EXECUTIVE SUMMARY This Construction Completion Report (CCR) was prepared in accordance with the Remediation Design and Implementation Schedule (RDIS) Remediation Venture Office (RVO), 1999. The purpose ofa CCR is to document completion ofeach implementation project based on the Record ofDecision (ROD) forthe On-Post Operable Unit (Foster Wheeler, June 1996), and provide abasis for the U.S. Environmental Protection Agency and the Colorado Department of Public Health and Environment concurrence therewith. This CCR documents the completion of the Chemical Process-Related Activities for South Plants. TheROD project description forthis activity is Chemical Process-Related Equipment Removal (non-agent/interior). Design forthe South Plants Interior Equipment Removal was delivered to theparties in September 1997. Theproject continued the efforts thatbegan under the Chemical Process-Related Activities to the Exterior ofSouth Plants Structures, Interim Response Action (IRA) number 14. Theproject entailed the removal ofchemicals and decontamination liquids from Shell Oil Company owned and/or occupied structures within South Plants. This effort included partial removal ofpiping, tanks, and equipment. This CCR documents/summarizes the work activities involving structures, etc., as listed in the scope ofwork, andtheremoval actions taken to support those efforts. During the ongoing Chemical Process-Related Equipment Removal Activities, the process equipment that remained in Shell buildings was characterized to ensure that no materials remained in structures that wouldprevent disposal with thebuilding debris. The pipelines and equipment that remain in the buildings have been opened, drained, and ifnecessary rinsed in preparation for disposal.

0 WashingtonRocky Mountain Arsenal CCR Interior Building Chemical Related Activities for South Plants Rev. I WBS 2.02,07 - Post ROD Removal Actions for Structures September 08, 2000 1.0 INTRODUCTION This Construction Completion Report (CCR) was prepared in accordance with theRocky Mountain Arsenal Remediation Design and Implementation Schedule (RVO, November 1999). This CCR provides documentation on the completion ofa post Record ofDecision (ROD) continuance project, which originated as an Interim Remedial Action (IRA) in October 1993. This Interim Remedial Action was directed at mitigation ofcontamination sources and potential contamination sources associated with chemical production on Rocky Mountain Arsenal. Removal ofthesepipelines, associated tanks, and process equipment was incorporated into the Remedial Action called out in the ROD as completion ofequipment removal. Previous activities ofthis nature were carried out under the Chemical Process-Related Activities, Free Standing Tank Removal IRA. The Interior Building Equipment Clearance and Demolition included pipelines, tanks and associated process equipment that were used in connection with Shell production and process facilities on Rocky Mountain Arsenal. A detailed list ofequipment by building is included the "Chemical Process-Related Activities Remedial Design," hereafter referred to as theRemedial Design (File #10.060), book 1of2, Specification number 01060. This project involved cleaning andpartial demolition ofpipelines, tanks, and related process equipment located in the South Plants area. All equipment andpipelines were opened to assess the status for disposal and safety issues. Only part ofthe equipment was removed based on a case by case analysis (i.e., field conditions, size, weight, safety concerns, and/or removal effort) by the Field Manager, Task Supervisor, Safety Technician and Project Engineer. Approximately 50%ofthe equipment and piping were removed. The pipelines, tanks, and equipment that remain in the buildings were opened, drained, andrinsed with decontamination solutions, and will be demolished/removed underthe South Plants Structures Demolition and Removal Projects. This CCR describes the tasks and activities that were performed to complete the Interior Building Equipment Clearance and Demolition at the Rocky Mountain Arsenal (RMA). The project is defined in the Record ofDecision for the On-Post Operable Unit, Remediation Design and Implementation Schedule (RDIS), Appendix B, Project Descriptions in section 3.3, PostROD Removal Actions for Structures under Chemical Process-Related Equipment Removal (non-agent). The material handling procedures, waste management plan, safety plans, and contingency plans used in this continued activity were consistent withprocedures used on theprevious tank and pipeline removals. Specification 01060 ofthe design, entitled "Regulatory Requirements," was used as guidance to govern all activities associated with this task. 1.1 Site History The pipelines and associated equipment removed from the structures in South Plants, as defined inthe Scope ofWork, were used in the production and storage ofnumerous chemicals. Chemical production activities have not occurred since 1982. During shutdown activities in 1980 - 1982, the equipment used in operating processes were drained, rinsed with decontamination solutions

