. location. The new location shall be added to the radiological environmental j

monitoring program within 30 days, if the owner consents. The sampling location, excluding the control station location, having the lowest i

calculated dose or dose commitment (via the same exposure pathway) may be deleted from this monitoring program af ter October 31 of the year in which this land use census was conducted.

c. The provisions of Specifications 3.0.3 and 3.0.4 are not applicable.

SURVEILLANCE REQUIREMENTS 4.12.2 The land use census shall be conducted at least once per calendar year  !

between the dates of April 1 and October 1 using the following techniques:

1. Within a 2-mile radius from the plant or within the 15-ares / year isodose line, whichever is larger, enumeration by a door-to-door or equivalent counting technique.
2. With a 5-m!1e radius from the plant, enumeration by using appropriate techniques such as door-to-door survey, mail survey, telephone survey, serial survey, or information from local agricultural authorities or other reliable sources.

JUSTIFICATIONS l

(1) Table 3.6-2 (Unita 1 and 2) l This change is necessary to correct an error in the technical specifications: valve FCV-77-20 was not included on the containment isolation valve lists. This valve is on the nitrogen supply line to the reactor coolant drain tank.

It is in series with a check valve. The valve is normally closed, f ails closed on a loss of air or control power and receives a containment phase A isolation signal. The valves for both units have been tested even though they were not included on the list.

(2) Channina the Resnonsibility for Effinant Tech Snees (Units 1 and 2)

This change gives the plant responsibility for implementing the quality assurance program for effluent monitoring at the plant site. This program was previously the responsibility of the Radiological Hygiene Branch (RHB) . The RHB is still responsible for implementing the quality assurance program for environmental monitoring conducted off site. This change is applicable to Sequoyah units 1 and 2.

(3) Land Use Census (Units 1 and 2)

The revision would allow the survey to be performed in a more efficient and timely manner, with greater potential for correlating the garden sampling with the survey re sults. It would retain the close surveillance of land use in critical areas near the plant and allow more latitude in the selection of counting techniques further away from the plant. It would also permit a more stable monitoring program, with changes being required only when the more critical dose estimates are exceeded.

(4) Technten1 Soecification 4.7.11.1 (Units 1 gnd 2)

This change is proposed to coordinate the fire suppression water system flush with the chlorination of the raw service water and fire suppression systems. The chlorination of these systems is seasonal, and the fire suppression system flush should be coordinated with (*,. This change will not l

degrade the performance of the fire suppression system.
