- O C/ 2.0 RADIOLOGICAL ENVIRONMENTAL MONITORING 2.1 Program Overview 2.1.1 Purpose No significant or unexpected radionuclide concentrations of plant origin am expected because each normal effluent pathway at PBNP is monitored at or before the release point. However, the Radiological Environmental Monitoring Program is conducted to verify that plant operations produce no significant radiological impact on the environment and to demonstrate compliance with applicable standards.
2.1.2 Samples Samples for the Radiological Environmental Monitoring Pmgram am obtained from the aquatic, terrestrial and atmospheric environment. The sample types represent key indicators or critical pathways identified by applying sound radiological principles to the PBNP environment.
2.1.3 Monitoring sensitivity The effectiveness of the Radiological Environmental Monitoring Program )
in fulfilling its purpose depends upon the ability to accurately determine I the nature and origins of fluctuations in low levels of environmental l radioactivity. This requires a high degree of sensitivity so that it is possible to correctly discriminate between fluctuations in background radiation levels and levels of radioactivity that may be attributable to the operation of PBNP. Therefore, personnel actively panicipating in the monitoring program should make every effon to minimize the possibility of contaminating environmental samples and to obtain samples of the !
appropriate size.
2.1.4 Technical Specifications ;
l A copy of the PBNP Technical Specifications applicable to the Radiological Environmental Monitoring Program is located in Appendix A of this manual. These specifications are pan of the Radiological Effluent j Technical Specifications (RErS). l A

2.2.1 Contamination avoidance )
Contamination prevents the a: curate quantification of environmental l radioactivity and the correct differentiation between fluctuating background I radioactivity and levels of radioactivity attributable to the operation of l PBNP. Therefore, it is necessary that all personnel associated with I collecting and handling radiological environmental samples take the i appropriate precautions to minimize the possibility of contaminating the i samples. Some of the precautions that should be taken and which will help to minimize contamination' are listed below:
- a. Equipment which has been on the controlled side, even if mieased l clean, should not be used in conjunction with radiological j environmental monitoring; ;
- b. Store sampling equipment in radiologically clean areas only; 1
- c. Store radiological environmental samples only in radiologically clean areas when samples cannot be shipped to the contractor on the same l day they are collected;
- d. Treat each sample as a possible source of contamination for other samples so as to minimize the possibility of cross-contamination;
- e. Radiological environmental monitoring equipment should be repaired in clean-side shops;
- f. Contamination avoidance for environmental TLDs is covemd in Section 2.4.2; and
- g. Do not enter the controlled zone prior to leaving to collect environmental samples.
2.2.2 Sample size Sample size affects the sensitivity achievable in quantifying low levels of
' environmental radioactivity. Therefore, sampling personnel must attempt to attain the quantities of sample specified in Table 2-1. When a range is given, every effort should be made to obtain a quantity at the upper part of the range.

3i e' POINT BEACH NUCLEAR PLANT l NNSR Revision 10 October 19,1994 t ENVIRONMENTAL MANUAL (q) 7 2.2.3 lower limit of detection 1
The sensitivity required for a specific analysis of an environmental sample is defined in terms of the lower limit of detection (LLD). The LLD is the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with a 95%
probability and have only a 5% probability of falsely concluding that a blank observation repmsents a real signal. Mathematically, the LLD is defined by the formula
, 4.66 S.
E x V x 2.22 x Y x EXP(-laT)
Where LLD =
the a priori lower limit of detection in picocuries per unit volume or mass, as applicable; S3 =
the standard deviation of the background counting rate or the counting rate of a blank sample, as appropriate, in counts per
/N minutes; E =
counting efficiency in counts per disintegration; V =
sample size in units of volume or mass, as applicable; 2.22 =
number of disintegrations per minute per picoeurie; Y =
the fractional chemical yield as applicable; A =
the radioactive decay constant for the particular radionuclide; and AT =
the elapsed time between sample collection, or the end of the collection period, and the time of counting.
Typical values of E, V, Y, and AT are used to calculate the LLD. As
- defined, the LLD is an a priori limit representing the capability of a measuring system and not an a costeriori limit for a particular measurement.

