Strickler, Manager Environmental Protection & Industrial Safety Nuclear Fuel & Components Manufacturing General Electric Company P.O. Box 780 Wilmington, North Carolina 28402 SUBJECT: Request for Designation of Substantially Identical Stormwater Dutfalls Dear Mr. Strickler: Your request dated July 19, 1991, for a determination that stormwater effluents from certain outfalls on your site are substantially identical at the Wilmington General Electric facility, has been reviewed by members of the Water Quality Section staff. You requested that outfall #9 be considered typical of outfalls 1-8, 11, 12 and 17 and outfall #14, containing runoff from road segments B and C, be considered representative of the stormwater runoff from the access road segments A, D, and E. In addition to the above sampling locations and per your discussions with Coleen Sullins, it is my understanding that the stormwater outfall from the western most portion of the site associated with the waste management areas (see attached Figure S) will also be sampled for your permit application. Additionally, it is my understanding that the stormwater drainage associated with the bulk storage on the western side of the FMO facility, is captured and treated in your process waste treatment facility and therefore is not expected to be discharged into outfalls #17 or #12.

The developed portions of the facility encompass approximately 342 acres. Undeveloped portions of the facility, encompassing over 1300 acres, are primarily forest or tidal areas. The attached Site Drainage and Significant Materials Map (Drawing No. 8002E99) presents the location of the industrial activities, stormwater drainage structures, drainage areas, outfalls, building locations, and roads for the developed portions of the facility-. The GE Wilmington facility- is bordered on the east by NC Highway 133, on the south by Interstate 1140, on the west by the Northeast Cape Fear River and on the north primarily by undeveloped foresdand. There are residential subdivisions to the northeast and southwest. Stormwater discharges to two receiving water bodies: the Northeast Cape [Fear River and Prince George Creek. Neither is shown on the site map due to their distance from the developed portion of the facility. The Northeast Cape hear River, located less than 1 mile west of the developed portion of the facility, receives the majority of the stormwater runoff, a5 well as treated process and sanitary wastewaters permitted under NPDES Permit No. NC0001228. Prince George Creek, located approximately 5 miles north of the facility, receives stormwater runoff from the eastern portion of the facility. "!here are seventeen storm water outfalls/drainage basins (1, 2, 3, 4, 5, G, 7, 8/81, 9, 10, 11, 12, 13/ 13i, 14, 15/ 15i, 16 and 18) for the developed areas of the facility. It is noted that there is no Outfall 17. Representative outfall status was granted by NC D%X'Q in a letter dated ,August 13, 1991 such that Outfalls #9, # 13, and # 14 were considered representative of all stormwater outfalls at the facility. Prior to the last permit renewal, the Outfall 1 drainage basin was redesigned and, with the last permit renewal, replaced Outfall 14 as representative of the roadways and on -site parking. Table 1 identifies the latitude and longitude, total drainage area, total imperc-ious area, and receiving water bode for each outfall. Table 2 presents the significant materials at GE Wilmington. These potential stormwater sources are numbered bv outfall and are shown on the Site Drainage and Significant Material Map (Drawing No. 8002E99) using the source numbers from the first column of Table—1. 61 Usungion. - N11DI ti StO=Uiu t:'r llvrmt R=m 3l Section 1 Page 1-1 Table 1 Drainage Basin Areas Outfall number Latitude Longitude Total area (acre) Impervious area M Receiving water 1 34" 191211 -77055'27" 39.8 33 Prince George Creek 2 34019'15" -77055'28" 7.9 18 Prince George Creek 3 34019' 19" -77055'29" 2.8 41 Prince George Creek 4 34019'26" -77055'36" 6.2 92 Prince George Creek 5 34019'27" -77055'41" 4.6 18 Prince George Creek 6 34019'24" -77055'45" 1.3 68 NE Cape Fear River 7 34019'24" -77055'45" 4.9 100 NE Cape Fear River 8 8I 34019'25" 34019'26" -77055'45" -77055'48" 20.6 82 NE Cape Fear River 9 34019'28" -77"55'58" 37.7 55 NE Cape Fear River 10 34019'38" -77°564" 1.6 20 NE Cape Fear River 11 34019'33" -77056'1" 4.1 55 NE Cape Fear River 12 3401939" -77056'1 1" 21.4 48 NE Cape Fear River 13 34019'45" -77056-29" 66.7 23 NE Cape Fear River 14 34019' -77055'30" 6.0 36 Prince George Creek 15 3401931" -77055'37" 3.7 51 Prince George Creek 16 34:19'36" -77--56'51" 20.3 13 NE Cape Fear River 18 34319'46'" -77--56'8" 16.1 9 NE Cape Fear River The following Outfalls are defined by the permit for sampling purposes.

The permit requires analytical monitoring at three representative outfalls (#9, #13, and #14), on a semi-annual basis, for the entire duration of the permit. Samples were taken during a representative storm event. That is, grab samples were collected during discharge of a rainfall event greater than 0.1 inches and preceded by at least R2 hours in which no precipitation greater than 0.1 inches occurred. The following parameters and storm characteristics were monitored I. Lead, total recoverable (mg/L) I Non -Polar Oiland Grease (mg/L) 3. Total Suspended Solids (mg/L), 4. pl-I (standard units) 5. Total Rainfall (inches) These values were reported to the Division on semi-annual Stormwater Discharge Outfall (SDO) Monitoring Reports as required by the permit. For convenience, parameters 1-5 are summarized on Table 3 for each of the monitored outfalls. .Additional monitoring for vehicle maintenance activities is not required for GE Wilmington because the site does not use more than 55 gallons of new motor oil per month when averaged over the calendar }'car. GU conducts ongoing monitoring of it new motor oil usage to ensure that it is below the threshold, and thus, exempt from additional monitoring. ('A.

