1.0 INTRODUCTION

CDW Consultants, Inc. (CDW) is pleased to present this report summarizing the findings of the preliminary suspect asbestos-containing materials (ACM), lead-based paint (LBP), polychlorinated biphenyls (PCBs), and hazardous materials survey of portions of Buildings 990, 1319 and 1351 at the Naval Undersea Warfare Center Division Newport (NUWCDIVNPT) located at Naval Base

Newport, Rhode Island (“Site”). In November and December 2020, Ms. Susan Cahalan (Rhode

Island Asbestos Inspector #AAC-1023) conducted an inspection for suspect materials. An inspection is required by the United States Environmental Protection Agency (USEPA) National Emission

Standards for Hazardous Air Pollutants (NESHAP), prior to scheduled building/structure renovations. Additionally, the Rhode Island Department of Health (RIDOH) and Rhode Island

Department of Environmental Management (RIDEM) regulate ACM associated with renovation, demolition, and asbestos abatement projects. Samples of suspect materials were collected to confirm the presence or absence of ACM, LBP and PCBs. Suspect materials were grouped into homogenous areas. A homogenous area is an area that is similar in color, texture and date of application. Hand tools were used to collect bulk samples which were promptly placed in sealed plastic bags using a unique numbering system. Samples were not collected of non-suspect materials, including wood, fiberglass, plastic, ceramic, concrete, neoprene/rubber, glass, and carpeting.

2.0 PROJECT UNDERSTANDING

The scope of work was to provide a preliminary hazardous materials survey and sampling as required to verify of the presence of hazardous materials such as ACM, LBP, PCBs and other hazardous materials (mercury, oil etc.) that may be impacted by the scope of the work at portions of

Buildings 990, 1319 and 1351. The objective of this work was to evaluate the HVAC systems at each of the three buildings at NUWCDIVNPT and to provide a design for HVAC system repairs, improvements and upgrades. The overall scope of work is to evaluate options for HVAC upgrades in each of the buildings, including roof penetrations and a wall penetration on Building 990. Note that roof access was not allowed at Building 1319 due to equipment emitting radiation. Also, due to security concerns, the laboratories were not assessed.

3.0 GENERAL SITE CONDITIONS

Building 990

Building 990 is 57,000 square foot and was constructed in 1975. It is a 6-story building that contains office space. The building is constructed of structural steel frame supported on concrete spread footings. The floor construction is composite metal deck with concrete fill and the roof construction is metal decking. The roof system is a flat EPDM membrane with rigid insulation overlaying an existing tar and gravel built up roof on rigid insulation. The roof EPDM system was recently repaired/replaced in 2014. The exterior building envelope consists of an exterior brick veneer with reinforced concrete masonry (CMU) back up wall system. The exterior walls have continuous strip windows and punched windows.

The building is served by a roof mounted direct expansion air handling unit which only provides cooling and ventilation air during the summer season and a central station air handling unit in a first-floor mechanical room that provides cooling and heating air during the remaining time of the year.

The distribution at each floor is provided through galvanized sheet metal ductwork to variable volume supply diffusers.

The building is supplied with medium pressure steam from a base wide steam system. The building has a steam to hot water heat exchangers which provides heating hot water. The heating hot water is pumped throughout the building in steel insulated piping. The hot water serves various terminal pieces of equipment including fin tube, unit heaters and provides heating hot water to the air handling unit that provides conditioned air to the office spaces. The cooling system includes water chillers and condensers which provides chilled water which is pumped throughout the building in steel insulated piping. Observed pipe insulation within the mechanical room and above drop ceilings on other floors primarily consist of fiberglass with some suspect ACM fittings. Additionally, mold was observed in the main mechanical room on pipes and equipment.

Building 1319

Building 1319 is 103,000 square feet and was constructed in 1996. It is a 3-story building that includes laboratory and office space. The building is constructed of structural steel frame supported on concrete spread footings. The floor construction is composite metal deck with concrete fill and the roof construction is structural light gage metal decking. The roof system is a flat EPDM roof membrane over tapered rigid insulation. The exterior building envelope consists of an exterior brick veneer with cold-formed light gage metal stud back up wall system. The exterior walls have continuous strip windows, punched windows, and a curtain wall system on the east building elevation. A large mechanical room with various forms of mechanical equipment including switchboards, generators, pumps, hot water boilers, HVAC, and various tanks. There is also a fire suppression system with piping that runs throughout the building. In addition, there is a 295-gallon

AST filled with diesel fuel in the mechanical room. There are also several butane tanks stored throughout the room. The heating, ventilation, and air conditioning is central and contains fiberglass ducting. Pipe runs and elbows were insulated with fiberglass insulation.

