1. Executive Summary
The following is a report of the limited hazardous materials survey report conducted by Mr.Mike Bishop and Mr. William Frieszell, Certified Asbestos Consultants (CACs) and State ofCalifornia Department of Public Health (CDPH) Lead Professionals with RGAEnvironmental, Inc. (RGA). The survey was performed on August 15, 2014 at the DiabloValley College Campus located at 321 Golf Club Road in Pleasant Hill, California. Thesurvey scope was limited to the materials with the potential to be impacted during the D-1037 Library Classroom Project.
Twenty-eight (28) homogeneous suspect asbestos-containing materials (ACMs) wereidentified during the survey. Five (5) of the materials sampled tested positive for asbestoscontent. In addition, one (1) material was assumed to be asbestos containing. Table I inSection 4 of this report provides a summary of the ACMs identified and the general materiallocations.
Five (5) paint and one (1) ceramic tile sample was collected from interior and exteriorsurfaces. Two (2) paint and the ceramic tile sample were found to contain detectable levelsof lead. None of the samples were analyzed and found to have lead concentrations greaterthan the lead-based threshold of 5,000 parts per million (ppm). Table III in Section 5 of thisreport provides a summary of the results of the lead sampling.
Three (3) suspect polychlorinated biphenyls (PCB) containing materials were collected andanalyzed during the survey. None of the materials sampled were above the laboratorydetection limit. Table IV in Section 6 of this report provides a summary of the PCBsampling results.
2. Scope of Work
The scope of the survey was as follows:
· Inspect the areas scheduled for renovation in the D-1037 Library Classroom Project forthe presence of suspect ACMs, lead-containing paint, mercury containing products andpotential PCB-containing materials.
Limited Hazardous Materials Survey ReportD1037 Library Classroom projectPleasant Hill, CA
· Collect a representative number of samples of suspect ACMs following a NationalEmissions Standards for Hazardous Air Pollutants (NESHAPS) protocol for samplecollection for a demolition/renovation survey. Asbestos bulk samples were analyzedusing polarized light microscopy (PLM) in accordance with EPA’s July 1993 method forthe determination of asbestos in bulk building materials - EPA 600/R-93/116.
· Provide a certified lead professional to collect bulk samples of paint and other buildingmaterials suspected to be lead-containing. Bulk samples were analyzed at an accreditedlaboratory by Flame Atomic Absorption (AA) for Total Lead reported in parts per million(ppm).
· Collect bulk samples of suspect PCB containing materials. Bulk PCB samples wereanalyzed in accordance with EPA method SW8082.
· Submit written report including analytical results, regulatory requirements, conclusionsand recommendations.
3. Methods and Sampling Strategy
Visual Inspection
Accessible building materials on the interior of the building were visually inspected using themethods presented in the federal Asbestos Hazard Emergency Response Act (AHERA)regulations (40 CFR, Part 763) as a guideline. AHERA was originally only applicable to schools,however State and Federal Occupational Safety and Health Administration (OSHA) andAsbestos School Hazard Abatement Reauthorization Act (ASHARA) have adopted the AHERAsampling methodology for all buildings subject to demolition or renovation.
Visual Inspection for Mercury Containing MaterialsFluorescent light tubes (mercury containing) were found to be the dominant light source withinsurvey area. All light tubes should be handled without breakage prior to removal of any of thefixtures. RGA observed approximately three-hundred fifty (350) four-foot long mercurycontaining light tubes within the survey area.
Visual Inspection for PCB-containing EquipmentFluorescent light ballasts were also observed inside the building. All ballasts should be inspectedprior to disposal to verify the presence/absence of PCBs. Ballasts should be assumed to be PCB-containing unless specifically marked by the manufacturer’s label as containing “No PCBs”.RGA observed approximately two-hundred (200) possible PCB-containing light ballasts withinthe survey area.

Bulk Sampling of Suspect Asbestos MaterialsBulk samples of suspect ACMs were collected from each homogeneous material. Ahomogeneous material is defined as a surfacing material, thermal system insulation, ormiscellaneous material that is similar in size, color, texture and age of construction. Examples ofhomogeneous materials include:
· Pipe-insulation produced by the same manufacturer and installed during the same timeperiod;
· Resilient flooring of identical color and pattern;
· Troweled on surfacing materials with similar textures.
The survey area was visually inspected for the presence of suspect materials. As materials wereidentified, bulk samples were obtained with the aid of a coring device or other hand tool andplaced into individual sample containers. Each sample was given a discreet identification numberand recorded on field notes as well as chain-of-custody forms. Refer to Table I below andAppendix 1 for details on material sample locations and analytical results.
Bulk Sampling of Lead PaintBulk lead samples were collected using a hand tools and were placed into individual samplingcontainers. Each sample was provided a discreet sample number and was recorded on achain-of-custody form. Refer to Table III below and Appendix 2 for details on sample locationsand analytical results.
