volume , short distance power diffusing "Airless" sprayer. The asbestos plaster texture and texture on CMU block will be kept wet and removed utilizing hand tools and a low water volume , short distance power diffusing "Airless" sprayer. The minimum crew size for the operation is three: one member performs the actual removal , the second directs the spray wand at the work and the third worker collects and contains the wet ACM debris generated during the work . It is recommended that four workers be utilized in the procedure . The fourth person provides support during the work , making sure tools and supplies are readily available , and is on hand in case of emergency . All crew members should be trained in the use of the wet scraping procedure . The Contractor will erect critical barriers and establish negative air filtration . Rope off work area and place warning signs . Bring the necessary materials into the work area . Have a HEPA vac- uum system available at all times . The HEPA vacuum will be used to remove debris which may settle in remote areas such as corners , cracks or crevices in the work area . Make sure visible ACM debris and dust in the area have been wetted with amended water and cleaned with the proper methods before beginning the procedure to avoid confusion concerning the source of the material. Cover floor with a minimum of two layers of 6 mil plastic sheeting if flooring is not being re- moved, and cover wall surfaces with a minimum of two layers of 4 mil plastic sheeting . The top polyethylene sheeting layer may be removed as part of the detail cleaning process after gross removal. Hard hats , disposable clothing and full-face PAPR respirators will be worn by all persons per- forming the ACM removal. Establish negative air filtration in the containment before any removal operations take place. The containment may be smoke tested to assure the negative pressure inside the containment is adequately sealed. Assemble the smoke tube and bulb . Generate short bursts of smoke in the containment particularly at seams, joints and corners and critical barriers . Observe the direc- tion of the smoke trail. Watch for leaks , and seal any leaks with duct tape . Wet the plaster and surfacing material adequately to suppress any generation of airborne dust or debris , keeping it wet throughout the entire operation. Page 20 ASBESTOS REMOVAL As sections of ACM are removed , keep the material wet and shovel debris carefully into the bot- tom of a disposa l bag . Wipe all cleaned surfaces with a wet rag and put the rag in the bottom of a 6 mil disposal bag. Rinse and wipe the inside of the disposal bag . Clean up any debris or water on the floor with wet rags and/or the HEPA vacuum . As in any asbestos related project , the work area should be kept free of debris . Any contamina- tion should be cleaned up immediately. When the work day is complete , (or as soon as the pro- ject is comp lete) the work area should be cleaned using wet methods and a HEPA vacuum . All asbestos material and associated debris should be removed and placed in double layer 6 mil asbestos disposal bags before the end of the work day . Dispose of waste in accordance with regulations for asbestos waste found in these specifications. Workers should pass through a complete three-stage wet decontamination facility prior to exit- ing the building. If a disposal bag develops a leak , stop work inside the containment. Catch the water in a plastic disposal bag . Lift and move the bag so that water stops running out. Do not "pump " the bag in a way that would force air out. Twist the bag in the area of the puncture to form a stem , dry the surface and tape it securely closed . Clean up the contaminated water and debris from the floor immediately using wet methods and the HEPA vacuum . Dispose of the waste properly . 2.3. DISPOSAL OF ACM AND ACE WASTE MATERIAL: 2.3.1. GENERAL: The Asbestos Abatement Contractor will dispose of friable ACM and debris which is packaged in accordance with these specifications at the approved landfill.

Lead Bullets vs. Lead Shot: More information is necessary on the difference between lead bi.tllets versus lead shot. A description of the methodology used to identify the extent of contaminated soir is needed, particularly the area of shot fall from the shotgun ranges. If this information has been previously provided in other repbtt~r, those reports should be cited. A discussion of how lead shot and bullet fragments are affected by storm water transport should be provided. It would also be useful to know what lab issues may arise when analyzing the two ammunition types (e.g., sieving). An explanation of how the breakdown of lead bullets versus lead shot in the environment may differ should also be provided. ·No -differentiation of any kind was noted in the report. 2~ Further Remedial Activities: It is mentioned that additional site remedial activities are planned; however, these activities are not specified in the submitted document. The comments in this memo are based on the information submitted to date. If remedial activities take place in the future, the review of the ERA will be revisited based on the response to comments associated with this memo, inclusion of any new groundwater and/ or soil data, and associated revisions to the ER,A. However, it should be noted that unless site remediation activities result in a representative lead concentration that is at or below 15 mg/kg (statewide median background value) or an approved site background concentration, further ecological evaluation to address the bioaccurnulative potential of lead in soil will be required. Texas Commission on Environmental Quality TCEQ Interoffice Memorandum 3. Rangel: Please provide sample information and sample locations associated with Range I as these data were not provided in the report submitted. 4. Laboratory Methods for Sieving: Information regarding the technique used by the lab to process lead samples should be provided. Any sieving technique used to remove lead shot/bullet fragments should be adequately identified and described in detail. 5. Arsenic More information is needed regarding why arsenic was not evaluated during the ERA even though it previously was considered a site contaminant. Section Specific Comments: 6. Section 2.4 Investigation History: It is mentioned in this section that 18,000 cubic yards of arsenic and lead contaminated soils were removed from the site. However; arsenic is not identified as a chemical of concern ( COC) in the ERA. More information is needed regarding why arsenic was not evaluated during the ERA even though it previously was considered a COC. 7. Section 3.0 Tier 1 ERA: For future reference, the Tier 1 ERA is the Exclusion Criteria Checklist and the Tier 2 ERA is the screening level ecological risk assessment (SLERA). Also, it is because the potential exists for contaminated site soils to migrate to surface waters/sediments in the state that the site does not meet the surface water/sediment exposure exclusion criteria. 8. Section 4.0 Tier 2 ERA: A Tier 2 SLERA that evaluates the uptake of site COCs via the food chain and incidental soil ingestion by ecological receptors is needed. 9. Section 4.1.3.3 Surface Soils: The site is considered accessible and potentially attractive to mobile and wide-ranging ecological receptors. It should be kept in mind that lead is considered to be bioaccumulative when found in soil. The bioaccumulation evaluation, including any Texas Commission on Environmental Quality TCEQ Interoffice Memorandum site-specific considerations, should be conducted during the food chain analysis as part of the Tier 2 SLERA required by the Texas Risk Reduction Program (TRRP) Rule at TAC §350.77(c)(2). It is recommended that the representative ecological receptors be selected that best evaluate the .bioaccumulative potential oflead. For example, avian and mammalian herbivores (mourning dove and rabbit) and invertivores (robin and shrew) should be evaluated, in addition to the carnivores that may feed on them. In addition, since animal burrows were observed on the site, an armadillo should be evaluated as a receptor. Also, the three identified rare species (or their surrogates) should be evaluated. 10. Section 5.1 Sediment to Surface Water PCL (as specified in the report however the correct terminology is the Soil to Sediment PCL): There are variables used in the equations presented in this section that do not have adequate references or explanations. For example, the value for the support practice factor (P) is specified as 0.08. However, no reference is given for where this number originated. In addition, the source for the acreage of the watershed was not identified. The TCEQ also requests information that identifies any areas located within the specified basin that have the potential to be _a _significant source oflead contamination (e.g., other shooting ranges). This information will assist the risk assessors in ensuring that the lead contribution from the basin is representative of existing conditions. Also, the Tier 2 Sediment PCL has a value (500 mg/kg) that is not referenced and it would seem that the more appropriate value is 82' mg/kg (the PCL for benthic invertebrates based on the midpoint of the initial and second effects levels for lead in freshwater sediment). It is necessary for all variables to be referenced/explained in order for the TCEQ to adequately assess the output values presented. This logic should be kept in mind in future submittals when variables that differ from those used in TCEQ guidance ( e.g., TRRP-24) are utilized. The addition of references and explanations helps to maintain transparency in calculations. 11. Tables 3.2, 4.1, 4.2, and 5.1 (and associated text): The soil depths at which the samples were obtained should be included in the tables. Texas Commission on Environmental Quality _J Bryan W.

