1.0 EXECUTIVE SUMMARY

1.1 PROJECT INFORMATION

Froehling and Robertson, Inc. (F&R) performed a first Limited Hazardous Materials Survey of the Wright

Brothers Memorial Visitor’s Center in Kill Devil Hills, NC on April 24 and 25, 2012; a second investigation was conducted on August 25 and 26, 2015 due to inaccessibility and scheduling. The survey area consists of approximately 9,600 square feet and was originally constructed in the late 1950s. The building is a one-story, reinforced-concrete, steel and glass structure with an asymmetrical plan.

The following is a summary of our findings and is not intended to replace more detailed information contained elsewhere in this report.

Asbestos (2%-50% Chrysotile) was detected in the hot water pipe aircell insulation located in the public restrooms, pipe chase between the public restrooms, Bookstore, Bookstore offices, Bookstore storage closets and Bookstore restroom. The pipe wrap associated with the aircell insulated pipes contained asbestos (2% Chrysotile). Any additional aircell insulation found during renovations should be considered asbestos containing material (ACM). Asbestos (2% Chrysotile) was detected in the plaster within the wire mesh of the flight room soffits and in the exterior Mechanical room ceilings. The exterior transite window panel boards of the bookstore and its adjacent storage room also showed concentrations of asbestos (55%

- 60% Chrysotile) and should be considered as ACM. Mirror mastic in the Bookstore bathroom should be presumed ACM.

In addition to the above identified ACM, F&R recommends that inaccessible building materials listed in

Section 4.1 of this report also be assumed to be asbestos-containing until sampling determines otherwise.

F&R further recommends that a North Carolina Licensed Asbestos Abatement Contractor be engaged to properly remove the asbestos prior to demolition/renovation.

Lead based paint (LBP) was found in several metal door components, baseboards, metal display supports, and metal columns. In addition, the utility sink in the Book Store tested positive for LBP. Should renovations take place that will impact identified lead components, F&R recommends that workers with

Occupational Safety and Health Administration (OSHA) Lead in Construction training be engaged to perform this work.

Mold spore count levels detected inside the lobby area were not elevated when compared to outside background levels. Additionally, the mold genera detected inside the lobby was consistent with the outside mold spore background levels. However, F&R observed water damaged areas on the lobby ceiling.

Reportedly, water leaks are still active in this area and water infiltration occurs from down a column in the

Flight Room during rain events.

1.2 SCOPE OF SERVICES

1.2.1 LIMITED HAZARDOUS MATERIALS SURVEY

The purpose of the Limited Hazardous Materials Survey is to identify regulated materials that require special handling procedures during renovation, demolition, or maintenance of the subject building.

Wright Brothers Memorial Limited Hazardous Materials Survey F&R Project # 66T-0146 September 8, 2015

The Hazardous Materials Survey was limited to the below scope and separated into three parts; an

Asbestos Survey, a Lead Based Paint Screening, and Other Hazardous Materials Survey including polychlorinated biphenyls (PCB)-containing fluorescent light ballasts, mercury-containing thermostats, and mercury-containing fluorescent lamps. Limited mold sampling was performed at the time of the inspection as directed by Hager Smith.

1.2.2 ASBESTOS

A North Carolina Licensed Asbestos Inspector conducted a limited non-invasive survey of the interior and exterior of the subject structure for asbestos containing materials (ACMs).

1.2.3 LEAD‐BASED PAINT SCREENING

A North Carolina Licensed Lead Inspector performed the limited lead based paint (LBP) screening. This investigation was not a comprehensive surface‐by‐surface investigation for LBP, but rather a screening survey of painted surfaces where the presence of lead‐based paint is suspected. A Niton X‐ray Fluorescence

(XRF) Lead Paint Analyzer was used to screen surface coatings that may contain lead.

1.2.4 HAZARDOUS MATERIALS SURVEY

A limited non‐invasive visual survey of the subject building was performed for the identification of potential hazardous materials to include the following: polychlorinated biphenyls (PCB)-containing fluorescent light ballasts, mercury-containing thermostats, and mercury-containing fluorescent lamps.

1.2.5 MOLD

At the time of the inspection, F&R was asked to obtain tape lift samples and spore trap samples (air samples) for mold. The samples were taken at locations as directed by Hager Smith Design personnel.

