This document is one in a series of fact sheets designed to assist you in becoming aware of the Missouri Department of Natural Resources’ asbestos requirements. This particular document contains general information about asbestos surveys or inspections.
Asbestos Inspection Requirements
Any regulated project subject to the National Emission Standard for Hazardous Air Pollutants (NESHAP), for Asbestos, 40 CFR Part 61, Subpart M will require an asbestos inspection. The year of construction or renovation of a regulated facility does not affect the inspection requirements. NESHAP requirements are discussed in the department’s fact sheet, Asbestos Requirements for Demolition and Renovation Projects, Fact Sheet--PUB2157. Additional asbestos information is available on the department’s asbestos website.
An asbestos inspection occurs when a Missouri certified asbestos inspector inspects a building or facility for the presence of asbestos-containing material (ACM) or suspects ACM. Suspect ACM is any material potentially containing asbestos that has not been sampled and analyzed for asbestos content. An asbestos inspection also includes re-examining a building or facility to identify the presence or location of additional or existing ACM, suspected ACM or to determine the current condition of previously identified ACM following an event, such as a fire or flood.
The following inspections or assessments do not normally qualify as thorough NESHAP asbestos inspections:
- Periodic surveillance in schools as required by the U.S. Environmental Protection Agency by the Asbestos Hazard Emergency Response Act (AHERA).
- Full AHERA inspections or reinspections in school buildings to be demolished.
- Visual inspections to determine if asbestos related work is complete.
- Compliance inspections performed by an agent of a government agency.
- Phase I environmental assessments.
Asbestos Inspection Personnel
A person certified as an asbestos inspector by the department must conduct all inspections and assessments. A list of certified asbestos inspectors is available on the department’s asbestos website.
The NESHAP requires thorough inspections be conducted. For renovation projects, inspections need only include those areas of a building impacted by the renovation work. For demolition work, thorough inspections should include destructive sampling and access to all areas of the building.
Total Number of Samples Required
No sampling is required if the certified inspector presumes that ACM is present and the owner or operator responsible for the project decides to treat it as ACM. However, for a suspect material to be considered as non-ACM, a minimum number of samples must be collected and analyzed. The department recommends inspectors follow, at a minimum, the 3-5-7 rule suggested in the Asbestos Hazard Emergency Response Act.
Inspectors should also note both the condition of the materials and their quantities in the report. If known, inspectors should comment on the potential work practice impacts on Category I and Category II nonfriable or stable ACM that have the potential to be left in-place during demolition or renovation projects.
Asbestos Sample Analysis Requirements
The department strongly recommends all asbestos analysis be conducted by either:
- A laboratory credited by the National Institute of Science and Technology through the National Voluntary Laboratory Accreditation Program.
- A laboratory with successful participation in the asbestos bulk analysis program of the American Industrial Hygiene Association.
Asbestos Inspection Report Requirements
The written report should be provided to the person requesting the inspection. The asbestos inspection and assessment report should contain the following information:
- A general description of the structure, the areas inspected (including any areas that were not accessible) and the date of the inspection.
- The location of each homogeneous material known or assumed to contain asbestos.
- If an assessment of homogeneous material is performed, the condition of each homogeneous material known or assumed to contain asbestos and is it a regulated material.
- The quantities of known or assumed ACM in square, linear or cubic feet.
- The laboratory data including the name of the lab, the results and analyst’s signature.
- The inspector’s signature and a signed and dated copy of their asbestos inspector certificate as provided by the department.
Completed copies of asbestos inspection reports should accompany all NESHAP renovation and demolition notifications submitted to the department or local agencies.
Asbestos Contact Information
For more information on the department’s asbestos requirements, you may contact the department’s Air Pollution Control Program or one of the department’s other offices:
In Missouri, there are three local agencies that have an agreement with the department to enforce Missouri’s asbestos requirements as well as local ordinances. These local agencies are:
|Kansas City||Kansas City Health Department
Air Quality Program
|St. Louis County||St. Louis County Health Department|
|St. Louis (city)||St. Louis Division of Air Pollution Control
Air Quality Program
One additional local agency does not enforce Missouri’s asbestos requirements, but may have local ordinances concerning asbestos that they enforce:
|Springfield||Springfield-Greene County Health Department of Environmental Services||417-864-1412|
Before performing a project in one of these jurisdictions, you should contact the appropriate agency to determine if any additional requirements apply.
