NJ0025411 1 DRAFT NJPDES PERMIT

Dear Mr. DeWan:

As you are aware, Public Service Electric and Gas Company (PSE&G) sought authorization to participate in the " Write Your Own NJPDES ("' Permit" Program on December 31, 1993. By letter dated February i 18, 1994, you granted PSE&G's request. PSE&G herein submits a ] x Draft NJPDES Permit and Fact Sheet / Statement of Basis for the Hope Creek Generating Station, NJPDES Permit No. NJ0025411, in accordance with that authorization. The Draft NJPDES Permit and Fact Sheet / Statement of Basis were developed in accordance with che guidance and regulations of the Department and the best pollution prevention methods for the 4 operating facility. The major initiatives proposed include: resolution of the thermal limitations on the cooling tower blowdown effluent consistent with the capabilities of the cooling tower and the applicable regulations; proposal to reroute the effluent from the Sewage Treatment Plant (DSN 462B) to the cooling tower j blowdown effluent (DSN 461A), within one year of the effective date of the permit, to provide treatment of residual chlorine without the use of additional chemicals; development and implementation of a Stormwater Pollution Prevention Plan (SPPP) for stormwater outfalls (DSNs 462A, 463A and 464). This Plan () incorporates Best Management Practices to control

+; t MAY 05199L f y: R.' DeWan-2 $_j LR-E95053 1 i and abate the discharge of pollutants in stormwater runoff and replaces numeric limitations and. monitoring requirements. The requirement to prevent pollution from occurring in the first place, as opposed to requiring. treatment or control'once pollution has occurred, is generally more protecti"e of public health and-natural resources, and therefore as, if not more stringent than, numeric limitations; and, conduct of an Acute and Chronic Toxicity Study to demonstrate that the effluent does not exceed State Water Quality Standards for toxicity. These Studies are proposed after the Sewage Treatment System reroute is completed to provide the most representative evaluation of the effluent. PSE&G appreciates this opportunity to work cooperatively with the Department. If you or any members of your staff have any questions on this submittal, please contact Mr. Frank X. Thomson, Jr., Manager - Licensing and Regulation, at (609) 339-1229 or Mr. i Edward J. Keating at (609) 339-5430.

DESCRIPTION OF FACILITI The above-named applicant has applied for a renewal of New Jersey ' Pollutant Discharge Elimination System (NJPDES) permit Number NJ0025411, to the State of New Jersey Department.~of Environmental } l -Protection (NJDEP), Division of Water Quality to discharge into the. f designated receiving water. l t The Hope Creek Generating Station (HCGS) is located on - the l l southwestern side of Artificial Island on the eastern shore of the j Delaware River (River) in Salem County, New Jersey. HCGS lies j about 50 miles northwest of the mouth of the Delaware Bay and 30 O miles southwest of Philadelphia (See Figure 1). The River in the area of HCGS is approximately 2.5 miles wide. The tidal flow of the River past HCGS is approximately 400,000 cubic feet per second j or 259,000 million gallons per day (MGD). A location map of the facility is included as Figure 1. HCGS consists of one boiling water nuclear reactor with a net electrical generating capacity of approximately 1,067 megawatts which commenced commercial operation on December 20, 1986. HCGS operates with a closed cycle cooling system which uses a natural draft cooling tower. Makeup water is provided to the cooling tower i from the River and is returned to the River as cooling tower blowdown, with some evaporative losses to the atmosphere. The O i DRAFT FOR DISCUS $10N PURPOSES ONLY

Fact Sheet / Basis Permit No. NJ0025411 Page 3 of 67 Pages fm e s Schematic of Water Flow is shown in Figure 2. Condenser cooling water is treated to remove heat by circulation in an evaporative natural draft (counter current) cooling tower. Sodium hydroxide is added to the cooling water to protect the tower fill from chemical deterioration and sodium hypochlorite is added to prevent biofouling of the condensers, the cooling tower, and related equipment. A portion of the recirculated cooling water, referred to as cooling tower blowdown, is continuously removed to prevent solids buildup. The cooling tower blowdown is treated with ammonium bisulfite, a dechlorinating agent, to reduce chlorine residuals to permitted levels prior to discharge. Makeup water is ( provided to the cooling tower from the Delaware River through the service water system to replace the water removed through blowdown and evaporative loss to the atmosphere. Cooling tower blowdown is discharged through outfall DSN 461A. DSN 461A is the largest discharge from HCGS, and primarily consists of cooling tower blowdown (40.5 MGD) with minor waste stream contributions from the Low Volume and Oily Waste System (DSN 461C) and liquid radioactive waste system (DSN 461B) as shown in Figure 3. Sediment which collects in use cooling tower basin is removed as necessary and is disposed of at an onsite dredge spoil area.

