Here is an article about more wind projects that have been approved by the FAA after determining that they do not interfere with radar. The concern with radar arose earlier this year, haulting many projects, but has been steadily dissipating as studies are conducted. Study after study demonstrate that proper placement of wind turbines allows the turbines and radar equipment to operate normally, without any interference.

FAA gives go-ahead to three Minnesota wind projects

WASHINGTON - The Federal Aviation Administration has given the go-ahead
to three Minnesota wind power projects, after concluding that they don't
interfere with military radar.

The approvals were announced Thursday by Sen. Norm Coleman, a Minnesota
Republican who urged the FAA to approve the projects. The FAA confirmed
the projects had been given the go-ahead.

More than a dozen wind developers in the Midwest had been told earlier
this year that their projects might not get safety permits because of
the potential impact on military radar.

The three Minnesota projects that have been approved are: PPM Energy,
enXco Energy and Wind Energy Developers.

Jan Johnson, a spokeswoman for PPM Energy, said the company got a
determination of "no hazard" from the FAA a couple of weeks ago. That
will pave the way for construction to begin this year on a 150-megawatt
project in Lincoln County in Minnesota, and Brookings County, South
Dakota, she said.

Johnson said that the project would provide enough energy to power about
45,000 homes a year.

Officials with enXco Energy and Wind Energy Developers did not return
telephone messages left Thursday.

The enXco project would be built near Chandler. Spokespeople for the FAA
and Coleman's office weren't immediately sure where the Wind Energy
Developers project is located. The company's Web site and state and
local government records indicate the company is developing projects in
both Cottonwood and Murray counties.

"Hundreds of millions of dollars in wind development, much-needed jobs
in southwestern Minnesota, and abundant clean, renewable energy can now
become a reality thanks to the FAA clearing the way for three Minnesota
wind projects," Coleman said in a statement.

FAA spokeswoman Diane Spitaliere confirmed the three had been given
clearance.

"There were some issues with those projects, but we worked very closely
with the applicants to mitigate any safety factors so that they could go
ahead with their projects," said Spitaliere, who did not have details on
the specifics of the mitigation.

The American Wind Energy Association, a Washington trade group, ranks
Minnesota fourth in the nation in the amount of wind energy installed.
