Proposed ND oil rules will cut waste pit numbersRegulators say proposed new rules for North Dakota's oil country will reduce the number of waste pits.
BISMARCK, N.D. (AP) — Regulators say proposed new rules for North Dakota's oil country will reduce the number of waste pits.
State Department of Mineral Resources director Lynn Helms says each North Dakota oil well now has a pit for dumping liquid waste and rock chips from drilling.
More than 2,000 pits were built this year.
The new rules will ban liquid waste dumping for most of North Dakota's newly drilled wells. Oil producers will be able to use pits only to dispose of rock chips.
Helms says the changes will cut down on the time it takes to reclaim the pits. He says it should help relieve the problem of birds landing in the pits.
Helms says the rules should cut the number of waste pits down to 100 or 200 each year.
