Environmental Investigation Services Report for Building 50, Fort Leavenworth, Kansas

1.0 INTRODUCTION

Tehama, LLC (Tehama) has performed a full interior and exterior inspection for the presence or absence of Asbestos-Containing Materials (ACM), for Building 50 at Fort Leavenworth, Kansas. The inspection was conducted at the request of Yaeger Architecture, Inc. (Yaeger) for use in their design-build package for renovation of Building 50. The scope of work for this project was based on Yaeger’s scope of work, drawings and emails, and Tehama’s proposal dated September 6, 2017. The intent of this inspection was to locate, identify and quantify ACM that will be impacted during the upcoming renovation project.

Anne Eiseman, a certified Environmental Protection Agency (EPA) Asbestos Hazard Emergency Response Act (AHERA) Asbestos Inspector with Tehama, performed the inspection on October 18th, 2017. Anne Eiseman and Jerrett Domling, also a certified EPA AHERA Asbestos Inspector with Tehama, returned to Building 50 on November 15th, 2017 to inspect the crawl space. Certifications for inspectors are located in Appendix A.

2.0 FIELD INVESTIGATION PROCEDURES AND SAMPLE ANALYSIS METHODS

Guidelines used for the inspection were established by the EPA in the “Guidance for Controlling Asbestos Containing Materials in Buildings”, 40 CFR 763, 29 CFR 1926.1101, 40 CFR 61, 29 CFR 1910.134, AHERA, National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations, and where applicable Kansas Statutes Annotated (K.S.A Chapter 65, Article 53), Kansas Administrative Regulations (K.A.R. 28-50-1 to 28-50-14).

Field information was organized in accordance with the AHERA methodology of homogenous area (HA).

A HA contains material that is uniform in texture and color and appears to be identical in every other respect. Building materials that were installed at different times or that do not appear to be similar in any other way are considered separate homogenous materials/areas. Bulk sampling for each HA was completed and specific sampling locations were chosen at random.

All bulk samples were sent to EMLab P&K and analyzed by Polarized Light Microscopy (PLM) coupled with dispersion staining techniques as outlined in the EPA 600/R-93/116 Method. The laboratory provides the approximate percentage of asbestos fibers in the sample and also identifies the crystal form of the asbestos. The EPA considers materials to be ACM if they contain greater than one-percent (1%) asbestos fibers. Occupational Safety and Health Administration (OSHA) regulations cover materials containing asbestos in any concentration.

The EPA considers the following materials to be non-suspect ACM, and consequently, they were not sampled:

• Glass • Fiberglass

• Metal • Rubber

• Concrete

• Brick

Tehama subcontracted laboratory analysis procedures to EMLab P&K located at 10900 Brittmoore Park Drive, Suite G, Houston, Texas 77041. The laboratory maintains accreditation from the following agencies:

• National Voluntary Laboratory Accreditation Program (Lab Code 600122-0)

• American Industrial Hygiene Association Accredited Laboratory (Lab No. 193549)

Laboratory certifications are presented in Appendix B of this report.

3.0 INSPECTION SCOPE AND MATERIAL ASSESSMENT

This survey was conducted to determine whether asbestos is present in interior and exterior areas of the building, in preparation for building renovation activities. The sampler’s discretion was used for determining the number of samples to be taken of suspect ACM in each HA.

A total of 62 bulk samples were collected from suspect ACM during the survey at Building 50. Bulk sample locations are presented on Figures 01 through 03 in Appendix C of this report.

4.0 INSPECTION RESULTS

Analytical results of the bulk samples collected indicate that the following materials contain greater than 1% asbestos and are considered ACM:

• Non-Friable 12x12 Beige Floor Tile

• Non-Friable 12x12 Light Brown Floor Tile

• Non-Friable 12x12 Green Floor Tile with Black Mastic

• Non-Friable 12x12 Off-White Floor Tile

• Non-Friable 12x12 Eggshell Floor Tile (Floating Floor)

The following table details the locations and quantities of the ACM identified:

ACM Material Location Quantity 12x12 Beige Floor Tile Entry 2 225 ft2 12x12 Green Floor Tile with Black Mastic Offices (3, 4, 9, and 10) 920 ft2 12x12 Off-White Floor Tile Offices (6, 11, 13, 14), Hall (1, 2, 4), Docking Area, Wash Room (Next to Men’s Restroom on Top Floor), Conference Room, West Entry

2,560 ft2

12x12 Eggshell Floor Tile (Floating Floor) Main Office and Basement Crawl Space 2,000 ft2

Complete laboratory analytical results are presented in Appendix D. No photographs were taken due to security restrictions within the building.

