This specification will establish procedures to be used by ail Excavators in the removal and disposal of ACP in compliance with NESHAP. Nothing in this specification shall be construed to void any provision of a contract or other law, ordinance, regulation or policy whose requirements are more stringent. B. ACP is defined under NESHAP as a Category Il, non-friable material in its intact state but which may become friable upon removal, demolition and/or disposal. Consequently, if the removal/ disposal process renders the ACP friable, it is regulated under the disposal requirements of 40 CFR 61.150. A NESHAP notification must be filed with the Texas Department of Health. The notification must be filed at least ten days prior to removal of the material. If it remains in its non - friable state, as defined by the NESHAP, it can be disposed as a conventional construction waste. EPA defines friable as material, when dry, which may be crumbled, pulverized or reduced to powder by hand pressures. C. The Generator of the hazardous material is responsible for the identification and proper handling, transportation, and disposal of the material. Therefore, it is the policy of the City _ of Fort Worth that the Excavator is the Generator regardless of whether the pipe is friable or not. D. It is the intent of the City of Fort Worth that all ACP shall be removed in such careful and prudent manner that it remains intact and does not become friable. The Excavator is responsible to employ those means, methods, techniques and sequences to ensure this result. E.

D-69 COORDINATION WITH THE CITY'S REPRESENTATIVE FOR OPERATIONS OF EXISTING WATER SYSTEMS It is the Contractor's responsibility to coordinate any event that will require connecting to or the operation of an existing City water line system with the City's representative. The Contractor may obtain a hydrant water meter from the Water Department for use during the life of named project. In the event the Contractor requires that a water valve on an existing live system be turned off and on to accommodate the construction of the project, the Contractor must coordinate this activity through the appropriate City representative. The Contractor shall not operate water line valves of existing water system. Failure to comply will render the Contractor in violation of Texas Penal Code Title 7, Chapter 28.03 (Criminal Mischief) and the Contractor will be prosecuted to the full extent of the law. In addition, the Contractor will assume all liabilities and responsibilities as a result of these actions. D-70 ADDITIONAL SUBMITTALS FOR CONTRACT AWARD The City reserves the right to require any pre-qualified contractor who is the apparent low bidder(s)for a project to submit such additional information as the City, in sole discretion may require, including but not limited to manpower and equipment records, information about key personnel to be assigned to the project, and construction schedule, to assist the City in - evaluating and assessing the ability of the apparent low bidders) to deliver a quality product and successfully complete projects for the amount bid within the stipulated time frame. Based upon the City's assessment of the submitted information, a recommendation regarding the award of a 09101/04 SC-52 PART D - SPECIAL CONDITIONS contract will be made to the City Council. Failure to submit the additional information if requested may be grounds for rejecting the apparent low bidder as non-responsive. Affected contractors will be notified in writing of a recommendation to the City Council. D-71 EARLY WARNING SYSTEM FOR CONSTRUCTION Time is of the essence in the completion of this contract. In order to insure that the contractor is responsive when notified of unsatisfactory performance and/or of failure to maintain the contract schedule, the following process shall be applicable: The work progress on all construction projects will be closely monitored. On a bi-monthly basis the percentage of work completed will be compared to the percentage of time charged to the contract. If the amount of work performed by the contractor is less than the percentage of time allowed by 20% or more (example: 10% of the work completed in 30% of the stated contract time as may be amended by change order), the following proactive measures will be taken: 1. A letter will be mailed to the contractor by certified mail, return receipt requested demanding that, within 10 days from the date that the letter is received, it provide sufficient equipment, materials and labor to ensure completion of the work within the contract time. In the event the contractor receives such a letter, the contractor shall provide to the City an updated schedule showing how the project will be completed within the contract time. 2. The Project Manager and the Directors of the Department of Engineering, Water Department, and Department of Transportation and Public Works will be made aware of the situation. If necessary, the City Manager's Office and the appropriate city council members may also be informed. 