The purpose of the law is to establish a reporting and monitoring program to assure implementation of recommended mitigation measures. The following monitoring program is recommended as part of the South Poway Planned Community: CalMat-Poway Subsequent EIR {May 1990}. The subsequent EIR discusses the reclamation plan and aggregate extraction on the approximately 166-acre site located north of Beeler Canyon Road and south of Kirkham Road in the South Poway area. This proposal involves Reclamation Plan 89-05 and Conditional Use Permit 89-05. The following excerpts from the subsequent EIR address the mitigation monitoring and reporting program for seven types of impacts along with the analysis of significance. The seven impacts addressed are: Biological resources, land use, aesthetics/landform alteration, traffic, noise, air quality, and utilities. A complete discussion of the potentially significant environmental impacts and mitigation measures for each topic is con- tained within Section 4 Environmental Analysis of the subsequent EIR. 4.1 BIOLOGICAL Resolution No. 90-163 ,~age 6 RESOURCES MITIGATION MONITORING AND REPORTING PROGRAM References in the following monitoring requirements apply to the same numerical designations in the mitigation section above. 1) The spring survey would be included as a condition of the CUP. 2) The CUP will depict an open space easement over the riparian habitat. During the annual review of the CUP, a biologist will confirm that no disturbance has occurred to the wetland resources. 3) Approval of the restoration plan will incorporate provisions of the coastal sage scrub vegetation and monitoring program. 4) Partial mitigation for the southern California grassland would include off-site acquisition of e.,fisting high.quality grassland or degraded grassland which could be enhanced. 5) Payment toward the California gnatcatcher study and or acquisition funding will be made a condition on the CUP. ANALYSIS OF SIGNIFICANCE propoxcd. The mitigation measures proposed by the applicant do not reduce the significant adverse biological resource.impacts to a level below significance. 4.2 LAND USE Resolution No. 90-163 Page 7 MITIGATION MONITORING AND REPORTING PROGRAM Closing Bcclcr Canyon Road to all heavy truck traffic entering and leaving the CalMat - Poway operation by providing an internal'road with access via Kit 'kham Road within one ye-ar two years of approval of expansion would be a condition of approval for the Conditional Use Permit. ANALYSIS OF SIGNIFICANCE The proposed project is substantially in conformance with the General Plan and the South Poway Plam~cd Community regulations and no significant land use impacts have been identified. Regarding adjacent land use impacts, significant impacts would be mitigated to a level below significance with the rerouting of heavy truck traffic on a private access roadway built to public road standards with access via Irdrkham Road and with the barring of all heavy truck traffic on Beeler Canyon Road. Resolution Ilo. 90-163 4.3 AESTHETICS/LANDFORM Page 8 ALTERATION MITIGATION MONITORING AND REPORTING PROGRAM City staff would review and City Council would approve a revised Reclamation Plan for the CalMat - Poway site concurrent with thc approval of thc Conditional Use Permit. The revised Reclamation Plan would be monitored annually to ensure on-going revcgctation and reclamation are in conformance with the approved Reclamation Plan. AN,~kL,YSIS OF SIGNIFICANCE There arc significant impacts associated with thc landform alteration of the 166-acre CalMat - Poway site. Because thc topography range is prominent and currently vacant and because the extraction process necessitates removal of the landform, impacts to the landform of thc proposed project are considered to be significant. An environmentally sensitive Reclamation Plan which includes a phased or concurrent rcvegetation and reclamation process would, however, reduce the significance of these impacts but not to below a level of significance. As indicated previously, overriding considerations would be required. 4.4 TRAFFIC Resolution Iqo. 90-163 Page 9 MITIGATION MONITORING AND REPORTING PROGRAM Completion of an access road built tO public road standards to carry truck traffic in/out of the proposed project site to thc north within two years of project approval would be a condition of thc Conditional Usc Permit. ANALYSIS OF SIGNIFICANCE The proposed project expects to generate approximately 886 daily trips by heavy trucks for a worst case scenario. With completion of an internal road to handle heavy truck traffic, impacts relating to traffic generated by the expanded plant operation would be considered at a level below significance. In the long term, most of the streets in the project vicinity will operate at LOS D or better, which is a goal for the City of Poway for long range plamzing. Some sections of Poway Road and Pomcrado Road will operate at less than desirable levels of service. Under short term