Re: Buildings 27, 28, 31, and 16 Connecticut Air National Guard, 100 Nicholson Road, East Granby, CT Building Survey Findings RPF File No. 199476

Dear Mr. Gorham:

On October 17, 2019 and October 18, 2019, RPF Environmental, Inc. (RPF) conducted a survey at the Connecticut Air National Guard located at 100 Nicholson Road in East Granby, CT. The survey was performed in the interior portions of the building, as designated by you or your site representative, for accessible hazardous building material as indicated herein. Below is a summary of findings, discussion of the results and preliminary recommendations for proper management of the identified hazardous building material. Attached to this report are the survey data tables, laboratory results, survey methodologies and limitations.

This report is not intended to be used as an abatement specification or work plan. To proceed with abatement work, the following important steps are necessary:

1. A work plan or project design documents must be prepared prior to abatement by a certified abatement project designer. As part of the design, additional site testing and analysis may be required as discussed in this report.

2. The abatement specification or work plan should then be used to solicit bids from qualified abatement contractors. Only properly licensed contractors should be used for asbestos abatement and disposal.

3. A qualified industrial hygiene/testing consultant should conduct sufficient testing and inspections of the work, independent of the abatement contractor. The consultant should also prepare final abatement reports for the work.

Summary of Findings

The scope of this survey included interior areas within buildings 27, 28, 16, and 31. Buildings 16 and 27 are 1-story, masonry structures that house various offices, common areas and garages.

Building 28 is a 1-story, masonry and metal storage area that is used as an open garage. Building 31 is a 1-story, masonry building that is made up of five (5) garage bays. Accessible exterior portions of each building were inventoried only, sampling these materials and surveying the roofs of these buildings were outside the scope of this survey.

The scope of the survey included accessible asbestos-containing building material in accordance with the initial asbestos inspection requirements prior to renovation or demolition work as stated in the State regulations and applicable federal regulations. In addition, the survey included screening for lead paint (LP), polychlorinated biphenyls (PCB) light ballasts, mercury switches, refrigerants, suspect PCB caulking, universal wastes, building system hydraulics, and fluorescent light bulbs.

Asbestos

Several types of suspect asbestos-containing building material (ACBM) were observed by RPF, including friable and nonfriable suspect material. No asbestos was detected in the accessible materials sampled in buildings 27, 28, and 31. Based on the testing performed by RPF, asbestos was detected in the following materials collected in building 16:

Tan Black Floor Tile Mastic

Exterior portions of the buildings were inventoried only. Sampling was not performed of exterior suspect ACBM in order not to damage the integrity of the materials at this time.

As such, the door caulking, window caulking, and built-up roofing material is assumed to be ACBM for the purposes of this inspection. When feasible and prior to demolition or disturbance, the door caulking, window caulking, and built-up roofing should be tested including representative core samples and analysis of the different suspect materials.

Lead Paint

Based on the year of construction and extent of renovation conducted over the years, it is reasonable to assume that some lead paint (LP) is present. RPF conducted limited spot testing of paint and LP was confirmed to be present on various interior building components in Buildings 27, 28, and 16. The intent of the lead testing was for potential lead hazardous waste disposal screening purposes only.

Building Survey Findings Page 3

Polychlorinated Biphenyls, Mercury, Refrigerants, Building System Hydraulics, Universal Wastes

Based on the RPF visual observations, polychlorinated biphenyl (PCB) containing light ballasts, universal wastes, and fluorescent light bulbs are present throughout Buildings 27, 16, and 31. Mercury switches and building system hydraulics were not observed in any of the buildings surveyed. In addition, RPF observed refrigerators in Buildings 27 and 16 which are assumed to contain Freon or other CFCs.

PCB in Caulking

Based on the RPF visual observations, six (6) composite samples were collected of suspect PCB caulking present in Buildings 27, 16, and 31. Two samples were collected from Building 27, three samples were collected from Building 16, and one sample was collected from Building 31. PCBs were not detected in the composite samples collected during this site visit.

Depending on the extent of renovation and final construction plans, proper abatement and/or management of the materials will be required in accordance with applicable State and federal regulations. Renovation and demolition plans should be reviewed by a certified industrial hygienist and a licensed project designer for possible asbestos impact issues. Based on the impact assessment and planned usage, technical specifications should be prepared for abatement, as applicable. A management plan should also be prepared to address any asbestos or other hazardous material scheduled to remain after construction.

Discussion of Findings

Asbestos-Containing Building Material

Asbestos is the name for a group of naturally occurring minerals that separate into strong, very fine fibers. The adverse health effects associated with asbestos exposure have been extensively studied for many years. Results of these studies and epidemiological investigations have demonstrated that inhalation of asbestos fibers may lead to increased risk of developing one or more diseases. In all cases, extreme care must be used not to disturb asbestos-containing materials or to create fiber release episodes.