3. Any notice that may, in the City's sole discretion, be required to be provided to interested individuals will distributed by the Engineering Department's Public T Information Officer. 4. Upon receipt of the contractor's response, the appropriate City departments and directors will be notified. The Engineering Department's Public Information Officer will, if necessary, then forward updated notices to the interested individuals. 5. If the contractor fails to provide an acceptable schedule or fails to perform satisfactorily a second time prior to the completion of the contract, the bonding company will be notified appropriately. D-72 AIR POLLUTION WATCH DAYS The Contractor shall be required to observe the following guidelines relating to working on City construction sites on days designated as "AIR POLLUTION WATCH DAYS". Typically, the OZONE SEASON, within the Metroplex area, runs from May 1, through OCTOBER 31, with 5:00 a.m. - 10:00 a.m. being critical BECAUSE EMISSION'S FROM THIS TIME PERIOD HAVE ENOUGH TIME TO BAKE IN THE HOT ATMOSPHERE THAT LEADS TO EARLY AFTERNOON OZONE FORMATION. . The Texas Commission on Environmental Quality (TCEQ), in coordination with the National Weather Service, will issue the Air Pollution Watch by 3:00 p.m. on the afternoon prior to the WATCH day. On designated Air Pollution Watch Days, the Contractor shall bear the responsibility of being aware that such days have been designated Air Pollution Watch Days and 09101/04 SC-53 PART D - SPECIAL CONDITIONS as such shall not 'begin work until 10:00 a.m. whenever construction phasing requires the use of motorized equipment for periods in excess of 1 hour. However, the Contractor may begin work prior to 10:00 a.m. if use of motorized equipment is less than 1 hour, or if equipment is new and certified by EPA as "Low Emitting", or equipment burns Ultra Low Sulfur Diesel (ULSD), diesel emulsions, or alternative fuels such as CNG. If the Contractor is unable to perform continuous work for a period of at least seven hours between the hours of 7:00 a.m. -6:00 p.m., on a designated Air Pollution Watch Day, that day will be considered as a weather day and added onto the allowable weather days of a given month. D-73 FEE FOR STREET USE PERMITS AND RE-INSPECTIONS A fee for street use permits is in effect. In addition, a separate fee for re-inspections for parkway construction, such as driveways, sidewalks, etc., will be required. The fees are as follows: 1. The street permit fee is $30.00 per permit with payment due at the time of permit application. 2. A re-inspection fee of $25.00 will be assessed when work for which an inspection called for is incomplete. Payment is due prior to the City performing re-inspection. Payment by the contractor for all street use permits and re-inspections shall be considered subsidiary to the contract cost and no additional compensation shall be made. 09/01104 SC-54 L (To be printed on Contractor's Letterhead) Date; DOE No: 3176 PROJECT NAME:Main C1C4B Sanitary Sewer Drainage Area Part 15 MAPSCO LOCATION: 76L LIMNS OF CONST.: West of 9"Avenue along FW'4j+R between Rosedale and Oleander Estimated Duration of Construction on your Street : CXX>days THIS IS TO INFORM YOU THAT UNDER A CONTRACT WITH THE CITY OF FORT WORTH, OUR COMPANY WILL REHABILITATE SEWER LINES ON OR AROUND YOUR PROPERTY.

Afl excavation shall provide an open area conforming to the outside diameter of the casing and/or carrier conduit. The excavation shall be to an alignment and grade which will allow the carrier conduit to be installed to proper line and grade as shown on the Plans and as established in the Specifications. 3. Work shall be performed in accordance with the requirements of the City of Fort Worth Water Department, the Texas department of Transportation, or railroad company, as applicable. B. MATERIALS: 1. Casing Pipe: Casing pipe shall be steel conforming to ANSI B36.10 and the following: a. Field Strength: 35,000 psi minimum. * b. Wall thickness: 0.312 in. minimum (0.5 for railroad crossings). C. Diameter: As shown on the drawings (minimum size requirements), d. Joints: Continuous circumferential weld in accordance with AWS D1.1. 2. Carrier Pipe in Casing: Carrier pipe shall be as shown on drawings and as specified in the General Contract Documents. 3.

