Subject: Hazardous Materials Building Survey Navy Medical Research Unit-6 Building # 2 Lima, Peru FCG Project Code: SS&A-05

Dear Mr. Phillips:

FCG Environmental (FCG) completed a hazardous materials building survey of Building 2 located at the Navy Medical Research Unit-6 (NAMRU-6) facility in Lima, Peru. This included asbestos bulk sampling and lead-based paint testing to define possible hazardous materials issues at the site. The investigation was performed from June 16 - 19, 2015 by William Miller, a CA Certified Site Surveillance Technician (No. 07-4160) and CA Certified Lead Inspector/Assessor (No. 17274); under the supervision of Alan Forbess, CA Certified Asbestos Consultant (No. 94-1549) and Certified Lead Inspector/Assessor (No. 17425). This report documents the findings of our hazardous materials survey, which was conducted as part of a Facilities Utilization Study and possible renovations to the subject site.

1.0 Background Information / Scope of Project

Background: The subject site is a medical research facility located in Lima, Peru which is hosted by the Peruvian Navy and located at their flagship hospital. The Naval Medical Research Unit-6 conducts research on and surveillance of a wide range of infectious diseases in the South America. NAMRU-6 partners with the Peruvian Army and Navy and works closely with prestigious local universities and the Ministry of Health. NAMRU-6 collaborates with USAID, U.S. CDC, U.S. NIH, PAHO, and a number of American universities. These partnerships yield a research agenda that includes prevention strategies, clinical management and trials, chemotherapeutics, immuno- and molecular rapid diagnostics, epidemiology, and ecology as well as social and economic impact.

The scope of work for the overall project is to study the feasibility and costs associated with the modernization and re-capitalization of Building 2 at the NAMRU-6 site. Included in the scope of work is a Facility Utilization Study, Deficiency Tabulation, Economic Analysis, Concept of Operations, preparation of DD1391(s) for special projects with option for DD1391(s) for MILCON and a Project Book (Optional). The hazardous materials building survey was included in the scope of work as part of the Engineering Services section, with the results and estimated costs for removing or encapsulating the hazardous materials to be included in the cost of the projects and included in the DD 1391 documentation (Parametric Cost Estimate).

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 2

Scope of Hazardous Materials Survey: The following services were conducted in order to define hazardous materials concerns at the subject site:

A visual inspection of representative interior and exterior building materials was conducted to identify suspect asbestos containing materials, lead paint or lead components within the areas leased or occupied by the NAMRU-6 operations.

Bulk samples were collected from suspect asbestos containing materials for submittal to a qualified laboratory for analysis. All bulk samples were analyzed by Forensic Analytical, a certified laboratory located in Rancho Dominguez, CA. All samples were analyzed by polarized light microscopy (PLM), to determine asbestos fiber concentrations in bulk building material samples. PLM is applicable for the analysis of building survey submissions and other bulk materials.

A survey for lead-based paint was conducted through the collection and analysis of paint chip or bulk samples from representative surfaces and materials throughout the leased areas. All samples were analyzed by EPA Method 3050B/7420 for total lead.

General observations and inspection of fluorescent light fixtures, switches, transformers and similar items of potential hazardous materials content were included in this survey.

We did not include inspection or inventory of laboratory chemicals, reagents or other compounds that are part of the laboratories or overall site operations and not part of the structure or proposed renovations.

All field observations, laboratory analytical data and other findings have been evaluated, with this written report summarizing our findings and providing recommendations as necessary.

2.0 Asbestos Survey Findings

Site Description: The subject site includes a 2-story commercial building (Building 2) on facility operated by the Peruvian Navy. Building 2 is a two-story structure with a partial basement. The building has two floors with animal storage and testing facilities, offices and a laboratory on the first floor and offices and a conference room on the second floor. The basement houses the Facilities Department and maintenance area, offices and an exercise gym. There is a small attached warehouse on the first floor elevation. FCG was asked to perform a survey of representative building materials in building 2 and the adjacent incinerator area that might be disturbed as part of future renovation activities in order to identify hazardous materials issues.

Materials of Construction: Building materials found at the subject site includes concrete and clay tile structures surfaced with a cement plaster finish with concrete roof deck and concrete slab foundation. Exterior walls are covered in faux red brick or rough textured cement plaster.

