1. INTRODUCTION
On December 14, 2012, Alaska Energy Authority (AEA) filed with the Federal Energy
Regulatory Commission (FERC or Commission) its Revised Study Plan (RSP) for the Susitna-
Watana Hydroelectric Project No. 14241 (Project), which included 58 individual study plans
(AEA 2012). Section 10.12 of the RSP described the Small Mammal Species Composition and
Habitat Use Study (Small Mammal Study). The study will be an office-based analysis to review
and synthesize available information on the occurrence and relative abundance of small
mammals in the Project area. The study will describe the species of small mammals known to
occur in the Project area and their patterns of habitat use. RSP Section 10.12 provided goals,
objectives, and proposed methods for data collection regarding small mammals.
On February 1, 2013, FERC staff issued its study determination (February 1 SPD) for 44 of the
58 studies, approving 31 studies as filed and 13 with modifications. RSP Section 10.12 was one
of the 31 studies approved with no modifications.
Following the first study season, FERC’s regulations for the Integrated Licensing Process (ILP)
require AEA to “prepare and file with the Commission an initial study report describing its
overall progress in implementing the study plan and schedule and the data collected, including an
explanation of any variance from the study plan and schedule.” (18 CFR 5.15(c)(1)) This Initial
Study Report (ISR) on the Small Mammal Study has been prepared in accordance with FERC’s
ILP regulations and details AEA’s status in implementing the study, as set forth in the FERC-
approved RSP (referred to herein as the “Study Plan”).
2. STUDY OBJECTIVES
The goal of the Small Mammal Study is to synthesize baseline data on small mammals in the
Project area to enable habitat-based assessments of the impacts expected to occur from
development of the Project.
The Small Mammal Study has two specific objectives, as established in RSP Section 10.12.1:
• Describe the species composition and relative abundance of small mammals in the
Project area.
• Describe the habitat associations of small mammals within the Project area
3. STUDY AREA
As established by RSP Section 10.12.3, the study area consists of the entire Project area (Figure
3-1). Existing data on the abundance and habitat associations of small mammals from the
original study for the Alaska Power Authority (APA) Susitna Hydroelectric Project (Kessel et al.
1982) will be supplemented with more recent data from other regional studies and will be
applied to the wildlife habitat types mapped throughout the reservoir inundation zone, associated
facilities areas, and the access road and power transmission corridors.

4. METHODS AND VARIANCES IN 2013
This Study Plan was not implemented in 2013, as was proposed in RSP Sections 10.12.6 and
10.12.10. Deferring the entire study to the next study season is a variance. AEA will meet Study
Plan objectives by completing the study in the next study season. Deferral of this study until the
next study season also will benefit from having contemporaneous data from the Vegetation and
Wildlife Habitat Mapping Study in the Upper and Middle Susitna Basin (Study 11.5)
(“Vegetation Mapping Study”) available at the time this study is completed.
5. RESULTS
There are no results to report for this study.
6. DISCUSSION
As described in RSP Section 10.12.7, this study will use information from the Vegetation
Mapping Study. Because the Vegetation Mapping Study is ongoing and not yet complete, this
study has been deferred until the next study season.
In addition, this study is one of several studies that will be used in the habitat rankings prepared
by the Evaluation of Wildlife Habitat Use (Study 10.19). The other studies (including the
Vegetation Mapping Study (Study 11.5) and Terrestrial Furbearer Abundance and Habitat Use
(Study 10.10) are ongoing and are unaffected by the deferral of this study in 2013.