5.0 CONDITION AND FRIABLITY ASSESSMENT

For each inspection conducted, the inspector classifies ACM materials by friability and condition. This helps to determine the extent of damage in certain areas as well as the potential for further damage and asbestos release due to disturbance of the material.

All positive materials appeared to be in good condition, meaning there was no apparent damage to ACM.

6.0 AREAS NOT ACCESSIBLE

Void Spaces within Walls and Ceilings: No destructive sampling was performed on concealed spaces on walls to access plenum or chases. Due to the nature and outcome of the materials sampled Tehama did not observe any “suspect” materials continuing into plenums, etc. Tehama cannot account for all plenums/void spaces that exist in these facilities without selected demolition of existing walls, floors, ceilings, etc.

Tehama recommends periodic oversight during demolition in order to assess any hidden/unforeseen materials that might be revealed.

7.0 POLYCHLORINATED BIPHENYLS

Polychlorinated biphenyls (PCBs) are regulated pursuant to the United States Environmental Protection Agency Code of Federal Regulations (40 CFR 761) and the Toxic Substances Control Act (TSCA – 15 U.S.C. 2605).

These regulations require certain testing and reporting requirements to determine management, recycling and disposal options for PCBs. Please see the below table itemizing the number of assumed PCB-containing Fluorescent Lighting Ballasts:

At various locations within the building, Tehama noted other wastes that could potentially be considered hazardous if disposed of incorrectly. The following is a list of materials observed:

• 2-Gallon Pesticide Bottles in Mechanical Room (Approx. 10)

• 1 lb. Propane Bottles Scattered throughout Mechanical Room (Approx. 5)

• 32 oz. Bottles of Cleaning Supplies in Restrooms and Docking Area

• 2-Gallon EvapPow’r-C Coil Cleaning Product in Crawl Space

• 5 lb. compressed air cylinders: Oxygen (2) and Acetylene (2) in Mechanical Room

9.0 CONCLUSIONS AND RECOMMENDATIONS

Multiple forms of ACM have been identified that will be impacted by the renovation project in Building

50. These materials, reported in Section 4.0 of this report, will require complete abatement prior to the start of the renovation project as per all federal and state regulations.

The asbestos inspection was based on the scope of work proposed by Yaeger for use in their design-build project. Any change in the scope of work beyond what was identified in the scope of work drawings and subsequent emails will require further investigation to accurately classify any additional ACM/Hazardous Materials resulting from the modified or updated scope of work.

SECTION II

LEAD-BASED PAINT (LBP)

1.0 INTRODUCTION

Tehama has performed a full interior and exterior inspection for the presence or absence of Lead-Based Paint (LBP) for Building 50 at Fort Leavenworth, Kansas. The scope of work for this project was based on Yaeger’s scope of work, drawings and emails, and Tehama’s proposal dated September 6, 2017. The intent of this inspection was to locate, identify and quantify LBP that will be impacted during renovation of the building.

Inspectors Megan Perez-Utter and Anne Eiseman performed the inspection from October 18 – 19, 2017.

Megan Perez-Utter and Anne Eiseman are certified Lead Inspectors by the Kansas Department of Health and Environment. Certifications for inspectors are located in Appendix A.

2.0 FIELD SURVEY PROCEDURES AND SAMPLE ANALYSIS METHODS

The purpose of the LBP survey was to conduct a surface-by-surface investigation of painted components inside and outside of the building in an effort to identify which painted surfaces contain lead.

