The BWON Rule Explained
The Benzene Waste Operations NESHAP (BWON) regulation (40 CFR 61 Subpart FF) has governed wastewater benzene emissions since 1993, with significantly strengthened enforcement campaigns in 2023-2025. This EPA regulation specifically targets waste streams from petroleum refineries and chemical manufacturing facilities.
No Detectable Emissions (NDE) Requirements
Regulated controlled benzene waste streams must use equipment designed for no detectable emissions, verified through Method 21 readings of ≤500 ppm and tested annually.
Enhanced Enforcement
Recent enforcement includes optical gas imaging (OGI) for leak detection, resulting in high-profile fines and consent decrees with penalties up to $40M and required capital projects reaching $250M.
Waste Management Units
Regulated equipment includes oily water separators, tanks, individual drain systems, containers, control devices, and vent systems – all requiring rigorous documentation and testing.
