Asbestos Inspection Report 873 Pint Circle Longs, South Carolina 29568 Asbestos Inspections, LLC Project # 2023-01-107

Asbestos Inspections, LLC has completed an Asbestos Assessment and Inspection for the structure located at 873 Pint Circle, in Longs, South Carolina. The inspection was completed on April 03, 2023 by a South Carolina Department of Health and Environmental Control (SCDHEC) building inspector.

The following report summarizes the project background, assessment procedures, results, and conclusions. The results presented in this report are indicative of conditions during the time of the inspection and of the specific areas outlined. The information provided in this report should not be used as a bidding document and field conditions should be verified. Should suspect building materials, not included within this report, be identified or impacted during the destructive activities, bulk samples must be collected and analyzed for asbestos content.

I appreciate this opportunity to provide my services. Should you have any questions concerning this report, please contact me at (843) 995-5197.

Sincerely, Asbestos Building Inspector (SCDHEC #BI-00738)

3.0 EXECUTIVE SUMMARY

1.1 Scope and Purpose

Mr. Sam LoFaso with Horry County Government requested this assessment for the structure located at 873 Pint Circle in Longs, South Carolina. Based on information obtained from you, the structure is scheduled for demolition. The purpose of this assessment was to identify asbestos containing materials (ACMs) prior to demolition.

The inspection was completed in accordance with procedures specified in SCDHEC regulation 61.86.1 along with Occupational Safety and Health Administration (OSHA) regulation 29 Code of the Federal Regulations (CFR) 1926. The representative bulk samples collected were analyzed by a National Voluntary Laboratory Accreditation Program (NVLAP) certified laboratory which is administered by the National Institute of Standards and Technology (NIST). This report has been prepared in accordance with Environmental Protection Agency (EPA) 40 CFR, 763.85(a)(4).

2.1 Facility Conditions

The subject structure is an approximately 1700 square-feet, structure that appears to be comprised of two mobile homes joined with additions. The home is very overgrown with vegetation, the roof and ceilings have fallen in, and any accessible floors were in very poor condition and are fallen in as well. The exterior consists of mostly sheet metal walls with wood walls at the addition areas, with an asphalt shingled roof.

The interior was not very accessible; however, we were able to make it partially inside the rear portion as well as at the front door of the front portion. It appears that the interior is mostly wood panelled walls, drywall ceiling, carpeting, and vinyl sheet floor. Every attempt was made to sample all suspect building materials even though the majority of the structure is inaccessible.

Suspect materials sampled during this inspection include sheet floor, mastic, drywall with associated joint compound, shingles, and tarpaper.

The possibility exists that suspect materials were undetected in inaccessible areas such as areas deemed unsafe to enter, underneath or behind contents of units, behind exterior veneer, pipe chases, or wall voids. If additional suspect materials not included in this report are discovered during demolition, bulk samples should be collected and analyzed for asbestos content.

3.1 Findings and Conclusions

The EPA and SCDHEC define materials as asbestos containing if an asbestos content >1% is identified in a representative sample. No asbestos >1% was detected in the following suspect materials collected and analyzed:

Material ID Material Regulatory Result Highest Analytical Result Est. Quantity There are no homogenous materials for this project that have tested positive containing asbestos

A copy of this report along with a demolition application should be submitted to SCDHEC at least 10 working days prior to any demolition activities. Additionally, a copy of this report should be provided to the contractors to assist with compliance with applicable State and Federal regulations.

The results presented in this report are indicative of conditions during the time of the assessment. The information provided in this report should not be used as a bidding document and field conditions and quantities should be verified.

4.0 ASBESTOS ASSESSMENT DATA

The assessment was performed by observing and sampling suspect ACMs in the unit prior to the scheduled renovations. Representative bulk samples were then extracted, recorded on a chain of custody, and submitted to Eurofins/CEI Labs of Cary, North Carolina for laboratory analysis. The samples were tested via Polarized Light Microscopy (PLM); however, SCDHEC requires a Transmission Electron Microscopy (TEM) test be performed for all non-friable organically bound material found negative via PLM.

Dear Customer:

Enclosed are asbestos analysis results for PLM Bulk samples received at our laboratory on April 4, 2023. The samples were analyzed for asbestos using polarizing light microscopy (PLM) per the EPA 600 Method.

Sample results containing >1% asbestos are considered asbestos-containing materials (ACMs) per EPA regulatory requirements. The detection limit for the EPA 600 Method is <1% asbestos by weight as determined by visual estimation.

Thank you for your business and we look forward to continuing good relations.

Due to the limitations of the EPA 600 method, nonfriable organically bound materials (NOBs) such as vinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends that all NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by Transmission Electron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is not covered under NVLAP accreditation. Estimated measurement of uncertainty is available on request.

Dear Customer:

Enclosed are asbestos analysis results for TEM bulk samples received at our laboratory on April 11, 2023. The samples were analyzed for asbestos using transmission electron microscopy (TEM) per Chatfield/EPA 600/R-93/116 Sec. 2.5.5.1 method.

Sample results containing > 1% asbestos are considered asbestos-containing materials (ACMs) per the EPA regulatory requirements. The detection limit for the TEM Chatfield/EPA 600/R-93/116 Sec. 2.5.5.1 method is <1% depending on the processed weight and constituents of the sample.
