MINOT — Suggestions to regulate noise at mass gatherings were debated at a hearing by the Board of Selectmen on Monday night.

The Planning Board will present a mass gathering ordinance to voters at the annual town meeting in March, in response to complaints from residents about noise from the Great North: Music and Festival at Hemond Motocross Park last month.

Residents affected by the loud, late-night music over four nights favored the Planning Board’s proposal to cut off all amplified music at midnight on Fridays and Saturdays and at 10 p.m. all other nights.

John Hicks, representing the interests of 456 Presents and Great North: Music and Festival, offered recommendations for Friday and Saturday nights that call for no restrictions on sound before midnight but restrictions from midnight to 2 a.m.

On Thursday and Sunday nights there would be no sound restrictions before 10 p.m., but there would be from 10 p.m. to midnight on Thursday nights, he suggested.

Hicks also requested a 30-minute grace period for Thursday, Friday and Saturday nights.

And he suggested that lowering the sound somewhat from midnight to 2 a.m. and allowing “silent disco” after 2 a.m. was realistic.

“Realistic for you, maybe,” resident Marie Ouellette said.

Michael Hemond, owner of the motocross park, suggested Hicks’ recommendations be tried for a year.

Recognizing how difficult, contentious and expensive it is to monitor noise, it was agreed that limiting how long loud music could be played was by far the more practical approach.

Planning Board Chairwoman Candace Gilpatric said the board is considering fines, similar to those imposed by Bangor and Portland at outdoor concerts, as a means to curb violations.

Steve French, chairman of the Board of Selectmen, said the board will develop an ordinance to be presented at the annual town meeting in March.

“I will enforce any ordinance that is approved. I will make sure it is followed,” Hemond said.
