Appendix D: Environmental Issues – Survey Reports & Sampling Data

Asbestos-Containing Building Materials

AECOM – formerly URS Corporation – was retained by the Ohio Air National Guard (OANG) to conduct an Asbestos

Survey in support of the planned renovations of Hangar 885, located at 7300 Minuteman Way, on Rickenbacker Air

National Guard Base, Columbus, Ohio 43217.

The objective of this survey was to identify asbestos containing material (ACM) that may be present in the building.

This report summarizes the locations and approximate quantities of the ACM and any presumed ACM (PACM). In addition, an inventory of the regulated materials was conducted.

The asbestos survey and sampling methodologies described in this report were conducted in accordance with:

Asbestos in Buildings: Simplified Sampling Scheme for Friable Surfacing Materials (USEPA, 1985)

EPA Asbestos-Containing Materials in Schools; Final Rule and Notice (USEPA, 1987)

United States Department of Labor Occupational Safety and Health Administration (OSHA) Occupational Exposure to Asbestos; Final Rule (OSHA, 1995)

The scope of services for this asbestos survey consisted of the following tasks:

Perform an asbestos survey to quantify ACM and PACM that were identified in the building. Materials identified as suspect ACM were sampled or presumed in accordance with Asbestos Hazard Emergency Response Act (AHERA) sampling requirements, outlined in Chapter 40 of the Code of Federal Regulations (CFR), Part 763.86. Samples collected were analyzed by a National Voluntary Laboratory Accreditation Program (NVLAP)-accredited laboratory for the presence of asbestos. Samples were analyzed using polarized light microscopy (PLM) by U.S. Environmental

Protection Agency (EPA) Method 600/R-93/116.

Prepare tables indicating sample locations, sample types, analytical results, and/or quantities of ACM and PACM.

Prepare drawings indicating the approximate building configurations, sample locations, and locations of identified

ACM and PACM.

Prepare a summary report that documents the findings of this survey, detailing the items listed above including all supporting documentation, such as the chain of custody and laboratory analytical results.

AECOM’s survey was limited to visual observation and limited destructive sampling and analysis of suspect ACM building materials in various portions of the buildings. However, common construction techniques may render portions of any building inaccessible. As a result, additional asbestos-containing building materials may be present in inaccessible areas of the building that were not observed during the survey.

Therefore, while this Survey was deemed thorough and conducted in accordance with industry standards, it is possible unseen ACM may be present.

The conclusions of this report are AECOM’s professional opinions, based solely upon visual site observations and interpretations of laboratory analyses, as described in this report.

AECOM Page 2

The opinions presented herein apply to the Property conditions existing at the time of AECOM’s investigation and interpretation of current regulations pertaining to asbestos. Therefore, AECOM’s opinions and recommendations may not apply to future conditions that may exist at the Property which we have not had the opportunity to evaluate. Applicable Federal, state, and local regulations should always be verified prior to any work that will disturb materials containing asbestos.

This building survey is not intended to be used as a specification for asbestos abatement activities.

According to the USEPA, a sample indicating an asbestos content of less than or equal to 1% are not considered to be asbestos-containing. All samples indicating an asbestos content of greater than 1% are considered to be ACM.

Per USEPA regulations, a homogeneous area of material must be treated as asbestos-containing if greater than 1% asbestos is identified in any sample of the material.

According to the OSHA, if a sample is found to have any amount of asbestos content, including trace, less than, or equal to 1%, the material is considered to be asbestos-containing. Per OSHA regulations, hazard communication, worker protection, and monitoring requirements apply to this homogenous area of material.

The USEPA identifies three categories of ACM used in buildings; Surfacing Materials, Thermal System Insulation, and Miscellaneous Materials. Descriptions of each material classification are presented in this section.

Surfacing materials include materials sprayed or troweled onto surfaces (walls, ceilings, or structural members) for acoustical, decorative, or fireproofing purposes. This includes plaster and fireproofing insulation. Many of these materials are friable (can be crumbled, pulverized, or reduced to powder by hand pressure), and readily release asbestos fibers.

