(Stantec) is pleased to submit this Second Revised Remedial Action Plan (RAP) for pesticide-impacted soils identified on the vacant parcels located on the southwest corner of the intersection of Valley Street and Oak Avenue, within the City of Corlsbad, County of San Diego, California, hereafter referred to as the "Site" (see Figure 1). Stantec submitted a RAP for the Site on July 6, 2012, to the Son Diego County Department of Environmental Health - Voluntary Assistance Program (DEH) for review and approval. On August 23, 2013 DEH provided a review letter to the RAP (attached as Appendix C). The review letter requested five (5) items to be provided to support the RAP prior to approval. These five (5) items included the following: 1. Submit copies of the reports for both Phase II soil investigations to GeoTracker and provide paper copies to DEH. 2. DEH recommends performing additional soil sampling and COP testing at the ^ property for the depth interval between 1.0 and 2.5 feet. Having toxaphene n concentrations data from this inten/al upfront would be more cost-effective than interactive excavation based conformation sample results (i.e., no delay in operations while awaiting laboratory reports). The data would also allow more ' ' accurate estimates of the volume of impacted material subject to reburiol. DEH suggests collecting the additional samples at the locations where toxaphene concentrations exceed its CHHSL. 3. DEH requires a minimum 7-foot cap between the toxaphene-impacted material and final grade. Please revise the RAP to address this requirement. 4. Dust monitoring and sampling procedures to be employed at the property during soil excavation, stockpiling, reburiol, and fill placement activities shall be in M» ill 5 County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California 4. Dust monitoring and sampling procedures to be employed at the property during soil excavation, stockpiling, reburiol, and fill placement activities shall be in accordance with the procedures approved by the DEH for the City Ventures property at 1264 Lake Drive in Encinitas (DEH, July 24,3013).' 5. Provide a brief description of the storm water best management practices (BMPs) for the remedial activities. The description shall be accompanied by a mop that uses symbols for specific BMPs (e.g., straw rolls, heavy equipment decontamination, and detenfion basins) and shows where they would be implemented on the property. Stantec submitted o Revised RAP for review to the DEH that included the five items referenced above doted November 2013. On December 23, 2013, DEH provided a review letter for the revised RAP referenced above (attached in Appendix C). That review letter requested that the following additional items be included in a second revised RAP. 1. Collect additional samples in the northwest and southwest areas of the Site indicated on Figure 2 of the Revised RAP. DEH esfimotes that 8 to 10 additional sample locafions ore needed to provide coverage comparable to that for the remainder of the Site. Or, excavate the entire Site to one foot depth. Stantec chose to proceed with additional sampling. 2. Please submit a second revised RAP and Community Health and Safety Plan (CHSP) that incorporates the air monitoring and sampling protocols in the following report, which was prepared for City Ventures property at 1264 Lake Drive, Encinitas (DEH Cose #39744-001). This Third Revised RAP is being submitted to the DEH and also to the City of Carisbod Development Services for approval. This Second Revised RAP addresses the two new comments referenced above and some minor edits submitted by e-mail to Stantec on January 15, 2014. BACKGROUND INFORMATION The Site consists of two parcels of agricultural land totaling approximately 3.89 acres located on the southwest corner of Valley Street and Oak Avenue, within the City of Corlsbod, County of San Diego, California. Phase I ESA Stantec completed a Phase I ESA for the subject property and issued a report of findings on January 27, 2012. The historic aerial photographs indicated that the Site was historically used for agricultural purposes from prior to 1939 unfil recently. Due to the historical agricultural use, Stantec recommended performing a Phase II ESA to evaluate the concentrations of organochlorine pesticides and arsenic in soils at the Site. County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California Phase II ESA Stantec completed a Phase II ESA on the subject property on March 30, 2012. That Phase II ESA was designed to evaluate whether residual organochlorine pesticides and arsenic were present at concentrations of concern. The Phase II ESA identified the presence of the organochlorine pesficide toxaphene, in shallow soil, at concentrations above current California Human Health Screening Levels (CHHSLs) for residential use. No other organochlorine pesficide or arsenic was detected above levels of concern. The lateral and vertical limits of the toxaphene in soil were not defined by the completed assessment. Stantec recommended that further assessment be completed to more accurately assess the lateral and vertical limits of this organochlorine pesticide and confirm that toxaphene was the only compound of concern. Additional Subsurface Investigation Stantec conducted the recommended additional Phase II ESA at the Site on May 14 and 15, 2012. The additional Phase II ESA consisted of a total of sixteen (16) hand auger borings located across the Site in order to further delineate the pesticide-impacted soil identified by the previous Phase II ESA (see Figure 2). Chemical analysis of all analyzed shallow soil samples reported the presence of organochlorine pesficides, except at locafion HA-17. The detected organochlorine pesticides included 4,4'-DDE, 4,4'-DDT, and toxaphene. Toxaphene was the only organochlorine pesticide detected above the U.S. EPA Regional Screening Level (RSL) of 0.44 mg/kg, and the CHHSL of 0.46 mg/kg for residential uses for this compound. The peak concentrofion of toxaphene was 2.1 mg/kg located in HA-10 at the 0.5 to 1 foot below ground surface ("bgs") interval. Further, toxaphene was only detected above the RSL and CHHSL in the samples collected from 0.5 to 1.0 feet bgs. Samples collected from 2.5 to 3.0 feet bgs detected no toxaphene or any other organochlorine pesticides above their RSL or CHHSL. Stantec esfimated that the area containing the elevated toxaphene concentrations is approximately 107,000 square feet in size. The collected data suggested on assumed average depth of 1.5 feet bgs where toxaphene may be present above the CHHSL and RSL. Based on the esfimated aerial distribution and an assumed 1.5 foot depth, the assumed volume of impacted soil was esfimated to be approximately 6,000 cubic yards. Second Additional Subsurface Investiaation as Recommended bv DEH in Item 2 At the recommendation of DEH, Stantec conducted an addifional Phase II ESA at the Site on September 26, 2013 to satisfy item 2 of the review letter. Stantec collected soil samples at the intermediate interval (1.5 to 2 feet bgs) between to the shallow and deep samples collected during the first two field investigations at locations that reported levels of County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California toxaphene above CHHSLs. This addifional Phase II ESA consisted of a total of sixteen (16) hand auger borings located adjacent to the boring locafions that reported toxaphene above CHHSLs in order to further delineate the verficol extent of pesficide-impocted soil (see Figure 2). Chemical analysis of all analyzed soil samples reported no toxaphene above laboratory reporting limits with the exception of three samples. In those three samples, no toxaphene was detected above the U.S. EPA Regional Screening Level (RSL) of 0.44 mg/kg, or the CHHSL of 0.46 mg/kg for residential uses for this compound. The sample locafions ore indicated on Figure 2 and the laborator/ results contained on Table 1. Analytical results ore contained in Appendix B. Based on the additional sampling, toxaphene impact above CHHSLs is limited to the top foot of soil at the Site. Stantec esfimates that the area containing the elevated toxaphene concentrations is approximately 107,000 square feet in size. The collected data suggests on assumed overage depth of 1 foot bgs where toxaphene may be present above the CHHSL and RSL. Based on the esfimated aerial distribufion and on assumed 1 foot depth, the revised volume of toxaphene impacted soil is esfimated to be approximately 4,000 cubic yards. Third Additional Subsurface Investigation as Recommended bv DEH in new Item 1 At the recommendation of DEH, Stantec conducted a third Phase II ESA at the Site on January 8, 2014 to satisfy new item 1 listed above. Stantec collected soil samples in the northwestern and western porfion of the property. Soil samples were collected from depths of 0.5 to 1.0 feet and 1.5 to 2.0 feet in depth at each location. This additional Phase II ESA consisted of a total of ten (10) hand auger borings to increase sampling density in that portion of the Site (see Figure 2 for samples H-1 through H-10). Chemical analysis of soil samples reported toxaphene above the U.S. EPA Regional Screening Level (RSL) of 0.44 mg/kg in seven (7) of the shallow samples and four (4) of the deep samples. One of the deep samples was below the CHHSL of 0.46 mg/kg for residential uses for this compound. The sample locations ore indicated on Figure 2 and the laboratory results contained on Table 1. Analytical results ore contained in Appendix B. Stantec is not recommending any further vertical assessment at the three locations where the 2.0 foot sample contained impact above the CHHSL for toxaphene. At those locations verification sampling during remedial excavation discussed below will be used to verify impact depths and that removals are accomplished to Site clean-up levels. Based on the additional sampling, toxaphene impact