Boulder County Commissioners on Tuesday continued their fight against oil and gas firms tapping distant minerals from multi-pad drilling sites by filing two lawsuits naming drilling companies — Crestone Peak Resources and 8 North — as defendants. The county is suing Crestone Peak Resources over its plans to drill 140 wells that would drain 10 square miles on three multi-well pads along Colo. 52 north of Erie. It is suing 8 North — which it has already named in a separate lawsuit filed last month — over a proposal to drill 32 wells on two pads along East County Line Road that would drain 2,720 acres in Boulder County. That site is the focus of both county suits naming the company.
