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

(1) MIGRATORY BIRDS AND RAPTORS:

(a) 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 shall be avoided during the nesting season (March 1 to August 15). If construction activities occur during the nesting season, Western will survey the construction area for migratory bird nests prior to construction 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 on site for construction activities within the buffers. If the biological monitor determines that activities are likely to cause nest impacts or nest abandonment, then construction activities in the area shall be postponed until nestlings have fledged or the nest is no longer active.

(2) BURROWING OWL

(a) From February 1 to August 31 activity will be prohibited within 250 feet of potential burrowing owl nesting dens. From September 1 through January 31, disturbance will be prohibited within 160 feet of potential burrowing owl dens.

Or a qualified biologist will conduct nesting and wintering surveys. If nesting or wintering activity is detected, a qualified biologist will mark and monitor an appropriate non-disturbance buffer in the vicinity of burrows that have been active within the last three years. Within the buffer zone, all activities will be prohibited from February 1 to August 31.

(3) VALLEY ELDERBERRY LONGHORN BEETLE (VELB)

(a) If any activities occur outside the Folsom substation fence, prior to project activities, a qualified biologist will flag elderberry shrubs within 100 feet of the project activities. A minimum buffer zone of 20 feet outside of the dripline of each elderberry plant will be provided during all activities.

(4) SEASONAL WETLAND HABITAT (INCLUDING VERNAL POOLS): Although construction activities will be inside the substation, there are sensitive wetland habitats south and southeast of the Elverta Substation where the transformer shell will be placed. The Contractor will adhere to the following measures:

(a) Vehicle access will only be permitted on well-established roads unless soils are dry. Soils will be considered sufficiently dry for vehicle access when they resist compaction, and after annual plants have set seed (generally June 1 to September 30, or as determined by a qualified biologist based on personal observation of the soils).

(b) When feasible, all maintenance activities will be routed around wet areas while ensuring that the route does not cross sensitive resource areas.

(c) If activities are proposed within 250 feet of a seasonal wetland a biological monitor will be present and/or a qualified biologist will clearly mark the limits of the feature(s) or appropriate buffers.

Message from the Administrator

At Western, we show our commitment to safety every day through the actions we take, the training we offer and the work conditions we provide. We expect the same commitment to safety from each of our contractors who provide products or services to Western. In performing work for Western, all contractors must make the right decisions to ensure that the work environment is as safe as possible.

Our safety program is based on four points:

Safety procedures or common sense must be applied by each Federal and contract employee. Safety should not be set aside to meet a project schedule or for personal convenience.

Employees and contractors must believe that they have the right and the responsibility to identify and take action to reduce, if not eliminate, hazardous work environments and hazardous work practices.

Managers and supervisors must lead by example and execute their responsibility to ensure each job is accomplished in a safe and healthy way.

Safety is a personal responsibility. Each individual makes the decision on what action to take to accomplish a task.

By integrating these principles into every task we take, together we can ensure Western is a safe place to work.

Mark A. Gabriel Administrator
