Response to Comments Page 1 of 5 Permit No. NJ0025411 New Jersey Department of Environmental Protection Division of Water Quality Bureau of Point Source Permitting - Region 2 The NJ Department of Environmental Protection issued a draft NJPDES permit modification on August 17, 2000. Comments on this permit modification were received from the following:

Maureen Vaskis Office of Environmental Counsel PSEG 80 Park Plaza, T5C Newark, NJ 07101-1267 A -ummary of these comments and the Department's responses are as follows:

Fact Sheet Comment 1 Given slight differences in language in the Draft Permit Document, the specific requirements relative to when the stay is applicable are ambiguous. PSEG respectfully requests that the language proposed below be used in the final permit modification and that the NJDEP clarify through its response to comments that the language in the Draft Permit Documents should be interpreted consistently with this said language in the final permit modification.

At Section III, paragraph 1, line 7, the Fact Sheet provides that These conditions for the average wet bulb temperature and the relative humidity must occur concurrently for a time period of greater than 60 minutes for this temperature reporting requirement to apply.

PSEG proposes that this sentence read as follows:

These conditions for the average wet bulb temperature and the relative humidity must occur concurrently for a time period [ef] equal to or greater than 60 minutes for this temperature reporting requirement to apply.

Response 1 The Department agrees that its intent was for the proposed temperature reporting requirement to apply when the conditions for the average wet bulb temperature and the relative humidity occur concurrently for a time period equal to or greater than 60 minutes. The Department issued a stay letter on June 12, 2000 where the language included in such is consistent with this proposed language. As indicated in Response 7, this clarified language has been included in Part III-B/C of this final permit modification. However, the Department does not include a revised Fact Sheet

Response to Comments Page 2 of 5 Permit No. NJ0025411 in any final permit modification consistent with N.J.A.C. 7:14A-15.8. Therefore. this clarification is hereby noted for the Administrative Record.

Statement of Basis Comment 2 In the section heading on page 4 of 16, the dates shown in the section heading do not agree with the dates in the body of the text, which are the correct dates. The section heading presently states:

Background for Hope Creek's Cooling Tower Design Based on PSE&G's 11/15/99 & 6/2/200 Submittals The section heading should read as follows:

Background for Hope Creek's Cooling Tower Design Based on PSE&G's 11 /[4-4 17/99 & 6/2/2000 Submittals Response 2 The Department acknowledges that the correct dates for these two submittals are 11/17/99 and 6/2/2000 as indicated in the body of the text as well as on page 16 of the Fact Sheet. This clarification is hereby incorporated into the Administrative Record.

Comment 3 On page 10 of 16, paragraph 3, line 6 there is a reference to Table L.A-1. PSEG notes that none of the tables included in the Draft Permit Documents are identified as such. PSEG questions if this is a reference to Table I on page 7 or to another table.

Response 3 This sentence reads as follows "These results are consistent with actual measurements of ATHccT for July 1999 (Table I.A. - 1)." This reference to Table L.A-1 was intended to mean Table 1 which shows hourly data for various parameters on July 5, 1999. Table I has been included as an attachment to this response to comments document to clarify the Administrative Record.

Comment 4 On page 11 of 16, paragraph 1, line 5, there is a typographical error relative to the allowable AT limit at the edge of the HDA during the non-summer period.

Applicable regulations establish a AT of 4.0 OF as the standard during the non-summer period. The Statement of Basis presently

Response to Comments Page 3 of 5 Permit No. NJ0025411 states "Since compliance with the 40 °F limit at the edge of the HDA was predicted when ATHCcT equals 46.2 °F...."

Response 4 The Department acknowledges this typographical error and hereby incorporates this information into the Administrative Record. This statement should read "Since compliance with the 4°F limit at the edge of the HDA was predicted when ATHCCT equals 46.2 OF,..."

Permit Summary Table Comment 5 PSEG believes that the note on the Permit Summary Table, which appears at page 15 of 16, lines I through 3, should contain language consistent with the intent indicated at page 11 of 16, discussed above in Comment 1.

The note presently states:

Given a coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period of greater that 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

PSEG believes that this note should read, as follows:

Given a coincident occurrence of wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period equal to or [o*]

greater than 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

Response 5 As discussed in Response 1, the Department agrees that its intent was for this temperature reporting requirement to apply given a coincident occurrence of wet bulb temperature that exceeds 76 degrees Fahrenheit and a relative humidity below 60% for a period equal to or greater than 60 minutes during a given day. The correct language has been included in Part III B/C of this final permit modification. This clarification is hereby incorporated into the Administrative Record.

Comment 6 The first note on the Permit Summary Table, which appears at page 15 of 16, lines 3 through 6, proposes to require that PSEG measure a number of identified parameters, including AT in

Response to Comments Page 4 of 5 Permit No. NJ0025411 degrees Fahrenheit, heat in MBTU/Hr, wet bulb Temperature and relative humidity. As indicated in the proposed modification to the permit for DSN 461A and footnote 7 to the proposed permit modification itself, the parameters listed herein can not be measured but must be calculated; therefore, the sentence should be amended. Proposed language is as follows:

If these two conditions for wet bulb temperature and relative humidity are met, the permittee is required to measure or calculate, as appropriate the following parameters at the Station,...

Response 6 The Department hereby incorporates this information into the Administrative Record. Because the correct language was included in Part III-B/C in footnote 7, no change is necessary to Part III-B/C of this final permit modification.

Part III - B/C Comment 7 Footnote 7, lines 1 through 3 to the effluent limitations for DSN 461A (page 2 of 8) presently states:

Given a coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period of greater that 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

PSEG believes that footnote 7, lines I through 3 should read, as follows:

Given coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period equal to or [of] greater than 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

Response 7 As discussed in Response 1, the Department agrees with this clarification and has incorporated this change in the final permit modification on this same page.

