National Emission Standards for Hazardous Air Pollutant Emissions: Group I Polymers and Resins (Polysulfide Rubber Production, Ethylene Propylene Rubber Production, Butyl Rubber Production, Neoprene Production); National Emission Standards for Hazardous Air Pollutants for Epoxy Resins Production and Non-Nylon Polyamides Production; National Emission Standards for Hazardous Air Pollutants for Source Categories: Generic Maximum Achievable Control Technology Standards (Acetal Resins Production and Hydrogen Fluoride Production) (Risk and Technology Review)

This final rule responds to public comments received on the proposed rule and announces our decision not to revise four national emission standards for hazardous air pollutants that regulate eight industrial source categories evaluated in our risk and technology review. The four national emission standards and eight industrial source categories are: National Emissions Standards for Hazardous Air Pollutant Emissions: Group I Polymers and Resins (Polysulfide Rubber Production, Ethylene Propylene Rubber Production, Butyl Rubber Production, and Neoprene Rubber Production); National Emission Standards for Hazardous Air Pollutants for Epoxy Resins Production and Non-nylon Polyamides Production; National Emission Standards for Hazardous Air Pollutants for Acetal Resins Production and National Emission Standards for Hazardous Air Pollutants for Hydrogen Fluoride Production. The underlying national emission standards that were reviewed in this action limit and control hazardous air pollutants. On December 12, 2007, we proposed not to revise the national emission standards based on our residual risk assessment and technology review. After conducting risk and technology reviews, and after considering public comments on the proposed rule, we conclude no additional control requirements are warranted under section 112(f)(2) or 112(d)(6) of the Clean Air Act at this time.
The Treatment of Data Influenced by Exceptional Events (Exceptional Event Rule): Revised Exceptional Event Data Flagging Submittal and Documentation Schedule To Support Initial Area Designations for the 2008 Ozone NAAQS

Agency: Environmental Protection Agency
The EPA issued ``The Treatment of Data Influenced by Exceptional Events (Exceptional Event Rule): Revised Exceptional Event Data Flagging Submittal and Documentation Schedule for Monitoring Data Used in Designations for the 2008 Ozone NAAQS'' as a direct final rule on October 6, 2008, 73 FR 58042. Because EPA received an adverse comment, we are withdrawing the direct final rule amendments to ``The Treatment of Data Influenced by Exceptional Events (Exceptional Event Rule): Revised Exceptional Event Data Flagging Submittal and Documentation Schedule to Support Initial Area Designations for the 2008 Ozone NAAQS'' published in the Federal Register on October 6, 2008 (73 FR 58042).
