The initial group of meetings, which are open to the public, began on October 1 and includes Atlanta, Denver, San Francisco, Dallas and several other large cities.

The EPA said the Boston hearing is now set for November 4 from 10am to 3pm at the US EPA New England Memorial Hall.

Additionally, the Philadelphia event will be held November 8 from 10am to 4pm at US EPA Region 3 at the city’s William J Green Jr Federal Building.

According to the EPA, power plants are the nation’s largest stationary source of carbon pollution, responsible for about one-third of all greenhouse gas pollution in the US.

“The feedback from these 11 public listening sessions will play an important role in helping EPA develop smart, cost-effective guidelines that reflect the latest and best information available,” officials said in its first announcement of the gatherings.

“The agency will seek additional public input during the notice and comment period once it issues a proposal by June 2014.”
