Pentz Pit Mine Reclamation Plan v January 2021

1.0 INTRODUCTION

This Revised Reclamation Plan (“Plan”) has been prepared in support of ongoing and vested surface mining and reclamation activities at the NorCal Sand and Rock, Inc. (“NorCal”) Pentz Pit Mine in Butte County, California. NorCal operates the Mine, a ±228‐acre facility that produces sand and gravel and aggregate products, located at 4970 Slickens Road in unincorporated Butte County (see Figure 1, Site Vicinity Map). NorCal operates pursuant to a lease with Baldwin Contracting, Inc., doing business as Knife River Construction (“KRC”). NorCal and its predecessors‐in‐interest including BCJ and Baldwin have been continuously mining at the site since at least 1970. In addition to mining and reclamation, existing permitted and accessory uses at the site include aggregate processing, stockpiling, load‐out, sales, equipment storage and maintenance (see Figure 2, Existing Facilities). Surface mining and reclamation operations at the site are conducted pursuant to vested mining rights and Butte County Reclamation Plan No. RP 78‐99 (“RP 78‐99”) approved on June 7, 1978.

This Plan serves to clarify the reclamation mapping boundaries and contours to cover existing and planned reclamation activities and achieve current surface mining reclamation standards. NorCal’s operations continue to reclaim the site by removing the non‐native Cherokee hydraulic mine tailings that have washed down and filled portions of Sawmill Creek Ravine (“Ravine”). In doing so, NorCal plans to restore the property to a more natural, native terrain over time. The planned post‐mining end use is gently rolling foothills, which is consistent with the original condition of the site and the end use approved under RP 78‐99.

1.1 Plan Organization

Section 2.0 of this Plan provides an overview of reclamation activities and is generally organized around California Surface Mining and Reclamation Act (“SMARA”) requirements, beginning with SMARA’s key statutory requirements. Section 3.0 of this Plan addresses specific Butte County (lead agency) requirements, where those requirements supplement or amplify the requirements covered in Section 2.0.

This Plan has been prepared pursuant to the following requirements associated with the reclamation of mined lands:

 California Surface Mining and Reclamation Act of 1975, as amended (Public Resource Code §2710 et seq.);  State Mining and Geology Board SMARA implementing regulations (California Code of Regulations, Title 14, §3500 et seq.);  Butte County General Plan; and  Butte County Code (“BCC”), Chapter 13, Article II, Surface Mining and Reclamation (“SMR Code”).

Pentz Pit Mine Reclamation Plan 1 January 2021

Many statutory and regulatory sections of SMARA are either presented verbatim or paraphrased throughout to facilitate a better understanding of Plan contents and requirements. Requirements found in Article 1 (14 CCR §3500 et seq.) and Article 9 (14 CCR §3700 et seq.) of SMARA’s implementing regulations are addressed under combined resource headings where possible, to minimize duplication of Plan contents. SMARA citations and standards that follow section headings in italics have been abbreviated.

1.2 Site History and Current Operating Entitlements

NorCal and its predecessors, including BCJ and KRC, have been continuously mining for sand and gravel and producing aggregate products at the Mine since 1970 or earlier. In recent years until 2018, BCJ was operating the Mine, including in areas that were not explicitly covered by RP 78‐ 99. In 2018, NorCal assumed the position of lessee for purposes of operating and reclaiming the Mine. NorCal’s operations continue to reclaim the site by removing the non‐native Cherokee hydraulic mine tailings that have washed down and filled the Ravine. In doing so, NorCal plans to restore the property to a more natural, native terrain over time.

1.3 Vested Rights

SMARA exempts a vested rights holder from the need to acquire a permit to mine from the local permitting agency as long as such vested rights continue and as long as no substantial changes are made in the mining operation (Cal. Pub. Resources Code § 2776(a)). Under SMARA, a person is deemed to have a vested right if, “prior to January 1, 1976, the person has, in good faith and in reliance upon a permit or other authorization, if the permit or other authorization was required, diligently commenced surface mining operations and incurred substantial liabilities for work and materials necessary for the surface mining operations.” (Id.) The SMR Code, enacted in 1993, similarly provides that any surface mining operation authorized to operate under a permit issued prior to January 1, 1976, is exempt from the requirement to obtain a surface mining permit (SMR Code §13‐113).

As stated in Section 1.2 above, the Mine has been continuously mined since 1970 or earlier, long before the effective dates of SMARA (1976) and the SMR Code (1993). Butte County has recognized the vested rights at the Mine since at least as far back as 1978.

1.4 Purpose for Revised Reclamation Plan [CCR §3502(a)]

In October 2018, the County performed an annual surface mine inspection and found that, overall, operations have been performed in a manner that is consistent with the original RP 78‐ 99 and would not preclude the site from reclamation. However, the County noted that excavations appear to have extended beyond the approved boundaries of RP 78‐99, and requested that the operator work to update its reclamation plan boundary.

Whether the County’s statement is accurate is uncertain; however, the Operator agrees that the reclamation plan should be updated to include measures consistent with RP 78‐99 that result in reclamation of all mine tailings.

Pentz Pit Mine Reclamation Plan 2 January 2021

In response, NorCal submitted application to the County for processing of this Plan as a minor modification to the existing RP 78‐99 pursuant to BCC Section 13‐118 (Minor Modification). This Plan has been developed to provide an environmentally superior update to the original RP 78‐99 and to accomplish the following objectives:

1. Update the original RP 78‐99 reclamation plan mapping to clearly delineate existing Mine boundaries. 2. Encompass within the Mine boundary all existing disturbances that were not originally explicitly denoted in RP 78‐99, without expanding those disturbances any further into areas that were not already covered by RP 78‐99. This includes the areas south of the existing processing plant site (disturbed by others) as well as a “gap area” east of the plant where reclamation will continue to occur. The original RP 78‐99 already provides for mining upstream of the existing “gap area.” 3. Apply the current reclamation standards, as set forth in SMARA CCR §3700 et seq., to all additional portions of the reclamation boundary. 4. Identify the locations of existing temporary stream crossings in the Ravine. 5. Lay the necessary ground work for obtaining subsequent regulatory agency authorizations for future stream crossings and restoration of the Ravine.

Both the County and NorCal believes that this Plan is consistent with the definition of a Minor Modification, as defined in BCC §13‐103, because the proposed changes primarily serve to address corrective measures recommended within the County’s 2018 Inspection Report, and do not represent a substantial change to the activities described in the original RP 78‐99 or to the goals and terms contained within it. NorCal’s operations continue to be conducted pursuant to vested rights and the objectives for reclamation are well‐established by the original RP 78‐99 and County file for the Mine. This Plan is consistent with the goals of the original RP 78‐99 for a return to gently rolling foothills. Reclamation activities would continue to remove the non‐native Cherokee hydraulic mine tailings that have washed down into the Ravine and restore the property to a more natural state over time.

As part of the Plan modification, NorCal proposes no increase in production levels, no changes in the existing methods of mining (other than better tracking of the annual progress of reclamation through implementation of the new grading plan), and no new increase in areas approved for mining beyond those disturbances that have already occurred. Reclamation activity would not result in new significant environmental effects or a substantial increase in the severity of previously identified environmental effects. Instead, this Plan will ensure beneficial reclamation of areas that are not explicitly denoted in the original RP 78‐99 (where no explicit reclamation performance standards were previously described).

This Plan addresses reclamation pursuant to SMARA and its implementing regulations for those areas subject to vested mining rights including those areas originally covered under RP 78‐99. Consistent with PRC §2773(a), this Plan is specific to these properties and based upon the

Pentz Pit Mine Reclamation Plan 3 January 2021

character of the site and surrounding areas. Site‐specific performance standards are included for evaluating compliance with this Plan.

Consistent with SMARA Public Resources Code (“PRC”) §2712, this Plan has been developed to assure that:

(a) Adverse environmental effects are prevented or minimized and that mined lands are reclaimed to a usable condition which is readily adaptable for alternative land uses. (b) The production and conservation of minerals are encouraged, while giving consideration to values relating to recreation, watershed, wildlife, range and forage, and aesthetic enjoyment. (c) Residual hazards to the public health and safety are eliminated.

While the purpose of this Plan is to describe reclamation activities, ongoing vested surface mining activities (e.g., excavation, material handling and aggregate processing) are also described and referenced throughout for contextual purposes.

2.0 SURFACE MINING AND RECLAMATION ACT REQUIREMENTS

2.1 Description of Mining Operations

2.1.1 Name and Address of Operator and Agent [PRC §2772(c)(1)]

Operator:

NorCal Sand and Rock, Inc. P.O. Box 8107 Chico, CA 95927

Contact: Michael Hickerson Telephone: 503.855.8811 Email: mhickerson@ncsr‐co.com

2.1.2 Quantity and Type of Mineral to be Mined [PRC §2772(c)(2)]

Moving forward, approximately 1.2 million cubic yards of aggregates consisting of sand and gravel is anticipated be mined. These aggregates were deposited in the Ravine as hydraulic mining tailings from the historic Cherokee mine. Of this total, up to 15% (or 0.2 million cubic yards) is anticipated to be discharged to silt ponds as aggregate process wash losses. The remaining 1.0 million cubic yards (1.65 million tons at 1.65 tons per cubic yard) is anticipated to be produced as saleable product. The recoverable aggregate varies in gradation from fine sand to coarse gravel about 12 inches in diameter. As originally documented in RP 78‐99, the Mine is anticipated to produce up to 250,000 cubic yards per year.

Pentz Pit Mine Reclamation Plan 4 January 2021

2.1.3 Initiation and Termination Dates [PRC §2772(c)(3)]

Surface mining operations are active and have been continuous since 1970 or earlier. The estimated termination date for the surface mining operation is December 31, 2031, depending on market conditions. This date is based on an estimated forward‐looking annual average production rate of 150,000 tons per year.

2.1.4 Maximum Anticipated Depth of Mining [PRC §2772(c)(4)]

The maximum anticipated depth of the surface mining operation is generally ±40 feet below ground surface (“bgs”) to a maximum bottom elevation of 410 feet msl in the west pit area (see Sheets 2 and 3). However, in order to conform the east pit area side slopes to the surrounding topography, the height of the reclaimed slope on the south side of the east pit area may be left at ±80 feet (measured from crest to toe).

While this Plan reflects best available data, development of the mine excavations may vary due to geologic, engineering, economic, and/or market conditions. As such, mining operations may or may not reach the maximum depths and/or extents shown, and final reclamation contours may vary throughout the site. Reclamation would, in any case, be completed according to the standards described later in this Plan. Deviations from the Plan would be evaluated pursuant to 14 CCR §3502(d).

2.1.5 Reclamation Plan Map Requirements [PRC §2772(c)(5)]

2.1.6 Mining Description and Time Schedule [PRC §2772(c)(6)]

Mining Methods

The Mine is an open pit sand and gravel mine. No blasting is necessary. Mining/reclamation operations will continue to progress with the removal of limited vegetation and soils that may lie above marketable sand and gravel deposits. These vegetative and soil materials are only present in limited locations and in limited quantities, since any native soils have either been covered by Cherokee mine tailings or historically been washed downstream. Overlying materials, when encountered, are removed using excavators and/or scrapers aided by a motor grader and bulldozer as needed. As overburden is encountered, it will be directly placed or stockpiled for later use to build berms and haul roads, cap silt ponds, and prepare a revegetation substrate. After overlying materials are removed, sand and gravel is excavated using conventional earthmoving equipment such as front‐end loaders, hydraulic excavators, and bulldozers. Following excavation, the sand and gravel is transported by truck to the existing processing plant where it is processed and sold as construction materials.

Equipment Use

Equipment employed at the site includes conventional scrapers, excavators, front‐end loaders, motor graders and bulldozers. Haul trucks are used to transport materials from excavation areas to the processing plant. Aggregate processing operations employ conventional sand and gravel processing equipment, such as scrubbers (to wash aggregates), screens (to wash and sort aggregates), crushers (to resize and reshape materials), conveyors (to move material between processing plant components and stockpiles), and bins (for storage). Support equipment includes, but is not limited to, water trucks (for dust control), truck scales, portable and submersible water pumps, service/maintenance vehicles, trucks, cranes, loaders and fork‐lifts.

Schedule for Completion of Mining and Commencement of Reclamation

NorCal will continue yto carr out reclamation at the earliest possible time on those portions of the mined lands that will not be subject to further surface mining disturbances. Depending on seasonal site conditions, mining may occur in both the east and west pit areas separately or at the same time. Final reclamation, consisting of slope reclamation, revegetation and equipment removal will generally commence as soon as final grades are achieved. An estimated time schedule for mining and the commencement of reclamation is provided in Table 1, below.

Pentz Pit Mine Reclamation Plan 6 January 2021

TABLE 1 ANTICIPATED PROGRESSION OF MINING AND RECLAMATION Mining Mining Reclamation Reclamation Area (Start) (End) (Start) (End) 1. East Pit Active 2031 Ongoing 2034 2. West Pit Active 2031 Ongoing 2034 3. Processing Plant ‐‐ ‐‐ 2031 2034 Notes: 1. Anticipated mining schedule assumes annual production of approximately 150,000 tons per year. 2. Anticipated progression is approximate only. Actual timelines will vary depending on market and geologic conditions. 3. The reclamation end date includes three years for monitoring.

This anticipated sequence and schedule is dependent upon many factors such as securing regulatory entitlements, fluctuations in market demands, and need for specific aggregate products. The reclamation end dates listed represent the anticipated date by which physical reclamation activity will be complete. In addition to market conditions, monitoring periods for specific aspects of reclamation (e.g., revegetation monitoring) may extend the final date of reclamation sign‐off beyond these dates.

2.1.7 Public Health and Safety (Exposure) [CCR §3502(b)(2)]

Implementation of this Plan is not anticipated to jeopardize public health and safety during mining or reclamation activity. The Mine is located on private property and the public is neither presently exposed to the active operating areas at the site, nor will be during mining or reclamation activity. All visitors to the site are required to sign‐in and undergo site‐specific safety training as appropriate. Safety measures such as fencing, signs, and setbacks are employed to ensure safety and restrict access. No portals, shafts, tunnels or other openings to underground workings are mapped or proposed.

2.2 End Land Use

2.2.1 Proposed or Potential End Uses [PRC §2772(c)(7)]

The planned post‐mining end use is gently rolling foothills, which is consistent with the original conditions of the site and the end use approved under RP 78‐99. NorCal’s operations continue to reclaim the site by removing the non‐native Cherokee hydraulic mine tailings that have washed down and filled portions of the Ravine. In doing so, NorCal plans to restore the property to a more natural, native terrain over time.

The owner’s acknowledgment of the end use is evidenced by their consent to file application for this Plan (see Appendix B, Owner’s Acknowledgement of Proposed End Uses).

Pentz Pit Mine Reclamation Plan 7 January 2021

2.2.2 Reclamation Measures Adequate for the End Use [PRC §2772(c)(8)]

As detailed later in this Plan, reclamation will generally involve the following actions to support the planned end use:

1. Finish grading of pit slopes and surrounding areas to Plan specifications. 2. Decommissioning and removal of aggregate processing plant facilities, conveyors and mining equipment. o The following may be left to facilitate the planned end use: office trailer, fencing, perimeter and screening berms, site access roads, groundwater wells, and utilities. 3. Decommissioning of temporary interior access roads by removing road base materials (where present). 4. Redistributing stockpiled topsoil/growth media (if any) in preparation for revegetation. 5. Ripping, discing and/or scarifying disturbed areas as needed to relieve compaction and remove rills or other surface irregularities to establish a suitable root zone in preparation for revegetation. 6. Revegetation with native seed mixes as set forth in this Plan. 7. Implementation of best management practices as needed to minimize erosion and sedimentation pursuant to applicable standards. 8. Collecting and disposing of any incidental refuse or garbage in accordance with applicable standards.

2.2.3 Impact of Reclamation on Future Mining in the Area [PRC §2772(c)(9)]

Implementation of this Plan will not preclude future mining in the area ife marketabl resources are found, subject to first obtaining necessary approvals to do so.

2.3 Environmental Setting [CCR §3502(b)(1)]

2.3.1 Site Location

The site is located at 4970 Slickens Road in unincorporated Butte County along the boundary between the base of the Sierra Nevada foothills and the eastern edge of the Sacramento Valley floor in Butte County, California (USGS Cherokee 7.5 minute quadrangle). See Figure 1. The Plan boundary is located within Township 21 North, Range 3 East (Sections 25 and 30) and Range 4 East (Section 30), Mt. Diablo Base and Meridian. The Mine site office is located at Latitude 39.639o and Longitude ‐121.586o.