Grout: Grout shall be Portland Cement grout of min. 2000 psi compressive strength at 2.8 days. Proportioned not less than 1 cu. ft. of cement to 3 cu. ft. of fine sand with sufficient water added to provide a free flowing thick slurry. C. EXECUTION 1. Where sewer pipe is required to be installed under railroad embankments or under T highways, streets or other facilities in other than open cut, construction shail be performed in such a manner so as to not interfere with the operation of the 11102104 ASC-4 PART DA - ADDITIONAL SPECIAL CONDITIONS railroad, street, highway, or other facility, and so as not to weaken or damage any embankment or structure. During Construction operations, barricades and lights to safeguard traffic and pedestrians shall be furnished and maintained, until such time as the backfill has been completed and then shall be removed from the site. 2. Pits and Trenches: a. If the grade of the pipe at the end is below the ground surface, suitable pits or trenches shall be excavated for the purpose of conducting the jacking or tunneling operations and for placing end joints of the pipe. Wherever end trenches are cut in the sides of the embankment or beyond it, such work shall be sheeted securely and braced in a manner to prevent earth from caving in. b. The location of the pit shall meet the approval of the Engineer. C. The pits of trenches excavated to facilitate these operations shall be backfilled immediately after the casing and carrier pipe installation has been completed, 3. Boring and Jacking Steel Casing Pipe: Steel casing pipe shall be installed by boring hole with the earth auger and simultaneously jacking pipe into place. a. The boring shall proceed from a pit provided for the boring equipment and workmen. The holes are to be bored mechanically. The boring shall be done using a pilot hole. By this method an approximate 2-inch hole shall + be bored the entire length of the crossing and shall be checked for line and grade on the opposite end of the bore from the work pit. This pilot hole shall serve as the centerline of the larger diameter hole to be bored. Other methods of maintaining line and grade on the casing may be approved if acceptable to the Engineer. Excavated material shall be placed near the top of the working pit and disposed of as required. The use of water or other fluids in connection with the boring operation will be permitted only to the extent required to lubricate cuttings. Jetting or sluicing will not be permitted. b. In unconsolidated soil formations, a gel-forming colloidal drilling fluid consisting of at least 10 percent of high grade carefully processed bentonite may be used to consolidate cuttings of the bit, seal the walls of the hole, and furnish lubrication for subsequent removal of cuttings and installation of the pipe immediately thereafter. C. Allowable variation from the line and grade shall be as specified under paragraph A.2. All voids between bore and outside of casing shall be pressure grouted. 4. Installation of Carrier Pipe in Casing: 19/07104 ASC-5 PART DA - ADDITIONAL SPECIAL CONDITIONS a. Sanitary sewer pipe located within the encasement pipe shall be supported by "skids" or "bands" to prevent the pipe and bells from snagging on the inside of the casing, and to keep the installed line from resting on the bells. _ b. All skids shall be treated with a wood preservative. Skids should extend for the full length of the pipe with the exception of the bell area and spigot area necessary for assembly unless otherwise specified. C. The Contractor shall prevent over-belling the pipe while installing it through the casing. A method of restricting the movement between the assembled bell and spigot where applicable shall be provided. d. At all bored, jacked, or tunneled installations, the annular space between the carrier pipe and casing shall be filled with grout. Care must be taken that not too much water is forced into the casing so as not to float the pipe. The backfill material will not be required unless specified on the plans and specified by the Engineer, e. Closure of the casing after the pipe has been installed shall be plugged at the ends of the casing as shown on the drawings or as required by the Engineer. 