85. AQ-2023-003-RULE 331 (SOLVENT CLEANING) Set a public hearing, as required by Arizona Revised Statutes (A.R.S.) § 49-479(b), for September 25, 2024, at 9:30 a.m. to solicit comments on the proposed revision of Maricopa County Air Pollution Control Regulations, Rule 331 (Solvent Cleaning) and the associated proposed revision to the Arizona State Implementation Plan (SIP). Following the public hearing, the Board is requested to adopt the proposed amendments to the rule and to approve submission of the amended rule as a revision to the Arizona SIP. Rule 331 establishes limits for emissions of volatile organic compounds (VOCs) from solvent cleaning operations. Rule 331 applies to operations using VOC-containing solvents to remove impurities from exterior or interior surfaces. The Maricopa County Air Quality Department (MCAQD) is proposing to revise Rule 331 to remove a reasonably available control technology (RACT) deficiency identified by the U.S. Environmental Protection Agency so Rule 331 can be approved into the Arizona SIP as meeting RACT. In addition, MCAQD is proposing other revisions to the rule including lowering the VOC content limit in the definition of Low-VOC Cleaner from 50 grams of VOC per liter to 25 grams of VOC per liter as well as restructuring the rule for clarity purposes. MCAQD plans to replace SIP Rule 34, Sections F-K (Organic Solvents – Volatile Organic Compounds (VOC)) and current SIP Rule 331 with the revised rule to update the SIP and clarify regulatory requirements.
