Selectmen are expected to vote on whether to extend the moratorium on methadone clinics in the town during the meeting Wednesday, June 1 at the town office. The meeting will start with a public hearing.

The meeting is set to start at 7 p.m.

Residents will have an opportunity to ask questions and raise concerns about the issue.

In the event that a large number of people show up, the meeting will be moved from the town office to the fire station, according to Town Manager Grant Watmough.

Watmough said the meeting was planned before it was reported that CRC Health Group filed a lawsuit in U.S. District Court against the town of Warren seeking to overturn the town’s moratorium on methadone clinics and permission to operate in the town.

The lawsuit asks the court to prevent the town from applying its moratorium to CRC and its patients. In addition, it asks the court to order the town to treat CRC’s proposed clinic as a permitted use and grant CRC’s request for reasonable accommodation under the Americans with Disabilities Act. The company is also seeking “frustration of mission damages,” costs and attorneys’ fees.

CRC Health Group proposed opening a methadone clinic in the former school on School Street after businessman Robert Emery entered into a purchase-and-sale agreement to buy the school from the town through his company Vixen Land Holdings LLC.

Residents voted at a special town meeting to enact a moratorium on methadone clinics to provide a town committee with time to revise its ordinances to deal with such facilities.

The lawsuit was filed earlier in May listing CRC Recovery Inc. and CRC Health Group as plaintiffs, represented by attorneys James Green of West Palm Beach, Fla., and Walter McKee of Augusta.

CRC attorneys claim the moratorium and the town’s reaction to the proposed methadone clinic violate the ADA law, arguing it is unlawful for local government to treat substance abuse treatment programs differently from other health or medical care services. The attorneys also argue the town has to make reasonable accommodation from its zoning laws for the facility.
