NESHAP for Flexible Polyurethane Foam Fabrication (40 CFR part 63, subpart MMMMM) (Final Rule)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities (40 CFR Part 63, Subpart FFFFF) apply to new and existing sinter plants, blast furnaces, and basic oxygen process furnace shops at integrated iron and steel manufacturing facilities that are major sources of hazardous air pollutants (HAPs) or are co-located at major sources. New facilities include those that commenced either construction or reconstruction after the date of proposal. In general, all NESHAP 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 NESHAP. This information is being collected to assure compliance with 40 CFR Part 63, Subpart FFFFF.