2.3.2 Assessor Parcels, Zoning and General Plan Designations

The Assessor Parcel Numbers within the Plan boundary are shown on Table 2, below. The Butte County General Plan designates the site as “Agriculture” and the site’s current zoning

2.3.3 Access and Utilities

Access roads, waterways and utilities are shown on Figure 2 as well as Sheets 1 and 2. Access to the site is currently provided via the main entrance at Wheelock Road. On‐site utilities include power and water from an on‐site well.

The access points and roads that will remain are shown on Sheets 1 and 2.

2.3.4 Geology

The Mine is located on an aggregate fan of mine tailings deposited along the boundary between the base of the Sierra Nevada foothills and the eastern edge of the Sacramento Valley floor in Butte County, California (USGS Cherokee 7.5 minute quadrangle). See Figure 3. The tailings are believed to have been deposited primarily from the Cherokee hydraulic mine approximately one mile to the east and upstream of the site. In addition to these tailings, the northern portion of the site is mapped as Chico Formation (Kc), frome th Late Cretaceous period, comprised of fossiliferous marine sandstone; lenticular beds of pebble to cobble conglomerate; and minor siltstone.

2.3.5 Soils

Table 3 below summarizes the soil units mapped for the site by the Natural Resources Conservation Service. The distribution of these soil types across the property is shown on Figure 5, NRCS Soils Map. Approximately 95 percent of the Mine is mapped as Typic Xerofluvents, sandy‐skeletal, 0 to 2 percent slopes. Significant quantities of topsoil are not expected to be encountered in carrying out the objectives of this Plan.

Pentz Pit Mine Reclamation Plan 10 January 2021

2.3.6 Seismicity

There are no active faults mapped within the Plan boundary and the site is not within an Earthquake Fault Zone as mapped by the California Geological Survey. Therefore, the potential for ground rupture due to onsite active faulting is considered low. The closest known active fault is the Bangor fault zone located to the southeast of Oroville (California Geologic Survey).

2.3.7 Biological Resources and Communities

Biological Resources Services, LLC (“BRS”) assessed the potential for sensitive biological communities, special‐status plant and wildlife species, and sensitive biological resources at the site (see Appendix C, Biological Resources Analysis). BRS completed field assessments in January 2020. No designated critical habitat for federally threatened or endangered species are located on site. BRS also conducted a preliminary delineation of Waters of the United States for the site (see Appendix D, Aquatic Resources Delineation Map). The key findings of BRS’ biological and aquatic resources assessments are summarized below.

Vegetative Communities

Based on the results of BRS’ assessment, the Plan boundary supports 13 plant communities that consist of:

1. Annual grassland 2. Chaparral 3. Foothill pine‐interior live oak woodland 4. Blue oak woodland 5. Valley oak‐sycamore riparian forest 6. Cottonwood riparian woodland 7. Willow riparian scrub 8. Settling ponds 9. Fresh water pond 10. Quarry pond 11. Mining related depression 12. Ruderal 13. Developed

These communities provide habitat to a number of common species of wildlife and may provide suitable habitat for certain special‐status plant and wildlife species. Historic mining activities have disturbed many of these communities but reclamation activities are expected to improve

Pentz Pit Mine Reclamation Plan 11 January 2021

the functions and values of these habitats over time as the property is restored to a more natural state.

Special Status Plant Species

Based on the results of BRS’ assessment, the following special‐status plant species have potential to occur in the Plan area:

1. Big‐scale balsamroot (Balsamorhiza macrolepis). CNPS List 1B.2. 2. Dissected‐leaved toothwort (Cardamine pachystigma var. dissectifolia). CNPS List 1B.2. 3. White‐stemmed clarkia (Clarkia gracilis ssp. albicaulis). CNPS List 1B.2. 4. Mildred’s clarkia (Clarkia mildrediae ssp. mildrediae). CNPS List 1B.3. 5. Mosquin’s clarkia (Clarkia mosquinii). CNPS List 1B.1. 6. Clifton’s eremogone (Eremogone cliftonii). CNPS List 1B.3. 7. California satintail (Imperata brevifolia), CNPS List 2B.1. 8. Red Bluff dwarf rush (Juncus leiospermus var. leiospermus). CNPS List 1B.1. 9. Colusa Layia (Layia septentrionalis). CNPS List 1B.2. 10. Ahart’s Paronychia (Paronychia ahartii). CNPS List 1B.1. 11. California Beaked‐Rush (Rhynchospora californica). CNPS List 1B.1. 12. Brownish Beaked‐Rush (Rhynchospora capitellata). CNPS List 2B2. 13. Sanford’s Arrowhead (Sagittaria sandfordii). CNPS List 1B2. 14. Butte County Checkerbloom (Sidalcea robusta). CNPS List 1B.2.

However, none of these species were observed on the site.

Special Status Wildlife Species

Based on the results of BRS’ assessment, special‐status wildlife species could potentially occur in the annual grassland, chaparral, woodland, riparian, and seasonal wetland habitats supported by the Study Area. In addition, some state‐protected raptors could forage on the area. The following special status wildlife species may have potential to occur on site:

Invertebrates

1. Vernal Pool Fairy Shrimp (Branchinecta lynchi). Federally Threatened. 2. Vernal Pool Tadpole Shrimp (Lepidurus packardi). Federally Endangered. 3. California Linderiella (Linderiella occidentalis). Federal Species of Special Concern. 4. Valley elderberry longhorn beetle (Desmocerus californicus dimorphus). Federally Threatened.

Pentz Pit Mine Reclamation Plan 12 January 2021

The seasonal and emergent wetland habitats and mining related depressions within the Plan area may provide suitable conditions to support the vernal pool fairy shrimp, vernal pool tadpole shrimp, and California linderiella. However, no further mining‐related activities are planned in these areas. The Study Area does not occur within designated critical habitat for vernal pool fairy and tadpole shrimp. None of these species were observed on site and no impacts to these species are expected as a result of reclamation.

While two elderberry shrubs were found within the Plan area, BRS carefully examined the stems of both shrubs for the presence of exit holes that may indicate presence of the valley elderberry longhorn beetle – no exit holes were detected.

Amphibians

1. Foothill Yellow‐Legged Frog (Rana boylii). Federal Species of Special Concern, California Species of Special Concern. Not observed.

The relatively high‐velocity flows observed within the intermittent stream associated with the Ravine may preclude the presence of Foothill Yellow‐legged frog within the Plan area. However, lower velocity tributaries into this system, as well as lower down the valley floor towards, and in, Dry Creek, may provide potentially suitable habitat for this species. Protocol‐level surveys would need to be conducted to determine presence/absence of this species prior to performing work in these areas.

Reptiles

1. Northwestern Pond Turtle (Actinemys marmorata). California Species of Special Concern. Not observed.

The mosaic of slow‐moving mine tailing streams and historic settling ponds in the willow riparian scrub habitat located in the far western portion of the Plan area could provide potentially suitable habitat for this species. However, mining is not planned in these areas.

Birds

1. Cooper’s Hawk (Accipiter cooperii) and Sharp‐shinned Hawk (Accipiter striatus); State Protected. Not observed. 2. Tricolored Blackbird (Agelaius tricolor). Federal Species of Special Concern, California Species of Special Concern. Not observed. 3. Golden Eagle (Aquila chrysaetos). California Species of Special Concern, State Protected. Present. 4. Red‐Shouldered Hawk (Buteo lineatus). State Protected. Present.

Pentz Pit Mine Reclamation Plan 13 January 2021

Mammals

1. Western mastiff bat (Eumops perotis californicus); California Special Concern species. Not observed. 2. Silver‐haired bat (Lasionycteris noctivagans), California Special Concern species. Not observed.

Fisheries

No special‐status fisheries are present or have potential to occur at the site. While delta smelt were identified on the USFWS IPaC Letter as potentially occurring in the vicinity of the Plan area, the Plan area does not provide suitable aquatic habitat for this species.

2.3.8 Hydrology

Groundwater

No mining is planned in groundwater. Groundwater elevations are expected to vary depending upon the amount and intensity of rainfall in the area. Based on estimates found in the report titled Spring & Fall 2019 Groundwater Level Conditions, published by Butte County Water and Resources Conservation, groundwater may occur within 15 feet below ground surface in the lower elevation of the site. A freshwater pond that was formerly excavated into groundwater serves as a source of make‐up water for the processing plant. Water used in processing aggregates is recycled and none is wasted.

Regulated Wetlands and Waters

BRS conducted a preliminary jurisdictional determination (PJD) of wetland and “other waters” in January 2020, which identified the presence of regulated waters of the U.S. within the Plan area. A small portion of Dry Creek crosses through the Plan area along the far western boundary, and an unnamed intermittent stream associated with Sawmill Ravine occurs throughout the length of the Plan area flowing in an east‐to‐west direction. Various mining related depressions and ephemeral drainages are also present in portions of the Plan area. Some of these features may be considered jurisdictional by either the U.S. Army Corps of Engineers (“USACE”), California Department of Fish and Wildlife (“CDFW”) and/or Regional Water Quality Control Board (“RWQCB”). If so, any proposed mining activities associated within said features would be subject to permits from these agencies.

Based on information obtained during the January 2020 field delineation, BRS determined that there are a total of 37.785 acres of potentially jurisdictional wetland features mapped within the Study Area (see Appendix D). Of this total, 0.013 acres were mapped as seasonal wetland, 0.855 acres were mapped as emergent wetlands, and 36.917 acres were mapped as willow riparian scrub. There are also approximately 11.089 acres/8820.1 linear feet of “other waters” associated with Dry Creek and Sawmill Ravine that are potentially jurisdictional. The vast majority of these waters will be avoided.

Pentz Pit Mine Reclamation Plan 14 January 2021

The Plan area also contains “other waters” comprised of active industrial ponds and mining related depressions, which should not be jurisdictional pursuant to 33 CFR §328.3. As stated in 33 CFR §328.3, water‐filled depressions created in dry land incidental to mining or construction activity including pits excavated for obtaining fill, sand, or gravel that fill with water would not meet the definition of waters of the U.S.

2.4 Effect on Surrounding Land Uses [CCR §3502(b)(1)]

2.4.1 Surrounding Land Uses

The predominant land uses in the general vicinity of the site are aggregate mining, open space, cattle grazing, and very low density rural residential. The reclaimed Lucky 7 mine, which was once a part of the original Pentz Pit mine boundary, is located to the north of the site.

2.4.2 Effect that Reclaimed Site Conditions May Have on Surrounding Land Uses

As described above, the planned end use for the Mine is gently rolling foothills, which is consistent with the original conditions of the site and the end use approved under RP 78‐99. NorCal’s operations will continue to reclaim the site by removing the non‐native Cherokee hydraulic mine tailings that have washed down and filled portions of the Ravine. In doing so, NorCal plans to restore the property to a more natural, native terrain over time. Accordingly, as compared to present conditions at the site, implementation of this Plan should have a beneficial (rather than adverse) effect on surrounding land uses.

2.5 Slope Stability and Disposition of Fill Materials

2.5.1 Final Slopes; Slope Angles Flatter than Critical Gradient [CCR §3502(b)(3)]

CCR §3704(f). Final cut slopes have minimum factor of safety for end use and conform with surrounding topography and/or approved end use.

Final cut slopes will be left at 2H:1V or flatter and conform to surrounding topography to the extent practicable (see Sheets 2 and 3). The finish slope angles are flatter than the natural angle of repose of the material, as evidenced by steep standing slope faces along the north and south sides of the east pit area. These finish slopes are adequate for the planned end use.

2.5.2 Fill Slopes and Compaction Standards

CCR §3502(b)(4). The source and disposition of fill materials used for backfilling or grading shall be considered in the reclamation plan. Where end uses are sensitive to settlement, include compaction of the fill materials in conformance with good engineering practice.

CCR §3704(a). For urban use, fill compacted in accordance with UBC, local grading ordinance, or other methods approved by the lead agency.

Pentz Pit Mine Reclamation Plan 15 January 2021

CCR §3704(b). For resource conservation, compact to standard for that end use.

CCR §3704(d). Final reclamation fill slopes not exceed 2:1, except when allowed by site‐ specific engineering analysis, and can be revegetated.

CCR §3704(e). At closure, final landforms of fills conform with surrounding topography and/or approved end use.

Final reclamation fill slopes, if any, will not exceed 2H:1V. Backfills should not be necessary to achieve the design finish slopes. Backfill for urban uses, human occupancy, or resource conservation purposes is also not proposed. Final landforms have been specifically designed to be suitable for the planned end use.

2.6 Hydrology and Water Quality

2.6.1 Surface and Groundwater Quality Protected in Accordance with Porter‐Cologne and Clean Water Acts [CCR §3710(a)]

CCR §3706(a). Mining and reclamation to protect downstream beneficial uses.

CCR §3706(b). Water quality, recharge, and groundwater storage that is accessed by others shall not be diminished, except as allowed by plan.

CCR §3503(b)(2). Substantially prevent siltation of groundwater recharge areas.

Surface and groundwater will continue to be protected from siltation and pollutants as required by the Federal Clean Water Act, the California Porter‐Cologne Water Quality Control Act, County ordinances, RWQCB and the State Water Resources Control Board.

The Operator will comply with National Pollutant Discharge Elimination System (“NPDES”) Industrial Storm Water General Permit requirements, including implementation of a Storm Water Pollution Prevention Plan (“SWPPP”) with Best Management Practices (“BMPs”) to control erosion, sedimentation, and pollution. As required, the Operator will also implement a Spill Prevention, Control, and Countermeasure Plan (“SPCC Plan”) and Hazardous Materials Business Plan pursuant to 40 CFR Part 112 and 19 CCR Section 2729, respectively.

Surface mining and reclamation activities are not expected to affect downstream beneficial uses of water, or the quality of water, recharge potential, or storage capacity of groundwater aquifers. Based on the anticipated maximum depth of excavation (to elevation 410 feet msl), groundwater is not expected to be encountered and a buffer of up to 15 feet should exist between groundwater levels and the fully developed mine floor. Water used in processing aggregates is recycled and none is wasted. Water lost through evaporation or incorporated into product is replaced from a freshwater pond that was formerly excavated in groundwater (see Figure 2 for the location of this pond).

Pentz Pit Mine Reclamation Plan 16 January 2021

2.6.2 Drainage, Sediment and Erosion Control [PRC §2773(a)]

CCR §3503(a)(3). Erosion control facilities constructed and maintained where necessary.

CCR §3503(b)(1). Settling ponds used where they will provide significant benefit to water quality.

CCR §3503(e). Grading and revegetation to minimize erosion and convey surface runoff to natural drainage courses or interior basins. Spillway protection.

CCR §3706(c). Erosion and sedimentation controlled during all phases of construction, operation, reclamation, and closure of surface mining operation to minimize siltation of lakes and water courses per RWQCB/SWRCB.

CCR §3706(d). Surface runoff and drainage controlled to protect surrounding land and water resources. Erosion control methods designed for not less than 20 year/1 hour intensity storm event.

CCR §3706(e). Altered drainages shall not cause increased erosion or sedimentation.

Drainage and Erosion Control

This Plan is designed to minimize erosion and retain direct precipitation and run‐on in the interior mining areas. As required by CCR §3706(d), erosion control methods have been designed for the 20 year/1 hour intensity storm event (see Sheet 1, Note 4). Surface runoff will be allowed to collect in the mine floor before it evaporates, infiltrates, or is used on‐site (e.g., for dust control).

The Operator will comply with the NPDES General Permit requirements by implementing a SWPPP that includes BMPs to control erosion, sedimentation, and pollution. These measures will ensure that water courses are protected from erosion, gullying, sedimentation and potential contamination. Slopes will be vegetated with appropriate native seed mixes once final reclamation grades are achieved.

Settling Ponds and Basins (CCR §3503(b)(1))

This Plan incorporates the continued use of settling ponds to capture and settle aggregate process wash fines (or silts) from the aggregate production process as is typical of aggregate mines. Settling ponds have been used at the site since the onset of aggregate processing activities. See Figure 2 for the location of settling ponds. The Operator will continue to use the settling ponds until they reach capacity, at which time the ponds will be revegetated. The use of settling ponds will continue to minimize the potential sedimentation of Dry Creek (downstream of the site).

Pentz Pit Mine Reclamation Plan 17 January 2021

2.6.3 Contaminant Control and Mine Waste Disposal [PRC §2772(c)(8)(A)]

CCR §3503(a)(2). Overburden stockpiles managed to minimize water and wind erosion.

CCR §3503(d). Disposal of mine waste and overburden shall be stable and not restrict natural drainage without suitable provisions for diversion.

CCR §3712. Mine waste and tailings, and mine waste disposal units governed by SWRCB/IWMB (Article 1, Subchapter 1, Chapter 7, Title 27, CCR).

