PERMIT NUMBER:
MTX000164
A determination has been made by DEQ to modify and reissue an existing Montana Ground Water Pollution Control System (MGWPCS) permit, MTX000164, to Alpine Pacific Utilities, LLC for the Glacier Ranch Subdivision. This permitting action authorizes discharge of treated wastewater to ground water. The scope of this permitting action is for the operation and maintenance of the wastewater treatment and disposal systems.
The existing wastewater system currently services the Glacier Ranch Subdivision. A planned expansion proposes to: add wastewaters from the Glacier Park International Airport, expand treatment capabilities, and add new disposal capacity. All wastewater will undergo treatment and subsurface disposal. The existing drainfield (Outfall 001) located within the subdivision will be maintained as is. The location of the two new drainfields (Outfall 002 and Outfall 003) will be established within airport property.
The centralized and expanded wastewater treatment system will be located at the same location as the existing treatment system, within the Glacier Ranch Subdivision.
