The AST was installed on March 3, 2000, to

13、 extend the operating time of the emergency power generator.The following physical changes will materially affect the facilitys potential to discharge oil and will be made within six months of the Responsible Managers signature per 40 CFR 112. Within 6 months of the implementation of the following p

14、hysical changes, the SPCC plan will be amended to reflect the changes, and a Professional Engineer will certify amendments in accordance with 40CFR Part 112.5(c). In addition, various improvements will be made to enhance spill prevention practices at this facility. The following will be implemented:

15、1.1.The overflow protection line will be installed for the day tanks to return diesel fuel oil to the AST. This is necessary in the event the float pump in the day tank malfunctions and does not stop pumping fuel when the day tank reaches capacity. Without the return line, the generator shed would n

16、ot provide adequate secondary containment for the overflow.2.If a leak developed in the day tanks, as installed, fuel would not stop pumping diesel fuel oil from the AST. The generator shed does not provide adequate secondary containment for that quantity of fuel oil. Leak detection devices will be

17、retrofitted to automatically shut off the pump.Both items 1 and 2 would apply during “emergency operation only. See Section G for further discussion.2.A tanker truck unloading rack meeting the regulatory requirements will be installed. The curbing containment should be sufficient to contain the capa

18、city of a 4,000-gallon fuel service truck in accordance with 40 CFR Part 112.7.4.3.The existing training and inspection program will be documented within the NWS files and maintained as described in Section K. 6.A second high-level alarm (high-high alarm) set at 90 percent capacity (assuming the exi

19、sting high level alarm is maintained at 85 percent capacity) should be installed. Another alternative to make the tank more fail-safe is to install an automatic shut-off valve in the fill pipe set to close at 90 percent capacityC.SPILL HISTORY 112.7(a)This facility has not had a reportable spill.Sho

20、uld this facility have a reportable oil spill greater than 1,000 gallons in a single spill event or two reportable spills within any 12-month period, this SPCC plan and a report as outlined in 40 CFR Part 112.4 will be submitted to U.S. Environmental Protection Agency, Region 4 Administrator and the

21、 state agency in charge of water pollution control activities within 60 days of the incident(s).D.POTENTIAL SPILLS - PREDICTION AND CONTROL1.Facility Description The facility is located in the northern most portion of the NAS property at Boca Chica, Florida (Figure 1). The facility is about 7 miles

22、northeast of Key West, off Highway 1 and approximately 600 feet from the Atlantic Ocean. Figures 2 and 3 shows the layout of the facility, including the location of the diesel fuel oil AST and adjacent generator shed. The generator shed houses the 80-kilowatt emergency backup power generator and the

23、 two diesel fuel oil day tanks (two manifolded, 225 gallons each). The AST supplies diesel fuel for the generator. A float pump in the day tanks allows them to be refilled automatically through aboveground piping from the AST.The J&S Services Oil Company, a local commercial supplier, periodically fi

24、lls the AST. The estimated annual fuel usage is approximately 500 gallons. This estimate is based on testing the generator once per week for 30 minutes. Fuel consumption would increase based on the frequency and duration of any power outages.2.Prediction of Potential Spills 112.7(b) The AST is locat

25、ed on a concrete pad at the facility. The day tanks are located inside the generator shed. Small spills or leaks breaching the tanks secondary containment systems (described in paragraph D.3.) would flow in one of two directions because of the slope of the area and the presence of the large berms on

26、 the west, south, and east sides of the facility. Fuel oil spilled would flow to the west until it encountered the limestone berm, then northward along a very slight slope. As a result of the flat topography and sandy soils of the surrounding property, a small spill would most likely be contained at

27、 that point. A leak or spill from the AST could possibly drain into manmade ponds about 50feet north and 180 feet northeast of the site. Those ponds drain via corrugated metal culverts into wetlands to the north. There is a pond (a former borrow area) about 110 feet to the south, but because of the

28、large berms at the NEXRAD site, storm runoff does not flow to the south. The most probable cause for a spill from the AST is from overfilling. The most probable cause for a spill from the day tanks is malfunction of the pump float switches (only during emergency operation, see Section G). Table 1 su

29、mmarizes the potential failure types, potential spill volumes, estimated rates, and direction of spill flow.TABLE 1POTENTIAL SPILL SOURCES AND VOLUMESSourceEventPotential Spill Volume (gallons)Estimated RateDirection of Spill FlowRemarks1,000-gallon ASTOverfilling50 to 6050 to 60 gallons per minuteN

