National Emission Standards for Hazardous Air Pollutants for Chemical Recovery Combustion Sources at Kraft, Soda, Sulfite, and Stand-Alone Semichemical Pulp Mills

Краткое содержание

The Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Chemical Recovery Combustion Sources at Kraft, Soda, Sulfite, and Stand-Alone Semichemical Pulp Mills to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct under the Clean Air Act (CAA). These proposed amendments include revisions to the opacity monitoring provisions; addition of electrostatic precipitator (ESP) parameter monitoring provisions; a requirement for 5-year periodic emissions testing; revisions to provisions addressing periods of startup, shutdown, and malfunction (SSM); and technical and editorial changes. The EPA is proposing these amendments to improve the effectiveness of the rule.
