Section 1 Summary

1.1 Executive Summary

This report summarizes the results of a building condition assessment (BCA) for hazardous substances used in the construction, fireproofing, and surface treatments of Bureau of Reclamation’s (BOR) Administration Building.

The Administration Building is located at 1200 Park Street, Boulder City, Nevada, on Clark County assessors parcel number 186-04-410-064. County records indicate the land is owned by USA Boulder City NV. The building is listed by BOR’s Management Services Office (MSO) under Building ID No. 0045000100B.

The assessment involved a review of BOR property records, a physical site inspection, and collection of samples for asbestos containing materials (ACM) and lead based paint (LBP). Our findings indicate that ACM and LBP were found to be in excess of regulatory or guidance levels. In the event that remodeling, renovation, or demolition of this structure is necessary, hazardous substances management practices will be required of the owner and contractors prior to and during remodeling, renovation, or demolition. Based on visual inspection, PCBs are not considered to be a possible contaminant in this building. Specific findings and recommended practices are described in detail in this report.

1.2 Authorization

The work described in this document was performed by Zenitech Environmental, LLC under order no. 04PG303334. The scope of work of this task was defined orally in meetings between representatives of BOR’s MSO and Zenitech on September 13 and October 3, 2007. Ms. Lesli Kirsch and Mr. Richard Goodale, both of BOR, provided access to the buildings.

1.3 Purpose and Customs

The purpose of a building condition assessment for hazardous substances is to ascertain whether notorious hazardous substances are present in the structure of a building. These substances are materials that pose a potential threat to human health or the environment if disturbed, such as through remodeling, renovation, or demolition.

It is customary in a BCA to research readily ascertainable building records, to conduct a physical site inspection, and to the degree judged appropriate by a qualified environmental professional, to collect and analyze samples from the building composition. The findings of these inquiries are then compared to

Page 2 Building Condition Assessment

December 14, 2007 Boulder City, Nevada existing regulatory standards and guidances, and recommendations for safe and legally required handling are presented.

It is also customary to focus the sampling and analysis on asbestos, lead in paint, and PCBs, as these are the primary hazardous substances found in building construction and are the most severely regulated. It is possible, though unlikely, that rare hazardous substances escape detection in a standard BCA.

1.4 Standard Limitations

Zenitech planned this BCA for the purpose of identifying reasonably ascertainable occurrences and impacts of elevated levels of hazardous substances in building components. This assessment was constrained to the evaluation of asbestos, lead in paint, and PCBs. The assessment of other hazardous substances, fungal contamination, or sick building syndrome was not a part of this scope of work.

Zenitech relied on visual inspection of the subject property in support of the proposed sampling locations and contaminants of interest. Zenitech assumes no liability for any loss resulting from errors or omissions arising from the use of inaccurate/incomplete information or misrepresentations made by others. Third parties who rely on this report shall do so at their own risk. This report is not licensed for open distribution on the Internet, or through other publishing means.

1.5 Certification

This BCA was prepared by a team of qualified environmental professionals meeting the definition ascribed in 40 CFR § 312.10. Additional relevant certifications of the team include EPA Certified Lead Inspector, OSHA Certified Asbestos Inspector, and hazardous materials specialists compliant with the OSHA 40-hour HAZWOPER standard.

I hereby certify that I am responsible for the services described in this document and for the preparation of the document. The services described in this document have been provided in a manner consistent with the current standards of the profession and to the best of my knowledge comply with all applicable federal, state and local statutes, regulations and ordinances.

Section 2 Background

2.1 Site Location

The Administration Building is located at 1200 Park Street, Boulder City, Nevada, on Clark County assessors parcel number 186-04-410-064. The building location is shown on the attached Figure 1, Appendix A. County records indicate the land is owned by USA Boulder City NV. The building is listed by BOR’s MSO under Building ID No. 0045000100B.

2.2 Physical Description

The three-story structure with a basement is rectangular-shaped and occupies a footprint of approximately 75 by 35 feet. A plan view is attached as Figure 2, Appendix A.

