CITY OF SAN LUIS OBISPO A Municipal Corporation __________________________________ Derek Johnson, City Manager APPROVED AS TO FORM CONTRACTOR: Name of Company ________________________________ By:________________________________ J. Christine Dietrick City Attorney Name of CAO/President Its: CAO/PRESIDENT Rev. 12-28-09 Rev. 2 5/12/16 DMA Page 1 of 9 Date: 2/7/2017 Prepared by: Dave Kremer, P.G. – HDR Reviewed by: Holly Kennedy Project: San Luis Obispo Indoor Gun Range SUBJECT: Gun Range Site Characterization INTRODUCTION This Site Characterization was prepared to document the methods and results from the assessment of the indoor small arms range (Range) located at 43 Prado Road in San Luis Obispo, California (Site) and depicted on Figure 1. PROJECT UNDERSTANDING The City of San Luis Obispo (City) intends to raze the Range and adjacent Prado Day Center to allow for the expansion of the San Luis Obispo Water Resource Recovery Facility (WRRF). Since the Site was formerly used as a small arms range it is possible that lead may be present onsite and on building surfaces that may present potential construction work health risk and limitations on the disposal of any disturbed soil. Prior to construction of the WRRF Upgrade project, the City desires to determine whether lead is present in the soil and building surfaces and understand the scope and potential costs associated with the decommission and demolition of the small arms range and proper disposal of any contaminated materials. SCOPE OF WORK The following activities were performed to evaluate the Site and adjacent property: Prepared the October 2016 Work Plan which identified methods to characterize the Site and adjacent property; Advanced ten soil borings to 1.5 feet below ground surface (bgs); Collected two soil samples from each boring and submitted these samples to a California certified laboratory for lead analysis via EPA Method 6010B; Collected eight building surface wipe samples from exterior surfaces and two building surface interior wipe samples; Submitted the wipe samples to a California certified laboratory for lead via method 6010B. Page 2 of 9 SITE CHARACTERIZATION ACTIVITIES The following sections document the methods used to collect soil and wipe samples from the Site and adjacent properties. Soil Boring Construction On October 25, 2016 HDR was met by Jasmine Diaz with Water Systems Consulting, Inc. and granted access to the Site and interior of the small arms range. Surface soil samples were collected from ground surface to approximately 6-inches bgs at the locations depicted on Figure 2. The surface soil samples were collected by scraping the ground surface with a laboratory supplied glass jar or by hand covered in a new nitrile glove. The surface soil sample was contained in the laboratory supplied jar, labeled with the sample identification (i.e. SLOGR-001- 0-NS), sample date and time, and analysis required. The sample container was then placed into an individual zip top bag and stored in an ice chest cooled with ice. After collection of the surface soil samples, subsurface soil samples were collected by advancing a 4-inch diameter hand auger to 1-foot bgs at the locations depicted on Figure 2. After reaching 1-foot bgs the hand auger was removed and a decontaminated slide hammer fitted with a new 2-inch diameter by 6-inch long stainless steel tube was advanced from 1-foot bgs to 1.5-feet bgs. After reaching the desired depth the stainless steel tube was removed from the slide hammer, capped with Teflon sheets and plastic end caps. The sample tube was labeled with the sample identification (i.e. SLOGR-001-1-NS) sample date and time, and analysis required. The sample tube was then placed into an individual zip top bag and stored in an ice chest cooled with ice. After collection of the soil samples, the borings were backfilled with the excavated soil and compacted and the boring coordinates were collected with a hand held global position system (GPS) unit. Wipe Sample Collection On October 25, 2016, surface wipe samples were collected from exterior surfaces of the Prado Day Center and from the exterior and interior of the indoor small arms range to determine if lead is present (Figure 3). Wipe samples were collected over a 100 square centimeter (cm2) area with new cotton gauze pads moistened in deionized water. The gauze pad was rubbed over the entire 100 cm2 area to remove any lead residue from the building surfaces in accordance with the NIOSH method referenced in the Work Plan. After wiping the area, the wipe sample was placed into laboratory supplied 4oz glass containers, labeled with the sample identification (i.e. SLOGR-011-WS-NS), sample date and time, and analysis required. The container was placed in a zip top bag and stored in an ice chest cooled with ice. The laboratory presents the results in milligram (mg) which represent mg per 100 cm2. Page 3 of 9 Equipment Decontamination Non disposable equipment that came into contact with the samples was decontaminated between use to prevent cross contamination. Furthermore, care was taken when selecting sample locations, to work from areas suspected to contain lower lead concentrations to areas suspected to contain greater lead concentrations. Equipment decontamination was performed by spraying the used equipment with Alconox and distilled water. A dish brush was used in some cases to remove soil that was stuck to the sampler. After the washing the equipment with the Alconox solution, the tool was sprayed with distilled water to rinse and allowed to dry on a paper towel. Quality Control Samples Quality control (QC) samples were collected to evaluate laboratory precision, decontamination methods, and determine whether the deionized water, wipe sample containers, or new wipes contained lead. A matrix spike and matrix spike duplicate were prepared and analyzed by the laboratory to evaluate analytical precision. To determine whether laboratory containers, the wipes, or the deionized water used to moisten the wipes contain lead HDR collected blank sample SLOGR-Blank-NS. This blank was prepared by dipping a new wipe sample into the laboratory supplied container which contained deionized water to moisten the wipe. The wipe was squeezed to remove any excess water and placed into the laboratory supplied container and submitted for analysis. To evaluate equipment decontamination methods the core sampler cup was decontaminated, as was done between sample locations. Laboratory supplied deionized water was poured onto the core sampler cup and collected in laboratory supplied containers which contained nitric acid as a preservative. The rinse blank (SLOGR-RB1-NS) was submitted to the laboratory for analysis. RESULTS The laboratory analytical report is included in Appendix A. The soil sample and wipe sample results summarized on Table 1 and Table 2, respectively. The following sections document the analytical results from the soil and wipe sample analysis.

(Alpha) a California ELAP certified laboratory. The samples were analyzed via United States Environmental Protection Agency (U.S. EPA) Method 6010B within the U.S. EPA’s recommended holding time. The lead concentration ranged from 7 milligrams per kilogram (mg/kg) in the surface soil sample collected from boring SLOGR-004, located north of the Prado Day Center to 930 mg/kg collected from the ground surface from the unpaved area inside the Range. Subsurface samples collected from borings SLOGR-001 and SLOGR-003 were the only samples which did not yield lead greater than the 5.0 mg/kg laboratory reporting limit (Table 1). Detectable lead concentrations in subsurface soil samples ranged from 9.3 mg/kg, collected from boring SLOGR-008, to 75 mg/kg, collected from soil boring SLOGR-006. A subsurface soil sample could not be collected from boring SLOGR-004 as asphalt was encountered at approximately 8-inches bgs. Soil samples collected from boring SLOGR-006, outside of the suspected impact area of the Range, were intended to establish the naturally occurring lead concentrations in soil. The surface soil sample collected from boring SLOGR-006 yielded lead at 42 mg/kg and the subsurface soil sample yielded lead at 75 mg/kg. Due to elevated lead levels (greater than 50 mg/kg) present on site from SLOGR-009, SLOGR- 010, and SLOGR-021, Soluble Threshold Limit Concentration (STLC) analysis was performed via EPA Method 6000/7000. The results ranged from 0.72 mg/L in SLOGR-021 to 170 mg/L in SLOGR-010 (Table 1). Samples with STLC results greater than 5 mg/L were analyzed for Toxic Characterization Leaching Procedure (TCLP) via EPA Method 6000/7000. The results ranged from 33 mg/L in SLOGR-009 to 76 mg/L in SLOGR-010 (Table 1). Page 6 of 9 Wipe Sample Analytical Results Wipe samples were analyzed at Alpha via U.S. EPA Method 6010B in accordance with U.S. EPA sample holding times. Four of the ten wipe samples contained lead greater than the 0.002 mg laboratory reporting limit. Detectable lead concentrations ranged from 0.0054 mg/100 cm2 in the sample collected from the outside of the western wall of the Range to 12 mg/100 cm2 in the sample collected from the interior wall of the Range. While there is no cleanup standard for lead concentrations associated with wipe sample results for the demolition and disposal of the Range materials, these