4.2.8 Pits. Ponds, and Lagoons A pond on the east side of the subject property collects stormwater runoff from the parking areas and roofs. The water quality in the pond appeared to be poor, with heavy algae growth, however,this observation does not constitute a Recognized Environmental Condition on the subject property. As discussed in Section 4.2.6, an evaporation pit for truck wash waste water is located west of Building F. The evaporation pit is constructed of asphalt with a plastic liner, approximately 25 by 25 feet square. Because the pond was full,the integrity of the liner and asphalt pit could not be evaluated; however, observations of plants growing through the liner in previous environmental assessments indicate that the liner is not impermeable. 4.2.9 Hydraulic Equipment Hydraulic presses were utilized in several of the buildings. The equipment appeared to be in good condition with no indication of leaks or stains. 4.2.10 Other Physical Evidence of Contamination Surface soils impacted by paint were observed to the east of Building C. American Modular Systems has provided a Product Data Sheet for the Aquatek 50 Series red oxide waterborne primer that is used for spray painting outside of Building C. Although the paint is water-based, it contains 206 g/L(or 1.72 lb/gal)of volatile organic compounds(VOCs),including glycol ether and sec-butyl alcohol. Glycol ether(also known as 2-ethoxyethanol)and butyl alcohol (also known as 1-butanol) are toxic chemicals subject to the reporting requirements of SARA Title III. The Environmental Protection Agency (EPA) Region IX has established Preliminary Remediation Goals (DRGs), or cleanup levels, for these chemicals in soil. The residential PRGs are 26,000 parts per million(ppm) for glycol ether and 6,500 ppm for butyl alcohol. Groundwater quality standards are not available for these compounds. Due to the volatility of these chemicals, it appears unlikely that soil concentrations would exceed the PRGs except perhaps in the surface paint layer. However, the historical use of spray paints and thinners of chemical composition that is different than Aquatek 50 Series cannot be ruled out. The composition of paints and thinners used in the past at this location presents a concern, as these materials may have contained mineral spirits, volatile organic compounds, and metals. 4.2.11 Asbestos and Lead Paint Based on the age of the buildings, asbestos-containing materials are not likely to be found. In addition, as metal framed buildings, the use of potential asbestos-containing material appeared R:\MN\98)CM.013 13 DAMES&MOORE