Vickery, P.G., Executive Director TEXAS COMMISSION ON ENVIRONMENTAL QUALITY Protecting Texas by Reducing and Preventing Pollution February 18, 2011 Mr. Roger Grantham, Environmental Manager roger.grantham@fortworthgov.org City of Fort Worth 1000 Throckmorton Street Fort Worth,.Texas 76102 Re: Former Fort Worth Rifle and Pistol Club, 1950 Silver Creek Road, Fort Worth, Tarrant County, Texas; Voluntary Cleanup Program (VCP) No. 788; Customer No. CN600128862; Regulated Entity No. RN102071776 Dear Mr. Grantham: The VCP of the Texas Commission on Environmental Quality (TCEQ) has reviewed the September 15, 2010 report entitled Affected Property Assessment Report (APAR) and the December 15, 2010 Response Action Plan, prepared by Enercon Sevices. Please prepare a written response to each of the following comments referencing the assigned TCEQ comment number, unless otherwise specifically requested. The information in the TCEQ reference line above should be included in your response. Groundwater 1. As discussed in previous correspondence, the VCP agrees that groundwater is not currently impacted by chemicals of concern (COCs) above critical groundwater protective concentration levels (PCLs). Although the VCP is not currently requesting additional sampling, it is recommended that the monitoring wells continue to be maintained. · 2. As discussed in Section 3 of the APAR, target COCs initially included arsenic. The comment is made that post-remediation confirmation sampling identified lead as the remaining target COC. The VCP agrees that arsenic appears to be co- located with lead at the site. Elevated lead concentrations may be used as a screening tool; however, for the purposes of assessment, arsenic should not be eliminated as a COC, unless it can be screened out through the Texas Risk Reduction Program (TRRP) screening procedures. Where sources of arsenic exist ?ther than shot or bullet fragments, samples should still be analyzed for arsemc. P.O . Box 13087 Austin, Texas 78711-3087 512 -239-1000 Internet address: www.tceq .state.tx.us pr inted on recycled paper using soy~base d ink Mr. Roger Grantham Page2 February 18, 2011 VCPNo. 788 3. The VCP does not object to the use of XRF tool for screening level delineation; however, please note that confirmation and ultimate delineation samples should be analyzed using laboratory methods. 4. The December 20, 1996 report entitled Lake Worth Lease/Fort Worth Rifl.e and Pi.stol Club Lead Migration Investigation contains a ballistics evaluation for Range E only. It is not clear that such an analysis was conducted for Range SC. The results from the XRF analyses indicate that the extent oflead impacts has not been delineated. Please use a ballistics evaluation to direct additional assessment of the extent of lead impacts. Additionally, the 1996 report noted that shot from Range E had migrated into the intermittent stream bed to the east of the range. It is not clear that any foIIow-up inspections have been conducted. Please conduct another inspection of the intermittent stream · bed to determine if any shot has continued to migrate. · 5. In Table 4,A, the Tier 1 TotSoileomb PCL for lead based on residential exposure is correctly identified as 500 mg/kg. The owsoil PCL for lead is identified as 150 mg/kg, which is correct for a Class 3 groundwater resource. However, there are areas on the site where groundwater is considered . a Class 2 groundwater resource. The GWSoil PCL for lead in that case is 1.5 mg/kg. In either case, it is not clear where the human health PCL of 30 mg/kg was obtained in Table 4B. A qualitative statement is made in Section 2.6 that leaching of COCs in surface soils to groundwater (are) not considered complete pathways. If the City of Fort Worth wishes to calculate an alternate PCL, please note that TRRP affords the person the opportunity to calculate a PCL based on site specific parameters under Tier 2 or Tier 3. The City may also endeavor to substantiate an argument that a soil leachate to grormdwater PCL need not be established, pursuant to 30 Texas Administrative Code 350.75(i)(7)(C). 6. It is further noted that the Ecological PCLs have not been confirmed, as a response to the November 15, 2010 TCEQ Interoffice Memorandum (IOM) entitled Comments to Ecological Risk Assessment and Sediment Surface Water Protective Concentration Levels has not yet been received. Please provide a response to the comments in this IOM, referencing specific reports and tables in which the responsive data are contained. The VCP recommends that the critical PCL for lead in soils be determined prior to any additional response action. 7. The VCP does not generally object to the response actions proposed in the December 15, 2010 RAP; however, we wish to defer approval or additional comment until the remaining assessment issues are addressed, as discussed in Comment 6. · Mr. Roger Grantham Page3 February 18, 2011 VCPNo.788 A response to these comments should be submitted to my attention at the TCEQ at the letterhead address using mail code MC-221. Your response must be received on or before April 18, 2011. Should you need additional information or wish to discuss these comments or due date, please call me at (512)239-2960. fbAci!&- R.

