The Association of State and Territorial Solid Waste Management Officials (ASTSWMO) Hazardous Waste Subcommittee respectfully requests a 60-day extension of the comment period for the Environmental Protection Agency’s (EPA) supplemental proposal to revise the definition of solid waste (DSW) rule. The current 60-day comment period is insufficient to allow full analysis and debate among State waste managers, and so we are formally requesting an extension. The extended comment period would end November 29, 2011. EPA has committed to publishing a final rule by December 31, 2012. Therefore, granting a 60-day extension will still allow EPA plenty of time to review comments and publish a final rule.
