Administrative ACM Removal Project CCR Rev4Rocky Mountain Arsenal Report Project: Revision 4 Administrative ACM Removal January 14, 2003 EXECUTIVE SUMMARY

The purpose of this Construction Completion Report (CCR) is to document completion of Asbestos Containing Material (ACM) Removal Projects in occupied administrative buildings at Rocky Mountain Arsenal (RMA). The ACM Removal Projects covered inthis CCR are the: Building III Stairwell, Class 11 - Non Friable; Building 383, Class 11 - Non Friable; and Building 618, Class Iand II - Friable and Non-Friable ACM. Many ACM Removal projects in non-administrative buildings were completed before the signing ofthe On-Post ROD under Interim Response Action (IRA) K. These projects are documented in the IRA-K Summary Report. The subject ACM Removal Projects and site-wide remedial projects identified by, and completed after the signing ofthe Onand Off- Post RODs, are documented in Construction Completion Reports.
The subject buildings were located in the administrative sections ofthe RMA (see Figure 1). Buildings III was used for administration purposes and Building 383 was used as the military Post's Officer's Club and later as a U.S. Fish and Wildlife Service (USFWS) Visitor's Center. Building 618 was used as administrative space in the south end ofthe building, as a Chemical Military Protective Suit Washing Facility in the west end ofthe building, and the remainder of the building was used as a warehouse to store RMA supplies. Through surveys and sampling it was determined that Building III Stairwells and Building 383 contained floor tile that were made with non friable ACM and Building 618 had friable and non friable ACM on the interior roof and pipes above the Self Service Supply Store which was constructed within the exterior walls of Building 618. The Contaminants of Concern (COC) for all three projects were determined to be ACM. No chemical contamination of the ACM was found and was not suspected since the ACM was in administrative areas and on non-process piping. ACM removal at the above listed sites involved preparation of project workplans and safety plans, background ACM level monitoring, construction of negative air containments where needed, removal ofACM, airmonitoring for ACM during and after removal, and proper disposal ofthe ACM and protective equipment along with preparation ofrequired project documentation. For each ofthe 3 projects, air monitoring ofairborne ACM levels was conducted to determine background levels, levels during ACM removal and airborne ACM levels after removal work was completed in compliance with all applicable regulations including 40 CFR 763 Part M. Final Clearance samples were analyzed using Transmission Electron Microscopy (TEM) Analysis. All samples did not exceed applicable federal and state regulatory requirements. Final Clearance TEM sample results are included as Figure 2, 3, and 4 for Buildings 111, 383 and 618, respectively. ACM Removal was carried out by trained and certified Department ofArmy personnel for the Building III and Building 383 projects, and by a single Contractor, Aguirre Engineers, Inc., for the Building 618 project. QualityAssurance, airmonitoring and project control was provided by trained and certified Department ofArmy personnel for all 3 projects.

### 1.0 INTRODUCTION

The Building III Stairwell, Building 618 and Building 383 ACM Removal Projects were completed after the signing of the Off-Post and On-Post Record of Decisions, and involved removal ofthe following classifications ofACM: " Building III Stairwell: Class 11 - NonFriable, about454 sqft. offloor tileand mastic " Building 383: Class 11- Non Friable,about 275 sqft. offloortile andmastic " Building 618: ClassIandII - Friable andNon-Friable, about 1250 sqft. offloortile and mastic, 1,020 sqft. of1"x 6"wood decking and 100 lineal feet ofairreturnducting contaminated withACM ACM removal at the above listed sites involved preparation ofproject workplans and safety plans, background ACM level monitoring, construction of negative air containments where needed, removal ofACM, airmonitoring forACM during and afterremoval, and proper disposal oftheACM andprotective equipmentalong withpreparation ofrequired projectdocumentation. ACM Removal was carried out by trained and certified Department ofArmy personnel for the Building I11 and Building 383 projects, and by a single Contractor, Aguirre Engineers, Inc. for the Building 618 project. Quality Assurance, airmonitoring and projectcontrol wasprovided by trained andcertified Department ofArmypersonnel for all3projects.

1.1 Site History
The subject buildings were located in the administrative sections ofthe RMA (see Figure 1). Buildings I11 was used for administration purposes and Building 383 was used as the Military Post's Officer's Club and later as a U.S. Fish and Wildlife Service (USFWS) Visitor's Center. Building 618 was used as administrative space in the south end ofthe building, as a Chemical Military Protective Suit Washing Facility and SelfService Supply Store in the west end ofthe building, and the remainder ofthe building was used as a warehouse to store RMA supplies. Through surveys and sampling itwas determined that Building I11 Stairwells and Building 383 contained floor tile thatwere made with nonfriable ACM and Building 618 had friable and nonfriable ACM on the interior roof and pipes of the Self Service Supply Store which 

### was constructed withinthe exteriorwalls ofBuilding 618.

### 1.2 Scope ofProjects

ACM removal at the below listed sites involved preparation of project workplans and safety plans, background ACM level monitoring, construction of negative air containments where needed, removal ofACM, air monitoring ofACM during and after removal, and proper disposal ofthe ACM and protective clothing used during removal along with preparation of required project documentation. The ACM that wasremoved in Buildings 111 and 383 were floortilethat contained low levels of non-friable ACM. The floor tile removed in Building I11 was in the East, West and Central wing stairwells. The floor tile removed 

