1.0 INTRODUCTION AND BACKGROUND INFORMATION This Underground Storage Tank Removal and Site Assessment Report was completed by Lincoln Applied Geology, Inc. (LAG) for Mr. Peter Dartley, owner of the the underground storage tank (UST #3) located at 1615 High Pond Road in Hubbardton, Vermont (Figure 1). The UST was discovered during demolition of the former on-site residential building at 1615 High Pond Road. One 1,000-gallon heating fuel underground storage tank (UST #3) was closed in accordance with Vermont Department of Environmental Conservation (VTDEC) UST closure regulations on April 6, 2017. UST #1 was reported to be approximately 50 years old (installed in 1967). No USTs currently exist at the Site. 2.0 UST #1 CLOSURE AND SITE ASSESSMENT 2.1 Tank Removal and Cleaning

On April 6, 2017 LAG, in conjunction with McKernon Group of Brandon, Vermont performed the excavation, purging, cutting, cleaning, and Site Assessment associated with the removal of one 1,000-gallon heating fuel UST previously described in Section 1.0. The tank and associated piping was disconnected from the heating system prior to the Site visit. The cleaned UST was to be recycled by McKernon Group in Rutland, Vermont. The UST was a single wall steel tank in poor condition with significant evidence of rusting, pitting, and perforations. The associated piping was noted in fair condition. Photographs are included in Appendix A.

Approximately 450 gallons of water, residual fuel, tank bottoms, and

absorbent materials resulted from the UST cleaning process. Waste shipment and disposal will be performed by Environmental Products and Services (EP&S) and arranged by LAG.

2.2 Soil and Groundwater Evaluation

The tank cavity was visually examined for staining, discoloration,

petroleum odors, and groundwater. The excavation was approximately 20 feet long, 10 feet wide and 8 feet deep. The soil overtop and around the UST consisted of medium brown fine sand with coarse gravel. The native soils beneath the UST consisted of dense glacial till. Bedrock and groundwater were not encountered. During the UST assessment, soils were screened with a properly calibrated photoionization detector (PID) for the presence of petroleum related volatile organic compounds (VOCs).

Petroleum contamination was encountered in soils located around and

beneath the UST. VOC levels ranged from 38.7 parts per million (ppm) to 895.2 ppm. The Site Sketch presented as Figure 2 shows the soil sampling locations for PID screening. Upon discovery of a contaminant release, LAG notified the

Underground Storage Tank Removal and Site Assessment Report April 7, 2017 High Pond Property, Hubbardton, Vermont

Lincoln Applied Geology, Inc. 2

UST Program and contacted VTDEC Spill Program Member Michael Nucci to discuss measures to address the contaminated soil. Mr. Nucci instructed LAG to continue excavation with continual PID screening, and attempt to fully delineate and remove the extent of the contamination.

2.3 Soil Delineation and Removal

LAG, in conjunction with McKernon Group, was unable to fully delineate and remove the VOC contamination from the Site. During delineation, approximately 40 yards of soil was removed and screened with a PID from 0’ to 10’ below ground surface (bgs). Three test pits (TP) were installed in the south and east directions to delineate the lateral extent of contamination. PID levels ranged from 38.7 ppm to 818.8 ppm. LAG encountered significant petroleum odor and grey staining at 8-10’ bg. The vertical extent of contamination was not delineated due to dense glacial till at 10’ bg. The lateral extent of contamination was not fully delineated due to the expansive migration towards Walker Pond. Test pit TP-3 reported 38.7 ppm PID readings at 40 feet from the former UST location.

Under direction of the VTDEC, the soil removed for delineation was

backfilled into the excavation area. During site restoration, clean soils were spread over top of the contaminated soils in the excavation grave. Based on the PID data, and significant petroleum odor and staining, VOC contamination exists on site, and an initial site investigation is warranted.

2.4 Sensitive Receptor Survey During the UST removal activities LAG conducted a survey of the Site to

determine possible sensitive receptor impacts. At this time the impacted sensitive receptor is soil. Other sensitive receptors could include groundwater and Walker Pond located to the south of the site. Based on topography, groundwater is estimated to flow in a southerly direction towards Walker Pond.

3.0 CONCLUSIONS

The 1,000-gallon heating fuel oil UST and its associated piping were found to be in poor condition. The UST had significant evidence of rusting, pitting, and perforations. The UST was properly removed, cleaned and recycled. Approximately 450 gallons of water, residual fuel, tank bottoms, and absorbent materials resulted from the UST cleaning process. The UST was transported for recycling by McKernon Group. VOC contamination was encountered during the UST removal. PID readings from soil samples ranged from 38.7 to 895.2 ppm. LAG was not able to fully delineate and remove the contaminated soils. Under the direction of the VTDEC, the contaminated soils were backfilled into the UST grave. At this time, significant residual adsorbed contamination exists at the subject property. The VOC contamination from the leaking

UST could pose a risk to human health and the environment. An Initial Site Investigation regarding the closure of the 1,000-gallon heating fuel UST is warranted.
