NEP (National Emission Standards for Hazardous Air Pollutants)
NEP (National Emission Standards for Hazardous Air Pollutants) are regulations set by the U.S. Environmental Protection Agency to limit emissions of harmful substances from industrial sources. They aim to protect public health and the environment by establishing specific limits and requirements for facilities that produce or release hazardous air pollutants, such as chemicals or toxins. Facilities must follow these standards to reduce pollution, often implementing control technologies or practices. In essence, NEP ensures industries operate in ways that minimize dangerous emissions, balancing economic activity with environmental and health safety.
