NESHAP for Off-Site Waste and Recovery Operations (40 CFR part 63, subpart DD) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Off-Site Waste and Recovery Operations (OSWRO) apply to existing facilities and new facilities with organic hazardous air pollutant (HAP) emissions that are involved in waste management and recovery operations, and that are not subject to Federal air standards under other subparts in Part 63. In addition, Subpart DD cross-references control requirements to be applied to specific types of affected sources: tanks level-1; containers; surface impoundments; individual drain systems; oil-water separators; organic water separators; and loading, transfer, and storage systems. New facilities include those that commenced either construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart DD. In general, all NESHAP standards require initial notification reports, 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.
