CONDITIONS OF APPROVAL FOR GEOTHERMAL UTILIZATION
between all participating entities. All NRHP-eligible and unevaluated cultural sites that were
identified during the cultural resources inventory would be avoided.
• WILDLIFE (INCLUDING THREATENED AND ENDANGERED SPECIES,
SPECIAL STATUS SPECIES AND MIGRATORY BIRDS)
Mitigation Measure:
Initial ground disturbing activities would not be conducted during the migratory bird nesting
season (April 1-August 15) unless necessary, and then only after inventories for migratory
birds and nests were conducted by a qualified biologist acceptable to the BLM. This survey
would be conducted to identify either breeding adult birds or nest sites within the specific
areas to be disturbed. If active nests are present within the areas to be disturbed, Ormat would
coordinate with the BLM or appropriate state officials, as applicable, to develop appropriate
protection measures for the active nest sites, which may include avoidance, construction
constraints, and/or the establishment of buffers. Following the implementation of this
mitigation measure, the potential impacts to migratory birds should be reduced.
• INVASIVE, NONNATIVE SPECIES:
Ormat has committed to follow the mitigation measures (see Section 2.1.11), “To prevent the
spread of invasive, nonnative species, vehicles and equipment would be power washed,
including body and undercarriage, prior to entering public lands managed by the BLM” and
geothermal resources special lease stipulations.
• VEGETATION:
Mitigation Measures:
Seeding of disturbed areas associated with soil association 211 would be completed using the
following BLM-approved native seed mixture and application rate:
Common Name Scientific Name Pounds/acre (bulk)
Indian Ricegrass Oryzopsis hymenoides 3.40
Bottlebrush Squirreltail Elymus elymoides 1.70
Needle and Thread Stipa Comata 3.78
Scarlet Globemallow Sphaeralcea coccinea 0.78
Seeding of disturbed areas associated with soil associations 662, 673, 2711, 2721, 2555,
251, 652 and 1340 would be completed using the following BLM-approved native seed
mixture and application rate:
Common Name Scientific Name Pounds/acre
Basin Wildrye Leymus cinereus 4.65
Indian Ricegrass Oryzopsis hymenoides 1.70
