EXECUTIVE SUMMARY

This executive summary is intended as an overview for the convenience of the reader. The report should be reviewed in its entirety prior to making any decisions regarding this site.

Terracon Consultants Inc. (Terracon) conducted an asbestos and lead paint inspection, along with a limited mold evaluation, at the Manager’s Residence located on the Lee State Park property at 487 Loop Road in Bishopville, South Carolina. The site consists of one approximately 1,500 square-foot residential building. It was Terracon’s understanding that the South Carolina Department of Parks, Recreation and Tourism (SCPRT) plans to fully renovate the interior of the structure. The purpose of this inspection was to identify and sample suspect asbestos-containing materials (ACMs) that may be disturbed by the planned renovations and provide information regarding the identity, location, condition and approximate quantities of ACM in both interior and exterior building components. The objective of the lead paint evaluation was to identify lead containing paint systems on the building. The purpose of the mold evaluation was to perform visual observations to document conditions, collect surface samples for microscopic examination to document surface fungal growth and collect air samples for total fungal structures at indoor locations and at outdoor locations for comparison.

The inspection was performed on October 7, 2024 by South Carolina Department of Environmental Services (SCDES) licensed asbestos building inspectors in general accordance with Terracon’s proposal P73247217, the sampling protocols established in EPA 40 CFR 763 (Asbestos Hazard Emergency Response Act, AHERA) and the SCDES Regulation 61-86.1 Standards of Performance for Asbestos Projects. Paint samples were collected from visible and accessible building components and paint systems and submitted to an Environmental Lead Laboratory Accreditation Program (ELLAP)-approved laboratory for analysis of lead. Mold samples were submitted to a laboratory accredited by the AIHA Laboratory Accreditation Programs, LLC, for microbial analysis.

Forty-three bulk samples were collected from homogeneous areas of suspect ACM. Four paint-chip samples were collected from the components of the structure on the site. A total of eight fungal samples were collected (five air samples, one blank air sample and two surface samples).

Findings

Asbestos - Based on the results of laboratory analysis, the following materials were confirmed to contain asbestos at concentrations greater than one percent (>1%):

Drywall and joint compound (2% chrysolite) associated with the walls and ceiling systems throughout the building– approximately 3,296 square feet (SF).

Lead Paint – Lead was detected above laboratory detection limits in one of the four paint chip samples collected. The reported concentration did not exceed the SCDES regulatory disposal limit.

Facilities | Environmental | Geotechnical | Materials ii

Mold – Suspect visible fungal growth was noted on the living room closet wall and the hall closet wall and ceiling. Cladosporium fungal growth was confirmed with surface samples.

Air quality in the residence does not appear to be being affected by the sources of indoor fungal growth observed.

Recommendations

Based on the scope of services, limitations, and findings of this assessment, Terracon recommends the following:

The identified asbestos-containing materials should be removed by a South Carolina licensed asbestos abatement contractor prior to renovations that will disturb the ACM.

SCDES requires the building owner to obtain a written project design prepared by a licensed asbestos abatement project designer when 3,000 square feet (or greater) of regulated ACMs are to be removed from a structure.

In accordance with SCDES Regulation 61-86.1, project air monitoring must be performed by a SCDES licensed air sampler in conjunction with the removal of regulated asbestos materials (e.g., friable materials or non-friable materials rendered friable) that exceed the classification of a Small Project or are not regulated exterior removals.

A copy of this report and a project design must be submitted to SCDES at least 10 working days prior to renovation when applying for an abatement permit. Federal, state and local regulations should be referred to in order to verify compliance before any actions are initiated on an ACM.

Inform contractors and workers of presence of lead in paints - Occupational Safety and Health Administration Lead Regulations apply to actions initiated on lead containing materials. This regulation applies to lead concentrations greater than the analytical limit of detection. This regulation provides exposure levels on airborne lead and does not reference the concentration of lead in paint or other lead-containing materials. Workers performing work on surfaces which have any lead concentration should be notified to comply with OSHA requirements. The full OSHA lead standard should be referenced for compliance.

1.0 INTRODUCTION

Terracon Consultants, Inc. (Terracon) conducted an asbestos and lead paint inspection of building materials and a limited mold evaluation at the Manager’s Residence located on the Lee State Park property at 487 Loop Road, Bishopville, South Carolina. The inspection was conducted on October 7, 2024, by a South Carolina Department of Environmental Services (SCDES) licensed asbestos building inspector in general accordance with Terracon Proposal P73247297 dated September 24, 2024.