Comment 8 Paragraph 2 of Footnote 7 indicates that the monitoring for certain of the parameters identified in paragraph 1 are monitored at 15 minute intervals at Hope Creek's Meteorological Station. This is an accurate statement. However, it could be construed as a requirement that all data used for NJPDES compliance for these parameters have been collected at this location. While PSEG

Response to Comments Page 5 of 5 Permit No. NJ002541 I full' intends to continue collecting meteorological data at this Station and to maintain and operate the instrumentation properly at all times, PSEG respectfully requests that the NJDEP include the following sentence at the end of paragraph 2 to Footnote 7:

In the event that data are not available from the Hope Creek Meteorological Tower, then PSEG may utilize data collected at the Wilmington Meteorological Station ("Wilmington"), so long as the use of Wilmington data or other alternative source, if approved in advance by the NJDEP, is duly noted on the DMR and the permittee retains records of the Wilmington data or any other data in its DMR back up file for the term specified by applicable provisions of the NJPDES regulations.

Response 8 The Department supports this clarification and has included a slightly modified version of the proposed language in Footnote 7 of Part III-B/C as part of this final permit modification.

Part IV-B/C Comment 9 Section M, entitled "Compliance with DRBC Docket D-73-193 CP (Revised April 25, 1984)"

requires that PSEG ensure compliance with all DRBC Docket requirements, including the maximum temperature standard of 86'F. PSEG has in numerous filings with the NJDEP for both Hope Creek and its adjacent Salem Generating Station presented data and information demonstrating that the temperature in the Delaware can reach or exceed 86°F due to natural circumstances. On such days, PSEG is unable to achieve compliance with this requirement.

PSEG has demonstrated that the combined effects of its thermal discharges from Salem and Hope Creek together with warmer ambient temperatures does not threaten the protection and propagation of the balanced indigenous population of fish, shellfish and wildlife in or on the receiving water.

PSEG, therefore, respectfully requests that the NJDEP clarify in the response to comments that this reference to Hope Creek's DRBC docket does not require compliance with the 86'F requirement, based on a successful demonstration consistent with §316(a) of the Clean Water Act.

Response 9 Based on Comment 9, the Department has reworded this section in Part IV-B/C to explain that PSEG shall ensure compliance with all DRBC Docket requirements, but has not specifically stated that PSEG is required to comply with the 86°F requirement. This serves to address the concern raised in Comment 9.

Hope Creek Generating Station NJPDES Permit No. NJ0025411 Draft Permit Modification i

Dear Mrs. Hammond:

By this letter, Public Service Nuclear, LLC ("PSEG" or the "Company") is submitting its comments on the Fact Sheet, Statement of Basis and Draft Permit Modification (collectively, the "Draft Permit") to the New Jersey Pollutant Discharge Elimination System ("NJPDES") for Hope Creek Generating Station ("Hope Creek").

The New Jersey Department of Environmental Protection issued the Draft Permit to PSEG on August 17, 2000 and requested comments within thirty days; therefore, these comments are timely filed, consistent both with applicable regulations and the Public Notice accompanying the Draft Permit.

PSEG supports the NJDEP's proposal to modify the temperature limit for cooling tower blowdown established in Hope Creek's existing NJPDES permit. The attached comments are, accordingly, primarily technical corrections or requests for clarification.

If you or your staff have any questions, please do not hesitate to contact Thomas J. Harlukowicz, Ph.D. at (973) 430-8423, James M. Eggers at (856) 339-7900 or me.

Very truly yours, AMaureen F. Vaskis Attach. (1)

S. T. Rosenwinkel (w/attach.)

PSEG's Conuments on the Fact Sheet, Statement of Basis and Draft Permit Modification Hope Creek Generating Station New Jersey Pollutant Discharge Elimination System Permit Public Service Nuclear LLC.'s ("PSEG" or the "Company") provides the following comments on the Fact Sheet, Statement of Basis, and Draft Permit Modification (collectively, the "Draft Permit Documents") for Hope Creek Generating Station's ("Hope Creek") New Jersey Pollutant Discharge Elimination System

("NJPDES") permit. The comments are organized by document, component and paragraph. For example, all comments on the Fact Sheet are presented first in Section I of the document. Within this section, the comments are then arranged by major components and finally by paragraph. In many instances, PSEG both raises a comment and proposes alternate language for the NJDEP's consideration. If PSEG proposes additional language it is set forth in bold and underscored. If PSEG proposed deleting certain words or phrases in a given sentence, the words or phrases are shown in brackets and are struck out.

I.

Comments on Fact Sheet A.

Given slight differences in language in the Draft Permit Documents, the specific requirements relative to when the stay is applicable are ambiguous. PSEG requests that the language proposed below, which is consistent with PSEG's understanding of the intent of the proposed modification, given the statement at page 11 of 16 in the Statement of Basis section entitled, "Modification to Effluent Limitation for DSN 461A. PSEG respectfully requests that the language PSEG proposes below be used in the final permit modification and that the NJDEP clarify through its response to comments that the language in the Draft Permit Documents should be interpreted consistently with the language at page 11 of 16 and said language in the final permit modification.

At Section III, paragraph 1, line 7, the Fact Sheet provides that These conditions for the average wet bulb temperature and the relative humidity must occur concurrently for a time period of greater than 60 minutes for this temperature reporting requirement to apply.

PSEG proposes that this sentence read as follows:

These conditions for the average wet bulb temperature and the relative humidity must occur concurrently for a time period [e4i equal to or greater than 60 minutes for this temperature reporting requirement to apply.

II.

Comments on Statement of Basis A.

In the section heading on page 4 of 16, the dates shown in the section heading do not agree with the dates in the body of the text, which are the correct dates.

The section heading presently states:

Background for Hope Creek's Cooling Tower Design Based on PSE&G's 11/15/99 & 6/2/200 Submittals The section heading should read as follows:

Background for Hope Creek's Cooling Tower Design Based on PSE&G's 11/[4--117/99 & 6/2/2000 Submittals B.

On page 10 of 16, paragraph 3, line there is a reference to Table I.A-I. PSEG notes that none of tables included in the Draft Permit Documents are identified as such.

