Primary Elements of a Protocol for Addressing Induced Seismicity in EGS Technologies Adapted as a Series of Parallel Activities
Extending over the Lifetime of the Operation
Initial Screening
to Determine the
Feasibility of the
EGS Project
Assess the local hazard potential from natural seismicity; the local, state, and federal regulations; the nearness of the
project to population centers; the probable magnitude of induced events; and the probable risks of potential damage
from both natural and induced events. If the proposed EGS project appears to be feasible based on this initial
screening assessment, then the
Essential Activities of the EGS project as listed below
are recommended to
proceed in the manner described within each of the ive sequential stages of project development as identiied herein.

Public and
Regulatory
Communications
Identify the local
people and
organizations to be
met with. Hold an
initial public meeting,
explain the planned
project, identify their
concerns.
Meet with and
inform the public,
regulators, and
media as to the
drilling schedule.
Upon completion
meet and explain the
drilling results.
Meet with and
inform the public,
regulators, and
media as to the
stimulation schedule
and results.
Meet with and
inform the public,
regulators, and
media as to the
operations schedule
and results.
Meet with and
inform the public,
regulators, and
media as to the
project completion.
Criteria for
Ground Vibration
and Noise
Install ground motion
and noise monitoring
instrumentations.
Report to the public,
regulators, and
media the monitoring
results.
Report to the public,
regulators, and
media the monitoring
results.
Report to the public,
regulators, and
media the monitoring
results.
Report to the public,
regulators, and
media the monitoring
results.
Seismic
Monitoring
Determine areal size
and sensitivity needed
for local array. Install
and operate the
seismic recording
array and allow
timely public access to
results.
Continue to monitor
the seismicity
recorded and
publically report the
results.
Add and/or
reposition array's
seismometers as
needed to follow
and characterize the
induced events.
Add and/or
reposition array's
seismometers as
needed to follow
and characterize the
induced events.
Continue to record
and report on the
induced seismicity
as long as needed
to describe the local
conditions.
