Mr. Ronald Parise Ee: Maryland State Diccharge Fermit ho. Th-DP-0187A aM NPDES Permit No. MD 0002399 Dear Mr. Parine.
At 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br /> on January 6,1982, a backup sample was drawn from outfall.
002 of the Calvert Cliffs Nuclear Fover Plant, h confirmed a pH of 91, above the con:pliance limit of 9 0.
This. condition existed until 0800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br />
. on Januan 7,1982 when the pH vas found to be 8.2.
A report of this
. incident was verbally transmitted to your office on January 7, 3982 and this is the required written report.
The noncompliance was found to be a result-of a high ar=onia concentration in the yard oil interceptor, a major contributor to the flow frotn outfall 002.
Though ammonia is used extensively for pH control of the nteam system at.Calvert Cliffe, no direct cause of high smmonia in the yard oil inter-ceptor could be found.
An investigation for possible causes is continuing thcugh, with the noncompliance no longer occurring, little success is expect ed.
Very tr21y yours,
LLWY L. B. Russell Plant Superintendent LBR/GEB/feb h
