The House passed the Jordan Lake rules bill on Thursday night and the Senate approved it early Friday on a 28-13 vote, sending it to the governor.
The bill leaves in place current rules governing environmental protections at Jordan Lake, and delays for three years rules that have not yet been adopted. The state will pay for a water clean-up demonstration project involving mechanical devices.
Molly Diggins, state director of the Sierra Club in North Carolina, issued a statement after the final approval saying the three-year delay will pollute the lake further.
"We have a plan in place to clean up Jordan Lake," Diggins said. "But now lawmakers in Raleigh have needlessly delayed that plan."
She said the pilot project, at a cost of nearly $2 million, will not stop pollution from flowing into the lake, which provides drinking water for more than 300,000 people in the Triangle.
