LETF ReleasesLocation : Laser Engineering Test Facility (LETF)Date: 3 March 1983Substance : Fluo rides

During a regular discharge water analysis on 3 March 1983, fluorides exceeding legallimits of 1 ppm were discovered in both the Bowl Area (R-1) and Pe ri meter Pond reservoirs. Thesamples taken indicated fluori de levels of 18 ppm at R-1 and 8 ppm at the Perimeter Pond. Uponreceipt of these reports, underdrains at both reservoirs were closed . However, rainfall continuedto cause an involunta ry discharge from Pe ri meter Pond that could not be stopped until noon on 6March 1983 . A water sample taken for fluo ri de contamination at downstream of the Rocketdynesampling points immediately following the discharge on 3 March at 3:00 p.m . was only 1 .6 ppm .Since the level at Pe ri meter Pond was lower than R-1 and Pe ri meter Pond was downstream, it wasassumed that the reading never exceeded 1 .6 ppm . The source of the fluorides was found to bethe LETF fluo ri ne sump. The sump was a concrete tank which contained approximately 20,000gallons of aqueous solution. The sump has since been removed with the approval of the DOHS .The sample analysis revealed a fluo ri de concentration of 5900 ppm . Other constituents in thesolution are NaOH and water . A subsequent investigation found that approximately 8000 gallonsof the fluo ri de solution had been discharged from the scrubber sump . The discharge was due toan error on the part of an engineer which resulted in releasing the solution into the SSFL reclaimwater system .

BNA0401115 6HDMSe00206537

Location : Area I LETF Scrubber Pon dDate: 14 May 198 1Substance: Fluorides

On the evening of 14 May 1981 , a hose was left unattended while the scrubber sumpwater level was being replenished . This situation continued for a pe riod of 16 hours and resultedin the release of approximately 400 pounds of sodium fluo ri de from the LETF hazardous wast epond . The release was contained in the R-1 reservoir of the SSFL water reclamation system . As aresult of containing the fluo ride release , the fluo ri de concentration in the pond increased to 1 3ppm. The water could not be discharged under the NPDES permit because of the high fluo ri d elevel . Therefore , Rocketdyne obtained permission from the RWQCB and the DOHS to spray th ehillsides with the fluoride - containing water. This deposited the excess fluo ride into the soils unti lthe winter when rainfall diluted the fluo ride sails and returned them to the ponds within discharg elimits .

Sewage Treatment Plant III IncidentLocation : Area III sewage Treatment Plant, near STL-I VDate: 11 January 1989Substance : Pa rtially treated sewage wate r

Approximately 50 gallons of partially treated sewage water was released at the SSFL Are aIII Sewage Treatment Plant. The source of the release was an ove rflow line leading from th etertia ry filter system to the adjoining ove rflow containment. At the point of contact between thetertiary system and the overflow line, two bolts were not in place thereby allowing for sewage wate rto flow through the two bolt openings to the concrete below and to an adjoining termed area .Most of the overflow, however, went through the overflow line while a minor amount flowe dthrough the two bolt openings . Bolts were installed on 12 January, thereby preventin grecurrence of sewage water release .

EEguinment Laboratory (B/301 )Location : Equipment Laboratory, B1301, Area IDate : 28 January 1987Substance : 1,1,1-Trichloroethane (TRIC )

Du ri ng operation of the TRIC distillation equipment at the Equipment Lab, a systemmalfunction caused 175 gallons of TRIC to discharge into the containment basin . The TRIGflowed through the drain valve of the containment basin and across the adjacent asphalt roadway.The TRIC pooled on the roadway and dissolved the hydrocarbon binders of the asphalt , softeningand damaging app roximately 200 square feet of the roadway . The malfunction of the TRIOdistillation equipment was att ri buted to a loss of 150 psi GN2 pressure which allowed apneumatically operated shutoff valve to close . Closure of the valve terminated the flow ofTRICfrom the distillation unit to the storage tank. As a resu lt, TRIG backed up in the water separator unitand flowed out the ove rflow One into the containment basin. The loss of TRIG outside thecontainment basin was a ttributed to the containment basin drain valve being left in the openposition. Had the valve been closed , the discharge would have been confined to thecontainment basin .

The residual TRIC and contaminated asphalt and soil were removed . The roadway wasrepaired with new asphalt. A total of 821 gallons of solvent and wastewater was collected andtransported to OSC for recycling . A total of eight cubic yards of affected asphalt and soils weretransported to Casmalia Landfill . The lab analytical results on three soil samples taken in theaffected area shown the concentrations of TCA remaining in the soil to be insignificant .Additionally, the ove rflow pipe where the valve failed has been replumbedto a TCA storage tanThe containment basin drain valve was chained and locked in the closed position .

Surface Impoundment sThere are five surface impoundments located in Areas I and Ili at theSSFL. All Su rfaceImpoundments are included in the Part A Application for CAD 093365435 . Closure activities are

complete . A closure report has been submitted for approval to the DOHS in September 1989 .Post closure care for the surface impoundments involves routine monitoring and sampling o fsurface runoff and groundwater remediation . For sample analysis please refer to the ClosurePlans and Closure Report submitted to the Department .

ECLThe ECL surface impoundment is located in Area Ill at the Enginee ri ng Chemistry

Laboratory and has not been in use since September 1984 . The surface impoundment wa sgunite lined and used for temporary waste storage. Waste chemicals stored in this impoundmentinclude inorganic salts, mainly fluoride salts, and organic solvents such asTCE. In October 1984 ,Rocketdyne removed the liquid in the pond and the pond liner. The liquid, liner materials, an dsurrounding soils and sandstone were transported to a Class I disposal facility under unifor mhazardous waste manifest . Closure activities included diversion channel construction, surfacewater removal, defoliate interior of impoundment, install a standpipe, install and compact backfill ,install concrete pad, and construct agunite rainwater by pass channel . Soil sampling in Decembe r1984 indicated that additional excavation was not necessary . All closure activities were completedby August 1, 1989 .

STL-IV-1The surface impoundment STL-IV-1 is located at the test area STL-lV located in SSF L

Area III . This impoundment was lined and used for collection of cooling water, aspiration water,area wash-down water and site runoff. Chemical contaminants are monomethylhydrazine,nitrogen tetroxide, nitric acid, and alcohol . It has been inactive since November 1985. Closureactivities were completed in 1988 . Closure steps taken included concrete liner sampling,diversion channel construction, surface water removal, gunite liner removal, backfilling with cleannative soil and construction of a concrete slab over the filled impoundment area .

STL-IV-2The STL-lV-2 su rface impoundment located at the test area STL -IV was unlined and has

been inactive since November 1985 . The impoundment was used for collection of cooling water,aspiration water , area washdown water and site run-off . Potential chemical contamination includesmonomethylhydrazine, nitrogen tetroxide , nit ric acid , and alcohol . Surface water did co ll ect in theimpoundment during the inactive period because of its location in a natural drainage channel . Theimpoundment was allowed to dry out p rior to initiating the closure procedures . Closure activitiesincluded diversion channel construction , su rface water removal , defoliation of the inte ri or ofimpoundment , backfillwith clean native soil , construction of a gunite rainwater bypass channel,and install vegetated topsoil . Closure activities were completed in February 1989 .

APTF-1 and - 2There are two inactive surface impoundments located at the Advanced Propellants Test

Facility located in Area I of the SSFL . These impoundments were concrete lined and used forretention and treatment of potentially contaminated water . These su rf ace impoundments havenot been used since November of 1985 . The surface impoundments were located in naturaldrainage areas, allowing surface water to collect in the impoundments . The impoundments wereinspected weekly p rior to closure , and samples were collected when water existed in theimpoundments . The impoundments last contained water on 25 May 1985 and samples werecollected . The impoundments were then pumped out and the water discharged to a naturaldrainage channel which, in turn , drained to the SSFL reclaimed water system . The ponds werethen allowed to dry out pri or to initiating closure activities . Closure activities included linersampling , diversion channel construction, surface water removal , gunite liner removal, andbackfilling with clean native soil . A concrete slab was constructed over APTF-1 surfaceimpoundment, completing closure activities in December 1988 . Six inch vegetated topsoil wasinstalled at APTF-2 surface impoundment along with a gunite rainwater bypass channel,completing closure activities in Februa ry 1989 .

In regard to the prior releases described in Number 3above, please provide (for each unit) an yanalytical data that may be available which would desc ribe the nature and extent of environmenta lcontamination that exists as a result of such releases . Please focus on concentrations ofhazardous wastes or constituents present in contaminated soil or groundwater .

Sewage Treatment Plant III Inciden tThe spill described in section 2 at the Area III sewage treatment plant was contained in th e

bermed overflow area and there were no releases to the SSFL water system.

LETF ReleasesThe LETF fluorine sump was the source for two accidental releases of fluorides into the

SSFL water system . Refer to section 2 for desc riptions of the incidents . Enclosed are sampleresults relating to the previously desc ri bed accidental releases (Enclosures 3 and 4)

Surface Impoundment/Groundwater Remediatio nThe past use of trichloroethylene and associated solvents for the cleaning of rocket

engines resulted in groundwater contamination at SSFL. The Hydrogeological AssessmentReport ( HAR), submi tted to the Depa rt ment , extensively characterized groundwatercontamination . Rocket engine testing operations were conducted at the Alfa , Bravo , Coca, andDelta areas of SSFL beginning in 1953 . TGE was used to clean the thrust chambers of the rocketengines after each test. From approximately 1953 until 1961, approximately 4,000 engine testswere conducted at Area I and Area Ill of SSFL . Although most of the engine testing wasconducted prior to 1962, extensive engine testing operations occurred during 1975-1977,resulting in additional TCE releases . Other releases of TCE have occurred from spills of thesolvent during the pe riod the solvent was used at the test facility .

Histori cally , waste TCE and non-contact cooling waters from the rocket testing activitieswere discharged to retention basins at SSFL . TCE previously channeled to the water retentionbasins percolated into the ground and resulted in the groundwater contamination . Sample resultscollected from groundwater monito ri ng wells indicate TCE concentrations up to 2400 ug/l .

5. Describe the approximate dates and locations of product spills and releases which haveoccurred or are recurring at your facility and any cleanup operations which have occurred relativeto these incidents .

Area I Gasoline Tank ReleaseLocation: Area I GasolineTank, near Building 300 .Date: 10 June 1987Substance : Unleaded Gasoline

Eight hundred gallons of unleaded gasoline was released to the environment duringPetro-rite testing of a new tank installation in the Area I portion ofSSFL. The leak occurred whengasoline was being added to the tank so that the tank integrity test could take place . As a result ofa loose coupling att aching the tank with asso ci ated piping , 800 gallons was lost into the gravelsurrounding the new tank p rior to being discovered . The tank was removed under the directionand superv ision of the Ventura County Health Department . Also removed was approximately 400cubic yards of di rt and gravel to a depth of 23 feet where hard sandstone was encountered .

The fuels padcontains monomethylhydrazine at this time . The oxidizer pad contains nitrogentetroxide in 500gallon containers and various propellants used for R&D . The propellants include chlorinepentafluoride, hydrogen fluoride, fluorine, and others . The two separate pads are concrete,however, no spill containment is available since the surface impoundments have been closed . Aplan to install spill containment is in work .

Wastewater Treatment UnitsSewage Treatment Plant (B/515)

This is an inactive sewage treatment plant, last used in 1987 . The plant is located in thenorth-central section of Area Il . This sewage treatment plant is a small package activated sludgeplant which received an average flow of approximately 4,000 gallons per day from the Area 11portion of SSFL. The design capacity of the plant is 50,000 gallons per day. The facility consistsof a comminutator, source aeration unit, clarifier and chlorine contact chamber . The wastewaterreceived here consisted of both sanitary sewage and cooling water discharges . The secondaryeffluent from the plant is discharged to a drainage ditch which conveys the treated water to theSilvernale Reservoir.

