The Department of Environmental Conservation seeks public comment on proposed amendments to §227-2, Reasonably Available Control Technology for Oxides of Nitrogen (NOx); Subpart 201-3, Exempt & Trivial activities; and Part 200, General Provisions. The changes would lower the NOx RACT emission limits for very large boilers, large boilers, mid-size boilers, and small boilers, and require a case-by-case RACT analysis for combined cycle/cogeneration combustion turbines. Comments are due February 17, 2010. http://www.dec.ny.gov/regulations/60842.html.