above CHHSLs is limited to the top foot of soil at the Site in most areas and there are three small pockets where soil is County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California impacted to 2 feet bgs. Stantec estimates that the area containing the elevated toxaphene concentrations is approximately 145,000 square feet in size. Based on the estimated aerial distribution and on assumed 1 foot depth across most of the Site and 2 foot depth in three limited areas, the revised volume of toxaphene impacted soil is estimated to be approximately 6,000 cubic yards. Remedial Options Based on the elevated concentrations of toxaphene, the DEH requires management of the material prior to approving Site development. The two best options for managing the material, based on ability to obtain approval and on cost, are (1) on-site burial and (2) off-site disposal. The City of Carlsbad has agreed to abide by DEH directives in regard to the potential remedial options. Based on the volume of impacted soil of the Site, on-site burial is by forthe more cost effective remedial option. Therefore, the following work plan describes the proposed remediation at the Site via option (1). SITE CONDITIONS Geology and Hydrogeology The Site is located within the Peninsular Ranges Geomorphic Province characterized by northwest-southeast trending mountains and valleys strectching from the San Gabriel and Son Bernardino Mountains on the north and extending southward into Mexico (CGS, 2002). The area is underiain by Mesozoic igneous and metamorphic rocks to the east and a dissected coastal plain underiain by Cenozoic sediments to the west. The regional surficial geology is described as Cenozoic Marine Sedimentary Deposits consisting of older alluvium and dissected alluvial fan deposits. Surficial soils ore comprised of interbedded silts, and cloys (CDMG, 1965). The Site is located at on elevation of approximately 160 feet above mean sea level (amsl), south of the Bueno Vista Lagoon and north of the Agua Hedionda Lagoon. Surface topography in the vicinity of the Site slopes south southwest. Groundwater flow direcfion is anticipated to the southwest towards the Pacific Ocean. According to Environmental Data Resources (EDR), the Site is not located within either the 100 year or the 500 year fiood zone. Groundwater in the vicinity of the Site generally flows to the southwest towards the Pacific Ocean. According to the State Water Resources Control Board's (SWRCB) GeoTracker Database, depth to groundwater has been measured at a range of 10 to 13 feet below ground surface (bgs) in a monitoring well (lost reported during the Third Quarter 2011 monitoring event) located approximately half a mile southwest of the Site at the intersection of Corlsbad Village Drive and the Southbound 1-5 on-romp (SWRCB, 2011). Based on discussions with Ms. Carol Fenner there is about 80 feet difference in elevation County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California between the site referenced above and the subject Site. Ms. Fenner expects the depth to groundwater to be much greater than 13 feet below ground surface. Based on that information, there does not appear to be a limitation on the burial depth at the Site. Like most of California, the Site is located in a seismically active area. The nearest active fault is the Rose Canyon Fault, located approximately 4 miles southwest of the Site (CDMG, 2010). This fault is capable of generating significant seismic events (greater than 5.0 magnitudes). The site is not located within on Alquist Priolo Special Studies Zone (CDMG, 2012). PROPOSED ON-SITE IMPACTED SOIL MANAGEMENT Standards All work will be performed in accordance with CSDDEH requirements and protocols under the supervision of a California licensed engineer or professional geologist. Field activities will be conducted in accordance with o site-specific Health and Safety Plan and a Community Health and Safety Plan (attached to this document). Stantec proposes that during the Site grading, the soil impacted with toxaphene above the site cleanup levels (CHHSLs) will be excavated and stockpiled on-site. Figure 2 provides the locations where exisfing test results indicate the toxaphene exists above the proposed Site cleanup level. For the purposes of this RAP, and to be consistent with prior remedial action under the oversight of the DEH, the proposed Site cleanup level is the CHHSL for toxaphene at 0.46 mg/kg. The depth and lateral extent of the remedial excavation has been estimated by the previous site assessment data. A tentative Site grading plan has been developed based on this data and included as Figure 3 attached. Dust Mitigation and Monitorinq in Response to Item 4 During movement of impacted soil, efforts will be mode to prevent generation and migration of dust. Prior to movement of soil, the surface will be watered to ensure that moisture penetrates into the soil that is to be excavated. During the movement of soil, large amounts of water will also be used to help prevent dust from being generated. If the sustained wind speed exceeds 13 miles per hour for over 30 minutes, grading activities will cease until the wind speed subsides to levels below 13 miles per hour. Wind speed will be recorded, as well as direction, during the course of the working hours. A weather station will be positioned on the Site that will record wind speed, direction, and temperature. That information will be used to verify dust monitors referenced below ore properly positioned and grading termination is accurately enforced. County of Son Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California Stantec has been requested by CSDDEH to follow dust monitoring procedures developed and implemented on other pesticide mitigation projects in their county. Stantec was provided a copy of a document developed by GeoSoils, Inc. Stantec has used that document below and adjusted the procedures as necessary, but largely used the document as written by GeoSoils, Inc. Stantec is not aware of regulatory action levels for short term community exposure to airborne organochlorine pesticides such as toxaphene. The United States Environmental Protection Agency (US EPA) has developed Regional Screening Levels (RSLs), which were developed to replace and update the information in the document entitled Region 9 Preliminary Remediation Goals (PRG) 2002 Update, doted November 1, 2002, and revised November 2010. The designated RSL values ore for airborne contaminants in a residential land use scenario. These designated values, however, assume that the resident is exposed to airborne concentrations of the contaminant for 24 hours o day, 7 days a week, and 365 days a year. Accordingly, the RSL values would be very conservative to use for the anticipated short term exposures associated with organochlorine pesticide bearing soil dust generated from the proposed excavation and disposal activities. Based on other studies completed in the area, GeoSoil, Inc. calculated an airborne contaminant concentration limit or modified RSL for toxaphene based on a more realistic exposure scenario of 8 hours a day, 7 days a week, and a maximum of 35 days of exposure, which was in the opinion of GeoSoils, Inc. very conservative for on exposure scenario. This limited-term exposure scenario assumes excavation, grading, and soil disposal activities associated with the disposal of toxaphene impacted soil are completed within a total of 35 days of work. Based on the project being discussed herein the duration is estimated to be less than 10 days, so these values ore even more conservative. The moditied Site-specific RSL were calculated by GeoSoil, Inc. using Site-specific assumptions and the RSL formula used by the US EPA. This formula is used for the calculation of RSLs for airborne concentrations of contaminants corresponding to a typical de minimis theoretical excess lifetime cancer risk of one in a million (lE-06). This Site-specific RSL value is presented on the following table: County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California MODIFIED SINGLE TOXAPHENE RSL (ug/m^ MODIFIED CUMULATIVE ) TOXAPHENE RSL (uglm" 6.91 ^ 3.45 *The final RSL was further adjusted by dividing the RSL by a factor of two to account for cumulative cancer risks. 1 RSL = Regional Screening Level ug/m^= Micrograms per cubic meter Perimeter oir monitoring will be conducted at the Site utilizing low-volume sampling pumps, calibrated to a doily flow rote of approximately one liter per minute. The low-volume sampling pump will pump air through a filter/solid sorbent tube, which will be analyzed for toxophe. Stantec will use the sampling procedure document by the National Institute of Occupafional Safety and Health (NIO Method 5600). Analytical laboratory tesfing will be completed at a California certified laboratory within 24 hours of obtaining the sample. Prior to conducting excavation and soil burial activities at the Site, Stantec will collect perimeter air monitoring samples initially at locations based on predominant wind patterns at the Site, and surrounding residential development. Prevailing wind directions will be based on a Site specific weather station installed at the Site. In addifion, Stantec will obtain regional data from the local and nation weather information web-sites. Samples will be obtained both on the perimeter of the Site and near the excavation and stockpile/reuse areas to evaluate background airborne concentrations of toxaphene in general accordance with NIOSH Method 5600. The approximate locations of the proposed oir monitoring stations will be determine when the wind directions ore determined and submitted to the CSDDEH prior to placement for their approval. During the initial three or four days of excavation and soil stockpiling and burial activities, perimeter air monitoring samples will be collected from the designated locations to be determined. The air samples will be analyzed