Mine waste will be limited to wash fines (silts) generated from aggregate processing, and general refuse/trash. Wash fines will eventually fill the silt ponds for a return to gently sloping land in these areas. Surplus wash fines, if any, may be blended with other native substrate materials as a soil upgrade. Wet wash fines will not be used for any construction or engineer fill applications. General refuse/trash will be hauled and disposed of off‐site in accordance with applicable standards.

Settling pond areas have been designed for a generally even profile. Fill slopes, perimeter berms, and temporary stockpiles will be seeded and wetted as needed to minimize water and wind erosion, and will not restrict natural drainage courses. No material stockpiles will be left following reclamation. However, any berms installed for safety along roads may be left in place to promote safe access across the property following reclamation.

2.6.4 In‐stream Activities [CCR §3710(b)]

PRC §2772(c)(8)(B). Rehabilitation of streambanks/beds to minimize erosion.

CCR §3502(b)(6). Temporary stream and water diversions shown.

CCR §3706(f)(1). Stream diversions constructed in accordance with Fish and Game Code.

CCR §3706(f)(2). Stream diversions constructed in accordance hwit Federal Clean Water Act and Rivers and Harbors Act of 1899.

CCR §3706(g). All temporary stream diversions eventually removed.

CCR §3710(c). In‐stream channel elevations and bank erosion evaluated annually using extraction quantities, cross‐sections, aerial photos.

CCR §3710(d). In‐stream mining not cause fish to be trapped in pools or off‐channel pits, or restrict migratory or spawning activities.

Reclamation will involve the removal of historic Cherokee mine tailings from portions of the site and the Ravine. To accomplish this reclamation objective, limited in‐stream excavation may need to occur.

Pentz Pit Mine Reclamation Plan 18 January 2021

In order to implement the Plan to the full extents of the design reclamation contours, temporary stream crossings and a temporary stream diversion of a portion of the Sawmill Creek may be needed to direct dry season flows around the reclamation footprint and back into the channel downstream. The location of an existing temporary stream crossing is shown on Figure 2. The temporary crossings would be developed with culverts and removed by October of each year (i.e., the rain season). All temporary stream crossings will be removed prior to the completion of reclamation.

The temporary stream diversion would be more specifically located in the future at the time it is needed and would be constructed in accordance with a Lake and Streambed Alteration Agreement between the Operator and CDFW in accordance with Fish and Game Code. The diversion may also be subject to the jurisdiction of the USACE, who would ensure through Department of the Army 404 permit authorizations that any necessary diversions are conditioned to comply with the Federal Clean Water Act. The Rivers and Harbors Act is not applicable. Any temporary diversions would be removed prior to the completion of reclamation.

Any extraction of sand and gravel from the wetted portion of the stream associated with the Ravine will be conducted and closely monitored by the Operator to control channel degradation and prevent increased stream bank erosion. These extraction activities would occur only after appropriate authorizations are obtained from the applicable regulatory authorities. There are no nearby bridge supports, pipelines, structures buried within the channel, or spawning habitats that would be affected. Riparian vegetation downstream of the east pit mining area in what has been mapped as riparian scrub habitat has naturally restored itself following decades of mine and reclamation‐related disturbances (as clearly shown in the aquatic resource delineation map included in Appendix D). Changes in channel elevations and bank erosion will be evaluated annually using records of annual extraction quantities and benchmarked annual cross‐sections and/or sequential aerial photographs to determinate appropriate extraction locations and rates. This information will be made available to the County upon request.

In‐stream activities would not cause fish to be trapped or restrict migratory or spawning activities, as the site does not support habitat for fisheries.

2.7 Protection of Fish and Wildlife Habitat [CCR §3503(c)]

CCR §3703(a). Sensitive species conserved or mitigated.

CCR §3703(b). Wildlife habitat at least as good as pre‐project, if approved end use is habitat.

CCR §3703(c). Wetlands avoided or mitigated at 1:1 minimum.

CCR §3704(g). Piles or dumps not placed in wetlands without mitigation.

Pentz Pit Mine Reclamation Plan 19 January 2021

The Plan footprint is permitted for surface mining disturbances pursuant to vested rights and reclamation entitlements. Nearly all of the Plan boundary has already been disturbed by past and present surface mining activity. Limited additional habitat would be disturbed.

Although reclamation to an end use of wildlife habitat is not proposed, implementation of this Plan will provide habitat functions and values that represent a vast improvement compared to existing conditions at the site. The small stream associated with the Ravine in the Plan area is a highly degraded and disturbed system resulting from the deposition of historic tailings from the Cherokee mine to the east. Hydrologic alterations within the Ravine and in adjacent areas have potentially altered stream flow, bank condition, and riparian vegetation as compared to historical conditions. However, as approved under RP 78‐99, NorCal’s operations will continue to remove the non‐native Cherokee tailings that have filled portions of the Ravine and in turn restore the property to a more natural, native terrain over time.

Habitat disturbances associated with carrying out the objectives of this Plan will primarily be associated with the in‐stream activities including a potential dry season diversion of a portion of the intermittent stream associated with the Ravine. These activities will be the subject of regulatory review and oversight, including review by regulatory agencies (e.g., USACE, U.S. Fish and Wildlife Service, RWQCB and CDFW) who may impose specific measures for avoidance, minimization, or mitigation of potential impacts. Where wetland features are present, they will either be avoided or mitigated at 1:1 minimum ratios. No fills will be placed in wetlands without proper authorizations. For any sensitive avian species, active nests will be avoided during the nesting season or appropriate mitigation will be implemented as required by the responsible regulatory agency.

To ensure compliance with CCR Section e3703, th Operator will append any permit conditions of approval and mitigation measures that relate to reclamation of mined lands to this approved Plan, pursuant to PRC Section 2772.1(b)(7)(B). Appendix E, Reclamation Related Conditions of Approval [Reserved], is included as a placeholder for this purpose.

Ultimately, the site will be reclaimed with native habitats that better resemble conditions that once existed prior to the deposition of Cherokee mine tailings. Accordingly, as compared to present conditions at the site, implementation of this Plan should have a beneficial (rather than adverse) effect on on‐site habitats.

Based on recommendations presented by BRS, the Operator will implement the following specific measures to further protect species and habitats:

1. Implementation of a SWPPP with BMPs, such as silt fencing and check‐dams, to reduce the potential for erosion turbidity. 2. To avoid impacts to nesting birds, the removal of tree, shrub and/or herbaceous vegetative cover ify an will generally occur outside the breeding season, which is typically between (January) 15 February and August 30 of each year.

Pentz Pit Mine Reclamation Plan 20 January 2021

3. A nesting raptor survey will occur 72 hours prior to the removal of vegetation to determine presence/absence of nesting raptor species. If any active raptor nests are found, then mining‐related activity will maintain a buffer of at least 150 feet around the nest during the breeding season from March to August and the area will be protected until August 15 or until the young have fledged (typically 3 to 4 weeks). 4. A protocol‐level Foothill yellow‐legged survey would be conducted to determine presence/absence of this species prior to performing work in any new areas containing low velocity ephemeral drainage tributaries or reclamation activity adjacent to Dry Creek. Should any mining activities take place near any confirmed species, a reasonable buffer to be determined in consultation with CDFW will be maintained until appropriate authorizations are obtained or activity no longer occurs in that area. 5. A protocol‐level preconstruction floristic survey will be performed prior to any new mining disturbances to identify the location of any listed special‐status plants. Should any mining activities take place near any confirmed listed plant species, a reasonable buffer to be determined in consultation with CDFW will be maintained until activity no longer occurs in that area.

2.8 Resoiling [CCR §3503(f)]

CCR §3704(c). Mine waste stockpiled to facilitate phased reclamation and separate from growth media.

CCR §3503(a)(1). Removal of vegetation and overburden preceding mining kept to a minimum.

CCR §3711(a). All salvageable topsoil removed. Topsoil and vegetation removal not precede mining by more than one year.

CCR §3711(b). Topsoil resources mapped prior to stripping, location of stockpiles on map. Topsoil and growth media in separate stockpiles.

CCR §3711(c). Soil salvage and phases set forth in plan, minimize disturbance, designed to achieve reveg success.

CCR §3711(d). Topsoiling phase ASAP. Topsoil stockpiles not be disturbed until needed. Topsoil stockpiles clearly identified and planted with vegetation or otherwise protected.

CCR §3711(e). Topsoil redistributed in stable site and consistent thickness.

CCR §3707(b). Segregate and replace topsoil by horizon.

CCR §3705(e). Soil altered or other than native topsoil, requires soil analysis. Amend if necessary.

Pentz Pit Mine Reclamation Plan 21 January 2021

Based on the site‐specific soils information, growth media for revegetation will likely be limited to native sands and soils that may be located below the Cherokee mine tailings after final excavation grades are achieved. As originally described in RP 78‐99, the majority of topsoil that may have existed at the onset of reclamation operations (dating at least as far back as 1970) has either been washed downstream or covered by the historic Cherokee mine tailings. As excavations progress to the original ground contours on off channel areas native soil may be exposed. At this point the excavations for aggregate recovery would stop and the native soil could serve as a suitable revegetation substrate. No resoiling or revegetation is planned in‐ stream.

Figure 5 indicates that mining areas are overlain by fluvent soils deposited by flood events, which are comprised of the Cherokee mine tailings. Lacking an abundance of traditional topsoil, the sand deposits likely constitute the best available substrate materials at the site. If necessary to achieve the planned end use, then these materials could be blended with wash fines (contained in the settling ponds) to enhance nutrient and water holding capacity of the soils.

Prior to revegetation, the Operator will generally handle soils and prepare a revegetation substrate in the following manner:

1. Remove soils only as necessary to access new mining areas and use them for reclamation as soon as it can be accommodated by the mining schedule.

2. Remove all salvageable topsoil, if any distinguishable topsoil horizon can be identified, as a separate layer. However, this is not expected based on the site‐specific soil conditions.

3. Limit topsoil and vegetation removal to not precede mining by more than one year, unless a longer time period is approved by the County.

4. Where possible, place soils that have been removed (if any) for direct use in reclamation. Where salvaged topsoil cannot be used immediately for reclamation, stockpile it separately from other overburden and do not disturb until needed for reclamation.

5. Install signage for topsoil stockpiles (if any) to keep them clearly distinguishable from other stockpiled materials.

6. Seed soil stockpiles with an appropriate seed mixture as needed to prevent water and wind erosion and to discourage weed growth (see erosion control seed mix in Section 2.9.1 below).

7. Prior to resoiling, rip, disc and/or scarify fill areas as needed to relieve compaction and remove rills, ruderal vegetation, or other surface irregularities.

8. Redistribute available topsoil (or surplus process wash fines) in preparation for revegetation, with a target thickness of 4 to 6‐inches of growth media atop other native substrate materials in the mine floor or on mine slopes.

Pentz Pit Mine Reclamation Plan 22 January 2021

o The thickness of soil redistributed on the site during reclamation will vary. The target thickness of 4 to 6‐inches is only a guideline based on available site specific soil information. It is possible that the existing sand deposit will represent the best available revegetation substrate for the site.

The site is not located on prime agriculture ground and reclamation to prime agriculture is not proposed; therefore, segregation and replacement of topsoil by horizons (CCR §3707(b)) is not required.

2.9 Revegetation [CCR §3705]

2.9.1 Vegetative Cover and Planting Procedures

CCR §3503(g). Revegetation and plant survival (use available research).

CCR §3705(a). Vegetative cover, suitable to end use, self‐sustaining. Baseline studies documenting cover, density and species richness.

CCR §3705(c). Decompaction of site.

CCR §3705(g). Use native plant species, unless exotic species meet end use.

CCR §3705(h). Plant during correct season.

CCR §3705(i). Use soil stabilizing practices and irrigation, when necessary to establish vegetation.

CCR §3707(d). Fertilizers and amendments not contaminate water.

This revegetation plan is specific to the property and includes site‐specific criteria for evaluations of compliance with this Plan’s revegetation objectives. Consideration has been given to the topography, resoiling characteristics (including limited soil availability), and climate of the mined areas. As disturbed areas become available for reclamation, revegetation will generally proceed in the following manner:

1. Substrate Preparation. As described in Section 2.8, each area to be re‐vegetated will be treated as necessary to create or improve the soil substrate. These measures will include scarification of existing substrate to relieve compaction as well as addition of any available growth media available at the site to areas that lack suitable soil substrate. Scarification may consist of discing, ripping, deep ripping, or a combination of these methods depending on the texture of the substrate and the extent of compaction.

2. Application of Herbicides. Application of herbicides may be used ahead of planting to minimize potential for weed growth.

Pentz Pit Mine Reclamation Plan 23 January 2021

3. Seeding. Following substrate preparation a seed mix (described below) will be applied via hydro‐seed (most effective for slopes) or broadcast seed method (suitable for other graded areas such as the reclaimed plant site and silt ponds). Ideally, hydroseeding will be conducted in the early fall season (October‐November) to take advantage of the natural rainfall for seed germination. The seed will be mixed with mulch, fertilizer and tackifier as needed for each situation.

4. Monitoring. A qualified biologist or botanist will monitor re‐vegetated areas annually for a minimum of three years to assess whether revegetation is proceeding successfully. Revegetation success will be judged pursuant to the performance standards outlined later in this Plan. The monitoring program shall be considered complete if during the last two years plantings required no human intervention. If intervention is necessary after the second year of monitoring, then remedial measures will be implemented and monitoring will continue until such time as the performance standards can be met or this Plan is modified in consultation with the County. Monitoring reports will summarize the reclamation responsibilities, construction and revegetation completed, monitoring implemented, and revegetation results compared to established success criteria. Photo documentation and field data will also be provided in appendices to the monitoring reports. If it is apparent that some reclamation features may not achieve intended success criteria, then potential remediation opportunities will be evaluated or suggested and provided in the report.

Although RP 78‐99 indicated that revegetation would occur with native seed as part of final reclamation, the plan provided no specific seed mix for this purpose. Table 4, below, provides a suitable revegetation seed mix to support the planned end use. This mix includes naturalized species that are suitable for dryland grazing to reduce future fire hazards at the site. In addition, the native substrate may contain a seedbank of other species that may germinate. The seeding is primarily proposed to ensure that there is sufficient grass cover to stabilize reclaimed areas for erosion control. The seed mix may be supplemented with other native species, such as wildflower, at the time of planting.

The species chosen for inclusion in the seed mixes are intended to be self‐sustaining without dependence on irrigation, or ongoing applications of soil amendments or fertilizers, provided that planting takes place in the fall and subsequent rainfall is not abnormally low. As such, irrigation should not be needed.

Notes: 1. Seed mix by Pacific Coast Seed. 2. Composition of seed mix (and appropriate modifications) to be determined based on availability from suppliers, cost, test plot results (if applicable) and species determined most suitable at the time of planting. 3. Ideally, revegetation will occur in early fall (i.e., October/November).

Soil Stabilizing Practices and Irrigation

Should any supplemental soil stabilizing practices be needed, straw mulch, fiber rolls, erosion control blankets and/or other BMPs will be used as necessary to control soil erosion.

2.9.2 Revegetation Test Plots [CCR §3705(b)]

A revegetation test plot for the revegetation seed mix will be placed at the previously mined areas to the south of the processing plant as shown on Sheet 1, unless the County waives the requirement to conduct test plots pursuant to 14 CCR § 3705(b). The test plot will be conducted simultaneously with ongoing mining and reclamation. The application rates for the seed xmi presented in Table 4 above may be adjusted based on the results of test plot monitoring to the extent required by and consistent with 14 CCR § 3705(b).

2.9.3 Revegetation of Roads and Traffic Routes

CCR §3705(d). Roads stripped of roadbase materials, resoiled and revegetated, unless exempted.

CCR §3705(f). Temporary access not bladed. Barriers installed.

The on‐site road network is planned to be left in place for safety, fire protection, and to facilitate the planned end use. However, any temporary interior access roads and stream crossings used to access mining areas will be removed. Barriers such as berms and k‐rails will continue to be used to restrict access around the mine to keep unauthorized vehicles out. No new temporary access routes are anticipated to be needed for reclamation.

2.9.4 Noxious Weed Management [CCR §3705(k)]

During the revegetation establishment period, noxious weeds will be managed: (1) when they threaten the success of the proposed revegetation; (2) to prevent spreading to nearby areas; and (3) to eliminate fire hazard. Noxious weeds will be removed using a combination of herbicides, mechanical controls, and hand weeding. In some cases, complete eradication may not be feasible unless the weed‐infested patches are small. Noxious weed identification and management will be an element of the revegetation monitoring period overseen by a qualified biologist.

Note: Noxious weeds are those weeds listed by the California Department of Food and Agriculture.

