Revisions to Appendix P to 40 CFR Part 51, Concerning Minimum Emission Reporting Requirements in State Implementation Plans
Posted by [email protected] on Jul. 31, 2020
On July 15, 2020 the U.S. EPA Administrator signed a final rule amending regulations guiding the preparation of state implementation plans (SIPs). These regulations are found in 40 CFR Part 51. The final rule revises the minimum reporting frequency requirement for SIPs applicable to source categories listed in Appendix P to 40 CFR Part 51 from quarterly to semiannual (twice per year at 6-month intervals). This revision is generally consistent with the current reporting frequency requirements to which these sources are subject under other programs (e.g., New Source Performance Standards). As a result of this final rule, each state may—but is not be required to—revise its SIP to allow semiannual reporting for four source categories:
- fossil fuel-fired steam generators of more than 250 million British thermal units per hour heat input;
- fluid bed catalytic cracking unit catalyst regenerators at petroleum refineries;
- sulfuric acid plants; and
- nitric acid plants.
