The Summit Carbon Solutions pipeline proposal may have new life. The proposed pipeline would run through five states, including Nebraska and Iowa. At least one Nebraska county has denied Summit a permit, but North Dakota regulators are okaying a permit. Iowa also granted Summit a permit, but the company can't start construction until both Dakota's have approved permits. South Dakota denied a permit once, but the company plans to reapply next week. Minnesota regulators are expected to vote on a permit next month.
