APPENDIX D WEED CONTROL STANDARDS AND PROJECT CRITERIA

Standard Operating Procedures, Best Management Practices, Design Features, and Monitoring

SOPs and Special Design Features Standard Operating Procedures (SOPs) are the management controls and performance standards intended to protect and enhance natural resources that could be affected by vegetation treatments including the use of herbicides. The BLM will follow SOPs to ensure that risks to human health and the environment from herbicide treatment actions and other vegetation treatments are kept to a minimum. Herbicide treatment SOPs are described in Table 2-8, pages 2-30 to 2-35 and Appendix B of the ROD to the PEIS (USDI-BLM 2007a) and Appendix A of the ROD to the Vegetation Treatments using Aminopyralid, Fluroxypyr, and Rimsulfuron EIS (PEIS 2016).

The decision to use the new herbicides approved in the 2016 PEIS is supported by herbicide treatment SOPs and mitigation measures to ensure that the natural and human environment are protected during implementation of herbicide treatments. Herbicide treatments would follow BLM procedures outlined in BLM Handbook H-9011-1 (Chemical Pest Control), and manuals 1112 (Safety), 9011 (Chemical Pest Control), and 9015 (Integrated Weed Management), and all applicable

-BLM

2007a). The BLM would comply with changes in label directions and with all state registration requirements. The active ingredients and formulations approved for use would only be applied for uses, and at application rates, specified on the label directions.

Herbicide application schedules would be designed to minimize potential impacts to non-target plants and animals, while remaining consistent with the objective of the vegetation treatment program. The application rates depend upon the target species, the presence and condition of non-target vegetation, soil type, depth to the water table, presence of other water sources, and the label requirements. The application method chosen depends upon the treatment objective (removal or reduction); accessibility, topography, and size of the treatment area; characteristics of the target species and the desired vegetation; location of sensitive areas and potential environmental impacts in the immediate vicinity; anticipated costs; equipment limitations; and meteorological and vegetative conditions of the treatment area at the time of treatment.

Special design features and best management practices would be incorporated where applicable for the prevention and treatment of noxious weeds when authorizing new permitted/ authorized activities. These practices or combinations of practices are considered to be the most effective means of preventing or reducing the amount of disturbance or impact to a resource. A list of the practices that would be implemented as part of the action alternatives to reduce the potential for impacts to resources is presented below.

Standard Operating Procedures for Herbicide Use herbicide label. This section warns of known pesticide risks to the environment and provides practical ways to avoid harm to organisms or to the environment.

Avoid accidental direct spray and spill conditions to reduce the largest potential impacts.

A spill cleanup kit will be available whenever pesticides (herbicides) are transported or stored.

D-2

A spill contingency plan will be developed prior to all herbicide applications. Individuals involved in herbicide handling or application will be instructed on the spill contingency plan and spill control, containment, and cleanup procedures.

Use the typical application rate, rather than the maximum application rate, to reduce potential risk to most species for most herbicides.

Herbicide will be applied to the smallest area possible to achieve control of the target species.

Notify adjacent landowner(s) prior to treatment.

Apply an aerial buffer zone of 300 feet to cropland or residents/private land.

Prior to helicopter fueling operations prepare a transportation, storage, and emergency spill plan and obtain the appropriate approvals; for other heavy equipment fueling operations use a slip-tank not greater than 250 gallons. Prepare spill containment and cleanup provisions for maintenance operations.

Within 300 feet of wetlands or riparian areas, do not fuel/refuel aerial equipment, store fuel, or perform equipment maintenance (locate all fueling and fuel storage areas, as well as service landings outside of protected riparian areas).

Clean equipment, vehicles, and clothing of personnel to remove weed seeds/materials.

Use weed-free feed for horses and pack animals involved in weed control efforts and weed- free straw and mulch for stabilization and rehabilitation activities.

Only those herbicides officially approved for use on BLM-administered lands in Idaho (2007 PEIS and 2016 PEIS) and labeled for application on rangelands would be utilized.

The herbicides approved for use on BLM-administered lands in Idaho are listed in Appendix A. Weed species listed in Appendix E would be targeted for control and/or eradication.

All proposed herbicides would be handled and applied in strict accordance with all label restrictions and precautions, as well as applicable BLM Policy. In instances where herbicide labels, federal, or state stipulations overlap, the more restrictive criteria would be adhered to. Selection of an herbicide for site-specific weed control would depend on its effectiveness on a particular weed species, success in previous similar applications, habitat types, soil types, and nearness of water and private property.

Application of any herbicide to treat weeds would be performed by or supervised by a state or federal licensed applicator. These applicators are responsible for complying with all applicable Federal, State, and county laws, codes, regulations, design features, and SOPs related to the use of weed control herbicides. This includes BLM, County, or State personnel or their contractors.

