2.0 ELEMENTS ANALYZED

The following describes elements analyzed in this Supplemental Filing including:

• Construction, operation, and maintenance of four Project gages and associated features proposed in Placer County Water Agency’s (PCWA’s) Application for New License (herein, referred to as the Final License Application [FLA]) for the Middle Fork American River Project (MFP or Project) (PCWA 2011);

• Instream flow and reservoir minimum pool conditions provided in the United States Department of Agriculture-Forest Service (USDA-FS) preliminary Section 4(e) conditions (USDA-FS 2011), California Department of Fish and Game (CDFG) Section 10(j) recommendations (CDFG 2011), and United States Department of the Interior (DOI) Section 10(a) recommendations (DOI 2011);

• Additional recreation enhancements (facilities and features) in the Recreation Plan provided in USDA-FS preliminary Section 4(e) conditions and CDFG Section 10(j) recommendations;

• Vegetation and pest management activities described in the revised Vegetation and Integrated Pest Management Plan (VIPMP) (Attachment 1A) agreed upon by the MFP stakeholders in November 2011;

• Road and trail maintenance activities described in the revised Transportation System Management Plan (TSMP) (Attachment 1B) agreed upon by MFP stakeholders in November 2011;

• Project effects on cultural resources with consideration of site-specific management measures and general procedural requirements described in the Draft Final Historic Properties Management Plan (HPMP) (Volume 3) agreed upon by MFP stakeholders in November 2011.

Project facilities and features, and Project recreation facilities and features included in this analysis are listed in Tables 2-1 and 2-2. Tables 2-3 through 2-7 include information related to routine facilities inspections, testing, and maintenance activities at Project facilities and features, Project roads and trails, and Project recreation facilities and features, respectively. The location of Project facilities and features and Project recreation facilities and features are depicted on Maps 2-1a-g and Maps 2-2a-g. Each element analyzed is described in detail below.

2.1 CONSTRUCTION, OPERATION, AND MAINTENANCE OF FOUR NEW PROJECT GAGES

The FLA identified four new gages and associated features to be constructed as part of PCWA’s Proposed Action at the following locations:

• North Fork Long Canyon Creek below Diversion Dam; • South Fork Long Canyon Creek below Diversion Dam; • Middle Fork American River below Interbay Dam; and • North Fork American River above American River Pump Station.


November 2011 2-2

At the time of submittal of the FLA, the precise location of these gages had not been determined. In the FLA, Section 4.1.6.1, PCWA stated that “Project-specific National Environmental Policy Act (NEPA) analysis will be conducted at a later date and all necessary permits and approvals will be obtained prior to implementation of any construction activities”. Following submittal of the FLA, PCWA developed the necessary information to complete environmental analysis on the four new gages under NEPA, including: (1) identification of the specific location of the gages; (2) development of site-specific construction activities; (3) description of future operation and maintenance activities; and (4) identification of biological and cultural resources in the vicinity of the proposed new gages and associated features.

PCWA will be responsible for construction, operation, and maintenance of each new gage and its associated features. Refer to Appendix A – Modified or New Facilities Construction Activities and Concept Designs for detailed information on construction activities and schedule; associated Best Management Practices (BMPs) and avoidance and protection measures (AP) (as applicable); and concept design drawings and/or maps for each new facility. Refer to Table 2-3 for maintenance activities that will occur at each new gage.

Section 3.0 describes potential impacts on environmental and cultural resources from construction, operation, and maintenance of the new gages and associated features. This analysis is supported by supplemental biological and cultural surveys conducted by PCWA in spring and summer 2011 (Attachment 2A; Volume 3).

2.2 RESOURCE AGENCIES PRELIMINARY CONDITIONS AND RECOMMENDATIONS

The following provides details of the resource agencies preliminary conditions and recommendations analyzed in this Supplemental Filing.

