(ES) Ouquesne Light Company (HUN) Shippingport Borough (AF) Beaver Valley Power Station (CO) Beaver This is a renewal application for the Beaver Valley Power Station located on the Ohio River. Units #1 and #2 are atomic powered generating stations. The applicable effluent limitation guidelines are 40 CFR 423 - Steam Electric. F.R. Volume 47, November 19, 1982. BCT guidelines for this category have not yet been promulgated.

Therefore, in all cases BCT has been assumed equivalent to BPT based on infonnation from EPA that BCT, when developed will probably be equivalent to BPT.

Effluent Limitation Rationale Technology Effluent Limitations Internal Monitoring Point 101 con $6sts of a 0.0264 mgd discharge from the chemical waste treatment system which includes demineralizer regenerants, lab sink drains, and Unit #1 auxiliary boiler blowdown. The applicable effluent limitations are based on the federal guidelines for low-volume waste sources - 40 CFR 423.12(b):

Average of Daily Values For Maximum for Any 30 Consecutive Days Shall Not Exceed Pollutant One Day (mg/1) (mg/1)

Total Suspended Solids 100.0 30.0 Oil and Grease 20.0 15.0 Internal Monitoring Point 201 consists of a 0.0034 mgd discharge of softener regenerants. The applicable effluent limitation guidelines are 40 CFR 423.12(b) for low volume wastes (see Outfall 101).

Internal Monitoring Point 301 consists of 0.004 mgd discharge of the Unit #2 auxil-iary boiler blowd3wn. The applicable effluent limitation guidelines are 40 CFR 423.12(b) for low volume wastes (see Outfall 101).

Internal Monitoring Point 401 consists of a 0.001 mgd discharge from the Unit #2 chemical feed area drains. The applicable effluent limitation guidelines are 40 CFR 412.12(b) for low volume wastes (see Outfall 101).

Outfall 001 consists of a 35.2 mgd discharge of Unit #1 and Unit #2 cooling tower blowdown, Outfalls 101, 201, 301, and 401, treated radioactive waste, and occasional clarified water. The applicable effluent limitation guidelines are 40 CFR 412.13(d) for cooling tower blowdown:

The 126 priority pollutants contained in chemicals added for cooling tower maintenance. No detectable amount except:

Chromium 0.2 0.2

- Zine 1.0 1.0 It is the Department's understanding that the permittee does not add chromium or zine compounds to the cooling water. Therefore, no limitation or monitoring requirement has been placed on chromium or zinc, and the permittee is prohibited from adding chromium or zine compounds to the cooling water unless the permittee obtains an amendment to this permit.

Neither free available chlorine nor total residual may be discharged from any unit I for more than two hours in any one day and not more than one unit in any plant may discharge free available or total residual chlorine at any one time unless the util-

! i

! ity can demonstrate to the Regional Administrator or State, if the-5 tate has NPDES L permit issuing authority, that the units in particular location cannot operate at or' below this level of chlorination. '

Special Conditions in Part C of this permit restrict the discharge of the 126 prior-ity pollutants, free available and total residual chlorine, and the net aedition of pollutants to non-contact ~ cooling water. A condition has been placed in the permit for the permittee to obtain Deparbnental approval of chemical additives currently y used at the facility.

L No internal monitoring points (effluent limitation pages) have been placed in'the L

permit for Unit #1 and Unit #2 cooling tower blowdown. These were listed as unnum-bered process wastewater outfalls in-the application and will be renitored at 001.

Alternate test methods may be substituted as long as the method detection limit is achieved. If the analytical testing is received within the comment period, the Department may review it to detemine if Water Quality Based Effluent Limitations are necessary. Special Condition C-13 has been added to the permit to obtain the neces-sary data if the pemittee does not supply it within the conment period.

Thermal Effluent Limitations do not need to be imposed. A Special Condition to Part C of the pemit has been added to ensure that there is not a 2*F temperature rise in the receiving stream (in accordance with policy).