results are used by the lead remediation subcontractor to determine if a construction worker safety issue is present and to determine the appropriate level of treatment to mitigate the potential safety concerns. Quality Control Sample Results In order to evaluate field decontamination methods a rinse blank sample (SLOGR-RB1-NS) was collected and analyzed at Alpha. Lead was not detected in the rinse blank greater than the 0.050 milligrams per liter (mg/L) laboratory reporting limit. An unused wipe was moistened in the field and submitted to Alpha for analysis to determine whether the wipes or water used to moisten the wipes contained measureable lead. The blank wipe sample (SLOGR-BLANK-NS) did not contain lead greater than the 0.0020 mg laboratory reporting limit. In order to evaluate the precision of the laboratory testing methods, Alpha spiked soil with a known mass of lead referred to as a matrix spike. The spiked soil was analyzed by Alpha to determine if the recovered result was within the U.S. EPA’s accepted range (70% - 130%) for Method 6010B. The percent recovered was 265, which is outside the U.S. EPA’s accepted range. While the spike recovery was outside of QC acceptance limits for the matrix spike due to analyte concentration at 4 times greater the spike concentration. The QC batch was accepted by Alpha based on laboratory control spike and/or laboratory control spike duplicate recoveries within the acceptance limits. DISCUSSION The following sections discuss the results from the sampling and how the presence of lead may impact construction workers, future land use, and waste disposal. Soil Sample Results Laboratory analysis of soil samples yielded low concentrations of lead, generally consistent with background sample results collected from boring SLOGR-006. The lead concentrations reported in surface and subsurface samples, outside of the Range, demonstrate that use of the Range has not contaminated shallow soil with lead above concentrations consistent with background. Surface soil samples collected from boring SLOGR-009 and SLOGR-010, from the Range floor, yielded lead at 930 mg/kg and 900 mg/kg, respectively. Lead was detected in subsurface soil samples collected from borings SLOGR-009 and SLOGR-010 at 21 mg/kg and 16 mg/kg, respectively. These lead concentrations in the subsurface samples collected from the Range Page 7 of 9 floor are consistent with background and have effectively delineated the vertical extent of lead detected on the Range floor. Lead was detected in surface soil samples collected from the Range floor at concentrations greater than the 800 mg/kg U.S. EPA Regional Screening Level (RSL) for industrial land use (Table 1). RSLs are generic values calculated by the U.S. EPA using exposure values, toxicity assumptions, chemical and physical properties that can be used to quickly identify contaminants that may pose an unacceptable risk to human health. Where contaminant concentrations are reported less than the RSL it can be safely assumed that the chemical does not present a risk to human health. When contaminants are detected greater than their applicable screening level, further action is typically warranted. Further action may include completion of a site specific human health risk assessment, land use covenant, or remediation. Waste Profiling and Disposal In the event that the soil may be transported off-site for disposal, samples SLOGR-009-0-NS, SLOGR-010-0-NS, and SLOGR-21-0-NS were analyzed for STLC (22 CCR § 66261.24) because they contained total lead concentrations greater than 10 times the STLC concentration classified as a California hazardous waste (5 mg/L). The results of the STLC analysis indicate that the surface soil from borings SLOGR-009 and SLOGR-010 is characterized as a California hazardous waste. Because samples SLOGR-009-0-NS and SLOGR-010-0-NS had STLC results greater than 5 mg/L and the total lead concentration is greater than 20 times the TCLP concentration classified as a Resource Conservation and Recovery Act (RCRA) waste, these samples were analyzed for TCLP. The results of the TCLP analysis indicate that the surface soil from borings SLOGR-009 and SLOGR-010 is characterized as a RCRA waste. Wipe Sample Results Wipe samples were collected to determine whether surfaces of the Range and adjacent Prado Day Center contained detectable lead concentrations. The greatest lead concentration was reported in the sample collected from the inside of the Range near the bullet traps. The wipe samples indicate that there is a clear presence of lead on the walls from an air borne source (muzzle blast) and that lead would become air borne