BANGOR – Details continued to come together this week for Maine’s first racetrack casino.

Bangor Raceway, owned by the city of Bangor, is the only site in Maine that won the necessary local and state approval to offer slot machines. The city has a development deal with Penn National Gaming Inc., which plans to break ground next May on a $30 million to $50 million gaming complex.

Over the summer, the Maine Gambling Control Board completed the rule-making process and now is in the homestretch of hiring an executive director.

Public comment on the proposed rules is due by Oct. 7. The gambling panel is slated to consider adopting the rules during a meeting on Oct. 28, when it also expects to review Penn National’s application for a state slots license.

If all goes according to plan, Penn National, which now holds a conditional racing license, will be granted a permanent racing license on Oct. 14 by the Maine Harness Racing Commission.

On Thursday, executive director finalists were being interviewed by a gambling control board subcommittee comprising Jean Deighan, a Bangor investment adviser and lawyer, Dixmont businessman Michael Peters and W. Lawrence Hall, a retired state trooper who now owns a small business in Dedham.

It remains unclear when a nominee for the post, which will pay between $45,926 and $64,147, will be announced. George McHale, chairman of both the racing commission and gambling board, said Wednesday that the director would be brought on board “shortly.”

The proposed rules, developed over the summer, cover everything from licensing operators, vendors and employees to slot machine location and hours of operation.

Among the provisions proposed for the racino are:

. Operating hours would be from 8 a.m. to 4 a.m. daily, except for Sundays, when it would open at noon. It would close for Christmas and Easter. No more than 1,500 slot machines could be installed at Bangor Raceway.

. Automated teller machines would have to be at least 25 feet from the nearest slot machine. The rules prohibit lines of credit.

. Players must be at least 21 years old, though licensed employees could be as young as 18. Licensed employees would be barred from playing, except in the course of training or while demonstrating games for patrons.

. The racino operator and the gambling board each must maintain a list of people excluded from gambling, including those who pose a safety threat, have a documented history of disrupting gaming operations, are on a similar list in any other jurisdictions, are career or professional offenders, have had a gambling-related license revoked or suspended due to disciplinary action, have been convicted of gambling offenses or are the subject of a court order or regulating agency prohibiting them from gambling.

. Firearms would be prohibited, except for on-duty law enforcement officers and armored car personnel.

. Surveillance would be required for all gambling-related activities on the premises.

. Advertising, promotional and marketing campaigns would be subject to prior approval from the gambling board and would be strictly regulated. Ads, for example, cannot include guarantees of success or riches or depict alcohol or tobacco use.

Comments on the proposed rules should be sent to the Maine Gambling Control Board at 87 State House Station, 500 Civic Center Drive, Augusta 04333-0087.
