The Northwest Seaport Alliance (NWSA) said that the update will give trucks a grace period of 90 days extended from the 1 January 2018 deadline, to obtain a 2007 or newer engine or equivalent retrofit, or receive a pass that allows them temporary access to international terminals.
To receive this pass, which until owners to update their trucks by no later than 31 December 2018. truck owners must demonstrate they are in the process of complying with the standard and they must complete an electronic application available from the NWSA website.
In 2008, the ports of Tacoma, Seattle and Vancouver, BC, adopted the Northwest Ports Clean Air Strategy, with a goal to have 100% of the drayage trucks serving container terminals with cleaner diesel technology – a 2007 engine with diesel particulate filter or equivalent by 1 January 2018.
To help reach the goal, the ports of Seattle and Tacoma invested more than US$15 million in matching grant funds to spur truck conversion and invest in gate infrastructure. More than 410 trucks were scrapped and replaced with new trucks through partnership with the Puget Sound Clean Air Agency and funding through DERA, CMAQ and Department of Ecology grants.
Despite these efforts, as of the end of 2017, only 53% of the roughly 4,500 trucks serving NWSA terminals met the 2007 engine or newer standard.
