Because the Olentangy River is designated as a State Scenic River, an OEPA Section 401 Water Quality Certification was also required. By demonstrating impacts to water quality would be minimal under the pier removal processes to be employed, L&A was able to obtain an OEPA NWP D.5 Directors Authorization waiving this WQC requirement on behalf of the County. USACE authorized the NWP without comment.