Terracon understands the asbestos, lead paint, and mold inspections were requested due to the planned renovation of the building.

2.0 BUILDING DESCRIPTION

The Manager’s Residence is a single-story structure on a pillar foundation that measures approximately 1,500 square feet. The building is a wood-framed structure with a pitched shingled roof and wood siding exterior. Floor finishes include carpet and vinyl sheet flooring. Interior walls are finished with painted drywall. Ceilings are drywall and finished with spray-applied texture except in bathrooms and closets. Windows are metal-framed, while doors are wood-framed. The heating, ventilation, and air conditioning (HVAC) system is mounted on the exterior with an air handler in a closet on the porch. The building consists of three bedrooms, two bathrooms, a kitchen, a living room, a dining room, a hallway, and foyer.

A wood-framed shed is located east of the residence. The shed measures approximately 80 square feet with a pitched shingled roof and wood siding exterior. The shed was included in the asbestos and lead-based paint assessment.

3.0 ASBESTOS INPSECTION

The asbestos inspection was conducted by SCDES licensed asbestos building inspectors Mr. Owen Astwood (License No. BI-00475, exp. 11/06/2024) and Ms. Sophia Bradford (License No. BI-002340, exp. 09/10/25). Copies of the inspectors’ asbestos licenses are included in Appendix C. The inspection was conducted on October 7, 2024, in general accordance with the sampling protocols established by EPA Regulation 40 CFR 763 Subpart E 763.86, AHERA and SCDES R61-86.1. A summary of survey activities is provided below.

3.1 Regulatory Overview

NESHAP

Environmental Protection Agency (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 renovation/demolition activities. NESHAP requires that potentially regulated asbestos-containing building materials be identified, classified and quantified prior to planned disturbances or demolition activities. An ACM is defined as any material containing any of the six regulated asbestos minerals in an amount greater than one percent (1%). The asbestos NESHAP regulates asbestos fiber emissions and asbestos waste disposal practices. Under NESHAP, asbestos-containing building materials are classified as either friable, Category I non-friable or Category II non-friable ACM. Friable materials are those that, when dry, may be crumbled, pulverized or reduced to powder by hand pressure. Non-friable materials contain asbestos fibers which have been “locked in” by a bonding agent, coating, binder or other materials so that the asbestos is bound and will not readily release fibers during normal handling or use.

Category I non-friable ACM includes packing materials, gaskets, mastics, resilient floor coverings and asphalt roofing products containing more than 1 percent (%) asbestos. Category II non-friable ACM are non-friable materials other than Category I materials that contain more than 1% asbestos.

Friable ACM, Category I and Category II non-friable ACM which is in poor condition and has become friable or which will be subjected to drilling, sanding, grinding, cutting or abrading and which could be crushed or pulverized during anticipated renovation/demolition activities are considered regulated ACM (RACM). RACM must be removed prior to renovation or demolition activities.

South Carolina In the state of South Carolina, asbestos activities are regulated by SCDES under the SCDES Regulation 61-86.1 Standards of Performance for Asbestos Projects. SCDES requires that any asbestos-related activity conducted in a public building be performed by personnel licensed by SCDES. The owner or operator must provide SCDES with written notification of planned abatement and removal activities prior to the commencement of those activities. SCDES requires four-day notification for non-friable projects and 10-day notification for RACM projects. Asbestos abatement must be performed by SCDES-licensed asbestos abatement contractors. A SCDES-licensed Project Designer shall prepare a written abatement design for each abatement renovation project involving the removal of greater than 3,000 square, 1,500 linear, or 656 cubic feet of RACM. Third-party air monitoring must be conducted during the abatement of friable (regulated) ACM. The SCDES asbestos regulations can be found at https://scdes.gov/environment/your-home/asbestos/asbestos-regulations.

SCDES defines a renovation as “altering a facility or one or more facility components in any way, including the stripping or removal of RACM from any facility component.” A demolition is defined as “wrecking or taking out any load-supporting structural member of a facility together with any related handling operations, the burning of any facility, or moving of a structure.”

OSHA

The Occupational Safety and Health Administration (OSHA) Asbestos Standard for Construction Industry (29 CFR 1926.1101) regulates workplace exposure to asbestos. The OSHA standard requires that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cc). The OSHA standard classifies construction and maintenance activities, which

Facilities | Environmental | Geotechnical | Materials 3 could disturb ACM, and specifies work practices and precautions which employers must follow when engaging in each class of regulated work. A full copy of the OSHA asbestos standard for general industry may be found at OSHA’s website (www.osha.gov) and should be referenced for specific information.