2.0 METHODOLOGY

2.1 ASBESTOS-CONTAINING MATERIAL (ACM)

A non-invasive visual survey and sampling for suspect ACM were conducted on the interior and exterior of the subject building. The survey was conducted in general accordance with National Emission Standards for

Hazardous Air Pollutants (NESHAP‐40 CFR 61 Subpart M) regulations.

Asbestos bulk samples were packaged, labeled, and submitted for analysis under standard chain‐of‐custody procedures. The samples were submitted to EMSL Analytical, Inc. (EMSL) in Morrisville, North Carolina and analyzed by a trained asbestos analyst using polarized light microscopy (PLM) with dispersion staining techniques. This analytical method is defined in 40 CFR; Part 763, Volume 2.210. EMSL is accredited by the

National Voluntary Laboratory Accreditation Program (NVLAP) and the North Carolina Department of

Natural Resources (NCDENR) to analyze suspect asbestos-containing bulk materials.

A total of one hundred twenty one (121) samples were collected and analyzed for their asbestos content via Polarized Light Microscopy (PLM) following Environmental Protection Agency (EPA) Method 600/R-

93/116.

2.2 LEAD-BASED PAINT (LBP)

A North Carolina Licensed Lead Inspector performed the limited lead based paint (LBP) screening on the interior and exterior of the subject building. A Niton X‐ray Fluorescence (XRF) Lead Paint Analyzer was used to screen surface coatings that may contain lead. A total of seventy seven (77) readings, including calibrations, were collected as part of this screening.

Wright Brothers Memorial Limited Hazardous Materials Survey F&R Project # 66T-0146 September 8, 2015

2.3 POTENTIAL HAZARDOUS MATERIALS

F&R performed a limited non‐invasive visual survey of the subject building for the identification of potential hazardous materials including the following: polychlorinated biphenyls (PCB)-containing fluorescent light ballasts, mercury-containing thermostats, and mercury-containing fluorescent lamps.

2.4 MOLD

2.4.1 SPORE TRAP SAMPLING (AIR-O-CELL)/ANALYSES

F&R performed limited mold air testing to profile the air in the building with regards to fungal air quality.

Samples were obtained from areas as directed by Hager Smith. Elevation of fungal air counts within these areas can be used as an indicator of the possible presence of fungal growth generated by sources of moisture within a building. We note, however, that the absence of elevated counts does not necessarily suggest the absence of moisture damage or lack of fungal growth.

For analysis of airborne fungal spores, samples were collected onto Bioaerosol Sampling Cassettes (Air-O-

Cell™ Spore Trap) cassettes. The samples were collected at a flow rate of 15 liters per minute (Lpm) over a

10-minute period. Analytical data was requested for the total number of spores per cubic meter of air

(count/m3).

Calibration of the sampling equipment was performed with a precision flowmeter (a secondary calibration source). F&R flow meters are calibrated against a primary standard (Dry Cal). Field calibration was performed before and at the completion of sampling. EMSL performed the sample analysis. EMSL is an

American Industrial Hygiene Association (AIHA) Environmental Microbiology Laboratory Accreditation

Program (EMLAP) accredited laboratory for microbial analysis. A total of two (2) spore trap samples were collected and analyzed as part of this investigation.

2.4.2 DIRECT IDENTIFICATION SAMPLING (TAPE LIFT)

Direct tape lift samples were collected from selected areas in the facility which exhibited visible signs of mold growth. Samples were obtained from areas as directed by Hager Smith. The direct tape lift samples were collected by pressing a Zefon Bio-TapeTM Surface Sampler across each of the selected areas. The tape was then affixed to a microscope slide for direct microscopic examination. Each tape sample was placed in a sealed container and the samples were delivered under chain of custody to EMSL for laboratory analysis.

It is important to note that this is a qualitative test to determine the genera of mold present and is only indicative of the location sampled. A total of four (4) tape lift samples were collected as part of this investigation.

Note: There are currently no regulatory standards or guidelines with respect to acceptable microbial levels inside buildings. This data has been interpreted qualitatively using general industry standards and previous experience. In general, industry standards call for inside microbial levels to be less than 25%- 50% of outdoor levels in buildings with mechanically filtered air.

Wright Brothers Memorial Limited Hazardous Materials Survey F&R Project # 66T-0146 September 8, 2015

3.4 POTENTIAL HAZARDOUS MATERIALS

F&R performed a limited non‐invasive visual survey of the subject building for the identification of potential hazardous materials including the following: PCB-containing fluorescent light ballasts, mercury-containing thermostats, and mercury-containing fluorescent lamps.

