Notice of Public Hearing and Comment Period on Air Quality Issues - State Implementation Plan

Friday, July 20, 2018

Notice is hereby given that a public hearing will be held on Monday, August 20, 2018, at 5:30 p.m. in Room 555 at 1200 First Street NE, 5th Floor, in Washington, D.C. 20002. This hearing provides interested parties an opportunity to comment on the proposed revision to the District of Columbia’s (District) State Implementation Plan (SIP), found at 40 C.F.R. Part 52 Subpart J, regarding certain federal Clean Air Act (CAA) requirements under Sections 110(a)(2)(A) to (M). Once the District has completed its procedures, the proposed revision to the SIP will be submitted to the EPA for approval.

The U.S. Environmental Protection Agency (EPA) promulgated revisions to the national ambient air quality standards (NAAQS) for 8-hour ozone in 2015 (80 Fed. Reg. 65,292; October 26, 2015). The District was designated as marginal nonattainment for the 2015 standards (83 Fed. Reg. 25,776; June 4, 2018). As per the federal Clean Air Act mandate, the District of Columbia (District) is required to prepare an Infrastructure State Implementation Plan (i-SIP) that affirms that laws and regulations are in place in the District and in the District-wide SIP to allow for adequate implementation, maintenance, and enforcement of the 2015 8-hour ozone NAAQS.

This SIP revision is a compilation of elements that describe how the District is implementing the “infrastructure” elements of the 2015 8-hour NAAQS. Once approved by EPA, it will provide a federally enforceable written confirmation of how the District will continue to comply with the §110(a)(2) requirements of the CAA for ground-level ozone.

Copies of the proposed SIP revision are available for public review during normal business hours at the offices of the Department of Energy and Environment (DOEE), 1200 First Street NE, 5th Floor, Washington, DC 20002, and attached below.

Interested parties wishing to testify at this hearing must submit in writing their names, addresses, telephone numbers and affiliation, if any, to Ms. Alexis Tinsley at the DOEE address above or at [email protected] by 4:00 p.m. on August 20, 2018. Interested parties may also submit written comments to Ms. Alexandra Catena, Monitoring and Assessment Branch, Air Quality Division, DOEE, at the same address or by email at [email protected]. Questions about this SIP revision should be directed to Mr. Rama S. Tangirala by phone at 202-535-2989 or email at [email protected], or Ms. Catena at 202-741-0862 or [email protected]. No comments will be accepted after August 20, 2018.
