RADIOLOGICAL ENVIRONMENTAL MONITORING

1.3.2

LAND USE CENSUS
CONTROLS
A Land Use Census shall be conducted and shall identify within a distance of 8 km (5 miles)
the location in each of the 16 meteorological sectors of the nearest milk animal, the nearest
residence, and the nearest gardena of greater than 50 m2 (500 ft2) producing fresh leafy
vegetables.
a Broad leaf vegetation sampling of at least three different kinds of vegetation may be performed at the SITE
BOUNDARY in each of two different direction sectors with the highest predicted D/Qs in lieu of the garden
census. Specifications for broad leaf vegetation sampling in Table 2.3-1 shall be followed, including analysis of
control samples.

APPLICABILITY:

At all times.

ACTIONS
NONCONFORMANCE

CONTINGENCY MEASURES

A. Land Use Census
identifying a location(s)
that yields a calculated
dose or dose
commitment 20% greater
than at a location from
which doses are
currently being
calculated in ODCM
Section 7.3 and 7.4.

A.1

B. Land Use Census
identifying a location(s)
that yields a calculated
dose or dose
commitment (via the
same pathway) 20%
greater than at a location
from which samples are
currently being obtained
in accordance with the
requirements of ODCM
Control 1.3.1.

------------------Note--------------------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.
--------------------------------------------B.1
If samples are available.
add new location(s) to the
radiological environmental
monitoring program given in
ODCM Section 9.0.
AND

Identify the new location(s)
in the Annual Radioactive
Effluent Release Report
pursuant to ODCM Section
5.2.

NONCONFORMANCE

CONTINGENCY MEASURES
B.2

Pursuant to ODCM Section
5.2 and 5.3, submit in
Annual Radioactive Effluent
Release Report
documentation for a change
in the ODCM including a
revised figure(s) and
table(s) for the ODCM
reflecting the new
location(s) with the
information supporting the
change in sampling
locations.

RESTORATION TIME
Next submittal of
Annual Radioactive
Effluent Release
Report.

VERIFICATION REQUIREMENTS
VR
2.3.2

VERIFICATION
The Land Use Census shall be conducted during the
growing season using that information that will provide
the best results, such as by a door-to-door survey, mail
survey, telephone survey, aerial survey, or by
consulting local agricultural authorities. The results of
the Land Use Census shall be included in the Annual
Radiological Environmental Operating Report pursuant
to ODCM Administrative Control 5.1.

FREQUENCY
12 months

RADIOLOGICAL ENVIRONMENTAL MONITORING

1.3.2 LAND USE CENSUS
BASES
This Control 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 that census.
The best survey information from the door-to-door, aerial, or consulting with local agricultural
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 ft2 provides assurance that
significant exposure pathways via leafy vegetables will be identified and monitored since a garden of
this size is the minimum required to provide the quantity (26 kg/yr) of leafy vegetables 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/m2

9.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM
9.1 MONITORING PROGRAM
An environmental radiological monitoring program shall be conducted in accordance with ODCM Control 1.3.1.
The monitoring program 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 environmental radiological monitoring program shall consist of monitoring stations from which
samples of air particulates and atmospheric radioiodine 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.
9.2 DETECTION CAPABILITIES
Analytical techniques shall be such that the detection capabilities listed in Table 2.3-3 are achieved.
9.3 LAND USE CENSUS
A land use survey shall be conducted in accordance with 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 (or the EPA program code designation
may be provided).
If analyses are not performed as required, corrective actions taken to prevent a recurrence shall be reported in
the Annual Radiological Environmental Operating Report.
