5.1 Sediment toxicity evaluations are a critical component of environmental quality and ecosystem impact assessments, and are used to meet a variety of research and regulatory objectives. The manner in which the sediments are collected, stored, characterized, and manipulated can influence the results of any sediment quality or process evaluation greatly. Addressing these variables in a systematic and uniform manner will aid the interpretations of sediment toxicity or bioaccumulation results and may allow comparisons between studies.5.2 Sediment quality assessment is an important component of water quality protection. Sediment assessments commonly include physicochemical characterization, toxicity tests or bioaccumulation tests, as well as benthic community analyses. The use of consistent sediment collection, manipulation, and storage methods will help provide high quality samples with which accurate data can be obtained for the national inventory and for other programs to prevent, remediate, and manage contaminated sediment.5.3 It is now widely known that the methods used in sample collection, transport, handling, storage, and manipulation of sediments and interstitial waters can influence the physicochemical properties and the results of chemical, toxicity, and bioaccumulation analyses. Addressing these variables in an appropriate and systematic manner will provide more accurate sediment quality data and facilitate comparisons among sediment studies.5.4 This standard provides current information and recommendations for collecting and handling sediments for physicochemical characterization and biological testing, using procedures that are most likely to maintain in situ conditions, most accurately represent the sediment in question, or satisfy particular needs, to help generate consistent, high quality data collection.5.5 This standard is intended to provide technical support to those who design or perform sediment quality studies under a variety of regulatory and non-regulatory programs. Information is provided concerning general sampling design considerations, field and laboratory facilities needed, safety, sampling equipment, sample storage and transport procedures, and sample manipulation issues common to chemical or toxicological analyses. Information contained in this standard reflects the knowledge and experience of several internationally-known sources including the Puget Sound Estuary Program (PSEP), Washington State Department of Ecology (WDE), United States Environmental Protection Agency (USEPA), US Army Corps of Engineers (USACE), National Oceanic and Atmospheric Administration (NOAA), and Environment Canada. This standard attempts to present a coherent set of recommendations on field sampling techniques and sediment or interstitial water sample processing based on the above sources, as well as extensive information in the peer-reviewed literature.5.6 As the scope of this standard is broad, it is impossible to adequately present detailed information on every aspect of sediment sampling and processing for all situations. Nor is such detailed guidance warranted because much of this information (for example, how to operate a particular sampling device or how to use a Geographical Positioning System (GPS) device) already exists in other published materials referenced in this standard.5.7 Given the above constraints, this standard: (1) presents a discussion of activities involved in sediment sampling and sample processing; (2) alerts the user to important issues that should be considered within each activity; and (3) gives recommendations on how to best address the issues raised such that appropriate samples are collected and analyzed. An attempt is made to alert the user to different considerations pertaining to sampling and sample processing depending on the objectives of the study (for example, remediation, dredged material evaluations or status and trends monitoring).5.8 The organization of this standard reflects the desire to give field personnel and managers a useful tool for choosing appropriate sampling locations, characterize those locations, collect and store samples, and manipulate those samples for analyses. Each section of this standard is written so that the reader can obtain information on only one activity or set of activities (for example, subsampling or sample processing), if desired, without necessarily reading the entire standard. Many sections are cross-referenced so that the reader is alerted to relevant issues that might be covered elsewhere in the standard. This is particularly important for certain chemical or toxicological applications in which appropriate sample processing or laboratory procedures are associated with specific field sampling procedures.5.9 The methods contained in this standard are widely applicable to any entity wishing to collect consistent, high quality sediment data. This standard does not provide guidance on how to implement any specific regulatory requirement, or design a particular sediment quality assessment, but rather it is a compilation of technical methods on how to best collect environmental samples that most appropriately address common sampling objectives.5.10 The information presented in this standard should not be viewed as the final statement on all the recommended procedures. Many of the topics addressed in this standard (for example, sediment holding time, formulated sediment composition, interstitial water collection and processing) are the subject of ongoing research. As data from sediment monitoring and research becomes available in the future, this standard will be updated as necessary.1.1 This guide covers procedures for obtaining, storing, characterizing, and manipulating marine, estuarine, and freshwater sediments, for use in laboratory sediment toxicity evaluations and describes samplers that can be used to collect sediment and benthic invertebrates (Annex A1). This standard is not meant to provide detailed guidance for all aspects of sediment assessments, such as chemical analyses or monitoring, geophysical characterization, or extractable phase and fractionation analyses. However, some of this information might have applications for some of these activities. A variety of methods are reviewed in this guide. A statement on the consensus approach then follows this review of the methods. This consensus approach has been included in order to foster consistency among studies. It is anticipated that recommended methods and this guide will be updated routinely to reflect progress in our understanding of sediments and how to best study them. This version of the standard is based primarily on a document developed by USEPA (2001 (1))2 and by Environment Canada (1994 (2)) as well as an earlier version