Dear Ms. Wachter:
The purpose of this letter is to respond to your March 8, 1989 notice concerning certain Discharge Monitoring Reports (DMR's) for beaver Valley Power Station.
I With respect to the column marked "No. Ex. (62-63)," in the guidance on the back of the DMR, it instructs the permittee to report "the number of sample measurements during (the) monitoring period that exceed maximum and/or minimum or 7-day average as appropriate permit requirement for each parameter.
1 If
- none, enter 0."
On the January, 1989 and May, 1988 DMRs, neither maximum or minimum permit limitations were exceeded.
As
- such, we entered "0"
in column 62-63.
Thus, we believe we are completing the DMR's as intended.
If the Departments' position has changed on this issue, please inform us of such.
i Until further
- notice, all violations of the monthly average values will be noted on the discharge monitoring reports and letters of explanation will be attached.
With regards to the noted violations of the monthly averages, the following information is provided:
i Discharge
- 203, the Unit 1 sewage treatment plant exceeded the
. monthly average specification with respect to total suspended solids (35.6 mg/1) and Feccl Coliform (205 colonies /100 ml) 4 during the month of May 1988.
Subsequent to the high sample l
measurements of 54.9 mg/l total suspended solids on the 26th and
)
205 colonies /100 ml Fecal Coliform on the 27th, the sewage plant j
flows were adjusted to increase recirculation and the chlorine dose rate was increased.
Samples for total suspended solids on the 27th showed 22.4 mg/l and a sample for Fecal Coliform on the
]
31st of May indicated 193 colonies /ml.

l In January
- 1989, the Unit 1 sewage treatment plant, Discharge
- 203, also-exceeded the monthly average specification with respect.to total suspended solids (44.05 mg/1).
The flows were again adjusted-and due to minimal influent flows, chemicals were added to increase pH and to increase growth on the RBD.
The requested operating data on Outfall 203, the Unit 1 sewage treatment
- plant, is attached for your review.
If you have'any further questions concerning this
- matter, contact David A.
Orndorf at (412)393-5113.
