The Contractor shall provide the location of any staging areas, helicopter landing zones, or other use areas that have not already been approved no later than 30 calendar days after receipt of the notice to proceed. The Government will have 60 calendar days from receipt of the request to obtain environmental approval. If the Government cannot provide formal environmental approval by the 60 day deadline, only Western cleared locations will be permitted for Contractor use.

The following are measures that must be adhered to in order to avoid biologically sensitive resources. If the Contractor expects that project activities will occur within the buffers described, then the Contractor shall inform Westerns biologist at least 2-weeks prior to activities so that Western may schedule a biological monitor. In addition to these measures, the Contractor shall adhere to any biological measures resulting from consultation with the U.S. Fish and Wildlife Service (USFWS) and other regulatory agencies. Measures determined through consultation with the USFWS and other regulatory agencies will supersede the measures detailed below.

Prior to the start of project activities, all personnel shall participate in environmental awareness training which will inform them of the sensitive habitats within the project area, the species that have the potential to occur in the project area, and the avoidance and minimization measures that are to be adhered to during project activities. Any new crew members that start after project activities have commenced will be given the environmental awareness training within 1-day of working onsite.

Vernal Pool Branchiopods (Fairy Shrimp) and Vernal Pool Plants:

Prior to project activities, Western will identify and flag vernal pools, swales, wetlands, and other vernal pool branchiopod/plant habitat within 250-feet of pulling and tensioning sites, landing zones, staging areas, pole installation, removal, and modification areas, and off-road access areas. Project activities within 250-feet of vernal pool branchiopod/plant habitat shall be avoided to the extent possible. If project activities must occur within 250-feet of vernal pools or other vernal pool branchiopod habitat, then a Western supplied biological monitor will flag the work area limits for the site and will remain onsite during all activities within 250-feet of such habitat to ensure that the buffer is not encroached upon. Entrance into or disturbance of vernal pools, swales, wetlands, and other fairy shrimp habitat may only be done with feature specific approval from Western’s biologist, with a biological monitor on site, and with mitigation for the feature in place.

Unless feature specific approval from Western’s biologist is obtained, a minimum buffer of 100-feet during the wet season (generally October 1 to May 31) and 50-feet during the dry season (generally June 1 to September 30) shall be maintained from the edge of vernal pools, swales, wetlands, and other vernal pool branchiopod/plant habitat and the feature will be protected from siltation and contaminant run-off by use of erosion control. Erosion control materials will be of a tightly woven natural fiber netting or similar material that will not entrap reptiles and amphibians (e.g., coconut coir matting). Monofilament plastics shall not be used for erosion control near vernal pools and seasonal wetlands. Erosion control measures shall be placed between the outer edge of the buffer and the activity area. All fiber rolls and hay bales used for erosion control shall be certified as free from noxious weed seed, and shall be composed of native species or sterile nonnative species.

All equipment shall be stored, fueled, and maintained in a vehicle staging area 300-feet or the maximum distance possible from any vernal pool, vernal pool grassland, or seasonal wetland, and no closer than 200-feet unless a bermed (no ground disturbance) and lined refueling area is constructed and hazardous-material absorbent pads are available in the event of a spill. Vehicles shall be inspected daily for fluid leaks before leaving the staging area.

Valley Elderberry Longhorn Beetle (VELB):

Prior to project activities, a Western supplied biologist will flag a 100-foot buffer from the dripline of any elderberry shrub in the vicinity of pulling and tensioning sites, landing zones, staging areas, pole installation, removal, and modification areas, and off-road access areas. Project activities within this buffer shall be avoided to the extent possible. If project activities must occur within 100-feet of an elderberry shrub, then a biological monitor will remain onsite during all activities within 100-feet of an elderberry shrub and activities will not take place during VELB’s active period (April to June). With the exception of vehicle travel along previously established roads, project activities will not be permitted within 20-feet of an elderberry shrub without shrub specific approval from Western’s biologist. A 20-foot buffer will be flagged or fenced around the dripline of elderberry shrubs within the right-of-way as feasible. Fencing or flagging will be installed immediately adjacent to the dirt roadway for those shrubs that are within 20-feet of an existing dirt roadway.

