Dear Reader: 

We are pleased to announce after several years of collaborative effort, the Record of Decision (ROD) and 

Approved Resource Management Plan (RMP) for Clear Creek Management Area are complete. This 

document will provide guidance for the management of approximately 63,000 acres of public lands in 

southern San Benito and western Fresno counties. 

The attached ROD and RMP have been prepared in accordance with the Federal Land Policy 

Management Act and the National Environmental Policy Act. The ROD links final land use plan 

decisions to the proposed decisions and analysis presented in the CCMA Proposed RMP/Final 

Environmental Impact Statement (FEIS) that was released on April 5, 2013, and subject to a 30-day 

protest period that ended on May 6, 2013. Twenty-one protest letters were received. The protests were 

reviewed by the BLM Assistant Director, Renewable Resources and Planning, in Washington, D.C. After 

careful consideration of all points raised in the protests, the Assistant Director concluded the responsible 

planning team and decision makers followed all applicable laws, regulations, policies, and pertinent 

resource considerations in developing the CCMA Proposed Plan and the FEIS. Adjustments and points of 

clarification incorporated into the RMP in response to issues raised in the protest process and final BLM 

review are discussed in the ROD under Section II.A.9 titled Changes from the Final EIS to the ROD. The 

protest review did not result in any significant changes to the Proposed Action analyzed in the Final EIS. 

The ROD serves as the final decision for the land use planning decisions, described in the attached RMP. 

This ROD also describes a set of implementation decisions (listed in Section II.B). An appeal opportunity 

for these decisions is being provided at this time. The process is described in the ROD and at 43 CFR Part 

4, Subpart E. The appeal period will close 30 days from the date the Notice of Availability of the 

ROD/Approved RMP appears in the Federal Register. 

Now that the ROD has been signed, we look forward to your participation as we implement the plan. If 

you would like more information, please contact the Hollister Field Office, 20 Hamilton Ct., Hollister, 

CA 95023, or by telephone at (831) 630-5000.

Abstract: The Record of Decision and Approved Resource Management Plan for Clear Creek 

Management Area is a project of BLM California that supports the agency’s mission to sustain the health, 

diversity, and productivity of the public lands for current and future generation. The Approved RMP was 

prepared under the authority and regulations implementing the Federal Land Policy and Management Act 

of 1976 (43 Code of Federal Regulations 1600). It includes broad land use plan decisions that provide the 

overall direction for managing resources and resource uses in the Clear Creek Management Area. Land 

use decisions are expressed as goals and objectives (desired outcomes), allowable uses, and management 

actions anticipated to achieve desired outcomes. Land use decisions identified in the Approved RMP are 

final and become effective upon the California State Director’s signing of the ROD. The Approved RMP 

also includes implementation-level decisions; future implementation of these decisions may require 

additional steps and analysis under the National Environmental Policy Act prior to implementation. 

The Planning Area includes a portion of southern San Benito County and a portion of western Fresno 

County. BLM public lands account for more than 63,000 of the 75,000-acre management area. BLM also 

administers subsurface minerals on approximately 3,500 acres of “split estate” (areas where BLM 

administers Federal subsurface minerals but the surface is owned by a non-Federal entity). The lands 

managed by the Hollister Field Office include a variety of settings and landforms, including the southern 

Diablo Mountain Range, Hernandez Valley, and three major watersheds. The Pajaro watershed drains into 

the Pacific Ocean; the Arroyo Pasajero and Silver Creek watersheds drain into the San Joaquin Valley. 

The decisions outlined in this document will enable to BLM to manage and protect resources on public 

lands within the Clear Creek Management Area to achieve desired future conditions and management 

objectives. Planning decisions in this document do not apply to state-, county- or privately-owned lands 

or other federal lands not managed by BLM.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

I.	 Record of Decision 

A. Summary 

Since 1984, approximately 31,000 acres of serpentine soils high in asbestos fibers within the Clear Creek 

Management Area (CCMA) have been designated as the Clear Creek Serpentine Area of Critical 

Environmental Concern (ACEC) to protect public health and safety. The U.S. Environmental Protection 

Agency (EPA) released the CCMA Asbestos Exposure and Human Health Risk Assessment on May 1, 

2008. The results showed that visiting CCMA more than one day per year can put adults and children 

above EPA’s acceptable risk range for exposure to carcinogens and increased excess lifetime cancer risk 

from many typical CCMA recreational activities. 

This Record of Decision (ROD) for the CCMA Resource Management Plan (RMP) identifies sustainable 

multiple use management goals, intermediate objectives, and actions and options for meeting those 

objectives on lands administered by the United States Bureau of Land Management (BLM) Hollister 

Field Office in San Benito County, California. In general, this ROD and the CCMA RMP establish the 

following: 

1.	 Areas for limited, restricted or exclusive use; and special designations; 

2.	 Allowable resource uses and related levels of production or use; 

3.	 Resource condition goals and objectives; 

4.	 Program constraints and general management practices needed to achieve the above items; 

5.	 Need for an area to be covered by more detailed and specific activity level plans; 

6.	 Support actions, including resource protection and public health and safety measures, access 

development, realty actions, etc. as necessary to achieve the above; 

7.	 General implementation sequences, where carrying out a planned action is dependent upon prior 

accomplishment of another planned action; and 

8.	 Intervals and standards for monitoring and evaluating the plan to determine the effectiveness of 

the plan and the need for amendment or revision. 

This ROD/RMP also details implementation level decisions to address resource management issues on 

CCMA public lands. The rationale for these decisions is based on the environmental review and analysis 

conducted in the BLM’s 2013 CCMA Proposed Resource Management Plan (PRMP) and Final 

Environmental Impact Statement (FEIS). 

B. Decision 

It is the decision of the BLM to approve the CCMA RMP, as described in Chapter II. This decision 

reflects the Proposed Action, as outlined in the CCMA PRMP and FEIS (BLM 2013), with minor 

changes from the FEIS to the ROD that are described in Chapter II of this ROD. 

This decision was developed under the regulations implementing the Federal Land Policy and 

Management Act (FLPMA) in accordance with BLM planning regulations (43 CFR 1600). An 

environmental impact statement was prepared in compliance with the National Environmental Policy Act 

(NEPA) of 1969 to consider this decision. This decision considers public comments; best available 

scientific and technical information; and results of consultations with federal and state agencies, local 

governments, Native American tribal governments, a variety of non-governmental organizations, and 

numerous individuals.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

Specific management decisions and guidance for CCMA public lands administered by the BLM’s 

Hollister Field Office are presented in the RMP attached to this ROD. All decisions covered by the ROD 

are either land use planning decisions that were protestable during the April 5, 2013 to May 6, 2013 

protest period in accordance with the land use planning regulations (43 CFR Part 1610), or 

implementation decisions that may be appealed in accordance with Department of the Interior regulations 

at 43 CFR Part 4. Chapter II of this ROD/RMP identifies the implementation decisions that are subject to 

appeal at this time. 

C. Range of Alternatives 

The CCMA PRMP and FEIS (2013) analyzed the RMP and seven alternatives. BLM developed these 

alternatives on the basis of, and in response to substantive public input on the existing environment, 

existing uses, desired future uses, and desired environmental conditions of the CCMA. 

The range of alternatives for the CCMA PRMP/FEIS included multiple public use scenarios in the 

Serpentine ACEC: five of which entail Motorized access (Alternatives A, B, C, D, and E), one Nonmotorized access alternative (Alt. F), and one alternative that considers closure of the Serpentine ACEC 

to all forms of public entry (Alt. G). The anticipated effects and the need to implement proposed 

management actions or mitigation measures would vary depending on the public use scenarios associated 

with each alternative. 

Alternative G is the environmentally preferable alternative because it would cause the least damage to the 

biological and physical environment and best protects, preserves, and enhances historic, cultural, and 

natural resources. 

D. Management Considerations 

The CCMA RMP details allowable uses, resources protection measures, and management tools that the 

BLM will implement in order to protect human health and safety, natural and cultural resources, and 

support recreation opportunities. The selected management approach to recreation and travel management 

in CCMA will allow limited opportunities for visitor use within the Serpentine ACEC. It will provide 

alternate routes for access to public lands surrounding the ACEC that don’t require the public to drive 

through the ACEC. The RMP will also allow BLM to support additional recreation opportunities in the 

surrounding management zones. Limits on annual visitor use days will allow the public to experience the 

scenic, biological, cultural and geologic features of the Serpentine ACEC within EPA’s acceptable risk 

range for exposure to asbestos, and with less BLM infrastructure and support needs. The RMP will also 

provide for improving habitat for endangered species, improved riparian habitat, and an opportunity to 

reduce soil loss and erosion in areas that are contributing to water quality issues in Clear Creek and the 

San Benito River. 

Pursuant to the NEPA, the CCMA RMP meets the purpose and need (described in Chapter II of this 

ROD/RMP); is viable and reasonable; and provides a mix of resource protection, management use, and 

development that is responsive to issues identified in scoping; and meets the established planning criteria, 

federal laws and regulations, and BLM’s land use planning policies.

Record of Decision Resource Management Plan
 

E. Mitigation and Monitoring 

Adopted mitigation measures represent all practicable means to avoid or minimize environmental harm 

from the approved decisions. All mitigation measures from Chapter II and Appendix V of this ROD/RMP 

incorporates a monitoring program to ensure that implementation of the decisions achieves BLM goals 

and objectives for natural and cultural resources on public lands. Monitoring is an essential component of 

natural resource management because it provides information on changes in resource use, condition, 

processes, and trends. Monitoring also provides information on the effectiveness of management 

activities and strategies. Implementation of the decision contained herein will be monitored to ensure that 

management actions follow prescribed management direction (implementation monitoring), meet desired 

objectives (effectiveness monitoring), and are based on accurate assumptions (validation monitoring). 

F. Public Involvement 

1. Public Scoping 

The public scoping period for the CCMA RMP/EIS began September 6, 2007, with the publication of the 

“Notice of Intent To Prepare a Resource Management Plan for the Clear Creek Management Area, 

California, and Associated Environmental Impact Statement” in the Federal Register (Volume 72, 

Number 172). In conjunction with the NOI, BLM issued a news release on September 6, 2007 to 

announce three public scoping workshops. 

Upon release of the EPA’s Asbestos Exposure and Health Risk Assessment for CCMA (2008), BLM 

issued a Temporary Closure order issued on May 1, 2008 that closed the entire 31,000 acre Serpentine 

ACEC to all public use and entry. The temporary closure and results of the EPA asbestos exposure and 

risk assessment quickly polarized interested parties and remained controversial throughout the entire 

CCMA resource management planning process. 

To foster additional public participation and cooperation, BLM issued another news release on May 1, 

2008 to announce three additional public scoping meetings that were held in Hollister, San Jose, and 

Santa Clara, California. The Santa Clara meeting included a presentation by EPA staff to explain the 

results of the EPA study. 

The BLM extended the public scoping period to June 21, 2008 to allow more public involvement and 

encourage collaboration among interested parties. Ultimately, over 1000 members of the public, mainly 

off-highway vehicle users, discussed the future management of the Clear Creek Management Area at the 

CCMA scoping meetings in Santa Clara, Hollister, Coalinga, and San Jose. The CCMA RMP Scoping 

Report (August 2008) lists the comments from agencies, organizations, individuals identified during the 

public scoping period. 

2. Public Comment Period 

The public comment period for the CCMA Draft RMP/EIS opened with publication of the Notice of 

Availability for the Draft Resource Management Plan for the Clear Creek Management Area, California, 

and Draft Environmental Impact Statement in the Federal Register (Volume 74, Number 232) on 

December 4, 2009. 

Accordingly, BLM issued a news release on December 17, 2009 announcing three public comment 

meetings for the CCMA Draft RMP/EIS, which were held in Coalinga, Hollister, and Santa Clara,

California. These three public meetings were held in January 2010 to promote public involvement in the 

CCMA land use planning process. A social and economic workshop was also held on February 22, 2010 

to discuss social and economic issues and concerns associated with the range of alternatives in the Draft 

CCMA RMP/EIS. More than 70 members of the public attended the meeting. Participation at the 

socioeconomic workshops included local businesses, ranchers/landowners, clubs and organizations, 

elected public officials, Native Americans, and area residents. 

Overall, attendance during these four meetings was high with over 1000 members of the public 

discussing the future management of the CCMA. Summary reports of these public meeting are included 

in Appendix XI of the CCMA Proposed RMP and Final EIS (2013). The official public comment period 

for the CCMA Draft RMP/EIS was extended to April 19, 2010 to allow further public input following 

requests from numerous planning participants and elected officials. A complete listing of all the agencies, 

organizations, clubs, and individuals, plus a summary of their comments on the CCMA Draft RMP/EIS is 

included in Appendix X of the CCMA PRMP and FEIS, Volume II (BLM 2013). 

3. Public Protest Period 

Following public review and comment on the BLM’s “preferred alternative” analyzed in the CCMA Draft 

RMP/EIS (BLM 2009), the Hollister Field Office developed the CCMA PRMP and FEIS (2013) to 

incorporate substantive public comments and provide BLM’s response based on agency and public input. 

BLM’s official 30-day public protest period for the CCMA PRMP and FEIS began with the publication 

of the Notice of Availability for the Proposed Resource Management Plan and Final Environmental 

Impact Statement for the Clear Creek Management Area in the Federal Register (Volume 78, Number 66) 

on April 05, 2013. The list below provides the names and organizations associated with 21 public 

protests that were filed timely.

This chapter describes the BLM’s RMP for public lands in the CCMA. In determining the appropriate 

land use for CCMA, BLM considered placed an emphasis on managing risk to employees and the public. 

Therefore, the CCMA RMP will limit use that 1) creates high levels of asbestos emissions, 2) creates 

increased opportunity for human exposure to asbestos, and 3) creates a need to conduct intensive 

management in areas with high concentrations of asbestos. The RMP, contained herein, details allowable 

uses, resources protection measures, and management tools that the BLM would implement in order to 

protect human health and safety, natural and cultural resources, and the CCMA’s unique recreation 

opportunities. 

The land use allocations contained in the CCMA RMP establish the official decisions of the United States 

Department of the Interior Bureau of Land Management for federal land use in the CCMA. This RMP 

also details implementation level decisions to address resource management issues on BLM-administered 

lands in the CCMA. The rationale for these decisions is based to the environmental review and analysis 

conducted in the CCMA PRMP and FEIS (BLM 2013). 

1. Purpose and Need 

The purpose of the CCMA RMP is to establish goals, objectives, and management actions for BLMadministered lands in CCMA that address current issues, knowledge, and conditions. The CCMA RMP 

shall guide the management of the lands and resources administered by the Hollister Field Office in 

CCMA to: 1) minimize asbestos exposure 2) reduce asbestos emissions 3) designate areas in CCMA for 

motorized, mechanized, and non-motorized/non-mechanized recreation opportunities; 4) protect sensitive 

natural and cultural resources from impacts due to recreation and other land uses; 5) provide guidance for 

mineral and energy development; and 6) make other land use authorizations and tenure adjustments. 

The need to develop the CCMA RMP arose from numerous changes in circumstances since the current 

land use plan decisions were adopted. The previous RMP for the area was adopted in 1984. There were 

several amendments to the 1984 RMP to address public health and safety and resources protection issues 

in CCMA. However, many other issues that are emerging on public lands were not addressed in those 

amendments. 

2. Planning Area 

The Planning Area includes a portion of southern San Benito County and a portion of western Fresno 

County. BLM public lands account for more than 63,000 of the 75,000 acre management area. BLM also 

administers subsurface minerals on approximately 3,500 acres of “split estate” (areas where BLM 

administers Federal subsurface minerals but the surface is owned by a non-Federal entity). 

The lands managed by the Hollister Field Office include a variety of settings and landforms, including the 

southern Diablo Mountain Range, Hernandez Valley, and three major watersheds. The Pajaro watershed 

drains into the Pacific Ocean: the Arroyo Pasajero and Silver Creek watersheds drain into the San Joaquin

Valley. BLM’s mission is to sustain the health, diversity, and productivity of these public lands for the 

use and enjoyment of present and future generations. 

The public lands in CCMA are typically steep and mountainous. Some lands within the planning area 

consist of chaparral and oak woodland vegetation. Other areas (primarily on the eastern slopes of the 

Diablo Range) consist of annual grassland and half-shrub vegetation. However, the majority of the 

planning area is dominated by the serpentine soil formation known as the New Idria formation, which is 

characterized by sparse vegetation, large barren complexes on hillsides and ridgelines, and a unique forest 

assemblage of foothill, Jeffrey and Coulter pine. Elevations range from 1,100 -- 5,000 feet. 

Within the CCMA boundary is the Serpentine Area of Critical Environmental Concern (ACEC) covering 

approximately 31,000 acres. It was designated as an ACEC upon approval of 1984 Hollister RMP, based 

on the human health risk associated with the naturally occurring asbestos and the occurrence of special 

status plant species endemic to area. The boundaries of the ACEC were defined by mapping of asbestosladen soils derived from the New Idria serpentine formation. This ACEC is sometimes referred to as the 

Hazardous Asbestos Area (HAA). Human disturbance to the soils and plants in the serpentine ACEC is a 

special management concern, because throughout the ACEC, soil formation tends to be slow and the 

topsoil shallow. Plant regeneration is also slow, and accelerated erosion from human activities has 

negatively impacted soil and vegetative resources over the years. Minimizing soil erosion and minimizing 

the damage to vegetation is a management priority. 

Within the Serpentine ACEC is the San Benito Mountain Research Natural Area (RNA), which is 

approximately 4,147 acres in size. RNAs are designated for the protection of public lands having natural 

characteristics that are unusual or that are of scientific or other interest. The San Benito Mountain RNA 

(SBMRNA) was designated because of the unique forest assemblage and vegetation communities 

associated with the serpentine soils. Its’ primary purpose is to provide research and educational 

opportunities while maintaining and protecting a unique assemblage of vegetation in as natural condition 

as possible. 

The Clear Creek Management Area is shown on Map 7 (Special Designations) in Appendix I along with 

the area of the Serpentine ACEC and the SBMRNA. The acreages (rounded to the nearest hundred) of 

these areas are shown in Table 2-1, with a breakdown of BLM, other agencies and private land ownership 

in CCMA.

3. Management Zones 

Five CCMA management zones (identified below) were defined by BLM interdisciplinary staff based on 

similar resources conditions, resource uses, and management issues or trends. The five CCMA 

management zones include: 

1.	 The Serpentine Area of Critical Environmental Concern (ACEC). 

2.	 The Condon Zone, which includes the White Creek drainage area. 

3.	 The Cantua Zone, which includes CCMA public lands in the Cantua drainage, the San Carlos 

Bolsa, and a disjunct parcel near Idria. 

4.	 The Tucker Zone, which includes public lands surrounding Tucker Mountain, Baker, Byles, and 

Cane Canyons, and the main entrance to Clear Creek; and 

5.	 The San Benito River Zone, which comprises scattered parcels that border the Serpentine ACEC 

and other BLM-administered lands in the San Benito River watershed. 

Table 2-2 identifies the total acres of BLM-administered lands for each of the five management zones.

B. Issues Considered but Not Further Analyzed 

The issues listed below were raised during public involvement in the land use planning process and BLM 

determined they were beyond the scope of the CCMA RMP/EIS. A summary of these issues was 

provided in the CCMA PRMP and FEIS (2013) and will not be further discussed in this ROD/RMP. 

1.	 Temporary Closure of Clear Creek Management Area 

2.	 Establishing New OHV Recreation Areas Outside of CCMA 

3.	 Add/Remove Special Designations 

4.	 Revised Statute 2477 

5. Planning Criteria 

The planning criteria identified in the Notice of Intent published in the Federal Register include: 

	 The RMP will be developed in compliance with FLPMA, all other applicable laws, regulations, 

executive orders, and BLM supplemental program guidance. 

 The planning process will include an EIS that will comply with NEPA standards. 

 Economic and social baselines and consequences will be developed in coordination with local 

and county governments. 

 Initiate government to government consultation, including Tribal interests. 

 Consider the extent to which the revised plan reduces airborne asbestos emissions, minimizes 

asbestos exposure, and addresses public health impact of the Hazardous Asbestos Area. 

 Consider the extent to which the revised plan reduces accelerated erosion and offsite transport of 

asbestos fibers on vehicles and clothes due to off-highway vehicle use. 

 All new data collected will have information about the data (metadata) stored in a data base. All 

metadata will meet the Federal Geographic Data Committee (FGDC) standards. 

 The RMP/EIS will incorporate by reference the Standards for Rangeland Health and Guidelines 

for Livestock Grazing Management (2000). 

	 The RMP will result in determinations as required by special program and resource specific 

guidance detailed in Appendix C of the BLM’s Planning Handbook (H-1601-1). 

	 Decisions in the RMP will strive to be compatible with the existing plans and policies of adjacent 

local, State, Tribal, and Federal agencies as long as the decisions are in conformance with legal 

mandates on management of public lands. 

	 Resource allocations must be reasonable and achievable within available technological and 

budgetary constraints. 

The following ‘planning criteria’ were presented in the CCMA Proposed RMP (2013). These criteria 

were based on input from BLM specialists, other agencies, and the public considered during this planning 

process: 

	 The CCMA RMP must provide for the needs of the public land user, while protecting sensitive 

species and habitat, protecting natural and cultural resources, and protecting the unique ecosystem 

within the SBMRNA. 

 BLM shall comply with the State Protocol Agreement between the California BLM and the 

California State Historic Preservation Officer (SHPO). 

 Best Management Practices (BMP) related to watershed improvement projects would continue to 

be implemented to reduce erosion and off-site sedimentation transport.

 BLM would obtain California Department of Fish and Wildlife permits and Clean Water Act 

Section 404 permits from the U.S. Army Corps of Engineers, for stream alteration and BMP 

watershed management practices as necessary and appropriate. 

 All land use decisions for lands acquired within the CCMA boundaries by BLM would be 

incorporated into this RMP/EIS. 

6. Planning Process 

The BLM has three principal levels of land use planning decisions: the RMP level, the activity level, and 

the site-specific level. This RMP focuses on broad resource objectives and direction while providing 

some activity-level guidance and site-specific decisions. 

1. Relationship to BLM Policies, Plans, and Programs 

Additional major plans, policies and programs that apply to BLM land use planning include: 

43 CFR 1610; BLM NEPA Handbook (H-1790-1); BLM Land Use Planning Handbook (H-1601-1) 

43 CFR 1610 states that guidance for preparation and amendment of resource management plans may be 

provided by the Director and State Director, as needed, to help the District and Area Manager and staff 

prepare a specific plan. 

The NEPA Handbook and the Land Use Planning Handbook provide guidance to BLM on the 

requirements of the Federal Land Policy and Management Act (FLPMA), the BLM’s Planning 

Regulations (43 CFR 1600), and the National Environmental Policy Act (NEPA). Nothing in the 

Handbooks supersedes the legal and regulatory mandates in the CFR. The Manual and Handbook provide 

guidance for preparing new Resource Management Plans (RMPs), plan revisions, plan amendments, other 

equivalent plans (e.g., plans adopted from other agencies), and subsequent implementation-level plans. 

Procedures and requirements are set forth to ensure that the BLM’s plans meet regulatory and statutory 

requirements. To the extent possible, this guidance integrates land use planning requirements with 

requirements under NEPA. 

BLM Wilderness Recommendations 

Wilderness studies were completed for all BLM lands as a requirement under Section 603 of the FLPMA, 

and recommendations have been formally submitted to Congress by the President. Therefore, these 

decisions cannot be changed except by Congressional action. In the Planning Area, approximately 1,500 

acres are being managed in the San Benito Mountain Wilderness Study Area until Congress makes the 

final wilderness determination through legislative action. 

Rangeland Health Standards and Guidelines 

The Central California standards for rangeland health and guidelines for livestock grazing management 

were adopted in 2000 for managing grazing on BLM public lands in the planning area. BLM is required 

by policy to use these standards and guidelines for evaluating rangeland health.

Vegetation Treatments Using Herbicides Final Programmatic EIS Record of Decision 

The CCMA RMP is subject to the BLM’s Vegetation Treatments Using Herbicides Final Programmatic 

EIS Record of Decision, approved in September 2007. The Programmatic EIS Record of Decision (ROD) 

has two primary objectives: 1) Determine which herbicide active ingredients are available for use on 

public lands to improve the agency’s ability to control hazardous fuels and unwanted vegetation, and 2) to 

develop a state-of-the-science human health and ecological risk assessment methodology. This 

methodology would serve as the initial standard for assessing human health and ecological risk for 

herbicides that may become available for use in the future. 

Transportation and Travel Management Handbook 

The BLM’s Transportation and Travel Management Handbook (H-8342-1) provides specific guidance for 

the preparing, amending, revising, maintaining, implementing, monitoring, and evaluating, BLM land use 

and travel management plans. It provides further guidance related to the objectives, authorities, 

responsibilities, and policy considerations in BLM Manual 1626, Travel and Transportation Management. 

This strategy is aimed at recognizing the need to support vehicular access while protecting 

environmentally sensitive areas on the public lands. 

Native American Consultation per Executive Orders 12866, 12898, 13084, 13007 and 13175 et seq. 

Executive Order 12866 “Regulatory Planning and Review” intends to enhance planning and coordination 

with respect to both new and existing regulations and to make the process more accessible and open to the 

public. Executive Order 13084 “Consultation and Coordination with Tribal Governments” of 1998 

established requirements for meaningful consultation and collaboration with Indian tribal governments 

with respect to the development of regulatory practices on Federal matters that significantly or uniquely 

affect their communities. Executive Order 13007 “Indian Sacred Sites” refined consultation requirements 

with tribal groups to include the identification of sacred sites or sacred areas that may be affected by 

proposed federal actions. Executive Order 13175 “Consultation and Coordination with Tribal 

Governments” of 2000 further clarified the consultation relationship between the Federal government and 

tribal communities. 

2. Cooperating Agencies 

BLM and the U.S. Environmental Protection Agency (EPA) worked as cooperating agencies under a 

letter of agreement developed for this land use planning process. A cooperating agency assists the lead 

federal agency in developing an EA or EIS. The CEQ regulations implementing NEPA define a 

cooperating agency as any agency that has jurisdiction by law or special expertise for proposals covered 

by NEPA (40 CFR 1501.6). 

3. Consultation and Coordination 

Formal consultation with agencies that have jurisdiction by law or special expertise is a vital component 

of the resource management planning process and environmental impact statement preparation for vesting 

the public in the effort and allowing for full environmental disclosure.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

U.S. Fish and Wildlife Service 

The Bureau completed the original Hollister RMP, which approved land use for the Clear Creek 

Management Area, in 1984. The Hollister RMP decisions for CCMA were amended in 1986 to protect 

serpentine riparian habitats and the highly-erosive soils in Clear Creek Canyon from off-highway vehicle 

(OHV) recreation and mining activities. In a biological opinion (l-1-85-F-67) issued on October 29, 1985, 

the Service concluded that the adoption of the 1985 Clear Creek Canyon Management Plan was not likely 

to jeopardize the continued existence of the San Benito evening-primrose. The biological opinion was 

based on .the Bureau’s proposals to: seek mineral development withdrawal for Clear Creek Canyon; 

encourage concentrated, rather than dispersed, camping; protect and enhance sensitive plant habitat by 

determining the minimum population size necessary to sustain these species; manage habitat to protect or 

enhance these species; and prepare an ecological study for San Benito evening-primrose. 

In 1995, the Bureau completed the Clear Creek Management Area Proposed Resource Management Plan 

Amendment (1995 Plan) and final Environmental Impact Statement (1995 FEIS). The 1995 Plan was 

intended to guide management of the CCMA, including the 30,000-acre Serpentine Area of Critical 

Environmental Concern (ACEC), for the following 15 years (Bureau 1995). The Bureau subsequently 

requested formal consultation with the Service on the effects of implementing the preferred alternative 

described in the 1995 FEIS. 

In a biological opinion (1-8-96-F-20) issued on September 16, 1997, FWS concluded that the Bureau’s 

implementation of the preferred alternative described in the 1995 FEIS, as modified by additional 

protective measures developed during the consultation (Bureau 1997a), was not likely to jeopardize the 

continued existence of the San Benito evening-primrose. 

