Subject:

Limerick Generating Station, Units 1 and 2 Changes to National Pollutant Discharge Elimination System Permit

Dear Sir / Madam:

This letter is being submitted in accordance with the Limerick Generating Station (LGS), Units 1 and 2, Environmental Protection Plan (EPP) Section 3.2, which stipulates that the NRC shall be notified within 30 days following the date of approval of a change to the National Pollutant  !

Discharge Elimination System (NPDES) permit.

By letter dated May 18.1999, the Pennsylvania Department of Environmental Protection (PA DEP) amended Bradshaw Reservoir NPDES Permit No. PA0052221. The Bradshaw Reservoir facility supports the operation of Limerick Generating Station (LGS), Units 1 and 2. The amendment to NPDES Permit No. PA0052221 reflects modifications to the monitoring frequency for dissolved oxygen, fecal coliform, and pH. The NRC was previously notified regarding the pending changes to the NPDES permit by letter dated December 9,1998.

Accordingly, this letter provides the required notification of a change to the NPDES permit and is being submitted within 30 days of the permitting agency's approval in accordance with the requirements of the LGS EPP. A copy of the PA DEP letter amending the Bradshaw Reservoir NPDES permit is attached.

If you have any questions or require additional information, please do not hesitate to contact us.

Very tr;ly yours,

Re: IW NPDES Permit PA0052221 Amendment No. I Bradshaw Reservoir Release Bedminster Township Bucla County

Dear Mr. Matty:

Referenced amended permit pages 1,2 and 2a are enclosed.

Please study the amended permit pages carefully and substitute these pages numbered pages in your permit issued Novrmber 9,1998. Please direct any questions to the Section of this office.

This amendment rebects modifications to the monitoring frequency for d coliform and pH. A minimum of five samples must be collected every month at Outfall 001 analyzed for these parameters. The sampling period for these parameters is May to Sep fecal coliform level shall not exceed a geometric mean of 200 col. per 100 milliliters based consecutive samples, each sample collected on different days.

Sincerely,

9. Enter " Sample Type" both as

• Sample Measurement" (actual sample type used during monitoring period) and as " Permit Requirement,"(e.g., Enter " Grab" for individual sample, "24HC" for 24-hour composite, "N/A " for continuous monitoring, etc.)

10. Where violations of permit requirements are reported, attach a brief explanation to describe cause and corrective actions taken, and reference each violation by date.

Use the sampling event reported concentrution .md perfo'rm the appropriate calculation as follows:

concentration (pg/l x 0.00834 x 3 flow (million gallons / day)= lb/ day or ,

concentration (mg/l) x 8.34 x flow (million gallons / day) = lb/ day The value assigned tofflow (million gallons / day)" should be the 24-hour average flow for the outfall on the day the sample was taken. Where an outfall discharges for only pan of a day (x hours), the daily mass value should be determined by using the x-hour average flow.

To Calculate an Arithmetic 'Aversee or Mean Use the following equation: -

Xs + X1 + Xs + Xa +...Xx

' five samples were analyzed, their results were 75,82,90,70, and 85. , / .3 75 '+ 82 + 90 + 70 + 85 1

INSTRUCTIONS FOR UTILIZING _ ,

NATIONAL POLLUTANT DISCHARGE ELTuTNATION SYSTEM (NPDESi DISCHARGE MONITORING REPORT (DMR) .

The original DMR form (s) included with your permit are provided to serve as a master. Copies of this form must be used when reponing the results of the monitoring requirements in your permit. Do not write on or send the original master. If you receive computer generated preprinted DMR forms. they should be used in place of the enclosed forms.

Please make 'a note of your permit expiration date on the master DMR so that you will be reminded to submit your renewal application 180 days prior to expiration.

A " Monitor / Report" requirement contained in a permit requirement block indicates that the parameter is monitored and the test result reported in the appropriate block. Any test methods specified in Part A or Part C of the permit must be used. ,

. An " Average Weekly" value is defined as the highest weekly arithmetic average value observed during the monthly monitonng period.

Loading or mass units shall be reported as the average of the calculated daily loadings during the monthly, weekly,0. :!.aily measurement pe,riod. .

For parameters for which the effluent limit is lower than the Method Detection Limit (MDL) of the most sensitive existing EPA approved (40 CFR Part 136), test method or DEP approved method, the parameters -

should be analyzed using the test method specified in Part C of the permit. The sample results must be specified on the DMR form as either the measured (quantified) value or as "less than" the detection limit used in the test (e.g. < x.x). Results SHALL NOT be reported as "Not Detectable" or "ND". For computing monthly averages, all "less than" sample results may be counted as zero values. All sample results used in computing monthly average values must be reported on the DMR form in the DMR comment section.

You should also note any other special instructions or definitions contained on the front and back of the DMR as well as in the permit.

Submit the completed forms to: DEP, EPA and the County Health Department as required in the permit. Unless otherwise specified in the permit, the DMR form must be submitted each month. If there is no discharge during the month, the DMR must be submitted with "NO DISCHARGE" written across the front.