Some of the test locations exhibited lead-in-paint levels below the level that EPA identifies as LBP, specifically 0.5% by weight or 1.0 mg/cm2. Such surfaces could create dust-lead or soil-lead hazards if the paint is turned into dust by abrasion, scraping, or sanding. Should these or any lead containing components or surfaces be disturbed in any manner that generates dust, care should be taken to limit worker exposure and the spread of dust.

The lead regulatory levels provided below are those used when preparing this LBP evaluation or when evaluating data collected. The EPA regulatory levels are the same as the state regulatory levels provided in the following table:

EPA Levels

Lead-Based Paint

1.0 mg/cm2 or 0.5% by weight (or 5,000 pm)

Testing was accomplished through the use of an Olympus DELTA Series handheld x-ray fluorescence (XRF) to collect lead levels on painted surfaces. The XRF determines the chemistry of a sample by measuring the fluorescent x-rays emitted from the sample that returns to the XRF after irradiated energy is released onto the sample. A total of 273 XRF tests were performed on different paint variations on the interior and exterior of the structures. Field validation checks of the XRF were also performed at the beginning and end of test operations on the day of testing. Validation checks were performed through a series of three tests on a NIST SRM paint film. Results of the validation checks indicated that the XRF unit was calibrated properly.

Tehama also collected paint chip samples that were submitted to the subcontracted laboratory, EMSL Labs, to compare concentrations with field XRF readings. All samples were analyzed by Flame Atomic Absorption as outlined in NIOSH 7082 Pb-FLAA Method. EMSL is located at 3029 South Jefferson, St.

Louis, MO 63118. The laboratory maintains accreditation from the following agencies:

• National Voluntary Laboratory Accreditation Program (Lab Code 200742-0))

• American Industrial Hygiene Association Accredited Laboratory (Lab No. 102636)

Laboratory accreditations are presented in Appendix B of this report.

3.0 SUMMARY OF INSPECTION

A visual assessment of each unique combination of suspect LBP was completed. Unique sampling combinations of suspect LBP were then analyzed using a handheld XRF. The inspection was characterized by observations of accessible areas.

XRF results indicated that the following materials contained LBP greater than or equal to 1.0 mg/cm2:

• Green Metal Railing- Interior

• Green Wood Stairs- Interior

• Yellow Metal Sink- Interior

• Green Wallpaper– Interior

• White Wallpaper- Interior

• Tan Metal Railing- Interior

• Tan Wood Stairs- Interior

• Red Metal Railing- Exterior

• Red Metal Support Beam- Exterior

• White Metal Dock- Exterior

4.0 INSPECTION RESULTS

The LBP inspection involved a thorough visual examination of accessible areas, field XRF testing of painted surfaces, and laboratory analysis of select paint chips. XRF results presented in Appendix D of this report provide information on test locations, substrate tested, condition of paint, and concentration.

Inspection locations with lead are detailed on Figures 04 through 06 located in Appendix C of this report.

In total, two paint chip samples were collected and analyzed, of which both tested positive for LBP. Painted surfaces where chip samples were collected were found to be in fair condition as defined by the EPA and Housing and Urban Development (HUD) guidelines. In general, the paint chip samples correlated well with concentrations taken by XRF, indicating the XRF was working properly.

Some of the test locations exhibited lead-in-paint levels below the level that EPA identifies as LBP, specifically 0.5% by weight or 1.0 mg/cm2. Such surfaces could create dust-lead or soil-lead hazards if the paint is turned into dust by abrasion, scraping, or sanding. Should these or any lead containing components or surfaces be disturbed in any manner that generates dust, care should be taken to limit worker exposure and the spread of dust.

5.0 CONCLUSIONS AND RECOMMENDATIONS

Any work which disturbs painted surfaces containing lead shall be performed in accordance with the OSHA, 29 CFR 1926.62 (Lead in Construction Standard) and EPA’s 40 CFR 745 regulation. Personal air monitoring should be conducted when disturbing lead based paints and lead containing materials as per 29

CFR 1926.62 (OSHA).

