In 2007, Hawaii adopted Chapter 11-452 as part of the Hawaii Administrative Rules entitled “Requirements for the Decontamination and Cleanup of Methamphetamine Manufacturing Sites.” Contractors completing decontamination of meth labs must be trained and certified as DEA Hazardous Waste Cleanup and Disposal Contractors, however regulations allow the property owner to complete decontamination and subsequent sampling. Remediation contractors should be licensed and bonded, have current 40-hour HAZWOPER training, and provide suitable PPE. . If items are visibly stained they must be removed and disposed of, however all non-porous items may be decontaminated using hot water and detergent cleaning of at least 3 times. Note that wood and granite countertops are considered porous and must be removed and replaced. All floor/wall fans and exhaust vents over stoves/ranges must be removed and disposed of. The ventilation system may be decontaminated. Sampling contractors should be licensed and insured, qualified environmental air sample (Certified Industrial Hygienist is recommended but not required), suitable PPE, and be familiar with sampling protocols. . Wipe samples must be 0.1ug/100cm² or non-detect to achieve full remediation. If the remediation samples are not successful in achieving acceptable levels encapsulation of paintable surfaces with two coats of oil based paint or Kilz is recommended. Note that spray on ceiling surfaces that are not removed must be encapsulated by spray painting with two coats of oil-based paint. The hazard evaluation and emergency response office will oversee reports and testing needed for clearance. These guidelines do not refer to user sites.
