S-2 Summary v25
The Park, consisting of approximately 856 acres, is located at 10791 East Empire Street in Grass Valley, Nevada County, California. East Empire Street traverses the Park in an east-west direction. North of Empire Street, State Route 174 (SR 174) traverses the Park from northwest to southeast and then extends along the eastern boundary of the Park and the Union Hill area. Land uses surrounding the Park include limited commercial, industrial, open space and residential. PROJECT OVERVIEW In 2006, California Department of Toxic Substance Control (DTSC) and the Central Valley Regional Water Quality Control Board (RWQCB) entered into a Joint Cleanup and Abatement Order, Imminent and/or Substantial Endangerment Determination and Partial Consent Order (Joint Order) with the Department of Parks and Recreation (DPR) and Newmont USA Limited (Newmont) to oversee characterization, evaluation, and remediation at Empire Mine State Historic Park (Park). DPR is the present owner of the Park. Newmont is a successor in interest to a former owner and operator of some of the mines located at the Park, including the Empire Mine. New Verde Mines LLC, a subsidiary of Newmont, still retains certain mineral rights underlying the Park. Newmont and DPR (together, the Project Proponents) will be working together throughout the Site Characterization and Remediation Project (Project) term to address the remediation of potentially hazardous substances at the Park. This Draft Program Environmental Impact Report (Draft PEIR) has been prepared for the DPR to evaluate the potential environmental effects of the Project at the Park located in Nevada County, California. DPR is a state agency and will be the lead agency under the California Environmental Quality Act (CEQA), Public Resources Code (PRC) §21000 et seq., and CEQA Guidelines, California Code of Regulations (14 CCR) §15000 et seq. This document has been prepared in accordance with CEQA Guidelines to evaluate the Project’s potential environmental impacts. The Project Proponents and their respective contractors continue to conduct characterization and evaluation studies to determine the nature and extent of constituents of concern (COC) that exist at the Park, and to assess how potential exposure pathways could be reduced or eliminated. This approach facilitates the development of short-term interim actions and permanent remediation measures. A three tiered approach is used for each Remediation Area: (1) Characterization and Evaluation; (2) Interim Actions; and (3) Remediation. Characterization work determines the nature and extent of COC exceeding the Department of Toxic Substance Control (DTSC) and the Regional Water Quality Control Board (RWQCB) standards and/or guidelines. Evaluation work determines the extent to which the identified constituents need to be addressed through implementation of interim actions and/or by the suite of potential remediation measures.

Site Characterization and Remediation Draft Program EIR Empire Mine State Historic Park California Department of Parks & Recreation August 2009
S-3 Summary v25
Interim actions eliminate or reduce the potential exposure of COC to humans and the environment while permanent remediation options are evaluated and then implemented. Examples of interim actions include, but are not limited to, exclusionary fencing, and implementation of Best Management Practices (BMPs) to ensure that the COC remain isolated from potential exposure pathways. The purpose of remediation is to permanently eliminate or reduce the risk of potential exposure pathways to humans or the environment from COC identified at the Park. To the extent applicable to a Remediation Area, proposed remedial actions would include appropriate signage and could include (but are not limited to) one or a combination of the following:
• In-situ covers, establishment and stabilization. This action would involve establishing a cover (either a vegetative cover or placement of rock or aggregate) in areas exceeding cleanup goals and/or water quality objectives. The remediation area would be graded or contoured to provide a stable landform, establish controlled drainage patterns, and to prepare the surface materials for establishment of a seed bed, as applicable. In addition to possible grading activities, surface materials could be ripped with track dozer equipment or disked and harrowed using conventional agricultural equipment. The surface materials would be assessed to determine any nutrient, substrate, or geochemical amendment requirements that could be necessary for establishing a stable vegetated landform that would protect against water and wind erosion. Amendment application and seeding activities would likely be conducted using conventional broadcast type equipment such as hydroseeders, herd or cyclone seeders, or using conventional drill type agricultural equipment. Vegetative communities would consist of interim sterile or native plant species, as appropriate. Stormwater BMPs would be implemented to protect the revegetated surface(s). In addition, this action could involve the use of retaining walls, cribbing, gabions and/or hill picker baskets to stabilize sloped or over-cut materials.
• Selective removal and/or replacement of surface materials. This action would involve removing some amount of surface material, including sediments from watercourses, in areas exceeding cleanup goals and/or water quality objectives. Depending on site-specific circumstances, soil could be replaced with either on-site material or with clean import material to an elevation consistent with surrounding topography and revegetated with interim and/or long-term native plant species, as appropriate. Depending on the site and proposed activities, grading or contouring of the soils or adjacent surface materials could be required to provide surface stability. Revegetation could include similar activities as described in the In-situ cover remediation option. Remediation actions could include placement of rock or aggregate on the surface instead of revegetation. Installation of retaining walls, cribbing, gabions and/or retaining walls could be included.

