RE: Roaring Fork Resources Application for Mamm Creek Sand & Gravel Pit
Dear Mr. Squires:
Per the request of the City of Rifle, we have erepared Phis letter in response to the public noticing
of the above-mentioned proposed mining activity located just east of Rifle, Colorado along the
south side of the Colorado River. Subsequent to receiving the public notice and formally
reviewing the application at the Clerk and Recorders offce of Garfield County, the City of Rifle
requested and received a copy of the application from Balaz 8 Associates. This provided staff
and City Council an opportunity to review and comment on the application. It is the purpose of
this letter to formally make you aware of the City's concerns regarding this proposed activity.
As this proposed activity lies between Interstate 70 and the Colorado River and lies at the
entrance to the City of Rifle, staff and council have the following concerns to express:
That the application will be thoroughly processed and reviewed as to the activity's
potential impact on a variety of environmental issues. We anticipate the following permits
will be required as a condition prior to any approvals from the Division of Minerals and
Geology:
a. M.L.R.B. mining and reclamation permit.
b. Garfield County special use permit.
c. Garfield County Floodplain special use permit.
d. City of Rifle watershed permit.
e. N.P. D.E.S. permit through the Colorado Department of Public Health and
Environment (C.D.P.H.E.).
f. U.S. Army Corps of Engineers 404 permit.
a C.D.P.H.E. 401 Certification
h. Compliance with Section 7 of the Endangered Species Act
i. Fugitive dust notification.
j. F.A.A. notice and approval relative to waterfowl hazards that may be realized as
a result of activity created lakes and the close proximity to the Garfield County
Aiport.
k. Water augmentation plan for lake evaporation and water consumption.
2. That the floodplain/floodway impacts are thoroughly evaluated. Concern is expressed as
the proposed activity lies within the floodplain and floodway of. the Colorado River.
Various other similar activities in the Colorado River Valley have actually changed the
geologic character of the Colorado River and changed its normal course of flow. This
has created the need for local agencies to expend money and effort to revise and/or
enact additional mitigation measures necessary to protect river crossings and other
development that may be negatively impacted by changes in the geological character of
the Colorado River. The application will need to assure that mitigation efforts are
performed such that periodic flooding of the "developed lakes" (even from ordinary high
