Methamphetamine Decontamination 7090 W. 29th Place Caldwell Environmental Associates, Inc. 6300 E. 58thAvenue, Suite K Commerce City, CO 80022 Table of Contents /ip AVERY READY INDEX' INDEXING , I Methamphetamine Drug Lab Analytical Report EXECUTIVE SUMMARY On February 26, 2003, Michael Corcoran of Caldwell Environmental Associates conducted a methamphetamine drug lab assessment of 7020 West 29th Place in Wheat Ridge, Colorado. As a precaution, the West Metro Drug Task Force had requested that testing be conducted to determine the levels of drug lab related contamination present. The intent of the survey was to determine whether there was methamphetamine -related contamination present in the residence, although there is no identified cleanup clearance level specified by the State of Colorado. The State of Colorado Health & Environment has put together a draft which recognizes an allowable level of methamphetamine contamination of less than 5 micrograms / square ft. (ug/f2). The Tri -County Health which includes Adams, Arapahoe, and Douglas Counties has also implemented those same standards in which Colorado drafted. The survey included an evaluation of the residence for airborne volatile organic compounds, corrosive (acids and bases), and methamphetamine surface contamination. On the day of the survey, seven surface samples and one background sample were collected from the interior of the residence. All the drains in the bathroom and kitchen were checked for possible corrosive or organic solutions. The results of the survey indicated that there were corrosive surface contaminations on the kitchen counter tops and flooring. There were no indications of airborne volatile organic compounds detected in the house. The methamphetamine surface samples collected indicated a high level methamphetamine contamination in excess of the Washington standards. SITE OVERVIEW The property consists of a three bedroom, and one bath single story house. It is located on a standard city block in Wheat Ridge, Colorado. The property is served with city water and sewer. A diagram of the property is included as an attachment to assist in the visualization of the property and layout. On the day of the survey, the house was full of all household items and debris. The surfaces of the house (floors, sinks, counter tops, etc.) appeared not to have been cleaned prior to the survey. The interior walls and ceilings of the residence are a combination of painted sheet rock, plaster, wallpaper, and paneling; the floors are a combination of vinyl, wood, and carpeted flooring. The range/oven, microwave and refrigerator were still present in the kitchen. A visual inspection was conducted, which indicated drug lab related activities present (matches with no striker plates, stains on walls, counters and flooring). Distinct odors, which are characteristically associated with illegal manufacturing of methamphetamine, was noted in the residence on the day of the survey. There was drug lab -related paraphernalia observed in the residence or on the property. A walk -around survey of the property did not reveal any evidence, which would indicate drug lab -related spills or dumping. CONCLUSION All guidelines and threshold values set forth in the Colorado standards draft have not been met. It is recommended that the removal of all absorbable materials be removed and that the house be professionally cleaned.. After these recommendations have been met, the house should be deemed clean and ready for continuous occupancy under or according to those standards.

In response to increased concerns over the • left behind at meth labs, the Colorado Department of Public Health and Environment (the Department) has put together the following guidance to assist • agencies, property owners, and the general public in addressing contamination at former meth labs. I ............. 701MMEM410- =-am M- "a'"AMMM"SA #M the cleanup. .......... ........... contamination in outdoor areas, in appropriate circumstances, under water quality, solid waste and/or i• waste statutes and regulations. Local Health Authorities W= Colorado Department of Public Health and Environment Emm Section 16-13-303 includes a specific provision classifying buildings, vehicles and real property that are used in connection with crimes related to illegal drugs as Class I public nuisances. Some local health departments rely on building departments to initiate and require the clean up of the property and to not allow re -occupancy until local "clean up standards" are met as determined by the health officer. Whether this is possible in your area depends on what has been adopted into local ordinances. As an example refer to the Uniform Building Code or the Uniform Housing Code (Chapter 10, Substandard Buildings). Other codes that may be useful include the Uniform Code for the Abatement of Dan-er us Buildin-s (Section 3 1 1 1 . a or the International Property Maintenance Code (Section 109). Some local health departments assist UdIdirig; 4e,?,,?,Aments by-ietomhiiag when 1macceptably unhealthy c*rriitions exist for the steictxro to be considered unsuitable forhuman habitation and in determining when these