Bulk Sampling of Suspect PCB MaterialsBulk PBC samples were collected using a hand tools and were placed into individual samplingcontainers. Each sample was provided a discreet sample number and was recorded on achain-of-custody form. Refer to Table IV below and Appendix 3 for details on sample locationsand analytical results.
Bulk Sample Analysis – AsbestosThe samples were transported under chain-of-custody procedures to RGA’s laboratory in Seattle,Washington. RGA is accredited by the National Institute of Standards and Technology'sNational Voluntary Laboratory Accreditation Program (NVLAP) and by the CaliforniaDepartment of Health Services, Environmental Laboratory Accreditation Program (CALELAP)for bulk asbestos analysis.
All samples were analyzed using polarized light microscopy (PLM) techniques in accordancewith methodology approved by the U.S. Environmental Protection Agency (EPA). As set forth inthe Code of Federal Regulations, 40 CFR Part 763, Appendix A to Subpart F, Section 1.2 and1.7.2.4, the lower limit of reliability detection for asbestos using the PLM method isapproximately one percent (1%) by volume. Cal-OSHA defines asbestos containing construction
Limited Hazardous Materials Survey ReportD1037 Library Classroom projectPleasant Hill, CA
materials (ACCM) as those materials having an asbestos content of greater than one tenth of onepercent (>0.1%).
When None Detected (ND) appears in this report, it should be interpreted as meaning no asbestoswas observed in the sample material above the reliable limit of detection for the PLM method.
Note: under EPA assessment criteria, if a single sample of a homogeneous material test positivefor asbestos, then the entire area of that homogeneous material throughout the building isconsidered to be asbestos containing.
Bulk Sample Analysis - LeadThe samples were transported under chain-of-custody procedures to RGA’s laboratory in Seattle,Washington. RGA is accredited by the American Industrial Hygiene Association’s (AIHA’s)Environmental Lead Laboratory Accreditation Program (ELLAP) for the analysis of lead in paintchips, dust wipes, and/or soil.
All paint samples were analyzed for lead content using the Flame Atomic Absorptionspectroscopy (FLAA) in accordance to EPA Method SW846-7420. When “<” appears in the leadsample report, it should be interpreted as meaning below analytical detection limit and no leadwas detected in the paint sample.
Bulk Sample Analysis - PCBsThe samples were transported under chain-of-custody procedures to McCampbell Analytical,Inc. (McCampbell) in Pittsburg, California. McCampbell analyzed the PCB bulk samples inaccordance with EPA method SW8082.
4. Asbestos Results

7. Regulatory Requirements
Asbestos
Asbestos-containing building materials at the subject facility contain asbestos inconcentrations of greater than one percent (1.0%). Impacting materials containing greaterthan 1.0% asbestos either through repair, maintenance, renovation or demolition activitiestriggers numerous regulations enforced by such agencies as OSHA (worker protection) andEPA (environmental exposure, transportation and disposal). Cal-OSHA regulates asbestosat concentrations greater than one tenth of one percent (0.1%).
Listed below are the regulations that apply if the materials are removed or managed in-place:
· Any individual who contracts to provide health and safety services relating to asbestos-containing materials must be certified by Cal-OSHA as either a Certified AsbestosConsultant or a Site Surveillance Technician. The activities they are certified to provideinclude: conducting asbestos surveys; writing work plans or specifications for abatement;monitoring the work of abatement contractors; collecting air samples; and determining if
Limited Hazardous Materials Survey ReportD1037 Library Classroom projectPleasant Hill, CA
the work area is safe for re-occupancy by non-asbestos workers. Regulation: Cal-OSHA8 CCR 1529 (q)(1).
· Notify employees, tenants and contractors who perform work in the building of thepresence, locations and quantities of asbestos in accordance with California Health andSafety Code Section 25915 and Proposition 65, California (8 CCR 1529 (k)) and FederalOSHA (1926.1101) regulations.
· If more than 100 square feet of materials that contain greater than 0.1% asbestos will beremoved, the materials must be removed by a registered asbestos abatement contractor.Regulation: Cal-OSHA 8 CCR 1529 (R).
· If more than 100 square feet or 100 linear feet of friable ACM will likely be removed, theabatement contractor must notify the local Air Quality District ten (10) days prior toremoving the material. Regulation: National Emission Standards for Hazardous AirPollutants {NESHAPS – 40 CFR Part 61}.
· ACMs that are classified by OSHA as surfacing/thermal system insulation are present.Removal of these materials is considered a Class I Activity according to Cal-OSHAregulations. Work Practices and engineering controls for Class I Work are specified inCal-OSHA 8 CCR 1529 (g) (4-6)
· ACMs that are classified by OSHA as other/miscellaneous materials are present.Removal of these materials is considered a Class II activity according to Cal-OSHAregulations. Work practices and engineering controls for Class II work are specified inCal-OSHA 8 CCR 1529 (g) (7-8).
