Conditions of Approval for the Roblar Road Quarry

This document contains the list of the 182 Conditions of Approval for the start-up and operation of the Roblar Road quarry approved by the Board of Supervisors on Dec. 14, 2010, Resolution 10-0902. These conditions are to be met by the quarry developer/operator and span the 20-30 year lifetime of the quarry. The Conditions note many local, state and federal agencies that must be involved in granting operational permits and monitoring that the quarry meets operational regulations. However, the quarry operator is allowed to self-monitor many of the Conditions: CARRQ believes he will be unable or unwilling to do this during the lifetime of the quarry.

EXHIBIT E PLP03-0094 Sonoma County Board of Supervisors Resolution 10-0902

Board Conditions of Approval and Mitigation Monitoring Program for the Roblar Road Quarry

Date: December 14, 2010 File No.: PLP03-0094
Applicant: John Barella Tr. And Andrea Barella Tr. Quarry APNs: 027-080-009 and -010
Address: 7175 and 7601 Roblar Road, Sebastopol

Project Description: Request for (1) Zone Change to add the MR {Mineral Resources) overlay zone to the proposed 70 acre mining site (APN 027-080-009} and a 25 foot perimeter setback area around the parcel, (2) Use Permit for Alternative 2 (Alternative Haul Route/Contracted Sales Only}, as modified by the Board of Supervisors, to allow a 20-year mining permit with an annual production limit of 570,000 cubic yards per year, and (3) Reclamation Plan to return the 70 acre mining area to a natural condition with native soil and vegetation suitable for agriculture and open space. The Alternative 2 haul route was modified by the Board to prohibit the use of the adjacent Wilson property encumbered by an Open Space District easement for Alternative 2 Access Road 1. Instead; rather than building segment 1 of the haul road on the Wilson property, the applicant would be required to improve Roblar Road to County Standards from the proposed quarry entrance shown for the proposed Project (DEIR Figure 111-6} westward to the point where the Alternative 2 haul road turns overland off Roblar Road onto Access Road 2 (which is not on land subject to an Open Space District easement). The on-site project access road and quarry entrance would be constructed substantially as described for the proposed project and analyzed and mitigated in the DEIR, i.e., it would connect to Roblar Road approximately 1200 feet east of the existing vehicular access point. All Alternative 2 haul route restrictions and mitigation measures would apply.


The Permit and Resource Management Department {PRMD) is responsible for monitoring the compliance of aggregate operations with all permit conditions and ordinance requirements as part of the ongoing inspection, enforcement, mitigation and monitoring program established by the Aggregate Resources Management (ARM) Plan. In addition, the County conducts periodic inspections of every mining site to fulfill the requirement of the State Surface Mining and Reclamation Act {SMARA). Some of the monitoring for the following conditions of approval will be carried out concurrently through the above activities; in other cases more frequent monitoring or monitoring by a qualified professional or responsible agency has been deemed necessary and added to the on-going monitoring activities.

The monitoring activities planned for each condition of approval along with the responsible person or agency, and the frequency or schedule of monitoring are provided after each applicable condition in the following conditions of approval.

The requirements of this Use Permit run with the real property that is the subject of the project. Successive owners, heirs, and assigns of this real property are bound to comply with all the requirements of these conditions. Prior to any lease, sale, transfer, or conveyance of any portion of the real property that is the subject of the project, the owner shall provide a copy of the adopted conditions to the prospective lessee, buyer, transferee, or one to whom the conveyance is made. All conditions set forth herein shall be applicable to both mining and processing within parcel APN 028-0B0-009, unless otherwise specified. The applicant's obligations under Conditions 111 (sediment control and storm water pollution prevention}, 113 (groundwater seepage), 41, 42, and 43 (indemnification and release agreement), and 171 (reclamation) shall survive the expiration of this Use Permit.

Prior to issuance of any permits (grading, septic, building, etc.) or commencement of clearing or mining activity on parcels defined as APNs 027-080-009 and -010, all of the pre-operational conditions must be met and verified by PRMD staff pursuant to this Use Permit.

The design shall meet the standards of the Sonoma County SMARO. All hydrologic and engineering calculations, including sediment trap efficiency, shall be submitted to the County and the RWQCB for review and approval prior to commencement of project grading. The WQPP consists of several elements, as discussed below, to control the source of sediment and the discharge of that sediment into the adjacent receiving waters of Americano Creek and Ranch Tributary. As part of the WQPP, the applicant shall prepare a Storm Water Pollution Prevention Plan (SWPPP) as required by the RWQCB. The applicant shall submit a copy of the SWPPP that adequately addresses control and reduction of storm water laden with sediment or other pollutants to the County PRMD. The applicant shall comply with requirements set forth by the Regional Water Quality Control Board in the SWPPP Program for annual reporting and water quality sampling, which typically includes annual reports and reports of failed best management practices (BMPs). The SWPPP shall be regularly updated as BMPs are updated and new BMPs are constructed and/or the quarry operation changes. The SWPPP shall be implemented during the initial stage of quarry construction and stay in effect through the completion of reclamation.

