Municipal Solid Waste Landfills: National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
Rule Summary
The final rule is applicable to both major and area sources and contains the same requirements as the Emission Guidelines and New Source Performance Standards (EG/NSPS), promulgated in 1996. The final rule adds startup, shutdown, and malfunction (SSM) requirements, adds operating condition deviations for out-of-bounds monitoring parameters, requires timely control of bioreactor landfills, and changes the reporting frequency for one type of report.
The hazardous air pollutants (HAP) emitted by municipal solid waste (MSW) landfills include, but are not limited to, vinyl chloride, ethyl benzene, toluene, and benzene. Each of the HAP emitted from MSW landfills can cause adverse health effects provided sufficient exposure.