The building is constructed of masonry block walls with a stucco exterior. The foundation of the building is a concrete slab floor with poured concrete basement walls. The flooring of the structure is finished concrete slab on grade in the basement. The flooring on the first and second floors is poured concrete. The composition of the third floor is assumed to be composed of a wooden sheathing subfloor on top of wooden joists. Roofing is red vitreous tile over tarpaper or hot tar on wooden sheathing and wooden rafters. Finished ceilings are comprised of dropped ceilings with acoustic panels in hallways and office spaces in the basement, first and second floors. Ceilings in utility vaults and maintenance areas are painted concrete. The third floor ceilings are a combination of dropped ceilings with acoustic panels and wood finished rafters.

2.3 Site History

According to BOR records, the structure was constructed in 1932. Renovations for which records were kept occurred in the 1940’s and 1994. During the 1940’s renovations, the second stories of the wings were added. Major renovation work was completed in 1994. These renovations included building rehabilitation, addition of handicapped access features, improved fire escapes, the underground communications center was added as well as an additional underground exit for safety reasons. Also in 1994, the garage area on the west end was converted to offices.

2.3.1 Building Use

Historically, the building has been used for office space. Currently, the structure houses the regional administration offices. According to BOR’s MSO, the anticipated future use of this property is consistent with its past use.

December 14, 2007 Boulder City, Nevada

2.3.2 Building Inspection

The building was visually inspected by BOR and Zenitech staff on October 29, 2007. During this inspection, suspect building components and surfaces were identified and recorded on a Building Materials Assessment Summary Sheet. The summary sheet is provided in Appendix B of this report. Representative samples were collected of suspect building materials and noted on a field sampling record.

Sampling is discussed in further detail in Section 3 of this report.

Page 5 Building Condition Assessment

December 14, 2007 Boulder City, Nevada

Section 3 Sampling and Analysis

3.1 Sampling Design

Sampling design was based on four fundamentals. These include:

1. Preplanning of sampling through a physical site inspection

2. Use of approved and recommended sampling methods

3. Professional judgment exercised by the sampling personnel

4. Application of data quality objectives (DQOs)

The building was first visually inspected by BOR and Zenitech staff on October 29, 2007. During this inspection, suspect building components and surfaces were identified and recorded on a Building Materials Assessment Summary Sheet. The summary sheet is provided in Appendix B of this report.

Sampling methods used were based on EPA and OSHA/NIOSH recommended practices, where such methods exist, and upon sound scientific practices.

Methods adopted by Zenitech are described in the Standard Operating Procedures (SOPs). The SOPs for sampling asbestos, lead based paint and their associated decontamination methods are provided in Appendix D.

Professional judgment is utilized in deciding sample location and frequency. It is typical in a commercial structure to conduct representative sampling. The sampler examines the construction materials, the surface treatment, coatings, and more recent additions such as adhesives, mastics, or painted trim. Sample locations are selected to best represent each of the apparent materials, such that if all four walls of a room appear to be identically constructed and coated, fewer than four walls may be sampled. Likewise, when construction materials or coatings appear to be different, additional samples are typically collected.

Finally, DQOs are applied to the data collection and interpretation process.

DQOs are steps taken to ensure that the data collected is of sufficient quality and quantity to support the required decision. In the case of a BCA for hazardous substances, the qualified data is intended to identify whether remodeling, renovation, or demolition will require special procedures due to the presence of sufficient quantities of a hazardous substance.

3.2 Sample Collection

Samples of suspect ACM and LBPs were collected on November 5-6, 2007 by Zenitech personnel. A total of 19 ACM samples were collected from the interior of the building. Representative materials sampled include duct mastic, insulation, wall components, and ceiling tiles. A total of 19 lead samples were collected from

Page 6 Building Condition Assessment

December 14, 2007 Boulder City, Nevada the exterior and the interior of the building. Exterior surfaces sampled include walls, doors, railings and grout, window frames, and pipes. Interior representative samples include paint from rafters and other stained wood, window frames, walls, doors, railings, and floors. Based on the site inspection, it was not deemed necessary to sample for the presence of other heavy metals or for PCBs..

