SUBJECT:
Limerick Generating Station 5
Chemical Spill on May 22, 1985 Gentlemen:
In accordance with the Department's Rules and Regulations, Chapter 101.2 " Incidents Causing or Threateing Pollution", telephone notification of the subject incident was given to Mr. Walter Stanley i
of the Department by John Franz, Superintendent-Operations, Limerick Generating Station, on May 23, 1985.
On May 22, 1985 approximately 300 gallons of water with a pH h
greater than 9.0 but less than 9.5 was discharged from NPDES discharge point 004.
This discharge point receives water from roof and yard drain systems only.
It has no specific effluent limitations or i
monitoring requirements.
l This event occurred while cleaning up approximately five gallons j
l of concentrated sulfuric acid that was spilled in the yard area.
The T
acid came from a delivery truck which was maneuvering while its tank l
top lid was open.
The Plant personnel immediately sprayed water and j
spread soda ash on the spilled acid, and subsequently washed the mixture from the pavement with water using a hose.
This mixture unintentionally flowed to an open yard drain and was subsequently sampled by Chemistry technicians at the discharge Outfall Point 004.
-i Grab samples were taken at 15 minute intervals.
Surface grab samples were also taken from Possum Hollow Run both upstream and downstream of 5
discharge point 004.
No environmental effects were observed. _The 5
period of time which the effluent pH level exceeded 9.0 was
~
approximately 60 minutes.
The entire acid spill area was thoroughly cleaned and the yard drain system continued to be flushed with fresh water for j
approximately three hours after the effluent was determined to be within the 6.0 to 9.0 pH range.

b-2850615290 The following actions were accomplished to prevent future occurrences:
l 1.
The acid delivery truck driver was reminded that _the tatik top f
lid should not be left open while maneuvering the truck.
I 2.
Individuals involved in this event received instructions regarding the need to' assure acceptable conditions exist before washing potentially hazardous substance in such a manner that it could flow to untreated and unmonitored drain systems.
3.
This event and its potential consequences were discussed in detail with operations and chemistry department personnel.
4.
A Special Event procedure for Pollution Incident Protection is being developed.
The purpose of the procedure is to provide guidance on how to respond to the discovery and handle the clean up of a hazardous substance discharge or spill.
This procedure is expected to be approved and issued for use by June 14, 1985.
Very truly yours, W. T. Ullrich Superintendent Nuclear Generation l
