The Rhode Island Democrat suggested in letters to 17 utilities that their true motive for seeking exemptions wasn’t about technology being unavailable.

Rhode Island Democratic Sen. Sheldon Whitehouse last week asked 17 utilities to hand over information about their requests for presidential exemptions from EPA’s mercury rule.

Although Whitehouse, as ranking member of the Environment and Public Works Committee, cannot compel the companies to comply, the letters could preview a line of inquiry should Democrats take the Senate and Whitehouse the gavel next year.

The exemptions issued to dozens of coal-fired power plants by President Donald Trump means “the American public is forced to pay for these exemptions and this additional risk, with their health and with their wallets,” wrote Whitehouse.
