I I. INTRODUCTION ine Radiological E nvironment al Monitorina Proaram for the Comanene l Peak Steam Electric Station was conducted under contract with T U Electric, inis report covers the period f rom January 1, 1989 through December H, f 1969 and summarizes the results of measurements and analyses of data obtaina from samples collected durina this inserval. I Site and Station Description A. Comanchet Peak Steam Electric Station consists of two PWR units, each desi ned to operate at a power level of about 1150 megawatts (electrical). The station is located on Sauaw Creek Reservoir in Somervell County about 40 miles southwest of Fort Worth, Texas. Unit I received a low power cperating license february 6, 1990. Initial criticality of Unit 1 is espected in April, 1990. l B. Objectives and Overview of the CPSES Monitoring Program United States Nuclear Reguletory Comission (USNRC) regulations require th at nuclear power plants be designed, constructed, and operated to keep i levels of radioactive material in effluents to unrestricted areas as low as reasonably achievable (ALARA) (10 CFR 50.34). 70 assure that these criteria are met, e&ch license authorizing reactor operation includes technical specifications (10 CFR 50.36a) governino the release of radioactive effluents. I In-plant monitoring will be used to assure that these predetermined l release limits are not exceeded. and undefined processes wnich might allow undue accumulation of radioactivity However, as a precaution against unexpected in any sector of man's environment, a program for monitoring the plant environs is also included. lI j

I I I Samplinq locations were selected on the basis of local ecolocy, meter-olooy, physical characteristics of the recion, and demoaraphic and land use features of the site vicinity. The preoperational program was designed on the basis of the USNRC Branch Technical Position on radiolootcal environ-mental monitoring issued by the Radiological Assessment Branch, Revision 1 (November 1979)(1), the CPSES Technical Specifications, and the CPSES Of fsite Dose Calculation Manual (ODCM). In 1989 the radiological monitoring program iricluded the measurement of ambient gamma radiation by thermoluminescent dosimetry; the determination of gamma emitters in vegetation, sediment and fish; the determination of air-borne cross beta, gamma emitters, and iodine-131; the measurement of tritium and gamma emitters in surf ace water; the measurement of gross beta, tritium and gamma emitters in ground water; the measurement of gross beta, tritium, 1-131 and gamma emitters in drinking water; and the determination of gamma emitters and 1-131 in milk. i Samples were collected by CPSES Environmental Personnel. Sample ana-lyses were performed by Teledyne isotopes under contract. l I I 3
1 I I I o The regulations governing the quantities of radioactivity in reactor effluents allow nuclear power plants to contribute, at most, only a few percent increase above normal background radioactivity. Background levels at any one location are not constant but vary with time as they are influenced by external events such as cosmic ray bombardment, weapons test f allout, and seasonal variations. These levels also can vary spatially within relatively short distances reflecting variations in geological composition. Because of these spatial and temporal variations, the radiological surveys of the plant environs are divided into preoperational and operational phases. The pre-operational phase of the program of sampling and measuring radioactivity in various media permits a general characterization of the radiation levels and concentrations prevailing prior to plant operation along with an indica-tion of the degree of natural variation to be expected. The operational phase of the program obtains data which, when considered along with the data obtained in the preoperational phase, assist in the evaluation of the radio-logical impact of plant operation. l Implementation of the preoperational monitoring program fulfills the following objectives:
- 1. Evaluation of procedures, equipment and techniques.
- 2. Identification of potentially important pathways to be monitored after the plant is in operation.
