2.0 INTRODUCTION

Millennium conducted an asbestos survey for the Fresno VA in accordance with RFP VA261-12-R- 1059 from September 17, 2012 through October 19, 2012. The Fresno VA campus is located at 2615 E. Clinton Avenue, Fresno, CA. The survey included multiple buildings throughout the campus. The buildings included the scope of the asbestos survey are: Buildings 1-8, 15-19, 22, 24, 31, 32, 34, OPC and select exterior underground pipe chases. The final results of the survey will provide a means for the Fresno VA to more efficiently plan for repairs, renovations and demolition projects.

2.1 SCOPE OF WORK

The scope of work for the project included the submission of nine (9) deliverable items. The required submittals and their approval dates included:

1. Pre-Survey Report - Submitted for Approval on August 31, 2012

2. QA/QC Plan – Approved 09/14/2012

3. Health and Safety Plan – Approved 09/14/2012

4. Employee Certifications – Approved 09/14/2012

5. Drawing Criteria - Pending

6. Project Schedule – Approved 09/14/12

7. Schedule of Values – Approved 08/23/12

8. Survey Report - Pending

9. Drawings - Pending

The asbestos survey tasks included reviews of historical records and data, site visits, collection of representative samples, assessment of the condition of the materials, and quantification of the asbestos-containing materials throughout the specified buildings. In accordance with the project requirements, samples were not taken if it rendered the material unstable, had the potential to cause leaking or other deterioration of the base material or if the sampling posed a hazard to those working in and around the building.

The reporting requirements also include sample location maps in AutoCAD format, indexed schedule of samples and pertinent notes, and a narrative on the methodology of the survey.

2.2 SAMPLING METHODS, PROCEDURES AND PERSONNEL

A detailed sampling and analysis plan was prepared prior to the site survey. These sample collection and handling procedures were provided in the Quality Assurance Project Plan (QAPP) dated September 7, 2012. In summary of the QAPP, the asbestos survey was performed using general procedures and protocols defined in EPA 40 CFR, part 763.

The asbestos analyses were performed at an independent 3rd party accredited laboratory using the EPA 600/R-93/116 method. Additional confirmation analyses were not performed in accordance with the project requirements (e.g., point counting and transmission electron microscopy). All locations within the scope of work were physically inspected and categorized (i.e., AHERA and NESHAP categories), homogeneous area-by homogeneous area, to determine the presence of ACM.

Millennium personnel held valid Cal/OSHA licenses for the respective type of work they performed. These asbestos specific licenses include: Certified Asbestos Consultants (CAC) and Site- Surveillance Technicians (SST). The field staff and their respective certifications that performed site assessment activities are:

1. Mr. Jeremy Malson (CAC No. 07-4183)

2. Mr. Wes Chase (CAC No. 12-4846),

3. Mr. Kevin Milani (CSST No. 06-4035),

4. Ms. Nichole D’Ottavio (CSST No. 11-4803),

5. Mr. Tyler Belair (CSST No. 11-4744), and

6. Mr. Ramil Arcia (CAC No. 10-4613).

2.2.1 Review of Procedures: Asbestos Inspection, Bulk Sampling, Laboratory Information and Risk Assessment

The asbestos inspection and bulk sampling procedures were based on the guidelines established by the U.S. EPA in the Guidance for Controlling Asbestos Containing Materials in Buildings, Office of Pesticides and Toxic Substances, DOC #560/5-85-024 and 40 CFR Part 763, Asbestos Hazard Emergency Response Act (AHERA). Field information is organized according to the AHERA concept of Homogeneous Areas (HA). A HA is defined as a suspect material of similar age, appearance, function, and texture. Each material will be grouped together as a specific HA, sampled, and then assessed for condition. The AHERA guidelines represent an industry standard sampling protocol and as such was utilized during the inspection and sampling. For the purposes of this inspection, suspect ACM has been placed in three (3) material categories:

1. Thermal Systems Insulation (TSI);

2. Surfacing Materials; and

3. Miscellaneous Materials.

The locations within the buildings were physically inspected on a functional space-by-functional space and homogeneous area-by-homogeneous area basis, to determine the presence of ACM. Core samples of friable and non-friable suspect materials were collected by penetration of the suspect material to its substrate. The bulk samples collected were placed in individual sealed containers and labeled with unique sample identification numbers. Representative samples of each sampling area were then submitted to the laboratory to be analyzed for asbestos content.

