Current through Register Vol. 47, No. 11, June 10, 2024

Section 6 CCR 1014-3-1-6.0 - Sampling and Analytical Procedures

6.1 General Requirements

6.1.1 No person other than a Consultant in good standing may conduct sampling under these regulations.

6.1.2 To prevent any real or potential conflicts of interest, a Consultant who is retained to conduct a screening level assessment, preliminary assessment, or clearance sampling at a given subject property must be independent of the Contractor who is retained to decontaminate the subject property.

6.1.3 The following sample collection procedures shall be followed for screening level sampling, preliminary assessment sampling and clearance sampling, except as provided in Section 6.8.2 of this Part 1.

6.1.3.1 Wipe sampling shall be used to determine the extent of methamphetamine contamination on all surfaces at all methamphetamine-affected properties, and at all properties that are undergoing a screening level assessment.

6.1.3.2. Wipe sampling shall be used to determine the extent of lead contamination on all surfaces at properties whenever the preliminary assessment indicates the phenyl-2-propanone (P2P) method of methamphetamine manufacture was used on the property.

6.1.3.3 Wipe sampling shall be used to determine the extent of iodine contamination whenever there is visible evidence of iodine staining on surfaces that will not be removed.

6.1.3.4 Vacuum sampling may, at the Consultant's discretion, be used instead of wipe sampling to determine the extent of methamphetamine, iodine or lead contamination on fabrics or textiles only.

6.1.3.5 Vapor sampling shall be used to determine the extent of mercury contamination whenever the preliminary assessment indicates the P2P method of methamphetamine manufacture was used on the property.

6.2Discrete Wipe Sample Collection Procedures. The following procedure shall be used for collecting discrete wipe samples:

6.2.1 Sample media shall consist of 2x2 inch wipes made of one of the following:

6.2.1.1 Cotton gauze material.

6.2.1.2 4-ply non-woven cotton/polyester blend.

6.2.1.3 Tightly knitted continuous filament polyester.

6.2.2 Delineate a 100 cm² area on the surface to be sampled, either by attaching a physical template to the surface (being careful not to touch the area within the template), or by an equivalently reliable and accurate method. The area within the template (i.e., the sample area) shall be 100 cm². Physical templates may not be re-used.

6.2.3 Prepare a rough sketch of the area(s) to be sampled and indicate sample location(s).

6.2.4 Wet the sample media with isopropanol to enhance collection efficiency.

6.2.5 Use a new set of clean, non-powdered impervious gloves for each sample to avoid contamination of the sample media by previous samples and to prevent contact with the substance.

6.2.6 Press the sample media down firmly, but not excessively, with the fingers, being careful not to touch the sample surface with the thumb. Blot rough surfaces uniformly instead of wiping. Wipe smooth surfaces as described in the next section below.

6.2.7 Wipe the surface using one of the following methods:

6.2.7.1 Square method: Start at the outside edge and progress toward the center of the surface area by wiping in concentric squares of decreasing size.

6.2.7.2 "S" method: Wipe horizontally from side-to-side in an overlapping "S"-like pattern as necessary to completely cover the entire wipe area.

6.2.8 Without allowing the sample media to come into contact with any other surface, fold the sample media with the sampled side in.

6.2.9 Use the same sample media to repeat the sampling of the same area using the same method. If using the "S" method, the second pass shall be sampled by wiping with overlapping "S"-like motions in a top-to-bottom direction.

6.2.10 Fold sampled side in. Using the same sample media, sample the same area a third time. The third pass shall be sampled by wiping using the method not previously used (i.e., use the square method if the "S" method was originally used).

6.2.11 Fold the sample media over again so that the sampled side is folded in. Place the sample media in a sample container, cap and number it, and note the number at the sample location on the sketch. Remove and discard impervious gloves. Include notes with the sketch giving any further description of the sample, including sample name and time of collection. Photograph each sample location.

6.2.12 Submit at least one field blank, prepared and handled in the same fashion but without wiping, for every 10 samples collected, according to the following:

6.2.12.1 To collect a field blank, remove a wipe from the wrapper with a new glove, shake the wipe open, refold in the same manner as during the sampling procedure, and then insert the wipe into the sample container.

