1.0 INTRODUCTION
This report summarizes activities performed and data collected for the Effluent Monitoring and Environmental Surveillance Programs at Vallecitos Nuclear Center !VNC). Section 1.0 presents background information. Data collected during the reporting period is presented in Section 2.0 through 4.0. This report has been prepared to demonstrate compliance with state and federal requirements.
The VNC site is several hundred acres in size. It is located on the northern side of Vallecitos Valley as shown in Figure 1, a topographic map of VNC and the surrounding area. Most of the site is undeveloped with hills ranging in elevation from approximately 1,000 to 1,300 feet above mean sea level. Approximately 135 acres in the southwest corner and situated between the 400 and 600 foot topographic contours are developed. The ground surface of this portion of the site slopes to the southwest.
VNC utilizes three drainage systems: industrial, sanitary, and storm. The industrial and sanitary systems discharge effluent into one of four 50,000-gallon retention basins located in the southwest corner of the site (Figure 2). The storm drainage system, essentially natural ditches, discharges storm water into a ditch parallel with Vallecitos Road !State Route 84). Storm drains from Buildings 103, 104, and 106 discharge to the west drainage ditch, while some storm drains in the Building 102, 105, 200, and 300 areas discharge to the east drainage ditch. As shown in Figures 2 and 3, these ditches merge prior to exiting the southwest corner of the site.
Groundwater levels of the developed site vary from 2 to 3 feet below ground surface !during winter near Retention Basins 2 and 3) to 30 to 40 feet (during the summer northwest of the road leading to the water tank).
A USGS geology study shows that groundwater generally flows toward the southwest. The velocity of groundwater is estimated by USGS to be about 0.01 ft/day in clays to 8ft/day in gravels. In areas where gravels with a considerable mixture of clay !most of developed site) are saturated close to the land surface, southwesterly movement occurs at an average rate of approximately 2 ft/day1.
1.1 Effluent Monitoring Program The purpose of the Effluent Monitoring Program is to ensure that VNC site release limits for effluent are not exceeded. The Program includes measuring radioactive and non-radioactive constituents in water discharged through the site sanitary and industrial wastewater systems. Measurements are determined by collecting samples of effluent. The schedule of sample collection is presented in Table 1.
The California Regional Water Quality Control Board !CRWQCBI has established release limits for numerous non-radiological constituents through Water Discharge Permit No. R2-2008-0079. A copy of the 2008 permit is on file at VNC and CRWQCB. The California State Department of Health Services !CSDHSI and the United States Nuclear Regulatory Commission !NRC) have established radiological release limits. These limits are listed in 10CFR20, Appendix B.
Effluent Characteristics Effluent discharge from VNC is mode up of industrial wastewater and clean water. Discharges of industrial wastewater consist primarily of non-contact cooling water. The discharges are either held in one of three available 50,000-gollon retention basins and or used for non-potable purposes, such as landscape watering.
After July 1st, 2003 no discharges to surface waters have been made from these sources. Samples are collected from each basin prior to discharge to on site irrigation. In addition, samples from all basin discharges are accumulated and analyzed at specified intervals for a variety of constituents.
Discharges of clean water consist of storm water runoff and small quantities of water known to contain no contaminants. These waters flow directly to drainage ditches that enter Vallecitos Creek.
Sanitary Waste Handling Sanitary waste !sludge) is collected in an Imhoff tank before undergoing sand filtration and chlorination !by addition of sodium hypochlorite solution). Samples of sanitary waste !sludge) are collected before each Imhoff 1 A delay of over 2 years from the nearest postulated spill paint to the site boundary.
1
Tank clean-out There were no clean-outs performed on the Imhoff tank during 2018. Processed sanitary waste water is sprayed onto VNC property by an irrigation system in a designated area (Figure 2). The procedure is monitored so that no surface runoff occurs.
1.2 Environmental Surveillance Program The purpose of the Environmental Surveillance Program is to determine if discharges from VNC are detectable in the environment The Program includes measuring both radioactive and non-radioactive constituents in neighboring streams, wells, and soils at locations near or beyond the site perimeter. Samples of groundwater, stream bottom sediments, and vegetation are collected. The schedule of sample collection is presented in Table 1.
Groundwater Monitoring Groundwater is monitored by collecting and analyzing samples from ten wells located on or near VNC.
Samples are analyzed for State water permit effluent parameters as well as radiological contaminants. Well identification numbers, corresponding California State Well Numbers, and descriptions of locations are listed in Table 2. Wells installed in the early 1970s in and around Building 102 are checked on a quarterly basis for water. Some of these wells have been dry for several years and sampling is not possible. When samples are collected from these sources, they are sent to the counting lab on site for analysis.
Vegetation Monitoring Vegetation is monitored by collecting and analyzing samples of vegetation at two locations designated V-2 and Vai-IV.
Station Description V-2 Easternmost stream crossing south boundary of site VAL-IV West of site boundary, 500 feet down Little Valley Road Stream Bottom Sediment Monitoring Stream bottom sediment is monitored by collecting and analyzing samples at one location designated as S-4.
The location is at the outfall of the retention basins at south boundary of site.