Thermal system insulation (TSI) is used to inhibit heat transfer or prevent condensation on pipes, boilers, tanks, ducts, and various other components of hot and cold water systems and heating, ventilation, and air conditioning

(HVAC) systems. This includes pipe lagging or wrap (can be chalky material, fibrous material, pressed paper or corrugated cardboard); pre-formed magnesium block, batte (fibers rolled into sheets, usually black or white), and blanket insulation; and cements and "muds" (plaster-like material often used on pipe elbows and other pipe fittings).

Miscellaneous materials include other largely non-friable products and materials such as floor tile and vinyl sheeting, ceiling tile, roofing materials (felt, tar paper, flashing, shingles, and paints), outdoor siding, laboratory hoods and bench tops, chalkboards, wallboard, joint compound, adhesives and taping compounds, putty and caulking, concrete pipe, elevator brake shoes, wire insulation, fabrics (such as fire curtains), duct vibration joint cloth, gaskets, valve packing, and ropes.

Unlike the other two categories of ACM, asbestos fibers in most miscellaneous materials are usually firmly bound in the cement and will be released only if the material is mechanically damaged, for example by drilling, crushing, cutting or sanding.

Hangar 885 was originally constructed in 1954. It is a double-cantilevered hangar structure with central support columns spanning out from the center. There are two aircraft maintenance bays on the flight-line side of this facility. There are several internal structures within the hangar envelope that house administrative space, along with general and specialized shop space. This facility has a high expansion foam firefighting system for the hangar maintenance areas, and it is also interspersed throughout the space. The existing hangar maintenance bays are heated with infrared heaters, and lighted with T-5 fluorescent fixtures.

AECOM conducted an asbestos survey of the property on October 23, 2015. Ohio Department of Health (ODH) licensed inspector Mr. Joel Moore conducted the survey. The AECOM representative has received the following relevant certifications:

• Asbestos Building Inspector Certification

− Mr. Joel Moore, ODH Certified Asbestos Evaluation Specialist (#ES31247).

Inspector certifications for AECOM personnel are included at the end of this Appendix. Supporting documentation for the survey activities described in this report is provided in the Tables and Figures at the end of this report.

The sampling methodologies utilized in this Survey are based on the USEPA guidance document Asbestos in

Buildings: Simplified Sampling Scheme for Friable Surfacing Materials (USEPA, 1985), EPA Asbestos-Containing

Materials in Schools; Final Rule and Notice (USEPA, 1987), and the Department of Labor Occupational Safety and

Health Administration Occupational Exposure to Asbestos; Final Rule (OSHA, 1994).

Suspect ACM was delineated into a homogenous area (HA), which is areas of material that are uniform by color, texture, construction/application date, and general appearance. Each HA was identified by HA and material type.

All “suspect” ACM were either sampled to determine asbestos content or assumed to contain asbestos due to their appearance, age or other qualities. The suspect materials’ characteristics, quantity and locations also were noted.

Samples were collected in a non-abrasive manner by carefully removing small portions of the suspect material with a hand tool suitable to the material being sampled. Each sample was placed in a re-sealable plastic bag immediately after collection for transportation to the laboratory. The sampling instrument was subsequently wiped with a clean moist cloth to decontaminate the tool, prevent the potential release of asbestos fibers, and prevent contamination of subsequent samples.

According to 40 CFR 763.86(a)(4), sampling is not required where an AHERA-accredited Building Inspector has deemed thermal system to be fiberglass, foam, glass, rubber, or other non-ACM (USEPA, 1987).

According to a USEPA letter of interpretation, wood, metal, and glass are identified as non-suspect materials where sampling does not have to be considered (USEPA, 1994A).

According to USEPA letters of interpretation, cinder block, mortar, or brick would not be normally sampled (USEPA, 1994B), and common house paint is not known to contain asbestos (USEPA, 1994A). However, these letters caution that if these materials are suspected of containing asbestos, they should be sampled and analyzed.