6.2.12.2 Repeat this procedure for multiple aliquots when collecting a composite field blank.

6.2.12.3 For projects with fewer than 10 samples collected, the last sample collected shall be the field blank.

6.2.12.4 For projects with greater than 10 samples collected, sample 11 shall be a field blank, every 10th subsequent sample shall be a field blank, and the last sample of any sample group with fewer than 10 samples shall be a field blank.

6.2.12.5 Field blanks shall be representative of the majority of samples collected for every sample group (i.e., discrete or composite).

6.2.13 Follow sample handling procedures as specified by the analytical method listed in Section 6.12 of this Part 1.

6.2.14 Maintain a Chain-of-Custody Record covering the time of sample collection through final disposition. Document sample(s) collected from a single methamphetamine-affected property on one Chain-of-Custody Record. Every transfer of custody shall be noted and signed for and a copy of the record shall be kept by each individual who has signed it. Samples shall be sealed, labeled, and secured. All samples collected shall be transported directly to the laboratory. Shipping samples overnight is considered direct transport, and the shipping label shall be considered part of the Chain-of-Custody Record. Retain all sample documents for the project record and include them in the project reports. At a minimum, the Chain-of-Custody Record shall include the following:

6.2.14.2 subject property address;

6.2.14.3 sampler name and contact information;

6.2.14.4 sample identification number;

6.2.14.5 sample area;

6.2.14.6 number of sample aliquots;

6.2.14.7 number of containers for each sample;

6.2.14.8 sample collection time and date;

6.2.14.9 sample matrix;

6.2.14.10 requested analysis;

6.2.14.11 sample preservatives, if applicable; and

6.2.14.12 signature and date for each person relinquishing or receiving sample custody.

6.2.15 Painted-over surfaces. Estimate the concentration of methamphetamine present below a painted-over surface (as defined in Section 2 of this Part 1) by one of the following methods:

6.2.15.2 collect wipe samples from similar surfaces within the same room that were not painted after contamination was introduced, or

6.2.15.3 sample the painted over surface as set forth in 6.2.1- 6.2.14, but use methanol instead of isopropanol as the wetting agent for the sampling media to acquire a representative sample from beneath the painted-over surface.

6.3Composite Wipe Sample Collection Procedures. When collecting composite samples, use the procedure outlined in Section 6.2 above for discrete samples for the collection of each aliquot comprising the composite sample, with the following exceptions:

6.3.1 A single pair of gloves may be used to collect each aliquot that will be part of a single composite sample. Use a new pair of gloves for each set of composite samples.

6.3.2 Use a separate piece of sample media for each aliquot.

6.3.3 Place the sample media from all individual aliquots that make up a composite sample in one sample container.

6.3.4 Combine no more than 4 aliquots in a single composite sample.

6.3.5 All aliquots in a single composite sample collected from personal property must be collected from similar material (non-porous, porous other than textiles/fabrics, and textiles/fabrics).

6.3.6 Collect all individual aliquots from 100 cm² sampling areas.

6.4Vacuum Sample collection procedures. At the Consultant's discretion, vacuum sampling may be used to determine the extent of contamination on fabrics and textiles, including carpeting, drapery, upholstery, clothing, and other fabric goods. Vacuum samples shall be collected in accordance with procedures for sample collection described in Section 9 of the ASTM International Method D5756-02, Standard Test Method for Microvacuum Sampling and Indirect Analysis of Dust by Transmission Electron Microscopy for Asbestos Mass Concentration as incorporated in Section 9 of this Part 1.

6.5Vapor Sample collection procedures. If the preliminary assessment indicates the phenyl-2-propanone (P2P) method of methamphetamine manufacturing was used, vapor samples for mercury shall be collected in accordance with the procedures for sample collection described in NIOSH Method 6009 as incorporated in Section 9 of this Part 1.

6.6OWTS Sampling. If the subject property has an OWTS, the Consultant shall conduct field screening, and if necessary sample collection from the OWTS to confirm or deny the presence of methamphetamine lab waste, and to ensure proper disposal of any methamphetamine lab waste identified.