Aggressive Source Control: The WQPP shall outline and describe source control measures designed to prevent erosion. Specific measures, as cited below, shall be adapted from the most current edition of the Storm water Best Management Practice Handbook for Construction, published by the California Storm water Quality Association (CASQA}. Equivalent measures deemed more effective by the North Coast RWQCB may be substituted. 

  • Reclamation or stabilization of all quarry slopes and the quarry floor (excluding the working/processing/stockpile/loading/access areas) shall be completed by October 1 of each year. Stabilization measures include hydraulic application of surface stabilizing compounds, hydro-seeding, mulching, or other measures to prevent erosion.
  • To insure accurate compliance with this condition, the applicant shall submit to the Sonoma County PRMD, a site plan or aerial photograph clearly depicting the extent of mining and reclamation on the site every five years during mining and reclamation and at the completion of reclamation;
  • In areas not being actively mined, bare soil shall be protected from erosion with the application of hydraulic mulch or hydro-seeded;
  • In areas requiring temporary protection until a permanent vegetative cover can be established, bare soil shall be protected by the application of straw mulch, wood mulch, or mats;
  • To the extent practical, benches should be back-sloped or provided with rock or straw bale checks so that sediment is trapped on the benches rather than washed into the sediment ponds; and
  • Benches shall drain into adequately sized pipes or rock-lined channels that convey the runoff to the quarry floor. Outlets of pipes shall have appropriate energy dissipaters to prevent erosion at the outfall.

Sediment Retention Measures: The WQPP shall include specific measures to trap eroded sediment on site to prevent a discharge to receiving waters. Specific measures cited below shall be adapted from the most current edition of the CASQA Storm water BMP handbook for construction. The applicant shall install sediment retention measures prior to winter (on or about October 15) or in areas receiving surface water runoff in the dry season (e.g. the areas receiving seepage from the quarry walls). Sediment retention measures shall be regularly inspected by quarry personnel and corrective action shall be conducted in the event that the measures fail. Inspection and performance of the sediment retention measures shall be included in the SWPPP and included in the required annual report. Equivalent measures deemed more effective by the North Coast RWQCB may be substituted.

  • Silt fences, fiber rolls, and straw bale barriers shall be used on bare slopes not being actively mined to intercept and trap sediment carried by sheet flow;
  • The program shall include a description of the construction method for the sediment ponds, including the design storm and spillways;
  • The applicant shall design the proposed sediment ponds to the maximum size practical for the available space. The sediment control basin shall include a fore bay to trap coarse soil particles. Recognizing that the sediment ponds may not be large enough to trap very fine particles such as clay, the design shall include supplemental treatment that can be used as needed to meet the water quality discharge criteria for this project.
  • Supplemental treatment may be chemical treatment that promotes fine particle settlement, mechanical filters to remove fine particles, or other measures approved and required by the North Coast RWCQB for this particular project;
  • All runoff from actively mined or reclaimed areas shall be directed through the sediment control basins.

Implement Contaminant-Control BMPs: The applicant shall implement BMPs to reduce the potential for discharge of contaminants to storm water runoff. These BMPs shall be designed by a civil engineer and the design engineer shall oversee BMP installation. To minimize the introduction of contaminants which may degrade the quality of water discharged from the site, the following measures shall be taken:

  • Fueling and maintenance of all rubber-tired loading, grading and support equipment shall be prohibited within 100 feet of drainage ways. Fueling and maintenance activities associated with other less mobile equipment shall be conducted with proper safeguards to prevent hazardous material releases.
  • All refueling and maintenance of mobile vehicles and equipment shall take place in a designated area with an impervious surface and berms to contain any potential spills;
  • The site shall be controlled by maintaining security fencing and locking gates and posted trespass signs at all vehicular access points to the site to prevent unauthorized entry;
  • Runoff from the access roads shall be captured, retained and conveyed to the sediment control pond; and
  • All chemical dust suppressants and slope stabilization chemicals or polymers, and sediment pond enhancement chemicals or polymers shall be EPA approved and shall be used strictly according with the manufacturer's directions. An accurate accounting of the kinds and quantities of these materials used on the site shall be maintained by the operator.  Mitigation Measure C.2a

Mitigation Monitoring: PRMD Grading and Storm water, SCWA, and RWQCB, as applicable, will review the WQPP to verify that the storm drain and sediment control ponds are designed to handle storm events and that best management practices are utilized for sediment, erosion, and contaminant control. The RWQCB will also insure that the plan meets their requirements for storm water pollution prevention.

The plan shall consider management of seepage during operation, as well as, in the long term following reclamation and be based on conservative estimates of seepage derived from measured
hydraulic conductivities in the weathered and un-weathered Wilson Grove Formation and then Tolay Volcanics. The drainage plan shall include measures to ensure that the quarry wall seepage can be managed by storm water flow conveyance structures and that these structures would not be overwhelmed during the 2-, 10-, 25-, and 100-year storm events. Mitigation Measure C.3

Mitigation Monitoring: PRMD Grading and Storm water will review drainage plans to verify that storm drainage facilities are designed and installed to detain flows, including groundwater seepage, so that those structures are not overwhelmed during the 2-, 10-, 25-, and 1DO-year storm events.