3.2 Prior Report Review

Terracon was not provided with reports pertaining to prior asbestos inspections and/or removal actions for the site.

3.3 Visual Assessment

Terracon’s inspection activities began with visual observation of the interior and exterior of the building to identify apparent homogeneous areas of suspect ACM. A homogeneous area consists of building materials which appear similar throughout in terms of color, texture and date of application. Building materials which were not identified as concrete, glass, wood, masonry, metal or rubber were considered suspect ACM. Although reasonable effort was made to survey accessible suspect materials, additional suspect but un-sampled materials could be located in walls, in voids or in other concealed areas.

3.4 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. Non-friable materials contain asbestos fibers which have been “locked in” by a bonding agent, coating, binder or other materials so that the asbestos is bound and will not readily release fibers during normal handling or use. Friability was assessed by physically touching suspect materials.

3.5 Sample Collection

Based on the results of the visual assessment, bulk samples of suspect ACM were collected in general accordance with the sampling protocols outlined in EPA Regulation 40 CFR 763 Subpart E763.86 (Asbestos Hazard Emergency Response Act, AHERA) and SCDES sample collection 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. The SCDES bulk sampling requirements are defined as follows:

N/A 3

Miscellaneous N/A 3

The selection of sample locations and frequency of sampling was based on Terracon’s observations and the assumption that like materials in the same area are homogeneous in content.

Forty-three bulk samples were collected from 13 homogeneous areas of suspect ACM in the residence and exterior shed. A summary of the suspect ACM samples collected during the survey is presented in Table 1 in the Attachments. Approximate sample locations are depicted on the Sample Location Plan (Exhibit 1) in the Attachments.

3.6 Sample Analysis

Bulk samples were submitted under chain of custody to EMSL Analytical Inc. (EMSL) of Pineville, North Carolina for analysis by Polarized Light Microscopy (PLM) with dispersion staining techniques per EPA EPA/600/R-93/116. The percentage of asbestos, where applicable, was determined by microscopical visual estimation. EMSL is accredited under the National Voluntary Laboratory Accreditation Program NVLAP (#200841-0). Layered analysis of samples was conducted by the lab to separate the layers of vinyl sheet flooring and mastics, and the drywall and joint compound.

In accordance with SCDES Regulation 61-86.1 Standards of Performance for Asbestos Projects, negative results for non-friable organically bound (NOB) materials such as flooring, mastics, and roofing were verified with at least one Transmission Electron Microscopy (TEM) analysis. The additional analysis was performed by EMSL in general accordance with EPA/600/R-93/116 Section 2.5.5.1.

Nine of the sampled materials consisting of 14 layers are considered NOBs and thus were submitted and analyzed via TEM. Samples requiring TEM analysis are identified on Table 1 in the Attachments.

3.7 Findings

The EPA and SCDES define a material as asbestos-containing if the material is determined to contain >1% of any of the six regulated forms of asbestos. Based on the results of laboratory analysis, the following materials were confirmed to contain asbestos at concentrations greater than one percent (>1%):

Facilities | Environmental | Geotechnical | Materials 5

Drywall and joint compound (2% chrysolite) associated with the wall and ceiling systems throughout the residence – approximately 3,296 SF.

Table 1 in the Attachments summarizes the results of the visual inspection, assumptions, estimated quantities, and laboratory analyses. Asbestos laboratory analytical reports are included in Appendix B.

3.8 Recommendations

Based on the scope of services, limitations, and findings of this assessment, Terracon recommends the following:

SCDES requires the building owner to obtain a written project design prepared by a licensed asbestos abatement project designer when 3,000 square feet (or greater) of regulated ACMs are to be removed from a structure.

In accordance with SCDES Regulation 61-86.1, project air monitoring must be performed by a SCDES licensed air sampler in conjunction with the removal of regulated asbestos materials (e.g., friable materials or non-friable materials rendered friable) that exceed the classification of a Small Project or are not regulated exterior removals.

A copy of this report and a project design must be submitted to SCDES at least 10 working days prior to renovation when applying for an abatement permit. Federal, state and local regulations should be referred to in order to verify compliance before any actions are initiated on an ACM.

