PA0051926 to permit the use of a new chemical additive (i.e., Betz Bio-Trol 88P). This new chemical additive will be used as an alternative to the chlorine and bromine system currently permitted for controlling maln condenser biofouling. A copy of the PA DEP letter approving this change to the LGS NPDES perrait is attached. The NRC was previously notified of our request to revise the NPDES permit to use the chemical add!tive Betz Bio-Trol 88P by letter dated October 19,1995.

Dear Mr. Matty:
This is in response to your October 19,1995 letter requesting approval to use chemical additive Betz Bio-Trol 88P in the cooling water system at the subject facility. The additive will be used as an alternative to the chlorine and bromine system currently permitted for the control of condenser biofouling. The wastewater will be discharged at an average flow of 14.27 mgd to the Schuylkill River through Outfall 001.
We have completed our review of the information submitted and hereby approve your request to use Betz Bio-Trol 88P subject to the following conditions:
1.
The concentration of total residual oxidants at Outfall 001 shall not exceed 0.2 mg/l. A weekly grab sample shall be collected at the Outfall and be analyzed for total residual oxidants. The analysis report shall be submitted monthly on the Discharge Monitoring Report form.

The term " total residual oxidants" for water with bromides generated through the use of chemical additive Bio-Trol 88P is defined as the value obtained using the amperometric method for total residual chlorine as described in 40 CFR Section 136. This method is -
described in Standard Methods as the ' amperometric titration method".
3.
Discharge containing chemical additive to control corrosion, scaling. algae, slime,
. fouling, oxygen, etc. shall be managed by the permittee to ensure that toxic effects in the receiving stream are prevented. Usage rates shall be limited to the minimum amount necessary to accomplish the intended purposes of chemical addition.
4.
Accurate records of usage (name of the additive, quantity added, date added) of the i
approved chemical additive and blowdown discharge volumes must be maintained on the Chemid Additive Reporting Form and be kept on-site by the permittee.
5.
The NPDES permit will be revised to include this approval upon permit renewal.
