Store No.24638 6521 McCart Ave. Fort Worth,TX 76133 Dear Mr. Gange: Shaw Environmental Inc. (Shaw) has been retained by 7-Eleven, Inc. to perform an environmental assessment of the soil and groundwater at the above-referenced site (Site). On August 16, 2005, a pressure decay test failure was detected by Tanknology in the spill buckets on the mid-grade unleaded and premium unleaded tanks. The spill buckets were isolated and replaced on August 22, 2005. The pea gravel (fill) samples were collected from the bottom of the spill buckets by Shaw during replacement and delivered to Star Analytical Laboratory (Star) in Fort Worth, Texas. The sample results were above the action levels as outlined in TCEQ guidance document RG-411. An LPST issuance letter was received on February 3, 2006 requesting an Affected Property Assessment Report (APAR) be completed after delineation of the appropriate contaminants-of-concern (COCs) to the appropriate Protective Concentration Levels (PCLs). In order to complete the APAR, groundwater contamination must be delineated in all directions. Shaw has completed assessment onsite and has determined that offsite delineation is needed. To complete the TCEQ requirements, Shaw must install a monitoring well in the median at the south corner of the intersection of McCart Avenue and Westcreek Drive. The TCEQ letter dated February 3, 2006, requesting an APAR for the Site is included as Attachment A. Attachment B outlines Shaw's placement of the well on a scaled site map as well as a scaled aerial photograph. Please review and approve this request for further processing. Shaw appreciates your prompt attention in this matter. If you have any questions, or require additional information, please contact Christopher Mabe at(214)277-7865.

Be aware that if you permanently remove your underground storage tank(UST) system from service, you are required to submit permanent-removal-from-service documentation (if not submitted previously) in accordance with 30 TAC §334.55. For reporting and sampling requirements for both USTs and above- ground storage tanks(ASTs),please refer to Investigating and Reporting Releasesfrom PSTs(RG-411). You must also submit revised UST or AST tank registration forms(TCEQ-0724 or TCEQ-0659,respectively)to the TCEQ PST Registration Team(address is on forms) when tanks are removed from service. Please note that all correspondence, clearly labeled with both the LPST and facility ID numbers, should be submitted to the Central Office in Austin. Should you have any questions,please contact me at 512/239-2200 and reference the assigned LPST ID number. We appreciate your cooperation. Sincerely, Stacey J.

Store No.24638 6521 McCart Avenue Fort Worth,Texas 76133 Dear Mr. Breitling: On behalf of 7-Eleven, Inc, Shaw Environmental, Inc. (Shaw) has enclosed a response to the City of Fort Worth letter dated September 1, 2006 regarding additional information required to grant an informal request to place a monitor well and conduct subsurface sampling within the City of Fort Worth Right-of- Way along WestCreek Drive and McCart Avenue. The soil and groundwater sample results, as submitted with Release Determination Report in November 2005 and during subsequent groundwater sampling events, exhibited concentrations above the Action Levels in MW-1 and MW-2 (see Table 1 and Table 2). Copies of laboratory analytical results are included in Attachment A. The groundwater gradient is towards northeast (see Figure 1). Shaw has completed assessment onsite and has determined that offsite delineation is needed. To complete the TCEQ requirements, Shaw must install a monitoring well in the median at the south corner of the intersection of McCart Avenue and Westcreek Drive. The protocol for drilling, maintaining and removing off-site well as well as sampling procedure is included in Attachment B. Figure 2 shows the site map with proposed monitoring well location and underground utility lines. Figure 3 shows the site vicinity map. Should you have any questions concerning the site activity or this project, please call Mica Feinstein, at (214)277-7818. Sincerely, Shaw Environmental, Inc.