I 3. Measurement of background levels and their variations along poten-tially important pathways in the area surrounding the plant. 4 Provision of baseline data for statistical comparison with future operational analytical results. I I 4

!!. PROGRAM OESCRIPTION Seventy four (74) locations aitnin a radius of 15 miles from the CPSES site were included in the monitoring prooram for 1989. The number and I
location of monitoring ooints were oetermined by considering the locations where the highest of f. site environment al Concentrations have been preciCted i from plant effluent source terms, site hydrology, and site meterological l l conditions. Cther factors considereo were aDolicable regulations, population distribution, ease of access to sampling stations, availability of s ampl es at desired locations, security and future program integrity. The preoperational environmental radiological program for Comanche Peak is summarized in Table 1. Figures 1 and 2 show the locations of the various s ampling points. l 111. SAMPLING METHODS AND PROCEDURES To derive meaningf ul and useful data from the Radiological Environmentc' Monitoring Program, sampling methods and procedures are required which will provide samples representative of potential pathways of the area. During the preoperational phase of the program, samples are collected and analyzed not only to obtain background radiological levels, but at the same time to acquire experience with the sampling methodology and procedural format dictated by site specific requirements. A. Direct Radiation Thermoluminescent dosimeters (TL0s) were used to determine tne direct (ambient) radiation levels at monitoring points. Sampling locations were chosen according to the criteria given in the USNRC Branch Technical Position on Radiological Monitoring (Revision 1, November 1979),(1) The area arouno the station was divided into 16 radial sectors of 221/2 degrees each. TL0s were placed in 011 sectors. TL0s were located in two rings around the station. An inner ring was located at the site boundary and an outer ring 6
I
.as located at a distance of 4 to 6 miles from the station. Eleven aadi.
tional TL0s were located at points of special interest, including two control l oc ations . For routina TLD measurements, two cosimeters of CaSO4: Dy in teflon cards were deployed at each selected locatian. One set of dosimeters nas exchanced on a quarterly basis and the second set wa', exenanced on an annual basis. Additional sets of dosimeters were snipped with each excnange cycle to serve as in transit controls. For routine excnances, TLDs were shippeo by Federal Express. Individual dosimeters were calibrated by exposure to an accurately known radiation field f rom a calibrated Cs-137 source. B. Air Particulates/ Air lodine Air particulate and air iodine samples were collected f rom the 8 locations described in Table 1. tio samples were collected from St at ions N-2.2, E-0.5, SE 3.85. W-2 and NNW-4.6, which had been included in the sampling program in previous years. These locations were deleted as a part of the transition to the operational monitoring program reouired by the CPSES ODCM. Each air particulate sample was collected by dr awing air througn a 47-millimeter di ameter glass-fiber filter. Air iodine was collected by drawing air through a TEDA impregnated charcoal cartridge /(Scott NO 605018-
- 03) which was connected in series behind the filter. The filters ano enar-coal cartridges were collected weekly by CPSES staff, in the laboratory, air particulate filters were analyzed for gross beta activity and were composited quarterly for analysis by gamma spectrometry. Charcoal cartridges were analyzed for iodine-131.
C. Milk Milk samples were collected by CPSES staff monthly except for May through October when samples were collected bimonthly. There were two 1 7
, I { principal milk sampling locations; one inoicator location, SSE 2.2 and one control location, SW-13.5. Upon arrival at the laboratory, the milk samples were promptly analyzed for gamma emitters and for 1-131 by radiochemistry. J. Water Tne CPSES staff collected water f rom 11 locations. Surf ace water was collected at f our locations (N-19.3, ESE-1.4, h-1. 5 a nd NE- 7. 4 ) . Surface-drinting water was collected at two locations (N 9.9 and NNW-C.1). Location h-l.5 provices sampics representative of S uaw Creek Reservoir surface water at a location beyond significant influence of the plant discharge. Location ESE-1.4 provides samples representative of discharges f rom Squaw Creek Reservoir, both down Squaw Cretek and to Lake Granbury via the return line. Location k-7.4 provides samples of Lake Granbury surf ace water down stream of the discharge of the return line from Squaw Creek Reservoir. There are five groundwater locations (SSE 4.6, W 1.2, WSW 0.1, N-1.45 and N-9.8. Samples from these locations were analyzed pursuant to the 00Cl1 drinking water requirements through 04/24/89. Af ter this date, the analysis for drinking water was climinated and the samples were analyzed only for gamma emitters and tritium. This change was made as part of the transition to the operational program described by the 00Cli. 00CM Table 3.1, Note (5) states that groundwater supplies in the site area are not af fected by plant effluents and are sampled only to provide confirmation that groundwater is not af f ected by plant discharges. All samples were shipped back to the laboratory and analyzed by gamma spectrometry and composited by location quarterly for tritium analysis. Drinking water samples were also analyzed monthly for gross beta, gamma isotopic and bi-monthly for iodine -131. E. Fish Eleven fish samples were collected at two locations for the 1989 I e
