(Official announcement from CTL Engineering)

CTL Engineering is extremely pleased to announce the recent acquisition of Allied Environmental Services, Inc., a former client and subcontractor of CTL.  The acquisition expands CTL Engineering’s service offerings and will strengthen the presence of both companies in the Northwest Ohio region through fresh perspectives, expertise, and talent sharing.

“While acquisitions always require careful thought and consideration, Allied Environmental already shares many of the same values as CTL Engineering, including a commitment to delivering services of the highest quality and a business ethos rooted in strong relationships. We anticipate that both companies will contribute valuable benefits to our overall organization,” said CEO CK Satyapriya.

Both companies have been successful and profitable for many years. The acquisition offers a new opportunity to combine the civil, geotechnical and environmental engineering expertise of CTL with the industrial maintenance and environmental field service capabilities of Allied Environmental to offer a broader suite of service offerings under one umbrella.

“We couldn’t be more excited to be joining the CTL family of companies,” said Steve Carr, Allied CEO. “Allied and CTL have a long history of working together and partnering on projects, so both companies were quite familiar with each other leading into the acquisition. We certainly view this acquisition as a great opportunity for corporate growth.”

Mutual clients of CTL and Allied Environmental have included Cargill, Honda, Marathon Petroleum and Pratt Paper.


Allied Environmental has provided professional environmental field services and industrial cleaning and maintenance to private industry, government, and military facilities, municipalities, schools, and hospitals for 36 years.

Headquartered in Lima, Ohio, their specialties range from industrial cleaning (vac-truck and hydro blasting services), pipeline services, storage tank maintenance, hazardous materials management, emergency spill response, hydro-excavating, asbestos abatement, underground storage tank closure, contaminant remediation, and industrial coatings application.

Allied was founded in 1987 in response to the implementation of the US EPA “Asbestos Hazard Emergency Response Act,” or AHERA. In 1991, Allied was awarded a long-term contract to provide asbestos assessment and abatement to the BP Oil Refinery in Lima, Ohio and has maintained this contract with the refinery for 32 years and through various ownership changes by building a reputation of responsive and quality service.

Since then, Allied has grown its capabilities and its team. Today, they serve clients in Ohio, Indiana, Michigan, Kentucky, West Virginia and Pennsylvania and have a dedicated team of 40 employees.
