City/Region

Pitkin County, CO

Link: https://pitkincounty.com/DocumentCenter/View/26097/Ord0152020

Description

A 2016 analysis of C&D loads sent to the landfill determined that 35% of those materials could have been diverted through existing recycling and reuse programs in Pitkin County. To extend the life of the landfill, the County has taken on new efforts to encourage diversion of C&D materials through the passage of Ordinance No. 015-2020 (and Amended Ordinance No. 008-2023). C&D waste diversion requirements are now tied to building and demolition permits from the Pitkin County Community Development Department and we have implemented new tipping fees for disposal of C&D materials.

A tracking system monitors load amounts and notifies customers when they reach the tier limits. Once a tier limit has been reached, the scale system will then charge at the next higher tier tipping fee. The purpose of a tiered pricing structure is to encourage diversion and include construction projects outside of unincorporated Pitkin County.

https://pitkincounty.com/192/Building

https://www.landfillrules.com/construction-and-demolition-debris

Scope All construction and demolition waste disposed of at County landfill.
Incentives for compliance

Source-separated loads of recoverable materials (i.e. loads containing only one type of material) brought to the SWC do not count towards the tiered tonnage limits and are cheaper to dispose of than in mixed loads.

Penalties for non-compliance

 The SWC uses a tiered pricing structure to apply to all construction and demolition waste disposed of at our landfill. The pricing is determined on a per-job tonnage basis and applies to all C&D loads from permitted jobs within and outside of Pitkin County. Disposal rates from each job are tracked and assessed a higher tipping fee at designated tonnage limits.

Loads containing a combination of trash and any of the recoverable materials listed below will be charged the maximum tipping fee (Tier 4).

City/Region

Metro, a regional government serving the three most urban counties in Oregon (Washington, Clackamas and Multnomah).

Description

Metro established requirements for processing mixed dry waste and established recovery performance targets and reporting for three materials in this waste stream (wood, metal, cardboard) through the Enhanced Dry Waste Recovery Program (EDWRP) in 2007, with the program requirements becoming active in 2009.

Under EDWRP, mixed dry waste must be processed at a material recovery facility before being disposed. As initially adopted, a facility that performs material recovery cannot have more than 15 percent, by total combined weight, of wood, metal, and cardboard of a certain size in its processing residual. A facility must demonstrate that it meets the recovery performance standard by completing quarterly sampling of its processing residual and reporting the results to Metro.

In 2024, Metro suspended certain recovery, sampling and reporting requirements as historical evidence, current market conditions, and observations from inspections indicated that those requirements were no longer necessary because facilities have equipment, procedures, and markets in place to adequately meet the applicable recovery requirements.

Scope

The majority of policy direction that created EDWRP is in Metro Code Chapter 5.01 under 5.01.260 Obligations and Limits for Selected Types of Activities. However, Metro Code does not identify which provisions are currently suspended. A history of the suspensions of the EDWRP program provisions is available on Metro’s website for Rules, Guidance and Procedures

Incentives for compliance

The incentive is for a facility to remain in compliance with Metro’s requirements. Facilities that are not compliant with EDWRP are in violation of their Metro authorization.

Penalties for non-compliance

Metro may pursue financial penalties for non-compliance or impose other requirements to bring a facility into compliance.
