I strongly support the conversion of the TransAlta coal plant to natural gas. Our state has come out against cheap and efficient fuels for households, such as natural gas, but if the electric generating plant could be converted from coal to natural g...↓

Reliable access to electricity is an expectation of the general public. As we transition from fossil fuels to a cleaner and more sustainable option, it is vital that we more forward in a manner that encourages this transition but recognizes that we ...↓

I fully support TransAlta's coal-to-gas conversion at the Centralia plant. Nat gas is far superior to natural gas for baseload and peaking power. It is abundant, domestically sourced, and delivers far higher energy density per unit, which means lower...↓

I support TransAlta's conversion to natural gas. Knowing Centralia's need for electricity, jobs, and the community's desire for appropriate natural conservation, the conversion to natural gas is a good intermediate step away from coal. Ultimately, co...↓

I believe we should permit the unit 2 power plant at Centralia to convert to Natural Gas fuel. As a govermental affairs employee of IBEW 77 for many years I advocated for the conversion to Natural Gas.

We have a need for the electrons to be provide...↓

It is unbelievable that WA, of all places, that aspires to a leader in green energy would give any consideration to building a new fossil fuel plant. But this is not just wanting to "be green".
It seems to me some one is not doing their homework. ...↓

I'm deeply disappointed to see our own Department of Ecology undercut the Clean Energy Transformation Act and use a conversion to keep this plant running for two more decades — sidestepping the coal phase-out SB 5769 mandated.

This deal locks Washin...↓

This project will further degrade air quality and add airborn and other industrial polution to fragile river environments an populated areas. STOP IT!

No no no no. We should not be moving from one fossil fuel to another. No to gas. Our planet is on fire. We must slow down climate change spark by spark. No to fast tracking your review of this project. Look at this carefully. Realize that we cannot a...↓

Washington has positioned itself as a global climate leader, but approving this expensive and dirty project as-is would move our state in the wrong direction. TransAlta is deliberately misleading the public and state regulators must commit to a robus...↓

Converting from coal to gas, another fossil fuel, makes no sense. Burning fossil fuels of any kind spews poisonous gases into the atmosphere, destroying our beautiful planet for generations to come. Please, install a clean battery system like Califor...↓

Comments re: TransAlta proposal
Converting two coal-fired power plants at the TransAlta facility to natural gas is foolish. First, let's be clear: Natural gas is a euphemism that's meant to pretty-up what's going on.
The gas in question in this inst...↓

Conversion of existing coal burning boiler to natural gas is an acceptable move forward for the facility. Natural gas is a cleaner burning product than coal and should have been done many years ago. All conversions to natural gas are highly recommend...↓

A short comment. The plan put in place to convert the TransAlta mine is a good one. No need to modify and don´t bow down to the federal administration.
