The U.S. Environmental Protection Agency (EPA) is proposing amendments to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct in accordance with the Clean Air Act (CAA) with regard to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Refractory Products Manufacturing. The EPA is proposing to find the risks due to emissions of air toxics from this source category under the current standards to be acceptable and that the standards provide an ample margin of safety to protect public health.

The U.S. Environmental Protection Agency (EPA) is proposing the results of the residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for mercury emissions from Mercury Cell Chlor-Alkali Plants, as required by the Clean Air Act (CAA).

Reducing childhood lead exposure is a priority for the Environmental Protection Agency (EPA). As part of EPA's efforts to reduce childhood lead exposure, and in coordination with the President's Task Force on Environmental Health Risks and Safety Risks to Children, EPA reevaluated the 2001 dust-lead clearance levels (DLCL). Clearance levels indicate the amount of lead in dust on a surface following the completion of an abatement activity. Surface dust is collected via dust wipe samples that are sent to a laboratory for analysis to determine whether clearance has been achieved.

The U.S. Environmental Protection Agency (EPA) is finalizing 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, and the New Source Performance Standards (NSPS) for Kraft Pulp Mills constructed, reconstructed, or modified after May 23, 2013. The final rule clarifies how to set operating limits for smelt dissolving tank (SDT) scrubbers used at these mills and corrects cross-reference errors in both rules.
