Notice of Final Approval for an Alternative Work Practice Standard for Asbestos Cement Pipe Replacement
On May 30, 2019, EPA approved an alternative work practice, called close tolerance pipe slurrification (CTPS), that can be used to comply with the Asbestos NESHAP. As the infrastructure of municipalities age, utilities need to replace deteriorated water pipes made of asbestos cement, which can be problematic and costly because pipes run beneath and beside major roadways, buildings and overlap other utilities (e.g., gas, electricity). This work practice provides utilities with a method of removing and replacing asbestos cement pipes that is as protective of human health and the environment as the Asbestos NESHAP.