PSEG questions if this is a reference to Table 1 on page 7 or to another table.

C.

On page 11 of 16, paragraph 1. line 5, there is a typographical error relative to the allowable A T limit at the edge of the HDA during the non-summer period. Applicable regulations establish a AT of 4.0 ° F as the standard during the non-summer period.

The Statement of Basis presently states:

Since compliance with the 400 F limit at the edge of the HDA was predicted when ATHCcT equals 46.2' F,...

D.

PSEG believes that the note on the Permit Summary Table, which appears at page 15 of 16 lines 1 through 3, should contain language consistent with the intent indicated at page 11 of 16, discussed above.

The note presently states:

Given a coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period of greater that 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

PSEG believes that this note should read, as follows:

Given a coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period equal to or [eo9 greater than 60 minutes 2

during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

E.

The note on the Permit Summary Table, which appears at page 15 of 16, lines 3 through 6, proposes to require that PSEG measure a number of identified parameters, including AT in degrees Fahrenheit, heat in MBTU/Hr wet bulb Temperature and relative humidity. As indicated in the proposed modification to the permit for DSN 461A and footnote 7 to the proposed permit modification itself, the parameters listed herein can not be measured but must be calculated using the certain of the other parameters included in the list, the sentence should be amended.

The first note to the Permit Summary Table at page 15 of 16, lines 3 through 6, presently states:

If these two conditions for wet bulb temperature and relative humidity are met, the permittee is required to measure the following parameters at the Station,...

This sentence should read as follows If these two conditions for wet bulb temperature and relative humidity are met, the permittee is required to measure or calculate, as appropriate, the following parameters at the Station,...

Part III - B/C Permit No. NJ002541 1, A.

Page 2 of 8 Pages, Modified:, Footnote 7, lines I through 3 to the effluent limitations for DSN 461A presently states:

Given a coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period of greater that 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

PSEG believes that footnote 7 lines I through 3 should read, as follows:

Given a coincident occurrence of a wet bulb temperature that exceed 76 degrees Fahrenheit and a relative humidity below 60% for a period equal to or [efj greater than 60 minutes during a given day, the daily maximum temperature limit does not apply and monitoring only is required.

B.

Paragraph 2 of Footnote 7 indicates that the monitoring for certain of the parameters identified in paragraph 1 are monitored at 15 minute intervals at Hope Creek's Meteorological Station. This is an accurate statement. However, it could be construed as 3

a requirement that all data used for NJPDES compliance for these parameters have been collected at this location. While PSEG fully intends to continue collecting meteorological data at this Station and to maintain and operate the instrumentation properly at all times, PSEG respectfully requests that the NJDEP include the following sentence at the end of paragraph 2 to Footnote 7:

In the event that data are not available from the Hope Creek Meteorological Tower, then PSEG may utilize data collected at the Wilmington Meteorological Station ("Wilmington"), so long as the use of Wilmington data or other alternative source, if approved in advance by the NJDEP, is duly noted on the DMR and the permittee retains records of the Wilmington data or any other data in its DMR back up file for the term specified by applicable provisions of the NJPDES regulations.

C.

Section M. Compliance with DRBC Docket D-73-193 CP (Revised April 25, 1984) requires that PSEG ensure compliance with all DRBC Docket requirements AT temperature applicable at the edge of the HAD, including the maximum temperature standard of 860 F. PSEG has in numerous filings with the NJDEP for both Hope Creek and its adjacent Salem Generating Station presented data and information demonstrating that the temperature in the Delaware can reach or exceed 86' F due to natural circumstances. On such days, PSEG is unable to achieve compliance with this requirement. PSEG has demonstrated that the combined effects of its thermal discharges from Salem and Hope Creek together with warmer ambient temperatures does not threaten the protection and propagation of the balanced indigenous population of fish, shellfish and wildlife in or on the receiving water. PSEG, therefore, respectfully requests that the NJDEP clarify in the response to comments that this reference to Hope Creek's DRBC does not require compliance with the 860 F requirement, based on a successful demonstration consistent with §316(a) of the Clean Water Act.

(7)

Given a coincident occurrence of a wet bulb temperature that exceeds 760 F and a relative humidity below 60 percent during a given day for a period equal to or greater than 60 minutes, the daily maximum temperature limit does not apply and monitoring only is required. If these two conditions for wet bulb temperature and relative humidity occur, the permittee is required to submit a chart with columns for the following data for each hour of that day: (1) Cooling Tower Blowdown flow (gpm); (2) Intake Temp (OF); (3) Blowdown Temp (OF); (4) AT (OF);

(5) MBTU/Hour; (6) Dry Bulb Temp (OF); (7) Dew Point Temp (OF); (8) Wet Bulb Temp (OF); and (9) Relative Humidity (%).

Dry bulb temperature, dew point, barometric pressure and wind speed and direction are measured at 15 minute intervals at Hope Creek's Meteorological Station.

Wet bulb temperature and relative humidity are computed using measurements of dry bulb temperature and dew point with a numerical algorithm that relates the dependence of wet bulb temperature and relative humidity on dew point, dry bulb temperature, and atmospheric pressure. In the event that data are not available from the Hope Creek Meteorological Tower, then PSEG may utilize data collected at the Wilmington Meteorological Station

("Wilmington").

The use of Wilmington data or another alternative source must be approved in advance by the NJDEP and duly noted on the DMR. The permittee must retain records of the Wilmington data or any other data in its DMR back up file for the term specified by applicable provisions of the NJPDES regulations.

Hope Creek Generating Station NJPDES Permit No. NJ00025411 Request for Permit Modification (N.J.AKC. 7:14A-16.4) and Interim Stay of Permit Limitation (N.J.A.C. 7:14A-17.6)

Dear Mr. Hart:

As you are aware, the New Jersey Pollutant Discharge Elimination System ("NJPDES")

Permit for Public Service Electric and Gas Company's ("PSEAG" or the "Company") Hope Creek Generating Station ("Hope Creek" or the "Station") establishes technology-based effluent limitations for pollutants in a mimber of effluu streams miud temperature for the cooling tower blowdwn effluent sum Hope Creek is a base-load audear power plant that operates with a closed cycle cooling water system ("CWS"). The Hope Creek CWS relies on a natural draft cooling tower to cool the cculatin water through evaporation.