T14023 Co-nto :e: ATTACHMENT B PROTOCOL FOR DRILLING, MAINTAINING AND REMOVING OFF-SITE WELL The proposed monitor well will be installed to an appropriate depth below ground level. It will be drilled with a mobile drilling rig, direct push equipment, or with a "hand-auger", depending on overhead and available space restrictions. The monitor well will be constructed with threaded, PVC pipe and installed properly to meet all appropriate local/state water well rules and regulations. The top of the monitor well will be completed to be at, or slightly below, ground level and will be encased in a "water-tight" steel manhole box and secured in order to protect it and not interfere with typical, every day use of the land around it. The length of time required for installation is approximately four(4)to six(6) hours (actual time may vary). The area around the proposed monitor well will be cleaned up after installation is completed. Groundwater will be checked with an electronic probe and samples collected from the monitor well once per quarter, or as directed by appropriate regulatory agency. These activities will typically be completed by one (1) person. The length of time required for this activity is approximately one and one-half (1 Yz) hours per quarter. When the monitor well is no longer needed or required by the regulatory agency for groundwater monitoring, to the extent permitted to do so, the Environmental Consultant will plug the monitor well according to appropriate State Water Well Rules and Regulations. After the monitor well is plugged, the area around it will be restored as stated in the temporary access agreement. SAMPLING PROCEDURES AND ANALYTICAL METHODS Soil Sampling - Representative samples throughout the soil column will be collected from the selected interval and containerized in unpreserved laboratory-supplied 4-oz glass jars equipped with Teflon TM-lined lids. The jarred samples will be properly labeled and immediately placed on ice. With the exception of the disposable gloves worn by the geologist (which will be changed prior to every sample collected), all reusable equipment will be decontaminated using a distilled water and AlconoxTM wash with a distilled water rinse. The cooler containing all soil samples will then be submitted to NELAC approved laboratory under proper chain-of-custody. Soil samples will be submitted for the analyses of BTEX/MTBE utilizing EPA Method 8021 B and total petroleum hydrocarbons (TPH) utilizing TCEQ Method TX1005. The soil sample that exhibit the highest TPH concentration in the C12-C35 range will be analyzed for polycyclic aromatic hydrocarbons (PAH) utilizing EPA Method 8270C. Groundwater Sampling — Before groundwater samples be collected, the monitoring well (MW) will be gauged and the depth to initial water level and total well depth will be recorded. The MW will be manually purged of three well volumes or until dry using a cleaned 1.5-inch diameter polyvinyl chloride (PVC) bailer and nylon rope. Disposable latex gloves will be changed prior to every sample collection. For BTEX, MTBE, and TPH analyses, the groundwater samples will be placed in 40-milliliter vials with TeflonTm-lined lids. The containers will be filled completely, leaving no headspace, and acidified to a pH of less than two (2.0) with hydrochloric acid. For PAH analysis, groundwater samples will be placed in 500-mL amber bottles. The groundwater samples will be stored on ice and hand-delivered to NELAC-approved laboratory following strict chain-of-custody procedures. The groundwater samples will be submitted to the laboratory for the chemical analyses of BTEX/MTBE utilizing EPA Method 8021 B and total petroleum hydrocarbons (TPH) utilizing TCEQ Method TX1005. The groundwater sample with the highest TPH in the C12-C35 range will be analyzed for PAH per EPA Method 8270C. Exhibit C: I Shaw Environmental,Inc. 6330 Commerce Drive DEC: 1 2 2006 Suite 190 Irving,TX75063 214.277-7800 `•, FAX:214.277-8600 �11W Shaw Environmental, Inc. December 1, 2006 Mr. Chris Breitling City of Fort Worth Environmental Management Department 1000 Throckmorton Street Fort Worth, Texas 76102-6311 RE: Formal Request for Temporary Access—Monitoring Well Installation Near 7-Eleven, Inc.Store No.24638 6521 McCart Avenue Fort Worth,Texas Mr. Breitling, Shaw Environmental, Inc. (Shaw) has been retained by 7-Eleven, Inc. (7-Eleven)to perform an environmental assessment of the soil and groundwater at the above-referenced site. On