Lead Infrastructure SIP Requirements - Notice of Public Hearings and Public Comment Periods


Notice is hereby given that a public hearing will be held on Monday, March 11, 2013, 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 United States Environmental Protection Agency (EPA) for approval.

This SIP revision is a compilation of elements that describe how the District is implementing the “infrastructure” elements of the 2008 lead (Pb) national ambient air quality standards (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 Pb.

This SIP revision is being proposed simultaneously with a SIP revision to replace the District’s conflict of interest provisions to meet the requirements of the CAA for all criteria pollutant NAAQS, not just the Pb NAAQS.

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

Interested parties wishing to testify at this hearing must submit in writing their names, addresses, telephone numbers and affiliation, if any, to Mr. William Bolden at the DDOE address above or at by 4:00 p.m. on March 11, 2013. Interested parties may also submit written comments to Ms. Jessica Daniels, Monitoring and Assessment Branch, Air Quality Division, DDOE, at the same address or by email at Questions about this SIP revision should be directed to Mr. Rama S. Tangirala by phone at 202-535-2989 or email at, or Ms. Daniels at 202-741-0862 or No comments will be accepted after March 11, 2013.
