State environmental regulators are in closed-door talks with the owners of a Billerica recycling company in an attempt to end alleged violations at the 24-hour facility that have been the source of frustration for town officials and neighbors for years.
Empire Recycling LLC has been under fire from state and local environmental officials since 2011 when the company was cited for noise generated by round-the-clock recycling operations at the Sterling Road facility and for processing materials outside in violation of state solid-waste regulations.
State and town officials said the violations continue and nearby residents say they are still being subjected to nightly noise from the site and are becoming increasingly concerned about health issues.
“It’s been a struggle for several years,” said Richard Berube, the town’s public health director, of repeated efforts to get Empire Recycling to follow the rules. “We’ve been trying to get them to come into compliance without taking more drastic action but we don’t seem to be making progress.” Full story for BostonGlobe.com subscribers.