As you are further aware, on or about July 9, 1999, PSE&G asserted an affirmative defense in connection with a July 5, 1999 exceedance of the aunum, daily tmperature limitation applicable to this effluent stream. Since filing that affirmatve defenme, PSE&G has collected and Amtrh analyzed Station operating data and mteolo data collectd in July 1999 and has developed a more refi under di of the meteoro.ogical crumstances which resulted in the exceedance. PsE&G is, hereby, seeking a modification ofHope Creek's NJPDES Permit to incrse the modmin daily avma temperature limitation to accommodate thd degree of cooling achievable with the existing cooling tower technology pursuMant to N.J.A.C. 7:14A 16.4(b)15. In this regard, the information required under the applicable subsections of N.J.A.C.

7:14A-16.3 and 16.4 is addressed in Section I, below. In addition, PSE&G is seeking an interim 0

.S

.I..

Mr. Dennis Hart November 17, 1999 Page 2 stay of this limit, under the conditions identified below, pending the NJDEP's action on PSE&G's request for a permit modification, pursuant to NJ. A.C 7-.14A-17.6(a) 2. The information to support this request is provided in Section II, below. Finally, in accordance with N.J.A.C. 7 14A 13.19,Section III of this letter sets forth the bases for determining that this request for a permit modification, which if granted would incorporate a less stringent effluent limitation, is in compliance with the applicable requirements of section 402(o) of the Federal Clean Water Act, 33 U.S.C. §1342.

I.

Request for Permit Modification Pursuant to N.J.A.C. 7:14A-16.3 and 16.4.

This section of this request for a permit modification addresses both the procedural requirements of subsection 16.3(b) and the substantive requirements of subsection 16.4(b) 15, For ease in determining the administrative completeness of this request, each subsection and its requirement are set forth below. Supporting information is set forth in attachments ILA to I.C to this letter.

A.

§§16.3(b) 1 and 2. Request Must Be in Writing.

By virtue of this letter request and supporting documentation, these requirements are satisfied.

B.

§§16.3(b) 3. Identification of Potentially Affected Environmental, Aesthetic or Recreational Interests.

By virtue of the nature of this request for permit modification, as discussed more fully below, there will be no environmental, aesthetic or recreational interests that will be affected by a relatively slight increase in the temperature of the cooling tower blowdown.

The increase in effluent limitations is required for those times when, due to meteorological conditions, the cooling tower can not achieve the existing limits. Moreover, the discharge, even at the higher limits requested, will achieve compliance with the differential temperature (AT) standard for mixing zones established by the Delaware River Basin Commission ("DRBC") in its Docket for the Station for this effluent stream. This mixing zone is more stringent than the guideline, which is set forth in the NYDEP's and DRBC's regulations, designed to ensure protection of the designated uses of the Delaware River in the vicinity of the discharge. These uses address the environmental, aesthetic, and recreational interests of the Delaware. Attachment I.A. presents information in support of PSE&G's assertion that the increase in the limitations will not exceed the maximum allowable AT at the edge of the mixing zone for heat and temperature for the cooling tower blowdown discharge.

C.

§16.3(b) 4. Compliance with Outstanding Fee, Penalty or Fine Requirement As of the time of filing this request, PSE&G has not been issued any fine or penalty in connection with the single exceedance of the existing effluent limitation for which a less

Mr Dennis Hart November 17, 1999 Page 3 stringent limitation is being sought. There are no other outstanding fees, penalties or fines pending against Hope Creek. Attachment I.B. is a copy of PSE&G's July 9, 1999 letter to NJDEP, asserting an affirmative defense for the July 5, 1999 exceedance.

D

§16.3(b) 5i. Updated Permit Application, pursuant to N.J.A.C. 7.14A-4 2.

This section requires that a request for permit modification include an updatzd application consistent with N.J.A.C. 7:14A-4.2 This section does not provide any specific direction with respect to the filing of an application for a permit modification. At a pre-application conference, the NJDEP advised that in this instance an updated application form would not be required, and that this letter request would constitute the application. If, during the course of reviewing this letter request, the NJDEP determines that additional aspects of the application must be updated, PSE&G will gladly comply with the request.

E.

§16.4(b) 15. Technology Required Per the Permit Has Been Installed and the Applicable Effluent Limitation Are Not Achievable Under All Conditions.

Hope Creek is a base-load, nuclear-powered generating station, which was designed and constructed to operate with a closed cycle cooling water system with a natural draft cooling tower. Cooling towers are designed for typical, regional meteorological conditions. Conditions beyond these design parameters reduce the ability of a natural draft towers to perform. The design parameters of Hope Creek's natural draft cooling tower were established, assuming typical meteorological conditions for the Delaware River region. The cooling tower was constructed consistent with these design parameters, which were (along with the effluent limitations that such a tower could achieve) identified in PSE&G's initial Treatment Works Approval ("TWA") and NJPDES applications. The design parameters are:

Duty: 7.972 X 109BTU/hr Inlet Water Flow: 552,000 gpm Inlet Water Temperature (Thj,,): 119 OF Outlet Water Temperature (Tow.,): 90 OF Ambient Wet Bulb Temperature: 76 OF Relative humidity: 60%

Range (T,

- T..ti.t): 29 OF Approach ( Tw,, - Wet Bulb): 14 OF The NJDEP considered this information in connection with its development and issuance of the effluent limitations for cooling tower blowdown temperature in Station's initial and subsequent NJPDES permits.