for toxaphene in general gccordgnce with NIOSH Test Method 5600 to assess potential exposure to the surrounding community. In addition, dust meters will also be placed at the air monitoring stations to measure total dust generated from the construction activities. Based on the results of the oir monitoring for toxaphene and the total dust readings during the initial days of excavation and soil disposal activities, a toxicologist will evaluate the collected data, and statistically assess whether or not there is a correlation between concentrations of toxaphene and total dust measurements. If o direct correlation is established, and action level for toxaphene will be established based on the relationship of the total dust measured as total particulate concentrations in air to toxaphene concentrations. The established action level will be total dust measurement at which toxaphene concentrations are below the moditied RSL. As the excavation and disposal operations proceed, Stantec will collect dust meter readings at the metering stations every hour during earthwork operations. The results of the dust meter readings will be compared to the established action levels and the County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California National Ambient Air Quality Standards (NAAQS) for particulate matter (PMIO) of 150 3 ug/m . The locations of the dust meters, the time of sampling, and range of measured concentrations will be recorded in a doily log by Stantec field personnel. It total dust readings exceed the lowest of the established acfion levels or NAAQS standards, dust suppression efforts at the Site will be increased or construction operations will be stopped. The CSDDEH Project Manager will be notified of air sampling exceedances the next business day. The notifications will include the action token to abate the exceedance and follow-up sampling must be conducted and reported to ensure abatement activities were successful. Perimeter oir sampling will be conducted at_the six proposed locations once during the remedial project to assess the relationship between total dust and toxaphene. In addition, wind direction and speed monitoring will be conducted and documented using a portable weather station. The perimeter air monitoring will be performed until confirmation samples indicate that the mitigation criteria hove been met and the placement of a clean soil cap overlying the toxaphene impacted soil has been constructed. The air samples collected from the Site will be placed on hold and maintained at zero degrees Celsius at the laboratory for 30 days after analysis in accordance with the method. Should public complaints regarding potential exposure be received and need to be further addressed, these samples would then remain valid for 30 days following collection if additional analysis is requested. If possible, the dust concentration from quantitive sampling events will also be reported by the laboratory. Stantec will meet with the developer and grading contractor to discuss the soil disposal plan, oir monitoring, sequencing, and duration of work. If any information changes that may impact perimeter air monitoring, the DEH will be contacted and on additional addendum to the Community Health and Safety Plan will be submitted to the DEH for approval. Excavation and Somplina The Site grading contractor will control how and where the pesticide-impacted soil is removed to the esfimated depths and lateral limits. As removals occur, Stantec will provide obsen/ations along with the site surveyor to verify removals. Representative soil samples will be collected from the base of the excavation to verify that toxaphene has been removed to the Site cleanup levels. Historical soil samples results will be used to guide the excavation depths in advance of verification sampling. Stantec proposes collecting a base sample every 50 foot on center or less (as needed in smaller areas) in the base of each excavation. Side wall samples will be collected on a frequency of one per 100 feet of side wall. Soil samples will be collected with a drive sampler into two (2) Inch diameter metal sleeves. The ends of the sleeves will be capped with a plastic cop and sealed with silicone tape. All samples will be placed into an iced cooler for transport to the laboratory for analysis. County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California Collected soil samples will be analyzed in o State of California certified laboratory. All samples will be analyzed for organochloride pesticides by EPA test method 8081. These results will be used to establish that the remedial excavation depths hove removed impact to the Site cleanup levels. Where results indicate that toxaphene exists above the Site cleanup level, additional excavation to greater depths will occur. After additional excavation, new verification samples will be collected to verify that removal has occurred to the Site cleanup level. Confirmation from DEH Once the impacted soil has been removed and stockpiled, the laboratory results will be provided to DEH. Once DEH has confirmed that it is satisfied that the toxaphene- impacted soil has been removed to the required Site cleanup level, the remedial excavation will be expanded for burial of the stockpiled impacted soil. The depth of these excavations will be determined based on the volume of soil to be placed. Based on the depth to groundwater reported by DEH burial depth is not limited on this Site. For practical grading purposes the depths ore not expected to exceed 30 feet, generating a minimum separation of 50 feet from assumed groundwater. Burial of Impacted Soil / Clean Fill Cop in Response to Item 3 The impacted soil will then be placed within the base of the excavation which will be located primarily beneath the roadway (below ufility depths) and, in the event that o larger excavation is needed, also below building footprints and front yards. See figure 4 for recommended burial locafions on the Site. The impacted soil will be covered with no less than seven (7) feet of clean soil in all burial locations. Cover soil will not contain pesticides above the Site cleanup level. In addition, the cover thickness will extend below the overiying ufility depths to ovoid future disturbances. Impacted soil will not be buried beneath backyards, in cose of future homeowner construction activities. See attached Figure 4 for placement locations on the tract. Figure 5 provides a typical cross section of the burial cells for the impacted soil. Geo-Fobric In all areas where the impacted soil is buried, a geo-fabric will be placed over the material to be used os o marker. This marker will allow any future construction worker to identify where the pesticide-impacted soil is located to avoid future contact. The burial cells will also be surveyed and a final location map developed to be attached to the deed and placed on reference at the city. Soil Handling Procedures / Protecting the Surrounding Environment While hgndling the toxophene-impgcted soil during excavafion, stockpiling, and backfilling operations, a monitoring program will be in place to control impacted soil County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California migration off-site via aerial suspension, stormwater run-off, or attachment to equipment leaving the property. Stantec proposes the following controls to minimize the spread of toxaphene off-site: • During excavafion and stockpiling activities, copious amounts of water must be applied to the soil in order to suppress dust particles from becoming oir-borne. Additionally, toxaphene-impacted soil must not be disturbed if winds exceed 13 miles per hour (mph). All stockpiled soils must be covered with heavy grade plastic sheets while water suppression is not employed, porficuloriy during non- working hours. • To reduce worker exposure to contaminated dust all heavy equipment should hove closed cabs with positive pressure fans or the operators should wear dust masks. • To ensure that impacted soil is not carried off-site, all vehicles and equipment should be inspected prior to exiting the Site. If significant amounts of soil ore trapped within the tires or under-corrioge of vehicles, the soil should be removed prior to the vehicle exifing the Site. During and at the end of each day any soil deposited on Oak Avenue or Valley Street outside the exit of the Site will be swept up and returned to the property for on-site management. • If site development is required during rainy periods, core should be token to minimize the negative effects. Educated judgment should be used to determine the significance of the potential rainfall event and how it might affect the remedial grading activities. If a significant rainfall event is anticipated or occurs during construction operations, necessary measures must be taken to minimize erosion of stockpiles and limit soil erosion from off-site migration. A Storm Water Pollution Prevention Plan (SWPPP) should be prepared if construction activities extend into winter months. In addition to actions token to mitigate the spread of toxaphene to the surrounding neighborhood, the following controls should be in place to ensure community safety and compliance with City ordinances: • The Site will be fenced and gated, limiting access to only those authorized. • Equipment operation times will be dictated by the City of Carisbod Zoning Ordinances. The Site is surrounding by residential neighborhoods. It is anticipated that noise may be on issue which will require some level of cooperation between the developer and the surrounding neighborhoods. • Given the size of the excavations, they will need to remain open overnight. Proper safety will need to be in place, such as safe side slope and at least one end open County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California to easy gccess into and out of the excavation. Efforts should be in place to backfill excavations as