# SUPPLEMENTARY INFORMATION:

The Draft Environmental Impact Statement (DEIS) was prepared to address rehabilitation of the wastewater treatment system that currently serves the west side of Glacier National Park (Park). The service area for the existing wastewater treatment plant (WWTP) includes Park Headquarters and residences, campgrounds, Lake McDonald Lodge, and concession businesses and employee housing. The existing WWTP is no longer meeting its original treatment objective or operating at design capacity.The preferred alternative (Alternative 3) is to construct an advanced WWTP, with a land discharge site. This alternative would provide the greatest level of treatment and the highest water quality of the alternatives considered. Minimal new site disturbance would be necessary to implement the preferred alternative and the existing spray field in the floodplain of the Middle Fork of the Flathead River and McDonald Creek would no longer be used. Alternative 1A includes construction of an additional storage lagoon and a new spray field to discharge treated effluent. This would require clearing 6.5 hectares of undisturbed land and the existing spray field would continue to be used. Alternative 1B includes construction of two new storage lagoons and an additional aerated lagoon (3.6 hectares). The existing spray field would continue to be used. Alternative 2A includes construction of an advanced WWTP and a series of three rapid infiltration basins (3.6 hectares) to discharge treated effluent to the ground water. The existing spray field would no longer be used. The no action alternative (Alternative 4) would continue operation of the existing WWTP and spray field. Occasional raw sewage spills are possible when storage capacity is exceeded and the spray field cannot be operated because of wet conditions. The details of the alternatives and potential impacts to wildlife, vegetation, and threatened and endangered species and benefits to water quality and Park and concession operations are described in this document and are summarized in Table 2. Estimated costs to implement the alternatives are presented in Table 1.
