APPENDIX B2 – NOXIOUS WEED MANAGEMENT PLAN

B2.1 Introduction

B2.1.1 Background

Maintaining ecosystem health is a principal objective of land management planning and the expansion of

noxious weeds is a central obstruction to fulfilling this objective. The Plant Protection Act of 2000 (7

United States Code [U.S.C.] 7701 et seq.) defines a noxious weed as “any plant or plant product that can

directly or indirectly injure or cause damage to crops (including nursery stock or plant products),

livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the

United States, the public health, or the environment.” The highly competitive and opportunistic nature of

noxious weeds often prevents native plant species from re-establishing advantageous communities in

disturbed areas. The intent of this Noxious Weed Management Plan is to provide a framework of

principals and procedures to be used to prevent the introduction and spread of noxious weeds associated

with the construction, operation, and maintenance of the Energy Gateway South Transmission Project

(Project).

The format and content of this Noxious Weed Management Plan is based on the principles and procedures

outlined in the Bureau of Land Management (BLM) Integrated Weed Management Manual 9015 and U.S.

Forest Service (USFS) Noxious Weed Management Manual 2080. This plan includes a discussion on (1)

the plan purpose and objectives, (2) the noxious weed inventory to be completed, (3) management

practices, (4) monitoring, and (5) the use of pesticides/herbicides.

B2.1.2 Plan Purpose

The U.S. Department of Agriculture (USDA), Wyoming Department of Agriculture, Colorado

Department of Agriculture, and Utah Department of Agriculture and Food have each identified noxious

weed species that occur in their respective jurisdictions. A number of listed noxious weed species have

the potential to be introduced or spread along the Project right-of-way as a result of actions associated

with the Project. This Noxious Weed Management Plan provides methods to control the potential

establishment and/or spread of noxious weeds during and following construction of the Project. It is the

responsibility of PacifiCorp (Company), and the Construction Contractor(s) working in coordination with

both the Compliance Inspection Contractor (CIC) and the respective federal land-management agencies’

Authorized Officers or their designated representatives to ensure noxious weeds are identified and

controlled during construction, operation, and maintenance of Project facilities and that all federal, state,

county, and other local requirements are satisfied. The control of invasive species (not classified as

noxious weeds) is addressed in Appendix C1 – Reclamation, Revegetation, and Monitoring Plan

Framework.

B2.1.3 Goals and Objectives

The goal of this plan is to implement early detection measures, containment techniques, and control

methods associated with listed noxious weed species during Project construction, operation, and

maintenance. Information assembled by the Company during preconstruction surveys and provided by the

land-management agencies will be used to monitor and control the spread of noxious weeds during the

construction and operation of the Project. The prevention and treatment measures are described in

Section B2.4 – Noxious Weed Management. An evaluation of the effectiveness of the prescribed control

measures described in Section B2.4 also will be implemented during the operational phase of the Project.


B2.2 Regulatory Framework

The following overview provides a brief account of federal legislation, state legislation, and related

regulatory compliance requirements applicable to noxious weed species and approved noxious weed

management techniques as applied to the Project area.

B2.2.1 Plant Protection Act of 2000

The Plant Protection Act of 2000 (7 U.S.C. 7701 et seq.) counteracts importation, exportation, and

proliferation of noxious plant species by merging and modifying previous statutes (the Federal Noxious

Weed Act of 1974, the Plant Quarantine Act, and the Federal Plant Pest Act) associated with plant

protection and quarantine. The act authorizes the Animal and Plant Health Inspection Service (APHIS) to

direct noxious weed matters.

B2.2.2 Federal Environmental Pesticide Control Act

The Federal Environmental Pesticide Control Act (7 U.S.C. 136 et seq.) entirely amends the Federal

Insecticide, Fungicide, and Rodenticide Act. The act bestows federal oversight of pesticide distribution,

transaction, and manipulation to the U.S. Environmental Protection Agency and establishes strict

administrative registration of all pesticides.

B2.2.3 Carlson-Foley Act

The Carlson-Foley Act (43 U.S.C. 1241) directs federal land-management agencies to destroy noxious

weeds growing on land under their jurisdiction and provides a legal framework for reimbursement of

expenses to state or local agencies for weed control on federal land.

B2.2.4 Executive Order 13112

Executive Order 13112 requires federal agencies to prevent the introduction and spread of invasive

species, detect and respond rapidly to control such species, monitor invasive species populations, and

restore native species and habitat conditions in ecosystems that have been invaded. In addition, the order

requires that a federal agency “not authorize, fund, or carry out actions that it believes are likely to cause

or promote the introduction or spread of invasive species.”

B2.2.5 Bureau of Land Management Resource Management Plans and Management Framework Plans

BLM Resource Management Plans (RMP) and Management Framework Plans for Wyoming, including

Rawlins Field Office (2008); for Colorado, including White River (1997, as amended) and Little Snake

Field Offices (2011); for Utah, including Richfield (2008), Fillmore (1987), Price (2008), Vernal (2008),

and Salt Lake District Field Offices (1990), specify regulations and goals for management of BLM-

administered lands and set restrictions to protect fish and wildlife and the habitats on which they depend.

Many of these documents also describe the locations and approximate quantities of known noxious weed

species in the jurisdictional boundaries of the field offices.

B2.2.6 U.S. Forest Service Land and Resource Management Plans

USFS Land and Resource Management Plan for Manti-La Sal (1986, as amended) and Uinta (2003, as

amended) National Forests identify goals for forest health and constraints on resource uses to meet these

goals.


B2.2.7 Bureau of Land Management Manual 9015

Integrated Weed Management Manual 9015 directs the BLM to manage noxious weeds and undesirable

plants on BLM lands by preventing establishment and spread of new infestations, reducing existing

population levels, and managing and controlling existing stands. Required management for ground-

disturbing actions includes determining the risk of spreading noxious weeds associated with the Project

and ensuring contracts contain provisions that hold contractors responsible for the prevention and control

of noxious weeds caused by their operations if the activity is determined to be moderate to high risk.

B2.2.8 Bureau of Land Management Manuals 1740-1 and 1740-2

BLM Manual 1740-1 – Integrated Vegetation Management (2008) and BLM Manual 1740-2 –Renewable

Resource Improvement and Treatment Guidelines and Procedures (1987) outline policies, objectives, and

standards focused primarily on planning, analyzing, constructing, maintaining, replacing, or modifying

renewable resource improvements and treatments, such as for forestry, invasive species, and range

management.

B2.2.9 U.S. Forest Service Manual 2080

U.S. Forest Service Noxious Weed Management Manual 2080 directs each Forest Supervisor to manage

noxious weeds on national forest system lands to achieve goals and objectives identified in forest land and

resource management plans. Per the manual, the USFS will determine the risk of spreading noxious

weeds associated with proposed ground-disturbing activities and must identify and implement control

measures for moderate to high risk activities in the Project decision document. USFS Manual 2080 also

authorizes contract and permit clauses to prevent the introduction or spread of noxious weeds by

contractors or permittees.

B2.2.10 U.S. Forest Service Manual 2900

USFS Manual 2900, Invasive Species Management, sets forth National Forest System policy,

responsibilities, and direction for the prevention, detection, control, and restoration of effects from aquatic

and terrestrial invasive species (including vertebrates, invertebrates, plants, and pathogens).

