Construction crews at the Con-way site in Northwest Portland will install “clean diesel” technology to minimize toxic air emissions in the area.

C.E. John Co., a Vancouver developer that is building a two-acre housing project at Northwest 21st Avenue and Raleigh Street, negotiated a deal with the neighborhood association to use exhaust controls on cranes, trucks and earthmovers. The controls, costing about $17,000 per engine, will eliminate up to 90 percent of the pollution from the construction equipment.

John will pay for the upgrades with a $132,000 grant awarded by the Oregon Department of Environmental Quality.

“To my knowledge, this is the first company in the Northwest to voluntarily agree to use clean diesel construction equipment for a private construction project,” says Kevin Downing, DEQ air quality planner.

DEQ used money provided by the federal Congestion Mitigation and Air Quality Improvement Program.

DEQ’s Portland Air Toxics Solutions study identified construction diesel equipment as one of the five leading sources of air toxics in the region.

John is the master developer for the Con-Way Master Plan, and agreed to use clean diesel equipment where possible as the site redevelops over the next decade or so. The housing project is the first redevelopment of the site.