The building is supplied with medium pressure steam from a base wide steam system which is directed to a steam to hot water heat exchangers which provides heating hot water. The heating hot water is pumped throughout the building in steel insulated piping. The hot water serves various terminal pieces of equipment including fin tube, unit heaters, lab fan coils and also provides heating hot water to the air handling unit that provides air conditioning to the office spaces. The cooling system includes indoor water chillers and closed-circuit cooling towers which produces chilled water which is pumped throughout the building in steel insulated piping.

The building is served by a central station air handling unit located in the basement which provides heating and cooling air to each floor office area through galvanized sheet metal ductwork to variable volume terminal units. The lab spaces are served by two pipe fan coil units for cooling with a dedicated central station air handler for ventilation located in the basement. CDW visually inspected the VFDs above the drop ceiling panels and did not observe any suspect ACM. Observed pipe and

HVAC insulation within the mechanical room and above drop ceilings on other floors consist of fiberglass. Additionally, mold was observed in the main mechanical room on pipes and equipment.

Building 1351

Building 1351 is a 60,000 square foot building constructed in 2000. It is a 4-story building that includes office space. The building is constructed of structural steel frame supported on concrete spread footings. The floor construction is composite metal deck with concrete fill and the roof construction is structural light gage metal decking. The roof system is a flat EPDM roof membrane over tapered rigid insulation. The exterior building envelope consists of an exterior brick veneer with curtain wall light gage metal stud back up wall system. The exterior walls have continuous aluminum strip windows with tinted double wall glazing.

The building contains one large mechanical room with various forms of mechanical equipment including: air conditioning units, chilling units for water, generators, pumps, hot water boilers, HVAC, and air handling units. There is a concrete pit with piping that drops down approximately 12 feet that is confined space entry. The heating, ventilation, and air conditioning is central and contains fiberglass ducting. Pipe runs, elbows and fittings are insulated with fiberglass.

The building is supplied with medium pressure steam from a base wide steam system which is directed to a steam to hot water heat exchangers which produces heating hot water. The heating hot water is pumped throughout the building in steel insulated piping. The hot water serves various terminal pieces of equipment including fin tube, unit heaters and provides heating hot water to the various air handling units that provide conditioned air to the office spaces. The cooling system includes an air-cooled liquid chiller which produces chilled water that is pumped throughout the building in steel insulated piping. The chilled water serves the air handlers that are located at each floor. The roof mounted chiller was replaced in 2015. Each floor of the building is served by a central station air handling unit which provides heating and cooling air to office area through galvanized sheet metal ductwork to variable volume supply diffusers.

5.0 ASBESTOS SURVEY

5.1 Methods

The investigative work for the asbestos survey included conducting a visual inspection of accessible areas of the area of mechanical rooms and behind brick façade of building 990 near louver next to mechanical room. The roofing materials were also sampled with the assistance of a contractor to core and repair roofing. Once the visual inspection was completed, the building components were categorized into homogeneous areas. CDW collected bulk samples of different homogeneous suspect materials for asbestos analysis. The bulk samples were delivered under chain of custody to Asbestos

Identification Laboratory, Inc. (AIL) located in Woburn, Massachusetts. AIL is a state licensed

(#AAL-121) and NVLAP-accredited laboratory (lab code #200919-0) for asbestos analysis. Bulk samples were analyzed for asbestos content by polarized light microscopy (PLM) using EPA Method

600/R-93/116. A positive stop method was used – if one sample in a homogeneous group is positive then additional samples of the same material are not analyzed. Samples analyzed to contain greater than 1% asbestos are to be treated as ACM as defined by the USEPA and Rhode Island Department of Environmental Management (RIDEM). The laboratory analytical reports are included in

Appendix A.

5.3 Recommendations

Prior to disturbance, the ACM identified must be abated by a Rhode Island licensed asbestos abatement contractor following all federal, state & local regulations governing asbestos abatement.

A copy of the asbestos waste shipment record must be received within 30 days of removal from the

Site. Asbestos air quality sampling must be conducted under USEPA and RIDOH regulations following asbestos abatement and prior to re-occupancy of the spaces. If additional materials are discovered that have not been sampled, those materials should be considered ACMs until laboratory analysis determines otherwise. Additionally, all abatement programs must follow the requirements outlined in the Unified Facilities Guide Specifications.

The Environmental Protection Agency (EPA) and US Department of Housing and Urban

Development definitions defines LBP as any paint or surface coating that contains lead equal to exceeding one milligram per square centimeter (1.0 mg/cm2) or 0.5% by weight. U.S. Navy defines any percentage of lead above laboratory limits of detection detected as “lead-containing paint.”

Lead containing paint consists of:

• White paint on HVAC metal in Mechanical Room in Building 990

• Lintel paint building 990 exterior

• Lintel paint building 1319 exterior

Lead based paint consists of:

• Black/Red paint on duct frame in mechanical room Building 990

6.3 Recommendations

Based on the conclusions of this testing, the following recommendations are offered:

• In accordance with the EPA Lead Renovation, Repair, and Painting (RRP) Rule 40 CFR 745, workers, visitors, and the public must be protected from lead dust generated during the demolition of LBP or LCP coated surfaces.

