Meth Lab Cleanup >> Drug Lab Clean-Up

Burning a meth-contaminated structure in lieu of decontamination is prohibited, unless priorapproval has been granted. Approval shall be obtained from the Kentucky Division for Air Quality Drug Lab Clean-Up prior to a training or practice burn. Safety of firefighter entry into a former meth lab structure and effectivenessof decontamination of firefighter equipment cannot be assured. In all cases of a practice or training burn,the burn shall be done in accordance with demolition and asbestos regulations.
 
VI. POST-DECONTAMINATION SAMPLINGA.
 General Sampling IssuesPost-decontamination samples shall be taken after washing and sealing/painting of surfaces. The Drug Lab Clean-Up certified contractor may take wipe samples after washing of surfaces only if the decontamination standardhas been achieved. However, the sealing/painting step helps to provide an additional layer of protection.Some studies have shown that elevated levels of meth may "wick” through the paint, but if the doublewashing is done, it is anticipated that the main meth mass shall be removed before painting or sealing
 
B. Sampling ProtocolsEach room and space in the inhabitable property shall be sampled. Procedures for meth wipe samplingare provided in Appendix B.1. In all cases, a representative number of discrete samples shall be biasedand collected in the areas of Drug Lab Clean-Up suspected cooking, observed chemical spills, or waste storage areasidentified during the Preliminary Assessment of the inhabitable property. Table 3 lists the minimumnumber of composite samples that shall be required for post-decontamination sampling. All samples shallbe collected from cleaned surfaces and not new materials.
 
 If a wall or material identified below isremoved and replaced as part of the decontamination, the contractor can designate another location forsampling and document in the Contractor’s Certificate of Decontamination, DEP 5035, January 2009.Table 3Post-Decontamination Sampling ProtocolsArea Sampling ProtocolEach Room (4) ten cm x ten cm samples for total of 400 sq. cmconsisting of :(1) sample from location at or near center of floor*(1) sample from Drug Lab Clean-Up location at or near center of ceiling(1) sample from location at or near center of (2) walls(Samples can make up one (1) composite sample foreach room) + the following samplesKitchen (4) ten cm x ten cm samples for total of 400 sq. cmconsisting of:(1) sample from countertop(1) sample from stovetop(1) Range hood above stovetop (if present).

If multiple appliances arepresent, up to four (4) wipes can be Drug Lab Clean-Up combined into onecomposite sample representing 400 sq. cm.* If the flooring is carpeting that has only been cleaned and not removed, the floor sample can betaken from the lowest point on one wall nearest the cooking area, or just above the baseboard innon-cooking rooms.
 
All samples collected and analyzed shall be below the decontamination standard of 0.1 µg/ 100cm2. Inaddition to the samples noted in Table 3, the certified contractor shall also collect Drug Lab Clean-Up quality assurance andquality control wipe samples and field blanks in accordance with standard sampling and analyticalpractices. The contractor shall log all samples collected at the site and any QA/QC samples on a chain ofcustody form, maintain proper temperature and maintain records of sample shipment to the laboratory.
 
C. Analytical Laboratory RequirementsCertified contractors shall be required to use an EPA or otherwise nationally-accredited analyticallaboratory to ensure that all analytical data are reliable and reproducible. For methamphetamineanalyses, the laboratory must utilize Method 8270C-Modified, "Semi-volatile Organic Drug Lab Clean-Up Compounds byLiquid Chromatography or Gas Chromatography/Mass Spectroscopy”, from "Test Methods for EvaluatingSolid Waste, Physical/Chemical Methods”, U.S. EPA SW-846, Third Edition (Nov. 1986), Revision 3(Dec. 1996), or other accredited laboratory methods to achieve a detection limit of at least 0.1 µg/ 100cm2, and include all quality assurance/quality control documentation required by the method.
 
 Many laboratories are certified in other states to analyze for meth and other precursors or are using updatedmethods and equipment that are equivalent to Method 8270. Data from these laboratories shall Drug Lab Clean-Up beaccepted. For all other waste or chemical analyses requiring an off-site environmental laboratory, EPASW-846 methods must be utilized. It is the responsibility of the certified contractor to ensure thatthe laboratory used is an accredited laboratory and is capable of performing the requiredanalyses.
 
VII. EXTERIOR EVALUATIONA.
Septic System EvaluationLarge volumes of meth lab wastes can pose a problem if they are flushed and end up in a septic Drug Lab Clean-Up system.It is believed that the micro-organisms present in the septic system can biologically break down many of the chemicals, however if a meth lab operated for a long period of time, under extreme pH conditions, itcould cause damage to the operation of the system.
 
 If there is evidence that meth lab wastes may havebeen disposed into the septic system, field screening of the septic tank must be performed by thecertified contractor. Evidence of waste disposal may include the following: witness statements; stained oretched sinks, bathtubs, toilets; chemical odors coming from plumbing or septic tank; or visualobservations of unusual conditions within the tank (dead tank); or stressed or dead vegetation in a drainfield; or if identified on Tier Assessment form.
 
 Initial field screening during a Tier 3 response selection shall include monitoring the septic tank for VOCsusing a PID or FID; and testing the pH of the liquid in the septic tank using pH paper or pH meter.Additional screening or testing shall be performed according to the Tier response level. Samples shall becollected of the septic wastes in the tank for toxicity characteristic leaching procedure (TCLP) and otherwaste characterization parameters Drug Lab Clean-Up to determine if the wastes are hazardous, and arrangements shallneed to be made with an approved waste handling contractor, transporter, and disposal facility to havethe septic tank contents pumped out and properly disposed in accordance with state and federalregulations. Do not remove or dispose of the tank contents until proper testing has been done.
