Special Status Plant and Animal Species

It is assumed that in all cases, full compliance with Section
7 of the Endangered Species Act (1973) would be completed
before invoking specific actions resulting from RMP
decisions. This requires mandatory consultation and
coordination with the USFWS and clearance of lands
inhabited by these species. It is assumed that inventory
analysis and monitoring would be done for special pIant
and animal species. Clearances for special plant and animal
species would be completed for all proposed management
actions in all alternatives.

Waterpower/Storage

It is assumed that additional waterpower/storage site
withdrawals would continue to be made on sites that meet
the qualifying criteria for waterpower/storage.

Location and evaluation of new waterpower/storage sites
would continue and would be added to the inventory. Land
acquisitions of waterpower/storage sites meeting the criteria
would be completed as needed and subsequent waterpower /
storage site withdrawal would be made where appropriate.

ALTERNATIVES ANALYSIS

The following four sections of this chapter present the four

ENVIRONMENTAL CONSEQUENCES

alternatives, which are Existing Management, Natural
Resource Enhancement, Resource Production Enhancement,
and the Preferred.

Only resources and resource uses with an identified net affect
(after various standard mitigation measures are applied) are
analyzed. A description of this net affect and any determined
cumulative effects are presented in this analysis section.

EXISTING MANAGEMENT
ALTERNATIVE

The following impacts are the unavoidable net effects in
this alternative.

Minerals Management

I

Under this alternative, approximately 617,251 acres (99.5
percent) of the Federal fluid mineral estate would be open
for leasing and 3,620 acres (0.5 percent) would be closed
to leasing. Appendix B identifies proposed lease stipulations
for the resource specific requirements for stipulation waivers,
exceptions, and modifications. Tables 4-6 and 4-7 list this
acreage by leasing categories for oil and gas and geothermal
resources.
