CHAPTER 1. INTRODUCTION

BACKGROUND

The Lower Clear Creek Floodway Rehabilitation Project (LCCFRP) is a multi-phased ecosystem restoration project that was designed to restore natural stream channel and floodplain processes in areas that were severely impacted by gold mining, aggregate mining, and the effects of Whiskeytown Dam. The LCCFRP is located west of Redding, in Shasta County, California (Figure 1) and is part of a larger comprehensive watershed restoration program that includes spawning gravel augmentation, in-stream flow management, dam removal, erosion control, fuels reduction, and invasive weed management projects. Phases 1, 2A, 2B and 3A of the LCCFRP were completed between 1998 and 2002. Two phases remain to be completed (Phases 3B and 3C).

PURPOSE AND NEED

The Bureau of Land Management (BLM) has identified a need to analyze minor changes to the project description and impact avoidance and mitigation measures outlined in the previously approved (December 1999) Decision Record and Finding of No Significant Impact (FONSI).

The FONSI was based on a joint California Environmental Quality Act (CEQA) Initial Study/National Environmental Policy Act (NEPA) Environmental Assessment (IS/EA) (Reclamation et al. 1999) for the LCCFRP. Since the approval of the LCCFRP – Phase 2B Modification Decision Record and FONSI, dated July 18, 2001 (RE-01-22), the Lower Clear Creek Restoration Team (Restoration Team) has identified several modifications to the original IS/EA that are necessary to better accomplish the purpose and need of the LCCFRP, which is to rehabilitate ecological function and fishery habitats within this degraded section of lower Clear Creek.

1) The Restoration Team recommended that Phase 3B of the LCCFRP be modified to incorporate an expansion of the original project area upstream of the “Gravel Mined Site” as a borrow site (Figure 2). The minor design modification for Phase 3B involves the expansion of the project boundary to include additional floodplain creation sites adjacent to the original project boundary. These changes are being proposed to accommodate the requirements of the California Regional Water Quality Control Board (RWQCB) to use fill material from within the floodplain, as opposed to unsorted and/or unwashed dredge tailings due to the concern with potential mercury contamination.

2) The Restoration Team recommended modifying several of the impact avoidance and mitigation measures that were originally incorporated into the LCCFRP to reduce potential impacts to soils, water quality and anadromous salmonids. The purpose of the modifications to the measures is to accommodate the construction time constraints that exist for Phase 3B of the project, update the measures to reflect current environmental standards and increase the effectiveness of the measures.

3) The Restoration Team recommended modifying an impact avoidance and mitigation measure that was originally incorporated into the LCCFRP to reduce potential impacts to the valley elderberry longhorn beetle (VELB) (Desmocerus californicus dimorphus). The purpose of the modification to the measure is to reflect the most current conservation guidelines established by the U.S. Fish and Wildlife Service (USFWS 1999).

4) The Restoration Team recommended modifying and adding impact avoidance and mitigation measures to reduce potential impacts to the foothill yellow-legged frog (Rana boylii), the little willow flycatcher (Empidonax trailii brewsteri), and other neotropical migratory songbirds. The purpose of the modification and addition of these measures is to accommodate the construction time constraints that exist for Phase 3B of the LCCFRP, clarify the original intent of the measures and reduce potential impacts to the foothill yellow-legged frog, which was not thought to be present at the time that the prior NEPA documents were prepared.

LAND USE PLAN CONFORMANCE AND OTHER REGULATORY COMPLIANCE

The proposed action is consistent with the objectives stated on page 44 of the Redding Resource Management Plan (RMP), dated June 1993 (BLM 1993). The proposed expansion of the LCCFRP project area is located on public lands administered by the BLM within the general area of potential environmental impact analyzed in the 1999 Decision Record and FONSI for the

LCCFRP.

