Dear Mr.'Beazley:

This letter is to inform you-of a non-compliance condition that-occurred at Calvert Cliffs Nuclear Power Plant. <

>On March 13, 1989 the main drain header of a building clogged, overflowing the floor drain onto the first floor. During the clean up.it was identified that s*ie cleaners had been dumping buckets of the waste water from- the backed up drains down an outside storm drain. This - storm drain bypasses the facility's sewage. treatment plant.

The cleaners were instructed to stop this action and to use the drains inside the^ building which had;been-cleared and were-reedy for use. .It is estimated that approximately 50 gallons of clean p waste water was dumped down'the storm drain.

The impact upon the receiving water (Chesapeake Bay) -is unknown. -The duration permit of-the non-compliance was approximately three . (3) hours. The cause of the non-compliance was the lack- of awareness - of - the NPDES Permit requirements by the l cleaning crew as well as'the-importance of:the control of any. type of-discharge from-the-facility. A letter' explaining.this matter has been sent to all of-: the concerned supervisors at the. f acility to insure that all employees.are informed of the importance of these controls.

If you have questions regarding this information, - please feel free-to call me, 301/260-4905.

Sincerely, i g .4e #
