The property has coordinates of 44°SQ'33" latitude and 93°09'00" longitude. The eastern three-fourths of the property is ? located in the southeast quarter of the northeast quarter of Section 10, Township 27 North ('T27N), Range 23 West (R23V). The western one-fourth of the property is located in the ? southwest quarter of the northeast quarter of Section 10, Township 27 North (T27N), Range 23 West (R23V). The property is located in Dakota County. A site locarion map is ? included as Figure 1. , 2.2 Site Ownershiu ' The U.S. Postal Service (USPS) owns and operates the Bulk Mail Center. The USPS contact person is: ? Mr. Roger Leitch ? U.S. Postal Service Facilides Service Office 2051 Killebrew Drive ? Suite 620 Bloomington, MN 55425-1874 ? (612) 851-1157 e 2.3 Site Description ' The Bulk Mail Center is comprised of a Process Building, Vehicle Service Center, and an Enclosed Vehicle Shelter. The service center and shelter aze used for general maintenance ' and servicing of postal vehicles. The site is bounded by Lexington Ayenue to the east and a wooded area to the north, south, and west. The properties located across Lexington Avenue, ? 3 I ¦ adjacent to the Bulk Mail Center are currently owned by 3M and Shaw Industries. To the , south, adjacent to the wooded area, aze residential properties located approximately one block from the subject property. , A map showing the "Process Building Area," the "Vehicle Service Center Area," and all ? pertinent site features are presented in Figure 2. Utilities located in the UST basin areas aze shown in Figures 3 and 4. ? 2.4 Undereround Storage Tank Information ? Six USTs, associated product lines, and pump island and dispensers were removed from this , site and one UST was ciosed in place between July 10 and August 13, 1991. The USTs are documented by the Postal Service as being installed in 1975. The tanks aze listed in Table 1 ' and the locations are shown in Figure 2. ' 2.4.1 Process Buildin,g Area ' USTs 1 and 2, two former 19,000-gallon heating oil USTs, located approximately 115 feet north of the Process Building on the east side of the driveway were removed and replaced by ? one 25,000-gallon heating oil UST. The two headng oil tanks were used as a backup to the natural gas heating system, but had not been in use for a couple of years. , 2.4.2 Vehicle Service Center Area ? UST 3, a 2,000-gallon hearing oil tank, iocated on the north side of the Vehicle Service , Center was removed and replaced by a 2,500-gallon heating oil UST. UST 4, a 4,000- gallon gasoline tank, and UST 5, a 4,000-gallon diesel tank, located on the east side of the Vehicle Service Center, were removed and replaced by one 10,000-gallon diesel UST and ? one 10,000-gallon gasoline UST. The dispensers and lines, located north of USTs 4 and 5, were also removed and replaced. UST 6, a 560-gallon waste oil tank located on the east side ? 4 I ? of the Vehicle Service Center was removed and UST 7, a 560-gallon waste oil UST located ? on the southwest side the Vehicle Service Center was closed in place due to the proximity of gas and sewer lines. ? The headng oil tank was used as a backup to the natural gas heating system, but had not ' been in use for a couple of years. The Eagan Post Office used the gasoline tank to service camer vehicles, and the diesel tank to service tractors. The two waste oil tanks were used ? for storing waste oil products generated at the service bays in the Vehicle Service Center. 1 2.5 Petroleum Release Information ? There are no documented reports of an uncontrolled release of petroleum products from this site prior to the documentation of the release detected during the excavation of the six USTs. , 2.5.1 Process Building Area ' During the excavation of the two 19,000-gallon heaUng oil tanks (USTs 1 and 2), DPRA ? detected elevated organic vapor concentrations with the PID in the soils surrounding the tanks. Elevated PID readings were also recorded in soils below the pipe lines during f+ removal. Both USTs appeared to be in good condition with no visible holes or pitting. The cause of the elevated PID readings in the two heating oil basins is unknown; however, it is i suspected that overfills and spills are a possible cause of release. ', 2.5.2 Vehicle Service Center Area , During the excavation of USTs 4, 5, and 6, DPRA detected elevated organic vapor ? concentrations with the PID in the soils sunounding the tanks. Extensive conosion and a few small holes were observed in UST 6, the waste oil tank, and conosion with some pitting ? was observed in both USTs 4 and 5, the gasoline and diesel tanks. During the excavation of UST 3, the 2,000-gallon heating oil tank, elevated PID readings were recorded in the soil ? 