The liquid radioactive waste (LRW) system is designed to process liquid waste streams from inside the power generation facilities that may potentially contain radioactivity. The treatment system contains all necessary equipment to meet both U.S. Nuclear Regulatory Commission (USNRC) standards for the discharge of radioactivity and the applicable New Jersey State Water Quality Standards. The USNRC has issued license number NPF-57 to the facility. The Low Volume and Oily Waste (LVOW) System (DSN 461C) is an internal monitoring point which ccmbines with cooling tower blowdown prior to discharge. The LVOW System collects and treats potentially oily wastewater from area, building, and equipment drains throughout the site as well as the auxiliary boiler blowdown and miscellaneous stormwater sources. Collected waste streams are processed througn an API-approved oil water separator as shown in Figure 4 where solid and floatable materials are removed. Settleable solids are removed from the waste stream by gravity separation and are transferred to the oily sludge holding tank before being trucked of f-site to a licensed disposal facility. Oil and floatables removed by the separator are routed to the waste oil tank before being trucked of f-site to a licensed disposal facility.

The sewage treatment plant (DSN 462B) also discharges through this outfall but is monitored independently. Due to facility elevations and the proximity to the b River, this outfall is tidally influenced. The Sewage Treatment Plant (DSN 462B) treats sanitary wastewater collected from the Salem and Hope Creek stations and administrative facilities and se. 2 holding tank waste generated at unconnecteu buildings onsite. Collected wastewaters receive secondary treatment in a single channel oxidation ditch which oxidizes the organic constituents of the influent wastewater. Solids are then removed in two clarifiers with a portion of the sludge (biosolids) recycled back to the oxidation ditch. Clarifier effluent can then be polished in sand filters for removal of any fine solids. Final effluent (0.03 MGD) is chlorinated to destroy pathogenic organisms prior to discharge to the Delaware River through DSN 462A as shown l v DRAff - FOR DISCUS $10N PURPOSES ONLY

The Salem Soil Conservation District reviews and approves a soil erosion and sediment control plan for all construction projects which disturb more than 5,000 square feet of land (or more than 1,000 square feet of land within 25 feet of a stream bank). Due to facility elevations and the proximity to the River, this outfall is tidally influenced. The chlorination structure drains from the sodium hypochlorite tank secondary containment and the chlorination control building are normally isolated and residual chlorine shall be verified to be below detection prior to release through this outfall. The Perimeter Storm Drain (DSN 464) collects precipitation runoff from several non-process areas on the Hope Creek site and access roadways as well as natural drainage from the adjacent marshes and then discharges to the Delaware River (0.23 MGD).

The Department is currently developing a watershed-based approach to WQBELs for pollutants, including toxic pollutants. Until such time as those limitations are developed for Zone 5, toxic pollutant limitations for most dischargers are determined using technology based limitations and miscellaneous effluent requirements along with a whole effluent toxicity limitation, when necessary. In 1 addition, WQBELs for toxic pollutants from most dischargers will be imposed and/or revised as necessary when Total Maximum Daily Loads i (TMDLs) are developed on a watershed specific basis.

The terms and conditions of the existing permit were developed and imposed prior to the Station's beginning operation in 1986. The I permit required that Hope Creek operate with a closed cycle cooling water system and imposed effluent limitations on the cooling tower blowdown discharge based, in large part, on the generic design characteristics for the type of cooling tower proposed for installation. O In 1990, the Permittee entered into an Administrative' Consent Order (ACO) with the Department to resolve, among other matters, certain violations of the effluent temperature and heat limitations from DSN 461A, the cooling tower blowdown discharge. In connection with the establishment of the terms and conditions of the Aco, the permittee presented the information and data to the NJDEP which had been used to develop the pre-operational permit limits. A review of this data suggested that the limits were based on the efficiency of the cooling tower under average meteorological conditions and certain station operating conditions. As a result, the NJDEP established interim limits in the ACO for Heat Rate but required a year long study of the cooling tower blowdown DRAFT - FOR DISCUSSION PURPOSES ONLY - ~