### in Building 383 was inthe men's and women's bathroom area. The ACM that was removed in Building 618 consisted offriable and non-friable ACM pipe insulation that in some cases had fallen onto the roof structure ofthe Self Service Supply Store builtwithin the exterior walls ofbuilding 618. ACM Removal was carried out by trained and certified Department ofArmy personnel for the Building IIIand Building 383 projects, and by a single Contractor, Aguirre Engineers, Inc. for the Building 618 project. QualityAssurance, air monitoring andproject control was provided by trained and certified Department ofArmypersonnel for all 3projects. The O&M ACM Removal Projects involved removal ofthe following classifications ofACM: " Building I11 Stairwell: Class 11 - Non Friable, about454 sqft. offloor tile andmastic " Building 383: Class 11-Non Friable, about 275 sqft. offloortile and mastic " Building 618: Class IandII - Friable and Non-Friable, about 1250 sqft. offloortile and mastic, 1,020 sqft. of 1 "x 6"wood decking and 100 lineal feet ofairreturn ducting contaminated with ACM

1.3 Contaminants ofConcern The Contaminants of Concern (COC) for all three projects were determined to be ACM. No chemical contamination ofthe ACM was found and was not suspected since the ACM was in administrative areas andon non-process piping.

1.4 Air Monitoring and Final Clearance Confirmatory Sampling For each ofthe 3 projects, air monitoring ofairborne ACM levels was conducted to determine background levels, levels during ACM removal and airborne ACM levels after removal work was completed in compliance with all applicable regulations including 40 CFR 763 Part M. Final Clearance samples were analyzed using Transmission Electron Microscopy (TEM) Analysis. All samples didnot exceed applicable federal and state regulatory requirements. Final Clearance TEM sample results are included as Figure 2, 3,and 4 forBuildings I11, 383 and 618, respectively.

### 3.0 REMEDIATION GOALS, STANDARDS AND CRITERIA In general, remediation goals for ACM removal projects involve removing ACM material and containing the release of ACM to the environment. This is accomplished through the construction ofnegative air pressure containment systems around the work zone where ACM removal will take place, by filtering the air asit isremoved fromthe work zone and filtering the waterthat drains fromthe workzone toremove particles ofACM.

3.1 Air Emissions Control For each ofthe 3projects, air monitoring ofairborne ACM levels was conducted to determine background levels before removal begins, levels ofairborne ACM during ACM removal and levels afterremoval workwas completed in compliance with all applicable regulations including 40 CFR 763 Part M. Final Clearance samples were analyzed using Transmission Electron Microscopy (TEM) analysis. All samples did not exceed applicable federal and state regulatory requirements. Final Clearance TEM sample results are included as Figure 2, 3, and 4 for Buildings I11, 3 83 and 618, respectively. 3.2 Design Criteria The ACM removal project design criteria are listed in the applicable federal and state regulations, and are further described in the project's scope ofwork, workplans and site specific safety andhealth plans.

4.0 DESCRIPTION OF CONSTRUCTION ACTIVITIES AND PROJECT MODIFICATIONS
4.1 Construction Activities 4.1.1 Pre-remediation Activities Pre-remediation activities for all three projects included background high volume air sampling and analysis ofsamples to determine the level ofACM in the air in the area where the ACM is located. Negative air pressure containment systems are constructed which consist ofplastic

### sheeting and support structuresthatare sealed tobe airtightwith ducttape around allpipes or other structures thatenter the work zone where ACM removal willtake place. Negative pressure is maintained inthe work zone continuously after ACM removal hasbegun by usingHigh Efficiency Particle Accumulating (HEPA) Filter airpumping equipment thatmaintains negative air pressure andfilters ACMparticles outofthe airbefore it leaves the containment structure. A decontamination zone was constructed at the entrance tothe containment structure toallow workers who enter the containment to suit up inappropriate personnel protective clothing andto decontaminate themselves before leaving.the containment structure. 4.1.2 ACM Removal When friable ACM was being removed, wetremoval methods were utilized by wetting theACM before removing it andplacing it indisposal containers. Whennon-friable ACM was removed, wetremoval methods were notalways employed. Continuous airmonitoring ofairborne ACM levels inside the containment was conducted to ensure the levels didnot exceed worker standards setbythe National Institute ofSafety and Health (NIOSH). After ACMremoval work was completed, final clearance air sampling was conducted insidethe containment to ensure the ACM levels were below applicable federal and state standards. Once the samples were analyzed using TEM analysis techniques andthe levels ofACM werebelow applicable requirements, then thenegative air containment structure would be dismantled, put into disposal containers, sealed, labeled and consolidated for disposal. 4.1.3 Disposal ACM, Personnel Protection Equipment (PPE)andACM contaminated containment structures or other material wereproperly bagged, sealed, labeled andmanifested before they were disposed ofatappropriate landfills. Non-friable ACM generated from Buildings IIIand 383 in February &March 1998 was stored in Building 732 inSouth Plants, latermovedto Building 742 on December 12, 1999, and storedthere until itsultimate disposal inRMA's on-site landfill. Friable andnon-friable ACM generated from Building 618was shipped and disposed ofoff-site at the CSI Landfill onApril 21, 2000 (Non-Hazardous Waste manifest# 185660). Manifests are maintained at RMA Transportation Office IAW RCRA requirements. 5.0 ACM REMOVAL QUALITY ASSURANCE/QUALITY CONTROL
5.1 QA/QC Procedures All ACM Removal Work at RMA was overseen by field inspectors that ensured contractors and in-house staff conducted the work in IAW all applicable federal and state standards and regulations. Daily inspections ofACM removal work procedures, negative air containments, decontamination procedures, safety measures, project documentation and air monitoring implementation were conducted and documented. 5.2 Summary ofQA/QC Documentation Inspection forms, checklists, air monitoring results and photographs of work practices were prepared and are contained in project books for each of the projects. These documents are maintained in the RMAAdministrative Record Facility.
