The Colorado Department of Public Health and Environment also reviews eat project with
respect to the anti-degradation provision in state regulations. For the project hich is the
subject of this public notice, the Colorado Department of Public Health and E vironment,
Water Quality Control Division, has preliminarily determined this project will ause only
temporary changes in water quality. The Water Quality Control Division soli 'ts
information which may lead them to conclude that the water quality impacts fr m these
projects may be more than temporary, and therefore, may violate the antidegr ation
provisions of the water quality standazds. For further information regazding ti-degradatio
provision, please contact Mr. Farrow at the Colorado Department of Public H~ alth and
Environment, telephone [phone].
A search of the Colorado Cultural Resource Inventory indicated that there are of any
known cultural resources within the project area. Since the operations take pl ce instream
within the floodplain, the Colorado Historical Society believes the present natu a of the
proposed project area is such that no further impact upon cultural resources wi 1 occur.
However, if previously unidentified archaeological resources are discovered in the course of
the project, work must be interrupted until the resources are properly evaluat in terms of
the National Register of Historic Places eligibility criteria (36 CFR 60.4) in co sultation
with the Corps of Engineers and the State Historic Preservation Office. Mr. J m Green with
the Colorado Historic Society can be contacted at telephone [phone] fo further
assistance.
An activity may not occur in a component of the National Wild and Scenic Ri er System; or
in a river officially designated by Congress as a "study river" for possible incl Sion in the
system, while the river is in an official study status. Coordination with the N final Pazk
Service and U.S. Forest Service has revealed that the Animas River was not f and to be
eligible based on initial studies performed in 1983. Therefore, the Animas Ri er is neither
a component of the National Wild and Scenic River System nor is it in an offs cal study
status.
The Animas River Valley between Durango and the Town of Silverton has bee

Animas River Valley is still currently classified as a potential NNL site due to