Pentz Pit Mine Reclamation Plan 25 January 2021

2.9.5 Plant Protection Measures, Fencing, Caging [CCR §3705(l)]

The proposed revegetation is not anticipated to require fencing, caging, or other plant protection measures, as grazing is not anticipated during the revegetation establishment period. To be sure, the site will not be grazed for at least the first two years following reclamation to protect initial seeding efforts and promote revegetation.

2.9.6 Revegetation Performance Standards and Monitoring [PRC 2773(a)]

CCR 3705(m). Success quantified by cover, density and species‐richness. Standards proposed in plan. Sample method set forth in plan and sample size provide 80 percent confident level, as minimum.

CCR §3705(j). If irrigated, demonstrate self‐sustaining without for two years minimum.

Reclamation will be measured against the following revegetation success criteria. As a reminder, irrigation is not proposed.

Cover / Density: Minimum 50% total cover (excluding noxious weeds)

Species richness: Minimum 2 species per 1 meter x 1 meter plot (excluding noxious weeds)

Noxious weeds: Not to exceed greater than 10% total cover

Note: Success criteria will be updated, if necessary, in consultation with the Lead Agency following monitoring of the proposed test plot.

Monitoring

Qualified biologists, botanists or revegetation specialists will monitor re‐vegetated areas annually for a minimum of three years after seeding to assess whether revegetation is proceeding successfully. Revegetation success will be judged pursuant to the performance standards presented above. Performance standards will only be considered to be met if the plantings required no human intervention during the preceding two years. If intervention is necessary after the second year of monitoring, then remedial measures will be implemented and monitoring will continue for another two years.

Qualitative Monitoring. Under most circumstances the success or failure of revegetated areas in relation to established performance standards should be immediately evident. In these circumstances, qualitative monitoring is sufficient documentation of the condition and cover of the revegetated areas. Qualitative monitoring consists of a visual determination of the percentage of cover of each plant species in each restoration area.

Quantitative Monitoring. Quantitative monitoring would only be conducted if revegetation monitors have significant doubt as to whether a particular area meets the standards outlined

Pentz Pit Mine Reclamation Plan 26 January 2021

above. In these cases, monitoring will include a minimum of twenty, 1 meter x 1 meter plots to determine total average cover, species richness, and noxious weed establishment. In each year that quantitative monitoring is conducted, square meter plots would be randomly placed in each reclamation unit (i.e., mine slopes, plant site, silt ponds). No less than 20 randomly located plots would be distributed across each site, and additional plots would be established as necessary to reach the 80 percent confidence interval. The locations of each plot would be recorded on a map or will be recorded using a GPS receiver.

2.9.7 Agricultural Fertility Performance Standards [CCR §3707 and CCR §3708]

CCR §3707(a). Return prime agriculture to fertility level specified in approved plan.

CCR §3707(c). Productivity rates equal pre‐project or similar site for two consecutive years. Rates set forth in plan.

CCR §3708. Other ag capable of sustaining crops common to area.

The Mine is not located on prime agricultural lands. Therefore, performance standards set forth in CCR §3707 (required for agriculture end uses on prime agricultural lands) do not apply.

Consistent with RP 78‐99, the Mine will be reclaimed to gently rolling foothills that may support cattle grazing. Therefore, the performance standards set forth in CCR §3708 for crop sustainability also do not apply.

2.10 Equipment Removal and Incidental Waste Disposal

CCR §3709(a). Equipment stored in designated area and waste disposed of according to ordinance.

CCR §3709(b). Structures and equipment dismantled and removed.

CCR §3502(b)(5). Disposition of old equipment.

Equipment used in mining and reclamation will be stored at the plant site shown on Sheet 1 and removed from the site following final reclamation.

All processing facilities, conveyors, and truck scale will be dismantled and removed as part of reclamation. Buildings (such as the office and shop buildings), fences and the road networks servicing the Mine may be left in place to facilitate the planned end use and promote access between properties.

Any incidental refuse or garbage will be collected, hauled off‐site and disposed of in accordance with state and local standards.

Pentz Pit Mine Reclamation Plan 27 January 2021

2.11 Closure of Portals, Shafts and Openings

CCR §3713(a). Drill holes, water wells, monitoring wells completed or abandoned in accordance with laws.

CCR §3713(b). All portals, shafts, tunnels, or openings, gated or protected from public entry, but preserve access for wildlife.

No portals, shafts, tunnels or other openings to underground workings are mapped or proposed. No drill holes (other than temporary drill holes that may be used for geologic exploration) are proposed. Any water wells or monitoring wells installed in support of surface mining or reclamation activities will be left in place to facilitate future use of the property or abandoned in accordance with state and local laws and regulations.

2.12 Administrative Requirements

2.12.1 Statement of Reclamation Responsibility [PRC §2772(c)(10)]

Please see Appendix F, Statement of Reclamation Responsibility.

2.12.2 Financial Assurances [PRC §2773.1]

Financial assurances are in place and will remain in effect for the duration of the mining operation and any additional period until reclamation is complete. The Operator’s Financial Assurance Cost Estimate (“FACE”) will continue to be updated annually and submitted to the County for review within 30 days of each of the County’s annual surface mining inspections. Financial assurances mechanisms (“FAM”), which provide financial security for reclamation requirements, may be adjusted (up or down as appropriate) based on the updated FACE.

2.12.3 Lead Agency Approvals and Annual Inspection [PRC §§2772.1 and 2774]

Upon Plan approval, and subsequent County and regulatory agency approvals for work in the wetted portions of the Ravine, the conditions of approval and/or mitigation measures pertinent to reclamation of mined lands will be added to this Plan pursuant to PRC §2772.1(b)(7)(B). Appendix E is included as a placeholder for this purpose.

The Operator will submit a Mining Operation Annual Report to DMR and the County. This report will summarize the previous year’s production and reclamation activities. SMARA also requires the County to conduct an annual inspection of the site to ensure compliance with the approved Plan.

2.12.4 All Mining Operations Since 1/1/76 Included in Reclamation Plan [PRC §2776]

No reclamation or reclamation plan approval is required for lands disturbed by surface mining operations conducted before January 1, 1976, which have not since been disturbed by surface

Pentz Pit Mine Reclamation Plan 28 January 2021

mining operations (SMARA §2776). All areas subject to mining operations since January 1, 1976 as well as areas planned to be disturbed in the future are included in this Plan.

2.12.5 Mining in 100‐year Floodplain and Within One Mile of State Highway Bridge [PRC §2770.5]

Mining will not occur within the 100‐year floodplain of Dry Creek as mapped by the Federal Emergency Management Agency (“FEMA”) on its Flood Insurance Rate Map (“FIRM”) No. 06007C0575E, which became effective January 6, 2011. Therefore, Caltrans notification is not required.

3.0 LEAD AGENCY REQUIREMENTS [PRC §2772(C)(11)]

Section 3.0 of this Plan addresses specific lead agency reclamation requirements, where it is believed those requirements either supplement or amplify the requirements of SMARA as outlined in Section 2.0. This part is not intended to restate or address every SMARA code section or policy related to the reclamation of mined lands.

Surface mine reclamation is regulated by Butte County primarily through three documents:

1. Butte County General Plan – contains language that provides general guidance on how and where mining should occur in the County.

2. Butte County Code, Chapter 13, Article II, Surface Mining and Reclamation – addresses mining reclamation plans, financial assurances, reporting, inspections and violations.

Given the Operator’s vested rights to mine, this Section 3.0 only addresses requirements that specifically relate to the reclamation of mined lands, and not those requirements associated with regulation of the mining activities, including any associated environmental review or land use approvals.

3.1 Butte County General Plan

The County General Plan recognizes that sand and gravel mining plays a significant role in the County’s economy. Table ED‐1 of the Economic Development Element of the General Plan indicates that as of 2016 “natural resources, mining and construction” accounts for 4,700 jobs or approximately six percent of the total nonfarm workforce. An explicit goal of the General Plan, as described in the Conservation and Open Space Element, is to “protect economically viable mineral resources and related industries while avoiding land use conflicts and environmental impacts from mining activities.” (Id. at p. 10‐36).

The General Plan contains the following policies that are applicable to the reclamation of mined lands:

W‐P1.2 The County shall cooperate with State and local agencies in efforts to identify and eliminate or minimize all sources of existing and potential point and non‐point

Pentz Pit Mine Reclamation Plan 29 January 2021

sources of pollution to ground and surface waters, including leaking fuel tanks, discharges from storm drains, auto dismantling, dump sites, sanitary waste systems, parking lots, roadways and logging and mining operations.

W‐P1.7 Agriculture, logging, mining, recreational vehicle use and other open space uses shall follow best management practices to minimize erosion and protect water resources.

As described in Section 2.6.1, above, surface and groundwater will continue to be protected from siltation and pollutants as required by the Federal Clean Water Act, the California Porter‐Cologne Water Quality Control Act, County ordinances, RWQCB and the State Water Resources Control Board. The Operator will comply with NPDES Industrial Storm Water General Permit requirements, including implementation of a SWPPP with BMPs to control erosion, sedimentation, and pollution. As required, the Operator will also implement a SPCC Plan and Hazardous Materials Business Plan pursuant to 40 CFR Part 112 and 19 CCR Section 2729, respectively. As such, this implementation of this Plan will be consistent with policies W‐P1.2 and W‐P1.7.

COS‐P12.4 Prior to approval of any new or expanded mining operation, the applicant shall demonstrate that the operation will not create significant nuisances, hazards or adverse environmental effects.

Approval of this Plan does not constitute approval of any new or expanded mining operation. As described in Section 1.4, above, this Plan has been developed to provide an environmentally superior update to the original RP 78‐99 and to clearly delineate existing Mine boundaries, encompasses within the Mine boundary all existing disturbances that were not originally approved under RP 78‐99, apply current reclamation standards pursuant to SMARA, identify the locations of temporary ephemeral stream crossings in the Ravine, and lay the necessary ground work for obtaining subsequent regulatory agency authorizations for future stream crossings and restoration of the Ravine.

NorCal proposes no increase in production levels, no changes in the existing methods of mining, and no new increase in areas approved for mining beyond those disturbances that have already occurred. Reclamation activity would not result in new significant environmental effects or a substantial increase in the severity of previously identified environmental effects. Instead, this Plan will ensure beneficial reclamation of areas that are not currently covered by the original RP 78‐99 (where no performance standards or financial assurances are currently in place).

COS‐P12.5 New mineral haul routes shall avoid landslides, highly erodible soils, residential areas and schools, when feasible.

No new mineral haul routes are planned.

Pentz Pit Mine Reclamation Plan 30 January 2021

COS‐P12.7 Mined property shall be left in a condition suitable for reuse in conformance with the General Plan land use designations and in accordance with the California Surface Mining and Reclamation Act (SMARA).

Section 2.0 of this Plan describes how the property will be left in a condition suitable for eth planned end use of gently rolling foothills in accordance with SMARA. The General Plan land use designation for the site is agriculture and the planned end use will support future dryland grazing consistent with this designation.

3.2 Butte County Surface Mining and Reclamation Code

The SMR Code recognizes that the extraction of minerals is essential to the continued economic well‐being of the County and to the needs of society, and that reclamation of mined lands is necessary to prevent or minimize adverse effects on the environment and to protect the public health and safety. (SMR Code, Section 13‐101). The purpose of the SMR Code is to create and maintain an effective and comprehensive surface mining and reclamation policy with regulation of surface mining operations so as to assure that:

(1) Adverse environmental effects are prevented or minimized and mined lands are reclaimed to a usable condition that is readily adaptable for alternative land use; (2) The production and conservation of minerals are encouraged, while giving consideration to values relating to recreation, watershed, wildlife, range and forage lands, and aesthetic enjoyment; (3) Residual hazards to the public health and safety are eliminated; (4) The reclamation of mined lands as provided in this article will provide for the protection and subsequent beneficial use of the mined and reclaimed land.

The SMR Code Section 13‐108 describes the standards for reclamation as well as reclamation plan contents. Each of these standards has been addressed in Section 2.0 of this Plan and are therefore not repeated here for the sake of brevity.

SUMMARY

Valley Sand and Rock (VSR, or Operator) operates the Pentz Pit Mine pursuant to vested mining rights and a Butte County Reclamation Plan. VSR’s operations facilitate reclamation of the site by removing non-native hydraulic mine tailings that have washed down from the historic Cherokee Mine (off-site) and deposited into portions of Sawmill Creek Ravine. VSR’s operations will aid in restoring the property to a more natural, native terrain over time. VSR is in the process of updating its current Reclamation Plan to cover existing and planned reclamation activities at the Mine.

On 15, 17 and 22 January 2020, a reconnaissance-level field survey of the Pentz Pit Mine (Study Area) was conducted for the purpose of identifying sensitive plant and wildlife species, sensitive habitats, and potential biological constraints. The surveyed area for this report incorporates approximately 232 acres located at the base of the Sierra Nevada foothills north of Highway 70 and east of Highway 191 in Butte County, California.

In summary, based on the reconnaissance survey, it was found that the site contains regulated waters of the United States and State of California, including a portion of Dry Creek, an unnamed intermittent blue line feature associated with Sawmill Ravine, and wetland features occurring along the boundaries of the gravel mining operations. It is assumed that these features would be regulated by the US Army Corps of Engineers (Corps), Regional Water Quality Control Board (RWQCB) and California Department of Fish & Wildlife (CDFW). As such, permit applications would have to be prepared and submitted to these agencies seeking authorization of any fill or impact associated with these potentially jurisdictional features. In addition, the site contains numerous quarry ponds and mining related depressions within the footprint of the active mining and processing operations.

Due to the presence of suitable habitat types and soil conditions within the Study Area, several special-status plant species have been identified as having the potential to occur on the Study Area. These include various species of Clarkia (Clarkia spp.), Red Bluff dwarf rush (Juncus leiospermus var. aharti) and Butte County checkerbloom (Sidalcea robusta).

Special-status wildlife species including conservancy fairy shrimp (Branchinecta conservatio), vernal pool fairy shrimp (Branchinecta lynchi), vernal pool tadpole shrimp (Lepidurus packardi), California linderiella (Linderiella californica), foothill yellow-legged frog (Rana boylii) and northwestern pond turtle (Actinemys marmorata) have the potential to occur within the Study Area based on the presence of suitable habitat types evaluated in January 2020. The Study Area and adjacent lands also provide nesting and foraging habitat for a number of raptors including golden eagle (Aquila chrysaetos), bald eagle (Haliaeetus leucocephalus), and red-shouldered hawk (Buteo lineatus), which were observed during the January 2020 surveys.

1.0 INTRODUCTION

At the request of VSR, Biological Resources Services (BRS) conducted a biological resources analysis of the Study Area, which is located in Butte County, California. This biological resources analysis includes pertinent literature on relevant background information and habitat characteristics of the site including the California Natural Diversity Database (CNDDB 2020) and the California Native Plant Society’s (CNPS) Inventory of Rate and Endangered Vascular Plants of California, the United States Fish and Wildlife Service’s (USFWS) IPaC query and a review of information related to species of plants and animals that could potentially utilize the described habitats. A general field reconnaissance investigation of the Study Area was conducted on 15, 17 and 22 January 2020. This report documents the methods, results and conclusions for the reconnaissance-level surveys conducted for the Study Area.

2.0 LOCATION

The Study Area is located at the base of the Sierra Nevada foothills north of Highway 70 and east of Highway 191 in Butte County, California (USGS Cherokee 7.5 minute quadrangle). Attachment 1, Figure 1 depicts the regional location of the Study Area in Butte County. Figure 2 illustrates the vicinity of the Study Area in relationship to the city of Oroville and Oroville Dam and identifies the location of the Study Area on the USGS 7.5 Quadrangle Map for Cherokee. Figure 3 provides an aerial photograph of the Study Area.

From Sacramento, access to the Study Area is attained by taking Highway 99 north towards Chico, then take Highway 70 north towards Oroville. At the Highway 149/70 split, take Highway 70 and go northeast to the interchange with Wheelock Road and proceed north of Wheelock to the mine entrance on Slickens Road. Access to the Study Area is authorized by checking in at the on-site office of the Pentz Pit Mine.

3.0 STUDY AREA DESCRIPTION

The majority of the 232-acre Study Area is a sand and gravel mining operation consisting of historic and actively mined areas. Current operations are focused on reclamation involving the removal of sand tailings along Sawmill Ravine, which is an intermittent stream system associated with the greater Lower Butte watershed. These tailings have been deposited in the ravine as a result of discharges from the historic Cherokee mine located east of the project site. The middle and lower reaches of this stream contain large patches of willow riparian scrub, cottonwood riparian woodland and some emergent wetland habitats. Other portions of the Study Area consists of patches of grazed annual grassland, riparian forest associated with Dry Creek, foothill pine-interior live oak woodland, blue oak woodland, and chaparral, which are found primarily along the northern, far western and far eastern portions. A number of mining related depressions occur throughout the Study Area in areas that have been mined, along with historic and active settling ponds.