soon as possible otter completion. If not backfilled, excavations or the enfire site will be fenced off to prevent public access at the end of each work day. Imported Fill (If Anv) In the event that it is necessary to import soil to the Site to adjust Site elevafions, inspection of the potential borrow site will occur. That inspection will include a review of historic aerial photographs and document review to confirm that the Site has no history of agricultural use or other potential environmental impacts. If the site does not hove a history of agricultural use then soil samples will be collected to confirm the absence of pesticide impacts. If no impacts ore detected, that borrow site will be accepted for use. Verification of import sampling will be provided to DEH prior to deliver/ of any material to the Site. After the Site has been final graded, soil samples will be collected from the shallow subsurface soil on the building lots at o depth of 0 to 2 feet bgs and analyzed for residual pesficides using EPA Test Method 8081. Verificafion sample results from the surface will be used OS verification that no pesticide-impacted soil exists in the near surface soils on the Site. Stantec will compile all data collected from the field activities into a final report. That report will be forwarded to the CSDDEH and the city of Carisbod for site closure. The report will include all test results, mops, a narrative of Site activities necessary to understand and document the remedial activities. Storm Water Best Management Prgctices (BMPs) in Response to Item 5 Stantec has provided a copy of the BMP mop prepared by Huitt-Zollars, Inc. in Appendix D. COMMUNITY HEALTH AND SAFETY PLAN A site-specific Community Health and Safety Plan has been prepared for this project and is attached in Appendix A. The area surrounding the subject Site is an active urban environment. Traffic and associated site access controls will need to be enforced. It is anticipated that the Site will be fenced and access will be limited to authorized personnel only. Based on the contaminants of concern identified at the Site, the primary health and safety issue associated with the planned remedial excavation activities under this RAP will be the proper control of dust during Site grading activities. County of San Diego, Department of Environmental Health THIRD REVISED PESTICIDE REMEDIAL ACTION PLAN, Carlsbad, California The Community Health and Safety Plan provides guidance for the handling of known and unknown hazards that may be encountered at the Site, as well as provide guidance for a safe work environment for the public by: • Reducing community exposures to potential hazards and nuisances caused by Site work; • Promoting community awareness of the proposed remediation project; and • Monitoring and mitigating potential public hazards and nuisances caused by the Site work that may migrate off-site, including dust and noise. SITE-SPECIFIC HEALTH AND SAFETY PLAN A site-specific Health and Safety Plan has been prepared for this project and is attached in Appendix B.

The Community Health and Safety Plan is intended to minimize impact to the surrounding community and be protective of the health of the community during the remedial activities. Site Identification The Site is approximately 3.89 acres of currently undeveloped land located at the southwest corner of Oak Avenue and Valley Street, within the City of Carlsbad, California (the "Site"). Assessor parcel numbers associated with the Site ore 156-212-04-00 and 156- 212-05-00. The Site is in the process of being admitted to the County of San Diego Voluntary Assistance Program. The Site is proposed to be redeveloped as a multi-family residential property. Evaluation of Potential Publlc Exposure to Hazards The Site consists of approximately 3.89 acres of land, which was historically used for agricultural purposes. Three subsurface pesticide investigations have been conducted on the Site by Stantec, resulting in the collection of soil samples for the analysis of residual organochlorine pesticides. Laboratory analysis identified the presence of the organochlorine pesticide toxaphene at concentrations above the U.S. EPA Regional Screening Levels (RSLs) and California Human Health Screening Levels (CHHSLs) for soil to be used in a residential setting. Other pesticide constituents, including 4,4-DDE and 4,4- DDT, were identified at concentrations below their respective RSLs and CHHSLs. Based on the results of the investigations, soil impacted with toxaphene at concentrations above the U.S. EPA RSLs and CHHSLs was present from ground surface to a maximum estimated depth of 1 foot below ground surface. The impacted soils were located generally throughout the property. The proposed property developer (City Ventures) plans to excavate and stockpile (on- site) the soil that contains toxaphene at levels higher than the established site cleanup level for this pesticide. All impacted soil removed by the excavation above the site cleanup level will be placed in on excavation created on-site and have a minimum of 7 feet of clean soil cover, or greater fill depths as directed by the site civil engineer to ovoid contact with utilities. This soil will be placed below the roadway and, if necessary, building footprints and front yards of the proposed residential units. Grading of the Site will involve heavy earth-moving equipment to excavate the impacted soil and deposit these soils within specifically placed excavations. Clean fill material will cover the impacted soil and will be compacted for the safe construction of structures. Exposure to toxaphene through inhalation, dermal contact, and ingestion of airborne dust particles could pose a public health concern. Additionally, noise and hazards associated with large moving equipment will also presented by earth grading operations. At the Site, however, precautions will be exercised in order to reduce the exposure concerns to a minimal level. County of San Diego, Department of Environmental Health PESTICIDE REMEDIAL ACTION WORKPLAN, Carlsbad, California Page 2 Based on the Site's location within a predominantly residential area, proper protocols will need to be in place during the remedial activities to reduce exposure to potential health hazards for the nearby residences and construction workers. Contaminant Characteristics Toxaphene was the only pesticide found at the Site at concentrations that exceed State and Federal screening levels. All other pesticides were found to be significantly below levels which ore thought to pose a human exposure concern. Therefore, this study will focus on the characteristics and occurrence of toxophene-contaminated soil. According to the US EPA, toxaphene is a mixture of 670 chemicals, is non-combustible, and has been detected in soil and food, particularly fish. Toxaphene will strongly sorb to soil particles and persist in the environment for many years without degradation. It is not very water soluble and, therefore, does not migrate in groundwater or represent a concern for groundwater contamination. Toxaphene generally does not diffuse in air unless it is in solution; therefore, if buried, contaminant vapor migration is not a concern. The Occupational Safety & Health Administration (OSHA) recommends a maximum average amount of air exposure of toxaphene to workers not exceed 0.5 milligrams per cubic meter of air (mg/m^) per 8-hour workday over a 40-hour work week. According to the US EPA, toxaphene is a probable human carcinogen and is classified as a carcinogen based on animal studies. Exposure to toxaphene has been shown to affect a variety of organs including the liver, kidneys, spleen, the central nen/ous system, and immune system. Chronic inhalation in humans has been reported to cause reversible respiratory toxicity. The US EPA restricted use of toxaphene in 1982 and it is currently in use for limited purposes including emergency treatment of crops, for banana and pineapple crops, and for treatment of some conditions in cattle. According to the US EPA, the main effects of short-term exposure to high concentrations to toxaphene include central nervous system stimulation, with the most severe symptom being seizures. Animal studies hove shown effects on the liver, kidneys, spleen, central nervous system and immune system following oral exposure. It may result in reproductive effects. Methods of Exposure The primary source of contamination was the legal application of agricultural pesticides to crops at the Site. The secondor/ source of contamination is the soil grains that the pesticides have bound to. The primor/ mode of transportation is wind and earth-moving operations during proposed grading. Additionally, a less likely mode of transportation is bioaccumulation of pesticides in plant material such as edible fruit and vegetables. County of San Diego, Department of Environmental Healtli PESTICIDE REMEDIAL ACTION WORKPLAN, Carlsbad, California Page 3 The direct exposure to toxaphene-impacted soil through ingestion, inhalation, and dermal contact is the main human health concern. Activities that involve the handling of impacted soil, such as gardening and home improvements that involve excavation work, may result in exposure. Bioaccumulation results in the uptake of chemical pesticides into edible fruits and vegetables. Fruits and vegetables grown in toxophene-treoted soil may have resulted in the appearance of toxaphene in some food sources such as fish. The burial of the impacted soil to a depth of 7 feet below ground surface, or to fill depths as directed by the site civil engineer to ovoid contact with utilities - placed beneath soil with pesticide contents that is either at "non-defect" levels or below the site cleanup levels - would eliminate the risk of plant uptake of toxaphene. Inhalation of airborne dust is another route for exposure to toxaphene. Due to the chemical characteristics of toxaphene, vapor intrusion, leaching, and