In the accessible locations surveyed, RPF identified eighty (80) homogeneous groups of accessible suspect asbestos-containing building material. Suspect materials were identified based on current industry standards, EPA, and other guideline listings of potential suspect ACBM.

The following is a summary list of the suspect ACBM identified and sampled during this survey:

A total of one hundred and sixty-seven (167) samples were extracted from the different groups of suspect material in accordance with EPA sampling protocols. Of the samples collected by RPF, asbestos was detected in three (3) groups of suspect ACBM.

Based on the survey findings, accessible ACBM was not identified in Buildings 27, 28, and 31.

Care should be used during demolition to inspect for possible concealed suspect material that was not accessible at the time of this inspection.

Table 1 below includes a list of interior ACBM identified in building 16, EPA category listings, and asbestos content. A listing of the different homogenous groups of suspect material identified, samples collected, and analytical results is included in Appendix A.

TABLE 1

SUMMARY OF INTERIOR ACBM IDENTIFIED

Building Material Location Approximate

Quantity EPA Category Asbestos

Results with Black Mastic Building 16, Throughout Office area section of the building

1,300 square feet Category I Nonfriable

3-6% Chrysotile

Black Mastic Building 16, Break room, 35 square feet Category I Nonfriable

6% Chrysotile

Notes: All quantities are approximate only and should be confirmed during abatement project design and abatement bidding.

The ACBM identified during this survey consists of nonfriable material. The nonfriable ACBM was observed to be in good to fair condition and, left undisturbed and properly managed, is unlikely to cause any major fiber release episodes.

Although the standard polarized light method of analysis was completed pursuant to current state and federal regulations, it is recommended that some of the collected in buildings 16 and 27 that were found to be non-detect for asbestos, as detailed on the attached results, be confirmed using gravimetric preparation methods for nonfriable ACBM for more definitive results. If you would like to arrange for this additional lab work, please contact our office as soon as possible.

It should be noted that exploration of the masonry wall cavities for the presence of suspect vermiculite in each of the buildings was not part of the scope of work. The buildings were occupied at the time of the survey and it was not feasible to explore the walls without causing damage to the structure. The walls cavities in each of the buildings should be investigated prior to any demolition or renovation activities.

Building Survey Findings Page 6

The exterior building materials of Buildings 16, 27, 28, and 31 were inventoried only at this time and sampling was outside the scope of work for this survey. As such, the exterior building materials are assumed to be ACBM for the purposes of this inspection. When feasible and prior to demolition or disturbance, the exterior building materials should be tested including representative core samples of the roofing and analysis of the different suspect materials. The following is a list of accessible suspect exterior building materials RPF observed and inventoried at each of the buildings.

The structures were in current use at the time of the survey and full destructive or exploratory survey methods were not feasible. Suspect materials encountered at the site subsequent to this survey, which are not included on the enclosed listings of suspect material sampled, should be assumed to be ACBM until proper testing proves otherwise (for example prior to any disturbance due to maintenance, renovation or demolition activity). Please notify RPF in this event to arrange for proper testing and assessments. Please reference the attached methodology and limitations.

Building Survey Findings Page 7

Lead Paint Screening

Based on the type and age of buildings construction, it is reasonable to assume that various painted surfaces contain some lead. It is not uncommon in buildings such as these and that have had various renovation and upgrades to have both lead containing paint and non-lead containing paint.

Lead is a toxic metal that was used for many years in paint and other products found in and around buildings and homes. Exposure to lead may cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Children six years old and under are most at risk; however, adults are also susceptible to the effects of lead over exposure.

For the purposes of this survey, RPF extracted a total of twenty-three (23) representative suspect paint samples from building components in these buildings. Six (6) samples were collected from Building 27, and lead was detected in 3 of the samples: in the mechanical room (black), room 9 (beige), and room G1 (beige and white). Five (5) samples were collected from Building 28, and lead was detected in one of the samples: white textured paint. Eight (8) samples were collected from Building 16, and lead was detected in 3 of the samples: rooms 003 and 009 (white) and room 016 (brown). Four (4) samples were collected from Building 31, and there was no lead detected.

The results for the paint chip testing completed during this survey are included in Tables 6 through 9 of Appendix A. Based on this limited testing, it should be assumed that other painted surfaces at the site may also contain lead.

Current State of Connecticut Lead Poisoning regulations consider any paint that contains greater than 0.5 percent by weight to be lead-based paint. However, the intent of this survey was for construction purposes only and preliminary demolition waste stream implications, not for compliance with CT Lead Poisoning regulations, HUD, or any regulatory abatement order.

