          The following is an Asbestos and Lead Survey Report summarizing observations and
          laboratory analytical results obtained by Mr. Remington Caldwell, California Certified
          Asbestos Consultant (CAC) and California Certified Lead Inspector with RGA
          Environmental, Inc. (RGA). The survey was conducted on May 12 and 13, 2011 of
          designated areas of planned renovation (plus associated roofs) at the Los Medanos
          College, in Pittsburg, California. The scope of the survey was to identify hazardous
          materials (asbestos, lead, mercury, and PCBs that might become a worker safety hazard
          or require special handling/waste disposal if disturbed during phased renovation
          construction activities planned under the following descriptions:

          Asbestos Survey Results

          During the survey, fifty-four (54) samples were collected of forty (40) homogenous areas
          of suspected asbestos containing material (ACM) observed within the survey areas.
          Based on site observations and a review of the laboratory analytical report, the following
          approximate quantities of ACM (>1% asbestos content) are present among the three
          buildings involved in the planned renovations:

                    Student Services Building
                    • 16,000 square feet of asphalt roofing under gravel
                    • 100 square feet adhesive behind chalk board in 2nd Floor English (assumed)
                    • 400 square feet flooring (2 layers) with black mastic – Business Services

          Lead in Paint Survey Results

          During the survey, a total of five paint chip samples of predominant paints and coating
          were submitted to a certified laboratory for analysis of lead content. Of the five samples
          submitted and analyzed, the laboratory reported no lead detected above the limit of
          detection of the analytical method. The orange paint on the metal ventilation ducting and
          the paper-wrap of the fiberglass pipe insulation attached to the open concrete ceilings
          within the Student Services Building have been previously tested by RGA (Asbestos and
          Lead Survey dated April 20, 2011) and classified as lead containing.

          Table V, provided in Appendix B, summarizes the laboratory analytical results reported
          for suspected lead containing predominant paints and coatings observed and sampled in
          the scheduled renovation areas. Copies of paint chip sample analytical laboratory reports

               2. Scope of Work

               The scope of the survey was:
          •    Conduct an asbestos survey and limited testing for lead for the purpose of renovation
               of the Student Services Building, Student Life Relocation Building, and the Office of
               Instruction Building areas on the Los Medanos College campus, 2700 East Leland
               Road in Pittsburg, California.

          •    Collect a representative number of samples of suspect ACMs following the National
               Emissions Standard for Hazardous Air Pollutants (NESHAPs) protocol for sample
               collection for a demolition/renovation survey. Analyze asbestos bulk samples using
               polarized light microscopy (PLM) in accordance with EPA’s July 1993 method for
               the determination of asbestos in bulk building materials - EPA 600/R-93/116.

          •    Collect samples of bulk materials and paint chips of the primary painted surfaces
               suspected to be lead containing for purposes of compliance with California
               Department of Occupational Safety and Health (DOSH) Lead in Construction
               Standard. Bulk samples and paint chips were analyzed at an accredited laboratory by
               Flame Atomic Absorption (AA) for Total Lead reported in parts per million (ppm).

          •    Submit written report including analytical results, regulatory requirements, a diagram
               of sample locations, conclusions and recommendations.

               3. Methods and Sampling Strategy

               Visual Inspection
          Accessible building materials were visually inspected using the methods 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) and Asbestos School
          Hazard Abatement and Reauthorization Act (ASHARA) have adopted the AHERA
          sampling methodology for all buildings subject to demolition or renovation.

               Bulk Sampling of Asbestos
          Bulk samples of all suspect ACM homogeneous materials were collected. A
          homogeneous material is defined as a surfacing material, thermal system insulation, or
          miscellaneous material that is uniform in color, texture and age of construction. Examples
          of homogeneous materials include:
               •    Pipe-insulation produced by the same manufacturer and installed during the same
                    time period;
               •    Resilient flooring of identical color and pattern;
               •    Troweled on surfacing materials located in contiguous areas.

          The building was visually inspected for the presence of suspect materials. As materials
          were identified, bulk samples were obtained with the aid of a coring device or other hand
          tool and placed into individual sampling bags. Each sample was given a discrete
          identification number and recorded on field notes as well as chain-of-custody forms.
          Refer to accompanying tables and appendices for details on material sample locations and
          results. Bulk samples were transported to RGA Environmental, Inc. (RGA) in Seattle,
          Washington.

               Bulk Sampling of Suspect Lead Containing Materials
          Paint chip and/or suspected lead containing materials were collected using a hand scraper
          and were placed into individual plastic sampling containers. Each sample was provided a
          discreet sample number, which was recorded on a chain-of-custody form. The samples
          were then sent to LA Testing.


               Bulk Sample Analysis - Asbestos
          RGA is accredited under the National Institute of Standards and Technology's National
          Voluntary Laboratory Accreditation Program (NVLAP) for determination of asbestos
          fibers in bulk materials.