during demolition activities. Per Cal/OSHA CCR Section 1532.1, the presence of lead concentrations within the Range indicates that the potential airborne lead exposure to construction workers would, if left unabated, require the contractor’s staff to be properly trained to work in a potentially hazardous environment, use of specific personal protective equipment, and potentially air and/or medical monitoring. Abatement would eliminate that potential exposure and reduce or eliminate the need for monitoring. CONCLUSIONS Lead detected in surface and subsurface soil samples collected outside of the Range is consistent with background and is likely naturally occurring. The surface soil samples collected from the Range floor yielded total lead concentrations greater than the industrial RSL, as well as Page 8 of 9 STLC concentration greater than 5 mg/L (California hazardous waste) and TCLP concentration greater than 5 mg/L (RCRA waste). Wipe samples collected from the exterior of the Range and the Prado Day Center indicate that there is no potential construction worker safety concerns associated with airborne lead. The wipe samples collected from the interior of the Range did contain elevated lead concentrations requiring abatement prior to demolition to mitigate potential construction worker safety concerns without the need for air monitoring and specially trained staff to work in a potentially hazardous environment. The technical approach for the lead abatement and demolition activities are presented in Appendix B. RECOMMENDATIONS In order to reduce handling, transportation, and disposal cost, it is recommended that the lead impacted soil in the interior of the Range be treated in-situ prior to demolition. Based on an approximate 2,025 square foot unpaved area of the Range floor and an eight inch assumed depth of lead impacted soil, it is estimated that approximately 60 cubic yards of lead impacted soil will need to be treated in-situ. Once the Range is demolished and removed, the soil will be excavated and disposed at a local landfill as non-hazardous waste. Due to the elevated lead concentrations detected in wipe samples collected from the interior of the Range, it is recommended that lead treatment on the interior surfaces of the Range be performed prior to demolition to mitigate potential construction worker safety concerns and ensure disposal of the waste as construction debris. The estimated costs to perform the lead abatement, demolition, and required reporting are summarized in Table 3. As shown, the estimated cost is approximately $220,000. Table 3.

Page 4 of 4 HDR | Indoor Gun Range Demolition - Technical Approach Indoor Gun Range Demolition - Technical Approach Date: Friday, February 03, 2017 Project: San Luis Obispo Indoor Gun Range To: From: Dave Kremer, P.G. – HDR Subject: Indoor gun range demolition – technical approach The purpose of this memo is to summarize the technical approach for the lead abatement and demolition of the San Luis Obispo indoor gun range. PROJECT OBJECTIVE The objective of the lead abatement is to provide various services to mitigate/reduce the heath risks to construction workers and costs associated with lead dust and fragments at the gun range. The objective of the demolition is to disconnect all utilities to the gun range and remove the structure down to bare earth. LEAD ABATEMENT APPROACH The lead abatement approach will include the following activities.  Lead Removal/Recycling – A contractor would perform lead removal from the bullet traps and range floor. This service should focus on economically recoverable lead within these areas. The lead would be stored in drums and transported to a local recycling facility.  Lead Cleaning/Mitigation – A contractor would perform a “bulk decontamination” of the building. The goal would be to HEPA vacuum visible, standing dust of accessible areas that may be considered lead-containing. In addition, limited wet-wiping of interior items (such as desks, chairs, cabinets, etc.) may also occur.  Guaranteed ECOBOND® Lead Stabilization – HDR’s estimate of probable construction cost included the use of a contractor that maintains a broad portfolio of patented and proprietary chemical metals stabilization processes that provide permanent stabilization of all heavy metals including lead. The resulting treated materials contain extremely stable metal compounds that virtually eliminate the leaching of metals to the environment. Application of a lead stabilization reagent, such as ECOBOND®, to firing range materials is a Best Management Practice (BMP) for range soils as identified in the US EPA Best Management Practices at Outdoor Shooting Ranges (USE EPA 2005). Confirmation samples would be collected to confirm that potential health risks to construction workers have been mitigated, that the structure materials and the contents within the structure can be disposed of as general construction debris, and the treated soil can be dispose of as non-hazardous.  