All applicators would comply with safety requirements, including personal protective equipment, spray equipment, herbicide labels and rates, and environmental concerns. All contractors and county agreement applicators are responsible for the cleanup of hazardous materials released on public lands, if they are at fault. All weed control efforts done by BLM personnel or their authorized agents would be done in accordance with the applicable Safety Plan and the Storage, Transportation and Spill Contingency Plans.

Emergency response kits and trained personnel would be available and on-site whenever herbicides are transported or stored.

D-3 orted from storage/mixing areas to application sites.

If appropriate coordinate with field office Archaeologist and appropriate Native American tribe during treatment planning, and if necessary include pre-treatment surveys for habitat and species used for tribal treaty rights within or adjacent to proposed treatment areas.

No ground based spraying of any herbicide would occur when wind velocity exceeds 10 mph, as per State of Idaho Department of Agriculture standards, or as indicated in the Special Design Features listed below.

Aerial herbicide application would not occur when sustained wind speeds exceed 5 mph or label recommendations, whichever is less.

Aerial herbicide applications would not occur during inversions, or below minimum relative humidity or above maximum temperature, as stated on label.

Prior to commencing a spray operation a weather forecast for the area would be obtained. During application, weather conditions would be monitored at spray sites (i.e., wind speed, temperature, and relative humidity). Additional weather and application monitoring would occur whenever a weather change may impact safe placement of the herbicide on the target area.

All aerial herbicide applications would be conducted in a manner that avoids application overlap and drift.

Aerial herbicide application would be used to control or eradicate large infestation of weeds or in areas that have steep slopes, rocky soils, and are difficult to access.

Make helicopter applications at a target airspeed of 40 to 50 mph and less than 45 feet above ground.

Aerial spray units (and perennial seeps, ponds, springs, and wetlands in proposed aerial units) will be identified prior to spraying to ensure only appropriate portions of the unit are aerially treated. A global positioning system (GPS) will be used in spray helicopters and each treatment unit will be mapped before the flight to ensure that only areas marked for treatment are treated. Drift monitoring cards may be placed within 300 feet from and perpendicular to perennial streams to monitor levels of herbicide drift.

Aerial herbicide application will not occur in designated municipal watersheds. Idaho Department of Environmental Quality (IDEQ) Source Protection Areas will not be included in aerial application project areas.

Aerial herbicide application will not occur over areas with >30% live tree canopy cover.

Dyes may be used to obtain uniform coverage. This would help prevent under or over treatment/application skipped areas, and help with detection of drift. It would also reduce the risk of treating non-target species.

All colorants used will be non-toxic, water-soluble, liquid formulations.

Herbicide applications would be implemented in a manner to avoid off site movement of herbicides either through the air, through soil, or along the soil surface. Project site terrain, soil type, and vegetation would be taken into consideration when selecting herbicide type, application method, and application timing.

D-4

Areas that pose exposure risk would be posted to warn the public of herbicide use and hazards.

Ground-spraying with backpack pumps, spraying from a pumper unit on the back of a pickup truck or an OHV, or pack animals to transport and apply herbicides in more rugged terrain. Ground based application would occur in smaller, fragmented patches of weeds where herbicide treatment is the most effective means of controlling or eradicating weeds.

A combination of herbicides may be used when it is determined that this is the most effective way to control multiple weed species, or when mixing of herbicides are more effective on weed species. All herbicide combinations would conform to label guidelines for mixing.

All pesticide labels will be strictly enforced and other restrictions including the following:

a. Refer to Table 4 for maximum wind speed restrictions by herbicide application method.

b. Do not spray if precipitation is occurring or is imminent.

c. Do not spray if air turbulence is sufficient to affect the normal spray pattern.

d. Do not spray if snow or ice covers the target foliage.

e. No carrier other than water will be used.

Annual Operating Plans for noxious weed control on public lands will integrate PACFISH/INFISH Riparian Management Objectives, standards and guidelines; RA-3, RA-4, RA-5, WR-2, WR-3, WR-4, FW-l.

Dyes will be used in riparian areas to provide visual indication of herbicide coverage.

A 150-foot buffer from live waters, riparian areas (i.e. possessing vegetation consistent with hydric soils), or soils over shallow water tables (i.e. supersaturated soils) is required for use of any upland herbicide with a soil half-life greater than 365 days. Expiration of the soil half-life is required prior to repeated treatment of the area with the same upland herbicide.

Sampling of aerial spray projects may be accomplished through the use of spray cards, dye or other type of indicator. The purpose of this monitoring will be to validate buffer effectiveness for riparian areas and water edges. Findings from these indicators will be included with the annual monitoring results.

