Crawford,Murphy&Tilly <br /> ' William Street Pump Station,E.Main Street&S.29th Street, Decaur, IL <br /> October 6,2022/IDEAL Number 25115 <br /> ' Regardless of the classification of asbestos containing materials at the time of the inspection, if any non-friable material <br /> becomes friable during demolition or renovation,that material is then considered RACM and is subject to all NESHAP rules. <br /> ADDITIONAL SAMPLING/ANALYSIS OPTIONS <br /> y When sample analysis is stopped at the first positive, analysis of remaining samples is an option. <br /> y When friable and non-friable category II materials containing less than 10%asbestos as determined by PLM, EPA Method <br /> 600/R-93/116 were identified,they must be point counted`, analyzed by TEM or treated as assumed ACM prior to <br /> removal/renovation in commercial buildings or apartments with more than four units. TEM is recommended. ["PLM Point <br /> Count is a method specified in EPA regulations(NESHAP Final Rule). However, bulk sample analysis methods are <br /> continually improving, and other analysis methods are now available to help verify asbestos content. One of these methods <br /> is TEM, and EPA has subsequently specified that it is an acceptable alternative to PLM Point Count.] <br /> y If only one sample of a material has been collected, it is likely due to limited quantities or accessibility. If for any other <br /> reason and analysis indicates that no asbestos was detected, additional sampling is an option. <br /> Non-friable category I materials that contain trace amounts of asbestos as determined by PLM are reported as non- <br /> asbestos containing materials.Additional sampling is an option. <br /> Additional sampling and/or analysis to verify asbestos content is an option for any material. <br /> ADDITIONAL SAMPLING/ANALYSIS RECOMMENDATIONS <br /> y Non-friable organically bound(NOB) materials found to be non-ACM by PLM are recommended to be analyzed by TEM to <br /> confirm negative results for all renovation projects or for demolition projects where concrete is to be recycled. <br /> v Laboratory analytical results may vary for a sampled material. Additional analysis for a material may be done or <br /> ' recommended if it is discovered that differing results for the same material exist.The definition of a homogeneous area as <br /> used by an asbestos inspector may differ from a laboratory's usage of the word homogeneous. The color description by <br /> the lab may differ from the color description used by an inspector. <br /> r If a prior inspection report exists for any of the materials sampled within this report,the results may be contradictory. If <br /> client knows a prior report exists and was not provided to IDEAL for review, IDEAL recommends a careful review for <br /> tcontradictory results and TEM analysis considerations. <br /> TEM results supersede PLM results. <br /> ' When trace amounts of asbestos are detected by TEM, a material is reported as non-asbestos containing. <br /> When trace amounts of asbestos are detected in terrazzo materials as determined by TEM,they are reported as non-asbestos <br /> containing. However,we recommend against sanding such materials for maintenance purposes. <br /> ' It is often difficult to penetrate a terrazzo material for a core sample without causing destructive sampling to it. Other suspect <br /> asbestos containing materials may exist below the hard terrazzo top surface(such as a soft mud bed, etc.).Therefore, if any <br /> material is found below the hard top surface during renovations, additional inspection service is necessary. <br /> The inspection is limited and excludes exhaustive sampling and analysis methods to verify a material's asbestos content. For <br /> instance, unless otherwise noted, the inspection service excluded verifying (by TEM)the asbestos content of all materials <br /> containing greater than 1%asbestos as determined by PLM as well as verifying the asbestos content of all materials in which <br /> ' no asbestos (or trace amounts) of asbestos were detected by PLM. <br /> The area estimates shall not be used for bidding purposes.All quantities and conditions that affect costs for asbestos removal <br /> and disposal must be verified.Area estimates may include materials known/assumed to be present behind walls, above <br /> ' ceilings, inside boilers, under floors, etc. <br /> This report is not a specification for removal of asbestos containing material, nor shall it be used as such. <br /> The inspection service excluded any inspection for the presence of mold or other contaminants. IDEAL shall not be held <br /> responsible for disturbance of any mold or other contaminants or amplification of same. <br /> At least one representative trained in the provisions of 40 CFR Part 61, Subpart M, is to be on site during demolition or <br /> ' renovation.The person is to have in his or her possession evidence that the requisite training has been accomplished.The <br /> person is to ensure that if additional quantities of known or suspect asbestos containing materials are found, applicable <br /> asbestos rules will be followed. <br /> This report was completed based on our interpretations of regulations. Changes in accepted practices or in applicable <br /> regulations cannot be anticipated and have not been addressed. <br /> This report shall not be reproduced, except in full,without the written consent of IDEAL. IDEAL may not retain records for more <br /> ' than one year.
