L. E. Minnick Change No. 90 Vice President License No. DPR-3 Gentlemen:
We have recently reviewed the effluent release data from the Yankee f acil--
ity. We have found that the isotopes of iodines and particulates with half-lives longer than eight days which have been released in the gaseous effluent from the Tankee plant have always been in amounts significantly below the concentration limits necessary to account for reconcentration in the milk chain. However, the required MPC reduction factor to determine the per-missible limit for these controlled gaseous effluent releases is not included in the Yankee Technical Specifications.
I Yankee has agreed to a proposed change in the Technical Specifications which would incorporate the required MPC reduction factor. The wording of the proposed change (designated Proposed Change No. 90) was discussed with Mr. Carl Andognini of your staff in a telephone conversation on l
February 11. 1970, and we understand that it is acceptable to Yankee l
Atomic Electric Company.
The proposed change does not involve hazards considerations not described or implicit in the safety analysis report, and there is reasonable assur-ance that the health and safety of the public will not be endangered.
Accordingly, pursuant to Section 50.59 of 10 CFR Part 50, paragraph 3 of Section D.2.g. of the Technical Specifications of License No. DPR-3 is changed as set forth in Attachment A.
Sincerely,
\\v b f

ATTACHMENT A Section D.2.g.
Paragraph 3 -- replace with the following:
(3) Gases - As determined at the point of discharge from the primary vent stack and averaged over a period not exceeding one year, the concentrations of radioactive gaseous wastes discharged shall not be in excess of 1000 times the limits specified in Appendix B, Table II, 10 CFR 20, except that for the isotopes of iodine and particulates with half-lives longer than eight days the values of MPC shall be reduced by a factor of 1/700. Any discharge to the atmosphere from the evaporator or the combustible waste incinerator shall be continuously monitored at or prior to the points of such discharge. The monitor in the incinerator stack shall be kept in continuous service in order to provide an alarm and a record in the event of the release of radioactive gas from the waste disposal blanket gas system through the loop seal.