B2.2.11 Wyoming Weed and Pest Control Act

Wyoming Weed and Pest Control Act (Title 11, Chapter 5, Article 1) officially designates the authority of

the State of Wyoming to require the control of designated pests and weeds.

B2.2.12 Wyoming Environmental Pesticide Control Act

Wyoming Environmental Pesticide Control Act (Title 35, Chapter 7, Section 35-7-350 to 35-7-376)

regulates the labeling, distribution, storage, transportation, disposal, use, and application of pesticides

used to control pests and weeds.

B2.2.13 Colorado Noxious Weed Act

Colorado Noxious Weed Act (Title 35, Article 5.5) officially designates the authority of the State of

Colorado to require the control of designated pests and weeds.


B2.2.14 Colorado Pesticide Act

Colorado Pesticide Act (Title 35, Article 9) regulates the labeling, distribution, storage, transportation,

disposal, use, and application of pesticides used to control pests and weeds.

B2.2.15 Utah Noxious Weed Act

Utah Noxious Weed Act (Rule R68-9) officially designates the list of weeds as noxious for the State of

Utah, equipment capable of disseminating those weeds, and treatments considered to prevent

dissemination of weed seeds or parts of noxious weed plants that could cause new growth by

contaminated equipment, as per the authority vested in the Commissioner of Agriculture and Food under

Section 4-17-3.

B2.2.16 Utah Pesticide Control Act

Utah Pesticide Control Act (Rule R68-7) regulates the labeling, distribution, storage, transportation,

disposal, use, and application of pesticides used to control pests and weeds.

B2.3 Noxious Weed Inventory

Information regarding the presence and distribution of noxious weeds was collected incidental to

biological resource surveys. Target species during this inventory included weed species designated

noxious by the USDA as well as the states of Wyoming, Colorado, and Utah, as well as county weed

management agencies in counties crossed by the Project. In addition, information regarding known

noxious weed occurrences in the Project area has been provided to the extent of available records. The

noxious weed information contained in the plan should not be considered to be comprehensive and

additional monitoring and inventories will be required during construction to comply with the goals and

objectives in this Plan. Further information regarding survey, coordination, and reporting requirements

regarding noxious weeds are located in Section B2.4.1 – Identification of Problem Areas and Education

and Section B2.5.2 – Ongoing Monitoring and Control.

B2.3.1 Federally Listed Noxious Weeds

The Plant Protection Act of 2000 authorizes APHIS to designate national-priority noxious weed species

through compilation of a federal noxious weed list. The act also requires that federal land-management

agencies control designated federal noxious weeds in addition to developing and implementing

cooperative noxious weed control agreements with state agencies. Four federally designated noxious

weed species are reported to occur in states crossed by the Project (Table B2-1 – Federally Listed

Noxious Weed Species of Potential Concern - State Occurrence) (USDA 2014).

B2.3.2 State-listed Listed Noxious Weeds

The states of Wyoming, Colorado, and Utah each maintain official lists of plant species designated as

noxious weeds. While state management priorities are outlined below, all noxious weeds in the Project

area will be treated as outlined in this plan.

B2.3.3 Wyoming State-listed Listed Noxious Weeds

The State of Wyoming has officially designated 25 weed species as noxious (Table B2-2 – Wyoming

State-listed Noxious Weed Species of Potential Concern). Collectively, Wyoming counties crossed by the

Project have 11 additional county declared noxious weeds.

NOTE: 1Bureau of Land Management Rawlins Field Office does not require control of county declared species, as many are

native species.

B2.3.4 Colorado State Listed Noxious Weeds

The State of Colorado has categorically designated 75 weed species as noxious (Table B2-3 – Colorado

State-listed Noxious Weed Species of Potential Concern). In addition, Colorado also maintains a series of

26 Watch List species that have been identified to present a potential risk to agricultural and

environmental resources. The Watch List is intended to operate solely as an informative and consultative

instrument to facilitate the collection of data used in determining future noxious weed designations.

Watch List species are not considered in this noxious weed management plan because the species do not

hold official designation as noxious weeds. Watch List species may be considered invasive species and

control measures regarding invasive species (not classified as noxious weeds) are addressed in Appendix

C1 – Reclamation, Revegetation, and Monitoring Plan Framework. Categorical designations of noxious

weed species list groups of species in order of prioritization as follows:

List A

Eradication

Declared noxious weeds that pose a serious threat to the state and are identified as highest priority

for eradication

List B

Containment and Control

Declared noxious weeds that pose a threat to the state. Actions are designed to stop the continued

spread of listed species.

List C

Local Planning and Support

Develop and implement state noxious weed management plans to support locally integrated weed

management actions on both public and private jurisdictions. The objective of local planning will

not be focused on discontinuing the spread of List C species but is intended to afford educational,

research, and biological control assets to jurisdictions that may require management of List C

species.

B2.3.5 Utah State Listed Noxious Weeds

The State of Utah has categorically designated 29 weed species as noxious (Table B2-4 – Utah State

Listed Noxious Weed Species of Potential Concern). Collectively, Utah counties crossed by the Project

have designated 6 additional county declared noxious weeds. The State of Utah categorical designation of

noxious weed species lists groups of species in order of prioritization as follows:

Class A

Early Detection Rapid Response – Highest Priority

Declared noxious weeds with relatively small populations that pose a serious threat to the state

and are identified as highest priority for eradication.

Class B

Control – High Priority

Declared noxious weeds with moderate-sized populations that pose a threat to the state and are

believed to be controllable in most areas.

Class C

Containment – Secondary Priority

Declared noxious weeds that pose a threat and are located extensively across the state. Efforts

focus on containment of populations.

B2.3.6 Bureau of Land Management Noxious Weed Occurrences

Distribution information available from BLM field office management documents, where available, was

used to determine the presence of noxious weeds in the Project area. Noxious weed information regarding

BLM-administered lands for each state is summarized in the following subsections.

Wyoming

BLM Rawlins Field Office. The BLM Rawlins Field Office RMP EIS confirms the presence of

18 of the 25 Wyoming state-listed noxious weeds in the field office (BLM 2008a) (Table 1 –


State- and County-listed Noxious Weeds in Wyoming for Lands in the Project Area of

Attachment A – Noxious Weed Occurrences). These species on public lands in Wyoming are

managed under the Rawlins Field Office Noxious Weed Prevention Plan (BLM 2008a). The

current, untreated, weed-infested area is estimated at 20,000 acres, but most of the Rawlins Field

Office has not been inventoried for noxious and invasive species (BLM 2008a).

Colorado

BLM Little Snake Field Office. In the field office area, especially in the last 10 years, there has

been an increase in noxious and invasive weeds, including salt cedar, halogeton, Canada thistle,

and cheatgrass. These problems are most evident in the oil and gas production fields and other

locations where native vegetation has been disturbed (BLM 2011). Specific information about the

presence of noxious weed species in this field office is not currently available. The State of

Colorado has categorically designated 75 noxious weed species (Table B2-3 – Colorado State-

listed Noxious Weed Species of Potential Concern) that may be present in the Project area.

