SUBJECT:

Overflow of Sewage Line, Limerick Generating Station, NPDES Permit No. PA-0051926

Dear Mr. Bower:

On April 4, 1989, at approximately 11:00 a.m., a sewage line from the Personnel Processing Center backed up. Sewage overflowed to a nearby storm drain. The discharge entered. Possum Hollow Creek at outfall-012 and ended at aboutil2:45 p.m. A visual inspection was made at outfall 012 and downstream of the outfall to determine impact to the environment. There was no visible evidence of a sewage discharge.

The initial notification was made to Mr. Dave Arnold of the Department of Environmental Resources, Norristown Office at 1:45 i p.m. on April 4, 1989. Mr. Arnold was informed of our intent to wash down the affected area, including the storm drain piping, with unchlorinated well water. ,

l A second telephone call was made to Mr. Bob Bower of the DER

( on April 6, 1989. A waiver of the 5 day written notification was received at that time.

The Personnel Processing Center inputs to the sanitary waste  ;

system were isolated as soon as the problem was evident. Site personnel responded to the incident by removing sewage accumulated above the blockage and clearing the blocked line. -;

Non-chlorinated well water was used to flush the storm drain -

lines through to Possum Hollow. Upon clearing the blockage in .

the sewage line, the system was returned to normal operation. I 1

The maximum volume discharged was estimated at 2000 gallons based on UPC/ BOCA standards for the number,of fixtures located in the building and a 20 minute surge time. The actual volume discharged was probably much less.

This was an isolated. incident, not a result of neglect'or personnel ~ error. Should~ indications of a recurrence arise; a i vendor.will be called in to inspect and clean the lines.

Sincerely, C \
