FeeFee Trunk FF-15 Sanitary Sewer Relief

Location: Maryland Heights, Missouri
Client: BIS Frucon Engineering
Owner: MSD
Services: Water Resource Management, Environmental

Geotechnology has assisted BIS Frucon with environmental consulting, planning and data interpretation of contaminated environmental media, stream bank stabilization, and natural systems assessment tasks for this project. In addition, geomorphological observations were performed to evaluate stabilization recommendations, including composite revetment layered with native plantings, turf-reinforcement mats with native plantings, and grade control structures. As part of continued services Geotechnology is assisting with acquisition of the projects’ 404 and 401 permits. Geotechnology conducted a Sunshine Act file review and met with Missouri Department of Natural Resources (MDNR) personnel to develop a hazardous waste delisting request and work plan with the anticipation of minimizing construction costs associated with new sewer installation. In August 2011 Geotechnology received a letter from MDNR that officially delists the soil, groundwater and bedrock from being a listed hazardous waste. The implication of this delisting is significant: soil, groundwater and bedrock generated during the construction of the new sewer alignment will not be considered hazardous waste. The handling/disposal effort and costs associated with this designation will thus be greatly reduced.
