Air Quality
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

The project is not located within any non-attainment areas and would not exceed any conformity requirements as dictated in the Environmental Protection Agency’s (EPA) rule “Determining Conformity of General Federal Actions to State or Federal Implementation Plans” (40 CFR 93, Subpart B). The project would not contribute to any violation of federal ambient air quality standards.

 
Close1) Prior to ground disturbance, any dry soils shall be watered to reduce fugitive dust emissions. Soils shall be monitored and continued to be watered throughout the project if dust begins to generate. Other measures that shall be implemented to minimize dust include:

• Application of asphalt, oil, water, or suitable chemicals on dirt roads, material stockpiles, and other surfaces which can give rise to airborne dust • Use of water, chemicals, venting, or other precautions to prevent particulate matter from becoming airborne in handling dusty materials to open stockpiles and mobile equipment • Maintenance of roadways in a clean condition

2) Hydrogen sulfide concentrations in the air shall be monitored at the drill site during drilling and flow testing. H2S concentrations in the produced geothermal fluid and preliminary flow will be measured during the flow test. If these measurements suggest that the H2S emissions approach 10 ppm for an 8 hour day, a chemical abatement (such as NaOH) standard for the geothermal industry will be injected into the discharge line to abate the gas. A trailer-mounted abatement skid with a storage tank for NaOH, a pump, and appropriate monitoring equipment shall be kept on site. The discharge line shall be appropriately valued to provide for abatement at any time if needed. Personnel on site during periods of possible well discharge will be trained in the use of masks and air tanks and shall wear H2S monitors at all times.
Soils
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Drilling would have limited impacts on soils. Drilling would occur in the existing paved parking lot. No topsoil would be lost. No adverse impacts are expected.

 
Close1) Topsoil shall be stockpiled and covered to minimize erosion. Topsoil shall be reapplied to the surface after completion of construction, as appropriate
Invasive, Nonnative Species
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Project activities could contribute to the spread of invasive, nonnative species within the project area through surface disturbing activities and construction and drilling vehicles.

 
Close1) Monitoring and treatment of the parking lot and access roads for invasive, non-native species shall be required for the duration of exploration. Any weeds found in the roads or parking lot would be removed completely and discarded in an appropriate manner
Wildlife Resources
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Most of the project area is located on paved or graveled surfaces. Only a small portion is vegetated and suitable for wildlife habitat (0.09 acres).

 
Close2) During construction, construction crews shall stay within the designated construction areas. All pipelines shall be capped at night to ensure that rabbits do not enter stockpiled equipment. Equipment shall be checked in the morning for rabbits or other animals. If wildlife is found in equipment they shall be allowed to leave the project area prior to moving equipment.
Noise
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Noise from drilling the deep geothermal well would have the most effect, as drilling must occur 24 hours per day. Noise impacts from drilling would be temporary. Sensitive noise receptors include the hospital, the retirement center, and the dormitory.

 
Close1) Noise screening would be used during drilling to reduce noise heard by sensitive receptors. All equipment used shall have the appropriate mufflers and noise abatement equipment necessary. A temporary noise wall shall be installed around the drilling pad. The wall shall not be greater in height than the base of the drill rig to minimize visual impacts. The wall shall be removed after drilling is complete. All neighboring properties shall be informed in writing of the proposed drilling schedule and estimated noise levels 30 days prior to commencing drilling operations. The notification shall also include the name and number of a contact person who shall receive noise complaints and respond to any local complaints about drilling or construction noise.

In the event of a complaint, the contact shall determine the cause of the noise complaint and institute reasonable measures warranted to correct the problem.

2) Power plant, pipeline, and electrical interconnect construction shall only occur between 7:00 a.m. and dusk. All neighboring properties shall be informed in writing of the proposed drilling schedule and estimated noise levels 30 days prior to commencing drilling operations. The notification shall also include the name and number of a contact person who shall receive noise complaints and respond to any local complaints about drilling or construction noise.

3) In the event of a complaint, the contact shall determine the cause of the noise complaint and institute reasonable measures warranted to correct the problem.
Public Health and Safety
"NEPA_Resource_Analysis" is not in the list of possible values (Not Present, Present, Not Affected, Present, Potentially Affected, Not Indicated) for this property.

Human Health and Safety and Risk Assessment

 
Close1) Temporary safety fencing during construction or repairs to restrict or prevent public access to active on-site construction materials or chemicals.

2) Safety signage, placed as appropriate along the construction corridor during construction or repairs, to warn of risks associated with on-site construction materials and outline measures to be taken to ensure safe use of facilities near construction areas and avoidance of construction materials.

3) Safety plan, developed by OIT prior to project commencement, will include appropriate methods (i.e. Best Management Practices) and approved combustion prevention and response practices for pentane. The plan will insure that all fire hazards (i.e. sparkinducing activities such as welding, and improperly disposed cigarettes) are kept away from the pentane storage tank.

4) The following fire prevention measures would be implemented during construction: • Fire extinguishers and shovels will be available on-site. • All brush build-up around mufflers, radiators, and other engine parts must be avoided; periodic checks must be conducted to prevent this build-up. • Smoking would only be allowed in designated smoking areas; all cigarette butts would be placed in appropriate containers and not thrown on the ground or out windows of vehicles. • Cooking, campfires, or fires of any kind would not be allowed. • Portable generators used in the Project Area would be required to have spark arresters.

5) A fire break of at least 15 feet will be constructed between the pentane storage tank and

any vegetation, landscaping or combustible materials.