groundwater impacts ore not concerns. The application of water during soil movement activities and the performance of dust monitoring will be performed to minimize any exposure from this pathway. Monitorinq To dote, Stantec is unaware of any monitoring devices that detect toxaphene concentrations in real time. Although air samples can be collected via the glass fiber filter method, the samples would need to be analyzed at on off-site fixed laborator/ and, therefore, would be of little to no use in the field for real time monitoring. Therefore, Stantec recommends deploying dust monitors to verify the dust being transported off of the property does not contain pesticides at levels of concern. Additionally, a handheld dust monitor will be used to monitor the perimeter for dust periodically throughout the day. Visual dust monitoring will occur throughout the grading process. If dust is generated, immediate water suppression will occur to control its movement. If wind speeds exceed 13 miles per hour the grading process will be suspended until the wind speed decreases to the required speed. Engineering Controls The following engineering controls will be utilized in order to reduce the risk of human exposure to toxophene-contaminated soil during remedial activities: Dust During movement of impacted soil, efforts will be made to reduce the generation of and distribution of dust. Prior to movement of soil the surface will be watered to ensure moisture penetrates into the soil to be excavated. During movement of soil, large amounts of water will be used to reduce dust generation at the Site. If the wind sustained speed exceeds 13 miles per hour for over 30 minutes, grading County of San Diego, Department of Environmentai Health PESTICIDE REMEDIAL ACTION WORKPLAN, Corlsbad, California Page 4 activities will cease until the wind speed subsides to levels below 13 miles per hour. Wind speed will be recorded as well as direction during the course of the working hours. The impacted soil removed from the excavations will be stockpiled onsite in designated areas. All impacted soil will be covered when aboveground by plastic sheeting at the end of the working day to reduce the potential for dust migration from the Site. Large amounts of water will be used at all times during soil movement to reduce and control dust. In addition, perimeter dust monitoring will be conducted in accordance with the approved procedures specified in section in the document covering dust monitoring. Site Security The Site will be fenced and gated, limiting access to only those authorized to be on-site. Noise Equipment operation times will be dictated by the City of Corlsbod Zoning Ordinances. The Site is surrounding by residential neighborhoods. It is anticipated that noise may be on issue which will require some level of cooperation between the developer and the surrounding neighborhoods. Open Excavations Given the size of the potential excavations, the excavations will need to remain open overnight. As a result, illegal entr/ to the Site is a concern after hours. Ever/ effort will be mode to backfill excavations of the end of each workday but, for those that remain open, proper fencing and flagging of the excavation will occur. In addition, proper slopes will be maintained as well as one open end for ease of entry and exit from the excavations. Soil Management To ensure that impacted soil is not carried off-site, all vehicles and equipment should be inspected prior to exiting the Site. If significant amounts of soil ore trapped within the tires or under-corrioge of vehicles, the soil should be removed prior to the vehicle exiting the Site. During and of the end of each day, any soil deposited on Oak Avenue or Valley Street outside the exit of the Site should be swept up and returned to the Site for proper management. Best Management Practices If site development is required during rainy periods, core should be token to minimize the negative effects. Stantec recommends that no work be conducted County of San Diego, Department of Environmental Health PESTICIDE REMEDIAL ACTION WORKPLAN, Corlsbod, California Page 5 when the potential for roin is significant. Educated judgment should be used to determine the significance of the potential rainfall event and how it might affect the remedial grading activities. If a significant rainfall event is anticipated or occurs during construction operations, necessar/ measures must be token to minimize erosion of stockpiles and limit soil erosion from off-site migration. A Storm Water Pollution Prevention Plan (SWPPP) has been prepared and a copy of the map included in the RAP. Site Safety Officer The designated project superintendent chosen by City Ventures will serve as the Site Safety Officer. Stantec will assist the Site Safety Officer in areas where they ore unfamiliar with site safety. The job of the Site Safety Officer will be to monitor dust control and ensure that the Site is only accessed by authorized personnel. In the event of an emergency, the Site Safety Officer will hove the authority to shut down site activities and the knowledge to notify the appropriate emergency responders. Emergency PIgnning Toxaphene is non-flammable and does not represent a fire or explosion concern. In the event of on emergency where site activities ore halted, necessary measures must be token to ensure that contaminated soil does not leave the Site. All stockpiles must be covered with plastic sheeting and trenches must be fenced and protected from entr/ by unauthorized people and animals. In the event of an emergency, the Site Safety Officer must notify the following agencies or individuals: City of Carlsbad Fire Department: 911 or 760-931-2141 City of Corlsbod Emergency Operations: 760-931-2137 San Diego Department of Environmental Health: Carol Fenner-858-505-6896 Public Notification Prior to the implementation of the proposed work, public notices will be mailed or hand- delivered to neighboring residences contiguous to the subject property. The notices will identify the proposed work, days and hours of operation, and on estimated schedule of the project. Details will include: Site Safety Officer's and Stontec's contact information, identification of potential concerns including dust and noise; a brief description of planned activities, and the Proposition 65 Warning of the potential exposure to chemicals known or suspected by the State of California to cause cancer. Notices will also be placed on the fence surrounding the Site's perimeter immediately prior to start of construction activities. Stantec will prepare o public notification letter for distribution to the neighbors using the example provided in the most recent Son Diego County Department of Environmental Health Site Assessment and Mitigation Manual. County of San Diego, Department of Environmental Health PESTICIDE REMEDIAL ACTION WORKPLAN, Corlsbad, California Page 6 Traffic Control Plan The Site is located within o residential area of Carisbod. The main roadways to access the Site (Oak Avenue and Valley Street) consist of undivided two-lane paved roads with parking allowed on the shoulder. Additionally, there ore no sidewalks along either street. If necessar/, trucks importing clean soil will hove to travel approximately 0.5 mile on these residential roads to access the Site. Trucks and oil other vehicles should be aware of the following precautions: • The maximum speed limit on residential roads is 25 miles per hour (mph). Large trucks should limit their speed to 15 mph to account for their longer stopping distance; • Cars parked on the shoulder could limit the width of the roadway. Trucks should use caution when passing parked cars and should yield to on-coming traffic; • Due to the lock of sidewalks, residents may be walking or children may be playing in the street. Drivers of trucks and other vehicles must be alert at all times. The Site is located at on intersection. This may create a hazard as large trucks slowly exit the Site onto either Oak Avenue or Valley Street. Traffic Warning Devices should be in place to alert drivers that large trucks may be merging onto either roadway. In addition, a flogger may be used to alert on-coming traffic that a large truck is merging onto either roadway. APPENDIX B SITE SPECIFIC HEALTH AND SAFETY PLAH stantec Site-Specific Health and Safety Plan Soil Excavation Proposed Residential Property SWC Oak Avenue and Valley Street Carlsbad, California Prepared for: City Ventures 1900 Quail Street Newport Beacti, California 92660 Submitted by: Stantec Consulting Corporation 25864-F Business Center Drive Redlands, California 92374 June 29, 2012 Purpose and Approval Our work can be hazardous, and it is imperative that we never forget that! It is the purpose of this Health and Safety Plan (HASP) to proactively aid Stantec employees in: • Identifying and understanding the risks/hazards they are likely to encounter at the site. • Mitigating those risks/hazards. Stantec's policy is to complete our work on this site without any type of incident (injury, illness, impact to the environment, impact to property and equipment). In order to achieve this goal, the project team will work together to perform an effective hazard assessment. The team will then establish appropriate precautions and communicate these daily among project staff. Staff will be responsible for communicating changing field conditions to the project management so these conditions and appropriate precautions may be re-evaluated as needed. Staff will implement STOP WORK AUTHORITY at any time they believe that conditions may be inherently unsafe or might cause damage to property or harm to the environment. Staff may refuse to participate in work they believe will be unsafe. If such conditions exist, staff will communicate immediately with the Project Manager to resolve the situation. We expect all subcontractors and project personnel to share this goal.