3.2.1 Sample Recordation

Each sample was issued a sample ID, then collected, containerized, and logged onto a Building Composition Field Sampling Record. These sampling records are provided in Appendix B. The reader is advised that some field sampling records may list samples from other buildings. This report applies only to the specific building described in this report.

Sample locations are depicted on a floor plan (Figure 2, Appendix A), in addition to being described on the field sampling record. All samples are also shown in summary tables in Appendix A.

3.2.2 Sampling Methods

Sampling methods adhered to Zenitech SOPs (Appendix D), unless otherwise noted in the sample description of the field sampling record.

ACM sampling was performed according to the Zenitech SOP for sampling of bulk materials, which is based on EPA methodology specified under Subpart E of AHERA, 40 CFR § 763. ACM sampling was conducted by a Nevada-licensed, EPA-certified asbestos inspector (Mr. Eric Wang).

LBP samples were collected according to the Zenitech SOPs for paint chip sampling by area or bulk, which are based on the EPA/HUD guidelines of Title X, 40 CFR § 745. LBP sampling was conducted by lead inspectors trained according to EPA’s 24-hour course requirements (Messrs. Christopher Adcock and Matt Stinchfield, and Ms. Becki Dano).

3.2.3 Sample Handling

After collection and logging, samples were recorded onto a Chain of Custody (COC) document. All samples were maintained under custody of Zenitech from the time of collection until shipment to the laboratory. No sample preservation, such as refrigeration or acidification, was required of this set of samples. COCs are provided after the laboratory analysis in Appendix C.

3.2.4 Decontamination

Decontamination of sampling equipment was performed according to the Zenitech SOP. Disposable sampling and decontamination articles were used once and then disposed of as solid waste.

Page 7 Building Condition Assessment

December 14, 2007 Boulder City, Nevada

3.2.5 Sampling QA/QC

Two blind quality control (QC) samples were submitted to the laboratory during this series of building assessments. Although the QC samples may not have been collected from the building in question, the results nevertheless demonstrate that sampling and laboratory procedures were in control. The results of these QC samples are discussed in Section 3.3.4.

3.3 Laboratory Analysis

3.3.1 Laboratory Selection

ACM and LBP samples were analyzed by Forensic Analytical (Hayward, California).

The laboratory was selected on the basis of the following criteria:

1. Licensure

2. Past performance

3. Price reasonableness

4. Turnaround time of results

5. Quality assurance program and proficiency test results

Forensic Analytical. Forensic is accredited for bulk asbestos analysis by polarized light microscopy by the National Voluntary Laboratory Accreditation Program (NVLAP). The lab is accredited for lead analysis by the Environmental Lead Laboratory Accreditation Program (ELLAP) sponsored by the American Industrial Hygiene Association (AIHA). The State of Nevada does not currently require a state license for the analysis of ACM or LBP in bulk samples.

The past performance of Forensic, based on two years of steady use by Zenitech, has been exceptional. The laboratory report forms are clear. Multilayered samples are reported as individual layers and as a composite whole. Forensic’s pricing is consistent with other laboratories in the industry. Analysis turnaround time has not been exceeded. Proficiency testing is discussed in Section 3.3.4, below.

3.3.2 Method Selection

Analytical methods chosen for this work are proven and reliable methods required by applicable regulations, agency guidance documents, and sound scientific practice. ACM bulk samples were analyzed by EPA Method 600 (comparable to ELAP 198.1). LBP chip and bulk samples were analyzed according to EPA Methods 3050 (extraction) and 7420 (lead by atomic absorption).

Page 8 Building Condition Assessment

December 14, 2007 Boulder City, Nevada

3.3.3 Analytical Results

Asbestos Results. A total of 19 bulk ACM samples were obtained of suspect building materials from the interior of the Administration Building. Bulk asbestos analysis provides the following: percent asbestos content, asbestos mineral, and quantification of other fibrous materials identified in the sample. 2 samples of wall adhesive from the first floor showed asbestos content of 2%. These samples were located in the A-111 Maintenance Area. In their current condition these materials are not friable although OSHA considers the possibility that these materials could become friable during remodeling, renovation, or demolition.