In addition, all waste generated as part of the project, regardless of the lead content in the paint, shall be tested in accordance with the EPA Resource Conservation and Recovery Act (RCRA) to determine the classification of the waste. Under RCRA, any waste material that when tested by Toxicity Characteristics Leaching Procedure (TCLP) results in a leachate lead concentration of five (5) parts per million or greater must be disposed of at an EPA licensed hazardous waste facility.

6.0 LIMITATIONS, EXCEPTIONS AND ASSUMPTIONS

Opinions and recommendations presented in this report apply to site conditions and features as they existed at the time of Tehama’s site visit, and those reasonably foreseeable. They cannot necessarily apply to conditions and features of which Tehama is unaware and has not had the opportunity to evaluate.

Tehama has completed a thorough assessment of each unique painted surface within the interior and exterior areas of the buildings. If a different painted surface is identified during demolition that has not been tested, it should be assumed positive for LBP. Additional testing may be completed to determine the presence or absence of LBP.

The conclusions presented in this report are professional opinions based solely upon Tehama’s visual observations of accessible areas, laboratory test data, and current regulatory requirements. These conclusions are intended exclusively for the purpose stated herein, at the site indicated, and for the project indicated.

SECTION III

MICROBIAL SURVEY

1.0 INTRODUCTION

This report documents the findings, opinions, and conclusions of an indoor air investigation of Building 50 located at Fort Leavenworth, Kansas. The scope of work for this project was based on Yaeger’s scope of work, drawings and emails, and Tehama’s proposal dated September 6, 2017.

Ongoing issues with water infiltration and flooding have been documented in the building; therefore, a microbial survey was conducted to identify the types and concentrations of mold present within the structure.

2.0 METHODS AND SAMPLING

Five samples were collected, with four being collected inside and one being collected outdoors as a background sample. The four indoor sampling locations were located in the basement and on the first floor, with one on each side of each floor. The samples were collected using a 12 liter-per-minute pump and a 0.45 micron polycarbonate filter, with a 10 minute duration for each sample. Each filter was then labeled with an identification number, documented on a chain-of-custody form, and submitted to the laboratory for analysis. The samples were submitted ALS Environmental, an American Industrial Hygiene Association (AIHA) Industrial Hygiene Accredited Laboratory. Speciation was completed by Deoxyribonucleic acid (DNA) detection using the quantitative polymerase chain reaction (QPCR) method. Laboratory certifications are presented in Appendix B and analytical reports are presented in Appendix D.

3.0 MICROBIAL SURVEY DATA ANALYSIS AND INTERPRETATION

This section discusses the interpretation of the data. The results of the laboratory data are provided in Appendix D.

Microbial sample results for fungi and endotoxins within Building 50 are presented in Table 2 below:

Table 2 - Fungal and Endotoxin Concentrations

Sample Number and Location Fungal Concentration Spore Count/m3

FLW-50-1 – Office 2 1,700 FLW-50-2 – Hall 5 700 FLW-50-3 – Hall 6 1,500 FLW-50-4 – Outside Office 34 5,200 FLW-50-5 – Outside Front Entryway – Background Sample 5,900

OSHA has not established regulatory threshold values for fungal concentrations for worker protection. The American Conference of Governmental Industrial Hygienists (Air Sampling Instruments for Evaluation of Atmospheric Contaminants 1995) recommends the following guidelines: 100 colony forming units (cfu) or less per cubic meter of air indicates low risk. An intermediate risk is indicated by 100 cfu to 1000 cfu per cubic meter of air, while 1000 or more cfu per cubic meter of air indicates a high risk.

The National Institute for Occupational Safety and Health (NIOSH), ASHRAE, and EPA all agree that while associations between mold and adverse health effects have been observed, relationships between microbial exposure, and health effects cannot be measured. However, it is believed the most effective course is to limit the potential for microbial growth indoors by reducing the causes of persistent dampness.

