SCAQMD is accepting comments on the AQMP through Aug. 19. ACA's Architectural and Industrial Maintenance (AIM) volatile organic compound (VOC) and Industrial Air Regulatory Committees will be submitting comments by that deadline.
The district's AQMP seeks volatile organic compound (VOC) emission reductions by focusing on select coating, adhesive, solvent, and sealant categories by further limiting the allowable VOC content in formulations or incentivizing the use of super-compliant technologies. Examples of the categories to be considered include, but are not limited to: coatings used in aerospace applications; adhesives used in a variety of sealing applications; and solvents for graffiti abatement activities. Reductions could be achieved by lowering the VOC content of the coatings, solvents, adhesives, and sealants where possible, but reductions could also be achieved by promoting the use of alternative low-VOC products or non-VOC product/equipment at industrial facilities.
The following provides an overview of the district's proposed future regulatory actions:
- Rule 1107 – Coating of Metal Parts, and Rule 1168 – Adhesive and Sealant Applications Amendments
In general, SCAQMD is looking for 1 ton per day of VOC reductions, likely from both categories. Both rules were suspended until the Heath Risk Assessment (HRA) on tertiary-Butyl Acetate (tBAc) is finalized. Once the HRA is finalized, the amendments will resume.
- Rule 1106 – Marine Coating Operations, and Rule 1106.1 – Pleasure Craft Coating Operations
SCAQMD's Governing Board did not adopt proposed amendments to these rules in 2015 due to proposed recordkeeping requirements, but staff still intends to combine the rules to promote clarity and evaluate whether the rules satisfy Reasonably Available Control Technology (RACT) requirements.
- Rule 1124 – Aerospace Assembly and Component Manufacturing Operations
The district is evaluating whether the rule satisfies RACT requirements.
- Rule 1128 – Paper, Fabric, and Film Coating Operations
The district is evaluating the applicability of spray booths or non-coating line processes used in paper, fabric, and film coating operations.
- Rule 1136 – Wood Product Coatings
The district is considering restriction or elimination of potential loopholes and evaluate toxic emissions resulting from furniture stripping.
- Rules 314 – Fees for Architectural Coatings, Rule 1113 – Architectural Coatings, Rule 1143 – Consumer Paint Thinners and Multi-Purpose Solvents, and 1171 – Solvent Cleaning Operations
The district is assessing the potential to achieve State Implementation Plan (SIP) reductions through certification programs (e.g., Clean Air Solvent, Clean Air Choices Cleaner Product Certification, or a coatings certification program) or reporting programs.