The proposed action analyzed in the 1997 biological opinion involved five primary activities: (1) reduce 

asbestos exposure and emissions while still providing opportunities for OHV use and minimize dust 

emissions from main roads; (2) protect existing populations of the San Benito evening-primrose and 

attempt to expand its range to areas that have moderate to high potential habitat for the species; (3) reduce 

erosion and sediment transport in all CCMA watersheds; (4) adjust the boundaries of the San Benito 

Mountain Natural Area to include a cross-section of the unique serpentine and adjacent ecotones found 

only within this area; and (5) manage the Clear Creek Management Area for dispersed OHV use and 

establish open or closed areas as conditions and resources warrant. In addition, the Bureau proposed to 

expand an administrative site to store heavy equipment and maintenance vehicles. 

The conclusion reached in biological opinion number I-8-96-F-20 was predicated upon certain elements 

of the preferred alternative along with the measures that the Bureau developed and proposed during the 

consultation, including: limiting OHV recreation to 270 of the existing 420 miles of designated open 

routes; limiting OHV use to 937 of the existing 5,000 acres of open barrens (i.e., play areas); monitoring 

the condition of San Benito evening-primrose occurrences; monitoring compliance by OHV risers; and 

implementing administrative controls (e.g., conditional closure when OHV non-compliance impacts the 

San Benito evening-primrose) in an adaptive management framework (Service 1997). 

In 2005, FWS received a request from the Bureau, dated January 12, 2005, for initiation of formal 

consultation on the effects of the Bureau’s implementation of the CCMA RMP Amendment for Route 

Designation (BLM 2005). Subsequently, the FWS prepared Biological Opinion l-8-05-F-20. After 

reviewing the status of the species that are known or have potential to occur in CCMA and the effects of 

route designation, the Service's biological opinion concludes that transportation and travel management 

on CCMA public lands is not likely to jeopardize the continued existence of any federally listed species.

In 1994, FWS received a request for consultation from the Bureau for oil and gas exploration and 

development administered by the Hollister Field Office. Subsequently, the FWS prepared Biological 

Opinion 1-1-94-F-47. After reviewing the status of the species that are known or have potential to occur 

on public lands available for oil and gas exploration and development, the Service's biological opinion 

concludes that the reasonable foreseeable activities associated with energy development on public lands 

administered by the Hollister Field office are not likely to jeopardize the continued existence of any 

federally listed species. 

In 2007, FWS received a request for consultation from the Bureau for livestock grazing administered by 

the Hollister Field Office in San Benito and Fresno Counties, California. Subsequently, the FWS 

prepared Biological Opinion l-8-08-F-29. After reviewing the status of the species that are known or have 

potential to occur in CCMA and the effects of livestock grazing, the Service's biological opinion 

concludes that livestock grazing is not likely to jeopardize the continued existence of any federally listed 

species. 

On March 27, 2013, BLM sent a letter to the FWS request for concurrence with a Not Likely to 

Adversely Affect (NLAA) determination for federally listed species that are known or have potential to 

occur in the planning area as a result of the Proposed Action analyzed in the Proposed RMP and Final EIS 

(BLM 2013). On September 9, 2013 BLM received a concurrence letter from the Ventura Fish and 

Wildlife Office that says the implementation of the Proposed RMP is not likely to adversely affect 

California condor, longhorn fairy shrimp, vernal pool fairy shrimp, and San Benito evening primrose. 

This concurrence is based on the expected effects of the activities proposed, and the proposed protection 

and avoidance measures, including limited use of the Serpentine ACEC. 

Office of Historic Preservation & State Protocol Agreement 

The California Bureau of Land Management (BLM) utilizes a Programmatic Agreement (PA) approved 

in 1998 for cultural resources management. This PA was revised in 2004 and recently renewed in 2007. 

The PA is tiered to a national Programmatic Agreement (nPA) approved 1997 between the Advisory 

Council on Historic Preservation (ACHP), the Bureau of Land Management (BLM) and the National 

Council of State Historic Preservation Officers. 

Signatories to the Statewide Protocol Agreement in California are the California BLM, the California 

State Historic Preservation Officer and the Nevada State Historic Preservation Officer. It is designed for 

the California BLM to “integrate its historic preservation planning and management decisions with other 

policy and program requirements to the maximum feasible extent in the public interest.” 

The Statewide Protocol Agreement meets Section 106 requirements of the National Historic Preservation 

Act (NHPA) to “take into account the effects of the agency’s undertaking on properties included in or 

eligible for the National Register of Historic Places” as cited in 36 CFR 800.1(a). The PA also provides 

for an enhanced level of consultation between BLM, Federally recognized tribal governments, and nonfederally recognized Native American groups as well. 

Governor’s Review and State Consistency Requirements 

In accordance with the Federal Land Policy and Management Act (FLPMA) and BLM planning 

regulations (43 CFR 1610.3-2), BLM RMPs must be consistent with officially approved or adopted 

resource related plans of State and local governments and must identify any known inconsistencies with 

state or local plans, policies, or programs. BLM also must provide the Governor with up to 60 days in 

which to identify any inconsistencies and submit recommendations.

On March 28, 2013, BLM submitted the CCMA PRMP and FEIS to the Governor’s Office of Planning 

and Research, State Clearinghouse and Planning Unit for review. Pursuant to 43 CFR 1603-2, and after 

consulting with affected State and Local agencies, the Governor’s Office of Planning and Research (OPR) 

determined that the BLM’s Proposed RMP for Clear Creek Management Area is not inconsistent with any 

state or local plans, policies, or programs. 

Partnership with Federal, State, Tribal, and Local Governments 

Exisitng and potential partnerships could help BLM broaden involvement of interested parties in the 

future management of public lands. Agreements with local counties and communities will continue to be 

utilized and explored for activities and needs such as planning, transportation, emergency services, law 

enforcement, infrastructure, and tourism. BLM will seek to incorporate management actions in the 

CCMA RMP that would compliment adjacent communities. 

BLM will also pursue partnerships with private landowners, the California Department of Fish & 

Wildlife, and other organizations to promote the successful acquisition and restoration of public lands. 

Similar partnerships with universities and other academic institutions could also be instrumental in 

establishing a science review team to garner independent reviews for scientific proposals and answering 

scientific questions in the CCMA. Final decisions regarding management actions on each of the partner’s 

lands still rest with the respective agency/organization. 

Other federal, state, and local government agencies have been involved in the development of the CCMA 

RMP, including the U.S. Fish and Wildlife Service (USFWS), California Department of Toxic Substances 

Control (DTSC) and California State Parks Off-Highway Motor Vehicle Recreation Division (OHMVR). 

Fresno County and San Benito County, the two counties within which the CCMA lies, have not 

established cooperating agency status, but maintain interest and involvement in the planning process. 

The OHMVR Division’s comments on the 2009 CCMA Draft RMP/EIS voiced concerns regarding the 

uncertainty related to EPA’s CCMA Asbestos Exposure and Human health Risks Assessment (2008) and 

the adverse impacts of BLM’s land use decisions on OHV recreation opportunities. BLM has previously 

acknowledged these concerns and the controversy related to naturally occurring asbestos exposure in 

CCMA. As a result, the CCMA RMP includes a discussion of criteria that would prompt BLM to 

reevaluate CCMA land use decisions under the objectives for Transportation and Travel Management that 

are consistent with previous land use planning efforts and agreements with other agencies to cooperate 

with on-going studies and/or consider significant new information and potential management responses at 

the CCMA in light of any new findings. 

The BLM Hollister Field Office also has existing agreements with several Federal, State, and local 

agencies to assist in the management of public land resources in the planning area. These agencies 

include: 

 U.S. Environmental Protection Agency 

 U.S. Fish and Wildlife Service 

 California Department of Toxic Substances Control 

 California State Office of Historic Preservation 

 California Department of Forestry & Fire Protection (CALFIRE) 

 California Department of Fish and Wildlife 

 California Regional Water Quality Control Board 

 Monterey Bay Unified Air Pollution Control Districts

The Tachi Yokut Tribe of the Santa Rosa Rancheria is the only federally recognized Native American 

group in the planning area. Representatives of the tribe are aware of BLM’s CCMA RMP/EIS land use 

planning process. In general, they support BLM’s conservation goals in the planning area provided that 

they are informed of any potential impacts to cultural resources or other traditionally used natural 

resources. Non-federally recognized California Indian tribes that were notified and/or consulted include 

members of several Ohlone/Costanoan tribal groups. Members of these tribes also utilize the planning 

area for cultural and Native American traditional uses. Consultation between BLM officials in the 

Hollister Field Office and tribal representatives were conducted for this EIS and many other activities or 

Proposed Actions within the planning area. The BLM will continue to provide an opportunity for the 

Tachi Yokut Tribe and Ohlone/Costanoan tribal members to provide input on future management of 

public lands. 

7. Related Plans 

The CCMA spans two counties, each with their own General Plan. Both San Benito County and Fresno 

County regularly update these General Plans to address economic development, population growth, and 

affordable housing. In addition to these concerns, county General Plans define open space and 

conservation policy in the Hollister Planning Area and opportunities to coordinate with Federal agencies 

such as the BLM. The San Benito County General Plan and the Fresno County General Plan were 

considered in the development of the CCMA RMP and shall be evaluated for consistency during 

implementation of BLM management activities in the planning area. 

A large portion of the CCMA’s Cantua zone has been managed cooperatively with the California 

Department of Fish and Wildlife (CDFW) since the Wildlife Management Plan for the New Idria 

National Cooperative Land and Wildlife Management Area was signed in 1963. The primary species to 

be managed was deer. Important actions included in the plan were resource inventories and spot kill 

maps, with other actions to be cleared with the cooperating agencies. The plan also covered water 

appropriations and improvements. The 1963 management plan was partially implemented, but is 

generally outdated and needs to be revised in coordination with the CDFW and other interested parties. 

BLM and CDFW also signed the San Benito Deer Herd Management Plan in 1984. The plan identifies a 

New Idria subunit that includes lands within CCMA. Recommendations for prescribed burning, harvest 

strategies, and other management tools are provided. In particular, it is recommended habitat 

improvement projects be concentrated on Condon Peak, Meyers Canyon and San Carlos Bolsa and that 

OHV use be restricted in those areas. Herds were historically designated by county, i.e. they were 

delineated by political rather than biological criteria. In recent years CDFW has shifted from the herdmanagement model and is now focusing on Deer Assessment Units (DAUs). Similarly, BLM is signatory 

to a 2008 Memorandum of Understanding (MOU) with other Federal resources agencies and the Western 

Association of Fish and Wildlife Agencies (WAFWA) to manage mule deer on public lands. Parties to 

the MOU agreed to recognize the importance of mule deer in all land use and populations management 

planning. 

8. Policy 

Area Designation and Route Designation 

The BLM designates areas as “limited” where it must restrict OHV use to meet specific resource 

management objectives. In “designating public lands as Open, Limited, or Closed to the use of off-road 

vehicles,” the objective is “to protect the resources of the public lands, to promote the safety of all users 

of those lands, and to minimize conflicts among the various uses of those public lands.” Designation as a

Record of Decision Resource Management Plan
 

“Limited area’ means an area restricted at certain times, in certain areas, and/or to certain vehicular use.” 

“These restrictions may be of any type,” including “types of vehicles;” “permitted or licensed use only;” 

“use on designated roads;” or other restrictions. 

 Outside the Serpentine ACEC, the Limited Use area designation shall be defined as restricting 

motorized use to highway-licensed vehicles and ATV’s/UTV’s on designated routes described in 

Appendix II. 

 Within the Serpentine ACEC, the Limited Use area designation shall be defined as restricting 

motorized use to highway-licensed vehicles with a permit for access to specific destinations 

within the area on the designated route network described in Appendix II. 

 All routes designated open in the CCMA RMP satisfy the route designation criteria described in 

Appendix II. Routes designated as closed under the Limited Area designation in the RMP do not 

contribute to achieving the CCMA resource condition objectives to ensure overall protection of 

human health and the environment from airborne asbestos emissions. 

The designation of routes within the ACEC was based on the Limited Use area designation for the ACEC, 

restricting use to a scenic touring route to promote safety (public health) and minimize conflicts among 

the various uses of the management area. Specific criteria were identified that contributed in selecting the 

scenic touring route, to ensure overall protection of human health and the environment from hazardous 

airborne asbestos emissions. The selected route network will provide access to areas of interest, including 

Clear Creek Canyon, the San Benito Mountain Research Natural Area, Wright Mountain/Joaquin Rocks, 

Goat Mountain, and the upper San Benito River. The selected routes provide the only practical access to 

the aforementioned areas, while providing transportation manageability, route continuity, and avoid 

redundancy and route proliferation. It is acknowledged that some segments of the touring network could 

be substituted with alternate routes, however it was determined that the selected scenic touring route best 

provides access to areas of interest with a broad range of recreation opportunities, accommodating a range 

of highway-licensed vehicles. Segments of the touring route network were primarily selected from the 

“R” routes which have a higher maintenance objective, are generally wider with less gradient, and best 

suited to a range of vehicle types. In certain areas routes were selected from the “T” routes to improve 

connectivity and minimize impacts to sensitive resources. 

Conformance with Regulations 

The CCMA RMP conforms to Executive Order 11644 (Use of Off-Road Vehicles on the Public Lands), 

February 9, 1972 (87 F.R. 2877), Executive Order 11989 (Off-Road Vehicles on Public Lands), May 24, 

1977 (42 F.R. 26959), and 43 CFR 8342.1 based on the following rationale. 

The “Limited” vehicle use area designation allows for a sustainable transportation network within the 

ACEC. This takes into account human health and safety and the implementation of mitigation measures 

that would effectively reduce the risk to human health based on the type of activity and the duration of 

exposure to airborne asbestos emissions evaluated in the CCMA Asbestos Exposure and Human Health 

Risk Assessment (2008). 

9. Changes from the Final EIS to the ROD 

In 2012, BLM approved a new Transportation and Travel Management Handbook (H- 8342-1). To 

comply with the new guidance, minor changes were made to the Proposed Action outlined in the 

Proposed RMP and Final EIS (BLM 2013) to the CCMA RMP adopted in this Record of Decision. These

Administrative Routes 

Appendix II identifies BLM’s administrative routes on the CCMA public lands. These administrative 

routes are for official government use and other authorized uses to provide vehicular access to private 

lands, communication sites, and other valid existing rights. These routes differ from closed routes in that 

they will be regularly maintained and will not be considered for reclamation. Use of administrative routes 

will require a special recreation permit from the Hollister Field Office that is separate from the general 

ACEC access permit. 

B. Management Decisions 

1. Recreation 

A. Goals and Objectives 

The goals for recreation management are to (1) provide a variety of experiences and settings for a 

diversity of users and to meet potential changes in demand while minimizing conflicts with adjacent 

property owners and among user groups; (2) provide a range of recreational use opportunities while 

protecting sensitive natural and cultural resources from human intrusion; (3) promote sharing of ideas, 

resources, and expertise to increase the public’s appreciation and understanding of natural and cultural 

resources on BLM public lands; and (4) disseminate information that will foster responsible behavior in 

order to achieve the highest possible environmental quality on BLM public lands, and (5) reduce public 

asbestos exposure and asbestos emissions while still providing opportunities for access within the ACEC. 

To achieve these goals, the following resource condition objectives are established: 

 Maintain a range of facilities to support recreational uses. 

 Manage recreation use within the ACEC to reduce airborne asbestos emissions and minimize 

asbestos exposure for recreation users, to address associated public health impacts. 

	 Design maps and brochures and educational opportunities to improve visitors’ appreciation and 

understanding of natural and cultural resources on BLM public lands. 

 Create experiences and settings appropriate for the desired outcome within developed and 

undeveloped recreation areas. 

	 Establish and manage intensive-use areas, where the presence of high quality natural resources 

and the current or potential demand warrants intensive management practices to protect areas for 

their scientific, educational, and/or recreational values while accommodating anticipated 

increases in recreational activities in specific areas. 

 Manage recreational facilities to protect natural resources and to meet user needs. 

 Manage commercial, competitive, educational, and organized group recreational activities.

kiosks. 

REC-INT-BG2. Implementation Decision: Cooperate with adjacent private landowners on land 

management activities to the extent possible. 

2. Hazardous Materials and Public Safety 

A. Goals and Objectives 

The goals for hazardous materials and public safety are to (1) protect public health and safety from 

exposure to hazardous materials; (2) protect natural resources by minimizing environmental 

contamination from past and present land uses (i.e., abandoned mine lands) on public lands and BLMowned and operated facilities; (3) improve Public Safety by mitigating physical and chemical hazards; 

(4) comply with Federal, State, and local hazardous materials management laws and regulations; (5) 

maintain the health of ecosystems through assessment, cleanup, and restoration of contaminated lands; (6) 

manage the costs, risks, and liabilities associated with hazardous materials management to reduce the

governments financial liabilities; (7) integrate environmental protection and compliance with all 

environmental statutes into BLM activities. 

To achieve these goals, the following resource condition objectives are established: 

	 Identify best management practices (BMPs) and administrative actions (i.e. supplementary rules) 

to minimize human health risks from exposure to airborne asbestos. This includes limiting time 

and duration of exposure to naturally occurring asbestos within the Serpentine ACEC. 

	 Identify and control imminent hazards or threats to human health and/or the environment from 

hazardous substances releases on public lands (including Abandoned Mine Lands (AML) sites). 

	 Reduce hazardous waste produced by BLM activities and from authorized uses of public lands 

through waste minimization programs that include recycling, reuse, substitution, and other 

innovative, safe, cost-effective methods of pollution prevention. 

	 Ensure that authorized activities on public lands comply with applicable Federal, State, and local 

laws, policies, guidance, and procedures. 

	 Promote working partnerships with states, counties, communities, other Federal agencies, and the 

private sector to prevent pollution and minimize hazardous waste on public lands. Continue to 

support research related to NOA and amphibole asbestos related to impacts to the environment, 

mineralogy, toxicology, and assessment of exposure risks to public health. At a minimum, the 

BLM will re-examine the body of peer-reviewed data available on this subject within three years 

following issuance of a record of decision for the CCMA RMP. 

	 Protect visitors from safety hazards and/or environmental releases of chemicals of concern 

associated with abandoned mine lands (AMLs) and mining activity. 

B. Management Actions 

HAZ-BG1. Land Use Plan Decision: Restrict the type of activity and the number visits for that activity 

as the primary means to control risk to public from asbestos exposure. 

HAZ-A2. Implementation Decision: Monitor for illegal dumping of chemicals on federal lands. 

HAZ-A3. Implementation Decision: Identify mining-related and other public land hazards and 

eliminate or mitigate as soon as possible. 

HAZ-A4. Implementation Decision: Identify and resolve mining related trespasses with priority given 

to those cases where conflicts are occurring with visitor use and safety. 

HAZ-A6. Implementation Decision: Comply with all provisions of the Monterey Bay Unified Air 

Pollution Control District’s remote location exemption (for CCMA) from the ATCM regulation for 

control of airborne asbestos emissions relating to construction, road maintenance, and grading activities. 

HAZ-BG2. Implementation Decision: Use best management practices (BMPs) identified in Appendix 

V for dust abatement on roads and during project implementation. 

HAZ-BG3. Implementation Decision: Reduce emissions within the ACEC on major routes with dust 

suppression and surface hardening techniques as needed. The techniques include, but are not limited to, 

paving, base rock, chip seal, or applications of surfactants (i.e. biodegradable liquid copolymers) to 

stabilize and solidify soils or aggregates and control erosion.

3. Travel and Transportation Management 

A. Goals and Objectives 

The goals for travel and transportation management are to (1) continue to maintain roads for resource 

management purposes; (2) continue to support local counties and the State of California in providing a 

network of roads for movement of people, goods, and services across public lands; (3) provide motorized 

access to areas of interest within the ACEC, (4) manage motorized access use to protect resource values, 

promote public safety, provide responsible motorized access use opportunities where appropriate and 

minimize conflicts among various user groups. 

To achieve these goals, the following resource condition objectives are established: 

	 Reduce asbestos exposure, as well as limit the miles of routes available for motorized use to 

reduce asbestos emissions; while still providing opportunities for motorized recreation use. 

Minimize dust emissions from main roads. 

	 Maintain or enhance water quality in all watersheds. Manage the route network to ensure that 

sensitive species and communities maintain or enhance their condition. Reduce erosion and 

sediment transport in all CCMA watersheds by reducing the number of miles available for vehicle 

use, and by implementing Best Management Practices for all road work. 

 Establish a Scenic Touring Route within the ACEC. Limit travel to route maintenance objective 

level 4 and level 3 roads, to provide safe travel and accommodate a wide range of vehicle types. 

 Provide travel routes to and through BLM-managed lands as appropriate to meet resource 

objectives while providing for private and public access needs. 

 Manage motorized access and mechanized vehicle use in conformance with Area and Route 

designations. 

	 Adopt the following “adaptive management criteria” to reassess CCMA land use decisions and 

implementation decisions associated with human health risks from exposure to airborne asbestos 

fibers, should circumstances change or new information becomes available that warrants 

increases in allowable uses and reducing the limits on trails available for motorized and nonmotorized recreational use in the Serpentine ACEC. 

If any of the following “adaptive management criteria” are met, BLM would reinitiate travel management 

planning in the Serpentine ACEC to modify transportation and travel management decisions adopted in 

this RMP:

o	 Activity based studies that establish effective strategies for reduction in personal exposure to 

asbestos from off-highway vehicle recreation. 

o	 Research results in a significant reduction in the toxicity values for asbestos resulting in a reduced 

excess lifetime cancer risk. 

o	 Chrysotile asbestos is removed from the list of Toxic and Hazardous regulated substances. 

Pursuant to IM 2008-14 and BLM Manual 1626, these adaptive management criteria provide BLM 

flexibility to change route designations in the future and address how those routes would be managed 

within the modified transportation network. At a minimum, the BLM will re-examine the body of peerreviewed data available on this subject within three years following issuance of a record of decision for 

this CCMA RMP to determine if there’s a need to reconsider the decisions in the CCMA RMP. Under 

such a scenario, BLM would collaborate with interested parties to evaluate potential changes to the 

designated route network. The network would be evaluated for suitability for active OHV management 

and for envisioning potential changes in the existing system or addition of new trails that would help meet 

land use plan objectives. Any adaptive management decisions related to recreation access or motorized 

vehicle use would need to conform to Executive Order 11644 (Use of Off-Road Vehicles on the Public 

Lands) and 43 CFR 8342.1 minimization criteria. 

B. Management Actions 

TRANS-E1. Land Use Plan Decision: Designate the Serpentine ACEC as a “Limited” vehicle use area. 

The Limited Use area designation shall be defined as restricting motorized use to a concise network of 

designated routes providing access to key points within the area as a scenic touring route. 

TRANS-E1.25. Implementation Decision: Vehicle use in the Serpentine ACEC would be limited to 

highway-licensed vehicles with a permit. 

TRANS-E1.50. Implementation Decision: Designate the following routes open for vehicle use in the 

Serpentine ACEC: R1, R10, R11, R13, R14, R15, T103, T104, T151, and T153. These designated routes 

would be developed and maintained to BLM standards. 

TRANS-E1.75. Implementation Decision: All other routes and areas in the Serpentine ACEC are 

designated closed or administrative. 

TRANS-E2. Implementation Decision: Develop and maintain transportation facilities (i.e. pull-outs 

and parking areas) in the ACEC on portions of the vehicle touring route with high scenic values, and 

other destinations with unique biological, natural and geologic features within CCMA. 

TRANS-E3. Land Use Plan Decision: Designate the Tucker, Condon, Cantua, and San Benito River 

Zones as “Limited” vehicle use areas and prepare Travel Management Plans to designate routes of travel. 

TRANS-E3.5. Implementation Decision: Vehicle use in the Tucker, Condon, Cantua, and San Benito 

River Zones would be limited to highway licensed vehicles and ATV/UTV use only on designated routes 

(including potential routes and route construction proposals) identified on the Proposed Action Map in 

Appendix I. 

TRANS-E4. Land Use Plan Decision: Develop and maintain routes and trails in the Tucker and Cantua 

Zones for non-motorized recreation following inventory, soil loss assessment, and resources screening

TRANS-E5. Land Use Plan Decision: Enforce temporary closures year-round to protect persons, 

property, and public lands and resources, especially during periods of extreme wet conditions and during 

periods of extreme dry conditions. 

TRANS-E6. Implementation Decision: Maintain approximately 24.5 miles of designated open routes 

and trails in the Condon Zone. 

TRANS-A2. A Land Use Plan Decision: All routes not designated open or administrative are designated 

as closed. OHV use is authorized only on designated open or administrative routes which are signed for 

use. 

TRANS-A4. Implementation Decision: Adopt the route designation methodology described below to 

satisfy minimization criteria outlined in 43 CFR 8342.1 during development of future travel and 

transportation management plans: 

o	 Designation decisions would be based on a variety of data, including previous studies, field 

inventory data, biological, environmental, cultural, and natural and recreation resources, land use, 

and land ownership. 

o	 BLM would consider the level of impact of each route; the number, density, and intensity of use 

of each route and area and its relationship to habitat fragmentation and cumulative effects; and 

ways to minimize the number and intensity of conflicting land uses. 

o	 Evaluate routes relative to designation criteria (see Appendix II) such as, resource sensitivity, soil 

loss, manageability, intended route use, and recreation opportunity. The route designation criteria 

are combined in four tiers roughly corresponding to the criteria’s likelihood of requiring route 

closure, described in Appendix II. 

o	 Establish a Data Element Dictionary for each of the resource screening criteria, representing the 

data on which decisions about authorized vehicle use of routes is based. The data element 

dictionary describes the responses for each criterion. As routes are screened through the criteria 

tables, data element codes are assigned based on staff evaluation. The last digit of the element 

code also represents a scoring feature, with totals greater than nine for all criteria deemed least 

suitable for open designation. Designation of routes would include mitigation measures or 

restoration as needed. 

o	 Refer to Appendix II for a complete listing of resource specific evaluations for each route 

designated “open” for vehicle use in the CCMA RMP and more details about the CCMA route 

designation methodology. 

TRANS-A7. Implementation Decision: Modify the designated route network to resolve visitor use 

conflicts and promote safe public access through minor realignments1 designed to: 

1 “Minor realignment” is defined as a change of no more than 1⁄4 linear mile of an individual designated route. This 

could include the opening of an existing previously closed route that serves the same access need as the route that is 

to be realigned. It could also involve re-routes of a segment of a route, to avoid the above mentioned resource 

conflicts. All new construction will undergo environmental review and NEPA compliance. All realignments and reroutes will be documented in the official record and kept on file at the BLM Field Office.

	 Reduce impact on sensitive species and habitats, 

	 Substantially increase the quality of the recreational experience, but that will not affect sensitive 

species or habitat, or other sensitive resource values, 

	 Avoid mine hazards and private lands. 

TRANS-A13. Implementation Decision: Implement the following BMP’s to reduce environmental 

impacts from travel and transportation management. 

Best Management Practices: BLM will monitor water quality, soil erosion, and sediment conditions 

within the watersheds of the CCMA. The BLM will implement Best Management Practices (BMPs) to 

reduce impacts to watershed resources, and will continue to evaluate and update these measures as needed 

to minimize impacts to water quality, control erosion and sediment production, and protect sensitive 

resources. BMPs related to watershed improvement and road maintenance projects will be implemented 

to reduce erosion and off-site sedimentation transport (see Appendix V). 

TRANS-B5. Implementation Decision: Implement additional BMPs related to transportations and roads 

outlined in Appendix V. Address all route maintenance activities in an annual corrective route 

maintenance plan. Implement route maintenance and improvement projects consistent with the following 

guidance: 

1.	 BLM manuals 9113, H-9113-2, 9114, 

2.	 Federal Highway Administration's (FHWA) Standard Specifications for Construction of Roads 

and Bridges on Federal Highway Projects Standards, US Forest Service Trails Handbook 

2309.18, sections 2.32 a, b, and c; and 

3.	 1995 Pacific Watershed Associates (PWA) report will be used for standards, guidelines, and 

recommendations. 

Resource awareness training would be completed by all operators to ensure compliance with adopted 

route maintenance guidelines, with relevant inventory data incorporated into the training as appropriate. 

The BLM will continue to implement BMPs to reduce impacts to watershed resources and control nonpoint source pollution. Soil loss standards will be used in monitoring and assessment of routes and areas, 

and will serve as the basis in developing corrective route management plans. 

