1.0 INTRODUCTION

An environmental survey for Asbestos Containing Materials &Lead Based Paint (LBP) Components was conducted by a Puerto Rico Environmental Quality Board certified Asbestos & Lead Inspector. The survey was conducted on November 30, 2018 for the PR-128, Km. 9.0, Km 15.2, Km 17.30 & Km. 17.35, AC Project 823544/ER9999(332), Yauco, Puerto Rico. Refer to Appendix A for Aerial Photo.

For Lead, the survey was conducted using a XRF instrument and using Department of Housing and Urban Development (HUD) protocol. The hazard level for lead in paint is 1.0 mg/cm², as measured by XRF.

For Asbestos, the survey was performed based on AHERA protocol, according the following scenario:

A. The structure was divided in functional spaces.

B. Physical and Hazard Assessment of suspected asbestos containing materials was performed.

Asbestos was used in the construction industry from 1900 to 1989 and still being today in various products. The mere presence of asbestos containing materials does not necessary constitute a health hazard. However, when these materials become disturbed from building renovation, maintenance, or other activities that allow asbestos fibers to be released into the environment, a potential hazard does exist.

2.0 TESTING / SAMPLING PROCEDURES

The main steps involved in lead based paint inspection are:

A. Perform inventory of all testing combinations.

B. Select painted area to be tested.

C. Perform the XRF testing including the calibration.

D. Evaluate and classify the data.

The identification of tested walls is based on HUD guidelines as follow, where the structure has rooms or functional spaces:

A. Wall A - entrance Wall

B. Walls B, C and D - sequential walls, clockwise from A.

C. For Roads or Highways the testing are selected in the painted areas and this type of projects is not part of HUD guidelines.

For asbestos, all functional spaces were visited and visually inspected to identify the location of any suspected ACM. An assessment was made of the friability of suspected ACM by touching the material to determine if could be pulverized, crumbled or reduced to power by hand pressure.

3.0 INSPECTION RESULTS FOR LEAD BASED PAINT

A total of three (3) selected areas were tested for lead. All of these testing were found under the regulatory limit of 1.0 mg/cm² for Lead. The project areas in Road PR-128, Km. 9.0 to Km. 17.35, AC Project 823544, Yauco, Puerto Rico is lead based paint free. See the Appendix B for lead based paint sampling results tables. See the Appendix C for the Negative Certification.

4.0 INSPECTION RESULTS FOR ASBESTOS

The samples are defined as asbestos containing materials (ACM) if they contain more than 1% of asbestos. Samples are analyzed by Polarized Light Microscopy method (PLM), in accordance to EPA recommended procedures. Any bulk sample was collected for PR-128 AC Project 823544, because no suspicious material for asbestos was found.

The PR-128, Km. 9.0 to Km. 17.35, AC Project 823544 is asbestos free. See the Appendix D for the Negative Certification.

CONCLUSIONS

For Road PR-128, Km. 9.0, Km 15.2, Km 17.30 & Km. 17.35, AC Project 823544, the works areas are asbestos and lead free. However the contractor should be comply, with the general’s permits before the renovation / demolition activities, following the local and federal regulation.