August 16, 2005, a pressure decay test failure was detected by Tanknology in the spill buckets on the mid-grade unleaded and premium unleaded tanks. The spill buckets were isolated and replaced on August 22, 2005. The pea gravel (fill)samples were collected from the bottom of the spill buckets by Shaw during replacement and delivered to Star Analytical Laboratory(Star)in Fort Worth, Texas. The sample results were above the action levels as outlined in TCEQ guidance document RG-411. An LPST issuance letter was received on February 3, 2006 requesting an Affected Property Assessment Report(APAR)be completed after delineation of the appropriate contaminants-of-concern (COCs)to the appropriate Protective Concentration Levels (PCLs). In order to complete the APAR, groundwater contamination must be delineated in all directions. Shaw has completed assessment onsite and has determined that offsite delineation is needed. To complete the TCEQ requirements,Shaw would like to install a monitoring well in the median at the south corner of the intersection of McCart Avenue and Westcreek Drive. An informal request for sub-surface environmental sampling on City of Fort Worth property was originally submitted on August 11, 2006 and was granted on October 23, 2006. A synopsis of the history of the LPST site associated with the request is included in Attachment 1. The groundwater samples collected from on-site monitoring wells (MW-1 through MW-3)indicated concentrations above applicable residential Action Levels for benzene and MTBE in MW-1 and MW-2. In order to delineate the benzene and MTBE plumes, the installation of a monitoring well in the median on the southern comer of the intersection of McCart Avenue and Westcreek Drive is necessary. The proposed monitoring well location is based on the downgradient groundwater water flow direction and distance from the 7-Eleven property(approximately 30 feet).Walgreens is located across Westcreek Drive in the downgradient direction and is approximately 120 feet from the 7-Eleven site location.

The proposed monitor well will be installed to a depth of approximately 35 feet below ground level. It will be drilled with a mobile drilling rig with the first 4-5' being advanced by hand to decrease the potential of damaging any unlocated underground utility. Samples will be collected continuously using a 5' core barrel. The well will be constructed with threaded 2"diameter schedule 40 polyvinyl chloride (PVC) pipe and installed properly to meet all appropriate local/state water well rules and regulations. The top of the well will be completed to be at, or slightly below ground level and will be encased in an 8" diameter, 'water-tight' steel manhole box in order to protect the well and not have the wells location interfere with typical every day use of the land around it. The length of time required for installation will be approximately four to six hours (actual time may vary). The area around the proposed well will be cleaned up after installation has been completed. Representative samples throughout the soil column were collected from the selected interval and the soil samples will be split into two portions. The first portion of each soil sample will be containerized in unpreserved laboratory-supplied 4-oz glass jars equipped with Teflon"m-lined lids. The jarred samples were properly labeled and immediately placed on ice. The second portion of the soil sample will be allowed to volatilize within the ziplock sample bag. Next, an organic vapor meter (OVM) or a photo-ionization detector (PID) will analyze the airspace within the sample bags to determine which soil sample contained the highest concentration of hydrocarbons. The soil samples from the following intervals will be collected and submitted to the laboratory: 0-2'; the sample with the highest hydrocarbon concentration (highest PID reading); and 22.5- 25' (or bottom of boring). With the exception of the disposable gloves worn by the geologist (which will be changed prior to every sample collected), all reusable equipment will be decontaminated using a distilled water and Alcono)J"wash with a distilled water rinse. A cooler containing all soil samples will be submitted to NELAC approved laboratory under proper chain-of- custody. Soil samples will be submitted for laboratory analysis of Benzene, Toluene, Ethylbenzene, Total Xylenes (BTEX) and Methyl t-butyl ether (MTBE) per Environmental Protection Agency (EPA) Method 8021 B and Total Petroleum