EPA said its decision to extend the comment period was the result of requests made by several organizations for additional time. Many of the requests focused on previously deferred tanks, including wastewater treatment tanks and airport hydrant systems at commercial airports, and the need to understand the potential impacts of the proposal on these systems.
Stakeholders also requested additional time to review PEI’s Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities (PEI/RP1200). PEI’s RP1200 is available for download and public comment through March 26.
EPA said its decision to extend the comment period another 60 days was influenced by the issues identified above and would “ensure robust public involvement.”