Site Characterization and Remediation Draft Program EIR Empire Mine State Historic Park California Department of Parks & Recreation August 2009
S-4 Summary v25
• Complete removal and/or replacement of surface materials. This action would involve complete removal of all surface materials (mine and mill materials, and organic soils) exceeding cleanup goals and/or water quality objectives. The removed material would be managed on-site or at an appropriate off-site facility, depending on the material and its COC characteristics. Grading or contouring of the area could be required and revegetation could include similar activities as described in the In-situ cover remediation option (See above). Stormwater BMPs would be implemented to protect the Remediation Area. Remediation actions could include placement of rock or aggregate on the surface, instead of revegetation. In addition, this action could involve the use of cribbing, gabions, or retaining walls to stabilize sloped or over-cut materials.
• Placement of removed soils or materials within the Park. If characterization and evaluation determines that a material qualifies as either a Group B or Group C waste, and the RWQCB and the DTSC concur, DPR can manage the materials at the Park provided that the Project Proponents comply with the Materials Management Plan and the Site Health and Safety Plan. Management of materials at the Park will meet the specific applicable requirements of California Regional Water Quality Control Board (RWQCB) and Department of Toxics Substance Control (DTSC). Management of materials at the Park could include construction and/or closure of on-site Mining Units, as defined in Section 2.3.3.1, Department of Toxics Substance Control and Regional Water Quality Control Board, above.
• Placement of cover over selected areas. This action would involve covering selected areas consisting of mine and mill materials with the placement of rock or aggregate material, a clean fill cover, or an engineered low permeability cover containing an infiltration barrier. Installation activities could require grading or contouring of the area with either tracked or rubber-tired dozer equipment or tracked excavation equipment and rubber-tired hauling equipment. The clean fill cover could be stabilized by revegetating with interim and/or long-term native plant species, as appropriate. Stormwater BMPs would be implemented to protect the Remediation Area. In addition, this action could involve the use of cribbing, gabions, or retaining walls to stabilize sloped or over-cut materials.
• Maintenance and enhancement of existing cover. This action would involve maintaining and enhancing existing vegetative cover and/or duff (organic matter in various stages of decomposition on the floor of the forest) in areas where characterization, evaluation or implementation of institutional and/or engineered control sufficiently limits exposure to COC and associated unacceptable health risk.
• Use of engineered controls to prevent access. This action would involve the installation of exclusionary fences and/or boardwalks to control unauthorized access to certain areas potentially containing COC. In conjunction with use of other engineered controls, appropriate viewing areas (including overlooks) would be installed, as necessary. This action could also be utilized as an interim action.

S-5 Summary v25
• Use of Institutional controls. This action would include using non-physical administrative or legal controls to limit the human exposure to COC. Examples of this could include but are not limited to: Use Restrictions and Covenants and Superintendent Orders (an authoritative mandate, command, or direction issued by a senior administrator, or Superintendent, under the authority of California State Parks).
• Stormwater collection and diversion structures. This action would include the engineering and construction of stormwater collection and diversion structures to minimize or eliminate stormwater contact with source materials or to divert and collect stormwater that has contacted source materials. Engineered collection and diversion structures would be designed to manage specified duration and flow conditions and would generally be constructed of clean imported rip-rap (e.g., cobble or larger size rock) materials, geotextile materials, imported clean soil materials, cement grout, concrete, conventional culvert-type installations. Additional stormwater diversion facilities could include but not be limited to engineered creek and/or water diversions (e.g., use of pumping devices), or construction of structures (e.g., roofs) that prevent direct precipitation on Remediation Areas. Stormwater BMPs would be implemented to control erosion and sedimentation, as applicable.
• Implement active treatment measures. This action would include measures such as construction of an active water treatment facility that would use chemical reagents or mechanical treatment processes to convey, oxidize and precipitate targeted metals from water within the facility and then discharge the treated water downstream of the facility in compliance with cleanup goals and/or water quality objectives.
• Implement passive treatment measures. This action would include measures such as construction or enhancement of a natural or constructed wetland, swale, or other passive water treatment systems that utilize passive oxidation and reduction reactions, soils attenuation, and/or wetland vegetation to remove targeted constituents from water and then discharge the treated water downstream in compliance with cleanup goals and/or water quality objectives.
• Other water management measures. This action would include measures such as pumping water from the Empire Mine irrigation wells to reduce effluent water quantities requiring treatment or management and installation of zeolite cells to remove zinc from surface water runoff from the mine yard to reduce metals concentrations and/or moderate the discharge rate of the mine effluent that could be treated at the treatment facility.
• Remediation of structures. This action would involve the replacement or coating of metal roofing, and cleaning of structure interiors to ensure that applicable cleanup goals are achieved.