SUMMARY OF THE WORK 1.1.1. CONTRACT DOCUMENTS AND RELATED REQUIREMENTS: General provisions of the contract , including general and supplementary condit ions , apply to the work of this section. The contract documents show the work of the contract and related re- quirements and conditions impacting the project. Related requirements and conditions include applicable codes and regulations , notices and permits , existing site conditions and restrictions on use of the site , requirements for partial owner occupancy during work , coord ination with other work and phasing of work. Whenever there is a conflict or overlap of the above refer- ences , the more stringent provis ions apply . 1.1.2. EXTENT OF WORK: A brief summary of the extent of the work and non-binding to the contract documents is as fol- lows : BASE BID: Removal and disposal of asbestos-containing materials (ACM) and asbestos-contaminated elements (ACE) utilizing wet methods within full , negative-pressure containments equipped with HEPA ventilat ion from specified areas of the buildings . The following asbestos-containing ma- terials (ACM) will be removed at the property where applicable . 5651 East Lancaster, Fort Worth, Texas Floor tile and mastic 4,880 square feet Library, kitchen , work area, office The Work Area will be inclusive of the locations and the quantities noted above , in the attached drawings , and as directed by a representative of IHST. The Work may be broken down into multiple Work Areas at the discretion of the Contractor. However, the Contractor will receive no additional time to perform the work on the basis of having multiple Work Areas and associated Cleaning Sequences. The Contractor will be respons ible for the removal and disposal of the asbestos-containing ma- terial and asbestos-contaminated materials in accordance with Texas Department of State Health Services (TDSHS), OSHA 29 CFR 1926.1101 , Asbestos Hazard Emergency Response Act (AHERA) 40 CFR Part 763 , and the National Emission Standards for Hazardous Air Pollut- ants (NESHAP) Regulations 40 CFR Part 61 . )/~I(· ~/.Jr DSHS License 10-5040 Expires 12-31-0911 Page 1 ASBESTOS REMOVAL The CONTRACTOR shall be responsible for verifying existing site conditions and determining the quantity of ACM delineated for removal prior to abatement described in these specifications and associated drawings. 1.1.3. TASKS: The work , located at the facility , is summarized briefly as follows : The PROJECT requires the removal of the materials outlined in Section 1.1.2 . The asbestos abatement will be performed in accordance with these specifications and procedures as out- lined. Power and Water Connections: The City will supply water and power for this project. Asbestos Removal within full Containment: The Contractor will use wet methods for all re- moval operations . The Contractor is responsible for prompt clean-up and disposal of waste and debris contaminated with asbestos in leak tight containers . The Contractor will conduct a wet decontamination of equipment and tools before final clearance sampling in the work area. The Contractor will use the existing interior walls and will have to build a false ceiling above the plaster lathe which will be removed to provide structural support for an asbestos containment work area provided the containment remains sound and is not in danger of collapse. The Con- tractor should make every effort not to damage the interior walls of the building during the pro- ject. The Contractor will establish critical barriers over all openings into the work area . ACM debris should be adequately wetted prior to establishing perimeter critical barriers The full containment design must be structurally sound so that it will not collapse under negative pressure and work conditions . A structurally unsound containment design will not be ac- cepted. The full containment design will consist of one (1) layer of 6-mil polyethylene sheeting for all critical barriers , floors and walls. Two layers of polyethylene sheeting will be required on walls and floors not affected by the abatement Polyethylene sheeting shall meet the requirements in accordance with current TDSHS rules . The Contractor must establish negative air into the containment and maintain a pressure differential of -0 .02 inches of water as indicated by a working manometer. After the ACM has been removed and the work area cleaned , a detailed visual clearance in- spection will be conducted to determine if ACM or asbestos-contaminated elements (ACE) re- main prior to final clearance and work completion . OSHA personnel and area monitoring will be conducted with analysis by (PCM). Final air clearance sampling will be conducted utilizing PCM. Before the containment can be removed, the area must be cleared per the mold protocol. Respiratory protection will require half-face , air-purifying respirators (APR) with NIOSH- approved P-100 (HEPA) cartridges during removal. )/~'<. ~/.i'fr" DSHS License 10-5040 Expires 12-31-11 Page 2 ASBESTOS REMOVAL The CONTRACTOR is responsible to verify site conditions and estimated quantities of ACM to be removed. 1.1.4. CONTRACTORS USE OF PREMISES: Cooperate fully with the Owner's Representative to minimize conflicts and to facilitate Owner's safe and smooth usage of buildings . Perform the work in accordance with specifications, draw- ings , and phasing plan. Use existing facilities in building strictly w ith i n the limits shown in contract documents and the approved pre-abatement plan of action. Several of the structures have asbestos containing ma- terials in the flashing around roof penetrations. The Contractor will not be required to remove the flashing on the structures. 1.2. DIFFERING SITE CONDITIONS: The quantities and location of ACM indicated on the drawings and the extent of work included in this section are only best estimates which can be limited by the physical constraints imposed by structural enclosures or by occupancy of the building. The CONTRACTOR is responsible to verify site conditions and estimated quantities of ACM to be removed and determining the quantity of ACM delineated for removal prior to abatement described in these specifi- cations and associated drawings. The Contractor by placing a bid for this project agrees with all quantity estimates and there bid reflects there price to remove all of the material at all of the structures as identified in these specifications. 1.3. STOP ASBESTOS REMOVAL: If the Owner's Representative presents a written Stop Asbestos Removal Order, immediately stop all asbestos removal and initiate fiber reduction activities. Do not resume asbestos removal until authorized in writing by Owner's Representative. A Stop Asbestos Removal Order will be issued at any time the Owner or Owner's Representative determines abatement conditions are not within specifications requirements. Stoppage will continue until conditions have been corrected. Standby time and cost required for corrective action is at Contractor's expense. The occurrence of the following events will be re- ported in writing to the Owner's Representative and will require the Contractor to automatically stop asbestos removal and initiate fiber reduction activities: A. Excessive airborne fibers outside containment area (0 .01 flee or greater). B . Break in containment barriers . C. Loss of negative air pressure (at or above 0.01 inches of water) D. Serious injury within the containment area. E. Fire and safety emergency F. Respiratory system failure . G. Power failure . H. Excessive airborne fibers inside containment area (0 .1 flee or greater when wet methods are employed). Page 3 ASBESTOS REMOVAL 1.4. CODES AND REGULATIONS: 1.4.1.

GENERAL: Provide respiratory protection in accordance with these specifications , the OSHA regulations 29 CFR 1910 .1001 , 29 CFR 1910.134 and 29 CFR 1926 .1101 , EPA regulations 40 CFR 763.120 , 121 , ANSI standards 288 .2-1980 , CGS Pamphlet G-7 and specification G-7 .1, the NIOSH and MSHA standards and the Texas Department of State Health Services Protection Rules. In case of conflict , the most stringent requirements are applicable for this project. Page 5 ASBESTOS REMOVAL 1.6.2. RESPIRATORS FOR ABATEMENT OPERATIONS: Where a person is or could reasonably be expected to be exposed during abatement operations to airborne asbestos above 0.1 flee or where ACM debris is visible , the following maximum level of respiratory protection is requi red: If it is reasonably anticipated that fiber counts generated during abatement will not exceed the protection factor of a half-face respirator , and this can be verified by on-site fiber counts , a half-face respirator may be used. If verification cannot be made , a full face PAPR must be used . PAPR must be used for friable surfac- ing or thermal system insulation removal until fibe r counts are confirmed cons is- tently below the PEL and STEL . Head coverings : PAPR respirators will be equipped with full facepieces. Full facepieces will be worn with either a bonnet-type disposable head cover/hood or with a full head cover/hood which is part of a fully encapsulating protective garment. Respirator straps will be located under the hoods . This allows removal of the head covering prior to showering without disturbing the respi- rator (which is worn into the shower). Exemptions from maximum respiratory protection during abatement operations : When the abatement contractor has demonstrated to the Owner's satisfaction that levels of airborne as- bestos fibers in the work area are consistently below 0 .1 flee , a full facepiece or half face respi- rator with HEPA cartridges may be used . The Certified Industrial Hygienist will determine if a lesser form of respiratory protection may be used . 1.7. WORKER PROTECTION: 1.7.1. TRAINING PRIOR TO ENGAGING IN ABATEMENT WORK: Train workers in accordance with OSHA 29 CFR 1926.1101 and the Texas Asbestos Health Protection Rules and this section . Workers will be trained and be knowledgeable on the follow- ing topics : Methods of recognizing ACM ; health effects of asbestos exposure ; effects of smok- ing and asbestos exposure ; activities that could result in hazardous exposures ; protective con- trols , practices and procedures to minimize exposure including engineering controls , work prac- tices , respirators , housekeeping procedures , hygiene facilities , protective clothing , decontamina- tion procedures , emergency procedures and waste transportation and disposal ; review OSHA 29 CFR 1910.134 for respirators ; medical surveillance program ; review OSHA 29 CFR 1926 .1101 , and for air monitoring , personnel and area ; review this section of the project specifi- cations . 1. 7.2.