Aerial application equipment will be designed to deliver a median droplet diameter of 300 to 800 microns. This droplet size is large enough to avoid excessive drift while providing adequate coverage of target vegetation.

A maximum of 20,000 acres would be treated annually not to exceed 10,000 acres aerially and no more than 5,000 acres treated within riparian habitats utilizing ground based methods.

No more than 25% of total acreage within each 6th field HUC would be treated annually, with no more than 1000 acres treated in riparian.

In order to prevent herbicide and adjuvants from entering water, check local weather conditions daily, monitor site-specific conditions during herbicide application, select the most suitable herbicide and adjuvants (as appropriate) combination for the setting and apply the lowest effective use rates, employ spot spraying techniques in riparian areas, apply herbicide at low pressure, use the largest appropriate nozzle size and other appropriate

D-5 equipment, add drift control agents where necessary, and utilize directional application techniques to direct herbicide away from water.

The BLM proposes to use only Washington State aquatic-certified adjuvants (e.g., deposition aid, surfactant, dye) in riparian areas (see table D-1).

Standard Operating Procedures for Using Biological Agents

The use of biological control agents would be conducted in accordance with BLM procedures outlined in The Use of Biological Control Agents of Pests on Public Lands (BLM 1990). Only those biological agents that have been tested and approved by APHIS would be released on public lands.

Using sheep, goats, or cattle as a biological control agent would follow criteria listed below:

No sheep or goats would be used in mapped Bighorn sheep habitat All cattle use would follow current grazing permit restrictions Obtain Animal and Plant Health Inspection Service (APHIS) permit to Move Live Plant

Pests, Noxious Weeds, or Soil for those agents when transportation across state lines is involved.

Use only APHIS and State of Idaho approved biological control agents.

To the extent practicable, collect biological control agents locally or from areas with similar climatic and weather conditions, land and soil types, and cover types to maximize successful establishment.

Distribute biological control agents at the optimal season and life cycle stage to optimize the likelihood of successful establishment. Distribute quantities sufficient to optimize successful short-term establishment. For those agents that self-disperse poorly, actively assist the distribution throughout target infestations by redistribution (collecting and moving the agent to new locations).

For those agents that self-disperse poorly, actively assist the distribution throughout target infestations by redistribution (collecting and moving the agent to new locations).

Standard Operating Procedures for Revegetation

Natural revegetation is the preferred option whenever possible. Invasive plant-infested sites or areas of disturbance (e.g., wildfire) will be assessed to determine if the area is capable of natural recovery after invasive plant treatments.

When working in watersheds with ESA-listed species, mechanical ground disturbing activities will not be conducted adjacent to or within riparian areas during the spawning season.

A 25 foot buffer will be maintained next to live water to leave ground cover intact and prevent erosion into streams or adjacent waterbodies.

D-6

Limit mechanical treatments to power tools that do not disturb the ground when working within 25 feet of streambanks, or floodprone areas along lakes, ponds, springs, and seeps.

Disking, plowing, or blading would not occur within appropriate buffer zones surrounding riparian areas as decided by an ID Team. Distances identified for PACFISH/INFISH will be followed when determining buffer zone width.

Limited to invasive plant infestation areas with a maximum 50 acres per location.

Use native or sterile seed/seedlings when possible.

If it is determined that non-native species are the best choice for interim or permanent revegetation, be sure to select species that do not behave invasively under conditions similar to those at the site to be revegetated.

Conduct rehabilitation and restoration activities only in areas with low or moderate land type erosion hazard ratings.

Equipment will be pressure washed prior to and following implementation to avoid introduction and/or spread of invasive plants.

Evaluate options, including closure from livestock or human disturbance, until seeding is established successfully.

Prescribed fire would only be used for revegetation when the thatch layer of annual grasses was too copious for seed/chemical/etc. for good soil contact and would conform to all other standard operating procedures for revegetation.

A site-specific burn plan would be developed prior to any prescribed fire actions.

Design Features to Protect Cultural Resources

The SFO or CFO Archaeologist or his/her qualified representative would assess and record cultural sites to determine appropriate protective measures prior to weed treatment measures that would affect historic properties.

A Class III Cultural Resources inventory would be conducted prior to any weed treatment activities that could potentially affect cultural resources. If historic properties are discovered they would be avoided as stipulated by the CFO or SFO Archaeologist.

If weed treatment measures cannot avoid historic properties, the CFO or SFO Archaeologist would develop and complete appropriate mitigation measures prior to planned surface disturbing activities. These plans would be developed and executed in cooperation with SHPO and appropriate Native American groups and interested individuals.

The following provisions would be included in weed treatment actions that affect cultural

Manager, by telephone, with written confirmation, immediately upon the discovery of human remains, funerary objects, sacred objects, or objects of cultural patrimony on federal land.

