Norfolk said the paperwork for the suit is almost ready, and he expects to present it to a judge sometime in July.
Baker said he has no financial stake in closure of Adirondack lakes to float plane access.
"I once owned three seaplanes," Baker said. "I don't own any now, so I have no personal interest in making money off of it.
"My interest is for seaplane access to these 40 lakes for the disabled. And I'm sorry if the Adirondack Mountain Club and the Audubon Society, the Sierra Club, Friends of the Animals and Earth First - if they don't like it, let them explain it to a judge, not me."
Baker is currently running for Warrensburg Town Supervisor. DEC officials had no comment on the proposed lawsuit. A spokesman for the Adirondack Park Agency did not return a call for comment.