Any surfaces with lead present should be managed in accordance with current rules and guidelines, including but not limited to OSHA worker safety rules and State and EPA waste handling and disposal regulations. U.S. Occupational Safety and Health Administration (OSHA) construction rules do not specify any "safe" or acceptable levels of lead within paint for the purposes of occupational exposures. Therefore, construction work involving paint found to contain lead must be completed in accordance with OSHA regulations, not limited to the lead standard, 29 CFR

1926.62. Contractors completing work in areas found to contain lead, or where it is reasonable to assume lead may be present, should be notified of the presence (and potential presence) of lead and proper work protocols should be used.

As lead was found to be present in the screening, proper waste testing with TCLP extraction for lead and potentially other toxic materials should also be completed prior to disposal of any waste generated in accordance with current EPA requirements. Often times it is recommended that pre-demolition TCLP testing be completed such that waste can be segregated as required during demolition activity. Construction/demolition waste that is found to contain lead greater or equal to 5.0 milligrams per liter (mg/L) by TCLP analysis must be handled and treated as hazardous waste.

Building Survey Findings Page 8

Please also note that construction and renovation work involving lead paint in housing and child-occupied facilities built before 1978 is also regulated under the EPA Renovation, Repair, and Painting (RRP) rule. Any contractors conducting such work must be properly certified and must use lead safe work methods pursuant to the EPA RRP rule. In addition, pursuant to Title X requirements landlords and sellers are required to disclose the results of lead inspections to tenants and purchasers, and to provide the warning notice and pamphlets in accordance with Title X and State requirements.

PCB Light Ballasts and Fluorescent Lamp Inventory

For this survey, RPF inventoried the fluorescent lamps throughout Buildings 27 and 16.

Fluorescent lamps were not observed in Buildings 28 and 31. Visual spot checks of fixture ballasts could not be conducted during this preliminary survey due to the systems being energized. RPF observed approximately 68 fluorescent lamp fixtures in Building 27 and approximately 55 fixtures in Building 16.

During demolition of the lights, inspections should be performed label and have any unmarked ballasts or ballasts without date stamp be assumed to be PCB containing. PCB and non-PCB ballasts should be segregated and packaged for waste disposal in accordance with State and federal requirements. There is a substantial cost difference for disposal of PCB ballasts versus non-PCB ballasts. It is also recommended that prior to proceeding with site work, it be requested that the Client or Building Owner provide documentation of PCB ballasts removed and replaced in the building, if available.

PCBs have been shown to cause chronic toxic effects and are a human carcinogen. PCBs are toxic according to the U.S. EPA and are a regulated material. The two primary federal laws that affect the handling of PCBs are the Toxic Substance Control Act and the Superfund Law (CERCLA).

Other regulations include various State requirements, Department of Transportation, U.S. OSHA, and the Resource Conservation and Recovery Act. The regulations establish various requirements for the removal, handling, storage and disposal of PCBs.

With regard to light ballasts, approximately half were manufactured prior to 1979 and nearly all pre-1979 ballasts contain PCBs. Ballasts manufactured after July 1, 1978 and that do not contain PCBs are required Please note that is possible that post 1979 ballasts may contain some PCBs in the capacitor oils and more information should be requested if needed for applicable State and federal agencies. PCBs may also be present in common household appliances with small capacitors and as dielectric fluids; other electric equipment such as transformers, switches and voltage regulators; and recent studies have shown PCB content in caulk and some paints. Documentation of current conditions and in-depth hazard assessments, and laboratory testing for these other PCB usages, is beyond the scope-of-work for this initial survey.

PCB in Caulking

A total of six (6) composite samples of building caulking were collected and submitted for analysis to determine PCB content. These samples were comprised of discrete caulking materials collected

Building Survey Findings Page 9 from various interior window trim, door trim, building seams, expansion joints in Buildings 27, 16, and 31. No suspect PCB caulking was observed in Building 28.

The samples were analyzed by Eastern Analytical, Inc. using EPA Method 8082. No detectable concentrations of PCBs were present in the interior caulking samples collected. PCB-containing caulk is considered PCB bulk product waste if the concentration of PCBs in the caulk is greater than or equal to (>) 50 ppm pursuant to 40 CFR § 761.3. PCB bulk product waste includes waste derived from manufactured products containing PCBs in a non-liquid state where the concentration at the time of designation for disposal is >50 ppm PCBs. The results of the PCB analysis are included in Appendix A. It should be noted that sampling of exterior caulking was outside the scope of work for this survey. Prior to any renovation or demolition activities in buildings 27, 28, 16, and 31, the exterior caulking should be sampled and analyzed for PCBs.

