Air Plan Approval; California; Feather River Air Quality Management District

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Feather River Air Quality Management District (FRAQMD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns emissions of volatile organic compounds (VOCs) from surface preparation and clean-up operations. We are proposing to approve a local rule to regulate these emission sources under the Clean Air Act (CAA or the ``Act''). We are taking comments on this proposal and plan to follow with a final action.

National Emission Standards for Hazardous Air Pollutants: Carbon Black Production Residual Risk and Technology Review and Carbon Black Production Area Sources Technology Review

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Carbon Black Production major source category. The proposal addresses the results of the residual risk and technology review (RTR) for this source category as required under the Clean Air Act (CAA). The proposed amendments address hazardous air pollutant (HAP) emissions that occur after the main unit filter of a carbon black production unit, as well as emissions from boilers and process heaters.