          All samples were analyzed using polarized light microscopy (PLM) techniques in
          accordance with methodology approved by the U.S. Environmental Protection Agency
          (EPA). As set forth in the Code of Federal Regulations, 40 CFR Part 763, Appendix A to
          Subpart F, Section 1.2 and 1.7.2.4, the lower limit of reliability detection for asbestos
          using the PLM method is approximately one percent (1%) by volume. Cal-OSHA defines
          asbestos containing construction materials (ACCM) as those materials having asbestos
          content of greater than one tenth of one percent (>0.1%).

          When None Detected (ND) appears in this report, it should be interpreted as meaning no
          asbestos was 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 tests
          positive for asbestos, all homogeneous materials within that building are considered to be
          asbestos containing.

               Bulk Sample Analysis – Lead
          All paint and suspect materials samples were analyzed for lead content using the Flame
          Atomic Absorption spectroscopy in accordance to EPA Method SW846-3050B-7420.
          When “<” appears in the lead sample report, it should be interpreted as meaning below
          analytical detection limit.

               Miscellaneous Hazardous Materials
          During the survey, RGA observed 2-foot and 4-foot long fluorescent light tubes used to
          provide primary lighting throughout the areas of planned renovation. Fluorescent light

          tubes are assumed to each contain a small amount of mercury vapor and require special
          packaging prior to recycling. A representative number of fluorescent light ballasts were
          inspected and observed to possess labels displaying the words “NO PCBs.”


               4. Asbestos Results

          During the survey, fifty-four (54) bulk samples were collected of forty (40) homogeneous
          suspected ACM from among the planned renovation areas of the three building surveyed.
          Based on site observations and a review of the laboratory analytical report, the following
          approximate quantities of ACM (>1% asbestos content) are present at the subject sites:

          Student Services Building
                 • 16,000 square feet of asphalt roofing under gravel
                 • 6,000 square feet of light weight roof concrete (residue from tar above)
                 • 100 square feet adhesive behind chalk board in 2nd Floor English (assumed)
                 • 400 square feet flooring (2 layers) with black mastic – Business Services
                     hallways

          Student Life Relocation Building (No ACM detected)

          Office of Instruction
                 • 100 lineal feet of HVAC duct tape with silver paint (roof)
                 • 1 each sink with black coating (Kitchen)

          Tables I-IV summarizing the laboratory analytical results reported for suspected ACM
          observed and sampled in the scheduled renovation areas are provided in Appendix A.
          Copies of asbestos sample analytical laboratory reports and associated chain of custody
          forms are also provided in Appendix A.


               5. Lead Results

          During the survey, five (5) paint chip samples were collected of suspected lead
          containing paint. Paint chip samples were collected from the predominant paints
          observed on building components associated with the structure areas to be renovated.
          The orange paint on the metal ventilation duct system and pipe insulation attached to the
          open ceilings of the Student Services Building are assumed to be lead containing based
          on a previous RGA lead in paint survey conducted in adjacent areas (April 20, 2011).

          Table V, provided in Appendix B, summarizes the laboratory analytical results reported
          for suspected lead containing predominant paints and coatings observed and sampled in
          the scheduled renovation areas. Copies of paint chip sample analytical laboratory reports
          and associated chain of custody forms are also provided in Appendix B.

               6. Regulatory Requirements

               Asbestos

          Asbestos-containing building materials at the building contain asbestos in concentrations
          greater than one tenth of one percent (0.1%). Impacting materials containing greater than
          0.1% asbestos either through repair, maintenance, renovation or demolition activities
          triggers numerous regulations enforced by such agencies as OSHA (worker protection)
          and EPA (environmental exposure, transportation and disposal).

          Listed below are the regulations that apply if the materials are removed:

          •    Any individual who contracts to provide health and safety services relating to ACMs
               must be certified by Cal-OSHA as either a Certified Asbestos Consultant or a Site
               Surveillance Technician. The activities they are certified to provide include:
               conducting asbestos surveys; writing work plans or specifications for abatement;
               monitoring the work of abatement contractors; collecting air samples; and
               determining if the work area is safe for re-occupancy by non-asbestos workers.
               Regulation: Cal-OSHA 8 CCR 1529 (q) (1).

          •    If more than 100 square feet of materials that contain greater than 0.1% asbestos will
               be abated, they must be abated by a Cal-OSHA registered asbestos abatement
               contractor. Regulation: Cal-OSHA 8 CCR 1529 (R).

          •    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-OSHA
               regulations. Work practices and engineering controls for Class II work are specified
               in Cal-OSHA 8 CCR 1529 (g) (7-8).

          •    Friable ACMs greater than 1% asbestos must be manifested, transported, and
               disposed of as hazardous waste in accordance with the Department of Toxic and
               Substances Control (DTSC), a division of Cal-EPA. DTSC regulates disposal of
               asbestos waste. DTSC issues U.S. EPA hazardous waste generator identification
               numbers.

