OMAHA, Neb. (AP) — Omaha Public Power District officials say it will cost $5 million to end what was supposed to be a 20-year-contract with the company that has managed day-to-day operations at the Fort Calhoun nuclear power plant since 2012.

The power district began permanently shutting down the nation’s smallest nuclear power plant on Monday. It’s one of the first steps of a decommissioning process that could last decades.

Exelon Generation has managed Fort Calhoun since September 2012, when it stepped in to bring the nuclear plant back from a nearly three-year outage. The utility would have paid $400 million to Exelon if it had completed its licensing term in 2033.

A utility spokeswoman says it is unclear when the contract will be terminated.

SOUTH SIOUX CITY, Neb. (AP) — A city administrator says a company is taking steps to eliminate a horrible odor that’s some residents say has forced them to temporarily leave their South Sioux City neighborhood.

The odor primarily has affected 15 houses in a five-block area where about 40 people live. City Administrator Lance Hedquist said Monday the odor originates at the Big Ox Energy plant about two miles away. He says sewage from the homes and the plant meet at a lift station that sends the sewage to the sewer plant.

Hedquist said Big Ox intends to begin adding to its sewage outflow a chemical that should end the problem.

Denmark, Wisconsin-based Big Ox converts organic waste into methane gas. A company spokesman didn’t immediately return a call from The Associated Press.

OMAHA, Neb. (AP) — Top executives at Goodwill Omaha receive higher salaries than peers at area nonprofits and at other Goodwills nationwide.

Goodwill Omaha CEO Frank McGree received total compensation of $933,444 in 2014. More than half of that was a $519,000 one-time retention bonus, but even without that McGree’s pay was higher than many nonprofit executives.

Thirteen of the nonprofit’s executives were paid more than $100,000 salaries in 2014, so a significant portion of the $4 million generated from Goodwill’s stores in eastern Nebraska and western Iowa went to administrative costs instead of Goodwill’s job training programs.

McGree’s compensation sits in the top tier among 150 independent Goodwill affiliates nationwide. Only two dozen Goodwill leaders make over $400,000 a year and two receive pay over $1 million.

OMAHA, Neb. (AP) — The nation’s smallest nuclear power plant is set to permanently shut down on Monday.

The Omaha Public Power District’s board decided earlier this year that the Fort Calhoun nuclear power plant is no longer financially sustainable.

But the shutdown is only one of the first steps of a decommissioning process that could stretch on for as many as 60 years and cost more than $1 billion.

During that process, the utility will have to decontaminate and disassemble elements of the power plant.

The nuclear plant sits on the Missouri River across from Iowa and is about 15 miles north of Omaha.

COUNCIL BLUFFS, Iowa (AP) — A former Nebraska jail employee has been found guilty in western Iowa of child sex and pornography counts.

A Pottawattamie County jury found Shawn Beu guilty Friday on all 10 counts related his sexual abuse and video recording of young girls.

Prosecutors say videos of Beu sexually abusing a young girl and of young girls taken on a hidden camera in Beu’s bathroom were found in his home. The 37-year-old Beu had claimed he did not take the videos.

Beu, who lives in Council Bluffs, was a corrections sergeant at the Douglas County Jail in Omaha when he was arrested in March. He faces up to 100 years in prison when he’s sentenced Nov. 30.

OMAHA, Neb. (AP) — Events this weekend will go on as planned at Omaha’s Holland Performing Arts Center, despite a city bus crashing through its glass-walled exterior.

The crash happened Friday night after police say an SUV ran a red light and hit the bus. That sent the bus into the downtown Holland Center.

Police say the driver of the bus was taken to a hospital. Her medical condition was not known Saturday.

Officials say the crash happened after crowds had left the Holland concert hall for a Friday night symphony performance. No one was injured outside the bus or in the center.

SOUTH SIOUX CITY, Neb. (AP) — A foul odor tied to a sewage line in South Sioux City has sickened some residents and forced some to flee their homes as officials look for a remedy.

South Sioux City administrator Lance Hedquist tells the Sioux City Journal (https://bit.ly/2esC7lr ) that the odor is coming from 15 houses in a five-block area of a neighborhood where about 40 people live.

Hedquist says there’s also a “horrific” odor coming from the Big Ox Energy plant, which recently started operations in the city’s Roth Industrial Park about two miles from the affected houses.

Big Ox, a Denmark, Wisconsin-based renewable energy firm, converts organic industrial waste into methane gas.

Hedquist said Friday that the new plant and the homes share the same sewer line.

DECATUR, Neb. (AP) — The occupants of all but one northeast Nebraska house have been allowed to return to their homes days after they were evacuated because of an anhydrous ammonia leak that killed a local farmer.

Magellan Midstream Partners, of Tulsa, Oklahoma, made that announcement Saturday.

Magellan has been repairing an 8-inch-diameter pipeline that carries anhydrous ammonia, used as a farm fertilizer. When released from a tank or pipe, it becomes a lethal gas that can cause severe chemical burns and damage the tissue of the eyes, nose, throat and lungs.

Authorities have said 59-year-old Phillip Hennig, of Tekamah, was killed by the fumes Monday night while checking on the leak.

Magellan says it is conducting additional air quality testing at each residence as occupants return to ensure safe air quality.

LINCOLN, Neb. (AP) — Two Illinois men have been convicted in Nebraska of possessing 128 pounds of marijuana for sale.

31-year-old Ali Khalil, of Oak Lawn, Illinois, and 30-year-old Issa Abu-Serieh, of Burbank, Illinois, were found guilty after a nonjury trial. They’re scheduled to be sentenced Jan. 23.

Lancaster County sheriff’s deputies say they stopped cars being driven too closely by the two on Jan. 25, 2015, near Lincoln on Interstate 80. The sheriff’s office says the two seemed to be traveling together. A police dog taken to the scene alerted officers to the odor of drugs.

Attorneys for the two later argued the evidence should be suppressed because the traffic stop was merely a pretext to search the vehicles.
