In a letter to new EPA Administrator Scott Pruitt, Governor Chris Sununu complains that federal regulations on storm water runoff are too burdensome for some New Hampshire towns.
The regulations, known as MS4 permits, are meant to reduce the amount of pollutants that get discharged into bodies of water via storm water runoff from developed areas.
They would require dozens of towns in New Hampshire to make significant investments in their storm water drainage systems to comply.
New EPA Administrator Scott Pruitt said last month he favors an aggressive roll back of some EPA regulations.