Provide adequately sized DF to accommodate the number of employees scheduled for the project. The center chamber of the three chamber DF will be fitted with as many portable walk through shower stalls as necessary so that all employees will be able to go through the en- tire decontamination procedure within 15 minutes. Construct DF of opaque or colored polyethyl- ene for privacy. Construct DF so that it will not allow for parallel routes of exit without shower- ing. 1.9. NEGATIVE PRESSURE FILTRATION SYSTEMS: The Asbestos Abatement Contractor will provide enough HEPA-filtered negative air units to completely exchange the work air four (4) times per hour. Contractor will demonstrate the num- ber of units needed per work area for 4 room air changes by calculating the volume flow rate (cfm) delivered by each unit under 2" pressure drop across filters . Provide at least one standby unit in the event of a machine failure or emergency such as contamination in surrounding non- work area. When a pressure differential system is selected provide enough HEPA filtration units to filter and recirculate the air in the work area at a rate of four (4) room air changes per hour. 1.9.2. PRESSURE DIFFERENTIAL: Provide a fully operational negative air system within the work area continuously maintaining a pressure differential across work area enclosures of -0.02 inches of water. Demonstrate to the Owner's Representative the pressure differential by use of a pressure differential meter or a manometer, before disturbance of any asbestos containing materials. This pressure differential will be used for either negative air system or pressure differential system. 1.9.3. MONITORING: Continuously monitor and record the pressure differential between the work area and the build- ing outside of the work area with a monitoring device incorporating a strip chart recorder. Make the strip chart record part of the project log. Page 9 ASBESTOS REMOVAL 1.9.4. TESTING THE SYSTEM: Test negative-pressure system before any ACM is wetted or removed. After the work area has been prepared , the decontamination fac i lity set up , and the exhaust unit(s) installed , start the unit(s) (one at a time). Demonstrate operation and testing of negative-pressure system to the Owner's Representative. 1.9.5. DEMONSTRATION OF NEGATIVE AIR SYSTEM OPERATION: Demonstrate the operation of the negative-pressure system to the Owner's Representative to include , but not be limited to , the following : 1. Demonstrate pressure differential system will maintain -0.02" of water. 2. Emergency shutoff will operate in case of fire . 1.9.6. USE OF SYSTEM DURING ABATEMENT OPERATIONS: Start exhaust units before beginning work (before any ACM is disturbed). After abatement work has begun , run units continuously to maintain a constant negat ive-pressure until decontamina- tion of the work area is complete . Do not turn off units at the end of the work shift or when abatement operat ions temporarily stop . Do not shut down negative air system during abatement operations procedures , unless author- ized by the Owner's Representative in writing . The systems may be shut down daily if air moni- toring in the containment shows airborne levels of less than 0 .01 fibers/cc . Start abatement work at a location farthest from the exhaust units and proceed toward them. If an electric power failure occurs , immediately stop all removal work and do not resume until power is restored and all exhaust units are operating again. At completion of abatement work , allow exhaust units to run as specified under this section , to remove airborne fibers that may have been generated during abatement work and cleanup and to purge the work area with clean makeup air. Units may be required to run after decontamina- tion , if dry or only partially wetted asbestos material was encountered during any abatement work . 1.9.7. DISMANTLING THE SYSTEM: When a final inspection and the results of the final air tests indicate that the area has been de- contaminated , exhaust units may be removed from the work area. Before removal from the work area , remove and properly dispose of pre-filters , and seal intake to the machine with 6-mil polyethylene to prevent environmental contamination from the pre-filters. 1.10. CONTAINMENT BARRIERS AND COVERINGS OF WORK AREA: 1.10.1. GENERAL: Sea l off perimeter of work area to completely isolate abatement areas and to contain all air- borne asbestos contamination created by abatement work. Cover all surfaces of the work area to protect them from cross contamination , to facilitate more efficient cleanup , and to protect the finishes from the asbestos abatement work. Should the area beyond the seal off limits become Page 10 ASBESTOS REMOVAL contaminated as a consequence of the work , clean those areas in accordance with procedures described in this section at no additional cost. 1.10.2. PREPARATION PRIOR TO SEALING OFF: Place all tools , staging, etc . necessary for the work in the area to be isolated prior to erection of temporary plastic sheeting enclosure. Disable ventilating systems or any other system bringing air into or out of the work area. Disable system utilizing positive means that will prevent acci- dental premature restarting of equipment, i.e ., disconnecting wires , removing circuit breakers , lockable switch , etc. 1.10.3. CONTROL ACCESS TO WORK AREA: Permit access to the work area only through the OF. All other means of access will be closed off and sealed and warning signs displayed on the clean side of the sealed access . Where the work area is immediately adjacent to or within view of occupied areas , provide a visual barrier of opaque polyethylene sheeting at least 6-mil in thickness so that the work procedures are not visible to building occupants . Where the area adjacent to the work area is accessible to the public, construct a barrier of plywood or other suitable material at least eight feet (8 ') in height that is able to withstand the negative pressure as specified. Post warning signs at each visual and physical barrier per OSHA requirements . Alternate method of containing the work area or different definition of the limits of seal-off from the one shown on the drawings may be submitted to the Owner's Representative for approval in accor- dance with this section. Do not proceed with any such alternatives without prior written approval by the Owner's. 1.10.4. CRITICAL BARRIERS: Completely separate the work area from other portions of the building , and the outside by sheet polyethylene barriers at least 6 mil in thickness and sealing with duct tape . Individually seal all ventilation openings (supply and exhaust), lighting fixtures, doorways, windows , and other open- ings into the work area with duct tape alone and with polyethylene sheeting at least 6-mil in thickness , taped securely in place with duct tape. Maintain seal until all work including project decontamination is completed. Take care in sealing off lighting fixtures to avoid melting or burn- ing of sheeting . Provide sheet plastic barriers at least 6-mil in thickness as required to com- pletely seal openings from the work area into adjacent areas . Seal the perimeter of all sheet plastic barriers w ith duct tape or spray cement. 