Sufficient mitigation will be formulated to ensure that either the recommended plan or
the NED plan will not have more than negligible adverse impacts on fish and wildlife
resources, An incremental cost analysis will be performed to display variation in costs,
and to identify and describe the least cost mitigation plan, excluding conservation
measures that are formulated for conserving any impacted federally listed endangered
and threatened species. An abbreviated HEP analysis, or equivalent will be performed
for mitigation measures, excluding conservation measures that are formulated for
conserving any impacted federally listed endangered and threatened species. A
mitigation monitoring program will also be developed,

A Draft ENFeasibility Report will be completed, circulated to the public and agencies,
and responses will be prepared for public comments received from circulation of the
Draft Feasibility Report/EA, The biologists will attend the public meetings, Appropriate
changes/revisions will be made in the text to address substantive comments. A FaNS I
will be prepared if it is determined that no significant impacts are anticipated,

6,0 Habitat / Species Survevs

Wildlife, fisheries, and habitat surveys may be needed to provide baseline data on
existing project area conditions, This baseline data is necessary for subsequent impact
assessments that will predict changes to existing conditions that could result from the
various alternatives under future with-project conditions, These studies would be used,
if necessary, to make determinations on how construction activities and habitat changes
would affect endangered and threatened species are made, The exact composition and
extent of environmental surveys is a function of the range of alternative plans and the
availability of data that must be evaluated in detail as part of plan formulation, The
estimated cost of environmental surveys presented in the PMP identifies the probable
upper limit of costs, Individual studies would primarily include habitat surveys where
species of concern may be found, and/or surveys for wetland delineation where project
footprint impacts or habitat enhancemenUrestoration may occur.

The biologist will prepare the scope of work and government cost estimate for the
surveys to be contracted, will negotiate the contract, and will oversee the completion of
the work.

Modified Scope of Work to Define Phase 1
Greeley, Colorado
Updated April 2005

The following tasks listed below reflect the initial three steps of the planning process, In
order to achieve project compliance with all applicable environmental laws and
regulations, and completeness in the preparation of a draft and final integrated
NEPNfeasibility report, all six steps of the planning process must be accomplished prior
to report finalization, as well as any specific compliance requirements, Only general
wildlife, fisheries, and habitat surveys will be conducted with this modified scope of
work, Special detailed surveys of affected wetlands and any affected species of
concern will become necessary for subsequent impact assessment and compliance
requirements,