Pursuant to 43, CFR 10.4(c), the Project Supervisor must immediately stop any ongoing activities connected with the discovery, and make a reasonable effort to protect the

D-7

Design Features for Special Designation Areas including Wilderness, Wilderness Study Areas, and Areas of Critical Environmental Concern

Invasive plant treatments within designated wilderness would follow the direction contained in BLM Manual 6340 Management of Designated wilderness Areas. These applications will undergo the appropriate Minimum Requirements Analysis and will use the Minimum Requirements Decision Guide as described in BLM Manual 6340.

In addition to the direction found in BLM Manual 6340, invasive plant treatments would follow direction contained within the specific wilderness Management Plan (WMP) in which the treatment is occurring. These plans for designated wilderness within the CFO are currently being prepared.

Invasive plant treatments within wilderness Study Areas (WSA) will follow the direction contained in BLM Manual 6330 Management of wilderness Study Areas.

Motorized equipment will not be used for ground-based herbicide applications in wilderness

Use herbicides only when they are the minimum method necessary to control invasive plants and give preference to herbicides that have the least impact on non-target species.

Implement herbicide treatments during periods of low human use.

Invasive plant treatments would be conducted in a manner to allow for natural revegetation.

Research and demonstration will not occur in special designation areas.

Design Features for Protecting Riparian Areas, Including occupied T& E Fish Habitat

Treatment activities including ground-based spraying, manual, mechanical or biological treatments may occur within designated Riparian Habitat Conservation Areas as defined by INFISH/PACFISH.

Disking, plowing, or blading would not occur within appropriate buffer zones surrounding riparian areas as decided by an ID Team. Distances identified for PACFISH/INFISH will be followed when determining buffer zone width.

Soils that are fully saturated would not be disturbed or only minimally disturbed.

In locations adjacent to streams where sediment has been identified, through the Total Maximum Daily Load (TMDL) process, as an instream pollutant, an ID Team would determine whether additional best management practices for erosion control would be required.

No spraying of picloram would be authorized within 50 feet of any live waters or shallow water tables.

Use only Washington State Department of Ecology approved aquatic adjuvants (e.g.

deposition aid, surfactant, Dye (non-toxic, water-soluble liquid formulations) would be used in all riparian spray treatments.

Equipment used for transportation, storage, or application of chemicals shall be maintained in a leak proof condition.

D-8

No herbicide mixing will be authorized within 100 feet of any live waters. Mixing and loading operations must take place in an area where an accidental spill would not contaminate a stream or body of water before it could be contained.

Equip drafting equipment with back siphoning prevention devices.

Within 25 feet of live waters or areas with shallow water tables, only approved riparian herbicides (Table 4) would be used; appropriate methods of control include backpack sprayer, hand pump sprayer, wicking, wiping, dripping, painting, or injecting.

Only ground based spot/selective applications of herbicides rated as having a low or moderate risk levels for aquatic species (Table 4) will be authorized for use 25 to 50 feet from live waters. Authorized spray equipment will include vehicle mounted spray rigs (hand-held sprayer only), backpack sprayer, hand pump sprayer, and wicking (e.g., also includes wiping, dipping, painting, or injecting target species).

If it is necessary to use boats to reach a treatment area, the only mixed herbicides to be transported over water will be those that do not contain picloram. Picloram will only be transported in an appropriately sealed and labeled container, and will be mixed >100 feet from live or seasonal waterways. Extreme caution will be used while loading and unloading herbicides and spray equipment to minimize the potential for contamination of the water.

Herbicides would be transported in water-tight, floatable containers. When possible, the boat would be grounded before loading or unloading at the destination.

Hydrologically connected roadside ditches, which occur within the 50 foot riparian buffer, will only be treated with approved riparian herbicides (Table 4). If a hydrologically connected ditch is wet it will be treated as a riparian area and only approved riparian herbicides can be used for treatments; hydrologically connected roadside ditches will not be sprayed for at least 24 hours before a predicted rain event (high probability from current forecast).

Manual control (e.g., hand pulling, grubbing, cutting, etc.) is authorized in all areas, and may be used in sensitive areas to avoid adverse effects to non-target species or water quality. All noxious weed disposals will be in accordance with proper disposal methods.

Aquatic formulations of 2,4-D amine, glyphosate, aminopyralid, imazapyr, and triclopyr TEA shall be used within 50 feet of live water.

No aerial application will take place within the following buffers:

o 300 feet T&E fish streams o 300 feet fish bearing waters.

o 300 feet perennial, non-fish bearing waters.

o 300 feet intermittent stream channels with live water.

o 300 feet ponds, lakes, springs, wetlands.

o 300 feet intermittent stream channels that are dry.
