Dear Mr. Patrick:
NCrfIFICATION OF NONCOMPLIANCE WITH EFFLUENT LIMITATI(RIS - NFDEs PREMIT I
NO. IN0026450 - SEQUCYAH NUCLEAR PLANT Description of the discharge--Discharge No. 003 - Operational sewage treatmant plant affluent. A sample collected as Hey 21, 1980, and reported by the laboratory on May 27, 1980, contained 76 mg/l of BOD,
3 exceeding the maximum permit limitation of 45 mg/1.
Cause and period of the noncompliance--The flowmoter in the disaharge pipe from the sand filter became plugged. This caused the septic teak effluent to accumulate in the aand filter and fluidised the send filter for at least 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. The blockage was discovered and corrected on May 1, 1980. The affluent flows on May 2 and 3, 1980, were 0.0556 HGD
]
and 0.0618 NGD, respe.ctively, which were far in emesse of the systems design capacity of 0.0149 MGD. We believe that the blockage followed by the hydraulic overload caused a temporary reduction in the treatment efficiency of the system. A repeat sample collected on May 30, 1980, contained 34 mg/l of BOD, so the per W of noneemp h e has ended.
3 Steps taken to prevent recurrence of the noncomplyina discharge--Simca the treatment system appears to have recovered, ao further action will be taken.
Sincerely,
