SECTION 1: EXECUTIVE SUMMARY

1.1 INTRODUCTION

A Lead-Based Paint inspection was conducted on March 5, 2010 at the Tower IV located at Punta Salinas Radar Site in Toa Baja, PR. The lead-based paint inspection was performed to identify paint that contains lead above allowable levels that could result in harm to construction personnel, workers and especially to young children. This evaluation report can help Owners develop a plan for eliminating any lead-based paint hazards that were found, and may aid in establishing an ongoing lead-based paint maintenance and re-evaluation program, if needed.

1.2 SUMMARY OF PROPERTY EVALUATION

The project consisted of the evaluation on the interior and exterior areas of the Tower IV.

The evaluation found that lead-based paint was present in concrete surfaces, ceramic and metal component through the evaluated areas on the date of the inspection Table 1-1 identifies the components positive for lead.

1.3 SUMMARY OF LEAD-BASED PAINT

Table 2-1 identifies lead-based paint as defined by the U.S. Environmental Protection Agency (EPA) and the Environmental Quality Board (EQB). For specific locations and additional detail on the location of lead-based paint reference Sections 2 and 3.

1.4 PROPERTY LOCATIONS OF BUILDING COMPONENTS WITH LEADBASED

PAINT

Table 1-1 summarizes the side components coated with lead-based paint. Details that identify positive lead-based paint findings within specific areas and on surfaces were provided in the Lead-based paint inspection report. The “substrate” is the building component material directly beneath the painted surface.

If an abatement of the materials will be conducted the Contractors shall calculate their own quantification of the materials to be abated.

SECTION 2: LEAD-BASED PAINT INSPECTION REPORT

2.1 OVERVIEW OF THE EVALUATION

This lead-based paint inspection is an interior and exterior investigation to identify all leadbased paint on a surface-by-surface basis. A lead-based paint inspection conforming to HUD guidelines was performed at the structures.

Averages of 141 samples were taken at all identified surfaces on the inside and outside of the evaluated structure using X-ray fluorescence (XRF) analyzer. The evaluation found that leadbased paint was present in concrete surfaces ceramic & metal components through the evaluated structures on the date of the assessment (See Table 1-1) Some of the remaining XRF test locations exhibited lead-in-paint levels below the level that EPA identifies as lead-based paint, namely 1.0 mg/cm2. Such surfaces could create dust-lead or soil-lead hazards if the paint is turned into dust by abrasion, scraping, or sanding. Should these or any lead containing components or surfaces be disturbed in any manner that generates dust, care should be taken to limit its spread.

Testing was performed by Alfredo J. Pérez, state-certified inspector 8293-0409-LI-004, and Harry Peña, state-certified risk assessor 3357-1209-RA-0034, using the Niton XLp-300A XRF, SN-18574. The credentials are provided in Section 3, Appendix D: Certifications, Licenses, and Accreditations. The XRF analyzer is designed to measure the lead content of surface coatings on a variety of building surfaces, substrates, and components. The measurement is rapid and nondestructive and, according to the manufacturer, is capable of detecting lead concentrations that occur within numerous layers of various surface coatings.

Please refer to the XRF Testing Results Section 3, Appendix A: XRF Sampling Data for the detailed analytical testing results for each distinct area inspected. The reports provide a complete testing data.

2.2 SAMPLING PROCEDURE AND RESULTS PRESENTATION

The Lead Based Paint Sampling Procedure was design to evaluate and document all the data obtained form the inspection in a sequential method that provided confidence at the moment of the results presentation.

The survey was performed following the methodology established in the HUD Guidelines for the Evaluation and Control of Lead Based Paint in Housing (1997 revision) and the PREQB Lead Based Paint Abatement Control Regulation. The surfaces evaluation was performed as follows:

• If the lead concentration measured by the XRF Spectrum Analyzer is less than 1.0 mg/cm2 it is considered negative

• If the lead concentration measured by the XRF Spectrum Analyzer is equal or greater than 1.0 mg/cm2 it is considered positive. �

ZIMMETRY ENVIRONMENTAL MANAGEMENT CORP.