conditions are sufficientlyreduced. Solid Waste Statutes X-TRWYM=7#47 referenced. However, in the context they are used it appears to be a difficult leap to meth lab enforcement. Amore universal section is 30-20-1100) of the minimum standards. Section 30-20-1100) reads: "Such minimum standards shall require the reporting, documentation, or remediation of spills at illegal disposal sites, abandoned disposal sites, or contaminated sites". This section has been used to require cleanup of petroleum and antifreeze spills and could be used to respond to meth lab sites. Prior to beginning cleanup of a former meth lab, a preliminary assessment should be conducted to determine what chemicals are involved, the manufacturing method, and whether the property is fit o unfit for use as is. There are many meth, "recipes" and manufacturing methods. Identifying the chemicals used and the drugs being made at the laboratory will help to determine what kind of chemical sampling may be necessary. The drug lab seizure report and the hazardous material From this information, a lab site chemical inventory can be developed. The chemical inventory will help to identify potential chemical hazards and the manufacturing method used. The prelminnary assessment should be reviewed by the local health department, or other oversight agency, to evaluate the potential contamination and health risk. The oversight agency will determine whether the property is fit or unfit for use, and whether cleanup or decontamination is necessary. in some areas, this determination may be made by the local building department or other local agency with authority to designate a property as fit or unfit for use. If it is determmied that cleanup is necessary, the property owner may wish to contact their insurance company to determine whether property or homeowner's insurance can be used to cover cleanup costs. Methods of Manufacturing The manufacture of meth is fairly simple. Generally, meth is made by using a "recipe" obtained from acquaintances, publications or other sources. The person manufacturing the drug literally "cooks" the WM Colorado Department of Public Health and Environment MEM ingredients, Hence these people are called "cooks." Though there are a number of methods used to produce this drug, the two most common methods currently found in Colorado include the Red Phosphorus and Birch methods. Both use ephedrine or pseudoephedrine as a primary ingredient, These chemicals are present in many cot. on over-the-counter cold and asthma medications. 11-IMIRMMMM • M NO 11 M MV#11'n v�-g sodium chloride (salt), toluene, naphtha, freon, ethyl ether, chloroform, and methyl -ethyl -ketone (MEK). Wastes generated include potentially flammable extraction process sludges and hydrogen chloride gas. Other methods to manufacture meth include the amalgam method, which primarily uses phenyl-2- propanone (P2P) and methylamine. Mercuric chloride, aluminum, hydrochloric acid'. isopropyl alcohol, methanol, ethanol, acetone, benzene, chloroform and ether are also associated with this manufacturing method. Potential areas of contamination can be divided into primary and secondary areas. Typical primary areas of contamination include: # Processing or "cooking" areas: Gross contamination in these areas may be caused by spills, boil -overs, explosions, or by chemical fumes and gases created during the heating and distilling portions of the "cooking" process. Indoor areas affected may include floors, walls, ceilings, used glassware and containers, working surfaces, furniture, carpeting, draperies and other textile products, plumbing fixtures and drains, or beating and air-conditioning vents. Outdoor cooking areas could involve picnic tables, camping stoves, or other outdoor areas where cooking could occur. Um Colorado Department of Public Health and Environment Disposal areas: Indoor areas include sinks, toilets, bathtubs, plumbing traps and floor drains, vents, vent fans and chimney flues. Outdoor areas may include $oil, surface water, groundwater, dumpsters, sewer or storm systems, septic systems and cesspools. * Storage areas: Contamination may be caused by leaks, spills or open containers. 11MMMEMMEM Common areas in multiple dwelling structures and adjacent apartments or rooms may also be contaminated, including contamination of floors, walls, ceilings, furniture, carpeting, light fixtures, blinds, draperies and other textile products. * Common ventilation or plumbing systems in hotels and multiple dwellings. TrI717TWIT e enforcement and/or a hazardous materials (hazmat) cleanup team. After a site has been secured and no longer subject to criminal investigation, appropriately trained and equipped personnel should be hired to cleanup any remaining contaminated materials. If suspicious containers or lab equipment are found on a property, untrained personnel should leave the area and contact the local fire department or law enforcement agency. IRMO with the local health department (refer to the Post Cleanup Assessment for Structures and Re- • V" 'ARL&Ls", may only be accomplished by demolition of the contaminated structure, In most situations, cleanup/decontamination will