Dear Mr. Lowe:

Hurt & Proffitt, Inc. (H&P) is pleased to provide this document and enclosures as the Pre-Demolition Asbestos-Containing Material and Lead Based Paint Inspection Report, specific to the structure located at 1946 Laurel Valley Road; Troutdale, VA 24378.

Inspection / assessment activities were performed in compliance with United States Occupational Safety and Health Administration (US OSHA) and United States Environmental Protection Agency (US EPA) National Emission Standards for Hazardous Air Pollutants (NESHAPs) on February 27, 2025, by Hurt & Proffitt representative, Mr. Travis J. Wood (Virginia Asbestos Inspector: 3303004688). A copy of Mr.

Wood’s Virginia Department of Professional and Occupational Regulation (VA DPOR) Asbestos Inspector License(s) are enclosed for your review.

1.0 Asbestos-Containing Material (ACM) Survey and Laboratory Procedures

Physical inspection/assessment was performed at the address as referenced above to determine the extent and locations of suspect asbestos-containing materials and potential degree of abatement activities to take place for the proposed demolition.

Suspect bulk samples were collected and logged on chain-of-custody forms as representative of suspect homogenous materials (based on material type, color, texture, etc.), from the functional spaces as they were determined by visual observations in the field.

Five (5) suspect asbestos-containing bulk material samples, including triplicate sets, were submitted for analysis by EPA Method No. 600/R-93/116 and 600/M4-82-020 (polarized light microscopy (PLM)). All samples were analyzed by SanAir Technologies Laboratory of Richmond, Virginia, a NVLAP accredited laboratory licensed to perform asbestos bulk analysis within the State of Virginia.

The following table (Table I) illustrates the sample identification, location, and analytical results as received from the laboratory. A copy of the laboratory results and sample chain-of-custody are additionally enclosed for your review.

Discussion and Recommendations

In order to obtain a building (demolition) permit, this report must accompany the application to the county, town and/or city for which the work is to take place. It is the responsibility of the contractor performing the abatement and/or building demolition activities that the proper permits are obtained and notifications for each type of activity be performed as required by state and federal guidelines.

The facility owner must submit an Asbestos Notification of Demolition and Renovation Form to the VA DOLI along with the appropriate fees within at least twenty (20) calendar days prior to the scheduled demolition start date by certified mail or hand delivery. Notifications should be sent to the following:

Department of Labor and Industry Attn: Accounting / Finance Main Street Centre 600 East Main Street, Suite 207 Richmond, Virginia 23219 Fax: 804.371.7634

Note: A United States Environmental Protection Agency (US EPA) Memorandum dated December 22, 2021, details that complete and timely notifications must be sent to the state or local authority where the work is occurring, however, does not need to be sent to US EPA. This statement applies to any demolition work occurring in Virginia.

Our recommendations are based on the guidelines presented by the United States Occupational Safety and Health Administration (US OSHA), United States Environmental Protection Agency (US EPA), and the Commonwealth of Virginia. Any conditions discovered which deviate from the data contained in this report should be presented to us for our evaluation.

Note: During the process of this inspection/assessment, bulk material sampling was limited to those materials which were safely accessible. As such, additional asbestos-containing materials (ACM) or presumed asbestos-containing materials (PACM) may exist, either undetected and/or inaccessible) within other areas of the structure. If additional suspect materials are discovered during either the asbestos-containing material abatement or demolition activities, all work on the site must stop and the newly identified material(s) sampled by a Virginia licensed asbestos inspector and evaluated for asbestos content.

2.0 Lead-Based (LBP) Survey and Laboratory Procedures

Sample collection was performed by collecting paint chip samples from components identified during the site inspection. The paint chip sample(s) were collected utilizing a manual paint scraper. The removed paint chips were collected in a piece of clean construction paper for transfer into plastic sample collection bags. Each container was sealed and labeled with a unique sample identification number. Pertinent information for each sample including date of collection, location, color, and condition of the surface coatings was recorded on a sampling log form. After sample collection, each sample location was cleaned of extraneous debris.

Three (3) paint-chip samples were collected during the assessment and logged onto chain-of-custody form(s), packaged with custody seals, and delivered by UPS to the analytical laboratory, SanAir Technologies Laboratory, Inc. of Richmond, Virginia. SanAir is licensed by the Commonwealth of Virginia for Lead analysis. SanAir analyzed the paint chip samples for Lead content following EPA’s Method SW 846/3051A/6010B (preparation by microwave-assisted acid digestion followed by analysis via inductively coupled plasma). Analytical results were reported as parts per million (ppm, ug/g) and converted to per-cent Lead by weight. A copy of the analytical laboratory report is enclosed for your review.

The following table (Table No. II) illustrates the analytical results and details regarding the paint chip sample(s) collected during the assessment:

Based upon the results of the laboratory analytical methods, the following paint/surface coatings were identified as lead-based: Door/Framing painted Green.

Discussion and Recommendations

Hurt & Proffitt recommends that the contractor adhere to all applicable United States Environmental Protection Agency (US EPA) regulations regarding disposal requirements and United States Occupational Safety and Health administration (US OSHA) regulations for employee exposure.

