The focus of the Energy Policy Act of 2005 was leak prevention and included a provision for States to annually report the sources and causes of UST releases. The average percentage of unknown release sources was approximately 40% and the average percentage of unknown release causes was approximately 60% based on most recent available EPA Public Record reports posted on State websites.
The ASTSWMO Tanks Subcommittee is hosting this webinar to discuss the currently available source and cause information nationally, the impacts of source and cause at the State level, and corrosion/degradation related issues internally and externally for UST systems. The webinar will also present a State example of how we can document source and cause more thoroughly for future national leak prevention analysis efforts.
Alex Hall (EPA ORD) will discuss his analysis of the EPA National Database for UST and LUST. His analysis includes a review of specific States’ data looking at causes of releases, tank construction, tank age, and some broad national trends.
Therron Blatter (UT DEQ) will discuss their analysis on source and cause of releases covered by Utah’s Petroleum Storage Tank (PST) Fund, which includes an evaluation of cleanup costs and release discovery method and key points for data collection in their evaluation of source and cause impacts.
Chris Marks (AZ DEQ) will discuss corrosion and degradation that has been observed internally and externally in UST systems in relationship to source and cause.
Zach Barrett (FL DEP) will discuss Florida’s process for determining and recording release source and cause information, which has helped decrease their percentage rate of unknown release source and cause information.
