The primary reference for basic guidance on the remediation of visible mold growth shall be the Environmental Protection Agency guidelines, as published in Mold Remediation in Schools and Commercial Buildings

For situations resulting from clean water intrusion, Table 2 summarizes recommendations for containment and personal protective equipment based on the type of material affected, and the total surface area contaminated. 

Depending on the material(s) affected and the extent of contamination, a professional remediation contractor may be warranted.

The Standard and Reference for Professional Mold Remediation, ANSI/IICRC S520-2008, as published by the Institute of Inspection, Cleaning and Restoration Certification, shall be referenced for larger-scale remediation projects


The District of Columbia Mold Assessment and Remediation Regulations, 20 DCMR Chapter 32, defines additional requirements for mold assessment and remediation in residential properties.
The following procedures shall apply to Nugent Hall, Curley Hall and Curley Annex. Student dormitories are exempt from the following requirements.

Licensing: Individuals conducting assessment and remediation activities for areas of indoor mold growth affecting ten square feet (10 SF) of surface area or more, must be appropriately licensed.

Written Work Plans: Remediation plans for areas greater than or equal to 10 SF must be documented and submitted to EHS prior to the commencement of work.  Plans must include details regarding containment methods; signage; products utilized during the remediation process including disinfectants, biocides and detergents.

Notifications: The District Department of Energy & Environment shall be notified when 10 SF or greater of visible mold growth is identified in a residential building subject to regulation.  Notification must be made no more than 5 calendar days after the mold is identified. Additional notification of planned remediation shall be made at least 5 calendar days prior to the start of work.

Notification requirements for planned remediations may be waived in the event of an emergency.  In such cases, notification may be made no later than one business day after the emergency arises.

Post-Remediation Verification: Protocols to ensure the successful completion of the remediation must be defined.

Additional Guidelines: For remediation of areas less than 10 SF, when performed by non-licensed individuals, follow procedures involving visual inspections, clean-up methods and minimum personal protective equipment.
