2) The facility (122 E. Sample Street) was identified as a RCRA CESQG by the regulatory database search, with waste streams identified as Not Defined (D000), Ignitable Hazardous Wastes (D001) and Spent Non - halogenated solvents (F003). Such wastes are generally the result of mixed wastes generated by two parts washing basins containing mineral spirits. Such mineral spirits, as well as waste oils generated on site, and received from off -site, are burned within an on -site waste oil furnace. Overall, an estimated 200 - gallons of mineral spirits and 275 - gallons are burned annually by the waste oil furnace, with introduction by an aspirating (air compressor) system. The waste oil /solvent mix is stored within aboveground storage tanks that are adjoining the furnace unit. As a result of transfer operations and blow -down from the air compressor unit (aspirator), significant staining of the concrete flooring was identified in the area of the waste oil furnace. Some level of subsurface contamination may have resulted as a result of the incidental releases associated with the waste oil furnace operations (Recognized Environmental Condition). 3) Numerous floor drains were identified throughout the workshop area of the building. Although attempts had been made to "close" several of the drains, there remains some doubt as to how effective such closure was in sealing off potential entry of waste oils and other potential contaminants. Other drains remained operational and were located in areas of the building whereby the introduction of waste oils and potentially solvents (i.e., mineral spirits) was possible. The discharge point for drains is thought to be the municipal sanitary sewer (unconfirmed); however the likelihood exists that at least one of the drains (principally installed to facilitate the removal of snow melt) may discharge to the on -site dry well located within the rear parking area of the facility. Staining of the concrete in areas surrounding the floor drains was visually apparent. Based on the aforementioned factors, the floor drains and the potential introduction of waste oils and possibly solvents to the subsurface environment throughout 45 years of motor repair service, is considered a Recognized Environmental Condition. It should also be noted that the immediate area of the subject site has been the location of significant industrial activity dating to the early 1900s, and that potential sources of contamination in the immediate area of the subject site may not be fully delineated. As such, the potential exists that as yet "undiscovered or unreported" releases may be identified in the future (i.e. off -site sources). We also note that the chemical and physical characteristics of the primary Contaminant of Concern (Tetrachloroethylene) for both the Sibley Foundry and Ziker Cleaners Corrective Action Plan activities (north of site), to that of waste oils and mineral spirits identified as being associated with historical Enyart Electric Motor Repair operations, are distinctly different. Thus, the potential for on -site environmental impact as a result of material handling activities conducted at the Enyart Electric Motor Repair /Service facility cannot be discounted based solely on the groundwater date from two nearby, off -site well locations installed during assessment of Tetrachloroethylene associated with the Sibley Foundry and Ziker Cleaners. Based upon the aforementioned, PES has recommended a Phase II Environmental Site be undertaken for the purpose of assessment the extent to which, if any, the historical activities have potentially impacted the subsurface environment. Accordingly, the following sections present our approach toward conducting the Phase II Environmental Site Assessment, projected costs and a tentative schedule for completion.