involve one or more of the followmig measures. Appropriate personal protective equipment (PPE) must be worn at all times during the cleanup. MM =- MM Colorado Department of Public Health and Environment MEM After clean up, the property should be aired out for three to five days. Then the property should be checked for re -staining or odors, either of which would indicate that the initial cleaning was not successful and that more extensive steps should be taken. Gross Cleanup where acids or bases are known to be sources of contamination, the potential for harmful effects may be reduced or removed through neutralization. Acids may be neutralized with solutions of sodium icark ate 4,akiyp KVIMMMV^��M�W MOM"WWWOM" related chemicals. If meth lab chemicals are present, the contents of the tank should be disposed of as either a solid or hazardous waste, based on the results of analysis. Analysis of the septic tank contents should be based on chemicals determined to be part of the lab site chemical inventory (developed as part of the preliminary assessment). bly contaminated (etched or stained) sinks, bathtubs, and toilets are difficult to clean and may need to be removed and replaced. Absorbent materials, such as carpeting, drapes, furnishings, wallpaper, clothing, etc., can absorb vapors and may collect dust and powder from the chemicals involved in the manufacturing process. Some absorbent materials can be safely washed or cleaned by other methods if they exhibit little to no odor or staining, but many stained materials or those with odors will have to be disposed of in a solid waste landfill, with prior approval according to the type and degree of contamination. Generally, cleaning costs for these items exceed replacement costs. Prior to transporting waste to a landfill, the facility should be notified that the waste stream is from a former meth lab so that the landfill can take the proper measure to handle it appropriately. M W= Colorado Department of Public Health and Environment July 2003 Cleaning of porous rnaterials that are not discarded will usually consist of vacuuming using a machine equipped with a HEPA filtration system, followed by hot water detergent scrubbing. Non -washable materials, such as lined curtains, that are not heavily contaminated can be steam -cleaned. In cases of mild to moderate contamination, pre -testing should not be necessary, if the cleanup protocol includes through detergent cleaning. If property owners wish to avoid cleaning or disposal of goods, pre -testing will generally be required. Depending on the material, a sample of fabric may need to be collected for laboratory analysis. Ventilation System Ventilation systems tend to collect fumes and dust and redistribute them throughout a structure. vents, ductwork, filters and even the walls and ceilings near ventilation ducts can become contaminated. All air filters in the system should be replaced, vents should be removed and cleane the system's ductwo& should be cleaned, and surfaces near inlets and outlets should be cleaned. I UW 7•DUCT FNJ Fliraj--seTw more than one unit or structure. These connections must be considered when evaluating cleanup and testing procedures. One strategy is to take samples from adjacent or connected areas/rooms/units, working outward from the lab site until samples show low levels or no contamination. Interior surfaces (e.g., walls, wood flooring, ceilings, and paneling) should be painted with an based paint, epoxy, or other material suitable to create a physical barrier capable of preventing contact with, or volatilization of contaminants. Complete coverage may require more than one coat. The painted areas should be monitored and the barrier maintained to assure that the contamination is contained. If staining, odors or discoloration appear after the coating dries, further cleaning or removal and replacement of the surface may be necessary. W= two the local POTW should be advised that chemicals associated with meth production might have been disposed of down the sanitary sewer. Do not conduct any invasive measures to eliminate the odors, If air reactive chemicals (such as phosphorus or lithium metal) are present, exposure of these chemicals to air may result in ignition. The plumbing system should be flushed with generous amounts of water to reduce the concentration of residual chemicals. If contamination of a septic tank or leach field is suspected, contact the local health department or environmental health service to determine if the local Individual Sewage Disposal System Regulations address such an issue. Personal Belongings Z= Colorado Department of Public Health and Environment mmm should be decontaminated using a detergent- water wash, or similar cleaning method, as described above. Cleanup and sampling of former meth labs should be conducted under the supervision of a properly qualified person such as a Certified Industrial Hygienist. Decisions regarding the sampling plan can be made based on the prelim miary assessment information, chemicals used and duration of lab operation, the apparent extent and severity of contamination, and professional judgment. Variations of the cleanup and testing process may include: Sampling alone may be necessary when pre -cleaning samples indicate low levels or no contamination in some areas. In areas of moderate to heavy contamination, cleanup may be carried out without previous sampling if post -cleanup sampling will be conducted. In areas of obviously mild contamination, cleanup may be done without post -cleanup sampling, based on best judgment and adjacent sarapling results. 