2060-AQ18 201004 Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Air and Radiation AR 2000 Environmental Protection Agency EPA Technical Amendments for Marine Spark-Ignition Engines and Vessels In the final rulemaking for new exhaust and evaporative emissions standards for nonroad spark-ignition engines, vessels, and equipment (73 FR 59034, Oct. 8, 2008), EPA established first-ever evaporative emissions standards for marine vessels. For one small subset of marine fuel tanks (portable tanks), further evaluation of the design standard for diurnal emissions has raised a concern that fuel spillage may occur under certain circumstances. We have engaged the industry to identify a simple, safe, and emissions-neutral solution to this issue. The purpose of this action is to make technical amendments to the design standard for portable tanks that will allow for this solution. In addition, we also intend to incorporate safe recommended practices, developed through industry consensus, for portable marine fuel tanks.