BLM White River Field Office. A key element of management on the White River Field Office

is the preventive measure of designating weed-free zones where few or no noxious weeds

presently occur. The weed-free zones are estimated to comprise approximately 19 percent of the

White River Field Office and are located in the north-central and northeast portions of the White

River Field Office (BLM 1997). Specific information about the presence of noxious weed species

in this field office is not currently available. The State of Colorado has categorically designated

75 noxious weed species (Table B2-3 – Colorado State-listed Noxious Weed Species of Potential

Concern) that may be present in the Project area.

Utah

BLM Vernal Field Office. There are more than 23,000 acres of noxious and undesirable weeds

in the Vernal Field Office (BLM 2008d). The Vernal Field Office ROD and Approved RMP

confirms the presence of 17 of the 29 state-listed noxious weed species and 1 county-listed

species (BLM 2008d) (Table 2 – State- and County-listed Noxious Weeds in Utah for Bureau of

Land Management Lands in the Project Area of Attachment A – Noxious Weed Occurrences).

Cheatgrass, though not a state-listed noxious weed, is a major concern in the field office;

approximately 55,700 acres of land in the field office have more than 60 percent cheatgrass cover

(BLM 2008d).

BLM Richfield Field Office. Eleven species from the state list are present in the Richfield Field

Office (BLM 2008b) (Table 2 – State- and County-listed Noxious Weeds in Utah for Bureau of

Land Management Lands in the Project Area of Attachment A – Noxious Weed Occurrences).

This field office also monitors for county-listed noxious weeds and BLM-designated “new and

invading weeds” and other species deemed to have the potential to invade field office ecosystems.

Other nonlisted species, such as cheatgrass, are likewise given consideration when making

management decisions.

BLM Price Field Office. The Price ROD and Approved RMP (BLM 2008c) includes

management prescriptions for 14 noxious weeds identified as occurring in the field office during

the planning process. Twelve of these species are Utah state-listed noxious weeds, one is a

county-listed noxious weed for counties in the Project area, and one is a county-listed noxious

weed for counties outside the Project area (Table 2 – State- and County-listed Noxious Weeds in

Utah for Bureau of Land Management Lands in the Project Area of Attachment A – Noxious

Weed Occurrences).

BLM Fillmore Field Office. The Fillmore Field Office has documented the presence of 10

weeds on the Utah state noxious weed list (Table 2 – State- and County-listed Noxious Weeds in


Utah for Bureau of Land Management Lands in the Project Area of Attachment A – Noxious

Weed Occurrences). Noxious weed inventories have been completed in both Millard and Juab

counties; however, no inventories of noxious weeds have occurred in the particular BLM

Fillmore Field Office lands crossed by the Project. There are approximately 2,000 acres treated

for noxious and invasive weeds in the Fillmore Field Office annually. During 1996 and 1997,

Squarrose knapweed was estimated to be present on 200,000 acres in Juab, Utah, and Tooele

counties (Probert 2013).

BLM Salt Lake Field Office. The Project crosses only very small areas of public land in the

extreme southeast corner of the Salt Lake Field Office. No specific information on noxious weed

occurrence in this area is currently available, as no inventories of noxious weeds have occurred in

the particular BLM lands crossed by the Project in this field office. However, 17 state-listed

noxious weed species are known to occur in the Salt Lake Field Office jurisdiction (Table 2 –

State- and County-listed Noxious Weeds in Utah for Bureau of Land Management Lands in the

Project Area of Attachment A – Noxious Weed Occurrences).

B2.3.7 U.S. Forest Service Noxious Weed Occurrences

Distribution information available from USFS management documents, where available, was used to

determine the presence of noxious weeds in the Project area. Several Utah state-listed noxious weeds are

known to occur within USFS boundaries in the Project area. Noxious weed information regarding the

Manti-La Sal and Uinta National Forests, both located in Utah, is summarized in the following

subsections:

Manti-La Sal National Forest. The Project crosses only very small areas of public land in the

extreme north end of the forest. Several noxious weed species are known to occur across all

elevations of Manti-La Sal National Forest-administered lands (Table 3 – State- and County-

listed Noxious Weeds in Utah for U.S. Forest Service Lands in the Project Area of Attachment A

– Noxious Weed Occurrences). Musk thistle, Whitetop, and Canada thistle are state-listed

noxious weed species prioritized for control efforts (USFS 1986)

Uinta National Forest. The Project crosses portions of the Nephi, Thistle, and Upper Spanish

Fork management areas. The Nephi and Thistle management areas both contain documented

infestations of tamarisk. The Upper Spanish Fork Management Area contains documented

infestations of tamarisk, whitetop, musk thistle and Canada thistle (USFS 2003). Several noxious

weed species are known to occur across all elevations of Uinta National Forest-administered

lands (Table 3 – State- and County-listed Noxious Weeds in Utah for U.S. Forest Service Lands

in the Project Area of Attachment A – Noxious Weed Occurrences).

B2.4 Noxious Weed Management

Regulatory agencies managing lands along the Project alignment have varying requirements for weed

management. A preconstruction survey for noxious weeds using the protocol established by the BLM

Integrated Weed Management Manual 9015 will be conducted by qualified personnel retained by the

Company/Construction Contractor(s) and in consultation with the Project CIC before Project operations

begin.

The management of noxious weeds will be considered throughout all stages of the Project, including:

Educating all construction personnel regarding identified problem areas, the importance of

preventive measures, and treatment methods.


Specific preventive measures to counteract the spread of noxious weeds during construction,

operation, and maintenance activities.

Preconstruction and postconstruction treatment methods to be applied to areas where noxious

weeds are present.

The following is a description of the measures that may be required for noxious weed management as

directed by the BLM, USFS, or State Quarantine Officer. Applicable measures will be agreed upon prior

to the onset of any ground-disturbing activities and this Noxious Weed Management Plan will be

modified accordingly.

B2.4.1 Identification of Problem Areas and Education

Prior to the initiation of construction activities, the Company/Construction Contractor(s) will provide

construction personnel with training and information on the importance of controlling/managing noxious

weeds (refer to Appendix A4 – Environmental and Safety Training Plan). The importance of preventing

the spread of noxious weeds in areas not infested and controlling the proliferation of weeds already

present will be emphasized. Prior to construction, areas of concern previously identified during the weed

survey will be flagged by the Construction Contractor(s) and reviewed by the CIC. This flagging will

alert construction personnel to the presence of noxious weeds and prevent area access until noxious weed

management control measures, as described below, have been implemented. Attachment A – Noxious

Weed Occurrences identifies general portions of the greater Project area where weed infestations have

been recorded. Noxious weed surveys conducted prior to initiation of ground-disturbing activities will

supplement the information contained in this attachment.

B2.4.1.1 Weed Management Personnel Requirements

Weed management actions shall be carried out by a weed-management specialist with the following

qualifications:

Training and experience in native plant taxonomy/identification

Training and experience in field ecology and plant community mapping

Possession of a Commercial Applicator’s License for pesticides from the appropriate State

Department(s) of Agriculture (if chemical control is used)

Training in weed management or integrated pest management with an emphasis in weeds

Experience in coordination with agency and private landowners

Attendance at an agency-approved noxious weed training course

B2.4.2 Mitigation Measures

The mitigation measures described in this section are applicable to Project construction, reclamation,

operation, and maintenance. Several measures may be required to mitigate both particular impacts and/or

potential impacts associated with construction activities. The following noxious weed mitigation

measures include design features of the Project for environmental protection and selective mitigation

measures derived from the EIS and other specific stipulations and methods.

