Executive Summary

Industrial Hygiene Resources (IHR: www.industrialhygieneresources.com) of Boise, Idaho was contracted by HDR, Inc. to conduct a limited hazardous materials inspection of the Chapel (Facility 2606) kitchen and fellowship hall #1 located on the Mountain Home Air Force Base in Mountain Home, Idaho. The inspection was focused on asbestos containing materials (ACM) and lead-based paints (LBP). This evaluation was the first action to support renovation activities.

Rebecca Ellis and Anthony Bongiovano of IHR, conducted the inspection on September 20, 2018. Rebecca is an accredited (AHERA)1 Asbestos Building Inspector and Anthony is an EPA Lead Based Paint Inspector. Matthew Call, CIH, CSP, Vice President of IHR reviewed and approved this survey report.

Conclusions

➢ The following building materials contained greater than 1% asbestos and were characterized as asbestos containing material (ACM):

Miscellaneous:

• Black mastic under vinyl floor tile in the fellowship hall #1: ~2,300 ft2

➢ No lead-based paint was found on surfaces in the chapel kitchen and fellowship hall #1.

Recommendations

✓ Contractors should be apprised of the presence of asbestos in these buildings.

✓ Prior to any renovation requiring the removal of asbestos above the threshold of 160 square feet, or 260 linear feet, a 10-day notification must be filed with Environmental Protection Agency (EPA). All asbestos containing materials (ACM) should be abated by a qualified contractor utilizing AHERA trained workers. Upon removal, all ACM must be disposed of at a landfill qualified to accept asbestos containing waste material. All demolition projects must submit a 10-day notification to EPA even if no asbestos is present.

Background

The Chapel is located on the Mountain Home Air Force Base. This single-story building consisted of offices, restrooms, fellowship halls, a chapel, and a kitchen.

Asbestos is also regulated by the US Environmental Protection Agency (EPA) via three regulations. All regulations apply when building materials contain greater than 1% asbestos (>1%):

1) National Emission Standards for Hazardous Air Pollutants (NESHAP-Asbestos)

2) Asbestos Hazard Emergency Response Act (AHERA-schools-1983). This Act provided officials in schools, K-12, with rules and guidance for the management of asbestos containing materials. The majority of asbestos related procedures and regulations are based on this act. EPA produced regulations (40CFR763) mandating eight topics, with the first one being inspections (as produced here in this report). This section also includes EPA Worker Protection Rule (subpart G of AHERA).

3) Asbestos School Hazard Abatement Reauthorization Act (ASHARA-1992). This regulation extended AHERA regulations to cover public and commercial buildings.

The US Occupational Safety and Health Administration is charged with protecting the health of workers (OSHA: 34TUhttps://www.osha.gov/SLTC/asbestos/index.htmlU). OSHA considers building materials that contain any amount of asbestos to have the potential to cause excessive asbestos fiber exposures to employees (including contractors), and regulates operations and restoration work via its asbestos general industry and construction standards. The full standard applies when building materials contain greater than 1% asbestos (>1%).

OSHA also regulates worker exposures to lead. OSHA considers any amount of lead in paint to have the potential to cause excessive lead exposures to workers (and to their children). Where lead is present in building materials, OSHA requires employers to perform exposure assessments that consider the type of work that may disturb the lead.

Objectives

The purpose of this work was to identify Asbestos Containing Material (ACM) and Lead Based Paint (LBP) to support the planned renovation of this building. Ultimately, the purpose of this work was to protect building occupants and workers from asbestos and lead hazards.

Methods

Asbestos Inspection:

Rebecca Ellis, an accredited (AHERA)2 Asbestos Building Inspector, performed the survey work on September 20, 2018. Rebecca collected thirteen bulk samples of building materials suspected of containing asbestos during the inspection. The asbestos sampling scheme was developed to comply with ASHARA and NESHAP requirements

Asbestos containing materials (ACM) are defined as materials with an asbestos content greater than 1% by volume (>1%). If a sample is found to have a trace of asbestos, but less than 10% by PLM, it should be assumed to be asbestos. In order for a material to not be considered ACM, the sample must be re-analyzed by the point-count method, and documented to be 1% or less (≤1%). Two samples were point counted for this inspection.

Asbestos bulk samples were analyzed by DCM Science Lab, Inc. (www.dcmsciencelab.com) located at 12421 West 49th Ave, #6, Wheat Ridge, Colorado. DCM is accredited by the NVLAP/NIST3 program for asbestos in bulk materials. DCM Science Laboratory is also accredited by the AIHA4 for the analysis of asbestos air samples (www.aihaaccreditedlabs.org).

The laboratory results are presented in the Appendix.

Lead-Based Paint:

Anthony Bongiovano, an accredited EPA Certified Lead Paint Inspector, performed the survey work on the same day September 20, 2018. Anthony used a direct reading, Thermo-Scientific, Niton®, XLp 300 Lead Paint Analyzer (Serial Number 23516) to quantify concentrations of lead in paint on surfaces. These included interior walls, doors, and door jambs. Anthony sampled nine locations for lead and included periodic calibration checks for accuracy verification.

Results and Discussion:

Asbestos Containing Materials (Table III):

The Figures and Table IV document the presence and concentrations of asbestos found in building materials from this inspection. The building materials found to have regulated amounts of asbestos are as follows:

Thermal System Insulation:

➢ None.

Surfacing:

➢ None.

Miscellaneous:

Non-Regulated Materials (no regulated amounts of asbestos):

➢ The following building material samples scheduled to be impacted for renovation were found to have no regulated amounts of asbestos (<1% asbestos by volume). Any of these types of building materials generated from remodeling or demolition activities can be discarded as general construction debris at the local landfill.

✓ Ceiling tiles

✓ Sheet vinyl

✓ Cove base

✓ Mudded elbow
