2019-14473: National Emission Standards for Hazardous Air Pollutants: Municipal Solid Waste Landfills Residual Risk and Technology Review

Summary

The U.S Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP): Municipal Solid Waste (MSW) Landfills source category. The EPA is proposing decisions concerning the residual risk and technology review (RTR). The EPA is also proposing amendments to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM); revise wellhead operational standards and corrective action to improve effectiveness and provide compliance flexibility; reorganize rule text to incorporate provisions from the new source performance standards (NSPS) within this subpart; and add requirements for electronic reporting of performance test results. The EPA is also proposing minor changes to the MSW Landfills NSPS and Emission Guidelines and Compliance Times for MSW Landfills. Specifically, the EPA is proposing to add provisions to the most recent MSW Landfills NSPS and Emission Guidelines (EG) that would allow affected sources to demonstrate compliance with landfill gas control, operating, monitoring, recordkeeping, and reporting requirements of the most recent NSPS and EG by following the corresponding requirements in the MSW Landfills NESHAP.