F&R inspected a representative number of light fixtures for PCB’s. F&R did not observe any Non-PCB labels on the inspected light ballasts, therefore, all ballasts should be considered PCB-containing unless a Non-

PCB label is observed on the ballast.

A total of 32 mercury-containing lamps were identified on the site. One thermostat was observed to be potentially mercury-containing. Mercury lamp components and locations are listed in the below Table.

4.0 CONCLUSIONS AND RECOMMENDATIONS

4.1 ASBESTOS

Asbestos (50% Chrysotile) was detected in the hot water pipe insulation (aircell) located in the Bookstore offices, Bookstore, Bookstore bath, Bookstore storage, Bookstore janitor’s closet, public restrooms, and the pipe chase in the public restrooms. This material was observed in fair condition. Any additional air-cell insulation found during renovations should be considered ACM.

Asbestos (2% Chrysotile) was detected in concrete within the wire mesh of the flight room HVAC panel and in the exterior HVAC room ceiling. The material was observed in fair condition. Any additional concrete on wire mesh found during renovation should be considered ACM.

Asbestos (55%-60% Chrysotile) found in the transite panel board underneath the exterior windows. This material was observed in fair condition.

In addition to the identified ACM, F&R recommends that the following inaccessible building materials be assumed to be asbestos-containing until sampling determines otherwise:

Exterior vapor barrier and associated mastic (not observed during this investigation)

Mastic behind panel walls & Flight Room sign

Vibration dampers

Fire doors Additional site observations include:

Areas behind solid walls and ceilings were inaccessible and could not be visually surveyed for the presence of ACM. ACM including, but not limited to, thermal pipe and pipe fitting insulation may exist in these locations.

F&R recommends that an asbestos abatement specification be developed and incorporated into the overall project prior to renovation and/or demolition of the building.

F&R recommends that an Operation and Maintenance (O&M) plan be developed and implemented to manage all known and suspect ACMs in the building in accordance with 29 CFR 1926.1101 until the building is demolished or all ACMs are abated.

4.2 LEAD-BASED PAINT

Several metal door components, baseboards, metal display supports, and metal columns tested positive for lead-based paint when compared to the HUD action level of 1.0 mg/cm². In addition, the utility sink in the

Book Store tested positive for LBP. Should renovations take place that will impact identified lead components, F&R recommends that workers with OSHA Lead in Construction training be engaged to perform this work.

Wright Brothers Memorial Limited Hazardous Materials Survey F&R Project # 66T-0146 September 8, 2015

4.3 MOLD

Based upon the results of airborne spore count sampling data for the lobby, spore count levels detected inside the lobby area do not appear to be elevated when compared to outside background levels.

Additionally, the mold genera detected inside the lobby were consistent with the outside mold spore background levels.

Several fungal spores, fungal structures, and fungal hyphae were found on the room tape lift samples taken from exterior HVAC room return air duct and the Flight Room active return air duct. The tape lift samples taken from the non-active return air duct in the Flight Room and the office return air show pollen but not fungal spores, fungal structures, or hyphae. The concentration of spores on the tape lifts were in the rare range.

Based upon data obtained from this survey and visual observations, F&R recommends that the owner consult with an engineer or qualified contractor to verify that all sources of moisture intrusion have been identified and corrected. Potential sources for excessive moisture intrusion include, but are not limited to, roof leaks, failing exterior finishes, HVAC imbalances, failing insulation, and/or excessive humidity from other various causes. In addition F&R makes the following general recommendations:

Remove and replace water-stained ceiling tiles.

Maintain HVAC filter changes throughout the building in accordance with the manufacturer’s recommendations.

In general, F&R recommends that the temperature and relative humidity levels inside the building be maintained within the acceptable indoor guidelines as outlined by American Society if Heating Refrigeration and Air Conditioning Engineers ASHRAE.

o Acceptable indoor relative humidity range is 30-60% RH (reference ASHRAE 55-2010).

o Acceptable indoor summer temperature range is 73-79 °F (reference ASHRAE 55-2010).

o Acceptable indoor winter temperature range is 68-74 °F (reference ASHRAE 55-2010).

