MODIFIED CORRECTIVE ACTION PLAN (COST PROPOSAL NO. 40) FOR DART MART, HIGHWAY 43 AND JOHNSTON ROAD, MCINTOSH, ALABAMA
Alabama Department of Environmental Management (ADEM), 240 pp, 2017

ADEM requires the implementation of a Corrective Action Plan for remediation of soil and groundwater affected by BTEX, naphthalene, and MTBE after releases of unleaded gasoline from an underground storage tank located at the subject site. This document provides a summary of environmental activities conducted to date at the facility and a detailed description of the proposed methods of site cleanup. Free-product recovery via mobile enhanced multi-phase extraction was conducted in 2003, 2007, and at irregular intervals from 2013-2016. In the modified plan, the first phase of corrective action consists of ozone sparge techniques to provide COC mass reduction. The second phase, natural attenuation, is to commence when contaminant concentrations are at or near the site-specific corrective action limits but do not warrant further ozone sparge efforts. http://www.adem.state.al.us/newsEvents/notices/nov17/pdfs/11dartmart.pdf
