NLS ab60,3 DOC TYPE ❑ FINAL PERMIT ❑ MONITORING INFO ❑ APPLICATION ❑ COMPLIANCE K OTHER DOC DATE ❑ i qq L t lool YYYYMMDD The purpose of this document is to provide a comprehensive description of the means and methods used by South Atlantic Services, Inc. to comply with North Carolina General Statute 143-215.1 concerning the safe discharge and movement of stormwater generated at our facility. The facility is located at : South Atlantic Services, Inc. US Highway 421 North Wilmington, NC New Hanover County Current Permit No: NCS000084 Effective Date: October 1, 1994 A. SITE PLAN 1) General Location Map - see Attachment 1 2) Storage Practices a) All storage tanks are non -pressurized and constructed of either carbon steel, stainless steel, aluminum, or polypropylene depending on the product being stored. b) All tankage is above ground and diked. c) No product shall remain outside unless it can be covered or has secondary contaiment. d)Wood pallets are allowed to be stored outside only if there is no chemical residue present. e) All usable paper, plastic, and cardboard items shall be stored inside. Only items that are segregated for recycling purposes shall remain outside and they shall be properly secured. f) No gas,LP, or electric lifting devices g)No rail cars shall remain pressurized shall remain outside overnight. or hooked up until prior to usage. 3) Loading and Unloading Activities a) .All freight trucks are loaded and unloaded under covered docks. b) All chemical bulk trucks are loaded and unloaded in dyked areas with an attendant present at all times. These are done outside in an uncovered area. c) Some but not all rail cars are loaded and unloaded in uncovered areas depending on the product. Some of the uncovered areas have containment areas and there is a catch pan on site that can be placed under cars if necessary. 4) Oudoor Process Areas - There are no outdoor process areas other than the above mentioned process areas. 5) Waste Disposal Practices - All human waste is handled by an on -site septic system . All other trash and waste is handled by a local waste management facility. 6) Site Map - see Attachment 2 7) Outfalls and Potential Pollutants a) Outfall No. 1 - Only rainwater from roof top of Building No. 8 b) Outfall No. 2 - Rainwater from rooftop of Building No 6 and off top of the blending sheds. Also contained in this outfall area are above ground storage tanks containing the following: Antifreeze, Caustic Soda 50%, Potassium Hydroxide 45%, Phosphoric Acid 7 5 %, Sodium Tolyltriazole 50%, Tween 20, Maleic Anhydride, Sulfuric Acid, Hydrazine 40%, Ethylene Glycol, and mixtures of Octanol, Decanol; Maleic Hydrazide and water. All of these tanks are dyked and are exposed to stormwater. 8) Significant Spills or Leaks - No significant spills or leaks have occurred at the facility in the past 3 years. B. STORMWATER MANAGEMENT PLAN 1) Tanks a) All tanks have a retaining dyke wall around them in the event of a tank rupture or overfill. The dykes are designed to hold 125% of the volume of the largest tank in the dyke. b) A large majority of the tanks have overfill alarms on them to warn operators of safe filling levels. These are checked on an annual basis for proper operation. c) All tank levels are checked and inventoried daily. Any major discrepancies in the inventories are immediately investigated. Also, a visual inspection of the piping and overall assessment of the tank farm is performed daily. d) Any rainwater collected in the dyked areas is checked daily and discharged ONLY after checking for possible chemical residues. if anything other than rainwater is present or suspected to be present as evidence from a visual inspection, a sample is pulled and checked by the lab for pH and other properties. If evidence of contamination is connrmed, the rainwater shall not be discharged but rather is collected in appropriate containers and held for further analysis. The collected water is recycled back into usable product when at all possible. e) No underground tanks on site. 2) Processes a) All process vessels and mixing vessels have a retaining dyke wall around them. b) All process areas and loading areas are covered where feasible. c) All bulk loading stations are dyked. d) Any outside operations, such as drum filling from a tank truck or rail car, will keep an employee or supervisor present at all times. In addition, they will keep absorbent material readily available in the event of any spills. 3) Maintenance a) Any maintenance work performed on pumps or equipment will be done inside the shop or a covered area where feasible. b) Any hydraulic oil and other maintenance fluids are collected in a waste drum and appropriately disposed of off -site. Any process fluids collected from maintenance work on equipment will be recycled into product when possible. c) It is the responsibility of the Maintenence Supervisor to develop a preventative maintenance schedule for all equipment and forklifts. 4) General Housekeeping a) All spills are cleaned up immediately when and if they happen. Any spilled product is recycled back into good product when not contaminated. b) An inventory of spill control products are kept on hand at all times. Absorbent material specific to oils, acids, and caustics and appropriate neutralizing agents are used when necessary. c) All outside areas are policed once a week for trash. d) Dumpsters maintained on site for plant trash and garbage. Picked up at least twice a week. e) Cardboard and plastic items are segregated and picked up by local recyclers. 3. SPILL PREVENTION CONTROL & COUNTERMEASURE PLAN (SPCC ) - Maintained as a seperate document (available upon request) 4. EMERGENCY RESPONSE & CONTINGENCY PLAN - Maintained as a seperate document (available upon request) S. EMPLOYEE TRAINING a) Personnel involved with or responsible for proper spill response and cleanup procedures are trained on an annual basis. The training consists of review of MSDS and appropriate absorbent material and or neutralizing agents. Also, the operation and maintenance of equipment used to prevent discharges and significant changes in the types of products on hand are reviewed. Personnel have a combination of on-the-job training and continuing education classes. b) Responsible Training Officer - Walter Kennedy 6. RESPONSIBLE PARTY The person responsible for the overall coordination, development, implementation, and revisions of the Stormwater Pollution Prevention Plan for our facility is Walter Kennedy. 7_ PLAN AMENDMENT The plan shall be amended whenever there is a change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollutants to surface waters. The Plan is reviewed on an annual basis and updated as needed. 8. FACILITY INSPECTIONS a) To be performed at least twice a year by the Plant Manager. Usually is performed much more frequently during weekly drive arounds the plant_ These are not documented unless problems are noted. b) Visual Monitoring is performed for the following parameters: Color Odor Clarity Floating Solids Suspended Solids Foam Oil Sheen This monitoring is performed twice a year for each outfall. Results of these ' inspections are recorded on a form (See Attachment 3) o0 VIIAU tit' M5d I a o00 00 0 Sri►►• ... I • • � wrirehrnrso a Asf►hnll j� j I Aran nraincil Oy Onli,ill 1' 0 oo 3 11,3.
