§ 947. Post-remediation assessment and clearance. 1. For a remediated project to achieve clearance, a mold assessment licensee shall conduct a post-remediation assessment. The post-remediation assessment shall determine whether:

(a) the work area is free from all visible mold; and

(b) all work has been completed in compliance with the remediation plan and remediation work plan and meets clearance criteria specified in the plan. 2. Post-remediation assessment shall, to the extent feasible, determine that the underlying cause of the mold has been remediated so that it is reasonably certain that the mold will not return from that remediated area. If it has been determined that the underlying cause of the mold has not been remediated, the mold assessment licensee shall make a recommendation to the client as to the type of contractor who could remedy the source of the mold or the moisture causing the mold. 3. A mold assessment licensee who determines that remediation has been successful shall issue a written passed clearance report to the client at the conclusion of each mold remediation project. 4. If the mold assessment licensee determines that remediation has not been successful, the licensee shall issue a written final status report to the client and to the remediation licensee and recommend to the client that either a new assessment be conducted, that the remediation plan as originally developed be completed, or the underlying causes of mold be addressed, as appropriate.