NEEDS AND OBJECTIVES DPR’s mission is to provide for the health, inspiration, and education of the people of California by helping to preserve the state’s extraordinary biological diversity, protecting its most valued natural and cultural resources, and creating opportunities for high-quality recreation. The fundamental goal of a historic park, like Empire Mine, is the preservation of resources of historic and prehistoric value. The interpretation and presentation of these resources should help the visitor appreciate, understand, and enjoy learning about the aspect of California’s heritage for which the Park was established. The use and management of resources at the Park will emphasize the historic and natural values subordinating the recreational potential where historic integrity may be violated. The intent of the Project is to:
• Provide for the inspiration and education of the people of California by helping to preserve the state’s extraordinary biological diversity and creating opportunities for high-quality outdoor recreation;
• Protect and preserve valuable natural and cultural resources within the Park; • Protect public health and the environment through minimizing exposure of Park
users and DPR personnel to unacceptable health risks; and • Comply with the intent and terms of the DTSC and RWQCB Joint Order.
The DTSC seeks to provide the highest level of safety, and to protect public health and the environment from toxic harm. DTSC issued an Order to Post to DPR for portions of the Park on July 27, 1989, based on elevated concentrations of lead, arsenic, and mercury in soils or other materials sampled in the vicinity of the Cyanide Plant and the Sand Dam. The RWQCB regulates discharges to surface water at the Park including both stormwater and point source water releases. In the non-stormwater context, on June 23, 2006, the RWQCB issued DPR Waste Discharge Requirements (Order No. R5-2006-0058) and an NPDES (No. CA0085171) to regulate the discharge from the Magenta Drain. The Joint Order initially identified four (4) Priority Action Work Plans for characterization and investigation: Exclusions, Trails, Red Dirt Pile, and Residences as well as requiring a Magenta Drain Sampling and Monitoring Program. DTSC amended the Joint Order in July of 2007 to include additional Work Plans, Activities, and Monitoring Programs with anticipated schedules.

Issues Evaluated The scope of issues evaluated in this Draft PEIR was determined through: an NOP, distributed to the OPH/SCH, responsible agencies, interested groups and individuals, and surrounding property owners. Issues raised for evaluation include the topics of aesthetics, air quality, biological resources, cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, land use and planning, noise, public services, and transportation. EIR SUMMARY As required by CEQA, this Draft PEIR focuses on expected significant or potentially significant environmental effects (14 CCR § 15143). The NOP identified environmental resources that could be potentially affected. The Draft PEIR evaluates each potential impact to the environmental resources, identifies significance relative to established standards, and determines appropriate mitigation, as necessary, to avoid impacts or reduce them to less than significant levels. This document includes detailed evaluations for those environmental issues identified for study. Effects Found Not to be Significant The following resource categories were found to have no potential for adverse impact or the potential for environmental impact was less than significant with no Project Requirements:
• Land Use, Agriculture, and Minerals (Section 4.8); and
• Public Services and Recreation (Section 4.10). Effects Found to be Less Than Significant
Some of the impacts analyzed in this Draft PEIR are considered to be less than significant and require no mitigation. Other impacts, (i.e., those that are considered to be potentially significant) can be reduced to a less than significant level with the implementation of Project Requirements and proposed mitigation measures. All of the impacts analyzed in this Draft PEIR, including those considered to be less than significant, are summarized in Table S-1, Summary of Project Requirements, Mitigation Measures and Significance Determinations for Each Identified Impact Statement.