Specifically, the inspection involved the following tasks:

1. Visual determination as to the extent of visible and accessible suspect materials and conditions of the material;

2. Collection and analyses of suspect building materials for asbestos content;

3. Determining condition (i.e., friable or non-friable) of suspect materials by physically touching, assessing, and placing the material into the correct ACM category (i.e., Physical Condition Assessment);

4. Quantification of the amount of suspect friable and non-friable materials along with their location;

5. Identification of all suspect materials sampled on the appropriate building floor plan diagram with the sample number; and

6. Preparation of a Chain-of-Custody form that accompanied the samples to the laboratory.

The U.S. EPA AHERA specifies that a physical assessment of all friable suspect material must be performed during the inspection. The suspect materials are assessed to determine if they pose a hazard, and if so, they are then ranked according to risk. The physical condition assessment consists of determining the condition of the ACM, the probable cause of damage, and the potential for future disturbance. AHERA lists seven categories in which to assess the current condition and potential for damage. These categories are as follows:

1. Damaged or Significantly Damaged Friable Thermal System Insulation;

2. Damaged Friable Surfacing Material;

3. Significantly Damaged Friable Surfacing Material;

4. Damaged or Significantly Damaged Friable Miscellaneous Material;

5. ACM with potential for damage;

6. ACM with the potential for significant damage; and

7. Any remaining Friable ACM or Assumed Friable ACM.

Additionally, as part of the assessment and categorization of materials, the ACMs are further defined by the current condition of the ACM, the potential for future damage, and a friability rating. These are defined as follows:

1. Current Condition of ACM: A ranking system using a scale of 1-7 was used to evaluate the current condition of ACMs. A rank of "1" means the material is in "poor" condition and requires top priority for correcting the hazard risk. A result of "5" would indicate material in "fair" condition with moderate potential for future damage, which typically requires corrective actions. A rank of "7" indicates material in "good" condition with low potential for future damage; category 7 areas have a low hazard risk. The criteria for determining the fair and poor condition are as follows:

a. Fair: The overall damage is up to ten percent (≤10%) and/or any localized damage is up to twenty-five percent (≤25%).

b. Poor: The overall damage is greater than ten percent (>10%) and/or any localized damage is greater than (>25%).

2. Potential for Future Damage of ACM: Another step in the assessment process is to determine the potential for future damage or deterioration for material classified as good or fair. The potential for future damage was classified as High, Moderate, or Low. There are many factors to consider in determining whether or not there is potential for future damage. Some of these factors may include potential for physical contact and the influence of environmental factors such as vibration, air erosion, the likelihood of water damage, etc.

3. Friability Rating: All material were given a friability rating and classified as either Friable ACM or Non-Friable ACM. Friable ACM is defined as any material that contains more than one percent (>1%) asbestos and can be crumbled, pulverized, or reduced to powder by hand pressure. It is a description of risk and refers to a material’s likeliness to release airborne fibers.

Chain-of-Custody procedures and records provide a means of tracing each sample from the time of collection through the shipment and final analyses. Proper Chain-of-Custody procedures also provide a written record of all persons handling the samples. The information necessary to relate sample locations for reporting purposes is documented with each sample. This information is essential to proper completion of a sample results report and typically includes client and facility information; unique sample identification number; date and time sampled; sampler name and signature; sample location including the room/area; and field sketches of sample locations.

All sample analyses were performed by EMSL Analytical, Inc., San Leandro, CA, a laboratory which is certified by the State of California Environmental Laboratory Accreditation Program (CA ELAP No. 1620), the U.S. Department of Commerce, National Institute of Standards and Technology (NIST) Proficiency Analytical Testing (PAT No. 10178) program, and is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP No. 101048-3) for bulk asbestos analyses.

The laboratory will be requested to retain the samples for at least ninety (90) days in the event re-analyses of samples are required. All disposal of samples will be compliant with established Federal, state, and local regulations.

3.0 SITE HISTORY AND BUILDING SUMMARY

The United States has the most comprehensive system of assistance for veterans of any nation in the world. The VA health care system has grown from 54 hospitals in 1930, to include 152 hospitals;

800 community based outpatient clinics; 126 nursing home care units; and 35 domiciliaries. VA health care facilities provide a broad spectrum of medical, surgical, and rehabilitative care. This project includes the Fresno VA Medical Center.

The Fresno VA has conducted considerable remodeling of various buildings and areas, particularly in the main hospital (i.e., Building 1, ca. 1949). Three large remodel projects including the entire 4th floor of Building 1, the east wing of the 6th floor in Building 1, and the basement of the Outpatient Clinic (OPC) were fully renovated. A site-wide thermal system insulation (TSI) abatement project was completed in 2010. This project included the removal of accessible asbestos-containing TSI.

Similarly, other buildings on the campus, which are part of this contract, have undergone multiple renovations since their original construction. The detailed list of buildings and areas included in the project are as follows:
