BURN PIT CHEMICAL PROFILE (PHASE 1 )

Reference :Bjorklund letter to Regional Water Quality Control Board, 4 March 1901(81RC02364), Re : Inactive Burning and Disposal Site ("Burn Pit" )

SUMMARY

This work plan delineates in detail how the site will be examined on a "firstpass" basis to appropriately estimate the level of effort that will be requiredfor cleanup . In addition, this presentation includes the labor estimate forthis assignment . A proposed work schedule is submitted with targeted completiondates to provide flexibility according to the chemical analysis results .

BACKGROUND

General Site History

The "Burn Pit" site was established in approximately 1958 for the safe disposalof chemical fuels by combustion in order to minimize potential public exposurewhich could result from transport across public highways to dispose in a conven-tional landfill . This site was operated by qualified Rocketdyne ProtectiveServices personnel until 1971 . At that time, the site was closed because of airpollution considerations . Since its closure, the site has been essentially in-active with the exception of a few fire department demonstrations and trainingexercises to maintain their proficiency in dealing with chemical fires andemergency incidents .

Site Descriptio n

Located in Rocketdyne's 2,400-acre Santa Susan Test Facility (SSFL) is a six-acre area which is referred to as the "Burn Pit" . Within the bounds of thesix-acre area are six pits which range in volume from approximately 200 gallonsto 10,000 gallons . Of these six pits, three of them are lined with concrete andthree unlined earthen pits . The enclosed maps give the p :'nraphic location,

topography, draining outfalls and a rough plan of the "Bu- "it" .

Area Water Run Of f

A preliminary review of the water runoff has led the Rocketdyne EnvironmentalControl Office to believe that no dischargeable hazardous residues resultedfrom the combustion processes . Routine sampling at the adjacent perimeter pondhas not shown any unusual concentrations of any of the substances required to besampled by the current NPDES permit . It is believed, therefore, that surfacerunoff is not the problem .

Ground Wate r

The Rocketdyne SSFL is serviced by one well which is maintained byRockedyne . Two additional wells are planned to be brought on line in six (6)months . None of these wells are located near the burn pit area and are upgradient .Rocketdyne believes that there has been no ground water contamination resultingfrom the past activities in the burn pit area . This conclusion is based on anevaluation of the type of the disposal practices which were employed and a 1958geologic and hydrologic survey of the underground water conditions . The study

was performed by C . C . Killingsworth, a consulting geologist from Los Angeles,whose findings revealed that "the overall average effective porosity appears tobe less than one percent (1%) over the 2,000 acres of property" . Furthermore,of the wells that have been driven or that are currently in operation, the dis-tance from the surface to reach the aquifer is in the order of 415 feet .

WORK STATEMENT

The California Department of Health Services prepared a document on "Samplersand Sampling Procedures for Hazardous Waste Streams" that offers the approachconsistent with the Burn Pit chemical profile . Thus, the attached proceduressubmit a plan of action to maximize safety of sampling personnel, minimizesampling time and cost, reduce errors in sampling, and protect the integrityof the samples after sampling .

1 . The background information about the Burn Pit has been researched and issubmitted as Table 1, ("SUMMARY OF MATERIALS AND DISPOSAL METHODS") . Recordshave been kept for years on the general pond/Later system/runoff chemicalconstituency, so that Rocketdyne's pollution control program has voluminousdocumentation on constituents that required reporting under the NPDES permitcurrently held . These records substantiate that surface runoff has been mon-

itored continually .

2. A list is attached that describes the constituents for which the analyses I li abe performed . See Table 2, ("SUMMARY OF CHEMICAL CONSTITUENT TESTS" ), that hasbeen compiled from the data assembled and tabulated as in. Table 1 .

3 . The proper samplers will be selected in accordance with the State and EPASW-846 manuals, as well as devices that are uniquely suited to the SSFL terrain .

4 . The proper sample containers and closures will be obtained using the refer-enced regulatory documents as guides .

5 . The sampling plan will include the choice of proper sampling points, andthe number and volume of the samples to be taken, including the boring depth .

6 . All proper sampling precautions will be observed .

7 . The samples will be handles properly with the appropriate chain of custodypaperwork .

WORK STATEMENT (Continued )

8 . All samples will be identified correctly and protected from tampering .

9 . All sample information will be recorded and identified in a field notebook .

10. The chain of custody record will be completed .

11 . The sample analysis request sheet will be filled out .

12 . The samples will be submitted to the appropriate laboratory .

13 . The results of the selected testing will be reviewed and decisions madewhere there are questions that need to be answered or issues resolved . If ad-ditional samples are required or further pretreatment or sample preparationnecessitated, then actions will be taken to .complete these tasks .

14 . A report will be written su,mnarizing the work performed, data generated,results found, and recommendations tendered . This report will be submitted tothe Rocketdyne Environmental Control Office as the document covering PHASE I .

DISCUSSION

The sample collection would be performed by maintenance personnel specificallyinstructed in and assigned the task by Rocketdyne Facilities and IndustrialEngineering management . A minimum of 50 samples would be obtained over thesix-acre area . The specific sampling sites would be chosen by the RocketdyneF & IE Burn Pit Project Engineer on the advice and counsel of those who haveknowledge of the area and its history and drainage patterns so that representa-tive sampling could be performed . The Rocketdyne Environmental Control Officewould approve of the sampling grid prior to the execution of the undertakingso that the historical data on past events would provide guidance and directionfor the sample handling . The choice of the chemical tests to accomplish thechemical profile of the Burn Pit area would be the responsibility of the Managerof. the Rocketdyne M & P SSFL analytical Chemistry Unit . If, in her opinion,samples were to be sent out to other laboratories, these decisions would bemade and subsequent actions taken to accommodate the best technical resolutionof the problem in the most expeditious and economical way .