Drywall was found in the basement gym and the second floor offices. Most of the office areas feature suspended T-bar ceilings with acoustic tiles. The animal areas feature T-bar ceiling with aluminum ceiling tiles or hard lid ceilings. Flooring throughout all areas is primarily finished with ceramic tiles adhered using cement mortar over concrete subfloor. Interior walls are painted plaster, drywall or concrete. Ceramic wall tiles were found in the basement maintenance shop, first floor clean room and dirty room, first floor restrooms and the second floor restrooms and kitchen break room. The roof of the main building is covered by clay tiles over a soil layer on a concrete deck. The warehouse has a roofing system which features corrugated cement panels (suspect asbestos or “Transite”).

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 3

HVAC units are roof mounted with exterior metal ducting, and interior metal or flex ducting.

HVAC ducting is insulated with fiberglass covered with rubber and foil or flex ducting with fiberglass and foil. There is a boiler/laundry room located on the northwest side of the ground floor, with boiler unit and hot water tanks. All of the water piping observed was insulated with foam or metal jacketed foam.

Suspect Asbestos Materials: After a visual inspection at the subject site was completed, the following suspect asbestos materials were noted. These materials were consistent throughout most or all of the areas inspected with limited variations found between rooms. Please refer to the attached bulk sample logs and laboratory analytical reports for more information.

The following suspect materials were sampled as part of our survey:

Asbestos Definitions and Terms

Asbestos containing material (ACM): Federal regulations define an ACM as any material or product that contains more than 1% asbestos.

Asbestos renovation: Defined by federal regulation (NESHAPS) as the removal of more than 160 square feet or 260 linear feet of ACM. OSHA requires registration of all contractors removing more than 100 sq. ft. on any project.

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 6

Friable ACM: any ACM that when dry can be crumbled, pulverized, or reduced to powder by normal hand pressure.

Non-friable ACM: any ACM that cannot be reduced to powder by normal hand pressure.

Category I non-friable ACM: asbestos-containing packings, gaskets, resilient floor covering, and asphalt roofing products. (typically pliable materials, including sealants and mastics)

Category II non-friable ACM: any other ACM that when dry cannot be reduced to powder by hand pressure. (typically non-pliable/cementitious materials)

Regulated Asbestos Containing Material (RACM): any friable ACM that will be removed during a renovation of a regulated structure. ACM that will become friable due to the removal technique is also regulated. Note: while linoleum flooring is considered Category II ACM while managed in place, removal always renders it friable.

Presumed Asbestos Containing Materials (PACM): This designation is for those materials which are normally asbestos containing but were not sampled due to access issues or potential for irreparable damage. This typically includes transite (asbestos cement) piping or sheeting, or HVAC insulation materials in walls, under floors, etc. where destructive testing is not recommended. Regulations allow asbestos inspectors to “presume” that these materials contain asbestos without laboratory data based on the inspector’s experience and knowledge of building materials.

Trace (<1%) Asbestos: Federal regulations define an asbestos containing material (ACM) as any compound with greater than 1% asbestos. State regulations in California further define an “asbestos containing construction material” (ACCM) as any compound which meets or exceeds a concentration of 0.1% asbestos by weight. This definition is primarily for worker and occupant protection during disturbance work. The polarized light microscopy (PLM) method does not quantify the concentration asbestos in bulk samples at levels of less than 1%. Furthermore, PLM methodology will include all fibers with a similar aspect ratio (3:1) to asbestos fibers, and therefore may count non-asbestos fibers as part of the overall total. PLM analytical methods must report a “trace” amount where fibers are noted in concentrations of less than 1% of the total.

Further analysis by more quantitative methods such as “Point Count” or transmission electron microscopy (TEM) are required to quantify the actual concentration of asbestos in “trace” PLM sample results.

Summary: Asbestos was detected in a limited number of building materials tested as part of our survey of the subject site. This included corrugated asbestos-cement (transite) roofing panels and transite panels located under the roofing on the upper walls of the warehouse. At least one sample of roofing mastic on the warehouse roof tested positive for a “trace” or <1% asbestos.

