LIVERMORE – Residents have a chance Wednesday to learn about a newly proposed noise ordinance and amendments to five existing ordinances at a public hearing before voting on them at the annual town meeting June 14.

The hearing begins at 7 p.m., Wednesday at the town office.

Planning Board members started working on a noise ordinance after residents requested noise restrictions on an all-terrain park on Route 108. After some controversial debate, the board sent for a legal opinion to determine if they could put restrictions on noise levels for the park, since there was no wording specifically targeting noise.

They learned they couldn’t address noise levels unless a provision was put in an ordinance.

The town’s Board of Appeals conducted its own review of the all-terrain park’s application and determined a permit should be granted and recommended that an ordinance be drafted to address noise levels in the future.

The Planning Board’s ordinance states its purpose is to protect the public from unreasonable increases in noise from certain commercial, industrial, manufacturing and assembling operations.

The standards would apply to proposed or existing commercial, industrial or manufacturing uses that require Planning Board site review for the use or expansion of machinery, fabrication, assembly, outdoor processing and manufacturing.

Examples of such uses, according to the proposal, includes machine shops, sawmills, vehicle repair facilities, welding shops and livestock confinement feeding operations.

It would not apply to retail and professional office, governmental or forest management activities, or traditional agricultural uses.

Residential noise levels should not exceed 50 decibels between the hours of 10 p.m. and 7 a.m., according to the ordinance.

Amendments are being proposed to five ordinances: building, mobile home park, shoreland zoning, site plan review and subdivision.

The amendments are an attempt to clarify sections dealing with the appeal process.