PSE&G has also properly operated and maintained the relevant facilities, including the cooling tower. Attachment I. C. hereto is the affidavit of the Vice President - Operations

MýAr. Dennis Hart November 17, 1999 Page 4 of the NBU in support of this assertion. Natural draft cooling towers are essentially static devices, which rely upon the design of the tower and the operations of the laws of thermodynamics to accomplish the cooling of the condenser water. The hot water from the condensers is pumped about a quarter of the way up the tower through piping to spray nozzles which distribute the water over the cement fill sheets. The air is warmed by the water, which causes the air to become less dense and rise up through the tower. As the wet air rises, the water droplets are removed by the drift eliminators, which are above the spray nozzles. The three major factors in the heat transfer of the tower are: the inlet water to air (wet bulb) temperature difference; the airflow through the tower, and the water distribution in the tower. The cooling tower consists of the outer structure, the hyperbolic tower itself, plus its internal components, the water distribution system (comprised of pipes, valves and spray nozzles), the fill sheets and the drift eliminators. Other than the repair and/or maintenance of these internal components, there are no operational controls associated with the cooling process using a natural draft cooling tower.

The internal components of the cooling tower may undergo some degradation during a normal operating cycle. PSE&G has developed and implemented an appropriate maintenance program, consistent with industry practice, for the cooling tower. This program includes: inspecting the internal components of the cooling tower during each refueling outage; cleaning the tower; removing silt from basin and pipes; cleaning drift eliminators; and repairing and/or replacing the components, as necessary.

H.

Stay of Effluent Limitations Pursuant to N.J.A.C. 7:14A-17.6.

In that PSE&G is requesting a stay of the existing permit limitation pursuant to subsection (a) 2, relating to modifications of existing permits, N.J.A.C. 7:14A-17.6 does not specifically require that PSE&G submit any additional information to support this request. However, during a pre-application conference, the NJDEP specifically requested that PSE&G provide information to the NJDEP addressing certain of the items identified in subsection (c) of the above-referenced section.

A. Ability to Comply with the Existing Limits Pursuant to §17.6(c)1.

As PSE&G Discharge Monitoring Report ("DMR") data demonstrate, Hope Creek has only experienced a single exceedance of the current temperature limit. It is important to note that this exceedance resulted in a maximum daily temperature that was less than one degree in excess of the current limitation. As the analysis included here as Attachment II. A. Indicates this exceedance was due to the combined occurrence of certain meteorological conditions, i.e., low relative humidity and high wet bulb temperature. As these conditions are outside of the design parameters for Hope Creek's tower, it is increasingly more difficult to achieve the level of cooling that would allow compliance under these conditions.

Mr Dennis Hart November 17, 1999 Page 5 B. Ability to Comply by Implementing Low Cost Short Term Modifications to the Treatment Technology Pursuant to § 176(c) 2.

As discussed above in I F, natural draft cooling towers are relatively static devices. There are no low cost, short-term modifications to the cooling tower or to the cooling system that could be implemented that would allow Hope Creek to achieve compliance with this limitation. In particular, there are no treatment process modifications, chemical additions, pollution abatement/prevention or change in the products generated that could be implemented that would result in compliance with the existing limit. Moreover, reductions in the output of the Station would not result in compliance with the temperature limit under the conditions that cause the non-compliance, as demonstrated in Attachment II.B As discussed during the pre-application conference, PSE&G is, however, undertaking a diagnostic study to determine whether modifications to the water flow patterns within the cooling tower would increase its cooling capacity. This diagnostic study was conducted in October; the results be used to assess whether more time-intensive and extensive studies are warranted. PSE&G will provide the NJDEP with the results of the diagnostic study when the review and analysis of the data are complete.

C. Level of Control Achievable and Cost of Short Term Modifications Pursuant to Subsections (c) 3 and 4.

These sections are not applicable, since no applicable, short term modifications were identified.

D. Environmental Impacts Pursuant to Subsection (c)5.

As discussed in Section I.B above, the increase in the temperature limit will not cause the cooling tower blowdown to exceed the maximum allowable AT at the edge of the mixing zone established by the DRBC and the NJDEP. Moreover, PSE&G has recently conducted exhaustive studies on the effects of heat and temperature of the natural resources of the River including its biota. These studies demonstrate that temperatures in the range of cooling tower blowdown discharge do not have any adverse effect on the natural resources or environment of the Estuary.

II.

Compliance with the Anti-Backsliding Pursuant to N.J.A.C. 7:14A-13.19 and 33 USC §1342(o).

The federal CWA includes a prohibition against the imposition of less stringent effluent limitations in permit modifications or renewals unless a permittee can make the requisite proofs to overcome the prohibition. Consistent with federal law, N.J.A.C. 7: 14A-13.19 prohibits the imposition of less stringent effluent limitations through a permit modification unless the requirements of section 402(o) have been addressed. PSE&G's request for less stringent effluent limitation on temperature satisfies all of those requirements.

Mr Dennis Hart November 17, 1999 Page 6 A.

Exceptions Identified at Subsections (2) (C) Relative to Conditions beyond the Permittee's Control and (2) (E) Relative to Installation, Operation and Maintenance of the Permit-Required Treatment Technology Are Applicable.

As discussed in Section I. B and I.F, above, the exceedance of the temperature limit for the cooling tower blowdown is caused by the coincident occurrence of certain meteorological conditions (i.e., high wet bulb temperature and low relative humidity), which are beyond PSE&G's control. In addition and as discussed in Section I.F above, PSE&G has installed the treatment technology required under the Station's NJPDES permit and has properly operated and maintained this equipment. Therefore, PSE&G has presented information with this application demonstrating it has satisfied the requirements of section 402(o)(2)

B.

There Is No Applicable Effluent Limitation.

Subsection 402(o)(3) provides that less stringent limitations shall not be imposed if an effluent limitation guideline is in place at the time the request is filed. USEPA has not re promulgated effluent limitation guidelines applicable to heat and temperature since the initial guidelines were overthrown by the court in Appalachian Power et al. v. Train in 1976.

C.

The Imposition of Less Stringent Limitations Will Not Cause an Exceedance of Applicable Water Quality Standards.