A The required analysis for each environmental sample and the highest ;
acceptable LLD associated with each analysis are listed in Table 2-2.
c Whenever LLD values lower than those specified in Table' 2-2 are ,
reasonably achievable, the analytical contractor for the radiological
~
environmental samples will do so. When the LLDs listed in Table 2-2 are not achieved, a description of the factors contributing to the higher LLD shall be reported in the next PBNP Semiannual Monitoring Report. -,
2.2.4 Notification levels i
The Notification Level (NL) is that measured quantity of radioactivity in an environmental sample which, when exceeded, requires a notification of such an occurrence be made to the appropriate party. Regulatory and administrative notification levels are listed in Table 2-2.
- a. Regulatory notification levels l
The regulatory. notification levels listed in Table 2-2 represent the concentration levels at which NRC notification is required by PBNP Technical Specification requirements. If a measured level of radioactivity in any radiological envimnmental monitoring program O sample exceeds the regulatory notification level listed in Table 2-2, ;
V resampling and/or reanalysis for confirmation shall be completed within 30 days of the detennination of the anomalous result. If the j
i confirmed measured level of radioactivity remains above the notification level, a written report shall be submitted to the NRC. If more than one of the radionuclides listed in Table 2-2 are detected in any environmental medium, a weighted sum calculation shall be performed if the measured concentration of a detected radionuclide is greater than 25% of the notification levels. For those radionuclides
- with LLDs in excess of 25% of the notification level, a weighted sum {
calculation needs to be performed only if the reported value exceeds j the LLD. Radionuclide concentration levels, called Weighted Sum Action Levels, which trigger a weighted sum calculation are listed in Table 2-2. ,

- ) Revision 10 October 19, 1994 k_,[ The weighted sum is calculated as follows:
concentration (1) . concentration (2) + . . . = weighted sum notification level (1) notification level (2)
If the calculated weighted sum is equal to or greater than 1, resampling and/or manalysis for confirmation shall be completed within 30 days of l the determination of the anomalous result. If the confirmed calculated weighted sum mmains equal to or greater than 1, a written rejon shall )
be submitted to the NRC. This calculation requirement and report is not required if the measured level of radioactivity was not the result of plant efnuents.
- b. Administrative notification levels ,
l The IRSS administrative notification levels are the concentration levels l at which the contracted analytical laboratory promptly notifies the i I cognizant IRSS engineer by phone, followed by a formal written j communication. The IRSS administrative notification levels are set '
lower than the NRC regulatory notification levels and lower than, or O equal to, the weighted sum action levels so that the natum and origin
) of the incmased level of envimamental radioactivity may be expeditiously ascenained and corrective actions taken if required.
2.2.5 Sampling locations j a
A list of sampling locations and the cormsponding location codes appear in Table 2-3. The locations also are shown in Figums 2-la and 2-lb. It is conceivable that samples may become unavailable fmm specified sample locations. If this were to occur, new locations for obtaining replacement samples shall be identified and added to the Radiological Environmental Monitoring Program. If milk or vegetation samples become unavailable
, from the speciGed sampling locations, new sampling locations will be identified within 30 days. The specific locations whem samples were unavailable may be deleted from the monitoring program. A formal, written reason for the new site and its location shall be transmitted to the l cognizant IRSS engineer who will make the appmpdate changes to the Environmental Manual. Any significant changes in existing sampling .
location and the criteria for the change shall be reported in the Semiannual Monitoring Report for the period in which the change occurred.
Additional sampling locations may be designated if deemed necessary by l cognizant company personnel. Figures and tables in this manual shall be l revised to reflect the changes.

