Direct Shipment of C&D Waste from Jobsites to Landfills

King County code no longer allows C&D materials to be sent via bulk shipping containers directly from jobsites to landfills. However, in recognition of the challenges faced by the industry in immediately meeting this requirement, the Solid Waste Division is delaying enforcement of this requirement, under certain conditions, until January 1, 2018.

In order to qualify for direct disposal the following criteria must be met:

  • The project exceeds 6,000 square feet of building space that will be demolished
  • A Waste Diversion Plan, describing how materials will be recycled during demolition, is submitted to the Division by the demolition contractor acting on behalf of the property owner. The project must be planned in a manner that maximizes recovery of readily recyclable materials and adherence to disposal bans. The ability of local designated C&D material recovery facility to process mixed C&D generated during the demolition project must be considered in developing the diversion plan. Within two weeks following the Division’s receipt of the plan, the Division will either approve, require modification, or reject the plan via e-mail.
  • As part of the review process the Division may, at its sole discretion, conduct a deconstruction assessment using trained staff or consultants
  • Within 60 days following completion of demolition activities, a Waste Diversion Report, accompanied with receipts from landfill and recycling facilities where the C&D materials were disposed of, must be submitted to the Division. The report must verify where C&D was sent in compliance with the diversion plan.
    • Please submit this report and accompanying receipts to Terri Barker (if all documentation has been digitized) or:
      Terri Barker
      King County Solid Waste Division
      201 S. Jackson St., #701
      Seattle, WA 98104
  • Non-recyclable C&D sent for disposal must be shipped to one of the three Division approved landfills listed below:
    • Columbia Ridge Landfill (Arlington, OR)
    • Roosevelt Landfill (Roosevelt, WA)
    • Finley Buttes Landfill (Boardman, OR)
  • In accordance with KCC 4A.670.300 a disposal fee of $4.25 is paid to the King County Solid Waste Division for each ton of C&D directly transported to a landfill. The disposal fee will be collected by the approved landfill and paid monthly to the Division.

Additional details

Building components containing vinyl asbestos floor tile, asbestos-containing roofing materials or hazardous materials such as PCB-containing caulking compounds are inappropriate for processing to recover recyclable materials. However, portions of the structure that do not contain these materials may be appropriate for recycling. For example, when vinyl asbestos floor-tile is present only on the ground level of a building, recyclable materials above this level may be recoverable. The waste diversion plan may be supplemented by other documentation to denote areas of the building that contain asbestos or hazardous materials that could prevent recycling.

If the waste diversion plan is not followed, based on site inspections by enforcement staff, or if the demolition contractor fails to provide a Waste Diversion Report or adequate documentation, the demolition contractor and property owner may, at the discretion of the Division Director, be prohibited in the future from providing direct disposal of C&D to a landfill.

The above requirements do not apply to waste generated at C&D projects that consist of contaminated soil, friable asbestos-containing waste material or hazardous, extremely hazardous or dangerous waste (as defined under Chapter 173-303 of the Washington Administrative Code). A waste shipment record must be maintained by the generator and the disposal facility for shipments of asbestos-containing waste, and a Uniform Hazardous Waste Manifest form must accompany shipments of hazardous, extremely hazardous or dangerous waste.

Between now and January 1, 2018, the Division and industry representatives will work collectively to develop policies and procedures that ensure compliance with disposal bans at transfer stations and demolition projects that employ direct disposal of C&D waste. We are confident that this temporary measure is the most appropriate and effective manner of meeting the goals and policies of the C&D disposal program while allowing industry time to adapt and develop a workable solution.

Please contact our C&D technical staff supervisor, James Neely, should you have any questions regarding these requirements.
