June 26, 1987 Sanitary Engineer CH-87-879 State of Connecticut Department of Environmental Protection l Water Compliance Unit 122 Washington Street Hartford, Connecticut Re: Infcrmation letter on Demineralized Water Discharge In follow to our conversation on Monday, June 22, 1987, here is a chronology of the event involving a discharge of demineralized water at Connecticut Yankee on June 20, 1987.

At approximately 0810, a level transmitter tap was broken off the primary water storage tank, which contained approximately 140,000 gallons of deminera-lized water.

Flowing ground samples were taken and analysed. NPDES required analyses were run, and all were in specification with exception of pH, which was 5.8.

The volume discharged was 140,000 gallons, all of which flowed to the plant discharge canal. The duration of discharge was ten hours.

The water flowed over a black-topped surface, then down a canal bank; no surface erosion was noted.

Should you have any questions concerning this event, please call me at 267-2556, j Ext. 430.

Sincerely, Michael D. Quinn Chemistry Supervisor MDQ/a1 cc: PIR 87067 File N. J. Lanzallotta ,
