LIMITED ASBESTOS SURVEY; IN SUPPORT OF A CCTV SYSTEM PROJECT; BUD

DAY CENTER; BUILDING 1256; FAIRCHILD AFB, WA

1.0 INTRODUCTION

The 92nd CML Engineering Squadron of Fairchild AFB, contracted Mountain Consulting Services, (Mountain Consulting) to conduct a limited asbestos containing materials survey for the suspect interior building materials present throughout the Bud Day Center in Building 1256, located on

Fairchild AFB, Washington. The survey was conducted to facilitate a CCTV systems replacement project.

Mr. Ryan Yocom; EPA-accredited AHERA building inspector, certification: BIR-20170915-06, expiration: 9/15/18, conducted a limited field survey of the identified building area/materials on

September 14thof 2017. [Refer to Appendix A for inspector certifications & laboratory accreditations].

SITE DESCRIPTION

Building 1256 is a newer single-story masonry & steel constructed offices/survival school educations structure, built on a concrete slab foundation. The building is located within the newer survival school buildings complex portion of Fairchild AFB on the southern half of the base accessed from Thorpe Road and Survival Loop.

For this survey only the suspect interior drywall, joint compound and ceiling tiles materials from the

Bud Day Center wing of the building interior were targeted to be tested for asbestos content to facilitate a scheduled CCTV System project. The suspect materials to be impacted for this project were identified by the 92nd CML Engineering Squadron representative.

Fairchild AFB is located west of the City of Airway Heights, Washington in Spokane County. The

Air Force Base is bordered by Highway 2 to the north, Rambo Road to the east, Medical Lake Road to the south, and Graham Road to the west.

2.0 SCOPE OF WORK

ASBESTOS MATERIALS SURVEY: The scope for limited asbestos survey work was designed to meet the requirements for asbestos inspection and due diligence notification in the Occupational Safety and Health Administration (OSHA) Asbestos Standard (29 CFR 1926.1101), the National Emission

Standards for Hazardous Air Pollutants (NESHAP; 40 CFR 61), and applicable portions of the

Asbestos Hazardous Emergency Response Act (AHERA) and regulations in 40 CFR 763.

FA4620-18-Q-A025

October 3, 2017 PAGE 2 Mountain Consulting Services, LLC

This survey was conducted through visual evaluation, classification and analysis of suspected

ACM’s used in the construction or remodeling of the surveyed area/select materials within the identified structure. The survey included the following tasks:

Visual survey and assessment of the location and condition of suspected materials.

Collection and analysis of bulk samples from suspected ACM materials.

Preparation of a report summarizing the identification and assessment of any ACM materials.

3.0 ASSESSMENT SURVEY PARAMETERS

3.1 HOMOGENEOUS MATERIALS

Homogeneous materials are those considered to be consistent throughout an area based on color, texture, and construction era. For the purpose of this survey, homogeneous areas were delineated using the construction era, material composition, and material location as the primary considerations.

Material appearance, texture, size, color, and analytical results may support assumptions about each material’s homogeneity.

3.2 BULK SAMPLING

Suspected ACMs were collected according to guidelines in 40 CFR 763.85 and were sampled to determine the type and percentage of asbestos by volume. At least Two (2) Samples were collected from each selected miscellaneous material type; at least Three (3) Samples from each thermal system insulation (TSI) materials; and suspect surfacing materials were sampled according to the AHERA

“3/5/7 rule” for spray or trowel applied materials.

For other types of suspect materials, or materials assumed to be non-ACM, regulations require the on-site AHERA building inspector to determine the appropriate number of samples. The quantity of material present, manufacturer’s labels, appearance, construction or renovation era, and inspector’s expertise were used to determine the number of samples.

A homogeneous material is considered to be a Regulated ACM if one or more sample results produce greater than 1% asbestos. The EPA recommends that at least three samples be analyzed by polarized-light microscopy (PLM) for the following types of materials in order to prevent false negative results (less then <1% asbestos):

Materials that contain low concentrations of asbestos fibers (less than 10%);

Materials with asbestos fibers tightly bound in a matrix;

Materials with milled asbestos fibers (fine fibers);

Materials with hand-mixed asbestos fibers; and

Materials with a combination of these characteristics.