Lead Based Paint Inspection Punta Salinas Radar Site, Tower IV Toa Baja, PR To each functional space of the property a name was assigned according to the use of that space. If no name could be assigned then a code letter or number was assigned. The room numbers will be assigned clockwise as you enter the structure and go towards the left always.

Each wall surface was named with letters beginning with wall A the wall facing the main street or building main entrance. The wall at your left will be wall B, the wall at front wall C and the wall at you right will be wall D.

2.3 LEAD REGULATORY LEVELS

The lead regulatory levels provided below are those used when preparing this lead-based paint evaluation or when evaluating data collected. The EPA regulatory levels are the same as the state regulatory levels provided in the following table.

TABLE 2-1: LEAD REGULATORY LEVELS

EPA/EQB Levels Lead-Based Paint 1.0 mg/cm2 or 0.5% by weight (or 5,000 ppm) Lead in Dust Floor 40 µg/ft2 Window Sill 250 µg/ft2 Lead in Bare Soil Child-Play Areas (dwelling perimeter and yard) 400 ppm (µg/g) Rest of the Yard(dwelling perimeter and yard) 1200 ppm (µg/g)

2.4 CONDITIONS AND LIMITATIONS—DISCLAIMER

Zimmetry Environmental Management Corp. has performed this lead-based paint inspection in a thorough and professional manner consistent with commonly accepted industry standards. The Preparer cannot guarantee and does not warrant that this evaluation has identified all adverse environmental factors and/or conditions affecting this property on the date of the evaluation.

The results reported and conclusions reached by the Preparer are solely for the benefit of the Owner. The results and opinions in this report, based solely on the conditions found at the property on the date of the evaluation, are valid only on that date. The Preparer assumes no obligation to advise the client of any changes in any real or potential lead-based paint hazards at this residence beyond the date of the property evaluation.

The lead inspection was performed to ready accessible components and surfaces. If ceramic tiles or suspected components that could contain lead are encountered underneath current installed tiles or other construction material, they shall be managed as containing lead until the appropriate test is performed. Due to site conditions if possible that several areas could not be �

ZIMMETRY ENVIRONMENTAL MANAGEMENT CORP.

Lead Based Paint Inspection Punta Salinas Radar Site, Tower IV Toa Baja, PR evaluated. If suspected materials are identified they shall be managed as containing asbestos until the appropriated test is performed.

2.5 ABATEMENT CONDITIONS

Abatement, as defined by HUD and the Puerto Rico Environmental Quality Board (EQB), means any set of measures designed to eliminate lead-based paint and/or lead-based paint hazards permanently. The people providing these services must to be trained in accordance with the EQB licensing/certification requirements. The product manufacturer and/or contractor must warrant abatement methods to last a minimum of 20 years, or these methods must have a design life of at least 20 years.

Abatement activities may include, but are not necessarily limited to: the onsite or offsite removal of lead-based paint from substrates and components; the replacement of components or fixtures painted with lead-based paint; the permanent enclosure of lead-based paint with construction materials mechanically-fastened to the substrate; the encapsulation of leadbased paint with specially designed encapsulant products; or the removal or permanent covering (concrete or asphalt) of soil-lead-based paint hazards. If enclosure or encapsulation is conducted as an abatement method, the lead-based paint remains on the property, so ongoing lead-based paint maintenance is required.

2.6 RECOMMENDATIONS

According to the EQB lead regulations, prior to the demolishing of a structure containing lead based paint, the contaminated surfaces or substrates must be abated or removed. The waste generated has to be characterized to determine if the waste generated is hazardous or non hazardous waste. The firm providing the abatement services must be certified as an abatement firm by the EQB. Workers conducting abatement must be trained and certified as abatement workers by a training provider accredited by the EQB.

2.8 ENVIRONMENTAL ASSESSMENT REPORT CERTIFICATION