As indicated in Section I.B above and as is demonstrated by the materials included in Attachment A., the NJDEP's issuing a permit modification to increase the maximum temperature limitation for the cooling tower blowdown will not cause the thermal discharge to exceed the maximum allowable AT at the edge of the mixing zone established by the DRBC or the surface water quality standards for heat and temperature established by the DRBC and adopted by the NJDEP.

IV.

Conclusion.

PSE&G has, by this letter, satisfied all of the applicable requirements for requesting a modification of Hope Creek's NJPDES Permit and for an interim stay of said limits, pending the NJDEP's action on the request for permit modification. The combination of high wet bulb temperature and low relative humidity puts the Hope Creek cooling tower in a condition that decreases the overall heat transfer capability of the tower and results in higher blowdown temperatures. If wet bulb temperatures are persistently beyond the design specification for the tower (76°F), the potential for exceeding the blowdown temperature limit increases. This risk for exceeding the limit is increased substantially if the relative humidity drops below the tower design specification (60 percent) at the same time the wet bulb temperature is beyond its design specification. Therefore, PSE&G is requesting that the NJDEP stay the existing limit anytime when: (1) both the wet bulb temperature and relative humidity are outside of their respective

Mr Dennis Hart November 17, 1999 Page 7 design specifications concurrently; or (2) the wet bulb temperature on a given day is exceeded eight (8) hours or more. The analysis of the relevant meteorological data that formed the basis for this proposed conditions is included in Attachment II.A If you or your staff have any questions or require any additional information, please do not hesitate to contact Thomas J. Harlukowicz, Ph.D. at (973) 430-8423, James M Eggers at (856) 339-1339 or me.

Attachment L.A Compliance with Maximum Allowable Temperature Increase at the Edge of the Heat Dissipation Area for Hope Creek Generating Station The Delaware River Basin Commission (DRBC) established a Heat Dissipation Area (HDA) for Hope Creek Generating Station (the Station) that extends 2,000 up-estuary, 2,000 ft down-estuary, and 1000 ft offshore from the point of discharge. The daily average temperature increase (AT) at the edge of the HDA is limited to 1.50F during the summer period (June through August) and 4.0°F during the non-summer period (September through May). The actual daily average temperature increase at the edge of the HDA (AT) depends on the difference between the daily averages of blowdown temperature and intake water temperature (namely, ATHccT = Tblowdown - Tintake), and the dilution of the blowdown due to tidal mixing.

The current thermal effluent limits for the cooling tower blowdown effluent were based on a hydrothermal study of the blowdown from Hope Creek Cooling Tower (HCCT). The study was performed by J. E. Edinger Associates Inc. (Edinger) in 1994 and included calculations of daily averages of Tbiowdown, heat rejection rates, and ATHCCT. The calculations were made using observed meteorological conditions and three power levels (namely, 100%, 79% and 50%) for each day of a 46 year period (1948 to 1993). The maximum calculated daily average of ATHCCT was 28.40F for the summer period and 46.20F for the non-summer period.

Using a minimum measured dilution of 20 from a dye study of the HCCT blowdown (LMS, 1991), the maximum expected value of AT was estimated as 1.40F (namely, 24.80F/20) for the summer period, and 2.30F (namely 46.20F/20) for the non-summer period. Thus, compliance with the maximum allowable temperature increase at the edge of the HDA was predicted.

If adverse meteorological conditions cause the daily average blowdown te'mperatures to exceed the current discharge limit for temperature (97.1 IF), the

resulting temperature increase at edge of the HDA is not expected to exceed 1.50F during the summer period or 4.00 F during the non-summer period. The calculated relationship between ATHCCT and Tblowdown based on Edigner's hydrothermal study shows ATHCCT tends to be a maximum at blowdown temperatures that are 5°F to 1 0°F below the current permit limit. Figures I.A - 1, L.A - 2, and I.A - 3 show the relationships for the summer and non-summer periods when the Station is operating at 100%, 79% and 50% power, respectively.

For the summer period, the overall maximum value of ATHCCT (28.40 F) for the 46 year period is predicted to occur when the daily average discharge temperature is approximately 90.0°F. The maximum value of AT over the ranges of variation at higher discharge temperatures decreases as Tbiodow, approaches the current permit limit (97.1 OF). When Tblowdown equals 97.1 OF, the maximum predicted daily average AT is approximately 19.0°F. These results are consistent with actual measurements of ATHCCT for July 1999 (Table L.A - 1). The maximum measured daily average value of ATHCCT was 14.50F on July 5, 1999 when the daily average value of Tblowdown equaled 98.0°F; and the daily maximum hourly daily AT's was 17.8 0F on July 4, 1999 when the daily average value of TbIowdown equaled 96.0°F.

Both measurements of ATHCCT are well below the value of AT (28.40F) that was used to assess compliance with the allowable AT at the edge of the HDA for the summer period.

The calculations performed by Edinger and actual measurements of ATHCCT during July 1999 indicate that the daily average AT will not exceed 28.40F, and is more likely to be less than 200F. There is no evidence in Figure l.A-1 through I.A-3 to show that ATHCCT would increase significantly above 20°F (or at all) for Tblodown in modest excess of 97.10F. Since compliance with the 1.50F AT limit at the edge of the HDA was predicted when ATHccT equals 28.40F, compliance is also expected during the summer period when adverse meteorological conditions

cause Tblowdown to exceed the current permit limit 97. 1OF by several degrees Fahrenheit.

For the non-summer period, the maximum value of ATHCCT (46.20F) is predicted to occur at a daily average discharge temperature of approximately 86.03F The maximum value of AT over the ranges of variation at higher discharge temperatures decreases as TbIowdown approaches the current permit limit (97.1 OF).