These materials are classified as Category I non-friable RACM. The remaining 17 samples showed no detectable asbestos. The sample source, sample description, and total asbestos percentage are provided in Table 1, Appendix A. Reported laboratory results are included in Appendix C.

Lead Results. A total of 19 chip and bulk samples were collected from the interior and exterior of the Administration Building. The laboratory reported final adjusted values of total lead for chip samples in units of mg/cm2, based on the sample area provided by Zenitech. Bulk samples were reported in mg/kg. Exterior surfaces sampled include walls, doors, railings and grout, window frames, and pipes. Interior representative samples include paint from rafters and other stained wood, window frames, walls, doors, railings, and floors.

Two of the 17 paint chip samples exceeded the EPA/HUD limit of 1.0 mg/cm2:

29 mg/cm2 on the exterior painted stucco (sample BCS-AB-EXTS-01) and 11 mg/cm2 on an interior window frame on the third floor (sample BCS-AB-INTW- 01). Of 17 area paint chip samples, 78 percent of all samples fell within one order of magnitude of the detection limit, with a detection limit averaging 0.002 ± 0.001 mg/cm2 (95% confidence).

Of the 2 bulk samples, 1 exhibited detectable lead but not in excess of the EPA/HUD limit of 5,000 mg/kg. A sample from the stained wood on the third floor ceiling was reported at 2,900 mg/kg total lead (BCS-AB-INTS-09). Sample descriptions and lead results are provided in the Table 2, Appendix A. Reported laboratory results are included in Appendix C.

3.3.4 Quality Assurance / Quality Control (QA/QC)

Field-Based QC Samples. A blind field blank (BFB) was submitted for bulk asbestos analysis (sample ID BCS-TP-Exterior-7). This sample was comprised of a post-1978 produced material (cellulose covered fiberglass pipe wrap), which is known to not contain asbestos. The purpose of this sample is to demonstrate that the laboratory can correctly identify material that does not contain asbestos. The reported result for all layers of the material was “none detected.”

A blind field duplicate (BFD) pair was submitted for total lead analysis (sample ID BCS-BB-EXTS-02 and BCS-BB-EXTS-03). These samples were collected from

Page 9 Building Condition Assessment

December 14, 2007 Boulder City, Nevada the same surface, close to one another, and were submitted as two distinct samples to the laboratory. The closeness of results in a BFD pair indicates that the substance sampled is reasonably homogeneous and that the sampling technique is reproducible. The results from this pair were 0.015 mg/cm2 and

0.022 mg/cm2, respectively, with a relative percent difference (RPD) of 38%.

These results demonstrate reasonable closeness, but are suggestive of heterogeneity in the thickness of the paint.

Laboratory Quality Assurance. Forensic participates in its own QA program, as well as proficiency testing programs for its various analytical specialties. The most recent results of proficiency testing under the Environmental Lead Proficiency Analytical Testing (ELPAT), the Industrial Hygiene Proficiency Analytical Testing (IHPAT), and the NVLAP proficiency testing programs are provided after the COC documents in Appendix C.

In addition to proficiency testing, Forensic also performs regular QC with each analytical batch. For asbestos, QC includes duplicate fiber counts. For lead, QC includes method blanks (MB) and laboratory control standards/laboratory control standard duplicates (LCS/LCSD). For this BCA, copies of laboratory QC reports were not requested.

Section 4 Conclusions and Recommendations

4.1 Conclusions

Samples collected of suspect ACM revealed regulated asbestos containing materials in excess of 1 percent asbestos in a wall component adhesive on the first floor in the Administration Building. This material is subject to AHERA during renovation, remodeling, or demolition activities that may involve cutting, grinding, or mechanical chipping of the wall components.

LBPs were found to be in excess of regulatory or guidance levels in interior and exterior painted surfaces including interior window frames and exterior painted stucco. In the event that remodeling, renovation, or demolition of this structure is necessary, OSHA-specified management practices will be required of the owner and contractors prior to and during remodeling, renovation, or demolition. Specific findings and recommended practices are described below.