6.6.1 Field Screening. Field screening of septic tanks shall be conducted if there is evidence that methamphetamine lab wastes may have been disposed of into an OWTS. Evidence of methamphetamine lab wastes disposal into an OWTS includes, but is not limited to, the following:

6.6.1.1 witness statements;

6.6.1.2 stained or etched sinks, bathtubs, toilets;

6.6.1.3 chemical odors coming from the OWTS plumbing or tank;

6.6.1.4 visual observations of unusual conditions within the septic tank ("dead tank"); or

6.6.1.5 stressed or dead vegetation in a drain field.

6.6.2 Initial field screening shall consist of the following:

6.6.2.1 Monitoring the septic tank for volatile organic compounds (VOCs) using a photo ionization detector (PID), flame ionization detector (FID), or other instrument capable of measuring VOCs with a demonstrated accuracy of plus or minus 25%.

6.6.2.2 Testing the pH of liquid in the septic tank using pH paper or a pH meter.

6.6.2.3 Additional field screening may be conducted, at the discretion of the Consultant, to further investigate the possible presence of methamphetamine lab waste.

6.6.3Sample Collection. If field screening indicates that the OWTS has not been impacted by methamphetamine lab wastes, the Consultant may, at his or her discretion, presume the OWTS to be uncontaminated, and no further sampling is required. If field screening indicates that the OWTS has been impacted by methamphetamine lab wastes, the Consultant shall collect samples from the septic tank to determine if the liquids in the tank contain a hazardous waste. Samples shall be collected according to the requirements of the analytical method being used and the following protocol:

6.6.3.1 Prior to sampling, determine whether the tank consists of one or two chambers through records review, visual inspection of the tank or by sufficiently excavating the septic tank.

6.6.3.2 Samples from single chamber tanks shall be collected from the baffle on the outlet end of the tank.

6.6.3.3 Samples from dual chamber tanks shall be collected from the baffle on the outlet end of chamber one.

6.6.3.4 Samples must be representative of the wastes found in the septic tank. Sampling procedures may include the use of drum thieves, sludge judges or equivalent equipment. The instructions for the correct usage of the sampling device shall be followed.

6.6.3.5 Remove access cover from the first (or only) chamber and locate outlet baffle.

6.6.3.6 Move any floating surface matter away from the insertion point of the sampling device. Do not collect any matter in the sampling device.

6.6.3.7 Insert the sampling device into the tank, lowering it until it hits the bottom.

6.6.3.8 Trap the sample inside the sampling device.

6.6.3.9 Remove the sampling device and fill the laboratory supplied sample containers. The specific volume and type of sample container will be determined based on the type of analysis desired. For VOC analysis, two 40ml vials shall be filled, leaving no headspace.

6.6.3.10 Replace access cover at the completion of sample collection.

6.6.3.11 Samples may be collected in laboratory preserved bottles, or in unpreserved bottles. If the samples are collected in unpreserved bottles, the laboratory must be notified that the samples are unpreserved.

6.6.3.12 Place sample containers in a cooler with enough ice or ice packs to maintain a temperature of 4° C.

6.6.3.13 Maintain a Chain-of-Custody Record from the time of sample collection until final disposition. Every transfer of custody shall be noted and signed for and a copy of the record shall be kept by each individual who has signed it. Samples shall be sealed, labeled, and secured. All samples collected shall be transported directly to the laboratory. Shipping samples overnight is considered direct transport, and the shipping label shall be considered part of the Chain-of-Custody Record. All sample documents shall be retained for the project record and included in project reports.

6.6.4Waste Characterization. The contents of septic tanks that contain waste from methamphetamine labs are solid wastes. Prior to disposal, a hazardous waste determination must be made in accordance with 6 CCR 1007-3 Section 261.20 through 261.24 . The following analyses, as incorporated in Section 9 of this Part 1, shall be conducted to determine if an OWTS has been impacted by methamphetamine lab wastes, and if the septic tank contains a characteristic hazardous waste:

6.6.4.1 VOCs using Method 8260B in "Test Methods for the Evaluation of Solid Waste, Physical/Chemical Methods," EPA Publication SW-846.

6.6.4.2 Ignitability/flash point by a Pensky-Martens Closed Cup Tester, using the test method specified in ASTM Standard D-93-79 or D-93-80 (or Method 1010A in EPA SW-846), or Setaflash Closed Cup Tester, using the test method specified in ASTM standard D-3278-78 (or Method 1020B in EPA SW-846).