2.2.1 Instream Flow and Reservoir Minimum Pool Conditions

Specific resource agencies instream flow and reservoir minimum pool conditions proposed in USDA-FS preliminary Section 4(e) conditions, CDFG Section 10(j) recommendations, and DOI Section 10(a) recommendations include:

USDA-FS Preliminary Section 4(e) Conditions and CDFG Section 10(j) Recommendations

• Condition No. 22 – Minimum Streamflows; • Condition No. 23 – Pulse Flows; • Condition No. 24 – Ramping Rates; • Condition No. 25 – Outages; • Condition No. 39 – Recreation Streamflows in the Middle Fork American River

Below Oxbow Powerhouse; and • Condition No. 37 – Reservoir Minimum Pool Elevations and Reservoir Levels

Recreation Objectives.


November 2011 2-3

DOI Preliminary Section 10(a) Recommendations

• b2. – Minimum Streamflows;

• b3. – Peaking Reach Ramping Rate and Oxbow Powerhouse Operations;

• b4. – Outages; and

• b5. – Recreation Streamflows in the Middle Fork American River below Oxbow Powerhouse.

Section 3.0 describes potential impacts on environmental and cultural resources from implementation of resource agencies instream flow and reservoir minimum pool conditions.

2.2.2 Recreation Plan

The Recreation Plan proposed in USDA-FS preliminary Section 4(e) conditions and CDFG Section 10(j) recommendations includes the following enhancements (facilities and features):

Existing Recreation Trails Added to MFP

• Poppy Trail;

• Hell Hole Reservoir Trail; and

• Middle Fork American River above Ralston Afterbay Trail.

PCWA will be responsible for routine operation and maintenance, and heavy maintenance of these trails.

New Recreation Facilities and Features

• French Meadows Reservoir Trail; and

• Ellicott Bridge Parking Area.

PCWA will be responsible for construction, routine operation and maintenance, and heavy maintenance of these recreation facilities and features.

Replacement of Existing Recreation Features

• French Meadows North Shore Water Supply; and

• French Meadows South Shore Water Supply.

PCWA will be responsible for construction, routine operation and maintenance, and heavy maintenance of these existing water supply lines. The FLA described these facilities as being repaired and maintained under “routine heavy maintenance” activities (i.e., “repair and maintenance of potable water tanks, supply and distribution lines, and


November 2011 2-4

valves and faucets”). In resource agencies preliminary conditions and recommendations, both of the French Meadows water supply systems will undergo more extensive improvements than previously contemplated in the FLA, and therefore are considered construction projects rather than heavy maintenance activities.

Routine operation and maintenance activities and routine heavy maintenance activities at Project recreation facilities and features included under Alternative 1 are identified on Tables 2-6 and 2-7, respectively. Construction activities required to implement the Recreation Plan are provided in Appendix A – Modified or New Facilities Construction Activities and Concept Designs. Appendix A also identifies associated BMPs and AP measures (as applicable), and concept design drawings and/or maps for each new facility.

Section 3.0 describes potential impacts on environmental and cultural resources from construction, operation, and maintenance of the recreation facilities and features included in the Recreation Plan. This analysis is supported by supplemental biological and cultural surveys conducted by PCWA in spring and summer 2011.

2.3 STAKEHOLDER AGREED UPON MANAGEMENT PLANS

In November 2011, PCWA and MFP stakeholders reached consensus on revisions to the VIPMP (Attachment 1A), TSMP (Attachment 1B), and HPMP (Volume 3). It is anticipated that the resource agencies will be filing with FERC these revised stakeholder agreed upon management plans as modified preliminary terms and conditions for the MFP. The attached stakeholder agreed upon VIPMP, TSMP, and HPMP are analyzed in this Supplemental Filing. Each management plan is described below.

2.3.1 Vegetation and Integrated Pest Management Plan

The VIPMP includes: (1) Project facilities and features, Project roads and trails, and Project recreation facilities and features identified in PCWA’s Proposed Action where vegetation and pest management is implemented; and (2) additional recreation facilities and features identified in the Recreation Plan provided in USDA-FS preliminary Section 4(e) conditions and CDFG Section 10(j) recommendations.