Condition 114
This condition applies to the Use Permit and Reclamation Plan
The applicant shall fully incorporate and implement all measures specified in the approved Water Management Plan, including those reflected in this mitigation measure as follows:
The applicant/operator shall regularly sample and analyze all water collected within the quarry footprint and in production well DW-2 for the same suite of analytes used at the adjacent Roblar Landfill during the 2004 through 2008 monitoring events, and at the project site during the 2007/08 monitoring events. The QA/QC protocol for the sampling and analysis program shall be completed by an environmental professional knowledgeable of current surface water/groundwater regulations and sampling procedures.
The sediment control basin sampling and analysis schedule shall be developed in conjunction with the basin management operations. Prior to the release of water from any sediment control basin, the quarry shall obtain representative samples of the water held in the basin and submit the samples for analysis of VOCs and metals by a California state certified analytical laboratory. Once samples and final analytical results are received, the quarry shall determine the appropriate routing of the water based on applicable water quality standards. Basin water quality sampling schedules, guidelines, protocols, and procedures required to collect and analyze representative samples from each basin will be provided in a detailed Sediment Control Basin Sampling and Analysis Plan, subject to review and approval by the County of Sonoma PRMD, and as applicable, the RWQCB, prior to commencement of operation of the treatment system.
Groundwater extracted from Well DW-2 shall be sampled and analyzed once every 24-hours during periods of sustained or cyclic pumping, and at the end of each pumping episode during times of intermittent use of the well (intermittent use means pumping episodes separated by more than 24 hours).

In the event that the monitoring of the water collected within the quarry footprint or production well DW-2 contains contaminants exceeding water quality standards, such water shall be treated on-site {e.g., use of granular activated carbon vessels to treat VOCs, and use of an ion-exchange resin system to treat metals} until concentrations meet acceptable water quality standards and subsequently be available only for either direct onsite reuse or temporary storage prior to onsite reuse. In addition, in the event that VOCs and/or metals are detected in the water in the sediment control basins exceeding water quality standards, the sediment within the respective sediment control basin would also be sampled and analyzed for VOCs and/or metals prior to removal. In the event that VOCs and/or metals are detected in this sediment at concentrations above applicable standards, the sediment shall be removed, transported and disposed of off-site at an appropriate licensed facility in accordance with all applicable state and federal regulations." Mitigation Measure C.4e:

Mitigation Monitoring: Prior to issuance of a grading permit, PRMD staff will verify that a detailed Sediment Control Basin Sampling, Analysis, Monitoring, and Reporting Plan is submitted in conformance with the above requirements for review and approval by PRMD and RWQCB, as applicable.

Condition 115
This condition applies to the Use Permit and Reclamation Plan
The applicant shall incorporate into the final project drainage plan a hydrologic strategy that replaces potential base flow in Ranch Tributary lost due to the quarry operation. This
mitigation measure requires a) continuation of the base flow monitoring program that commenced in Spring 2007, and b) determining from that data whether substantial changes in base flow is occurring during the operation of the quarry. If a reduction in base flow due to project activities becomes evident through long term monitoring, the applicant shall adapt their on-site surface water discharge program as needed to provide additional infiltration (e.g. recharge basins, additional infiltration trenches} to replicate pre-project base flows. Sonoma County PRMD shall review and approve the monitoring plan and on-site surface water discharge system prior to implementation. The applicant shall continue to monitor the flows in Ranch Tributary to ensure consistent replacement of base flow. The applicant shall submit quarterly reports to the Sonoma County PRMD and Sonoma County Water Agency (SCWA} that details system monitoring and performance.Mitigation Measure C.5a (also addresses MM D.1c)

Mitigation Monitoring: Prior to issuance of a grading permit for work within the quarry footprint, PRMD Project Review and Drainage Review staff will review the monitoring program as well as grading and drainage plans to verify that they include an infiltration system designed to address the retention of base flow conditions in Ranch Tributary. PRMD ARM Plan staff and Drainage Review, in conjunction with SCWA, will review the quarterly monitoring reports to verify the performance and require adaptive measures as necessary.

Condition 138
This is a condition of the Use Permit
The project applicant shall implement measures to minimize and avoid take of California red-legged frog (CRLF) that would additionally benefit pond turtles and foothill
yellow-legged frog, if present. The following measures are derived from the Programmatic Biological Opinion {PBO) for impacts to California red-legged frog (United States Fish and Wildlife Service (USFWS, 1999). The applicant shall obtain formal consultation with the USFWS and issuance of a project specific Biological Opinion. The following actions will minimize impacts to these species.