6.6.4.3 Corrosivity as determined by Method 9040C or Method 1110A in EPA Publication SW-846.

6.7 Screening level sampling protocols for buildings.

6.7.1 For screening assessments performed in connection with a proposed transaction for the purchase of a single-family dwelling, or the purchase of a single unit of a multi-unit building (e.g., a condominium):

6.7.1.1 a minimum of two (2) 4-aliquot composite samples must be collected, with at least one aliquot being collected from each room. At least one composite sample must include an aliquot from the cold air return of a heating system, if it is a forced air system.

6.7.1.2 All exhaust fans (including, but not limited to, kitchen, bathrooms, attic vent fans, or whole house exhaust fans) must also be sampled. Exhaust fan samples shall be collected from inside the fan compartment, the fan blade, or the back side of the fan grill. A separate surface sample does not need to be collected from any room from which a fan or ventilation system sample is collected.

6.7.1.3 For single family dwellings, at least one aliquot must be taken from each room of all outbuildings.

6.7.1.4 In the case of single family dwellings, if there are any additional dwellings on the subject property (such as a living space over a garage, mother-in-law apartment, etc.), the additional dwelling(s) shall be sampled as provided in Sections 6.7.1.1 and 6.7.1.2 of this Part 1.

6.7.2 For screening assessments performed in connection with a proposed transaction for the purchase of a multi-unit building where no units exhibit signs of being an illegal drug laboratory, at least ten (10) percent of such units shall be evaluated through the collection of at least one 4-aliquot composite sample per unit, with at least one aliquot being drawn from each room in the unit. At least one composite sample must include an aliquot from the cold air return of a heating system, if it is a forced air system. All exhaust fans in sampled units must also be sampled.

6.7.2.1 Collect at least one aliquot per room of each outbuilding.

6.7.3 Samples collected by the seller's Consultant, for the purpose of disputing samples collected by the buyer's Consultant, shall not be collected from the exact location as the previous sample. Alternate sample locations, determined by the Consultant to be representative, shall be used if there is no surface area remaining in the original sample location that has not already been sampled.

6.8 Assessment level sampling protocols for buildings and personal property.

6.8.1 Except as provided in Section 6.8.2 below, the Consultant shall conduct sampling for methamphetamine that meets the clearance level sampling protocols of Section 6.9 in all rooms of a methamphetamine-affected property as part of the preliminary assessment.

6.8.2 The Consultant may determine that some (or all) rooms, attics, crawls spaces, and forced air ventilation systems should be deemed to be contaminated based on data other than assessment sampling. Personal property located in rooms that are deemed to be contaminated is also deemed to be contaminated. Rooms that are deemed to be contaminated do not need to be sampled as part of the preliminary assessment, nor do their contents. However, the Consultant may choose to conduct additional sampling of those rooms or their contents to inform decontamination decisions.

6.9Clearance level sampling protocols for buildings and personal property. The Consultant shall conduct clearance level sampling of any subject property that meets the definition of a methamphetamine-affected property, or that is suspected of being a methamphetamine-affected property as provided in Sections 3.2 , 3.3 or 3.4 of this Part 1, to verify that cleanup standards have been met. If the subject property is a single family dwelling, the Consultant shall conduct clearance sampling of all structures on the property. If the subject property is a unit in a multi-unit building that has exclusive access to any auxiliary portion of the multi-unit property (such as a storage room or garage), the Consultant shall conduct clearance sampling of the unit and all such auxiliary structures. Samples shall be collected according to the following criteria:

6.9.1 Except as provided in Section 6.9.1.1, at least 400 cm² of surface area shall be sampled from every room, attic, and crawl space.

6.9.1.1 For buildings and structures that have had their internal walls removed during decontamination, post decontamination sampling shall be conducted in accordance with Section 6.9.2 and Section 6.9.3.

6.9.2 At least 800 cm² of total surface area must be sampled for any single methamphetamine-affected property.

6.9.3 For rooms greater than 500 ft² of floor space an additional 100 cm² of surface area shall be sampled for each additional 500 ft² or fraction thereof.

