As Missouri communities continue to grow, older buildings are being renovated or demolished to make room for newer, more modern buildings. Properly managing waste during demolition helps prevent threats to human health and the environment.

If a demolition or renovation project is entered with an eye toward the environment and human health, the impact to both can be lessened or even removed. This will allow communities to continue to grow in harmony with the citizens and environment.

Construction and Demolition Waste Regulations
The Missouri Department of Natural Resources regulates demolition and renovation projects for institutional, commercial, public and industrial structures. The department also regulates residential structure projects such as apartment buildings with more than four units or two or more residential structures that are a part of the same project. Single family residential structures or other residential structures containing four units or less are exempt from most asbestos regulations. However, all construction, demolition and renovation wastes are regulated under the Solid Waste Management Law.

All construction, renovation and demolition waste must be properly disposed of at a permitted transfer station or landfill regardless of whether it was generated from a commercial or residential structure. Before a regulated renovation or demolition project begins, the business or entity requesting the work should make the waste disposal a part of the contract. This will deflect liability if the waste is not properly managed and should be considered by the contractors during the bid process. Demolition or renovation operations can create several different kinds of waste:

For more information about proper hazardous waste disposal contact the department’s Hazardous Waste Program at 573-751-3176.

Asbestos
Asbestos is a naturally occurring mineral fiber. It can be positively identified only with a special type of microscope. Because the fibers are so small, they can float into the air, where they can be inhaled and accumulate in the lungs. This can lead to diseases like asbestosis, mesothelioma and lung cancer.

Most products made today do not contain asbestos. However, until the 1970s, asbestos was added to a variety of products to strengthen them and to provide heat insulation and fire resistance.

For more information about the proper disposal of asbestos containing materials, contact the department’s Air Pollution Control Program at 573-751-4817 or see the fact sheet Asbestos: What is it and why is it a concern?, PUB2077, available on the department’s website at www.dnr.mo.gov/pubs/pub2077.pdf.

Asbestos Inspection Requirements
Additionally, before a regulated project begins, a state certified asbestos inspector must inspect the entire structure for asbestos containing material. If the inspector finds regulated quantities of asbestos containing material or assumes it to be in the structure, an asbestos abatement contractor must complete the project.

Abatement contractors are trained in the proper procedures for safely removing and disposing of asbestos containing material. The Department of Natural Resources has a listing of Missouri-certified asbestos professionals and training providers on the department’s website at www.dnr.mo.gov/env/apcp/Asbestos.htm. ¬†

The department requires notification for all regulated demolition and asbestos abatement projects. The information must be submitted to the department’s Air Pollution Control Program at least 10 working days before the project begins. Review Asbestos Requirements for Demolition and Renovation Projects, PUB2157 at www.dnr.mo.gov/pubs/pub2157.pdf for more information regarding these requirements.

Open Burning of Construction or Demolition Waste
It is important to note there are limited circumstances where waste from a renovation or demolition project may be open burned in Missouri. Untreated wood waste in limited circumstances may be open burned with a permit from the Department of Natural Resources. The burning of waste can lead to toxic emissions like dioxins, volatile organic compounds and hydrogen chloride. Those nearby the burn site could potentially experience skin and eye irritation, respiratory problems, and even central nervous system issues like headaches or dizziness.

For more information about open burning, contact the department’s Air Pollution Control Program at 573-751-4817 see the fact sheet Facts on Open Burning under Missouri’s Regulations, PUB2047 available at www.dnr.mo.gov/pubs/pub2047.pdf.

Local Ordinances
There may be local ordinances stricter than the state’s rules and regulations. Any business or entity beginning a renovation or demolition project should be aware of all of the ordinances and regulations affecting them before the project starts.
