Gas blast at Conn. power plant kills at least 5

MIDDLETOWN, Conn. (AP) - An explosion blew apart a power plant
under construction as workers purged natural gas lines Sunday,
killing at least five people and injuring a dozen or more in a
blast that shook homes for miles, officials said.
Middletown Mayor Sebastian Giuliano said at a late-afternoon
news conference that at least 12 people were injured.
Deputy Fire Marshal Al Santostefano told The Associated Press
before a news conference Sunday evening that crews were still
searching for survivors in the rubble at the Kleen Energy Systems
plant in Middletown, about 20 miles south of Hartford.
Santostefano earlier said about 50 people were in the area
around 11:17 a.m., when the explosion occurred. The mayor said at
the news conference it was difficult to tell how many people were
at the plant because multiple contractors were working on it with
their own employee lists.
"They're trying to figure out who was on the job today, and
where are they now?" Giuliano said.
The 620-megawatt plant was being built to produce energy
primarily using natural gas. Santostefano said workers for the
construction company, O&G Industries, were purging the gas lines, a
procedure he called a "blow-down," when the explosion occurred.
Lynn Hawley, 54, of Hartland, Conn., told the AP that her son,
Brian Hawley, 36, is a pipefitter at the plant. He called her from
his cell phone to say he was being rushed to Middlesex Hospital.
"He really couldn't say what happened to him," she said. "He
was in a lot of pain, and they got him into surgery as quickly as
possible."
She said he had a broken leg and was expected to survive.
Officials had not released the conditions of the other injured
people by late Sunday afternoon, but hospitals reported some
seriously injured patients.
The thundering blast shook houses for miles.
"I felt the house shake, I thought a tree fell on the house,"
said Middletown resident Steve Clark.
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.
Kleen Energy Systems LLC began construction on the power plant
in February 2008. It had signed a capacity deal with Connecticut
Light and Power for the electricity produced by the plant.
Construction was scheduled to be completed by mid-2010.
The company is run by president and former Middletown City
Council member William Corvo. A message left at Corvo's home was
not immediately returned.
Calls to Gordon Holk, general manager of Power Plant Management
Services, which has a contract to manage the plant, weren't
immediately returned.
Plants powered by natural gas are taking on a much larger role
in generating electricity for the U.S. 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.
Natural gas is used to make about a fifth of the nation's
electricity.
Gov. M. Jodi Rell planned to visit the scene Sunday and called
out a specialized search and rescue team to help firefighters.
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.
Rell said the emergency teams were expected to work through the
night and into Monday.
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 Monday.
Safety board investigators have done extensive work on the issue
of gas line purging since an explosion last year at a Slim Jim
factory in North Carolina killed four people. They've identified
other explosions caused by workers who were unsafely venting gas
lines inside buildings.
The board voted last week to recommend that national and
international code writers strengthen their guidelines to require
outdoor venting of gas lines or an approved safety plan to do it
indoors.
In February 2009, an explosion at a We Energies coal-fired power
plant near Milwaukee burned six workers. The Occupational Safety
and Health Administration is still investigating.
In the past few years, an explosion at a Dominion Virginia Power
coal-fired plant in Massachusetts killed three workers in November
2007, while one worker and nine others were injured at an American
Electric Power plant of the same type in Beverly, Ohio, in January
2007.
