EXEMPTION I.
The Baltimore Gas and Electric Company (the licensee) is the holder of Facility Operating License Nos. DPR-53 and DPR-69 which authorize operation of the Calvert Cliffs Nuclear Power Plant, Unit Nos. I and 2.
These licenses provide, among other things, that they are subject to all rules, regulations and Orders of the Commission now or hereafter in effect.
The facility comprises two pressurized water reactors at the licensee's site located in Calvert County, Maryland.
II.
Appendix J to 10 CFR Part 50, " Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors," includes schedular and technical requirements for the conduct of " Type A" reactor containment Integrated Leak Rate Tests (ILRTs). With regard to schedule for ILRTs, Appendix J Section II.D.I.(a) requires that "... three Type A tests shall be performed, at approximately equal intervals during each 10-year service period. The third test of each set shall be conducted when the plant is shutdown for the 10-year plant inservice inspections."

1 By application dated August 15, 1985 the licensee requested a change to the ILRT schedule, as specified in Appendix J, Section ill.D.l.(a) to allow the third ILRT to be conducted prior to the 10-year ISI outage. The proposed exemption to Appendix J,Section III.D.1.(a) would only affect the scheduling of one of three Type A tests during each 10-year service period; the scheduling of the two remaining Type A tests would not be affected. The maximum impact of scheduling on the third Type A test would be minor and amount to the duration of one refueling cycle. Moreover, the impact wculd not be cumulative since each 10 year service period would start a new Type A test schedule. The remaining schedular requirements of Appendix J Section III.D.1.(a), "...three Type A tests shall be performed, at approximately equal intervals during each 10-year service period," which is of principal importance, would remain in effect.

III.
Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12, an exemption is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest and hereby grants the following exemptions with respect to the requirements of Appendix J to 10 CFR Part 50:
With regard to the third ILRT of a 10-year service period, this ILRT need not be conducted when the plant is shut down for the 10-year plant inservice inspection.
Pursuant to 10 CFR 51.32 the Commission has determined that the issuance of the exemption will have no significant impact on the environment (50 FR 40632).
