Another company, US Development, is looking at the port's Terminal 3 to load oil from trains onto ships.
Both proposals have drawn opposition from citizen groups that were formed to oppose a coal export terminal. Friends of Grays Harbor and Citizens for a Clean Harbor are concerned about the risk of spills and the impact of train traffic.
The Port of Tacoma also has received proposals for a bulk liquids handling facility on the former Kaiser aluminum smelter site on Blair Waterway.
Port spokeswoman Tara Mattina told The News Tribune she could not discuss proposals because of ongoing negotiations.
The new oil fields are affecting the Northwest in other ways. The biggest beneficiary is Burlington Northern Santa Fe, which owns most of the rail lines across the northern United States between Puget Sound and Chicago.
The Port of Olympia has found new business importing oil field supplies, including special sand used in the hydraulic fracturing drilling process. The Bradken foundry in Tacoma is expanding to make large metal castings used in the energy industry.
