INTRODUCTION

This report presents a summary of operator knowledge of Rocky Mountain Arsenal (RMA) structures, and is

intended to provide information for use in their remediation through implementation of the Feasibi:ity Study

Detailed Analysis of Alternatives or as part of the Interim Response Actions. Operator knowledge (i.e., records

and data pertaining to past operations in RMA facilities) will be used to assess the preliminary hazardous

nature of each structure, and to determine sampling and demolition strategies for the structures. It has been

obtained from historical information, existing sampling data, visual inspection of structures, and knowledge of

the waste stream gained through pilot-scale or treatability studies.

rasJ( 2 Dust Sampling Results of samples collected from 80 structures in South Plants in Ebesco, 195a./RiTic 87006R011965. Results reported in Task 24 Structures Survey.

raslc 24 Structures Survey Survey conduicted in 1987 that identified 982 structures On AMA, 524 Ebasco, 1998/RTIC 88306R02of which were buildings or foundations. Each was assigned one ofthe following types according to past or current use with the highestpotential for contamination: process, chemical storage, warehouse,admninistration, maintenance, utility, or laboratory. Limited samplingwas conducted. and the presence of asbestos noted.

;tructures Feasibility Study Includes consideration of fth concurrent efforts of the Expert Panel Ebasco, 1992b/RTIC 92233R0l)evalopment and Screening of on Building Sampling. Developed alternatives to include a range ofJtemnatves options, based on ARARs end structure medium type. Alternatives

were screened based on effectiv;,ness. implementability. and cost:and address the range of contaminant and structure typs expectedat RMA. These will be evaluated duinng the subsequent Detailed

Suspected asbestos was noted in the Ebasco, 19881RTIC 88306R02Structures Survey anid limited samples collected. A survey of 32 Ebasco, 1991a/RTiC 91063R0lstructures was condurcted in 1989 by Ebasco. In 1988 and 1989. OHM, 1989/RTIC 90009R04OHM conducted ar. IRA for asbestos removal under Task 5; HLA, 199lb/RTIC 91222R~labatement was conducted on 10 structures. As part of the Weston, 1992/RTI C 92 1 18RO 1Hydrazine Blending and Storage Facility IRA, asbestos wasdecontaminated prior to removal. Under Task 5, asbestos-containingmaterial was surveyed, sampled, and quantified in 486 structures, 19miles of pipe runs, and over 15,000 pipe fittings, gaskets. etc.Currently, 4. buildings in South Plants containing friable anbestosare being remediated.'

OP for Disposal of Describes proceduares for demolition end disposal of nine buildings in El Dorado Engineering. Inc..ontarninated Buildings South Plants. Procedures include identification of potential 1984RTIC 85247R12

contaminant, sampling and sample analyss, personnel protection,safety and medical, material handlings, decontamination, disposal,and monitoring. Does not include process equipment

econtaninabon of Salt In 1986, 73,909 drums containing incinerator salts and Chemically Ebasco, 1985b/RTIC 85329R0lontainer Storage Buildings neutrarized salts were transported to an off-site landfill. The salt-id Sheds container storage buildings were then dismantled, stacked, and

stored in the former Toxic Storage Yard. The soil underneath and_______________surrounding their former locations was sampled and analyzed.

-orage Tank A detailed survey of all above ground and underground storagearvey Assessment tanks at RMA (indluding those inside and under structures) was

completed in January 1992. The survey included location,operational history, integrity, current status, historical releases, andpotential for environmental impact from known or suspected leaks.The assessment included some 1,500 underground storage tanks,with some content samples collected.

a Future Use Structures Systematic composite sampling was rompleted in June 1992 for Woodward-Clyde. 1993b/RTIClot Study RMA Structures 373.3, 616, 326, 5314, 1611, and 515 to determine 93095R01

the types and concentrations of RMA target analytes potentialtypresent in structure materials. Structure matnces were sampled asmulti-alsquot composite samples representing a maximum standingmatenial volume of 500 cubic yards. The components of eachcomposite were mixed in a way that property represented thestructure. Target analytes were selected based on the chemicalhistories of the structures. TCLP extractions were conducted on altcomposite sam~ples and analyzed using EPA methods or PMPMA-certifed methods for water. Sampling results are sumiarized in thepiiot study report The reort also discusses the occupational healthand safety of demolition workers, field spike procedures and resultingdata, arnd recomrriended changes to the protocol.________________