TRANS-FG3. Implementation Decision: Decommission and reclaim closed roads to protect sensitive 

resources, reduce sediment transport, and control erosion. 

TRANS-FG4. Implementation Decision: Implement BMPs to reduce offsite water quality impacts from 

roads and trails that no longer serve their original purpose, or exceed soil loss standards. 

TRANS-FG5. Land Use Plan Decision: Restrict administrative use of roads and trails during periods of 

inclement weather.

4. Biological Resources – Vegetation Resources 

A. Goals and Objectives 

The goals for vegetation resources are to (1) restore, maintain, or improve ecological conditions, natural 

diversity, and associated watersheds of high value, high-risk, native plant communities and unique plant 

assemblages and (2) to restore degraded landscapes and plant communities. 

To achieve these goals, the following resource condition objectives are established: 

 Maintain or improve current ecological values and processes, productivity, and biological 

diversity; 

 Rehabilitate areas affected by wildland fire and other surface-disturbing activities to stabilize 

soils and promote growth of desired plant communities; 

 Prevent the introduction and proliferation of noxious and invasive weeds. 

B. Management Actions 

VEG-A2. Land Use Plan Decision: Manage the native perennial grassland communities to maintain or 

increase the population.

B. Wilderness Study Areas 

1.	 Goals and Objectives 

The goal for managing Wilderness Study Areas (WSAs) is to manage these areas consistently with the 

Wilderness Act of 1964, as applicable. More specific management direction can be found in 3 CFR 6300. 

BLM is required to manage WSAs consistently with Section 603 of the FLPMA and the Interim 

Management Policy for Lands Under Wilderness Review (H-8550-1) until Congress designates the areas 

as wilderness or releases them from the Section 603 FLPMA provision. If the areas are released, they 

would be managed consistently with the provisions within the RMP. 

To achieve these goals, the following resource condition objectives are established: 

	 Manage existing WSAs in conformance with the Interim Management Policy for Lands Under 

Wilderness Review. 

2.	 Management Actions 

WILD-AG1. Land Use Plan Decision: Manage all designated wilderness consistent with the 

Wilderness Act of 1964 and Public Law 107-370-(2)(2). Manage WSAs under the Interim Management 

Policy (H-8550-1) until Congress designates wilderness areas or until non-suitable WSAs are released. 

WILD-AG2. Land Use Plan Decision: Manage the 1,500-acre San Benito Mountain WSA consistent 

with the goals and objectives and the resource management actions for the Serpentine ACEC and the San 

Benito Mountain RNA, if the area is released from WSA status by Congress. 

WILD-AG3. Implementation Decision: Conduct necessary maintenance of routes through the area to 

enhance overall wilderness quality by minimizing route-related impacts to the sensitive resources inside 

the SBMRNA/WSA. Areas along the roadways near the WSA will be rehabilitated using the best 

management practices outlined in Appendix V. 

C. Wild and Scenic Rivers 

Pursuant to BLM Manual 8351 – Wild and Scenic Rivers – Policy and Program Direction for 

Identification, Evaluation and Management, the BLM evaluates identified river segments for their 

eligibility and suitability for Wild and Scenic River designation through its RMP process. The criteria 

and information upon which WSR river eligibility and suitability determinations are based are included in 

Appendix VI. Only Congress can designate Wild and Scenic Rivers to be included in the National Wild 

and Scenic River System (NWSRS). 

1.	 Management Actions 

WSR-AG1. Land Use Plan Decision: None of the river and stream segments on BLM public lands in 

CCMA were determined to be eligible and suitable for inclusion in the Wild and Scenic River System. 

Therefore, BLM recommends that none of the rivers and streams identified in Appendix VI be included in

13. Cultural Resources 

A. Goals and Objectives 

In accordance with BLM policy (DM 8130.23), the goals for cultural resources management are to: 

 Preserve and protect significant cultural resources and ensure that they are available for 

appropriate uses by present and future generations (per FLPMA Sec. 103(c), 201(a), 202(c); 

NHPA Sec. 110(a); ARPA Sec. 14(a)), and 

 Seek to reduce imminent threats and resolve potential conflicts on cultural resources, from natural 

or human-caused deterioration, or from other resource uses (per FLPMA Sec 103(c), NHPA Sec. 

106; 110(a)(2)). 

The BLM’s cultural resources management program relies on an integrated system of identifying and 

evaluating cultural resources, deciding on their appropriate use(s), and administering them according to 

cultural resource law and policy.

The primary objectives for this integrated management system are to: 

	 Respond in a legally sufficient and professional manner concerning historic preservation and 

cultural resource protection; 

	 Recognize the potential public and scientific uses of cultural resources on the public lands, and 

manage the lands and cultural resources so that these uses and values are not diminished but 

rather are maintained and enhanced. 

	 Ensure that proposed land uses, initiated or authorized by BLM, avoid inadvertent damage to 

Federal and non-Federal cultural resources. 

B. Management Actions 

CULT-COM1. Land Use Plan Decision: Protect “at-risk” archeological or other cultural resources, 

including prehistoric and historic sites, using the BMPs available with physical (“on-the-ground”) and/or 

administrative methods to achieve improved site stabilization, protection, or health. 

CULT-COM2. Land Use Plan Decision: Utilize a variety of heritage education programs that promote 

the public stewardship of cultural resources, including but not limited to conventional outreach efforts, 

and participate in the following programs:

Stewardship program, which provide training for volunteer site stewards for site monitoring, 

protection, and enhancement); 

o	 Cooperative Stewardship, which involves the BLM and the California Office of Historic 

Preservation (OHP) in interpretive outreach efforts with involvement from tribes and educational 

institutions; 

o	 Professional and Avocational Societies, in which the BLM attends meetings and conferences to 

enhance public outreach, education goals, and increase awareness of BLM’s cultural resource 

management programs and to support avocational societies to advance cooperative efforts in 

public outreach and education; and 

o	 Archeological and Cultural Awareness Program (ACAP), wherein BLM partners with tribes and 

other Federal and State agencies to conduct evaluations and enhancement projects using 

volunteers. 

CULT-COM3. Land Use Plan Decision: Evaluate and manage all cultural resource properties 

appropriately using the Use Allocation and Desired Outcome management criteria for cultural resources 

below:

17. Fire Management 

A. Goals and Objectives 

The goals for fire management are to (1) establish a fire management program that is cost-efficient and 

commensurate with threats to life, property, public safety, and resources, (2) use fire to restore and/or 

sustain ecosystem health, (3) cooperate with communities at risk within the wildland-urban interface to 

develop plans for risk reduction, (4) cooperate with regional partners in fire and resource management 

across agency boundaries, and (5) reduce man-made fires, with a special emphasis on reductions in 

developed areas such as communities, campgrounds, and transportation corridors. 

To achieve the goals for fire management, the following resource condition objectives are established: 

Wildfire Suppression 

	 Provide for firefighter and public safety in all fire-management activities. 

	 Provide an appropriate management response for all wildland fires, emphasizing firefighter and 

public safety. Areas of Critical Environmental Concern, Research Natural Areas (RNAs), 

Wilderness Study Areas (WSAs), and certain other public lands in the CCMA Special Recreation 

Management Area (SRMA) will require modified suppression techniques to protect the known 

values. Modified suppression techniques are identified in the Hollister Fire Management Plan 

(BLM 2011). 

 Limit the intensity of fire suppression efforts to the most economical response consistent with the 

human and resource values that are at risk. 

 Protect sensitive cultural and paleontological resource sites from damage by fire and/or fire 

suppression actions. 

Fuels Management 

 Reduce the risk of fire in wildland-urban interface communities.
 

 Reduce the risk of catastrophic wildfire through fuels management.
 

 Promote greater diversity within plant communities of the HFO with the use of fire. 

 Use fire as natural land management tool for the control and eradication of noxious weeds. 

 Use fire as a management tool to improve the ecological condition of the area within HFO
 

jurisdiction. 

 Use prescribed burning to reduce the fuel hazard in the chaparral community and for wildlife 

habitat improvement and increased local water yield and watershed enhancement. 

Fire Rehabilitation, Stabilization, and Restoration 

	 Rehabilitate burned areas to mitigate adverse effects of fire on soils, water, and cultural resources 

and vegetation. 

Prevention, Risk Mitigation, and Education 

	 Increase the public’s knowledge of fire’s natural role in the ecosystem and the hazards and risks 

associated with living in the wildland-urban interface. 

 Educate the public on fire safety and prevention measures.

	 Work with the California Department of Forestry and Fire Protection (CALFIRE) to suppress all 

wildfires involving less than 10 acres 90 percent of the time. 

B. Management Actions 

FIRE-BG1. Land Use Plan Decision: Develop and maintain the Hollister Fire Management Plan. 

FIRE-BG2. Land Use Plan Decision: Identify appropriate management response goals, objectives, and 

constraints by specific Fire Management Units (FMUs) in the Hollister Fire Management Plan (Ref. Map 

6, Appendix I). 

FIRE-BG3. Implementation Decision: Employ fire prevention strategies that reduce man-made fires, 

with special emphasis on developed areas such as communities, campgrounds, and transportation 

corridors. 

FIRE-BG4. Implementation Decision: Develop fuels projects to mimic fire’s natural role to enhance 

resource values. 

FIRE-BG5. Land Use Plan Decision: Coordinate with the California Department of Forestry and Fire 

Protection (CALFIRE) or cooperator fire protection entities to develop appropriate management response 

actions, as documented in the annual operating plan, for wildland fires on or threatening BLM lands. 

Primary consideration and operational emphasis are placed on firefighter and public safety, minimizing 

the loss of life and damage to private property, minimizing environmental damage due to suppression 

efforts, and considering resource values and high value habitat at risk from unwanted wildfire. 

FIRE-BG6. Land Use Plan Decision: Identify high priority wildfire risk areas (e.g., wildland-urban 

interface, critical habitats and cultural areas). The Hollister Fire Management Plan (FMP) displays the list 

of values at risk and the communities at risk within each FMU. (These lists may change as communities 

are removed or added each year). 

FIRE-BG7. Implementation Decision: Work collaboratively with Federal, State, Fire Safe Councils, 

and local partners to develop cross boundary fire management strategies and prioritize cross agency fire 

management actions. 

FIRE-BG8. Implementation Decision: Work collaboratively with communities at risk within the 

wildland-urban interface to develop plans for risk reduction. 

FIRE-BG9. Implementation Decision: Work collaboratively with managing partners to design and 

implement prescribed fire and fuels management projects across agency boundaries where this interaction 

would improve the overall success of the project. 

FIRE-BG10. Land Use Plan Decision: Limit the use of fire retardant drops to prevent damage to rock 

art sites and vernal pools and associated aquatic species. Keep retardant away from rock outcrops and 

waterways. 

FIRE-BG11. Implementation Decision: Establish a fire effects monitoring system that inventories preburn species composition and resulting post-fire response, over time. 

FIRE-BG12. Implementation Decision: Monitor fire/fuels treatment effects and adjust the Hollister 

FMP as needed.

Record of Decision Resource Management Plan
 

To achieve this goal, the following resource condition objectives are established: 

 Retain, consolidate, and/or acquire land or interest in land with high public resource values for 

effective administration and improvement of resource management; 

 Make public land available for disposal that meets the disposal criteria contained in Section 

203(a) of the FLPMA; 

	 Meet public, private, and Federal agency needs for realty-related land use authorizations and land 

withdrawals, including those authorizations necessary for wind, solar, biomass, and other forms 

of renewable energy development; 

 Acquire legal public or administrative access to public land; and
 

 Eliminate unauthorized use of public lands.
 

1.	 Land Tenure Adjustments 

A.	 Management Actions 

LTEN-A7. Land Use Plan Decision: Acquire or exchange lands in accordance with the FLPMA and 

other applicable Federal laws and regulations to ensure more efficient management of the public lands, to 

reduce conflicts with other public and private landowners, and to provide more consistency and logic in 

land use patterns within the Hollister Field Office. 

LTEN-EFG1. Land Use Plan Decision: Public lands in the Condon and San Benito River Zones 

identified on the Proposed Action Map in Appendix I would be available for disposal. 

LTEN-EFG2. Land Use Plan Decision: Acquisition of private in-holdings with high value for multiple 

resources including important biological resources and recreational opportunities would be the highest 

priority. 

LTEN-EFG3. Land Use Plan Decision: Consider minor boundary adjustments to facilitate management 

efficiency through sale, exchange, or patent (i.e., less than 50 acres).

landowners in CCMA. 

LUSE-G1. Land Use Plan Decision: Stipulate health and safety mitigation measures for existing 

communication sites and rights-of-way authorizations in the Serpentine ACEC. 

C. Adaptive Management 

BLM acknowledges that controversy exists regarding the health risks of naturally occurring asbestos. 

Therefore, BLM will consider any significant new information related to plan decisions adopted in the 

CCMA RMP to determine whether adaptive management may be warranted throughout the life of this 

Plan. For example, the RMP’s travel and transportation management section identifies “adaptive 

management criteria” that would allow the BLM to make changes to designated route systems and 

addresses how routes may be modified within the transportation network in the future. 

If one of these criteria are met, then BLM would reassess CCMA RMP land use plan decisions associated 

with human health risks from exposure to airborne asbestos fibers, and potentially apply adaptive 

management should significant new information become available that may warrant modifications in the 

limits on days of recreation access and the limits on trails available for motorized use in the ACEC. 

D. Administrative Review and Appeals 

The land use decisions outlined in the Approved RMP are not appealable to the Interior Board of Land 

Appeals. All protests on the CCMA Proposed RMP and Final Environmental Impact Statement (EIS) 

have been resolved, and the decision of the BLM Director is the final decision of the Department of the 

Interior (43 CFR 1610.5-2). 

The decisions outlined in Section II(B) that implement the Clear Creek Management Area Approved 

RMP, are appealable to the Interior Board of Land Appeals, Office of Hearings and Appeals, U.S. 

Department of the Interior. 

E. Appeals 

Pursuant to Departmental policy, "A person may appeal a decision of the Bureau of Land Management 

under the procedures set forth in 43 CFR Part 4, subpart E. See, e.g., 43 CFR §§ 4.411." The relevant

H. Glossary 

Acceptable Risk Range – The Environmental Protection Agency Superfund program defines the 

-4	 -6 acceptable risk range for exposure to a carcinogen, like asbestos, as 10 (1 in 10,000) to 10 (1 in 

1,000,000) excess lifetime cancer risk. Exposures which are calculated to cause more than 1 in 10,000 

excess cancers are considered to be of concern and may require action to reduce the exposure and 

resulting risk. 

Adaptive Management – An iterative process, designed to experimentally compare selected 

management actions by evaluating alternative hypotheses about the ecosystem being managed. Adaptive 

management consists of three parts: management actions, monitoring, and adaptation. Management 

actions are treated as experiments subject to modification. Monitoring is conducted to detect the effects of 

the management actions. Finally, management actions are refined in response to the enhanced 

understanding of how the ecosystem responds. 

Aggregate – Any combination of sand, gravel, and crushed stone in its natural or processed state. 

Allowable uses – for recreation in the CCMA RMP are defined as follows: 

	 Non-motorized – Non-motorized recreation includes hiking, backpacking, bird and wildlife 

viewing, equestrian use, environmental education, sightseeing, picnicking and photography. 

Non-motorized recreation does not include activities listed as motorized or mechanized 

recreation. 

 Mechanized – Mechanized recreation includes cycling, mountain biking, hang gliding, and rock 

climbing using assistive devices. 

 Motorized – Motorized recreation includes the use of off-highway vehicles (OHVs), and scenic 

vehicle touring. 

 Shooting – Shooting, for purposes of this document, includes all non-hunting discharge of 

firearms, but excludes use of paintball devices. 

Alluvium – Unconsolidated rock or sediment deposited by flowing water including gravel, sand, silt, 

clay, and various mixtures thereof. 

Alternative – One of at least two proposed means of meeting planning objectives. 

Animal Unit – One mature (1,000-pound) cow or the equivalent, based on an average forage 

consumption of 26 pounds of dry matter per day. For authorization calculation purposes, an animal unit is 

one cow and her calf, one horse, or five sheep or goats. Depending on the composition and weight of 

animals in the herd, actual forage use may vary. 

Animal Unit Month (AUM) – The amount of forage needed to sustain one cow, five sheep, or five goats 

for 1 month. 

Annual Plant – A plant that completes its life cycle within a single growing season. Also see 

PERENNIAL PLANT. 

Appropriate Management Response (AMR) – The response to a wildland fire based on an evaluation 

of risks to firefighters and public safety; the circumstances under which the fire occurs, including weather 

and fuel conditions; natural and cultural resource management objectives; protection priorities; and values 

to be protected. The evaluation must also include an analysis of the context of the specific fire within the 

overall local geographic area or national wildland fire situation. 

Archaeological Resources Protection Act of 1979 (ARPA) – A federal law that prohibits the removal, 

disturbance, sale, receipt and interstate transportation of archaeological resources obtained illegally

	 Indirect effects, which are caused by the action and are later in time or farther removed in 

distance, but are still reasonably foreseeable. Indirect effects may include growth-inducing effects 

and other effects related to induced changes in the pattern of land use, population density, or 

growth rate and are related effects on air and water and other natural systems, including 

ecosystems.

eligible property is referred to as an historical, cultural, archaeological, or listed property. Also see 

NATIONAL HISTORIC PRESERVATION ACT. 

National Wild And Scenic Rivers System (NWSRS) – A system of nationally designated rivers and 

their immediate environments that have outstanding scenic, recreational, geologic, fish and wildlife, 

historical, cultural, and other similar values and are preserved in a free-flowing condition. The system 

consists of three types of streams: (1) recreation—rivers or sections of rivers that are readily accessible by 

road or railroad and that may have some development along their shorelines and may have undergone 

some impoundments or diversion in the past, (2) scenic—rivers or sections of rivers free of 

impoundments with shorelines or watersheds still largely undeveloped but accessible in places by roads, 

and (3) wild—rivers or sections of rivers free of impoundments and generally inaccessible except by trails

Naturally Occurring Asbestos - Naturally occurring asbestos refers to asbestos minerals that are found 

in the rocks or soil in an area and released into the air by routine human activities or weathering 

processes. Asbestos minerals belong to either the serpentine mineral group or the amphibole mineral 

group. The most common type of asbestos found in California is chrysotile, a serpentine mineral. 

Non-Impairment of Wilderness Values Criteria – A set of criteria regulating land use to protect the 

wilderness values and characteristics of an area until Congress determines whether to preserve it as a 

wilderness. The nonimpairment criteria are as follows. 

 The use, facility, or activity must be temporary. (This means a temporary use that does not create 

surface disturbance or involve permanent placement of facilities may be allowed if such use can 

easily and immediately be terminated upon wilderness designation. 

 When the use, activity, or facility is terminated, the wilderness values must not have been 

degraded so far as to significantly constrain the area’s suitability for preservation as wilderness. 

The only permitted exceptions to the nonimpairment criteria are the following: 

 wildfire or search and rescue emergencies, 

 reclamation to minimize impacts of violations and emergencies, 

 uses and facilities that are considered grandfathered or valid existing rights under the Interim 

Management Policy for Lands under Wilderness Review, 

 uses and facilities that clearly protect or enhance the land’s wilderness values or are the least 

needed for public health and safety, and 

 reclamation of pre-Federal Land Policy and Management Act impacts.

normal variability. 

Rangeland Health Assessment – An estimate or judgment of the status of ecosystem structures, 

functions, or processes, within a specified geographic area (preferably a watershed or a group of 

contiguous watersheds) at a specific time. Rangeland health is assessed by gathering, synthesizing, and 

interpreting information, from observations or data from inventories and monitoring. An assessment 

characterizes the status of resource conditions so that the status can be evaluated relative to land health 

standards. An assessment sets the stage for an evaluation. An assessment is not a decision.

water table of these rivers, streams, lakes, ponds, reservoirs, springs, marshes, seeps, bogs, and wet 

meadows. 

Riparian Species – Plant species occurring within the riparian zone. Obligate species require the 

environmental conditions within the riparian zone; facultative species tolerate the environmental 

conditions and therefore may also occur away from the riparian zone.

PLACES, and SECTION 110 OF THE NATIONAL HISTORIC PRESERVATION ACT. 

Section 110 of the National Historic Preservation Act – The section of the National Historic 

Preservation Act that concerns the managing of federally owned historic properties. Among other 

provisions, Section 110 requires each federal agency to establish a program to locate, inventory, protect, 

restore and nominate to the Secretary of the Interior Standards all properties under its control that appear 

to qualify for the National Register of Historic Places. Also see NATIONAL HISTORIC 

PRESERVATION ACT, NATIONAL REGISTER OF HISTORIC PLACES, and SECTION 106 OF 

THE NATIONAL HISTORIC PRESERVATION ACT.

which particles of rock material accumulate to form sedimentary layers of soil or, over geologic time, 

rock. 

Sediment Load – The amount of sediment, measured in dry weight or by volume that water transports 

through a stream cross-section in a given time. Sediment load consists of sediment suspended in water 

and sediment that moves by sliding, rolling, or bounding on or near the streambed. 

Seeding – The planting of seeds to revegetate land after a disturbance; an area that has been revegetated 

by planting seeds. 

Seral Stages – The development stages of ecological succession. 

Soil Compaction – Compression of the soil, resulting in reduced soil pore space (the spaces between soil 

particles), decreased infiltration of water and air into and within the soil, decreased soil water storage, and 

increased surface runoff and erosion. 

Soil Fertility – The status of a soil with respect to its ability to supply elements essential for plant growth 

without a toxic concentration of any one element. 

Species – From Section 3(15) of the Federal Endangered Species Act: “The term 'species' includes any 

subspecies of fish or wildlife or plants, and any distinct population segment of any species of vertebrate 

fish or wildlife which interbreeds when mature.” A population of individuals that are more or less alike 

and that can breed and produce fertile offspring under natural conditions. 

Species Composition – The proportions of plant species or other organisms in relation to the total on a 

given area. It may be expressed in terms of cover, density, or weight. 

Stabilization (Cultural Resource) – Protective techniques usually applied to structures and ruins to keep 

them in their existing condition, prevent further deterioration, and provide structural safety without 

significant rebuilding. Capping mud-mortared masonry walls with concrete mortar is an example of a 

stabilization technique.

perennial forbs with few shrubs. During mid-seral stages, the woody species on the ecological site such as 

shrubs and trees make an obvious appearance, and annual forbs are dominated by perennial forbs. 

During late-seral stages, shrubs normally dominate plant cover on the site, but the perennial grasses still 

provide the most annual production on into the potential natural community. 

Threatened Species – Any species defined through the Endangered Species Act (ESA) as likely to 

become endangered within the foreseeable future throughout all or a significant portion of its range. Also 

see ENDANGERED SPECIES. 

Trailhead – The terminus of a (motorized or non-motorized) trail accessible by motor vehicle from 

public roadways. 

Trespass – Any occupancy, use, or development of the public lands or their resources of the United 

States without authority.

location for one or more utility rights-of-way. 

Valid Existing Rights (mining) – Locatable mineral development rights that existed when the Federal 

Land Policy and Management Act (FLPMA) was enacted on October 21, 1976. Some areas are 

segregated from entry and location under the Mining Law to protect certain values or allow certain uses. 

Mining claims that existed as of the effective date of the segregation may still be valid if they can meet 

the test of discovery of a valuable mineral required under the Mining Law. Determining the validity of 

mining claims located in segregated lands requires BLM to conduct a validity examination and is called a 

“valid existing rights” determination. 

Vascular Plants – Plants such as the ferns and seed-bearing plants with leaves, stems and roots, in which 

phloem tissue transports sugars from leaves to the stem and roots and xylem tissues transports water and 

dissolved minerals from roots to leaves. 

Vernal Pools- wetlands supplied by rainwater or its drainage consisting of seasonally to semipermanently filled depressions and typically on sites with poor drainage. 

Viable Population – A wildlife or plant population that contains an adequate number of reproductive 

individuals to appropriately ensure the long-term existence of the species. 

Viewshed – The entire area visible from a viewpoint. 

Vigor – The capacity for natural growth and survival of plants and animals.

and establish objectives for managing those values and the management actions to achieve visual 

management objectives. 

Visual Resource Management (VRM) Classes – Categories assigned to public by scenic quality, 

sensitivity level, and distance zones. Each class has an objective that prescribes the amount of 

modification allowed in the landscape. 

Water Right – A right to use, in accord with its priority, a certain portion of the waters of the state for 

irrigation, power, domestic use or another similar use.

Appendix II – Route Designation
 

Vehicle use in the Planning Area is managed under the direction and authority in 43 CFR Part 8340 “OffRoad Vehicles,” and Subpart 8342, “Designation of Roads and Trails.” The off-highway vehicle (OHV) 

regulations apply to use of routes by the general public. Certain other routes may be open to private 

landholders, grazing operators, or other permittees to meet specific access needs and/or legal rights. 

The BLM’s 2006 Record of Decision for CCMA RMP Amendment and Route Designation addressed a 

variety of concerns related to vehicle use, roadways, and resource protection, and provided guidelines for 

future road improvements, maintenance activities, and management decisions. The baseline for analysis 

of transportation in this RMP/EIS is the designated route network that was approved in the 2006 Record 

of Decision for the CCMA RMP Amendment and Route Designation. 

All of the designated routes under the Approved RMP were selected from routes previously designated as 

open in the 2006 CCMA RMP amendment. The Hollister Field Office developed the vehicle use area and 

route designation criteria described in this appendix to minimize conflicts with other resource values and 

public land uses. These designation criteria address a variety of management issues, concerns, and 

resource condition objectives; including the protection of resources of the public lands, the promotion of 

safety of the users of the public lands, and strive to minimize conflicts among the various users of the 

public lands. 

Designation decisions are be based on a variety of data, including previous studies, field inventory data, 

biological, environmental, cultural, natural and recreation resources, land use, and land ownership. This 

process is standardized, repeatable, and can be logically followed; it assesses each route and area, and 

documents that assessment; and establishes a clear link between the designation decision and the rational 

for that decision. 

In compliance with 43 CFR 8342.1, this standardized and stepwise process is designed specifically to 

address identified minimization criteria; whereby routes were evaluated relative to a list of criteria such 

as, resource sensitivity, soil loss, manageability, intended route use, and recreation opportunity. The 

criteria were combined into four tiers (described below), roughly corresponding to the criteria’s likelihood 

of requiring route closure. 

As a result, the routes designated open under the Approved RMP have been screened through the 

minimization criteria using the route designation worksheet illustrated on the following page. 

A route designation table depicting the data elements for each route under the Approved RMP is included 

in this appendix. A map showing the designated route network under the Approved RMP is included in 

Appendix I.

B. Route Designation Criteria 

The following criteria represent the data on which decisions about the authorized recreation use of routes 

is based. The data element dictionary (ref. Appendix II, Section C) describes the allowed responses for 

each criterion. The information on each route will be entered into an electronic database for analysis and 

query. 

The criteria have been combined into four tiers, roughly corresponding to the criteria’s likelihood of 

requiring route closure. Where possible, mitigation measures are discussed that can be used to reduce the 

expected motorized OHV impacts under each criterion. Mitigation, as used in the process, refers to 

management actions that BLM can undertake to alleviate the effects of OHV use with respect to the 

designation criteria. 

Tier One 

These factors can individually result in a closure decisions for a given route. Nevertheless, some of the 

detrimental characteristics identified by these criteria can be successfully mitigated, given sufficient 

funding, staffing, and recreation interest. 

Private Land, State Lands and Mines 

Private and state lands occur throughout the CCMA. To date, managed routes have been maintained to 

reduce erosion by the Bureau without regard to ownership unless the Bureau has specifically been asked 

to assist in preventing OHV and other uses. Where routes desirable for recreation traverse private land, 

the Bureau will seek clarification from landowners about whether or not they wish to allow for OHV use. 

Should a landowner request it, the Bureau will close routes that traverse non-Bureau lands by closing the 

route back to the nearest intersections. The Bureau will seek reciprocal rights-of-way with private 

landowners as appropriate to provide access on primary route connectors. Reroutes to avoid non-Bureau 

lands will be evaluated under a separate Environmental Analysis, given sufficient recreation interest, 

adequate staff and sufficient funds. Mines will be avoided by closing routes leading to or through mined 

areas to avoid subjecting recreation users to increased levels of hazardous materials. 