In accordance with OSHA's Asbestos Standard, the employer shall notify affected employees and contractors of the presence and location of asbestos-containing materials and test results. A full copy of the OSHA asbestos standard for general industry may be found at OSHA’s website (www.osha.gov) and should be referenced for specific information.

It should be noted that suspect materials, other than those identified during the October 7, 2024 inspection may exist within the structures. Should suspect materials other than those which were identified during these surveys be uncovered during or prior to the abatement and renovation or demolition process, those materials should be assumed asbestos-containing until sampling and analysis can confirm or refute their asbestos content. Should future sampling indicate that the other material is asbestos-containing, Terracon recommends removal of the asbestos-containing materials by a licensed asbestos abatement contractor prior to renovation/demolition of the building.

4.0 LEAD PAINT SAMPLING

The objective of the lead paint sampling was to identify lead-containing paint systems on building components that may require special handling and disposal considerations upon renovation of the structure. SCDES regulates solid waste disposal under Regulation 61-107.19 as noted below. Testing

Facilities | Environmental | Geotechnical | Materials 6 was performed to meet specific State disposal requirements and does not comply with all parts of the Occupational Health and Safety Administrations (OSHA) lead regulations. Testing to comply with OSHA regulations are not covered in our scope of work since it is the responsibility of the contractor to protect its employees.

4.1 Regulatory Overview

Lead is regulated by the EPA, SCDES and OSHA. The EPA and SCDES regulate lead use, removal, and disposal, and OSHA regulates lead exposure to workers. The EPA defines lead-based paint as paint, varnish, stain, or other applied coating that contains lead equal to or greater than 1.0 milligram per square centimeter (mg/cm2), 5,000 milligrams per kilogram (mg/kg), or 0.5% by dry weight as determined by laboratory analysis. SCDES Regulation 61-107.19 require that painted demolition debris with a lead concentration greater than 0.06% by weight be disposed in a permitted Class II landfill. For the purpose of the OSHA lead standard, lead includes metallic lead, all inorganic lead compounds, and organic lead soaps. The complete OSHA standard for compliance can be found on OSHA’s website (www.osha.gov). 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 upon on the method of removal and other workplace conditions. 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

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

The U.S. Department of Housing and Urban Development (HUD), SCDES, and EPA require that tenants be notified of the presence of lead-based paint in residential buildings and be provided with a copy of the HUD and EPA pamphlet Protect Your Family From Lead In Your Home. Tenants must also be notified of any renovation activity likely to disturb lead-based paint in their unit or in common areas.

Facilities | Environmental | Geotechnical | Materials 7

4.2 Sampling and Analytical Protocol

Mr. Owen Astwood of Terracon conducted the lead paint sampling on October 7, 2024. The lead paint sampling was conducted by collecting paint chip samples. The paint chip samples were collected from painted or lacquered surfaces of building components likely to contain lead paint, based on apparent date of application. The paint samples were collected down to the surface substrate so as to include any underlying paint systems in the analysis. The random paint chip samples were selected based on current paint schemes and may not be inclusive of old paint systems covered with paneling, or existing painted systems. The paint chip samples were submitted to an ELLAP-approved laboratory for analysis of lead by NIOSH Method 7082M (flame atomic absorption).

4.3 Sample Collection

Four paint samples were collected from interior and exterior painted surfaces on the building. A summary of the lead paint samples is presented in Table 2 in the Attachments.

4.4 Findings

Lead was not detected above the SCDES 0.06% regulatory limit in any of the paint chip samples collected. Lead was detected above the laboratory detection limit in the paint sample from the kitchen door (0.022%).

A summary of the lead paint laboratory results is presented in Table 2 in the Attachments. The analytical report is included in Appendix B.

4.5 Recommendations

Based on the scope of services, limitations, and findings of this assessment, Terracon recommends the following:

Inform contractors and workers of presence of lead in paints - Occupational Safety and Health Administration Lead Regulations apply to actions initiated on lead containing materials.

This regulation applies to lead concentrations greater than the analytical limit of detection.

This regulation provides exposure levels on airborne lead and does not reference the concentration of lead in paint or other lead-containing materials. Workers performing work on surfaces which have any lead concentration should be notified to comply with OSHA requirements. The full OSHA lead standard should be referenced for compliance.

5.0 LIMITED MOLD EVAULATION

5.1 Visual Inspection

A visual inspection was conducted to document existing conditions and areas of impact. The inspection included:

An examination of existing conditions.