5. Boring and' Jacking Ductile Iron Pipe without Casing Pipe: a. As indicated on drawings and as required and directed by the Engineer sewer shall be constructed of bore and jacked ductile iron pipe. b. When a casing pipe is not designated on the drawings, the contractor shall provide a casing pipe if necessary to achieve line and grade. Casing pipe shall be provided at no additional cost and shall be subsidiary to the cost bid for installation By Other than Open Cut. C. Bore and jack in accordance with paragraph C.3. above. d. Short length of sewer consisting of a single pipe section may be installed r by jacking without a bore hole if permitted by the Engineer and in soft soil layer. All voids outside of installed pipe shall be pressure grouted. �+ 6. Tunneling: Where the characteristics of the soil, the size of the proposed pipe, or the use of monolithic sewer would make the use of tunneling more satisfactory rt than jacking or boring, or when shown on the pians, a tunneling method may be used, with the approval of the Engineer or railroad/highway officials. a. When tunneling is permitted, the lining of the tunnel shall be of sufficient strength of support the overburden. The Contractor shall submit the proposed liner method to the Engineer for approval. The tunnel liner design shall bear the seal of a licensed professional engineer in the State of Texas. Approval by the Engineer shall not relieve the Contractor of the - responsibility for the adequacy of the liner method. 11102104 ASC-6 1 PART DA - ADDITIONAL SPECIAL CONDITIONS rb. The space between the tunnel liner and the limits of excavation shah be pressure grouted or mud-jacked. C. Access holes for placing concrete shall be space at maximum intervals of 10 feet. D.

INSTALLATION OF THE FiLTER FABRIC (GEOTEXTILE): The geotextile shall be placed in the manner and at the locations shown on the drawings. At the time of installation, the geotextile shall be rejected if it has defects, rips, holes, flaws, deterioration or damage incurred during manufacture, transportation or storage. The surface to receive the geotextile shall be prepared to a relatively smooth condition free of obstructions, depressions, debris, and soft or low density pockets of material. Erosion features such as rills, gullies, etc. must be graded out of the surface before geotextile placement. The geotextile shall be placed with the long dimension perpendicular to the centerline of the channel and laid smooth and free of tension, _ stress, folds, wrinkles, or creases. The strips shall be placed to provide a minimum width of 24-inches of overlap for each joint. Temporary pinning of the textile to help hold it in place until the rock riprap is placed. The temporary pins shall be removed as the riprap is placed to relieve high tensile stress which may occur during placement of material on the geotextile. The specified placement procedure requires that the length of the geotextile be greater than the actual slope length. The Contractor shall adjust the actual length of the geotextile used based on initial installation experience. The geotextile shall be protected at all times during construction from contamination by surface runoff and any geotextile so contaminated shall be removed and replaced with uncontaminated geotextile. Any geotextile damaged during its installation or during placement of riprap shall be replaced by the Contractor at no cost to the Owner.

