Ado pte d S ept emb er 10, 20 08 Reg . I I, Rul e 2 .41 , P age2 100 GENERAL 101 PURPOSE: The purpose of this rule is to limit the emissions of volatile organic compounds (VOCs) from the manufacturing of expanded polystyrene (EPS) products. 102 APPLICABILITY: The provisions of this rule are applicable to any facility which manufactures EPS products. 110 EXEMPTION - Non-VOC Blowing Agent: The provisions of this rule shall not apply to any EPS manufacturing operation which uses only non-VOC blowing agents. 200 DEFINITIONS 201 BLOWING AGENT: Any liquid, gaseous, or solid material that facilitates the formation of a cellular product from raw polymeric material. 202 CERTIFICATE OF ANALYSIS (COA): A written document, originated by the EPS bead manufacturer, which cites the blowing agent content (expressed as percentage by weight) of the EPS bead in a specific manufactured bead lot prior to shipment from the manufacturer. 203 EMISSION CONTROL SYSTEM: A system for reducing manufacturing emissions, which consists of a capture system and a control device. 204 EXPANDABLE POLYSTYRENE (EPS): A lightweight closed-cell foam which is manufactured in a range of densities. 205 EPS PRODUCTS: Foam products which are manufactured from a series of processes where ra wpolymeric materials containing a blowing agent, such as beads, are expanded by exposure to steam or other expansion agent and subsequently molded into final product, such as blocks. 206 EPS MANUFACTURING EMISSIONS : Any VOC emissions which occur during an EPS manufacturing ope ration, prior to capture and control. 207 EPS MANUFACTURING OPERATION : Any EPS production line, or portion of a production line, which processes raw EPS bead into final EPS product and which results in VOC emissions into the atmosphere. Production line processesYol o-S ola no AQMD

include, but are not limit ed to: pre-expansion, aging (pre-puff), and molding. The manufacturing process ends after the EPS product exits the mold. 208 LOW PENTANE BEAD: An expandable polystyrene bead containing pentane as a blowing agent with an upper limit less than 4.0 percent by weight, prior to shipm e n t , as certified upon delivery by an accompanying bead manufacturer’s COA. 209 MID PENTANE BEAD : An expandable polystyrene bead containing pentane as a blowing agent within the range of 4.0 to 5.2 percen t b y weight, prior to shipment, as certified upon delivery with an accompanying bead manufacturer’s COA. 210 NON-VOC BLOWING AGENT: A blowing agent which does not contain VOCs. 211 POLYMERIC MATERIAL : A multi-molecular compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units. 212 VOLATILE ORGANIC COMPOUND (VOC) : As defined in Rule 1.1, General Provisions and Definitions. 300 STANDARDS 301 EMISSION CONTROLS: All EPS manufacturing emissions shall be controlled by an emission control system which has a capture efficiency of at least 90% and a des t r u ction efficiency of at least 95%. 302 RAW M

ATERIAL USAGE: All EPS products shall be manufactured with either low or mid pentane bead. 303 SOURCE TESTING: Each EPS manufacturing operation shall perform a source test to verify compliance with section 301 at least once every 12 calendar months, in accordance with a District

- a p proved protocol and the test methods listed in section 600. 304 VIOLATIONS: Failure to comply with any provision of this rule shall constitute a violation of this rule. The owner or operator shall be liable for any penalties assessed in accordance with the Cal ifornia Health and Safety Code 42400.Yol o-S ola no AQMD

I I, Rul e 2 .41 , P age4 400 ADMINISTRATIVE REQUIREMENTS 401 COMPLIANCE SCHEDULE: Facilities subject to the requirements of this rule shall demonstrate full compliance with all provisions by January 1, 2009. 402 EMISSION CONTROL SYSTEM OPERATION AND MAINTENANCE (O&M) PLANS: T h e owner/operator shall submit an O&M plan for the emission control system to the APCO for approval. The plan shall i n c l ude procedures for collecting and recording required data and other information in a form approved by the APCO. The plan shall also i n clude procedures and schedules for preventive and corrective maintenance performed for the purpose of maintaining the emission control system in proper operating condition. 500 REPORTING AND RECORD KEEPING 501 REPORTING: All records required by this Rule shall be maintained on site for a period of five years and made available to the APCO upon request. 502 RECORD KEEPING: Owners and/or operators shall maintain the following records: 502.1 EMISSION CONTROL SYSTEM: Daily records of the

operation and maintenance of the emission control system. These records shall include key system operating parameters such as temperatures, pressures, flow rates, and other measurements to demonstrate ongoing compliance with section 300. 5 0 2

bead processed and the associated blowing agent content, as specified on the applicable COA. A copy of each a p p l i cable COA shall be retained. 502.3 FINISHED PRODUCT: Daily records of the amount

of EPS product made, including the approximate weight and density of each product. 600 TEST METHODS AND CALCULATIONS 601 GENERAL: For the purposes of this Rule, the followingYol o-S ola no AQMD

test methods (or their most recent approved versions) or calculation methods shall be used, upo n r e v iew and approval by the D i strict and EPA. Other test methods determined to be equivalent and approved i n w riting by the District and the EPA may also be used. 602 FLOW: Measurement of air flow and gas fl o w s h all be conducted and reported in accordance with EPA Reference Methods 1 and 2, and their subparts. 603 VOC LEAKS: Measurement of VOC leaks shal l b e conducted and reported in accordance with EPA Reference Method 21. 604 CONTROL EFFICIENCY: Measurement of VOC concentration for determining control efficiency shall be conducted and reported in accordance with EPA Reference Method 25, and its subparts. 605 PENTANE CONTENT: Measurement of pentane content of materials shall be conducted and reported in accordance with SCAQMD Method 306-91. 606 MOISTURE CONTENT: Measurement of moisture content of gas sha l l be conducted and reported in accordance with EPA Reference Method 4. 607 CAPTURE EFFICIENCY: Measurement of capture efficiency shall b e determined by the procedures contained in the EPA technical guidance document “Guidelines for Determining Capture Efficiency, January 9, 1995", and EPA Reference Methods 204 A-F.
