GENERAL $ ELECTRIC ABSTRACT ANNUAL

SUMMARY

, 1987 The data tables in this report include.all results for the current calendar year 1987.

On November 25, 1987, approximately 7,000 gallons of liquid and solid sanitary wastes were removed from the site Imhoff tank by A-1 Septic Tank Service, Inc., 1111 Industrial Parkway, Hayward, California (now being disposed of at the San Jose Treatment Plant in Milpitas, California).

All treated sanitary waste water has been disposed of on site by a sprinkler irrigation system. No surface runoff was observed during the report period.

All VNC liquid waste releases were well within the radioactivity compliance limits.

EFFLUENT MONITORING AND ENVIRONMENTAL SURVEILLANCE PROGRAMS ANNUAL SUtiMARY - 1987 VALLECITOS NUCLEAR CENTER R. E. Gest I.

INTRODUCTION This report sumarizes activities and data for the Effluent Monitoring and Environmental Surveillance Programs for the calendar year of 1987 at the Vallecitos Nuclear Center.

Effluent monitoring includes measurements of airborne radioactivity releases from facility stacks and the measurement of radioactive and nonradioactive constituents in water discharged through the site sanitary and industrial wastewater systems.

Environmental surveillance encompasses the measurement of radioactivity in air near the site perimeter and the measurement of both radioactive and nonradioactive constituents in neighboring streams, wells, soils and vegetation.

A.

EFFLUENT MONITORING PROGRAM The Effluent Monitoring Program has been developed 'a ensure that VNC site release limits for water are not exceeded and, additionally, to ensure that releases are maintained as low as reasonably achievable.

Release limits for numerous nonradiological constituents have been established by the California Regional Water Quality Control Board (CRWQCB).

Radiological release limits have been established by the Nuclear Regulatory Comission (NRC) and by the California State Department of Health Services (CSDHS).

s 1.

Waterborne Effluents Waterborne effluents released from VNC site facilities can be classified l

as industrial wastewater or clean water.

I

Industrial wastewater includes process and cooling water which is first piped to a pH adjustment facility before discharge to one of three available 60,000 gallon retention basins.

Tests for pH and radioactivity are performed on a water sample from each basin prior to discharge into Vallecitos Creek.

In addition, samples from all basin discharges are accumulated and analyzed at specified intervals for a variety of constituents.

Clean water discharges consist of storm runoff and small quantities of water known to contain no contaminants (by addition of sodium hypochloride solution).

The latter includes condensate from building air conditioning equipment.

These waters flow directly to drainage ditches which enter Vallecitos Creek.

Sanitary wastes are collected and processed in a septic tank before undergoing sand filtration and chlorination.

Processed sanitary wastewater is discharged by land disposal (irrigation) onto VNC property (Figure 1).

2.

Airborne Effluents Airborne effluents consist of discharges from VNC facility stacks.

Stack releases are monitored for radioactivity even though multistage filtering is accomplished prior to discharge.

B.

ENVIRONMENTAL SURVEILIANCE PROGRAM Water samples are obtained within or beyond the site boundary to ascertain to what extent, if any, VNC discharges are detectable in the environment.

Receiving waters, ground water, and stream bottom sediments are monitored for constituents which could have been dispersed by water.. Air samples are utilized to detect the presence of radioactivity in air, and vegetation samples have been collected and analyzed in the past to assess the accumulation of constituants from both air Lsd water pathways.

The airborne release data are published only in this report.

COMPLIANCE

SUMMARY

1.

Nuclear Regulatory Commission and California State Deoartment of Health Services All VNC liquid waste releases were well within the limits specified by these agencies.

There were no items of noncompliance.

Compliance limits are listed in 10CFR20 Appendix B and California Administrative Code Title 17, Section 30355.

Compliance with these limits for the release of individual basins is determined by gross alpha and beta analyses based on the most restrictive isotopes which could reasoncbly be introduced into the system.

Airborne effluents consist of discharges from VNC facility stacks.

Stack-releases are monitored for radioactivity even though multistage filtering is accomplished prior to discharge.

2.

California Recional Water Quality Control Board (CRVOCB)

Nonradioactive discharge parameters are established by CRWQCB Order 84-76 and NPDES Permit No. CA0006246. Unless noted in the Abstract to this report. all industrial wastewater discharged from the site met the limits set in those documents. The permit does not allow the discharge of sanitary waste.

That material is processed and disposed of to the land via an irrigation system.

Although the discharge permit issued to VNC does not specify sampling criteria for this land discharge, the following sampling program is being i

practiced:

a.

Total coliform (two times a month) b.

pH (per discharge) c.

Radioactivity (per discharge)

Records of these test parameters are being maintained at VNC.

Listing of Laboratories and Analyses Performed A listing of laboratories which perform analyses is shown in Figure 2.