Before placement of gabion units, the Contractor shall demonstrate that the placement technique will prevent damage to the geotextile. In no case shall any type of equipment be allowed on the unprotected geotextile. 3. RIPRAP PLACEMENT: Stone for riprap shall be placed on the filter fabric blanket in such a manner as to produce a reasonably well graded mass of rock with the minimum practicable percentage of voids and shall be constructed within the specified rt tolerance to the lines and grades shown on the drawings. Then intent of these specifications is to require placement of riprap to the thickness shown and to allow isolated stones to extend as much as six inches above grade. Riprap shall be placed to its full course thickness at one operation and in such a manner as to avoid r displacing the fabric. The larger stones shall be well distributed and the entire mass of stones in their final position shall conform to the gradation specified hereinbefore. 11OW4 ASC-10 PART DA - ADDITIONAL SPECIAL CONDITIONS The finished riprap shall be free from objectionable pockets of small stones and clusters of larger stones. The desired distribution of the various sizes of stones throughout the mass shall be obtained by selective loading of the material at the -' quarry or other source, by controlled dumping of successive loads during final placing, or by other methods of placement which will produce the specified results. Rearranging of individual stones, by mechanical equipment or by hand will be required to the extent necessary to obtain a reasonably well graded distribution of stone specified above. The Contractor shall maintain the riprap protection until accepted. Any material displaced by any cause shall be replaced at his erosion to the lines and grades shown on the Drawings. 4. GROUT PLACEMENT: Grout shall be composed of cement, water and air-entraining admixture and sand mixed in the proportions of 1 part of Portland cement to 3 parts of sand, sufficient water to produce a workable mixture, and that amount of admixture which will entrain sufficient air to produce durable grout, as determined by the _ ENGINEER. Sand for grouting shall conform to the requirements of paragraph: FINE AGGREGATE. The grout shall be mixed in a concrete mixer in the manner specified for concrete except that the time of mixing shall be increased to that necessary to produce a mixture having a consistency such as to permit gravity flow into the interstices of the riprap with the help of limited spading and brooming. The grout shall be used in the work within a period of one (1) hour after mixing. Retempering of ground will not be permitted. Riprap shall not be grouted when the ambient temperature is below 35 degree F. or above 95 degrees F. unless approved by the ENGINEER in writing; nor when the grout, without special protection, is likely to be subjected to freezing temperatures before final set has occurred. Prior to grouting, all surfaces of riprap shall be wetted. The riprap shall be grouted in successive longitudinal strips, approximately 10 feet in width, commencing at the lowest strip and working up the slope. Grout shall be brought to the place of final deposit by approved means, and in no case will grout be permitted to flow on the riprapped surface a distance in excess of 10 feet. Immediately after dumping the batch of grout, it shall be distributed over the surface of the strip by the use of brooms and the grout worked into place between stones with suitable spades, trowels, or vibrating equipment. As a final operation, the grout shall be removed from the top surfaces of the upper stones and from pockets and depressions in the surface of the stone protection. After completion of any strip as specified, no workman or any load shall be permitted on the grouted surface for a period of at least 24 hours. The grouted surface shall be protected from rain, flowing water, and mechanical injury. The surface of all grouted riprap shall be cured by keeping the surface continuously wet for a period of not less than 7 days. E. MEASUREMENT AND PAYME=NT " 1.

While excavating and backfiliing is in progress, traffic shall be maintained, and all utilities and other property protected as provided in the General Conditions and General Requirements. D. Trenches shall be excavated to the depth indicated on the Drawings and in widths sufficient for laying the pipe, bracing and for pumping and drainage facilities. The bottom of the excavations _ shall be firm and dry and in all respects acceptable to the Engineer. Trench width shall be practical minimum_ E. Excavation and dewatering shall be accomplished by methods, which preserve the undisturbed state of subgrade soils, The trench maybe excavated by machinery to,or just below the designated subgrade, provided that material remaining in the bottom of the trench is no more than slightly disturbed, Subgrade soils which become soft, loose, "quick", or otherwise unsatisfactory as a result of inadequate excavation, dewatering or other construction methods shall be removed and replaced by screened gravel fill as required by the Engineer at the Contractor's expense. F_ Clay and organic silt soils are particularly susceptible to disturbance due to construction operations, When excavation is to end in such soils, use a smooth-edge bucket to excavate the last 141 of depth. G. Where pipe is to be laid in screened gravel bedding, the trench may be excavated by machinery to the normal depth of the pipe provided that the material remaining in the bottom of the trench is no more than slightly disturbed. H. Where pipe is to be laid directly on the trench bottom, final excavation at the bottom of the trench shall be performed manually,providing a flat-bottom true to grade upon undisturbed material. Bell holes shall be made as required. 3.02 DISPOSAL OF MATERIALS A. Excavated material shall be stacked without excessive surcharge on the trench bank or obstructing free access to hydrants and gate valves.

