The Environmental Quality Board amended 25 Pa. Code Chs. 121 and 129, Adhesives, Sealants, Primers and Solvents. The change adds definitions to §121.1 (relating to definitions) for 57 new terms, including those that relate to the adhesive, sealant, primer, and solvent product categories that will be regulated under §129.77 (relating to control of emissions from the use or application of adhesives, sealants, primers and solvents). The rule will now regulate the owner or operator of a facility or stationary source that uses or applies, on or after January 1, 2012, a regulated adhesive, sealant, adhesive primer, or sealant primer product. The rule now includes emission standards and volatile organic compound content limits for the industrial or commercial use or application of 37 categories of adhesive, sealant, adhesive primer, or sealant primer products, and adhesive or sealant products applied to particular substrates. The final-form rulemaking also includes requirements for the use of surface preparation solvents and cleanup solvents. http://www.pabulletin.com/secure/data/vol40/40-52/2456.html.
