'2 In our letter to you. of February 23, 1976, providing guidance on implementin~

the requirements of Appendix I to 10 CFR Part 50, we indicated that the staff was preparing additional guidance regarding the formulation of Technical Specifications to implement Section V.B.2 of Appendix I".

In this regard we have attached guidance on the preparation of your proposed Technical Specifications.

It should be noted that these draft Technical Specifications will require modification to incorporate plant specific information.

Additionally, due to the draft nature of these Technical Specifications there are certain areas which have already been identified by the staff for further study and possible modification.

These areas are listed in the "Forward" to the attached "Draft Model Technical Specifications".

We would be pleased to meet with you after the June 4,

1976 submittal date to discuss your methods of evaluation to show conformance with Appendix I and your proposed Technical Specifications for the purpose of keeping releases of radioactive materials in effluents as low as reasonably achievable.

Sincerely, Original signe<l by K. I<niel Karl Kniel, Chief Light Water Reactors Brancn Mo.