Our survey included testing of representative building materials throughout Building 2 and the detached incinerator. Based on the results of our survey, selected materials may require special handling or control measures during renovation or disturbance work. Please see the Conclusions & Recommendations (Section 4.0) below for further discussion regarding our survey findings.

3.0 Lead-Based Paint & Lead Component Survey Findings

FCG was contracted to perform field testing to determine the presence of lead-based paint or lead-based components at the subject site buildings. A visual inspection of the site was conducted to identify areas of suspect lead based paint or coatings. Screening for lead was conducted through the collection of paint chip and/or bulk material samples in accordance with current regulatory requirements. All field work was conducted by a Certified Lead Inspector/Assessor. The findings of this survey should be used by contracting personnel to determine appropriate lead safe work practices prior to renovations at the subject site.

Background Information on Lead Paint Requirements: According to the World Health Organization (WHO), lead is a toxic metal whose widespread use has caused extensive environmental contamination and health problems in many parts of the world. It is a cumulative toxicant that affects multiple body systems, including the neurologic, hematologic, gastrointestinal, cardiovascular, and renal systems. Children are particularly vulnerable to the neurotoxic effects of lead, and even relatively low levels of exposure can cause serious and in some cases irreversible neurological damage. Recent reductions in the use of lead in paints, fuels, plumbing fixtures and pipe solder have resulted in substantial reductions in blood lead levels. However, significant sources of lead exposure still remain, particularly in developing countries.

Lead-Based Paint (LBP) is defined as a paint or other coating that contains lead equal to or greater than 5,000 parts per million (ppm) or 0.5% by weight. Disturbance of lead-based paint or lead containing materials caused by building renovations or similar disturbance work has been proven to result in exposure to workers and building occupants through inhalation or ingestion of lead contaminated dust. Several Federal and State regulations apply to the disturbance and possible exposure to lead from paints and other coatings. OSHA regulations found within Title 29 of the Code of Federal Regulations (Section 1926.62) apply to worker exposure as regulated under the Lead-in-Construction Standard. HUD and EPA established regulations (Title X) for housing and guidelines for proper handling of lead paint projects. These regulations are primarily directed towards the protection of young children in older housing who are more susceptible to lead poisoning and more adversely affected by lead exposure. The EPA recently issued a Lead Renovation, Repair and Painting (RRP) Program to address lead-based paint hazards created by renovation, repair and painting activities that disturb lead-based paint in target housing and child-occupied facilities.

OSHA studies estimate that disturbance of paints containing more than 600 ppm lead may result in exposure above the recommended Action Level of 30 micrograms per cubic meter (30 ug/m3) or the Permissible Exposure Limit (PEL) of 50 ug/m3. Therefore, even disturbance of paint coatings or lead containing materials that do not meet the definition of “lead-based” may result in lead exposure to workers or occupants, or may cause contamination of the site from the generation of lead dust and debris.

Scope of Services: FCG’s scope of services involved field testing through the collection of surface samples (paint chips, bulk materials) from representative surfaces and building materials located throughout the subject site. See the Attachments to this report for more information on XRF sampling methodology.

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 8

Testing Methodology: Per US regulations, paints or coatings are considered to be “lead-based” at concentrations at or above 5,000 ppm or 0.5% by weight. FCG collected bulk paint chip samples from representative surfaces throughout the subject site in each of the areas currently occupied by the NAMRU-6 operations. The bulk samples were collected by paint chip or bulk sampling methods to remove the surface coating down to the substrate. All samples were analyzed by EPA Methods 3050B/7420 for Total Lead using atomic adsorption and an acid digestion process. Please see the attached laboratory analytical report for detailed information.

Interior wall paint in animal rooms (green color). Note: The green colored paint detected in Room 112 may exist in additional areas, primarily in the animal rooms where our access was limited. All areas of green paint in the animal rooms or nearby should be managed as LBP.