Air Monitoring There are four air monitoring stations, designated as A-1 through A-4, across the site. The stations are positioned approximately 90° apart around the operating facilities of the site. The locations of the stations are shown in Figure 4.
To collect samples, each station is equipped with a membrane filter and an activated charcoal cartridge. The filter is changed weekly2 and counted for gross alpha and gross beta radiation. The cartridge is removed and analyzed only in the event of a suspected radioactive iodine release.
Gamma Monitoring There are 20 monitoring stations on site for measuring gamma radiation in the environment. Each station is constructed of a steel mailbox and equipped with a dosimeter. The dosimeter is sealed in plastic. The dosimeters are exchanged annually. The locations of the stations are shown in Figure 4.
For reporting purposes, the dosimeters are distributed as follows:
South Boundary-Stations 1, 2, 3 East Boundary-Stations 4,5,6 North Boundary-Stations 7,12,13 West Boundary-Stations 8,9,10,11 Background Dosimeters -Stations 14,15,16,17,18,19,20 2 During dusty conditions, the filters are changed as determined by the RMT, Facilities Protection.
2
The dosimeter vendor reports the measurements of each dosimeter and determines the background measurement Background is determined by using a dosimeter that has been exposed to background radiation at this facility and is from the same batch of OSL material as the dosimeters exposed at VNC.
Gaseous Effluent Monitoring Several operations at the site utilize exhaust stacks. Air is collected from single or multiple operating areas via a ventilation system. The ventilation system is generally comprised of ductwork, particulate filtration systems, blowers, and an exhaust stack. The gaseous effluent is monitored. The specifications of each stack are listed in Table 3.
The various site operating licenses ISNM-960, R-33, and State 0017 -01) and federal regulations require that the gaseous effluents released to unrestricted areas be limited and controlled to maintain the concentrations of radioactive material in the unrestricted area as low as reasonably achievable but at least no greater than the values in Appendix B, Table II of 10CFR20.
The method by which releases are determined to be within these limits is to establish average release limits and control values for each stack and then measure the average releases through monitoring and/or sampling of the effluents. The control values are, in general, established as 10% of the license release limits.
Both sampling and monitoring techniques are used to determine gaseous effluent releases. Release results reported to regulatory agencies for particulates and halogens are obtained from sampling systems. Noble gas results are obtained from charts or electronic integrators on monitoring equipment The COMPLY computer code is run to determine the dose at the site boundary from annual airborne effluents.
This evaluation was formerly required when 40CFR61 Subpart I applied to NRC licensees, which inciuded VNC.
The regulation was amended to exclude NRC licensees. However, VNC has continued to run the COMPLY code to demonstrate compliance with the constraint rule per Regulatory Guide 4.20 and 10CFR20.1101d. Verifying compliance with annual public dose per 10CFR20.1301, "Dose limits for individual members of the Public'.
1.3 Laboratory Analyses On-site and external laboratories perform the analyses of samples collected at VNC as required for the programs. Samples analyzed by the on-site laboratory are reported as measured value or less than minimum detectable activity IMDAI values, while samples analyzed by the external laboratories are reported as actual measured values. Values within the statistical background may be listed as zero or as a positive or negative numbers. All analyses are performed using approved USEPA methodology with minimum sensitivities equal to or less than permit limits. All records of analytical results are maintained at VNC.
On-site Laboratory Analyses The following list of analyses are performed by the on-site laboratory:
pH Dissolved Oxygen Total Alpha-Emitting Radioactivity Total Beta-Emitting Radioactivity Off-site Laboratory Analyses The three external State-certified laboratories that have been contracted to analyze samples collected for the program are Test America Laboratories, Inc., Alpha Analytical Laboratories, Inc. and Davi Lab. Alpha Labs, located in Livermore. California, or Test America, located in Pleasanton, California, performs Total Ammonia las Nl. Nitrates las N03) Total Dissolved Solids, total coliform. and analyses of water samples as required. Davi Lab, located in Hercules, California, performs most radiological analyses on samples of water. stream bottom and vegetation.

No surface runoff of sanitary or industrial waste occurred during the report period.
Based on the analytical results of non-radiological samples collected from locations on-site during the reporting period, VNC is in compliance with the limitations set in the Waste Discharge Requirements Order No.
GE-R2-2008-0079.
Based on the analytical results of radiological samples collected from locations on and off-site during the reporting period, VNC is in compliance with all licenses issued by the U.S. Nuclear Regulatory Commission and California Department of Health, Radiologic Health Branch.
Discharge Volume Data Industrial and sanitary wastewater discharge volumes are summarized in Table 4.
Non-radiological Analytical Results Summaries of data relating to non-radioactive effluent parameters are given in Table 5 through 9. The results indicate that all constituents of concern are in compliance with regulatory limits.
Radiological Analytical Results Radioactivity measurements for effluent waters are summarized in Table 10. The data are derived by summing data obtained from measurements of short-interval (daily) water releases. Many of these measurements were less than the detection limits of the laboratory's measurement methods. The data listed as "less than" numbers necessarily include the summation of these detection limits (i.e., a summation of "less than" numbers) and represent maximum possible values for the sample analyses. The results indicate that no radiological material was released that exceeded regulatory limits.
