Both EPA and OSHA continue to be very active with regulations and guidance. Some of the more significant EPA and OSHA regulations that could impact cotton gins are discussed. For EPA these include air quality activities (the new NAAQS for PM and ozone, proposals for regional haze and non-road diesel engines, MACT standard for process heaters, and accidental release prevention for propane) and TSCA activities (review of respirable cotton fibers). For OSHA these include the Cooperative Compliance Program (CCP), the safety and health program standard, ergonomics, crystalline silica and others.
