After spill, pipeline company says new line will be safer

BILLINGS, Mont. (AP) — A Wyoming company said Friday it will replace a pipeline that spilled almost 40,000 gallons of oil into a river in Montana with a new line buried more deeply to protect against future accidents.

The Jan. 17 spill into the Yellowstone River contaminated the water supply for 6,000 residents of Glendive in eastern Montana. The city's water was certified safe to drink on Friday after tests showed it no longer had harmful levels of benzene, a cancer-causing component of crude.

Barriers set up, water tested at site of North Dakota spill

BISMARCK, N.D. (AP) — Earthen barriers have been set up across a creek and water was being tested Thursday around the site of a nearly 3 million-gallon leak of saltwater generated by oil drilling, the largest spill of its kind during North Dakota's current oil rush.

The berms were built at Blacktail Creek to prevent potentially contaminated water from flowing out of the creek and into a bigger body of water that eventually leads into the Missouri River.

Montana city gets OK to drink water after oil spill in river

BILLINGS, Mont. (AP) — Thousands of people in an eastern Montana city were told Thursday they can resume using tap water after tests showed no further signs of contamination from a weekend oil spill into a nearby river.

The 6,000 residents of Glendive had relied on bottled water since Monday after elevated levels of cancer-causing benzene were found in the public water supply. The chemical came from 40,000 gallons of oil that spilled on Saturday from a pipeline breach beneath the Yellowstone River, about six miles upstream of the city.

Montana city to hear if water safe to drink after oil spill

BILLINGS, Mont. (AP) — Initial tests show water supplies in a Montana city show no sign of a cancer-causing element for the first time since they were contaminated by a weekend crude oil spill, a state official said Thursday, raising hopes that thousands of residents can soon start drinking from their taps.

Glendive's water no longer shows elevated levels of benzene, a carcinogenic component of oil, in tests taken from fire hydrants, said Jeni Garcin with the Montana Department of Environmental Quality.

Questions and answers about oil and gas wastewater spills

Nearly 3 million gallons of briny water generated by crude oil production has leaked from a North Dakota pipeline and reached two creeks, making it the biggest spill of this type of wastewater since the state's Bakken formation oil boom began in 2006.

Here are some questions and answers about oil and gas saltwater spills:

Montana oil spill renews worry over safety of old pipelines

BILLINGS, Mont. (AP) — A second large oil spill into Montana's Yellowstone River in less than four years is reviving questions about oversight of the nation's aging pipeline network.

Investigators and company officials on Wednesday were trying to determine the cause of the 40,000-gallon spill that contaminated downstream water supplies in the city of Glendive.

ND official: 3M gallons of saltwater spills, damage unclear

WILLISTON, N.D. (AP) — State officials say nearly 3 million gallons of saltwater generated by oil drilling has leaked from a North Dakota pipeline, though the environmental effects aren't immediately clear.

State health official Dave Glatt said Wednesday that the leak was detected Jan. 6, north of Williston. It's the largest saltwater spill since the state's oil boom began in 2006, and nearly triple the size of the previous record.

Some oil recovered from broken pipeline after river spill

BILLINGS, Mont. (AP) — Workers recovered about 10,000 gallons of oil from a ruptured pipeline that spilled crude into the Yellowstone River and contaminated a Montana city's drinking water.

An estimated 40,000 gallons is still in the river and will be difficult to extract because of a thick layer of ice.

Past, future effects of oil argued in BP penalty trial

NEW ORLEANS (AP) — The 2010 BP oil spill's long-term effects on Gulf of Mexico sea life and coastal marshes remain uncertain, an environmental expert testified Wednesday as federal attorneys laid out their case for penalties against the oil corporation that could hit $13.7 billion.

Donald Boesch, a professor at the University of Maryland, testified for the Justice Department, which is pressing for high penalties against the oil giant. Aside from the obvious harm — among his examples were oiled wildlife, fouled coastal marshes and damage to mangroves — Boesch recounted potential harm to sea life populations based on the effect of oil on microbes at the bottom of the natural food chain.

City tries to repair contaminated water system after spill

GLENDIVE, Mont. (AP) — Authorities were scrambling to decontaminate a water treatment plant serving 6,000 eastern Montana residents after a cancer-causing component of oil was found downstream of a Yellowstone River pipeline spill.

Up to 50,000 gallons of crude were released in Saturday's spill.