One external laboratory is approved by the California State Department of Health.

In September, 1979, GE-VNC established a new contract with an outside vendor for analysis of radiological samples. As a result, the method of reporting sample results changed in that the actual analytical results obtained from measurements are reported; this is to be contrasted with the previous method of reporting results as "less than the minimum sensitivities of measurement".

This change does not necessarily mean that more sensitive analyses are performed on any given sample. Samples analyzed on site are reported as above or less than values, while contract service samples are reported as actual measured values.

Values determined to be within the statistical background for the contract service samples may be listed in the table as positive or negative numbers.

WATER *0RNE RELEASES 1.

Influent and Effluent Daily industrial and sanitary wastewater discharge and monthly influent volumes are sumarized in Table 1.

2.

Influent (Nonradioactive Parameters)

A summary of data relating to nonradioactive influent parameters is given in Table 2.

3.

Influent and Effluent (Radioactivity Parameters)

Radioactivity measurements for influent and effluent waters are sumarized in Tables 3 and 4.

Table 3 indicates essentially no difference between measurements of influent (from the San Francisco water supply system) and monthly composites of industrial effluent.

Aliquots of daily samples are combined to form the monthly composite.

The monthly composite results will differ from a simple sumation of daily (1) the monthly composite analysis is performed sample analyses because:

by a contractor laboratory with minimum sensitivities different from site counting equipment; (2) the monthly composite analysis is performed on a such larger sample; and (3) most of the short half-life naturally occurring radioisotopes have decayed below detectability by the time the monthly composite is analyzed.

The data in Table 3 are derived by suming data obtained from measurements of short-interval (daily) water releases. Many of these measurements were less The data than the detection limits of the laboratory's measurement methods.

listed as "less than" numbers necessarily include the sumation of these detection limits (i.e., a sumation of "less than" numbers) and represent maximum possible values for the sample analyses.

STACK MONITORING Ten stacks at VNC required either regular or intermittent sampling during 1987.

Data for each stack are given in Table 25A.

The operating components serviced are given in Table 25B.

Each of these stacks is equipped with a sampling line that contains a particulate filter for sampling particulate radioactivity.

Selected sample lines are also equipped with charcoal cartridges for radioiodine monitoring.

Other stacks are equipped with noble gas monitoring systems.

Filters and cartridges are changed weekly and analyzed for gross alpha, gross beta-gamma, and I-131.

The noble gases are counted continuously, and a recording system provides a readout of the quantity released from each monitored stack.

Results of the VNC stack sampling program are presented in Figures 3 through 6.

Figures 3 and 4 present the emissions from the two* major VNC stacks, Building 102 (Stack 4) and the Nuclear Test Reactor (Stack 16).

Figure 5 is a composite of the remaining minor stacks.

Figure 6 is a composite of all VNC stack discharges.

Because of the removal of materials from the GETR, the GETR stack is no longer classified as a major stack.

Total airborne releases (stack emissions) for 1987 are as follows:

Alpha Particulate:

< 2.01 pCi (predominantly radon-thoron daughter products)

Beta-Gamma Particulate: < 22.5 pCi Iodine-131:

< 0.20 mci 2

Noble Cases:

4.78 x 10 Ci Noble gas activities recorded from Stack 16 integrate background readings with the actual releases, which, in some cases, account for 40 to 50% of the activity released.

Stack 4 data have been corrected for background.

As with the water effluent data, these data above are derived by summing data obtained from measurement of short-interval releases. Many of the measure-ments on these releases were found to be less than the detection limits of standard laboratory instru=entation. The data listed include the multiple summation of these detection limits and therefore represent the maximum releases possible from the VNC during the calendar year.

SURVEILLANCE FOR AIRBORNE RELEASES 1.

Environmental Air Samoles Environmental air monitoring stations are positioned approximately 90* apart around the operating facilities of the site (see Figure 10).

Each station is equipped with a membrane filter.

Filters are analyzed for gross alpha and gross beta-gamma. Results are graphed in Figure 11.

2.

Cloud-Gamma Monitors There are 31 stations on site for measuring cloud gamma radiation.

These are located in sixteen 22.5* sectors surrounding the facilities. Each station consists of a thermoluminescent dosimeter (LiF or CaSo :Dy) sealed in a plastic-coated aluminum foil package 4

which is placed in a protective brown paper covering.

These dosimeters are changed once annually (Station 4, quarterly).

Station locations are shown in Figure 10.

South boundary stations are numbers 1, 2, 3, 8, 9, 31; East boundary stations are numbers 10, 11, 12, 13, 14, 15; North boundary stations are numbers 16, 17, 18, 19, 23, 24; and West boundary stations are numbers 25, 26, 27, 28, 29, and 30.