Summary v25
Impacts Found to be Potentially Significant and Unavoidable After applying CEQA standards of significance to the entire range of impacts that would result from implementation of the Project, 14 significant and unavoidable impacts have been identified. DPR has designed the proposed Project with both Standard and Specific Project Requirements and has added or incorporated mitigation measures to reduce potentially significant impacts to the extent feasible. The Project would, however, have potentially significant and unavoidable impacts for the resource categories provided below.
• Biology. Program Actions at the Park could require activities that would have a significant adverse effect in riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the CDFG or the USFWS (Section 4.3; Impact Statement 4.3-2; Impact Statement 4.3-6). Implementation of Program Actions could substantially degrade the sensitive natural communities located within the Park: the Arroyo Willow Forest and Woodland Alliance and the Westside Ponderosa Pine Association.
• Biology. Program Actions at the Park could have a significant adverse effect on federally protected waters of the U.S., as defined by CWA §404, through direct removal, filling, hydrological interruption, or other means (Section 4.3; Impact Statement 4.3-3; Impact Statement 4.3-7). Program Actions could have a substantial adverse effect on the 29.63 acres of Wetland of the U.S. located in the Core Area of the Park, and the 19.3 acres of USACE jurisdictional wetlands through direct removal, filling, hydrological interruption, or other means.
• Biology. Program Actions at area-specific locations could have a significant adverse effect, either directly or through habitat modification, on sensitive Bat species (Section 4.3; Impact Statement 4.3-5(D)). Implementation of Program Actions at area-specific locations could adversely impact the seven special-status bat species potentially present at the Park through the removal or modification of buildings, large trees and snags, and mine shafts where bats commonly roost.
• Biology. Program Actions at the Park could have a significant adverse effect, either directly or through habitat modification, on nesting raptors and migratory birds (Section 4.3; Impact Statement 4.3-1(E); Impact Statement 4.3-5(E)). Program Actions resulting in the disturbance of vegetation and/or structures could result in the take of nesting raptors and migratory birds. Furthermore, removal of vegetation including trees could result in alteration of habitat for nesting raptors or migratory birds.
• Cultural Resources. Program Actions could cause a significant adverse change in the significance of a historic resources pursuant to CCR §15064.5 (Section 4.4; Impact Statement 4.4-1; Impact Statement 4.4.-4). Two of the four Program Actions associated with the Project (interim actions, and remediation options) have the potential to cause a substantial adverse change in the significance of a

historic resource. The potential for an impact is dependent on the location of remediation activities within the Park. At the Program level, it is not feasible to determine if specific impacts to historic resources can be reduced to a less than significant level given the lack of specific information concerning the exact location and nature of program activities.
• Cultural Resources. Program Actions could cause a significant adverse change in the significance of an Archaeological Resource pursuant to CCR §15064.5 (Section 4.4; Impact Statement 4.4-2) Program Actions such as interim actions, and remediation activities have the potential to significantly impact previously undocumented sites by causing damage, destruction, or removal of physical components.
• Noise. Program Actions could result in exposure of persons to, or generation of, noise levels in excess of standards established in Local General Plan, Noise Ordinance, or applicable standards of other agencies (Section 4.9; Impact Statement 4.9-1). Implementation of Program Actions could result in noise levels exceeding applicable local standards through the use of construction equipment at the Park and off-site truck trips (e.g. importation or exportation of materials) increasing noise levels along roads utilized for implementation of the Project.
• Noise. Program Actions could result in a significant permanent increase in Ambient Noise levels in the Park vicinity (Section 4.9; Impact Statement 4.9-2). Implementation of Program Actions could result in noise levels that permanently exceed applicable local standards through the use of construction equipment at the Park and off-site truck trips (e.g. importation or exportation of materials) increasing noise levels along roads utilized for implementation of the Project.
• Noise. Program Actions could result in significant temporary or periodic increase in Ambient Noise levels in the Park vicinity (Section 4.9; Impact Statement 4.9-3); Implementation of Program Actions could result in noise levels that temporarily exceed applicable local standards through the use of construction equipment at the Park and off-site truck trips (e.g. importation or exportation of materials) increasing noise levels along roads utilized for implementation of the Project.
• Cumulative Cultural Resources. Program Actions could result in cumulatively considerable impacts to cultural resources (Section 5.0; Section 5.2.4); and
• Cumulative Noise. Program Actions could result in cumulatively considerable impacts to noise receptors because of exceedance of local noise standards or significant increase in ambient noise levels (Section 5.0; Section 5.2.4).
Summary of Alternatives CEQA Guidelines Section 15126.6(a) requires that a Draft EIR evaluate a range of reasonable alternatives to the proposed project that would feasibly attain most of the basic project objectives but would avoid or substantially reduce any of the significant effects of the proposed project.

Based upon DPR’s Project objectives, the identified significant impacts (both before and after the application of mitigation), and CEQA requirements and guidelines for consideration of alternatives, the following potential alternatives are considered:
1. Alternative 1: No Project – existing conditions at Park would remain unchanged. 2. Alternative 2: Less Intensive Program Actions Alternative – implementation of
less intensive Program and Project Actions to reduce Project-related impacts.
