Missouri's Asbestos Requirements for Demolition and Renovation Projects

In 2017, the Missouri Department of Natural Resources published essential guidelines for the testing and remediation of asbestos in construction.

PUB2157 is titled “Asbestos Requirements for Demolition and Renovation Projects” and produced by the DNR’s Division of Environmental Quality. It contains vital information regarding how to determine if your demolition or renovation project is regulated by the department’s air pollution control requirements. It also explains the basic requirements for asbestos inspection and abatement, notification of regulated demolition and renovation projects, and requirements for disposing of asbestos waste.

Here are some important highlights of these guidelines:

The Missouri Department of Natural Resources (DNR) regulates the removal and disposal of asbestos-containing materials (ACM) in demolition and renovation projects involving institutional, commercial, public, industrial, or residential structures, installations, or buildings. The only exception is a single residential structure with four or fewer dwelling units.

Before demolition or renovation activities, regulated structures or those areas that will be subject to demolition or renovation activities must be thoroughly inspected by a Missouri-certified asbestos inspector to determine if any asbestos-containing materials are present. The inspector should identify all potential asbestos-containing (suspect) materials that may be disturbed by the demolition or renovation activity. Samples of the suspect materials should be collected and submitted for laboratory analysis to determine if they contain asbestos. The inspector should generate a report of their findings from the inspection. The information should identify all suspect materials and indicate the amount, location, category, and condition of the suspect materials. The report should also include a copy of the analytical results and chain of custody for all samples collected.

If the asbestos inspection determines 160 square feet, 260 linear feet, 35 cubic feet (threshold quantities), or more of regulated asbestos-containing material will be impacted by demolition or renovation activities, a Missouri-registered asbestos abatement contractor must remove all of the material. Abatement contractors are trained in the proper procedures for safely removing and disposing of asbestos-containing material and may only employ workers trained and, subsequently, certified by the department to participate in a regulated project.

Asbestos waste from regulated projects involving threshold quantities of regulated asbestos-containing material must be handled in strict accordance with the department’s requirements for asbestos waste disposal. Wastes from these projects must be transferred to an approved sanitary landfill or transfer station by registered asbestos abatement contractors, who are trained in the provisions for proper waste disposal.

The State of Missouri recognizes that asbestos is a dangerous material that warrants regulation in its inspection, mediation, removal, and disposal.
