Frequently asked questions
The Oregon Department of Environmental Quality requires Metro to screen for, and prevent the acceptance of, asbestos in materials brought to Metro Central and Metro South transfer stations. To ensure the safety of our customers and the public, Metro requires paperwork for all loads of construction, remodeling or demolition waste for materials that may contain asbestos.
Loads of construction, remodeling and demolition debris brought to Metro transfer stations will be thoroughly screened for materials that may contain asbestos. Here are some steps you can take to prepare your load of construction waste for delivery to a Metro transfer station:
- Use an accredited asbestos inspector to survey your project for materials that may contain asbestos.
- Have any suspect materials tested by an analytical laboratory.
- Fill out a Construction and Demolition Waste Acceptance form (which you can download from the link below).
- Bring test results with your load to a Metro transfer station to show it contains 1 percent or less asbestos by weight.
Analytical test results certifying all tested sample results contain 1 percent or less asbestos by weight are required for the following items:
- Ceilings and walls: acoustical tiles, glue dots, plaster, and spray-on and "popcorn" texture
- Flooring: vinyl tiles (9” x 9” and 12” x 12”) and sheet vinyl
- Insulation/fireproofing: Spray-applied, vermiculite, monokote, thermal system insulation (TSI) e.g. Aircell, Magnesia or Mag (fiberglass, cellulose and mineral wool exempt from testing requirement)
- Exterior walls: cement siding shingles (Transite/CAB)
- Heating: White TSI paper that is complete wrap or seam tape on ducting, air-duct cement and insulation
- Fire doors, fire/kiln brick and fireproofing
Starting April 1, 2017, Metro will require similar test results for asbestos for the following list of construction materials, in addition to those listed above:
- Surfacing materials for interior wall and ceiling systems: textured surfacing material that covers the entire surface of the wall and/or ceiling system such as trowel-applied, skim or brown coats, and orange peel texture
- Insulation: block, boiler and spray-applied sink undercoating
- Gaskets: furnace, mechanical (not automotive), boiler, and wood stove
- Roofing materials: tar paper, felt, silver/white roofing paint, Nicolite paper (white paper used under cedar shingles and parapet metal siding)
- Various compounds: window glazing, adhesives, caulks, patching, mastics and vapor barrier products (plastic or polyethylene synthetic materials such as “Tyvek” are exempt from testing)
- Electrical: switch gear, circuit boxes and fuse panels from industrial applications and some residential applications; wiring with cloth insulation (Wiring commonly referred to as Romex is exempt.)
Metro reserves the right to request analytical test results for other materials not listed above.
New materials manufactured from 2004 on: Unused materials listed here that were manufactured in or after 2004, or similar used materials coming from new construction built in or after 2004, do not need to be tested for asbestos.
Please note: Flat/built-up roofing is not accepted, even if customers present negative analytical test results.
Customers who bring these materials to Metro Central or Metro South transfer stations must certify that their loads of construction, remodeling and demolition debris are asbestos-free. To do this, complete a Construction and Demolition Waste Acceptance form.
Documentation must be presented to the bay spotter for review prior to opening the drop‐box or truck doors. The load will be inspected by the spotter to make sure it matches the description of materials on the Construction and Demolition Waste Acceptance form. Metro will retain a copy of the acceptance form and test results for its records. Customers who do not comply with the procedures may be charged testing and clean-up fees.
Where to take waste that contains asbestos
Residential (non-commercial) customers may bring limited amounts of asbestos-containing materials to a Metro household hazardous waste facility. The materials must be delivered in no more than two sealed 25-pound double-lined six-millimeter plastic bags. The asbestos-containing materials must be bagged and sealed before they arrive at a Metro household hazardous waste facility. Metro accepts no more than two 25-pound bags per customer per day.
Commercial customers and residential customers with more than 50 pounds of asbestos-containing materials can take their load to Hillsboro Landfill. It is the only landfill near the Portland metropolitan area that can receive waste that contains asbestos for disposal. Loads must be properly and safely prepared before they are delivered to the landfill. Please call the landfill in advance of your delivery. For details, hours of operation and pricing, call Hillsboro Landfill at 503-640-9427.