Construction-Related Measures:

  • A USFWS-approved biologist shall conduct a training session for all construction personnel. At a minimum, the training will include a description of the CRLF and their habitat, and the general measures that are being implemented to protect the CRLF as they relate to the project.
  • The mitigation pond shall be created and suitable for receiving relocated CRLF prior to the removal of Center Pond and surrounding upland habitat.
  • Following construction of the mitigation pond and no more than 14 days prior to the initiation of grading activities near Center Pond, a USFWS-approved wildlife biologist shall capture all CRLF and other special-status aquatic species and relocate them to the mitigation pond.
  • A USFWS-approved biologist shall be present during initial grading activities in and surrounding Center Pond until CRLF have been removed. Thereafter, an onsite person shall be designated to monitor onsite compliance with all minimization measures. The USFWS-approved biologist shall ensure that this individual receives training consistent with that outlined in the Biological Opinion.
  • During all phases of project operations, all trash that may attract CRLF predators shall be properly contained and removed from the site.
  • The fueling and maintenance of vehicles and other equipment shall occur at least 20 meters from any riparian habitat or water body.

Pond Design, Management, and Monitoring

  • The project applicant shall coordinate with the USFWS to select a suitable site for a new mitigation stock pond of equal or greater size to Center Pond within the property boundaries. The location and design of the new pond shall conform to guidelines of the USFWS Recovery Plan for CRLF (USFWS, 2002} and shall also include a permanent upland habitat buffer of no less than 250 feet around the pond. The final pond design shall be approved by the USFWS as a requirement of the project Biological Opinion. The mitigation pond should be created and functioning prior to the initiation of ground disturbing activities within 250 feet of Center Pond.
  • The mitigation pond shall be designed to provide CRLF breeding habitat and shall include areas with deep-water cover for adult, juvenile and metamorphic red-legged frogs and shallow areas to provide for tadpole and juvenile rearing. The pond shall be designed to pool to a depth of between 3 to 4 feet and to maintain at least 1.0 foot of standing water through September 15 during years with average rainfall. To ensure sufficient water is available to support CRLF breeding, a qualified hydrologist shall be consulted to assess the amount of water that will be available at the selected site during dry, average, and wet years. A design plan shall be prepared to include a grading plan and cross-section plan indicating pond depth and dimensions. The basin shall be contoured based on the above design, and lined with clay or a similar impervious substrate to ensure water holding capacity that meets minimum performance standards and specifications.
  • The mitigation pond shall be vegetated in accordance with the guidelines set forth in the Red-legged Frog Recovery Plan. Relocated vegetation shall salvage and utilize native emergent and aquatic vegetation from Center Pond whenever possible. Upland habitat surrounding the pond should be seeded with native grassland cover species.
  • An adaptive management plan shall be developed for the mitigation pond consistent with the USFWS Recovery Plan for CRLF (USFWS, 2002} and project Biological Opinion. The plan shall include a program to monitor pond performance over time and discourage the presence of non-native vegetation and bullfrogs. During the initial five year monitoring period, annual hydrologic, vegetation and wildlife surveys shall be performed to document pending conditions, the establishment of aquatic vegetation and to monitor California red-legged frog use of the pond.

The adaptive management plan shall provide provisions to quantify site conditions relative to performance standards for a period of five years, to include:

  1. Ability to maintain standing water at a depth of at least 1.0 foot within at least 50 percent of the pond area through September 15 during a year with average rainfall
  2. Presence of CRLF in any life history stage, to be determined by egg mass surveys and focused nighttime surveys for adults and juveniles.
  3. The presence of native emergent or aquatic vegetation covering at least 10 percent of the pond edge.
  4. Absence of persistent, self-sustaining populations of non-native CRLF predators, particularly bullfrogs.

The adaptive management plan shall include contingency measures to respond to inadequate hydrologic conditions (if later identified) and provide for control of non-native vegetation and CRLF predators, if identified in the mitigation pond. If bullfrogs are identified, the preferred management method shall be manual (hand) removal using a gig or other means. This method maintains the availability of aquatic habitat for red-legged frogs and sustains aquatic vegetation. If hand removal of bullfrogs proves ineffective, the pond shall be drained and dried between October 1 and November 15 (following metamorphosis of red-legged frog tadpoles} to break the bullfrog life cycle.

An invasive plant species management plan shall be incorporated into the adaptive management plan to provide for the management and removal of invasive aquatic vegetation, if present. The preferred management method shall be for manual (i.e., non-chemical) removal of invasive species, whenever possible. Pond management shall continue for the duration of the proposed project, or as required by the Biological Opinion. Mitigation Measure 0.3

Mitigation Monitoring: Prior to grading permit issuance, PRMD will verify that the applicant has obtained a biological opinion and necessary clearances from USFWS for establishment of the mitigation pond, relocation of any red-legged frogs, and an adaptive management plan. Ongoing Monitoring and Reporting to PRMD and USFWS shall be accomplished in compliance with the project biologist and USFWS requirements.

