HTRW Investigation For Sewer Alignment – Coalton, Ohio

The Sanitary Sewer Replacement project for the Village included 8,862 linear feet of proposed sewer and 22 manhole structures. In order to determine if there were Hazardous, Toxic, & Radioactive Waste (HTRW) concerns, a Limited HTRW Investigation was completed by STONE. The HTRW included review of historical and environmental records, aerial photographs, city directories; as well as a site reconnaissance along the entire proposed sewer corridor. Completion of the HTRW and review by the U.S. Army Corps of Engineers (USACE) allowed the project to move forward.

“STONE performed the ecological survey, environmental sites assessment, wetland delineation, waterway permit for 20 culverts throughout Monroe and Washington Counties. They also prepared the environmental document. We got praises from Ohio Department of Transportation (ODOT) Office of Environmental Services (OES) about their performance. They were a pleasure to work with and were always very responsive.”