Summary of Lead Containing Paint (>600 ppm): The following materials/surfaces were identified with lead concentrations less than the definition of LBP (5,000 ppm) but greater than 600 ppm and may therefore result in lead exposure above the OSHA Action Level or Permissible Exposure Limit for workers conducting disturbance activities. Disturbance of these materials may also result in contamination of the site:

Exterior metal doors and frames (grey paint) including warehouse roll up and basement storage cage

Interior roof deck (black paint)

Interior fire sprinkler pipe (red paint)

Interior door and doorframe in the animal facility (grey paint)

Exterior stairways and roof access ladders (green paint)

4.0 Additional Hazardous Materials Assessment

PCBs in Transformers: PCBs were often used in electrical transformers as a dielectric fluid for fire retarding properties. These transformers were used up until the late-1970s when US manufacturers phased out the use of PCBs due to toxicity issues. It is not known if Peru or other South American countries implemented similar restrictions. As the property was reportedly constructed in the 1980s, there is limited potential for PCB-containing transformers to be present. We did not observe any transformers on site that appeared to be liquid-storage type that would be suspect for PCBs.

Fluorescent Light Fixtures/Light Tubes: Fluorescent light fixtures are located throughout all floors of the building. Most of the fixtures are 2’ or 4’ long with either 2 or 4 light tubes in each fixture. Older light fixtures may contain PCBs in the transformers/ballasts. Fluorescent light tubes are known to contain mercury vapor and must be properly recycled or disposed. This includes green label lamps which contain low concentrations of mercury. As the building was reportedly constructed in the 1980’s, there is limited potential for PCBs to be present in light ballasts. Previous inspection of representative light ballasts in 2010 by SELC revealed no indication of PCB-containing fixtures.

Estimated Light Fixtures/Tubes or Lamps: the following is a rough estimate of the number of fluorescent light fixtures and tubes by floor:

Basement: Est. 25 fixtures, 50-100 light tubes

1st floor: Est. 80 fixtures, 160-320 light tubes

2nd floor: Est. 48 fixtures, 96-192 light tubes

If the light fixtures will be replaced or removed as part of the planned renovation project, all ballasts should be inspected for decals or labels indicating “No PCBs” or similar language. All ballasts without any decals or labeling indicating the absence of PCBs should be presumed to

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 11 contain PCBs and properly disposed at a permitted facility. Regardless, disposal of all light ballasts or transformers will require proper handling and disposal or recycle. All fluorescent light tubes will also require proper recycling or disposal due to mercury content.

Laboratory Reagents/Other Chemicals: There are numerous laboratory analytical processes that utilize various chemical reagents, requiring the on-site storage and use of these items. A review of chemical storage and use was not a part of this scope of work. All lab chemicals and reagents used on site are under the control of laboratory personnel, with appropriate storage and handling procedures in place. Minor amounts of cleaning agents, lubricants, paints and other chemicals used in routine site maintenance. These items were noted in consumer quantities. No concerns were found.

Other Universal Wastes: Universal wastes include electronic devices (i.e., computer monitors, electronic equipment, etc.), batteries, mercury-containing thermostats or switches, aerosol cans and similar items. If any of these items will be affected by the planned renovations, they should be disposed or recycled in accordance with local regulations. Many of these items may meet the definition of hazardous waste and should be properly characterized for disposal. We found no evidence of older thermostats or switches that appeared to utilize mercury.

5.0 Conclusions & Recommendations

A hazardous materials building survey of the NAMRU-6 site has been completed per the terms of our agreement to define hazardous materials issues as part of the Facilities Utilization Study of this site. Based on our visual observations and our evaluation of analytical data, we conclude the following:

Asbestos: The following materials were identified as containing asbestos in at the subject site:

Warehouse Roofing Panels: Corrugated asbestos-cement (“Transite”) roofing panels (30% chrysotile asbestos) are located on the warehouse structure. The roof panels are considered a Category II, non-friable material in fair condition. There is an estimated quantity of approximately 2,000 sq. ft. of asbestos roofing panels.

Warehouse Upper Wall Panels: Narrow asbestos-cement panels (5% chrysotile) are located above the top edge of the wall sections on the east and west sides of the warehouse, extending up to the underside of the corrugated roof deck. These materials are considered Category II, non-friable material in fair condition. There is estimated quantity of approximately 160 sq. ft. of flat wall panels on the underside of the corrugated roof.