(T )- 2.2.6 Sampling media and frequency The sampling fmquency for the env.ironmental media required by PBNP Technical Specifications is found in Table 2-4. In addition to samples required by Technical Specifications, the Radiological Environmental Monitoring Program also includes the sampling of soil and shomline sediment. To ensum that all samples are obtained at the appropriate times, two different checklists are used. A yearly checklist provides a month-by-month indication of all samples, except air, to be obtained at each sampling location (PBF-4121). This checklist also identifies the schedule for the annual milk survey and pmvides space for recording the date the samples were shipped offsite for analysis. In addition, a sepamte checklist is provided for each sampling location to identify all samples, including weekly air samples, to be obtained and the collection date (PBF-4075 series). Because the weekly air samples mquire additional information, a separate checklist is used for each individual air sampling location as shown in PBF-4078. 1 It is recognized that on occasions samples will be lost or that samples cannot be collected at the specified frequency because of hazardous conditions, seasonable unavailability, automatic sampling equipment
(
\
malfunctions and other legitimate reasons. Reasonable efforts will be made to recover lost or missed samples if warranted and appropriate. If samples are not obtained at the indicated frequency or location, the reasons or explanations for deviations from the sampling frequency specified in Table 2-4 shall be logged at PBNP and shall be conveyed formally in !
l writing to the cognizant IRSS engineer using the appropriate form !
(Figum 2-2). The cognizant engineer will evaluate the sampling problem i to determine whether it constitutes a reportable deviation from the !
Technical Specifications in Table 2-4. If it does, a description of the reasons for not conducting the sampling as specified and, when appropriate, plans for preventing a recurmnce, shall be identified in the l next Semiannual Monitoring Repon by the cognizant IRSS engineer.
2.2.7 Sample labeling All samples must be properly labeled to ensure that the necessary information is conveyed to the analytical contractor and that the results am associated with the correct geographical location. Each label (PBF-4026) i must contain the following:
{
- a. Sample type;
/N Ul b. Sample location fmm Table 2-3; i
- c. Date and time (as appropriate) collected; 1

- e. Analyses for routine samples are indicated as "per contract." For I special samples, the Health Physics manager or the Cognizant Specialist - Nuclear Health Physics will designate the analyses requimd; and I
- f. Name of person collecting the sample.
A permanent or indelible ink type felt-tip marker shall be used.
A separate sample label is needed for each sample type and location. l 12bels am securely attached to each sample container. In addition to sample labels, other identifying markings may be placed on sample containers as appropriate. 1 2.2.8 Sample shipping All environmental samples are shipped to a contractor for analysis. The i
/' samples shall be packaged and shipped in such a way as to minimize the !
possibility of cross-contamination, loss, spoilage and leakage. Each sample shipment shall have a typed cover letter and, when appropriate, a contractor data collection sheet. Included in the letter shall be the same information required for the sample labels as well as the specific analyses required. The original cover letter and data collection sheet shall be sent to the contractor under separate cover; one copy of each is to be used as a packing list and a copy of each shall be kept in the appropriate PBNP file.
2.2.9 Sample analyses and frequency The PBNP Radiological Environmental Monitoring Program samples shall be analyzed for designated parameters at the frequency listed in Table 2-5.

The analyses are performed by a contractor. The current contractor is:
l Teledyne Brown Engineering Environmental Services 700 Landwehr Road Nonhbrook, IL 60062-4517 (708)S64-0700 This laboratory, former named Hazleton Environmental Sciences Corporation, performs the analyses in such a manner as to attain the desired LLDs. The contracted laboratory participates in the inter-laboratory comparison crosscheck program conducted by the U.S.
Environmental Protection Agency, Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support I2boratory, Las Vegas, Nevada.
l The contractor is responsible for providing prompt notification to IRSS l regarding any samples found to exceed the IRSS administrative notification levels as identified in Table 2-2.
2.3 Assistance to the State of Wisconsin As a courtesy and convenience, PBNP personnel obtain cenain environmental samples for the Section of Radiation Protection, Depanment of Health and Social Services of the State of Wisconsin as listed in Table 2-6. A checklist is used as shown in PBF-4075 series. In addition, a State of Wisconsin air sampling data sheet is submitted with each sample obtained at Wisconsin air sampling locations serviced by PBNP personnel.
State of Wisconsin precipitation samples collected twice a month (or as available) require a state sample tag to be placed in a box with the quan cubitainer. State supplied labels for air particulate filters require start and stop time, date and beginning and ending volume. Fish sent to the state identify only the quaner and the year using a PBNP label (PBF-4026). The monthly lake water composite is picked up by state personnel and therefore requires only that the date and location be written on the box for the cubitainer. The state provides a sample tag for the quanerly lake water sample.

