SPA 124 Permit Decision Notice: City of Billings West End Water Treatment Plant – Hogan Slough Water Transmission Main

Jul 25, 2024 8:10 AM

The City of Billings proposes to install a water transmission main to efficiently transfer water from the West End Water Treatment Plant (WTP) up to the West End and Heights communities of Billings. Population growth has substantially increased in the Billings area in recent years, which has led to an increasing demand for reliable drinking water. The WTP transmission main project involves the installation of a new, 36-inch transmission main to connect to the new West End Water Treatment Plant (currently under construction) in the City of Billings. The transmission main will transect Hogan's Slough and an associated fringe wetland at the south side of the Shiloh Conservation area. The City proposes to install transmission main via trenching under Hogan’s Slough, and water in Hogan's Slough will be temporarily re-routed via piping or open channel through a temporary channel. The City proposes to implement the transmission main project mid-September 2024 and complete the project by December 2024.

Based on the environmental review provided in the Draft EA, and, to the greatest extent possible, in accordance with all applicable laws, rules, regulations, and policies, FWP determined the proposed action (Alternative 2), will not have significant adverse impacts on the human environment associated with the proposed action and constitutes a reasonable and appropriate strategy to achieve identified objectives. Therefore, preparation of an environmental impact statement or EIS is unnecessary.

FWP hereby adopts the Draft EA as final and approves Alternative 2, the Proposed Action.