6.9.4 For buildings and structures that have forced air ventilation systems, at least 400 cm² of surface area of the ventilation system shall be sampled, unless the entire ventilation system is removed. Samples shall be collected from accessible areas within the heat exchanger unit, inside the cold air return system, from inside the supply air system, and from one other location selected at the Consultant's discretion. The Consultant will visually inspect accessible portions of the ventilation system and review photo documentation to verify that the system has been cleaned and is free of debris.

6.9.5 For buildings and structures with non-ducted heating or cooling systems that circulate indoor air, one discrete sample shall be collected from each heating or cooling unit.

6.9.6 Composite samples may be used for clearance sampling of rooms, attics, crawl spaces, and personal property, provided all aliquots comprising a composite sample come from the same room, attic, or crawl space.

6.9.7 The interior of major appliances (microwaves, refrigerators, freezers, ovens, and dryers) must be sampled using discrete samples. The exterior of major appliances may be sampled using composite samples.

6.9.8 Items in a closet that is less than 75 ft.² may be sampled separately from items in the adjoining room (e. g., clothing from a bedroom closet may be sampled separately from textiles in the bedroom).

6.9.9 A composite sample of personal property is considered representative of contaminant levels on all personal property of that type material (non-porous, porous other than textiles/fabrics, or textiles/fabrics) within the same room. Should analysis of composite samples from multiple items indicate methamphetamine levels in excess of the cleanup standard, all items from which the composite sample was comprised, and all items of that type material within the same room will be considered to be in excess of the cleanup standard, unless a discrete sample of an individual item demonstrates that the cleanup standard has been met on that item.

6.9.10 For structures that have no rooms, the Consultant shall sample at least 100 cm² of surface area for every 500 ft² of floor space.

6.9.11 Locations of clearance samples shall be based on information gathered during the preliminary assessment. Samples shall be collected from surfaces that have a reasonable potential to contribute to human exposure, including:

6.9.11.1 Areas expected to have the highest levels of contamination, such as cooking areas, chemical storage areas, and waste disposal areas.

6.9.11.2 Areas where contamination may have migrated, such as adjacent rooms or units, common areas, shared attics, shared crawl spaces, shared ventilation systems, and units connected to the contaminated unit by such attics, crawl spaces, or ventilation systems.

6.9.11.3 Personal property that will not be disposed of, except that hard non-porous household goods including ceramics, hard plastics, metals, and glass that show no signs of having been used during the methamphetamine cooking process (e.g., are not etched, stained, or emitting odors) do not require clearance sampling if they are washed at least two times using a detergent-water solution. As used in this section, the term "household goods" excludes major appliances such as ranges, cooktops, ovens, microwaves, and refrigerators.

6.9.11.4 Clothing and linens, except that no sampling is required for:

6.9.11.4.1 clothing or linens that will immediately be disposed of at a solid waste landfill; or

6.9.11.4.2 clothing or linens that are not obviously contaminated, provided such items are managed in accordance with 5.11.3.

6.10Clearance level sampling protocols for vehicles.

6.10.1 The Consultant shall sample a minimum of 400 cm² of the interior surface of the vehicle.

6.10.2 The Consultant shall sample an additional 100 cm² for every 50 ft² of floor space for any large vehicle, such as a recreational vehicle, motor home, trailer, or camper.

6.10.3 Composite sampling of vehicles is allowed, provided that all aliquots making up an individual composite are taken from the same vehicle.

6.11Surface Soil Sampling.

6.11.1 The following procedures shall be followed when conditions indicate the potential for soil contamination:

6.11.1.1 Samples for volatile organic compound (VOC) and semi-volatile organic compound (SVOC) analysis must be collected as discrete samples.

6.11.1.2 Samples for methamphetamine and non-volatile compounds may either be collected as discrete samples or composite samples.

6.11.2 Discrete surface soil samples shall be collected as follows:

6.11.2.1 At each sampling location, clear an area approximately 12 inches in diameter of surface vegetation and debris.

6.11.2.2 Use a decontaminated stainless steel spoon to collect the surface soil to a depth of six inches (i.e., 0-6 inch sample). A decontaminated stainless steel pick may be used as needed to loosen the soil. To the extent possible, eliminate gravel-sized or larger particles and debris based on visual observation. Be sure to collect sufficient sample volume to meet analytical requirements.