Mitigation. The Bureau will seek reciprocal rights-of-way with private landowners as appropriate to 

provide access on primary route connectors. Possible mitigation for mined lands will be to sufficiently 

prevent off route travel. Complete fencing of a route, to prevent public access to hazardous mine areas 

can be considered mitigation. Route closure due to private/state lands can possibly be avoided by 

building a new portion of route. 

Special Status Species and Cultural Resources 

Federal laws and BLM policy require protection of sensitive resources, such as threatened and 

endangered species and their habitat and cultural resources. Areas that OHV recreation may adversely 

impact are best protected from such use by avoidance. These types of resources are best protected by not 

having routes bisect occupied or moderate- to high-potential habitat. Sensitive species and their habitat 

are also best protected by distance and adequate natural barriers. Cultural resources are similarly 

sensitive to OHV use impacts and can be managed in a manner analogous to sensitive plants and animals.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

Mitigation. While avoidance is the preferred method to manage OHV use impacts, several strategies 

have also been documented to be successful in protecting sensitive resources. A combination of welldesigned erosion control structures and corridor fencing has greatly reduced OHV use impacts to San 

Benito evening-primrose along Clear Creek Road. It is not currently practical to eliminate the county 

road from the trail system. It is a well-established route and OHV use impacts can generally be 

ameliorated by corridor fencing. Elsewhere, routes should be selected that do not bisect sensitive species 

habitat or cultural resources. 

RNA/WSA 

The management of the 4,147-acre San Benito Mountain Research Natural Area (RNA), including the 

Wilderness Study Area (WSA) CA-040-309 (1500ac), requires special management attention. Pursuant 

to 43 CFR 8342.1(d) routes shall be located in Research Natural Areas only if the authorized officer 

determines that off-road vehicle use in such locations would not adversely affect the values for which the 

area was established. 

Mitigation. No additional routes will be designated in the 1500-acre WSA. Designated routes in the 

RNA may need to be fenced or otherwise limited to reduce potential impacts of OHV trespass off the 

designated open route. 

Riparian Areas 

Riparian areas provide habitat for several sensitive species and generally enhance water quality in the 

watershed. Therefore, riparian areas are to be avoided and impacts from OHV use minimized to the 

extent practicable. Historically, a number of trails used streams as the primary route of travel and resulted 

in impacts to sensitive resources. Routes crossing streams can also impair resources, so the number of 

such crossings should be minimized. Sediment modeling conducted by PTI Environmental Services 

identified a number of sub-watersheds within the Clear Creek watershed that are projected to contribute 

particularly high levels of sediment into Clear Creek. It is especially important that these sub-watersheds 

be evaluated for opportunities to reduce sediment delivery into an active drainage. 

Mitigation. Impacts to riparian zones can be minimized by reducing the number of stream crossings, 

changing their location and/or orientation of the crossing to the stream, or by changing the actual crossing 

by appropriate hardening or utilizing bridges. In using these mitigation measures, it is important to 

design stream crossings that maintain an adequate flow rate so as to discourage yellow-legged frogs from 

attaching egg masses at these high use areas. 

Tier Two 

Criteria within this tier can also result in closure of a route. However, given sufficient recreation interest 

and available funds, actions can be taken to ameliorate most potential negative effects. 

Erosion and Soil Loss Standards 

Routes can cause erosion within the route tread, and through concentrated runoff, to off-tread locations. 

The data for this criterion is gathered following guidance found in the California State Parks 2008 Soil 

Conservation Standard and Guidelines. Besides requirements for signing, route design, and soil 

sustainability, the standards also require corrective actions within specified timeframes. 

Mitigation. Many of the implementation strategies are designed to reduce route use impacts, direct and 

indirect. Most maintenance and corrective actions are relatively inexpensive and can be accomplished in

a timely manner with existing staff. Some corrective actions will need to be carefully justified by 

comparing costs with benefits. Other problem areas can be avoided by constructing reroutes. 

Tier Three 

The criteria within this tier describe the level of recreation interest of a given route, and whether it 

contributes to the recreation opportunity and diversity of recreation experience within the entire CCMA. 

OHV Use/Recreation Spectrum 

Route selection will consider linking visitor desires with recreation opportunities. Nearly all routes have 

some recreation value. Nevertheless, it is important that the open route network contributes to achieving 

the CCMA resource condition objectives. Routes should be selected that provide a wide spectrum of 

recreation use throughout the CCMA. Consideration will be given to the level of recreation interest, 

providing a diversity of trail types and experiences, and allowing for a variety of recreation activities. 

Tier Four 

This tier describes criteria focused on basic issues of route management, including maintenance, 

conflicting uses, official and administrative use, existing rights-of-way, and contribution to the overall 

route network. Consideration may be given, weighing of the costs of managing routes versus the 

recreation benefits of those routes. 

Route Management Objective (RMO) 

While the trail maintenance objective will not trigger a decision on whether to open or close a route, the 

objective does impact the cost (personnel and equipment) of keeping a route open. Similarly, the 

manageability of a route does not necessarily affect the resource impacts of its use, assuming the route is 

adequately managed. However, routes that are difficult to manage/maintain will be costly and given 

current budget constraints may need to be closed for this reason alone. Changing a route’s management 

objective may sufficiently reduce the cost of its maintenance to allow for OHV use. 

Mitigation. The primary way to mitigate the effect of this criteria on route closure are to reduce costs of 

maintenance, through either improved efficiency or use of volunteers, or by reducing the level of required 

maintenance by changing the route designation. 

Administrative Use/Rights of Way 

This criterion considers a limited set of routes for official government use and other authorized uses to 

provide vehicular access to private landowners, permitees, and other valid existing rights-holders. These 

routes differ from closed routes in that they will be regularly maintained and will not be considered for 

reclamation. Use of administrative routes may require a FLPMA right-of-way for private landowners, 

scientific research permits for accredited individuals and organizations, or special recreation permits from 

the Hollister Field Office that are separate from the general access permit for vehicle use on designated 

open routes in the ACEC. 

Mitigation. Permits for use of administrative routes will allow BLM to authorize motorized access to key 

areas of interest for non-motorized recreation.

Record of Decision Resource Management Plan
 

Proliferation and Redundancy 

As it applies to this criterion, route proliferation pertains to whether the individual route may contribute to 

unauthorized use and the creation of new routes, or whether unauthorized use itself created the route. 

Determining whether or not a route is redundant requires considering several factors, including, 

RMO/trail type, proximity to sensitive resources, resource and user conflicts, proliferation, and 

contribution to route network. 

Mitigation. Route proliferation can be reduced in some situations by barrier construction. It may also be 

possible to reroute portions of routes to incorporate existing natural or human-made barriers. 

Route Continuity 

A variety of recreation uses need to be accommodated on the designated route network, possibly creating 

safety concerns or potential user conflicts. Certain dead end routes and spur routes may be desirable with 

appropriate limitations on the use or types of vehicles. 

Mitigation. BLM may install signs to let users know the route has limited OHV use, or is a dead end.

Appendix III - San Benito Mountain Research Natural Area 

Management Plan 

The San Benito Mountain Research Natural Area (SBMRNA), located within the Clear Creek Management Area 

(CCMA), was designated by the BLM in 1999 to encourage research and provide protection of the unique conifer 

forest and vegetation communities on and around San Benito Mountain (BLM 1999). The boundaries of the 

existing SBMRNA were subsequently expanded as identified in the Clear Creek Management Area Resource 

Management Plan Amendment and Route Designation Record of Decision (BLM 2006). This Research Natural 

Area Management Plan guides management of the SBMRNA and identifies management goals and objectives that 

will permit natural processes to continue without interference. 

1.1 Introduction 

The Bureau of Land Management establishes and maintains Research Natural Areas (RNAs) for the primary 

purpose of research and education. RNAs have one or more of the following characteristics (43 CFR 8223 – 

Research Natural Areas): 

 A typical representation of a common plant or animal association; 

 An unusual representation of a common plant or animal association; 

 A threatened or endangered plant or animal species; 

 A typical representation of common geologic, soil, or water features; 

 Outstanding or unusual geologic, soil, or water features. 

Dr. James R. Griffin made the original recommendation to establish the San Benito Mountain Natural Area in 1970, 

declaring that “...it would in no way duplicate any North Coast Range serpentine natural area and would be a highly 

desirable contrast with them.” The San Benito Mountain Research Natural Area (SBMRNA) has outstanding 

features including geology, soils, ecology, and threatened plant species. 

Ultramafic areas are distributed throughout California, primarily in the Sierra Nevada, Klamath Mountains, and 

Coast Ranges. Ultramafic rock (henceforth referred to as “serpentine”) is an igneous rock with very low silica 

content (less than 45%), generally >18% magnesium oxide, high iron oxide, low potassium, and composed of 

usually greater than 90% mafic minerals (dark colored, high magnesium and iron content) (Brooks 1987; Alexander 

et al. 2007). Ultramafic rock types include peridotite and serpentinite (hydrothermally altered). The New Idria 

serpentine mass (synonymous with the BLM designation “Serpentine ACEC”) is outstanding as a geologic feature 

among the serpentine areas of California. It is the largest serpentine area in the South Coast Range at approximately 

30,000 acres in size. The New Idria serpentine mass was formed from peridotite (harzburgite or dunite) which has 

been completely mineralogically-altered, sheared, and crushed to yield a nearly incoherent mass of serpentinite 

(Coleman 1957, 1986, 1996; Mumpton and Thompson 1975; Van Baalen 1995). Metamorphism within the New 

Idria serpentine mass has generated several rare serpentinite-associated minerals which the area is globally famous 

for, including fresnoite, joaquinite, neptunite, and benitoite (Louderback 1907, 1909, Bradley 1909; Pabst 1951; 

Coleman 1957, 1986; Laird and Albee 1972). The New Idria serpentine mass also contains many economicallyimportant minerals including cinnabar (mercury sulfide), chromite (iron-chromium oxide), and chrysotile asbestos, 

which have all been commercially mined during the past 150 years (Coleman 1957, 1986, 1996; Eckel and Meyers 

1946; Matthews 1961; Merritt 1962). Cinnabar was extensively mined adjacent to the SBMRNA (Aurora Mine; San 

Carlos peak mine pit) when New Idria was active. Due to its unique geology and mineral suites, the New Idria 

serpentine mass is a popular mineral collection locality and geological research study site. 

The extremely sheared and pulverized serpentinite bedrock of the New Idria serpentine mass weathers to produce 

soils with adverse chemistry including nutrient deficiency (nitrogen, phosphorus, potassium, calcium) and heavy 

metal toxicity (magnesium, nickel) (Kruckeberg 1984; Alexander et al. 2007; Arroues 2006; Reinsch and Arroues 

2010). The pulverized nature of the bedrock, in combination with the extreme adverse soil conditions have resulted 

in large areas of natural, moonscape barrens completely devoid of vegetation. Areas with greater stability and more

soil development support unique vegetation types including serpentine willow/riparian, serpentine chaparral, and 

mixed conifer forest. The San Benito Mountain mixed conifer forest is the only forest in the world that includes 

Jeffrey (Pinus jeffreyi), Coulter (Pinus coulteri), and foothill (Pinus sabiniana) pines, and incense cedar (Calocedrus 

decurrens) at the same location (Griffin 1974). The presence of Jeffrey and Coulter pines in such close proximity 

has resulted in Jeffrey x Coulter pine hybrids (Zobel 1951a, 1951b; Libby 1958; Griffin 1974; Ledig 2000). The 

area comprising the SBMRNA was clear cut when New Idria was active to supply mine support timbers 

(particularly incense cedar) and cord wood to fuel the retorts at New Idria (Sloane 1914; Griffin 1974). Very few 

old growth trees remain in the SBMRNA. Chaparral was also extensively cut to supply cord wood for the retorts. 

Most of the vegetation has since recovered and represents secondary forest (Griffin 1974). 

1.2 Planning 

1.2.1 Management Goals 

The following management goals will contribute to preserving the values for which the SBMRNA was established: 

	 To protect the globally unique San Benito Mountain mixed conifer forest ecosystem, special status species, 

and the adjacent ecotones in their natural state for science research and educational purposes. The San 

Benito Mountain mixed conifer forest contains conifer tree species that occurs nowhere else together in the 

world (Griffin 1974; Evans et al. 2006). This forest also contains many serpentine endemic herb and shrub 

species. 

	 To define and create an environment for research designed (1) to investigate and better understand the 

geology, biology, ecology, and archaeology, and (2) to build an information base for guiding management 

of this and other serpentine ecosystems on BLM lands. 

	 To allow uses inside the SBMRNA compatible with the primary purpose of the Research Natural Area for 

scientific research and education. 

1.2.2 Management Objectives 

Management objectives result in actions that the BLM and the public evaluate as measures of success in attaining 

the management goals. Because new information will become a part of adaptive management of the SBMRNA and 

nearby ecosystems, the management objectives may evolve over to time to meet legal requirements and public 

expectations. 

The following list includes management objectives that will contribute to permitting natural processes to continue 

within the SBMRNA: 

	 Include and maintain within management constraints, the core area of the San Benito Mountain forest and a 

buffer with the transitional chaparral/woodland habitats that border the Forest for the purpose of 

conservation. 

	 Establish SBMRNA boundaries on the basis of watershed or other natural features. The BLM policy for its 

Research Natural Areas is to “Permit natural processes to continue without interference.” and to 

“Determine the boundaries for all vegetation series representatives. In order to preserve the greatest 

diversity possible, the boundaries will include a variety of elevation, slope, and aspect features, and should 

follow natural boundaries.” 

	 Protect known suboccurrences and potential habitat of San Benito evening primrose and provide conditions 

within the SBMRNA in support of the Recovery Plan that conforms to the Biological Opinion for the San 

Benito evening primrose issued by the U.S. Fish and Wildlife Service (FWS 2005). 

 Protect existing suboccurrences and habitat of all other known BLM sensitive species that occur within the 

SBMRNA boundaries. 

 Protect all cultural resources and encourage public partnerships for research and educational use of the 

SBMRNA. 

 Consult with Native Americans from local tribes for management consistent with traditional Native 

American culture and for full tribal participation in planning, research and environmental education.

	 Facilitate quality research overseen by a knowledgeable committee selected from: universities and 

colleges; other private research institutions; the Native American community; federal and State of 

California government research and regulatory agencies; and public interest groups and advisory 

committees. The committee will identify research needs and guide proposed research. Establishment and 

function of the committee shall meet the provisions established by the Federal Advisory Committee Act 

(FACA). 

	 Foster other uses of the SBMRNA that are compatible with its primary purpose. Provide for continued 

authorized uses such as rights-of-way and easements that are compatible with management values for the 

SBMRNA. 

 Implement the CCMA Resource Management Plan and Record of Decision as they specifically apply to the 

SBMRNA for the protection and improvement of soil, air, water, and biological resources. 

 Develop a Fire Management Plan for the SBMRNA so that the FMO is aware of the sensitive species 

habitat locations and vehicle access routes. 

	 Develop a barren area monitoring and restoration plan that will enable BLM staff to understand factors that 

influence erosion rates on serpentine barrens in order to reduce erosion, sediment transport, and restore 

vegetation buffers. 

	 Develop a natural resource research program to determine characteristics of the unique ecosystem that are 

important and what the management response will be to changes in these characteristics. 

1.3 Natural Resource Inventory 

A comprehensive inventory of the natural resources of SBMRNA is necessary to understand what resources are 

present there and to effectively manage those resources. Natural resources of the SBMRNA that have had little to 

no inventory to date include lichen species, invertebrate species, and bat species. 

1.3.1 Air 

The SBMRNA is located within the North Central Coast air basin. Airborne chrysotile asbestos originating from the 

New Idria serpentine mass portion of the SBMRNA has the potential to adversely affect human health (EPA 2008). 

Chrysotile asbestos is classified as a hazardous air pollutant under the Clean Air Act Amendments of 1990. 

1.3.2 Water 

The SBMRNA includes four major perennial streams including San Carlos Creek, Clear Creek (headwaters), 

Sawmill Creek, and Cantua Creek. The streams are important habitat for riparian zone plant and animal species of 

CCMA, some of which are rare and federally-listed. All four streams originate from the New Idria serpentine mass. 

Rocks and soils of the New Idria serpentine mass contain chrysotile asbestos as well as high concentrations of heavy 

metals including nickel, chromium, cobalt, and mercury (Dynamac Corporation 1998; EPA 2008). Streams of the 

SBMRNA may transport chrysotile asbestos and mercury in sediment loads, adversely impacting wildlife and 

humans. Clear Creek is classified as an impaired watershed due to high levels of mercury. 

1.3.3 Geology and Soils 

The SBMRNA includes the northeastern portion of New Idria serpentine mass and includes a flanking portion of the 

Franciscan formation (sedimentary rock). The geology of CCMA, including the SBMRNA, has been mapped by 

Eckel and Meyers (1946), Coleman (1961), and Van Baalen (1995). The BLM has since mapped (2010 and 2011) 

serpentine masses (tectonic) and serpentine landslides in a high level of detail. 

Large areas of the New Idria serpentine mass (particularly the barrens) are generally mapped as Henneke soil series 

and Igneous rock land in the San Benito county soil survey (Isgrig 1969). The USDA Natural Resource 

Conservation Service (NRCS) recently completed a detailed soil survey for the CCMA in San Benito county in 2011 

to resolve soil series polygon mapping discrepancies across the San Benito - Fresno county line and to more 

accurately describe soils of the New Idria serpentine mass (Reinsch and Arroues 2010). The survey resulted in the

description of five soil series derived from serpentine including Duckworth, Cascara, Flomack, Delmexico, and 

Idriapeak. Additionally two new soil series derived from nonserpentine (sedimentary) rock were described 

including Sancarlos and Borreguero. 

1.3.4 Lichen Species 

Lichens are present on rocks, shrubs, and trees within the SBMRNA. Globally, information about lichens present on 

serpentine rocks and soil is scarce. Some studies have found lichen species that appear to be unique or endemic to 

serpentine substrates (Sirois et al. 1988; Harris et al. 2007). A baseline lichen survey was conducted of serpentine 

and nonserpentine rocks in the CCMA in 2011 (Rajakaruna et al. in press). There were ten collection sites (5 

serpentine, 5 nonserpentine) total distributed throughout the northern CCMA. Three collection localities were in 

close proximity to the SBMRNA: New Idria reservoir (serpentinite; immediately north of the SBMRNA), San 

Benito Mountain peak (serpentinite; within SBMRNA), and San Carlos peak (shale; immediately north of the 

SBMRNA). Of the 119 saxicolous lichen species collected, six including Buellia aethalea, Buellia ocellata, 

Caloplaca oblongula, Rhizocarpon suarinum, Thelocarpon laureri, and Trapelia obtegens, are reported new to 

California. Additionally, an apparently previously undescribed Solenopsora sp. is being genetically sequenced to 

confirm its taxonomic status. The rest of the species encountered are relatively frequent in the lichen flora of 

southern and central California, except Aspicilia praecrenata, a lichen considered to be extirpated from the South 

Coast Range. Although 60 of the lichen species sampled from the 10 collection suites were present only on 

serpentine rocks, it is unclear if any of the species may be regarded as unique or endemic to serpentine. Further 

studies (more extensive collection throughout the CCMA and other nearby serpentine areas) are needed to determine 

if any serpentine endemic lichen species are present. 

1.3.5 Plant Species and Habitats 

The diversity of rare vascular plants is one of the most remarkable features of the CCMA. Rare plant species that 

are known to occur or may occur within the SBMRNA include the federally-listed threatened San Benito evening 

primrose (Camissonia benitensis); CNPS list 1B rayless layia (Layia discoidea), talus fritillary (Fritillaria falcata), 

San Benito fritillary (Fritillaria viridea), Mariposa cryptantha (Cryptantha mariposae), Mt. Diablo phacelia 

(Phacelia phacelioides); and CNPS list 4 Guirado’s goldenrod (Solidago guiradonis), serpentine leptosiphon 

(Leptosiphon ambiguus), San Benito monardella (Monardella antonina ssp. benitensis), Hernandez bluecurls 

(Trichostemma rubisepalum), Andrew’s bedstraw (Galium andrewsii ssp. gatense), Brewer’s blarkia (Clarkia 

breweri), sulphur flower buckwheat (Eriogonum umbellatum var. bahiiforme), one-sided monkeyflower (Mimulus 

fremontii), and Santa Clara thorn mint (Acanthomintha lanceolata). 

Inventories of plant species in the SBMRNA will serve as a baseline for GIS analyses describing the ranges of 

habitat characteristics in which rare plants currently exist, previously existed, or might exist under BLM 

management. These inventories will also serve as a baseline for tracking and mapping non-native invasive plants of 

concern to the BLM and to the California Department of Agriculture. 

Existing information sources from herbarium holdings, expert knowledge, and inventory results will describe: 

 historically known sites 

 historically known sites outside the CCMA, but useful to define critical habitat features inside the CCMA 

 delineation of first approximations of suitable habitat for each rare species 

 plant searches for suitable and occupied habitats 

 refinement of criteria used to delineate suitable and occupied habitats 

 identification of habitat locations that have a high probability to sustain populations without directed BLM 

management or with species-specific directed management. 

1.3.6 Vegetation 

Detailed vegetation classification and mapping has been completed for the SBMRNA and the entire CCMA (Evans 

et al. 2006).

1.3.6.1 San Benito Mountain Mixed Conifer Forest 

Currently, the USDA Forest Service, Pacific Northwest Research Station Forest Inventory and Analysis (FI&A) 

Program has permanent plots, systematically selected throughout the Pacific Coast States. To understand changes in 

the San Benito Mountain mixed conifer forest, the BLM may review data collected over the span of several decades 

by the Forest Service. 

Small isolated populations of conifer tree species in the Central California Coast Region are important globally as 

genetic resources. Jeffrey pine, Coulter pine, and incense cedar from San Benito Mountain resemble island-like 

distributions analogous to that of Monterey pine in the Central Coast Region. As such, they resemble unique genetic 

sources. Ledig (2000) has found that the unique hybrids between Coulter pine and Jeffrey pine from San Benito 

Mountain, first described by Zobel (1951a, 1951b), may have altered the genetic structure of Coulter pines through 

introgression. 

1.3.7 Invertebrate Species 

Little information exists about the diversity or uniqueness of arthropod species present on serpentine soils or in 

streams within the SBMRNA and the entire CCMA. Serpentine endemic insect species have been found at several 

serpentine areas in California (Harrison and Shapiro 1988; Gervais and Shapiro 1999; Schwartz and Wall 2001; 

Boyd 2009). The isolated San Benito Mountain mixed conifer forest within the New Idria serpentine mass 

represents a forest island within a geologic island, providing conditions conducive to specialized adaptation and 

speciation. 

1.3.8 Vertebrate Species 

Amphibians and Reptiles 

Perennial creeks including San Carlos Creek, Clear Creek, and Sawmill Creek are known to harbor BLM sensitive 

foothill yellow-legged frog (Rana boylii) and two-striped garter snake (Thamnophis hammondii). Uplands in the 

SBMRNA are habitat for California horned lizard (Phrynosoma blainvillii). 

Birds 

San Benito Mountain is an important migratory stop for many rare and infrequently seen bird species. The high 

elevation San Benito Mountain mixed conifer forest provides habitat islands for several bird species found nowhere 

else in the Central Coast Range (Johnson and Cicero 1985). Rare migratory birds that stop at San Benito Mountain 

include olive-sided flycatcher (Contopus cooperi), loggerhead shrike (Lanis ludovicianus), yellow-breasted chat 

(Ichteria virens), and grasshopper sparrow (Ammodramus savannarum). Other uncommon bird species include 

mountain quail (Oreortyx pictus), gray flycatcher (Empidonax wrightii), Hammond’s flycatcher (E. hammondii), 

California thrasher (Toxostoma redivivum), rufous-crowned sparrow (Aimophila ruficeps), Bell’s sage sparrow 

(Amphispiza belli spp. belli), and black-chinned sparrow (Spizella atrogularis). 

Mammals 

Presently, no data are available about bats resident in the SBMRNA or in the rest of the CCMA. BLM lands 

elsewhere in California with a history of mining have frequently become important habitats for bats. Abandoned 

mines host bats, mostly as single-species colonies, and perhaps only seasonally as maternity dens, migration rest 

stops, hibernation sites, and colonial roosts during the day. Many bat species are BLM California species of 

management concern. BLM sensitive bats that may be present within the SBMRNA include western mastiff-bat 

(Eumops perotis californicus), Townsend’s western big-eared bat (Corynorhinus townsendi townsendi), pallid bat 

(Antrozus pallidus), Yuma myotis (Myotis yumanensis), long-eared myotis (Myotis evotis), fringed myotis (Myotis 

thysanoides), and small-footed myotis (Myotis ciliolabrum).

1.4 Natural Resource Monitoring 

Natural resource monitoring is essential to determine how ecological processes and species change over time. 

Monitoring results can be used to interpret effects of human activities. 

1.4.1 Air 

Wind erosion and aerial suspension of chrysotile asbestos presents a human health risk. Sampling and modeling of 

human health risk for asbestos under natural conditions has been conducted at the CCMA by research groups and 

the EPA (PTI Environmental Services 1992; EPA 2008). The BLM has an ongoing air sampling program for 

monitoring human exposure to chrysotile asbestos at the CCMA. BLM employees are required to conduct air 

monitoring for personal exposure to chrysotile asbestos whenever they work within the Serpentine ACEC (New 

Idria serpentine mass). Some air monitoring samples are collected within the SBMRNA. 

1.4.2 Water 

Serpentine rocks and soils of the SBMRNA and CCMA contain high concentrations of heavy metals including 

nickel, chromium, cobalt, and mercury (Kruckeberg 1984; Alexander et al. 2007; Arroues 2006; Reinsch and 

Arroues 2010). Clear Creek is classified as an impaired watershed due to high levels of mercury. Trends in heavy 

metal cycling in aquatic ecosystems are important to the overall health of the ecosystem. Concentrations of heavy 

metals often display a seasonal pattern in watersheds. In order to manage watersheds to reduce environmental 

pollutants, it is important to know what environmental pollutants exist and what their concentrations and seasonal 

patterns are. The US Geological Survey monitors water from Clear Creek at a gauging station near Oak Flat 

Campground. 

In addition to heavy metals, erosion and liquid-suspended transport of chrysotile asbestos to water sources also 

presents a human health risk. Water transport of asbestos to the California Aqueduct from the CCMA was detected 

in 1980 (EPA 1991). The asbestos was believed to have originated from the Atlas Mine and was transported by 

water in White Creek to Los Gatos Creek and finally into the aqueduct. The EPA responded with remediation of the 

Atlas Mine in order to prevent further introduction of asbestos into the aqueduct. Large quantities of chrysotile 

asbestos are transported by water out of CCMA into streams and rivers annually. 

Water quality is best monitored by establishing permanent measurement (gauging) stations. Currently, there is no 

formal program by the BLM to monitor water flow, sediment load, or water quality of streams within the SBMRNA 

or elsewhere in the CCMA. 

1.4.3 Geology and Soils 

Organic matter accumulation is an important factor in serpentine soil development and fertility (Alexander et al. 

2007). Pioneer plant species such as buckbrush (Ceanothus cuneatus), manzanita (Arctostaphylos glauca, A. 

pungens), and pines (Pinus sabiniana, P. coulteri, and P. jeffreyi) can establish on barren serpentine soils and 

produce large amounts of leaf litter which decomposes and becomes incorporated into the soil. Increases in soil 

organic matter improve soil conditions for the establishment of secondary plant species such as leather oak (Quercus 

durata), silktassel (Garrya congdonii), toyon (Heteromeles arbutifolia), and many grass and forb species to become 

established within the serpentine plant community. 

Little is known about organic matter cycling and accumulation on the serpentine soils of the SBMRNA. An 

understanding of organic matter cycling is important in understanding how vegetation becomes established on 

serpentine soils. Organic matter accumulation is best monitored by establishing permanent study plots. 

