10 CSR 10-6.261 Control of Sulfur Dioxide Emissions

This new rule will set enforceable environmental conditions and emission limits necessary to address the U.S. Environmental Protection Agency’s 1-hour sulfur dioxide (SO2) National Ambient Air Quality Standard (NAAQS) of 75 parts per billion (ppb) [75 Federal Register (FR) 35520, June 22, 2010]. The rule is a core component of the Missouri State Implementation Plan (SIP) for the SO2 nonattainment area in Jackson county. In addition, this proposed rule incorporates all necessary existing provisions from 10 CSR 10-6.260 Restriction of Emission of Sulfur Compounds (i.e., provisions in place prior to the 1-hour SO2 NAAQS) in order to consolidate SO2 requirements and reduce confusion for Missouri’s SO2 emission sources.

10 CSR 10-6.260 Restriction of Emission of Sulfur Compounds

This rulemaking will rescind the current rule. The department’s Air Pollution Control Program is proposing a new sulfur dioxide (SO2) rule, 10 CSR 10-6.261 Control of Sulfur Dioxide Emissions, that addresses requirements for sources affected by the U.S. Environmental Protection Agency's initial 1-hr SO2 National Ambient Air Quality Standard nonattainment designations.  That new rule also carries forward requirements as is from 10 CSR 10-6.260 needed to maintain existing levels of SO2 control in areas outside nonattainment areas.