of this standard.1.2 Protecting sediment quality is an important part of restoring and maintaining the biological integrity of our natural resources as well as protecting aquatic life, wildlife, and human health. Sediment is an integral component of aquatic ecosystems, providing habitat, feeding, spawning, and rearing areas for many aquatic organisms (MacDonald and Ingersoll 2002 a, b (3)(4)). Sediment also serves as a reservoir for contaminants in sediment and therefore a potential source of contaminants to the water column, organisms, and ultimately human consumers of those organisms. These contaminants can arise from a number of sources, including municipal and industrial discharges, urban and agricultural runoff, atmospheric deposition, and port operations.1.3 Contaminated sediment can cause lethal and sublethal effects in benthic (sediment-dwelling) and other sediment-associated organisms. In addition, natural and human disturbances can release contaminants to the overlying water, where pelagic (water column) organisms can be exposed. Sediment-associated contaminants can reduce or eliminate species of recreational, commercial, or ecological importance, either through direct effects or by affecting the food supply that sustainable populations require. Furthermore, some contaminants in sediment can bioaccumulate through the food chain and pose health risks to wildlife and human consumers even when sediment-dwelling organisms are not themselves impacted (Test Method E1706).1.4 There are several regulatory guidance documents concerned with sediment collection and characterization procedures that might be important for individuals performing federal or state agency-related work. Discussion of some of the principles and current thoughts on these approaches can be found in Dickson, et al. Ingersoll et al. (1997 (5)), and Wenning and Ingersoll (2002 (6)).1.5 This guide is arranged as follows:  Section  1Referenced Documents  2Terminology  3Summary of Guide  4  5Interferences  6Apparatus  7Safety Hazards  8Sediment Monitoring and Assessment Plans  9Collection of Whole Sediment Samples 10Field Sample Processing, Transport, and Storage of Sediments 11Sample Manipulations 12Collection of Interstitial Water 13Physico-chemical Characterization of Sediment Samples 14Quality Assurance 15Report 16Keywords 17Description of Samplers Used to Collect Sediment or Benthic Invertebrates Annex A11.6 Field-collected sediments might contain potentially toxic materials and should thus be treated with caution to minimize occupational exposure to workers. Worker safety must also be considered when working with spiked sediments containing various organic, inorganic, or radiolabeled contaminants, or some combination thereof. Careful consideration should be given to those chemicals that might biodegrade, volatilize, oxidize, or photolyze during the exposure.1.7 The values stated in either SI or inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.Specific hazards statements are given in Section 8.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 U.S. Department of Defense and U.S. Department of Justice standards require ballistic limit determination for assessing the performance of ballistic-resistant body armor.5.2 This test method may be used by private-sector and government laboratories, manufacturers, research and development organizations, and others assessing the ballistic resistance of body armor or performing research and development of new materials.5.3 It is intended that this test method be referenced by other standards, specifications, and test methods.1.1 This test method addresses the collection of ballistic limit data for ballistic-resistant torso body armor and shoot packs.1.2 This test method is intended for testing of soft body armor, hard armor plates, and shoot packs. This test method does not apply to ballistic helmets.1.3 This test method describes procedures for collecting data and does not specify computation or performance criteria for the ballistic limit. Instructions for computation and performance criteria are specified in other standards and specifications.1.4 Several commonly used test item mounting procedures and ballistic limit procedures are included in this test method; certifiers, purchasers, and other users will specify the procedures to be used.1.5 This test method does not address conditioning of test items.1.6 It is anticipated that this test method will be referenced by certifiers, purchasers, or other users to meet their specific needs.1.6.1 Certifier, purchasers, and other users will specify and describe the ballistic test threats to be used. Within this test method, the reference will be called the “test threats document.”1.6.2 Certifiers, purchasers, and other users will provide specific instructions for the determination of complete penetrations or partial penetrations.1.6.3 In this test method, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) that require the use of this test method. Certifiers, purchasers, and other users are responsible for the “other standards and specifications” and for specifying any requirements that supersede those of this test method.1.7 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.7.1 The user of this standard will identify the system of units to be used, and it is critical to ensure that any cross-referenced standards maintain consistency of units between standards.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This practice may be used to collect dust from carpeted or bare floor surfaces for gravimetric or chemical analysis. The collected sample is substantially unmodified by the sampling procedure.5.2 This practice provides for a reproducible dust removal rate from level loop and plush carpets, as well as bare floors. It has the ability to achieve relatively constant removal efficiency at different loadings of floor dust.5.3 This practice also provides for the efficient capture of semivolatile organic chemicals associated with the dust. The test system can be fitted with special canisters downstream of the cyclone for the capture of specific semivolatile organic chemicals that may volatilize from the dust particles during collection.5.4 This practice does not describe procedures for evaluation of the safety of floor surfaces or the potential human exposure to floor dust. It is the user's responsibility to evaluate the data collected by this practice and make such determinations in the light of other available information.5.5 This practice provides per-event dust chemical concentration and chemical loading. Advantages and trade-offs of different sampling approaches have been discussed (7).5.6 This practice uses a removable, cleanable dropout jar that facilitates per-event sampling. Other per-event vacuum attachments are commercially available. These are not directly comparable with composite sampling done using whole vacuum cleaner bags.1.1 This practice covers a procedure for the collection of a sample of dust from carpets and bare floors that can be analyzed for inorganic metals such as lead and organic compounds such as pesticides and other semi-volatile organic compounds (SVOCs).1.2 This practice is applicable to a variety of carpeted and bare floor surfaces. It has been tested for level loop and plush pile carpets and bare wood floors, specifically. This practice is not applicable to elevated, non-floor surfaces.1.3 This practice is not intended for the collection and evaluation of dust for the presence of asbestos fibers.