Soil erosion is of great concern to BLM managers due to the high proportion of natural serpentine barrens within the 

SBMRNA and CCMA. Implementing standardized hydrological monitoring for sediment flows and for water 

quality will provide objective and comparable measures of the success of ecosystem management in the SBMRNA

to minimize sediment flows and erosion. Long-term monitoring results can provide watershed-scale models of 

water and sediment flow, as well as changes to stream channel morphology. Water and sediment flows and stream 

morphology are critical factors in the formation and degradation of rare plant habitat such as the stream terraces 

frequently occupied by San Benito evening primrose. 

Soil erosion can be quantified in two ways including soil depth loss as measured by staff gauge grid established 

upon the area of interest, or collection (basin or silt fence) of the sediment eroded from a particular area, downhill of 

that area. Sediment collection is the easiest method. One easy way to measure soil erosion is to establish silt fences 

at key sites of overland erosion (Robichaud and Brown 2002). 

Currently, there is no formal program by the BLM to monitor soil development or erosion within the SBMRNA or 

elsewhere in the CCMA. 

1.4.4 Lichen Species 

Lichens are a sensitive indicator of environmental pollutants. Lichen health can be measured by total cover on rock 

or woody plant surfaces. Lichen colony growth on surfaces can be tracked by measuring its diameter. 

Currently, there is no formal program by the BLM to monitor lichen species within the SBMRNA or elsewhere in 

the CCMA. 

1.4.5 Plant Species and Habitats 

Federally-listed plant species – San Benito evening primrose 

Federally-listed threatened San Benito evening primrose has been monitored by the BLM since 1979. Complete 

monitoring details for San Benito evening primrose can be found in the San Benito evening primrose (Camissonia 

benitensis) Compliance Monitoring and Adaptive Management Plan (Appendix IV). Monitoring includes plant 

counts and documentation of habitat condition. A monitoring report is submitted to the Ventura FWS annually. 

San Benito evening primrose is currently monitored by the BLM within the SBMRNA and throughout the CCMA. 

Other rare plant species 

Rare CNPS List 1B species including rayless layia, talus fritillary, and San Benito fritillary are currently monitored 

within the SBMRNA and throughout the CCMA. Monitoring by the BLM includes plant counts and documentation 

of habitat condition. 

1.4.6 Vegetation 

Vegetation is casually monitored by the BLM within SBMRNA and throughout the CCMA to evaluate human 

impacts and prevent non-allowable human uses (logging/woodcutting; off route vehicle travel). 

1.4.7 Invertebrate Species 

Monitoring of any BLM sensitive invertebrate species populations discovered within SBMRNA and the CCMA may 

be conducted following inventory. 

1.4.8 Vertebrate Species 

Amphibians and Reptiles 

Foothill yellow-legged frog (Rana boylii) is a BLM sensitive species. Although foothill yellow-legged frog is 

declining over its entire range, populations in CCMA appear to be self-sustaining. The BLM developed a

monitoring protocol for foothill yellow-legged frog in 2001 and monitoring is conducted annually throughout the 

CCMA. 

Birds 

Populations of passerine birds in chaparral and forest are of particular concern because these habitats are 

increasingly rare and fragmented. The high-elevation San Benito Mountain mixed conifer forest provides habitat 

islands for several bird species found nowhere else in the Central Coast Range (Johnson and Cicero 1985). Changes 

in the populations of rare bird species that nest in the conifer forest may be an indicator that habitat conditions are 

changing. 

Breeding bird surveys have been conducted annually by the BLM within the SBMRNA and the CCMA since 1995. 

Species monitored include olive-sided flycatcher (Contopus cooperi), loggerhead shrike (Lanis ludovicianus), 

yellow-breasted chat (Ichteria virens), grasshopper sparrow (Ammodramus savannarum), mountain quail (Oreortyx 

pictus), gray flycatcher (Empidonax wrightii), Hammond’s flycatcher (E. hammondii), California thrasher 

(Toxostoma redivivum), rufous-crowned sparrow (Aimophila ruficeps), Bell’s sage sparrow (Amphispiza belli spp. 

belli), and black-chinned sparrow (Spizella atrogularis). 

Mammals 

Monitoring of any BLM sensitive bat species populations discovered in the SBMRNA and the CCMA may be 

conducted following inventory. 

1.5 Natural Resource Research 

Science supports sustainable resource management of the SBMRNA and CCMA, and provides the objective 

information upon which BLM managers make choices for the benefit of the public. The BLM does not presume to 

have sufficient funding to support research of all natural resource types within the SBMRNA. Researchers 

interested in studying natural resources of the SBMRNA come from diverse disciplines and interest groups and from 

diverse government agencies, research institutions, universities in California and other states, and in several 

instances, internationally. The following research topics of interest may be undertaken within the SBMRNA: 

1.5.1 Air 

 Effects of chrysotile asbestos on the health of BLM employees and recreation visitors 

 Modeling air quality impacts under alternate management scenarios, with special reference to the transport of 

air-borne asbestos, mercury, nitrogen- and sulfur-based gases, and ozone 

1.5.2 Water 

 Influence of the extremely sheared (pulverized) New Idria serpentine mass on local hydrology. Curiously, 

Clear Creek maintains high flow rates year-round, even during drought years 

 Heavy metal and chrysotile asbestos transport and cycling in local streams and rivers 

1.5.3 Geology and Soils 

 Mineralogy (rare/unique minerals), geology (ultramafic), and tectonics (New Idria thrust fault) 

 Why are the serpentine barrens so barren? Explore factors including geology (pulverized, unstable geology), 

adverse soil characteristics, and interaction with vegetation and human land use 

 Rate of soil formation and soil erosion under different vegetation types and subject to different types and levels 

of human activities 

 Model soil erosion under alternate management scenarios, with reference to the frequency and severity of 

naturally occurring and human-facilitated erosion

tailings 

	 Human history and land use (pre- and post-European settlement) 

1.5.7 Invertebrate Species 

 Invertebrate adaptations to adverse physical and chemical conditions imposed by serpentine substrates 

 Influence of heavy metals in streams on aquatic invertebrate species 

 Influence of insects (bark beetles) on the Sam Benito Mountain mixed conifer forest 

1.5.8 Vertebrate Species 

	 Influence of heavy metals in streams on aquatic vertebrate species 

	 Invasion by non-native animal species - Ecosystem resistance and management response for control on 

serpentine and nonserpentine soils 

1.5.9 Partnerships 

Funding for science at BLM to improve land management has not been a fiscal priority in the Federal budget. BLM 

cannot depend on internal funding to initiate or support many of the research topics. Without investment, tasks for 

inventories, monitoring protocols, and field research in the SBMRNA would proceed slowly.

The BLM Hollister Field Office staff may contribute their time and other in-kind services to scientists and 

researchers who wish to conduct research. The Field Office staff can continue to foster a setting of engaged inquiry 

with scientists and researchers at the many government agencies and universities located in the counties that 

surround CCMA. 

One important step to facilitating environmental studies in the CCMA has been assistance agreements and 

memoranda of understanding between the BLM California State Office and the University of California and 

California State University systems, established in 2003. At present, the BLM works with the California state 

natural resource agencies and other federal agencies to collaborate on joint watershed planning. The BLM also 

currently works with researchers from the University of California and California State University systems on 

studies of federally-listed plant species recovery, serpentine plant tolerance and evolution and serpentine barrens 

revegetation. Such efforts improve lines of communications between BLM employees and interested scientists from 

regulatory and research agencies and universities. 

The following institutions listed below are active in research that is occurring directly in the CCMA or bearing 

directly on the management issues of the CCMA. The BLM commits itself to working to promote the research work 

of these institutions in the CCMA and to expanding the roster of institutions involved. By promoting science in the 

CCMA, BLM promotes improvement of its own management to remain responsive to social and environmental 

needs for sustainable and robust ecosystems.

1.6.1 Characteristics 

This Fire Management Unit (FMU) ranges in elevation from 2000 to over 5000 feet. The highest peak in the FMU 

is San Benito Mountain at 5,241 feet. The FMU contains nonserpentine chaparral, serpentine barrens, serpentine 

chaparral, and mixed conifer forest. The FMU contains several rare plant species including San Benito evening 

primrose, rayless layia, talus fritillary, and San Benito fritillary. 

1.6.2 Fire History 

Fire history for the SBMRNA may be characterized as one of minimal to infrequent fires, as a result of low fuel 

loads on the low-productivity serpentine soils and barren landscape. Fire ignition is primarily caused by lightning, 

but the potential for fires caused by humans also exists. Serpentine and nonserpentine chaparral poses potential for 

extreme fire behavior. Fire use and prescribed fire have been used in the past to maintain and promote uneven-aged 

brush fields to natural conditions. 

1.6.3 Fire Management Objectives 

1.	 Manage the habitat for threatened and endangered plant and animal species to maintain viable populations 

in their natural ecosystems. 

2.	 Promote natural conditions within SBMRNA plant communities. 

3.	 Restore and maintain structure, species composition, and processes of native ecological communities and 

existing ecosystems. 

4.	 Maintain air quality to meet or exceed applicable federal and state standards and regulations. 

5.	 Use fire to restore and/or sustain ecosystem health based on sound scientific principles and information, 

balanced with other societal goals, including public health and safety, and air quality. 

Management Emphasis – T&E Plants and BLM Sensitive Plants: 

1.	 Protect and improve potential habitat for special status plant species and the San Benito Mountain mixed 

conifer forest. 

2.	 Provide a mosaic of plant community seral stages. 

3.	 Improve native plant community diversity and structure. 

Suppression Objectives: 

1.	 Natural fires should be allowed to burn if they meet fire objectives. Fire retardants and scarification for fire 

lines or breaks should be avoided. A resource advisor from the Hollister Field Office must be notified 

before any retardant drops are planned from aircraft. 

2.	 Fire will be managed for the protection of sensitive resource values, including the San Benito Mountain 

mixed conifer forest. 

3.	 Use existing roads and natural barriers as the preferred method for containment and control of wildfire in 

the FMU. 

4.	 The Monterey Air Board must be notified when any earth disturbance activities occur to conform to the Air 

Toxic Control Measures (ATCM). 

5.	 The potential for the BLM to inherit the wildfire after the first 24 hours of suppression may be possible if 

objectives are not being met in accordance with the RMP and FMP. 

Fire Use and Prescribed Fire Objectives: 

1.	 Prescribed fire may be used to sustain desired characteristics. Specific seasonal timing, patch size, yearly 

total and rotational time for chaparral type fuel is to be coordinated with resource personnel. 

2.	 Fuels treatment may be considered as needed by a site-specific plan. Allow the use of prescribed fire to 

promote natural conditions.

3.	 Use prescribed fire, wildland fires, and mechanical and chemical treatments to protect and maintain rare, 

threatened, and endangered plants and habitat, prevent the spread of invasive plants, and benefit chaparral 

components important to wildlife. 

4.	 Construct hand line and natural fuel breaks and control lines for firing only when necessary, to preserve 

natural fire regimes. 

5.	 Protect and enhance the San Benito Mountain mixed conifer forest within the SBMRNA. 

6.	 All local and state air quality objectives will be met prior to ignition of prescribed fires. 

Post Fire Rehabilitation and/or Restoration Objectives: 

1.	 Immediately initiate post-fire rehabilitation and restoration to stabilize rare, threatened, and/or endangered 

plant habitat. 

2.	 Prevent soil erosion and flooding by constructing water bars and installing erosion control (straw bales, 

straw rolls) on fire lines and fuel breaks. 

3.	 Reseed with a diversity of locally-collected native plant seed in appropriate sites for species, if needed. 

4.	 Monitor for and control invasive plant species. 

Fire Management Strategies: 

1.	 Use of Appropriate Management Response (AMR) to manage all fires for management objectives and 

based on current conditions and fire location. 

2.	 Prevent wildland fires from spreading to private land and the communication site on San Benito Mountain. 

3.	 Use natural barriers for containment. 

4.	 Restore and Rehabilitate fire suppression lines created during fire suppression efforts in a timely manner to 

prevent erosion and stabilize sensitive habitat. 

5.	 Implement the full range of wildland fire fuels management practices, provided they will contribute to 

historical and natural fire patterns. 

BLM’s appropriate management response will address areas where plant communities are at high risk due to current 

conditions or other ecological constraints. Appropriate management response strategies will address critical habitat 

for wildlife, T&E species, areas of soil instability, and preservation of cultural resources. Use appropriate 

management response to prevent wildland fires from spreading to private and other agency lands outside the 

SBMRNA. Once the decadal burn target of 300 acres has been reached from either planned or unplanned ignitions, a 

review of objectives and strategies will lead to new suppression criteria on all wildland fires. 

The appropriate management response is to prevent wildland fires from spreading to private land and to the repeater 

tower on San Benito Mountain. Suppression is coordinated between BLM and CALFIRE. The FMU is within 

Local Responsibility Area where the State provides direct protection under contract with the agency. Due to the 

presence of naturally-occurring asbestos in the FMU, however, CALFIRE will not enter the SBMRNA. Instead, 

CALFIRE will assume a support function outside of the FMU, to prevent further spread of wildfire. If resources are 

needed for suppression within the FMU, local red carded firefighters with hazardous asbestos health and safety 

training and other required training can enter the asbestos area. Additional resources will also need the proper 

training if extended fire suppression is required. Aerial application and the use of natural barriers is the choice for 

containment within the FMU. This FMU has very limited accessibility by land. 

1.7 Allowable Uses 

Uses inconsistent with the preservation of the values for which the SBMRNA was designated will be discouraged. 

Recreation and access must conform to management actions identified in the Approved RMP and be consistent with 

SBMRNA management objectives. Activities involving organized events or commercial activities will need written 

authorization.

Appendix IV - Camissonia benitensis Compliance Monitoring & 

Adaptive Management Plan 

1.0 Introduction 

San Benito evening primrose (Camissonia benitensis) is a federally-listed Threatened plant species which 

occurs on Bureau of Land Management (BLM) public lands in the Clear Creek Management Area 

(CCMA). The Endangered Species Act requires that all Federal agencies ensure that management actions 

do not jeopardize the continued existence of any threatened or endangered species. 

San Benito evening primrose is a strict serpentine (ultramafic rock) endemic found on serpentine alluvial 

stream terraces and on the margins of tectonic serpentine masses and serpentine landslides (serpentine 

geologic transition zone) in southern San Benito county, western Fresno county, and eastern Monterey 

county, California (BLM 2010). Only 10 suboccurrences of San Benito evening primrose were known at 

the time of federal listing in 1985 (USFWS 1985; Figure IV-1). The primary threat to the species 

identified at listing was Off-Highway Vehicle (OHV) impacts. Additional identified threats included other 

recreational activities (camping and rockhounding/mineral prospecting), road construction and 

maintenance, and gravel mining. Most of the suboccurrences known at the time of listing were located in 

the vicinity of heavily-impacted OHV areas (staging areas) on serpentine alluvial stream terraces in Clear 

Creek Canyon within Clear Creek Management Area (CCMA; Kiguchi 1985). Serpentine alluvial stream 

terraces were believed to be the only habitat type for the species. By 2009, all serpentine alluvial stream 

terrace habitat in the Clear Creek Management Area had been exhaustively surveyed for San Benito 

evening primrose, resulting in a total of 64 known natural suboccurrences (BLM 2009; Figure IV-1). Five 

of the 64 suboccurrences were (re)introductions made in 1990 and 1991 (Taylor 1993). Additionally, 

another six suboccurrences were introduced (new introductions) in 2008 for a total of 70 suboccurrences 

(BLM 2009). Many miles of fence and pipe barriers had been constructed to prevent OHV impacts to San 

Benito evening primrose and an OHV route designation (BLM 2006) further reduced OHV impacts. 

The discovery that San Benito evening primrose also grows on serpentine geologic transition zone habitat 

(edges of tectonic serpentine masses and serpentine landslides; uplands) in 2010, followed by intensive 

survey of that habitat type on both BLM and private land resulted in the discovery of another 295 natural 

suboccurrences for a total of 361 suboccurrences known by 2011 (5x increase from 2009; BLM 2010; 

Figure IV-1). New suboccurrence finds on private lands doubled the known species range (Figure IV-2). 

Of the 361 total suboccurrences known, 196 suboccurrences are located within CCMA and 165 

suboccurrences are located outside of CCMA (Table IV-1). Most of the newly discovered suboccurrences 

do not appear to have experienced any significant historic or recent human impacts, as a result of their 

location (largely outside of most areas intensively used by OHVs) and landscape position (often steep and 

brushy areas).

The San Benito evening primrose Compliance Monitoring and Adaptive Management Plan will improve the BLM’s 

ability to manage CCMA in a manner that promotes the long-term conservation of San Benito evening primrose and 

makes efficient use of staffing and funding. This document outlines specific actions and refines the protocol to be 

used in monitoring San Benito evening primrose occupied and potential habitat areas within CCMA. This 

monitoring program documents disturbance to San Benito evening primrose habitat by tracking the type and 

intensity of threats to the species and its habitat to assess the status of the species over time and determine if 

adaptive management is needed. 

This monitoring program builds upon existing BLM documents and strategies that have established protocol for 

compliance monitoring and FWS Biological Opinions for San Benito evening primrose within CCMA (BLM 1997a, 

1997b, 2003, 2005, 2006; USFWS 1997, 2005). 

2.0 Definitions 

2.1 Population Terminology 

Population: Traditionally, a plant population has been defined as a group of individuals of the same species 

occupying an area of habitat small enough to permit interbreeding among all members of the group (Barbour et al. 

1998; Silvertown and Charlesworth 2001). This can be referred to as the biological population definition. Due to the 

difficulty in circumscribing a biological population, biologists have more recently departed from the traditional 

biological population definition and now define a population without the criteria of interbreeding. This definition of 

a population is particularly applicable to San Benito evening primrose since the species is almost exclusively selfpollinating (Taylor 1990). California Natural Diversity Database dispensed of the term “population” and now uses 

the term “occurrence” instead (as defined below). The terms “occurrence” and “suboccurrence”, therefore, are used 

to describe groups of populations and a single population, respectively, of San Benito evening primrose. 

Occurrence: Equivalent to a group of populations. An occurrence is comprised of more than one suboccurrence of 

San Benito evening primrose that are all located within 1⁄4 mile of each other. 

Suboccurrence: Equivalent to a single population. A suboccurrence is a group of San Benito evening primrose 

plants that occur within a specific localized area differing noticeably in habitat characteristics (slope, aspect) from 

any other group of San Benito evening primrose plants within the same occurrence. There are currently 361 known 

suboccurrences of San Benito evening primrose of which, 196 are located within CCMA. 186 of the 196 known 

suboccurrences within CCMA were monitored in 2011. Only 92 of the 196 suboccurrences within CCMA are 

assigned a number designating occurrence-suboccurrence relationship to other suboccurrences. The other 104 

suboccurrences discovered in CCMA in 2010 and 2011 are known only by global positioning satellite (GPS) 

coordinates of their locations. 

2.2 Habitat Terminology 

Serpentine alluvial stream terrace: Alluvial terrace created by the deposition of primarily serpentine sediment, 

adjacent to a stream or river channel (Figure IV-3). Serpentine alluvial stream terraces are topographically limited 

to low points (valleys) as a result of their depositional setting. San Benito evening primrose typically grows on 

older serpentine alluvial stream terraces where there is no longer active sediment deposition or significant erosion 

(stable).

Figure IV-3. Serpentine alluvial stream terrace. Serpentine alluvium eroded from the New Idria serpentine mass 

(visible in upper right corner) was carried by White Creek (visible at far right) and deposited on the stream bank as a 

terrace. San Benito evening primrose grows on the serpentine alluvial stream terrace. 

Serpentine geologic transition zone: Geologic boundary between serpentine and non-serpentine rocks (sedimentary 

or non-ultramafic, metamorphic). The boundary may exist 1) between tectonic serpentine masses and nonserpentine rocks (Figure IV-4), 2) between serpentine landslides originating from tectonic serpentine masses and 

non-serpentine rocks, or 3) between ancient (>10,000 year old) serpentine alluvial deposits (elevated on hillslopes) 

and non-serpentine rocks. There is no topographic position limit for serpentine geologic transition zone. It can 

occur in valleys, on hillslopes, or high on ridges. Vegetation type often dramatically changes at the geologic 

transition zone from dense chaparral to sparse chaparral or blue oak woodland. San Benito evening primrose grows 

on serpentine soils in open gaps of woody vegetation at the edges of tectonic serpentine masses and serpentine 

landslides in the serpentine geologic transition zone.

Figure IV-4. Serpentine geologic transition zone. Serpentine (blue, barren substrate) interfaces with non-serpentine 

rocks (supporting dense annual grassland and blue oak woodland). San Benito evening primrose grows on the 

barren serpentine substrate. 

Occupied habitat: The area occupied by a suboccurrence. 92 suboccurrences of San Benito evening primrose are 

assigned a suboccurrence number with the extent of occupied habitat digitally mapped in geographic information 

systems (GIS). The other 104 suboccurrences have not been assigned a number and are only known only by GPS 

coordinates of their locations with the extent of occupied habitat mapped in GIS. 

Potential habitat: Localized areas of serpentine alluvial stream terraces and serpentine geologic transition zone 

judged to have habitat conditions conducive to supporting San Benito evening primrose. Most potential habitat of 

San Benito evening primrose within CCMA and other areas within its known range has been mapped in GIS. Areas 

of potential habitat are generally, but not always, adjacent to occupied habitat. Conditions conducive to supporting 

San Benito evening primrose have been determined from observations of habitat conditions present where the 

species has been found. Conducive habitat conditions include: 1) serpentine soil on stream terraces (serpentine 

alluvial stream terrace habitat) or at the edges of tectonic serpentine masses and serpentine landslides (serpentine 

geologic transition zone habitat), 2) woody vegetation with open gaps, 3) presence of other common indicator 

companion herbaceous species to San Benito evening primrose, and 4) low density of invasive annual herbaceous 

plant species (Taylor 1990; USFWS 2006; BLM 2010). San Benito evening primrose has been found on two other 

distinct habitat types including serpentine rock outcrops (2 suboccurrences) and shale outcrops/barrens (5 

suboccurrences) within- or close proximity to the New Idria serpentine mass (BLM 2010). The rock outcrops have 

habitat conditions similar to geologic transition zone habitat, but it is unclear what additional specific habitat 

conditions on rock outcrops dictate whether they are conducive to supporting San Benito evening primrose. Due to 

this uncertainty, no potential habitat has been mapped for serpentine rock outcrops or shale rock outcrops/barrens.

2.3 Noncompliance Terminology 

Baseline: Baseline conditions noted the previous monitoring visit. The habitat conditions documented during the 

previous monitoring visit are the baseline for the following monitoring visit. 

Non-compliance: Motorized and non-motorized trespass and unauthorized use in occupied and/or potential habitat. 

Incident: A non-compliant incident is unauthorized human disturbance (impact) to habitat that is observed and is a 

change from the previous monitoring visit. Each visit is relative to the baseline condition from the previous 

monitoring visit. 

Disturbance: Disturbance (impacts) to San Benito evening primrose occupied and/or potential habitat resulting from 

human activities. Disturbances can directly impact San Benito evening primrose by damaging plants or degrading 

their habitat. Motorized disturbance sources (Table IV-2) include, but are not limited to: automobiles (full-sized 

vehicle), all-terrain vehicles (ATVs; quads; four wheelers), utility vehicles (UTVs; side by sides), motorcycles 

(primarily dirt bikes), and tractors (tracked vehicles; caterpillars). OHV disturbances are the most common human 

disturbance to San Benito evening primrose at CCMA and the primary threat for which the species was listed 

(USFWS 1985). Non-motorized disturbance sources (Table IV-3) include, but are not limited to: bicycles 

(primarily mountain bikes) and other non-motorized vehicles, camping, rockhounding/mineral prospecting, 

logging/wood cutting, concentrated human foot traffic (trailing), concentrated livestock traffic (trailing), and waste 

(garbage) dumping. The primary habitat disturbances (immediate impacts) from single incidents of motorized and 

non-motorized activities are soil surface disturbance (tracks), soil subsurface disturbance (in the case of activities 

involving digging), and vegetation damage and/or removal. Multiple incidents of these disturbances (depending on 

type, intensity, and degree of localization), can result in greater chronic (long-term) habitat impacts including soil 

compaction, soil erosion, and areas denuded of vegetation. 

Table IV-2. Motorized disturbance sources and primary habitat impacts. 

Table IV-3. Non-motorized disturbance sources and primary habitat impacts. 

It should be noted that not all human disturbances are regarded as adverse to San Benito evening primrose. There is 

strong evidence that some light to moderate level of human disturbance is beneficial to San Benito evening primrose 

(BLM 2009). Several San Benito evening primrose suboccurrences coincide with several prehistoric (Native 

American) and historic (European settler) human habitation sites on serpentine alluvial stream terraces (BLM 2009). 

Human habitation at those sites has been judged to have been beneficial to San Benito evening primrose through the 

removal of woody vegetation (reduction of plant competition) and increase in soil fertility (increased organic matter 

content). In addition to modifying vegetation and soils to promote San Benito evening primrose, humans may have 

also played a role in the dispersal of the species. The seeds of San Benito evening primrose are as small as grains of 

sand and may be dispersed in mud stuck to humans, livestock, and vehicles. Livestock grazing may be beneficial to 

San Benito evening primrose by removing competing vegetation. Wildfire is beneficial to San Benito evening

primrose by removing competing vegetation (BLM 2009). Prescribed fire used by the BLM to control invasive 

yellow starthistle (Centaurea solstitialis) at the confluence of Clear Creek and San Benito River has resulted in the 

(re)colonization of San Benito evening primrose in that area. 

3.0 Habitat and Compliance Monitoring Program 

The monitoring year for San Benito evening primrose begins June 1 and ends June 1 the following year. Minimum 

habitat and compliance monitoring frequency will occur annually (coincident with plant counts). Monitoring 

frequency may be increased in response to increased visitor use and/or increased incidence of non-compliance. 

3.1 Plant Counts 

Plant counts will be conducted annually April – May (peak flowering). San Benito evening primrose can have large 

variation (up to four orders of magnitude) in the number of plants from year to year. San Benito evening primrose 

plants will be directly counted for each suboccurrence monitored where suboccurrences are 1000 plants in size or 

less. For suboccurrences 1000 plants in size or greater, if plant density is fairly even, the count for a small area can 

be extrapolated to the entire suboccurrence. If the distribution and density are uneven, estimates can be made based 

upon random plots. 

3.2 Habitat Condition and Compliance Monitoring 

San Benito evening primrose occupied and potential habitat monitoring will include documentation of significant 

human disturbances (impacts) as listed in Table IV-2 and IV-3. Documentation of disturbances will include the 

following: 

 Suboccurrence impacted (identify by suboccurrence number or GPS coordinate) and whether the 

disturbance occurred within occupied and/or potential habitat. 

 Type (source) of disturbance. 

 Intensity of disturbance. Description of the extent of the disturbance (number of tracks/trails; estimated 

area of disturbed soil and/or vegetation). 

 Photodocumentation of the disturbance. 

The BLM will respond to incidents of non-compliance with a hierarchical approach. Signs and barriers will be used 

in situations of low to moderate levels of noncompliance. Area closures may be enacted in situations of high levels 

of non-compliance (heavy, repeated impacts to numerous suboccurrences). Area closures will be determined in 

consultation with Ventura FWS. Any enacted closures within CCMA will be conducted in accordance with The 

Endangered Species Act of 1973, 43 CFR 8341.2, and 43 CFR 8341.1. 

Endangered Species Act of 1973 

(d) Protective Regulations.- Whenever any species is listed as a threatened species pursuant to subsection (c) of this 

section, the Secretary shall issue such regulations as he deems necessary and advisable to provide for the 

conservation of such species. The Secretary may by regulation prohibit with respect to any threatened species any 

act prohibited under section 9(a)(1), in the case of fish or wildlife, or section 9(a)(2) in the case of plants, with 

respect to endangered species; except that with respect to the taking of resident species of fish or wildlife, such, 

regulations shall apply in any State which has entered into a cooperative agreement pursuant to section 6(c) of this 

Act only to the extent that such regulations have also been adopted by such State. 

43 CFR 8341.2 Special Rules

(7) Include a statement on the reasons for the closure; and 

(c) In issuing orders pursuant to this section, the authorized officer shall publish them in the Federal Register. 

(d) Any person who fails to comply with a closure or restriction order issued under this subpart may be subject to the 

penalties provided in Sec. 8360.0–7 of this title. 

