NSPS for New Residential Hydronic Heaters and Forced-Air Furnaces (40 CFR part 60, subpart QQQQ) (Renewal)

The New Source Performance Standards (NSPS) for New Residential Hydronic Heaters and Forced-Air Furnaces (40 CFR Part 60, Subpart QQQQ) to new residential hydronic heaters, forced-air furnaces, or other central heaters manufactured either on or after May 15, 2015 and sold or distributed in the United States. The residential hydronic heater and forced-air furnace NSPS establishes a certification program, instead of the usual NSPS requirement that each affected facility demonstrate compliance with emission limits through performance testing. Under this certification program, a single heating appliance is tested to demonstrate compliance with particulate matter (PM) emission limits for an entire model line which could consist of thousands of stoves. The use of a certification approach significantly reduces the compliance burden, including information collection, for the manufacturers of hydronic heaters and forced-air furnaces. Each manufacturer subject to Subpart QQQQ is required to keep records of all documentation pertaining to the certification testing for each model line, the results of the quality assurance program inspections, and a sealed sample of each heater or furnace upon which certification tests were performed and certification granted. Each approved test laboratory and third-party certifier must maintain records consisting of all documentation pertaining to each certification test, quality assurance program inspection and audit test. Manufacturers must also submit the test reports and other documentation to EPA when they apply for a certificate of compliance for each model line. These reports, and records are essential in determining compliance, and are required of all affected facilities subject to NSPS. This information is being collected to assure compliance with 40 CFR Part 60, Subpart QQQQ.