conditions, the intersection of Poway Road with Pomerado Road is expected to operate at LOS D, which is a lcss than desirable level of service. Since.thc opening of thc South Poway Parkway (Alternative SA) is expected to change the regional traffic patterns in thc area, thc LOS for this intersection, under long term conditions, was not calculated. Thc increase in traffic generated by CalMat - Poway is not significant on a project-level; however, it does contribute incrementally to an already congested condition. Resolution No. ~0-163 4.5 NOISE Page 10 ; MITIGATION MONITORING AND REPORTING PROGRAM Potentially significant noise impacts associated with normal operation of the facility have been identified. However, an additional acoustical analysis will be performed to determine exact sources and levels of noise, based on specific layout and design of thc expanded processing plant site. Once this analysis has been performed, a comprehensive monitoring and reporting program can be implemented by a Mitigation Monitoring Coordinator who will ensure that proper, normal operating hours and appropriate noise lcvcls mcct all city rcquircmcnts. Periodic monitoring will be conducted by tile Coordinator. As a condition of approval of the CUP, a detailed acoustical report will be required to determine thc size o£ tile acoustical barrier (i.e., berm and wall). It is anticipated that up to a ten foot barrier will be required. The exact siting m~d height will be identified in tile acoustical study. ANALYSIS OF SIGNIFICANCE If tile mitigation measures suggested in the acoustical report (siting of machinery and stockpiles, construction of a noise barrier, and using flashing strobes during twilight hours and night usc of equipment back-up alarms) and in this document arc implemented as conditions of thc CUP, then potential noise impacts would be mitigated to a level below significance. 4.6 AIR QUALITY Reso'lut'ior, Ho. ~0-163 Page 11 MITIGATION MONITORING AND REPORTING PROGILAM Although thc City of Poway is thc lead agency for thc proposed project, responsibility for aggressively pursuing an active monitoring and reporting program would rest with cooperation of the facility operators and thc San Diego APED. Numcrous alternatives exist to monitor compliance of thc operation of thc facility. To a large degree thc permitting process establishes some form of controls and reporting means. A qualified APCD staff member would conduct site inspections during initial implementation of the proposed expansion. Eka-m-cottectcd--at--the-cto~e~t-monitohng stations .(I(-carny-lV~ and--E~condidcC)-would--bc an~tyzcd-~or suddca or continuous charrgc~-in-basctinc-d-ata-ovcr'"timc: CalMat will be required to cease operations for processing and extraction during dust episode alerts, ,~'uNALYSIS OF SIGNIFICANCE Though some unavoidable, adverse impacts are associated with the operation o£ this type of facility, no significant impacts can be expected with respect to basin air quality, if the above mentioned nfitigation recommendations are fully and actively implemented. UTILITIES Resolution No. 90-163 Page 12 MITIGATION MONITORING AND REPORTING Water To ensure that impacts to water quality and quantity arc reduced to levels below significance, RWQCB will specify a formal monitoring and reporting program as conditions to issuance of a Waste Discharge permit. Water quality monitoring and reporting will be required, as well as technical reports concerning the quantity and quality of any waste discharge, to assure RWQCB requirements have been met. The City will review thc report as a part of their annual review of the Conditional Use Permit (CUP). No significant impacts were identified. Should CalMat choose to utilize natural gas, written notification from SDG&E stating thai adequate itffrastructure is available to service the needs of the CalMat-Poway facility must be made prior to approval of CUP. ANALYSIS OF SIGNIFICANCE Water Impacts to water supply can be mitigated to below a level of significance by incorporation of the above mentioned mitigation program. Eneri..W. Thc lack of adequate infrastructure to service thc cncrgy demands of thc proposed expansion project is.considered to be a significant but mitigable impact. Provision of right-of-way casements and a gas line with the capacity to transport 12 million BTU/hr of fuel would mitigate these impacts to a level below significance should thc usc of propane or alternative fuel source not be used. The expansion o£ the facility to increase the amount of aggregate to be mined and to add thc asphaltic concrete projection element would contribute to the increased use of non-retrievable natural resources. Resolution No. 90-163 Page 13 CANDIDATE FINDINGS FOR THE CALMAT-POWAY FINAL SEIR EXHIBIT B CANDIDATE FINDINGS FOR THE CALMAT- POWAY FINAL SEIR Resolution No. 90-163 Page 14 The following findings are made relative to the conclusions of the Final Environmental Impact Report (EIR) for the CalMat-Poway project. The