PubliC ~sslstaml' Branch NO\l'lllbl'r 7,2006 Page I of4 MOLD REMEDIATION Overview Extensive disaster-related damages may result in public facilities becoming inundated or exposed to wet and humid weather conditions for extended periods of time. The limited availability of repair and restoration contractors may delay clean-up activities. In addition, the disruption of electrical power can inhibit the use of water extraction, pumping and drying electric equipment. As such, the damaged structures and their contents may remain waterlogged until power is restored and remediation can begin. Such water saturation may cause growth and propagation of mold on structures and interior contents, causing health-related problems and increasing the cost of repairs. The following guidance is provided to assist Public Assistance staff and applicants (entities that meet the requirements of 44 CFR 206.222 -State, local governments, Indian tribes or authorized tribal organizations, and certain private non-profits) with the remediation and/or repair of their damaged facili ties. Determining Eligibilit of Mold Remediation Costs • The cost of mold sampling, both pre-and post· remediation, may be eligible for reimbursement, provided there is evidence prior to remediation to indicate the existence of disaster-related mold. • The cost of mold sampling which reveals no presence of disaster-related mold is not eligible for reimbursement. • Costs to perform eligible remediation -either through force account or a contractor -may be eligible for reimbursement. Contractor costs are subject to the contract procurement requirements in 44 CFR 13.36. • The following remediation activities may be eligible under Category B: o Wet vacuuming, damp wiping or HEPA vacuuming of the interior space. o Removal of contaminated gypsum board, plaster (or similar wall finishes), carpet or floor finishes, and ceilings or permanent light fixtures. o Cleaning of conlaminated heating and ventilation (including ductwork), plumbing, and air conditioning systems, or other mechanical equipment. MOLD REMEDIATION • Ifan applicant fails to take reasonable measures to prevent the spread of mold contamination to a facility, the rehabilitation and repair of the additional contaminated area will not be eligible for federal assistance. • If an applicant can document and justify why reasonable measures were not taken to prevent further contamination to a facility from mold, or why reasonable measures taken were insufficient to prevent further damage, remediation activities may be eligible for reimbursement. Examples of extenuating circumstances may include: o Disruption of power. o Facility remained underwater. o Inability to access the facility due to the disaster, Le. debris blocking access routes and facility. o Facility HV AC equipment damaged due to the disaster. o Insufficient resources to remediate the entire facility. Identification • Mold contamination or associated damages, identified by the applicant, must be a direct result of the disaster. Situations that are not obvious will require a closer examination, usually with the assistance of an Industrial Hygienist. • It is the responsibility of the applicant to show evidence of mold contamination or damage during the inspection. Sampling may not be necessary; however, applicants may choose to conduct pre-or post-sampling by an experienced professional to ensure proper or adequate remediation. • The applicant may provide an Industrial Hygienist's report to support its request for assistance. Remediation • The method of remediation will depend on the types of material that are damaged and the extent of damage. Accordingly, applicants may employ a variety of mold cleanup methods to remediate mold damage, as appropriate to the characteristics of the situation. • The following charts provide guidance on sizing the scope of the remediation effort and mold remediation methods and their application. This information is not all encompassing, but is provided as a general reference for an applicants' consideration when developing a scope of work for force account or a request for bid/proposal.
