Asbestos Decontamination: Disturbance of Asbestos Containing Material

ACM Disturbance, Handling and Removal Procedures

The following procedures shall he followed during the conduct of abatement activities:

Abatement of asbestos-containing materials shall be by wet methods. Dry removal of asbestos-containing material is prohibited, unless EPA approval has been obtained. The EPA-approved alternate removal plan shall be submitted to the Department for approval a minimum of 15 days before work is scheduled to begin or begins. The plan shall explain and justify why ACM must be removed dry and how asbestos fibers will be controlled to prevent their release.

When amended water is used, the ACM shall be sprayed with sufficient frequency and quantity for enhanced penetration. Sufficient time shall be allowed for penetration to occur prior to removal action or other disturbance taking place. Accumulation of standing or free water is prohibited. Fluffy friable materials shall be saturated. Non-hygroscopic materials, such as tremolite or amosite, shall be thoroughly wetted on all surfaces while work is being conducted.

When used, removal encapsulants that minimize fiber generation and enhance penetration, shall be applied per manufacturer's specifications and in accordance with federal guidelines.
