1.3.2

A land use census shall be conducted and shall identify the location
of the nearest milk animal, the nearest residence and the nearest
garden1 of greater than 500 square feet producing vegetables in each
of the 16 meteorological sectors within a distance of 5 miles. (For
elevated releases as defined in Regulatory Guide 1.111, Revision 1,
July 1977, the land use census shall also identify the locations of
all milk animals and gardens of greater than 500 square feet producing
fresh leafy vegetables in each of the 16 meteorological sectors within
a distance of three miles.)

1 Broad leaf vegetation sampling may be performed at the SITE
BOUNDARY in the direction sector with the highest D/Q in lieu of the
garden census.

APPLICABILITY: At all times.
ACTION:
With a land use census identifying a location(s) which yields a calculated
dose or dose commitment greater than the maximum value currently being
calculated in Section 7.5, identify the new location(s) in the next Annual
Radiological Environmental Operating Report.
With a land use census identifying a location(s) that yields a calculated
dose or dose commitment (via the same exposure pathway) 20 percent greater
than at a location from which samples are currently being obtained in
accordance with ODCM Control 1.3.1, add the new location(s) to the REMP
within 30 days if the owner consents. The sampling location(s), excluding
the control station location, having the lowest calculated dose or dose
commitment(s) (via the same exposure pathway) may be deleted from this
monitoring program after October 31 of the year in which this land use
census was conducted. Identify the new location(s) in the next Annual
Radiological Environmental Operating Report and provide a revised
figure(s) and table(s) reflecting the new location(s).

SURVEILLANCE REQUIREMENTS

2.3.2

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 mrem per year
isodose line, whichever is larger, enumeration by a door-to-door or
equivalent counting technique.

2.

Within a 5-mile radius from the plant, enumeration by using
appropriate techniques such as door-to-door survey, mail survey,
telephone survey, aerial survey, or information from local
agricultural authorities or other reliable sources.

BASES

1/2.3 RADIOLOGICAL ENVIRONMENTAL MONITORING
1/2.3.1 MONITORING PROGRAM (continued)
radiological effluent monitoring program by verifying that the
measurable concentration of radioactive materials and levels of
radiation are not higher than expected on the basis of the effluent
measurements and modeling of the environmental exposure pathways. The
REMP satisfies the requirements of 10 CFR 50, Appendix A, Criteria 64
and 10 CFR 50, Appendix I, Section IV.B.2.

1/2.3.2 LAND USE CENSUS
This requirement is provided to ensure that changes in the use of
UNRESTRICTED AREAS are identified and that modifications to the
monitoring program are made if required by the results of this census.
The best survey information from the door-to-door, mail, telephone,
aerial or consulting with local authorities shall be used. This
census satisfies the requirements of Section IV.B.3 of Appendix I to
10 CFR Part 50. Restricting the census to gardens of greater than
500 square feet provides assurance that significant exposure pathways
via the leafy vegetables will be identified and monitored since a
garden of this size is the minimum required to produce the quantity
(26 kg/year) of leafy vegetation assumed in Regulatory Guide 1.109 for
consumption by a child. To determine this minimum garden size, the
following assumptions were used: 1) that 20% of the garden was used
for growing broad leaf vegetation (i.e., similar to lettuce and
cabbage), and 2) a vegetation yield of 2 kg/square meter.

1/2.3.3 INTERLABORATORY COMPARISON PROGRAM
The requirement for participation in an Interlaboratory Comparison
Program is provided to ensure that independent checks on the precision
and accuracy of the measurements of radioactive materials in
environmental sample matrices are performed as part of the quality
assurance program for environmental monitoring in order to demonstrate
that the results are reasonably valid.

9.1 MONITORING PROGRAM DESCRIPTION
A Radiological Environmental Monitoring Program (REMP) as described in
Tables 9.1, 9.2, and 9.3 and in Figures 9.1, 9.2, and 9.3 shall be
conducted. Results of this program shall be reported in accordance with
ODCM Administrative Control 5.1.
The atmospheric REMP shall consist of 11 monitoring stations from which
samples of air particulates and radioiodine shall be collected.
The terrestrial monitoring program shall consist of the collection of
milk, soil, drinking water, and food crops as provided in Tables 9.1 and
9.2. In addition, direct gamma radiation levels will be measured at 40 or
more locations in the vicinity of the plant.
The reservoir sampling program shall consist of the collection of samples
of surface water, sediment, and fish.
9.2 DETECTION CAPABILITIES
Analytical techniques shall be such that the detection capabilities listed
in Table 2.3-2 are achieved.
9.3 LAND USE CENSUS
A land use survey shall be conducted in accordance with the requirements
in Control 1.3.2. The results of the survey shall be reported in the
Annual Radiological Environmental Operating Report.
9.4 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.
If analyses are not performed as required corrective actions taken to
prevent a recurrence shall be reported in the Annual Radiological
Environmental Operating Report.
