PORTLAND, Maine (AP) — Former Maine independent gubernatorial candidate Eliot Cutler is joining a coalition that’s pressing Maine Sens. Olympia Snowe and Susan Collins to protect the Clean Air Act.

The coalition comprised of health professionals, public officials and citizens is critical of a proposal by West Virginia Sen. Jay Rockefeller to delay for two years Environmental Protection Agency regulation of greenhouse gases, as well as another effort to delay the EPA’s plan to revisit ground-level ozone standards.

Cutler, a lawyer, helped craft the 1970 Clean Air Act while working for Sen. Edmund Muskie of Maine.

He said during a rally Tuesday in Portland that “it’s critical that Snowe and Collins continue Maine’s legacy of commitment to public health by voting against these dangerous proposals.”
