Re: Hazardous Material Survey Report Horticultural Research Lab 2001 South Rock Road Fort Pierce, Florida 34945 Terracon Project No. 34267020

Dear Ms. Palmer:

The purpose of this report is to present the results of the hazardous material survey performed on February 17, 2026, of the structures located at 2001 South Rock Road in Fort Pierce, Florida. This survey was conducted in general accordance with Terracon proposal number P34267020, dated January 26, 2026. We understand that these services were requested due to the planned demolition of the Clean Greenhouse, Regular Greenhouse and the planned renovation of the HVAC duct replacement within the Pilot Plant and Micro Lab buildings.

At the client’s direction, no additional interior or exterior building materials were sampled in the Pilot Plant or Micro Lab buildings beyond the grey mastic on the HVAC metal ducts observed at the time of Survey. Consequently, other building materials within these structures are assumed to contain asbestos until proven otherwise through appropriate sampling and laboratory analysis.

At the client’s request, the Clean Greenhouse and Regular Greenhouse were surveyed throughout the interior, exterior, and roof of the facility.

Asbestos was not detected in samples collected from the structures.

Lead was not detected above the detection Limit in the paint chip samples collected from the structures.

Polychlorinated biphenyls (PCBs) were not detected above the method detection limit in the samples collected from the structures.

Items with proper disposal or recycling considerations, such as ballasts and fluorescent light tubes, were observed. Please refer to the attached report for details

Terracon appreciates the opportunity to provide these services to The Johnson McAdams Firm, P.A. If you have any questions regarding this report, please contact the undersigned at (954) 703-1865.

1.0 Introduction

Terracon Consultants, Inc. (Terracon) conducted a hazardous material survey of the structures at 2001 South Rock Road in Fort Pierce, Florida 34945. The survey was conducted on February 17, 2026, by an AHERA-accredited Asbestos Building Inspectors in general accordance with Terracon proposal number. P34267020, dated January 26, 2026.

Building components were visually assessed, and homogeneous areas of suspect asbestos-containing materials (ACM) were identified and documented. Paint chip samples were collected to determine the presence or absence of lead-containing paint. Caulk samples were collected and analyzed for the presence of Polychlorinated Biphenyls (PCBs) and the buildings were visually evaluated for the presence of potential universal and hazardous waste that would likely be disturbed or impacted during the planned demolition. Asbestos sampling was performed in general accordance with EPA Asbestos Hazard Emergency Response Act (AHERA) sampling protocols, National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations, and sampling methods outlined in the Occupational Safety and Health Administration (OSHA) standards 29 Code of Federal Regulations (CFR) 1910 and 29 CFR 1926. Suspect ACM samples were delivered to an accredited laboratory for analysis by Polarized Light Microscopy (PLM). Lead samples were analyzed by Flame Atomic Absorption Spectrometry Method SW846-3050B/7000B and PCBs were analyzed by EPA Method 3540C and 8082A.

1.1 Project Objective

Based on information provided by the client, we understand the purpose of this evaluation was to identify the presence and location of accessible friable and nonfriable ACM, lead-containing paints, PCBs in caulk, and potential universal or hazardous waste that would likely be disturbed/impacted during the planned upcoming demolition/renovation of the structures.

EPA regulation 40 CFR 61, Subpart M, National Emission Standards for Hazardous Air Pollutants (NESHAP), prohibits the release of asbestos fibers to the atmosphere during demolition activities. The asbestos NESHAP requires that potentially regulated asbestos-containing building materials be identified, classified, and quantified prior to planned disturbances or demolition activities.

The project objective also included a survey and testing of surface coatings for the presence of lead that may impact worker exposure to these materials (OSHA) as well as the potential for waste materials to become hazardous waste or regulated material with regulated disposal requirements. PCB and Universal Waste were also evaluated for proper disposal.

3.0 Field Activities

The survey was conducted by Mr. Ryan Nanan (AHERA-accredited Asbestos Building Inspector Number 200206) and Mr. Jesse Beckles (AHERA-accredited Asbestos Building Inspector Number 0091-004-45969). Copies of the asbestos inspector’s certificates are attached in Appendix E. The survey was conducted in general accordance with the sample collection protocols established in EPA regulation 40 CFR 763 (AHERA). A summary of survey activities is provided below.

3.1 Asbestos

3.1.1 Visual Assessment

Our survey activities began with visual observation of the interior, exterior, and roof finishes of the structures likely to be impacted by planned demolition/renovation. A homogeneous area (HA) consists of building materials that appear similar throughout in terms of color, texture, and date of application. The assessment was conducted throughout visually accessible areas of the subject property. Building materials identified as glass, wood, or metal were not considered suspect ACM.