It is expressly understood that no excavated material shall be removed from the site of the work or disposed of, except as directed by the Engineer, When removal of surplus materials has been approved by the Engineer,dispose of such surplus material in approved designated areas. C. Should conditions make it impracticable or unsafe to stack material adjacent to the trench,the material shall be hauled and stored at a location designated by the Owner. When required, it shall be re-handled and used in backfilling the trench. 3.03 SHEETING.AND BRACING A. Furnish,put in place and maintain sheeting and bracing required by Federal,State or local safety requirements to support the sides of the excavation and prevent loss of ground which could endanger personnel,damage or delay the work or endanger adjacent structures. If the Engineer is of the opinion that at any point sufficient or proper supports have not been provided,he/she may order additional supports placed at the expense of the Contractor. Compliance with such order shall not relieve the Contractor from his/her responsibility for the sufficiency of such supports. rrsll 6659so2.221 02221-3 7111105 a City of Fort Worth NSH Wafer Main Extension Unit 4 —Cantrell-Sansom P5 to future Basswood BotOevard Unit 5A-Future Noeth Tarrant Parkway,between Harmon Road and I1-135W Care shall be taken to prevent voids outside of the sheeting, but if voids are formed, they shall be immediately filled and rammed. B. Where sheeting and bracing is required to support the sides of trenches, engage a professional engineer, registered in the State of Texas, to design the sheeting and bracing. The sheeting and bracing installed shall be in conformity with the design and certification of this shall be provided by the professional engineer. C. When moveable trench bracing such as trench boxes,moveable sheeting,shoring or plates are used to support the sides of the trench, care shall be taken in placing and moving the boxes or supporting bracing to prevent movement of the pipe,or disturbance of the pipe bedding and the screened gravel backfill. 1. When installing rigid pipe, any portion of the box extending below mid diameter shall be raised above this point prior to moving the box ahead to install the next pipe. This is to prevent the separation of installed pipe joints due to movement of the box. 2. When installing semi-rigid pipe trench boxes,moveable sheeting,shoring or plates shall not be allowed to extend below mid-diameter of the pipe. As trench boxes, moveable sheeting, shoring or plates are moved,screened gravel shall be placed to fill any voids created and the screened gravel and backfill shall be recompacted to provide uniform side support for the pipe. P. Permission will be given to use steel sheeting in lieu of wood sheeting for the entire job wherever the use of sheeting is necessary. The cost for use of sheeting will be included in the bid items for pipe and shall include full compensation for driving,bracing and later removal of sheeting. E. All sheeting and bracing shall be carefully removed in such manner as not to endanger the construction of other structures, utilities, or property, whether public or private.

B. if the Contractor excavates below grade through error or for the Contractor's own convenience,or through failure to properly dewater the trench,or disturbs the subgrade before dewatering is sufficiently complete,he/she may be directed by the Engineer to excavate below grade as set forth in the following paragraph, in which case the work of excavating below grade and furnishing and placing the refill shall be performed at his/her own expense. C. If the material at the level of trench bottom consists of fine sand,sand and silt or soft earth which may work into the screened gravel notwithstanding effective drainage,the subgrade ]na:erial shall be removed to the extent directed and the excavation refilled with a 6-in layer of coarse sand,or a mixture graded from coarse sand to the rine peastone, as approved by the Engineer,to form a filter layer preserving the voids in the gravel bed of the pipe. The composition and gradation of gravel shall be approved by the Engineer prior to placement.. Gravel backfill shall then be placed in 6-in layers thoroughly compacted up to the normal grade of the pipe. D. Geotextile filter fabric may be substituted for filter layer if approved by the Engineer. Filter fabric shall be Mirafi 140N; Supac;equivalent,or equal. 3.06 BACKFILLING _ A. As soon as practicable after the pipe has been laid and jointed,backfilling shall begin and thereafter be prosecuted expeditiously.

