ODOT HAN-75-14.39 Bridge Replacement / Blanchard River Mussel Survey – ASC Group – Findlay, Hancock County, Ohio

As part of bridge replacement plans, STONE performed a mussel survey and relocation in the vicinity of the Interstate Route 75 Bridge over the Blanchard River.  An initial survey of the mussels at this location found 13 species of mussels in the vicinity of the bridge, including one species (Truncilla truncata) listed as a Species of Concern in Ohio.  All stream habitats (not just suitable habitats) were then visually inspected, with special attention paid to substrates that could support living mussels. Aquascope viewers were employed during the survey to aid in viewing the substrates.  In total, 637 live mussels were relocated following the Ohio Mussel Survey Protocols for Group 1 streams (USFWS & ODNR 2016).  These included no threatened or endangered species and four species of concern. The survey was conducted within a short time frame so as to fit within the approved field season (prior to October 1) and included coordination and approval with the Ohio Department of Natural Resources.

“Bayshore Environmental is very pleased to have engaged STONE to conduct a Phase II assessment of a contaminated commercial property.  The technical staff at STONE worked with us to develop an excellent program that entailed soil and groundwater sampling, testing and removal of drums of waste petroleum products, and the remediation of contaminated soil.  STONE conducted the work in a timely manner, produced an excellent report that was tailored to meet our needs, and all at a very reasonable cost.  We are pleased to endorse STONE and look forward to working with them in the future.”
