Air Plan Approval; WA; Infrastructure Requirements for the 2010 Sulfur Dioxide and 2015 Ozone Standards; Availability of Supplemental Information and Reopening of the Comment Period

Whenever a new or revised National Ambient Air Quality Standard (NAAQS) is promulgated, the Clean Air Act (CAA) requires states to submit a plan for the implementation, maintenance, and enforcement of the standard, commonly referred to as infrastructure requirements. On May 26, 2020, the Environmental Protection Agency (EPA) published a notice of proposed rulemaking to approve the Washington State Implementation Plan as meeting specific infrastructure requirements for the 2010 sulfur dioxide (SO 2 ) and 2015 ozone NAAQS. Due to an administrative error, the technical support document was left out of the docket during the initial comment period from May 26, 2020 to June 25, 2020. Thus, the EPA is providing an additional 30 days for public comment on the proposed action. We are also supplementing the docket with additional supporting materials in response to a comment on our proposed approval.
