Reference:

Permit (C04876), Northeast Nuclear Energy Company NPDES Permit No.

CT0003263, dated December 14, 1992.

Dear Mr. Grier:

Millstone Nuclear Power Station NPDES Permit CT0003263 - Modifications The NPDES permit for Millstone Nuclear Power Station was renewed on December 14, 1992, reference.

Since the implementation of the new permit, several modification requests necessary for plant operation have come to light.

Most of these modifications deal with adding a contingency for increased discharges in the event of emergencies or outages.

These permit modification requests are listed on Attachment 1.

Also enclosed are the appropriate Form 2's.

pSNs 001B-6 and 001C-6 NUSCO is requesting that hydrazine in a concentration of 75 mg/l be allowed as a discharge from DSN 001B-6 and 001C-6.

Hydrazine is used in the Secondary cycle as a corrosion inhibitor and has been detected throughout the Secondary cycle in parts per billion concentrations.

Hydrazine along with chemical contaminants in the Condensate cycle is removed by the condensate polishers during the purification process.

When condensate polisher resin is regenerated hydrazine, which has been concentrated on the resin, is removed and is found in the regenerant waste water in parts per million concentrations.

DSN 001B-6 does not have provision for the discharge of hydrazine in the present permit.

DSN001C-6, however, does provide for the discharge of hydrazine from the auxiliary boiler blowdown.

In order to properly operate the condensate polishers for Units 2 and 3, it is an operational necessity to be able to discharge hydrazine from DSNs 001B-6 and 001C-6.

Toxicity test results for hydrazine have been conducted on these discharges. The results are attached.

Mr. James Grier D06534/Page 2 August 2, 1993 DSN 006 Northeast Utilities respectfully requests the DEP to reevaluate some of the limits set for copper, nickel, and zinc for DSN 006.

These metals are not added to this discharge as process chemicals.

They exist as corrosion products, or in the case of zinc, is added upstream to the domestic water supply of the facility.

This discharge includes the yard drains. The plant operating conditions and the flow rates for this system have kept limits from being exceeded in the past f ew months.

It is our concern that the limits that have been set may occasionally be exceeded during start-ups and transients if they are not modified.

At maximum flow of 300 gpm, zinc is presently limited to 0.24 ppm monthly average, and 0.49 ppm maximum daily concentrations.

A major contributor to this discharge is New London city water.

Zinc phosphate is added to city water up to approximately 5 ppm concentrations.

Documentation of this has been requested f rom the town and will be forwarded to you as soon as it is obtained.

This could contribute to the limits of the permit being exceeded.

At maximum flow of 300 gpm, nickel is presently limited to 0.27 ppm maximum daily concentrations and copper is presently limited to 0.058 ppm maxinum daily concentrations.

There are both nickel and copper in our plant piping systems and it is possible that higher levels of contamination fron corrosion products may exceed these 1imits during start-ups and transients.

Addition of DSN 017 Since the December 14, 1992 renewal of Permit CT0003263, NUSCO has been in the process of reviewing all site drawings and has 'also begun construction of a new technical services building.

While planning the drainage of roof runof f for the new building a nanmade swale dating to the original power plant site work was determined to be a feasible discharge route for the roof drains for the new building.

NUSCO hereby requests that DSN 017 be added to the permit.

The appropriate forms arc enclosed.

MCS Plun 2 Addition Request to use and discharge a Calgon Corporation corrosion inhibitor MCS plus 2 (formerly called EMCS +)

is hereby made.

The product MCS plus 2 would replace hydrazine in the closed cooling water of units 2 and 3.

The discharges affected would be DSN 001B-9 and DSN 001C-9.

Corrosion inhibition will be accomplished by use of a nonhazardous material with less toxic properties.

MCS plus 2 is composed of sodius nitrite (7.5%),

sodium molybdate dihydrate (7.5%)

and sodium tetraborate pentahydrate (1.5%).

i NUSCO requests an increase in the maximum daily flow from "2,738,000,000 gallon per day" to "2,950,000,000 gallon per day" to j

account for flow increases as defined on DSNs 001A and 001C below.

DSN 001A NUSCO requests an increase in tha maximum daily flow from "604,800,000 gallons per day" to "680,000,000 gallons per day."

The former f 2 ow was listed as an average flow.

When the permit was renewed maximum flows were used, however, the flow rate was not changed.

NUSCO requests that Paragraph 3B(4) state that " service water discharged by DSN001A ',.nto DSN001-A is continuously chlorinated."

This is to make it clear the service water chlorination is being done as permitted.

DSN 001A-1 NUSCO requests that " maximum frequency of discharge of 2" be added to 3C.

This will account for outage or emergency conditions.

DSN 001A-2 NUSCO requests that " maximum frequency of discharge of 3" be added to 3D.

DSN 001D NUSCO requests an increase to the maximum daily flow froin "820,000,000 gallons per day" to "870,000,000 gallons per day."

The former flow was listed as an average flow.

When the permit was renewed, maximum flows were ised, however, the flow rate was not changed.

NUSCO requests that paragraph 3J(4) state that service water discharged into DSN001B by DSN001B-5 is continuously chlorinated.

nootine analysis of samples discharged from DSN 001B-6 indicated a tuesonce of hydrazine.

Subsequent investigation found that hydrazine was being concentrated on plant Condensate Polishers.

Whon the Condensate Polishers are regenerated, this hydrazine is i

released.

A NPDES Permit Modification requesting the discharge of hydtazine and an Aquatic Toxicity test of DSN 001B-6 were l

initiated.

Thin report evaluates the aquatic toxicity of the effluents discharged from DSN 001B-6.

Effluents from 001B-6 are diluted by on1B before they are released to the quarry cut.

Samples were obtained at DSN 001B while a batch release was being made 001B-6.

Prior to the release, chemical analysis of 001B-6 showed from DSN hydrazine n

concentration of 4 ppm.

i Testing was conducted in accordance with the testing protocol described in EPA 600/4-85-013 of the Regulations of Connecticutand Sections 22a-430-3 and 22a-430 4 States AQencies.
