The National Stone, Sand & Gravel Association reports that the U.S. Environmental Protection Agency is under court order to issue a revised opacity rule by April 16.

The rule limits how much visible dust is allowed to be emitted to the air from crushers, screens and conveyor transfer points. In response to a lawsuit filed last year by the Sierra Club against EPA, NSSGA has negotiated a final rule that would lessen the administrative burden on the aggregates industry, NSSGA says.

The Sierra Club claimed in its lawsuit that the existing opacity standards are too easily achievable by industry. NSSGA says it used data from 23 states and more than 600 individual source tests to discounted the Sierra Club claim and proved to EPA that the federal standards do more than an adequate job of protecting public health and welfare from fugitive dust emissions from aggregate processing plants.

NSSGA says it will issue a summary of the final rule and host several webinars demonstrating the changes to the rule and how it affects their individual operations.