Other conditions contained in this permit include steps necessary to obtain approvn1 of chemical additives currently used at the facility. On June 13, 1990 the Department approved the use of Clam-trol (CT-1) and Betz DT-1 at the Beaver VaIIey Power Station. The approval was granted for a plan of study. Continual _use of the Betz products, will need a permit amendment.

t j- A flow monitoring report will be-requested during the draf t pemit period. This-l issue has been discussed with Duquesne Light (June 7, 1990) for the Phillips and Brunot Power Stations.

l Addendum to Fact Sheet 9/25/90 The Department offers the following connents to Duquesne Light's September 24, 1990 ,

submission regarding the draft permit for the Beaver Valley Power Station.  !

t The flow monitoring frequencies and sample type have been developed in accordance with the Department's Technical Guidance Chapter 6 - Developing and Specifying Self-Monitoring and Reporting Requirements in NPOES Pemits. These requirements will not change in the final pemit. Duquesne Light was to submit a flow monitoring pro-gram which was to outline the measures in place now at all of these outfalls. This information was to be submitted at the conclusion of the draf t connent period, not by October 15, 1990.

Duquesne Light failed to submit the sample analysis to support the claim that hydra-zine is not going to be discharged. A test monitoring program should be submitted to the Department for review. The scope of this program should be similar in nature to those required at the Phillips and Brunot Power Stations.

Oil and Grease effluent limitations will remain in the permit. Permit limitations must be established for every pollutant regulated in an applicable effluent limita-tion guideline.

In Specifying Permit Limits Based on the Water Quality Analysis Model (January 14, 1987, Revision May 11, 1987) "The EPA has confirmed the difference between CB005 and 8005 in its definition of secondary treatment. An equation has been established whereby, or average strength wastewater effluents after secondary treatment CB005* 1 B005 - 5 mg/l (where effluent B005 is 20-25 mg/1). The 5 mg/l represents the nitrog-enous fraction'of the B005. The limits will remain 25 and 50 mg/1, monthly average, daily maximum respectively.

Since Outfall 003 is submerged, the monitoring frequencies and effluent limitations  !

will be maintained at internal monitoring points 103, 203, 303, and 403.

The description for outfall 004 has been changed as requested.

l l Since Outfall 013 is submerged, the monitoring frequencies and effluent limitations will be maintained at internal monitoring points 113, 213, 313 and 413.

I

Page 8 of 8 FACT SHEET / STATEMENT OF BASIS NPDES PA0025615 (ES) Duquesne Light Company (HUN) Shippingport Borough (AF) Beaver Valley Power Station (CO) Beaver Requirement C-11 will not be modified as requested. As discussed previously. 60 days is adequate time to complete this requirement.

The language in Condition C-13 has been clarified. Four samples has been changed to four monitoring reports.

Total Suspended Solids effluent limitations have been placed e9 internal monitoring point 501.

2. DEFINITIONS

a. The ' average monthly" mass discharge means the total discharge by weight during a calendar month divided by the number of days in the month that the production or cocinercial facility or sewage facility was operating. Where less than daily sampling is required by this permit, the average monthly mass discharge shall be determined by the sunTnation of all the measured daily discharges by weight divided by the number of days during the calendar month when the measurements were made,

b. The " average weekly" mass discharge means the total discharge by weight during a calendar week divided by the number of days in the week that the facilit was operating. Where less than daily sampling is required by this permit, the average weekly mass discharge shall be determined by th6 suntnation of all the measured daily discharges by weight divided by the number of days during the calendar week when tha measurements were made.

c. The " maximum daily" mass discharge means the total discharge by weight during &cy calendar day.

d. The " average monthly" concentration means the arithmetic average of all the daily deteminations of concentration made during a calendar month,

e. The " average weekly" concentration means the arithmetic average of all thedailydeterminationsofconcentrationmadeduringacategarweek.

f. The " maximum daily" concentration means the daily determination of con-centration for any calendar day.

g. The " daily determination of concentration" means either the concentra-tion of a composite sample taken during a calendar day or the arithme-tic average of all grab samples taken during a calendar day,

h. The " instantaneous maximum" concentration means the concentration not to be exceeded at any time in any grab sample,

i. The term " composite sample" means a combination of individual samples obtained at regular intervals over a time period. Either the volume of each individual sample is proportional to discharge flow rates. or the sampling interval (for constant volume samples) is proportional to the flow rates over the time period used to produce the composite. The maxinue time period between individual samples shall not exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> except that for wastes of a unifom nature the samples may be collected on a frequency of at least twice per working shift and shall be equally-spaced over a 24-hour period (or over the operattn; d3y if flows are of a shorter duration).

j. The term " grab sample" means an individual sample collected in less than 15 minutes.