1.10.5. PRIMARY BARRIERS: The primary barrier of the full containment walls will consist of a minimum of Primary barriers for full containment shall consist of two (2) layers of minimum 4-mil polyethylene sheeting for the walls securely anchored from the floors to the ceiling . The containment for the removal of the li- noleum flooring will require a minimum 4-mil polyethylene sheeting for the ceiling . Polyethylene sheeting shall meet ASTM requirements in accordance with TDSHS regulations . Visible open- ings observed along the perimeter walls and the ceiling shall be completely sealed polyethylene sheeting and the wall corners of the containment should be attached with an overlap of at least twelve inches . The primary barrier construction should form an airtight, impermeable , perma- nent barrier around the ACM and ACM debris to contain the release of asbestos fibers into the air . Page 11 ASBESTOS REMOVAL 1.10.6. EXTENSION OF WORK AREA: If the enclosure barrier is breached in any manner that could allow the passage of asbestos de- bris or airborne fibers , then where possible , add affected area to the work area . Enclose it as required by this Section of the specification and decontaminate it as described elsewhere in this section . If contaminated area cannot be added to work area , decontamination measures w ill start immediately after contamination is discovered and work will stop in work area. Decontami- nation procedures will continue until exposure returns to background levels . 1.10.7. SECONDARY BARRIERS: Secondary barriers should be established in areas to separate any non-related work activity from the abatement conta inment to prevent dust or debris from potentially contaminating fresh air (make-up air) into the containment or regulated asbestos removal area . 1.11. MONITORING, INSPECTION AND TESTING: 1.11 .1. GENERAL: Perform throughout abatement work monitoring , inspection and testing inside the work area in accordance with OSHA requirements and these specifications . I.H. Technician will continuously inspect and monitor conditions inside the work area to ensure compliance with these specifica- tions . In addition , the I.H . will personally manage air sample collection , analysis and evaluation for personnel and work area samples to satisfy OSHA requirements. Additional inspection and testing requirements are specified in other parts of this section. The Owner will employ a Certified Industrial Hygienist (C.1.H .) representative to perform various services on behalf of the Owner. The C.I.H. representative or representative under the direction of a C .I.H. will perform the necessary monitoring , inspection , testing and other support services to ensure that the Owner, employees and visitors will not be adversely impacted by the abate- ment worked , and that the abatement work proceeds in accordance with these specifications , that the abated areas or abated buildings have been successfully decontaminated . The work of the C.I.H. representative in no way relieves the abatement Contractor from his responsibility to perform his work in accordance with contract documents , to perform continuous inspection , monitoring and testing for the safety of his employees , and to perform other such services as specified in this section . The cost of the CIH representative and his services will be born by the Owner except for repeated final inspection and testing that may be required due to unsatisfac- tory initial results. These repeated final inspections and test ing , if required , will be paid for by the Contractor. The Asbestos Abatement Cont ractor may request confirmation of above results. This request must be in writing and submitted to the Owner's Representative . Cost for the confirmation of re- sults will be born by the Contractor for both the collection and analysis of samples and for the time delay that may result for this confirmation . Confirmation sampling and analysis will be the responsibility of the Contractor with review and approval by the C.I.H. Page 12 ASBESTOS REMOVAL 1.11.2. OUTLINE SCOPE OF SERVICES OF THE OWNER'S CONSULTANT: The purpose of the work of the Owner's Representative is to : assure quality , resolve problems, and prevent the spread of contamination beyond the work area .

TASK 6: Issue certificate of decontamination for each area or building and a final project report . TASK 7: The Owner's Representative will have authority to require building materials to be removed and disposed of as ACM waste where visible ACM debris is pre- sent. All data, inspection results and testing results generated by the Owner's Representative will be available to the Contractor for information and consideration . Contractor will provide coopera- tion and support to the Owner's Representative for efficient and smooth performance of their work. Monitoring and inspection results of the Owner's Representative will be used by the Owner to issue any Stop Asbestos Removal Orders to the contractor during abatement work and to ac- cept or reject an area or a building as decontaminated. The Owner's Representative will make available to the Contractor the plan for sample collection and analysis for continuous monitoring outside the work areas and the plan of final inspection and testing for each space or building prior to executing each plan. Plan will include location for samples , name and qualification of person tak ing samples, whether on site analysis and/or lab analysis will be utilized , methodol- ogy of analysis, lab information and qualifications of on-site analyst. 1.11.3. MONITORING, INSPECTION AND TESTING BY ABATEMENT CONTRACTOR: The Contractor is responsible for managing all monitoring , inspection and testing required by these specifications and the OSHA requirements. Page 13 ASBESTOS REMOVAL The analytical laboratory that will be used by the Contractor to analyze the samples will be AIHA P.A.T. Accredited and Texas Department of State Health Services Licensed. Keep a daily log of personnel samples taken and analyzed and make log available to the Owner's Representa- tive. Log w i ll contain information on the persons sampled , the date of sample collection the time of sa mple start and finish , flow rate , sample volume and fibers/cc. Take and analyze personnel samples for at least 25% of the worke rs in each shift , but not less than two where active abate- ment takes place. 1.11.4. ANALYSIS: Bulk samples (if required) will be analyzed at a laboratory that is Accredited by the Nat ional Vol- untary Laboratory Accreditation Program (NVLAP). Proof of accreditation must be submitted prior to the project start date . Polarized light microscopy will be used to analyze bulk samples . Air samples will be analyzed by an individual participating in the American Industrial Hygiene Association's (AIHA) Proficiency Ana lytical Testing Program . In addition to the continuous monitoring required , the Owner's Representative will perform in- spection and testing at the final stages of abatement for each work area or building as specified elsewhere in this section . 1.12.5.

