Public comment is currently being accepted on a draft Air Operating Permit (AOP) renewal and Notice of Construction (NOC) modification for for Rohm and Haas Chemicals LLC, located in Elma, Washington, pursuant to Title V of the federal Clean Air Act and Chapter 173-401 of the Washington Administrative Code.
Rohm and Haas Chemicals LLC (Rohm and Haas) has requested a voluntary limit on emissions of hazardous air pollutants (HAPs) at their specialty chemical production plant in Elma, Washington. Rohm and Haas has proposed to limit emissions of all HAPs to less than 10 tons per year of any single HAP and less than 25 tons per year of all combined HAPs. The limit would replace their current facility-wide methanol limit of 60 tons per year established in Notice of Construction# 01MOD189. The purpose of this request is to establish enforceable emission limits thereby allowing classification of the facility as a minor source with respect to any National Emission Standards for Hazardous Air Pollutants with a future compliance date.
Simultaneous with their application requesting voluntary limits on HAP emissions, a draft Air Operating Permit (AOP) renewal for Rohm and Haas is available for review. AOPs are required pursuant to Title V of the federal Clean Air Act and are designed to help ensure compliance with applicable air quality regulations and standards. AOPs are required to be renewed every five years. Rohm and Haas’s plant in Elma requires an AOP because it is a major source with respect to the National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical Manufacturing. This will be the 2nd renewal of the AOP for Rohm and Haas.
ORCAA has reviewed Rohm and Haas’ request and concluded that the proposed emissions limits will likely comply with all applicable air regulations and standards. On this basis, ORCAA’s Preliminary Recommendation is to approve Rohm and Haas’ application.
Copies of the Preliminary Recommendation, draft AOP renewal and the associated Technical Support Document (TSD) for Rohm and Haas Chemicals LLC are on file and available for review at the Elma Library at 118 N. First Street in Elma, and at ORCAA’s office in Olympia. The Preliminary Recommendation, draft AOP and TSD are also accessible here.
