A Phase I Environmental Site Assessment ESA previously performed for the site by Pima County, dated September 28, 2009, identified the following recognized environmental conditions RECs in connection with the site: � Equipment and vehicle maintenance was reportedly conducted at the site, predominantly inside the service bays in the southernmost structure and outside along the southern boundary of the site. The types of maintenance chemicals used and generated included oils, lubricants, gasoline, and anti-freeze. Leaks or spills may have impacted site soil in this area. Therefore, soil samples should be collected and analyzed for volatile organic compounds VOCs and polynuclear aromatic hydrocarbons PAHs. � Two sealed floor drains were observed in the southernmost structure. Maintenance chemicals may have been disposed through the floor drains and may have impacted site soils. Soil samples should be collected from beneath the floor drains and analyzed for VOCs and PAHs. Four soil samples were collected from the yard area where there may have been impacts from vehicle maintenance activities. Two samples were collected from soil located near and approximately 30 inches below the bottom of two floor drain vaults. The six soil samples were analyzed for VOCs and PAHs. No VOCs were detected in the samples. The PAHs chrysene and pyrene were detected in one sample FD-1-0.5 however, the concentrations did not exceed the applicable State of Arizona SRLs. Therefore, no additional environmental investigation or remediation of these areas is recommended.
Former Use: The subject property is located on the southwest corner of Curtis Road and Davis Avenue. Prior to 1958, two small structures were constructed in the south central portion of the property, which otherwise consisted of undeveloped native desert land. It is unknown exactly when these structures were removed, however, sometime between 1973 and 1978 the Flowing Wells Volunteer Fire Station No. 2 began to operate from this address and aerial photography from 1990 shows that the two original structures are no longer visible and that a new structure, which is still present, was constructed in the eastern portion of the property. Between 1996 and 2002 the area west of the structure was paved and equipment storage began to take place along the western and southern boundaries. Presently, the commercial structure located on the eastern portion of the subject property is utilized by the Northwest Fire District. There is paved parking to the west and south of the structure. The western portion of the property is otherwise unoccupied.