4.1.1 Regulated Asbestos Containing Material

Regulated asbestos containing material (RACM) is an asbestos containing composition that exhibits greater than one percent asbestos content and is either friable or may become friable (Category I and II) during removal. Friable, when used to describe RACM, means that the material may emit airborne asbestos fibers using hand pressure, or that the material is already broken into sub-4-inch sized pieces. The Administration Building was found to contain Category I non-friable RACM in the wall adhesive of the first floor A-111 Maintenance Area. This RACM is considered non-friable in its current state but may become friable during remodeling, renovation, or demolition activities.

4.1.2 Lead Based Paint

OSHA’s means of regulating lead exposure is different from that of asbestos.

With lead, any amount of lead used in the construction materials that could release quantities of lead sufficient to exceed the permissible exposure limit (PEL) triggers compliance with the Lead in Construction standard. It is up to the building owner and contractors to measure airborne lead levels during remodeling, renovation, or demolition. In a child occupied facility, such as a home or school, EPA has established a definition for leaded paint that is any surface greater than

1.0 mg/cm2 or 5,000 mg/kg in a bulk sample.

In the Administration Building lead content exceeding the EPA limit for a child occupied facility was detected in painted exterior stucco and interior window frame surfaces. Based on these findings, compliance with the OSHA standard is recommended during remodeling, renovation, or demolition of the building.

4.2 Recommendations Pertaining to Remodeling, Renovating, or

Demolition of the Structure

In the event that the Administration building is to undergo partial or complete remodeling, renovation, or demolition involving any of the previously noted surfaces, Zenitech recommends specific management procedures to comply with existing regulations and to maintain a safe and healthy work environment. It is possible, though unlikely, that hazardous building materials may have been added to the structure between the time of this inspection and future site activities. Such hazardous substances could arise from retrofitting with used materials, use of non-approved paints originating from a foreign supplier, or from industrial activities involving the use of hazardous substances.

4.2.1 Asbestos Management

Notification and Permitting. RACM is present in the components described in Section 4.1, above. Proper removal of RACM prior to renovation or demolition is required by the National Emissions Standards for Hazardous Air Pollutants (NESHAPs) under the Clean Air Act (CAA). Notifications of abatement activity must be provided to both the CAA and OSHA delegated authorities.

NESHAP authority in Boulder City is administered by the Clark County Division of Air Quality and Environmental Management (DAQEM). DAQEM requires the submittal of a Notification of Asbestos Abatement form and payment of a fee prior to asbestos abatement work that equals or exceeds any of the following quantities: 1) 260 linear feet of piping, 2) 160 square feet, or 3) 35 cubic feet of RACM. Quantities below these thresholds require a courtesy notification without a fee.

The authority of the Occupational Safety and Health Administration (OSHA) is granted to the Nevada Division of Industrial Relations (NDIR). NDIR requires the submittal of an Asbestos Abatement Project Notification Form prior to beginning abatement activities. Fees are based on the quantities of RACM being managed and are different from the thresholds stipulated in NESHAPS. Demolition in Clark County may also require other DAQEM permits and notification of the local fire department.

Selection of Contractors. In Nevada, asbestos abatement contractors must carry two state licenses. A class A23 license from the Nevada State Contractors Board (NSCB) is required for the company. Contractor names can be checked against the NSCB database to determine current status. Abatement contractors are also required to be licensed by NDIR by providing proof of their NSCB license, completing the ACP-1 form, providing evidence of training, and submitting a registration fee.

Contractor Requirements. A licensed abatement contractor shall provide a workforce of trained and Nevada-certified asbestos workers. The contractor will

Page 12 Building Condition Assessment

December 14, 2007 Boulder City, Nevada adhere to work zone requirements and control airborne asbestos levels in compliance with the OSHA asbestos standard (29 CFR § 1910.1001). Workers will be provided with respirators, other personal protective equipment, engineering controls (such as HEPA filtering blowers and glovebags), and decontamination facilities. The contractor shall place workplace signs and site controls to isolate the asbestos work area in accordance with AHERA requirements.