               Lead-Containing Materials

          Lead-containing paint was previously identified on the exposed painted HVAC ducting
          and painted paper-wrap of the fiberglass TSI pipe insulation. Impacting lead-containing
          materials either through renovation or demolition activities triggers numerous regulations
          enforced by such agencies as OSHA (worker protection), EPA (environmental exposure,
          transportation and disposal), and Department of Health Services (DHS).

          Listed below are the lead-containing paint regulations that apply if the paint is removed
          or painted building components are impacted during demolition activities:

          •    The Federal Occupations Safety and Health Administration (OSHA) as well as
               California OSHA regulate all worker exposure during construction activities that
               impact lead-containing materials.        OSHA enforces the Lead Exposure in
               Construction; Interim Final Rule found in 29 CFR Part 1926.62 and CAL-OSHA
               Title 8 CCR 1532.1. The scope covers construction work where employees may be
               exposed to lead during such activities as demolition, removal, surface preparation for
               re-painting, renovation, clean-up and routine maintenance. The OSHA specified
               method of compliance includes respiratory protection, protective clothing and
               equipment, housekeeping, hygiene facilities, medical surveillance, training, etc.

          •    California OSHA requires Department of Heath Services Lead-Related Construction
               training if any lead related construction work in public buildings will exceed OSHA’s
               permissible exposure limit (PEL) for lead.

          •    Disposal of all lead-containing materials are regulated at concentrations at or
               exceeding 350 ppm as stated in 40 Code of Federal Regulations (CFR) Part 263 -
               Land Disposal Regulations and Title 22, Division 4 Environmental Health of the
               California Administrative Code.        However, lead related work at any lead
               concentration is regulated under the Occupational Safety and Health statutes.


               7. Recommendations to Implement Regulatory Requirements

               Asbestos

          •    Revise the existing performance abatement specification developed for the adjacent
               Student Services area to include the types and estimated quantities of ACM reported
               in this survey. The purpose of an abatement specification is to clearly define the
               scope of work for more competitive and accurate bidding as well as to reduce the
               number of costly delays and change orders during the project.

          •    Retain a Certified Asbestos Consultant or Site Surveillance Technician to provide on-
               site construction supervision of the asbestos abatement contractor to ensure utilization
               of proper work practices as stated in the work plan or specification. The Consultant
               also ensures that all local, state and federal regulations are followed and that the
               project remains on schedule. The on-site Consultant generates documentation of
               contractor work practices and training, and asbestos air sampling results. The on-site
               Consultant also ensures that all asbestos materials are removed by the abatement
               contractor and properly manifested.

          •    Request the Asbestos Consultant to collect a sufficient number of air samples on a
               daily basis to validate that the abatement contractor is not causing any releases of
               airborne asbestos fibers outside their work area.

          •    Request the Asbestos Consultant to visually review the work of the abatement
               contractor to verify that all the ACMs are abated. If the work areas pass the visual

               clearance, then final air clearance samples are collected to ensure that the area is safe
               for re-occupancy, or unregulated work.

          •    The College should provide notification to employees, contractors, subcontractors,
               and staff at the site structures as to the presence, location, and quantity of ACM, LBP,
               and mercury in light tubes within 15 days of receiving this information.

          •    All ACM present in/on site structures should be removed prior to disturbance by
               construction activities by a properly licensed asbestos abatement contractor
               employing only properly trained and currently certified asbestos personnel who apply
               appropriate work practices in accordance with current local, State, and Federal
               asbestos regulations

          •    Prior to future work at the site that may disturb asbestos in “any amount”, Cal-OSHA
               requires advanced written notification from the subject contractor of their “Intent to
               Conduct Asbestos Related Work.”

          •    A 10 working day advance written notification and payment of appropriate fees are
               required by the Bay Area Air Quality Management District (BAAQMD) for every
               demolition project within their jurisdiction, even when no ACM is present, and for
               each renovation project where the amount of friable ACM is equal to or greater than
               160 lineal feet or 260 square feet.

          •    Contractors disturbing lead-based and lead-containing paint should implement
               appropriate lead related work practices in accordance with applicable Cal-OSHA
               worker exposure regulations to include, at a minimum of lead awareness training for
               all site workers and provision of hand-washing stations at the work site.

          •    Contractors disturbing lead-based paint on building components must do so in
               compliance with applicable regulations of California Department of Occupational
               Safety and Health, including the submission of an advance notification to the local
               Cal-OSHA office of their “Intent to Conduct Lead-Related Construction Activity.”

          •    Remove any peeling, stratified or blistered lead-containing paint. Stabilize existing
               lead containing paint to reduce paint from peeling or separating from the substrate
               prior demolition.

          •    Contractor should adhere to OSHA and other applicable state and local regulations
               for worker protection, hazard communications, work practices, engineering controls
               and proper waste disposal.
          •    Proper waste stream categorization is required for the disposal of lead-containing
               materials such as paint debris, ceramic tile, and painted building components (intact)
               in accordance with the Department of Toxic Substance Control (DTSC). The
               disposal of lead-containing materials shall be coordinated with the landfill.