Radiation Protection laboratory Room 111 State laboratory of Hygiene 465 Henry Mall Madison, Wisconsin 53706 2.4 Specification of Sampline Pmcedures General radiological environmental sampling procedures follow the directives presented in Sections 2.1 and 2.2. Specific information for handling individual sample types follow.
2.4.1 Vegetation Vegetation samples consist of green, growing grasses and weeds and are l obtained three times per year, as available, from specified locations. New l growth, not dead vegetation, should be used because these samples are indicators of recent atmospheric deposition. Use a scissors or other sharp -l
,P cutting tool to cut the grasses and weeds off as close to the ground as l possible. Do not include plant roots and take care not to contaminate the i sample with soil. Total sample collected should exceed 500 grams and l ideally should be 1000 grams Place entire sample in a plastic bag, tape the bag shut, and label the bag as described in Section 2.2.7.'
2.4.2 Thermoluminescent dosimeters (TLDs)
TLDs capable of multiple, independent measurements of the same exposure are posted at the twenty-seven (27) locations specified in Table 2-4 and are changed quarterly. The utmost care in handling is required to minimize unnecessary exposure during transit, storage and posting because the TLDs begin recording all radiation from the moment they are annealed (heated to rezero) at the contractor's laboratory. l Packages of TLDs in transit should be marked "DO NOT X-RAY."
A transpostation control (E-TC) shall accompany the new batch in transit from the contractor's laboratory to the plant. The control shall accompany the batch during brief storage and subsequent posting. The same control shall accompany the "old" or exposed batch on its way back to the contractor. Therefore, each control represents the sum of approximately half the in-transit exposure of the two batches. This control system is able O to identify any unusual in-transit exposure.

,p Both particulate filters and charcoal canridges are employed at each sampling location. Paniculate filters are analyzed for gross beta activity after waiting for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to allow for the decay of shon-lived radon and thoron daughter products. The contractor makes quarterly composites of the weekly paniculate samples for gamma isotopic analyses.
A regulated pump (Eberline Model RAS-1 or equivalent) is used at each air sampling location. Because of the automatic flow regulation, rotameter readings at the beginning and ending of the sampling period should be nearly identical. Substantial differences in readings usually require some investigation to determine the cause. The rotameters attached to the pumps are calibrated in liters per minute. When new filters are installed, flow rate should be about 28-301pm. Flow rates less than 261pm or gmater than 321pm require that the pump regulator be readjusted. The correct flow rate is determined by multiplying the rotameter reading by the correction factor indicated on the calibration sticker affixed to the rotameter.
I Some pumps am equipped with an elapsed time meter which reads in i hours. Form PBF-4078 is used for recording peninent air sampling ,
data for each location. At a noimal filter change, the following j procedure will apply ,
l 1
l 1. Record "date off" and " time off."
- 2. Record rotameter reading for end of period (R2).
I 3. Turn off pump, if necessary, and record hour meter reading or l actual time for end of period (t2)-
l
- 4. Before removing the filter, label the envelope as directed in Section 2.2.7. Also enter any other pertinent information at this time. Always write data on the envelope before the particulate filter is in the envelope.
- 5. Remove particulate filter being careful to handle filter only by edges, place in envelope.
- 6. Remove charcoal cartrioge, place in plastic bag, and label as ;
directed in Section 2.2.7.
'p 7. Install new charcoal cartridge and paniculate filter being sure to I check the charcoal cartridge for breaks and the paniculate filter for l holes in the filter surface. Discard unacceptable filter media.