B2.4.2.1 Design Features of the Project for Environmental Protection

Applied Project-wide, Project design features for environmental protection have been developed in

accordance with BLM and USFS standards and will address many of the concerns associated with

noxious weed management. Following is a description of design features that addresses construction and

operation of Project facilities regarding noxious weed management.


Design Feature 1. In construction areas where recontouring is not required, vegetation will be

left in place wherever possible, and original contour will be maintained to avoid excessive root

damage and allow for resprouting in accordance with the reclamation plan. Vegetation not

consistent with minimum clearance distances between trees and transmission lines must be

removed to ensure line safety and reliability (required by North American Electric Reliability

Council Transmission Vegetation Management Program [2006, 2008, 2009]).

Design Feature 2. In construction areas where there is ground disturbance or where recontouring

is required, surface reclamation will occur as required by the landowner or land-management

agency. The method of reclamation normally will consist of, but will not be limited to, returning

disturbed areas to their natural contour, reseeding, installing cross drains for erosion control,

placing water bars in the road, and filling ditches.

All areas on lands administered by federal agencies disturbed as a part of the construction and/or

maintenance of the Project will be seeded with a seed mixture appropriate for those areas. The

federal land-management agency will approve a seed mixture that fits each range type. Seeding

methods typically will include drill seeding, where practicable; however, the federal land-

management agency may recommend broadcast seeding as an alternative method in some cases.

A Reclamation, Revegetation, and Monitoring Plan Framework identifying reclamation

stipulations will be developed and incorporated into the Plan of Development (POD), which will

be approved by the affected federal land-management agency prior to the issuance of a right-of-

way grant (BLM), special-use authorization (USFS), encroachment permit and grant of easement

(Bureau of Indian Affairs), etc.

Design Feature 5. To prevent the spread of noxious weeds, a Noxious Weed Management Plan

will be developed and incorporated into the POD, which will be approved by the affected federal

land-management agencies prior to the issuance of the BLM and USFS Records of Decision;

BLM right-of-way grant, USFS special-use authorization, BIA encroachment permit and grant of

easement, etc. This plan will be based on the principles and procedures outlined in the BLM

Integrated Weed Management Manual 9015 and Forest Service Noxious Weed Management

Manual 2080. On private land, the Plan will be approved by a county weed-management officer.

Design Feature 9. Based on preconstruction surveys and results of Section 7 consultation, state

and federally designated sensitive plants, habitat, wetlands, riparian areas, springs, wells, water

courses, or rare/slow regenerating vegetation communities will be flagged and structures will be

placed to allow spanning of these features, where feasible, within the limits of standard structure

design.

Design Feature 17. In disturbed temporary work areas, the topsoil will be salvaged/segregated

and distributed and contoured evenly over the surface of the disturbed area after construction

completion. The soil surface will be seeded with an agency-recommended seed mix and left

rough to help reduce the potential for weeds and erosion.

Design Feature 18. Grading will be minimized by driving overland in areas approved in advance

by the land-management agency in predesignated work areas whenever possible.

Design Feature 26. All vehicle movement outside the right-of-way will be restricted to

predesignated access, contractor-acquired access, public roads, or overland travel approved in

advance by the applicable land-management agency, unless authorized by the CIC (during

construction).

Design Feature 27. The spatial limits of construction activities, including vehicle movement, will

be predetermined with activity restricted to and confined within those limits. No paint or

permanent discoloring agents indicating survey or construction limits will be applied to rocks,

vegetation, structures, fences, etc.


Design Feature 33. Consistent with BLM Riparian Management Policy, surface-disturbing

activities within 328 feet (100 meters) of riparian areas (defined as areas of land directly

influenced by permanent surface or subsurface water having visible vegetation or physical

characteristics reflective of permanent water influence, including wetlands, stream banks, and

shores of ponds or lakes) in Utah and Colorado will be required to meet exception criteria defined

by the BLM, such as acceptable measures to protect riparian resources and habitats by avoiding

or minimizing stormwater runoff, sedimentation, and disturbance of riparian vegetation, habitats,

and wildlife species. In Wyoming, surface-disturbing activities within 500 feet (153 meters) of all

perennial waters and/or wetland and riparian areas and 100 feet (30 meters) of all ephemeral

channels also will be required to meet exception criteria in association with the BLM Rawlins

Field Office RMP (BLM 2008a). Mitigation measures will be developed on a site-specific basis,

in consultation with the affected federal land-management agency, and incorporated into the final

POD.

If any disturbance is anticipated within 20 feet of the edge of a riparian area or other wetland

habitat, a silt fence or certified weed-free wattle will be installed along the travel route on the

wetland side unless the wetland is up-gradient.

B2.4.3 Selective Mitigation Measures

The selective mitigation measures to be applied on a site-specific basis to minimize potential adverse

effects related to noxious weeds during construction, operation, and maintenance of the Project are

included below. In selective areas, and on a case-by-case basis, the selective mitigations measures will be

implemented by the Company/Construction Contractor(s) (refer to Volume II – Map Sets of the POD):

Selective Mitigation Measure 1 (Minimize/Avoid Disturbance to Sensitive Soils and

Vegetation). In areas where soils and vegetation are particularly sensitive to disturbance, existing

roads/two-tracks to be used for construction and maintenance will not be widened or otherwise

upgraded; to the extent practicable. To allow construction equipment access to work areas where

the equipment will extend beyond the width of the existing roads, the construction equipment will

straddle the road traveling on the road’s shoulder only where terrain and soil conditions will

allow for safe operation/transport of the equipment (cranes, cement trucks, etc.). Land-

management agencies will work with the Company to determine the extent these existing roads

can be modified versus fully upgraded to ensure the roads/two-tracks are passable and safe for the

equipment and construction and maintenance personnel.

Avoiding unnecessary access road upgrades will limit the amount of habitat disturbed or

removed. Visual contrast introduced through the widening of roads will increase the visibility of

landscape modifications. Avoiding road upgrades will not increase vehicular traffic significantly;

reducing the potential for indirect effects, such as damage or loss of vegetation, spread of noxious

weeds, harassment of wildlife, vandalism of cultural resources, and disturbance to sensitive land

uses. Limiting ground disturbance will reduce exposure of soils highly or moderately susceptible

to wind or water erosion and in proximity to specially designated waters. The potential for

increased erosion and sedimentation as a result of soil compaction/ decompaction will be reduced

as well as the loss of soil-stabilizing vegetation.

Selective Mitigation Measure 2 (Environmental Resources Avoidance). No blading of new

access roads will occur in proximity to certain environmental resources during Project

construction or maintenance. Existing crossings and/or overland access routes will be used for

construction and maintenance in these areas. Methods such as “matting” can be used to stabilize

access to work areas in these sensitive areas. To minimize ground disturbance, overland routes

must be flagged with easily seen markers, and the route must be approved in advance.


