A former local official has pleaded not guilty in Vermont Superior Court to a charge of driving under the influence of alcohol on Interstate 89 in Colchester after he crashed his car into an Vt. Agency of Transportation plow truck three months ago, police say.

Herbert A. Durfee III, 55, of Grand Isle had an estimated alcohol level of .111 percent when his car collided with the 2012 plow truck as it spread salt about 1:12 a.m. February 10, state police said in court papers.

Durfee has spent much of his career in public service, including as the community development director for Essex Town for five years and with the Chittenden County Regional Planning Commission for 10 years.

He has been town manager of Norwich for the past year and previously worked as town manager in Fair Haven for four years.

The Colchester Center Volunteer Fire Department freed Durfee from the wreckage. He had various injuries, including a collapsed lung, and was unconscious after the crash, police said.

Police said they had to obtain a search warrant from a judge to get blood drawn from Durfee when he was taken to the University of Vermont Medical Center.

By calculating back to the time of the crash, a chemist reported Durfee had a projected alcohol level of .111 percent, court records show.

Cynthia Provost, 41, of Essex Jct., was driving southbound in the large state dump truck when it was struck from behind, police said. They said she was not injured.

Police said in February initial reports showed Durfee tried to pass the truck on the right, striking the passenger-side plow wing, police said. His car was totaled in the crash.