6.11.2.3 Use laboratory supplied or clean unused sample containers. If VOC and SVOC analyses are to be performed, immediately fill the VOC and SVOC sample containers fully to eliminate head space. Tightly seal the containers with the appropriate lids. Follow sample handling procedures as specified by the analytical method listed in Section 6.12 of this Part 1.

6.11.2.4 A Chain-of-Custody Record shall be maintained from the time of sample collection until final disposition. Sample(s) collected from a single methamphetamine-affected property shall be documented on one Chain-of-Custody Record. Every transfer of custody shall be noted and signed for and a copy of the record shall be kept by each individual who has signed it. Samples shall be sealed, labeled, and secured. All samples collected shall be transported directly to the laboratory while maintaining the required temperature controls as specified by the analytical method. Shipping samples overnight is considered direct transport, and the shipping label shall be considered part of the Chain-of-Custody Record. All sample documents shall be retained for the project record and included in the project reports.

6.11.2.5 Decontaminate the sampling equipment prior to collecting additional samples.

6.11.3 Each composite surface soil sample shall be collected as follows:

6.11.3.1 Composite sampling shall consist of the collection of a 5-aliquot or 10-aliquot composite soil sample collected from a grid with a maximum surface area of 10,000 ft². Aliquot locations shall be evenly spaced throughout the entire grid.

6.11.3.2 Prior to sampling, calculate the volume of sample material to be collected for each aliquot to ensure that the necessary amount of composite sample will be obtained. Required sample volumes shall be those specified by the analytical method listed in Section 6.12 of this Part 1. For a given composite sample, the volume of each aliquot must be the same, and must equal 1/n of the required composite sample volume, where n equals the number of aliquot samples making up the composite sample.

6.11.3.3 At each aliquot sample location, clear an area approximately 12 inches in diameter of surface vegetation and debris.

6.11.3.4 Use a decontaminated stainless steel spoon to collect surface soil to a depth of six inches. A decontaminated stainless steel pick may be used as needed to loosen the soil. To the extent possible, eliminate gravel-size or larger particles and debris based on visual observation. Be sure to collect a sufficient volume of aliquot sample. The volume of aliquot collected at each location must be the same.

6.11.3.5 Place the aliquot into a decontaminated stainless steel mixing bowl.

6.11.3.6 Repeat Steps 3 through 5 of this Section 6.11.3 at each aliquot sample location for a given composite sample, adding each successive aliquot sample to the mixing bowl.

6.11.3.7 Thoroughly mix the sample material in the stainless steel bowl using a decontaminated stainless steel spoon. To homogenize, divide the sample into four quarters and mix each quarter, then combine the four quarters and mix the entire sample. Place the mixture into appropriate laboratory-supplied or clean unused sample containers. Tightly seal the containers with the appropriate lids. Follow sample handling procedures as specified by the appropriate analytical method listed in Section 6.12 of this Part 1.

6.11.3.8 A Chain-of-Custody Record shall be maintained from the time of sample collection until final disposition. Sample(s) collected from a single methamphetamine-affected property shall be documented on one Chain-of-Custody Record. Every transfer of custody shall be noted and signed for and a copy of the record shall be kept by each individual who has signed it. Samples shall be sealed, labeled, and secured. All samples collected shall be transported directly to the laboratory. Shipping samples overnight is considered direct transport, and the shipping label shall be considered part of the Chain-of-Custody Record. All sample documents shall be retained for the project record and included in the project reports.

6.11.3.9 Decontaminate the sampling equipment prior to collecting additional samples.

6.11.4 If surface soil sampling indicates that soil has been impacted by methamphetamine lab waste, additional investigation and remediation shall be conducted under an approved plan in accordance with the Colorado Hazardous Waste Regulations (6 CCR 1007-3) or the Colorado Solid Waste Regulations (6 CCR 1007-2).

6.12Analytical Methods. The following analytical methods, as incorporated in Section 9 of this Part 1, shall be used, as applicable, to determine the concentrations of chemicals in samples collected during screening level assessments, preliminary assessments, or clearance sampling. These incorporated materials are more fully identified, including dates of publication, in the list immediately following Section 9 of this Part 1. Sample handling, including labeling, preservation, documentation, and chain-of-custody, shall be conducted consistent with the requirements of the analytical method being used.