project involves the expansion of the current operation from 83 acres to a total of 166 acres. CalMat proposes to construct a private access road to divert truck traffic from Beeler Canyon and Creek roads per recommended mitigation for expansion of aggregate extraction in the South Poway Planned Community EIR. Through negotiations with City staff in the winter of 1989-90, CalMat agreed to construct the access road to public road standards as part of the expansion project. The expanded site will contain primary and secondary processing facilities which allow production of a full range of construction aggregate, road base and fill material. A ready-mixed concrete batch plant will continue operations, along with an asphaltic concrete and cement-treated base plant. To expand the site, the City of Poway will need to approve a Conditional Use Permit because CalMat's Special Use Permit P73-130M3W issued by the County of San Diego, prior to the City of Poway's incorporation will expire in October 1991; as well as approval of the Reclamation Plan. These findings are made pursuant to Section 21081 of the California Public Resources Code and Sections 15091 and 15092 of the California Administrative Code. FINDINGS mo The City of Poway, as lead agency and decision maker, having reviewed and considered the information contained in the Final EIR for the project and the public record, finds, pursuant to CEQA and CEQA State Guidelines, that changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR with respect to the areas of (1) biological resources, (2) land use, (3) aesthetics/landform alteration, (4) traffic, (5) noise, (6) air quality, and (7) utilities. Specifically, the City of Poway makes the following findings with respect to the identified significant environmental effects of the project: With respect to biological resources (EIR, pg. 4-1), the proposed project involves the expected loss of all of the site's breeding California gnatcatchers (a minimum of four pair), all of the sensitive Diegan coastal sage scrub (71 acres), Southern California grassland (10 acres), chamise chaparral (8 acres), and the combined loss of all the site's other sensitive species. These losses would be considered regionally significant adverse impacts of the proposed project both individually and in a cumulative sense. There are feasible mitigation measures which would reduce impacts to below a level of significance; however, the applicant has determined that Resolution No. 90-163 Page 15 these measures are not feasible. The following mitigation measures are incorporated into the project but do not reduce biological resources impacts to below a level of significance. Overriding considerations per the California Environmental Quality Act (CEQA) would need to be developed for the City Council action in the event the City Council approved a project. The following mitigation measures should be incorporated into the resolution for the project. a. A "spring survey" would be conducted in April through June to assess the status and distribution of the following sensitive species which are potentially present on-site: San Diego thorn-mint, Orcutt's brodiaea, San Diego goldenstar, California adder's-tongue fern, and variegated dudleya. All but the last of these would occur in the Southern California grassland or adjacent areas. Variegated dudleya could occur in dry diegan coastal sage scrub habitat. These are significant species, and the presence of any of these in substantial numbers would constitute a regionally important biological resource of this site, requiring mitigation through a supplement to this subsequent EIR. No disturbance of the spring time survey site shall be allowed until completion of the survey and further environmental review, if any. b. Impacts to the on-site riparian scrub habitat would be avoided by all grading operations. An open space easement would be designated on the CUP. If inadvertent impacts occur, there would be mitigation on-site through the development of a wetland mitigation plan. Such a plan should require full mitigation of wetland losses which result from implementation of this project. Such a plan would be prepared by a qualified biologist familiar with such programs, working in concert with a revegetation specialist or certified landscape architect. A five-year monitoring program would also be required. c. Impacts to on-site diegan coastal sage scrub vegetation would be partially mitigated by the development of a diegan coastal sage Scrub Habitat Restoration Plan, using manufactured slopes areas which would be prepared for this purpose following the completion of extraction activities. This will be incorporated into the restoration plan. Additionally, to ensure success there should be long term biological monitoring, including the preparation of status reports to be reviewed by the City annually for a minimum of ten years. Such a plan should be prepared by a qualified biologist familiar with such programs, working in