The elevation ranges from approximately 653 feet mean sea level (msl) at the far eastern corner of the Study Area to approximately 386 feet msl in the far southwestern corner of the Study Area. The topography of the site favors drainage from the Sierra Nevada foothills east towards the Sacramento Valley floor of the greater Central Valley. Structures occurring on the Study

Area include an office and maintenance trailer; developed lands consist of previously excavated areas, numerous old and active haul roads, aggregate stockpiles, mine tailings, and infrastructure associated with mining and processing (e.g., conveyors, hoppers, etc.).

The Study Area is bordered on all sides by open space consisting of rangeland, some residential parcels, and previously mined areas on lands outside of the parcel boundaries. Representative photographs of the Study Area can be viewed in Attachment 3.

4.0 REGULATORY SETTING

4.1 Federal Regulatory Setting

4.1.1 Plants and Wildlife

The federal Endangered Species Act (ESA) of 1973 (16 USC 1531 et seq., as amended) prohibits federal agencies from authorizing, permitting, or funding any action that would result in biological jeopardy to a plant or animal species listed as Threatened or Endangered under the Act. Listed species are taxa for which proposed and final rules have been published in the Federal Register (U.S. Fish and Wildlife Service [USFWS], 2006a and 2006b). If a proposed project may jeopardize listed species, Section 7 of the ESA requires consideration of those species through formal consultations with the USFWS. Federal Proposed species (USFWS, 2006c) are species for which a proposed listing as Threatened or Endangered under ESA has been published in the Federal Register. If a proposed project may jeopardize proposed species, Section 7 of the ESA affords consideration of those species through informal conferences with USFWS. The USFWS defines federal Candidate species as “those taxa for which we have on file sufficient information on biological vulnerability and threats to support issuance of a proposed rule to list, but issuance of the proposed rule is precluded by other higher priority listing actions” (USFWS, 2007c). Federal Candidate species are not afforded formal protection, although USFWS encourages other federal agencies to give consideration to Candidate species in environmental planning.

4.1.2 Wetlands/Waters

The federal government, acting through the U.S. Army Corps of Engineers (Corps) and the Environmental Protection Agency (EPA), has jurisdiction over all “waters of the United States” as authorized by §404 of the Clean Water Act (CWA) and §10 of the Rivers and Harbors Act of 1899 (33 CFR Parts 320-330). Projects that cause the discharge of dredged or fill material into waters of the United States require permitting by the Corps. Actions affecting small areas of jurisdictional waters of the United States may qualify for a Nationwide Permit (NWP), provided conditions of the permit are met, such as avoiding impacts to threatened or endangered species or to important cultural sites. Projects that affect larger areas or which do not meet the conditions of an NWP require an Individual Permit. The process for obtaining an Individual Permit requires a detailed alternatives analysis and development of a comprehensive mitigation and monitoring plan.

Waters of the United States are classified as wetlands, navigable waters, or other waters. Wetlands are transitional habitats between upland terrestrial areas and deeper aquatic habitats such as rivers and lakes. Under federal regulation, wetlands are defined as “those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal conditions do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (33 CFR Part 328.3[b]). Swamps, marshes, bogs, fens and estuaries are all defined as wetlands, as are seasonally saturated or inundated areas such as vernal pools, alkali wetlands, seeps, and springs. In addition, portions of the riparian habitat along a river or stream may be a wetland where the riparian vegetation is at or below the ordinary high water mark and thus also meets the wetland hydrology and hydric soil criteria.

Navigable waters include all waters subject to the ebb and flow of the tides, including the open ocean, tidal bays, and tidal sloughs. Navigable waters also include some large, non-tidal rivers and lakes, which are important for transportation in commerce. The jurisdictional limit over navigable waters extends laterally to the entire water surface and bed of the waterbody landward to the limits of the mean high tide line. For non-tidal rivers or lakes, which have been designated (by the Corps) to be navigable waters, the limit of jurisdiction along the shoreline is defined by the ordinary high water mark. Other waters refer to waters of the United States other than wetlands or navigable waters. Other waters include streams and ponds, which are generally open water bodies and are not vegetated. Other waters can be perennial or intermittent water bodies and waterways. The Corps regulates other waters to the outward limit of the ordinary high water mark. Streams should exhibit a defined channel, bed and banks to be delineated as other waters.

Areas not considered to be jurisdictional waters include non-tidal drainage and irrigation ditches excavated on dry land, artificially-irrigated areas, artificial lakes or ponds used for irrigation or stock watering, small artificial water bodies such as swimming pools, and water-filled depressions with no outlet for drainage (33 CFR, Part 328), as well as …water-filled depressions created in dry land incidental to mining or construction activity including pits excavated for obtaining fill, sand or gravel that fill with water [33 CFR §328.3(b)(4)(v)].

4.1.3 Migratory Bird Treaty Act

Raptors are migratory bird species protected by international treaty under the Migratory Bird Treaty Act (MBTA) of 1918 (16 U.S.C. 703-711). The MBTA makes it unlawful to take, possess, buy, sell, purchase, or barter any migratory bird listed in 50 C.F.R. Part 10, including feathers or other parts, nests, eggs, or products, except as allowed by implementing regulations (50 C.F.R. 21). Sections 3503, 3503.5, and 3800 of the California Department of Fish and Game Code prohibit the take, possession, or destruction of birds, their nests or eggs. Implementation of the take provisions requires that project-related disturbance at active nesting territories be reduced or eliminated during critical phases of the nesting cycle (varies by geographic area, but typically between (January) February 1 - August 15 (30), annually). Disturbance that causes nest abandonment and/or loss of reproductive effort (e.g., killing or abandonment of eggs or young) or the loss of habitat upon which the birds depend is considered "take" and is potentially punishable by fines and/or imprisonment. Such taking would also violate federal law protecting migratory birds (e.g., MBTA).

4.2 State Regulatory Setting

4.2.1 Plants and Wildlife

Project permitting and approval requires compliance with California Environmental Quality Act (CEQA), the 1984 California Endangered Species Act (CESA), and the 1977 Native Plant Protection Act (NPPA). The CESA and NPPA authorize the California Fish and Game Commission to designate Endangered, Threatened and Rare species and to regulate the taking of these species (§§2050-2098, Fish & Game Code). The California Code of Regulations (Title 14, §670.5) lists animal species considered Endangered or Threatened by the State.

The Natural Heritage Division of the California Department of Fish and Wildlife (CDFW) administers the state rare species program. The CDFW maintains lists of designated Endangered, Threatened, and Rare plant and animal species (CDFG, 2008a and 2008b). Listed species either were designated under the NPPA or designated by the Fish and Game Commission. In addition to recognizing three levels of endangerment, the CDFW can afford interim protection to candidate species while they are being reviewed by the Fish and Game Commission.

The CDFW also maintains a list of animal species of special concern (CDFG, 2006), most of which are species whose breeding populations in California may face extirpation. Although these species have no legal status, the CDFW recommends considering them during analysis of proposed project impacts to protect declining populations and avoid the need to list them as endangered in the future.

Under the provisions of §15380(d) of the CEQA Guidelines, the project lead agency and CDFW, in making a determination of significance, must treat non-listed plant and animal species as equivalent to listed species if such species satisfy the minimum biological criteria for listing. In general, the CDFW considers plant species on List 1A (Plants Presumed Extinct in California), List 1B (Plants Rare, Threatened, or Endangered in California and elsewhere), or List 2 (Plants Rare, Threatened, or Endangered in California, But More Common Elsewhere) of the California Native Plant Society's (CNPS) Inventory of Rare and Endangered Vascular Plants of California (Skinner and Pavlik 1994) as qualifying for legal protection under §15380(d). Species on CNPS List 3 or 4 may, but generally do not, qualify for protection under this provision.

Sensitive habitats include riparian corridors, wetlands, critical habitats for legally protected species and CDFW Species of Special Concern, areas of high biological diversity, areas providing important wildlife habitat, and unusual or regionally restricted habitat types. Habitat types considered sensitive include those listed on the California Natural Diversity Data Base’s (CNDDB) working list of “high priority” habitats (i.e., those habitats that are rare or endangered within the borders of California) (Holland 1986).

4.2.2 Wetlands/Waters

The Regional Water Quality Control Board (RWQCB) regulates activities in wetlands and other waters through §401 of the Clean Water Act. Section 401 requires a state water quality certification for projects subject to 404 regulation. Requirements of the certification include

5 mitigation for loss of wetland habitat. California Fish and Game Code §§1600-1607 require the CDFW be notified of any activity that could affect the bank or bed of any stream that has value to fish and wildlife. Upon notification, the CDFW has the discretion to execute a Lake and Streambed Alteration Agreement. The CDFW defines streams as follows:

“... a body of water that flows at least periodically...through a bed or channel having banks and supporting fish and other aquatic life. This includes watercourses having a subsurface flow that supports or has supported riparian vegetation.” (Stream Bed Alteration Program, California Department of Fish and Wildlife).

In practice, CDFW authority is extended to any “blue line” stream shown on a USGS topographic map, as well as unmapped channels with a definable bank and bed. Wetlands, as defined by the Corps, need not be present for CDFW to exert authority.

4.2.3 Butte County General Plan – Oak Woodland Mitigation Ordinance

The Oak Woodland Mitigation Ordinance of the Butte County General Plan states the following:

The Draft Oak Woodland Mitigation Ordinance (November 2017) has been prepared to address impacts from proposed development (referred to as discretionary projects in the draft Ordinance). The draft ordinance focuses on the oak woodland as a habitat type. The Ordinance proposes that more than 10% removal of oak woodland canopy area is considered a significant impact subject to replacement (Butte 2018).

Currently, the impacts of discretionary projects on oak woodlands are reviewed on a case-by- case basis. Adoption of an oak woodlands ordinance would assist in defining impact thresholds under CEQA, standardizing practices so applicants know what to expect from the project review process, provide guidance how to avoid or minimize impacts to oak woodlands and allow staff to process applications more efficiently. There are a number of Goals, Policies and Action items from General Plan 2030 that support an oak woodland ordinance. Staff has also found that one option for mitigation of impacts to oak woodlands, payment to the Oak Woodlands Conservation Fund cannot currently be fulfilled by an applicant. The State will not accept payment unless the local jurisdiction has adopted a fee. The Ordinance as drafted is applicable only to discretionary projects – those that can be approved or denied and impact oak woodlands. Development Services has prepared this draft based on a consultant prepared version.

The Ordinance is drafted to be applicable to discretionary projects. Examples of discretionary projects include Subdivision Maps, Parcel Maps, Use Permits, and Minor Use Permits. These are applications that are subject to a public hearing and may be approved, denied or modified. Because they are discretionary, such applications are commonly subject to review under the California Environmental Quality Act (CEQA).

The following items are changes that were made between the July 2018 draft and November 2017 draft. Three of the main changes are as follows:

 The new DRAFT includes a change in the definition of Oak Woodland. This changes the applicability of the Ordinance. The definition no longer requires oaks to be 10% of

6

the tree canopy in order for the project to be subject to the Ordinance. This simplifies this portion of the draft ordinance and expands the applicability of the ordinance. This is a significant change from the previous draft.

 The new DRAFT sets a cap for the removal of oak woodlands by requiring that 30% remain (no more than 70% removal). This is borrowed from the Butte County Oak Woodland Management Plan. While the context of that plan is voluntary and is a recommendation regarding firewood removal, Butte County is proposing this same percentage as a cap for discretionary projects.

 The new DRAFT adds the Alternate Project Design and Review section. This section is to address projects that are not consistent with the ordinance. The ordinance is intended to serve as the steps for environmental review and mitigation. Projects that are consistent with the ordinance need not have additional CEQA review as it pertains to oak woodlands. This Alternate section recognizes that there may be projects that cannot comply with the ordinance standards. This section provides an answer for this situation – it requires that any project that is not consistent with the ordinance have its own project- specific analysis for oak woodlands.

5.0 METHODS OF ANALYSIS FOR GENERAL BIOLOGICAL RESOURCES

A special-status plant and wildlife species database search and review was conducted using the CNDDB and other sources. An additional search was conducted for special-status plants using California Native Plant Society Inventory On-Line (CNPS). Special-status species reports were accessed by searching the CNDDB database by the Cherokee, Paradise West, Paradisew East, Pulga, Hamlin Canyon, Berry Creek, Shippee, Oroville, and Oroville Dam 7.5-minute quadrangles, which surround the Study Area, and by examining those species that have been identified in the vicinity of the Study Area. The CNDDB report was used to focus special-status species analysis of the site prior to the reconnaissance surveys.

A BRS biologist (with expertise in botany and wetlands ecology) conducted a reconnaissance- level survey of the Study Area on 15, 17 and 22 January 2020. Existing conditions, observed plants and wildlife, adjacent land use, soils, wetland and “other waters” features and potential biological resource constraints were recorded during the visit. Plant and wildlife species observed within and adjacent to the Study Area during the reconnaissance survey are included in Attachment 2, Tables 1 and 2.

The objectives of the field surveys were to determine the potential presence or absence of special-status species habitat listed in the CNDDB database (CNDDB 2020) and to identify any wetland areas that could be potentially regulated by the Corps (Section 404) or state (Section 401). In addition, the BRS botanist/biologist looked for other potential sensitive species or habitats, which may not have been obvious from background database reports or research. Surveys conducted after the growing season or conducted outside of the specific flowering period for a special-status plant cannot conclusively determine the presence or absence of such plant species; therefore, site conditions and habitat type were used to determine potential for

7 occurrence. When suitable habitat was observed to support a special-status plant or animal species it was noted in the discussion for that particular species. Regulatory agencies evaluate the possibility of occurrence based on habitats observed on-site and the degree of connectivity with other special-status animal habitats in the vicinity of the Study Area. These factors are discussed in each special-status plant or animal section. Potential for occurrence of each special- status or protected plant and animal species was evaluated using the following criteria.

 Present: The species has been recorded by CNDDB or other literature as occurring on the Study Area and/or was observed on the Study Area during the reconnaissance survey or protocol surveys.  May Occur: The species has been recorded by CNDDB or other literature as occurring within five miles of the Study Area, and/or was observed within five miles of the Study Area, and/or suitable habitat for the species is present on the Study Area or its immediate vicinity.  Not Likely to Occur: The species occurs within five miles of the Study Area but only marginally suitable habitat conditions are present. The Study Area is likely to be used only as incidental foraging habitat or as an occasional migratory corridor.  Presumed Absent: The species will not occur on the Study Area due to the absence of suitable habitat conditions. Alternatively if directed or protocol-level surveys were done during the proper occurrence period and the species was not found it will be presumed absent.

Sources consulted for agency status information include USFWS (2008a, 2008b) and IPaC query and letter (Attachment 4) for federally listed species and CDFG (2008a) for State of California listed species. Based on information from the above sources, BRS developed a target list of special-status plants and animals with the potential to occur within or in the vicinity of the Study Area (Attachment 2, Table 3).

5.1 Soils Evaluation

The soils present within a Study Area may determine if habitat on the site is suitable for certain special-status plants and animals. The host plants of some special-status invertebrates may also require specific soil conditions. In the absence of suitable soil conditions, special-status plants or animals requiring those conditions would be presumed absent. Information regarding soil characteristics for the Study Area was obtained by viewing the Natural Resources Conservation Service (NRCS) Web Soil Survey report for the Study Area (NRCS 2020).

5.2 Plant Survey Methods

The purposes of the botanical surveys were (1) To characterize the habitat types (plant communities) of the study area; (2) to determine whether any suitable habitat for any special- status plant species, occurs within the study area; and (3) to determine whether any sensitive habitat types (wetlands) occur within the study area, (4) and to determine if any special-status plant species occur in the Study Area area. Site conditions and plant habitat surveys are important tools in determining the potential occurrence of plants not recorded during surveys

8

(e.g., special-status plants) because presence cannot conclusively be determined if field surveys are conducted after the growing season or conducted outside a specific flowering period.

5.2.1 Review of Literature and Data Sources

The BRS botanist conducted a query of literature and special-status species databases in order to identify special-status plant species and sensitive habitat types with potential to occur in the Study Area. Sources reviewed include: CNDDB occurrence records (CNDDB 2020) and CNPS Inventory (Skinner and Pavlik 1994) for the Cherokee, Paradise West, Paradise East, Pulga, Hamlin Canyon, Berry Creek, Shippee, Oroville, and Oroville Dam USGS 7.5 quadrangles; and standard flora (The Jepson Manual, 2nd Edition (TJM2, 2012). From the above sources, a list of special-status plant species with potential to occur in the Study Area vicinity was developed (Attachment 2, Table 3).