· Friable ACMs greater than 1% asbestos must be manifested, transported, and disposed ofas hazardous waste in accordance with the Department of Toxic and Substances Control(DTSC), a division of Cal-EPA. DTSC regulates disposal of asbestos waste. DTSCissues U.S. EPA hazardous waste generator identification numbers.
Lead
Painted surfaces observed during the survey included intact and damaged paint conditions.Impacting lead or lead-containing paint either through repair, maintenance, renovation ordemolition activities triggers numerous regulations enforced by such agencies as OSHA(worker protection), EPA (environmental exposure, transportation and disposal), andDepartment of Public Health (DPH).
Listed below are the lead paint regulations that apply if the paint is removed:
· There are presently no federal, state or local regulations limiting the concentration of leadin public sector buildings, however several regulations established for the private sectoras well as for government subsidized housing are used industry wide as guidelines for
Limited Hazardous Materials Survey ReportD1037 Library Classroom projectPleasant Hill, CA
assessing exposure to lead. The Consumer Product Safety Commission (CPSC) has set amaximum limit of 90 ppm in paint used for residential purposes. The Department ofHousing and Urban Development (HUD) requires abatement of lead hazards involvingpaint in concentrations exceeding 5,000 ppm.
· Disposal of all lead-containing paint is regulated at concentrations at or exceeding 350ppm as stated in 40 Code of Federal Regulations (CFR) Part 263 - Land DisposalRegulations and Title 22, Division 4 Environmental Health of the CaliforniaAdministrative Code. However, lead related work at any lead concentration is regulatedunder the OSHA statutes.
· Federal OSHA as well as California OSHA regulates all worker exposure duringconstruction activities that impact lead-containing paint. California OSHA enforces theLead in Construction Standard in Title 8 CCR 1532.1. The scope covers constructionwork where employees may be exposed to lead during such activities as demolition,removal, surface preparation for re-painting, renovation, clean-up and routinemaintenance. The OSHA specified method of compliance includes respiratory protection,protective clothing and equipment, housekeeping, hygiene facilities, medicalsurveillance, and training, among other requirements.
8. Recommendations to Implement Regulatory Requirements
Asbestos
RGA recommends that the services of an environmental consultant be retained to performthe following:
· Develop a performance abatement specification for the removal of the ACMs identifiedin the survey. The purpose of abatement specifications and drawings are to clearly definethe scope of work for more competitive and accurate bidding as well as to reduce thenumber of delays and change orders during the project.
· Conduct a pre-bid job-walk for abatement contractors to obtain the most competitivepricing.
· Provide construction management including all health and safety and environmentalconstruction management such as: project bidding; review of abatement contractorsubmittals; consultation on regulatory requirements; project tracking; scheduling;attendance at progress meetings; coordination with members of the project team; andproject oversight of abatement contractor.
· Provide on-site construction supervision of the asbestos abatement contractor using aCertified Asbestos Consultant or Site Surveillance Technician to ensure utilization ofproper work practices as stated in the work plan or specification. The on-site consultantalso ensures that all local, state and federal regulations are followed and that the project
Limited Hazardous Materials Survey ReportD1037 Library Classroom projectPleasant Hill, CA
remains on schedule. The on-site consultant generates documentation of contractor workpractices, employee training, daily activities, and perimeter asbestos air sampling results.The on-site consultant also ensures that all asbestos materials are removed by theabatement contractor and properly stored, manifested and disposed.
· Collect a sufficient number of daily air samples to validate that the abatement contractoris not releasing airborne asbestos fibers outside their work area.
· Visually review the work of the abatement contractor to verify that all the ACMs areabated. If the work areas pass the visual clearance, then final air clearance samplesshould be collected to verify that the area is safe for re-occupancy.
· Write a final report outlining all activities that transpired throughout the course of theabatement project.
Lead
When lead painted surfaces are disturbed, the paint debris should be classified as hazardouswaste if lead waste concentrations exceed regulatory limits. Total lead concentration isdetermined by Total Threshold Limit Concentration (TTLC). Soluble or leachable lead isdetermined by the Soluble Threshold Limit Concentration (STLC, California required test)and/or Toxicity Characteristic Leaching Procedure (TCLP) (Federal EPA required test).Regulatory limits characterize a lead waste as a hazardous waste if lead concentrationexceeds 350 ppm by TTLC or 5 milligram per liter by STLC or TCLP.
RGA recommends the following actions prior to the start of building renovation ordemolition:
· Remove any peeling, stratified or blistered lead-containing paint prior to demolition ofpainted finish materials
· Stabilize existing paint to reduce chipping and peeling of lead containing paint.
· Use only trained workers to demolish building components with intact lead-containingpaint.
· Worker exposure and environmental monitoring and proper engineering controls shouldbe implemented throughout the lead-related work.
· Contractor should adhere to OSHA and other applicable state and local regulations forworker protection, hazard communications, work practices, engineering controls andproper waste disposal.
· Ensure proper waste stream categorization is required for the disposal of lead-containingpaint. The disposal of lead-containing materials should be coordinated with the landfill.
