Hydrology and Water. Quality The proposed biomass facility is within the drainage area of the Yuba River. The project will not affect the stream bank or cause a loss of stream waters. The power plant will neither use waters from Oregon Creek for its operation, nor deposit water or wastewater into the Yuba River. The facility will utilize groundwater for operations, drinking and fire suppression. The project is subject to permits from Yuba County Public Works Department and Statewide General Permits for Storm Water Discharges Associated with Construction and Industrial Activities. Therefore, the project’s impacts on hydrology and water quality will be less than significant.
Hydrology and Water. QUALITY Would the project: Adequately Addressed by CLSP EIR, No New Impact Requires Additional Mitigation Measures Not Addressed, Less Than Significant or No Impact New or More Severe Significant Effect
Hydrology and Water. Quality The hydrology and water quality section of the EIR will evaluate the applicant's preliminary grading and drainage plans and proposed methodologies for conveying water to storm drains. Xxxxxx will perform a peer review of the preliminary Hydrology Study prepared by the applicant. The findings of the peer review and Hydrology Study will be incorporated into the EIR evaluation. We will identify and assess the potential impacts on drainage patterns and surface water quality and quantity resulting from proposed grading and other development within and near storm drains. The review and evaluation will determine whether the proposed excavation or site preparation could potentially impact groundwater resources. Xxxxxx will also analyze the potential for short‐term impacts of construction activities on surface water runoff and ensure that adequate wastewater treatment capacity is available to serve the proposed Project. If significant impacts are identified, mitigation measures will be developed to avoid or minimize Project impacts to the greatest extent feasible.
Hydrology and Water. Quality ESA will review surface hydrology and drainage issues for up to 3 sites. Current site conditions will be discussed and short-term and long-term impacts related to project implementation will be identified. Depending upon the location of the site, the impacts would be associated with drainage, stormwater, water quality, and flooding, if applicable. ESA will use existing studies conducted by the project team on the biosolids treatment processes and assess the water quality impacts from the wastewater discharge from the facility. ESA will need water quality data for the discharge from the treatment processes and the flow chart of the process units that would be employed at the facility. ESA will identify the regulatory approvals and permits that would be required for any discharges from the facility. Additional issues would include issues related to climate change such as effects of sea level rise on the project facilities (e.g. in case of a site location near a water body).
Hydrology and Water. Quality The hydrology and water quality analysis will incorporate the Summary Report Hydrogeological Evaluation (Geoconsultants, Inc. 2018) prepared for the project. This section of the EIR will describe the existing flooding, drainage, and stormwater collection systems within the immediate project area, incorporating findings of available applicant-prepared drainage analyses and stormwater management calculations. The analysis will briefly describe regulations regarding water quality, including National Pollutant Discharge Elimination System (NPDES) requirements. Potential impacts related to runoff volumes, drainage patterns, and water quality will be determined, with a qualitative discussion of impacts to water resources. Mitigation measures to contain projected stormwater flows, protect long-term water quality, and promote water conservation, will be provided as appropriate, based on recommendations from the Summary Report Hydrogeological Evaluation. This section will be closely coordinated with the Biological Resources and Utilities sections of the EIR to ensure that adequate measures are implemented to protect sensitive biotic resources that may be present or in the site vicinity and ensure that the project would be served by adequate water supplies.