Selective Mitigation Measure 2 is effective for the same reasons as Selective Mitigation

Measure 1. Minimizing ground-disturbing construction and clearing activities in areas of

environmental resources will limit the amount of habitat disturbed, removed, or fragmented. This

will reduce the risk of isolation affecting the viability of special status wildlife subpopulations in

these habitat areas. Visual contrast will be reduced by locating and constructing access routes,

including associated vegetation clearing in riparian vegetation communities, where they will be

less visible from viewing locations. Minimizing ground-disturbing construction activities in the

vicinity of specially designated waters will limit soil disturbance, thereby minimizing the

potential for increased erosion and sedimentation. In addition, limiting crossing of trails and other

linear land uses will decrease direct conflicts with their use and function.

Selective Mitigation Measure 3 (Minimize Slope Cut and Fill). The alignment of any new

access roads or cross-country routes in designated areas will follow the landform contours where

practicable to minimize ground disturbance and/or reduce scarring (visual contrast) of the

landscape, providing that such alignment does not impact other resource values. In addition to

reducing ground disturbance associated with the construction of new access roads, modification

to the size and/or configuration of the structure work areas facilitated by minor structure design

adjustments will allow cut and fill slopes to be minimized and contoured to blend with existing

topography to the extent practicable.

Following the existing land contours and terrain minimizes the cutting and filling of slopes and

ensures the form and line of the landscape is not visually interrupted. This results in reducing

visual contrast between the exposed ground of the road or structure work areas and the

surrounding environment. Minimizing slope cut and fill also reduces ground disturbance and

potential habitat fragmentation. Water runoff is less likely to accelerate soil erosion, thus

minimizing potential damage from rutting and drilling, which in turn protects adjacent vegetation.

Selective Mitigation Measure 5 (Minimize New or Improved Accessibility). To limit new or

improved access into the Project area, as well as earthwork associated with the construction of

tower pads in extremely steep terrain, all new or improved access and structure work areas not

required for maintenance will be closed or rehabilitated using the most effective and least

environmentally damaging methods appropriate to that area and developed through consultation

with the landowner or land-management agency. Methods for road closure or management

include installing and locking gates, obstructing the path, revegetating and mulching the surface

of the roadbed to make it less apparent, restoring the road to its natural contour and vegetation, or

constructing waterbars to ensure proper drainage. Tower pads will be contoured to blend with

existing grade and revegetated to the extent practicable to reduce their visual dominance in steep

terrain.

Closing access roads where they are not needed after construction protects the area resources

from further disturbance for the reasons described in Selective Mitigation Measure 1. The closing

of these access roads will restore existing natural features as well as limit public access to wildlife

populations, anthropogenic disturbance, and traffic; consequently reducing erosive attributes.

Additionally, visual contrast will be reduced through restoring existing features in naturally intact

and highly visible areas.

Selective Mitigation Measure 7 (Span and/or Avoid Sensitive Features). Within the limits of

standard tower design and in conformance with engineering and the Company’s requirements,

structures will be located to allow conductors to clearly span identified sensitive features.

Structures will be placed so as to avoid sensitive features, including wetlands, riparian areas,

water courses, hazardous substance remediation, and cultural sites, to the extent possible.

Avoidance measures may include selective tower placement, spanning sensitive features, or

realigning access routes.


Flexibility in the placement of towers allows sensitive features to be avoided. Realigning the

towers along the route or realigning the route, to the extent practicable, itself can result in

avoiding or minimizing direct and indirect impacts on resources, as well as land uses. This

mitigation measure will reduce potential loss, degradation, and fragmentation of wildlife habitat

(including riparian areas); decreasing the risk of isolation between habitat areas and

subpopulations. Additionally, the Project could be realigned, to the extent practicable, in areas

with high concern viewsheds to locate structures for reduced visual contrast and visibility.

Selective Mitigation Measure 11 (Minimize Right-of-way Clearing). Clearing of the right-of-

way will be minimized to avoid environmental resources and reduce visual contrast. In select

areas, the width of vegetation clearing in the right-of-way may be modified (within the limits of

Appendix B4 –Vegetation Management Plan and standard tower design), and/or current land uses

will be allowed to continue unabated, provided the use meets applicable standards.

Limiting the width of the area cleared in the right-of-way reduces the amount of vegetation

removed at the edges of and in the right-of-way. This minimizes habitat loss and reduces visual

contrast between the cleared areas and the surrounding environment. It also allows compatible

land uses to continue.

Selective Mitigation Measure 13 (Overland Access). The Construction Contractor will use

overland access to the greatest extent possible in areas where no grading will be needed to access

work areas. Overland access will consist of drive-and-crush and/or clear-and-cut travel (removal

of all vegetation while leaving the root crown intact to improve or provide suitable access for

equipment). Prior to commencement of work activities, overland access routes will be staked to a

minimum width of 14 feet. Routes will be specified for construction. Use of overland access

routes will be restricted based on dry or frozen soil conditions, seasonal weather conditions, and

relatively flat terrain.

Overland access will avoid or minimize the removal of surface soil and vegetation where soils are

susceptible to wind and water erosion, reducing the potential for erosion and loss of habitat.

Avoiding constructing a new road will reduce the potential for increased traffic and the associated

indirect effects, including the introduction of invasive weeds and special status wildlife habitat

fragmentation.

Selective Mitigation 15 (Limit Accessibility in Sensitive Habitats). Where feasible, access

roads that traverse sensitive habitats will be gated or otherwise blocked in cooperation with the

appropriate land-management agencies to limit public access.

Selective Mitigation 16 (Blend Road Cuts or Grading). Soil amendments, mineral emulsions,

or asphalt emulsions will be applied, or grading techniques, such as slope rounding and slope

scarification, will be used to blend road and structure work area cuts into the landscape in areas of

steep terrain where grading is necessary, in rocky areas, or where soil color will create strong

landscape contrasts.

This mitigation measure will limit public access, reducing stress and disturbance to wildlife and

special status wildlife and their habitats during critical lifecycle periods.

B2.4.3.1 Other Specific Stipulations and Methods

Preventive Measures

The following noxious weed (NW) preventive measures will be implemented to prevent the spread of

noxious weeds during construction activities, reclamation and rehabilitation efforts, and maintenance

operations associated with the Project. Detailed information regarding reclamation, along with the control

of invasive plant species, is provided in Appendix C1 – Reclamation, Revegetation, and Monitoring Plan

Framework.


These preventive measures are to be applied on a case-by-case basis, where applicable and necessary, at

the discretion of the BLM, USFS, CIC, and Construction Contractor’s environmental monitors (weed

specialists).

Attachment A – Noxious Weed Occurrences identifies jurisdictions in the greater Project area where

weed infestations have been recorded. Prior to all ground-disturbing activities, a qualified weed specialist

will survey the right-of-way and all other access roads, work areas, or other proposed disturbance areas.

The weed specialist working in conjunction with the BLM, USFS, and CIC will identify areas where the

following noxious weed measures will be implemented.

