TACOMA, Wash. — The Puget Sound Clean Air Agency will hire a consultant to do an additional review on greenhouse-gas emissions related to a proposed liquefied natural gas plant in Tacoma.

The News Tribune reports the agency announced the plan to do a supplemental environmental impact statement Wednesday.

The study would need to be finished before builder Puget Sound Energy could get a required air permit for the project.

Results of the study also could potentially change the outcome of the permit application.

Clean air agency compliance director Steve Van Slyke says they’re looking for a quantitative analysis of the greenhouse-gas emission effect downstream of the plant and upstream of the plant.

Protesters, including the Puyallup Tribe, are calling for a halt to construction citing environmental concerns.

Puget Sound Energy spokesman Grant Ringel says the company is disappointed by the delay but confident it will clear the additional hurdles.