Other Waste Handling AreasWater Reclamation Syste m

A water reclamation system consists of retention ponds, skim ponds, and reservoirslocated throughout SSFL. SSFL discharges intermittently up to 160 million gallons per day (mgd)of water to the reclamation system . The system receives discharges from several sources at SSFLincluding surface water runoff, non-contact cooling water from rocket engine testing, and effluentfrom the sewage treatment plant located in Areas hand Il l . In general, water is not discharged off-site from SSFL's water reclamation system because the water is reused for rocket engine testingoperations . However, during periods of high precipitation when the water storage capacity of thereclamation system is exceeded, excess water is discharged to either of two outfalls located onthe southern section of SSFL. All discharges are sampled prior to release and are regulatedunder SSFL's NPDES permit .

Area II LOX PiantA small liquid oxygen production plant used in the 1950s and 1960s . It has been inactive

since then. There are unknown sump areas and possible petroleum hydrocarbon soilcontamination .

containment for the Propellant Load Facility which uses monomethyihydrazine and nitrogentetroxide under an Air Force contract . No spills to the impoundment ever occurred, and the onlydischarges to the impoundment have been rainwater . Closure activities were complete in July1987. A closure report was submitted in September 1989 .

DeltaThe Delta surface impoundment was an earthen pond used for retention of noncontact

cooling water associated with rocket engine test firings at the Delta Test Stand . The primarycontaminants in the surface impoundment were TCE and associated solvents and propellants,mainly monomethyihydrazine, used as part of engine testing . The only discharges to the

Please focus on concentrations ofhazardous wastes or constituents present in contaminated soil or groundwater.

Ground Water Contaminatio nThe past use of tnchlo roethylene and associated solvents for the cleaning of rocket

engines resulted in groundwater contamination at SSFL . The Hydrogeological AssessmentRepo rt (HAR), submitted to the Department , extensively characte ri zed groundwatercontamination. Rocket engine testing operations were conducted at the Alfa, Bravo , Coca, andDelta areas of SSFL beginning in 1953 . TCE was used to clean the thrust chambers of the rocketengines after each test . From approximately 1953 until 1961 , approximately 4,000 engine testswere conducted at Area II of SSFL . Although most of the engine testing was conducted p rior to1962, extensive engine testing operations occurred du ri ng 1975-1977, resulting in additionalTCE releases. Also other releases of TCE have occurred from spills of the solvent du ri ng theentire pe ri od the solvent was used at the test fa ci lity .

Historically, waste TCE and non-contact cooling waters from the rocket testing activitieswere discharged to retention basins at SSFL. TCE previously channeled to the water retentionbasins percolated into the ground and resulted in the groundwater contamination . Sample resultscollected from groundwater monitoring wells indicate TCE concentrations up to 2400 ug/l .

Ma-Bravo Test Area sThe following reportable spills occurred at the Alfa and Bravo Test Areas :

Location : Alfa-3 Test Stand TCE tan kDate : 3 Jan 1983Substance: Trichioroethylene

Two thousand gallons of TCE had leaked from the Alfa-3 TCE storage tank because th etygon sight gauge had broken its lower connection and the hand valve feeding the gauge wa sopen. As a result, the TCE leaked from the tank into the trench and pipe system which deposite dthe material on the Alfa-3 concrete spillway

The hand valve was closed when the leak was discovered and a new sight gauge wasinstalled . The TCE which had not evaporated was collected in drums for reclamation . The spill di dnot reach the SSFL water system. The Regional Water Quality Control Board (RWQCB) and th eVentura County Air Pollution Contro l Dist ri ct (VAPCD) were notified of the spill .

Location : TOE Reclaim Tank, Alfa Test StandDate: 12 August 198 3Substance: Trichioroethylene

A leak was noticed at the top of the TCE Reclaim Tank . The tank storage capacity was atits maximum and TCE from engine flushing was causing the tank to overflow . The spilled TCEflowed into a concrete lined spillway that is inactive and dammed off, preventing any flow into thegeneral water system . An estimated 285 .325 gallons of TCE were spilled from overfilling thetank. The VAPCD and RWQCB were notified of the spill .
