Re: Regional General Permit Number 37 (F51e #200275200)
Dear Ms. Hellige:

In June of 2002, the Corps of Engineers, Sacramento District (Corps) issued the permit described
above to Four Comers Materials (FCM) for work in the Animas River north of Durango. The
project involved the installation of a bank armoring system and the associated diversion of the
active channel away from the work area. The armoring system was designed to protect ayet-to-
be-excavated off-stream pond from any future capture by the Animas River.
According to documents submitted by FCM to the Corps during the application process, the
original schedule intended that installation of the armoring system and excavation of the pond
would occur within a single season. For various reasons, the actual sequence of events has
differed from the original plan. Diversion of the active channel; construction of the armoring;
and seeding of the embankment slope and top occurred during 2003. A portion of the pond was
excavated in the winter of 2005; completion is scheduled for winter and spring of 2006.
Special Condition 3 of the Permit requires that "A monitoring report... shall be submitted to the
Durango Regulatory Office each year by December 1, following completion of the project and
for a minimum of three years after irrigation is discontinued.. °' The first monitoring report has
yet to be submitted.
A chronology of the work to date is enclosed with this letter, along with photographs of the site
at various stages. Excavation activities in 2005 substantially disturbed the vegetative cover that
developed after the 2003 seeding and mulching effort. The entire area affected by excavation of
the pond will be seeded and mulched in 2006, as described in the Reclamation permit issued by
the Colorado Division of Minerals and Geology. FCM proposes to re-seed any portions of the
embankment covered by GP37 #200275200 concurrent with these reclamation activities. In
addition, willow stakes will be planted between the concrete blocks as required.