i i Fact Sheet / Basis Permit No. NJ0025411 Page 35 of 67 Pages %/ relative to various operating conditions to confirm the initial conclusions and to determine appropriate limits based on the efficiency of the cooling tower. The permittee submitted the results of the cooling tower blowdown study to the NJDEP in 1991. This study concluded that under certain meteorological and plant operating conditions, the cooling tower performance was such that the limits in the existing permit could not be met. P In connection with the development of a supplement to its permit renewal application, the permittee commissioned an additional study of the effects of meteorological conditions which have occurred at the site on cooling tower performance under varying operating conditions. This study concluded that meteorology and intake flow have the greatest effect on the Heat Rate and the Effluent Temperature. Based on the results of this study, the permittee has proposed less stringent limitations for Effluent Temperature and seasonal Heat Rate. In addition, the permittee commissioned a study to determine whether the proposed effluent limitations it was 1 seeking would result in compliance with applicable water quality standards for temperature. The results of a mathematical computer model depicting the thermal discharge demonstrated that even with the proposed limits, the thermal plume from Hope Creek Generating Station does not exceed 1.5* F AT from June through August or 4* F AT from September through May at the edge of the Heat Dissipation Area designated for thermal discharges from Hope Creek.

Proposing these limits'is in accord with the anti-backsliding provisions of federal and state law for the following reasons: (1) the permittee has installed a j natural draft cooling tower with the design contemplated at the j time the existing permit limits were established and has properly [ operated and maintained the cooling -tower. Nonetheless, the permittee has been unable to achieve compliance with the limitations imposed due primarily to meteorological conditions, which are clearly beyond the permittee's control.

This modification would provide additional treatment, e.g. residual chlorine would be removed prior to l discharge through reaction with the cooling tower blowdown dechlorination chemical, ammonium bisulfite. The Department supports this proposal as it provides treatment without additional chemical additions. This modification is anticipated to require one year to complete.

These measures included: (1) regrading the facility and installation of gravel and seeding of grass on areas which were previously in a natural state to reduce drainage velocity and more equally distribute precipitation runoff; (2) installation of inlet protection on all stormwater collection catch basins to minimize solids entrainment; and (3) installation of check valves on the North and South Yard Drain outfalls to reduce tidal intrusion. As part of the requirements of the ACO, the permittee also conducted a stormwater study at the facility to determine the feasibility of obtaining representative stormwater samples for analysis. The permittee, in the stormwater V study dated July 13, 1990, concluded that it was infeasible to collect representative stormwater samples at the facility based on the tidal intrusions into the existing stormwater conveyance system from the Delaware River. The stormwater study demonstrated that representative monitoring of stormwater could not be achieved with the existing conveyance system elevations due to tidal intrusion in the system by Delaware River water. The permittee submitted a BMP Plan to the Department dated February 28, 1990 and supplemented this plan with additional information dated January 31, 1992 in order to satisfy additional requirements of the ACO.

O As a result of the implementation of the capital projects and the BMP required under the ACO, the average TSS values reported on Hope Creek Generating Station's DMRs since 1992 have consistently been lower than the values reported prior to the installation of the capital projects and the BMP. The NJDEP's Bureau of Stormwatet Permitting and the Bureau of Standard Permitting have inspected the site and have determined that continued use of BMPs instead of numeric limits is the most appropriate means of regulating the discharge of pollutants from this site in stormwater runoff.

The BMPs are proposed to control and abate the discharge of pollutants into the stormwater runoff. The Department finds that the continuance of numeric effluent limitations and monitoring conditions is unwarranted and infeasible based on the following: 1) the tidal intrusion of the Delaware River into the facility's stormwater conveyance system reported in the stormwater study submitted by the permittee in 1990; and 2) the material and substantial changes at the facility implemented between 1989 and p 1992 through its capital improven.ent projects and implementation of G BMPs such as minimization and climination of contact of source materials with stormwater runoff. The SPP Plan proposed in this draft permit will expand upon these BMPs by instituting a number of management practices to ensure that proper stormwater operations, maintenance procedures, and good housekeeping practices are implemented at the facility to minimize the contact between stormwater runoff and the facility's opera': ions.