Air samples are collected for the State of Wisconsin at three locations, one of which is co-located with a PBNP air sampling site. They are handled in a manner similar to PBNP samples except that no charcoal cartridges are involved. However, state samplers are equipped with volume integrating meters. Therefore, clock time must be recorded in addition to the ending and beginning volumes. Label and fonvard samples to the State.
- b. Air sampling system description The air monitoring equipment for the PBNP air sampling program consists of a Regulated Rate Control System. The Regulated Rate Control System is used at PBNP because of its simplicity and ,
reliability. It is designed to minimize both calibration difficulties and !
the potential for leaks. The regulated rate control system includes a ;
l pump, a flow regulator, the appropriate filter holders and a minimum l
l of tubing. Also, it may include an elapsed time meter. In this system, l the total volume sampled can be calculated simply and accurately from ;
pl the elapsed time ar.d the flow rate which is kept constant by the
{
Q regulator regardless of filter loading. j l Page 17 of 35 INFORMATION USE I

() The air samplers are Eberline Model RAS-1 (or equivalent) and have built-in rotameters which read in liters per minute. The systems also l include an Eberline WPH-1 (or equivalent) weatherproof housing and I an iodine cartridge holder and mounting kit and may include an electric
, I hour meter. Currently, all metallic and rigid plastic tubing and rigid fittings are used in lieu of tygon tubing and quick disconnects. Glass fiber,47 mm diameter, particulate filters capable of collecting 95% of 1 micron diameter panicles and iodine impregnated charcoal cartridges (Scott or equivalent) constitute the filter media.
- c. Calibration Calibrate the pump rotameter at initial installation and at yearly intervals thereafter by connecting a laboratory-quality reference flow meter with NBS traceable calibration to the filter face with the paniculate filter and charco ? canridge in position. Upon completion, a calibration sticker indicating the correction factor is affixed to, or near, the built-in rutameter. The results air recorded on Form PBF-4020. ,
- d. Inspection and maintenance A :
1
- k. Initially, and at quanerly intervals, not to exceed 16 weeks, thereafter,-
the assembled system should be checked for leaks by attaching the reference flow meter across the face of the filter holder with the filters ,
in position. Irakage in this configuration is indicated by'a higher reading on the built-in rotameter than on the reference flow meter. l Because leakage is indicated by disagreement between the two flow measuring devices, remember to apply the calibration correction factor to the built-in rotameter reading. I.cak tests are to be recorded on l Form PBF-4020. Weekly gross leak checks and quanerly leak tests shall be accomplished as indicated in the appropriate PBNP procedure.
{
For normal operation, the regulators should be adjusted to maintam a j true flow rate of 28-30 liters per minute. Adjustments are made by j turning the screw marked FLOW ADJUST located on the side of the '
regulator body: counterclockwise increases flow, clockwise decreases flow. Flow rates should be observed at all filter changes. Flow mtes
- less than 261pm or more than 321pm require readjustment of the !
regulator. Particular attention should be paid to flow rate readings 1 with the "old," loaded filter and with new, unused filters in position. l Because of the regulator, the difference in flow should be barely perceptible, perhaps no more than one Ipm. Significant differences in g flow rates require funher investigation to detennine the cause.

