CCDAQM is the delegated agency for the enforcement of the Asbestos NEHAP in Clark County Nevada. The regulations require a thorough inspection where the demolition or renovation activities will occur. The regulations require the owner or the operator of the renovation or demolition operation to notify CCDAQM before any demolition that contain a certain threshold amount of regulated asbestos-containing material. The rule requires work practice standards that control asbestos emissions. Work practices often involve removing all asbestos-containing materials, adequately wetting all regulated asbestos-containing materials, sealing the material in leak tight containers and disposing of the asbestos-containing waste material as expediently as practicable, as the regulation explains in greater detail.

ASBESTOS & LEAD SAMPLING SUMMARY

Terracon has completed asbestos and lead paint surveys in accordance with Terracon Proposal

Number P64217189, dated October 28, 2021, and LGA Architecture Task Order

140P2022F0029, dated December 6, 2021 for all sites. The surveys were performed to support the planned demolition of structures and utilities with associated with returning noncritical sites to their natural conditions.

Terracon has prepared this summary detailing the number of samples collected and the distribution of samples in reports submitted in this submittal, reports submitted for review, and reports in progress where additional materials require assessment that is included in the submitted ASR. The numbers of samples are estimates from invoicing and may include samples where additional analysis was required due to exceeding the laboratory’s standard analysis based on exceed the number of layers (i.e., roofing and flooring samples. Table 1 below summarizes the number of suspect asbestos and lead-based paint samples collected from each structure/area for reports included in this submittal. Table 2 below summarizes the number of suspect asbestos and lead-based paint samples collected from each structure/area for reports submitted for review (in progress). Table 3 below summarizes the number of suspect asbestos and lead-based paint samples collected from each structure/area for reports for areas where additional materials require assessment that is included in the submitted ASR. Terracon has exceeded the asbestos sample budget by 554 samples. There is a negative balance of 53 lead samples. The additional samples and the level of effort to collect additional samples and complete the remaining reports is included in the submitted ASR. Table 4 below summarizes asbestos-containing materials identified in the reports included in this submittal. Table 5 summarizes identified lead-based paint (LBP [.5 percent lead]) in the reports included in this submittal.

A summary of the ACM identified in the Echo Bay Hotel & Restaurant is provided below to assist the project team with insight of the amount of ACM that may be present in reports that are submitted for review and reports in progress where additional materials require assessment.

Additionally, many of the “boneyard” areas have materials that would require additional assessment that could impact costs and schedule of the project.