Condition 139
This is a condition of the Use Permit
Avoid disturbing active nests of raptors and other special-status birds through preconstruction surveys and creation of no-disturbance buffers during ground-clearing and grading activities associated with initiation of each mining phase. If site preparation activities (i.e., ground clearing and grading, including removal of trees or shrubs} are scheduled to occur during the non-breeding season (September 1 through January 31), no mitigation is required.  If site preparation activities are scheduled to occur during the breeding season (February 1 through August 31), the following measures shall be implemented to avoid potential adverse effects to nesting raptors and other special-status birds:

  • A qualified wildlife biologist shall conduct preconstruction surveys of all potential nesting habitats within 500 feet of construction activities where access is available.
  • If active nests are found during preconstruction surveys, a no-disturbance buffer acceptable in size to CDFG shall be created around active raptor nests and nests of other special-status birds during the breeding season or until it is determined that all young have fledged. Typical buffers include 500 feet for raptors and 250 feet for other nesting special-status birds. The size of these buffer zones and types of construction activities restricted in these areas may be further modified through coordination with CDFG and will be based on existing noise and human disturbance levels at each project site. Nests initiated during construction are presumed to be unaffected and no buffer is necessary. The ''take" of any individuals is prohibited.
  • If preconstruction surveys indicate that nests are inactive or potential habitat is unoccupied during the construction period, no further mitigation is required. Trees and shrubs within the project footprint that have been determined to be unoccupied by special-status birds or that are located outside the no-disturbance buffer for active nests may be removed. Mitigation D.4a

Mitigation Monitoring: If site preparation activities are scheduled to occur during the breeding season {February 1 through August 31), PRMD will verify that preconstruction surveys are completed and buffer areas established through consultation with the CDFG, as necessary. Ongoing Monitoring and Reporting to PRMD and CDFG shall be accomplished in compliance with the project biologist and CDFG requirements.

Condition 140
This condition applies to the Use Permit and Reclamation Plan
The applicant shall avoid disturbing potential burrowing owl burrows through preconstruction surveys and creation of no-disturbance buffers during ground-clearing and grading activities associated with initiation of each mining phase. 

  • No more than 2 weeks before grading and ground-clearing activities begin prior to each of the three mining phases; a survey for burrowing owls shall be conducted by a qualified biologist within 500 feet of the earthmoving activities. The survey shall conform to the most current protocol described by the California Burrowing Owl Consortium (presently the 1993 protocol). If burrowing owl habitat is identified during the initial survey, a complete owl survey consisting of four site visits shall be performed as detailed in the Consortium guidelines.
  • If occupied owl burrows are found during the surveys, a determination shall be made by a qualified burrowing owl biologist as to whether or not proposed project activities would affect the occupied burrows or disrupt reproductive behavior. If it is determined that the project would not adversely affect occupied burrows or disrupt breeding behavior, project implementation may proceed without any restriction or mitigation measures. If it is determined that the project could adversely affect occupied burrows during the August 31 through February 1 non-breeding season, the subject owls may be passively relocated from the occupied burrow(s) using one-way doors. There shall be at least two unoccupied burrows suitable for burrowing owls within 300 feet of the occupied burrow before one-way doors are installed.
  • The unoccupied burrows shall be located 160 feet from construction activities and can be natural burrows or artificial burrows constructed according to current design specifications. Artificial burrows shall be in place at least one-week before one-way doors are installed on occupied burrows. One-way doors would be in place for a minimum of 48 hours before burrows are excavated.
  • If it is determined that the project would physically affect occupied burrows or disrupt reproductive behavior during the nesting season (February 1 through August 31) then avoidance is the only mitigation available {California Burrowing Owl Consortium 1993; CDFG 1995). Implementation of ground-clearing and grading activities shall be delayed within 250 feet of occupied burrows until it is determined that the subject owls are not nesting or until a qualified biologist determines that juvenile owls are self-sufficient or are no longer using the natal burrow as their primary source of shelter.  Mitigation Measure D.4b

Mitigation Monitoring: PRMD will verify that preconstruction surveys are completed for burrowing owl, buffer areas established, and avoidance accomplished, as necessary for initial grading and each phase of mining. Ongoing Monitoring and Reporting to PRMD and CDFG shall be accomplished in compliance with the project biologist and CDFG requirements.

Condition 141
This is a condition of the Use Permit
Avoid and minimize impacts to badgers through preconstruction surveys prior to ground clearing and grading in annual grasslands habitat or areas that are known or suspected to support badger.  Within 30-days prior to initiation of each mining phase, a qualified biologist shall survey for badgers within 100-feet of project activities. If no evidence of badger presence is detected, no further mitigation is required. If evidence of badgers is identified, the following measures are required to avoid potential impacts to this species:

  • Use exclusion techniques to passively relocate any badgers that are present in project areas or within 50 feet of project activities. When outside the project area, but within 50 feet of activities, vacated dens shall be temporarily covered using plywood sheets or similar materials.
  • To reduce the risk of badger mortality from vehicles, the use of private (non-county operated) haul roads shall be limited to daylight hours during the March to June badger pupping season with gated access.
  • A 25 mile-per-hour speed limit shall be posted for roads on the site.  Mitigation Measure 0.5

Mitigation Monitoring: PRMD will verify that preconstruction surveys are completed for badgers, dens covered, and relocation accomplished, as necessary, for initial grading and
each phase of mining. Ongoing Monitoring and Reporting to PRMD and CDFG shall be accomplished in compliance with the project biologist and CDFG requirements.

