The EPA published final revisions in the Federal Register to 40 CFR Part 63, Subpart AAAAA, National Emissions Standards for Hazardous Air Pollutants for Lime Manufacturing Plants in late July with changes impacting several key sections.
The latest update — which is not effective until January 20, 2021 — does not include any revisions based on EPA’s Risk and Technology Review (RTR). However, the final revisions included amendments to the startup, shutdown, and malfunction (SSM) provisions. Included in those changes are a revised definition for startup and established opacity limits (reference Table 2) of Subpart 5A during startup and shutdown for kilns and coolers equipped with a baghouse or electrostatic precipitator (ESP). A copy of the final rule is available here.
New Electronic Reporting Requirements
The final rule from the EPA also included changes to electronic reporting requirements. Sources impacted by the change are required to report electronic copies of performance tests, performance evaluation tests, and semiannual compliance reports via EPA’s Central Data Exchange (CDX) using the Compliance and Emissions Data Reporting Interface (CEDRI).
The Semiannual Compliance Report must be submitted using a CEDRI Excel spreadsheet entitled “63.7131(g) Semiannual Compliance Report.” A copy of this report template is available here for download. For the reporting period January 1 – June 30, Semiannual Compliance Reports are due no later than July 20. For the reporting period of July 1- December 31, reports are due January 30.
Performance test data (e.g., Method 5 particulate test data) must be submitted no later than 60 days after the date of completing each performance test. The data must be submitted in a file format generated through EPA’s Electronic Reporting Tool (ERT).
