The Environmental Protection Agency (EPA) is proposing to amend the National Emission Standards for Hazardous Air Pollutants (NESHAP) from Hazardous Waste Combustors (HWC) to remove the exemptions and revise other provisions associated with emission standard exemptions for periods of malfunction, to add electronic reporting provisions, to amend emergency safety vent provisions, and to correct other minor provisions. The removal of the exemption for periods of malfunction is predicated on the previous vacatur of emission standard exemptions for periods of startup, shutdown, and malfunction (SSM) from the applicable general provisions. We are also proposing to remove or revise some associated requirements that are unnecessary, inappropriate, or redundant in the absence of the malfunction exemption, such as in recordkeeping and reporting. Emission standards will apply during periods of malfunction as required under the Clean Air Act (CAA). The addition of electronic reporting provisions will provide for simplified reporting by sources and will enhance the availability of data on sources to the EPA and the public. In addition, the EPA is proposing amendments to emergency safety vent provisions and one correction to the rule to correct an inadvertent error in the Code of Federal Regulations (CFR) related to the use of Method 23 to determine compliance with the dioxin and furan standards.