This is a condition applies of the Use Permit
Avoid disturbing active roosts of special-status bats through preconstruction surveys and creation of no-disturbance buffers during ground-clearing and grading activities associated with initiation of each mining phase, as well as during project activities related to remodeling and/or renewed use of the existing buildings.  Prior to construction activities (i.e., ground-clearing and grading, including removal of trees or shrubs, building remodeling, renewed building use) within 200 feet of trees or buildings potentially supporting special-status bats, a qualified bat biologist will survey forspecial-status bats. If no evidence of bats (i.e., direct observation, guano, staining, strong odors) is present, no further mitigation is required.

If evidence of bats in trees on the property is observed, the following measures are required to avoid potential adverse effects to special-status bats:

  • A no-disturbance buffer of 100-feet, or other suitable distance determined in coordination with CDFG, will be created around active bat roosts during the breeding· season (April 15 through August 15). Bat roosts initiated during construction are presumed to be unaffected, and no buffer is necessary. However, the "take" of individuals is prohibited.
  • Removal of trees showing evidence of bat activity will occur during the period least likely to impact the bats as determined by a qualified bat biologist (generally between February 15 and October 15 if winter hibernacula are observed or between August 15 and April 15 if maternity roosts are present). If known bat roosting habitat is destroyed during tree removal activities, artificial bat roosts shall be constructed in an undisturbed area of the property, at least 200 feet from any project activities. The design andocation of the artificial bat roost(s) shall be determined by a qualified bat biologist.

If evidence of bats in existing buildings on the property is observed, the following measures are required to avoid potential adverse effects to special-status bats:
 

  • Prior to any remodeling activities and/or renewed use of existing buildings with observed bat activity, a qualified bat biologist shall review design drawings and use plans for the building(s). The biologist shall then make a determination, in coordination with CDFG, whether the bats would need to be evicted in order to implement the remodeling/new use of the structures, or if the bats would not be affected and should remain in the structure. If eviction is deemed necessary, the bats shall be transferred to an artificial roosting site. The artificial roost shall be constructed in an undisturbed area of the property, at least 200 feet from any project activities. The design and location of the artificial bat roost(s) shall be determined by a qualified bat biologist.  Mitigation Measure 0.6

Mitigation Monitoring: PRMD will verify that preconstruction surveys are completed, buffer areas established, habitat created, and relocation of bats occurs, as necessary, prior to tree removal, building modification, initial grading, and initiating each phase of mining. Ongoing Monitoring and Reporting to PRMD and CDFG shall be accomplished in compliance with the project biologist and CDFG requirements.

Condition 143
This condition applies to the Use Permit and Reclamation Plan
The project would impact the federally and state listed California Tiger Salamander (CTS} and require compliance with the federal and state Endangered Species Acts. Because the project would impact wetland subject to the authority of the U.S. Corps of Engineers (Corps} pursuant to Section 404 of the Clean Water Act, the project applicant, through the Corps. shall be required to consult with the USFWS in compliance with Section 7 of the federal Endangered Species Act. Through this consultation process the USFWS will define the necessary mitigation to compensate for the unavoidable impacts to the CTS and its breeding and upland habitat and issue its findings in a Biological Opinion (BO) for the project. Following the provisions of Section 2080.iof the California Fish and Game Code, the California Department of Fish and Game (CDFG) will review the incidental take statement in the BO and determine. if it is consistent with the requirements of the California Endangered Species Act (CESA). If CDFG determines that the federal authorization is not consistent with the CESA, the project proponent shall apply for a State Incidental Take Permit under section 2081(b) of the CDFG Code.

Although the project site is west of and outside the Santa Rosa Plain Conservation Area, mitigation for impacts to CTS breeding and upland habitat shall be consistent with the CTS mitigation identified in the Santa Rosa Plain Conservation Strategy (2005) and the Programmatic Biological Opinion (USFWS, 2007}. The appropriate mitigation ratio shall be negotiated with the USFWS and CDFG, and shall be no less than 1:1. Under the Santa Rosa Plain Conservation Strategy (2005), the agencies concluded that compliance with the interim mitigation guidelines is sufficient to mitigate significant effects to listed species.

The following measures are recommended to minimize the possible "take" of CTS, as defined by the federal and state Endangered Species Acts. These measures are identified in the Santa Rosa Plain Conservation Strategy (2005) and the Programmatic Biological Opinion (USFWS, 2007) to minimize and avoid project impacts to CTS. These measures include actions to be implemented prior to construction, and during construction.

