Officials Unclear If Victims Remain in Exploded Conn. Plant

MIDDLETOWN, Conn. | A Connecticut fire official now says it’s unclear whether everyone is accounted for after a massive explosion that killed at least five people at an under-construction power plant.

Middletown Deputy Fire Marshal Al Santostefano had said Sunday night that officials believed no one was missing amid the rubble. But today he said rescue crews still haven’t been able to search a section of the plant that remains unstable, and it was impossible to know if there were victims in that area.

Local fire investigators and federal authorities today were expected to begin their investigation into what caused Sunday morning’s explosion at the Kleen Energy Systems plant in Middletown, about 20 miles south of Hartford.

A dozen or more others were hurt in the blast.

The explosion sounded like a sonic boom and blew out walls of an unfinished power plant and set off a fire during a test of natural gas lines Sunday.

The explosion at the Kleen Energy Systems plant in Middletown, about 20 miles south of Hartford, could be heard and felt for miles.

The explosion left huge pieces of metal that once encased the plant peeling off its sides. A large swath of the structure was blackened and surrounded by debris, but the building, its roof and its two smokestacks were still standing. Rescue crews had set up several tents alongside the site, which is a few miles from Wesleyan University on a wooded and hilly 137-acre parcel of land overlooking the Connecticut River.

The explosion happened around 11:15 a.m., Santostefano said. Mayor Sebastian Giuliano heard the blast.

"It felt almost like a sonic boom," Giuliano said at an evening news conference.

Santostefano said 50 to 60 people were in the area at the time of the explosion, and multiple contractors were working on the project, making it difficult to quickly account for everyone.

One of those killed was Raymond Dobratz, a 58-year-old plumber from Old Saybrook, said his son, Erik Dobratz, who called the elder man "a great dad."

The 620-megawatt plant, which was almost complete, is being built to produce energy primarily using natural gas. Santostefano said workers for the construction company, O&G Industries, were purging the gas line when the explosion occurred.

Officials had not released the conditions of the injured people by Sunday evening, although they said at least a dozen people had injuries ranging from minor to very serious.

The thundering blast shook houses for miles.

"I felt the house shake. I thought a tree fell on the house," Middletown resident Steve Clark said.

Barrett Robbins-Pianka, who lives about a mile away and has monitored the project for years, said she was running outside and heard what she called "a tremendous boom."

"I thought it might be some test or something, but it was really loud, a definite explosion," she said.

Work on the plant was 95 percent complete, the mayor said.

Kleen Energy Systems LLC began construction on it in February 2008. It had signed a capacity deal with Connecticut Light and Power for the electricity produced by the plant, which was scheduled to be completed by mid-2010.

The company is run by former Middletown City Councilman William Corvo. A message left at Corvo's home was not returned Sunday. Calls to Gordon Holk, general manager of Power Plant Management Services, which has a contract to manage the plant, also weren't returned.

Energy Investors Funds, a private equity fund that indirectly owns a majority share in the power plant, said it is fully cooperating with authorities investigating the explosion. In a written statement, the company offered sympathy and concern and said it would release more information on the explosion as it becomes available.

Gov. M. Jodi Rell visited the scene Sunday and announced late in the day that the state had imposed a temporary no-fly zone for a three-mile radius around the site to ensure that the safety of the search and rescue workers would not be jeopardized. The restrictions were put in place until this evening.

The state's Emergency Operations Center in Hartford also was activated, and the Department of Public Health was called to provide tents at the scene for shelter and medical triage.

Daniel Horowitz, a spokesman with the U.S. Chemical Safety Board, said the agency is mobilizing an investigation team from Colorado and hopes to have the workers on the scene today.

Plants powered by natural gas are taking on a much larger role in generating electricity for the United States. Gas emits about half the greenhouse gases of coal-fired plants and new technology has allowed natural gas companies to begin to unlock gas supplies that could total more than 100 years at current usage levels.
