Jersey Valley Geothermal Development Project<br />
<strong>Environmental</strong> Assessment: NV063-EAO8-091<br />
The only recorded fire within the Jersey Valley Unit Area <strong>and</strong> proposed transmission line<br />
corridor was the Gooseberry Fire which burned within the very southwest corner <strong>of</strong> the Jersey<br />
Valley Unit Area in 2001.<br />
3.8.2 <strong>Environmental</strong> Consequences<br />
3.8.2.1 Proposed Action<br />
Surface disturbance associated with the proposed Project activities within the Jersey Valley Unit<br />
Area <strong>and</strong> transmission line corridor would result in the loss <strong>of</strong> vegetation.<br />
Approximately 86.67 acres <strong>of</strong> the proposed disturbance within the Jersey Valley Unit Area <strong>and</strong><br />
transmission line corridor is “temporary” (see Table 5) <strong>and</strong> vegetation can be allowed to recover<br />
after construction is completed.<br />
Approximately 80.66 acres <strong>of</strong> proposed disturbance within the Jersey Valley Unit Area <strong>and</strong><br />
transmission line corridor is “permanent” (see Table 5) <strong>and</strong> would be “lost” over the life <strong>of</strong> the<br />
proposed Project, but would be recovered without residual impact after site reclamation<br />
commences.<br />
Disturbed areas could have an increase in cheatgrass compared to non-disturbed areas (see<br />
Section 3.6).<br />
As part <strong>of</strong> the Project, disturbed areas would be reclaimed in accordance with applicable BLM<br />
requirements. The following mitigation measure is recommended to seed disturbed areas with<br />
seed mixtures <strong>and</strong> minimize the spread <strong>of</strong> invasive, normative species.<br />
Mitigation Measures:<br />
Seeding <strong>of</strong> disturbed areas associated with soil association 211 would be completed using<br />
the following BLM-approved native seed mixture <strong>and</strong> application rate:<br />
Common Name Scientific Name Pounds/acre (bulk)<br />
Indian Ricegrass Oryzopsis hymenoides 3.40<br />
Bottlebrush Squirreltail Elvrnus elvrnoides 1.70<br />
Needle <strong>and</strong> Thread Stipa Comata 3.78<br />
Scarlet Globemallow Sphaeralcea coccinea 0.78<br />
Seeding <strong>of</strong> disturbed areas associated with soil associations 662, 673, 2711, 2721, 2555, 251,<br />
652 <strong>and</strong> 1340 would be completed using the following BLM-approved native seed mixture<br />
<strong>and</strong> application rate:<br />