3.1.2 Physical Assessment

A physical assessment of each homogeneous area of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the EPA as a material, which can be crumbled, pulverized, or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

3.1.3 Sample Collection

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with AHERA sampling protocols. Random samples of suspect materials were collected in each homogeneous area. Bulk samples were collected using wet methods as applicable to reduce the potential for fiber release. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

Terracon collected 65 bulk samples from thirteen homogeneous areas of suspect ACM. A summary of suspect ACM samples collected during the survey is included as Appendix A.

3.1.4 Sample Analysis

Bulk samples were submitted under chain of custody to Eurofins Built Environment Testing East, LLC (Eurofins) in Chantilly, Virginia for analysis by PLM with dispersion staining techniques per EPA methodology (EPA Method 600/R-93/116). The percentage of asbestos, where applicable, was determined by microscopic visual estimation. Eurofins is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP Accreditation No.

600331-0).

3.2 Lead Paint

The lead paint sampling was conducted by Mr. Ryan Nanan of Terracon. Paint chip samples were collected from homogenous painted surfaces identified to determine its lead content, measured by parts per million (ppm). Suspect lead paint samples were collected in general accordance with the EPA’s work practice standards for conducting lead paint activities (40 CFR 745.227). Currently, proposed renovation and demolition activities that could potentially disturb lead paint are subject to the OSHA regulations (29 CFR 1926.62 – Lead).

The lead paint sampling began with the Terracon representative walking the subject structures, observing painted surfaces, and selecting sample locations. After the sampling strategy was determined, Terracon collected eight paint chip samples from homogeneous surfaces.

Paint chip samples were submitted under a chain of custody to Eurofins of Fort Lauderdale, Florida. Paint chip samples were analyzed by Flame Atomic Absorption Spectrophotometry method SW846-3050B/7000B. Eurofins is an American Industrial Hygiene Association (AIHA) Environmental Lead Laboratory Accreditation (ELLAP) accredited laboratory (ELLAP Lab Code 200738-0), to perform Flame Atomic Absorption Spectrophotometry analysis. The lead paint laboratory analytical report is provided in Appendix C.

3.3 PCBs

In addition, Terracon collected eight bulk caulk samples for laboratory analysis of PCBs by EPA Methods 3540C and 8082A. A summary of the PCB in caulk samples collected and the laboratory results are included in Appendix D.

3.4 Universal and Hazardous Waste

Terracon performed a visual assessment of miscellaneous or hazardous materials which may be impacted during the planned demolition/renovation to attempt to identify materials that may impact worker exposure to these materials (OSHA) as well as the potential for waste materials to become a hazardous waste or regulated material with regulated disposal requirements. Testing of the suspect hazardous materials identified was specifically excluded from this assessment. These miscellaneous hazardous or regulated materials may include batteries, mercury-containing equipment, such as thermostats and fluorescent light bulbs, ballasts, fire exit lighting, and smoke detectors.

4.0 Regulatory Overview

4.1 Asbestos

The following sections provide a general overview to the applicable asbestos regulations.

Please refer to the complete current regulation in order to verify compliance before any actions are initiated on an ACM.

March 6, 2026 | Terracon Project No. 34267020

Facilities | Environmental | Geotechnical | Materials 5

4.1.1 NESHAP

The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and asbestos waste disposal practices. The NESHAP regulation also requires the identification and classification of existing ACM according to friability prior to renovation or demolition activity.

Under NESHAP, asbestos-containing building materials are classified as:

1. Friable ACM,

2. Category I Non-Friable ACM, or

3. Category II Non-Friable ACM.

Friable materials are those that, when dry, may be crumbled, pulverized, or reduced to powder by hand pressure. Category I Non-Friable ACM includes packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than 1% asbestos. Category II Non-Friable ACM are any materials other than Category I Non-Friable ACM that contain more than 1% asbestos. Under NESHAP, Regulated Asbestos-Containing Materials (RACM) are classified as:

4. Friable ACM, or

5. Category I Non-Friable ACM that is in poor condition and/or has become friable, or

6. Category I Non-Friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or

7. Category II Non-Friable ACM that has a high probability of becoming or will become crumbled, pulverized, or reduced to powder by the forces expected to act upon the material in the course of renovation or demolition operations.

In the State of Florida, asbestos activities are regulated by the Florida Department of Environmental Protection (FDEP). Some counties have developed an enforcement division to carry out the responsibilities of the FDEP and have developed environmental and asbestos ordinances in which additional compliance is required. Since the facility is located in St.

Lucie County, Florida, the NESHAP regulations are under the jurisdiction of the St. Lucie County Florida Department of Health (561-837-5900).

