Standards of Performance for Equipment Leaks of VOC in the Synthetic Organic Chemicals Manufacturing Industry; Standards of Performance for Equipment Leaks of VOC in Petroleum Refineries

Riepilogo

Pursuant to section 111(b)(1)(B) of the Clean Air Act, the EPA has reviewed the emission standards for volatile organic compounds contained in the standards of performance for equipment leaks of volatile organic compounds in the synthetic organic chemicals manufacturing industry and equipment leaks of volatile organic compounds in petroleum refineries. This action proposes amendments to these standards based on this review. Specifically, we are proposing amendments to increase the stringency of the leak definitions for pumps and valves. We are also proposing several technical clarifications and corrections to existing provisions. The clarifications and corrections in the regulations would apply to all sources that are subject to rules that reference these regulations.
