Problems/Comments
DEC received a spill report on 9/26/2016 noting that a contractor was replacing utility pole #8783 on 9/20/2016 and encountered some contaminated soil they believed smelled like gasoline or diesel fuel. They reported the affected area as 4' x 6'. Contaminated soil that was excavated for replacement of the pole was stockpiled on site. One soil sample was taken from the soil stockpile from a depth of 6-inches. The sample was analyzed for gasoline range organics, diesel range organics (DRO), residual range organics, volatile organic compounds, polycyclic aromatic hydrocarbons, total metals, and polychlorinated biphenyls. DRO, chromium, and arsenic were confirmed above DEC cleanup levels. Transport of the contaminated soil was approved to ASR for remediation. No sampling was done to characterize the excavation limits and it was reported that the excavation was backfilled. Further characterization may be required.

| 2/21/2020 | Update or Other Action | Site Characterization Report received. Site characterization UVOST probes, soil borings, & analytical sampling results did not indicate the presence of any remaining POL contamination related to the unknown release at power pole #8783. However, the analytical results did indicate that a presence of pentachlorophenol (PCP), a known industrial wood preservative, has occurred &/or is occurring, because this site is located in a powerline corridor. PCP detected at the site is not attributable to the original unknown fuel release at power pole #8783 & is likely a result of leaching from utility poles present on site. PCP is a CERCLA-regulated hazardous substance. PCP is an EPA registered pesticide (pesticide chemical number 063001) & is used industrially as a wood preservative for power line poles, cross arms, fence posts, & the like. With this site being located in a power pole corridor, PCP is not subject to liability under CERCLA because it is an EPA registered pesticide & was introduced into the environment due to its proper application & intended use as stated in the United States Code, Title 42, The Public Health & Welfare, Chapter 103, CERCLA, Subchapter I, Hazardous Substances Releases, Liability, Compensation, Section 9607, Liability (42 U.S.C 9607(i)). Additionally, the most stringent EPA Regional Screening Level [November 2019], target cancer risk of 1 x 10-6 with a target hazard quotient of 1.0 (because there is only one contaminant of concern [COC] at the site), Resident Soil for PCP is 1.0 mg/kg. All detected concentrations of PCP are below this value. [Generally, if you are screening only one contaminant, the THQ=1.0 table can be used. Generally, if you are screening multiple chemicals it is preferred, to use the THQ=0.1 tables. The rationale for using THQ=0.1 for screening is that when multiple contaminants of concern are present at a site or one or more are present in multiple exposure media, the total hazard index could exceed 1.0 if each were screened at the HQ of 1.0.] | Louis Howard |