/m l Preventive maintenance shall be performed as indicated in the
'I appropriate PBNP procedure on all environmental air samplers and the l results recorded on Form PBF-4020.
- e. Pump repair and replacement The pumps can operate for long periods of time with minimal or no maintenance. The vane assembly of the pump is most susceptible to failure, indicated by excessive noise or inability to maintain suf6cient flow across loaded filters. At least one standby pump should be available for temporary service during the repair period. In the event of motor failures due to causes other than defective connections, complete replacement of the unit may be necessary. All pump repairs should be done in a clean-side shop with clean tools.
2.4.6 Milk Because of iodine decay and protein binding of iodine in aging milk samples, speed is imperative in processing and samples must be kept cool to avoid degradation and spoilage of the samples. Milk samples are obtained monthly in conjunction with the State of Wisconsin Milk
[~'N Sampling Program from three individual dairy farmers located nonh,
() south, and west of the site. Because two of the three sites are co-located, the PBNP pickup is coonfinated to coincide with the State arranged schedule. The pickup usually will be the Grst Wednesday of the month.
The following sequence should be followed: .
- a. After verifying the State milk pickup date with the Manitowoc Public Health Department (Mr. Alan Troullier, phone number 683-4454),
notify Mr. Leon Strutz (755-2060) of the pickup date. This must be done because the Strutz farm (PBNP sampling location E-21) is not a State of Wisconsin sampling site.
- b. Because the milk must be kept cool, but not frozen, fill enpugh cubitainers with water and freeze to be able to put one in each shipping container. Fill the cubitainers with water and freeze the day preceding the pickup.
- c. The milk from the Strutz farm (E-21) must be picked up before 0900 because that is the time the Strutz milk is shipped. A late arrival may mean a missed sample. Milk from sites E-Il and E-19 rnay be picked up any time after the Strutz pickup.

.s Revision 10 October 19,1994 i' ENVIRONMENTAL MANUAL p
CI d. Identify yourself and the nature of your business at each milk pickup site. Collect two one-gallon samples from each site, using a funnel if necesrary. Place each gallon in a one-gallon box liner for shipment.
If shipment cannot occur on the collection day, store the milk in a clean-side refrigerator overnight. DO NOT FREEZE.
- e. Complete a PBNP sample tag according to Section 2.2.7 for each gallon sample and place in the box with the sample. Do not seal the box. Place the samples in insulated c'ontainers and turn them over to Ready Stores personnel for shipment. Make sure that the cover letter and, as appropriate, the contractor data collection sheets are sent according to Section 2.2.8 of this manual.
2.4.7 Algae Filamentous algae are collected from pilings or rocks three times per year, as available, from two locations. The long, grassy, dark green algae can normally be cut with scissors. The shorter, light green algae normally must be semped from rocks or pilings. When scraping algae, be careful not to include pieces of rock in the sample. The sample can be lightly rinsed in the same medium in which it is growing. This rinse will help rid Q the sample of pieces of rock and gravel that may have been inadvertently Q collected with the sample. Because rocks and sediment contain naturally occurring radioactive materials, their inclusion may give false sample results. Collect between 100 and 1000 gm of algae. A sample greater than 500 gm is preferred. Place the algae in a 1000 ml cubitainer and label the container as director in Section 2.2.7. The algae must be kept cool to prevent spoilage.
2.4.8 Fish Fish are obtained three times per year (March, August and December) as available either from the traveling screens as washed into the fish basket or by other methods as required. For any given sampling period, three fish, or a sufficient number to yield at least 1000 gm of fillets, should be provided.
Place fish in plastic bags and tape and/or tie tightly closed. Fish are stored briefly in~a radiologically clean freezer. It may be desirable in warm weather to coordinate milk and fish sampling, thereby allowing simultaneous shipment in insulated containers. Pack fish samples with ice if needed. I.abel bags as directed in Section 2.2.7, being sure to indicate fish species when possible. Following packaging of fish, remove and
( discard any fish left in the freezer. This avoids sending fish that are not representative of the sampling period.
j Page 20 of 35 INFORMATION USE
POINT BEACH NUCLEAR PLANT l NNSR a Revision 10 October 19, 1994 ENVIRONMENTAL MANUAL n
Fish are obtained four times per year (March, June, September and December) for the State of Wisconsin. Fish sampling for the State is performed in the same manner as that for the plant. Approximately four l fish should be sent to the state at each sampling period.
l l In March and December split samples am sent to Teledyne and the State of Wisconsin. Each fish is bisected with one half going to Teledyne and the other half to the State. .
2.4.9 Soil Soil integrates atmospheric deposition and acts as a reservoir for long-lived radionuclides. Although soil sampling is a poor technique for assessing small incremental releases and for monitoring routir.c releases, it does provide a means of monitoring long-term trends in atmospheric deposition in the vicinity of PBNP. Therefore, soil samples are obtained two times per year from specified locations.
Clear the vegetation from a 6" x 6" area, being careful to leave the top layer of soil relatively intact. Remove root bound soil by shaking the soil onto the cleared area or into the sample container before discarding the f( roots. When necessary, it is preferable to leave some roots in the soil rather than to lose the top layer of soil.
Remove the soil to a depth of three inches. If necessary, e.xpand the area, instead of digging deeper, to obtain the required amount of sample. If an l area larger than 6" x 6" is used, notify the cognizant IRSS Engineer of the area used. The minimum acceptable quantity is 500 grams. Place the entire soil sample in a 1000 mi plastic bag and seal the bag with tape.
Label the sample as directed in Section 2.2.7.
This procedure assumes that the samples are obtained fmm undisturbed land; land that has not been plowed within approximately the last 25 years. ;
If the land has been plowed, the soil should be sampled to the plow depth which typically is eight inches. Place the soil in a clean bucket or appropriate size plastic bag, homogenize the soil and place 1000 grams of the well mixed soil sample in a plastic bag and label as described above.