Per the NESHAP, RACM must be removed prior to renovation or demolition activities that will disturb the materials. Any removal of ACM or RACM must be conducted by a State of Florida-licensed asbestos abatement contractor, in compliance with Florida Statute (F.S) 469.001-014.

Facilities | Environmental | Geotechnical | Materials 6

4.1.2 OSHA

OSHA’s general industry asbestos standard (29 CFR 1910.1001) requires employers to exercise due diligence in complying with the requirements to inform their employees and affected contractors working in the facility about the presence and location of both ACM and materials assumed to contain asbestos.

The OSHA Asbestos standard for construction (29 CFR 1926.1101) regulates workplace exposure to asbestos during construction and maintenance activities. The standard classifies construction and maintenance activities which could disturb ACM and specifies work practices and precautions which employers must follow when engaging in each class of regulated work. States which administer their own federally approved state OSHA programs may require additional precautions.

A full copy of the OSHA asbestos standard for general and construction industry may be found at OSHA’s website (www.osha.gov) and should be referenced for specific information.

4.2 Lead in Construction

Lead is regulated by the EPA, U.S. Department of Housing and Urban Development (HUD), FDEP and OSHA. The EPA and FDEP regulate lead use, removal, and disposal, and OSHA regulates lead exposure to workers. The EPA and HUD, with their small child-safety focus, define Lead-Based Paint (LBP) as paint, varnish, stain, or other applied coating that contains lead equal to or greater than 1.0 mg/cm2, 5,000 ppm, or 0.5% by dry weight as determined by laboratory analysis.

However, for the purpose of the OSHA lead standard, with its focus on the safety/exposure of construction workers, lead-containing paint or LCP includes any detectable concentrations of metallic lead, all inorganic lead compounds, and organic lead soaps. A synopsis of the OSHA regulations (29 CFR 1926.62) and the applicability are as follows:

The OSHA Lead Standard for Construction (29 CFR 1926.62) applies to all construction work where an employee may be occupationally exposed to lead. All work related to construction, alteration, or repair (including painting and decorating) is included. The lead-in-construction standard applies to any detectable concentration of lead in paint, as even small concentrations of lead can result in unacceptable employee exposures depending on the method of removal and other workplace conditions. The OSHA standard requires employee exposure to airborne lead be maintained below the PEL of 50 micrograms per cubic meter of air (ug/m3) over an 8-hour TWA.

Under this standard, construction includes, but is not limited to, the following:

Demolition or salvage of structures where lead or materials containing lead are present

Removal or encapsulation of materials containing lead

March 6, 2026 | Terracon Project No. 34267020

Facilities | Environmental | Geotechnical | Materials 7

New construction, alteration, repair, or renovation of structures, substrates, or portions containing lead, or materials containing lead

Installation of products containing lead

Lead contamination/emergency clean-up

Transportation, disposal, storage, or containment of lead or materials containing lead on the site or location at which construction activities are performed

Maintenance operations associated with construction activities described above

4.3 PCBS

Total PCB concentrations in excess of 50 ppm in caulks and coatings, and adjacent building surfaces (such as masonry) may be considered PCB-contaminated and must be properly managed during renovation and demolition projects under the EPA 40 CFR 761, Polychlorinated Biphenyls (PCBs) Manufacturing, Processing, Distribution in Commerce, and Use Prohibitions regulations. However, applied dried paint and caulking are considered PCB bulk waste products, which may be disposed of in a facility permitted, licensed, or registered by the State as a municipal or non-municipal non-hazardous waste disposal site.

4.4 Universal and Hazardous Waste

Universal waste (UW) are specific hazardous waste streams (batteries, pesticides, mercury containing equipment and bulbs) that a generator can choose to manage in an alternative manner in place of the more complex hazardous waste requirements. These wastes are generated by numerous businesses, typically in small quantities. The Universal Waste Rules (UWR) are intended to promote recycling as well as proper disposal by easing certain regulatory requirements. The federal UWRs are located at 40 CFR 261. Waste must be a hazardous waste before it can be a universal waste. If a hazardous waste stream is not managed as a universal waste, then the waste must be managed as a hazardous waste under the applicable hazardous waste regulations.

It should be noted that any materials resulting from the release or clean-up of spills or breakage of any universal waste is not itself universal waste. It must be determined whether or not such materials are a hazardous waste as identified in 40 CFR 261, and the material must then be managed and disposed of in accordance with applicable hazardous or solid waste regulations.

The potential exists for PCB-containing ballasts that do not have a “No PCBs” label. If ballasts are not marked "No PCBs", they must be treated as containing PCBs. In 1978, EPA issued a ban on manufacturing equipment using PCBs, which most ballasts manufactured before 1978 contained, due to it being hazardous to both human health and the environment.

