'in accordance. with of-Section 22a-430-3(j)(11)(D) 'of the DEP's regulations.

The:

w);:exceedance was reported by telephone to Mr. Robert Kaliszewski, DEP Water Compli-4 ance Unit, on February'7, 1990.

On January 3; 1990;' the value-for iron of 3.12:mg/l-for Discharge Serial Number j

- 001-E,sWaterxTreatment Waste - Liquid Tank ' Discharge, exceeded the. maximum permit'

limit 1of 1.0'mg/1.w Also,- the value for total oil and grease of 16 mg/l. exceeded' "i

o L

theimaximum' permit 11mit of.15 mg/1.

The iron exceedance is believed to have occurred ~ fromt corrosion -in the s system - duringJ an extended ' shutdown.

The grab Lsample was taken from the collection. sump located _ before the pump suction and final. filter. - Had the ' sample been taken at _. its1 normal? sample _ point afteri the a

filter, the total. iron would have been below the: permit limit.

It is believed a

that the cause of the total oil and grease exceedance-was due.to a dirty oil / water rseparator.

p In' order to: prevent a reoccurrence, the established sampling procedure for Dis-charge Serial No.: 001-E will be reviewed with appropriate personnel.-

The-3

. oil / water separatorLis presently being inspected and cleaned as required.