The project report will include a certificate of completion , dated and signed by the Contractor. All certificates and original disposal manifests are due to the Owner's Representative office within 30 (thirty) days after completion of abatement work. PART 2 -EXECUTION 2.1. PREABATEMENT ACTIVITIES: 2.1.1. PREABA TEMENT MEETING: The Owner's Representative , upon receipt , review and substantial approval of all preabatement submittals and upon verification that all material and equipment required for the proj ect are on site , will arrange for a preabatement meeting between the Asbestos Abatement Contractor , su- perintendent and foremen and the Owner's Representatives. The purpose of the meeting is discuss any aspects of the submittals needing clarification or amplification and to d iscuss any aspects of the project execution and the sequence of operations. The Asbestos Abatement Contractor and his employees w i ll be prepared to provide any sup- plemental evidence and information to the Owner's Representative pertaining to any aspects of the submittals or the materials and equipment. No abatement work of any kind described in the following provisions of these specifications will be initiated prior to the preabatement meeting. 2.1.2. PREABA TEMENT INSPECTION AND PREPARATIONS: Befo re any work begins on the containment barriers , the contractor will : 1. Conduct a space-by-space inspection with an authorized Owner's Representative , and prepare a written inventory of all existing damage in those spaces where asbestos re- Page 14 ASBESTOS REMOVAL moval work w ill occur. Still or video photography may be used to supplement this written damage inventory . Documents will be signed and certified as accurate by both parties. 2. Ensure that all furniture , machinery , equipment , curtains drapes , blinds and other mov- able objects which the contractor is bound to remove from the work area have been re- moved or protected. 3. Notify the Owner's Representative of systems that need to be shut down as soon as practical in advance . The Owner's Representative will coordinate shutdown with Con- tractor and Owner's Facility Representative . The Owner's Facility Representative will perform and monitor shutdown as required by Contractor. a. Shutdown and seal off all heating , cooling , ventilating or other air handling systems serving the work area . The environment of the work area will be completely isolated from all other air flows in the building . Owner's Representative will monitor shut- down . b. Shut down all electrical circuits which pose a potential hazard on the job. Exact elec- trical arrangements will be tailored to the particular space and systems involved . All electrical circuits will be turned off at the box outside the removal area , not just the wall switch. Potential for electrical shock is a major threat to life in a work area where large amounts of water will be sprayed on ceilings , conduits , lighting fixtures and other electrical items . Electrical lines which are used to power work lights and equipment will conform to all electrical safety standards and will be protected by a ground fault interrupter. The Asbestos Abatement Contractor will be responsible for all OSHA lockout/tagout requirements . A copy of the Asbest os Abatement Contrac- tor's lockout/tagout program must be submitted for review prior to asbestos abate- ment operations. 2.1.3. PREABA TEMENT CONSTRUCTION AND OPERATIONS: Perform all preparatory work for the first work area in accordance with the approved detailed work schedule. Execute the preparatory work in accordance with th is specification . Upon completion of all preparatory work , the Owner's Representative will inspect the work and systems to assure work is in accordance with these Specifications . The Owner's Representa- tive may require that , upon satisfactory inspection , the Contractor's employees perform all major aspects of the approved SOP especially on worker protection , respiratory protection , contin- gency plans , decontamination procedures and monitoring to demonstrate satisfactory operation . The operating systems for respiratory protection and negative pressu re air systems will be demonstrated for performance. Upon satisfactory inspection of the installation and systems and satisfactory demonstration of operations the Owner's Representative will notify the Contractor to proceed with abatement work. 2.2. REMOVAL OF ACM AND ACE: 2.2.1. WETTING MATERIALS: The Asbestos Abatement Cont ractor will adequately wet and remove all ACM as follows : 1. Spray wetting agent on the asbestos containing materials. Page 15 ASBESTOS REMOVAL 2 . After wetting and removal, seal all ACM waste in leaktight two layers of 6-mil polyethyl- ene while wet. For waste material not fitting into containers without additional breaking, put material into leaktight wrapping. 3. Label containers and wrapped material using warning labels as specified by OSHA 29 CFR 1910.1001 or 1926.1101 and the NESHAPS regulations . 4 . For ACM being transported off the facility site , label ACM waste containers and wrapped material with the name of the waste generator and the location where the waste was generated . 2.2.2. SITE PREPARATION: Erect critical barriers at all doors and windows entering the regulated areas. This project will be conducted by establishing critical barriers over all openings into the work area. A three stage wet decontamination unit will be erected for worker entrance and exit into the work area . The Contractor must establish negative air in the containment and maintain a pressure differential of -0 .02 inches of water column pressure differential. 2.2.3. PERSONAL PROTECTION: One (1) layer of disposable clothing air-purifying respirators (PAPR) with NIOSH-approved HEPA cartridges shall be worn by all personnel during removal of the asbestos-containing ther- mal system insulation. Provide boots, safety glasses and gloves for all workers. Equipment will meet OSHA require- ments for personal protection. Provide all persons entering the work area with disposable full body coveralls, disposable head covers and rubber boots. 2.2.4. THERMAL SYSTEM INSULATION: The Contractor may remove the pipe insulation and elbows in a full containment or use a glove bag. If a glovebag is usued the procedures listed below will be used: The minimum crew size for a glovebag operation is two: one member performs the actual re- moval with "hands in the gloves" and the second directs the spray wand at the work . It is rec- ommended that three people be used. The third helps support the bag , makes sure tools and supplies are readily available, and is on hand in case of emergency . All crew members should be trained in the use of the glovebag. The Contractor will erect critical barriers and establish negative air filtration. Rope off work area and place warning signs. Bring the necessary materials into the work area. Have a HEPA vac- uum system available at all times . The HEPA vacuum will be used to establish negative air fil- tration inside of the glove bag . Make sure that possible contaminants in the area have been cleaned with the proper methods before beginning the glovebag procedure to avoid confusion concerning the source of the mate- rial. Wrap the adjacent pipe not to be enclosed in the glovebag with 6-mil plastic . Cover surfaces , such as the floor and walls, near the glovebag removal site with 6-mil plastic. Page 16 ASBESTOS REMOVAL Disposable clothing and full-face PAPR respirators will be worn be any person performing glovebag removal. If fiber counts generated during abatement do not exceed the protection fac- tor of a half-face respirator during glovebag removal of TSI , and this can be verified by on-site PCM fiber counts, a half-face respirator may be used. Wrap duct tape around the insulation where the shoulders of the glovebag will be attached . Put the necessary tools in the pouch of the glovebag . Slit the glovebag as necessary to fit it over the pipe from which insulation is to be removed . Attach the glovebag to the previously applied duct tape at the shoulders . Fold the top edge of the bag between shoulders over on itself about an inch , then staple it about every two inches . Fold it again and tape the folded edge to the bag. Seal all joints with duct tape. Prepare the opening for the spray wand. If the manufactured location is not accessible , be sure to reinforce the bag with duct tape where the slit is to be made . Slit must be covered with rub- ber septum-like material that will seal after the wand is removed . Be sure the sprayer and bag are properly supported . The glovebag will