1 Thresholds for point source determination shown in tons per year of potential to emit as defined in 40 CFR part 70, with the exception of lead. Reported emissions should be in actual tons emitted for the required time period.

2 Type A sources are a subset of the Type B sources and are the larger emitting sources by pollutant.

3 NAA = Nonattainment Area. The point source reporting thresholds vary by attainment status for SO2, VOC, NOX, CO, PM10, PM2.5, and NH3.

Title 40 published on 2015-08-22

The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 40 CFR Part 51 after this date.

  • 2017-01-17; vol. 82 # 10 - Tuesday, January 17, 2017

      ENVIRONMENTAL PROTECTION AGENCY
      Final rule.
      This rule is effective February 16, 2017. For all regulatory applications covered under the Guideline, except for transportation conformity, the changes to the appendix A preferred models and revisions to the requirements and recommendations of the Guideline must be integrated into the regulatory processes of respective reviewing authorities and followed by applicants by no later than January 17, 2018. During the 1-year period following promulgation, protocols for modeling analyses based on the 2005 version of the Guideline, which are submitted in a timely manner, may be approved at the discretion of the appropriate reviewing authority. This final rule also starts a 3-year transition period that ends on January 17, 2020 for transportation conformity purposes. Any refined analyses that are started before the end of this 3-year period, with a preferred appendix A model based on the 2005 version of the Guideline, can be completed after the end of the transition period, similar to implementation of the transportation conformity grace period for new emissions models. See the discussion in section IV.A.4 of this preamble for details on how this transition period will be implemented. All applicants are encouraged to consult with their respective reviewing authority as soon as possible to assure acceptance of their modeling protocols and/or modeling demonstration during either of these periods.