Analytical testing of bulk samples was conducted by Optimum Analytical and Consulting, LLC (Optimum Analytical) of Salem, New Hampshire. Optimum Analytical is accredited by the National Voluntary Laboratory Accreditation

Program (NVLAP). Certifications for Optimum Analytical are included this Appendix. A tabular summary of the bulk sample results is included in Table 1 which is located in the Table section of this report. The analytical results are included this Appendix.

Bulk samples of suspect materials were first examined for homogeneity, the presence or absence of fibrous constituents, the preliminary identification of fibers, and an estimate of fiber content at low magnification.

Following this, the Polarized Light Microscopy (PLM) method with dispersion staining (per EPA Method 600/M4-

82-020) was applied. The identification of asbestos fiber bundles was then determined by the visual properties displayed under a light microscope equipped with polarizing filters. A visual estimation was made of the percent area occupied by each type of asbestos fiber. Multi-layered materials were analyzed per layer to determine asbestos content. Typically if the PLM visual estimation method identified an asbestos content of less than 10%, the PLM point count method of analysis was then applied for a greater degree of accuracy. The lower detection limit of the PLM point count method is less than 1%.

AECOM Page 4

Samples containing trace amounts of asbestos were only estimated to contain ≤ 1% asbestos and were not point counted to more accurately define the asbestos content. Therefore, materials containing trace amounts of asbestos were presumed to be ACM.

During the survey, AECOM collected a total of 27 bulk samples. Five of the building materials sampled during the survey were positively identified as Regulated ACM or PACM based on the laboratory analysis.

It should be noted that any samples collected from the hangar should be excluded in regards to future renovations. This portion of the facility is not included in the scope of work for renovation. Also, floor tile found in rooms 109, 111 and 112 are similar to the floor tiles and mastic in room 146 and are characterized as ACM.

Laboratory analysis revealed building materials at the Property containing regulated quantities of asbestos (see

Table 1 of this Appendix).

ACM identified may be impacted by renovation or demolition activities at the Property. Therefore, all impacted

ACM within the renovation or demolition area should be removed and disposed of in accordance with Federal, State, and local regulations, prior to disturbance. Abatement of the ACM must be performed by a licensed asbestos-abatement contractor.

Contractors should use caution during renovation even after asbestos abatement activities, as concealed ACM that has not previously been analyzed for asbestos may be encountered. ACM may be located between walls, above ceilings, in pipe chases, or other inaccessible areas. If suspect ACM located in accessible and/or inaccessible areas of the building are encountered during renovation or demolition activities, further sampling will be required to characterize those materials.

Lead-Based Paint

AECOM also investigated for the presence of lead-based paints (LBP) on structural members and other building surfaces. Samples were collected from the steel structural members, walls in the stairwells, and walls in rooms and the hangar. Paint found on the steal structural beams contains lead at 10-14%. Paint found on the walls contains lead at <0.01% to 0.89%. Laboratory analysis is included this Appendix.

Table 2 – Lead Paint Sampling Data

Sample Number Location Per cent lead Lead Content (PPM)

885-PB-01 Steel beams above hangar 14% 140,000

885-PB-02 Steel beams above hangar 10% 100,000

885-PB-03 Room 205 walls 0.89% 8,900

885-PB-04 Stairwell <0.01% <100

885-PB-05 Hangar walls <0.01% <100

Currently, there are no regulatory requirements to remove or otherwise abate LBP in non-residential structures prior to demolition or renovation. However, any planned renovation work (e.g., manual demolition of or modifications to building components coated with LBP or the preparation of LBP surfaces for repainting) must be conducted in accordance with all applicable requirements of the OSHA lead standard (29 CFR 1926.62). The OSHA standard has specific training requirements and work practices for work involving the disturbance of LBP.