111 ip� I 11krAlkl4ifft J#E4K4 WIVA 1401141KIN400 After complete cleanup, small amounts of residual chemicals may remain. Post -cleanup sampling should be conducted after residual cleanup and/or the encapsulant has cured. This assessment should include sampling for meth residues on surfaces using a wipe sample. Wipe samples of hard surfaces will indicate levels of contamination on those surfaces and may also be the best indicator of the contamination in adjacent fabrics and other soft furnishings. The procedure for collecting a wipe sample is included as Attachment 1. This procedure is in accordance with the OSHA Technical Manual (http://www.osha.gov/dts/`osta/otnVotjn—ii/0tm—iL2.b�tml - 3). If the amalgam (P2P) method was used, testing should also include airborne mercury and lead, and surface sampling for lead. Risk-based exposure limits for lead and mercury are provided in Table 2. Bear in mind that the possibility of obtaining false positives for lead and mercury exists because these materials used to be commonly added to paints. Homes built before 1978 may test positive for lead and homes built before 1990 may test positive for mercury. In cases of moderate to heavy contamination, indoor air should be field screened, before and after cleaning, for volatile organic compounds (VOCs) with a photo ionization detector (PID), flame LEM Colorado Department of Public Health and Environment M82M Wfa1_CWWCMl9 Will alla Nalliplus, t1u: usu Ail Illuour ayr-(;�' Julls 111dj llot *c tri most practical way to evaluate the effectiveness of a cleanup.

The firial report should imunarize the work performed, present data collected during the post -cleanup assessment, and be signed by a Certified Industrial Hygienist, or other qualified envirompental professional. The local health department, or other oversight agency, may review the report and determine whether the property is suitable for re -occupancy. RE -OCCUPANCY OF STRUCTURES In order to deterinine acceptable risk-based concentrations for meth lab related chemicals, the Several other states have established cleanup standards specifically for the residue of meth. After communicating with some of these state health departments, it was learned that these levels are not health -based. The meth cleanup levels are based on what is believed to be conservative and protective, while at the same time achievable by clean-up contractors. Currently, there is not sufficient information available regarding the effects of long-tenn exposure to low concentrations of meth to adequately evaluate chronic minimum risk levels. Therefore, the Department is unable to provide a health -based exposure limit for meth at this time. As discussed previously, there are difficulties related to testing and evaluating the concentrations of meth related chemicals in indoor air. Therefore, the use of nieth testing to evaluate the effectiveness of cleanup may be more practical than the use of indoor air concentrations of other associated chemicals. In order to provide a practical measurement to determine the adequacy of cleanup, the Department W= Colorado Department of Public Health and Environment July 2003 evaluated the cleanup standards used by several other states. The cleanup levels for meth range from 5 Ug/ft2 to O5 U . Based upon limited information now available, the 0,5 Ug/ft2 standard appears to be the most conservative approach. In addition, the cleanup process necessary to reduce the levels of meth to 0.5 Ug/ft2 should also be capable of reducing the concentrations of other meth related chetnicals to acceptable levels. Testing for a limited suite of chemicals may be appropriate for "piece labs" that produce only pre -cursors or do limited production steps, since meth may not be present at these labs. ---------- with the Department's Hazardous Materials and Waste Management Division.

Relatively immobile contaminants (such as metals) that may have been released onto the ground surface will require considerably less subsurface data collection than a release involving relatively mobile contaminants (such as solvents). The subsurface characteristics will need to be defined to the degree necessary to provide a clear understanding of potential migration pathways for the purpose of defirting the extent of contamination.

Outdoor contamination may be dealt with, using one or more of the following measures: 1) waste removal, 2) site controls (eg., fencing), 3) drainage control, 4) monitoring, and 5) removal or treatment of contaminated soil or water (i.e., surface water or groundwater). The Hazardous Material and Waste Management Division has established soil cleanup levels for a limited number of chemical compounds associated with meth labs, as provided in Table 3.

