| (a) Clearance criteria. For a remediation project to
achieve clearance, a licensed mold assessment consultant shall conduct
a post-remediation assessment using visual, procedural, and analytical
methods. If walk-in containment is used during remediation, the post-remediation
assessment shall be conducted while the walk-in containment is in
place. The post-remediation assessment shall determine whether:
(1) the work area is free from all visible mold and
wood rot; and
(2) all work has been completed in compliance with
the remediation protocol and remediation work plan and meets clearance
criteria specified in the protocol.
(b) Underlying cause of mold. 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 cause.
(c) Analytical methods.
(1) The assessment consultant shall perform a visual,
procedural, and analytical evaluation in each remediated area in order
to determine whether the mold contamination identified for the project
has been remediated as outlined in the remediation protocol.
(2) The consultant shall use only the analytical methods
and the criteria for evaluating analytical results that were specified
in the remediation protocol, unless circumstances beyond the control
of the consultant and the remediation contractor or company necessitate
alternative analytical methods or criteria. The consultant shall provide
to the client written documentation of the need for any deviation
from the remediation protocol and the alternative analytical methods
and criteria selected, and shall obtain approval from the client for
their use, before proceeding with the post-remediation assessment.
(3) Where visual inspection reveals deficiencies sufficient
to fail clearance, analytical methods need not be used.
(d) Passed clearance report. An assessment consultant
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. The report must include the following:
(1) a description of relevant worksite observations;
(2) the type and location of all measurements made
and samples collected at the worksite;
(3) all data obtained at the worksite, including temperature,
humidity, and material moisture readings;
(4) the results of analytical evaluation of the samples
collected at the worksite;
(5) copies of all photographs taken by the mold assessment
consultant; and
(6) a clear statement that the project has passed clearance.
(e) Final status report. If the mold assessment consultant
determines that remediation has not been successful and ceases to
be involved with the project before the project passes clearance,
the consultant shall issue a written final status report to the client
and to the remediation contractor or company performing the project.
The status report must include the items listed in subsections (d)(1)
- (5) and any conclusions that the consultant has drawn.
