This is the third Title V Renewal permit for this facility. With the renewal, the facility requested to delete four discontinued production operations from the air permit coverage. The facility is removing sources SN-27, SN-30, SN-36 and SN-37. The total permitted emission rate limit changes associated with this activity includes -0.10 tpy PM, -0.10 tpy PM10, -4.40 tpy VOCs, - 0.44 tpy Acetone and -3.80 tpy Ammonia. Process Description Blue Cube Operations LLC (Blue Cube) operates an industrial facility located in Russellville, Arkansas. The physical address of the site is 3230 Dow Drive. Cathode and anode electrodes for chlorine (“chlor-alkali”) production cells are made and refurbished at the plant. The polymer concrete components for these units are also fabricated onsite. The manufacturing operations at the Russellville facility are properly categorized using Standard Industrial Classification (SIC) Code #3559 (special industrial machinery, not elsewhere classified). The corresponding North American Industry Classification System (NAICS) Code is #333298 (all other industrial machinery manufacturing). Blue Cube is a wholly owned subsidiary of Olin Corporation (Olin). Blue Cube Operations LLC merged with Olin on October 5, 2015. The production activities at the Blue Cube facility include the following: the casting of polymer concrete frames, covers and other parts for chlorine cells; the fabrication of cathode and anode electrodes; the refurbishing of certain anode units; several electrode-coating processes; numerous grit blasting and grinding operations; and, a variety of miscellaneous industrial activities. CASTING OF REINFORCED POLYMER CONCRETE COMPONENTS FOR DIAPHRAGM CELLS (PRODUCTION UNIT #5) Blue Cube makes frames, covers and other components for chlorine production cells (“diaphragm” -type units). These reinforced “polymer concrete” parts are made in Production Unit #5. The manufacturing operations are described below: The raw materials for the batch casting operations include several styrene-based “epoxy vinyl ester resins”, sand, chopped fiberglass, and miscellaneous ingredients. The primary casting material is a styrene-based resin. This product is delivered in bulk by truck. The material is stored in the casting resin tank (SN-08R). This aboveground, vertical vessel has a storage capacity of 14,300 gallons. The insulated tank is chilled to maintain the stability of the styrene-based resin and pumped into a 500-gallon “day tank” (SN-08A) that supplies the casting operations. 5 Blue Cube Operations LLC Permit #: 0801-AOP-R10 AFIN: 58-00011 Four additional casting compounds are received in 350-gallon tote bins and/or 55-gallon drums (SN-09A). Sand for the casting operations is delivered in bulk by truck. The material is pneumatically unloaded into a large storage silo (SN-02A). The silo is equipped with a baghouse. It is used to control the dust emissions generated during the unloading operations. The material is subsequently transferred to a bulk resin mixer located inside Production Unit #5. The sand transfer system (SN-03A) encompasses all of the conveying and handling equipment from the storage silo to the mixer. These units include a bucket elevator, two belt conveyors, a screener, a weigh
