By 1906 an additional dwelling was present on the northeast corner of the Site. The 1950 Sanborn Map shows a filling station on the front(east side) of the subject site and by 1957 a car wash was added behind the filling station. The area was, and is, primarily residential housing. The dwelling on the rear (west side) of the Site was removed by 1965 and an addition to the garage was noted in the 1970 map. Although it is still listed as a filling station and a car wash,gasoline sales ceased by 1970 and the facility closed by 1980. In 1984 the operation had changed to Magic Muffler Company which performed muffler installation,tire sales, and car repairs until the building was demolished for redevelopment in 2018. A site inspection was conducted by Bruce Poole, Environmental Scientist for SP Engineering, Inc. on May 2, 2018 to identify visual evidence of Recognized Environmental Conditions (RECs). The subsurface assessment activities resulted in the detection of ash-containing soil in Boring TB-5 that is located in the rear of the lot. Petroleum-containing soil also was detected in the gasoline underground storage tank when the UST was removed. Remediation included the excavation of metals-containing soil from the former house foundation adjacent to Cross Street, and petroleum-containing soil from the UST grave adjacent to Bridge Street. Approximately 300 tons of material that included ash, brick, and soil were excavated from the vicinity of the former residential building. The material was transported to the Aggregate Recycling Facility in Eliot, ME. Approximately 342 tons of fill material was brought to the Site on September 14 and 17, 2018 from 9 South Mason Street, Salem, MA under a Material Shipping Record to backfill the house foundation. The petroleum-containing soil (approximately 100 cubic yards) that was excavated from the UST grave was transported to the Aggregate Recycling Facility in Eliot, ME. During demolition of the Magic Muffler building in March 2019, several partially filled waste oil drums, buckets, and unopened containers were discovered in a small rear room that were overlooked prior to demolition. During demolition activities MassDEP issued a Release Tracking Number (3-34585) due to the potential for a Threat of Release to the soil. During demolition site equipment was moving a 10-inch snowfall when the operator encountered the drum storage area, overturning a five-gallon, partially filled, original container of pink transmission fluid and some waste oil in a bucket. The material was contained, containerized, characterized, and transported to Stericycle in Chicago, IL. A Method 1 Risk Characterization assessed the risk of harm to human health, public welfare, safety, and the environment using site-specific data, current and potential future uses of the site,and recommended MassDEP risk characterization guidance. The risk assessment concluded that a condition of No Significant Risk of harm to health exists for both current and foreseeable uses.