CHAPTER 2. DESCRIPTION OF THE PROPOSED ACTION AND

ALTERNATIVES

PROPOSED ACTION

Expansion of the Phase 3B Project Area BLM and the Restoration Team are proposing an extension of the Phase 3B project area upstream of the Gravel Mined Site (Figure 2). The extension of the Phase 3B project area (Phase 3B Borrow Area), would be used to extract floodplain deposits to construct the Phase 3B floodplains and realign the creek channel. The LCCFRP originally encompassed a total of 325 acres at four sites. The proposed action would increase the project area to a total of 342 acres at four sites by adding 17 acres to the upstream portion of the Gravel Mined Site. The Phase 3B Borrow Area includes the north and south sides of lower Clear Creek, an estimated 17.44 acres,

6.04 and 11.40, respectively. The estimated amount of material to be removed from the Phase 3B Borrow Area is 106,900 cubic yards (24,300 north bank and 82,600 south bank).

Approximately 75 percent of the disturbed area would be revegetated with riparian vegetation.

The selection of native plant species would occur during revegetation design process, after Phase 3B construction is completed and a site assessment is conducted.

Modification and Addition of Mitigation Measures BLM and the Restoration Team propose to modify, and add to, impact avoidance and mitigation measures identified in the original IS/EA. Under the proposed action, the following modified and additional measures would be incorporated to reduce the potential impacts of the LCCFRP.

The LCCFRP originally incorporated impact avoidance and mitigation measures to reduce potential impacts to soils, water quality, and several anadromous fish species including Central Valley fall-run, late fall-run, spring-run Chinook salmon (Oncorhynchus tshawytscha), and Central Valley steelhead (Oncorhynchus mykiss). The proposed action modifies several of the measures to accommodate the construction time constraints that exist for Phase 3B of the LCCFRP, reflect current environmental standards and increase the effectiveness of the measures, while continuing to reduce potential impacts of the LCCFRP.

Monitoring of water turbidity and settleable materials shall be conducted as specified in the Clean Water Act Section 401 Certification conditions. Should water turbidity levels or settleable materials be found to exceed those levels stated in the Clean Water Act Section 401 Certification conditions, construction activities shall cease until turbidity and settleable materials decrease to acceptable levels.

When work in a flowing stream is unavoidable, the entire streamflow shall be gradually diverted around the work area by a barrier, temporary culvert and/or a new channel capable of permitting upstream and downstream fish movement. Construction of the barrier and/or new channel shall proceed in a manner that minimizes sediment discharges and facilitates both fish rescue operations and fish escape from the work area. A reduction of 1/10 of 1 foot of stream gauge height per hour will be used for dewatering the existing channel. For dewatering bypass channels, the rate will be increased due to the simple channel geometry and the lack of side channels, or backwater habitat. The bypass channel dewatering rate will be an initial drop of ½ of 1 foot per hour until the last ½ foot where the rate will be 1/10 of 1 foot per hour. For all dewatering operations, a monitoring fisheries biologist will determine if, and when, fish rescue operations are needed.

Uncrushed cleaned gravels ( -inch to 5-inch) shall be used to construct necessary stream crossings. Following construction, these gravels shall be leveled and left instream to improve spawning habitat for anadromous salmonids.

Instream construction activities shall be limited to the period from June 1 to October 31 of each year with the exception of stream crossings. Limiting construction activities to this period will reduce potential adverse impacts to spawning adults and incubating eggs, fry, and juveniles. Installation and removal of stream crossings shall be limited to the period between June 1 and November 15. All but one of the stream crossings will be removed prior to October 31.

The LCCFRP originally incorporated an impact avoidance and mitigation measure to reduce potential impacts to the VELB, a species listed as Threatened by the USFWS. The proposed action modifies the measure to reflect the most current conservation guidelines established by the USFWS. The modification of the impact avoidance and mitigation measure would continue to reduce potential impacts to the valley elderberry longhorn beetle.

To reduce potential impacts to the VELB, the project will incorporate, as applicable, the USFWS established mitigation guidelines for the VELB dated July 9, 1999.

