Ecology is asking for comments about a revised proposal for reducing nitrogen oxide emissions from TransAlta’s coal-fired power plant near Centralia in Lewis County.
The TransAlta plant is the state’s largest stationary source of nitrogen oxide emissions. Nitrogen oxide is a visibility-reducing pollutant, which contributes to regional haze in national parks and wilderness areas. The U.S. Environmental Protection Agency (EPA) has directed states to reduce regional haze in coming decades.
Speaking of TransAlta, the Canada-based multinational company has opened its new U.S. headquarters in Olympia. Here’s the company’s news release, as well as a statement from Gov. Chris Gregoire.
Here are a few other news items related to emission reductions:
- The Seattle Times recently detailed a proposal to use liquefied natural gas to power some state ferries, instead of diesel fuels. The story, and the idea, focus more on long-term fuel cost savings, but it also notes that the fuel switch would reduce the vessels’ carbon dioxide emissions.
- The Bellingham Herald reports that the Whatcom Transit Authority has received grant money to buy five hybrid buses. Doing so will save fuel costs and cut emissions.
- And the Los Angeles Times reported last week that environmental groups are suing three companies that operate 17 rail yards throughout California because of the toxic diesel particles being emitted by locomotives and trucks over surrounding communities.
