p t E' I. INTRODUCTION v ' _) ' This document is issued as a supplement to two documents originally pre-pared in support of renewal applications for Special Nucleai Materials License No. SNM-21..The first of these, AI-76-21 " Environmental Impact Assessment of Operations at Atomics International Under Special Nuclear Materials License SNM-21," was prepared in support of the aplication for renewal of the license submitted in June 1975. The second ESG-82-32, " Environmental Assessment of Operations at Energy Systems Group of Rockwell International Under Special l Nuclear Materials License SNM-21," was prepared as a supplement to AI-76-21 and submitted in support of the license renewal application in August 1982. The present document has been prepared to update those sections of the 1976 and 1982 reports that are time dependent, or which require updating to include the most recent data available. The following subject areas in the earlier reports are included in those categories and thus are updated in this supplement. w. 1. Democraohv. Originally presented in Part A Chapter VII of AI ( 21, and updated with best available data in ESG-82-32. V) 2. Meteoroloav. Originally discussed in Part A, Chapter VI of AI 21, and included-here to provide improved data. 3. Emission Rates and Concentration Values. Originally provided in Part B, Chapter IV of AI-76-21, updated in ESG-82-32, and included here to provide current data on recent activities. 4. Radioloaical Pollutants in Environmental Samoles. Originally in Part B, Chapters VII, VIII, and IX of AI-76-21, updated in ESG 32, and included here to provide current data on recent activities. 5. Nonradioloaical Pollutants. Originally in Part B, Chapter XII of; AI-76-21, updated in ESG-82-32, and also included here to present current data on recent operations. ( ') RI/RD89-180 \\~' 3

f .The information on land use, hydrology, and geology presented in Chap-- 7 ters III, IV, and V, respectively, of Part A of AI-76-21 is still cons!dered { L' to be valid. No additional information worthy of inclusion here appears to be i available. However, it should be noted-that two earthquakes which were felt at the licensed Rockwell facility have occurred since the publication of ESG-82-32. Pertinent information on these quakes is given in Table 1. While both quakes were felt at the Rockwell Hot Cell, there were no injuries, no damage, and no spill or releases of any radioactivity at not only the Hot Cell, but also other Rockwell facilities at the Santa Susana field Laboratory in the immediate vicinity of the cell. Table 1. Earthquakes Felt at the Rockwell Hot Cell Date: October 1, 1987 January 18, 1989 Time: 7:42 a.m. (local) 10:53 p.~m. (local) Magnitude: 5.9 Richter 5.0 Richter Epicenter: 34' 3.7' N latitude 33' 55.l' N latitude 118' 4.7' H longitude 118' 37.6' H longitude l Hypocenter V' (depth): 9 km 12 km y Duration: 20.04 set 28.84 sec The emergency procedures submitted to NRC in ESG-81-30 and cited in ESG-82-32 have recently been updated and revised to reflect the current licensed facilities and operating organization covered in License No. SNM-21. This revised document, RI/RD88-205, "On-Site Radiological Contingency Plan for Rockwell International Operations Licensed Under Special Nuclear Materials License No SNM-21," has superceded ESG-81-30 as the currently approved emer-gency response plan. The accident analysis for on-site accidents as presented in ESG-81-30 was further reviewed and h 'now presented in the revised radiological contingency plan, RI/RD88-206, referenced above. This revision now includes the ) RI/RD89-180

s t ,j*j consequen:es of only th'e postulated accidents for the hot' cell, since the D'e r~1 Soto facility and the Nuclear Material Development Facility (Building 055) are A7 'no-longer. authorized facilities under the license. It is al:;o pertinent to mention here that since the environmental supple-ment, ESG-82-32, was i sued there has been a major organizational change in Rockwell -International with the merger of the Energy Systems Group and Rocket-dyne Division. This change has resulted in no significant effect on the pir-sonnel or programs authorized by the SNM-21 license. However, updated descrt;.- tions of the organization changes and titles have been included in revisbns to the appropriate licensing documents; viz., the health and safe m -document, ESG-82-33, and the radiological contingency plan, RI/RD88-206. i '~ v a i ,~.

II. DEMOGRAPHY <y ) Updates Section 2.0 of ESG-82-32 4 The population-distributions around the Santa Susana Field Laboratory presented'in Section 2.0 of ESG-82-32 were based on 1980' census data projected to-1985. In 1986, a new projection based on the 1980 data was developed by Urban Design Systems of Canoga Park, California. This projection included-direct observations of nearby residences and the SSFL work force, who are pre-sent only during working hours. The nearest residence-to the Hot Cell.is approximately 1 1/2 miles away, and the Rockwell working population within a radius of 1/2 mile is approximately 200. These projections of population distribution surrounding the SSFL out to distances of 5. 10, and 50 miles are shown in Figures 1, 2, and 3,-respectively. More recently, additional projections of the residential population dis-tribution have been developed based on the 1980 census and the estimated aver-age annual growth rate with some adjustments for major developments. These projections to 1989 and 1994 are presented in Tables 2 and 3 for 1989 and (/ Tables 4 and 5 for 1994.- It is noted that the Rockwell working population at SSFL has not been included in these later projections. 79 RI/RD89-180 v i 9

Ilowever, more recent data on wind speeds and stability frequencies at the Burbank airport have been obtained from the U.S. EPA Office of Radiation Programs in Las Vegas, Nevada. These data are being used currently to evalu-l ate the dispersion of atmospheric releases from the facility and estimate the { resulting general population dose attributable to the licensed operations. l The more recent data are presented here in Tables 6 and 7. Table ~6 shows i ,i the-frequencies for the=seven atmospheric stability classes for each wind di- 'I rection blowing toward the sixteen principal points of the compass. lne first two columns of Table 7 then show the frequency of the wind blowing toward each a of the sixteen directions.

e b IV. ESTIMATES OF EMISSION RATES AND CONCENTRATION val.UES iij Updates Section 3.0 of ESG 82-32 [ The emission of radioactive pollutants discharged into the atmosphere from the sources described in Section B-I of AI-76-21 is determined by contin-uous sampling and monitoring of the exhaust airstreams. The evaluation of. p radiological emissions is enhanced by the relative sensitivity of these mea-surements as compared to the measurement difficulty encountered with nonradio-E logical pollutants at equally low concentrations. A summary of radiological-emissions from the Rockwell International Hot Cell during calendar years 1986, 1987, and 1988 is presented in Table 8. These years are considered to be rep-resentative of current programs conducted at the licensed facility. Table 8.

Additionally, since natural gas is used for space heating at Rocketdyne facilities, it is necessary to consider pollutants that may be generated from that source. The amount of carbon monoxide produced by natural gas combustion in the excess-air burners used at Rocketdyne is negligible. The amount of carbon dioxide produced depends on the fuel being burned. Natural gas is rich in hydrogen in comparison with other fuels. Therefore, in excess-air combus-tion conditions where partial oxidation will not occur, all of the carbon in 2~N RI/RD89-180 /s) 17

i the gas is converted to carbon dioxide. For the natural gas supplied to. 3 3 3 f Rocketdyne,.I ft of gas burns with 2 ft of oxygen to form 1 ft of IN. carbon dioxide plus 2 ft of water vapor. From this, the annual carbon 3 L dioxide emission rate based on natural gas consumption for the Hot Cell is 6 3 t estimated to be 5 x 10 ft / year. No liquid effluents bearing radioactivity are discharged to uncontrolled areas from any of the Rocketdyne facilities. The concentration of radioactiv- ] ity in surface water for a number of sampling stations at the SSFL are given I -in the following Section V on the measurement of radioactive pollutants in = l environmental samples. l The discharge of waste water from Rockwell Internitional facilities j located at Santa Susana to uncontrolled areas is allowed under a National Pol-L lutant Discharge Elimination System (NPDES) discharge permit, No. CA0001309, a copy of which is included here as Appendix A. This specifies that grab-type samples analyzed for specified nonradioactive constituents and-for gross alpha and. beta radioactivity are to be taken prior to each discharge from a reten-tion pond. The samples are analyzed by an analytical testing laboratory cer-l Q tified by the State of California. Discharge from the retention pond of up to-3,500,000 gal / day of overflow is permitted, but only to Bell Creek. Only one r of several final retention ponds receives influent from the licensed facility. f ~ The influents include outfall from the sewage treatment plant and surface run-off water. Off-site discharge generally occurs only during and immediately following periods of heavy rainfall or during extended periods of rocket engine testing. The results of analyses for each discharge during calendar years 1986, 1987, and 1988 are presented in Tables 9,10, and ll, respectively, t 5 O RI/RDS9-180 Gl jg i _. ~, _.. _.. _, _ .x..