Due to known historic water intrusion in the building, there is the potential to encounter mold impacted materials during demolition and/or renovation. If during demolition/renovation, contractor personnel observe suspect mold contamination, work should immediately cease in the area until a designated Industrial Hygienist can be contacted to inspect the area. If mold is verified in the work area, the impacted materials should be removed by a qualified contractor using engineering controls prior to recommencing general demolition/renovation work.

Complete remediation of all microbial organisms within a building cannot be guaranteed. It is important to note that the reported mold levels are only reflective of conditions at the time of this test and that mold populations can vary over time, depending upon a number of conditions, including environmental factors (i.e., temperature and relative humidity). Once removed, if significant mold growth reappears, or if the occupants experience prolonged allergic-type health complaints, they should seek further investigation of the problem.

4.4 POTENTIAL HAZARDOUS MATERIALS

4.4.1 MERCURY

A total of 32 mercury containing lamps were identified on the site. One (1) thermostat was observed to be potentially mercury-containing. The mercury containing components should be recycled or disposed of at a landfill where hazardous materials are accepted. The lamps are considered Universal Construction

Wright Brothers Memorial Limited Hazardous Materials Survey F&R Project # 66T-0146 September 8, 2015

Waste. The Universal Waste Rule (EPA UWR) specifically mentions batteries, hazardous waste lamps, mercury containing equipment, and pesticides that are recalled, suspended, or collected for discarding as

Universal Wastes.

4.4.2 PCBS

F&R inspected a representative number of light fixtures for PCB’s. F&R did not observe any Non-PCB labels on the inspected light ballasts, therefore, all ballasts should be considered PCB-containing unless a Non-

PCB label is observed on the ballast.

5.0 APPLICABLE REGULATIONS

5.1 EPA / NESHAP REGULATIONS FOR ASBESTOS CONTAINING MATERIALS

The U.S. Environmental Protection Agency promulgated the National Emission Standards for Hazardous Air Pollutants (NESHAP) [40 CFR Part 61], which addresses the application, removal, and disposal of asbestos-containing materials (ACM). Under NESHAP the following categories are defined for asbestos-containing materials:

Friable - When dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Non-Friable - When dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.

Category I Non-Friable ACM - Packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than 1% asbestos.

Category II Non-Friable ACM – Any material, excluding Category I Non-friable ACM, contains more than 1% asbestos.

Regulated Asbestos Containing Material (RACM) – One of the following:

1. Friable ACM

2. Category I Non-friable ACM that has become friable.

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

4. Category II Non-friable ACM that has a high probability of becoming, or has become, friable by the forces expected to act on the material in the course of demolition or renovation operations.

Under NESHAP, the following actions are required:

1. Prior to the commencement of demolition or renovation activities, the building owner must inspect the affected facility or part of the facility where the demolition or renovation activities will occur for the presence of asbestos.

2. Remove all RACM from the facility before any activity begins that would break up, dislodge, or similarly disturb the material or preclude access for subsequent removal.

3. RACM need not be removed if:

a) It is Category I non-friable ACM that is not in poor condition.

b) It is on a facility component that is encased in concrete or other similar material and is adequately wet whenever exposed.

Wright Brothers Memorial Limited Hazardous Materials Survey F&R Project # 66T-0146 September 8, 2015

c) It was not accessible for testing and was therefore not discovered until after demolition began and because of the demolition the material cannot be safely removed.

d) It is Category II non-friable ACM and the probability is low that the material will become crumbled, pulverized, or reduced to powder during demolition.

5.2 OSHA REGULATIONS FOR LEAD-CONTAINING PAINT

Positive and negative results are based on the US Department of Housing and Urban Development (HUD) Guidelines. It is important to note that if a component is negative based on the HUD standard, it may still contain concentrations of lead in the paint which, when disturbed, may generate lead dust greater than the maximum exposure concentration of 30 micrograms per cubic millimeter 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 paint at which no exposure to airborne lead (above the action level) would be expected.

Rather, OSHA defines airborne concentrations, and references specific types of work practices and operations from which a lead hazard may be generated (reference 29 CFR 1926.62, section d).

Environmental and personnel monitoring should be conducted during any removal or demolition process (as appropriate) to determine actual personal exposure. This monitoring information can be used to determine the levels of personnel protection and environmental controls required for work involving specific removal/demolition processes on specific structures. Under OSHA requirements, the Contractor performing the work will be required to conduct this monitoring and follow all of the other requirements found in 29 CFR 1926.62. It is important to note that environmental controls will vary dependent upon the content of lead in paint, the process used to remove it, duration of the work, and the amount of paint to be removed.

