RULE 1175 - CONTROL OF EMISSIONS FROM THE MANUFACTURE OF POLYMERIC CELLULAR (FOAM) PRODUCTS
(Adopted November 3, 1989)(Amended January 5, 1990)(Amended May 13, 1994)
This rule shall apply to polymeric cellular products manufacturing operations including but not limited to expandable polystyrene, polystyrene foam extrusion, polyurethane, isocyanurate and phenolic foam operations. All steps of the manufacturing operation and the storage of the final product for a maximum of 48 hours are subject to the requirements of this rule.
For the purpose of this rule, the following definitions shall apply:
(A) The emission collection system shall collect at least a 90 percent by weight of the manufacturing emissions; and
(B) The control device shall reduce emissions from the emission collection system by at least 95 percent, by weight.
(A) Group I (General)
cyclic, branched, or linear, completely fluorinated alkanes
cyclic, branched, or linear, completely fluorinated ethers with no unsaturations
cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations
sulfur-containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine
(B) Group II
1,1,1-trichloroethane (methyl chloroform)
The use of Group II compounds and/or carbon tetrachloride may be restricted in the future because they are toxic, potentially toxic, upper-atmosphere ozone depleters, or cause other environmental impacts. By January 1, 1996, chlorofluorocarbons (CFC), 1,1,1,-trichloroethane (methyl chloroform), and carbon tetrachloride will be phased out in accordance with the Code of Federal Regulations Title 40, Part 82 (December 10, 1993).
(c) Emission Control Requirements
(A) By January 1, 1994, each polyurethane operation subject to the rule shall discontinue its use of CFCs, VOCs, or methylene chloride.
(B) Each manufacturing operation, excluding rigid polyurethane operations shall reduce yearly emissions from its 1988 emissions baseline, based on Rule 301 emission fees filing, by 100 percent, beginning calendar year 1994.
The owner or operator of an expandable polystyrene (EPS) molding operation shall demonstrate, to the satisfaction of the Executive Officer, that manufacturing emissions and post-manufacturing emissions, assuming all the blowing agent is released from the product, are less than 2.4 lbs per 100 lbs of raw material processed.
(A) Submit permit applications for the installation of an emission control system within four months of the date that compliance with such requirement was not achieved; and
(B) Within 12 months of failing to meet the requirements of subparagraph (c)(1), (c)(2), or (c)(3), the following provisions must be satisfied:
(i) An approved emission control system is installed and operating with all sources of manufacturing emissions vented only to the approved emission control system; and
(ii) Emissions from the final manufactured product are vented only to the approved emission control system for at least:
(I) 48 hours, in the case of expandable polystyrene molding operations that process more than 800,000 pounds per calendar year of raw material; or
(II) 24 hours, in the case of all other manufacturing operations.
(A) Expandable polystyrene operation that processes less than 200 pounds per day of raw material.
(B) Rigid polyurethane operation that processes less than 1,000 pounds per day of raw material.
(A) rigid polyurethane foam; or
(B) EPS foam and the highest concentration of the blowing agent in the cellular product is 1.8 percent or less by weight within 15 minutes of completion of the manufacturing operation. Verification of the concentration shall be demonstrated annually, pursuant to a protocol submitted to the District and subject to approval by the Executive Officer.
(f) Test Methods
The VOC content of materials subject to the provisions of this rule shall be determined by the following methods:
(A) United States Environmental Protection Agency (USEPA) Reference Method 24 (Code of Federal Regulations Title 40 Part 60, Appendix A,). The exempt solvent content shall be determined by SCAQMD Method 303 (Determination of Exempt Compounds) contained in the SCAQMD "Laboratory Methods of Analysis for Enforcement Samples" manual; or,
(B) SCAQMD Method 304 [Determination of Volatile Organic Compounds (VOCs) in Various Materials] contained in the SCAQMD "Laboratory Methods of Analysis for Enforcement Samples" manual.
(C) Exempt Perfluorocarbon Compounds
The following classes of compounds will be analyzed as exempt compounds for compliance with paragraph (c), only when manufacturers specify which individual compounds are used in the coating formulation:
cyclic, branched, or linear, completely fluorinated alkanes;
cyclic, branched, or linear, completely fluorinated ethers with no unsaturations;
cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations; and
sulfur-containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine.
In addition, the manufacturers must identify the test methods approved and used by the United States Environmental Protection Agency, California Air Resources Board, and the District to quantify the amount of each exempt compound.
The weight percent pentane in expandable polystyrene polymer shall be determined by SCAQMD Method 306 (Analysis of Pentanes in Expandable Styrene Polymers) contained in the SCAQMD "Laboratory Methods of Analysis for Enforcement Samples" manual.
(A) The efficiency of the collection device of the emission control system required in paragraph (c)(4) shall be determined by the USEPA method cited in 55 Federal Register 26865 (June 29, 1990), or any other method approved by the United States Environmental Protection Agency, the California Air Resources Board, and the District.
(B) The efficiency of the control device of the emission control system required in paragraph (c)(4) and the VOC content in the control device exhaust gases, measured and calculated as carbon, shall be determined by USEPA Test Methods 25, 25A, or SCAQMD Method 25.1 (Determination of Total Gaseous Non-Methane Organic Emissions as Carbon) as applicable. USEPA Test Method 18, or ARB Method 422 shall be used to determine emissions of exempt compounds.
When more than one test method or set of test methods are specified for any testing, a violation of any requirement of this rule established by any one of the specified test methods or set of test methods shall constitute a violation of the rule.
