Letter (C04782), NPDES Permit No. CT0003123, Haddam Neck Plant, i Connecticut Yankee Atomic Power Company, dated September 30,1992. ;
Haddam Neck Plant April 1997 Monthly Discharge Monitoring l l
Connecticut Yankee Atomic Power Company herein submits the attached report for the month l I
of April 1997. Paragraph 4 of the NPDES Permit, Reference, requires that discharges from the permitted facility be monitored according to a specified schedule and results be reported to the Director of Water Compliance each month. Any variations from the permit are explained in the section headed "Results and Discussions" enclosed.
Additional samples that have been taken at NPDES locations and analyzed with approved methods are included in Table 2 and 3.
Should you have any questions or require further information, please all Mr. Paul Jacobson, Northeast Utilities Service Company, Environmental Services at (860) 447-1791, Extension 2335.

This repon fulfills the monitoring requirements for the Haddam Neck Plant (Connecticut i Yankee), NPDES Permit No. CT0003123, dated September 30,1992. DMRs will be submitted '
as soon as compiled, but not later than the last day of the month following the report period as I stated in the permit. !
I l
Results and Discussions Results of the continuous, weekly and monthly monitoring programs are summarized on the ;
DMR sheets attached. All sampling and analysis except hydrazine, ethanolamine and boron :
were conducted in accordance with EPA approved procedures set forth in EPA Publication i 600/4-79-020. For these three chemical substances, CYAPCO submitted its own procedures to DEP for approval on October 4,1996.
The computerized data logging repon of the continuous monitoring program is included in Table 1. This repon is included because it provides data for the daily range of pH, temperature, i and flow; which are required under the NPDES permit. The DMR form does not have provisions for daily ranges. !
Oil Soill On April 25,1997 at 9:15 a.m., a spill of approximately one half gallon of oil was discovered in the Connecticut Yankee parking lot by plant personnel. The cause of the spill is unknown.
j Required verbal notifications were immediately made, and a written report was set to the DEP on April 30,1997 (D11066).
i DSN 001H. PCB Analvsg On April 29,1997 the semi-annual stormwater sample for DSN 00lH was collected. Of the various substances required to be monitored, only the analysis for PCB's is performed off-site.
However, due to trace amounts of radioactivity in this sample, it could not be sent off-site for PCB analysis. Another sample will be taken in the near future and the results will be included in that month's DMR. All other parameters were analyzed and are included in this report.
