Background
The CDPHE Air Pollution Control Division’s experts provide support to comply with air pollution laws regulating asbestos-containing materials, including safe handling and disposal, certification, and permitting. Colorado Air Quality Control Commission Regulation 8, Part B sets requirements for asbestos abatement activities. The Colorado Solid and Hazardous Waste Commission's Regulations Pertaining to Solid Waste Disposal Sites and Facilities, 6 CCR 1007-2 Part 1, Section 5, sets requirements for the disposal of asbestos waste and the management of asbestos-contaminated soil.
This page has comprehensive support and guidance for managing asbestos across various sectors and industries.
Buildings of any age may contain asbestos-containing materials. If the components that will be disturbed exceed the trigger levels, they must be inspected for asbestos by a Colorado-certified Asbestos Building Inspector before starting work. An exception may be made if the building, or those portions thereof, were constructed after October 12, 1988 and if, after due diligence, the architect or project engineer responsible for the construction of the building, or a Colorado certified Asbestos Building Inspector, completes a form specified by the division that no asbestos-containing material was used as a building material in the initial construction of the building or subsequent renovations (if applicable).
- Single-Family Residential Dwellings trigger levels are:
- 50 linear feet on pipes.
- 32 square feet on other surfaces.
- Volume equivalent of a 55- gallon drum.
- Public and Commercial Buildings trigger levels are:
- 260 linear feet on pipes.
- 160 square feet on other surfaces.
- Volume equivalent of a 55-gallon drum.
- Under many circumstances, a Colorado-certified General Abatement Contractor must remove asbestos-containing material that is or may become regulated before it is disturbed by renovation or demolition activities.
A written application to the division for a notice or permit may be required, along with payment of a fee and a ten-working-day notification period (emergencies may be expedited) before the removal of regulated asbestos-containing materials can begin. All asbestos-containing material waste must be disposed of at an approved asbestos waste disposal site, regardless of the quantity or the necessity for a notice/permit.
Abatement
Asbestos abatement is the removal of friable asbestos-containing material or materials that will be rendered friable in amounts greater than the above trigger levels.
- Removal, in accordance with Regulation 8, Part B, is required if the amount of asbestos-containing material that is friable or will become friable during demolition exceeds the trigger levels.
- Abatement must be conducted by a Colorado-certified General Abatement Contractor (GAC).
- The GAC must submit an Asbestos Abatement Notification and Permit Application form to the division along with payment of a permit fee.
- A ten working-day notification period is required before the work can commence.
- The GAC must follow all other regulations (e.g. OSHA) and disposal requirements (HAZ).
Demolition
Demolition is the wrecking or taking out of any load-supporting structural member of a facility, together with any related handling operations or the intentional burning of any facility.
If you demolish, perform destructive salvage, perform de-construction, burn, destroy, dismantle, dynamite, implode, knock down, level, pull down, pulverize, raze, tear down, wreck all of a structure or any structural components, or you move a building, you are may be subject to State asbestos and Federal regulations even when there is no asbestos in the facility.
The building or area of the building to be demolished must be inspected for asbestos by a Colorado-certified asbestos inspector.
- In accordance with Regulation 8, Part B, removal is required if the amount of asbestos-containing material that is friable or will become friable during demolition exceeds the trigger levels.
- A ten working-day notification period is required before the demolition can commence.
- A Demolition Notification Application Form must be submitted to the division, even if no asbestos was found during the inspection, along with payment of a notification fee.
- Inform all contractors of asbestos-containing material in amounts less than the trigger levels or any asbestos-containing material remaining in the building.
- Follow all other regulations (e.g. OSHA) and disposal requirements (HAZ).
- Obtain local permits if required.
During demolition, the recycling of materials, such as concrete or wood, bonded or contaminated with asbestos-containing material, such as floor tile or mastic, is not permitted. Demolition of a building that has any non-friable asbestos-containing vinyl asbestos tile or tar-impregnated roofing materials in excess of trigger levels must be completed without causing the asbestos-containing materials to become friable. If possible, concrete floors covered with floor tile shall be removed in large sections. Operations such as crushing or pneumatic jacking of materials containing asbestos are not permitted. When imploding or burning a structure, all asbestos-containing material, regardless of type or quantity, must be removed before any work.
Renovation
Renovation is any alteration to one or more components in or on a facility. Examples of renovation work include replacement or repair of mechanical ventilation systems, pipes, ceilings, walls, flooring (including floor tiles), and insulating materials. Renovation may also include the construction of additions or the modification of existing components where tie-ins, joints, or other intersections may occur. For renovation activities that impact friable asbestos-containing material or asbestos-containing material that may be rendered friable, see Abatement. Removal of non-friable asbestos-containing material that will not be rendered friable by the removal activity falls under Renovation.
- Removal, in accordance with Regulation 8, Part B, is required if the amount of asbestos-containing material that is non-friable exceeds the trigger levels. Material must not be rendered friable during removal.
- Removal of friable asbestos-containing materials in excess of trigger levels must be conducted by a Colorado-certified General Abatement Contractor (GAC). Other contractors may remove non-friable materials if done in accordance with Regulation 8, Part B.
- The contractor must submit an Asbestos Abatement Notification and Permit Application form to the division along with payment of a permit fee.
- A ten working-day notification period is required before the work can commence.
- The contractor must follow all other regulations (e.g. OSHA) and disposal requirements.
Asbestos Building Inspectors
An asbestos inspection is required by a certified asbestos building inspector before any renovation or demolition work takes place, or materials need to be assumed to be an asbestos-containing material. The certified Asbestos Building Inspector must work for a registered asbestos consulting firm.

Managing asbestos in schools
In 1995, the U.S. Environmental Protection Agency granted Colorado a waiver to administer and enforce the Asbestos Hazard Emergency Response Act.. CDPHE, through Regulation 8, Part B, is designated by the governor's office to review asbestos management plans for all public and private nonprofit schools (K-12) in Colorado for compliance. If you are a school or district in need of assistance, please contact the division.

Asbestos by address
Looking for asbestos documents on a house or other type of building? Locate asbestos documents.
- Use “CDPHERM AIR Public Asbestos and Lead” search type.
- Searching using your address:
- It is most helpful to search using the numerical digits of the address with a wildcard/asterisk symbol.
- For example, an address is 123 W Broadway Ln. Use the “CDPHERM Address” box and type in the address keyword using 123*Broadway*.
- Multiple keywords can be used to narrow down the search.
- Searching is not case-sensitive.
- Use a mixture of upper and lower case.
- Use a date range so that the database can efficiently return documents of interest
- For example, locating documents for 12548 Shore Drive, Denver, CO – within a date range.
- Searching using 125* in the address keyword will result in a large amount of documents. The date range provides the documents of interest.