OSHA does not define lead-containing paint or materials or specify a lead content for materials that could cause occupational exposure to lead above permissible exposure limits. Maintenance, renovation or demolition work with any lead-containing material that will be disturbed during construction activity has the potential to cause occupational exposure to lead. OSHA requires that specially trained and equipped workers utilizing controlled methods of removal conduct any demolition/renovation of building components coated with LBP. Workers disturbing the surfaces of LBP-coated building components, as part of renovation work must comply with applicable requirements of the OSHA lead in construction standard. This regulation applies to all construction work where any employee may be occupationally exposed to lead. This includes demolition of structures where lead-containing materials are present, and removal, new construction, alteration or renovation of structures or substrates that contain lead.

The applicability of specific sections of the standard and the need to comply with specific requirements depend on the actual levels of exposure that employees experience when performing construction activities in or on buildings where lead-containing materials are present. Therefore OSHA requires [per 1926.62 (d)(1)] that each employer performing operations covered by this standard conduct exposure assessments to determine if there employees are exposed to lead above the action level (30 ug/mg ) or the permissible exposure level (PEL) (50 ug/mg

). Worker exposures above the action level and PEL trigger specific actions that each employer must take to control and limit exposures to lead.

Until the employer performs an employee exposure assessment as required under paragraph (d) and determines actual employee exposures, the employer is required by law [per 1926.62 (d)(2)(v)] to provide employees performing these construction activities with interim protection as described below:

AECOM Page 7

• Appropriate respiratory protection in accordance with paragraph (f) of the standard (i.e., half-mask, air-purifying, properly fitted respirators equipped with high-efficiency particulate filters).

• Appropriate personal, protective clothing and equipment in accordance with paragraph (g).

• Change areas in accordance with paragraph (I)(2).

• Handwashing facilities in accordance with paragraph (I)(5).

• Biological monitoring I accordance with paragraph (j)(1)(i), to consist of blood sampling and analysis for lead and zinc protorphyrin levels.

• Training as required under paragraph (l)(1)(i) of the standard regarding 29 CFR 1926.59, Hazard

Communications; training as required under paragraph (l)(2)(ii)(C) of the lead standard regarding the use of respirators; and training in accordance with 29 CFR 1926.21, Safety Training and Education.

According to OSHA, these interim protection requirements apply to any employee engaged in any construction activity with the potential for lead exposure until the employer performs an employee exposure assessment and documents that the employee’s lead exposure is not above the action level or PEL. Alternatively, employers may rely on previous monitoring data to satisfy the OSHA monitoring requirements. This data must have been obtained within the past 12 months from work operations conducted under essentially the same workplace conditions with similar materials, control methods and work practices.

Manual demolition of concrete-block walls coated with paint that contains relatively low levels of lead (<5000 ppm as determined by AAS or ICP analysis, or <0.1 mg/cm as determined by XRF) is not likely to generate exposures to lead above the OSHA PEL or action level.

Torch cutting or welding on LBP coated surfaces or surfaces coated with paint containing low levels of lead can generate significantly higher personal exposures to lead. If renovation plans call for torch cutting or welding of painted metal surfaces, AECOM recommends that an experienced abatement contractor removes the LBP from the areas of the metal to be cut prior to the torch cutting.

Chemical paint removal would be a suitable approach for abating LBP identified on the painted metal surfaces that must be welded or torch cut. However, this abatement method is labor-intensive process that utilizes chemical agents that often require multiple steps of application and removal. Some chemical stripping methods also generate special wastes or possible hazardous wastes. The unit cost for chemical removal of LBP from metal surfaces ranges from $10 to $18 per square foot.

Lead abatement activities (stripping or replacement) should be conducted (if deemed necessary) by a qualified lead abatement contractor, who is trained and knowledgeable of all requirements of the OSHA lead standard.

Typically, the abatement contractor performs the LBP abatement work, cleans up and arranges for disposal of waste materials. A qualified environmental consultant typically performs clearance testing, testing and characterizing waste streams and compliance evaluations. It is recommended that a qualified inspector, industrial hygienist or local public health official conduct on-site surveillance of the contractor to ensure the complete and proper removal of the LBP.