Labortatory analysis of fungal samples indicates that various types of mold exist within Building 50. The following discussion describes the types of mold identified and their hazards to human health:

• Alternaria:

o Type I allergies (hay fever, asthma) and a Type III hypersensitivity pneumonitis:

Woodworker's lung, Apple store hypersensitivity. (EMLab P&K).

o Toxin Alternariol (used as an antifungal) produced by A. alternata. Other metabolites produced include AME (alternariol monomethylether), tenuazonic acid, and altertoxins (mutagenic).

o Presents unique human risks (as pathogen, opportunist or contaminant). It can affect respiratory system, skin, and nails. Presents greatest risk to immunosuppressed and wound injury individuals.

• Ascospores:

o Considered to be an allergen.

o Can produce toxins, dependent upon genus and species.

o Presents a human health risk but few have been reported to cause disease.

• Aspergillis/Penicillium:

o Type I allergies (hay fever, asthma) and a Type III hypersensitivity pneumonitis:

Humidifier lung, Malt worker's lung, Compost lung, Wood trimmer's disease, Straw hypersensitivity, Farmer's lung, and Oat grain hypersensitivity.

o Can produce mycotoxins, however these are often found in contaminated food and are hazardous to the consumer.

o Potential pathogen for respiratory, invasive, cutaneous, ear, and corneal diseases. Severe, invasive disease is usually associated with immunosuppressed hosts. Many species grow at 37°C (body temperature).

• Basidiospores:

o Acts as an allergen. Some people may experience hay fever, asthma, hypersensitivity pneumonitis: cheese washer's lung, woodman's lung, moldy wall hypersensitivity.

o Produces toxins and poisoning is usually a result of ingestion of the following toxins:

amanitins, monomethyl-hydrazine, muscarine, ibotenic acid, psilocybin.

o It is rare that this mold is a pathogen that presents risk to humans.

• Bipolaris/Drechslera:

o Type I allergies (hay fever, asthma).

o Most commonly reported cause of allergic fungal sinusitis.

• Cladosporium o Common and important allergen. Type I allergies (hay fever, asthma) and Type III hypersensitivity pneumonitis: Hot tub lung, Moldy wall hypersensitivity.

o Toxins produced are not highly toxic, cladosporin and emodin.

o Not a human health risk.

• Curvulaira:

o Type I allergies (hay fever, asthma).

o Most commonly reported cause of allergic fungal sinusitis.

o Occasionally a cause of onychomycosis, ocular keratitis, sinusitis, mycetoma, pneumonia, endocarditis, cerebral abscess, and disseminated infection. Most cases are from immunocompromised patients.

• Epicoccum:

o Type I allergies (hay fever, asthma).

o No cases of infection have been reported in humans or animals.

• Nigrospora:

o Type I allergies (hay fever, asthma).

o No known toxins.

• Aspergillis/Penicillium:

o Type I allergies (hay fever, asthma) and a Type III hypersensitivity pneumonitis:

Humidifier lung, Malt worker's lung, Compost lung, Wood trimmer's disease, Straw hypersensitivity, Farmer's lung, and Oat grain hypersensitivity, o Can produce mycotoxins, however these are often found in contaminated food and are hazardous to the consumer.

o Potential pathogen for respiratory, invasive, cutaneous, ear, and corneal diseases. Severe, invasive disease is usually associated with immunosuppressed hosts. Many species grow at 37°C (body temperature).

• Smuts/Myxomycetes/Periconia/Rusts o Type I allergies (hay fever, asthma).

o No known toxins.

o Not a threat to human health.

• Pithomyces o Not Studied

4.0 CONCLUSIONS

Tehama investigated microbial levels in the air in Building 50 and compared those concentrations with outdoor, background conditions. Each sample collected represents the location sampled at that date and time. Microbial levels are constantly changing and will vary with location and time.

Microbial levels in air samples collected from Building 50 were within an intermediate and high health risk range according to OSHA recommendations. However, the background sample collected outside the building contained the highest spore count of all samples collected, and likely influenced the microbial levels inside the building. In addition, regional mold levels were at 4,304 m3, with the top three mold species being cladosporium, ascospores, and basidiospores (Children's Mercy, 2017). Mold levels outside can be directly related to mold levels inside a building. Health experts indicate that, depending on the type of mold present, the amount and degree of exposure, and the health condition of the occupant, the health effects of mold can range from being insignificant to causing allergic reactions and illness.