Warehouse Roofing Mastic: The black mastic used to seal around the fan vent penetrations of the warehouse roof showed a “trace” or <1% asbestos. The mastic is in intact but in older, poor condition. This material should be managed as asbestos containing unless more quantitative testing analysis (point count, TEM, etc.) is conducted. This is a Category I, non-friable material in poor condition. There is an estimated quantity of approximately 10 sq. ft. of mastic material.

All other suspect materials tested at the site showed no detectable asbestos. This included testing of wall surfacing/plaster materials, drywall ceiling panels, exterior

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 12 waterproofing mastics, tile mortar and grout materials, laboratory countertops and patching/joint compound materials. No suspect thermal systems insulation, resilient vinyl flooring, fireproofing or similar materials were found on site.

Asbestos Recommendations: Based on our survey of building materials at the site, asbestos containing materials were detected at the site in the form of asbestos-cement roof panels, upper wall panels and roofing mastics as noted above. These materials are intact and can be managed in place under the terms of a properly designed Operations & Maintenance (O&M) Program. If the materials are to be disturbed as part of site renovations, all work must be conducted by properly trained asbestos contractors using appropriate controls and work practices to prevent asbestos fiber emissions.

Lead-Based Paint and Lead Components: A limited number of painted surfaces or materials at the site were found to contain lead above the regulatory definition of Lead-Based Paint or LBP (0.5% by weight or 5,000 parts per million). These materials should be disturbed only by properly trained and protected workers using “Lead Safe Work Practices”, to prevent the generation of a lead hazard. The materials which meet the definition of LBP are listed below:

Identified Lead-Based Paint (LBP): The following surfaces/materials tested above the regulated level of 5,000 ppm:

Boiler room expansion tank frame in northeast boiler room (light brown color)

Boiler room expansion tank pipes in northeast boiler room (blue color)

Exterior curb paint in parking area and driveway to basement (yellow color)

Exterior fire sprinkler pipes and valves (red color)

Exterior loading dock awning frame adjacent to warehouse (brown color)

Interior wall paint in animal rooms (green color)

In addition, a limited number of painted surfaces showed concentrations of lead below the 5,000 ppm or 0.5% regulated level of LBP, but greater than 600 ppm. These materials may cause exposure to workers performing “trigger tasks” such as grinding, cutting, sanding or similar operations where lead dust may be generated. These operations may also cause contamination of the site or generation of a lead hazard which may affect occupants.

Painted Surfaces with Lead above 600 ppm (non-LBP): The following materials contain concentrations of lead which exceed 600 ppm, but are below the regulated level of LBP:

Exterior metal doors and frames, including warehouse roll up and basement storage cage (grey paint)

Interior roof deck (black paint)

Interior fire sprinkler pipe (red paint)

Lead Recommendations: All site work where lead based paint or lead containing paint (>600 ppm) may be disturbed should be conducted by trained workers using Lead Safe Work Practices. This will include appropriate containment, wet methods and use of hand tools or similar methods that will minimize the generation of airborne dust emissions and potential lead hazards.

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 13

Lead waste materials may be considered hazardous waste and should be properly contained and transported for offsite disposal at a properly permitted facility. If necessary, waste characterization testing should be conducted to ensure proper handling and disposal. Local regulations should be reviewed to determine hazardous waste disposal criteria.

PCBs & Mercury (Fluorescent Light Fixtures/Light Tubes): Fluorescent lighting fixtures are located throughout the site and may pose concerns related to PCBs and mercury. Older light fixtures are known to contain ballasts or transformers that contain PCBs as an insulating fluid to keep the transformers from overheating. If fluorescent light fixtures will be replaced or disposed, each of the ballasts must be inspected. Those ballasts with a “No PCBs” decal should be segregated from the ballasts without an identifying label or decal. Those ballasts without a “No PCBs” decal should be presumed to contain PCBs and must be properly stored in an approved container and transported to a permitted disposal facility. All fluorescent light tubes must be properly recycled or disposed due to the presence of mercury vapor inside each tube. No PCB containing transformers were noted during our inspection.

6.0 Cost Estimate for Hazardous Materials Mitigation

Without knowledge of local environmental regulations and contracting costs, it is difficult to estimate costs for abatement or mitigation of asbestos, lead paint or other items. The following costs are typical of what may be incurred in the US as part of site renovation work, and may be applied here for budgeting purposes. All costs exclude travel, lodging and other expenses that might be incurred if a US contracting firm is hired.