C1 2.4.10 Shoreline Sediment Shoreline sediment consisting of sand and smaller gmin size material is sampled two times per year fmm specified locations. The 1000 gram sample is collected, from beach areas near the water ridge. At each location collect representative samples of sediment types mughly in proportion to their occurrence. For example, at E-06 avoid collecting a sample which consists exclusively of the dark-brown to black sedime'nts which occur in layers up to several inches thick. Package the sample in a 1000 ml cubitainer and label .as described in Section 2.2.7.
2.5 Milk Survey In accordance with PBNP Technical Specifications, the milk sampling pmgram is reviewed annually, including a visual verification of animal grazing in the vicinity of the site boundary, to ensure that sampling locations remain as conservative as practicable. The verification is conducted each summer by cognizant PBNP personnel. Because it is already assumed that milk animals may graze up to the site boundary, it is only necessary to verify that these animals have not moved onto the site. No animal census is required. Upon completion of the visual check, PBNP l personnel will notify IRSS in writing. To ensure performance of the annual O verification, " milk review" is identified on the sampling checklist, PBF-4121.

15.7.7 OPERATIONAL ENVIRONMENTAL MONITORING PROGRAM Applicability This section applies to operational environmental radioactivity monitoring and sampling.
1 Objective To verify that plant operations have no significant radiological effects on the environment.
Specifications A. Environmental Monitoring Program
- 1. Environmental monitoring samples shall be taken at locations d specified in the PBNP Environmental Manual according to the ;
sampling and collection frequencies given in Table 15.7.7-1. I
- 2. Deviations from the required sampling schedule as specified in j Table 15.7.7-1, are permitted if hazardous conditions, seasonal ,
unavailability, automatic sampling equipment malfunctions, and other legitimate reasons make the sample unobtainable. If the radiological environmental monitoring program is not.being con- -
ducted as specified in Table 15.7.7-1, a description of the reasons for not conducting the program and the plans for preventing a J recurrence will be submitted with the next Semiannual Monitoring Report.
- 3. If milk or vegetation samples become unavailable from'one or more of the sample locations specified in the PBNP Environmental Manual, l identify locations for obtaining replacement samples and add them to the radiological environmental monitoring program within 30 days. The specific locations from which samples were unavail-able may then be deleted from the monitoring program. The cause of the unavailability of samples and replacement samples shall be

