The asbestos abatement was being conducted to remove —177 sf of asbestos-containing drywall surfacing texture and associated joint-compound from the upper level bathroom walls and ceiling and^'130 sf of asbestos- containing grout from the upper level bathroom floor. The abatement project passed the final visual inspection and the analytical results of all final clearance samples collected were below the CDPHE's clearance criteria of 0.01 fibers/cubic centimeter (f/cc). The containment area can be deconstructed, and the abatement area can be re-occupied. 2.0 Project Details GAC&Permit General Abatement Contractor(GAC) Colorado Hazard Control (CHC) GAC Supervisor Roy Janway CDPHE Permit Number - I Containment Details Number of Containments 1 f 1 , Containment Type(s) Full Coniainmeni Containment Area(s) Upper Level Bathroom Analyzation Details Sample Analyzation Method Phase Contrast Microscopy(PCM) Analyzation Method NIOSH 7400 Number of Samples Collected 5 Number of Blank Samples Collected 2 Asbestos-Containing Materials Abated Tine n{A/-AA I (14nn tit,,Dem na,nrl I Location Rem roma From Drywall Surfacing Texture&Associated —177 sf Upper Level Master Bathroom Walls and Ceiling Joint Compound Grout ^'130 sf I Upper Level Bathroom Floor 3 3.0 Certifications The final visual inspection, the aggressive clearance air monitoring, and the PCM air sample analyzation were conducted by Mr.Zack Westfaii with DS.Mr. Westfall is a CDPHE certified Air Monitoring Specialist(AMS);having certification number 22529 and a NIOSH 582 certified analyst. DS is a CDPHE certified Asbestos Consulting Firm, Registration No. 14912 and a participant in the Industrial Hygiene Proficiency Analytical Testing(IHPAT)program with lahnratnry Ill No 1 RRciR7 maintaining a rating of Prnfiriant 4.0 Final Visual & Final Clearance Procedures Prior to the collection of final clearance air samples, a final visual inspection was conducted to ensure all the requirements of CDPHE's Regulation 8, Part B—Asbestos were met. Once the abatement area passed the final visual inspection, DS collected final clearance air samples from five (5) locations within the containment. Following the collection of the final clearance air samples,the samples were analyzed, along with sample blanks, to determine the airborne fiber concentrations. The air samples were collected at an average flow rate of less than 16.0 liters per minute (L/m) using Thomas high-volume pumps with a minimum volume of air to meet the analytical sensitivity for the NIOSH 7400 analyzation method used to analyze the samples. Flow rates were collected at the beginning and at the end of the sampling period utilizing an airflow rotameter calibrated against a primary-flow calibration instrument.Start times and stop times were recorded for ail sampling periods. 5.0 Air Sample Analyzation The final clearance PCM samples were collected on 25-millimeter(mm)mixed-cellulose, ester-membrane filters with a 0.8-micron pore size and an effective collection area of 385 mm. All filters were pre-assembled by the manufacturer in three-stage, conductive sampling cassettes with extension cowls. A field blank and lab blank were also collected and analyzed along with the clearance samples. The final clearance PCM samples were analyzed according to the NIOSH 7400 Method. This method counts and identifies "fibers" that meet the counting criteria for the method. which is not specific to asbestos fibers: therefore, all fibers that meet the counting criteria are counted as asbestos fibers. If the total fiber count is less than 0.01 fibers/cubic centimeter (f/cc), it is known that the total asbestos fiber count is also less than 0.01 fibers/cubic centimeter (f/cc). 4 6.0 Air Sample Results IClearance' Sample I Avg Flow I Time I Volume I Fibers/ I Reporting I Results!