, I prooram. An area 2.0 miles east northeast of the site in Squaw Creek Reservoir was chosen as the indicator location, and a location at Lake Granbury was chosen as a control locStion, fish sampling was conducted in April and October for Station NNE 8(F2) and April and September for Station ENE 2(F1). Fish were collected by CPSES staff. Available edible species were gutted at the time of collection. Samples were then froren and shipped to the laboratory for analysis. Fish were filleted in the laboratory and the edible portion I analyzed by gamma spectrometry. F. Shoreline Sediment Shoreline sediment samples were collected in February and Augus' ' rom Squaw Creek Reservoir, the indicator location. This is in an area of potential recreational usage, 1.0 mile north-northeast of the station. Samples were also collected from Lake Granbury, the control location, on the same days. Samples were also collected from Lake Granbury downstream of the discharge of the return line from Squaw Creek Reservior on the same dates. CPSES staff collected the sediment samples and thiDped them to the laboratory for analysis by gamma spectrometry. G. Food Products and Broadleaf Vegetation During the period May through December, forty-seven samples were col-lected f rom five sampling locations. Food products were collected f rom a control (13.5 miles southwest) and two indicator stations. A total of ten different types of food products were collected during this Samplino period. Broadleaf vegetation was collected from the control location and two indicator ste', ions near the site boundary, Collection of broadleaf veget a-tion started in May, 1989, as part of the transition to the operational program required by the ODCM. Broadleaf samples consisted primarily of available tree leaves; if tree leaves were unavailable, native grasses and weeds were substituted. I e

SUMMARY
AND DISCUSSION OF 1989 ANALYTICAL RESULTS I Data from the radiological analyses of envi ronment al media collected during the report period are tabulated and discussed below. Tne procedures and specifications followed in the laboratories for these analyses are as required in the Teledyne isotopes Quality Assurance manual, !WL-0032-395 and are detailed in Teledyne isotopes Analytical Procedures manual. Radiological analyses of environmental media characteristically approach and frequently f all below the detection limits of state-of-the-art measure-ment methods.(2) The use of "<" in the data tables symbolizes that the result is less than the lower limit of detection (LLD) as defined in Appendix B. "ND" (Not Detected) is used periodically in the tables presenting gamma analysis results for various media. It primarily appears under the "Others" column, and indicates that no other detectable gamma emitting nuclides were identified. The Teledyne Isotopes analytical methods meet the LLO require-ments addressed in the CPSES Offsite Dose Calculation Manual. I Tables 2 through 21 give the radioanalytical results for individual s ampl es. A statistical summary of the results appears in Table 22. The reported averages are based only on concentrations above the limit of detec-tion. In Table 22, the fraction (f) of the total number of analyses with detectable activity follows in parentheses. Also given in parentheses are the minimum and maximum values of detectable activity during the report period. I 4 11
I I A. Direct Radiation Envi ronmental radiation dose rates determined by thermoluminescent dosimeters (TLDs) are given in Table 2. TLD badges cf four readout areas each were deployed at each location on quarterly and annual cycles. The mean values of four readings (corrected individually for response to a known dose and for in-transit exposure) are reported. A statistical summary of the 1989 data is included in Table 22. For the quarterly analyses the average activity of the control locations was 0.16 mR/ day with a range of 0.12 to 0.18 mR/ day. The average of the indicator locations for the quarterly samples was 0.16 mR/ day with a range of 0.11 to 0.22 mR/ day. For the annual samples: The activity for the control samples was 0.13 mR/ day for each. The indicator locations had an average of 0.13 mR/ day with a range of 0.11 to 0.17 mR/ day. Oakley(3) calculates an ionizing radiation dose equivalent of 82.2 mR/ year for Fort Worth including a terrestrial component of 45.6 mR/ year and an ionizing cosmic ray component of 36.6 mR/ year (excludes neutron compo-nent). Since Oakley's values represent averages covering wide geographical I areas, the measurce ambient radiation average of 58 mR/ year for the immediate locale of CPSES is not inconsistent with Oakley's observations. Significant variations occur between geographical areas as a result of geological com-position and altitude differences. Temporal variations result from changes in cosmic ray intensity, local human activities, and factors such as ground cover and soil moisture. I I 12
