1.0 INTRODUCTION
Th1s report summarizes activities performed and data collected for the Effluent Monitoring and Enwonmentol Surveillance Programs at Vallecitos Nuclear Center IVNCI. This sect1on presents background 1nformat1on about the Programs. Data collected dunng the reporting period ore presented in Section 4 0. Th1s report has been prepared in compliance with Waste Water Permit requirements.
The VNC site 1s several hundred acres in size. It is located on the northern side of Vallecitos Volley as shown in Figure 1, o topographic mop of VNC and the surrounding area. The majority of the site is undeveloped with h11ls 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 ore developed. The ground surface of this portion of the site slopes to the southwest VNC utilizes three drainage systems: industnol, somtory, and storm. The industrial and sanitary systems d1schorge effluent into one of four 50,000-gollon retention 1,1asins located in the southwest corner of t11e site
!Figure 21. The storm dr01noge system, essentially natural dftches, discharges storm water into o ditch parallel with Vallecitos Rood !State Route 841. Storm drains from Buildings 103, 104 and 106 d1schorge to the west dr01noge ditch. wh1le some storm drains in the Building 102, 105, 200 end 300 oreos discharge to the eost drainage ditch. As shown in Figures 2 and 3. these ditches merge prior to exiting the site.
Groundwater levels of the developed site vary from 2 to 3 feet below ground surface (dunng winter neor Retention Basins 2 and 31 to 30 to 40 feet (during the summer northwest of the rood leading to the water tonkl.
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/doy in cloys to 8 ftldoy in grovels. In areas where grovels with a considerable mi><ture of cloy !most of developed site) ore saturated close to the land surface.
southwesterly movement would occur at on overage rote of approximately 2 ft/doy\\
1.1 Effluent Monitoring Program The purpose of the Effluent Monitonng Program IS to ensure that VNC site release limits for effluent ore not exceeded. The Program i11cludes measuring radioactive ond non-radioactive constituents in water discharged throl,lgh the sitesomtory and industrial wastewater systems. Meosu*rements ore determined by coiiecting samples of effluent. The schedule o( sample collection IS presented in Table 1.
The California Regional Water Quality Control Boord ICRWQCBI has established release limits for numerous non-rodiologtcol constituents through Water Discharge Permit No. RZ-2008-0079. A copy of the 2008 permit is on file at VNC and CRWQCB. The California State Deportment of Heolth Services (CSDHSI and the United States Nuclear Regulatory Commission INRCI hove established radiological release limits. These limits ore listed 1n 10CFR20, Appendix B.
Effluent Characteristics Effluent discharge from VNC is made up of industrial wastewater and clean water. Discharges of industnol wastewater consist primarily of non-contact cooling water. The discharges ore either held in one of three ovotloble 50.000-gollon retention basins or used for non-potable purposes, such as landscape watering. After July l*t, 2003 no discharges to surface waters hove been mode from these sources. Samples ore collected from each bos1n prior to discharge to on site irrigation. In addition, samples from oil basin discharges ore accumulated and analyzed at specified inteNals foro variety of constituents.
D1schorges of clean water consist of storm water runoff and small quantities of water known to contain no contaminants (such as Irrigation runoff). These waters flow directly to drainage d1tches that enter Vallecitos Creek.
Sanitary Waste Handling Sanitary waste !sludge) is collected 1n on Imhoff tonk before undergomg sand filtration ond chlorination (by addition of sod1um hypochlorite solution I. Samples of sanitary waste !sludge) ore collected before each Imhoff l A delay of over 2 yeors from the nearest postulated spill pomt to the site boundary.