Where components tested below the designated action level of 1.0 mg/cm² for classifying the material as lead based paint, it is important to note that any painted or coated surface may contain concentrations of lead, which when disturbed, could generate lead in dust greater than the action level exposure concentration of 30 ug/m3 established by the OSHA “Lead Exposure in Construction Rule” (29

CFR 1926.62).

The OSHA standard gives no guidance on acceptable levels of lead in coatings at which no exposure to airborne lead (above the action level) would be expected; however, OSHA defines airborne concentrations and lists specific work practices which may create a lead hazard. Therefore, personnel exposure monitoring should be performed during any removal or demolition process to establish worker exposure levels which can be used to determine appropriate personnel protection and environmental controls for the specific work practice and material type. In accordance with OSHA requirements, the Contractor performing the work will be required to conduct this monitoring. The primary route of exposure OSHA regulations are concerned with is the inhalation of Lead-containing dust generated by demolition operations within the building. These hazards are assessed by measuring the Lead concentration in air when demolition operations are initiated; a procedure called a negative exposure assessment. The OSHA defined Permissible Exposure Limit (PEL) for Lead is 50 micro-grams (ug) of Lead per cubic-meter (m3) air.

Building demolition and/or renovation activities where LBP is present must comply with the OSHA regulation 29 CFR 1926.62, Lead in Construction; and US EPA waste disposal regulations found in 40 CFR Part 261. OSHA regulations are designed to limit exposure of the construction workforce to Lead, which is a well-documented toxic element.

It would be prudent for the Building Owner to implement and document the following in response to the likely presence of Lead-dust hazards and documented Lead-based paint hazards in the building:

• Prior to any large-scale effort to remove the contents of the building or disturb/demolish building surfaces where LBP is known or suspected to be present, conduct a negative exposure assessment using trained workers wearing respiratory protection and protective clothing in compliance with 29CFR1926.62.

• Notify any person employed by the Owner to work in the building about the potential Lead-dust hazard and the LBP hazards. Instruct such worker in the importance of the use of proper personal hygiene practices and work practices (use of wet methods and HEPA vacuums) by providing them with the EPA-approved pamphlet Renovate Right: Important Lead Hazard Information for Families, Child Care Providers and Schools.

• The US OSHA regulation 29 CFR 1910.1200-Hazard Communication, requires that employers must inform employees about chemical hazards in the workplace. Construction contractors employed to demolish the building components within the site must be furnished a copy of this report.

Waste disposal for concentrated LBP debris (paint chips and scrapings, HEPA vacuum contents, protective suits, drop cloths, etc.) and for building components coated with LBP is regulated under 40 CFR Part 261 and/or 29 CFR 1910.1200. For disposal of construction/demolition debris that contain Lead, the United States Environmental Protection Agency (US EPA) requires the generator perform testing for lead content of the waste stream to determine proper disposal in accordance with the requirements of 40 CFR 261.11, Criteria for Listing Hazardous Waste.

3.0 Limitations

This report summarizes the results of Hurt & Proffitt’s Asbestos-Containing Material and Lead Based Paint Inspection located at the above referenced project based upon our understanding of the requested scope of services. The findings prepared by Hurt & Proffitt are based upon our observations and the analytical analysis of the suspect bulk samples collected at the time of our field inspection. The services performed were provided in accordance with generally accepted environmental industry standard practices. No warranty, expressed or implied, are made. Our observations, conclusions, and recommendations are based upon conditions readily visible at the time of our field inspection, the results of analytical testing, and information provided to us by others.

Our conclusions and recommendations are based upon the guidelines presented to us by the United States Environmental Protection Agency (US EPA), United States Occupational Safety and Health Administration (US OSHA), and the Commonwealth of Virginia. Any conditions which deviate from the data contained within this report should be presented to Hurt & Proffitt for our evaluation and comment. This report has been prepared for the exclusive use of the US Forest Service and/or their agents, as Owner Representative(s).

During Hurt & Proffitt’s inspection, accessible areas were visually assessed for the presence of suspect asbestos-containing materials. Locations and areas reviewed were limited to those identified by the Client and those that could be readily and safely accessed. Our conclusions and recommendations are based on the results of our sampling and analysis activities and cannot be used to form a professional opinion of conditions in other areas beyond those from which the bulk material samples were collected.

It is possible that inaccessible areas, such as inside wall system(s) or substrate finishes, may not have been surveyed and therefore, conditions in these areas are unknown.

During this inspection, suspect asbestos-containing material samples were submitted for analysis at an NVLAP-accredited laboratory via polarized light microscopy (PLM) while suspect lead-based paint samples were submitted for analysis via US EPA’s Method SW 846/3051A/6010B (preparation by microwave-assisted acid digestion followed by analysis via inductively coupled plasma). As with any similar survey of this nature, actual conditions exist only at the precise locations from which the bulk material samples were collected. Certain inferences are based on the results of this sampling and related testing to form a professional opinion of conditions in areas beyond those from which the samples were collected.

Hurt & Proffitt assumes no responsibility regarding response actions initiated as a result of our findings, nor liability for the duties and responsibilities of the Client or Building Owner with respect to compliance with applicable regulations. Compliance with local, state, and/or federal requirements / regulations are the responsibility of the Client or Building Owner.