concert with a revegetation specialist or certified landscape architect. d. Off-site mitigation to partially compensate for the loss of the site's Southern California Grassland could be developed in the form of habitat restoration and/or enhancement. This would require the 2 Resolution No. 90-163 Page 16 eo identification of target areas, suitable for the establishment or restoration of a diverse native grassland. South Poway still contains several large areas of grassland habitat which could be augmented and/or upgraded through the development of a native grassland restoration project. The specifics of such a plan are beyond the scope of the biological report prepared for the EIR; however, it would require, at a minimum (a) off-site restoration or enhancement area identification; (b) the preparation of a precise planting program, specifying species and quantities to be used (based on indigenous taxa and diversity ratios); (c) possible specimen, soil and/or inoculum salvaging from the existing grassland; (d) a complete soil preparation plan; (e) maintenance, including irrigation requirements, the control of exotic annuals, etc; and .(f) long-term biological monitoring, including the preparation of status reports to be reviewed by the City annually for a minimum of five years. Such a plan should be prepared by a qualified biologist familiar with such programs, working in concert with a revegetation specialist or certified landscape architect. The City of Poway is currently conducting a California gnatcatcher study. The goal of this study is to provide direction to the City as to the appropriate measures necessary for the preservation and enhancement of gnatcatcher habitat. CalMat should contribute financially for the acquisition of lands targeted by the study for preservation. This mitigation measure would be a condition of the CUP. The amount of financial contribution will be determined by the City staff. Funds contributed will be specifically used for the acquisition of land for enhancement or preservation of gnatcatcher habitat. With respect to land u~e (EIR, pg. 4-15), the proposed project involves the use of the site to mine aggregate in keeping with the Mineral Resource Zone-2 (MRZ-2) for aggregate by the State of California Department of Conservation, Division of Mines and Geology. The project is generally in conformance with the extraction goals of the South Poway Planned Community regulations and no significant land use impacts have been identified. Regarding adjacent land use impacts, significant impacts would be mitigated to a level below significance with the incorporation of the following measure: ao Closing Beeler Canyon Road to all heavy truck traffic entering and leaving the CalMat-Poway operation by providing an internal road built to public road standards with access via Kirkham Road within 15 months of approval of expansion plans. This measure will be a condition of approval of the CUP. Resolution No. 90-163 Page 17 o With respect to aesthetics/landform alteration (EIR, 4-22), the proposed project involves excavation of the entire approximately 166-acre site. The final landform will include an 88-acre pad at the base of the aligned slopes, a maximum 2:1 slope of approximately 300 feet, and several flat pads at the top of the slopes. Because the topography range is prominent and currently vacant and because the extraction process results in removal of the landform, impacts to the landform of the proposed project are considered significant. The following mitigation measures have been recommended to reduce impacts but not to below a level of significance (Overriding considerations per CEQA would be required): ao Concurrent reclamation restricting the disturbance area and revegetating disturbed areas of the slopes before mining begins in another area. Co do Revegetation to include native and natural plant species which would blend with existing vegetation. Undulating the slopes following the original contours of the landform, rather than one large pad. Establish transition areas or buffer areas to blend the graded areas with native areas. Benching of slopes to ensure long-term stability and minimize slope erosion. On-site landscape screening of existing and proposed operations which block views from nearby sensitive receptors. With respect to traffic. (EIR, pg. 4-33), the proposed project would involve the routing of heavy truck traffic (incoming and outgoing) onto a private internal road built to public road standards. The total number of truck trips associated with the project expansion is expected to be 886 trips. Impacts relating to traffic generated by the expanded plant operation would be considered at a level below significance; however, it does contribute incrementally to an already congested regional condition. The following measure has been incorporated into the project design which would reduce impacts to below a level of significance. Completion of an access road to carry truck traffic in/out