At the calculated maximum daily average value of Tbiowd*own for the non-summer period, ATHCCT is approximately 15.00 F. There is no evidence in Figure I.A-1 through LA-3 to show that the maximum value of ATHCCT will increase significantly above 150F (or at all) if TbIowdown were to exceed 97.1 OF by several degrees Fahrenheit. Since compliance with the 4.0°F limit at the edge of the HDA was predicted when ATHCCT equals 46.20F, compliance is also expected during the non-summer period should adverse meteorological conditions cause Tblowdown to exceed the current permit limit 97. 1OF by several degrees Fahrenheit.

Dear Sir:

PUBLIC SERVICE ELECTRIC & GAS COMPANY HOPE CREEK GENERATING STATION NJPDES PERMIT NO. NJ0025411 REPORT OF UPSET CONDITIONS AND AFFIRMATIVE DEFENSE PURSUANT TO N.J.A.C. 7:14A - 6.10 and 6.11 In support of its assertion of an affirmative defense pursuant to N.J.A.C. 7:14A - 6.11 and the upset report pursuant to N.J.A.C. 7:14A - 6.10, Public Service Electric and Gas Company (PSE&G) has prepared this letter report. The daily average of the hourly temperatures recorded at the monitoring location for Discharge Serial Number (DSN) 461A was 98.00 F for July 5, 1999. At the time PSE&G notified the NJDEP Hotline of the upset condition on Tuesday, July 6, 1999 (N.J.D.E.P Hotline Report # 99-07-06 1142-37), PSE&G did not have available final calculations of the daily average temperature and reported the maximum daily average as 97.80 F.

The upset condition was due to extreme meteorological conditions, which resulted in an exceedance of the daily average maximum temperature limit applicable to the cooling tower blowdown effluent The cooling tower, which is the control technology for effluent temperature, was properly maintained and all systems related to the thermal discharge were properly operated at the time of the incident.

The fpllowing information is submitted in accordance with N.J.A.C. 7:14A - 6.10 (e):

The pcuer is *in you-r [nds.

95-Z6d A~v 619

DESCRIPTION OF THE DISCHARGE.

Time of discharge - 7/5/99 Volume of discharge - 38,000 gpm Concentration of pollutant discharged - N/A Receiving water - Delaware River

2.

STEPS BEING TAKEN TO DETERMINE CAUSE OF EXCEEDANCE.

Based on reviews of the Station's NJPDES monitoring data and meteorological data collected at Wilmington, Delaware, meteorological conditions caused this upset. A comparison of the meteorological data from the days immediately proceeding and following July 5, 1997 support this conclusion.

3.

STEPS BEING TAKEN TO REDUCE, REMEDIATE, AND ELIMINATE THE NONCOMPLYING DISCHARGE AND ANY DAMAGE TO THE ENVIRONMENT.

Given that the exceedance was due to unusual meteorological conditions, the cause of the exceedance was abated when the conditions changed. The Station is presently in compliance with the temperature limit. There have neither been indications of adverse effects to the environment associated with this discharge, nor reason to believe, based on recent studies and evaluations of the effects of thermal discharges on the Delaware River, that any damage to the environment occurred.

4.

THE DURATION OF THE DISCHARGE.

This is a 24-hour average limit; this report relative to the upset is for calendar day July 5.

5.

CAUSE OF THE NONCOMPLIANCE.

As noted in 2 above, the cause was the unusual meteorological conditions.

6.

STEPS BEING TAKEN TO REDUCE, ELIMINATE OR PREVENT THE REOCCURRENCE.

Although the cause of the exceedance was the extreme meteorological conditions that occurred on the day in question, the Station is also reviewing whether there are modifications to the cooling tower design that would improve its efficiency. The investigation will also determine if additional actions are warranted to correct the cause of the discharge.

7.

ESTIMATE OF THE THREAT TO HUMAN HEALTH OR THE ENVIRONMENT.

There are neither any indications of, nor any basis to believe that, any threat to the human health or the environment occurred as a result of this exceedance.

a.

MEASURES THE PERMITTEE IS TAKING TO REMEDIATE THE PROBLEMIDAMAGEIINJURY TO HUMAN HEALTH OR THE ENVIRONMENT.

As noted in number 3 above, the cause of this exceedance was the unusual meteorological conditions. As noted above, the Station is researching whether modifications to the tower will improve efficiency. As noted above, there were no damages or injuries to human health or the environment.

The following information is submitted in accordance with N.J.A.C. 7:14A - 6.10(f) 4.i and ill as Attachments 1 and 2, respectively: Operating Logs for July 5, 1995 and Station Monitoring and meteorological data.

Any questions regarding this report may be referred to Susan Miller at (609) 339 2649.

Sincerely, D.R. Powell Director-Ucensing/Regulation & Fuels

AFFIDAVIT OF MARK B. BEZILLA I, Mark B. Bezilla, being of full age and first duly sworn say as follows.

1.

I am the Vice President - Operations of Public Service Electric & Gas Company's

("PSE&G") Nuclear Business Unit ("NBLU'), and am fully familiar with the facts set forth herein.

2.

As Vice President - Operations, I have overall responsibility for the operations and maintenance of Salem and Hope Creek Generating Stations.

3.

1 have a Bachelor of Science Degree in Nuclear Engineering Technology and have been employed in the nuclear power industry since 1976.

4.

Prior to joining PSE&G, I was employed by three other electric utility companies, working at nuclear generating stations that have closed-cycle circulating water systems which operate with natural draft cooling towers.

5.

I have been employed at PSE&G since June 1996. Prior to my current position I served as General Manager - Hope Creek Operations from June 1996 to July 1999. As such, I had overall responsibility for the operations and maintenance of all systems at Hope Creek including the circulating water system.

6.

I am familiar both with PSE&G's maintenance program for the Hope Creek circulating water system and cooling tower. PSE&G's present maintenance program for Hope Creek's circulating water system and cooling tower includes: inspections of the cooling tower internal components; removal of silt from the basin and associated piping; cleaning the drift eliminators; and making necessary repairs to components. This program is implemented during each refueling outage.

7.

The maintenance program at Hope Creek is generally consistent with the circulating water system and cooling tower maintenance programs at the other generating stations where I have worked.

