UNDERGROUND STORAGE TANK CLOSURE REPORT Report Date: January 10, 2011

SITE: Krawiec Residence Location: 442 South Main Street Norwich, VT 05055 Owner: Mr. Dan Krawiec Harper Env. Project Mgr.: Cliff Harper, P.G.

SCOPE OF WORK On January 7, 2011, the closure by removal of one 275-gallon fuel oil UST and removal of the vent and fill line was completed. Inspection of the UST, excavated tank pit soils, and soil screening inside excavation was performed by Harper Environmental. A report of soil conditions and UST condition was presented to the owner. Determined a minor release of fuel oil into soils associated with one 275 -gallon UST. Tank cradle/soil screening had readings using a PID, and visual impact to the soil was noted.

PROJECT NARRATIVE Date Completed: The 275-gallon UST was uncovered on January 7, 2011. Harper Environmental Associates (HEA) conducted the tank pit inspection, and cut and cleaned the tank on January 7, 2011. Location of UST: The 275-gallon UST was located along the front of the house; to the right of the front door walkway. The centerline of the UST was parallel to the foundation wall and in contact with the foundation wall. The top of the UST was located approximately one foot below grade and the base of the tank was approximately four feet below grade. The location of the UST can be seen on the site sketch.

Surrounding Land Use: Rural residential property with surrounding residential/farm land use. Geology/ Hydrogeology: Soil consisted of brown fine to medium silt with gravel and cobbles. No groundwater was encountered in the tank pit and all soils appeared dry with no indication of seasonal high water table. No bedrock was encountered during the completion of the excavation. Contaminant Investigation Results: Inspected all soils from the excavation with a PID. PID readings from the bottom of the tank pit were 30 ppm. At four feet below grade PID readings were ~140 ppm. At a depth of ~ 7 feet, PID readings were 4.8 ppm. Approximately 1.5 cubic yards of soil was removed from beneath the tank until PID readings were below 5 ppm. The pit was backfilled with clean fill and the site leveled. The tank was taken offsite and recycled for scrap metal. Analytical Lab Results: One confirmatory soil sample from approximately 7 feet below grade was sent to Phoenix Environmental Laboratories on January 10, 2011 to be analyzed by EPA Methods 8015 B and 5035 (VOCs in soil). The results from the laboratory showed no exceedances of EPA Regional Screening Levels. Table 1 provides a summary of the analytical data.

Reason for Closure: Residence converted to an above-ground storage tank in the basement. UST Size/Contents/Age/Condition: 275-gallon/fuel oil/~25+ years/poor condition. HEA arrived on site January 7, 2010. Upon arrival, the tank had already been pumped out, leaving ~2 inches of sludge in the bottom of the tank. The tank was uncovered and removed from the tank pit. Soil beneath the tank was screened and found to have positive PID readings. See attached photos. Initial Site Characterization:

Sensitive Receptor Discussion: Soil: Soils surrounding the UST were checked for readings with a PID. Results were 30 ppm directly below the tank. Approximately five feet below grade PID readings were 140 ppm. At seven feet below grade PID readings were down to 4.8 ppm. Groundwater: No groundwater was encountered in the tank pit. Surface water: None proximate to the site. Drinking water: Residence uses Town of Norwich, VT public water supply. Living Spaces: Basement located next to UST. Indoor air was screened on the day of UST removal activities, 0 ppm throughout house. Conclusions/Recommendations: Due to the post-excavation soil sample results suggesting no remaining contamination in the former UST pit, we believe the bulk of contaminated soil (~1.5 cubic yards) was removed on January 7, 2011 during UST removal activities. We suggest disposing of the contaminated soil, and we recommend closing this site based on the removal of the bulk of the release.