5.2.2 Field Surveys

A BRS botanist conducted a reconnaissance-level survey to determine habitat types and the potential for special-status plants based on the observed habitat types on 15, 17 and 22 January 2020. All vascular plant species that were identifiable at the time of the survey were recorded and identified using keys and descriptions in TJM2. The habitat types occurring within the Study Area were characterized according to pre-established categories. In classifying the habitat types on the site, the generalized plant community classification schemes of A Manual of California Vegetation (Sawyer and Keeler-Wolf 1995) were consulted. The final classification and characterization of the habitat types of the study area were based on field observations.

5.3 Wildlife Survey Methods

The purposes of the wildlife surveys were to identify special-status wildlife species and/or potential special-status wildlife habitats within the Study Area.

5.3.1 Review of Literature and Data Sources

A query of literature and data sources was conducted in order to determine which special-status wildlife species had potential to occur in the vicinity of the Study Area. Current agency status information was obtained from USFWS (2008b) and IPaC report for species listed as Threatened or Endangered, as well as Proposed and Candidate species for listing, under the federal ESA; and from CDFW (2008a, 2008b) for species listed as Threatened or Endangered by the state of California under the CESA, or listed as “species of special concern” by CDFW. From the above sources, a list of special-status wildlife species with potential to occur in the Study Area vicinity was developed (Attachment 2, Table 3).

5.3.2 Field Surveys

General Wildlife Survey – A BRS biologist conducted surveys of species habitat within the entire Study Area, including visible portions of the adjacent properties during the January 2020 surveys. The purpose of the habitat surveys was to evaluate wildlife habitats and the potential for any protected species to occur on or adjacent to the Study Area.

9

Reconnaissance-Level Raptor Survey – A preliminary reconnaissance-level raptor survey was conducted in the Study Area during the three-day January 2020 site assessment. This survey was conducted with the use of binoculars and notes were taken for each species occurrence. Additionally, utility poles and perch sites in the vicinity of the Study Area were observed. All raptor activity within and adjacent to the area was recorded during the reconnaissance-level observation period.

6.0 RESULTS FOR GENERAL BIOLOGICAL RESOURCES

The search and review of the CNDDB database reports revealed the occurrence of special-status plant and wildlife species that occur in chaparral, cismontane woodland, valley and foothill grassland, riparian scrub, meadows and seeps, and freshwater marshes and swamp habitats (CNDDB 2020). The CNDDB database and background data were reviewed for the Cherokee, Paradise West, Paradise East, Pulga, Hamlin Canyon, Berry Creek, Shippee, Oroville, and Oroville Dam 7.5 minute quadrangles. A map showing the locations of special-status plants and animals reported in the vicinity of the Study Area is included as Attachment 1, Figures 4 and 5, respectively. Those animals listed in Attachment 2, Table 1 were reviewed for their potential to occur on the Study Area based on general habitat types. Some of the plant and animal species identified by the CNDDB in the quadrangles require a specific microhabitat that was found not to occur within the Study Area. Based on our analysis of existing vegetative assemblages occurring within the Study Area, a map showing the extent of existing plant communities (along with their potential to provide habitat functions and values for local wildlife populations), is provided in Attachment 1, Figure 6.

6.1 Soil Evaluation Results

The USDA Natural Resources Conservation Service (formerly the Soil Conservation Service) mapped eight soil types within the Study Area: Typic Xerofluvents, Ultic Haploxeralfs, Palexerults (2 mapped soil units), Flagcanyon-Wickscorner, and Oroshore-Mounthope-Dunstone (3 mapped soil units) (NRCS 2020). The majority of the Study Area – where past and current mining occurs – are Typic Xerofluvents, sandy-skeletal, 0 to 2 percent slopes. A small inclusion of UlticHaploxeralfs, sandstone, low elevation, complex, 2 to 5 percent slopes occurs along the extreme eastern boundary in association with Dry Creek. Of the two mapped soil units of Palexerults, Palexerults with 15 to 30 percent slopes occurs along the extreme southern boundary in the eastern portion of the Study Area, while Palexerults with 2 to 15 percent slopes occurs along the far northeastern and east-central portions of the Study Area. A small inclusion of Flagcanyon-Wickscorner, 2 to 5 percent slopes occurs along the east-central boundary, while three soil units of Oroshore-Mounthope-Dunstone 15 to 30 percent slopes - occur as small inclusions along the far eastern portion of the Study Area. A detailed map of these soils for the Study Area can be found in Attachment 1, Figure 7. The following provides a brief description of the eight mapped soil units:

6.2 Plant Survey Results

6.2.1 Floristic Inventory and Habitat Characterization

In classifying the habitat types in the Study Area area, generalized plant community classification schemes were used (Sawyer and Keeler-Wolf 1995). The final classification and characterization of the habitat types of the Study Area were based on field observations.

The Study Area supports 13 habitat types that consist of annual grassland, chaparral, foothill pine-interior live oak woodland, blue oak woodland, valley oak-sycamore riparian forest, cottonwood riparian woodland, willow riparian scrub, settling ponds, fresh water pond, quarry pond, mining related depression, ruderal and developed. Each habitat is described in further detail below. A description of the plant species present within each habitat type is provided below. Dominant plant species are noted. A complete list of plant species observed on the Study Area can be found in Attachment 2, Table 1.

6.2.1.2 Annual Grassland

A relatively undisturbed example of this habitat occurs along the northeastern portion of the Study Area where a new haul road will be developed; remaining areas are primarily found in the eastern half where it occurs in relatively open portions in the herbaceous understory of mixed foothill pine-interior live oak and blue oak woodland. Dominant species within these areas appear to be largely comprised of non-native annual grasses and broad-leaved plants. Non-native plants identifiable at this time (either as seedlings or fragmented stems from the previous season’s growth) included bromes (Bromus diandrus and B. madritensis), fescue (Festuca (myuros)), and medusahead grass (Elymus caput-medusae); non-native broad-leaved plants included longbeak stork’s bill (Erodium botrys), dove’s-foot geranium (Geranium molle), vetch (Vicia spp.), rose clover (Trifolium hirtum), yellow-star thistle (Centaurea solstitialis), and short- pod mustard (Hirschfeldia incana).

While infrequent, native forbs (i.e., wildflowers) that were observed included tarweed (Holocarpha sp.), fiddleneck (Amsinckia sp.), turkey mullein (Croton setiger), navarretia (Navarretia sp.), Clarkia (Clarkia sp.), clover (Trifolium sp.) and species of the Themidaceae family (e.g., Brodiaea, Dichlostema, etc.).

6.2.1.3 Chaparral

This habitat type occurs on sandy-gravelly terraces and bluffs above Sawmill Ravine in the far eastern portion of the Study Area. The dominant vegetative cover consists of various species of widely scattered manzanita, including common manzanita (Arctostaphylos manzanita ssp. manzanita), greenleaf manzanita (Arctostaphylos patula) and whiteleaf manzanita (Arctostaphylos viscida ssp. viscida). The gravelly-sandy substrates supported a sparse herbaceous understory that included vetch (Vicia asp.), Spanish clover (Acmispon americanus var. americanus), California fuschia (Epilobium (canum), lupine (Lupinus spp.) and clarkia

22

(Clarkia spp.). Shrubs included coyote brush (Baccharis pilularis), poison oak (Toxicodendron diversilobum), ceanothus (Ceanothus sp.) and toyon (Hereomeles arbutifolia), which often delineated the ecotone between chaparral and foothill pine-interior live oak and blue oak woodland habitats.

6.2.1.4 Mixed Foothill Pine-Interior Live Oak Woodland

Mixed foothill pine-interior live oak woodland occurs primarily along the north-central and eastern portions of the Study Area; this habitat type frequently intergrades with chaparral in the eastern portion and occurs as fragmented stands on old elevated mine tailings throughout the previously mined portions of the Study Area. Dominant trees were foothill pine (Pinus sabiniana) and interior live oak (Quercus wislizeni var. wislizeni). Shrubs in the understory consisted of manzanita, toyon, poison oak, coyote brush and in some areas, French broom (Genista monspessulana). The herbaceous understory consisted of miner’s lettuce (Claytonia perfoliata), field-hedge parsley (Torilis (arvensis)), hedge-hog dogtail (Cynosurus echinatus), deer grass (Muhlenbergia rigens), rip-gut brome (Bromus diandrus), sedge (Carex sp.), California polypody (Polypodium californicum), goldback fern (Pentagramma triangularis), bird’s-foot fern (Pellaea mucronata var. mucronata) and blue dicks (Dichelostemma capitatum ssp. capitatum).

6.2.1.5 Blue Oak Woodland

Blue Oak Woodland occurs primarily along the southern boundary at the far eastern portion of the Study Area and intergrades with adjacent chaparral and mixed foothill pine-interior live oak woodland habitats. Canopy dominance is exhibited by blue oak (Quercus douglasii); sub- dominant trees include interior live oak and foothill pine. The shrub layer in this habitat type was somewhat sparse, with toyon, poison oak and some manzanita present. The herbaceous groundlayer vegetation association was similar to mixed foothill pine-interior live oak, with a higher percentage of various species of annual grasses and forbs often found in annual grassland habitats, including blue dicks, small-flowered melicgrass (Melica imperfecta), triteleia (Triteleia sp.), shooting stars (Primula sp.) and narrow leaf soap plant (Chlorogalum angustifolium).

6.2.1.6 Valley Oak-Sycamore Riparian Forest

A very small inclusion of this habitat type occurs along Dry Creek along the far western boundary of the Study Area. Valley oak (Quercus lobata) and western sycamore (Platanus racemosa) were the co-dominant woody tree species in this habitat type. Sub-dominant trees included Fremont’s cottonwood (Populus fremontii ssp. fremontii) and arroyo willow (Salix lasiolepis). The well-developed shrub and lliana layers consisted of poison oak, Himalayan blackberry (Rubus armeniacus), Dutchman’s pipe (Aristolochia californica) and California wild grape (Vitis californica), with infestations of French broom in some areas. Patches of stinging nettle (Urtica dioica ssp. holosericea) were common along the banks of Dry Creek.

23

6.2.1.7 Cottonwood Riparian Woodland

This habitat type borders the left and right banks of the Sawmill Ravine stream feature in the north-central portion of the Study Area. While the dominant tree species is Fremont’s cottonwood, the age and size class of the existing stand is of fairly recent origin and thus lacks a well-structured woody canopy with shrub and herbaceous layer associates. While coyote brush was present, this habitat type has a very severe infestation of Spanish broom (Spartium junceum) in the understory.

6.2.1.8 Willow Riparian Scrub

Two large wetland areas consisting of willow riparian scrub habitat occur in the Study Area; this habitat type intergrades with emergent wetlands and mining related depressions found in other portions of the Study Area. The dominant tree species is sandbar willow (Salix exigua); sub- dominant woody species include arroyo willow, red willow (Salix laevigata), and white alder (Alnus rhombifolia). Poison oak, Himalayan blackberry and mulefat (Baccharis salicifolia) are the primary shrub species present. The herbaceous understory consists of a number of hydrophytic graminoids including various species of sedge (Carex spp.) rush (Juncus spp.), miniature tule (Isolepis cernua) and tall flatsedge (Cyperus eragrostis); other species include giant horsetail (Equisetum telmateia ssp. braunii).

6.2.1.9 Industrial Ponds and Mining Related Depressions

The Study Area includes settling ponds, fresh water pond, quarry pond, and mining related depressions that are associated with mining and reclamation operations at the site.

As stated in 33 CFR §328.3, water-filled depressions created in dry land incidental to mining or construction activity including pits excavated for obtaining fill, sand, or gravel that fill with water may not meet the definition of waters of the U.S.

Settling Ponds Two types of settling ponds are present within the Study Area: Active and historic. Active settling ponds are located in close proximity to the operational batch plant where mined aggregate materials are processed and stockpiled. The largest active settling pond intercepts discharges directly from the mainstem channel of Sawmill Ravine via a spillway where turbid waters are allowed to settle before being discharged into the far-western complex of old mine tailings and braided channels that eventually discharge over a second spillway adjacent to Dry Creek. Very little emergent vegetation was observed growing along the edges of these active settlings ponds; tall flatsedge and cattail were the most common species present.

Historic settling ponds were located primarily north and west of the active settling ponds in close proximity to Dry Creek and could be classified as largely dominated by emergent marsh habitat with woody co-dominance exhibited by arroyo willow, red willow and Fremont’s cottonwood. Various species of rush (Juncus spp.), dock (Rumex spp.), cattail, California tule, Himalayan blackberry and willow weed (Persicaria (lapathifolia)) were commonly observed.

24

The settling ponds are presumed to be non-jurisdictional pursuant to 33 CFR §328.3.

Fresh Water Pond A single, fresh water pond feature occurs on the northeast side of the aggregate processing plant. The fresh water pond is presumed to be non-jurisdictional pursuant to 33 CFR §328.3.

Quarry Pond A single, deep pond feature (i.e., greater than six (6.6) feet in depth) occurs just south of the active haul road and is labeled QP (i.e., quarry pond). The quarry pond is presumed to be non- jurisdictional pursuant to 33 CFR §328.3.

Mining Related Depressions Mining-related depressions occur throughout portions of the Study Area that have been mined in the past. Most of these features have vegetative assemblages similar to those found in seasonal and emergent wetlands. However, they represent a complex of active industrial mining ponds that may not meet the definition of waters of the U.S. Some of these features intercept and pond direct precipitation and sheetflow runoff during the rainy season. Observed robust emergent monocots were cattail (Typha sp.) and California tule (Schoenoplectus californicus). Graminoid species include tall flatsedge, miniature tule, common spike rush (Eleocharis macrostachya), spreading rush (Juncus effusus), tapertip rush (Juncus acuminatus) iris-leaved rush (Juncus xiphioides), broomsedge bluestem (Andropogon virginicus var. virginicus), annual beardgrass (Polypogon monspeliensis), and perennial ryegrass (Festuca perenne). Other hydrophytic associates include western goldenrod (Euthamia occidentalis), willow weed (Persicaria (lapathifolia)), cudweed (Pseudognaphalium beneolens) and pennyroyal (Mentha pulegium). Where present, woody tree and shrub species include sandbar willow, arroyo willow, Fremont’s cottonwood and mulefat. While cottonwood seedlings may be present, larger saplings and trees were mostly uncommon. The mining related depressions are presumed to be non-jurisdictional pursuant to 33 CFR §328.3.

6.2.1.10 Ruderal

Ruderal (i.e., disturbance) habitats are associated with areas that have undergone and/or continue to undergo some type of disturbance regime to the existing vegetative cover. Disturbance activities may be natural (e.g., flooding, fire, landslides) or anthropogenic (e.g., discing, mowing, spraying).

Ruderal assemblages were most commonly observed in the former quarry portions of the Study Area where the historic soil profile has been altered or eliminated by past mining activities (i.e., those areas where sand and gravel substrates lack substantial vegetative cover such as old quarry floors, old mine tailings or along unmined edges of relict stands of foothill pine-interior live oak woodland areas along the far western and southern portions of the Study Area).

Dominant non-native annual grasses and broad-leaved plants observed included bromes, fescue, medusahead grass, longbeak storks bill, vetch, rose clover, yellow-star thistle short-pod mustard and stinkweek (Dittrichia graveolens).

25

6.2.1.11 Developed

Developed areas found throughout the Study Area had little to no standing vegetative cover and included the active aggregate batch/processing area, active stockpiles, maintenance and trailer areas, sand extraction (as part of mining and reclamation) in the eastern portion and active haul roads.

6.2.2 Special-Status Plant Species

Special-status plant species include species listed as Rare, Threatened, or Endangered by the USFWS (2008a) or by the State of California (CDFG 2008a). Federal Proposed and Candidate species (USFWS, 2008b) are also special-status species. Special-status species also include species listed on List 1A, List 1B, or List 2 of the CNPS Inventory (Skinner and Pavlik, 1994; CNPS 2008). All species in the above categories fall under state regulatory authority under the provisions of CEQA, and may also fall under federal regulatory authority. Considered special- status species are species included on List 3 (Plants About Which We Need More Information—A Review List) or List 4 (Plants of Limited Distribution—A Watch List) of the CNPS Inventory. These species are considered to be of lower sensitivity and generally do not fall under specific state or federal regulatory authority. Specific mitigation considerations are not generally required for List 3 and List 4 species and are therefore no longer addressed in this report.

