The Phase I Environmental Site Assessment revealed the presence of the following recognized environmental conditions in connection with the property: � Stained soil was observed in and around waste piles that were observed to contain apparent chemical containers, oil totes, automobile parts, and construction and demolition debris. Samples should be collected from the soil immediately surrounding the waste piles at four locations and analyzed for polynuclear aromatic hydrocarbons PAHs, 8 RCRA metals, and volatile organic compounds VOCs to identify potential impacts, if any, to soil and/or groundwater on the subject property. � Stained soil and petroleum-like odors were detected along the south-central area of the property, likely due to runoff from the used oil aboveground storage tank AST and air compressor located on the adjacent Kord�s Auto Care facility. Samples should be collected from the area where stained soil is observed and analyzed for PAHs and VOCs to identify potential impacts, if any, to soil and/or groundwater on the subject property. � Telephone poles and railroad ties were stored in the northwestern portion of the subject property. Telephone poles and railroad ties were historically treated with wood-preservative chemicals such as creosote and arsenic and these chemicals could leach from the telephone poles and railroad ties onto the property soil. Samples should be collected from the soil underlying and surrounding the telephone poles and railroad ties and analyzed for semi-volatile organic compounds SVOCs and 8 RCRA metals to identify potential impacts, if any, to soil and/or groundwater on the subject property. � Historical records, interviews, and site reconnaissance indicate that the subject property was formerly a used car sales dealership, the historical practices of which are a potential source of soil and/or groundwater contamination. Random samples should be collected from the subject property and analyzed for PAHs, VOCs, and 8 RCRA metals to identify potential impacts, if any, to soil and/or groundwater on the subject property. � The Lead-Based Paint LBP Inspection of the wooden storage structure located in the northwest portion of the subject property revealed the presence of LBP within the structure. The structure was placed on slightly elevated supports when it was relocated to the subject property. Because of the weatherized condition of the LBP paint on portions of the interior of the structure and evidence of water damage that would allow weatherized LBP to migrate to the soil beneath the structure, Soil samples should be collected along the drip line and perimeter of the structure and analyzed for lead. � Two 55-gallon drums and stained soil underlying and surrounding the drums were observed north of the wooden storage structure. The drums should be properly characterized and disposed and samples be collected from the soil underlying and surrounding the drums and analyzed for PAHs, VOCs, and 8 RCRA metals to identify potential impacts, if any, to soil and/or groundwater on the subject property.
Former Use: The subject property consists of two parcels 401-07-0370 and 401-07-0380 located at 2140 N. Ajo-Gila Bend Highway in Ajo, Pima County, Arizona. Interviews indicate that the storage structure located in the northwest portion of the subject property was relocated there from Mexican Town in the 1960s. In 1975, the subject property consisted of native desert with the exception of the structure located in the northwest portion. The uses on the subject property remained unchanged until at least 1996. Between 1996 and 2003, a significant number of vehicles began to be stored on the eastern portion of the subject property and along the western boundary of the subject property. Between 2003 and 2010, the number of vehicles being stored on the eastern portion of the subject property decreased however the amount of materials and equipment being stored on the northwest and north central p