• During demolition or renovation, paint materials containing lead should not be sanded, scraped, drilled, or otherwise altered unless proper engineering controls are used to prevent migration of fugitive lead containing dust from the work area. Under OSHA regulations, any demolition or renovation to be performed at a structure where lead in paint and dust is present must be performed in accordance with a worker protection policy, including, but not limited to, appropriate training, medical monitoring, respiratory protection, and other protective equipment. Comply with guidelines outlined in specifications UFGS-028313 and UFGS-

028319.

• In addition to the worker protection requirements stipulated by OSHA and Military, RIDOH and the USEPA regulate the disposal of wastes that are potentially hazardous. Such wastes may include paint chips and residue generated during abatement or repainting work, or whole components, that are coated with LBP and that are disposed of as the result of renovation or demolition work. To determine the required method for disposing of permeable items coated with LBP, the RIDOH and the USEPA require representative sampling of the debris to determine the quantity of lead that would be expected to leach into the environment if the debris were disposed of in a landfill. The representative sample(s) must be analyzed by the Toxicity

Characteristic Leaching Process (TCLP) to determine the proper disposal method.

• Those components/colors not tested, or in locations not inventoried in this report, should be tested for lead content prior to disturbance that may cause airborne release of lead.

7.0 POLYCHLORATED BIPHENYLS

9.3 Recommendations

Prior to removal, light tubes, ballasts, lead and tritium batteries, thermostats and switches will require proper handling, removal, transportation and off-site recycling/reclamation. Acetylene cylinders and refrigerants must be transported and disposed in accordance with state, federal and military regulations. Additionally, all items identified in the above table shall be collected and properly disposed of prior to renovation activities at the Site and comply with guidelines outlined in the USGS specifications.

Due to visible mold associated with piping and other mechanical components in Buildings 990, 1319 and 1351, a limited mold survey is also recommended.

Limitations

The conclusions are limited to the information available at the time of the field survey and the scope of services, as defined. No subsurface soil or groundwater sampling and analysis was performed.

Where access to portions of the Site or to structures on the site was unavailable or limited, CDW renders no opinion as to the presence of hazardous material or the presence of indirect evidence related to hazardous material in that portion of the site or structure. This report cannot be solely relied upon for renovation or demolition. The sampling performed forms the basis for conclusions expressed and areas inaccessible for testing limits those conclusions. No other conclusions, interpretations or recommendations are contained or implied in this report other than those expressed. While CDW followed industry standards during the inspection, we do not warrant that all suspect hazardous building materials were identified in or on the buildings and shall not be held liable related to future abatement costs related to hazardous materials that are either not discovered or not appropriately characterized. This is due in part to inherent problems with every building inspection, such as, but not limited to:

• Seemingly homogeneous materials that are not in fact homogeneous;

• Seemingly representative locations that are not in fact representative;

• Layered materials that are not uniformly present or are isolated;

• Materials that are present and accessible but were not considered to be hazardous,

• Materials that are present in an isolated and limited quantity; and

• Material that is present in locations that are unsafe or otherwise difficult to access.

Client acknowledges that CDW's inspection is limited, and all hazardous materials may only become apparent during future renovation or demolition. During future renovation/demolition work, it is likely that additional hazardous materials or materials suspected of being hazardous will be identified. Such materials should be assumed to be hazardous unless appropriate evaluation or sampling and analysis demonstrate otherwise. No other use of this report is warranted without the written consent of CDW Consultants, Inc.

Asbestos Identification Laboratory

Dear Susan Cahalan, Thank you Susan Cahalan for your business.

Michael Manning Owner/Director

Asbestos Identification Laboratory has completed the analysis of the samples from your office for the above referenced project.

The information and analysis contained in this report have been generated using the EPA /600/R-93/116 Method for the Determination of Asbestos in Bulk Building Materials. Materials or products that contain more than 1% of any kind or combination of asbestos are considered an asbestos containing building material as determined by the EPA. This Polarized Light Microscope (PLM) technique may be performed either by visual estimation or point counting. Point counting provides a determination of the area percentage of asbestos in a sample. If the asbestos is estimated to be less than 10% by visual estimation of friable material, the determination may be repeated using the point counting technique. The results of the point counting supersede visual PLM results. Results in this report only relate to the items tested. This report may not be used by the customer to claim product endorsement by NVLAP or any other U.S. Government Agency.

Comments:

Results are reported on an ``as received`` basis, and are not corrected for dry weight.

PCB Comment:

For PCBs, in order to reach the desired RL, multiple cleanup steps were performed. The extract was cleaned up with a combination of sulfuric acid, potassium permanganate, copper powder and additional florisil.

All soils, solids and sludges are reported on a dry weight basis unless otherwise noted in the sample comments.
