SOUND: A Central Maine Power Co. official says the company is taking seriously residents’ concerns about noise from the company’s Benton substation, but that solutions to the noise problems take time.

Scott Cyrway, a former Kennebec County deputy sheriff, described the noise as the humming you’d hear if you were inside a jet plane.

It woke up Selectwoman Melissa Patterson at 4 a.m. the other morning; she described it as a car idling outside your window.

About 10 to 15 people living near the Central Maine Power Co. substation in Benton have been bothered by a persistent humming or buzzing noise since May, when the machine was first turned on. Irritated residents called CMP to address the issue but have been met with delayed responses and push-back, according to Selectman Antoine Morin.

“CMP says it’s looking for a solution, but at this point it’s dragging its feet,” Morin said. “We’ve made our frustration known to CMP about this issue.”

Residents and the town have been working on potential solutions, but they think CMP has been failing to rectify the problem. CMP, however, said it is taking the concerns the residents have seriously, but solutions to such problems take time.

The substation, which takes higher-voltage current and steps it down to a lower voltage before it is distributed further, is an intricate piece of machinery that includes transmitters, generators, antennas, towers and wires enclosed by a chain-link fence. It’s about a half-mile from the intersection of Albion and East Benton roads, between Blaisdell Lane and Patterson Road.

“The equipment makes a steady hum as it operates,” CMP spokesman John Carroll said. “It’s a really important part of our system.”

The substation was built as a part of the Maine Power Reliability Program, a project started by CMP in 2010 to modernize its power system. While the noise is a consequence of the substation’s operation, it is supposed to remain within the town ordinance limit of 55 decibels during the day and 45 at night. The nighttime limit of 45 decibels is a little below the sound of normal conversation and is recommended by the Maine Department of Environmental Protection. The substation has stayed within those parameters, Carroll said.

“We tested our equipment to stay in line with town and state ordinances and confirmed that we met those standards,” Carroll said.

The Board of Selectmen and residents have disputed CMP’s readings and said the company cherry-picked the time and days it tests for sound.

“They keep coming back and saying that they’re under 45 decibels, so tough luck,” Morin said. “We feel the reports have been flawed because they did them at their own discretion and time.”

Those tests were in August, after representatives from CMP met with concerned neighbors and the selectmen. After those test results were reported a couple weeks later, CMP met again with the town to discuss taking readings at residents’ properties. Those tests took place Nov. 20, and Carroll expects the results in the next couple of weeks.

“We’re committed on going back when the results are in and talk to the residents and town about what is next,” Carroll said. “That will tell us what sort of issue there is, what the extent of the problem is. We’re going through the process, and I understand residents are frustrated, because it’s a slow process.”

In the meantime, the board gave residents affected by the noise their own sound meters to measure the bothersome sound.

Strohman, 43, is a retired anesthesiologist who has Parkinson’s disease. Adapting to the disease made it hard enough for her to sleep as it was, but with the persistent noise from the substation, now it’s a nightmare.