31、orthPossible only during emergency operation (See Section G)3.Spill Controls 112.7(c) Appropriate containment and diversionary structures and equipment to prevent discharged oil from reaching navigable waters have been installed for the AST. The AST is a double-walled rectangular tank, encased in co

32、ncrete (Convault). Attachment 1 provides the manufacturer detail on the construction of the AST.A float-type level gauge visually indicates the fuel level, and low- and high-level alarms are audible outside and in the control room. The high level alarm is set at 85 percent of the AST capacity (850 g

33、allons). In addition, an automatic shutoff valve is housed in the fill pipe and set to stop the flow of fuel into the tank at 90 percent capacity (900 gallons).The day tanks are totally enclosed inside the generator shed, protected from the elements. Physical components of the shed floor and the day

34、 tanks provide adequate secondary containment. These tanks are also fitted with two redundant float switches that shut down the pump that moves fuel from the AST to the day tanks. These switches are set to stop the pump at 80 and 90 percent capacity during emergency operations (See Section G.)This f

35、acility has found it practicable to install equipment and/or structures to prevent discharged oil from reaching navigable waters in accordance with 40 CFR Part 112.7(d); therefore, an oil spill contingency plan that follows 40 CFR Part 109 is not required. The facility maintains spill response suppl

36、ies (for example, 100 pounds of granular oil absorbent, oil absorbent pads, a broom, and a shovel) to contain and quickly remove small leaks or spills. Local oil spill cleanup support will be provided through NAS resources, which will respond in case of a spill that exceeds the facilitys management

37、ability.E.FACILITY DRAINAGE 112.7(e)(1)The emergency power generation day tanks are housed inside an enclosed building with a concrete berm used as the footing for the building. The floor dimensions for the generator building are 15 feet 2 inches by 10 feet. The berm height inside the building is 12

38、 inches. No drainage from this building is designed or planned. The AST does not require secondary containment since it is double walled. Small quantities of storm water may accumulate in the interstitial space between the tanks. The facility uses positive means to manage this storm water to prevent

39、 an oil spill. Any storm water observed in this interstitial space during monthly inspections is pumped out, collected, and inspected for a visible sheen before it is drained to the storm water system. Inspection procedures are discussed in Section F.Storm runoff from the developed portions of the N

40、EXRAD site drain into the two manmade ponds about 50 feet north and 180 feet northeast of the site. Those ponds drain via corrugated metal culverts into wetlands to the north. Storm runoff does not flow to the south because of the limestone berms at the NEXRAD site. According to the U.S. Department

41、of Agriculture (USDA) Soil Conservation Service (SCS) “Classification and Correlation of the Soils of Monroe County Keys Area Florida published in January 1989, soil at the NEXRAD site is Cudjoe marl, tidal. The former missile shelter and concrete foundation have been removed, and the elevation of t

42、he site has been raised to 11 feet above mean sea level (msl) (1foot above the 100-year flood level). The existing berms around the west, south, and east sides of the site were retained to provide control of sheet flow. Good management practices to include inspections, personnel training, and readil

43、y available spill response supplies will prevent oil from reaching navigable waters in the event of equipment failure or human error at the facility.F.BULK STORAGE TANKS 112.7(e)(2)The AST and the day tanks are constructed of material compatible with the product stored. The AST provides sufficiently

44、 impervious polyethylene and concrete secondary containment. The floor of the generator shed will provide adequate secondary containment for the day tanks, pending upgrades (see Section B.1. through B.2.). The AST is bolted to its concrete foundation.The AST and the day tanks as well as their founda

45、tions are visually integrity tested through monthly inspections for signs of deterioration and leaks that might cause a spill. The accumulation of oil in the interstitial space of the AST is also inspected. Any storm water observed in this interstitial space is manually drained out, collected, and i

46、nspected for a visible sheen. Any visible sheen is removed using absorbent pads before it is discharged. Documented records of these inspections and storm water discharges are kept on site for a period of 3 years. Copies of the inspection form are provided in Appendix A.There are no buried, partiall

47、y buried, internally heated, mobile, or portable tanks located on this facility.The AST is engineered with a direct vision float-type gauge to indicate the fuel level. As backup, the AST is stick-inventoried before unloading occurs, and operators continuously monitor unloading operations. Any leak is investigated to determine the cause of the leak, and corrective actions are taken as appropriate. Table 2 presents a descriptive inventory of the bulk fuel tanks.TABLE 2DESC