They may be used dry, or wetted with water or solvent to enhance collection efficiency. The following procedure is recommended for collecting wipe samples: 1. If multiple samples are to be taken at the worksite, prepare a rough sketch of the area to be wipe sampled. 2. A new set of clean, impervious gloves should be used for each sample to avoid contamination of the filter by previous samples (and the possibility of false positives) and to prevent contact with the substance. 3. Withdraw the filter from the vial with your fingers or clean tweezers. If a damp wipe sample is desired, moisten the filter with distilled water (lead samples) or other solvent (methanol for meth samples) as recommended. 4. Depending on the purpose of the sample, it may be useful to detenm.me the concentration of contamination (eg., in micrograms of agent per area). For these samples, it is necessary to record the area of the surface wiped (e.g., 1111). This would normally not be necessary for samples taken to simply show the presence of the contaminant. 3MM28MMfl= 6. Start at the outside edge and progress toward the center of the surface area by wiping in concentric squares of decreasing size. 7. Without allowing the filter to come into contact with any other surface, fold the filter wi the exposed side in. If possible, use the same filter to repeat the sampling of the same arl then fold it over again. Place the filter in a sample vial, cap and number it, and note the number at the sample location on the sketch. Include notes with the sketch giving any further description of the sample. & At least one blank filter treated in the same fashion, but without wiping, should be submitted for each sampled area.

RfDs are obtained from the EPA Integrated Risk Information System (IRIS). InhIII alIIIIation RSIN "'f Mlle eferenc VIII The Inhalation Reference Concentration for chronic Concentration (RIC) noncarcinogenic health effects of a compound is analogous to the oral RfD and is likewise based on the assumption that thresholds exist for certain toxic effects. The RfC considers toxic effects for both the respiratory system (portal -of-entry) and for effects peripheral to the respiratory system (extrarespiratory effects). In general, the RfC is an estimate (with uncertainty spanning perhaps an order of magnitude) of a daily inhalation exposure of the human population (including sensitive subgroups) that is likely to be without an appreciable risk of harmful effects during a lifetime. RfCs are obtained from the EPA Integrated Risk Information System (IRIS).

Referenceiq s doses For chemicals th not have an IRIS RfC, a less desirable extrapolated to the option is to convert an IRIS oral reference doses (RfDs) for inhalation pathway inhalation exposure. This method converts dose from (mg/kg/day) to an exposure concentration (mg/m�) by multiplying the Rfl) of a chemical by 70 kg body weight and dividing by 20 m3/day. This method, however, has important limitations. ATSDR Minimal Risk The Agency for Toxic Substances and Disease Registry Level (MRL), Acute Minimal Risk Level (MRL) is an estimate of the daily human and Chronic exposure to a hazardous substance that is likely to be without appreciable risk of adverse noncancer health effects over a specified duration of exposure. Acute MRL values are for exposure up to 14 days, while Chronic MRL values are for exposure of one year to a lifetime. MRLs are intended to serve as screening levels. MRLs are not intended to define clean up or action levels. E NIOSH The National Institute for Occupational Safety and Health Recommended ` (NIOSH) Reclli ommended Exposure Limits (REL) are the Exposure Limits I! recommended maximum exposure level of a compound that a (REL) worker should be exposed to, in order to avoid adverse health effects. RELs are time -weighted average concentrations for up to a 10 -hour workday during a 40 -hour workweek. LOng-term Effects . .... ...... The Texas Natural Resource Conservation Commission Screening •Levels developed Long-term Effects Screening Levels (ESLs), by 1 (ESLs) dividing NIOSH RELs, by one thousand. This calculation was done to obtain long-term non -occupational (i.e. household) i referent concentrations. ESLs are used to evaluate the potential for effects to occur as a result of exposure to concentrations of constituents in the air. ESLs are based on data concerning health effects, odor nuisance potential, effects with re•ect to SP vegetation, and corrosion effects. They are not ambient air standards. If predicted or measured airborne levels of a constituent do not exceed the screening levels, adverse health or welfare effects would not be expected to result. If ambient levels of constituents in air exceed the screening levels, this does not necessarily indicate a health hazard exists. ....... . . . .