3.3 Reporting 

Monitoring reports will be generated annually and submitted to the Ventura FWS. The report will summarize 

ongoing management to protect San Benito evening primrose suboccurrences and potential habitat on BLM land 

within CCMA. 

Reports will include the following: 

	 Suboccurrence monitoring data including plant counts 

	 Inventory results of surveyed habitat 

	 Habitat restoration summary 

	 Recovery research summary 

	 Compliance monitoring record 

	 Description and photos of non-compliance incidents 

	 Recommendations for changes in management to reduce non-compliance and promote recovery of the 

species 

4.0 Adaptive Management 

The following measures can be implemented to increase protection of San Benito evening primrose habitat from 

unauthorized activities if compliance monitoring indicates that existing protection is insufficient to control impacts 

to habitat. The protection measures should be applied with respect to the specific unauthorized activity and the 

location where the unauthorized activity is occurring. The measures should be applied in a stepwise process. 

1.	 Site Monitoring - Increase frequency of monitoring at specific suboccurrences experiencing chronic noncompliance. 

2.	 Signing - Increase signing. Sign for educational and law enforcement purposes (i.e. Vegetation Study Area 

and Closed Area) unless vandalism is a risk.

3.	 Fencing - Continued non-compliance will determine if barrier installation (fence or pipe) is necessary. 

Wire fencing provides an effective, lower cost option to exclude unauthorized human activities from 

protected areas. This type of barrier, however, is often more susceptible to vandalism (fence cutting and 

damage from OHVs) than robust, steel pipe barriers. 

4.	 Pipe barrier – Pipe barrier is constructed from welded segments of 2.5” diameter steel pipe. Pipe barrier 

installation is substantially more expensive to install than wire fencing, but its robust construction provides 

greater protection of sensitive areas, particularly from motorized vehicles which are capable of damaging 

wire fences. 

5.	 Closures - Close trails, sub-watersheds, entire watersheds and larger areas, or the entire CCMA when 

monitoring shows continued non-compliance in San Benito evening primrose occupied and potential 

habitat on BLM managed lands. Closures at the sub-watershed and larger areas will be determined in 

consultation with the FWS to determine appropriate adaptive management actions. 

5.0 Annual review with the U.S. Fish and Wildlife Service 

The BLM will confer with the Ventura FWS on an annual basis to review monitoring data and what measures the 

BLM has taken to remedy any problems that were identified. The conference can initially be via e-mail and phone, 

though either party reserves the right to request an in-person meeting. If substantial disagreement arises between the 

agencies regarding appropriate management response to issues related to protection and conservation of San Benito 

evening primrose, the FWS may request that formal consultation be reinitiated.

Appendix V - Best Management Practices
 

The following management practices were compiled from various sources listed in the reference section. 

These practices are listed as methods for correcting problems related to CCMA travel management and 

watershed issues associated with dust suppression, hazardous materials releases, and soil loss and erosion. 

Many of these management practices are specific measures which will need additional study to determine 

how or if they effectively apply to the specific conditions in the Clear Creek Management Area. 

All of these management practices would need to be monitored and evaluated to determine their overall 

effectiveness and protection of human health and the environment. These management practices have 

been grouped into the following, broad categories: watershed restoration/management, barrens 

restoration/management, transportation and roads, abandoned mine lands (AML) and mining activities, 

and recreation facilities. 

A. Watershed Management & Restoration 

BLM’S watershed management goals related to soil loss are based on limiting sediment production from 

roads, trails, and disturbed areas (hill climbs, mining areas), avoiding vegetation and stream channel 

disturbance, and minimizing mass movement of soil into stream channels (from steep slopes and mining 

areas). 

The following is a list of Management Practices (MP) that have been implemented and will continue to be 

implemented, practices that will be further developed, and management practices that will need further 

evaluation and planning prior to implementation. Continued implementation of management actions 

related to controlling erosion and sediment yield to minimize impacts to watershed resources are 

generally within the capability and budget constraints of the BLM. In all cases, MPs will be identified 

that best address resource condition objectives and will be phased in over a period of time. 

MP-1: Protection of Unstable Areas 

Objective: To provide for protection of unstable areas and thereby avoid triggering mass movements 

of the soil mantle and resultant erosion and sedimentation. 

Explanation: This management practice will help protect unstable areas by reducing or stabilizing their 

high erosion rates. Unstable slopes will be protected by use of fences and barriers to eliminate or channel 

vehicle use away from these areas, and by use of gully plugs, water diversions, etc. as needed. 

MP-2: Streamside Management Zone Designation 

Objective: To designate a zone along streams where prescriptions are made that will minimize the 

adverse effects of nearby land disturbance activities including roads, by: (1) acting as an effective filter 

for sediment generated by erosion from road fills and dust drift; (2) maintaining shade riparian habitat 

(aquatic and terrestrial), and channel stabilizing effects; (3) keeping the floodplain surface in a resistant, 

undisturbed condition to limit erosion by flood flows. 

Explanation: Activities near streams need to be carefully designed and managed. At designated roads 

and stream crossings, fill and side cast material must be kept at a distance from nearby streams to 

minimize their impact on the critical riparian zone and on the stream itself. Factors such as stream class 

118

Record of Decision Resource Management Plan
 

channel aspect, channel stability, side-slope steepness, and slope stability are considered in determining 

the constraints of activities and width of stream side management zones. It is vital to stabilize till slopes 

before the stream side management zone is saturated with sediment. The streamside management zone is 

not a zone of exclusion, but a zone of closely managed activity. It is a zone which acts as an effective 

filter and absorptive zone for sediment, maintains shade, protects aquatic and terrestrial riparian habitats, 

protects channel and stream banks, and promotes flood plain stability. 

MP-3: Restrict Development within the Floodplain 

Objective: To avoid, where possible, the long and short-term adverse impacts to water quality 

associated with the occupancy and modification of floodplains. 

Explanation: A floodplain analysis and evaluation will be made when sites within floodplains are 

being considered for structures or developments. Environmental quality, ecological effects, and 

individual safety and health are considered. Flood frequencies, watershed conditions, climatic and 

environmental factors associated with past flood events, flood flow quantities and specific flood 

boundaries are all evaluated. 

MP-4: Specifying Riprap Composition 

Objective: To minimize sediment production associated with the installation and utilization of riprap 

materials. 

Explanation: Riprap is commonly used to armor stream banks, stream crossings, and drainage ways 

from the erosive forces of flowing water. Riprap must be sized and installed in such a way that it 

effectively resists erosive water velocities. Stone used for riprap should be free from weakly structured 

rock, organic material and materials of insufficient size, all of which are not resistant to stream flow and 

would only serve as sediment sources. Outlets of drainage facilities in erodible soils commonly require 

riprap for energy dissipation. The Corps of Engineers and Federal Highway Administration procedures 

are commonly used for designing riprap structures. 

MP-5: Re-vegetation of Surface Disturbed Areas 

Objective: To protect water quality by minimizing soil erosion through the stabilizing influence of 

vegetation. 

Explanation: This is a corrective practice to stabilize the soil surface of a disturbed area. The 

vegetation selected will be a mix of species best suited to meet the management objectives of the area, be 

it wildlife, recreation, watershed, or fuels management. Endemic species (grass or browse shrubs) may be 

used between recently planted trees where appropriate for aesthetics, erosion prevention or wildlife needs. 

The factors evaluated are soil fertility, slope, aspect, soil water holding capacity, climatic variables, and 

suitable species selection. Re-vegetation of some disturbed areas in serpentine soils may not be feasible. 

MP-6: Watershed Restoration 

Objective: To improve water quality and soil stability. 

Explanation: Watershed restoration is a corrective measure to: (1) repair degraded watershed 

conditions and restore the hydrologic balance with a vegetative cover that will maintain or improve soil 

stability, reduce surface runoff, increase infiltration, and reduce flood occurrence and flood damages; (2)

conserve the basic soil resource; (3) maintain and improve water availability; and (4) enhance economic, 

social, and scenic benefits of the watershed. Factors considered are: predicted change in water quality, 

downstream values, on-site productivity, threat to life and property, direct and indirect economic returns, 

and social and scenic benefits. Examples of watershed restoration measures are gabion structures, back 

filling gullies with rock, and constructing water diversions. 

MP-7: Erosion Control Structure Maintenance 

Objective: To ensure that constructed erosion control structures are stabilized and working. 

Explanation: Erosion control structures are only effective when they are in good repair and stable 

condition. Once the erosion control structures are constructed and seeded where practicable, there is a 

possibility that they may not become adequately vegetated or stabilized or they may become damaged 

from subsequent activities. It is necessary to provide follow-up inspections and structural maintenance in 

order to avoid these problems and insure adequate erosion control. 

MP-8: Abandoned Road and Trail Restoration and Reclamation 

Objective: To improve water quality and soil stability. 

Explanation: Route restoration is a corrective measure to: (1) repair degraded route conditions and 

restore the hydrologic balance with a vegetative cover that will maintain or improve soil stability, reduce 

surface runoff, increase infiltration, and reduce flood occurrence and flood damages; (2) conserve the 

basic soil resource; (3) maintain and improve water availability; and (4) enhance economic, social, and 

scenic benefits of the watershed. Factors considered are: predicted change in water quality, downstream 

values, on-site productivity, threat to life and property, direct and indirect economic returns, and social 

and scenic benefits. Examples of route restoration measures are soil de-compaction, vertical and 

horizontal mulching, transplanting and re-seeding vegetation, re-establishing natural drainage features and 

utilization of temporary water management features. 

B. Barren Areas Management & Restoration 

The purpose of this section is to present sediment and erosion control BMPs that are potentially 

applicable for serpentine barrens in CCMA. Due to the variable topography, sub-climates, soil types, and 

vegetation), these BMPs will be implemented, as feasible, based on budgetary and technical constraints. 

BLM will identify the most effective BMPs and designs in order to maintain or restore other serpentine 

barrens with similar features in the Clear Creek Management Area. 

MP-9: Silt Fences 

Objective: A silt fence consists of a geotextile fabric attached to supporting poles, which is used to 

intercept, reduce velocity, and filter surface runoff. 

Explanation: Silt fences are effective in areas where sheet flow occurs for example, at lower end of 

active play areas, particularly at the interface between a play area and a vegetation buffer; base of slopes; 

and along streams. Silt fences provide retention of runoff sediments, decrease runoff flow velocity and 

energy, protect downslope vegetation from sedimentation and wash-out, and provide visual indication of 

play area lower boundary. Installation does not require construction equipment or skilled labor and is low 

cost.

MP-10: Erosion Control Blankets 

Objective: Erosion control blankets are mats made of synthetic or natural material, or a combination 

of the two, which are stapled to the soil on steep slopes to control erosion and promote the establishment 

of vegetation. 

Explanation: The use of erosion control blankets is limited to narrow strips adjacent to the lateral 

boundaries of vegetated areas located downgradient of active OHV use areas. In order for the blankets to 

be effective, the soil over which they are installed should be of sufficient quality to support vegetation 

growth. The soil surface must be relatively smooth, without rock, deep depressions, or debris. The 

blankets may be seeded to improve the vegetation establishment process. This MP may be combined with 

the use of silt fences, which are described earlier in this section. A silt fence may be installed upgradient 

of a vegetated area and extended laterally to protect the erosion protection blanket strips. Benefits and 

advantages of erosion control blankets include: effective protection of soils on highly erodible slopes: 

they absorb and hold moisture near the soil surface; promote vegetation establishment; may be installed 

on steep slopes; and they do not require construction equipment or skilled labor. 

MP-11: Rock Backfilling of Gullies 

Objective: Filling gullies with loose angular rock prevents further deterioration from water erosion. 

Explanation: This practice is used primarily in naturally incised drainage channels that concentrate 

flow and significantly contribute to sediment generation and transport. This method may be combined 

with the check dam application where lower, more accessible sections of a gully may be backfilled with 

rock and the check dams would be constructed at higher sections of the gully. Benefits of rock backfilling 

include: a decrease in runoff flow velocity and energy; retention of runoff sediment which, over time, 

may clog the void spaces and “heal” the gully; and maintenance can be minimal with proper construction. 

MP-12: Check Dams 

Objective: Check dams decrease runoff flow velocity and energy and provide retention and settling 

of runoff sediments. 

Explanation: Check dams are small structures made of logs, stone, or silt fence that are constructed 

across a gully or ephemeral stream in order to lower the speed, retain sediments, and diminish the erosion 

potential of concentrated flows. Installation does not require construction equipment or skilled labor and 

is low cost. 

MP-13: Interceptor Dyke and Swale 

Objective: Interceptor dykes and swales are used to decrease runoff flow energy, protect downslope 

vegetation from sedimentation and wash-out, and provide visual indication of play area lower boundary. 

Explanation: Dykes are ridges of compacted soil and swales are excavated depressions. A dyke is 

constructed adjacent and downslope of the swale from materials excavated for the construction of the 

swale. In most cases the swale is stabilized with riprap. Dyke and swale systems intercept overland flow 

and convert it into concentrated flow with lower, non-erosive velocity. The diverted flow is discharged to 

a suitable outlet. Dykes differ from silt fences in that it intercepts and diverts all runoff from upload areas, 

whereas, silt fences allow runoff to filter though the fence and reach lower areas.

MP-14: Sediment Basins 

Objective: Sediment basins provide retention of runoff sediments up to 60 to 70%, decrease runoff 

flow velocity and energy, and protect downslope vegetation from sedimentation and wash-out. 

Explanation: A sediment basin is a pond created by constructing a dam across a drainage way, and is 

designed to detain runoff in order to allow suspended sediments to settle. The pond is provided with a 

riser connected to a discharge pipe, which ends downgradient of the dam. The pipe is placed 

perpendicular to and at the base of the water flow. In the pond, water accumulated until its level exceeds 

the height of the riser and the excess water discharges though the pipe to the downgradient outlet. The 

basin volume below the top of the riser is the sediment storage zone. The dam should be constructed of 

materials less permeable than gravel and clean sand. Local materials such as silty sand, clayey sand, and 

silt, are acceptable if they are free of debris. The storage volume may be increased by evacuation the area 

in from of the dam, and excavated materials may be used for the construction of the dam. The structure is 

provided with an emergency spillway to prevent water from flowing over the dam in flood conditions. 

The ratio between the basin length and width should be between 2:1 and 9:1. 

MP-15: Rock Filter 

Objective: Rock filters provide retention of runoff sediments, decrease runoff flow velocity and 

energy, and create physical boundaries for OHV’s. 

Explanation: A rock filter consists of a berm of crushed rock (size 1.5 to 3 inches), wrapped in poultry 

wire (one inch diameter hexagonal mesh, galvanized 20 gauge), and placed parallel to topographic 

contour lines on a horizontal surface at the toe of a slope. The purpose of the rock filter is to intercept 

sediment laden runoff from disturbed areas of the site, reduce flow velocity, promote sedimentation, and 

release the water as sheet flow. Rock filters are low cost and require low maintenance. 

MP-16: Gabion Mattresses 

Objective: To provide retention of runoff sediments, decrease runoff flow velocity and energy, and 

create a physical boundary for OHV’s. 

Explanation: A gabion mattress is a wire-mesh box filled with crushed rock. Typical mattress 

dimensions are: Height – six to nine inches; length – nine to twelve feet; and width – six feet. The 

purpose of gabion mattresses similar to that of the filter rock in which sediment laden runoff is 

intercepted from disturbed areas of the site, flow velocity is reduced sedimentation is promoted, and water 

is released as sheet flow. The main differences between mattresses and filter rock are: gabion mattresses 

may be placed on the slope before and after the slope break at the toe; gabion mattresses are more 

resilient; and mattresses are wider, resulting in better sediment trapping efficiency. 

C. Transportation & Roads 

MP-17: Dust Mitigation Measures 

Objective: Reduction of Chrysotile Emissions on Unpaved Roads and Trails 

Explanation: Airborne chrysotile dust would attempt to be controlled through various mitigating 

treatments. Treatments would potentially range from base rock, frequent application of water, 

Lignosulfonate, Calcium chloride, petroleum products, liquid copolymers and synthetic organic soil 

binding fluid. A variety of suppliers are available. Efficacy would need to be established through field

testing. Reapplication and maintenance schedules would be established through testing using 

manufacturers’ recommendation as baseline. Fugitive airborne dust and sloughing may increase 

application to subjective intervals. 

MP-18: Stream Course Protection 

Objective: (1) To protect the natural flow of streams, (2) to provide unobstructed passage of storm 

flows, (3) to reduce sediment and other pollutants from entering streams, and (4) to restore the natural 

course of any stream as soon as practicable if the stream is diverted as a result of management activities. 

Explanation: The following points are fundamental to protecting streams and stream courses: 

a. Vehicles should not operate within stream side management zones except where trails and roads 

cross the stream channel. 

b. Water bars and other erosion control structures will be located so as to prevent water and 

sediment from being channeled into stream courses and to dissipate concentrated flows. 

c. Material resulting from temporary road and ORV trail stream course crossing should be removed 

and stream banks restored and protected to the extent practicable. 

MP-19: Road Stream Crossings 

Objective: To ensure that roads do not unduly damage streams or disturb channels. 

Explanation: Culverts or other means are necessary on roads (temporary, semi-permanent, or 

permanent) at all locations where it is necessary to cross designated streams. Alternate means of crossing 

stream courses may include: rock fills, hardened fords (using such features as rocked approaches) and 

low water crossings. Most (if not all) crossings of perennial streams should be approved by an interdisciplinary team. Such facilities should be designed to provide for unobstructed flows and to minimize 

damages to stream courses. The number of crossings should be kept to the minimum needs for access. 

Channel crossings should be as perpendicular to stream courses as possible. Stream bank excavation 

should be kept to the minimum needed for use of the crossings, and entry and exit ramps may need to be 

rocked. Fords and turnpike crossings hardened with washed rock or landing mats are sometimes an 

acceptable alternative depending upon hydrological considerations. 

MP-20: Road Slope Design 

Objective: To reduce sedimentation by: (1) minimizing erosion from road slopes, and (2) 

minimizing the chances for slope failures along roads. 

Explanation: No stabilization project can entirely prevent erosion from cut and fill slopes, but no road 

construction should be planned without considering stabilization needs. The first planning requirement is 

for an adequate soil and geologic investigation, to provide data necessary for proper cut and fill design 

consideration such as: 

1) The proper cut and full slopes for the material; 

2) The handling of surface and subsurface drainage; 

3) Necessary compaction standards and surfacing needs.

A prerequisite for stabilization is to provide basic mechanical stability of the soils, using data from soils 

and geologic investigations to develop requirements for proper slope angles, compaction, and adequate 

drainage. 

MP-21: Road Slope Stabilization 

Objective: To improve road cut and fill slope stabilization by applying mechanical and vegetative 

measures. 

Explanation: Few slopes are sufficiently rocky to be naturally stable without needing additional 

measures. In most cases mechanical, and/or vegetative measures are required. Mechanical measures 

include but are not limited to: erosion nets, terraces, wattling, side drains, sub-surface dewater devices, 

blankets, fute mats, riprap, mulch, tackifier pavement, soil seals, and gunnite. Vegetative measures 

include the seeding of endemic herbaceous species (grass, legumes, or browse species) or the planting of 

endemic brush or trees. Vegetative measures may include: fertilization, mulching (or even watering) to 

insure success. A combination of endemic vegetative species often produces a better result than a more 

simplistic treatment, e.g., grass seeding alone. (See also MP – 5). 

MP-22: Dispersion of Subsurface Drainage from Cut and Fill Slopes. 

Objective: To minimize the possibilities of cut or fill slope failure and the subsequent production of 

sediment. 

Explanation: Roadways may drastically change the surface drainage characteristics of a slope. Since 

the angle and height of cut and fill slopes increase the risk of instability, it is often necessary to provide 

subsurface drainage to avoid moisture saturation necessary because of slopes, soil, aspect, and 

precipitation. Methods that should be used: 

1) Pipe under drains 

2) Horizontal drains 

3) Stabilization trenches 

Dispersion of collected water should be accomplished in an area capable of withstanding increased flows. 

On erosive soils, energy dissipaters need to be placed below pipe carrying large volumes of runoff water. 

MP-23: Control of Road Drainage 

Objective: (1) To minimize the erosive effects of water concentrated by road drainage features; (2) 

to disperse runoff from disturbances within the road clearing limits; (3) to lessen the sediment load from 

road areas; (4) to minimize erosion of the road prism by runoff from road surfaces and from uphill areas. 

Explanation: A number of measures can be used (alone or in combination) to control the detrimental 

effects of road drainage. Methods used to reduce erosion may include such things as properly spaced 

cross drains or water bars, dips, drop basins, energy dissipaters, aprons, downspouts, gabions, debris 

racks, and armoring of ditches and drain inlets and outlets. Disposal of runoff can be accomplished by 

such means as rolling the grade; out sloping; installation of water spreading ditches; contour trenching; or 

adequate sized over side drains, etc. Disposal of runoff also reduces peak down stream flows and 

associated high water erosion and sediment transport. Sediment loads can be reduced by installing such 

things as sediment filters, settling ponds, and contour trenches. Soil stabilization can help reduce 

sedimentation by lessening erosion on borrow and waste areas, on cut and fill slopes and on road 

shoulders.

MP-24: Erosion Control on OHV Routes. 

Objective: To protect water quality by minimizing erosion and sedimentation derived from OHV 

routes. 

Explanation: Installation of erosion control measures may be required on OHV routes. This work may 

involve cross ditches and water spreading ditches. Other methods such as back-blading may be used in 

lieu of cross drains. Volunteer groups may also be used for constructing erosion control structure 

projects. 

MP-25: Minimization of Sidecast Material. 

Objective: To minimize sediment production originating from material sidecast during road 

construction or maintenance. 

Explanation: Unconsolidated side-cast material is very difficult to stabilize and often such material is 

susceptible to erosion and / or mass instability. Sidecasting of un-compacted material should be 

permitted only at locations designated through interdisciplinary input, and shown in the plans. In some 

areas especially those slopes over 60 percent, end hauling may be the only acceptable alternative to 

sidecasting even though the costs are high and end-haul equipment may need certain minimum widths in 

which to work. Waste areas should be located where excess materials can be deposited and stabilized. 

During road maintenance operations, care should be taken to eliminate the deposition of sidecast material 

onto stabilized slopes. Disposal of slide debris should be done only at designated water areas. Personnel 

performing road maintenance should confine excavated or embankment material within the roadway 

limits and the roadway should be constructed in reasonably close conformity with the lines, grades, and 

dimensions designated on the ground. They should also remove materials deposited outside the roadway. 

All materials should be incorporated in the planned work. Disposal of excess excavation which develops 

due to miscalculation or a specific design change should be disposed of in a specified manner and at a 

specified location. 

MP-26: Maintenance of Roads 

Objective: To maintain roads in a manner which provides for water quality protection by minimizing 

rutting, failures, sidecasting, and blockage of drainage facilities – all of which can cause sedimentation 

and erosion. 

Explanation: Roads normally deteriorate because of use and weather impacts. This deterioration can 

be minimized through adequate maintenance and /or restriction of use. All system roads should be 

maintained to provide the basic custodial care required to protect the road investment and to see that 

damage to adjacent land and resources is held to a minimum. This level of maintenance often requires an 

annual inspection to determine what work, if any is needed to keep drainage functional and the road 

stable. This level is the normal prescription for roads that are closed or seasonally closed to traffic. As a 

minimum measure, maintenance must protect drainage facilities and runoff patterns. Higher levels of 

maintenance may be chosen to reflect greater use or resource administrative needs. Additional 

maintenance measures could include resurfacing, out sloping, clearing debris from dips and cross drains, 

armoring of ditches and spot rocking.

Record of Decision Resource Management Plan
 

Objective: (1) To reduce road surface disturbance and rutting of roads; and (2) to lessen sediment 

washing from disturbed road surfaces. 

Explanation: The use of many unimproved and semi-improved roads during wet weather often results 

in rutting and churning of the road surfaces. Run off from such disturbed road surfaces often carries a 

high sediment load. The damage/maintenance cycle for roads that are frequently used in winter can 

create a disturbed road surface that is a continuing sediment source. Roads that are used during wet 

periods should have a stable surface and/or sufficient drainage to allow such use with a minimum of 

resource impact. Rocking, oil, paving, and armoring are measures that may be necessary to protect the 

road surface and reduce material loss. Drainage should be maintained to prevent water from standing on 

the road surface or running down the road creating rills and gullies in the road surface. 

D. Abandoned Mine Lands & Mining Related Activities 

MP-28: Regulation of Streamside Gravel Borrow Areas 

Objective: To limit channel disturbances and sediment production associated with gravel source 

development. 

Explanation: Materials deposited along channel sections during storm runoff often provide an 

inexpensive source of gravel. Because of easy access this gravel is often in demand; with adequate 

planning, it can often be removed with minimal impact on water resources. Under some circumstances, 

gravel removal may alter stream flow characteristics and consequently affect stream channel stability and 

create a new sediment source. Borrowing should be limited to gravel bars above the water line which is 

normal for the period of excavation. If the borrow area is subject to periodic flooding, some leveling, 

shaping, or other special drainage features should be provided. Excavation should not take place below 

the water table unless sediment basins are built to contain or catch the resulting sediment. Sediment 

basins should not be subject to washouts. If excess sediment accumulates in basins, excavators should be 

required to clean the basin and deposit removed sediment in approved sites. Serpentine areas should not 

be used as a gravel source for use outside of the serpentine area. 

MP-29: Restoration of Borrow Pits, Quarries, and Mining Operations 

Objectives: To minimize sediment production from borrow pits, quarry sites and mining operations. 

Explanation: Borrow pits, quarries, and mining operations are often susceptible to erosion due to steel 

side slopes, lack of vegetation, and/or their proximity to water courses. Whenever necessary, prior 

excavation of the site, top soil should be removed and stockpiled for surface dressing in the post operation 

rehabilitation period. Once excavation has been completed on all or part of the area, the sides will be 

sloped and graded and the general pit area smoothed and stabilized. Oversize material, if left in the pit or 

quarry, should be evenly distributed. Finer materials should be spread over the bottom of the pit prior to 

spreading stockpiled or imported top soil. Seeding and mulching may be required and sediment basins 

should also be considered. Access roads to the site should be ripped, drained, blocked to traffic, and 

seeded unless other treatment is required by the design. 

MP-30: Environmental Health and Safety Hazard Awareness 

Objective: Improve the level of visitor awareness of environmental health and safety hazards, e.g., 

hazardous airborne asbestos fibers.

Explanation: The public will be encouraged through signs, pamphlets, media exposure and public 

contact to minimize and reduce exposure to environmental hazards. 

E. Recreation Facilities 

MP-31: Surface erosion Control at Facility Sites 

Objective: Limit the amount of surface erosion taking place on developed sites and the amount of 

soil entering streams. 

Explanation: On lands developed for campgrounds, parking areas or waste disposal sites much ground 

is cleared of vegetation. Erosion control methods need to be implemented to keep as much of the oils in 

place as possible and to reduce the amount of soil entering streams Some examples of erosion control 

methods that can be applied at a site for keeping the soil in place would be applying endemic species 

seed, jute matting, tackifiers, hydro mulch, paving or rocking of roads, water bars, cross drains, or 

retaining walls. To control the amount of soil entering streams, the natural drainage pattern of the area 

should not be changed. Sediment basins and sediment filters should be established to filter surface runoff. 

Diversion ditches and berms should be built to divert surface runoff around bare areas. Construction 

activities should be scheduled to avoid periods of the year when heavy runoff will occur. 

MP-32: Control of Sanitation Facilities. 

Objective: To protect surface and subsurface water quality from bacteria, nutrients, and chemical 

pollutants resulting from collection, transmission, and disposal of sewage from Bureau of Land 

Management facilities. 

Explanation: Toilet facilities are provided at semi-developed and developed recreation sites. 

Sanitation facilities will be planned, located, designed, constructed, operated, inspected and maintained to 

minimize the possibility of water contamination. Toilet facilities should be located outside of the flood 

plain. 

MP-33 Control of Refuse Disposal 

Objective: To protect water quality from nutrients, bacteria, and chemicals associated with solid 

waste disposal. 

Explanation: Users of public land recreation facilities are encouraged cooperate in the proper disposal 

of garbage and trash. Receptacles are provided at most semi-developed sites. Garbage and trash must be 

packed out by those who use dispersed areas. The final disposal of collected garbage will be at a proper 

designated and operated sanitary landfill. The land fill site will be located where groundwater and surface 

waters are at safe distances as prescribed by State or local Health Board regulations.