There is a minimum of 60 days between ant - two monitoring events. Visual observation is conducted of the following characteristics: color, odor, clarity, floating solids, suspended solids, foam, oil sheen, erosion and any other indicator of stormwater pollution. -1-0 facilitate the visual monitoring inspections, placards have been posted at all stormwater outfalls. This ensures consistent location evaluation during visual monitoring, outfall inspections, and non-stormwater discharge assessments. Semi-annual outfall visual monitoring events are tracked in the Compliance Calendar. I1us program alerts the GE owner of the task that the visual monitoring must occur, and the task remains "open" until completed and closed in the system. The completed visual monitoring results are maintained in thatyear's S%X,`PPP binder. The subsequent pages summarize the semi-annual visual monitoring results by outfall from December 2014 through December 2017. As of this submittal, the 1 H 2018 qualitative sampling has not been performed. The information has been summarized in the table based on inspection reports and work order documentation. Values greater or equal to 3 are investigated and documented in the S\t'PPP for that year.

The structural controls (e.g., containment, dike, curb, and/or roof) and management practices employed at the individual significant materials at G1 Wilmington are listed in Table 2 in the Supplemental Information Section No. 1. The site -vide B.NIPs that are utilized by GC Wilmington are described in this section and include: => Good Housekeeping, =:� Inspections/Preventative Maintenance Program, => Outside Material Storage/Tanks/Secondary Containment, => Material Handling, => Spill Prevention and Response, => Seger and Outfall Identification, and => Employee Training. Good Housekeeping GI : Wilrnington maintains a clean and orderly facility through implementation of a variety- of programs, practices, and procedures, including: ■ Regular pickup and disposal of garbage and debris ■ Routine inspection for leaks ■ Proper material container storage practices ■ Identification and labeling of all chemical substances ■ Disposal of old equipment and used chemicals These housekeeping practices help to reduce waste and pollutant generation as %veil as the potential for spills and leaks. Ins ections Preventative Maintenance Program The preventive maintenance program at GC Wihriington ensures that the stormwater control facilities are clean and operating effectively. The program consists of visual inspection, cleaning, and repair activities. inspections are conducted at the stormNvater controls and the significant materials identified on the Site 'Map and 'fable 2 in the Supplemental Information Section No. 1. At a minimum, these inspections are conducted semiannually-. Upon 01 \N dmmgwn—\PD1-1; Storm-4 atet Pcrmt Rmot A Section -1 Page 4-1 completion of the inspection, anv cleaning and repair activities, if needed, are documented. Completion of die inspections, cleaning, and repairs are tracked electronicaflv. Specific inspection areas include: ■ Material handling and storage areas ■ Secondary- containment areas ■ Stormwater outfalls ■ Catch basins and trench drains ■ Roofs and corers ■ Potential spills and areas of possible contamination Outside Material Storage/Tanks/Secondary Containment GE Wilmington's practices and activities related to outside material storage areas and aboveground tanks are in place to prevent or minimize contact of significant materials with stormwater. Many material storage areas are covered and/or have containment curbing or grading. Aboveground tanks are in compliance -,,.-ith federal and state laws for containment, integrity testing, overflow protection, and protective guards. Stormwater retained by the curbing or dikes is visually inspected for contaminants prior to release. 131\1Ps currently in use: ■ Provide secondary containment for liquid storage ■ Provide containment curbing, dikes, and/or grading ■ Cover materials to eliminate exposure to stormwater ■ Store materials on pallets or racks ' Visually inspect stormwater retained by curbing/dikes/ containment prior to release • Move storage areas inside if possible Material Handlin \laterial loading and unloading is typically conducted in areas designed to reduce potential contact with stormwater. Loading areas for bulk chemical transfers are either: (1) contained to allow visual inspection of stormwater prior to release, or '2) are graded to direct stormwater to the process drain system for treatment prior to discharge. The stormwater is contained during transfer operations by secondan• containment, curbing, grading, trays, and/or drain covers. Further, manual rah es in the closed position have been installed in select storm drains. Direct pipeline transfers are in place for several materials and waste streams. This method of material transfer greatly reduces the potential of stormwater contamination. There are detailed written guidelines on loading and unloading procedures in the Spill Prevention Control and Countermeasures Plan. Shill Prevention and Response W U4mmKton Section Page 4-2 GE Wilmington has written procedures on spill prevention and response. These procedures describe the protocol of responding to a spill and the individuals at the site who should be contacted. The procedures are included in the facility Spill Prevention Control and Countermeasures Plan and in the Radiological Contingency and Emergency Plan. Site staff are trained on spill prevention and response. Employee Training The Employee Education and Training Program is designed to familiarize key employees with the intent and components of the Stormwater Pollution Prevention Plan. Training is provided for employees involved in operations with the potential to affect stormwater. Topics included in the training session include: ■ General stormwater awareness ■ Flow to use the Stormwater Pollution Prevention Plan ■ Chemical spill response procedures ■ Preventative maintenance ■ Inspection procedures ■ Materials management practices ■ Good housekeeping measures Sewer and Outfall Identification "1liere are three separate drainage collection systems at the facility: process wastewater, sanitary wastewater, and stormwater. Sewer manhole covers and catch basins have been color -coded to distinguish between these systems. Also, as described previously, placards have been posted at all stormwater outfalls. -11-11s ensures consistent location evaluation during visual monitoring, outfall inspections, and non- stormwater discharge assessments.