NW-1 Where feasible, construction will begin in weed-free areas before operating in weed-

infested areas. The feasibility of this measure will be determined after survey data is

compiled to identify weed-free and weed-infested areas.

NW-2 All construction sites and access roads, including overland access routes, will be clearly

marked or flagged at the outer limits prior to the onset of any surface-disturbing activity.

All personnel shall be informed their activities must be confined within the marked or

flagged areas.

NW-3 Prior to arrival at the work site, all Construction Contractor(s) vehicles and equipment will

be cleaned using high-pressure equipment. Only high-pressure water will be used at wash

stations. The use of compressed air will not be permitted. The cleaning activities will

concentrate on tracks, feet, or tires and the undercarriage with special emphasis on axles,

frame, cross members, motor mounts, underneath steps, running boards, and front

bumper/brush guard assemblies. Vehicle cabs will be swept out. The location of vehicle

cleaning stations will be identified by the Construction Contractor(s), reviewed by the CIC,

and approved by the respective federal land-management agencies’ Authorized Officers or

their designated representatives. Wash stations shall be no more than 1 acre in size and

preferably located in areas that have previously been disturbed. The Construction

Contractor(s) shall provide a detailed design identifying all of the components of the wash

stations, including rock surface and geomembrane layer to provide a barrier between

noxious weeds and seeds and the soil, for approval by the respective federal land-

management agencies’ Authorized Officers or their designated representatives. The

Construction Contractor(s) shall also provide a description of how residue from the wash

station will be disposed of for approval by the respective federal land-management

agencies’ Authorized Officers or their designated representatives. If two or more

noncompliance incidents occur, the agencies will require the wash stations to be manned by

the Construction Contractor(s) at their expense during construction, operation, and

maintenance activities.

NW-4 When moving from weed contaminated areas to other areas along the Project right-of-way,

all construction vehicles and equipment will be cleaned using pressurized water in

designated wash stations before proceeding to new locations. The use of compressed air to

clean equipment will not be permitted. All washing of construction vehicles and equipment

must be performed in approved wash stations.

NW-5 Construction personnel will inspect, remove, and appropriately dispose of weed seed and

plant parts found on their clothing and equipment.

NW-6 The Construction Contractor(s) will ensure vehicles and equipment are free of soil and

debris capable of transporting noxious weed seeds, roots, or rhizomes before the vehicles

and equipment access the Project. The CIC will inspect vehicles to ensure compliance.


NW-7 Whenever possible, temporary disturbance should be avoided in areas with known noxious

weed populations to reduce the risk of spread.

NW-8 In areas where temporary disturbance is necessary and where noxious weeds are identified,

predisturbance treatment of noxious weeds will be implemented. Movement of stockpiled

vegetation and salvaged topsoil will be limited to eliminate the transport of soil-borne

noxious weed seeds, roots, or rhizomes and marked as containing noxious seed materials to

avoid mixing with weed-free soil.

NW-9 During reclamation, the Construction Contractor(s) will return topsoil and vegetative

material containing noxious weeds to their original locations. As directed by the BLM or

USFS, the Construction Contractor(s) may be required to provide additional treatments to

prevent the return of noxious weeds. The Construction Contractor(s) will remove seeds,

roots, and rhizomes from the equipment with pressurized water at approved weed wash

stations before transport offsite.

NW-10 The Construction Contractor(s) will ensure straw or hay bales used for sediment barrier

installations or mulch distribution are obtained from state-cleared sources that are certified

free of primary noxious weeds.

NW-11 Immediately following construction, the Construction Contractor(s) will implement the

reclamation of disturbed land as outlined in Appendix C1 – Reclamation, Revegetation, and

Monitoring Plan Framework as required. Continuing revegetation efforts will ensure

adequate vegetative cover, reducing the potential for the invasion of noxious weeds.

Control Measures

The Company/Construction Contractor(s) will implement noxious weed control measures in accordance

with existing regulations, including BLM and USFS requirements. Control measures will be based on

species specific and site-specific conditions, such as the proximity to water or riparian areas, agricultural

areas, and seasonality, and will be coordinated with the respective federal land-management agencies’

Authorized Officers or their designated representatives, the CIC, and the Company/Construction

Contractor’s weed-management specialist. If existing populations are currently under treatment by the

BLM and USFS or other individuals, the Company/Construction Contractor is encouraged to engage in

cooperative management efforts to treat the noxious weeds associated with the Project area. In the event

new noxious weed populations are identified on the Project in the future, the protocols and methods

outlined in this Plan will be followed. The weed management specialist contracted by the

Company/Construction Contractor(s) shall provide a detailed control methodology for each noxious weed

species documented. The BLM and USFS noxious weed coordinator will review and approve this

Noxious Weed Management Plan prior to implementation. Control measures may include one or more of

the following methods prior to implementation of reclamation actions.

Mechanical

Mechanical methods rely on cutting roots with a shovel or other hand tools or employing equipment that

can be used to mow or disc weed populations. This type of methodology is useful for smaller, isolated

populations in areas of sensitive habitats or if larger populations occur in agricultural lands where tillage

can be implemented. Some rhizomatous weeds can spread by discing or tillage; therefore implementation

will be species specific. If such a method is used in areas to be reclaimed, subsequent seeding will be

conducted to re-establish a desirable vegetative cover that will stabilize the soils and slow the potential re-

invasion of noxious weeds.

NW-12 Discing or other mechanical treatments that will disturb the soil surface in native habitats

will be avoided in favor of pesticide application, which is an effective means of reducing


the size of noxious weed populations, as well as preventing the establishment of new

colonies.

Cultural

Cultural control methods rely on prevention education of the public as well as construction, operation,

and maintenance personnel. Cultural control of noxious weeds also can include the minimization of

vehicular travel through areas of known populations. Noxious weed populations identified during surveys

or by federal land-management agencies/county weed control officials will be cordoned off to avoid

spreading seed or plant materials.

NW-13 Implement preventive measures, such as quarantine and closure, to reduce and contain

existing populations. Flagging will alert personnel and prevent access into areas where

noxious weeds occur. Construction disturbance will be minimized in these areas until

control measures have been implemented (with the exception of reclamation treatments, as

applicable).

NW-14 Reclamation treatments, such as seeding, will be based on site-specific conditions and the

appropriate seed mix approved for those conditions. Seeding will help reduce the spread of

noxious weeds by revegetating exposed soils. If areas are not seeded until the following

spring, because of weather or scheduling constraints, all undesirable vegetation will be

treated before seeding.

Biological

Biological control involves using living organisms (insects, diseases, livestock) to control noxious weeds

to achieve management objectives. Many noxious weed species have been introduced recently into North

America and have few natural enemies to control their population. The biological control agent is

typically adapted to a specific species and selected for their ability to attack critical areas of the plant that

contribute to its persistence. The use of biological control methods is not expected for this Project.

Chemical

Chemical control can effectively remove noxious weeds through the proper use of selective pesticides

(herbicides). Pesticide treatment can be temporarily effective for large populations of noxious weeds

where other means of control may not be feasible. Before construction, only pesticides approved by the

BLM or USFS will be applied to the identified noxious weed populations on BLM- or USFS-

administered land. As described in Section B2.6 – Pesticide Application, Handling, Spills, and Cleanup,

pesticide applications will be controlled to minimize the impacts on the surrounding vegetation. In areas

of dense noxious weed populations, a broader application will be used and a follow-up seeding program

will be implemented.

