New York Metropolitan Area Carbon Monoxide SIP Revision Proposal

The following is the content of a letter and associated attachments sent to the Regional Administrator at the USEPA, Region 2, Judith A. Enck. The letter was signed on October 5, 2012 by Joseph J. Martens, Commissioner. Items mentioned in the letter, but not made available on the website, are available upon request.

This letter is in response to the United States Environmental Protection Agency's (EPA) July 26, 2007 request for additional information pertaining to the New York State Department of Environmental Conservation's (DEC) carbon monoxide (CO) state implementation plan (SIP) revision submitted on April 5, 2007. The SIP revision clarifies the commitments identified in DEC's November 15, 1992 submittal entitled "Carbon Monoxide Attainment Demonstration - New York Metropolitan Area".

DEC wishes to move forward with the SIP revision at this time and hereby submits the July 17, 2007 public hearing records and the DEC's response to comments received during the public comment period. DEC is also submitting monitoring data for 2007 through 2011 that demonstrates continued compliance with the national ambient air quality standard (NAAQS) for CO. The current design value for CO (2010-2011) is 1.8 parts per million (ppm), which is lower than the 2.5 ppm design value at the time of the 2007 submittal, and well below the NAAQS of 9 ppm (9.4 ppm monitored due to rounding).

I've also enclosed the April 5, 2007 CO SIP revision clarifying the commitments identified in DEC's November 15, 1992 "Carbon Monoxide Attainment Demonstration - New York Metropolitan Area" and EPA's July 26, 2007 request for additional information.

We look forward to EPA's expeditious approval of this SIP revision.

Please call me at (518) 402-8540 if you have any questions.