The LCCFRP originally incorporated impact avoidance and mitigation measures to reduce potential impacts to several neotropical migratory bird species. In an effort to minimize disturbance and reduce impacts to neotropical migratory birds, protected under the Migratory Bird Treaty Act, and little willow flycatcher and foothill yellow-legged frog, species covered by BLM sensitive species policy (BLM Manual 6840), mitigation measures have been developed.

Mitigation measures can include any of the following:

Avoiding construction activities within the immediate area until August 1 or until after fledging and dispersal of young has occurred.

Remove potential nesting habitat prior to nesting (April 15).

Implement the project on a phased schedule and incorporate key save areas for nesting and fledging.

Revegetation designs will incorporate native plants that are important to native nesting songbird species, and will be monitored and maintained for three years to ensure they meet the established long-term success criteria.

Although unlikely, if nesting little willow flycatchers have been identified in the project area, construction activities within 0.25 miles of nesting areas will be delayed until after fledging and dispersal of young has occurred.

Surveys for foothill yellow-legged frogs shall be conducted prior to the onset of construction activities. Foothill yellow-legged frogs located will be captured and relocated to suitable habitat areas outside of the construction area.

NO-ACTION ALTERNATIVE

The “no-action” alternative is defined as not implementing any aspect of the proposed action alternative(s). The no-action alternative serves as a baseline or reference point for evaluating the environmental effects of the action alternatives. The no-action alternative is not a “static” alternative. Implicit in it, is the continuation of the environmental conditions and trends that currently exist, or are occurring, within the project area.

Under this alternative, the expansion and floodplain modification of the Gravel Mined Site to include the Phase 3B Borrow Area would not occur. Materials from the borrow area would not be used for the Phase 3B fill sites. In addition, under this alternative, no impact avoidance and mitigation measures would be modified or added to the LCCFRP.

CHAPTER 3. AFFECTED ENVIRONMENT

It has been determined through scoping and resource specialist review that the following resources will not be affected by the action and accordingly these resources will not be addressed in the affected environment: Air Quality, Areas of Critical Environmental Concern (ACECs), Cultural Resources, Native American Concerns, Farmlands, Minerals, Threatened and Endangered Plant Species, Solid and Hazardous Wastes, Wild and Scenic Rivers, Wilderness, Environmental Justice, Visual Resource Management and the Northwest Forest Plan Aquatic Conservation Strategy. Only those elements where there has been an identified resource concern or an attributable effect from the action will be further addressed.

GEOLOGY AND SOILS

Refer to the original IS/EA for a description of the affected environment.

SURFACE WATER AND HYDROLOGY

Refer to the original IS/EA for a description of the affected environment.

WETLAND / RIPARIAN RESOURCES

North State Resources, Inc. (NSR) conducted a delineation of jurisdictional waters of the U.S.

(wetland delineation) within the Gravel Mined Site, Reading Bar and Former Shooting Gallery borrow sites, and the Old Mill wetland creation site (NSR 1999). A subsequent wetland delineation was conducted in the expanded Phase 3B project area (Souza Environmental Solutions, Inc. et al. 2006). As a result of the subsequent wetland delineation, an additional

16.89 acres of potentially jurisdictional waters of the U.S. were mapped including 7.63 acres of wetlands (riparian-freshwater emergent wetland complex) along with 9.26 acres of other waters of the U.S. The other waters included 0.08 acres of intermittent creek, 0.01 acres of ephemeral creek and 9.17 acres of perennial creek (Clear Creek).

BIOLOGICAL RESOURCES

Although identified in the CEQA addendum (WSRCD 2007) and the Action Specific Implementation Plan (ASIP) (WSRCD et al. 2007) for Phase 3B of the LCCFRP, those species designated by the State of California as either Fully Protected or Species of Special Concern, or by the California Native Plant Society (CNPS) as Category List 2, will not be considered in this document.