Pre-Construction Minimization and Avoidance Measures: One year prior to initiation of grading and other ground-disturbing activities at the project site, exclusion fencing with one-way ramps, one-way doors, or similar USFWS-approved exclusion devices shall be installed around the project impact area and each phase of mining to passively exclude
CTS from accessing the impact area. The fence will remain in place for at least one season (October through June of the following year) unless CDFG and the Service require it to remain in place for a longer period of time. Following removal of the fence and ramp system, and prior to the following rainy season, a more permanent structure will be installed, either a solid fence or curb structure that is high enough to prevent CTS from accessing the project impact area once construction begins. The fence and ramp setup shall be installed prior to the first rains in the fall, or by October 15th and shall remain in place until the larvae have exited or been removed from Center Pond. The fence shall prevent migrating CTS from accessing the project site, and the one-way ramps shall allow dispersing CTS to exit the project impact area but prevent them from returning to the impact area. The area in which the fence and ramp system is to be installed shall be fenced to prevent cattle from accessing the site as the cattle will knock down the fencing and trample the one-way ramps. Prior to installation of the fence and exclusion system, a plan shall be submitted to the USFWS and CDFG for approval of the design and procedures for maintaining the fence and ramp system.

Construction Minimization and Avoidance Measures: A qualified biologist(s) or designated trained monitor{s) shall be onsite during initial groundbreaking activities.

Condition 161
This condition applies to the Use Permit and Reclamation Plan
Prior to grading permit issuance for on-site improvements, the applicant shall submit a comprehensive dust control and meteorological monitoring program for PRMD review to minimize fugitive dust impacts from the project.  Elements of the dust control program (especially during the dry season) for project components include, but are not necessarily limited to, the following:

  • Water all active unpaved vehicle circulation areas daily, using reclaimed water whenever possible. Watering should be sufficient to prevent airborne dust from leaving the site.
  • Increased watering frequency whenever wind speeds exceed 15 miles per hour during dry conditions.
  •  Suspend excavation activity when winds {instantaneous gusts) exceed 25 miles per hour during dry conditions.
  • Cover all trucks hauling soil, sand, and other loose materials, or require all trucks to maintain at least two feet of freeboard (i.e., the minimum required space between the top of the load and the top of the trailer) or CHP standards.
  • Sweep paved roadways (with water sweepers using reclaimed water if possible} at the end of each day if visible soil material is carried onto adjacent paved roads.
  • Hydro seed or apply soil stabilizers to inactive exposed soil areas {as presented in the quarry's reclamation and water quality control plan}.
  • Exposed soil stockpiles shall be enclosed, covered, watered daily or treated with (non-toxic} soil stabilizer.
  • Limit traffic speeds on unpaved roads and circulation areas to 15 miles per hour.
  • Designate a person or persons to monitor the dust control program and to order increased watering, as necessary, to prevent transport of dust offsite. The operator shall have at least one employee who is a certified visual emissions evaluator.
  • Install wheel washers or other washing method (e.g., water sprayers or use of a water depression crossing) so that that tires or tracks of all exiting trucks leaving the site are cleaned of dirt and gravel to minimize tracking these materials onto public roads.
  • Conduct blasting activities by using water injection when drilling to control drilling dust, using sequential delay timing schemes to generate effective rock fragmentation and vibration control to minimize blasting dust, remove loose overburden to prevent dilution of mined rock, which lessens the amount of fine material that can become airborne by blasting, and as needed, during dry summer periods, water onto blast areas to further mitigate dust.
  • Ensure covers over the quarry's crushers (e.g., bag houses or sheds} are in place to minimize fugitive dust during crushing operations. With certain equipment, the use of water or foam spray may be the most effective method to be used, as determined in consultation with the Air District.
  • The applicant shall retain a qualified meteorological consultant to design and implement a wind monitoring program at the quarry site during project construction and operations.The monitoring program shall be limited to providing wind speed and direction information sufficient to implement these specific dust mitigation measures. The meteorological consultant shall conduct an initial field meteorological study to select the equipment and establish onsite locations for wind speed monitoring; the meteorological consultant shall use that information to develop an operating plan for the on-going meteorological monitoring program. The meteorological consultant shall prepare a design and operating plan for the meteorological monitoring (subject to the approval of the County). The meteorological consultant shall supervise the long-term operation of the meteorological monitoring program, regularly preparing and submitting to the County a report summarizing the results of the wind monitoring program. (For the first year, quarterly reports shall be required; yearly meteorological monitoring reports may be more appropriate after the first years’ experience.) The long-term meteorological monitoring program shall be reviewed periodically by the meteorological consultant and, subject to the approval of the County, adjustments made to reflect the experience and understanding of wind conditions and the related experience with dust generation and control at the quarry.

The meteorological monitoring plan shall include the basic elements in Attachment AQ-1, General Meteorological Monitoring Guidelines for Roblar Road Quarry, which generally discusses aspects of a well-designed and -operated meteorological monitoring system. These elements include use of suitable equipment, proper instrument siting and maintenance practices, electronic data recording and preservation, periodic quality control audits of the station equipment and operating practices, and frequent review of the resulting data. The meteorological consultant shall consider each element in developing a plan that addresses plan objectives.

