Timpanogos Special Service District (the Project Proponent) proposes to expand the Timpanogos Special Service District (TSSD) wastewater treatment facility (Proposed Project).Currently
the wastewater facility services the cities of Alpine, American Fork, Cedar Hills, Eagle Mountain, Highland, Lehi, Pleasant Grove, Saratoga Springs, Vineyard and part of Draper. The
Project Proponent indicates that the Proposed Project is needed to meet the future projected population growth. The wastewater facility is necessary to meet the future wastewater treatment
demands. The Project Proponent indicates that the current facility capacity is insufficient to meet the growth of the region. The Proposed Project would include the construction and
operations of new treatment process building for the removal of phosphorus, a new pump station, chemical building and an ultraviolet facility for disinfection from the final effluent
before discharging into Utah Lake. The Proposed Project will impact approximately 3.02 acres of palustrine emergent wetlands that were previously constructed as compensatory wetland
mitigation for an expansion of the wastewater treatment facility in the mid 1990’s. The Project Proponent proposed to restore and enhance approximately 19.5 acres of existing wetland
habitat located at the north end of the project area for the required compensatory mitigation. The compensatory mitigation details for the plan are still under USACE review.
