1. INTRODUCTION <br />The Citv of Santa Ana retained Lead Tech Environmental (LTE) to perform an asbestos <br />survey of a single family residence located at 714 E. 6u' Street, Santa Ana, California, <br />( "Residence "). <br />The asbestos survey was performed by Michael Kuretich, a certified site surveillance <br />technician (CAL OSHA 02 -3261) under the guidance of Joseph Somoye, a California <br />OSHA Certified Asbestos Consultant on June 4, 2009, <br />2. LIMITED AREAS SAMPLED FOR ASBESTOS <br />LTE performed an asbestos survey of Suspect Asbestos Containing Materials (ACM) <br />throughout the Residence by sampling the interior plaster and sheet rock walls, acoustic <br />ceilings, vinyl flooring, roof shingle, roof penetration mastic and window putty. In total, <br />LTE took thirty (30) samples. <br />3. SAMPLING PROTOCOL <br />LTE sampled the materials that will be disturbed during rehabilitation pursuant to the <br />Environmental Protection Agency (EPA) 40 CFR Ch. I Section 763.86 page 654. As <br />recommended by EPA Guidance document 700B- 92/001, LTE took at least 3 samples <br />from each homogenous area that is 1,000 sq /ft2 or less; 5 samples from each homogenous <br />area that is greater than 1,000 sq /ft2 but less than 5,000 sq /ft2; and 7 samples from each <br />homogenous area that is greater than 5,000 sq /ft2. <br />For non friable suspect ACM, LTE took 3 samples of each homogenous material. <br />4. ANALYTICAL METHOD <br />Upon completion of the asbestos survey, our inspector completed chain -of- custody forms <br />and sent same with bulk samples to the laboratory for bulk sampling analysis. Asbestos <br />samples were sent to Advanced American Laboratory for bulk sample analysis ( "AAL" ). <br />It is accredited by the National Institute of Standards and Technology (NIST) under the <br />National Voluntary Laboratory Accreditation Program (NVLAP) for analysis. <br />Bulk sample analysis was performed using Polarized Light Microscopy with Dispersion <br />Staining (PLM/DS) in accordance with the Environmental Protection Agency's (EPA) <br />"Interim Method of Determination of Asbestos in Bulk Insulation Samples ", EPA <br />Method 600/M4 -82 -020 and EPA Method 600/R- 93/116. The identification of asbestos <br />fiber bundles is determined by the visual properties displayed when the sample is treated <br />with various dispersion staining liquids. Identification is substantiated by the actual <br />structure of the fiber and the effect of polarized light on the fiber, all of which is viewed <br />by the trained laboratory technician. <br />5. DEFINITION OF ASBESTOS <br />The EPA's Asbestos National Emissions Standards for Hazardous Air Pollutants <br />(NESHAP) and the South Coast Air Quality Management District (SCAQMD), the local <br />air pollution control district, define an asbestos - containing material as any material that <br />contains a concentration of asbestos of greater than one percent ( >1.0 %,) by area as <br />determined by PLM (40 CFR Part 763, Appendix A, Subpart F Section 1). <br />190 -49 <br />