On-going wind monitoring shall be conducted at the project site during the quarry construction and long-term operation, especially during any dry periods of the year when winds are anticipated to exceed 15 mph at the quarry. As part of the wind monitoring program, suitable anemometry shall be employed to regularly monitor winds at locations within the project site subject to fugitive dust, including quarry slopes being actively mined, stockpiles, unpaved travel paths being used for mobile equipment, and where processing operations are occurring. The wind monitoring shall measure and report, at a minimum, average wind speeds and wind gust speeds during the operating hours of the quarry. The measurement intervals for average wind speed (initially anticipated to be one- or two-minute measurements that are made up of 60 consecutive 1- or 2-second samples, taken once every 15-minutes) and wind gust duration {initially anticipated to be a five- to ten-second gust, extracted as the highest 5 consecutive samples among the 60 samples that make up an average wind speed reading) shall be reviewed and modified,  as appropriate, by the meteorological consultant as a part of the development of an operating plan for the on-going meteorological monitoring.

All applicable electronic and manually measured wind data shall be time-stamped and recorded, so that it can be cross-referenced or linked to time-stamped entries in a (manual or electronic)- log book that describe the specific dust control measures or changes in operations made in response to attaining the identified wind speed criteria.

- If, based on the wind monitoring, wind speeds at an active quarry area are found to exceed 15 miles per hour, watering frequency shall be increased and/or other appropriate dust control methods of equal or better effectiveness shall be implemented within the area of effect. Quarry personnel shall put into action and shall document the specific dust control measures or changes in operations that were implemented when the identified 15 miles per hour wind speed was exceeded. These measures shall continue until wind speeds decrease to less than 15 miles per hour, as recorded on two successive regular measurements.
- If wind gusts during quarry operations are determined to exceed 25 miles per hour at any active quarry area of the quarry and those quarry operations generate any visible dust, that dust-generating activity in the area of effect shall be suspended until such time wind gust speeds in that area clearly subside. Quarry personnel shall put into action and document the change in operations that were implemented when the identified 25 miles per hour wind speed was exceeded. These measures shall continue until wind gust speeds decrease to less than 25 miles per hour, as recorded on two successive regular measurements.

  • Automated dust control systems shall be used (e.g. automated sprinkler systems) to maintain proper surface moisture in the stockpiles before sufficient vegetative cover in the stockpiles has been established.
  • If determined to be needed by the meteorological consultant, the applicant shall plant native evergreen trees along the perimeter of the quarry footprint to further minimize wind from entering the active quarry area. {This would be in addition to the trees already proposed to be planted in the vicinity of the proposed office, equipment storage area and parking lot, and along the proposed access road.) The specific tree type, location, and number of rows and spacing of trees shall be determined by the meteorological consultant.
  • The quarry's dust control monitor shall provide nearby landowners (within a radius of potential effect as determined by the meteorological consultant) with a contact phone number for the quarry's dust control monitor for off-site dust complaints that may arise associated with the quarry. The dust control monitor shall determine the cause of the complaint and ensure that measures are implemented to correct the problem. Mitigation Measures FA, F.1d
  •  
  • Mitigation Monitoring: PRMD will review the applicant's comprehensive dust control and meteorological monitoring program to insure it includes the above measures. PRMD will review the applicant's wind monitoring data documenting the changes in dust control measures that were implemented when winds exceeded 15 mph and changes in operations that were implemented when winds exceeded 25 mph.

  • As described in Mitigation measure F.1a, the applicant shall utilize electricity to power the mobile processing plant instead of using the proposed diesel-powered generator.
  • The applicant shall fuel on-road and off-road vehicles with alternative fuels {such as biodiesel and compressed natural gas) to the extent feasible.
  • Other measures, including those listed in Mitigation Measures F.1e {which will limit the use of diesel-powered equipment), shall be employed and quantified to achieve the maximum feasible reduction in GHG emissions from quarry operations.
  • If the applicant is unable to reduce emissions to below 1,100 MT C02e per year using the above measures, the applicant shall submit a detailed plan for PRMD review and approval demonstrating offset of all remaining project emissions above that threshold. Any offset of project emissions shall be demonstrated to be real, permanent, verifiable, enforceable, and additional, as determined by PRMD in its sole discretion. To the maximum extent feasible, as determined by PRMD, offsets shall be implemented locally. Offsets may include but are not limited to, the following (in order of preference):

i. Onsite offset of project emissions, for example through development of a renewable energy generation facility or a carbon sequestration project (such as a forestry or wetlands project for which inventory and reporting protocols have been adopted). If the applicant develops an offset project, it must be registered with the Climate Action Reserve or otherwise approved by PRMD in order to be used to offset project emissions. The number of offset credits produced would then be included in the annual inventory, and the net (emissions minus offsets) calculated.
ii. Funding of local projects, subject to review and approval by PRMD that will result in real, permanent, verifiable, enforceable, and additional reduction in GHG emissions. If the BAAQMD or Sonoma County develops a GHG mitigation fund, the applicant may instead pay into this fund to offset GHG emissions in excess of the significance threshold.
iii. Purchase of carbon credits to offset emissions to below the significance
threshold. Only carbon offset credits that are verified and registered with the Climate Action Reserve, or available through a County approved local GHG mitigation bank or fund, may be used to offset project emissions.  Mitigation Measure F.6b
