Epa Vetting Naaqs Implementation Options For Future Air Act Changes

摘要

EPA is vetting a range of options that could dramatically change the way the agency implements the national ambient air quality standards (NAAQS),including delegating enforcement authority to states and eliminating the state implementation plan (SIP) system,in the lead up to offering Congress options for amending the Clean Air Act. The possible options on NAAQS implementation may come alongside the agency's planned language to amend the prohibition on considering costs when setting NAAQS-an approach sources say is stalled for lack of support.
