Results and Discussions NPDES Monthly Report - May 1997

! Introduction

' ~

i i i This report fulfills the monitoring requirements for the Haddam Neck Plant (Connecticut '

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 j stated in the permit.

Results and Discussions  !

t i

Results of the continuous, weekly and monthly monitoring programs are summarized on the 1

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 600/4-79-020. For these three chemical substances, CYAPCO submitted its own procedures to DEP for approval on October 4,1996. i i

4 i I

The computerized data logging report of the continuous monitoring program is included in l

t Table 1. This report is included because it provides data for the daily range of pH, temperature, l and flow; which are required under the NPDES permit. The DMR fonn does not have 3 provisions for daily ranges.

i ,

DSN001H.PCB Analysis t On April 29,1997 the semi-annual stormwater sample for DSN 00lH was collected.- Of the j

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. We believe we have found a solution to this problem and expect to be able to have i

analysis performed in the month of June. If the solution works, the analysis results will be reported in the June DMR.
