Dow Silicones Corporation Greensboro, North Carolina Stormwater Permit NCS000077 Best Management Practices January 2019 Best Management Practices (BMPs) Best management (BMPs) includes proper equipment design and operation, manufacturing and material handling procedures, structural controls and landscaping practices. • Spill Containment Structures: Containment structures are constructed of concrete and concrete block. All containment structures are sized to hold the contents of the largest tank in addition to accumulated rainwater. Each containment structure has the maximum level for rainwater clearly marked such that the structure will still hold the contents of the largest storage tank. • Drainage from Containment Areas: All containment areas have manually operated valves or pumps, which remain closed and locked when not in operation. Drain valves are on/off type — no flapper type valves are used. Accumulated stormwater is inspected and inspection results are documented before stormwater is released. Only trained personnel may inspect and release stormwater. • Storage Tank Design and Installation: All storage tanks are constructed of materials compatible with material stored and operating pressure and temperature. All storage tanks have concrete secondary containment structures. All bulk storage tanks have high level interlocks that will stop material transfer when tripped. • Material Loading/Unloading: All bulk material handling is performed in spill - contained areas. Standard Operating Procedures are required for all bulk material handling operations and checklists are used for each transfer. Only trained personnel are permitted to load or unload material. • Preventative Maintenance: The Site's preventative maintenance program includes inspections of bulk storage tanks, loading stations, transfer piping, spill containment structures, high level alarms, critical process equipment and instrumentation. DOW CONFIDENTIAL - Do not share without permission • Inspections: I he site's Environmental, Health and Safety team conduct monthly inspections of the stormwater outfall as well as semi-annual inspections for the qualitative monitoring requirement. • Personnel Training and Instruction: All process operators receive basic environmental awareness and safety training before beginning specific process training. A qualified operator must train all process operators before they are allowed to operate any process alone. Corporate policy requires standard operating procedures (SOPs) for process operations. • Production Areas: All production operations are conducted in enclosed buildings. • Particulate Emission Control: All processes handling particulates have dust collectors to control particulate emissions. All dust collectors are part of the Site's preventative maintenance program • Housekeeping: Housekeeping inspections are conducted monthly by each production building. This helps to ensure the areas are maintained properly and to prevent safety hazards. • Security: All buildings are locked and there is limited access to the production buildings due to established badge accessible fenced in areas. • Erosion Prevention and Control: Parking areas are concrete and asphalt. The remaining ground is covered with grass, shrubs, and trees. Landscaping and contouring of the site grounds have been utilized to minimize run-off of stormwater from non-production/storage areas into active chemical usage and storage areas. DOw CONFIDENTIAL - Do not share without permission Dow Silicones Corporation Greensboro, North Carolina Stormwater Permit NCS000077 Significant Changes in Industrial Activities January 2019 Significant Changes: Our parent company is in the process of closing this facility. In the process of the shutdown, the following significant changes have been implemented or are in process: Closure of Building#5: All production activities have ceased in Building #5 on the site. All production equipment has been moved out and transferred to other sites within the company. The three above -ground storage tanks (AST's) that were located at this building were professionally cleaned and removed from the site. The secondary containment structure was then cleaned and decommissioned. The building is now idle. • Reduction of headCOUnt and production (sitewide): Due to the impending closure of the site, headcount has been dramatically reduced, thereby reducing the production output of the two remaining production buildings. This reduction is due to transfer of equipment and processes to other facilities within the company. • Reduction of inventory: Inventories of both raw materials and finished goods have been greatly reduced, thereby significantly reducing shipping, receiving and storage of chemicals and the associated risks of handling these products. • Discontinuation of the use of Xylene in manufacturing: The use of Xylene in manufacturing was discontinued late in 2018 when the process in which it was used was transferred to another site within the company. • Decommissioning of Above -Ground Storage Tanks (AST's)- Two (2) AST's were decommissioned, cleaned and removed from Building #1 and the secondary containment was cleaned and decommissioned. Five (5) AST's were decommissioned, cleaned and removed from the north tank farm at Building #3. More tanks are still in use in this tank farm, but will be decommissioned in the coming months. Two (2) 6,000-gallon AST's and one 8,000-gallon AST were decommissioned and cleaned at the tank farm to the west of Building 3. The tanks are still in place, waiting for disposition, but are not in use. All associated piping and utilities have been removed.