C identified in the next Semiannual Monitoring Report. Figures and tables in the Environmental Manual are to be revised reflecting the new sample locations.
B. Detection Capabilities
- 1. Environmental samples shall be analyzed as specified in Table 15.7.7-2.
- 2. The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs).
- 3. If circumstances render the stated LLDs in Table 15.7.7-2 unachiev-able, the contributing factors shall be identified and described in next Semiannual Monitoring Report.
C. Notification Levels
- 1. If a measured level of radioactivity in any environmental medium exceeds the notification level listed in Table 15.7.7-3, resampling and/or reanalysis for confirmation shall be completed within 30 days of the determination of the anomalous result. If the con- l firmed measured level of radioactivity remains above the notifi-cation level, a written report shall be submitted to the NRC in accordance with Section 15.7.8.4.B within thirty days of the confirmation. This report is not required if the measured level of radioactivity was not the result of plant effluents.
- 2. If more than one of the radionuclides listed in Table 15.7.7-3 are detected in any environmental medium, a weighted sum calcula-tion shall be performed if the measured concentration of a detec-ted radionuclide is greater than 25% of the notification levels.
For those radionuclides with LLDs in excess of 25% of the notifi-cation level, a weighted sum calculation need only be performed if the reported value exceeds the LLD. The weighted sum is calculated as follows:
concentration (1) , concentration (2) ,,,, _ weighted notification level (1) notification level (2) sum If the calculated weighted sum is' equal to or greater than 1, resampling and/or reanalysis for confirmation shall be completed within 30 days of the determination of the anomalous result.

(1 the confirmed calculated weighted sua remains equal to or. greater
): than 1, a written report shall be submitted to the NRC in accor-dance with Section 15.7.8.4.8 within thirty (30) days of the con-firmation. This calculation requirement and report is not required s if the measured level of radioactivity was not the result of plant effluents. -
- 3. All detected radionuclides shall be reported in the Semiannual Monitoring Reports. Naturally occurring nuclides such as Be-7, K-40,.and the U-238 and Th-232 decay series radionuclides shall l not be included in this requirement.
D. Land Use Census '
i 1.
The milk sampling program shall be reviewed annually, including a visual verification of animals grazing in the vicinity of the site boundary, to ensure that sampling locations remain as con-servative as practicable.
E. Interlaboratory Comparison Program
- 1. The environmental sampling analyses shall be performed by a laboratory participating in an Interlaboratory Comparison O 2.
Program. -
If the analytical laboratory is not participating in the Inter-laboratory Comparison Program, a description of the corrective I actions to be taken to preclude a recurrence shall be submitted in the Semiannual Monitoring Report. '
Basis The operational radiological environmental monitoring program as outlined in l Table 15.7.7-1 provides sufficient sample types and locations to detect and to evaluate changes in environmental radioactivity. Although radioactivity I in plant effluents is continuously monitored and releases are well below levels which are considered safe upper limits, radiological environmental monitoring is a conservative measure undertaken to determine whether the operation of the Point Beach Nuclear Plant produces any significant radio- ;
logical change in the surrounding environment.
q Radioactivity is released in liquid and gaseous effluents. Air particulate M samples and thermoluminescent dosimeters placed at various locations provide, means of detecting changes in environmental radioactivity as a result of plant releases to the atmosphere. l Unit 1 Amendment 97 15.7.7-3 - October 10,.1985 Unit 2 Amendment 101 _ _
. . a 9
The land in the area of Point Beach Nuclear Plant is used primarily for farming and dairy operations. Therefore, radiological environmental sampl-ing of vegetation is conducted to detect changes in radiological conditions at the base of the food chain. Sampling of area produced milk is carried out because dairy farming is a major industry in the area.
Water, periphyton, and fish are analyzed to monitor radionuclide levels in Lake Michigan in the vicinity of PBNP. Periphyton, attached algae, concen-trate radionuclides from the surrounding lake water. Therefore, algae samples, along with lakewater samples, provide a means of detecting changes which may have a potential impact on the radionuclide concentrations in Lake Michigan fish. Because of the migratory behavior of fish, fish sampling is of minimal value for determining radiological impact specifically related to the operation of'the Point Beach Nuclear Plant. However, fish sampling is carried out as a conservative measure with emphasis on species which are of intermediate trophic level and which exhibit minimal migration in order to monitor the status of radioactivity in fish.
l I Vegetation, algae, and fish sampling frequencies are qualified on an "as q
available" basis recognizing that certain biological samples may occasionally be unavailable due to environmental conditions.