I I B. Air Particulates/ Air lodine A total of 411 charcoal cartridges were analyzed for airborne iodine-131 by gamma spectrometry. No iodine-131 was detected at any of the samplina stations. Results of these measurements are presented in Table 3. A total of 410 air particulate filters were collected and analyzed for gross beta activity. For the year of 1989 the average gross beta I activity for the control location was 0.024 pCi/m3 with a range from 0.0097 to 0.051 pct /m3 For the eleven indicator locations the yearly average was 0.024 pC1/m3 with a range f rom 0.0053 co 0.055 pC1/m3 The gross beta analysis data are presented in Table 4 Air filters were composited quarterly and then analyzed by gamma spectrometry. The gamma spectrometry data is presented in Table 5. Cosmogenic beryllium-7 was detected in all 32 samples while potassium-40, a naturally occurring nuclide, was measured in four samples. The average beryllium-7 activity for the control location was 0.071 pCi/m3 with a range of 0.066 to 0.081 pCi/m3 For the indicator locations, the average beryllium-7 activity was 0.072 pCi/m3 with a range of 0.060 to 0.099 pCi/m3 Naturally occurring potassium-40 was not detected at the control I location. The average potassium 40 activity for the indicator locations nas 0.012 pCi/m3 with a range of 0.0093 to 0.015 pC1/m3 C. Milk There were a total of 38 milk samples collected in 1989; 19 from the indicator location and 19 from the control location. All samples were analyzed for iodine-131 by radiochemistry and for other gamma-emitting isotopes by gamma spectrometry. No iodine-131 was found in any of the milk samples. The lower limits of detection can be found in Table 6, 13
l Results of the gamma spectrometry measurements are cresented in Table l
- 7. Naturally occurring potassium 40 was detected in all of the milk samples, i
The average activity for the control location was 1379 pCi/l with a range of 1110 to 1560 pCi/1. For the indicator location the average activity was 1298 pCi/l with a range of 1150 to 1510 pCi/l, Cesium-137 was not detected in any of the samples. I D. Water Ground and drinking water simples were collected from five locations during 1989. Samples were analyzed pursuant to drinking water requirements through 04/24/89. Subsequent samples were analyzed only for gamma isotopic and tritium on a quarterly basis, pursuant to the ODCM requirements for , l groundwater. Thirty samples were analyzed f or gamma emitters by gamma i spectrometry. The gamma spectrometry analyses showed no detectable activity above the LLO for all samples, fif ty samples were also analyzed for iodine-131 with no measurable activity. Quarterly composites for each s ampling l location were analyzed for tritium. No tritium was detected. Twenty-five ground and drinking water samples were analyzed for gross beta; 16 indicator locations had measurable activity with aa average of 7.0 pC1/1 and a range of 1.0 to 10 pC1/l . All five of the control samples had measurable gross beta activity with an average of 3.0 pCi/l and a range of 2.2 to 3.9 pCi/1. Results of these analyses are contained in Table 8, 9, 10 and 11 respec-tively. Surf ace water was sampled from four locations during 1989. Samples from these locations were analyzed pursuant to drinking water requirements through 04/24/89. Subsequent samples were analyzed only for gamma isotopic on a monthly basis and tritium composite on a quarterly basis, per the 00CM requirements for drinking water. Fif ty-two samples were analyzed by gamma spectrometry. No radioactivity was detected above the lower level of l detection. Sixteen samples were analyzed for iodine-131, results were below 14
the lower limit of detection. Sixteen composited surf ace water samples were analyzed for tritium and all were below the lower level of detection. Results are presented in Tables 16, 17 and 18 respectively. Surf ace water-drinkino was collected from two stations. All s amples were analyzed for gamma emitters; results were below the lower lirri t of detection. Thirty samples were analyzed for gross beta activity. The indicator station had an average activity of 16 pCi/l with a range of 13 to 21 pCi/1, The control station had an average activity of 14 oCi/l with a range of 9.0 to 21 pct /l. The quarterly composites for tritium were below the lower limit of detec; ion. lodine-131 analyses by radiochemistry were performed on 54 s amples of surf ace water-drinking. There was no measurable activity. Results of these analyses are contained in Tables 12 15. E. Fish The results of gamma spectrometric analyses of fish samples