An examination for visible evidence of water damage.

An examination for visible suspected fungal growth.

Destructive sampling or testing to inspect interior wall cavity spaces was not within the scope of work for this project.

5.2 Microbial Sampling

There are no State or Federal limits established for fungal growth in, or contamination of building materials. There are currently no regulatory standards, medically based threshold limits, or dose-response relationships for exposure to airborne or surface concentrations of fungal spores. Terracon relies upon experience, professional judgment, current scientific literature, guidelines, and recommendations made by professional organizations and experts in interpreting fungal sampling results.

High variability in airborne fungal spore concentrations can exist in different geographic locations, during different seasons, weather patterns, and over the course of a given day. As a rule, indoor air fungal spore concentrations in ventilated buildings are typically less than, but qualitatively like, fungal spore concentrations found in the outdoor air.

Terracon interprets sample results for airborne fungi by comparing total airborne concentrations and the distributions of fungal genera in samples from indoor locations to samples from outdoor locations. The following comparisons are performed. Other information may be used for interpretation on a case-by-case basis.

In general, total airborne fungal concentrations measured at indoor test locations should be lower than those outdoors.

o If total indoor air fungal concentrations are higher than those measured outdoors, indoor fungal sources may be suspected.

Facilities | Environmental | Geotechnical | Materials 9

In general, airborne fungal genera distributions observed in samples at indoor test locations should be similar as those at outdoor locations.

o The consistent presence of moisture indicator fungi at test locations over and beyond background reference concentrations typically indicates a damp indoor environment.

o The dominating presence of one or more kinds of moisture indicator fungi or fungal spores at test locations and the absence of the same types at background reference locations typically indicates an indoor source and potentially degraded air quality.

Terracon relies on microscopic examination of samples to identify fungal growth on surfaces. Building materials or building surfaces commonly have resident fungal spores that have settled out of the air or have been filtered out of the air with other particles. Fungal structures, such as hyphae and conidiophores (or other fruiting bodies) seen microscopically in surface samples typically indicate fungal growth on surfaces and are associated with the presence of moisture.

Terracon shipped microbial samples under chain-of-custody (COC) protocol to the EMSL Analytical, Inc.

(EMSL) microbiology laboratory in Pineville, North Carolina. EMSL is accredited by the AHIA® Laboratory Accreditation Programs, LLC under the Environmental Microbiology Laboratory Accreditation Program.

5.2.1 Air Samples for Total Fungal Structures

Terracon collected air samples for total fungal structures for microscopic examination using Air-O-Cell® sampling cassettes and a portable sampling pump calibrated at a flow rate of 15 liters per minute, for five minutes. The flow rate was checked prior to the sampling using the factory-supplied rotameter.

Air samples were collected before intensive inspections or measurements, or surface sampling.

5.2.2 Surface Sampling

Terracon collected surface samples for microscopic examination. Samples were collected using EMSL tape samplers. The sample was labeled with a unique identifier, touched to the surface of interest, adhered to a glass slide and then placed into a plastic shipping case. Samples were collected from surfaces exhibiting suspected fungal growth.

5.3 Findings

5.3.1 Visual Inspection

Terracon conducted a visual inspection that began with a walkthrough of the building. At the time of Terracon’s assessment, the HVAC system appeared to be operating normally.

Facilities | Environmental | Geotechnical | Materials 10

Recorded temperatures in the building ranged between 71.4°F and 79°F. Recorded relative humidity (RH) ranged between 47.8% and 69.2%. The calculated indoor dew points were between 52.7 °F and

63.9 °F. Surfaces of some building components, such as HVAC system surfaces, supply air diffusers and nearby surfaces, could be at temperatures at or below the dew point temperature that may allow for condensation of air moisture to occur, although none was observed.

Musty odors were noted in the subject building.

Spots of suspected fungal growth were observed on the walls in the living room closet and on the walls and ceiling of the hallway closet.

Significantly water-damaged or stained materials were not noted in the subject building.

The HVAC return grates in the living room were observed to be dirty and the air filters in the grates were observed to be loaded.

Selected representative photographs are presented in Appendix A.

Exhibit 1 in Appendix B depicts the general layout of the subject building with the approximate locations of the indoor air samples and surface samples indicated.

Outdoor air total fungal spores averaged 28,485 counts per cubic meter of air (counts/m3) and ranged from 23,170 counts/m3 to 33,800 counts/m3 for two samples. The indoor air total fungal structures levels measured were less than the outdoor air average and ranged from 1,970 to 5,990 counts/m3.