Where the pipes are laid in the yard,the remainder of the trench shall be filled with common fill material in layers not to exceed 3-ft and mounded 6-in above the existing grade or as directed. Where a loam or gravel surface exists prior to excavations in the yard, it shall be removed, conserved and replaced to the full original depth as part of the work under the pipe items. In some areas it may be necessary to remove excess material during the cleanup process,so that the ground may be restored to its original level and condition. C. Where the pipes are laid in paved areas, the remainder of the trench up to a depth of 1-ft below the bottom of the specified permanent paving shall be backfilled with common fill material in layers not to exceed 1-ft and thoroughly compacted. The subbase layer for paving shall be of bank-run gravel thoroughly compacted in 6-in layers. D. To prevent longitudinal movement of the pipe,dumping backfill material into the trench and then spreading will not be perrrritted until selected material or screened gravel has been placer/and compacted to a level l-ft over the pipe. E. Backfill shall be brought up evenly on all sides. Each layer of backfill material shall be thoroughly compacted by rolling,tamping, or vibrating with mechanical compacting equipment or hand tamping, to 95 percent compaction. If rolling is employed, it shall be by use of a suitable roller or tractor, being careful to compact the fill throughout the full width of the trench.

(See Figures 1 and 2) This is Conclusion:Henry Pratt seat on body designs which important because build up can interfere with the swing do not depend on retaining hardware in the waterway radius of the disc.Additionally, seats on body are for seat retention have recognized these potential recessed and thus more protected than seat on disc problems and addressed them in advance.Successful designs. field performance has substantiated the credibility of this design approach!l Rubber Seat on Disc - Pratt — Rubber Seat on Body Designs Design by Others r.�,r•�f %'•��:ti`; .�.1 ,� •.mss ��ti•, � ,�.' � � �''�:.

No action is required on your part. Disclosure of Terrorism Premium The premium charge for risk of loss resulting from acts of terrorism(as defined in the Act)under this bond is $—waived!. This amount is reflected in the total premium for this bond. Disclosure of Availability of Coverage for Terrorism Losses As required by the Terrorism Risk Insurance Act of 2002,we have made available to you coverage for losses resulting from acts of terrorism:(as defined in the Act)with terms,amounts, and limitations that do not differ rnaterially as those for losses arising from events other than acts of terrorism. Disclosure of Federal Share of Insurance Company's Terrorism Losses The Terrorism Risk Insurance Act of 2002 establishes a mechanism by which the United States government will share in insurance company losses resulting from acts of terrorism(as defined in the Act)after a insurance company has paid losses in excess of an annual aggregate deductible. For 2002, the insurance company deductible is I% of direct earned premium in the prior year; for 2003, 7%of direct earned premium in the prior year; for 2004, 10% of direct earned premium in the prior year; and for 2005, 15%of direct earned prem.iurn in the prior year. The federal share of an. insurance company's losses above its deductible is 90%. In the event the United States government participates in losses, the United States government may direct insurance companies to collect a terrorism surcharge from. policyholders. The Act does not currently provide for insurance industry or United States government participation in terrorism losses that exceed$100 billion in any one calendar year. Definition of Act of Terrorism The Terrorism Risk Insurance Act defines "act of terrorism"as any act that is certified by the Secretary of the Treasury, in concurrence with the Secretary of State and the Attorney General of the United States: 1. to be an act of terrorism; 2, to be a violent act or an act that is dangerous to human life,property or infi-astructure; 1 to have resulted in damage within the United States, or outside of the United States in the case of an air carrier (as defined in section 40102 of title 49,United 17 States Code)or a United States flag vessel (or a vessel based principally in the United States, on which United States income tax is paid and whose insurance coverage is subject to regulation in the United States),or the premises of a United States mission;and 4. to have been committed by an individual or individuals acting on behalf of any foreign person or foreign interest as part of an effort to coerce the civilian population of the United States or to influence the policy or affect the conduct of the United States Government by coercion.
