(SEI) provided air monitoring services for Eco Tech Environmental Inc. (ETE) at the Timber Ridge Apartments, Building N, Unit #3, 1280 North Frontage Road West, Vail, Colorado 81657 on July 18, 2014. The field representative for SEI was Mr. Scott D. Sanders. Work was performed in conjunction with asbestos abatement at the site. Asbestos abatement was conducted by ETE; a Colorado Department of Public Health & Environment (CDPHE) licensed General Abatement Contractor (GAC). SEI’s scope of work included collection and analysis of final clearance air samples, performing a visual inspection of the work area prior to collection of air samples, and assembling project documentation. Subsequent to cleanup, SEI visually inspected the containment areas for visible dust and debris. Upon passage of visual inspection, SEI collected final clearance air samples and notified ETE when laboratory results indicated airborne fiber concentrations were not in excess of 0.01f/cc as required by CDPHE Regulation No. 8. At project completion, air-monitoring results indicate concentrations of airborne fibers were not in excess of 0.01f/cc as required by the Environmental Protection Agency (EPA) and CDPHE for re-occupancy following asbestos abatement. CLIENT: Eco Tech Environmental Inc. 2331 West Hampden Avenue Suite 137 Sheridan, Colorado 80110 PROJECT LOCATION: Timber Ridge Apartments 1280 North Frontage Road West Vail, Colorado 81657 Building N, Unit #3 DESCRIPTION OF WORK: Final Visual Inspection & Final Clearance Air Monitoring ASBESTOS ABATEMENT CONTRACTORS: Eco Tech Environmental Inc. SUNRISE ENVIRONMENTAL INC. REPRESENTATIVE: Mr. Scott D. Sanders INTRODUCTION SEI provided air monitoring services for ETE at the Timber Ridge Apartments, Building N, Unit #3, 1280 North Frontage Road West, Vail, Colorado 81657 on July 18, 2014. The field representative for SEI was Mr. Scott D. Sanders. Work was performed in conjunction with the removal of asbestos containing building materials at the site. Asbestos abatement was conducted by ETE; a Colorado Department of Public Health and Environment (CDPHE) licensed General Abatement Contractor (GAC). SEI performed the final visual inspection, and the collection and analysis of Phase Contrast Microscopy (PCM) air samples after asbestos abatement. SEI successfully participates in the AIHA Proficiency Analytical Testing (PAT) Program (Laboratory ID# 196102). All SEI analysts have been certified in NIOSH 582E to perform collection and analysis of PCM air samples. SCOPE OF WORK ETE’s scope of work for this project consisted of the removal/disposal of: 1. Approximately 150 square feet of sheet vinyl flooring was removed from the kitchen, dining area, and entryway. SEI has performed the following Industrial Hygiene services: • Performed a visual inspection of the abatement areas, • Collection and analysis of PCM air samples to monitor concentrations of airborne fibers after asbestos abatement in accordance with CDPHE Regulation No. 8, • Assembled and submitted project documentation. The findings set forth in this report are strictly limited in time and scope to the date of the evaluation. The conclusions presented in the Report are based solely on the services described therein, and not on scientific tasks or procedures beyond the scope of agreed upon services. SEI was not responsible for determining which asbestos-containing materials were to be included in the abatement scope of work. PROJECT DESCRIPTION Sequence of field work: Table 1 summarizes the field work in the order in which it was completed. Table 1. Summary of Field Work DATE FIELD WORK 07-18-14 Pre-clearance visual inspection of the containment is performed. (ETE, SEI) Collection of five (5) PCM final clearance air samples inside the containment. (SEI) All PCM clearance samples are below 0.01f/cc. ETE on-site supervisor is notified. (SEI) AIR MONITORING Sample Collection The effective filter area for samples collected on July 18, 2014 was 385mm2. PCM samples were collected on 25 millimeter (mm) mixed cellulose ester membrane filters (0.8 micron pore size). The filters were preassembled by the manufacturer. Air samples were collected at a flow rate of 15.6 to 15.7 liters per minute (LPM). Flow rates were recorded at the beginning and at the end of the sampling period using a DryCal™ Primary Standard flow calibrator. All air samples were collected open-faced and positioned at breathing zone height (approximately five feet above the floor) with exposed portion of the cassette facing downward. Clearance air samples were collected aggressively and in accordance with CDPHE Regulation #8. (See Appendix A for sample data) PCM Analysis Methodology PCM samples were analyzed by SEI according to the NIOSH 7400 Method (“A” counting rules). This method can be found in the NIOSH Manual of Analytical Methods. All air sample results are calculated with blank corrections, checked and reviewed. Unused portions of samples are archived three months unless client requests special handling. Laboratory analysis was accomplished utilizing a Phase Contrast Microscope. Size and fiber counts were performed at 400X magnification. The microscopy field area (MFA), defined by the Walton-Beckett Graticule is 0.00785mm2. Report Data Key Fbrs/Flds: Fibers per fields; total fibers counted over total areas examined. LOD: Limit of Detection; the calculated lower limit of detection expressed in fibers per cubic centimeter. Based on limit of detection of (5.5/100 fibers/field). F/cc: Fibers per cubic centimeter. ≤ LOD: Less than or equal to the limit of Detection; thus, the analytical result is less than or equal to the value indicated in the LOD column. CONCLUSIONS At project completion, air-monitoring data indicate concentrations of airborne fibers were not in excess of 0.01f/cc as required by the Environmental Protection Agency (EPA) and CDPHE for re-occupancy following asbestos abatement.