of the proposed project site to Kirkham Road within 15 months of project approval would be a condition of the CUP. With respect to noise (EIR, pg. 4-41), the project involves the increase in noise levels resulting from operation of on-site equipment and truck traffic along the internal access road. These potentially significant noise impacts R~so'lution ho. ~,0-163 Page 18 o would be reduced to a level below significance with the provision of the following mitigation measures incorporated into the project design: ao Conduct an additional acoustical analysis to determine exact sources and levels of noise, based upon specific layout and design of the expanded processing plant site. A detailed acoustical report be required as a condition of the CUP to determine the location and height of acoustical barrier (i.e., berm and wall) along the access road. Co All production operations shall be limited to the time period set in the CUP. do The processing plant layout would be evaluated in terms of maximizing the use of storage and surge piles to shield noisy equipment such as secondary crushers and vibrating screens. In addition, the secondary crusher would be sheltered in such a way as to create a pit in which noise will be 'funneled upward instead of radiating outward. Back-up alarms on loaders, dozers, water trucks and other mobile equipment would be turned off during twilight hours and replaced with a flashing strobe as authorized by MSHA to minimize the intrusive noise from such alarms. With respect to air quality (EIR, pg. 4-47), the project involves the increase in fugitive emissions (primarily dust) and traffic generated emissions. These impacts are considered to be unavoidable adverse impacts associated with the operation of an aggregate extraction and processing facility which can be mitigated to below a level of significance. The following mitigation measures have been incorporated into the project design and identified which would reduce impacts to below a level of significance: ao Authority to construct and permits to operate must be obtained from the San Diego APCD that satisfy the air district that all available measures have been taken to minimize the project air quality impact. bo Annual monitoring of emissions will be done by the APCD to ensure that the plant operates as designed. c. Paving and daily wet sweeping would be required on the access road. do Conveying, screening and crushing operations will require adequate water at transfer points for dust control. Resolul:ion No. 90-163 Page 19 eo Frequent watering of the haul routes will be required to limit dust emissions from the equipment moving on unpaved in-plant surfaces. An extensive planting program along the access road from the site would include both a fast-growing shrub component such as oleander as well as a dense row of trees to act as a windbreak, confining dust and sand particles to within the site during Santa Ana wind conditions from the east/northeast. go A baghouse will be required for the asphalt plant to control particulate emissions as well as blue smoke control of hydrocarbon vapors from the asphalt heater/drier and storage silos. ho Implementation of effective controls on process emissions using best available technology to prevent the formation of any significant air quality effects from normal plant operations. Implementation of an aggressive housekeeping program to control fugitive dust emissions (e.g., Runoff and Sedimentation Control Plan). Re-routing haul traffic through industrial areas and along the proposed new private access road, away from existing residential developments. With respect to utilities (EIR, pg. 4-63), the project involves the estimated water requirement of approximately 381 acre-feet per year (1.66 acre-feet per day) which was determined to be significant but mitigable to below a level of significance. No significant impacts were identified for energy consumption; therefore, no mitigation is required. The incorporation of the following water conservation measures would reduce impacts to below a level of significance. A formal Runoff and Sedimentation Control plan be developed to assure that excessive erosion and sedimentation would not occur which could adversely affect Beeler Creek. bo A technical study be conducted to determine the maximum utilization of reclaimed water for aggregate production. Dual piping would be added to the project site upon expansion to ensure facilities are in place once reclaimed water becomes available. This would minimize potable water use. Reclaimed water would be used for all mining operation and for on-site dust control. do Environmentally-safe surfactants are mixed with water used to spray roads to control dust to maximize effectiveness and reduce water consumption. Resolution No. 9d-163 Page 20 Bo Co eo Aggregate plant process water would be clarified by means of settling ponds and recycled for continued use. Rainfall runoff from the plant site would be directed into a sedimentation