After several years of collaboration among government agencies and Portland Metro, the City of Portland adopted the
Clean Air Construction contracting standard in 2018. The initiative reduces diesel emissions related to government-funded construction projects. Since then, Multnomah and Washington Counties and Portland Metro have each adopted identical standards and DEQ continues to offer technical assistance during implementation.
As part of HB 2007 (ORS 279C.537), the legislature directed DEQ to create a model Clean Diesel Contracting standard for state contracting agencies to assist with the development of their own rulemaking process. DEQ is currently drafting the model standard and expects to present it to contracting agencies in 2021.
