A new company has stepped forward with interest to operate a methadone clinic at the former Turning Tide location.

Rockland Metro Treatment of Maine sent a letter to the city on June 10 saying it was the proposed tenant for the property at 166 New County Road. Rockland Metro is a subsidiary of Colonial Management Group LP, which operates methadone clinics across the country.

Discovery House had previously expressed its interest in locating there following the closure of the Turning Tide clinic on Aug. 19, 2010.

The city council is scheduled to consider a preliminary vote Monday evening, June 13 on a proposal to create a conditional zone at the location to allow for a methadone clinic. Colonial, however, is asking for changes in some of the conditions proposed by Rockland.

One condition that Colonial seeks to have changed is one that prohibits the methadone clinic from employing anyone who has a drug conviction.

“Some individuals who work at these clinics are recovering addicts. They understand the psychology of the individual who is being treated and, after having been through successful treatment, are very effective employees,” the letter from Colonial’s attorney Steven Brickman states.

Turning Tide closed in August when the U.S. Drug Enforcement Administration closed it, citing an imminent threat to the health and safety of the public. That closure followed the arrest of its owner and a drug counselor for drug possession.

Colonial also asked that the hours of operation be more than in the proposed zone. The city has proposed operating hours of 5:30 a.m. through 1:30 p.m. each day but Colonial would like that expanded to 2 p.m.

Colonial, based in Orlando, Fla., operates 57 clinics across the country. The company has one in Bangor — Penobscot County Metro Treatment Center.

The proposal for a conditional zone change to allow for a methadone clinic came from Ann Tuttle, the owner of the site that had been leased by Turning Tide.

In March, the city council rescinded the conditional zone that allowed Turning Tide to operate a methadone clinic. The council ruled that Turning Tide had violated conditions of the contract zone that had been established in January 2006 following a federal civil rights lawsuit by Turning Tide after Rockland refused to allow methadone clinics anywhere but on the city’s one-half mile stretch of Route 90.

Colonial’s proposal is the second one considered in the region. A proposal for one in Warren stalled when voters enacted a moratorium to allow for that town’s planning board to come up with regulations. CRC Health Group, which proposed a methadone clinic at the former Warren school building, filed a federal lawsuit in May against the town, claiming a violation of the Americans with Disabilities Act.