Tonk clean-out. There were no dean-outs performed on the Imhoff tonk during 2017. Processed sanitary waste water ts sprayed onto VNC property by Oll irrigotton system in a destgnoted area (Figure 21. 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 ore detectable in the environment The Program includes measuring both rodtoocbve and non-rodtooctive constituents in neighbo~ng streams. wells, and soils at locations near or beyond the s1te perimeter. Samples of groundwater.
stream bottom sediments, and vegetation ore 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 radtologicol contaminants. Well tdentificotion numbers, corresponding California State Well Numbers, and descnptions of locations ore listed tn Table 2. It should be noted that the wells installed 1n the early 1970s in and around Buildtng 102 ore checked on o quarterly basts for water. Some of these wells hove been dry for several years and sampling ts not possible. When samples ore collected from these sources. they ore sent to the counting lob on site for analysts Vegetation Monitoring Vegetation is monitored by collecting and onalyz1ng samples of vegetatton at two locottons destgnoted V-2 and Voi-IV. The locations ore shown in Figure.3.
Stream Bottom Sediment Monitoring Stream bottom sediment is monitored by collecttng and analyzing samples at one location designated as 5-4 The location IS at the outfall of the retention basins at soUth boundary of site, wh1ch 1s shown tn Figure 3.
Air Monitoring There ore four air monitoring stations. destgnoted as A-1 through A-4, across the site. The stations ore positioned oppro><imotely 90° aport around the operating facilities of the site. The locations of the stottons ore shown tn Figure 4.
To collect samples, each station 1s equtpped wtth a membrane filter and an acttvated charcoal cortndge The filter ts changed weeklyz and counted for gross alpha and gross beta-gamma radiation. The cartridge is removed and analyzed only tn the event of a suspected radioactive iodine releose.
Gamma Monitoring There ore 20 monitoring stations on site for measuring gamma radiation in the environment. Each station is constructed of o steel mailbox and equipped with o dosimeter. The dosimeter is sealed in plastic. The dosimeters ore exchanged annually. The locations of the stations ore shown in Figure 4.
For reporting purposes. the dostmeters ore distributed as follows:
South Boundary-Statior1s 1, 2. 3 East Boundary-Stations 4,5,6 North Boundary-Stottons 7,12,13 West Boundary -
Stations 8,9,10,11 Background Dostmeters -Stations 14,15,16,17,18,19,20 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 ot this facility ond is from the some botch of OSL materiel os the dosimeters e><posed at VNC.
l Dunng dusty condttions. the filters ore changed os determined by the RMT, Faciltttes Protectton.

Gaseous Effluent Monitoring Several operations at the s1te utilize exhaust stocks. Air is collected from single or multiple operot1ng areas via a ventilation system. The ventilot1on system is generally comprised of ductwork. particulate filtration systems.
blowers. and on exhaust stock. The gaseous effluent is monitored. The specifications of each stock ore listed in Table 3.
The various site operating licenses (SNM-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 ll of 10CFR20.
The method by which releases ore determined to be with1n these hm1ts is to estobhsh average release limits and control values for each stack and then measure the overage releases through monitoring and/or sampling of the effluents. The control values ore, 1n general, established os 10% of the license release hmits.
Both sampling and mor11tonng techniques ore used to determine gaseous effluent releases. Release results reported to regulatory agencies for particulates and halogens ore obtained from sampling systerns. Noble gas results ore obtained from charts or electronic integrators on rnonitonng equipment The COMPLV computer code is run to determine the dose at the site boundary from annual airborne effluents.
This ~voluot1on was formerly required when 40CFR61 Subpart I applied to NRC licensees. which included VNC.
The regulation was amended to exclude NRC licensees. However, VNC has continued to run the COMPLV code to demonstrate compliance with the constraint rule per Regulatory Guide 4.20 and 10CFR20.1101d. Verifying compliance wtth 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 ore reported as measured value or less than m1nirnum detectable activity IMDAI values. while samples analyzed by the external laboratories ore reported os actual measured values. Values within the statistical bac~ground may be listed as zero or as o positive or negative numbers. All analyses ore performed using approved US EPA methodology with minimum sensitivities equal to or less than permit limits. All records of analytical results ore maintained at VNC.
On-site Laboratory Analyses The following list of analyses are performed by the on-site laboratory:

2.0 EFFLUENT MONITORING DATA This section presents the d1schorge information and analytical results for samples collected for the Effluent Monitoring Program during the reporting period.
Effluent Data Compliance Summary Required samples were collected during the reporting period and the analytical results of tests d1d exceed Permit limits. During the months of January to November. no exceedances were tdentified. For the month of December, o review of monthly discharge volumes identified a Nitrate !as N03l exceedance for waste water.
Treated sanitary and industrial wastewater was disposed of on-site by an irrigation system. No surface runoff of sanitary or industrial wastes was observed during the report period.
Based on the analytical results of non-radiological samples collected from locations on-site during the reporttng period, VNC was in compliance with the limitations set in the Waste Water Permit No. GE-R2-2008-0079.
Based on the analytical results of radiological samples collected from locations on and oft-site during the report1ng period, VNC was in compliance with all licenses 1ssued 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.
Nan-radiological Analytical Results Sllmmones of data relating to non-radioactive effluent parameters are given in Table 5 through 9. The results indicate that for the month of December, Nitrate (as NO,) was released greater than permit limit No other constituents were released equal to or greater than regulatory limits for any other time during 2017.
Radiological Analytical Results Radioactivity measurements for effluent waters are summarized in Table 10. The data ore derived by summing data obtained from measurements of shart-inteNol !doily) 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 1ndude the summation of these detection limits (i.e.* o summation of "less than* numbers! and represent maximum possible values for the sample analyses. The results indicate that no radiological material was released equal to or greater than regulatory limits.
