The former Friday Oil No. 9 is an active retail petroleum and convenience store facility now known as Shell Food and Fuel West. This corrective action plan summarizes pertinent environmental activities conducted to date at the facility and provides an approach to decrease constituent of concern-BTEX, MTBE, and naphthalene-concentrations in groundwater to below site-specific corrective action levels. A schedule and cost estimates are included. A total of 4,800 gals of free product and water were pumped from the site subsurface in 2007. Mobile enhanced multiphase extraction (MEME) was also conducted, and passive skimmer devices were employed in 2007-2008. To evaluate a proposed ozone sparging remedy, three sparge wells were installed and a pilot test was conducted during the first four months of 2010, but the technology was not pursued at that time. Remediation by natural attenuation (NA) supplemented by MEME was proposed and approved by ADEM in 2015. MEME events were conducted in August and September 2016, November 2018, and February 2019. The new (2019) site contractor recommends the following combination of remedial techniques: (1) ozone sparging in areas beyond 12 ft of UST system components and underground utilities; (2) installation of ozone monitoring devices; and (3) NA monitoring to evaluate changes in groundwater chemistry. http://adem.alabama.gov/newsEvents/notices/jul19/pdfs/7friday.pdf