Installation of conductor shall be performed by pulling the line from tower to tower without touching the vegetation in areas where elderberry shrubs are present.

Listed Fish Species:

(a) Pulling and tensioning sites, landing zones, staging areas, pole installation, removal, and modification areas, and off-road access areas shall be located at least 200-feet away from aquatic habitat suitable for listed fish species. If activities must occur within this buffer, then a Western supplied biological monitor will be present for all activities within 200-feet of fish habitat. Installation of the conductor shall be performed by pulling the line from tower to tower without touching water bodies. No project activities shall occur within habitat for listed fish species.

Migratory Birds And Raptors:

(b) Under the Migratory Bird Treaty Act of 1918, migratory bird species and their nests and eggs are protected from injury or death. Impacts to migratory bird nests (including state listed Swainson’s hawk, other raptors, and state listed bank swallow, burrowing owl, yellow warbler, yellow breasted chat, bald eagle, and California black rail) shall be avoided during the nesting season (February 1 to August 31). If project activities occur during the nesting season, Western will survey the project area for migratory bird nests prior to project activities and establish appropriate buffers around any nests that may potentially be disturbed. If work must be conducted within these buffers, a Western supplied biological monitor will be onsite for project activities within the buffers. If the biological monitor determines that activities are likely to cause nest impacts or nest abandonment, then project activities in the area shall be postponed until nestlings have fledged or the nest is no longer active.

Burrowing Owl:

(c) Western will conduct pre-construction surveys for all pulling and tensioning sites, landing zones, staging areas, pole installation, removal, and modification areas, and off road access areas within 30-days prior to the start of project activities and identify and flag active burrowing owl burrows within 250-feet of these areas. Activities within 250-feet of active burrows shall be conducted between September 1 and January 31 (outside of the burrowing owl nesting season) and a Western supplied biological monitor will be present for such activities. If the biological monitor determines that activities are likely to cause nest impacts or nest abandonment, then project activities in the area shall be postponed until nestlings have fledged or the nest is no longer active.

Swainson’s Hawk:

(d) Western will conduct pre-construction surveys for all pulling and tensioning sites, landing zones, staging areas, pole installation, removal, and modification areas, and off road access areas within 30-days prior to the start of project activities for activities occurring between April 1 and August 31. A buffer of 0.25 miles will be established and maintained around active Swainson’s hawk nests until a qualified biologist determines that activities will not adversely affect adults or young. This buffer may be adjusted, as assessed by a qualified biologist, based on changes in sensitivity exhibited by birds over the course of the nesting season or type of project activity. Activities within 0.25 miles of an active Swainson’s hawk nest may be limited to one consecutive day of work at a time and minimal vehicle and equipment activity. Other measures to avoid Swainson’s hawk nest disturbance will be taken as necessary.

Waters Habitat:

The following activities will be prohibited within 100-feet of a seep, spring, pond lake, river, stream, or marsh, and their associated habitats:

Vehicle access, except on existing access and maintenance roads.

Dumping, stockpiling, or burying of any material.

Mixing of pesticides, herbicides, or other potentially toxic chemicals.

Open petroleum products.

All equipment shall be stored, fueled, and maintained in a vehicle staging area 300-feet or the maximum distance possible from any seep, spring, pond, lake, river, stream, marsh, wetland, or their associated habitats. Vehicles shall be inspected daily for fluid leaks before leaving the staging area.

For ground-disturbing activities, a 100-foot buffer zone shall be maintained from the edge of seeps, springs, ponds, lakes, rivers, streams, marshes, or their associated habitats. No ground-disturbing activities shall occur within the 100-foot buffer without specific approval from Western’s biologist. A biological monitor will be onsite for such approved activities.

Erosion control measures shall be placed between the outer edge of the buffer and the activity…