Reporting – Finally a lead abatement technical memorandum should be prepared to summarize the onsite activities performed, the dates and timeframe in which the work was performed, confirmation sample results and laboratory data packages, documentation of the amount of lead recovered and recycled from the range, and the certificate of recycling. GUN RANGE DEMOLITION APPROACH Once the lead abatement activities are completed a local demolition company could be contracted to perform a standard building demolition. The general scope of work would include the following:  Utility disconnects to the structure,  Remove any contents from within the structure for disposal,  Demolition of the structure to bare earth,  Removal of all construction debris and transport to landfill for disposal and/or recycling, and  Removal and disposal of 60 cubic yards or 90 tons of soil. CLOSURE REPORTING Upon completion of the remediation, demolition, and disposal of wastes, a closure report should be prepared to document activities that were conducted. This closure report should include, but would not be limited to the following:  Site assessment findings, conclusions, and recommendations  Equipment and personnel utilized in the remediation and demolition activities  Volumes of wastes generated  Confirmation sample results  Site restoration  Photograph log of activities performed  Daily field logs and sample forms  Laboratory data packages  Signed landfill manifests  Deviations to the methods and/or procedures outlined in the work plan 1 May 10, 2017 Michael McGuire City of San Luis Obispo – Public Works 919 Palm Street San Luis Obispo, CA 93401 RE: Asbestos Building Inspection – 43 Prado Road, San Luis Obispo, California INTRODUCTION This report presents the findings of West Coast Safety Consultants inspection for asbestos containing building materials at the old gun range located at 43 Prado Road, San Luis Obispo, California on May 5, 2017.

Laboratory sample identification number c. Analytical technique d. Quality control procedures e. Type and percentage of asbestos in each material 4581 Wavertree Street $ San Luis Obispo, CA 93401 $ Phone (805) 748-8832 2 3. Analyzed the sample results and generated this report which includes: a. Definitions b. Executive Summary c. Findings d. Conclusions and Recommendations e. Sample Result Summary (Appendix A) f. Sample Location Diagram (Appendix B) g. Laboratory Report (Appendix C) h. Inspectors Credentials (Appendix D) DEFINITIONS Asbestos Types of asbestos include chrysotile, amosite, crocidolite, tremolite, anthophyllite, actinolite and any of these minerals that have been chemically treated and/or altered. Asbestos Containing Material (ACM) Means any material containing more than one percent asbestos. Category I Non-friable ACM Asbestos containing packings, gaskets, resilient floor coverings, and asphalt roofing products containing more than 1 percent asbestos as determined using the method specified in Appendix A, Subpart F, 40 CFR Part 763, Section 1, Polarized Light Microscopy (PLM). Category II Non-friable ACM Any non-friable material, excluding Category I Non-friable ACM, containing more than 1% asbestos as determined using PLM. Friable ACM Any material containing more than 1% asbestos as determined using PLM that when dry can be crumbled, pulverized, or reduced to powder by hand pressure. NESHAPS The National Emission Standards for Hazardous Air Pollutants (40 CFR Part 61). Regulated Asbestos Containing Material (RACM) Any material containing more than 1% asbestos which is: a. Friable or; b. Category I Non-friable ACM that has become friable or; c. Category I Non-friable ACM that will be or has been subjected to sanding, grinding, cutting, abrading or; d. Category II ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to a powder by the forces expected to act on the material in the course of demolition. WEST COAST SAFETY CONSULTANTS 3 EXECUTIVE SUMMARY MATERIALS WHICH CONTAIN ASBESTOS: Drywall/Joint Compound located on the interior walls contains a trace (<1%) chrysotile asbestos. SUSPECT MATERIALS WHICH NO ASBESTOS WAS DETECTED: Shingle and Felt Roofing Materials were sampled and no asbestos was detected in any of the samples. FINDINGS West Coast Safety Consultants collected samples of each suspect asbestos containing building material (ACBM) encountered at the specific site location. The Environmental Protection Agency (EPA) sampling protocol was utilized which requires multiple samples of suspect asbestos containing materials which are applied by spraying or troweling. A total of five (5) samples were submitted to Forensic Analytical Services, Inc., an EPA accredited laboratory for analytical testing. Laboratory results are found in appendix C of this report. The asbestos samples were analyzed for the presence of asbestos by Polarized Light Microscopy (PLM) with dispersion staining in accordance with the EPA Method 600/R-93-116, Visual Area Estimation. Of the five (5) samples that were analyzed for asbestos, three (3) were found to contain asbestos. The location of these samples, their description, and our recommended solution to mitigate any potential hazards emanating from contact with these materials is as follows: Sample Number: GR-01, GR-02, GR-03 Sample Description: Drywall/Joint Compound Location of Material: Interior Walls Quantity of Material: Approximately 500 Square Feet Type and % Asbestos: Trace (<1%) Chrysotile NESHAP Classification: Not regulated because the material contains less than 1% asbestos. Overall Condition: The material was generally intact and in good condition, however the bathroom was significantly damaged from water. Disturbance Potential: Slight because the asbestos is only located in the joint compound which is covered by layers of paint. Recommended Response: This material should be maintained in its current condition, and removed prior to demolition, renovation, or any other activity which would disturb the material by an asbestos abatement contractor that is licensed by the State of California. Do not sand, saw, or abrade the material. WEST COAST SAFETY CONSULTANTS 4 CONCLUSIONS AND RECOMMENDATIONS The asbestos containing materials identified in this report are generally intact and in good condition. Intact and undisturbed asbestos containing building materials do not pose a health risk to the building occupants. Disturbing the material improperly however, could expose the building occupants to airborne asbestos fibers. West Coast Safety Consultants recommends all the asbestos containing materials identified in this report be maintained in their current condition and removed prior to demolition, renovation or any activity which could disturb those materials by an asbestos abatement contractor licensed by the State of California. If additional suspect materials are discovered during demolition or renovation activities, the material should be assumed to contain asbestos until sampling proves otherwise. Estimated quantities of asbestos containing material identified in this report are intended as estimates only. Prior to removal of asbestos containing materials, West Coast Safety Consultants recommends the contractor make a thorough site investigation to independently ascertain the actual quantities prior to submitting a price quote. These conclusions and recommendations are based on the requirements set forth in 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAP), and Title 8, Chapter 4, Paragraph 1529, the Asbestos Standard of the California Occupational Safety and Health Administration. CLOSURE The findings and conclusions rendered in this report are opinions based on the scope of work authorized by the client and laboratory analysis of building material samples collected during this inspection. This report does not reflect variations which may exist between sampling points. These variations cannot be anticipated, nor could they be entirely accounted for, in spite of exhaustive additional testing. Our work has been performed in accordance with generally accepted practices in the field of asbestos consultation. No other warranty, either expressed or implied is made. Although every effort is made to identify all the asbestos containing materials in a building, it is possible for asbestos containing materials which are located under sub-floors, behind walls or otherwise hidden from view to go undetected until demolition or renovation activities uncover the material. If additional suspect materials are discovered, West Coast Safety Consultants will collect samples and provide a report for no additional cost other than the laboratory fee for sample analysis. Enclosed with this report is a sample result summary, sample location diagram, laboratory report from Forensic Analytical Services and a copy of my asbestos certification. I appreciate this opportunity to be of service. Should you have any questions or comments regarding this report, please contact this office at your convenience.

