The EPA promulgated the NSPS for the secondary lead smelting source category (40 CFR part 60, subpart L) on March 8, 1974. Subpart L as promulgated in 1974 regulates particulate matter (PM) emissions from blast and reverberatory furnaces and also specifies limits for visible emissions (opacity) for blast, reverberatory, and pot (refining) furnaces. The EPA amended Subpart L on October 10, 1975, to remove a provision providing that the failure to meet the NSPS emissions limits due to the presence of uncombined water in the stack gases was not considered a violation. Currently, there are 11 secondary lead smelting facilities in the United States and each facility operates furnaces that are subject to the PM and opacity limits specified in Subpart L.
Section 111 of the Clean Air Act (CAA) requires the EPA to review the NSPS at least every 8 years and to revise the standards of performance that are applicable to new, modified, and reconstructed sources, if appropriate, to reflect the best system of emissions reduction (BSER), accounting for the cost, environmental, and energy impacts associated with achieving the reduction. Based on the CAA Section 111 review of the NSPS for the secondary lead smelting source category, in the recent 2022 action the EPA proposed updates to Subpart L including revisions to the applicability dates and proposed revisions to the definitions of blast furnace, reverberatory furnace, and pot furnace to more closely align with the equipment definitions used in the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for secondary lead smelting (40 CFR part 63, Subpart X). Additionally, the EPA proposed requirements for periodic performance tests for PM and incorporated the monitoring, recordkeeping, and reporting requirements, including electronic reporting of performance tests, specified in NESHAP Subpart X to improve the consistency between the NSPS and NESHAP for secondary lead smelting facilities. This information is being collected to assure compliance with 40 CFR Part 60, Subpart L.
In general, all NSPS standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance and are required of all affected facilities subject to NSPS.
The increase in burden from the most recently approved ICR is due to program changes. The proposed updates to Subpart L include requirements to conduct periodic performance tests for PM, which results in an increase in the overall burden hours and costs.