collected during 1989 are presented in Table 19. A total of eleven samples were analyzed, six from the indicator location ENE-2 and five from the control location NNE-8. Sampling efforts concentrated on tne larger edible species of commercial and/or recreational imoortance. Cesium-137 was detected in one of the samples with an average activity of 13 pC1/kg wet. Naturally occurring potassium-40 was detected in all samples. The ! average potassium-40 concentration for the six indicator s amples is 3485 pCi/kg wet with a range of 2730 to 4490 pCi/kg wet. The average concen-tration for the control location is 3144 pCi/kg wet with a range of 1960 to 3930 pCi/kg wet. l F. Shoreline Sediments The processes by which radionuclides and stable elements are concen-trated in bottom sediments are complex, involving physiochemical interaction 15 i
I I in the environment between the various organic and inorganic materials f rom the watershed. These interactions can proceed by a myriad of steos in which the elements are absorbed on or displaced from the surf aces of col-lodial particles enriched with Chelating organic materials. Biological action of bacteria and other benthic organisms also contribute to tne con-centration of Certain elements and in the acceleration of the sedimentation process. Results of the gamma isotopic inalyses of the sediments samDiej from the CPSES environment are given in Table 20. For 1989 three locations, one control and two indicators, were sampled semiannually. The average, fraction of detectables, and range of radionuclide concentrations are summarized in Table 22. Gamma emitters found in detectable concentrations were K-40, Pb-212, Ra-226, Bi-214, Pb-214 and Th-228 Be-7 and Cs-137. G. Food Products and Broadleaf Veoetation Results of camma spectrometric analyses of vegetation samples are contained in Table 21. A total of 47 samples were analyzxed from 5 loca-tions. Potassium-40, a naturally occurring isotooe, was found in 47 samoles. The average potassium-40 activity for the control location was 4837 pCi/k1 wet with a range of 896 to 9810 pCi/kg wet. For the indicator locations the average potassium-40 activity was 4959 pC1/kg wet with a range of 1570 to 12300 pC1/kg wet. Naturally occurring beryllium-7 was detected in twenty-one indicator samples with an average activity of 1781 pCi/kg wet; the range was 359 to 5670 pCi/kg wet. Fourteen samples from control station, SW-13.5 were found to have beryllium-7 with an average activity of 1294 pCi/kg (wet) and a range of 225-3120 pCi/kg (wet). Iodine-131, cesium-134 and cesium-137 were below the lower limit of detection in all samples. 16

I I I V. CONCLUSIONS It can be concluded from the levels and fluctuations of radioactivity obtained in envi ronmental samples during 1989, that sensitive indicators of radioactivity for the environment around the CPSES have been selected. The atmospheric environment was sampled for airborne particulate matter, radioiodine, and direct radiation. The terrestrial environment was sampled for milk, ground-drinking water, surf ace-drinking water and food products. The aquatic environment was sampled for surf ace water, fish and shoreline I sediment. The analyses of these samples provided results which were either below the measurement detection limits or were indicative of natural ter-restrial and cosmic ray radiation levels. I I I I I I I I 18

At that time, the drinking water analyses were eliminated and subsequent samples were analyzed pursuant to the 00Cl1 surface water analysis requirements of nonthly gamna-iostopic and quarterly tritiun composite.
**The required LLO for 1-131 in water if there is no drinking water pathway is 15 pCi/1. This LLD was not achieved due to confusion I over climination of the 1-131 analysis for drinking water discussed in the above notation.

I I ANALYSIS OF SAMPLES FOR 100!NC 131 I Milk or Water Two liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin is used to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, is reduced with hydroxylamine hydrochloride and is extracted into carbon tetrachloride as free iodine. It is then back extracted as iodide into sodiurn bisulfite solution and is precipitated as palladium iodide. The I precipitate is weighed for chemical yield and is mounted on a nylon planchet for low level beta counting. The chemical yield is Corrected by measuring the stable iodide content of the milk or the water with a specific ion electrode.

This material has a high light output, negligible thermally induced signal loss (f ading), and negligible self dosing. The energy response curve (as well as all other features) satisfies NRC Reg. Guide 4.13. Transit doses are accounted for by use of separate TL0s. Following the field exposure period the TLDs are placed in a Teledyne Isotopes Model 8300. One fourth of the rectangular TLD is heated at a time and the measured light emission (luminescence) is recorded. The TLD is then annealed and exposed to a known Cs-137 dose; each area is then read again., This provides a calibration of each area of each TLD af ter every field use.