The inspection was conducted for CAL-OSHA and EPA compliance in conjunction with the renovation/demolition of the structure. All accessible areas were visibly inspected and representative samples of suspect materials were obtained and analyzed. Samples were not collected from every painted surface, however samples were obtained which represent the majority of the painted surfaces inside and outside the building. LEAD SAMPLE ANALYSIS Our survey involved a visual inspection of the structure and sample collection from painted surfaces. The samples analyzed by Forensic Analytical Specialties using Flame Atomic Absorption in accordance with the Environmental Protection Agency (EPA) Method (3050B/7420) to identify lead content. Forensic Analytical Specialties, Incorporated is a laboratory which is certified to analyze for lead. They are accredited by the American Industrial Hygiene Association, the National Institute of Standards and Technology, and the California Department of Public Health (CDPH). Please note the attached laboratory report. 4581 Wavertree Street $ San Luis Obispo, CA 93401 $ Phone (805) 748-8832 2 LEAD FINDINGS West Coast Safety Consultants visual inspection indicated the majority of the painted surfaces on the interior of the building were intact and in good condition. Areas with flaking and peeling paint were observed on the interior office ceiling, office floor, exterior walls and fascia. A total of 13 samples were collected and analyzed for lead content. The results in parts per million (ppm) are as follows: Sample# Location Description Lead Content GR-101 Office Drywall Wall Beige Paint 680 ppm GR-102 Office Block Wall Beige Paint None Detected GR-103 Office Wood Ceiling Beige Paint 40,000 ppm* GR-104 Office Wood Window Frame Beige Paint 3,600 ppm GR-105 Office Metal Door Frame Beige Paint 1,100 ppm GR-106 Office Concrete Floor Brown Paint 12,000 ppm* GR-107 Office Metal Post Beige Paint 300 ppm GR-108 Exterior Block Wall Green Paint None Detected GR-109 Exterior Wood Eave Brown Paint 1,800 ppm GR-110 Exterior Wood Wall Brown Paint 3,500 ppm GR-111 Exterior Wood Fascia Green Paint 490 ppm GR-112 Exterior Wood Door Green Paint 22,000 ppm GR-113 Exterior Metal Post Green Paint 1,600 ppm *Denotes Lead Hazard As a comparison, the EPA and CDPH consider a material to be lead based paint when it exceeds .5% or 5,000 ppm. In addition, the Consumer Product Safety Commission (CPSC) set a limit of .009% or 90 ppm of lead in paint for children=s toys and CAL-OSHA regulates workers who disturb lead coated surfaces at any detectable lead level. WEST COAST SAFETY CONSULTANTS 3 SUMMARY No lead was detected in the samples collected from the interior and exterior painted cinder block walls. Low levels of lead (less than 1,000 ppm) were detected in the samples collected from the following building components: 1. Interior Drywall Walls 2. Interior Metal Posts 3. Exterior Wood Fascia Moderate levels of lead (1,000 – 3,600 ppm) were detected in the samples collected from the following building components: 1. Interior Door Frames 2. Interior Window Frames 3. Exterior Wood Walls 4. Exterior Wood Eaves 5. Exterior Metal Posts High levels of lead (above 5,000 ppm) were detected in the samples collected from the following building components: 1. Interior Wood Ceiling 2. Interior Concrete Floor 3. Exterior Doors High levels of lead were detected on the interior painted concrete floor and wood ceiling. These materials were damaged and flaking and peeling paint was observed. Damaged painted surfaces containing more than 5,000 ppm lead are considered a lead hazard by the EPA and CDPH . West Coast Safety Consultants recommends any contractor conducting work which will disturb painted surfaces receive notification of the lead content and the condition of the lead containing surfaces prior to demolition, renovation, or any activity which would disturb the material. All work should be conducted in compliance with the CAL-OSHA and EPA regulations. CLOSURE The findings and conclusions rendered in this report are based on the scope of work authorized by the client and laboratory analysis of building material samples collected during this inspection. This report does not reflect variations which may exist between sampling points. These variations cannot be anticipated, nor could they be entirely accounted for even with exhaustive testing. All work has been performed in accordance with generally accepted practices in the field of lead consultation. WEST COAST SAFETY CONSULTANTS 4 The conclusions and recommendations listed in this report are based on the requirements set forth in the Department of Housing and Urban Development Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAP), and Section 1532.1 the Lead Standard of the California Occupational Safety and Health Administration.
