National Emission Standards for Hazardous Air Pollutants for Chemical Manufacturing Area Sources

Riepilogo

EPA is issuing national emission standards for the control of hazardous air pollutants for nine area source categories in the chemical manufacturing sector: Agricultural Chemicals and Pesticides Manufacturing, Cyclic Crude and Intermediate Production, Industrial Inorganic Chemical Manufacturing, Industrial Organic Chemical Manufacturing, Inorganic Pigments Manufacturing, Miscellaneous Organic Chemical Manufacturing, Plastic Materials and Resins Manufacturing, Pharmaceutical Production, and Synthetic Rubber Manufacturing. The standards and associated requirements for the nine area source categories are combined in one subpart. This final rule establishes emission standards in the form of management practices for each chemical manufacturing process unit as well as emission limits for certain subcategories of process vents and storage tanks. The rule also establishes management practices and other emission reduction requirements for subcategories of wastewater systems and heat exchange systems.