6.1 Asbestos Abatement: The following costs are estimated for asbestos work that might be required if all asbestos containing materials were to be removed:

2,000 sq. ft. of transite roofing panels: Est. $10/sf x 2,000 sf = $20,000 (removal using booms, high reach or similar equipment.)

160 sf of upper wall panels at Warehouse: Est. $6/sf x 160 sf = $960

10 sf roof penetration mastics at fan vents: Est. $12/sf x 10 sf = $120

Unit pricing: Est. $800/man/day

Mobilization Fees: $1,000 (excludes travel or per diem, etc. for international work) o Total Estimated Fee for Asbestos Abatement = $22,080

6.2 Lead Mitigation or Abatement:

Cost estimates for lead abatement or mitigation include painting preparation, component removal or other tasks where lead-based paint may be disturbed or encountered. In most cases, the lead paint would be managed in place by removing any loose or flaking material and encapsulating with a new coat of paint. If certain materials or components are to be removed, then lead safe work practices would be required by trained workers. Typically, there is no requirement to remove lead paint from a material or component prior to demolition or other removal activities. Given a rough estimate of $5/sq. ft. for paint preparation tasks, the following rough costs may apply:

Est. Lead Mitigation of 2,000 sq. ft. x $5/sq. ft. = $10,000 Optional fee for waste disposal of lead paint chips = $500 Unit Price = $5/sq. ft.

SS&A-5, NAMRU-6 Peru, Haz Mat Survey-rev3 14

6.3 Fluorescent Light Removal, Recycling & Disposal:

This cost estimate assumes the following parameters:

Removal of 153 light fixtures @ $40 ea. = $6,120

Disposal of 153 ballasts @ $650/drum = $650

Disposal or recycle of 612 light tubes @ $0.50 ea. = $306 o Total Cost Estimate for Fluorescent Light Recycling & Disposal = $7,076

6.4 Estimated Cost for Hazardous Materials Abatement/Mitigation = $39,656* *Note: This is a “ballpark” estimate for budgeting purposes only. Actual abatement or mitigation costs should be estimated by qualified, local hazardous materials contractors using field verification of material quantities, removal methods, disposal costs, etc. Project costs may be significantly affected by local environmental regulations, field conditions, unidentified materials found during site work or other issues which may be unknown at this time. FCG makes no warranty or guarantee as to the accuracy of the estimated quantities, volumes, unit costs or other estimated pricing. Client should obtain fixed bids from local, qualified contractors for a more accurate cost estimate.

Limitations Statement

The data compiled and evaluated as part of this assessment was limited and may not represent all conditions at the subject site. Asbestos was widely used until the late 1970’s in thousands of building materials (i.e. joint compound, wallboard, thermal system insulation (TSI), acoustical ceiling, roofing material, etc.), making it difficult to locate all areas of ACM usage. This assessment reflects the data collected from the specific locations tested to identify Asbestos Containing Materials (ACM) in those locations and may not be all encompassing. There is always potential for asbestos containing materials to be missed due to problems with accessibility, and the broad variety of uses. The presence or absence of lead-based paint or lead-based paint hazards applies only to the tested or assessed surfaces on the date of the field visit. It should be understood that conditions noted within this report were accurate at the time of the inspection and in no way reflect the conditions at the property after the date of the inspection.

All data collection, findings, conclusions and recommendations presented by FCG within this report are based upon limited data using current standard practices accepted within the industry. The conclusions and recommendations presented within this report are based on current regulations and the professional experience of the certified professionals involved in this project.

The data collected during this assessment and any resulting recommendations shall be used only by the client for the site described in this report. Any use or reliance of this report by a third party, including any of its information or recommendations, without the explicit authorization of the client shall be strictly at the risk of the third party.

It should not be misconstrued that this assessment has identified any or all environmental conditions at the subject site. FCG makes no representations regarding the accuracy of the enclosed data and will not be held responsible for any incidental or consequential loss or punitive damages including but not limited to, loss of profits or revenues, loss of use of a facility or land, delay in construction or action of regulatory agencies.