Reclamation Actions

As specified in Appendix C1 – Reclamation, Revegetation, and Monitoring Plan Framework, in areas

where weed control measures have been implemented and require postconstruction reclamation actions

the following specific stipulations and methods are applicable:

NW-15 If areas are not immediately seeded after construction, due to weather or scheduling

constraints, all noxious weeds will be treated before seeding, preferably in the spring.

NW-16 If discing or tilling is an appropriate and feasible treatment method, it will only be

permitted in bladed areas.


NW-17 Seed selection will be based on site-specific conditions and the appropriate agency-

approved seed mix will be identified for those conditions based on the presence and

treatment of noxious weeds in the Project area. The CIC or weed specialist may

recommend modified seeding application rates and timing of implementation to achieve

site-specific weed management objectives.

NW-18 Additional weed and/or erosion control measures recommended during monitoring will

follow the preventive and control measures outline in this plan. Continued cooperation with

the current BLM or USFS noxious weed coordinator and local weed management areas

also is encouraged.

Agency Specific Requirements

The Wyoming, Colorado, and Utah State Departments of Agriculture each regulate noxious weed control

under respective noxious weed statues, which mandate property owners must control noxious weeds on

their land and property. Pest management, including noxious weed control, must be intended for

prevention, eradication, rehabilitation, control, or containment efforts as required by the state statutes.

Through the implementation of this plan and in conjunction with the BLM and USFS (as described

below), the Project will be in compliance with Wyoming, Colorado, and Utah noxious weed statues. The

following is a discussion regarding BLM and USFS stipulations, as well as personnel and equipment

requirements.

Bureau of Land Management and U.S. Forest Service

The Final Programmatic Environmental Impact Statement on Vegetation Treatments Using Herbicides

on BLM Land in Seventeen Western States lists pesticides acceptable (refer to Attachment B – Agency-

approved Pesticides) for use on BLM-administered lands (BLM 2007). Pesticides and adjuvants listed in

Table 1 – Pesticides Approved for Use on Bureau of Land Management-Administered Lands in

Wyoming, Colorado, Utah and Table 3 – Adjuvants Approved for Use on Bureau of Land Management-

Administered Lands in Wyoming, Colorado, and Utah of Attachment B – Agency-approved Pesticides

may be used in the Project area on BLM-administered lands after coordination with the CIC. In addition,

BLM-approved pesticide application rates are listed in Table 2 – Pesticide Formulation Application Rates

Approved for Use on Bureau of Land Management-Administered Lands in Wyoming, Colorado, and

Utah of Attachment B – Agency-approved Pesticides. The Environmental Assessment for Control of

Noxious Weeds and Other Undesirable Vegetation on the Uinta National Forest lists pesticides

acceptable for use on lands administered by the Uinta National Forest (USFS 1994). Table 4 – Approved

Pesticide Formulations and Application Rates for Use on Lands Administered by the Uinta National

Forest in Attachment B – Agency-approved Pesticides includes the pesticide recommendations for the

Uinta National Forest. The pesticides approved for use on the Project will be reviewed and approved by

the BLM and USFS prior to beginning construction. Guidelines for use of chemical control of vegetation

on BLM-administered lands are presented in BLM Manual 9011 – Chemical Pest Control. Guidelines for

use of chemical control of vegetation on USFS-administered lands are presented in Forest Service Manual

2150 – Pesticide-Use Management and Coordination. These guidelines require submittal of a Pesticide

Use Proposal, which will be prepared by the Company/Construction Contractor(s) and submitted to the

BLM and/or USFS for review and approval prior to initiation of construction activities. Once approved,

any use of other pesticides will require pesticide application records that detail the use and application.

The pesticide application records will then be submitted to the BLM and/or USFS in a timely manner.

The occurrence of noxious weeds in the Project area will be reported to the applicable BLM district

(field) office(s) and/or USFS Ranger District Office(s) in whose jurisdiction the weeds occur. The

appropriate weed control procedures, including target species, timing of control, and method of control,

will be determined in consultation with the BLM and USFS by the Company/Construction Contractor(s)

based on the procedures outlined in this Noxious Weed Management Plan. The Company may be able to


take advantage of any existing cooperative agreements between the BLM and/or USFS and the counties

by providing the funds required for county personnel to implement the necessary weed control

procedures. If not, the Company will be responsible for providing the necessary personnel or hiring a

contractor to implement the weed control procedures with the qualifications as described in Section

B2.4.1.1 – Weed Management Personnel Requirements. All Project-related weed control activities will be

developed and coordinated by the Company/Construction Contractor(s) in accordance with local BLM

and USFS management requirements. The following stipulations are applicable:

NW-19 Pesticide use is not authorized in areas that contain the following biologically sensitive

habitats:

To be developed in coordination with the agencies upon completion of biological

resource surveys.

NW-20 The use of pesticides for vegetation management and noxious weed control shall be limited

to hand application methods that target individual plants, within 500 feet of sensitive plant

occurrences unless otherwise approved by the respective federal land-management

agencies’ Authorized Officers or their designated representatives. Weed management

within 500 feet of sensitive plant occurrences shall occur under the supervision of a

qualified botanist to ensure general pesticide is not used in or near sensitive plant

occurrences.

NW-21 If previously unknown sensitive biological resources are located during weed control

operations, operations will cease and federal land-management agencies will be notified

immediately.

NW-22 Equipment and vehicles planned for use in identified habitat for sensitive plants or wildlife

species habitat will be cleaned with compressed air or water before entering occupied

habitat to minimize the spread of noxious weeds and other undesirable vegetation.

NW-23 Pesticides and application rates used on BLM- and USFS-administered lands must be

consistent with local management and may differ relative to specific field office and/or

district office guidelines.

NW-24 Material (soil, gravel, etc.) transported from offsite locations is required to be weed-free

and approved by the appropriate lead agency. This measure may require additional permits

and/or certification for the material, depending on the source.

B2.5 Monitoring

A weed management specialist, contracted by the Company, will monitor the Project and any other areas

of disturbance associated with the Project. Monitoring will be conducted biannually during the spring and

fall for 5 years (where required by land-management agencies, states, counties, and private land owners)

following completion of reclamation activities. This monitoring will coincide with seasons when the

species identified during preconstruction inventories may be identified in the field. This monitoring may

coincide with the reclamation monitoring identified and outlined in Appendix C1 – Reclamation,

Revegetation, and Monitoring Plan Framework. Growing seasons will vary from year-to-year; therefore,

the length of monitoring will vary as well.

B2.5.1 Reclamation Monitoring

During Reclamation Monitoring, the Construction Contractor(s) for the Company will initiate monitoring

of previously identified affected/disturbed areas during the first spring following construction and proceed

with monitoring during subsequent intervals. Monitoring will occur in all areas where the Project has a


high risk of introducing or spreading noxious weeds, including weed wash stations and areas of ground

disturbance or vegetation clearing.