Attachment 2, Table 1 includes a list of special-status plants with the potential to occur within or in the immediate vicinity of the Study Area based on a review of the USGS 7.5 minute quadrangles for Cherokee, Paradise West, Paradise East, Pulga, Hamlin Canyon, Berry Creek, Shippee, Oroville, and Oroville Dam. The special-status plant species identified by the CNDDB as potentially occurring on the Study Area are known to occur within specific habitat types. The specific habitats or “micro-climate” necessary for some of the plant species to occur are not found within the boundaries of the subject Study Area. The habitats necessary for the CNDDB reported plant species consist of valley and foothill grassland, meadows, seeps, cismontane woodland, chaparral, freshwater marshes and swamps, riparian scrub; preferred soil substrates include sandy, rocky, and granitic.

6.3 Wildlife Survey Results

6.3.1 General Wildlife Species and Habitats

A complete list of wildlife species observed on the Study Area can be found in Attachment 2, Table 2. Wildlife species commonly occurring within habitat types present on the Study Area are discussed below:

Mammal species observed (or their sign; e.g., scat, tracks, burrows) during the January 2020 surveys included bobcat (Lynx rufus; tracks), coyote (Canis latrans; tracks and scat), North American beaver (Castor canadensis; active dam within the far western willow riparian scrub wetland complex), black-tailed jackrabbit (Lepus californicus), western grey squirrel (Sciurus griseus) and black-tailed deer (Odocoileus hemionus).

Despite the absence of continuous vegetative cover throughout large portions of the Study Area due to past mining activities, wildlife species observed during the January 2020 surveys include raptors such as red-shouldered hawk (Buteo lineatus), golden eagle (Aquila chrysaetos), bald eagle (Haliaeetus leucocephalus) and great-horned owl (Bubo virginianus), which were observed over the site. Aerial foragers such as American crow (Corvus brachyrhynchos) and turkey vulture (Cathartes aura) were also observed over the Study Area. The various habitats present within the Study Area provide ample foraging opportunities for the omnivorous Woodhouse’s scrub-jay (Aphelocoma woodhouseii), which was also observed. Acorns from the various species of oaks present within the Study Area provide ample foraging opportunities for the acorn woodpecker (Melanerpes formicivorus), which was observed (along with old branch and trunk acorn caches) during the January 2020 surveys.

Passerines such as white-crowned sparrow (Zonotrichia leucophrys), black phoebe (Sayornis nigricans), spotted towhee (Pipilo maculatus), dark-eyed junco (Junco hyemalis), mourning dove (Zenaida macroura), western bluebird (Sialia mexicanus), yellow-rumped warbler (Dendroica coronata), and a species of vireo (Vireo sp.) were also observed within the Study Area. Wild turkey (Meleagris gallopavo) were also observed in the far western portion of the Study Area. Wilson’s snipe (Gallinago delicata) was flushed from one of the emergent marsh habitats during the January 2020 surveys; killdeer (Charadrius vociferus) and other shorebirds would be expected to utilize the settling ponds, emergent and seasonal wetlands and open quarry areas for foraging and nesting opportunities.

30

Due to the abundance of woodland and open grassland habitats in the vicinity of the Study Area, it is expected that other raptors such as red-tailed hawk (Buteo jamaicensis), Cooper’s hawk (Accipiter cooperii), sharp-shinned hawk (Accipiter striatus) and American kestrel (Falco sparverius) may also likely occur within the Study Area.

While no reptiles were observed during the January 2020 surveys, reptiles such as the California kingsnake (Lampropeltis californiae), northern pacific rattlesnake (Crotalus oreganus oreganus), gopher snake (Pituophis melanoleucus) and Sierra gartersnake (Thamnophis couchii) could likely occur in the Study Area. The only amphibian observed during the January 2020 survey was a Pacific tree frog (Pseudacris regilla).

6.3.2 Special-Status Wildlife Species

Attachment 2, Table 3 includes a list of special-status wildlife species with potential to occur in the Study Area area. Special-status wildlife species include species listed as Rare, Threatened, or Endangered by the USFWS (2008b & 2008c), as well as those species covered by the MBTA, or those species given special protection by the State of California (CDFG, 2008b).

The search and review of the CNDDB database and USFWS IPaC reports revealed the occurrence of special-status species could potentially occur in the annual grassland, chapparal, cismontane woodland, riparian woodland and forest, and seasonal wetland habitats supported by the Study Area (Attachment 1, Figure 5). In addition, some state-protected raptors could forage on the Study Area. Attachment 2, Table 2 provides a summary of the species, their status, and habitat requirements. Some species do not have any special protection, but are included in the CNDDB due to their local rarity. For the analysis of the site, the following specific discussions on the special-status wildlife included the following species:

INVERTEBRATES

Vernal Pool Fairy Shrimp (Branchinecta lynchi). Federally Threatened

Vernal pool fairy shrimp were listed as threatened by the USFWS on September 19, 1994. Critical habitat for vernal pool fairy shrimp was originally designated on August 6, 2003. The designation was revised on August 11, 2005 and species by unit designations were published on February 10, 2006 (USFWS 2007a).

The vernal pool fairy shrimp occupies a variety of different vernal pool habitats, from small, clear, sandstone rock pools to large, turbid, alkaline, grassland valley floor pools. This species tends to occur in smaller pools and is most frequently found in pools less than 0.05 acre in size. Vernal pool fairy shrimp typically occur in grass or mud bottomed swales, or basalt flow depression pools in unplowed grasslands (USFWS 2007a).

Female fairy shrimp carry their eggs in a ventral brood sac. The eggs either are dropped to the pool bottom or remain in the brood sac until the mother dies and sinks. When the pool dries out, so do the eggs. Resting fairy shrimp eggs are referred to as cysts. These cysts remain in the dry pool bed until rains and other environmental stimuli cause them to hatch (USFWS 2007a). Cysts

31

are capable of withstanding heat, cold and prolonged desiccation. The cyst bank in the soil may contain cysts from several years of breeding. Mature adults have been observed in vernal pools three to four weeks after the pools had been filled.

There are CNDDB records of this species within a 5-mile radius of the Study Area. However, the Study Area does not occur within USFWS designated critical habitat for this species. The clear, somewhat deep mining related depressions in the mined quarry areas along the southern boundary could provide potentially suitable habitat to support this species. However, protocol- level surveys would have to conducted to determine presence/absence of this species within the Study Area.

Vernal Pool Tadpole Shrimp (Lepidurus packardi). Federally Endangered

Vernal pool tadpole shrimp were listed as threatened by the USFWS on September 19, 1994. Critical habitat for vernal pool tadpole shrimp was originally designated on August 6, 2003. The designation was revised on August 11, 2005 and species by unit designations were published on February 10, 2006 (USFWS 2007b).

Vernal pool tadpole shrimp occur in a wide range of vernal pool habitats across the Central Valley of California, from Shasta County to northwestern Tulare County. Isolated occurrences have also been reported in Alameda and Contra Costa Counties. Vernal pool tadpole shrimp distribution is highly fragmented (USFWS 2007b).

The vernal pool tadpole shrimp is a small crustacean in the family Triopsidae. Vernal pool tadpole shrimp adults reach a length of two inches. This animal inhabits vernal pools containing clear to highly turbid water that range in size. Vernal pool tadpole shrimp have been found in pools up to 89 acres in size (USFWS 2007b).

As with the other vernal pool branchiopods described above, vernal pool tadpole shrimp populations are reestablished from cysts that lie dormant in the dry pool sediments when pools refill. Mature adults have been observed in vernal pools three to four weeks after the pools had been filled.

There are CNDDB records of this species within a 5-mile radius of the Study Area. However, the Study Area does not occur within USFWS designated critical habitat for this species. The clear, somewhat deep mining related depressions in the mined quarry areas along the southern boundary could provide potentially suitable habitat to support this species. However, protocol- level surveys would have to conducted to determine presence/absence of this species within the Study Area.

California Linderiella (Linderiella occidentalis). Federal Species of Special Concern

Found in the same vernal pool habitats as the fairy shrimp, California linderiella occur in clear vernal pools and lakes. They are tolerant of a wide rage of conditions, withstanding turbid conditions and pH levels between 6.1 and 8.5. They are able to tolerate temperature conditions from 41 to 85 F. Like the fairy shrimp, eggs become encysted during dry conditions and hatch

32

when the vernal pools refill. Threats to this species include habitat loss, alteration of vernal pool hydrology, water contamination, off-road vehicle use and invasive non-native species.

While there are no CNDDB records for this species occurring within a 5-mile radius of the Study Area, the clear, somewhat deep mining related depressions throughout the mined areas in the southern portions of the Study Area may support this species. However, protocol-level surveys would have to conducted to determine presence/absence of this species within the Study Area.

Valley elderberry longhorn beetle (Desmocerus californicus dimorphus). Federally Threatened

The VELB was federally listed on August 8, 1980. Critical habitat was designated at the same time. A Recovery Plan for this species was released on June 28, 1984, but is now outdated. In February 2007, USFWS prepared a five-year review for this species, which recommends delisting of VELB (USFWS 2007c), and a delisting proposal has been recently released (USFWS 2012b).

VELB is limited to portions of the Central Valley, below 3,000 feet in elevation (USFWS 1999a). The range of the VELB extends throughout California’s Central Valley and associated foothills from about the 3,000-foot elevation contour on the east and the watershed of the Central Valley on the west. Portions of Shasta County are included in this range.

The VELB is dependent on its host plant, elderberry (Sambucus sp.), which is a common component of riparian corridors and adjacent upland areas in the Central Valley. There are four stages of this species life: egg, larva, pupa, and adult. Females deposit eggs on or adjacent to the host elderberry. Egg production varies between 16 and 180 eggs (USFWS 2007c). Eggs hatch within a few days of being deposited and larvae emerge. The larvae bore into the wood of the host plant and create a long feeding gallery in the pith of the elderberry stem. The larvae feed on the pith of the plant for one to two years. When a larva is ready to pupate, it chews an exit hole to the outside of the stem and then plugs it with frass. The larva then retreats into the feeding gallery and constructs a pupal chamber from wood and frass. The larvae metamorphose between December and April; the pupal stage lasts about a month. The adult remains in the chamber for several weeks after metamorphous, and then emerges from the chamber through the exit hole. Most records for adults occur from late-April to mid-May (USFWS 2007c). Adults feed on elderberry leaves and mate within the elderberry canopy.

VELB occurs most frequently and is most abundant in significant riparian zones that are well developed. Within significant riparian zones, VELB primarily occurs within the riparian corridor but can occur infrequently in non-riparian scrub habitats adjacent to the riparian corridor. VELB exit holes are usually found on stems or branches of one inch in diameter or greater (Barr 1991, Collinge et al. 2001 in Talley et al. 2006) and are found infrequently in smaller stems (1.3-2 cm) (Halstead and Oldham 1990, Talley 2005 in Talley et al. 2006). In the northern portion of the VELB’s range, exit holes are most frequently observed in stems and branches 5 to 10 cm in diameter (Barr 1991, Collinge et al. 2001 in Talley et al. 2006).

33

Only two elderberry shrubs were observed within the Study Area. Both were carefully examined for the presence of potential VELB exit holes; no exit holes were found.

AMPHIBIANS

Foothill Yellow-Legged Frog (Rana boylii). Federal Species of Special Concern, California Species of Special Concern

The foothill yellow-legged frog is a medium-sized frog with a slim waist, long legs, and webbing on the hind feet. The skin is grainy rather than smooth and ridges on the sides (dorsolateral folds) are not distinct. This species is strongly associated with shallow, low-gradient channels with riffles that have unconsolidated coarse substrates; however, the range of aquatic habitat in which they have been found in is diverse; frogs have been observed in permanent and intermittent streams with low to relatively high gradients, alluvial and bedrock channels (Leidy et al. 2009), stream-associated backwaters and isolated pools (Hayes and Jennings 1988), and slow-moving rivers with mud-substrates. They occupy habitat ranging from sea level to approximately 5,800 feet. Suitable habitat may be seasonal refugia (non-breeding habitat), breeding and rearing sites, or movement corridors.

The relatively high-velocity flows observed within the channel of the stream system associated with Sawmill Ravine may preclude the presence of this species within the Study Area. However, lower velocity tributaries into this system, as well as lower down the valley floor towards, and in, Dry Creek, may provide potentially suitable habitat for this species.

There are CNDDB records for this species within a 5-mile radius of the Study Area. However, protocol-level surveys would have to conducted to determine presence/absence of this species within the Study Area. No yellow-legged frogs were observed during the January 2020 field surveys.

California Red-Legged Frog (Rana draytonii). Federally Threatened, California Species of Special Concern

This medium-sized frog has a slim waist, smooth skin and webbing on the hind feet. Ridges (i.e., dorsolateral folds) on the upper sides are prominent. When extended, the legs are relatively long, and the eyes are outward oriented. The California red-legged frog spends most of its life in and near sheltered backwaters of ponds, marshes, springs, streams, and reservoirs. Deep pools with dense stands of overhanging willows and an intermixed fringe of cattails are considered optimal habitat. Eggs, larvae, metamorphs, and adults also have been found in ephemeral creeks and drainages and in ponds that do not have riparian vegetation.

While the absence of deep pools with suitable emergent and/or woody riparian habitat likely precludes this species from the intermittent stream associated with Sawmill Ravine, the mosaic of mining related depressions and historic settling ponds in the far western portion of the Study Area may provide suitable future breeding habitat for this species. However, possible high turbidity levels in the water column associated with mining operation runoff and the absence of burrow complexes of fossorial mammals (e.g., California ground squirrels) in close proximity to

34

the Study Area for upland dispersal habitat after the breeding season likely precludes the presence of this species. No red-legged frogs were observed during the January 2020 field surveys.

REPTILES

Northwestern Pond Turtle (Actinemys marmorata). California Species of Special Concern

The northwestern pond turtle is a thoroughly aquatic turtle that may be found in marshes, ponds, streams and irrigation ditches where aquatic vegetation is present. The turtles, which range from nine to ten inches in size, require basking sites and suitable upland habitat for egg laying. Suitable breeding upland habitats may consist of sandy banks or grassy open fields. The western pond turtle has a dark brown to olive-colored carapace with hexagonal scales that lack prominent markings.

Nesting and incubation occur from April to September, with a peak time for mating and egg laying occurring from March to May. Most nests are with 90 meters (300 feet) of water. Activity slows from November to February. During the winter when water and air temperatures cool, usually from September to March, the turtles begin to hibernate. During hibernation, turtles either bury themselves in the mud at the bottom of ponds or will bury themselves on land in duff (top layer of decomposing vegetation and soil). Some turtles travel more than a half mile to over-winter on land, though many select the nearest wooded or shrubby area they can bury in. Turtles then emerge from hibernation in the spring to start the yearly cycle again.

While there are no CNDDB records for this species within a 5-mile radius of the Study Area, the mosaic of slow-moving mine tailing streams and historic settling ponds in the willow riparian scrub habitat located in the far western portion could provide potentially suitable habitat for this species. No pond turtles were observed during the January 2020 field surveys.

Giant Garter Snake (Thamnophis gigas). Federally and State Threatened

Giant garter snake (GGS) was listed by USFWS as threatened on October 20, 1993. A Draft Recovery Plan was drafted for the species on July 2, 1999 and a five year review was conducted in September 2006 (USFWS 2009b). No change in listing status was recommended in the five year review and no critical habitat has been proposed for this species.

GGS occurs in wetland, rice field, and slough habitat in the Central Valley of California. They primarily occur in the Sacramento Valley; however, recently snakes have been detected in the San Joaquin Valley (USFWS 2009b).

The GGS is endemic to Central Valley wetlands, inhabits natural and manmade habitats, and feeds on small fish and amphibians. The snake requires a mix of habitat components, such as adequate water during the early-spring through late-fall active period; emergent wetland vegetation for escape and feeding cover; grassy banks and openings for resting or basking cover; and uplands to escape flooding. It moves to small animal burrows and soil crevices during its winter dormancy. Giant garter snake use of rice fields includes hunting for prey in the flooded checks and basking on the check dams and surrounding upland habitats during the summer

35

(USFWS 1999b). The snakes move off of the fields in late summer/fall once the water is drained from the fields, but they may still find prey concentrated in irrigation ditches (USFWS 1999b). During the winter the snakes hibernate in burrows created by ground squirrels and other burrowing animals. Burrows are generally in upland habitat well above the water table (USFWS 1999b). Giant garter snakes normally select burrows on south and west facing slopes for sun exposure. The GGS breeding season is from March to April and the female gives birth to live young from late July through early September (USFWS 2009b).

There are no CNDDB records for this species within a 5-mile radius of the Study Area. The mosaic of slow-moving mine tailing streams and historic settling ponds in the willow riparian scrub habitat located in the far western portion could provide potentially suitable habitat for this species. However, the lack of open sunny basking sites, unstable gravelly-sandy substrates and distance from preferred habitats located to the west in the greater Sacramento Valley likely precludes the presence of this species within the Study Area. No GGS were observed during the January 2020 field surveys.

