Dear Ms. Fox:

This letter is an.official request for the Chatfield Basin Conservation Network (CBCN) to participate
as a special technical advisor for the Chatfield, Colorado Storage Reallocation Feasibility Report and
Environmental Impact Statement (EIS), Advisory input and research data from CBCN were requested by
several representatives of Cooperating Agencies for the Feasibility Report/EIS. Data previously collected
by your organization from within the Chatfield drainage basin that were identified as having special value
include Geographic Information System (GIS) mapping and information pertaining to riparian open space
areas, riparian wildlife habitat, and potential mitigation sites for Preble's meadow jumping mouse habitat.

This letter provides the general expectations for the interactions anticipated to occur between the
U.S. Army Corps of Engineers, Omaha District (Corps) and CBCN (including its contractors) as a special
technical advisor d~ring the,preparation of the Feasibility Report/EIS. The Corps may assign tasks,
, . i.. ~ .' , ~ ; , .
request information and data related to your organization's area of expertise, invite help in identifying and
quantifying significant resources, request assistance in identifying impacts to resources and potential
mitigation options to offset significant impacts, and ask for your participation in other areas, The Corps
may also request early review of documents, including two week reviews of chapters as they are
completed. So that the Corps can focus on completing the Feasibility Report/EIS, it is to be understood
that documents receiving early review are works in progress and are not to be released outside your
organization.

The Corps also requests that you provide a point of contact, and alternate point of contact if desired,
to represent CBCN for actions as a special technical advisor. Ms. Elizabeth Peake will serve as the Corps
contact for all items related, to the National En~iro~mental Policy Act. She may be reached by telephone
at [phone]; by facsimile at [phone]; and by eniail at elizabeth:b~peake@us~ce.army,mil.

"

CBCN is invited, but not required, to attend general Chatfield Reallocation project study meetings,
held approximately once per month and coordinated by the Colorado Water Conservation Board. Your
organization may be requested to participate in one or more technical working groups which are formed
and meet on an as-needed basis, Agendas will be emailed to the point(s) of contact named by CBCN in
response to the request in the previous paragraph.

The Corps anticipates that the successful interactions between our organizations will enhance the
analyses in the EIS and ensure that the scope and content of the EIS will adequately address any concerns
your organization may have about the proposed action. However, it is understood that CBCN's
agreement to serve as aspecial technical advisor will not preclude nor abridge your organization's ability
to independently comment regarding potential effects on the environment of proposed actions and
reasonable alternatives, Feasibility Report/EIS review efforts of CBCN are not reimbursed by the Corps.