### and water, thendrained again. The pipelines, tanks and process equipment, were all inactive and their contents hadbeenpreviously removed. Experience has shown that the shutdown efforts were generally effective inremoving the process residues from equipment butthat small amounts ofproducts, precursors, constituents and decontamination fluids remained. Historical information indicated that process related pipelines and associated equipment were used inthe production ofvarious pesticides including, Azodrin, Phosdrin, and Vapona (organophosphate insecticides), Nudrin (carbamate insecticide), Bladex, and Planavin (herbicides). No Study Area Reports (SAR)s were associated with this project/task. 1.2 Scope ofProject / Work The scope ofwork for this project included clearing, decontamination, and decommissioning of pipelines, tanks, and associated equipment thatwere used inconnection with Shellproduction and process facilities inthe South Plants Area at theRocky Mountain Arsenal. The project involved cleaning andpartial demolition ofpipelines, tanks, andrelated process equipment located inthe South Plants area. Duringthe ongoing activities for Chemical Process-Related Equipment Removal, theprocess equipment that remained in Shellbuildings was characterized to ensure that no materials remained in structures thatwould prevent disposal with the building debris. The pipelines and equipment that remain in the buildings were opened, drained, and rinsed inpreparation for disposal as needed. The scope ofwork included clearance, and as appropriate theremoval ofprocess equipment in all South Plants structures listed in Items 1and2, Exhibit D, ofthe SettlementAgreement Between The UnitedStatesAndShell Oil CompanyConcerningYhe Rocky MountainArsenal, datedFebruary 1989. As listed inthe above referenced document, the Shell owned/controlled structures that were slated for clearance and/or removal were as follows: Item Structure No. Descriptio 2 254 Caustic Fusion Plant/Drum Storage 2 255 Fuel Oil Pump Station &2 Tank Pads 2 316 Plants Dispensary/Clinic I 316A Change House 2 347 Warehouse/Chemical Storage 2 422 HManufacture/ AldrinProduction 2 427 Meter House 2 451 Warehouse/ Production Filling 1 459 Building Used to Produce Acetylene 1 459A Lime Slurry Pumphouse 1 459B Acetylene Equipment Building

The pipelines that contained materials, such as breathable airor cooling water, were opened with fewerprecautions than unknowns or pipelines that have contained hazardous products. Pipelines that contained hazardous materials were first accessed with a closed "hot tap." This method allowed field analytical screening instruments access to the pipe through a drilled hole inside a closed unit. Only afterthe pipeline was verified as being cleared, was the interior vented to the atmosphere. Pipelines containing hazardous materials, which posed apotential hazard in place or during transport to the decontamination area, were cleaned in place using a closed re-circulation system incorporating a carbon canister to treat vent gases from the cleaning process. Rinse water from the tank, pipeline, and equipment interiors were transported to and treated by the CERCLA Waste Water Treatment Facility (WWTF).

### Otherwise, disposal ofwaste was carried out through the use ofan approved off-site waste disposal facility in accordance withMorrison Knudsen's Waste Management Program. Rinse water from areas ofstaining or from areas that were suspected ofbeing contaminated was handled similar tothe water from interiorrinses. Residues and Personal Protective Equipment (PPE) were drurnmed, and as appropriate, either stored in the on-site post90- day, storage facility or shipped to an off-site approved facility for disposal. TheMKField Manager determined the final disposition, using guidance found in the MK Waste Management Program. 1.2.2 Recyclable Materials Recyclable materials were decontaminated and handled through a salvage contract thatrequired documentation ofreclamation stating that the material was reduced to raw material. Documentation included a "Certificate ofDestruction" verifying that the identifiable equipment unit was demolished andrendered unusable. The reclamation ofthemetal by melting was documented by the Recycling Facility through a signed letter statingthe disposition ofthe material. 1.2.3 Non-Recyclable Materials Non-recyclable materials, such aspiping materials, tanks, and other process related equipment, were rinsed and leftto be disposed ofaccording to the applicable South Plants Structures Demolition and Removal Designpackage requirements. The volume ofthismaterial was minimized within the limits ofwhat canbe safely removed. 1.3 Contaminants ofConcern Unlike contaminants ofconcern formedia (air, soil, and water) the listing ofchemicals below was derived from the evaluation ofchemical process flow diagrams, process related Material Safety Data Sheets (MSDS's), and otherhistorical information and knowledge availableprior to the development oftheproject's Task Specific Health and Safety Plan (TSHSP). The purpose of theTSI-ISP listing is twofold. First itprovides information to personnel on chemicals that may be encountered, based on thehazard potential ofthe chemical or itsprobability ofbeing encountered. Secondly, the TSHSPreviews pertinent chemical hazard information and recommended exposure limits, as applicable. Below is a listing ofthose chemicals: Common Chemical Compounds 1 Acetic acid Hydrogen sulfide Acetone Methyl chloride Acetylene Methyl isobutyl ketone Ammonia Methylacetoacetamide Bicycloheptadiene Monomethylamine Brine Methyl isocyanate Carbon dioxide Monomethyl chloroacetoacetamide