Wildlife and Fish Multiple special-status wildlife species potentially occur in the project area. These species include the little willow flycatcher and the foothill yellow-legged frog, two sensitive species covered by the BLM Manual 6840, neotropical migratory birds protected by the Migratory Bird Treaty Act of 1918, and the VELB, a species listed as federally threatened.

Special-status fishery species include the Sacramento River winter-run Chinook salmon, listed as state and federally Endangered, the Central Valley fall-/late fall-run Chinook salmon, designated as a Species of Concern by the National Marine Fisheries Service (NMFS), the Central Valley spring-run Chinook salmon, listed as state and federally Threatened, and the Central Valley steelhead, listed as federally Threatened.

Refer to the original IS/EA for a description of the affected environment for these fish and wildlife species.

DISCUSSION OF ENVIRONMENTAL IMPACTS

Only substantive site-specific environmental changes that would result from implementing the proposed action or alternatives are discussed in this section.

PROPOSED ACTION

GEOLOGY AND SOILS

The modification of the impact avoidance and mitigation measures would not significantly impact geology and soils. One measure is being modified to reflect current RWQCB standards.

Implementation of the modified measures, combined with the original IS/EA measures that were incorporated into the LCCFRP, would continue to reduce potential impacts to soils and geology.

SURFACE WATER AND HYDROLOGY

The modification of the impact avoidance and mitigation measures would not significantly impact water quality. One measure is being modified to reflect current RWQCB standards, and one measure is being modified to specify a dewatering rate. Implementation of the modified measures, combined with the original IS/EA measures that were incorporated into the LCCFRP and the conditions specified in the Clean Water Act Section 401 Certification, would continue to reduce potential impacts to water quality.

WETLAND / RIPARIAN RESOURCES

Under the proposed action, additional wetlands and other waters of the U.S. that are present within the Phase 3B borrow area would be impacted. In addition, wetlands would be created through restoration of the area (see Table 3A and Figures 3A and 3B). A total of 2.37 acres of additional impact to riparian/freshwater emergent wetland would occur as well as an additional

0.76 acres of impact to perennial creek. A total of 13.08 additional acres of riparian wetland are estimated to occur as a result of the creation of functional floodplains and revegetation activities.

Overall, implementation of the proposed action would result in a 14.93-acre increase in the net gain of waters of the U.S. from 81.55 acres to 96.48 acres, including a 10.71-acre increase in the net gain of wetlands from 79.39 acres to 90.10 acres for the entire LCCFRP.

The net environmental effect of the proposed action, resulting from the expansion of the project boundary, is beneficial as it would result in an increase in the net gain of waters of the U.S., including an increase in the net gain of wetlands.

BIOLOGICAL RESOURCES

Wildlife and Fish The guidelines for the VELB are designed to ensure no effect from proposed actions.

Incorporating, as applicable, the 1999 standards will ensure no effect to the VELB or its host plants.

Potential habitat for special-status species and neotropical birds may be removed and modified during the proposed action. However, this loss or modification would be negligible due to the incorporation of mitigation measures, the modification of the impact avoidance measures, the large amounts of suitable habitat to be retained on BLM land nearby and the purpose of the activity. Due to the continuity of habitat adjacent to the project area and the purpose of the action, it is anticipated that project impacts will be minimal and will consist of a short-term avoidance of the area by wildlife and fishery species while work occurs. This temporary disturbance does not constitute impacts that affect the ecologically sustainability of nesting neotropical migratory birds, listed fish species, little willow flycatcher, foothill yellow-legged frog, or other wildlife and fishery species.

NO-ACTION ALTERNATIVE

GEOLOGY AND SOILS

No impacts to geology and soils would occur under the no-action alternative. The current impact avoidance and mitigation measures would remain unchanged.

SURFACE WATER AND HYDROLOGY

No impacts to surface water and hydrology would occur under the no-action alternative. The current impact avoidance and mitigation measures would remain unchanged.

WETLAND / RIPARIAN RESOURCES

No impacts to wetlands or waters of the U.S. would occur under the no-action alternative. The LCCFRP project boundary would not be expanded.