have to have a smoke test to assure that the bag is sealed . Assemble the tube and bulb . Insert the tube into the slit prepared for the spray wand . Fill the bag with smoke and gently squeeze. Watch for leaks particularly at seams, joints , corners , and arms . Seal leaks with duct tape. Establish negative air filtration of the glovebag before any removal operations take place . Wet the covering of the insulation , keeping it wet through the entire operation . Remove any metal covering with the tin snips. Remove the outer covering of the insulation. This may expose wire that needs to be cut before proceeding . Be sure that sharp edges of metal and wire are folded inward to avoid puncturing the bag . It may be possible to further pro- tect the bag by packing insulation , which has already been removed from the pipe and placed at the bottom of the bag , around sharp edged material. Remove the insulation . If possible , remove sections as they were installed. Otherwise use the utility knife and/or the flex saw to cut out the section which is then pried off. Keep the insulation (especially newly exposed surfaces) wet during the procedure . As pieces of insulation are removed , lower them carefully to the bottom of the bag . Using the putty knife and the screwdriver, scrape any remaining res idue from the pipe . Rinse the pipe while scraping . Clean the pipe with the scrub brush. Wipe all cleaned surfaces with a wet rag and put the rag in the bottom of the bag . Rinse and wipe the inside of the glovebag. Rinse and wipe the tools , then put them in the pouch . Develop a check list to inventory tools in the glovebag. Page 17 ASBESTOS REMOVAL Pull one arm out of the glovebag, inverting the glove in the process . With the other hand , place tools in the inverted glove. Grasp the remaining tools and place them in the other glove as the second arm is withdrawn. After the bag has been collapsed and the bottom twisted off, twist the gloves between the tool and the glovebag and wrap with tape for about four inches starting at the bag . Leave a tab and cut through the tape. Either transfer the glove to a new bag (if work is to continue) or open the bag under water and remove the tools , making sure they are free from debris . Remove the spray wand and insert the nozzle of the HEPA vacuum in the slit. Turn the vacuum on and run it long enough to collapse the bag. Twist the bag and wrap it with duct tape just below the gloves and remove the HEPA vacuum nozzle. Glovebags may only be used once and may not be moved . When the bag is finally to be removed from the pipe , fold the dirty side inward and put it in a 6- mil disposal bag . Seal the disposal bag . Inspect the sections of the pipe where the insulation has been removed . Remove any remain- ing material with a wet rag or the HEPA vacuum . Apply a coat of sealant to the pipe. Clean up any debris or water on the floor with wet rags and/or the HEPA vacuum. As in any asbestos related project , the work area should be kept free of debris. Any contamina- tion should be cleaned up immed iately. When the work day is complete, (or as soon as the pro- ject is complete) the work area should be cleaned using wet methods and/or a HEPA vacuum . All glovebags should be removed from the pipes at the end of the work day (or as soon as the procedures are completed) and placed in double layer 6-mil asbestos disposal bags . Dispose of waste in accordance with regulations for asbestos waste found in these specifications . Workers should pass through a complete decontamination facility when exiting the work area . If the bag develops a leak , stop work inside the bag . Catch the water in a plastic disposal bag. Lift and move the bag so that water stops running out. Do not "pump" the bag in a way that would force air out. Twist the bag in the area of the puncture to form a stem , dry the surface and tape it securely closed. Clean up the contaminated water and debris from the floor immedi- ately using wet methods and/or the HEPA vacuum . Dispose of the waste properly. Alternate removal techn iques may be used if approved by the CIH. 2.2.5. FLOOR TILE AND MASTIC: Those areas normally exposed to heavy foot t raffic patterns usually have tiles adhered the tight- est. As a matter of good practice in starting the tile removal , those sections wh ich receive the least traffic should be the locations selected for starting the removal of the tile. Since tiles are Page 18 ASBESTOS REMOVAL normally in a 9" x 9" or 12" x 12" dimension , it should be the goal to remove individual tiles as a complete unit to the best extent possible . Start the removal by carefully wedging the wall scraper in the seam of two adjoining tiles and gradually forcing the edge of one of the tiles up and away from the floor . Do not break off pieces of the tile but continue to force the balance of the tile up by working the scraper beneath the tile and exerting both a forward pressure and a twisting action on the blade to promote re- lease of the tile from the adhesive and the floor. When the first tile is removed , place it , without breaking into smaller pieces , in the heavy-duty impermeable waste bag or closed impermeable container which will be used for disposal. With the removal of the first tile accessibility of the other tiles is improved. Force the wall scraper under the exposed edge of another tile and continue to exert a prying twisting force to the scraper as it is moved under the tile until the tile released from the floor. Again , dispose of the tile, and succeeding tiles, by placing in the heavy-duty bag or closed container without additional breaking . Some tiles will release quite easily while others require varying degrees of force . Where the adhesive is spread heavily or is quite hard , it may prove easier to force the scraper through the tightly adhered areas by striking the scraper handle with a hammer using blows of moderate force while maintaining the scraper at a 25° to 30° angle to the floor. Caution: Use safety gog- gles. If some areas are encountered where even the technique detailed in the previous paragraph proves to be inadequate , the removal procedure can be simplified by thoroughly heating the tile(s) with a hot air blower until the heat penetrates through the tile and softens the adhesive. Note 1: Handle the hot air blower , tiles , and adhesive carefully to avoid personal burns. Note 2: Do not handle the heated tiles and adhesive without suitable glove protection for the hands. As small areas of subfloor are cleared of tile , the adhesive remaining on the floor must be scraped up with the 4" hand scraper until only a thin , smooth film remains . In those area where deposits are heavy or difficult to scrape, the removal can be expedited by heating with the hot air blower prior to scraping. Deposit scrapings in a heavy-duty impermeable trash bag or closed impermeable container. Thoroughly spread approved mastic biodegradable cleaner/solvent onto all mastic with a garden sprayer (Note The solvent used to remove the mastic must have a flash point of >140 degrees F. Submittals for the solvent must include a Material Safety Data Sheet. Let the solution stand for at least 15 minutes. Use an industrial buffer with coarse pads to dislodge the material or a squeegee. Squeegee, or use scrapers to push material into a cen- tral location for final mopping and cleanup . Hand-scraping may be done at the Contractor's op- tion , or as required to completely remove all material. As indicated in previous paragraphs , tiles should be placed immediately in a waste disposal bags or closed impermeable container. Do not attempt to break tiles after they are in the bag. Page 19 ASBESTOS REMOVAL When all tiles , mastic and sorbent material have been removed from the floor and placed in polyethylene waste bags at least 6-mil thick or closed containers , seal the bags securely for dis- posal. "Shot blaster" or "bead blaster" machines will not be allowed to remove the floor tile and mastic. Alternate removal techniques may be used if approved by the CIH . 