CEQA Compliance and Draft EIR Overview

CEQA Guidelines Appendix G requires that the environmental analysis presented in the Draft EIR include:

• A Summary of the proposed Project • Consequences of proposed Project• Identification of potentially significant effects • Level of potential effect• Proposed mitigation measures • Alternatives to the proposed Project• Other considerations

CEQA ComplianceCEQA requires that prior to project approval, the Lead Agency must consider the potential effects of the proposed project and identify: • Any significant potential impacts of the proposed

Project on the environment, and indicate the manner in which those significant impacts can be avoided or mitigated;

• Any unavoidable adverse impacts that cannot be mitigated; and

• Any reasonable and feasible alternatives to the proposed project that would eliminate any significant adverse environmental impacts or reduce the impacts to a less-than-significant level.

The project objectives include:• Provide reliable treated water service for the City

of Lincoln within NID’s service area;• Provide reliable treated water service to areas

outside of the City but within NID’s service area; and

• Provide additional raw water supplies to existing and new customers.

Project Objectives

• The proposed Project will address projected demand for treated water within western portions of Placer County located within the NID boundary.

• The proposed Project entails conveying raw water from Combie Reservoir, storing the raw water in an intermediate storage reservoir, treating the water to potable standards, and conveying treated water to customers for municipal and commercial uses.

• The proposed Project includes the construction of approximately 16 miles of raw and treated water pipelines, canal improvements, a raw water storage reservoir, a 40 million gallon per day (MGD) water treatment plant including treated water storage, a treated water hydraulic control and metering station, and hydroelectric facilities.

• The DEIR is a Project and Program-level EIR (Hydroelectric).

Greenhouse Gas EmissionsBrief Synopsis*

• GHG-1: Generate greenhouse gas emissions and have significant impact on the environment?• GHG-2: Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gasses?

• According to the Placer County Air Pollution Control District (PCAPCD) CEQA Air Quality Handbook, the PCAPCD has not established a Threshold of Significance for construction of operational related GHG emissions.

• The PCAPCD recommends alternative thresholds that have been adopted or recommended by other lead agencies or air Districts.

• Therefore, significance thresholds recommended by the Sacramento Metro Air Quality Management District (SMAQMD) were used to assess the potential impacts from project-specific GHG emissions.

• The CalEEMod was run for buildout and results indicate that project construction and operation emission were below the SMAQMD thresholds.

Chapter 4: Project Alternatives

• CEQA requires that the Lead Agency consider a “reasonable range” of alternatives that meet the basic objectives of the proposed Project, while also addressing any potentially significant impacts that might result from approval of the proposed project.

• In addition, CEQA requires consideration of the “No Action” alternative, which means that no action would be taken to approve the proposed project or other proposed alternatives.

• No Action Alternative• PCWA Ophir Alternative• Bear River Pump Station Alternative*• Auburn Ravine Water Treatment Plant

Alternative*• Alternatives within the Project

• Southern Pipeline Corridor Alternative• Magonigal RWTP Site Alternative*• Whisky Run Reservoir Site Alternative*

Project Alternatives

* Indicates alternative did not meet requirements and was rejected from further consideration

Project Alternatives

• CEQA Guidelines Section 15126(e)(2) requires an EIR to identify an “environmentally superior alternative.”

• The PCWA Ophir Alternative would have similar impacts to the proposed Project and would not meet all of the project objectives. The pipeline corridor would travel through more urbanized areas, and would result in more potential conflicts, including creek crossings.

• The Phase 2 Southern Pipeline Corridor Alternative has an increased potential for significant adverse environmental effects compared to the proposed Project.

• The No Action Alternative does not meet objectives.

• As a result, the proposed Project is considered the Environmentally Superior Alternative.

• Refer to Tables 4.4-1 through 4.4-3 for summary details.

Environmentally Superior Alternative

Chapter 5Other CEQA Considerations

5.1 Growth Inducing Impacts Similar to population and housing discussion

5.2 Significant and Unavoidable Impacts“After implementation of the recommended mitigation measures, all of the potentially significant impacts associated with the proposed project would be reduced to a less than significant level.”

5.3 Significant Irreversible Environmental Changes (non-renewables)The proposed Project would not result in a large commitment of additional water resources; therefore, no significant irreversible environmental changes were identified.

Chapter 5Other CEQA Considerations

5.4 Mandatory Findings of Significance• “Finding No. 1: The proposed project would not have the potential to

significantly affect biological or cultural resources.”

• “Finding No. 2: The proposed project would not have cumulatively considerable impacts.”

• “Finding No. 3: The proposed project would not cause substantial adverse effects on human beings.”

5.5 Energy ConservationConstruction fuel consumption not estimated to be any more inefficient, wasteful, or unnecessary than at other construction sites in the region. Operation – Transportation and Facilities Demands Assessed• Gravity Flow, pressure reduction station conversions to

electrical energy, shade trees around operations buildings.

Other CEQA Considerations5.6 Cumulative Impacts (Past, Present, Reasonably Anticipated Future Projects)

• An EIR must discuss the cumulative impacts of a project when the project’s incremental effect is “cumulatively considerable,”meaning that the project’s incremental effects are considerable when viewed in connection with the effects of past, current, and probable future projects.

• Assessment included Transportation, Housing and Development, Water and Wastewater, Conservation and Restoration (Refer to Table 5.6-2). Included projects such as Midwestern Placer Regional Sewer Project, NID Parker (Centennial) Reservoir, NID Rollins Capacity Projects, NID Orr Creek Reservoir Capacity Restoration, among many others.

• No potential impacts associated with the proposed project were found to be cumulatively considerable and no mitigation measures were required.