BIOLOGICAL RESOURCES

Wildlife and Fish No impacts to the VELB would occur under the no-action alternative. The project would not comply with 1999 USFWS Conservation Guidelines, and the 1996 Conservation Guidelines (USFWS 1996) would be used.

No impacts to migratory birds would occur under the no-action alternative. The current impact avoidance and mitigation measures would remain unchanged. Under this alternative, Phase 3B of the LCCFRP would have to be implemented over a two-season period due to the time constraints of the current impact avoidance and mitigation. This would significantly increase the cost of implementing Phase 3B, which could potentially make the project infeasible.

No impacts to the willow flycatcher would occur under the no-action alternative. The current impact avoidance and mitigation measures would remain unchanged.

Potential impacts to foothill yellow-legged frog populations could occur, if present within the project area under the no-action alternative. Surveys for foothill yellow-legged frog prior to the start of construction would not occur.

No impacts to anadromous salmonids would occur under the no-action alternative. The current impact avoidance and mitigation measures would remain unchanged. Under this alternative, Phase 3B of the LCCFRP would likely need to be implemented over a two-season period due to the time constraints of the current impact avoidance and mitigation. This would significantly increase the cost of implementing Phase 3B, which could potentially make the project infeasible.

CUMULATIVE IMPACTS

Refer to the original IS/EA for a description of the cumulative impacts of the LCCFRP. While the proposed action would slightly increase the project area, any cumulative impact of this action would be insignificant.

Finding of No Significant Impact and

Decision Record for Environmental Assessment Number RE-2007-44

UNITED STATES DEPARTMENT OF THE INTERIOR

Bureau of Land Management Redding Field Office 355 Hemsted Drive

APRIL, 2007

DECISION: It is my decision to approve the proposed action, i.e. to expand the Lower Clear Creek Floodway Rehabilitation Project boundary at the Gravel Mined Site and modify and add several impact avoidance and mitigation measures, as described in the attached Environmental Assessment (EA) number CA-360-RE-2007-44. Compliance with any mitigation measures and monitoring plan identified in the EA are hereby required and are incorporated into this decision record as stipulations by reference.

Also, pursuant to the Protocol Agreement (2004) between BLM California and the State Historic Preservation Officer, I affirm that all necessary steps have been taken to identify, record and determine effects on cultural properties by an approved staff specialist and is in accordance with all standards and guidelines as outlined in the Protocol Agreement of 2004. Therefore, it is my decision to approve the proposed action described in the attached Environmental Assessment CA-360-RE-2007-44.

FINDING OF NO SIGNIFICANT IMPACT: Environmental impacts associated with the proposed action have been assessed. Based on the analysis provided in the attached EA, I conclude that the approved action is not a major federal action and will result in no significant impacts to the human environment. Preparation of an Environmental Impact Statement to further analyze possible impacts is not required pursuant to Section 102(2)(c) of the National Environmental Policy Act of 1969.

RATIONALE: Based on the analysis documented in the aforementioned EA which has been reviewed by an interdisciplinary team, I conclude that the approved action as stipulated will not result in any unnecessary or undue degradation of the Federal lands. The approved action is in conformance with the approved land use plan. The reasons for this finding are:

The proposed action is a minor modification of the December 1999 “Decision Record and Finding of No Significant Impact for the Lower Clear Creek Floodway Rehabilitation Project” and the July 2001 “Finding of No Significant Impact and Decision Record: Lower Clear Creek Floodway Rehabilitation Project – Phase 2B Modification” which will result in the creation of 10.71 additional acres of wetlands.

The modification and addition of impact avoidance and mitigation measures will facilitate the timely implementation of Phase 3B of the Lower Clear Creek Floodway Rehabilitation Project while continuing to reduce potential impacts to listed and special-status species.

No historic properties deemed eligible for inclusion in the National Register of Historic Places or traditional cultural properties are located within the project area.
