AQUATIC RESOURCE DESCRIPTION: The Penitentiary Canal is situated between the Boise River and E. Warm Springs Avenue in East Boise, Idaho. The canal was dug in 1908-09, beginning at the Boise River Diversion Dam and Power Plant, and generally flowing north/northwest to the Idaho Penitentiary where it originally terminated. Currently the canal is in use for approximately five miles, and is diverted to a secondary ditch which discharges into the Boise River.

This segment of the canal primarily consists of an earthen ditch cut into the slope, and is confined by the existing paved greenbelt pathway to the west, and an abrupt upland hillslope to the west. The ditch slightly varies in width but has an average of 6 feet across. The sides of the canal consist of emergent wetlands consisting of grasses and sedges, with minor segments contains scrub-shrub and forested wetlands.

ANTICIPATED IMPACTS ON AQUATIC ENVIRONMENT: The proposed project would result in the permanent fill of 0.3 acres of wetlands (0.268 PEM, 0.015 PSS, and 0.017 PFO). In addition approximately 1 acres of open water channel will be piped in a similar alignment. No reduction of irrigation flow or delivery are proposed from this project. 

OTHER AUTHORIZATIONS: Currently, we are coordinating with the Tribal Historic Preservation Offices for the Shoshone Paiute, and the Shoshone Bannock Tribes to determine if there are any tribal historic or cultural interests within the project area.  

CULTURAL RESOURCES: Consultation has been completed by the by the Bureau of Reclamation (the Lead Federal Agency) with the office of the Idaho State Historic Preservation Officer to determine if this activity will affect a site that is listed on the National Register of Historic Places, or a site that may be eligible for listing on the Register. We are also coordinating with the appropriate Tribal entity or the Tribal Historic Preservation Offices for the Shoshone Paiute Tribe, to determine if there are any tribal historic or cultural interests within the project area. 

TRIBAL TREATY RIGHTS and INTERESTS: Federal agencies acknowledge the federal trust responsibility arising from treaties, statues, executive orders and the historical relations between the United States and American Indian Tribes. The federal government has a unique trust relationship with federally recognized American Indian Tribes, including the Shoshone Paiute Tribes. The Corps has a responsibility and obligation to consider and consult on potential effects to Tribal rights, uses and interests. The Corps further recognizes there may be a need for additional and on-going consultation. 

ENDANGERED SPECIES: No listed threatened or endangered species or designated critical habitats are known to exist in the project area. 

ESSENTIAL FISH HABITAT: The Magnuson-Stevens Fishery Conservation and Management Act, as amended by the Sustainable Fisheries Act of 1996, requires all Federal agencies to consult with the National Marine Fisheries Service on all actions or proposed actions, permitted, funded or undertaken by the agency that may adversely affect Essential Fish Habitat (EFH). No EFH species are known to use the project area.

ENVIRONMENTAL IMPACT STATEMENT: Preliminary review indicates the proposed activities will not require preparation of an Environmental Impact Statement. Comments provided will be considered in preparation of an Environmental Assessment. 

EVALUATION: The decision whether to issue a permit will be based on an evaluation of the probable impact, including cumulative impacts, of the proposed activity on the public interest. This decision will reflect the national concern for both protection and utilization of important resources. The benefit which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. 

All factors which may be relevant to the proposal will be considered, including the cumulative effects thereof; among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, consideration of property ownership and in general, the needs and welfare of the people. In addition, our evaluation will include application of the EPA Guidelines (40 CFR 230) as required by Section 404(b)(1) of the Clean Water Act. 

CONSIDERATION OF PUBLIC COMMENTS: The Corps of Engineers is soliciting comments from the general public; Federal, State and local agencies and officials, Tribal entities and other interested parties in order to consider and evaluate the impacts of this proposed activity.

Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. 

To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity.
