DENVER (AP) — Hundreds of people will tell the Environmental Protection Agency what they think of proposed rules to cut pollution from power plants during public hearings Tuesday and Wednesday in Denver. The EPA is holding hearings this week in Denver, Atlanta, Pittsburgh and Washington on President Barack Obama's plan to cut carbon dioxide emissions by 30 percent by 2030, with 2005 levels as the starting point. Coal mines, electric utilities, labor unions, environmental groups, renewable energy companies, government agencies and religious and civil rights organizations are sending representatives to the Denver hearings. EPA technical experts will listen to the comments, and a transcript will go into the EPA record, agency spokeswoman Lisa McClain-Vanderpool said.
