PROPOSED QIANGE TO TECID11 CAL SPECIFICATIONS APPENDIX A, OF PROVISIONAL !

OPERATING LICDiSE DPR 22 Pursuant to 10 CFR 50.$9, the holders of Provisional Operating License DPR-22 hereby propose the follotting change to Appandix A Technical Spe-cifications:-

SpecificatJton and Bases 3.8/4.0F-Environmental Monitoring Program fROPOSED CHANGE Replace Table 4,8.1, Sample Collection and Analysis, Monticello Nuclear Plant Environmental Monitoring Program with the proposed Table 4.8.1 contained in Exhibit D. Add Figutes 4.8.1 and 4.8.2 and replace page 179B, 3,8/4.8 Basts, as contained in hhibit B.

REASON TOR CHANGE Members of the NRC Staff working with NSP personnel developed a modified scope for the Monticello Radiation Environmental Monitoring Program con-sistent with current Regulatory guidance and utilizing the indicator-con-trol concept.

Revised Table 4.8.1 describe _s the updated program consistent with NRC requirements that should be implemented for the Monticello plant.

SAFETY EVALUATION Technical Specifications on effluent releases have been issued at Monticello to keep levels of radioactive materials in effluents as low as practicable to insure that radiation doses to the public resulting from these releases will continue to remain minimal. Technical Specification for the measure-ment of the level of these radioactive releases, together with dispersion estimates, ensure that these plant releases to the environment and radiation doses to the public are maintained as low as practicable. The radiation environmental monitoring program provides supporting evidence for assessing the performance of the plant with respect to keeping population' exposures as low as practicable. Therefore, the radiation environmental monitorirg program, and changes thereto, involve no significant hazards considerations.

The revised monitoring program is adequate to provide the necessary sup-porting evidence since it is based upon current Regulatory guidance on measuring radiation levels and _ radioactivity in the environs.

a Bases Continued: I The frequency for monitoring or sampling has been established so that if the nuu:imum amount of gross radioactivity is exceeded, action can be taken to reduce the radioactivity to a level below the speci-fled limit. .

F. Radiation Environmental Monitoring Program The types of samples, the number and distribution of collection sites,and the types of analysis specified will provide data, which compared with preoperational background data, will vaify the effectiveness of plant ef fluent control and indicate any measurable changes in environmental radioactivity due to plant operation.
