NESHAP for Cellulose Products Manufacturing (40 CFR part 63, subpart UUUU) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Cellulose Products Manufacturing (hereafter referred to as the NESHAP) was proposed on August 28, 2000, promulgated on June 11, 2002, and most recently amended on February 27, 2014. This supporting statement addresses information collection activities imposed by the Cellulose Products Manufacturing NESHAP, including both activities for which the burden has previously been approved and activities added based on the residual risk and technology review (RTR) required under the Clean Air Act (CAA). These information collection activities are required to assure compliance with 40 CFR Part 63, Subpart UUUU, as amended. The NESHAP applies to each existing, reconstructed, and new Cellulose Products Manufacturing operation that is a major source of hazardous air pollutant (HAP) emissions or is collocated with other sources that are individually or collectively a major source of HAP emissions. A major source emits or has the potential to emit any single HAP at the rate of 10 tons (9.07 megagrams) or more per year, or any combination of HAP at a rate of 25 tons (22.68 megagrams) or more per year. The Cellulose Products Manufacturing source category comprises the miscellaneous viscose production source category and cellulose ether production source category. The miscellaneous viscose processes source category currently includes the cellulose food casing, cellophane, and cellulosic sponge industry sectors. (All facilities in the rayon industry sector, which had been part of the category, have shut down.) The cellulose ethers production source category includes the carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, and methyl cellulose industry sectors. New facilities include those that commenced construction, or reconstruction after the date of the original proposal (August 28, 2000). As part of the RTR amendments to the Cellulose Products Manufacturing NESHAP, the EPA eliminated the startup, shutdown, and malfunction (SSM) exemption; removed the SSM plan requirement; added periodic performance testing; provided biofilter effluent conductivity as an alternative to monitoring pH; added electronic submittal of notifications, semiannual reports and performance test reports; and made other technical and editorial changes. The remaining portions of the NESHAP remain unchanged. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. Owners/operators are also required to maintain records of the occurrence and duration of any failures to meet applicable standards; startup, shutdown, or malfunction in the operation of an affected facility; and any period during which a monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance and are required of all affected facilities subject to NESHAP.