I 1 I DETERMINATION OF GROS $ alpha AND/OR GROSS BETA ACTIVITY IN WATER SAMPLES
1.0 INTRODUCTION
The procedures described in this section are used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved. One liter of the sample is evaporated on a hot plate. Different volumes may be used if the sample has a significant salt content as measured by a conductivity meter, or if unusual sensitivity is desired. If requested by the customer, the sample is filtered through No. 54 filter paper before evaporation, removing particles greater than 30 microns in size. Af ter evaporating to a small volume in a beaker, the sample is rinsed into a 2-inch diameter stainless steel planchet which is stamped with a concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place under heat lamps. Samples which appear to be hygroscopic are dried again under heat lamps just prior to counting. Residue mass is detemined by weighing the planchet before and after mounting the sample. The planchet is counted for alpha and/or beta activity on an automatic proportional counter. Results are calculated using empirical self-absorption curves which allow for the change in effective counting efficiency caused by the residue mass. l l l 71
I 1 2.0 DETECTION CAPABILITY Detection capability depends upon the sample volume actually repre. sented on the planchet, the background and the efficiency of the counting instrument, and upon self-absorption of alpha and beta particles by the mounted sample. Because the radioactive species are not identified, no decay corrections are made and the reported activity refers to the cuunting time. The minimum detectable level (MOL) for water suples is nominally l 1.6 picoeuries per liter for gross beta at the 4.66 sigma level (1.0 pCi/l at the 2.83 sigma level), asstning that 1 liter of suple is used and that 1/2 gram of suple residue is mounted on the planchet. These figures are based upon a nominal counting time of 50 minutes and upon representative values of counting efficiency and background of 0.2 and 1.2 cpm, respectively. The MOL for gross alpha activity is nominally 2.3 picoeuries per litec at the 4.66 sigma level (1.4 pCi/t at the 2.83 sigma level) also assuming thot 1 liter of suple is used and that 1/2 gra of smole residue is mounted on the planchet. These figures are based upon a nominal 200 minute counting time ard upon a representative efficiency of 0.02 and a background of 0.1 cpm. The MDL becomes significantly lower as the mount weight decreases because of reduced self-absorption. At a zero mount weight, the 4.66 sigma MOL for gross beta is 0.9 picrocuries per liter and the MOL for gross alpha is 0.3 picoeuries per liter. These values reflect a beta counting efficiency of 0.38 and an alpha counting ef ficiency of 0.18. 72

The sampling program requirements that could be affected by changes in land use ares (1) Milk - ODCM Table 3.12-1 requires that samples be obtained from milking I animals in three locations within 5 km having the highest potential dose. If none are available, samples are acceptable f rom milking animals in locations 5 to 8 km distant where doses are calculated to be greater than 1 mrem per year. A sample is also required at a control location. Currently, milk samples are collected at one indicator location (SSE-2,2) and at a control location. (2) Food Products - ODCM Table 3.12-1 requires that one sample of each principal class of food product be collected f rom any area that is irrigated with water _ in which liquid plan: wastes have been discharged. Currently, food products are sampled from two indicator locations: (ENE-9.0, Pecans; E-4.2, vegetables) and one control location. (3) Broadleaf Vegetation - ODCM Table 3.12-1 requires a sample of broadleaf vegetation from each of two of fsite locations of highest predicted annual average D/Q if milk sampling is not performed at all required locations. I currently, broadleaf vegetation samples are collected at two indicator locations (N-1.45 and SW1.0) and one control location. These locations are near the site boundary in sectors where broadleaf is available and D/Q is greatest. Based on these requirements, the milk animals identified at locations NNE-4.5 and VNW4.0 were evaluated f or possible inclusion in the RDfP. The land owners at these locations were contacted by Chemistry and Environmental Personnsi and it was determined that these milk animals are not milked and tre not available for sampling. Also, the goats identified at location NE-3.9 are considered " brush goats" and are not available for sampling. Therefore, no changes to the milk sampling locations of the REMP are required. Of the gardens that were identified, no new gardens were identified that are irrigated with water in which liquid plant vastes are discharged. Therefore, no change to the REMP is required. Finally, since broadleaf vegetation is currently collected at the site boundary, no changes to broad leaf sampling locatione are required. There are no identified locations closer to the plant.
