Reference: Limited Asbestos Assessment Report

Beaufort County – Sheriff’s Office Warehouse 2727 Depot Road Beaufort, South Carolina High Tide Environmental Project No. 26-2467

Ms. Rodriguez, High Tide Environmental, LLC is pleased to provide you with this limited asbestos assessment report.

The assessment and sampling event was limited to the anticipated areas of renovation associated with the subject facility, as shown in the attached drawing. This report contains a summary of our observations, laboratory results, findings, and recommendations.

PROJECT BACKGROUND & ASSESSMENT METHODS

High Tide Environmental, LLC was requested to perform an asbestos assessment, limited to an interior area of planned renovation within the Beaufort County Sheriff’s Office Warehouse, located at 2727 Depot Road in Beaufort, South Carolina. The area included in the assessment is exhibited in Figure 1, provided as Attachment II. It is our understanding that renovation activities are planned for the subject interior areas.

The purpose of this assessment was to identify the presence of asbestos containing materials (ACMs) associated with the areas of planned renovation. The asbestos assessment aids in the prevention of occupational exposure and environmental releases of asbestos, and aids in compliance with Environmental Protection Agency (EPA) Title 40 CFR, part 61, and State regulation 61-86.1: Standards of Performance for Asbestos Projects enforced by the South Carolina Department of Environmental Services (SCDES, formerly SCDHEC).

Limited Asbestos Assessment Report

High Tide Env. Project No. 26-2647

The subject area currently serves as warehouse space for the Beaufort County Sheriff’s Office and EMS Services. Interior finishes within the subject are consist of concrete floors with limited residual flooring mastic, drywall and wood-paneled walls, and unfinished ceilings with fiberglass insulation. Based on the information provided, the bathroom structure located in the southeast corner of the area will not be disturbed as part of the planned renovations, and was therefore excluded from our assessment. The project area was occupied at the time of our assessment.

The limited asbestos assessment was performed by James McMillan, an SCDES licensed asbestos inspector (BI-01643) on August 4, 2026. Suspect ACMs associated with the areas of anticipated renovation were observed, quantified, and conditions documented. Bulk samples of the suspect ACMs were collected in accordance with EPA Standard 40 CFR 763 Subpart E, Asbestos Hazard Emergency Response Act (AHERA), and the Occupational Health and Safety Administration (OHSA) Standard 29

CFR 1926.1101.

Bulk samples were placed in sealable packages, appropriately labeled, and shipped overnight to a laboratory accredited by the National Voluntary Laboratory Accreditation Program (NVLAP), which is administered by the National Institute of Standards and Technology (NIST). PLM analysis was performed for the samples submitted, which is coupled with dispersion staining in accordance with approved EPA methods. In accordance with SCDES requirements, non-friable organically bound (NOB) materials that exhibit less than one percent (<1%) asbestos content via PLM were subsequently analyzed via transmission light microscopy (TEM) for confirmation analysis. Laboratory results are reported using the specific type of asbestos detected as well as the percentage of asbestos in the material.

The EPA and SCDES define a material as ACM if asbestos is detected at a level greater than one percent (>1%) in any of the representative samples collected.

RESULTS, CONCLUSIONS, & RECOMMENDATIONS

The limited assessment included the bulk sampling and analysis of drywall and associated joint compound, residual flooring mastic, mastic associated with heating, ventilating, and air conditioning (HVAC) ducts, and door/window caulking. Based on the results of the laboratory analysis performed, no asbestos containing materials were identified.

A summary of bulk sample results is provided in Appendix I, which details the sample number, location, type of material, lab result, and approximate quantity. A figure exhibiting bulk sample locations and the area included in the assessment is provided in Appendix II, and a copy of the Inspector’s SCDES License is provided in Appendix III. The laboratory results and chain of custody records are provided in Appendix IV.

If suspect ACMs not addressed as part of this assessment are discovered during planned renovation activities, bulk samples must be collected and submitted for analysis by an SCDES licensed asbestos professional, prior to disturbance.

LIMITATIONS

The assessment was limited to the anticipated areas of renovation, as exhibited in the figure provided in Attachment II, and did not include the entire facility or all observed suspect ACMs or other areas of the subject facility. During the assessment, High Tide Environmental attempted to identify suspect ACMs in readily accessible areas. Inaccessible areas such as wall and ceiling voids, roofing underlayments, and sub-grade areas were not accessed as part of this assessment, and the potential exists for additional suspect materials to be present.

Our observations, conclusions, and recommendations presented herein are based on a reasonable level of assessment in accordance with the industry Standard of Care. High Tide Environmental is not responsible for the hazards that may cause accidents, injuries, or health issues. High Tide Environmental performs assessments based on Local, State, and Federal regulations and guidelines.

EMSL maintains liability limited to cost of analysis. Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations. The report reflects the samples as received.

Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 “Interim Method”) but augmented with procedures outlined in the 1993 (”final”) version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non-friable organically bound materials present a problem matrix and therefore EMSL recommends gravimetric reduction prior to analysis. Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Estimation of uncertainty is available on request.
