P. O. BOX 8699 PHILADELPHIA, PA 19101 (215) 841-4000 May, 26,1993 Mr. Sohan L Garg Department of Environmental Resountes Suite 6010, Lee Park 555 North Lane Conshohocken,' PA 19428

Dear Mr. Garg:

Limerick Generating Station NPDES Permit No. PA0051926.

As per our recent telephone conversation, we are requesting approval to test NALCO.7455, an anti-foaming -

- agent, in the cooling towers at Limerick Generating Station. Currently, we apply Betz Foam-trol.CT as per PaDER' approval. Through a competitive bid process, the NALCO product has been identified as a possible alternative to the Betz product. Before requesting that the permit be amended to allow for use of the, NALCO 7455, we would-

_ ~

like to run a full-scale test on the product. The test would entail injecting one SS-gallon drum of the product over a two week period. The suggested usage rate is 23 to 31 pounds per day with a maximum rate of 153 pounds per day.

Enclosed are the Maierial Safety Data Sheets and aquatic toxicity data for the NALCO 7455.' We are requesting that approval for the test be received by June 11,1993, in order that a decision can be made concerning -

the two chemicals prior to expiration of the current contract (for the Betz Foam-trol _CT).

A copy of this letter (including any attachments or enclosun:s) is being sent to the U.S. Nuclear Regulatory Commission (USNRC) in ace'ordance with the Limerick Generating Station, Units I and 2, Environmental Protection -

Plan, Section 3.2, which stipulates that the USNRC shall receive a copy of any proposed changes to the NPDES permit at the same time that the permitting agency is notified.

If you have any questions or require additional information, please contact me at (215) 841-5177.

Sincerely,

~

5. The density of this product is 7.41-7.66:1b/ gallon.

6. Cooling tower antifoam dosages are highly dependent 7upon water temperature, make-up water contaminant levels and' cycles of concentration. As such, the required dosage can vary over_a broad range. ;

These limitations :having been defined, based. upon' our '

exp'erience and on-site testing, the recommended dosage for '

Lthis product application is 3-4 gallons / day. This equates to 0.6-0.8 ppm assuming a blowdown rate of 3000 gpm.
