Environmental Protection Agency December 3, 2020 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve through parallel processing a state implementation plan (SIP) revision submitted by the State of California to address Clean Air Act (CAA or ``Act'') requirements for the 2012 annual fine particulate matter (PM2.5) national ambient air quality standard (NAAQS or ``standard'') in the Plumas County Moderate PM2.5 nonattainment area (``Portola nonattainment area''). The submitted SIP revision is the State's ``Proposed Portola PM2.5 Plan Contingency Measure SIP Submittal'' (``Proposed PM2.5 Plan Revision''), which includes a revised City of Portola ordinance regulating PM2.5 emission sources and the State's demonstration that this submission meets the Moderate area contingency measure requirement for the 2012 annual PM2.5 NAAQS in the Portola nonattainment area. The EPA is also proposing to approve the contingency measure element of the Moderate area attainment plan for the Portola nonattainment area, as revised and supplemented by the Proposed PM2.5 Plan Revision. Because the EPA is proceeding by parallel processing, the agency is proposing, in the alternative, to disapprove the contingency measure element of the Moderate area attainment plan if the State does not submit the final, adopted PM2.5 Plan Revision in substantially the same form before we take final action.

This regulation establishes an exemption from the requirement of a tolerance for residues of Adipic acid when used as an inert ingredient in antimicrobial pesticide formulations applied to food- contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils at an end-use concentration not to exceed 100 parts per million (ppm). Ecolab, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting establishment of an exemption from the requirement of a tolerance for adipic acid. This regulation eliminates the need to establish a maximum permissible level for residues of adipic acid when used in accordance with this exemption.