The VIPMP describes vegetation management (i.e., trimming by hand or with equipment and use of herbicides, surfactants, and fungicides) and pest management activities (i.e., noxious weed management and rodent control) to be implemented at Project facilities and features, Project roads and trails, and Project recreation facilities and features, as well as measures for the enhancement and/or protection of environmental and cultural resources during implementation of these activities.

Pest management conducted under the VIPMP includes both noxious weed management and rodent control. The noxious weed management program includes manual/chemical treatment of noxious weeds, measures to reduce the introduction or spread of noxious weeds, and implementation of a noxious weed training program. This program will enhance habitat for native plant and wildlife species in the MFP and could


November 2011 2-5

promote establishment of new special-status plant populations through improved habitat conditions by reducing competition with invasive noxious weeds.

Rodent control, which includes both physical control (e.g., snap traps) and rodenticide use (e.g., over-the-counter rodenticides and fumigants), is necessary to protect the structural integrity of dams and prevent rodent infestations in building interiors. The VIPMP includes specific rodenticide application methods to be used to protect water quality and prevent secondary effects on raptors and other scavengers.

The VIPMP also identifies several measures to avoid and protect environmental resources including special-status plant and noxious weed inventory surveys, Water Quality Monitoring for Chemical Treatment Program, Environmental Training Program (ETP), and annual consultation with resource agencies.

Section 3.0 describes potential impacts on environmental and cultural resources from implementation of vegetation and pest management activities in the VIPMP. This analysis is supported by supplemental biological and cultural surveys conducted by PCWA in spring and summer 2011.

2.3.2 Transportation System Management Plan

The TSMP includes: (1) Project roads, Project trails, and Project recreation facility access roads identified in the Proposed Action; and (2) additional Project trails and a Project recreation facility parking area identified in the Recreation Plan provided in USDA-FS preliminary Section 4(e) conditions and CDFG Section 10(j) recommendations.

The TSMP identifies PCWA’s responsibilities over the term of the new license related to the operation and maintenance of: (1) Project roads and trails; and (2) Project recreation facility access roads. Specific commitments and measures identified in the TSMP include funding of land management agency administrative oversight activities, implementation of routine annual and periodic maintenance activities, documenting road and trail conditions, implementation of special road and trail projects, and conducting traffic counts. The TSMP also includes measures for the protection of environmental and cultural resources and consultation with appropriate land management agencies. Measures to protect cultural resources during road and trail maintenance activities are provided in the HPMP.

Section 3.0 describes potential impacts on environmental and cultural resources from implementation of road and trail maintenance activities in the TSMP. This analysis is supported by supplemental biological and cultural surveys conducted by PCWA in spring and summer 2011.

2.3.3 Draft Final Historic Properties Management Plan

The HPMP addresses Project operation, maintenance and construction activities at: (1) Project facilities and features, Project roads and trails, and Project recreation facilities and features identified in PCWA’s Proposed Action; and (2) additional


November 2011 2-6

recreation facilities and features identified in the Recreation Plan provided in USDA-FS preliminary Section 4(e) conditions and CDFG Section 10(j) recommendations.

The HPMP describes measures that PCWA will implement to manage the four properties located within the MFP Area of Potential Effect (APE) that are eligible for the National Register of Historic Places (NRHP). The HPMP also describes: (1) how PCWA will manage Project activities that may affect paleontological resources (although to date, none have been identified in the Project vicinity); and (2) monitoring of cultural resources within the APE over the term of the license. Measures to manage vegetation and pest management activities in the vicinity of potential traditional cultural properties (including traditional gathering areas) are included in the VIPMP.

Section 3.0 describes potential impacts on environmental and cultural resources from implementation of project activities included under Alternative 1. This analysis is supported by supplemental biological and cultural surveys conducted by PCWA in spring and summer 2011.
