Asbestos Disposal Denver: CDPHE Rules Guide
Asbestos disposal in Denver, Colorado is governed by strict environmental safety regulations enforced by the Colorado Department of Public Health and Environment (CDPHE) under Air Quality Control Commission Regulation No. 8, Part B. Across the Denver metropolitan area and surrounding Front Range communities, disposing of hazardous mineral waste requires certified packaging, state waste manifests, and authorized landfill destinations.
The Colorado CDPHE Regulatory Framework for Asbestos Waste
In Colorado, the management and disposal of asbestos-containing waste material (ACWM) is administered by the Hazardous Materials and Waste Management Division and the Air Pollution Control Division of the CDPHE. Under Regulation No. 8, Part B, any renovation, demolition, or spill cleanup generating regulated asbestos debris must comply with rigorous containment and transportation standards.
Unlike standard municipal trash, asbestos cannot be discarded in curbside dumpsters or mixed with general construction debris. In Denver and surrounding counties (Adams, Arapahoe, Douglas, and Jefferson), transport vehicles carrying commercial quantities of asbestos must be licensed, placarded according to Department of Transportation (DOT) Class 9 hazardous materials codes, and accompanied by a completed Colorado Asbestos Waste Shipment Record (WSR).
| Regulatory Authority | Governing Code | Jurisdictional Authority in Denver | Key Enforcement Mandate |
|---|---|---|---|
| CDPHE Air Pollution Control | Regulation No. 8, Part B | Demolition notifications, packaging, zero emissions | 30-day advance notice for commercial projects |
| CDPHE Waste Management | 6 CCR 1007-2 (Solid Waste) | Permitted landfill operations, waste manifest audits | Mandatory 6-inch daily soil cover enforcement |
| Denver Dept of Public Health | Denver Revised Municipal Code | City and County of Denver environmental oversight | Local dust suppression and demolition permits |
| US DOT (Federal Region 8) | 49 CFR § 173.216 | Commercial transportation on Colorado highways | Class 9 hazardous material placarding |
Packaging and Labeling Standards for Denver Waste
To eliminate the risk of fiber aerosolization during transport and disposal, CDPHE regulations mandate that all asbestos waste must be adequately wetted with amended water throughout collection and packaging. Waste must be sealed inside two independent layers of heavy-duty, leak-tight polyethylene bags, with each bag having a minimum thickness of 6-mil (0.006 inches).
For sharp debris—such as broken metal lath, fractured transite cement boards, or jagged pipe sections—contractors must utilize puncture-resistant fiberboard drums or heavy plastic containers lined with 6-mil poly. Every bag and container must feature permanent, pre-printed OSHA warning labels, accompanied by the name and physical site address of the waste generator.
| Waste Packaging Type | Material Standard | Permitted Waste Material | Required Sealing Method |
|---|---|---|---|
| Double 6-Mil Poly Bags | Heavy polyethylene, pre-printed labels | Scraped popcorn ceiling, floor tiles, pipe wrap | Twisted gooseneck seal with heavy duct tape |
| Rigid Fiberboard Drums | Heavy kraft cardboard, steel locking ring | Sharp debris, metal lath, structural plaster | Airtight clamping ring lid with rubber gasket |
| Palletized Poly Bundles | Double 6-mil poly envelope wrapping | Intact transite siding shingles, exterior panels | Continuous perimeter taping, banded to wood pallets |
| Sealed Roll-Off Containers | Double 6-mil poly accordion liner | Bulk structural commercial demolition debris | Hermetically taped top flap enclosure |
Authorized Landfills in the Denver Metropolitan Area
Only specifically permitted solid waste facilities in Colorado are legally authorized by CDPHE to accept asbestos-containing waste material. Not all municipal transfer stations or landfills have dedicated asbestos disposal cells. In the Denver metro area, authorized disposal sites include the Denver Arapahoe Disposal Site (DADS) in Aurora and the Foothills Landfill in Golden.
Upon arrival at an authorized landfill, waste haulers must present the completed Waste Shipment Record (WSR). Landfill equipment operators place the wrapped waste gently into active asbestos disposal trenches, avoiding mechanical crushing. Within 24 hours of placement, the waste must be covered with at least six inches of compacted non-asbestos clean soil or an approved synthetic daily cover to prevent windblown dispersion.
How to Properly Package and Dispose of Asbestos Waste in Denver
Saturate Waste with Amended Water
Spray all asbestos-containing debris thoroughly with water mixed with liquid surfactant to ensure it remains damp throughout bagging.
Pack in Primary 6-Mil Warning Bag
Carefully place wet waste into a certified 6-mil poly bag, squeeze out excess air, twist the neck, and tape it into a gooseneck seal.
Decontaminate and Double-Bag
Wipe down the exterior of the first bag inside the decontamination wash room, place it inside a second clean 6-mil bag, and seal identically.