Assignment of a Third Party Inspector. Zenitech recommends that BOR separately retain a Nevada licensed asbestos consultant. The consultant must be licensed by the NDIR. The consultant will review abatement and demolition plans, conduct monitoring during and after abatement, provide visual inspection and sampling of newly discovered materials, assure that contractor signage and engineering controls conform to OSHA requirements, and review all contractor deliverables related to the abatement work.

Documented Waste Management. RACM created and disposed of within Nevada is considered a “special waste” and requires specific packaging, labeling, and disposal practices. Asbestos waste resulting from abatement activities must be secured at all times to avoid exposure to unqualified persons. Waste transportation and disposal records must be maintained by BOR.

4.2.2 Lead Management

Notification and Permitting. At this time, there are no pre-work notifications required prior to lead abatement. The driving principal behind compliance during lead paint abatement is to provide a safe and healthful workplace for workers under the OSHA Lead in Construction standard (29 CFR § 1926.62).

It is a general practice in the industry, that where abatement of both RACM and LBP is required, the asbestos abatement precedes the lead abatement.

Selection of Contractors. In Nevada, lead abatement contractors must carry a class A22 license with a lead abatement endorsement from the NSCB.

Contractor names can be checked against the NSCB database to determine current status.

Contractor Requirements. A licensed abatement contractor shall provide a workforce of trained lead abatement workers. Workers will be provided with respirators, other personal protective equipment, engineering controls (such as HEPA filtering blowers and paint removal tools), and decontamination facilities.

The contractor shall place workplace signs and site controls to isolate the lead work area in accordance with OSHA requirements.

Assignment of a Third Party Inspector. Zenitech recommends that BOR separately retain an EPA certified lead inspector. The inspector must have undergone EPA-approved training. The inspector will review abatement and

Page 13 Building Condition Assessment

December 14, 2007 Boulder City, Nevada demolition plans, conduct monitoring during and after abatement, provide visual inspection and sampling of newly discovered materials, assure that contractor signage and engineering controls conform to OSHA requirements, and review all contractor deliverables related to the abatement work.

Documented Waste Management. LBP debris must undergo a Resource Conservation and Recovery Act (RCRA) waste determination prior to disposal.

For each type of debris (e.g. block wall rubble, window frames, painted wood, etc.) a representative sample must be evaluated by the TCLP extraction method for lead. Debris which falls below 5.0 mg/l TCLP lead is considered a non-hazardous solid waste and may be placed directly in a permitted sanitary landfill or construction/demolition landfill. Under no circumstances can lead-containing debris be used as fill or be buried in the absence of a Nevada solid waste permit.

Debris which exceeds 5.0 mg/l lead must be managed as a hazardous waste.

Hazardous waste debris must conform to the Land Disposal Restrictions (LDRs) and be treated by a permitted operator to less than 0.75 mg/l TCLP lead prior to placement in a land disposal unit. If the physical address of the building does not have a previously assigned EPA generator ID number, one must be obtained by BOR prior to waste generation and shipment.

Transportation and disposal records must be maintained by BOR for all forms of lead waste generated and managed.

4.2.3 PCBs and Fluorescent Light Fixtures

During site inspection and sampling activities, not all fluorescent light fixtures were viewed. It is possible that PCB-containing fluorescent light ballasts do exist in the subject building, and that during remodeling, renovation, or demolition, these may require specific handling and disposal practices. In general, light ballasts manufactured after 1979 without PCBs will have the “No PCBs” designation printed on the ballast. Ballasts without this designation are considered to have PCBs. Non-leaking PCB ballasts meet the definitions “PCB electrical equipment” and “small capacitors” and may be disposed of into a permitted hazardous waste landfill. Leaking PCB ballasts are considered “leaking PCB electrical equipment” pursuant to 40 CFR § 761.3 and should be incinerated at a RCRA permitted hazardous waste incinerator.

Fluorescent light bulbs, both the long tubes and the newer coil types, are known to contain mercury. Bulbs that have reached the end of their service life should be sent to a licensed mercury bulb recycler.

4.3 Limitations of Inspection

Building materials that were not apparent (such as wrapped, buried piping) or not accessible without destructive force (such as roofing felt under ceramic tile roofs) were not physically inspected or sampled during this BCA. Such building