5 11 I sunounding the tank. UST 3 appeared to be in good condition with no visible holes or ? pitting. Overfills and spills aze a possible -cause of the release. Elevated PID readings were also recorded in soils below dispensers and lines during removal. I I I r I I t I I I t 6 , I 3.0 EXCAVATION RESULTS ? Between July 10 to July 31, 1991, Pump and Meter Service, under contract with the USPS, ? removed and disposed of six USTs located at the U.S. Postal Service Bulk Mail Center. In addition, one UST was closed in place. DPRA personnel were on site to observe and ? document the condition and removal of the USTs and their surrounding soils. Visual observations made and data collected during the UST excavarions are presented on the ? MPCA form "Excavation Report for Petroleum Release Sites." This form is included as Appendix A. ? 3.1 Process Building Area ? A discussion of the results of the excavations of USTs 1 and 2 located approximately 115 ? feet north of the Process Buiiding is provided in the following sections. ' 3.1.1 Field Observations and PID Measurements ? As the USTs were excavated, soil vapor samples were collected and screened with an HNU Model 101 PID equipped with a 102 eV lamp and calibrated for direct readings in parts per ? million (ppm) volumeJvolume of benzene. The soil vapor samples were analyzed using jar headspace analysis in accordance with MPCA guidelines. According to MPCA guidance ? documents, PID measurements above background (0.0 ppm) in the soils surrounding the fuel oil tanks are considered contaminated. ? PID readings ranged from 1.5 to 40 .ppm during the excavation of UST 1, 1.0 to 30 ppm ? during the excavation of UST 2, and 0.0 to 300 ppm during the removal of the associated ? piping. The highest readings were recorded in soils azound the fill pipe of USTs 1 and 2 and below the associated pipe lines. The soil vapor sample locations aze shown in Figure 5, and ? the PID readings from azeas within the excavations and along the pipe line trench aze presented in the MPCA's Excavation Report form in Appendix A. ? 7 I ? The two 19,000-gallon heating oil USTs were cathodically protected and coated steel tanks. ? Both tanks were in good condition with no visible holes or pitting noted during excavation and removal. The backfill material within the UST 1 and 2 basins consisted of silty sand, ? and the native soil within both basins consisted of a sandy clay. The dimensions of the two excavations were as follows: the UST 1 basin was approximately 50 feet long by 29 feet ? wide by 16.5 feet deep; and the UST 2 basin was approximately 37 feet long by 22 feet wide by 15 feet deep. The limits of the excavations aze shown in Figure 3. A total of ? approximately 75 cubic yards of contaminated soil was removed from the UST 1 and 2 basins and along the pipe lines. ? 3.1.2 Analytical Results ? After excavation of the tanks, piping, and contaminated soil was completed the following ? eleven (11) soil samples were collected to represent the final extent of the excavation: two from the bottom of the UST 1 basin, SS-8 and SS-9, four from the sidewalls of the UST 1 ? basin, SS-1, SS-6, SS-7, and SS-10, two from the bottom of the UST 2 basin, SS-11 and SS- 17, and three from beneath the associated piping, P-1, P-2, and P-3. All samples were ? submitted to the laboratory for analysis for BETX, and TH as fuel oil. Soil sample locations are presented in Figure 5. This information is also presented in the MPCA's Excavation ? Report in Appendix A. ? Analysis of the samples detected low levels of petroleum constituents. Benzene was detected at 0.010 ppm in samples P-1 and P-3, collected from beneath the piping at 7 feet below , ground surface. The analytical results of the remaining samples were below method detection limits. ? ? In addition, three soil samples, SP-1, SP-2, and SS-19, were collected from stockpiled soil and submitted to the laboratory for analysis for BETX and TH as fuel oil. TH as #2 fuel oil ? was detected at 3 ppm in stockpile sample SP-2. 1 8 I I I ' , , APPENDIX A I EXCAVATION REPORT FOR PETROLEUM RELEASE STTES , I I I ' , a 1 Fl, 1 1 t 1 I r EXCAVATION REPORT FOR PETROLEUM RELEASE SITES ' Minnesota Pollution Control Agency Tank and Spills Section May 1991 r The information below should be completed and submitted to the Minnesota Pollution Control Agency (MPCA) Tanks . and Spills Section to document excavation of peuoleum contaminated soil.

The U.S. Postal Service (LTSPS) conlracted with DPRA Incorporated (DPRA) to observe and ' document the removal of seven underground storage tanks (USTs) at the U.S. Postal Service Bulk Mail Center in Eagan, Minnesota. Following the UST removals the USPS contracted ? with DPRA to conduct a remedial investigation to document the degree and extent of petroleum contamination. ' On July 10, 1991, a release was reported to the Minnesota Pollution Control Agency , (MPCA). 1fie MPCA has assigned Site I.D. #: LEAK00004230 to this site. ' 1.1 Pum ' The purpose of this investigation was to assess the condition of the USTs and the soil surrounding and below the USTs, to identify actual or potential impacts of the release, and to ? recommend further action based on the findings. , 1.2 Scone of Services , The scope of services performed by DPRA at this site consisted of the following activities: , • Screened soil samples collected during the UST excavations with a portable HNiJ Model 101 photoionization detector (PID). ? • Documented the conditions of seven USTs, their associated piping, and the soil within the UST excavations during tank removal. , • Submitted selected soil samples for analysis for benzene, ethylbenzene, toluene, and xylenes (BETX), methyl tertiary butyl ether (MTBE), total , hydrocarbons (TH) as gasoline and fuel oil, volatile organic compounds (VOCs), polychlorinated biphenyl (PCBs), cadmium, chromium, and lead. ' 0 Documented the treatment of petroleum-contaminated soil. ? ? ? ? ' ? ? ? ' ' ? , ? , ' , ' ? ? • Directed the advancement of three (3) standard penetration soil borings. • Screened soil samples recovered from the soil borings with a portable HNiJ Model 101 PID. • Collected soil samples from each boring and submitted the samples for chemical analysis for benzene, ethylbenzene, toluene, and xylenes (BETX), methyl tertiary butyl ether (MTBE), and total hydrocarbons (TH) as gasoline and fuel oil. • Advanced two hand auger borings within the proximity of UST 7, which was closed in place. • Collected soil samples from each boring and submitted the samples for chemical analysis for VOCs, PCBs, TH as fuel oil, cadmium, chromium, and lead. • Prepazed a Remedial Investigation (RI) report which sarisfies the MPCA requirements. The remaining sections of this report include background information, excavation results, remediation investigation results, discussions, conclusions, and recommendations. 2 i 1 , 2.1 Site I.ocation 2.0 BACKGROUND INFORMATION ?

The two headng oil tanks were used as a backup to the natural gas heating system, but had not been in use for a couple of years. , 2.4.2 Vehicle Service Center Area ? UST 3, a 2,000-gallon hearing oil tank, iocated on the north side of the Vehicle Service , Center was removed and replaced by a 2,500-gallon heating oil UST. UST 4, a 4,000- gallon gasoline tank, and UST 5, a 4,000-gallon diesel tank, located on the east side of the Vehicle Service Center, were removed and replaced by one 10,000-gallon diesel UST and ? one 10,000-gallon gasoline UST. The dispensers and lines, located north of USTs 4 and 5, were also removed and replaced. UST 6, a 560-gallon waste oil tank located on the east side ? 4 I ? of the Vehicle Service Center was removed and UST 7, a 560-gallon waste oil UST located ? on the southwest side the Vehicle Service Center was closed in place due to the proximity of gas and sewer lines. ? The headng oil tank was used as a backup to the natural gas heating system, but had not ' been in use for a couple of years. The Eagan Post Office used the gasoline tank to service camer vehicles, and the diesel tank to service tractors. The two waste oil tanks were used ? for storing waste oil products generated at the service bays in the Vehicle Service Center. 1 2.5 Petroleum Release Information ? There are no documented reports of an uncontrolled release of petroleum products from this site prior to the documentation of the release detected during the excavation of the six USTs. , 2.5.1 Process Building Area ' During the excavation of the two 19,000-gallon heaUng oil tanks (USTs 1 and 2), DPRA ? detected elevated organic vapor concentrations with the PID in the soils surrounding the tanks. Elevated PID readings were also recorded in soils below the pipe lines during f+ removal. Both USTs appeared to be in good condition with no visible holes or pitting. The cause of the elevated PID readings in the two heating oil basins is unknown; however, it is i suspected that overfills and spills are a possible cause of release. ', 2.5.2 Vehicle Service Center Area , During the excavation of USTs 4, 5, and 6, DPRA detected elevated organic vapor ? concentrations with the PID in the soils sunounding the tanks. Extensive conosion and a few small holes were observed in UST 6, the waste oil tank, and conosion with some pitting ? was observed in both USTs 4 and 5, the gasoline and diesel tanks. During the excavation of UST 3, the 2,000-gallon heating oil tank, elevated PID readings were recorded in the soil ? 5 11 I sunounding the tank. UST 3 appeared to be in good condition with no visible holes or ? pitting. Overfills and spills aze a possible -cause of the release. Elevated PID readings were also recorded in soils below dispensers and lines during removal. I I I r I I t I I I t 6 , I 3.0 EXCAVATION RESULTS ? Between July 10 to July 31, 1991, Pump and Meter Service, under contract with the USPS, ? removed and disposed of six USTs located at the U.S. Postal Service Bulk Mail Center. In addition, one UST was closed in place. DPRA personnel were on site to observe and ? document the condition and removal of the USTs and their surrounding soils. Visual observations made and data collected during the UST excavarions are presented on the ? MPCA form "Excavation Report for Petroleum Release Sites." This form is included as Appendix A. ? 3.1 Process Building Area ? A discussion of the results of the excavations of USTs 1 and 2 located approximately 115 ? feet north of the Process Buiiding is provided in the following sections. ' 3.1.1 Field Observations and PID Measurements ? As the USTs were excavated, soil vapor samples were collected and screened with an HNU Model 101 PID equipped with a 102 eV lamp and calibrated for direct readings in parts per ? million (ppm) volumeJvolume of benzene. The soil vapor samples were analyzed using jar headspace analysis in accordance with MPCA guidelines. According to MPCA guidance ? documents, PID measurements above background (0.0 ppm) in the soils surrounding the fuel oil tanks are considered contaminated. ? PID readings ranged from 1.5 to 40 .ppm during the excavation of UST 1, 1.0 to 30 ppm ? during the excavation of UST 2, and 0.0 to 300 ppm during the removal of the associated ? piping. The highest readings were recorded in soils azound the fill pipe of USTs 1 and 2 and below the associated pipe lines. The soil vapor sample locations aze shown in Figure 5, and ? the PID readings from azeas within the excavations and along the pipe line trench aze presented in the MPCA's Excavation Report form in Appendix A. ? 7 I ? The two 19,000-gallon heating oil USTs were cathodically protected and coated steel tanks. ? Both tanks were in good condition with no visible holes or pitting noted during excavation and removal. The backfill material within the UST 1 and 2 basins consisted of silty sand, ? and the native soil within both basins consisted of a sandy clay. The dimensions of the two excavations were as follows: the UST 1 basin was approximately 50 feet long by 29 feet ? wide by 16.5 feet deep; and the UST 2 basin was approximately 37 feet long by 22 feet wide by 15 feet deep. The limits of the excavations aze shown in Figure 3. A total of ? approximately 75 cubic yards of contaminated soil was removed from the UST 1 and 2 basins and along the pipe lines. ? 3.1.2 Analytical Results ? After excavation of the tanks, piping, and contaminated soil was completed the following ? eleven (11) soil samples were collected to represent the final extent of the excavation: two from the bottom of the UST 1 basin, SS-8 and SS-9, four from the sidewalls of the UST 1 ? basin, SS-1, SS-6, SS-7, and SS-10, two from the bottom of the UST 2 basin, SS-11 and SS- 17, and three from beneath the associated piping, P-1, P-2, and P-3. All samples were ? submitted to the laboratory for analysis for BETX, and TH as fuel oil. Soil sample locations are presented in Figure 5. This information is also presented in the MPCA's Excavation ? Report in Appendix A. ? Analysis of the samples detected low levels of petroleum constituents. Benzene was detected at 0.010 ppm in samples P-1 and P-3, collected from beneath the piping at 7 feet below , ground surface. The analytical results of the remaining samples were below method detection limits. ? ? In addition, three soil samples, SP-1, SP-2, and SS-19, were collected from stockpiled soil and submitted to the laboratory for analysis for BETX and TH as fuel oil. TH as #2 fuel oil ? was detected at 3 ppm in stockpile sample SP-2. 1 8 I I I ' , , APPENDIX A I EXCAVATION REPORT FOR PETROLEUM RELEASE STTES , I I I ' , a 1 Fl, 1 1 t 1 I r EXCAVATION REPORT FOR PETROLEUM RELEASE SITES ' Minnesota Pollution Control Agency Tank and Spills Section May 1991 r The information below should be completed and submitted to the Minnesota Pollution Control Agency (MPCA) Tanks . and Spills Section to document excavation of peuoleum contaminated soil.
