Jersey Valley Geothermal Development Project
Environmental Assessment: NV063 -EAO8-09 1
Mitigation Measures
The unit operator shall monitor and collect representative temperature; flow, stage or
equivalent; and basic thermal water chemistry from each of the two springs known as the
Jersey Valley Hot Springs, which are located in the SW1/4, SW¼ of Section 28 and the SE¼,
SE% of Section 29, respectively.
The unit operator shall monitor and collect representative temperature; flow, stage or
equivalent; and basic thermal water chemistry from these hot springs on the following
schedule, unless otherwise modified by the BLM authorized officer:
• Once immediately prior to the commencement of drilling, and once immediately
following the completion of drilling, of each new or redrilled geothermal well in the
geothermal unit area;
• Each year until one year before the commencement of geothermal fluid production
and injection operations from the geothermal unit area for the utilization facility;
• Once each quarter from one year before the commencement of geothermal fluid
production and injection operations from the geothermal unit area for the
utilization facility until the cessation of all geothermal fluid production and injection
operations from the geothermal unit area for the utilization facility; and
• Once each year from the cessation of all geothermal fluid production and injection
operations from the geothermal unit area for the utilization facility until all
geothermal wells within the geothermal unit area have been abandoned.
Collected data shall be reported to the BLM in written form by the unit operator within
30 days of its receipt. The unit operator shall also submit an annual report to the BLM
within 30 days of the end of each calendar year summarizing and interpreting the
monitoring data collected during the preceding calendar year.
If the BLM authorized officer determines that the available monitoring information
indicates the need for further monitoring information to determine if unit operations are
creating adverse impacts to the hot springs, then the BLM authorized officer may require
that the unit operator conduct additional monitoring of the hot springs, including:
• Collection of monitoring data at increased monitoring frequencies;
• Collection of additional monitoring parameters from current monitoring locations;
and/or
• Collection of monitoring data from additional monitoring locations.
Should this monitoring program demonstrate that adverse impacts to the hot springs may
be occurring, the unit operator shall, as required by the BLM authorized officer,
immediately retain a qualified third-party consultant, acceptable to the BLM authorized
officer, to review the collected data and to evaluate the collected data and recommend
reasonable mitigation measures. A group consisting of the applicable stakeholders,