pond so that it can be used for dust control purposes. go Mixer truck cleanout water would be directed into a sump for re- use by the plant. ho The floor of the pit would be graded to direct water to an erosion sump/containment basin at the lower end of the pit. The City of Poway, as lead agency and decision maker, having reviewed and considered the information contained in the final subsequent EIR for the project and the public records, finds that there are changes or alterations to the project which avoid or substantially lessen the significant environmental impacts, specifically, implementation of the mitigation measures detailed above. The City of Poway, as lead agency and decision maker, having reviewed and considered the information contained in the final subsequent EIR for the project and the public record, finds there are no specific economic, social, or other considerations which make infeasible the mitigation measures in the EIR. With regards to the project alternatives, several issues may render any part or all of each alternative(s) infeasible for reasons included below: With regards to the No Project Alternative, 'the on-going extractive and processing operations at the present site (68 acres) would continue until expiration of their SUP in October 1990 at which time all further quarrying activities would end, and the site would be reclaimed in accordance with the SUP. This alternative would eliminate the significant adverse unmitigable impacts to biology and aesthetics/landform alteration. In addition, significant but mitigable impacts to land use, traffic, noise, air quality, and utilities would not occur. This alternative would have the following additional impacts: ao Adoption of this alternative would not provide a local source of aggregate for nearby construction, thus requiring construction projects to travel greater distances to obtain this resource. bo Utilization of the present CalMat facility and the surrounding area of enlarged extraction potential, as indicated in the South Poway Planned Community Land Use Plan, and as set forth as partial mitigation for the loss of regionally-significant mineral resources resulting from industrial development, would not occur. Resolution No. 90-163 Page 21 o This alternative would also not meet the following objective; maximize the recovery of the on-site regionally-significant mineral resource. With regards to the Limited-Scale Alternatives there are two scenarios including 1) continued operation within the existing boundaries with no additional uses, and 2) expanded extraction operations into the 166 total acres without an asphaltic plant on-site. Scenario one (1) would reduce the magnitude of impacts to biology and aesthetics/landform alteration. This alternative would result in an incremental reduction in impacts to noise, air quality and utilities. This alternative would not meet the objectives of CalMat for the following reasons: This alternative would not meet the project's objectives of providing processing facilities for asphaltic concrete and expansion to include the additional 83 acres. The adoption of this alternative does not meet the intent of the partial mitigation requirement for the loss of regionally-significant mineral resources resulting from industrial development. Scenario two (2) would result in an incremental reduction in air quality impacts as a result of no asphaltic concrete plant. 'Impacts to land use, traffic, noise and utilities would be similar to the proposed project. Impacts to biology and aesthetics/land form alteration would be adverse and unmitigable. This alternative would not meet the objectives of CalMat for the following reasons: a. This alternative does not significantly reduce the level of impacts. This alternative would not meet the project's objective of providing processing facilities for asphaltic concrete. With respect to Alternative Siting. three sites were evaluated. alternative sites would have the following additional impacts: These This alternative would not meet the following objectives of the proposed project: Extend the existing SUP as a CUP so that CalMat-Poway could continue extraction in the South Poway Planned Community. Resolution No. 90-163 Page 22 Provide for the expansion of the site as partial mitigation for the loss of this mineral resource made unavailable by the development of the Pomerado Business Park. The increased hauling distance and cost of these sites would make it economically infeasible to serve CalMat-Poway's 1-15 corridor marketing area which extends from the Kearny Mesa area to Escondido. With respect to Alternative Use-Residential Development, this alternative would allow for reclamation of the site upon expiration of SUP in October 1990 to be developed as a low density residential community. The site would experience typical air quality, biological, land use, traffic, noise, aesthetics/landform alteration, and utilities/public services impacts associated with residential use.