2.2.6 WALL AND CEILING TEXTURE AND The asbestos texture will be kept wet and removed by wet scraping or as intact sheetrock and ceiling tile sections utilizing hand tools and a low water volume , short distance power diffusing "Airless" sprayer . The asbestos plaster texture and texture on CMU block will be kept wet and removed utilizing hand tools and a low water volume , short distance power diffusing "Airless" sprayer. The minimum crew size for the operation is three : one member performs the actual removal , the second directs the spray wand at the work and the third worker collects and contains the wet ACM debris generated during the work. It is recommended that four workers be utilized in the procedure . The fourth person provides support during the work , making sure tools and supplies are readily available , and is on hand in case of emergency . All crew members should be trained in the use of the wet scraping procedure . The Contractor will erect critical barriers and establish negative air filtration . Rope off work area and place warning signs. Bring the necessary materials into the work area. Have a HEPA vac- uum system available at all times. The HEPA vacuum will be used to remove debris which may settle in remote areas such as corners , cracks or crevices in the work area . Make sure visible ACM debris and dust in the area have been wetted with amended water and cleaned with the proper methods before beginning the procedure to avoid confusion concerning the source of the material. Cover floor with a minimum of two layers of 6 mil plastic sheeting if flooring is not being re- moved , and cover wall surfaces with a minimum of two layers of 4 mil plastic sheeting . The top polyethylene sheeting layer may be removed as part of the detail cleaning process after gross removal. Hard hats , disposable clothing and full-face PAPR respirators will be worn by all persons per- forming the ACM removal. Establish negative air filtration in the containment before any removal operations take place . The containment may be smoke tested to assure the negative pressure inside the containment is adequately sealed . Assemble the smoke tube and bulb. Generate short bursts of smoke in the containment particularly at seams , joints and corners and critical barriers. Observe the direc- tion of the smoke trail. Watch for leaks, and seal any leaks with duct tape . Wet the plaster and surfacing material adequately to suppress any generation of airborne dust or debris , keeping it wet throughout the entire operation . Page 20 ASBESTOS REMOVAL As sections of ACM are removed , keep the material wet and shovel debris carefully into the bot- tom of a disposal bag. Wipe all cleaned surfaces with a wet rag and put the rag in the bottom of a 6 mil disposal bag. Rinse and wipe the inside of the disposal bag . Clean up any debris or water on the floor with wet rags and/or the HEPA vacuum. As in any asbestos related project, the work area should be kept free of debris . Any contamina- tion should be cleaned up immediately. When the work day is complete, (or as soon as the pro- ject is complete) the work area should be cleaned using wet methods and a HEPA vacuum . All asbestos material and associated debris should be removed and placed in double layer 6 mil asbestos disposal bags before the end of the work day . Dispose of waste in accordance with regulations for asbestos waste found in these specifications. Workers should pass through a complete three-stage wet decontamination facility prior to exit- ing the building . If a disposal bag develops a leak, stop work inside the containment. Catch the water in a plastic disposal bag . Lift and move the bag so that water stops running out. Do not "pump" the bag in a way that would force air out. Twist the bag in the area of the puncture to form a stem, dry the surface and tape it securely closed. Clean up the contaminated water and debris from the floor immediately using wet methods and the HEPA vacuum . Dispose of the waste properly. 2.3. DISPOSAL OF ACM AND ACE WASTE MATERIAL: 2.3.1. GENERAL: The Asbestos Abatement Contractor will dispose of friable ACM and debris which is packaged in accordance with these specifications at the approved landfill.

PRE-DECONTAMINATION CONDITIONS: Before decontamination work starts, all ACM and ACE will be removed from the work area and disposed of along with any gross debris generated by the work . At the start of work for decontamination , the following will be in place : 1 Critical barrier which forms the sole barrier between the work area and other portions of the building or the outside. 2. Critical barrier sheeting over lighting fixtures , ventilation openings , doorways , convectors , speakers and other openings. 3. Decontamination facilities for personnel and equipment in operating condition and nega- tive pressure system in operation. Page 22 ASBESTOS REMOVAL 2.4.5. FIRST CLEANING: The Asbestos Abatement Contractor will carry out a first cleaning of all surfaces of the work area including items of remaining sheeting , tools , scaffolding and/or staging by use of damp- cleaning and mopping , and a HEPA filtered vacuum . Do not perform dry dusting or dry sweep- ing . Use each surface of a cleaning cloth one time only and then dispose of as contaminated waste. Continue this cleaning until there is no visible debris from removed materials or residue on plast ic sheeting or other surfaces. Remove all filters in air handling system(s) and dispose of as asbestos containing waste in accordance with requirements of these specifications . 2.4.6. SECOND CLEANING: If the Asbestos Project Manager is not satisfied with the first cleaning , the Contractor w ill per- form a second cleaning inside containment. If the containment fails to pass final air clearance criteria , the Contractor will perform additional wet cleaning inside containment. 2.4 .7. PRE-CLEARANCE INSPECTION AND TESTING: The Owner's Representative will perform a thorough and detailed visual inspection at the end of the second cleaning to determ ine whether there are any signs of v isible ACM or dust in the work area. If the visual inspection is satisfactory , the Contractor will then encapsulate all surfaces in- side the containment. Final air clearance will be performed in accordance with these Specifica- tions. 2.4.8. LOCK-BACK ENCAPSULATION: With the express permission of the Owner's Representative , the Asbestos Abatement Contrac- tor will perform a lock-back encapsulation of all surfaces from which ACM was removed . Exe- cute in accordance with provisions specified elsewhere and performance requirements as speci- fied in Paragraph 2 .2 .2 of this Specification .

FINAL TESTING: After a satisfactory final visual inspection and encapsulation , The Owner's Representative , will undertake the final testing . Air samples will be taken and analyzed in accordance with the pro- cedures for PCM specified elsewhere in this section. If release criteria are not met , the con- tractor w ill repeat final cleaning and continue decontamination procedure from that point. Addi- tional inspection and testing will be at the expense of the Contractor. If results of PCM a ir samples are satisfactory , remove the critica l barriers and shut down and remove HEPA un its as specified under Abatement Closeout. Any small quantities of residue material found upon removal of the plastic sheeting will be removed with a HEPA fi ltered vac- Page 23 ASBESTOS REMOVAL uum cleaner and localized isolation. If significant quantities , as determined by the Owner's Consultant, are found then the entire area affected will be decontaminated as specified herein for the Final Cleaning. If release criteria are met the Contractor will perform the abatement closeout and issue the cer- tificate of compliance in accordance with these specifications. 2.5.3. FINAL TESTING PROCEDURES: CONTRACTORS RELEASE CRITERIA: Work in an area is complete when the work area is visually clean and airborne fiber levels have been reduced to less than 0 .01 fibers/cc by PCM analysis. AIR MONITORING AND FINAL CLEARANCE SAMPLING: To determine if the elevated air- borne fiber counts encountered during abatement operations have been reduced to the speci- fied level, the Owner's representative will secure samples and analyze them according to the following procedures: 1. Fibers Counted : "Fibers" referred to in this section will be either all fibers regardless of composition as counted in the NIOSH 7400 method , or asbestos fibers of any size as counted using PCM; and 2.5.4. SCHEDULE OF AIR SAMPLES WITH PCM: The Owner's Consultant will perform background, perimeter and work area samples during con- struction and abatement. These samples will be analyzed by PCM . At least three (3) background samples will be taken before work begins for a baseline meas- urement. The Owner's Representative will sample at a rate of one sample per 1,000 sq . ft . of work area with a minimum of two area samples for small containment areas . A minimum of 1,250 liters of air will be collected for all baseline and clearance samples. From start of actual removal of asbestos-containing materials the Owner will take the following samples on a daily basis.