Appendix VI - Wild & Scenic River Inventory
 

Wild and Scenic River System 

The Wild and Scenic Rivers Act of 1968 (Public Law 90-542) was passed by Congress to preserve 

riverine systems that contain outstanding features. The law was enacted during an era when many rivers 

were being dammed or diverted, and is intended to balance this development by ensuring that certain 

rivers and streams remain in their free-flowing condition. The BLM is mandated to evaluate stream 

segments on public lands as potential additions to the National Wild and Scenic Rivers System (NWSRS) 

during the Resource Management Plan (RMP) process under Section 5(d) of the Act. The NWSRS study 

guidelines are found in BLM Manual 8351, U.S. Departments of Agriculture and Interior Guidelines 

published in Federal Register Vol. 7, No.173, September 7, 1982 and in various BLM memoranda and 

policy statements. Formal designation as a Wild and Scenic River requires Congressional Legislation, or 

designation can be approved by the Secretary of Interior if nominated by the Governor of the state 

containing the river segment. The following discussion provides information on how BLM considered 

waterways for potential inclusion in the NWSRS. 

The NWSRS study process has three distinct steps: 

1.	 Determine what rivers or river segments are eligible for NWSRS designation; 

2.	 Determine the potential classification of eligible river segments as wild, scenic, recreational 

or any combination thereof; and 

3.	 Conduct a suitability study to determine if the river segments are suitable for designation as 

components of the NWSRS. 

This report documents all three steps of the process for the streams in the planning area. 

Eligibility of Planning Area Rivers & Streams 

Identification 

A variety of sources were reviewed to identify waterways which could have potential for wild and scenic 

river designation. They include the Nationwide Rivers Inventory List, the Outstanding Rivers List 

compiled by American Rivers, Inc., river segments identified by state or local government, river segments 

identified by the public during formulation of the CCMA RMP/EIS, and river segments identified by the 

planning team as having potential to meet Wild and Scenic River eligibility requirements. 

The Wild and Scenic Rivers Act defines a river as a “flowing body of water or estuary or a section, 

portion, or tributary thereof, including rivers, streams, creeks, runs, kills, rills, and small lakes.” 

Eleven stream segments totaling 21 miles located on or crossing BLM public lands were identified for 

review. These streams segments are identified on Map 7 in Appendix I and are listed in Table 1 below.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

Eligibility Determination 

Each identified river segment was evaluated to determine whether it is eligible for inclusion in the 

NWSRS. To be eligible, a river segment must be “free flowing” and must possess at least one 

“outstandingly remarkable value” (ORV). These ORV’s include: 

1) Scenic, 7) Cultural, 

2) Recreational, 8) Ecological, 

3) Geological, 9) Riparian, 

4) Fish, 10) Botanical, 

5) Wildlife, 11) Hydrological, and 

6) Historical, 12) Scientific values 

To be considered as “outstandingly remarkable”, a river related value must be a unique, rare, or 

exemplary feature that is significant at a comparative regional or national scale. Only one such value is 

needed for eligibility. All values should be directly river related, meaning they should: 

1) Be located in the river or on its immediate shorelands (generally within 1⁄4 mile on either side of 

the river); 

2) Contribute substantially to the functioning of the river ecosystem; and/or 

3) Owe their location or existence to the presence of the river. 

These are the only factors considered in determining the eligibility of a river segment. All other relevant 

factors are considered in determining suitability. A river need not be navigable by watercraft to be 

eligible. For purposes of eligibility determination, the volume of flow is sufficient if it is enough to 

maintain the outstandingly remarkable value(s) identified within the segment. 

Table 1 summarizes the eligibility evaluation of all identified river segments. The table includes 

information on the length of stream segments managed by BLM, free-flowing status, and outstandingly 

remarkable value(s) of each eligible segment, if applicable. Table 1 also gives a description of each 

eligible river segment’s location on BLM Surface Management (SM) maps.

Record of Decision & Approved RMP 

Suitability of Hollister Field Office Stream Segments 

All river segments identified on Map 7 in Appendix I and displayed in Table 1 (above) were found to be 

eligible for inclusion into the NWSRS. 

Section 4(a) of the Wild and Scenic River Act mandates that all rivers found eligible as potential 

additions to the NWSRS be studied as to their suitability for such a designation. The purpose of the 

suitability study is to provide information upon which the President of the United States can base his 

recommendation and Congress can make a decision. The study report describes the characteristics that do 

or do not make the stream segment a worthy addition to the system, the current status of land ownership 

and use in the area, the reasonably foreseeable potential uses of the land and water which would be 

enhanced, foreclosed, or curtailed if the area were included in the system, and several other factors. The 

suitability study is designed to answer these questions: 

 Should the river’s free–flowing character, water quality, and outstandingly remarkable values 

(ORVs) be protected, or are one or more other uses important enough to warrant doing otherwise? 

 Will the river’s free-flowing character, water quality, and ORVs be protected through 

designation? Is it the best method for protecting the river corridor? 

 Is there a demonstrated commitment to protect the river by any nonfederal entities that may be 

partially responsible for implementing protective management? 

Pursuant to Sections 4(a) and 5(c) of the Wild and Scenic Rivers Act, the following factors would be 

considered and evaluated as a basis for the suitability determination for each river (as described further, 

below); 

a.	 Characteristics that do or do not make the area a worthy addition to the NWSRS; 

b.	 The current status of land ownership, minerals (surface and subsurface), and use in the area, 

including the amount of private land involved and associated or incompatible uses. 

c.	 The reasonably foreseeable potential uses of the land and water that would be enhanced, 

foreclosed, or curtailed if the area were included in the NWSRS. Historical or existing rights 

which could be adversely affected. 

d.	 The federal agency that will administer the area should it be added to the NWSRS. 

e.	 The estimated cost to the United States of acquiring necessary lands and interests in lands and of 

administering the area should it be added to the NWSRS. 

f.	 A determination of the degree to which the state or its political subdivisions might participate in 

the preservation and administration of the river should it be proposed for inclusion in the 

NWSRS. 

g.	 An evaluation of the adequacy of local zoning and other land use controls in protecting the river’s 

ORVs by preventing incompatible development; 

h.	 Federal, public, state, local, or other interests in designation or non-designation of the river, 

including the extent to which the administration of the river, including the cost thereof, may be 

shared by state, local, or other agencies and individuals. Support or opposition to the designation. 

i.	 The consistency of designation with other agency plans, programs or policies and in meeting 

regional objectives. 

j.	 The contribution to river system or basin integrity. 

k.	 The ability of BLM to manage the river segments under designation, or ability to protect the river 

area other than Wild and Scenic designation.

Clear Creek Management Area Appendix VI 

Record of Decision & Approved RMP 

1. Characteristics that Do or Do Not Make the River Segments Worthy Additions to the NWSRS 

Stream segments in the Planning Area are located within the California Coast Ranges of the Pacific 

Border Physiographic Province. This province was used as a basis to determine if the study segments 

possess characteristics of at least regional significance that would make them worthy additions to the 

NWSRS. The Pacific Border province contains the highest rainfall and density of streams in California. 

Also, many of these streams provide habitat for anadromous fisheries. 

The San Francisco Bay and Central Coast portion of the Coast Ranges are considered a distinct 

hydrological area because precipitation in this region is generally about 50% of that in the northern part of 

the province and snowmelt influences are insignificant. The tectonics associated with the San Andreas 

Fault system have influenced the orientation and location of the major river valleys. Sediment yields are 

high because of high-intensity rainfall, high rates of uplift, and unstable rocks. These small steep 

watersheds have short lag times and high peak runoffs, and rivers often flood during winter storms. 

During this inventory, BLM identified 15 designated National Wild & Scenic Rivers in California, which 

include portions of the North Fork and Lower American River, Big Sur River, Black Butte River, Eel 

River, Feather River, King River, Kern River. Klamath River, Merced River, Sespe Creek, Sisquoc River, 

Smith River, Trinity River, and Tuolumne River. This amounts to more than 1,800 miles of rivers and 

streams that are designated as part of the NWSRS in California. 

Many of the eligible river segments within the CCMA have outstandingly remarkable values when 

considered in the context of other streams in the region. However, the BLM planning team found that all 

river segments provided below-average to low quality values in the statewide and national context. 

Therefore, they are not considered to be worthy additions to the system. 

In summary, although these values meet the minimum eligibility criteria, when viewed in the context of 

the California Coast Ranges of the Pacific Border Physiographic Province, the study team determined that 

these river segments were not of a level of quality to make them worthy additions to the NWSRS. 

2. Status of Land Ownership and Current Use 

BLM Manual 8351.33A(2), “Wild and Scenic Rivers – Policy and Program Direction for Identification, 

Evaluation and Management”, states “In situations where there is limited public land (shoreline and 

adjacent land) administered by the BLM within an identified river study area, it may be difficult to ensure 

those identified outstandingly remarkable values could be properly maintained and afforded adequate 

management protection over time. Accordingly, for those situations where the BLM is unable to protect 

or maintain any identified outstandingly remarkable values, or through other mechanisms (existing or 

potential), river segments may be determined suitable only if the entity with land use planning 

responsibility supports the finding and commits to assisting the BLM in protecting the identified river 

values. An alternative method to consider these segments is for state, local governments or private 

citizens to initiate efforts under section 2(a)(ii), or a joint study under section 5C of the Wild and Scenic 

Rivers Act.” Typically, the local county governments have land use planning responsibility for the private 

lands on these segments. However, BLM has not approached the counties in the Planning Area regarding 

their support for wild and scenic designation of these segments, because the study team determined that 

they are not worthy additions to the system and BLM ownership of shoreline and adjacent lands is 

sufficient to ensure that ORVs could be properly maintained and afforded adequate management 

protection over time regardless of designation. 

3. Potential Uses of the Land to be Enhanced or Curtailed by Designation/ Historical or Existing 

Rights That Could Be Adversely Affected, including Water Resources Projects. 

Diversion of additional water from any of the streams during the summer low-flow period could impact 

outstandingly remarkable values if they are present. Wild and Scenic River designation would not impact 

current water rights, but could affect future diversions from the streams.

4. Federal Agency that will Administer Wild & Scenic River Segments 

BLM’s Hollister Field Office would administer all river segments under evaluation should they be 

included in the NWSRS. 

5. Estimated Cost of Acquisition and Administration 

There would be a minor need to acquire additional lands for Hollister Field Office river segments to be 

included in the National Wild & Scenic River System. A small number of private in-holdings and CCMA 

adjacent lands would need to be acquired (or placed under conservation easements) in stream corridors to 

maintain or restore their character. There would also be a modest cost associated with developing 

management plan(s) for all designated streams, and coordination with mining claim holders and private 

landowners to ensure that their activities would not cause offsite (downstream or downslope) impacts that 

could potentially affect river values. 

6. State or local political subdivision participation in river preservation and management. 

During the initial scoping period no government agencies commented or expressed interest specifically in 

wild and scenic river designation. However, numerous state and Federal agencies are committed to 

protecting river related values on the study segments. For example, the BLM and California State Parks 

OHV Division have funded grants to reduce sediment transport that result from watershed management 

activities in the CCMA. Plus, BLM is working with Regional Water Quality Control Districts and EPA to implement total 

maximum daily loads (TMDLs) for pollutants in San Benito River (mercury, sediment) and Clear Creek (sediment). In 

summary, there is already a strong established level of cooperation among Federal, state and local 

agencies to restore and protect the beneficial uses of streams in the region. 

7. Local Zoning and Land Use Planning Adequacy in protecting the river values. 

All of the stream segments included in this study are on Federal Lands administered by the BLM and 

local zoning would not apply. Where the segments cross private lands, most stretches are zoned for 

livestock, agriculture, or residential use. Livestock and agricultural uses at the scales foreseen within the 

study segments would not be compatible with Wild and Scenic River designation. Although the private 

land base in these watersheds could be developed for residences, it is likely to be low density and retain 

its rural character, which would be compatible with Wild and Scenic River designation. 

8. Federal, public, state, local or other interests in designation/non-designation of the river. Support 

or Opposition to the Designation. 

A description of other Federal, state and local agency involvement and interest in river management is 

contained under item 6 above. Residents of the San Joaquin Valley and Hernandez Valley have a long 

history of active interest in water conservation for flood control and agriculture or livestock use. Although 

no comments specific to wild and scenic river designation were received during the scoping period, many 

comments were received regarding protection of river related values including water quality/quantity, 

riparian habitat, recreation opportunities, and scenic values. 

9. The consistency of designation with other agency plans, programs or policies and in meeting 

regional objectives. 

Wild and Scenic River designation for most of the study segments would be consistent with BLM’s goals 

for natural and cultural resources and other agency plans and programs for the region. However, wild and 

scenic river management and promoting recreational activities on the CCMA river segments in the 

Serpentine ACEC would not be consistent with BLM and EPA goals to provide adequate protection of 

human health and the environment. 

10. Contribution to River System or Basin Integrity 

The contribution of wild and scenic river designation to river system or basin integrity in the planning 

area would be minimal due to the current regulations and existing efforts to conserve water resources for 

beneficial uses.

11. Management or Protection other than Wild and Scenic River Designation 

In the case of river segments that are found not suitable for designation, the Hollister Field Office will 

continue to manage these streams as integral ecosystem components on BLM public lands. Management 

objectives in this RMP/EIS call for continued emphasis on restoration of riparian ecosystems, and other 

components of healthy watersheds. The preferred alternative for this plan also calls for the BLM to 

submit applications to the State of California for federal water reserves to protect the aquatic habitat of 

streams on public lands. 

Recommendation and Rationale - It is recommended that none of the eligible river segments identified 

in this study, as defined in Table 1, be designated as components of the NWSRS. Many of the river 

segments under evaluation have similar land tenure status, historical uses, and potential or existing uses. 

The primary factor for the non-suitable determination of all river study segments in the planning area was 

the conclusion that they would not make worthy additions to the system. Many of these watersheds have 

been substantially modified through past mining and logging activities and the associated construction of 

roads and trails. The resulting landscapes would not broaden the representation of key ecosystems within 

the Wild and Scenic River system. A second factor contributed to the non-suitable recommendation for 

river segments in the Tucker Zone. Although these watersheds are currently somewhat undeveloped, local 

and regional planning may consider development in these areas to address California’s growing 

population. The anticipated level of development is not likely to change the character of the watersheds or 

be incompatible with Wild and Scenic River designation. Biological resources and other watershed values 

for all streams will be afforded protection through state and local land use plans, the Clean Water Act, and 

the Endangered Species Act. 

Protective Management 

All river segments found to be eligible for inclusion in the NWSRS are placed under protective 

management by the BLM. Subject to valid existing rights, the BLM is required to protect the free-flowing 

characteristics and outstandingly remarkable values in the stream corridors. The BLM must also protect 

the corridor from modifications that would impact the tentative river classification (i.e. change the 

classification potential from Wild to Scenic, or from Scenic to Recreational). These management 

restrictions apply only to public lands. Once suitability is determined and the Record of Decision (ROD) 

for the RMP signed, protective management continues only for those segments found suitable for 

designation. This protective management remains in effect until Congress makes a final decision 

regarding designation, or the CCMA RMP is amended.

Appendix VII - Best Management Practices for Wind Energy 

Development on Public Lands 

The following Best Management Practices (BMPs) will be applied to all wind energy development 

projects to establish environmentally sound and economically feasible mechanisms to protect and enhance 

natural and cultural resources. These proposed BMPs were derived from the mitigation measures 

discussed in Chapter 5 of the Programmatic Environmental Impact Statement (PEIS) but are limited to 

those measures that are applicable to all wind energy development projects (PEIS Section 5.15). These 

BMPs would be adopted as required elements of project-specific PODs and/or as ROW authorization 

stipulations. They are categorized by development activity: site monitoring and testing, development of 

the POD, construction, operation, and decommissioning. The proposed BMPs for development of the 

POD identify required elements of the POD needed to address potential impacts associated with 

subsequent phases of development. 

Some of the proposed BMPs address issues that are not unique to wind energy development but that are 

more universal in nature, such as road construction and maintenance, wildlife management, hazardous 

materials and waste management, cultural resource management, and pesticide use and integrated pest 

management. For the most part, however, the level of detail provided by the BMPs is less specific than 

that provided in other, existing BLM program-specific mitigation guidance documents (PEIS Section 

3.6.2). As required by proposed policy (PEIS Section 2.2.3.1), mitigation measures identified in or 

required by these existing program-specific guidance documents would be applied, as appropriate, to 

wind energy development projects; however, they are not discussed in detail in the programmatic BMPs 

proposed here. 

In summary, stipulations governing specific wind energy projects would be derived from a number of 

sources: (1) the proposed BMPs discussed in this section; (2) other, existing and relevant programspecific mitigation guidance (PEIS Section 3.6); and (3) the mitigation measures discussed in PEIS 

Chapter 5. Guidelines for applying and selecting project-specific requirements include determining 

whether the measure would (1) ensure compliance with relevant statutory or administrative requirements, 

(2) minimize local impacts associated with siting and design decisions, (3) promote post-construction 

stabilization of impacts, (4) maximize restoration of previous habitat conditions, (5) minimize cumulative 

impacts, or (6) promote economically feasible development of wind energy on BLM-administered land. 

Site Monitoring and Testing 

1. The area disturbed by installation of meteorological towers (i.e., footprint) shall be kept to a 

minimum. 

2.	 Existing roads shall be used to the maximum extent feasible. If new roads are necessary, they 

shall be designed and constructed to the appropriate standard. 

3.	 Meteorological towers shall not be located in sensitive habitats or in areas where ecological 

resources known to be sensitive to human activities (e.g., prairie grouse) are present. Installation 

of towers shall be scheduled to avoid disruption of wildlife reproductive activities or other 

important behaviors. 

4.	 Meteorological towers installed for site monitoring and testing shall be inspected periodically for 

structural integrity.

Plan of Development Preparation 

General 

1.	 The BLM and operators shall contact appropriate agencies, property owners, and other 

stakeholders early in the planning process to identify potentially sensitive land uses and issues, 

rules that govern wind energy development locally, and land use concerns specific to the region. 

2.	 Available information describing the environmental and sociocultural conditions in the vicinity of 

the proposed project shall be collected and reviewed as needed to predict potential impacts of the 

project. 

3.	 The Federal Aviation Administration (FAA)-required notice of proposed construction shall be 

made as early as possible to identify any air safety measures that would be required. 

4.	 To plan for efficient use of the land, necessary infrastructure requirements shall be consolidated 

wherever possible, and current transmission and market access shall be evaluated carefully. 

5.	 The project shall be planned to utilize existing roads and utility corridors to the maximum extent 

feasible, and to minimize the number and length/size of new roads, lay-down areas, and borrow 

areas. 

6.	 A monitoring program shall be developed to ensure that environmental conditions are monitored 

during the construction, operation, and decommissioning phases. The monitoring program 

requirements, including adaptive management strategies, shall be established at the project level 

to ensure that potential adverse impacts of wind energy development are mitigated. The 

monitoring program shall identify the monitoring requirements for each environmental resource 

present at the site, establish metrics against which monitoring observations can be measured, 

identify potential mitigation measures, and establish protocols for incorporating monitoring 

observations and additional mitigation measures into standard operating procedures and BMPs. 

7.	 “Good housekeeping” procedures shall be developed to ensure that during operation the site will 

be kept clean of debris, garbage, fugitive trash or waste, and graffiti; to prohibit scrap heaps and 

dumps; and to minimize storage yards. 

Wildlife and Other Ecological Resources 

1.	 Operators shall review existing information on species and habitats in the vicinity of the project 

area to identify potential concerns. 

2.	 Operators shall conduct surveys for federal- and/or state-protected species and other species of 

concern (including special status plant and animal species) within the project area and design the 

project to avoid (if possible), minimize, or mitigate impacts to these resources. 

3.	 Operators shall identify important, sensitive, or unique habitats in the vicinity of the project and 

design the project to avoid (if possible), minimize, or mitigate impacts to these habitats (e.g., 

locate the turbines, roads, and ancillary facilities in the least environmentally sensitive areas; i.e., 

away from riparian habitats, streams, wetlands, drainages, or critical wildlife habitats). 

4.	 The BLM will prohibit the disturbance of any population of federal listed plant species. 

5.	 Operators shall evaluate avian and bat use of the project area and design the project to minimize 

or mitigate the potential for bird and bat strikes (e.g., development shall not occur in riparian 

habitats and wetlands). Scientifically rigorous avian and bat use surveys shall be conducted; the 

amount and extent of ecological baseline data required shall be determined on a project basis. 

6.	 Turbines shall be configured to avoid landscape features known to attract raptors, if site studies 

show that placing turbines there would pose a significant risk to raptors. 

7.	 Operators shall determine the presence of bat colonies and avoid placing turbines near known bat 

hibernation, breeding, and maternity/nursery colonies; in known migration corridors; or in known 

flight paths between colonies and feeding areas.

Record of Decision Resource Management Plan
 

8.	 Operators shall determine the presence of active raptor nests (i.e., raptor nests used during the 

breeding season). Measures to reduce raptor use at a project site (e.g., minimize road cuts, 

maintain either no vegetation or nonattractive plant species around the turbines) shall be 

considered. 

9.	 A habitat restoration plan shall be developed to avoid (if possible), minimize, or mitigate negative 

impacts on vulnerable wildlife while maintaining or enhancing habitat values for other species. 

The plan shall identify revegetation, soil stabilization, and erosion reduction measures that shall 

be implemented to ensure that all temporary use areas are restored. The plan shall require that 

restoration occur as soon as possible after completion of activities to reduce the amount of habitat 

converted at any one time and to speed up the recovery to natural habitats. 

10. Procedures shall be developed to mitigate potential impacts to special status species. Such 

measures could include avoidance, relocation of project facilities or lay-down areas, and/or 

relocation of biota. 

11. Facilities shall be designed to discourage their use as perching or nesting substrates by birds. For 

example, power lines and poles shall be configured to minimize raptor electrocutions and 

discourage raptor and raven nesting and perching. 

Visual Resources 

1.	 The public shall be involved and informed about the visual site design elements of the proposed 

wind energy facilities. Possible approaches include conducting public forums for disseminating 

information, offering organized tours of operating wind developments, and using computer 

simulation and visualization techniques in public presentations. 

2.	 Turbine arrays and turbine design shall be integrated with the surrounding landscape. Design 

elements to be addressed include visual uniformity, use of tubular towers, proportion and color of 

turbines, nonreflective paints, and prohibition of commercial messages on turbines. 

3.	 Other site design elements shall be integrated with the surrounding landscape. Elements to 

address include minimizing the profile of the ancillary structures, burial of cables, prohibition of 

commercial symbols, and lighting. Regarding lighting, efforts shall be made to minimize the need 

for and amount of lighting on ancillary structures. 

Roads 

1.	 An access road siting and management plan shall be prepared incorporating existing BLM 

standards regarding road design, construction, and maintenance such as those described in the 

BLM 9113 Manual (BLM 1985) and the Surface Operating Standards for Oil and Gas 

Exploration and Development (RMRCC 1989) (i.e., the Gold Book). 

Ground Transportation 

1.	 A transportation plan shall be developed, particularly for the transport of turbine components, 

main assembly cranes, and other large pieces of equipment. The plan shall consider specific 

object sizes, weights, origin, destination, and unique handling requirements and shall evaluate 

alternative transportation approaches. In addition, the process to be used to comply with unique 

state requirements and to obtain all necessary permits shall be clearly identified. 

2.	 A traffic management plan shall be prepared for the site access roads to ensure that no hazards 

would result from the increased truck traffic and that traffic flow would not be adversely 

impacted. This plan shall incorporate measures such as informational signs, flaggers when 

equipment may result in blocked throughways, and traffic cones to identify any necessary 

changes in temporary lane configuration.

Noise 

1.	 Proponents of a wind energy development project shall take measurements to assess the existing 

background noise levels at a given site and compare them with the anticipated noise levels 

associated with the proposed project. 

Noxious Weeds and Pesticides 

1.	 Operators shall develop a plan for control of noxious weeds and invasive species, which could 

occur as a result of new surface disturbance activities at the site. The plan shall address 

monitoring, education of personnel on weed identification, the manner in which weeds spread, 

and methods for treating infestations. The use of certified weed-free mulching shall be required. 

If trucks and construction equipment are arriving from locations with known invasive vegetation 

problems, a controlled inspection and cleaning area shall be established to visually inspect 

construction equipment arriving at the project area and to remove and collect seeds that may be 

adhering to tires and other equipment surfaces. 

2.	 If pesticides are used on the site, an integrated pest management plan shall be developed to ensure 

that applications would be conducted within the framework of BLM and DOI policies and entail 

only the use of EPA-registered pesticides. Pesticide use shall be limited to nonpersistent, 

immobile pesticides and shall only be applied in accordance with label and application permit 

directions and stipulations for terrestrial and aquatic applications. 

Cultural/Historic Resources 

1.	 The BLM will consult with Indian Tribal governments early in the planning process to identify 

issues regarding the proposed wind energy development, including issues related to the presence 

of cultural properties, access rights, disruption to traditional cultural practices, and impacts to 

visual resources important to the Tribe(s). 

2.	 The presence of archaeological sites and historic properties in the area of potential effect shall be 

determined on the basis of a records search of recorded sites and properties in the area and/or, 

depending on the extent and reliability of existing information, an archaeological survey. 

Archaeological sites and historic properties present in the area of potential effect shall be 

reviewed to determine whether they meet the criteria of eligibility for listing on the National 

Register of Historic Places (NRHP). 

3.	 When any ROW application includes remnants of a National Historic Trail, is located within the 

viewshed of a National Historic Trail’s designated centerline, or includes or is within the 

viewshed of a trail eligible for listing on the NRHP, the operator shall evaluate the potential 

visual impacts to the trail associated with the proposed project and identify appropriate mitigation 

measures for inclusion as stipulations in the POD. 

4.	 If cultural resources are present at the site, or if areas with a high potential to contain cultural 

material have been identified, a cultural resources management plan (CRMP) shall be developed. 

This plan shall address mitigation activities to be taken for cultural resources found at the site. 

Avoidance of the area is always the preferred mitigation option. Other mitigation options include 

archaeological survey and excavation (as warranted) and monitoring. If an area exhibits a high 

potential, but no artifacts were observed during an archaeological survey, monitoring by a 

qualified archaeologist could be required during all excavation and earthmoving in the highpotential area. A report shall be prepared documenting these activities. The CRMP also shall (1) 

establish a monitoring program, (2) identify measures to prevent potential looting/vandalism or 

erosion impacts, and (3) address the education of workers and the public to make them aware of 

the consequences of unauthorized collection of artifacts and destruction of property on public 

land.

Record of Decision Resource Management Plan
 

Paleontological Resources 

1.	 Operators shall determine whether paleontological resources exist in a project area on the basis of 

the sedimentary context of the area, a records search for past paleontological finds in the area, 

and/or, depending on the extent of existing information, a paleontological survey. 

2.	 If paleontological resources are present at the site, or if areas with a high potential to contain 

paleontological material have been identified, a paleontological resources management plan shall 

be developed. This plan shall include a mitigation plan for collection of the fossils; mitigation 

could include avoidance, removal of fossils, or monitoring. If an area exhibits a high potential but 

no fossils were observed during survey, monitoring by a qualified paleontologist could be 

required during all excavation and earthmoving in the sensitive area. A report shall be prepared 

documenting these activities. The paleontological resources management plan also shall (1) 

establish a monitoring program, (2) identify measures to prevent potential looting/vandalism or 

erosion impacts, and (3) address the education of workers and the public to make them aware of 

the consequences of unauthorized collection of fossils on public land. 

Hazardous Materials and Waste Management 

1.	 Operators shall develop a hazardous materials management plan addressing storage, use, 

transportation, and disposal of each hazardous material anticipated to be used at the site. The plan 

shall identify all hazardous materials that would be used, stored, or transported at the site. It shall 

establish inspection procedures, storage requirements, storage quantity limits, inventory control, 

nonhazardous product substitutes, and disposition of excess materials. The plan shall also identify 

requirements for notices to federal and local emergency response authorities and include 

emergency response plans. 