The field staff may also call the Project Manager, Kyle Emerson, 909-255-8220. Site-Specific Health and Safety Plan for Soil Excavation 12 Proposed Residenlial Property, Carisbad CA stantec 3.0 Site Background and Chemical Hazards stantec connpleted a Phase I ESA for the subject property and issued a report of findings on January 27, 2012. Stantec determined that the Site was historically used for agricultural purposes. Due to the potential for pesticide and arsenic based herbicides in soil at or exceeding human health risk or hazardous waste levels, Stantec concluded that the historical agricultural use of the Site represented a recognized environmental condition (REC) to the Site. Stantec recommended performing a Phase II ESA to evaluate the concentrations of organochlorine pesticides and arsenic in soils on the property. Stantec completed a Phase II ESA on the subject property on March 30, 2012. That Phase II ESA was designed to evaluate whether residual pesticides were present at concentrations that would affect the residential development of the Site. The Phase II ESA identified the presence of the organochlorine pesticide toxaphene, in shallow soil at concentrations above current California Human Health Screening Level (CHHSL) for residential use. The lateral and vertical limits of the toxaphene in soil were not defined by the completed assessment. Stantec recommended that further assessment be completed to more accurately assess the lateral and vertical limits of this organochlorine pesticide. The results ofthe Phase II investigation are summarized below. Stantec conducted the recommended additional Phase II ESA at the Site on May 14 and 15, 2012. The additional Phase 11 ESA consisted of a total of sixteen (16) hand auger borings located across the Site in order to further delineate the pesticide-impacted soil identified by the previous Phase II ESA. Pesticides The soil sample analytical results for pesticides are presented in Table 1. Chemical analysis of all analyzed shallow soil samples reported the presence of organochlorine pesticides, with the exception of location HA-17. The detected organochlorine pesticides included 4,4'-DDE, 4,4'- DDT, and toxaphene. Toxaphene was the only organochlorine pesticide detected above the federal Regional Screening Level (RSL) of 0.44 mg/kg, and the California Human Health Screening Level (CHHSL) of 0.46 mg/kg for residential uses for this compound. The peak concentration of toxaphene was 2.1 mg/kg located in HA-10 at the 0.5 to 1 foot below ground surface ("bgs") interval. Toxaphene was only detected above the RSL and CHHSL in the samples collected from 0.5 to 1.0 feet bgs. Samples collected from 2.5 to 3.0 feet bgs detected no toxaphene or any other organochlorine pesticides above their RSL or CHHSL. The highest concentrations of 4,4'-DDE and 4,4-DDT were 0.24 mg/kg and 0.16 mg/kg, respectively. Both were detected in sample location HA-9 at the 0.5 to 1 foot bgs interval. The detected concentrations of 4,4'-DDT and 4,4'-DDE are well below their respective RSLs of 1.7 mg/kg and CHHSLs of 1.6 mg/kg for both 4,4'-DDE and 4,4'-DDT, and the California hazardous Site-Specific Health and Safety Plan for Soil Excavation 13 Proposed Residential Property, Carisbad CA stantec waste disposal level for 4,4'-DDE and 4,4'-DDT of 1.0 mg/kg. Toxaphene was the only pesticide detected above regulatory thresholds. Stantec estimates that an area containing the elevated toxaphene concentrations is approximately 107,000 square feet in size. The data collected suggests an assumed average depth of 1.5 feet bgs where toxaphene may be present above the CHHSL. Based on the above aerial distribution and an assumed 1.5 foot depth, the assumed volume of impacted soil is estimated to be approximately 6,000 cubic yards. Based on the elevated concentrations of toxaphene, the County of San Diego Department of Environmental Health ("CSDDEH") will likely require management of the material prior to approving Site development. The two best options for managing the material, based on ability to obtain approval and based on cost, are (1) on-site burial and (2) off-site disposal. The City of Carlsbad has agreed to abide by CSDDEH directives in regard to the potential remedial options. Based on the volume of impacted soil at the Site, on-site burial is the more cost effective remedial option. Stantec proposes that during the Site grading the soil impacted with toxaphene above the site cleanup levels (U.S. EPA RSLs and CHHSLs) will be excavated and stockpiled on-site. The depth of excavation will be dictated by the previous site assessment data. The stockpiled soil will then be used in the remedial backfill. Due to space limitations on the property, the pesticide-impacted soil will be removed in sections as required by the Site grading contractor. Stantec proposes to provide observations of the toxaphene-impacted soil removals. Representative soil samples will be collected from the base of the excavation to verify that toxaphene has been removed to the Site cleanup levels. Historical soil samples results will be used to guide the excavation depths in advance of verification sampling. Once the remedial objectives have been achieved no further remedial excavation will occur in those areas. Collected soil samples will be tested in a State of California certified laboratory. All samples will be analyzed for organochloride pesticides by EPA test method 8081. These results will be used to establish both remedial excavation depths and areas where re-use or cap soil exists. Once the impacted soil has been removed and stockpiled, the remedial excavation will be expanded for placement. The depth of these excavations will be determined based on the volume of soil to be placed. The impacted soil will then be placed within the base of the excavation which will be located primarily beneath the roadway below utility depth, and in the event that a larger excavation is needed, also below building foot prints and front yards. The impacted soil will be covered with no less than 5 feet of soil containing concentrations of toxaphene below the Site cleanup levels. Impacted soil will not be buried beneath backyards in case of future swimming pool construction. Site-Specific Health and Safety Plan for Soil Excavation 14 Proposed Residential Property, Carisbad CA stantec Conclusion Based on the presence of toxaphene above the current residential cleanup levels, Stantec anticipates that remedial action will be necessary at the Site. The current accepted remedial approach recommended for this property includes excavation of pesticide impacted soil above site cleanup levels, with on-site burial - covered with a clean cap of soil. The burial option for addressing the toxaphene-containing soil would include a deed restriction and notice. This option would be more cost-feasible in light of the large volume of soil on this Site, however. Further, this option has been approved for use recently in this area of CSDDEH's jurisdiction. Development of a remedial action plan (RAP), and community notice, will be required in order to obtain approval from the CSDDEH to implement the recommended approach for managing the toxaphene-impacted soil. Stantec recommends preparation of that document, with the community notice, in accordance with the relevant CSDDEH procedures.

