Problems/Comments

Site is contaminated with petroleum and lead from broken, buried batteries. Lead failed TCLP. On September 14, 2002 APC and the FS entered into an MOU to establish a process by which APC would provide the FS with a master list of all known LTFs where APC conducted activities on National Forest Land. This site was one of those identified needing further investigation and possible cleanup.
