-3.0 Radiological Environmental Monitoring 3.1 Monitoring' Program An-environmental radiological monitoring program shall be conducted in accordance with Technical Specification 3.12.1. The monitoring program described in Tables 3.1, 3.2, and 3.3, and in Figures 3.1, 3.2 and 3.3 shall be conducted. Results of this program shall be reported in accordance with Technical Specifications 6.9.1.6 and 6.9.1.7.

The atmospheric environmental radiological monitoring program shall consist of monitoring stations from which samples of air particulate and atmospheric radiciodine shall be collected.

• • The terrestrial monitoring program shall consist of the collection of milk, soil, ground water, drinking water, and food crops. In addition, direct gamma radiation levels will be measured in the vicinity of the plant.

The reservoir sampling program shall consist of the collection of samples.of surface water, sediment, clams, and fish.

Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, sample unavailability, or to malfunction of sampling equipment. If the latter, every effort shall be made to complete corrective action prior to the end of the next sampling period.

3.2 Detection capabilities

. Analytical techniques shall be such that the detection capabilities listed in Table 3.4 are achieved.

3.3 Interlaboratory Comparison Program Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program which has been approved by the NRC. A summary of the results obtained in the intercomparison shall be included in the Annual Radiological Environmental Operating Report (or the EPA program code designation may be provided). -.

I If analyses are not performed as required corrective actions taken to prevent  :

a recurrence shall be reported in the Annual Radiological Environmental Operating Report.

3.4 Land Use Census A land use survey shall be conducted in accordance with SQN Technical Specification 3/4.12.2. The results of the survey shall be reported in the Annual Radiological Environmental Operating Report.