During work hours None, with dust control Significant dust production The Level for Respirator Use is the concentration at which a respirator will be put on; it does not require the job to stop. The respirator is a tool to be used while determining why the exposure has reached that concentration. Take action to reduce the concentration using engineering controls such as water mist, spray foam, plastic cover, etc. The Level for Work Stoppage is the concentration at which work on the job will stop. Determine why exposures have reached that concentration and how they can be reduced. Site evacuation is not necessary at this level. Implement engineering controls to reduce the concentration, and then resume work. Photoionization detectors (PIDs) are used for general hydrocarbon monitoring; an example would be benzene, toluene, ethylbenzene, and xylene, common on gasoline station sites. The PID typically uses either a 10.6 eV lamp (responds to pentane and higher hydrocarbons), or 11.7 eV lamp (responds to ethane [weakly], propane and higher hydrocarbons) to ionize and detect the gas. The PID will measure hydrocarbons that are ionized, and therefore is a screening device, not a chemical-specific measurement instrument. The Levels for Work Stoppage are based on measurements taken using PIDs calibrated with isobutylene; PIDs calibrated with gases other than isobutylene may have a different response factor. Action levels can be modified with particular knowledge of contaminants and site conditions. In the following cases, contact Daniel Spencer for guidance on the air monitoring requirements. o When calibrating with a calibration gas other than isobutylene. o When requesting to modify the values above. o On sites impacted with chemicals other than petroleum products.

Earthquakes can last just a few seconds or as long as several minutes. Safety precautions include (as amended from http://safety.lovetoknow.com/Earthquake_Safety_Precautions): • Before an earthquake: o Store heavy items or glassware on low shelves so they do not become dangerous projectiles. Secure large equipment with straps, bolts, or other stabilizing methods, o Know the emergency meeting location at the site. • During an earthquake: o Immediately seek a safe location such as in a doon/vay, beneath a table or desk, or along an interior wall away from windows or hazardous objects, o Cover the bask of your head and your eyes to minimize injury from flying debris o Do not take elevators during an earthquake. o if outdoors, stay in open areas away from buildings, power lines, trees, and other potential hazards. o If driving, stop quickly but safely and stay in the vehicle. Do not stop near power lines, bridges, overpasses, or other potentially dangerous locations, o Stay calm and brace yourself to keep you balance. Sit if possible. • After an earthquake: o Be prepared for aftershocks, which may be stronger than the initial jolt, o Administer First Aid and summon emergency assistance if necessary, o Wear PPE (boots, gloves) to avoid getting cut by broken glass, o Turn off gas, electricity, and water if damage is suspected or if advised to do so by authorities. o Be cautious opening cabinets, cupboards, and closets in case items are poised to fall, o Keep phone lines clear for emergency use. o Be patient: it may take hours or days to restore all services depending on the severity of the quake. Site-Specific Health and Safety Plan for Soil Excavation Proposed Residential Property, Carisbad CA 20 stantec 5.3 BIOLOGICAL HAZARDS Biological hazards may include, but are not limited to, bees/wasps, spiders, snakes, stray dogs, and poisonous/allergenic plants. The most likely biological hazards at the site are bees/wasps, and these may be encountered during a number of tasks including: opening well vault covers; opening core or sample boxes; working in tall grass, weeds, or brush; cleaning or moving materials; performing site assessment, etc. To mitigate hazards associated with bees/wasps: Avoid known locations of bees/wasps. Keep your eyes and ears open for swarms. Look for insects flying in and out of openings such as a crack in the wall, an open pipe end, or a well vault lid. Be cautious of tall grass as some bees build their hives at ground level. Be cautious of pointed structures, especially in barns, storage sheds, and outbuildings as bees often build hives in those structures. Avoid wearing citrus or floral aftershaves or perfumes as bees/wasps may be attracted to these odors. Wear light colored clothing as insects are generally attracted to dark colors. Fill in cracks or crevices and close open ends of pipes when bees/wasps are not around. Leave the area as quickly as possibly if a nest has been disturbed. Do not retrieve nearby belongings. Do not stand still. Do not try to fight them. If stung by a bee or wasp, wash the area with soap and water, and use Benadryl from the First Aid kit. If you have been stung over 15 times or are having symptoms other than pain and swelling, seek emergency medical assistance immediately. Staff that is allergic will carry an EpiPen® as prescribed by a doctor.

If appropriate, Stantec will include drug and alcohol testing, consistent with Stantec's Policies and Procedures, as well as the client's contractual requirements for testing. Exclusion Zone and Decontamination No eating, drinking, or smoking within the exclusion zone. These activities will be conducted only in designated areas of the site. Use of PDAs, cell phones, pagers, or other electrical devices (with the exception of intrinsically safe devices) are prohibited in the exclusion zone. Personnel will properly decontaminate after leaving an exclusion zone. Decontamination procedures may involve disposing of Tyveks, latex gloves, etc. in a decontamination zone located immediately outside of the exclusion zone. At a minimum, personnel will wash any exposed skin before leaving a site using soap and water or pre- moistened cleansing towels. Stantec will evaluate the hazards and develop site-specific decontamination procedures to address the chemical hazards at each site. These procedures can be found in the job safety analyses. HASP Inspections The site-specific HASP should be inspected in the field by the SHSO or other Stantec personnel to determine the effectiveness of the plan. Any deficiencies should be corrected and changes will be recorded on the HASP Modification Log. Site-Specific Health and Safety Plan for Soil Excavation Proposed Residential Property, Carisbad CA 22 stantec Jewelry Safetv Jewelry can be dangerous and shall not be worn during field activities. Large earrings, long necklaces, loose-fitting bracelets, rings, watches, etc. can become entangled in machinery and cause removal of limbs, as well as be conductive of electricity. Job Safetv Analvsis Job Safety Analyses (JSAs) will be prepared or revised prior to mobilizing to the field. Applicable JSAs will be reviewed in detail on a daily basis by all affected on-site workers and/or visitors. Any revisions to the JSAs will be hand written into the JSAs, forwarded to the project manager, and communicated to during Daily Production Health and Safety Briefings. JSAs are located in Attachment 2. Material Safetv Data Sheets Material Safety Data Sheets (MSDSs) will be available in the 7-Eleven Team Field Binder for all chemicals that may be found on site (including chemicals that will be brought on site by on-site personnel and/or visitors). Permits This HASP will serve as the general permit to work for this site. Client specific work permits will be available in the 7-Eleven Team Field Binder. Personal Protective Eguipment PPE is identified in JSAs. PPE listed in each JSA is specific to the task outlined in the JSA and is consistent with Appendix B of 29 CFR 1910.120. PPE is to be used in accordance with manufacturers' recommendations. Minimum PPE at the site includes steel toe/steel shank boots, High visibility work gloves, hi-viz safety vest, long sleeve shirt, pants, safety glasses with side shields, and a hard hat. Pre-entry Briefing All on-site workers and visitors will receive a pre-entry briefing prior to accessing work areas of the site. The briefing will include reviewing contents of the HASP, signing the Acknowledgement and Agreement Form, and completing the Site Health and Safety Quiz (Attachment 4). Completed quizzes will be kept with the project files. The briefing for visitors may be abbreviated to be fit-for-purpose based on the intent of the visit. Public Questions and Press Questions about the site posed by neighbors, the press, or other interested parties will be directed to the Stantec Project Manager Shutoff Valves/Switches The SHSO will identify the iocation of shutoff valves and switches for utilities and products on the Site Plan and disseminate this information to all site personnel and visitors as appropriate. Site Access and Layout Before mobilizing to the site for an event, the property owner(s) will be notified. The property is currently occupied by a vacant commercial building. The exclusion zone(s) will be set around individual work locations using barricades and other delineators. Site Securitv Security of our staff, subcontractors, equipment, and the public is of paramount importance to Stantec. Employees are trained in hazard recognition and will follow standard policies and procedures to report and mitigate site security issues/hazards if identified. Note that security consideration is different than traffic guidance and control, which also impacts security to some extent. Security refers to personal safety and freedom from theft or violence. The following items will be evaluated when considering security measures at the site: • Daytime activities at the site (e.g., gas station only, gas station with convenience store, etc.); • Recent criminal activity at the site and nearby areas (ask site owner/operator and the police); Site-Specific Health and Safety Plan for Soil Excavation Proposed Residential Property, Carlsbad CA 23 stantec • Work hours (security concerns may be different depending on the time of day); and • Lighting at the site (thieves are generally dissuaded from stealing on well lit sites). Standard security measures will be implemented on site to minimize the potential for loss at the site. Standard security measures include properly maintained lighting, functioning locks for windows/doors/equipment storage areas, and maintaining control of tools and equipment when not in use. Security may be implemented in a variety of ways: Orange construction fence (minimal security); Chain link fencing; Extra lighting; Specialized locks; and/or Contract security. Traffic Guidance and Control Incidents on sites have shown the need for a site-specific Traffic Guidance and Control Plan. The SHSO and project staff will develop a Traffic Guidance and Control Plan and disseminate this information to all site personnel. This plan will consider the amount of traffic at a site and provide for the safety of all workers. Equipment and resources to be considered as part of traffic guidance and control include: Vehicle hazard lights (tail and headlights) Delineators and orange construction fencing Placement of vehicles as barriers between workers and traffic Rotating amber hazard lights that can be placed on top of vehicles Professionally trained flaggers Other considerations for the Traffic Guidance and Control Plan include: • Requiring personal vehicles (that aren't being used as barriers) to park as far away from potential traffic as possible. • Cordoning off as much space as is necessary to ensure our safety. This will be discussed with property owners and tenants, as it may mean closing down additional gasoline pumps, etc. • Identifying traffic flow routes and parking areas for heavy equipment (e.g., vacuum trucks, drill rigs, etc.) and establishing site speed limits. • Reviewing local regulations for: formally developed traffic guidance and control plans signed by licensed individuals, police details, flagmen, hours of activity, closure of streets, etc. Work Hours Work on this project will be conducted during the hours of 6:00 AM to 6:00 PM, Monday through Friday.

