National Emission Standards for Hazardous Air Pollutants: Leather Finishing Operations Residual Risk and Technology Review

On March 14, 2018, the Environmental Protection Agency (EPA) proposed a rule titled, ``National Emission Standards for Hazardous Air Pollutants: Leather Finishing Operations Residual Risk and Technology Review.'' The EPA is reopening the comment period on the proposed rule that closed on April 30, 2018. The EPA is taking this action because the supporting document--Analysis of Demographic Factors for Populations Living Near Leather Finishing Operations--was inadvertently not included in the docket for this proposed rule. As this analysis is now available to the public, the EPA has reopened the comment period for an additional 30 days.