PCBs are regulated under the Toxic Substance Control Act (TSCA) through the EPA. The EPA regulates the specifics on proper management of PCBs. If the generator determines that the

March 6, 2026 | Terracon Project No. 34267020

Facilities | Environmental | Geotechnical | Materials 8 ballasts do not contain hazardous constituents and do not contain PCBs then they can be disposed of as solid waste; however, they must first be evaluated to determine if they are hazardous. If they are hazardous and will be disposed of, they must be managed as hazardous waste and cannot be disposed of in a solid waste dumpster or landfill. The EPA and state recommendations for management of non-leaking ballasts is recycling. Ballasts that are leaking and are determined, or assumed, to contain PCBs must be disposed properly at an EPA-approved facility.

The potential mercury-containing equipment category was added to the Federal Rule at 40 CFR 273 on August 5, 2005. It includes devices, items, or articles which contain elemental mercury that is integral to their functions, and which would otherwise be regulated as a hazardous waste when discarded by virtue of exhibiting the toxicity characteristic (TC) for mercury (hazardous waste code D009). Some examples of such items include mercury-containing thermostats (formerly a separate universal waste category in the original rule), thermometers, barometers, mercury switches, and certain types of meters, regulators, and gauges, in which elemental mercury is contained in ampules or otherwise enclosed and can be managed intact. This category does not include cathode ray tubes or other types of electronic equipment in which elemental mercury is not integral to function, nor does it include mercury waste that is generated as a by-product through the process of manufacturing or treatment.

4.4.1 Hazardous Waste Disposal

A waste material has the characteristic of “toxicity” if it can leach specific toxic substances into the soil or groundwater. A toxicity characteristic leachate procedure (TCLP) is used to determine the leachability of waste materials.

TCLP testing was not performed as part of our work scope; however, the results of paint testing can be used to determine whether TCLP testing may be needed or not. If analytical results from paint testing are equal to or more than 20 times the TCLP regulatory limit, the waste may be hazardous. Likewise, if the total concentration of a chemical is less than 20 times the TCLP regulatory limit, then the sample is not likely to leach a sufficient quantity of that constituent to exceed the TCLP limit.

5.0 Findings and Recommendations

5.1 Asbestos

Asbestos was not identified in the samples collected during the February 17, 2026, asbestos survey.

If additional suspect materials are found during demolition activities, they should be assumed to contain asbestos until laboratory analysis can confirm or deny their asbestos content. A summary of suspect materials sampled is provided in Appendix A. Laboratory analytical reports are provided in Appendix B. Photographs are provided in Appendix D.

5.2 Lead Paint

Lead was not detected above laboratory reporting limits in the samples collected during this site survey. An analytical summary of the paint chips samples and the laboratory analytical report and chain of custody are included in Appendix C. Representative Photographs are included in Appendix E.

5.3 PCB EVALUATION

Detectable PCB concentrations above the method detection limit were not identified in the 7 collected caulk samples. None of the caulk samples exceeded the regulatory threshold of 50 ppm. Applied dried paint and caulking are considered PCB bulk waste products, which may be disposed of in a facility permitted, licensed, or registered by the State as a municipal or non-municipal non-hazardous waste disposal site.

An analytical summary of the suspect caulk samples and the laboratory analytical report for PCBs is included in Appendices D. Representative photographs are included in Appendix E.

5.4 Universal and Hazardous Waste

Wall thermostats housing mercury-containing switches were not observed during this assessment. No electrical transformers potentially containing PCBs were observed during this assessment. A visual count of light fixtures and light tubes was conducted, and a count of potential mercury vapor-containing fluorescent tubes was obtained. Fixtures were assumed to contain one ballast each, which due to the age of the building are not likely to contain PCBs.

Suspect waste items of concern included:

18 fluorescent light fixtures were observed in each greenhouse unit.

One sunroof motor was observed in each greenhouse unit Two Space heaters were observed in each greenhouse bay Two ceiling mounted fans were observed in each greenhouse bay One wall vent fan was observed in each greenhouse bay Six grow lights were observed in the Clean Greenhouse section of the facility Seven Electrical Panel Boxes were observed in the hallways outside of the greenhouse bays Four fertilizer solution reservoir pumps and irrigation timers were observed in the hallway outside clean greenhouse section of the facility Four LED security light fixtures were observed on the pilot plant and micro-lab building Six fluorescent light fixtures were observed in the pilot plant building Six fluorescent light fixtures were observed in the micro-lab building Four Exit lights were observed in the pilot plant and micro-lab building Two garage door motors were observed in the pilot plant and micro-lab building