### G WashingtonRocky Mountain Arsenal CCR Interior Building Chemical Related Activities forSouth Plants Rev. I WBS 2.02-07 - Post RODRemoval Actions forStructures September 08, 2000 6.0 HEALTH AND SAFETY The MK fieldpersonnel were trained to the Site Specific Health and SafetyPlan, applicable Occupational Safety and Health Administration requirements, RMA Site Health and Safety requirements, and South Plants Site Access Control procedures. Training was successfully completed and documented prior to project personnel performing any work in the field. Theproject maintained an on-site Health and Safety person during all intrusive (chemical process related) activities. Field personnel utilized continuos monitoring equipment and level "C" PPE (including the use ofan air-purifying respirator) during all intrusive activities. Approximately 15% ofthe fieldwork was performed in level "D"PPE (standard work clothes), 8 1%in level "C"PPE, and 4% in level "B" PPE (using supplied-air respiratory protection). These PPE levels were based on the criteria as set forth in the Task Specific Health and Safety Plan located in book I of2 (File #10.060) ofthe Remedial Design. A 10%bleach solution was applied to allinterior floors/walkways (horizontal surfaces) ofthe buildings prior to commencing work in each structure. This was inresponse to the large quantity ofrodent droppings and the potential presence oftheHantavirus. All decontamination liquids were contained within the buildings. Large rodent nests were removed using a Hepa-Vac. All work pertaining to eliminating the Hantavirus was performed in level "C" PPE. MK maintained and controlled limited access to the work sites as well as "Hot Zone" work areas within the work site during intrusive activities. HotZone work areas were established in areas where respiratory and protective clothing were required, intrusive activities were being performed, and the potential for contact or exposure to chemicals existed. Decontamination facilities were established and maintained forboth personnel and equipment at building location as an integral part ofthe building Contamination Reduction Zone (CRZ). 6.1 Project Health and Safety Procedures Before work started at any one site, a Tailgate Safety meeting addressing the history ofthe site, evacuation routes, and safety concerns inherent to the site was performed with all field personnel. Prior to the beginning offield activities foreach day, a Tailgate'Safety meeting was held and documented, addressing the specific safety concerns forfield activities forthe day (File 418.072). Material discussed during these meetings included, but was not limited to: building history and use, chemical Material Safety Data Sheet (MSDS) reviews, potential for chemical contact, and Personal Protective Equipment (PPE) requirements. Additionally, a MK site wide safety meeting was held on a weekly basis. Documentation forthese meetings are retained and maintained by the MK Site Health and Safety Officer (building 132 ofthe RMA). A Job Safety Analysis (JSA) and Engineering Structural Report was performed on each building in whichwork was performed (File # 21.200). These reports provided information as to the integrity and safety concerns associated with an individual building, andprovided workers with the safety items requiring remedy priorto commencing work. Daily equipment inspections were performed and documented (File # 27.101).

6.2 Summary ofHealth & Safety Results Localized air monitoring was performed during all intrusive activities. Equipment, tanks, and piping interiors were monitored for hazardous conditions, including LEL, H2S, 02, Co, and VOC's. In addition, freon detectors were utilized to address the presence offreon in air conditioners andmercury vapor analyzers were used on mercury containing equipment/instruments. Additionally, liquids were checked forpH and oils for PCB's. A closed monitoring and draining system (Hot Tap System) was utilized during the initial opening of piping,and equipment to prevent personnel and atmospheric exposure, utilizing a nitrogen purge should levels exceed 10% LEL.Utilizing the Hot Tap System provided 100%control ofthe equipment and piping waste contents. No spills, releases, or exposures occurred during the project. Theproject was completed with no lost time injuries and only one recordable injury. The recordable injury resulted in three stitches to an employee's index finger. The incident occurred whilethe employee was stacking barricades for site control.
7.0 ENVIRONMENTAL AND ROD COMPLIANCE The Shell/MK InteriorBuilding Chemical Process Related Activities for South Plants project wasperformed is such a manner as toprotect human health and the environment and in compliance with ARAR's, project plans and design specifications. 7.1 Air / Odor Monitoring Results Air monitoring was conducted in several buildings ofconcern to establish ifany potential breathing hazards existed prior to the commencing ofany intrusive activities. Laboratory results ftomthe Sunima Canister Sampling did not find any elevated chemical hazards that would pose abreathing hazard to personal health. 7.2 Stormwater Management No Storrnwater Management plan was anticipated for theinside ofthe buildings. However, Stormwater did migrate into building 514 and 514A. This Stormwater was pumped and transferred to the CERCLA WWTF for treatment. CERCLA WWTF took the samples ofthe transferred water and also maintained the laboratory results forthose samples. Stormwater as well as water from equipment decon, wastransferred and logged in at the CERCLA WWTF. These logs were copied and are apart oftheproject files (File #18.910).

### V. Review QAJQC QA/QC requirements werereviewed and are as follows:

- QArequirements include documentation thattankshave been destroyed andthatpiping and other materials are recycled/reclaimed toraw material. (i.e. Certificate ofDestruction/Reclamation viathe metals recycling firms)

- QC activities were governed byfield actions which involved the completion ofdaily reports, daily logbook entries, check list andother forms ofdocumentation usedto track the decommissioned materials (equipment, tanks, andpiping) and thewashing ofthese materials which were removed for salvage/recycling purposes.

- Waste Management ofwaste materials which were captured/removed during decommissioning were stored in approved containers and handled/managed according to the Shell/MK Waste Management Program/Plan (WMP). Once waste materials were turned overto the MK Waste Management group, the storage and/or disposal ofthe materials was coveredunder the WMPwhich has been formally audited both internally (MK,ARMY ECAS) andexternally (Both EPA &State). QA/QC ofthe Shell/MK VVMP at theArsenal is separate from the South Plants equipment andpiping task, andmeets therequirements of CERCLA regulations and is in substantive compliance with RCRA. Requiations. VI.