8.

These practices are consistent with sound engineering practices and are generally the same as those practices applied at the other facilities at which I have worked and with the industry's practices.

Sworn to before me this day of7i c, 1999

Attachment II.A Analysis of Meteorological Conditions and Blowdown Temperatures for July 1999 Hope Creek Cooling Tower was designed for a wet bulb temperature of 76 0F or lower, and a relative humidity of 60% or higher. Meteorological conditions that occurred during July 1999 frequently were outside the design conditions and caused unexpectedly high blowdown temperatures that caused the temperature of the cooling tower blowdown effluent to approach, and on one occasion exceed, the current permit limit of 97.1 OF for the maximum daily average discharge temperature.

On July 4, 1999, the wet bulb temperature remained above 760F most of the day, and the relative humidity dropped below 60% for several hours in the afternoon.

As a consequence, the blowdown temperature approached, but did not exceed, the current permit limit for temperature. On July 5, 1999, the wet bulb temperature remained above 76 0 F during the entire day, and the relative humidity dropped below 60% for approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br />. As a result, hourly blowdown temperatures often exceeded the permitted daily average blowdown temperature (97.1 OF) by 1 to 20F. The actual daily average blowdown temperature for July 5, 1999 was 98.0°F.

An analysis of the Station's meteorological data and blowdown temperature records was performed to better understand the potential effect of adverse meteorological conditions (namely wet bulb temperatures in excess of 76°F and relative humidity less than 60%) on blowdown temperature. Table II.A - 1 summarizes the meteorological data and effluent temperature data for July 1999 and also includes data for August 1, 1999 when the potential for a similar episode developed. The table provides the number of hours each day that: (1) the wet bulb temperature exceeded 76 0F but the relative humidity remained at or aabove 60%; (2) the wet bulb temperature was less than 76°F but the relative

humidity fell below 60%, and (3) the number of hours that the wet bulb temperature exceeded 760F and the relative humidity fell below 60%. A compilation of the daily averages of the blowdown temperature, wet bulb temperature, relative humidity, and temperature increase across the cooling tower is provided in the middle of the table. The three rightmost column of the table list the maximum hourly values of temperature increase across the cooling tower and the discharge temperature, and the number of hours that the hourly discharge temperature exceeded the current permit limit, which is expressed as a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> average.

The data in Table II.A - 1 clearly indicate that the blowdown temperature tended to approach the current permit limit when hourly wet bulb temperatures remained above 76 0F for most of the day, or the daily average wet bulb temperature exceeded 76 0F. For example, the wet bulb temperatures exceeded 76°F for at least 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> on July 4, 5, 6, and 31, and August 1 and the daily average blowdown temperature equaled or exceeded 95.30F.

On these days, the blowdown temperature for several hours of the day exceeded the numerical value of the current permit (97.1 OF ) limit by more than 20F.

The data for July 1999 are not sufficient for precisely predicting when (or to what extent) occurrences of adverse meteorological conditions will result in blowdown temperatures that exceed the current permit limit for discharge temperature.

Hourly blowdown temperatures begin to trend towards 97.1 OF when either (or both) the wet bulb temperature and/or relative humidity are outside the design values for periods of approximately 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. (For example, see the daily summaries for July 9, 18, 19, 26, 27, and 30 that are attached to Table II.A -1.

Hourly blowdown temperatures showed a perceptible increasing trend into the mid-nineties when the wet bulb temperature exceeded 76 0F or the relative humidity dropped below 60% for periods of approximately 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or longer).

The margin of compliance with 97.1 OF (on a hourly basis), however, is highly variable. This variability is dependent on the severity of the adverse

meteorological conditions, and may also be affected by antecedent water temperatures in the basin and local winds that disturb the air-flow through the tower.

Until the results of the cooling tower performance test are available, PSE&G proposes that the current permit limit for temperature be stayed for any day when the wet bulb temperature exceeds 76.00 F for more 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. On these days, the blowdown temperatures will primarily be due to meteorological conditions (See Attachment II.B) rather than the Station's power level. A longer period will not have an effect on the final average blowdown temperature, and would only increase the risk of reporting a violation that is caused by natural factors that are outside the Station's control.

Attachment II.B Relative Effects of Meteorological Conditions and Station Power on Blowdown Temperature The current thermal limits for the cooling tower blowdown effluent were based on a hydrothermal study of the blowdown from Hope Creek Cooling Tower (HCCT).

The study was performed by J. E. Edinger Associates Inc. (Edinger) in 1994 and included calculations of daily averages of TbIowdown, heat rejection rates, and ATHCCT. The calculations were made using observed meteorological conditions and three power levels (namely, 100%, 79% and 50%) for each day of a 46 year period (1948 to 1993).

The hydrothermal studies indicated that the discharge (blowdown) temperature is dependent primarily on meteorological conditions and much less on heat load from the Station (or equivalently, the Station's power level). Figure II.B - 1 is a graph of daily average discharge temperatures that would occur if the Station were operating at 79% power (shown in blue) and 50% power (shown in red) versus the corresponding daily average temperature that would occur if the Station were operating at 100% power (which is plotted on the X-axis).

The graph contains two sets of points; each set contains computed discharge temperatures for each day of the 46-year period. One set compares the daily average discharge temperature for 79% power to the corresponding discharge temperature for 100% power. The second set is a similar comparison of the discharge temperature at 50% power to the corresponding discharge temperature at 100% power. Superimposed on the plot is a line along which all points would fall if discharge temperatures were totally independent of power level. When the discharge temperature is well below the current permit limit (97. 1OF), the points fall below the line. This result indicates that slightly higher discharge temperatures occur at 100% power. However, when the discharge temperature approaches 97.1 OF, the discharge temperatures for the three power levels fall nearly on the line. This result indicates that the meteorological

conditions are the primary determining factor, and the discharge temperature is nearly independent of power level. Thus, under adverse meteorological conditions, a reduction in the Station's power will not result in a blowdown temperature that meets the current permit limit.
