The U.S. Chamber of Commerce sent the following letter to The White House underscoring the Chamber's support for maintaining the existing standards for fine particulate matter under the National Ambient Air Quality Standards (NAAQS).
EPA is considering discretionary action to lower standards which would lead to permitting gridlock that will hinder our ability to build new infrastructure, expand manufacturing, and grow our economy. In addition, EPA’s proposal lacks transparency and lacks adequate factual analysis, as it has dramatically underestimated the impact of tighter standards by only partially estimating the geographic extent and costs of tightening the standards.
