IMA-NA Files Ozone Comments on Behalf of Western Operations

Posted By Darrell Smith, Wednesday, March 18, 2015
The Industrial Minerals Association – North America, on behalf of Wyoming soda ash producers Solvay Chemicals, Inc. and TATA Chemicals North America, as well as other mineral operations in the western United States, appreciates the opportunity to comment on the Environmental Protection Agency’s (EPA) proposed ozone NAAQS, 79 Fed. Reg. 75234 (Dec. 17, 2014) (Proposed Rule). EPA’s proposal to lower the ozone NAAQS from 75 parts per billion (ppb) to a range of between 65 ppb and 70 ppb will substantially affect IMA-NA member operations across the country, including those located in western States where existing background ozone levels are likely to preclude attainment with the standard. Until such time as EPA addresses the concerns outlined in these comments, EPA should not finalize an ozone standard lower than the current NAAQS of 75 ppb and should commit instead to working cooperatively with states and industry to effectively implement that standard.