5.3 EPA Regulations for Lead Based Paint Disposal

Based on the levels of lead found on painted building components throughout the property, it is anticipated that these components can be disposed of as non-hazardous waste. However, it is recommended that a Toxic Characteristic Leaching Procedure (TCLP) sample of the waste stream from demolition and renovation activities be collected to determine proper disposal procedures in accordance with Resource Conservation and Recovery Act (RCRA) regulations related to lead. Should painted components from this facility be sent to a recycling facility, this report should be made available to the accepting facility to properly notify them of the lead content of these components. Please note that compliance with RCRA regulations does not relieve the demolition contractor of the OSHA requirements referenced above.

5.4 MOLD

There are currently no regulatory standards or guidelines with respect to acceptable microbial levels inside buildings. This data has been interpreted qualitatively using general industry standards and previous experience. In general, industry standards call for inside microbial levels to be less than 25%-50% of outdoor levels in buildings with mechanically filtered air.

5.5 UNIVERSAL WASTE

The identified mercury containing and PCB-containing components should be recycled or disposed of at a landfill where hazardous materials are accepted. These materials are considered Universal Construction Waste. The Universal Waste Rule (EPA UWR) specifically mentions batteries, hazardous waste lamps, mercury containing equipment, and pesticides that are recalled, suspended, or collected for discarding as Universal Wastes.

6.0 LIMITATIONS

This report has been prepared for the exclusive use of the Hager Smith Design P.A., National Park Service, and/or their agents. This report has been prepared in accordance with generally accepted environmental practices. No other warranty, expressed or implied, is made. Our observations are based upon conditions readily visible at the site at the time of our site visit.

During this study, suspect asbestos samples were submitted for analysis at an NVLAP-accredited laboratory via polarized light microscopy. As with any similar survey of this nature, actual conditions exist only at the precise locations from which suspect asbestos 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. No other warranty, expressed or implied, is made.

Under this scope of services, F&R assumes no responsibility regarding response actions (e.g. O&M Plans, Encapsulation, Abatement, Removal, Tenant Notification, etc.) initiated as a result of these findings. F&R assumes no liability for the duties and responsibilities of the Client with respect to compliance with these regulations. Compliance with regulations and response actions are the sole responsibility of the Client and should be conducted in accordance with local, state, and/or federal requirements and should be performed by appropriately qualified and licensed-personnel, as warranted.

Our observations and recommendations are based upon conditions readily visible at the site at the time of our site visit, and upon current industry standards. During F&R’s inspection, accessible areas were visually surveyed for the presence of suspect lead-based paint (LBP) containing materials. Inaccessible areas, such as behind solid ceilings or behind solid walls were not surveyed, therefore some lead-containing materials may not have been identified. Areas inspected for lead-based paint containing materials were limited to those designated by the scope of services by the Client. As with any similar survey of this nature, actual conditions exist only at the precise locations from which LBP samples were measured. 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. No other warranty, expressed or implied, is made. Individuals who have completed the EPA/State approved lead risk assessor course collected all samples. Lead Dust Wipes and Soil samples were not collected. F&R did not sample drinking water, appliances, or bathroom fixtures as part of the scope of work.

The scope of services performed was limited to those requested by the Client and does not constitute a full microbial assessment of the site or a comprehensive moisture survey of the site. Because of the nature of this type of work (microbial contamination reduction) and the difficulties involved in conducting remediation work, F&R cannot guarantee that the methods or recommendations described in this report will eliminate all microbial contamination within the building, or prevent return of microbial contamination or re-growth under favorable conditions. Since monitoring the performance of the remediation work is beyond F&R's scope of services, F&R also cannot be held responsible for the performance or execution of the remediation work.

It is important to note that microbial levels may fluctuate dependent upon a variety of factors including the weather and time of year. The data provided in this study is only indicative of conditions sampled at the immediate time of the study. Professional services and scientific analyses have been performed, and recommendations prepared in accordance with customary principles in the fields of engineering and analytical science. This warranty is in lieu of all other warranties expressed or implied. The work performed in conjunction with this assessment and the data developed is intended as a description of available information at the dates and locations given. This report does not warrant against future operations or conditions, nor does it warrant against extant, or future, conditions of a type or at a location not investigated.
