Ryan Incorporated Central is one of the nation's most experienced environmental contractors, with an extensive resume of new landfill construction as well as remediation and closures. Sitework associated with ash landfills and power plants has been a central part of our expertise for over 50 years. Our large equipment fleet, experienced personnel, safety, and speed have put us at the forefront for sitework, including infrastructure within and around ash landfills (new construction and capping).  In addition to the ash landfill impoundments, we have worked extensively in closing existing ash ponds using both clean closure and close-in-place methods. 

All of our field people are highly-trained, including 40-Hour HAZWOPER and annual 8-hour refreshers, Excavation Competent Person, Confined Space, Standard First Aid and other programs. The formal training combined with the scores of projects completed make our people among the most experienced in the industry.