FA4620-18-Q-A025

October 3, 2017 PAGE 3 Mountain Consulting Services, LLC

All bulk samples must have results below 1% asbestos before the material may be classified in accordance with AHERA rule as not being Regulated ACM. If asbestos is detected in the material at less than <1%, WISHA worker health and safety due diligence regulations still apply.

3.3 LABORATORY AND ANALYTICAL METHODS

Mountain Consulting submitted for analysis Ten (10) bulk asbestos material samples collected from

Five (5) different homogeneous suspect building materials targeted for testing. During laboratory analysis, three (3) bulk samples were sub-divided, and one sample was not analyzed resulting in a total of thirteen (13) samples analyzed for this project.

The samples were submitted for analysis to Mountain Laboratories of Spokane Valley, Washington using proper chain of custody procedures. Mountain Laboratories participates in the national voluntary laboratory accreditation program (NAVLAP) and is a NAVLAP accredited asbestos testing laboratory, NAVLAP code: 101890-0. Laboratory accreditation certificates are provided in

Appendix A.

4.0 RESULTS

This section describes suspect materials that were found to be asbestos containing (Regulated ACM) or proven to be free of asbestos minerals (ACM-Free). [Refer to the bulk sample analysis report in

Appendix B for specific sample composition and the site drawing in Appendix C for sampling locations].

4.1 MATERIAL CONTAINING 1% OR MORE ASBESTOS

ACMs are materials proven to contain at least 1% asbestos or greater. AHERA and NESHAP regulations distinguish between friable and non-friable forms of ACM. A friable material is defined as one that can be “crumbled, pulverized, or reduced to powder by hand pressure when dry.”

Friability is an indication of a material’s ability to release asbestos fibers into the air. Regulated

ACMs are defined by NESHAP as all friable ACM and non-friable ACM that may be disturbed by renovation or demolition.

All samples suspect building materials included for asbestos content testing for this project were proven to be ACM-Free. Refer to Section 4.4 for a list of materials tested.

4.2 MATERIALS ASSUMED TO CONTAIN ASBESTOS

No suspect materials were assumed to contain asbestos during this survey activity.

FA4620-18-Q-A025

October 3, 2017 PAGE 4 Mountain Consulting Services, LLC

4.3 MATERIALS WITH ASBESTOS CONCENTRATIONS OF LESS THAN <1%

No analyzed materials were proven to contain less than 1 percent (<1%) asbestos during this survey activity.

4.4 NON-ACM MATERIALS

Microscopic examination of samples collected from the following suspect building materials in support of the CCTV System project for Building 1256, did not detect the presence of asbestos minerals (ACM-Free):

White / Light Gray Acoustic Ceiling Tiles Throughout Building (samples 1 & 2)

Gypsum Wallboard Paneling (sheetrock in Room 141 & 130B) (samples 3 & 4)

Joint & Taping Compound (associated with tested S/R) (sub-samples 4A)

Gypsum Wallboard Paneling (sheetrock in Room 136 & 137) (samples 5 & 6)

Joint & Taping Compound (associated with tested S/R) (sub-samples 5A & 6A)

Gypsum Wallboard Paneling (sheetrock in Room 142E) (samples 7 & 8)

Gypsum Wallboard Paneling (sheetrock in Rooms 138 & 139) (samples 9 & 10)

5.0 CONCLUSIONS AND RECOMMENDATIONS

Our findings are based strictly on information obtained from our site observations and from sample analysis during survey activities. Consistent with our knowledge and understanding of environmental regulations, particularly as they apply to the potential liabilities associated with asbestos-containing building materials, we present the following conclusions and recommendations.

5.1 CONCLUSIONS

The tested and analyzed building materials proven to be free of asbestos require no further action in regards to asbestos regulations. These materials may be impacted without any specialized personnel training and disposed of in a landfill that accepts standard construction debris.

5.2 RECOMMENDATIONS

If any materials not identified in this survey are uncovered during renovation or demolition, they must be assumed to contain asbestos until sampling and analysis prove otherwise. ACM must be handled in accordance with OSHA, NESHAP, and local regulations.

The Spokane Regional Clean Air Agency (SRCAA), the local building department and the local fire department should be contacted regarding possible permit requirements.
