Current through Register Vol. 47, No. 24, December 25, 2024
Section 5 CCR 1001-30-B-V - Control of Emissions from Foam Manufacturing in the 8-hour Ozone Control AreaV.A. Requirements for Foam Product Manufacturing V.A.1. Applicability V.A.1.a. Except as provided in Section V.A.2., the requirements of Section V. apply to owners or operators of foam manufacturing operations that existed at a major source of VOC (greater than or equal to 50 tpy VOC) as of January 27, 2020, located in the 8-hour Ozone Control Area.V.A.1.b. Except as provided in Section V.A.2., the requirements of Section V. apply to owners or operators of foam manufacturing operations that existed at a major source of VOC (greater than or equal to 25 tpy VOC) as of November 7, 2022, located in the 8-hour Ozone Control Area.V.A.2. Exemptions Any foam manufacturing operation that uses only non-VOC blowing agents is exempt from this Section V.A.
V.A.3. Definitions V.A.3.a. "Blowing agent" means any liquid, gaseous or solid substance that alone or in conjunction with other substances is capable of producing a cellular (foam) structure in a polymeric material.V.A.3.b. "Expandable polystyrene (EPS) beads" means polystyrene beads, particles, or granules, usually less than one-twelfth inch in diameter, that are formulated with a blowing agent (typically 3.5% to 7% of bead weight). When subjected to prescribed heating in an expansion system, the beads puff up, expanding many times their original volume into low density foam globules (called "prepuff" or "puff") from which a variety of EPS foam products are molded.V.A.3.c. "Expanded polystyrene (EPS) foam" means a lightweight, foam material, made of polystyrene, from which a variety of common items are made, such as ice-chests, insulation board, protective packaging, and single-use cups.V.A.3.d. "Foam" means a solid material in a lightweight cellular form (having internal voids or cavities called cells that contain air or a gas) resulting from the introduction or generation of gas bubbles throughout its mass during processing.V.A.3.e. "Foam manufacturing operation" means any EPS production line, or portion of a production line, which processes raw EPS bead into final molded EPS product. Production line processes include, but are not limited to: pre-expansion, aging (pre-puff), and molding. The manufacturing process ends after the product exits the EPS mold. "Foam manufacturing operation" also means any production line processing methylene diphenyl diisocyanate (MDI), resins, and various hardeners and thickeners into foam products and which results in VOC emissions into the atmosphere. The manufacturing process ends after the product exits the drying tunnel.V.A.3.f. "Non-VOC blowing agent" means a blowing agent which does not contain VOCs.V.A.3.g. "Polystyrene" means any grade, class, or type of thermoplastic polymer, alloy, or blend that is composed of at least 80% polymerized styrene by weight.V.A.3.h. "Raw material" means all polystyrene, polyethylene and polypropylene, and blowing agent used in the manufacture of foam products.V.A.4. Emission Limitations V.A.4.a. By May 1, 2022, for sources subject pursuant to Section V.A.1.a. and by May 1, 2024, for sources subject pursuant to Section V.A.1.b., owners and operators of foam manufacturing operations must eitherV.A.4.a.(i) Limit VOC emissions from foam manufacturing to 3.0 lbs. per 100 lbs. of total material process, averaged monthly, orV.A.4.a.(ii) Control VOC emissions from foam manufacturing by 90%. The control device must have a control efficiency of at least 95%.V.A.5. Work Practices The owner or operator of any foam manufacturing operation must implement the following work practice requirements at all times to reduce VOC emissions from fugitive sources.
V.A.5.a. Store raw materials in closed, leak-free, labeled containers when not in use.V.A.5.b. Cover open containers in a manner that minimizes evaporation into the atmosphere.V.A.6. Monitoring V.A.6.a. The owner or operator of foam manufacturing operations must operate and maintain the control device consistent with the manufacturer's specifications.V.A.6.b. By November 1, 2022, and every three (3) years afterward, owners or operator of foam manufacturing operations must conduct a performance test during representative operations using EPA Method 24 (October 7, 2020) to determine VOC content and EPA Method 18, 25, or 25A (November 14, 2018) to determine control efficiency of the emission control equipment.V.A.7. Recordkeeping The following records must be kept for a period of five (5) years and made available to the Division upon request
V.A.7.a. Any records necessary to demonstrate that an exemption in Section V.A.2. applies.V.A.7.b. The amount of raw material processed on a daily basis.V.A.7.c. The type of blowing agent used.V.A.7.d. The amount of blowing agent used on a monthly basis.V.A.7.e. The total monthly VOC emissions.V.A.7.f. For operators complying with the emission limitation in Section V.A.4.a.(i), the total monthly VOC emissions calculated on a pounds per 100 lbs. of material processed basis.V.A.7.g. For operators that use a control device to comply with the emission limitations in Section V.A.4.a.V.A.7.g.(i) A manufacturer guarantee of the control equipment's emission control efficiency to demonstrate compliance with Section V.A.4.V.A.7.g.(ii) The amount of supplementary natural gas combusted in the control device on a monthly basis.V.A.7.g.(iii) Records of performance tests conducted pursuant to Section V.A.6.V.A.7.h. Records of calendar year VOC emission estimates demonstrating whether the foam manufacturing operation meets or exceeds the applicability threshold in Section V.A.1.V.A.8. Reporting V.A.8.a. Performance test protocols required for performance tests under Section V.A.6.b. must be submitted to the Division for review at least thirty (30) days prior to testing and in accordance with AQCC Common Provisions Regulation Section II.C.46 CR 10, May 25, 2023, effective 6/14/202347 CR 02, January 25, 2024, effective 2/14/2024