The outdoor air Aspergillus/Penicillium average spore concentration for two air samples was 230 counts/m3. Indoor air Aspergillus/Penicillium level in the hall by closet was higher than the outdoor air average with reported concentration of 1,300 counts/m3. The outdoor air Curvularia average spore concentration for two air samples was 140 counts/m3. Indoor air Curvularia level in the master bedroom and living room was higher than the outdoor air average with reported concentration of 420 and 300 counts/m3. The outdoor air Myxomycetes average spore concentration for two air samples was 250 counts/m3. Indoor air Myxomycetes level in the living room was higher than the outdoor air average with reported concentration of 590 counts/m3. The outdoor air Wallemia average spore concentration for two air samples was 0 counts/m3. Indoor air Wallemia level in the master bedroom was higher than the outdoor air average with reported concentration of 300 counts/m3.

The presence of elevated counts of Aspergillus/Penicillium spores in the indoor samples indicates the potential presence of an indoor source. Aspergillus/Penicillium is a common indicator of water-damaged materials. Wallemia is associated with mattresses and the elevated spore count in the master bedroom may be related to its former use. Myxomycetes is associated with rotting lumber and the elevated spore counts may be an indication of damaged subfloor in the residence.

Table 5.2 presents a summary of results for surface samples analyzed by optical microscopy. Two surface samples were collected in the subject building. Surface samples were collected where discoloration or debris indicated suspected fungal growth. The surface samples were collected from hall closet wall and living room closet. The sample was reported to Cladosporium fungal structures. These results indicate fungal growth.

5.4 Conclusions

Terracon has concluded the following based on this assessment:

Suspect visible fungal growth was noted in the living room closet and hall closet wall.

Cladosporium fungal growth was confirmed with a surface sample.

Elevated fungal spore concentrations were reported in indoor air samples collected at the residence. The presence of elevated counts of Aspergillus/Penicillium spores in the indoor samples indicates the potential presence of an indoor source. Aspergillus/Penicillium is a common indicator of water-damaged materials. Wallemia is associated with mattresses and the elevated spore count in the master bedroom may be related to its former use. Myxomycetes is associated with rotting lumber and the elevated spore counts may be an indication of damaged subfloor in the residence.

Air filters located in the ceiling HVAC return grates in the living room were observed to be heavily loaded.

5.5 Recommendations

Terracon recommends the following:

The air filters in the return grates in the living room should be replaced. Air filters in the building should be replaced on a set schedule (e.g., every 30 days) regardless of appearance.

Destructive investigations may reveal the source of the elevated Aspergillus/Penicillium and Myxomycetes spores. The interior of drywall systems and wooden sub-floors and framing should be inspected for the presence of fungal growth.

Visible dust accumulation on HVAC supply diffusers should be periodically removed and cleaned (e.g., vacuumed) to prevent the growth of mold. Condensation and dust accumulation provide an excellent growth medium for molds.

Routinely inspect and maintain ventilation components with special emphasis on drip pans, coils, condensate lines, filters and other moisture contact areas. Supply air diffusers and return grates with visible dust or mold should be periodically cleaned.

Maintain indoor RH levels between 30 and 60% (ideally less than 50%).

6.0 LIMITATIONS / GENERAL COMMENTS

Terracon did not perform sampling which required demolition or destructive activities such as knocking holes in walls, ceiling and dismantling of equipment or removal of protective coverings. Reasonable efforts to access suspect materials within known areas of restricted access (e.g., crawl spaces and attics) were made; however, confined spaces or areas which may pose a health or safety risk to Terracon personnel were not sampled. Sampling did not include materials which could not be safely reached with available ladders.

This inspection was conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions in the same locale. The results, findings, conclusions and recommendations expressed in this report are based on conditions observed during our survey of the building. The information contained in this report is relevant to the date on which this survey was performed and should not be relied upon to represent conditions at a later date.

This report has been prepared on behalf of and exclusively for use by SC Department of Parks, Recreation and Tourism for specific application to their project as discussed. Terracon does not warrant the work of regulatory agencies, laboratories or other third parties supplying information, which may have been used in the preparation of this report. No warranty, express or implied is made.

This report is not a bidding document. Contractors or consultants reviewing this report must draw their own conclusions regarding further investigation or remediation deemed necessary.
