Via a recent edition of IAQ Radio, IICRC Chairman Darrell Paulson announced that ANSI has officially withdrawn approval of the S520 Standard and Reference Guide for Professional Mold Remediation.

According to the show episode, and the IAQ Radio Blog, ANSI withdrawal stems from an audit that found deficiencies in record keeping and documentation. The IICRC has hired a standards development consultant to improve the document.