2.	 Operators shall develop a waste management plan identifying the waste streams that are expected 

to be generated at the site and addressing hazardous waste determination procedures, waste 

storage locations, waste-specific management and disposal requirements, inspection procedures, 

and waste minimization procedures. This plan shall address all solid and liquid wastes that may 

be generated at the site. 

3.	 Operators shall develop a spill prevention and response plan identifying where hazardous 

materials and wastes are stored on site, spill prevention measures to be implemented, training 

requirements, appropriate spill response actions for each material or waste, the locations of spill 

response kits on site, a procedure for ensuring that the spill response kits are adequately stocked 

at all times, and procedures for making timely notifications to authorities. 

Storm Water 

1.	 Operators shall develop a storm water management plan for the site to ensure compliance with 

applicable regulations and prevent off-site migration of contaminated storm water or increased 

soil erosion. 

Human Health and Safety 

1.	 A safety assessment shall be conducted to describe potential safety issues and the means that 

would be taken to mitigate them, including issues such as site access, construction, safe work 

practices, security, heavy equipment transportation, traffic management, emergency procedures, 

and fire control. 

2.	 A health and safety program shall be developed to protect both workers and the general public 

during construction, operation, and decommissioning of a wind energy project. Regarding 

occupational health and safety, the program shall identify all applicable federal and state

occupational safety standards; establish safe work practices for each task (e.g., requirements for 

personal protective equipment and safety harnesses; Occupational Safety and Health 

Administration [OSHA] standard practices for safe use of explosives and blasting agents; and 

measures for reducing occupational electric and magnetic fields [EMF] exposures); establish fire 

safety evacuation procedures; and define safety performance standards (e.g., electrical system 

standards and lightning protection standards). The program shall include a training program to 

identify hazard training requirements for workers for each task and establish procedures for 

providing required training to all workers. Documentation of training and a mechanism for 

reporting serious accidents to appropriate agencies shall be established. 

3.	 Regarding public health and safety, the health and safety program shall establish a safety zone or 

setback for wind turbine generators from residences and occupied buildings, roads, ROWs, and 

other public access areas that is sufficient to prevent accidents resulting from the operation of 

wind turbine generators. It shall identify requirements for temporary fencing around staging 

areas, storage yards, and excavations during construction or decommissioning activities. It shall 

also identify measures to be taken during the operation phase to limit public access to hazardous 

facilities (e.g., permanent fencing would be installed only around electrical substations, and 

turbine tower access doors would be locked). 

4.	 Operators shall consult with local planning authorities regarding increased traffic during the 

construction phase, including an assessment of the number of vehicles per day, their size, and 

type. Specific issues of concern (e.g., location of school bus routes and stops) shall be identified 

and addressed in the traffic management plan. 

5.	 If operation of the wind turbines is expected to cause significant adverse impacts to nearby 

residences and occupied buildings from shadow flicker, low-frequency sound, or EMF, sitespecific recommendations for addressing these concerns shall be incorporated into the project 

design (e.g., establishing a sufficient setback from turbines). 

6.	 The project shall be planned to minimize electromagnetic interference (EMI) (e.g., impacts to 

radar, microwave, television, and radio transmissions) and comply with Federal Communications 

Commission [FCC] regulations. Signal strength studies shall be conducted when proposed 

locations have the potential to impact transmissions. Potential interference with public safety 

communication systems (e.g., radio traffic related to emergency activities) shall be avoided. 

7.	 The project shall be planned to comply with FAA regulations, including lighting regulations, and 

to avoid potential safety issues associated with proximity to airports, military bases or training 

areas, or landing strips. 

8.	 Operators shall develop a fire management strategy to implement measures to minimize the 

potential for a human-caused fire. 

Construction 

General 

1.	 All control and mitigation measures established for the project in the POD and the resourcespecific management plans that are part of the POD shall be maintained and implemented 

throughout the construction phase, as appropriate. 

2.	 The area disturbed by construction and operation of a wind energy development project (i.e., 

footprint) shall be kept to a minimum. 

3.	 The number and size/length of roads, temporary fences, lay-down areas, and borrow areas shall 

be minimized. 

4.	 Topsoil from all excavations and construction activities shall be salvaged and reapplied during 

reclamation.

6.	 All electrical collector lines shall be buried in a manner that minimizes additional surface 

disturbance (e.g., along roads or other paths of surface disturbance). Overhead lines may be used 

in cases where burial of lines would result in further habitat disturbance. 

7.	 Operators shall identify unstable slopes and local factors that can induce slope instability (such as 

groundwater conditions, precipitation, earthquake activities, slope angles, and the dip angles of 

geologic strata). Operators also shall avoid creating excessive slopes during excavation and 

blasting operations. Special construction techniques shall be used where applicable in areas of 

steep slopes, erodible soil, and stream channel crossings. 

8.	 Erosion controls that comply with county, state, and federal standards shall be applied. Practices 

such as jute netting, silt fences, and check dams shall be applied near disturbed areas. 

Wildlife 

1.	 Guy wires on permanent meteorological towers shall be avoided.

after completion of construction activities to reduce the amount of habitat converted at any one 

time and to speed up the recovery to natural habitats. 

3.	 All construction employees shall be instructed to avoid harassment and disturbance of wildlife, 

especially during reproductive (e.g., courtship and nesting) seasons. In addition, pets shall not be 

permitted on site during construction. 

Visual Resources 

1.	 Operators shall reduce visual impacts during construction by minimizing areas of surface 

disturbance, controlling erosion, using dust suppression techniques, and restoring exposed soils as 

closely as possible to their original contour and vegetation. 

Roads 

1.	 Existing roads shall be used, but only if in safe and environmentally sound locations. If new roads 

are necessary, they shall be designed and constructed to the appropriate standard and be no higher 

than necessary to accommodate their intended functions (e.g., traffic volume and weight of 

vehicles). Excessive grades on roads, road embankments, ditches, and drainages shall be avoided, 

especially in areas with erodible soils. Special construction techniques shall be used, where 

applicable. Abandoned roads and roads that are no longer needed shall be recontoured and 

revegetated. 

2.	 Access roads and on-site roads shall be surfaced with aggregate materials, wherever appropriate. 

3.	 Access roads shall be located to follow natural contours and minimize side hill cuts. 

4.	 Roads shall be located away from drainage bottoms and avoid wetlands, if practicable. 

5.	 Roads shall be designed so that changes to surface water runoff are avoided and erosion is not 

initiated. 

6.	 Access roads shall be located to minimize stream crossings. All structures crossing streams shall 

be located and constructed so that they do not decrease channel stability or increase water 

velocity. Operators shall obtain all applicable federal and state permits. 

7.	 Existing drainage systems shall not be altered, especially in sensitive areas such as erodible soils 

or steep slopes. Potential soil erosion shall be controlled at culvert outlets with appropriate 

structures. Catch basins, roadway ditches, and culverts shall be cleaned and maintained regularly.

commensurate with road types, traffic volumes, vehicle types, and site-specific conditions, to 

ensure safe and efficient traffic flow and to reduce wildlife collisions and disturbance and 

airborne dust. 

2.	 Traffic shall be restricted to the roads developed for the project. Use of other unimproved roads 

shall be restricted to emergency situations. 

3.	 Signs shall be placed along construction roads to identify speed limits, travel restrictions, and 

other standard traffic control information. To minimize impacts on local commuters, 

consideration shall be given to limiting construction vehicles traveling on public roadways during 

the morning and late afternoon commute time. 

Air Emissions 

1.	 Dust abatement techniques shall be used on unpaved, unvegetated surfaces to minimize airborne 

dust. 

2.	 Speed limits (e.g., 25 mph [40 km/h]) shall be posted and enforced to reduce airborne fugitive 

dust. 

3.	 Construction materials and stockpiled soils shall be covered if they are a source of fugitive dust.

throughout the operational phase, as appropriate. These control and mitigation measures shall be 

reviewed and revised, as needed, to address changing conditions or requirements at the site, 

throughout the operational phase. This adaptive management approach would help ensure that 

impacts from operations are kept to a minimum. 

2.	 Inoperative turbines shall be repaired, replaced, or removed in a timely manner. Requirements to 

do so shall be incorporated into the due diligence provisions of the ROW authorization. Operators 

will be required to demonstrate due diligence in the repair, replacement, or removal of turbines; 

failure to do so could result in termination of the ROW authorization. 

Wildlife 

1.	 Employees, contractors, and site visitors shall be instructed to avoid harassment and disturbance 

of wildlife, especially during reproductive (e.g., courtship and nesting) seasons. In addition, any 

pets shall be controlled to avoid harassment and disturbance of wildlife.

Appendix VIII - Hollister Field Office Reasonably Foreseeable 

Development Scenario for Oil and Gas 

I. Summary 

Based on an analysis of past oil and gas related activities within the boundaries of the Hollister Field 

Office (HFO) and the very small amount of federal mineral estate within areas of high development 

potential, we project that oil and gas activities on federal mineral estate within the Hollister Field Office 

area boundary will continue at a relatively minimal level. Overall, within the next 15-20 years, we project 

total surface disturbance due to all oil and gas activities on federal mineral estate to be no more than 74 

acres. This estimate includes geophysical exploration (seismic), 5 exploration wells, 10 development 

wells and associated facilities, roads, and a transmission pipeline that could be linked to existing 

transmission lines within the area. One third of this disturbance, 26 acres, will be temporary, and would 

be mostly to totally reclaimed within a few months to a couple of years. Over the long term, both new 

and existing oil and gas related activities would eventually be abandoned, the lands would be reclaimed, 

and the sites would be restored to as near a natural condition as practical. 

The total surface disturbance for up to 10 development wells would be 10 acres for well pads, 12 acres for 

roads, and 24 acres for a single transmission line 10 miles long. No more than 1 acre would be required 

for the small facility (meter, separator) on each of two parcels, for a total of 2 acres. The total surface 

disturbance caused by seismic operations, exploration drilling, and development would be 74 acres, as 

summarized below.

II. Introduction 

This appendix describes the scenario for the Reasonably Foreseeable Development (RFD) of oil and gas. 

The RFD scenario estimates the level and type of future oil and gas activity in the planning area and 

provides a basis for the analysis of cumulative effects. Based on current regulations and the small amount 

of projected activity on federal mineral estate within the planning area, this RFD is applicable regardless 

of which of the alternatives analyzed in the EIS is chosen as the Preferred Alternative. 

The scenario first describes the steps involved in exploring for and developing deposits of oil and gas. 

Trends and assumptions affecting oil and gas activity are discussed in this appendix, followed by 

estimates for future oil and gas exploration and development.

The scenario for reasonably foreseeable development is based on known or inferred oil and gas potential, 

and applies the conditions and assumptions discussed below. Changes in available geologic data or 

economic conditions may alter this scenario, and some deviation should be expected over time. The lands 

included are limited to those with BLM-administered minerals, including split estate with federal 

minerals. 

It should be noted that not all mineral estate managed by the BLM may have been identified at this time. 

For purposes of this document, we consider that all mineral estate managed by the BLM is covered by 

this RFD, even if we do not currently show the mineral estate on BLM maps. We also consider that 

mineral estate on lands that may be acquired in the future will also be covered by this RFD so long as the 

values and resources that are contained on the newly acquired lands do not differ significantly from those 

on existing known federal mineral estate. 

III. Petroleum Geology of the Hollister Field Office Area 

Refer to Section V, Oil and gas Occurrence and Development Potential. 

IV. Past and Present Oil and Gas Exploration and Development 

Activity 

There are 30 active oil fields and gas fields within the HFO management area, with a total administrative 

area of 188,000 acres. Within those administrative areas, the actual productive areas total about 58,000 

acres. Since 1984, more than 1000 wells have been drilled within the HFO area, 93% of which were 

within field boundaries, with only 7% being classified as wildcats (outside administrative field 

boundaries). Although there are nearly 5400 acres of federal mineral estate within these productive 

boundaries (9% of the total), there was not a single well on federal mineral estate. This trend is not likely 

to change much, because nearly all of the activity in each of the past 10 years occurred in 3 fields where 

the federal share of mineral estate is only 1%. 

Regarding new field discoveries, there have been fewer than 3 fields discovered since 1984, none of 

which contained federal mineral estate. Because of the low amount of activity on federal mineral estate, a 

more detailed description of past and current activities throughout the entire HFO area is unnecessary. 

V. Oil and Gas Occurrence and Development Potential 

The Hollister Field Office has areas of high, moderate, and low to none development potential. The size 

of each category is shown below. 

Category: Total Acres: 

High 1,883,449 

Moderate 2,402,432 

Low to None 2,529,259 

Total 6,815,140 

High Development Potential 

The areas of high oil/gas development potential occur in five areas. The areas, a total of 1,883,000 acres, 

are depicted in pink on Map 10. They will be described from north to south.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

The first area of high oil/gas development potential is in the extreme northern part of the Hollister Field 

Office area in Contra Costa County. This area is dominated by gas fields that produce from Eocene and 

Paleocene sedimentary rocks. 

The second area of high oil/gas development potential is in the Santa Clara Mountains of southeastern 

San Mateo and northwestern Santa Cruz Counties. There are no presently active oil or gas fields in the 

area. However, several drilling programs have identified potential production (“shows”) from Lower 

Tertiary and Upper Cretaceous formations in this area. 

The third area of high oil/gas development potential is in the central part of the Hollister Field Office area 

in northern San Benito County. The Sargent Oil Field produces from the Miocene Monterey Formation 

and Pliocene Purisima Formation of the San Juan Valley sedimentary basin. 

The fourth area of high oil/gas development potential is in southeastern San Benito County and western 

Fresno County. This area is part of the San Joaquin Basin, and has several oil fields that produce from 

Miocene and Pliocene marine sedimentary rocks. 

The fifth area of high oil/gas development potential is in southwestern San Benito County and 

southeastern Monterey County. The most important oil/gas field in this area is the San Ardo field. It, and 

the other oil fields in the area, produce from the Miocene Monterey formation in the Salinas sedimentary 

basin. 

Moderate Potential 

There are several areas of moderate potential within the Hollister Field Office area. These areas, a total of 

2,402,000 acres, are shown in yellow on Map 10. They are described as areas with Upper Cretaceous or 

Lower Tertiary sedimentary rocks containing many wells with oil and gas “shows” or even production, 

although generally not in economic quantities. Although these areas may contain numerous wells that 

either had production at one time, or had “shows”, they are classified as having only moderate potential 

because the rocks in this area are generally more highly fractured, and do not generally have trapping 

styles or cap rocks that permit sustained development from oil/gas accumulations. 

In the southern part of the Hollister Area Office, these rocks are found in three strips along the western 

central and eastern parts of the Area Office. The eastern strip of Moderate oil/gas potential lies west of 

high-potential areas of the Sacramento-San Joaquin Basin. This strip lies east of a mass of crystalline and 

Franciscan metamorphic rocks in the center of the Field Office Area, including the Clear Creek 

Management Area in the Diablo Mountain Range. 

The central strip of moderate oil/gas potential is bounded on the east by a mass of crystalline and 

Franciscan metamorphic rocks of the Diablo Range and a similar set of igneous and metamorphic rocks in 

the Coast Ranges. 

The western strip of moderate oil/gas potential occurs between the coast and the western foothills of the 

Coast Ranges. 

Low to None Development Potential 

There areas of low to none (hereafter “low”) oil/gas development potential is defined as areas that are 

underlain dominantly by crystalline igneous rocks and metamorphic rocks of the Franciscan Formation.

These areas of low oil/gas development potential, a total of 2,529,000 acres, are shown in green on Map 

10. 

There are five low potential zones in the Hollister Field Office. The low potential rocks occur in three 

discontinuous bands that run north-northwest to south-southeast in the eastern, central, and western parts 

of the Area Office. 

The eastern low potential zone is located in the Diablo Mountains and in the Tumey-Panoche Hills. It is 

divided into northern and southern segments by the Vallecitos Trough. 

The central low potential zone is located in the Coast Ranges as the core of a crystalline igneousmetamorphic faulted complex. 

The western low potential zone has two components. The northern component is in the Santa Lucia 

Range, and the southern component in the Santa Lucia Range.

VI. RFD Baseline Scenario Assumptions, Discussion, and Estimated 

Surface Disturbance from Oil and Gas Activity on Federal Mineral 

Estate in the Hollister Field Office Area 

For purposes of this document, we have assumed that all potentially productive areas are open under 

standard lease terms and conditions, except those areas designated as closed to leasing by law, regulation, 

or executive order. 

Future trends and assumptions: Based on the history of minimal activity for oil and gas exploration and 

development on federal lands within the planning area, activity over the next 15 to 20 years is likely to be 

sporadic. Oil and gas activity will probably consist of the issuance of some competitive and over-thecounter leases, a few geophysical surveys, and perhaps the drilling of 3-5 exploratory wells, with no more 

than 10 development wells, and the associated facilities/gas transmission lines. It is very unlikely that 

more than a total of 15 exploratory and development wells will be drilled on new federal oil and gas 

leases. While the large majority or even all of this activity is expected to occur in areas identified in this 

RFD as “High Development Potential,” there is always a possibility that federal minerals in other areas 

may see geophysical exploration, leasing, and even actual exploration and development drilling. It is 

highly unlikely that any wells in such an area would be productive, so any associated surface disturbance 

would likely be short term. 

Geophysical exploration: Geophysical exploration is conducted to determine the subsurface structure of 

an area and the potential for mineral resources. There are three geophysical survey techniques that are 

generally used to define subsurface characteristics through measurements of the gravitational field, 

magnetic field, and seismic reflections. 

Gravity and magnetic field surveys—involve small, portable measuring units that are easily transported 

by light off-highway vehicles, such as 4-wheel drive pickup trucks and jeeps, or aircraft. Both off and onhighway travel may be necessary. Although these two survey methods can take measurements along 

defined lines, it is more common to have a grid of distinct measurement stations. Surface disturbance

resulting from these surveys is negligible, consisting almost exclusively of soil or vegetation compaction 

that persists no more than a few months. 

Seismic reflection surveys—are the most common of the geophysical methods, and they produce the most 

detailed subsurface information. Seismic surveys are conducted by sending shock waves, generated by a 

small explosion or by mechanically beating the ground with a thumping or vibrating platform. 

In the explosive method, small charges are detonated on the surface or in a shallow drill hole. The 

surface charge method uses 1 to 5-pound charges attached to wooden laths 3 to 8 feet above the ground. 

Placing charges lower than 6 feet usually results in destruction of vegetation, whereas placing the charges 

higher, or on the surface of deep snow, results in little visible surface disturbance. In the drill hole 

method, holes for the charges are drilled using truck-mounted or portable air drills. In general, this 

method uses 4 to 12 holes per mile of line, and a 5 to 50-pound explosive charge is placed in each hole, 

covered, and detonated. The shock wave created is recorded by geophones placed in a line on the surface. 

In rugged terrain, a portable drill carried by helicopter can sometimes be used. The vehicles used for a 

drilling program may include heavy truck-mounted drill rigs, track-mounted drill rigs, water trucks, a 

computer recording truck, and a light pickup. 

In the mechanical method, four large trucks are usually used, each equipped with pads about 4-feet 

square. The pads are lowered to the ground, and the vibrations are electronically triggered from the 

recording truck. Once information is recorded, the trucks move forward a short distance and the process is 

repeated. Surface disturbance includes flattening of vegetation and compaction of soils. 

In either type of seismic reflection surveys, existing roads and trails are used where possible. However, 

off-road travel is necessary in some cases. Several trips per day are made along a seismograph line, 

usually resulting in a well defined two-track trail. 

It is expected that no more than three Notices of Intent, involving seismic reflection and gravity/magnetic 

field surveys across federal surface, would be filed under all Alternatives and the Proposed RMP during 

the life of this plan. Although it is unlikely, it is possible that one or two of the parcels with federal 

surface could be involved in a 3-D seismic proposal. If that occurs, the total expected surface disturbance 

could be up to 9 acres, based on up to 25 miles of seismic lines and a two track road with each track being 

18” wide. It is possible that much of the travel could be located on existing roads or other previously 

disturbed lands, and there could be some hand laying of lines, and that would result in less new 

disturbance. 

Drilling phase: After a parcel is leased, there may or may not be any actual disturbance. In fact, 

historically, a large majority of leases are relinquished without ever having any actual surface disturbance. 

In the event that an Application for Permit to Drill (APD) is submitted, a site specific evaluation will be 

made by the BLM to ensure compliance with NEPA requirements. Based on the results of that 

evaluation, additional Conditions of Approval may be added, and the operator may only begin 

construction after complying with lease stipulations and Conditions of Approval of the drilling permit. 

When a site requires construction of an access road, the shortest feasible route is usually selected to 

reduce the haul distance and construction costs. Environmental factors or a landowner’s wishes may 

dictate a longer route in some cases. Drilling in the planning area is expected to be done using existing 

roads and construction of only short (approximately 0.5 mile) roads to access drill site locations. 

Even though there are 30 active oil fields and gas fields that are partly or totally within the Hollister FO 

area, only 9% land within the productive boundaries of those fields contains federal minerals (5400 

federal acres out of a total of more than 58,000 acres). In the past ten years, 1030 wells have been drilled

in the entire FO area, but no wells have been drilled on federal minerals within the entire FO area. 

Consequently, based on the history of oil and gas exploration in the planning area, it is projected that no 

more than three to five exploratory wildcat wells (wells outside of the administrative boundary of existing 

oil and gas fields) would be drilled on BLM-administered land in the planning area during the life of this 

plan. Although the success rate for wildcat wells has improved markedly during the past decade, largely 

due to improved seismic data, it is still unlikely that any new fields would be discovered by drilling on 

federal minerals because there is so little activity in areas with significant amount of federal mineral 

estate. 

Most drilling is expected to occur in areas of land designated as high development potential (shown on 

Map 10). Although there is a low probability that a field will be discovered on federal land during the life 

of this plan, if a field containing federal land were to be discovered in the northern portion of HFO area, it 

is likely that the discovery would be gas because all of the occurrences in that area are gas. Conversely, if 

a field containing federal land were to be discovered in the southern portion of HFO area, it is likely that 

the discovery would be oil because all of the occurrences in that area are oil. 

During the first phase of drilling, the operator would move construction equipment over existing 

maintained roads to the point where the access road begins. Less than 0.5 mile of moderate duty access 

road per well with a gravel surface 20 feet wide is expected for construction. With ditches, cuts, and fill, 

the total width of surface disturbance would average 40 feet. The second part of the drilling phase is the 

construction of a drill pad up to 1 acre in size. The likely duration of well drilling, testing, and 

abandonment is 3 or 4 months per site. The total disturbance for each exploratory well and any new road 

is estimated to be 3.4 acres. The total surface disturbance caused by exploratory drilling of 3-5 wells over 

the life of this plan is expected to be no more than 10-17 acres. 

Field development and production: Exploratory drilling is not expected to lead to the development of a 

producing field in the planning area. Nonetheless, the following scenario describes the operations and 

effects associated with field development. 

The minimum size considered economically feasible would depend mainly on its proximity to existing 

infrastructure. There are many fields within the boundaries of the HFO area, mostly in the extreme 

southern and extreme northern portions of the area, and it is likely that any pipelines from a new field 

would be relatively short. The wells within the actual productive boundaries (smaller than the 

administrative boundaries) of gas fields are spaced on average at 80-160 acres. For oil fields in the HFO 

area, spacing is much closer. In the larger oilfields, usual development spacing is typically at 5-7 acres 

per well. However, spacing can be as close as one well per acre in areas with heavy oil. Although it is 

unlikely that a new field will be discovered on federal minerals, for planning purposes we will assume a 

fairly small to mid size oil field may be discovered somewhere within the planning area. The average 

field size in the FO area is over 1900 acres, but that is significantly skewed by the presence of a few very 

large fields. The bottom 80% of the active fields in the FO area average 650 acres, about one square mile. 

If a single oilfield of that size was discovered, on average it would contain 9.1% federal mineral estate, 

about 60 acres. At 5-7 acres per well, it would take approximately 10 wells to fully develop the parcel. 

Each development well would require an estimated 0.25 mile of road, which would have a surface of 

crushed aggregate or gravel approximately 20 feet wide (total disturbed width of 40 feet). Well pads 

would be no more than 1 acre in size. Oil/gas produced would be carried by pipelines that could be 

linked to existing and proposed transmission lines in the planning area. Average infield pipeline length is 

estimated to be 0.25 mile per well, which could probably be largely contained within the road right of 

way and little new surface disturbance would be required. The total distance from a new field to an 

existing transmission pipeline is likely to be less than 10 miles. The width of the surface disturbance for 

pipelines would average 20 feet.

BLM Hollister Field Office Clear Creek Management Area
 

Record of Decision Resource Management Plan
 

The total surface disturbance for up to 10 development wells would be 10 acres for well pads, 12 acres for 

roads, and 24 acres for a single transmission line 10 miles long. No more than 1 acre would be required 

for the small facility (meter, separator) on each parcel. For planning purposes, we will assume that the 

wells may be on two separate parcels, so there would be a total of 2 acres for facilities. The total surface 

disturbance caused by seismic operations, exploration drilling, and development would be 74 acres. 

Plugging and abandonment: Wells that are drilled and determined to be dry holes are plugged according 

to a plan designed for the condition of each well. Plugging involves placing cement plugs at strategic 

locations in the hole. Drilling mud is used as a spacer between the plugs to prevent communication 

between fluid-bearing zones. The drill casing is cut off at least 5 feet below ground level and capped by 

welding a steel plate on the casing stub. After plugging, all equipment and debris would be removed and 

the site restored as near as reasonably possible to its original condition. It is projected that much of the 

surface disturbance from exploratory activities and all of the seismic activities would be of short duration 

(between a few months and a couple of years). The impacts from the successful development wells 

would last longer, but it would still be reclaimed eventually. 

Military Bases – Fort Hunter Liggett military base is within the planning area. Leasing these lands 

requires consent from the local Base Commander. It has been shown in numerous cases across the 

country and within California that oil and gas exploration and development can often be conducted in a 

manner that is fully compatible with ongoing military operations. It is quite possible that negotiations 

between BLM and military personnel may result in agreement to lease lands within the boundaries of 

bases or other military lands. In the event that happens, appropriate leasing stipulations that would fully 

protect the military’s mission will be added prior to any land being leased.

Summary – CCMA 

5/29/12 

A.	 Areas of Agreement 

1.	 Activity Based Methodology is an effective approach 

2.	 Location under discussion is the area within the ACEC Boundary 

3.	 Staging/Camping No Longer Occur - Agreed it is appropriate to disregard risk factors 

related to staging/camping within the ACEC in future risk calculations 

4.	 Capping does reduce risk, but would still need to be monitored and measured to 

determine exposure as time goes on 

5.	 Key Elements to evaluate risk: Duration, Frequency, and Concentration 

6.	 Lead Rider is exposed to much less risk 

B.	 Areas of Concern 

1.	 Trailing Rider Effect 

- Normal riding styles – are there possibilities to lower risk? 

o Require distance between riders? 

 Is trailing rider effect less pronounced on trails than it is on 

roads? 

 At what distance does trailing rider receive significantly less 

exposure? 

o	 Would using monitors in helmet provide significantly lower exposure 

levels than monitors placed on chest? 

2.	 “Wet Season Riding”

- No consistent rain patterns at CCMA 

- How much rain, and at what frequency, would there need to be to 

significantly reduce risk factors? No solid information in this regard has been 

collected. 

3.	 Clear Creek Road – Road vs. Trail riding 

- Riders avoid dust trail when riding on trails, but encounter higher levels of 

dust when riding on roads. Data in the existing studies does not provide the 

ability to support if riders on trails experience lower levels of exposure or not. 

o Capping road may be a solution 

 Exposure levels after capping would need to be evaluated. 

New risk calculation could possibly be made based on trail 

riding exposure levels and reduced exposure on roads. 

 The relative distances traveled on roads vs. traveled on 

trails and the resulting reduction in risk that might be 

expected from capping the roads needs to be evaluated. 

C.	 Opportunities for additional research 

	 Rider behavior to avoid dust & areas where most dust would be encountered – roads vs trails & 

the efficacy of capping roads. 

 Efficacy of 1-way roads & trails to limit dust. 

 Climate studies of the areas rainfall patterns. Soil studies on moisture content and generation of 

dust. 

 Further research to evaluate risk during moist conditions in the days and weeks following a rain 

event.
