1.0 Executive Summary

Landmark Environmental, LLC (Landmark) was retained by Anderson Engineering (Client) to conduct a pre-renovation asbestos survey (Survey) as part of a renovation project at the Veterans Affairs (VA) Central Iowa Health Care System, located in Des Moines, Iowa

(the Property). The Client intends to conduct a remodel project titled “636A6-22-104

Building 11 Replace Boiler Plant Brine Tank” (Project). Only locations and materials to be impacted during this Project were included in the Survey. The Survey was conducted on August 21, 2024.

A summary of the Survey results are as follows:

Landmark collected 13 bulk asbestos samples as part of the inspection. The contracted laboratory, EMSL Analytical, Inc. (EMSL) separated these 13 samples into 14 individual layer samples and all 14 individual layer samples were analyzed.

Based on the laboratory report, no suspect building materials were found to contain asbestos.

No building materials were assumed to contain asbestos during the Survey.

Electrical wiring and panels were not sampled. Landmark does not perform bulk sampling of electrical equipment unless it has been shut down and tagged by a licensed electrician.

Since the building and brine generation tank system was operating, a complete destructive survey could not be conducted. No attempt was made to locate materials inside walls, doors, tanks and other areas that would require destructive entry. The possibility exists that materials may be present in these locations. Materials observed, or suspected in these areas, are assumed to be ACM. The possibility exists that as these locations are opened up during renovation, suspect material will be found. If suspect materials are encountered during renovation, work should stop immediately and the materials should be sampled for asbestos content or assumed to contain asbestos and properly removed by a licensed asbestos abatement contractor.

This Survey identifies asbestos as they existed on the day of the survey at the Property.

Conditions may change over time.

This Survey should not be used as a bidding document. The ACM quantities provided are estimates and must be verified by the bidding contractors.

3.0 Sampling Methods and Analysis

3.1 Bulk Asbestos Sampling

Building diagrams were utilized to divide the Property building into functional spaces for the purposes of describing sampling locations. The building diagram with sample locations has been included in Appendix B.

Similar systems and materials were grouped into “homogeneous areas of building materials” (homogeneous materials). Homogeneous materials often exist in more than one functional space within the Property building. Each homogeneous material was assigned a discrete number; the homogeneous material number is indicated in the first number of the sample name. Multiple samples of each homogeneous material were taken in accordance with the EPA-Asbestos Hazard Emergency Response Act (AHERA) guidelines using a random sampling procedure. These multiple samples were designated “A, B, C,” etc. for each homogenous material, as indicated in the sample name. The sample locations and sample descriptions are shown on the building diagram and the asbestos laboratory report in Appendix B.

Samples were collected by carefully removing a small representative sample of the suspect material and sealing it in a plastic bag.

3.2 Bulk Asbestos Analysis

Landmark collected 13 bulk asbestos samples as part of the inspection. The contracted laboratory, EMSL separated these 13 samples into 14 individual layer samples and all 14 individual layer samples were analyzed. The results are presented in the attached laboratory report in Appendix B.

The bulk samples were analyzed by polarized light microscopy (PLM) with dispersion staining, EPA method 600/R-93/116 and EPA method 600/M4-82-020. Quantity determinations are made by visual estimation. For each homogeneous material, once a positive sample was identified, the remaining samples were not analyzed.

EPA National Emission Standards for Hazardous Air Pollutants (NESHAP)-Rule 40 CFR

Part 61 states that samples found to contain less than 10% asbestos by visual estimation may be further quantified by point count analysis.

The Asbestos rule states that all multi-layer systems, except for wall systems where joint compound was used only at the joints and nail holes, must be analyzed as separate materials. If any layer contains greater than one percent asbestos, that layer must be treated as asbestos-containing. This requires all layers in a multi-layered system to be

F:\PROJECTS\AND-Anderson Engineering\Des Moines Brine Tank 636A6-22-104\Asbestos Survey\Building 11 Brine Tank Project

- Pre-Renovation Asbestos Survey Report.docx treated as asbestos-containing if the layers cannot be separated without disturbing the asbestos-containing layer.

Asbestos samples will be held for 30 days after the date of this report.

3.3 Chain of Custody Procedures

To ensure that samples collected in the field are neither lost nor their identity mis-identified, all samples, from the point of collection to receipt in the laboratory, proceeds as follows. Each sample is first assigned a unique and distinct sampling number. After a sample is placed into a plastic bag, that unique number is assigned to that bag. This same number is documented on the laboratory’s chain of custody. The inspector signs each chain of custody before delivering to the lab. Upon receipt of the samples, the lab analyst verifies that each sample matches the corresponding chain of custody number and signs and dates the chain of custody. After analysis, the analyst generates a report that includes the sample results and the project chain of custody forms.

4.0 Asbestos-Containing Material Assessment

In each functional space, each homogeneous material was quantified and assessed for friability (i.e. material can be crumbled, pulverized, or reduced to powder by hand pressure when dry). Suspect ACM was then assessed as to their condition and potential for disturbance. This information was recorded on the asbestos physical assessment shown in Appendix C. The model for this system is described in the EPA Draft

Curriculum for Training Building Inspectors.

EMSL maintains liability limited to cost of analysis . Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations . The report reflects the samples as received.

Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 “Interim Method”) but augmented with procedures outlined in the 1993 (”final”) version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non- friable organically bound materials present a problem matrix and therefore EMSL recommends gravimetric reduction prior to analysis . Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Estimation of uncertainty is available on request.
