JEFFERSON CITY, MO, DEC. 1, 2009 -- The Missouri Air Conservation Commission will hold a public meeting at 9 a.m. on Dec. 3 at the Department of Natural Resources' Elm Street Conference Center, 1730 E. Elm St. in Jefferson City.

At this meeting, the commission will hear routine reports from department staff regarding air permits, operations and enforcement actions. A public hearing will also be held on several rule amendments. The commission will hear testimony on the Control of NOx Emissions from Large Stationary Internal Combustion Engines rule. This rule would amend the emission rate limitations for both large stationary diesel and dual fuel internal combustion engines to be consistent with the federal Phase II NOx State Implementation Plan Call and add a NOx exemption limit. The commission will also hear testimony on the New Source Performance Regulations, which would update the 40 CFR part 60 promulgation date to Dec. 31, 2008 and incorporate by reference six new subparts finalized between July 1, 2006 and Dec. 31, 2008.

Other amendments include the Maximum Achievable Control Technology Regulations, which would amend the 40 CFR part 63 promulgation date to Dec. 31, 2008 and incorporate by reference 22 new subparts finalized between July 1, 2006 and Dec. 31, 2008. The Emission Standards for Hazardous Air Pollutants rule amendment would update the 40 CFR part 61 promulgation date to Dec. 31, 2008; and the Ambient Air Quality Standards amendment would update the standards for ambient air quality throughout Missouri to reflect the changes in the National Ambient Air Quality Standards for particulate matter 10 microns or less, particulate matter 2.5 microns or less, ozone and lead.

The final items for public hearing will include the Reference Methods rule. This proposed amendment will update the reference methods for measuring and complying with the new NAAQS for ozone and lead. All reference methods found in 40 CFR part 50 Appendices A-R would be incorporated by reference in this rule as well as the equivalent methods found in 40 CFR part 53. The rule would then reflect the most current effective dates for the Code of Federal Regulations. The Controlling Emissions During Episodes of High Air Pollution Potential will also be presented. This proposed amendment will update the breakpoint values in Table A for the Air Quality Index. This rulemaking is necessary because when the eight-hour ozone standard was revised by EPA in March 2008 the break point values for the air quality index were also updated.

In addition, the commission will hear the comments and revisions proposed for the 2008 Lead Standard Boundary Recommendation. On Oct. 15, 2008, the U.S. Environmental Protection Agency promulgated a revision to the NAAQS for lead. Promulgation of this standard started a time clock with a deadline of October 2009 for the state of Missouri to submit a recommendation as to which areas of the state should be designated nonattainment for the new lead standard.

The Department of Natural Resources requests people intending to give verbal presentations on the proposed public hearing items also provide a written copy of their testimony to the commission secretary at the time of the public hearing. The department also will accept written comments for the record until 5 p.m. on Dec. 10. People requiring special services or accommodations to attend the hearing can make arrangements by calling 800-361-4827 or 573-751-4817. Hearing-impaired individuals may contact the program through Relay Missouri at 800-735-2966.