The Revised RAP was prepared by Stantec and uploaded to GeoTracker on November 26, 2013. The revised RAP was submitted on behalf of a developer (City Ventures) that intends to construct a 16-lot residential subdivision on former agricultural land at the southwest corner of Valley Street and Oak Avenue in Carlsbad, California. The Revised RAP and appended Community Health and Safety are not approved. Soil sample analytical data for the site supports Stantec's conclusion that toxaphene impacts in excess of Its California Human Health Screening Levels (CHHSL) are limited to a depth of one foot below ground surface. However, further review of the data raises a question regarding the representativeness of the 24 sampling locations. Although it appears that samples were collected more or less on an irregular grid pattern, the pattern was not followed in the northwest and southeast portions of the site. No explanation is provided in the text for the deviation from the quasi-grid pattern in these areas. DEH suggests that one of two approaches be considered to address these data gaps, which have a significant bearing on the volume of toxaphene-impacted soil to be excavated and buried onsite. 1. Collect additional samples in the northwest and southwest areas of the site indicated on Figure 2 of the Revised RAP. DEH estimates that 8 to 10 additional sample locations are needed to provide coverage comparable to that for the remainder of the site. 2. Revise the proposed soil removal areas shown on Figure 3 of the Revised RAP to excavate the entire site to a depth of one foot. "Environmental and public health through leadership, partnership and science" Mr. Joe Oflelie December 23, 2013 The "Proposed On-Site Pesticide Management" section requires revision. DEH suggests renaming this section "Proposed On-Site Impacted Soil Management" for clarification purposes. The main concern with respect to this section concerns dust monitoring and sampling procedures to be employed during proposed soil excavation, stockpiling, reburial, and fill placement activities. In its review letter of August 23,2013, DEH explicitly stated that these procedures be in accordance with those approved by DEH for the City Ventures property at 1264 Lake Drive in Encinitas. The Revised RAP and appended Community Health and Safety Plan submitted by Stantec do not adhere to this requirement. Please submit a second revised RAP and Community Health and Safety Pian that incorporates the air monitoring and sampling protocols in the following report, which was prepared for the City Ventures property at 1264 Lake Drive, Encinitias (DEH Case #39744-001): • "Soil Reuse Plan (Revision 3)," which was uploaded to GeoTracker on July 17,2012 DEH's Comment #3 in its review letter of July 24, 2012 shall also be incorporated into the Revised RAP and Community Health and Safety Plan for the Valley and Oak site. Minor edits to the texts ofthe Revised RAP and Community Health and Safety Plan will be emailed to Stantec. A revised RAP shall be submitted by January 10, 2013. Please call me at (858) 505-6896 if you have any questions concerning this review. Sincerely, CAROL A.

The RAP was prepared by Stantec and uploaded to GeoTracker on June 16, 2013. The RAP was submitted on behalf of a developer (City Ventures) that intends to construct a 16-lot residential subdivision on former agricultural land at the southwest corner of Valley Street and Oak Avenue in Carlsbad, California, Based on the findings of a Phase I environmental site assessment (ESA) and of a Phase II Investigation, Stantec recommended additional testing of soil underlying the 3.89-acre property for organochlorine pesticides (OCPs). A second Phase II investigation was performed in May 2012. According to the RAP, Stantec collected soil samples at 16 locations on the property during the second Phase II investigation and tested them for OCPs. The pesticides 4,4'-DDE, 4,4'-DDT, and toxaphene were detected in the soil samples, which were collected at depths of 0.5 to 1.0 foot and 2.5 to 3.0 feet using hand-auger techniques. Toxaphene was detected in 12 ofthe 16 soil samples collected from 0.5 to 1.0 foot. The maximum detected concentration of toxaphene was 2.1 mg/kg. The analytical results for nine of these samples exceeded the residential Califomia Human Health Screening Level (CHHSL) for toxaphene of 0.460 milligrams per kilogram (mg/kg). Analytical results for 4,4'-DDE and 4,4'-DDT were not provided in the RAP, but were reportedly below their respective CHHSLs. In the RAP, Stantec proposes excavation of toxaphene-impacted soil and re-burial on the property, primarily beneath a planned road ("James Drive"), as well as beneath residential building foundations and front yards, as needed. Based on an estimated impacted area of 107,000 square feet and an average estimated excavation depth of 1.5 feet, Stantec estimates that approximately 6,000 cubic yards of toxaphene-impacted soii would require re-burial on the property. "Environmental and public health through leadership, partnership and science" Mr. Joe Oflelie August 23, 2013 In order to properly evaluate the RAP, DEH requires that the following items be addressed: 1. Submit copies of the reports for both Phase 11 soil investigations to GeoTracker and provide paper copies to DEH. 2. DEH recommends performing additional soil sampling and OCR testing at the property for the depth interval between 1.0 and 2.5 feet. Having toxaphene concentration data from this interval upfront would be more cost-effective than iterative excavation based on confirmation sample results (i.e., no delay in operations while awaiting laboratory reports). The data and would also allow more accurate estimation of the volume of impacted material subject to reburial. DEH suggests collecting the additional samples at the locations where toxaphene concentrations exceed its CHHSL. 3. DEH requires a minimum 7-foot cap between the toxaphene-impacted material and final grade. Please revise the RAP to address this requirement. 4. Dust monitoring and sampling procedures to be employed at the property during soil excavation, stockpiling, reburial, and fill placement activrties shall be in accordance with the procedures approved for the City Ventures property at 1264 Lake Drive in Encinitas (DEH, July 24, 2013). 5. Provide a brief description of stomn water best management practices (BMPs) for the remedial activities. The description shall be accompanied by a map that uses symbols for specific BMPs (e.g., straw rolls, heavy equipment decontamination, detention basins) and shows where they would be implemented on the property. A revised RAP shall be submitted by September 30, 2013. Please call me at (858) 505-6896 ifyou have any questions conceming this review. Sincerely, CAROL A.
