d Asbestos Assessment Reports Proposal for Various Environmental Services Page 23 August 1, 2022 Upon receipt of analytical results from the laboratory, A -Tech will prepare an asbestos assessment report that summarizes pre -field activities, field visual inspections, field sampling activities, sampling results, and recommendations. Our asbestos assessment reports will include (but not be limited to) the name of the surveyor, CACs and project manager; methods and procedures that were utilized in sampling and analysis; the date of survey; drawings and photographs of sampling locations; the laboratory qualifications statement; the existing conditions of the facility; a description of any identified ACM; and recommendations regarding asbestos handling and disposal, if needed. If ACM was identified at the project site, an asbestos abatement work plan will also be prepared and submitted along with the asbestos assessment report that will clearly identify procedures and steps to be followed by the abatement contractors. After internal review and quality control, the draft reports will be reviewed by a professional editor and the editor's comments will be reviewed and incorporated, as appropriate. Asbestos Field Monitoring When a project requires abatement, per regulations the City is required to directly hire an abatement contractor to perform the abatement activities. Once the abatement work plan is finalized, A-Tech's Lead and CACs will assist the City's project manager with bid package development and review of the submitted bids. A -Tech is experienced in coordinating, monitoring, and clearing abatement projects to make sure our clients can gain access to work areas in a timely manner. A -Tech will coordinate with the City on each project to ensure all project documentation meets all regulatory requirements. We will make sure that all required oversight agencies' notifications and documents are submitted by the abatement contractor on time to avoid project delays. During abatement activities, our experienced field technicians will provide oversight of abatement contractors' activities and conduct personal and ambient air monitoring for the work area, as necessary. We will work with the City to maintain the project schedule and can coordinate either with the necessary personnel to schedule clearance tests that will streamline the finalization of the project without lag time. Our approach allows our client as much or as little involvement as they are comfortable with. Asbestos Clearance (Close -Out) Report When the asbestos abatement has been completed, a final visual clearance inspection is conducted followed by air sampling that is analyzed on -site by Phase Contrast Microscopy (PC* utilizing a laboratory grade microscope, or off -site by Transmission Electron Microscopy (TEM) analysis, as necessary. For asbestos projects, we collect background, ambient and general air samples for on -site PCM analysis. If there is an elevated fiber concentration, we want to know right away to immediately modify engineering controls. When the entire abatement and remediation process is complete, a final close-out document will be prepared upon receipt of analytical results. The report will be delivered via email and/or standard mail based upon the City's preference. The final close-out document contains, at a minimum, an executive summary indicating methods of work; areas and materials abated; regulatory compliance; sample analysis findings and conclusions. The close-out report would also include (but not be limited to) project diaries, project checklists, permits, air monitoring logs, contractors' certifications, submittals and/or notifications, digital photographs, final visual inspection forms and clearance letters. 0 A -Tech Consulting, Inc.
