Scope of Work

We were hired by Granite School District to survey Portable 4901 at West Kearns Elementary for a pending demolition of the entire portable. Samples were taken by Jaden Ford on 8 June, 2026, and tested at Eurofins Reservoirs in Denver, Colorado. The results are included in this report.

Executive Summary

Asbestos-containing material (ACM) was not found in any bulk samples.

*- Denotes less than 1% asbestos which is regulatedby OSHA, it is recommended to review their regulations before removal

Notes

1. All materials and conditions are interpreted by Air Quality Consulting LLC

2. The Environmental Protection Agency (EPA) National Emission Standard for Hazardous Air Pollutants (NESHAP) asbestos revision as outlined in 40 CFR, Part 61, became effective November 20, 1990. The asbestos classification system outlined in the revision and included in this section is dynamic in nature. Asbestos materials classified as “Non-Regulated” at the time of the survey may become “Regulated” due to ongoing or planned maintenance, renovation or demolition actions which can transform a material containing greater than 1% asbestos from a “non-friable” and “Non-Regulated” to a “friable” and “Regulated” condition. Classification of ACM in this section and in the executive summary of this report is, therefore, based on the observations of the surveyor at the time of the survey and may or may not be appropriate at later dates.

3. Maintenance, renovation, demolition, weathering, normal wear, water or other damage can alter the “Non-Regulated” status of materials, and necessitate precautions required for handling them as “Regulated” asbestos-materials.

4. Details on testing locations, methods and results can be found on the remaining report.

Asbestos Survey and Assessment Performed at West Kearns Elementary Portable 4901

4901 S 4720 W Kearns, UT, 84118

10 June, 2026

Methods and Materials

A survey of the areas was conducted to observe, identify, locate and sample any materials suspected of containing asbestos according to NESHAP categories. All accessible areas were identified and documented.

Bulk samples were collected using approved methods and microscopically analyzed for asbestos content by a lab that participates in the National Institute for Standards and Technology’s National Voluntary Laboratory Accreditation Program (NVLAP).

Asbestos percentages were estimated utilizing the polarized light microscope (PLM) and dispersion staining methods as prescribed by NIOSH.
