Union Drive Aurora, Colorado 80015 Report Prepared: May 24, 2010 SEI Project Number: SEI10-P049 Prepared By: Sunrise Environmental, Inc. 371 Crest View Drive Black Hawk, Colorado 80422 Phone: 720-209-5282 www.sunrise-enviro.com EXECUTIVE SUMMARY Sunrise Environmental, Inc. (SEI) provided air monitoring services for Reliance Environmental Services, LLC (RES) at The Landmark Unit 701, located at 610 Lionshead Circle, Vail, Colorado on May 23, 2010. 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 Reliance Environmental Services, LLC; a Colorado Department of Health licensed asbestos abatement contractor. SEI’s scope of work included collection and analysis of final clearance air samples, performing visual inspections of work areas 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 Reliance Environmental Services, LLC when laboratory results indicated airborne fiber concentrations were not in excess of 0.01f/cc as required by Colorado Department of Public Health and Environment (CDPHE), Regulation 8. At project completion, air-monitoring results indicate concentrations of airborne fibers did not exceed 0.01f/cc as required by the Environmental Protection Agency (EPA) and CDPHE for re- occupancy following asbestos abatement. CLIENT: Reliance Environmental Services, LLC. 20274 E. Union Drive Aurora, Colorado 80015 PROJECT LOCATION: The Landmark, Unit 701 610 Lionshead Circle Vail, Colorado DESCRIPTION OF WORK: Final Clearance Air Monitoring ASBESTOS ABATEMENT CONTRACTORS: Reliance Environmental Services, LLC. SUNRISE ENVIRONMENTAL INC. REPRESENTATIVE: Mr. Scott D. Sanders INTRODUCTION SEI provided air monitoring services for Reliance Environmental Services, LLC at The Landmark, Unit 701, located at 610 Lionshead Circle, Vail, Colorado on May 23, 2010. The field representative for SEI was Mr. Scott D. Sanders. Work was performed in conjunction with the removal of asbestos containing ceiling texture at the site. Asbestos abatement was conducted by Reliance Environmental Services, LLC; a Colorado Department of Public Health and Environment (CDPHE) licensed asbestos abatement contractor. 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) and participates in inter-laboratory and intra-laboratory round robin analysis. All SEI analysts have been certified in NIOSH 582E to perform collection and analysis of PCM air samples. SCOPE OF WORK Reliance Environmental Services, LLC’s scope of work for this project consisted of the removal/disposal of asbestos containing ceiling texture from Unit 701. SEI has performed the following Industrial Hygiene services: • Performed visual inspections 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 performed a visual inspection and collected final clearance air samples following the removal of accessible areas of asbestos containing ceiling texture in Unit 701. Suspect asbestos containing materials not included in the abatement scope of work may still be remaining in the unit, including but not limited to: asbestos containing drywall joint compound or drywall texture. 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 05-23-10 Pre-clearance visual inspection of Unit 701 containment. (RES, SEI) Collection and analysis of five (5) PCM final clearance air samples. (SEI) PCM clearance samples below 0.01f/cc. RES on-site supervisor is notified. (SEI) Containment is torn down. (RES) AIR MONITORING Sample Collection The effective filter area for samples collected on May 23, 2010 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 in conductive three stage cassettes with extension cowls. Air samples were collected at a flow rate of 14.8 to 15.0 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 the limit of Detection; thus, the analytical result is less than 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.
