Opponents of a proposed natural gas pipeline in North Florida are asking Florida regulators to reject the project, citing both dangers to the environment and a “conflict of interest” by the regulators’ boss, Gov. Rick Scott.

The Florida Department of Environmental Protection announced in July its intention to award a crucial environmental permit and rights to drill beneath riverbeds that would allow Houston-based Spectra Energy to construct the controversial, $3 billion Sabal Trail Transmission.

State records show Spectra Energy’s investors have included Scott.