Visual Observations for Mercury Switches, Refrigerants, Building System Hydraulics, and Fluorescent Light Bulbs

Based on the spot checks by RPF, no mercury switches or thermostats were observed in Buildings 16, 27, 28, and 31. It is possible that additional switches, thermostats or heat detection devices may be encountered during renovation or demolition work and care should be used to properly handle such materials. In addition, fluorescent and high intensity discharge lamps contain a small quantity of mercury that may pose a hazard to human health or the environment if the materials are not managed properly. The lamps may also contain lead solder material. The following table depicts the approximate quantities of bulbs observed in each building.

Location Fluorescent Bulbs High Intensity Bulbs Building 27 132 9 Building 28 0 0 Building 16 158 0 Building 31 0 10

Based on the visual observations performed, RPF did not identify any building system hydraulics in the buildings surveyed. RPF observed one refrigerator in Building 27 and one refrigerator in Building 16. It is possible that additional refrigeration, cooling units, and related equipment could be present in these buildings that may contain Freon or other CFCs. These units should be handled and disposed of properly by trained personnel.

Visual Observations of Universal Wastes

Based on the spot checks performed by RPF, containers of various chemicals were observed in Buildings 16, 27, and 31. Buildings 31 and 27 had a few garage bays devoted to storing drums and large containers of various chemicals and spill kits. Building 27 also has a portion of garage bay 1 that has a hazardous chemical closet with a safety data sheet (SDS) binder present. It should also be noted that containers of cleaning products and automotive supplies were present in Buildings 27 and 16. These two buildings are service garages that not only stores vehicles but also

Building Survey Findings Page 10 perform routine maintenance and repairs on them. It is assumed that all these items would be removed from the buildings prior to demolition.

Conclusions

Based on the survey findings, the building was found to contain ACBM, LP and other hazardous building material.

In accordance with current regulatory requirements, ACBM that may be impacted or disturbed (such that asbestos fiber release occurs) by renovation, demolition or other such activity must be removed by qualified, licensed firms. Although regulations for removal of nonfriable ACBM are somewhat less stringent than the requirements for friable ACBM, it should be noted that nonfriable ACBM that is subjected to grinding, abrasion, and other forces, could be rendered friable. In this event, the nonfriable ACBM would be re-categorized friable ACBM.

ACBM that will not be impacted by renovation or demolition activity may be left in place if managed properly and if the materials are maintained in good condition. ACBM to remain in the building should be included in an asbestos management plan and operations and maintenance (O&M) program detailing the measures to be used to safely occupy the building until the ACBM is fully removed. An accredited Management Planner should prepare the O&M Program in accordance with the guidelines set forth in 40 CFR Part 763 (AHERA).

Work impacting LP, fluorescent light bulbs, mercury (and potential PCB ballasts) must be performed in accordance with current State and federal standards, including but not limited safe work practices, engineering controls, proper waste packaging, and proper disposal. Work involving LP may require notification of tenants, if rented or leased space, prior to start of work.

Sufficiently in advance of the start of renovation and/or remediation work, abatement project design should be completed. As part the initial design steps any planned renovation and demolition activity should be reviewed for potential impact on ACBM. Asbestos removal is highly regulated at the State and federal level, and in some cases, at the local level also. Notification to CT Department of Public Health is required 10-days prior to the start of interior abatement work and demolition. Only qualified, trained, and licensed firms, as applicable, should be engaged to complete asbestos removal or other abatement activity. Asbestos abatement work must be designed (abatement specifications or work plan prepared) by accredited personnel.

All employees and contractors that may access or otherwise disturb areas with suspect ACBM present should be notified of the presence of ACBM and possible hidden ACBM, and the need to use caution when proceeding with work. Appropriate notifications, labeling and other hazard communications should be completed to all employees, contractors and others in accordance with US OSHA regulations and other applicable requirements (including asbestos labeling in accordance with 29 CFR Part 1926). The scope of RPF services for this survey did not include labeling of ACBM or hazard communications to other employees, building occupants, contractors, or subcontractors.

Building Survey Findings Page 11

Documentation of current ACBM conditions and in-depth hazard assessment is beyond the scope-of-work for this initial survey. With the exception of the specific testing and analysis detailed herein, no other samples of materials, oil, water, ground water, air, or other suspect hazardous materials were collected in the course of this inspection that supports or denies these conclusions.

No additional services beyond those explicitly stated herein were performed and none should be inferred or implied. The summary and conclusions are based on reasonably ascertainable information as described in this report. RPF Environmental, Inc. makes no guarantees, warranties, or references regarding this property or the condition of the property after the period of this report.

Summary of Methodology: Asbestos-Containing Building Materials Survey

EPA accredited inspector(s) surveyed accessible space in the building or site areas included within the RPF Scope of Work (SOW) to identify suspect asbestos-containing building material (ACBM). Suspect ACBM was inventoried and categorized into homogeneous groups of materials. To the extent indicated in the report, samples were then extracted from the different groups of homogeneous materials in accordance with applicable State and federal rules and regulations.