BIRDS

Cooper’s Hawk (Accipiter cooperii) and Sharp-shinned Hawk (Accipiter striatus); State Protected

The sharp-shinned hawk is a small raptor with short, rounded wings. This hawk has a long tail that is squared-off at tip with prominent corners. This raptor typically flies with several quick, snappy wingbeats and a short glide, but also soars. Its small rounded head does not project far beyond the wings when soaring. The adult sharp-shinned hawk exhibits a red eye, black cap, and a blue-gray back and upperwings. The white breast, belly and underwing coverts are marked by fine, thin, reddish bars.

The Cooper’s hawk is quite similar looking to the sharp-shinned hawk, although it is slightly larger in size and has a long rounded tail. Both hawks hunt in woodlands, riparian areas and even densely vegetated urban areas. These raptors capture small birds, rodents and reptiles. They often hunt along the edges of woodlands, shorelines, and riparian habitats where migrating passerines are found. Nesting habitat for these raptors consists of woodlands, coniferous forest, and dense oak woodland adjacent or close to open areas.

While there are no CNDDB occurrences of these species within a 5-mile radius of the Study Area, suitable foraging habitat exists for both species throughout the Study Area. Prey items such as passerines and squirrels were observed foraging on the Study Area throughout the surveys. While neither species was observed during the January surveys, potential nesting habitat occurs within the Study Area along Dry Creek and the willow and cottonwood riparian scrub habitats in the western portion of the Study Area.

36

Tricolored Blackbird (Agelaius tricolor). Federal Species of Special Concern, California Species of Special Concern

A close relative of the red-winged blackbird (Agelaius phoeniceus), the tricolored blackbird is distinguished by a white patch underscoring the bright red epaulettes that are prominent in the males of both species. Often found in large flocks of red-winged blackbirds, this species is highly colonial. Nesting colonies usually occur in marshy habitats, often in large stands of blackberry.

While there are no CNDDB occurrences of this species within a 5-mile radius of the Study Area, foraging and nesting habitat exists throughout the western portion of the Study Area in the form of emergent wetland and mining related depression habitats. This species was not observed during the January 2020 surveys, but does have the potential to occur within the Study Area.

Golden Eagle (Aquila chrysaetos). California Species of Special Concern, State Protected

The golden eagle is typically found in open grasslands, pastures, and oak woodland, often near lakes and rivers. Their plumage is dark brown overall, with some white at the base of the tail, and golden-to-blonde feathers on the nape of the neck. The bill and talons are black and the cere (soft membrane that covers the nostrils) and feet are yellow. Immature birds have a broad, white tail band with a black edge and large white patches on the undersides of the wings at the base of the primary feathers. Adult males weigh nine pounds with adult females weighing 12.5 pounds. Masters of soaring, golden eagle can reach speeds up to 200 miles per hour with their 6.5 to 7.5 foot wingspans. Eggs are laid between February and May, usually with two to four eggs per nest. Golden eagles build large stick nests in tall trees, isolated ledges, or cliff walls where they have plenty of room to maneuver. The nest may become huge, as much as eight to ten feet across and three to four feet deep. Threats include human disturbance, loss of habitat, shooting, lead poisoning, and electrocution from power lines.

Suitable foraging and nesting habitat exists throughout the Study Area. An immature golden eagle was observed during the 15 January 2020 survey and is present within the Study Area.

Red-Shouldered Hawk (Buteo lineatus). State Protected

The red-shouldered hawk is a medium-sized, slender Buteo with long legs and a long tail and is smaller than the red-tailed hawk. Upperparts are dark with pale spotting, and rusty-reddish feathers on the wing create the distinctive shoulder patch. The tail has several wide, dark bars; the intervening narrow stripes and the tip of the tail are white, and there is variation in the number of tail bars among adults and juveniles. The habitat that the red-shouldered hawk prefers varies from bottomland hardwoods and riparian areas to upland deciduous or mixed deciduous- conifer forest, and almost always includes some form of water, such as a swamp, marsh, river, or pond. In the west, the red-shouldered hawk sometimes occurs in coniferous forests, and has been expanding its range of occupied habitats to include various woodlands, including stands of eucalyptus trees amid urban sprawl.

37

Suitable foraging and nesting habitat exists throughout the Study Area; a red-shouldered hawk was observed during the 15 January 2020 survey along Dry Creek and is present within the Study Area.

MAMMALS

Special-Status Bats

Bats (Order - Chiroptera) are the only mammals capable of “true” flight. They are nocturnal feeders and locate their prey which consists of small to medium sized insects by echolocation. Bats consume vast amounts of insects making them very effective pest control agents. They may eat as much as their weight in insects per day. Maternity roosts comprised of only females, may be found in buildings or mine shafts with temperatures up to 40 degrees Celsius and a high percentage of humidity to ensure rapid growth in the young. Female bats give birth to only one or two young annually and roost in small or large numbers. Males may live singly or in small groups, but scientists are still unsure of the whereabouts of most males in summer.

Special-status bats with the potential to occur within the Study Area are listed below. While special-status bats were not observed during the January 2020 surveys, they could potentially occur within the Study Area based on the roosting and/or foraging opportunities provided by the various woodland and forested habitats present within the Study Area.

Western mastiff bat (Eumops perotis californicus); California Special Concern species Silver-haired bat (Lasionycteris noctivagans), California Special Concern species

7.0 CONCLUSIONS

7.1 Wetlands

Concurrent with the results of the biological assessment survey, a preliminary jurisdictional determination (PJD) of wetland and “other waters” was conducted by BRS in January 2020, which identified the presence of regulated waters of the U.S. within the Study Area. A small portion of Dry Creek crosses through the Study Area along the far western boundary, and the unnamed intermittent blue-line feature associated with Sawmill Ravine occurs throughout the entire length of the Study Area flowing in an east-to-west direction. Various mining related depressions and ephemeral drainages are also present in portions of the Study Area. Some of these features may be considered jurisdictional by either the Corps, CDFW and/or RWQCB. If so, any proposed mining activities associated within said features will be subject to permits from these agencies.

7.2 Special-Status Plants

Several special-status plant species have the potential to occur on the Study Area based on the presence of suitable habitats and soil types. The special-status plants that have the potential to occur on the Study Area include big-scale balsamroot, dissected-leaved toothwort, white- stemmed clarkia, Mildred’s clarkia, Mosquin’s clarkia, Clifton’s eremogone, California satintail,

38

Red Bluff dwarf rush, Colusa layia, Ahart’s paronychia, California beaked-rush, brownish beaked-rush, Sanford’s arrowhead and Butte County checkerbloom.

7.3 Special-Status Wildlife

Special-Status Invertebrates – The seasonal and emergent wetland habitats and mining related depressions within the Study Area may provide suitable conditions to support vernal pool fairy shrimp, vernal pool tadpole shrimp, and California linderiella. The Study Area does not occur within designated critical habitat for vernal pool fairy and tadpole shrimp.

While two elderberry shrubs were found within the Study Area, the stems of both shrubs were carefully examined for the presence of exit holes that may indicate presence of the valley elderberry longhorn beetle; no exit holes were detected.

Special-Status Amphibians – Dry Creek and the intermittent stream system associated with Sawmill Ravine and the stream-associated backwaters and isolated pools within the historic settling ponds and mine tailing willow riparian scrub habitat within the Study Area may provide suitable conditions to support the foothill yellow-legged frog.

The Sawmill Ravine stream-associated backwaters and isolated pools within the historic settling ponds and mine tailing willow riparian scrub habitats may provide suitable breeding habitat for the California red-legged frog, However, possible high turbidity levels in the water column associated with mining operation runoff and the absence of burrow complexes of fossorial mammals (e.g., California ground squirrels) in close proximity to the Study Area for upland dispersal habitat after the breeding season likely precludes the presence of this species.

Special-Status Reptiles – The historic settling ponds, emergent wetlands, riparian woodland and scrub habitats along the western half of the Study Area may provide suitable conditions to support the northwestern pond turtle. However, these same habitats, along with lack of nearby fossorial mammals burrow for upland refugia habitat and unstable gravelly-sandy substrates do not likely provide suitable conditions to support the giant gartersnake.

Special-Status Raptor Species – Foraging and nesting habitat for the Cooper’s hawk, sharp- shinned hawk, golden eagle, bald eagle, red-tailed hawk, red-shouldered hawk, great-horned owl, American kestrel and other raptors exists throughout the Study Area in the form of the annual grassland, riparian forest, woodland and scrub, seasonal and emergent wetlands, blue oak and mixed foothill pine-interior live oak woodland habitats. Abundant prey resources are present in the form of bird, reptile and mammal species. Red-shouldered hawk and golden and bald eagles were observed within the Study Area during the January 2020 surveys.

While not a state species of special concern but afforded protection by the MBTA, nesting and foraging habitat exists on the site for the great-horned owl (Bubo virginianus), which was observed in the Valley Oak-Sycamore Riparian Forest during the January 2020 surveys.

Special-Status Bird Species – Foraging and nesting habitat for the tricolored blackbird exists throughout the Study Area in the form of the more brushy emergent wetland areas throughout the Study Area.

39

Special-Status Mammals – Suitable roosting and/or foraging habitat for the western mastiff and silver-haired bat species exists throughout the Study Area in the form of the various woodland and forested habitats present.

7.4 Butte County General Plan – Oak Woodland Mitigation Ordinance

The new DRAFT (2018) includes a change in the definition of Oak Woodland. The definition no longer requires oaks to be 10% of the tree canopy in order for the project to be subject to the Ordinance. This simplifies this portion of the draft ordinance and expands the applicability of the ordinance.

The new draft plan sets a cap for the removal of oak woodlands by requiring that 30% remain (no more than 70% removal). This is borrowed from the Butte County Oak Woodland Management Plan. While the context of that plan is voluntary and is a recommendation regarding firewood removal, the county is proposing this same percentage as a cap for discretionary projects.

8.0 RECOMMENDATIONS

 Concurrent with this biological resources assessment, a wetland delineation has been conducted in accordance with U.S. Army Corps of Engineers guidelines to determine the extent of Corps, California Department of Fish and Game, and Regional Water Quality Control Board jurisdictional waters falling within the Study Area boundaries. Any future proposed mining activities that may potentially impact riverine resources associated with Dry Creek and Sawmill Ravine, along with impacts to wetland resources associated with the emergent and seasonal wetlands, may be subject to permits from these agencies.

 Mining activities could expose soil to increased rates of erosion during project periods. During active mining operations, runoff could adversely affect aquatic wildlife resources within the various riverine and wetland habitats. Surface water runoff could remove particles of fill or exposed soils from the site, or could erode soil down-gradient, if flows are not controlled. If water is present within any of these features, deposition of eroded material could increase turbidity, thereby endangering aquatic wildlife resources. Implementation of appropriate mitigation measures would ensure that impacts to aquatic organisms would be avoided or minimized. Mitigation measures may include best management practices (BMP’s) such as silt fencing and check-dams after excavation activities as identified in a Storm Water Pollution Prevention Plan (SWPPP).

 New mining disturbances within the Study Area may result in vegetation removals that could directly destroy nests, eggs, and immature birds, and would remove future nesting habitat for birds, including sensitive species such as migrating songbirds. If impacts to on-site habitats were nesting birds are detected and cannot be avoided, then the removal of the tree, shrub and/or herbaceous vegetative cover will occur outside the breeding season, which is typically between (January) 15 February and August 30 of each year.

40

 If any active raptor nests are present within the Study Area in the future, all mining- related activity must maintain a buffer of at least 150 feet during the breeding season from March to August and the site protected until August 15 or until the young have fledged (typically 3 to 4 weeks). A nesting raptor survey 72 hours prior to the removal of vegetation and/or construction is required to determine presence/absence of nesting raptor species.

 Due to the presence of suitable habitat types, soil conditions, and recent occurrences in the vicinity of the Study Area, several special-status plant species have been identified as having the potential to occur within the Study Area. A protocol-level preconstruction floristic survey should be performed prior to any new mining disturbances to identify the location of any listed special-status plants. Should any mining activities take place near any confirmed listed plant species, a reasonable buffer (TBD in consultation with CDFW) established by CDFW must be maintained until mining activity no longer occurs in that area.

 If a discretionary action is required, the applicant must comply with the Butte County General Plan – Oak Woodland Mitigation Ordinance during all phases of active mining operations. This element discusses proper mitigation measures regarding significant impacts to oak trees such as those that occur within the Study Area. Should any of these trees within the Study Area require removal, the client must hire an arborist to count individual trees and take diameter at breast height (dbh) measurements. Mitigation measures for tree removal will be decided on by the County to reduce impacts to a less than significant level.

ATTACHMENT 3 SITE PHOTOGRAPHS

ATTACHMENT 3 STUDY AREA PHOTOGRAPHS

Photo 1. View of the Study Area in the far eastern portion of the Study Area, facing northwest. Sawmill Ravine is located at the base of the vertical bluffs seen in the background of the photograph.

Photo 2. Blue oak woodland in the far eastern portion of the Study Area.

Photo 3. View of Sawmill Ravine, facing west. The Sacramento Valley floor can be seen in the distance.

Photo 4. Representative view of the unnamed stream feature located within Sawmill Ravine, facing west.

Photo 5. Photograph shows approximate location of proposed haul road along the north-eastern boundary of the Study Area. This area is actively grazed by cattle and consists of annual grassland habitat. Woody vegetation in the background consists of a small stand of mixed foothill pine-interior live oak woodland.

Photo 6. Representative view of willow riparian scrub habitat north of the active haul road in the central portion of the Study Area, facing north.

Photo 7. Lower reach of Sawmill Ravine stream feature, facing west. Floodplain flanking both sides of the channel consists of cottonwood riparian woodland, which has a severe infestation of Spanish broom in the understory.

Photo 8. Photograph taken on top of the easternmost spillway, facing west. Waters conveyed down Sawmill Ravine are discharged over the spillway, where they flow towards the series of active settling ponds, where overflows are discharged through a series of culverts into either the historic settling ponds, or into the large wetland complex of willow riparian scrub (a portion of which can be seen in the upper right-hand portion of the photograph.

Photo 9. Photograph shows representative example of mixed foothill pine-interior live oak woodland along the northern boundary in the western portion of the Study Area.

Photo 10. Photograph shows representative example of the willow riparian scrub habitat in the far western portion of the Study Area.

Photo 11. Photograph shows an active beaver dam impounding water at the far western end of the Study Area in willow riparian scrub habitat.

Photo 12. View of the far western spillway above Dry Creek.

Photo 13. Example of mining related depression associated with one of the historic settling ponds at the western end of the Study Area.

Photo 14. Photograph shows the first active Settling Pond at the western end of the Study Area that directly intercepts stream waters from Sawmill Ravine.

Photo 15. Photograph shows culverts associated with the Settling Pond (viewed in Photo 14) that discharge overflows directly into the large complex of mining related depressions associated with the historic settling ponds and willow riparian scrub habitats at the western end of the Study Area.

Photo 16. Photograph shows representative example of a mining related depression (MRD-1) located in a previously mined portion of the Study Area. Dominant bunchgrasses in the foreground are broomsedge bluestem.

Photo 17. Photograph shows representative view of previously mined lands within the northern-most “spur” of the Study Area. Vegetative cover largely consists of a mix of annual grasses and forbs.

Photo 18. Photograph shows mining related depression (MRD-29) at the northern-most portion of the Study Area. Vegetation assemblages consists of emergent wetland and willow riparian scrub.

Photo 19. Photograph shows the two elderberry shrubs located in the central portion of the Study Area. Stems of both shrubs were carefully examined for the presence of VELB exit holes; none were detected.

Photo 20. Photograph shows series of moderately deep mining related depressions along the south-central boundary of the Study Area. Hydrophytic vegetation was present in, and along the edges of these features but was generally sparse. These clear pools appear to pond water for sufficient hydroperiods that may support vernal pool crustaceans.

Photo 21. Photograph shows complex of braided streams within the interior of large willow riparian scrub habitat north of the active haul road in the central portion of the Study Area.

Photo 22. Chaparral habitat intergrading with foothill pine in the far eastern portion of the Study Area.

Photo 23. Large mining related depression (MRD-12) along the southern boundary of the Study Area, facing southeast. This feature was largely unvegetated except for last season’s remaining stubble of swamp pricklegrass (which is listed as an obligate hydrophytic species) around and beyond the perimeter of this feature.

Photo 24. View of the upper reach of Sawmill Ravine at the eastern end of the Study Area. While high-velocity winter flows were present in this feature at the time of the January 2020 surveys, the cobble and boulder bed may provide suitable breeding habitat for the foothill yellow-legged frog.