Hydrocarbons (TPH) per EPA Method TX 1005. The soil sample that exhibits the highest TPH concentration in the C12-C35 range will be analyzed for polycyclic aromatic hydrocarbons (PAH) utilizing EPA Method 8270C. Soils generated during drilling will be placed in properly labeled 55-gallon drums, kept on-site at 6251 McCart Avenue and disposed of to the landfill, assuming that the soil is non-hazardous waste, per TCEQ and Texas Department of Health (TDH) guidelines. One composite soil sample will be collected from the soil cuttings and analyzed for BTEX, TPH, total lead, and Reactivity, Conductivity, and Ignitability (RCI) for disposal purposes. ATTACHMENT 7 Equipment A mobile drilling rig will be used to install the well. The first 5' will be advanced by hand with either a hand auger or post-hole digger. A hole approximately 7-inches in diameter will be cut through the ground. The well will then be drilled with approximately 7-inches diameter hollow stem augers with 5-feet split core barrels for sampling. The well will be drilled to an approximate depth of 35 feet. The well will be completed with 2.5-feet of 2-inch schedule 40 PVC casing, and 27.5-feet of 0.001-inch slot PVC screen. Filtered sand will be added from 27-feet to 2-feet; bentonite will be added from 2-feet to 1-foot; and concrete will be added from 1-foot to the surface. The concrete will be in and around an 8"diameter steel manway, which will provide access to the well. The well cap will be secured with a lock. Later, the wells will be gauged with an interface probe and sampled with new disposable bailers. ATTACHMENT 8 Groundwater Monitoring Procedures Shaw Environmental, Inc. personnel will collect groundwater samples from the newly installed monitoring well and the previously installed on-site monitoring wells. Groundwater samples will be collected quarterly. Before groundwater samples will be collected, the monitoring well will be gauged using an Interface Probe, and the depth to initial water level and total well depth was recorded. Each MW will be manually purged of a minimum of three well volumes or until dry using a new disposable polyvinyl chloride (PVC) bailer and nylon rope. The purge water will be collected in 5-gallon buckets. Disposable latex gloves will be changed prior to every sample collection. Groundwater samples will be collected using a single-use, disposable 1.5-inch PVC bailer and placed into laboratory provided clean sample jars. For BTEX, MTBE, and TPH analyses, the groundwater samples will be placed in 40-milliliter vials with TeflonTm-lined lids. The containers will be filled completely, leaving no headspace, and acidified to a pH of less than two (2.0) with hydrochloric acid. For PAH analysis, groundwater samples will be placed in 500-mL amber bottles. The groundwater samples will be stored on ice and will be submitted to NELAC-approved laboratory following strict chain-of-custody procedures. The groundwater samples will be submitted to the laboratory for the chemical analyses of BTEX/MTBE utilizing EPA Method 8021 B and total petroleum hydrocarbons (TPH) utilizing TCEQ Method TX1005. The groundwater sample with the highest TPH in the C12-C35 range will be analyzed for PAH per EPA Method 8270C. Sampling procedures will take approximately one hour per monitoring well and all purge water will be consolidated and kept on the 7-Eleven property in Department of Transportation (DOT) approved 55-gallon drums, pending disposal. ATTACHMENT 9 Schedule of Use The proposed monitoring well will be installed approximately 10 days after approval has been granted. Upon completion, this monitoring well will be sampled at least on a quarterly basis and is estimated to be in use for 2- 4 years (or to the schedule recommended by the TCEQ). All sampling procedures (gauge, bail, and sample collection) will take approximately one hour and shall be conducted at such a time as not to interfere with any regular traffic build-ups (or during City of Fort Worth's scheduled hours designated for road work). ATTACHMENT 10 Plugging and Abandon Procedures When the well is no longer needed or required by the regulatory agency for groundwater monitoring, to the extent permitted to do so, the Environmental Consultant will plug and abandon the well according to appropriate State Water Well Rules and Regulations. After the well is plugged and abandoned, the area around it will be restored to the previous condition. ATTACHMENT 11 Contacts Driller: Strata Core, Inc.