I V. HEASUREMENTS OF VALUES OF RADIOLOGICAL POLLUTANTS IN ENVIRONMENTAL SAMPLES b ) Soil, retention pump sediment, and surface water are sampled at on-site stations located within the boundaries of the Rocketdyne sites. Also, ambient air is continuously sampled for evaluation of long-lived radioactivity, and ambient radiation levels are monitored with thermoluminescent dosimetry. The soil sampling stations are sampled quarterly, and selected stations pertinent to the previously licensed NMDF are sampled semi-annually for plutonium. Prior to 1989, sampling stations, referred to as "off-site" stations, were located on Rockwell property and other private property adjacent to, but up to, 10 miles distant from the licensed facilities. In addition, up to 1986, vegetation samples from both the on-site and off-site stations were analyzed for radioactive content. Continuing review of the data from analysis of those samples indicated that the results of those measurements were not contributing significantly to evaluation of the environmental impact of Rock-etdyne's operations. None of the vegetation adjacent to the Rocketdyne facil-ities is involved in any food chain, and the soil and water data from the on-site stations are adequate to determine environments effects of the Rockwell I (J activities and the effectiveness of the environmental controls. The selection of sampling locations is based upon several site-specific 4 parameters such as topography, meteorology, hydrology, and the location of nuclear facilities. The prevailing wind direction for the SSFL site is gener-ally north to northwest, with some seasonal diurnal shifting to the southeast quadrant. Surface runoff waters at the SSFL site flow through several natural water courses and collect in a large capacity retention pond. This water may l be discharged off site into Bell Canyon to the south, or it may be reused for industrial purposes. The sampling station maps, shown in Figures 4 through 7, indicate that the locations provide coverage relative to diurnal wind variability with respect to the nuclear facilities and to the surface waterways.

Prior to 1984, the alpha count data had been converted to " alpha activity concentrations" by using a calibration factor derived from a thin electroplated source. This resulted in artificially low values for the alpha concentrations. For monitoring purposes, these values were acceptable, since the results were evaluated en a continuing basis for changes from previous values. RI/RD89-180 27 .. ~ ,._ _~

L A_ /

Updates Section 5.0 of ESE-82-32 L As indicated above in Section IV, the concentration of pollutants in liquid effluent releases is determined prior to liquid discharges in accord l-with the requirements in.the Rockwell National Pollution Discharge Elimination Permit, shown in Appendix A. This permit contains constituent limits for dis-charges from the SSFL site. The results of the sample analyses for specific discharges of water to Bell Canyon during calendar years 1986, 1987, and 1988 L have been presented in Tables 9.-10, and 11 in Section IV, along with compar-isons with the applicable discharge limitat 's. It is noted that there were no concentrations that exceeded the permitteo limits, and most were'signifi-cantly less than the permitted concentrations, i i

(0-Pursuant to Division 7 of the California Water Code, this California Regional Water Quality Control Board, at a public hearing held on September 17, 1984, reviewed these tentative requirements, considered all factors in the case, and adopted Orders Nos. 84-85 and 84-98 (copies attached) relative to the waste ~ discharge and to your time schedule for full compliance with requirements. The waste discharge requirements Order serves as a permit under the National Pollutant Discharge Elimination System, and expires August 10, 1989. Please note that you must file an application for a new permit at least 180 days in advance of that date. The enforcement Order expires November 30, 1986. Please'also note that changes were made on page T-2 of the Monitoring and Reporting Program. You are required to implement the new monitoring program as stated in the Monitoring and Reporting Program on the effective date of the waste discharge requirements Order. Please note'that any monitoring. report due under your previous Honitoring and Reporting Program is still required and must be submitted by the due date. Please reference all technical and monitoring reports to our Compliance file No. 6027. We would appreciate it if you would not combine other reports, such as progress or technical '(31 ) reports, with your monitoring. reports but would submit each type Y ~ (_), / of report as a separate document.