Noxious weed monitoring will occur biannually for 5 years following completion of each segment of the

Project. In addition, noxious weed conditions will be included in the evaluations of revegetation success

as described in Appendix C1 – Reclamation, Revegetation, and Monitoring Plan Framework. The

Company will document its observations following the above-noted field inspections and make these

monitoring reports available to the BLM, USFS, and counties as required.

In the event that sensitive plant occurrences are affected by Project activities, these plant occurrences will

be monitored annually for the first 5 years following Project implementation. Individual counts of

sensitive plants will be undertaken in affected areas to determine whether the sensitive plants are

recolonizing the site. An annual report with photos from permanent photo plots, individual plant counts in

the affected areas, and noxious weed presence and treatment data will be provided to the appropriate

BLM and/or USFS district (field) office(s).

Areas where the spread of noxious weeds are noted, particularly in previously unaffected locations, will

be further evaluated to determine if these areas require remedial action and additional treatment. The

Company will identify such areas to the agencies by state, county, and milepost (or nearest transmission

structure number) and will record any additional noxious weed control treatments. A report summarizing

right-of-way stability, revegetation progress, percentage of cover, and weed populations will be provided

to the BLM and USFS as described in Appendix C1 – Reclamation, Revegetation, and Monitoring Plan

Framework.

B2.5.2 Ongoing Monitoring and Control

The Company will be responsible for ongoing weed monitoring and control inside of the right-of-way for

the life of the BLM right-of-way grant and USFS special-use authorization. The Company will consult

with the BLM, USFS, and counties should they have a concern pertaining to noxious weeds in their

jurisdiction. The BLM or USFS also may contact the Company to report on the presence of noxious

weeds. The Company will be required to monitor and control noxious weeds at a level that does not

exceed the density or extent of their conditions identified during preconstruction surveys for the full term

of the BLM right-of-way grant/USFS special-use authorization/Bureau of Indian Affairs encroachment

permit and grant of easement and will eradicate any new population that is demonstrated to be the result

of Project construction, operation, or maintenance.

The Company will not be responsible for the eradication of pre-existing noxious weed populations or new

or recurring noxious weed populations caused by the spread of noxious weeds from adjacent lands. Also,

the Company will not be responsible for noxious weeds introduced into the Project area by activities other

than Project construction, operation, and maintenance.

Operations personnel will be trained in the identification of predominant noxious weed populations, and

the Company will control the weeds on a case-by-case basis in consultation with the BLM and USFS, as

appropriate. If determined necessary, a report on actions taken will be provided in the form of Monitoring

Reports to the BLM and USFS on a predetermined schedule.

B2.6 Pesticide Application, Handling, Spills, and Cleanup

B2.6.1 Pesticide Application and Handling

The list of pesticides to be used will be reviewed and approved by the BLM and USFS, and pesticide

application will be based on information gathered from the BLM, USFS, and state noxious weed


authorities. The Project-approved pesticides are listed in Attachment B – Agency-approved Pesticides.

Before application, all required permits from local authorities will be obtained (BLM, USFS, and/or state

noxious weed authorities). Permits may contain additional terms and conditions that go beyond the scope

of this management plan. Additional information regarding use, storage, and disposal of pesticides can be

found in Appendix C4 – Hazardous Materials Management Plan Framework.

NW-25 A certified pesticide applicator, approved in the state where pesticide is to be applied, will

perform the application using pesticides selected and approved by the BLM or USFS in

accordance with applicable laws, regulations, and permit stipulations. All pesticide

applications must follow U.S. Environmental Protection Agency label instructions.

Application of pesticides will be suspended when any of the following conditions exist:

Wind velocity exceeds 6 miles per hour during application of liquids.

Wind velocity exceeds 15 miles per hour during application of granular pesticides.

Snow or ice covers the foliage of noxious weeds.

Precipitation is occurring or is imminent.

NW-26 Vehicle-mounted sprayers may be used in open areas readily accessible by vehicle. Hand-

application methods that target individual plants will be used to treat small or scattered

weed populations in rough terrain and in areas within 500 feet of sensitive plant

occurrences. Calibration checks of equipment will be conducted at the beginning and

periodically during spraying to ensure proper application rates are achieved.

NW-27 Pesticides will be transported to the Project site daily with the following provisions:

Only the quantity needed for that day’s work will be transported.

Concentrate will be transported only in approved containers in a manner that will

prevent tipping or spilling and in a location isolated from the vehicle’s driving

compartment, food, clothing, and/or safety equipment.

Mixing will be done offsite over a drip-catching device and at a distance greater than

400 feet from open or flowing water, wetlands, or other environmental resources. No

pesticides will be applied at these areas unless authorized by appropriate regulatory

agencies.

All pesticide equipment and containers will be inspected for leaks daily.

Disposal of spent containers will be in accordance with the pesticide label and will

adhere to the methods prescribed in Appendix C4 – Hazardous Materials Management

Plan Framework.

NW-28 Pesticides may not be applied over surface water. Only pesticides registered for use near

water will be used within 328 feet (100 meters) (Utah and Colorado) or 500 feet (153

meters) (Wyoming) of surface water or in areas with a high leaching potential. Minimum

pesticide spray distances (buffers) from live water are as follows:

Backpack spraying operations – 20 feet

Other mechanized applications – 50 feet

B2.6.2 Pesticide Spills and Cleanup

All reasonable precautions will be taken to avoid pesticide spills.

NW-29 In the event of a spill, cleanup will be immediate. The Construction Contractor(s) will keep

spill kits in their vehicles and in pesticide storage areas to allow for quick and effective

response to spills. Items to be included in the spill kit are:

Protective clothing and gloves


Absorptive clay, “kitty litter,” or other commercial absorbents

Plastic bags and a bucket

Shovel

Fiber brush and screw-in handle

Dust pan

Caution tape

Detergent

NW-30 The response to a pesticide spill will vary with the size and location of the spill, but general

procedures include:

CIC, BLM, and/or USFS notification

Traffic control

Dressing the cleanup team in protective clothing

Stopping any leaks

Containing spilled material

Cleaning up and removing spilled pesticide and contaminated absorptive material and

soil

Transporting spilled pesticide and contaminated material to an authorized disposal site

B2.6.3 Worker Safety and Spill Reporting

NW-31 Pesticide contractors will be state certified to apply pesticides and must both obtain and

possess readily available copies of the appropriate material safety data sheets for the

pesticides used. All pesticide spills will be reported in accordance with applicable laws and

requirements.

Additional information regarding the handling of hazardous materials may be found in Appendix C4 –

Hazardous Materials Management Plan Framework and additional information regarding spills may be

found in Appendix C3 – Spill Prevention, Containment, and Countermeasures (SPCC) Plan Framework.

ATTACHMENT A – NOXIOUS WEED OCCURRENCES

Noxious weed occurrence information derived from lead agency field office management documents,

where available, was used to determine the presence of noxious weeds in the Project area. Specific

information about noxious weed species presence in the Project area in Colorado is not available. A

preconstruction survey for noxious weeds using the protocol established by the BLM Integrated Weed

Management Manual 9015 will be conducted by qualified personnel retained by the

Company/Construction Contractor(s) and in consultation with the Project CIC before Project operations

begin. The information collected during this survey will supplement the information contained in this

document.
