Gorham Planning Board will hold another public hearing on a request for an asphalt plant and quarry, at 7 p.m. on Monday in the Gorham Municipal Center, 75 South St.

Shaw Brothers Construction Inc., is proposing a multi-million plant on a 125-acre site zoned industrial on Mosher Road. The construction company would replace an initial portable plant eventually with one valued at $10 million.

The project was introduced last year and a series of public hearings have been packed.

Opponents argue the site off Mosher Road is the wrong place for an asphalt plant and quarry, because it’s too close to residential areas. They argue the noise, traffic and and potentially hazardous emissions would affect the quality of life of the people who live nearby.

However, supporters argue that as long as the plant and quarry comply with local ordinances and meet state and federal air emissions standards, it should be allowed. In addition to the approval of the Gorham Planning Board, the plant will also need an air emissions license by the Maine Department of Environmental Protection, which would monitor the project. Proponents also believe the plant will provide economic benefit to the town.

The proposed site is zoned industrial. Clay was once mined in the area for bricks, which were manufactured at the site. The construction company bought the bulk of the parcel from Lachance Brick Co., which retained its buildings and a small parcel to market bricks.

Shaw Brothers recently offered a revised version of the plan to ease neighborhood opposition. The company would move the plant behind the Lachance Brick Co. buildings, back from Mosher Road and farther away from Queen Street. The original plans located the plant beside the brick company and closer to Queen Street.

Danny Shaw, a co-owner of the company, said during a public hearing earlier this month he hoped neighbors would agree that the revision had addressed their concerns.

“We take our responsibility to the town seriously,” he said. “We are confident it will be a good thing for the town.”
