ATC Group Services LLC (“ATC”) has agreed to acquire Environmental Compliance Services (“ECS”), a leading multi-regional provider of environmental consulting, site remediation and regulatory compliance services.

Founded in 1982 with headquarters in Agawam, Mass., ECS has more than 250 employees operating out of 27 offices in 15 states and provides a range of environmental services, with a particular focus on the retail petroleum market and associated underground storage tank inspection, remediation and regulatory compliance.

“Environmental consulting is the heart of ATC’s business, and ECS’s expertise and service offering are a perfect addition to our existing environmental capabilities,” said ATC CEO Bobby Toups. “ECS’s strong customer base is highly complementary to our own, so by joining forces we will be better positioned to drive growth and deliver an even broader portfolio of environmental services to our valued customers. On behalf of everyone at ATC, I want to extend a warm welcome to the ECS team. We are delighted to have their talented employees join the ATC family.”

As a result of the planned acquisition, ATC will grow to more than 1,900 employees across more than 115 locations, further expanding the company’s national footprint. ECS will continue to be led by Mark Hellstein, ECS’s current president and CEO.
“Having worked closely with ATC in the past, I am confident that they are the best partner to accelerate our growth moving forward as we expand into new markets,” said Hellstein. “We look forward to continuing to redefine consulting, with best-in-class field and customer service.”
