EPA Region 4 On Scene Coordinator initiated an emergency response action at the Crowders Mountain State Park after discovering numerous abandoned drums during a Removal Site Evaluation. Orphaned drums, containing product, are scattered about the site. Drums are in poor, dilapidated condition, unidentifiable or without legible makings. Located on the two-acre site are several open excavation pits and three stockpiles of soil/crushed drums & debris with contamination that tested as RCRA Hazardous or above TCLP concentrations for lead and VOCs.
Residential properties and a creek border the site. The OSC documented that erosion and sedimentation countermeasures were not in place. Organic vapors were identified in the ambient air throughout site. Source contamination was tentatively identified as miscellaneous paint/lacquers/organic solvents.
ERRS and START contractors were mobilized on 9/16/09 to support the response efforts.
ERRS completed treatment, off-site shipment, and disposal of the three stockpiles (measureing approximately 1800 cu yards) of contaminated soil with triple superphosphate (TSP) (2.5% Fe + 1% P-TSP) fertilizer to stabilize lead and VOCs to below TCLP and Land Band concentration levels. 43 off-site shipments to a Subtitle-D landfill took place on November 6,7 and 9, 2009.
EPA Science and Ecosystems Division (SESD) completed a geophysical survey using a magnetometer on November 17, 2009 and composed a map that identifies potential locations of the remaining buried stockpiles of drums.
Contract support by ERRS and START have demobed from the site pending approval to amend funding through a Ceiling Increase Action Memorandum..
Security will remain on site through the end of the year and the first week of 2010.
Removal work will recommence pending additional funding approval.
None at this time.