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This practice describes use of a sampling device, the High-Volume Small Surface Sampler (HVS3). Other event-based sampling devices that use commercially available vacuum attachments are not in scope. Composite sampling using whole vacuum cleaner bags is not in scope. Other approaches for floor or non-floor surface sampling (Practices D6966, D6661, D7144) are not within the scope.1.6 This practice only applies to the HVS3. Other dust sampling methods may or may not be directly comparable. Method evaluation for other dust sampling approaches is encouraged. This could be done by comparison with methods outlined in this standard practice for HVS3 or through independent evaluation using field spikes and certified reference materials.1.7 This practice provides information on dust loading, chemical dust concentration, and chemical dust loading. Information on the type of floor, the floor surface area sampled, and amount of dust collected is required (see Fig. 2). Cleaning the vacuum attachments in between sampling events is also required (see Section 13).1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Although many technical papers address topics important to efficient and accurate sampling investigations (DQOs, study design, QA/QC, data assessment; see Guides D4687, D5730, D6009, D6051, and Practice D5283), the selection and use of appropriate sampling equipment is assumed or omitted.5.2 The choice of sampling equipment can be crucial to the task of collecting a sample appropriate for the intended use.5.3 When a sample is collected, all sources of potential bias should be considered, not only in the selection and use of the sampling device, but also in the interpretation and use of the data generated. Some major considerations in the selection of sampling equipment for the collection of a sample are listed below:5.3.1 The ability to access and extract from every relevant location in the target population,5.3.2 The ability to collect a sufficient mass of sample such that the distribution of particle sizes in the population are represented, and5.3.3 The ability to collect a sample without the addition or loss of constituents of interest.5.4 The characteristics discussed in 5.3 are particularly important in investigations when the target population is heterogeneous, such as when particle sizes vary, liquids are present in distinct phases, a gaseous phase exists, or materials from different sources are present in the population. The consideration of these characteristics during the equipment selection process will enable the data user to make appropriate statistical inferences about the target population based on the sampling results.5.5 If samples are to be collected for the determination of per- and poly-fluorinated alkyl substances (PFAS), all sampling equipment should be made of fluorine-free materials. Other considerations for PFAS sampling may exist but are beyond the scope of this standard.1.1 This guide covers criteria which should be considered when selecting sampling equipment for collecting environmental and waste samples for waste management activities. This guide includes a list of equipment that is used and is readily available. Many specialized sampling devices are not specifically included in this guide. However, the factors that should be weighed when choosing any piece of equipment are covered and remain the same for the selection of any piece of equipment. Sampling equipment described in this guide includes automatic samplers, pumps, bailers, tubes, scoops, spoons, shovels, dredges, coring, augering, passive, and vapor sampling devices. The selection of sampling locations is outside the scope of this guide.1.1.1 Table 1 lists selected equipment and its applicability to sampling matrices, including water (surface and ground), sediments, soils, liquids, multi-layered liquids, mixed solid-liquid phases, and consolidated and unconsolidated solids. The guide does not specifically address the collection of samples of any suspended materials from flowing rivers or streams. Refer to Guide D4411 for more information.1.2 Table 2 presents the same list of equipment and its applicability for use based on compatibility of sample and equipment; volume of the sample required; physical requirements such as power, size, and weight; ease of operation and decontamination; and whether it is reusable or disposable.1.3 Table 3 provides the basis for selection of suitable equipment by the use of an index.1.4 Lists of advantages and disadvantages of selected sampling devices and line drawings and narratives describing the operation of sampling devices are also provided.1.5 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.1.6 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This practice is intended for the collection of settled dust samples for the subsequent measurement of beryllium and compounds. The practice is meant for use in the collection of settled dust samples that are of interest in clearance, hazard evaluation, risk assessment, and other purposes.5.2 This practice is intended solely for the collection of settled dust samples from hard, relatively smooth nonporous surfaces that may be compromised by water or other wetting agents and that are therefore not suitable for wet wipe sampling using Practice D6966 or micro-vacuum sampling using Practice D7144. Use of this practice for any purpose other than the intended purpose is discouraged due to the limited collection efficiency and high variability of dry wipe sampling as compared to wetted wipe or micro-vacuum sampling.35.3 This practice is less effective for collecting settled dust samples from surfaces with substantial texture such as rough concrete, brickwork, textured ceilings, and soft fibrous surfaces such as upholstery and carpeting. Micro-vacuum sampling using Practice D7144 may be more suitable for these surfaces.1.1 This practice covers the collection of settled dust containing beryllium and beryllium compounds on surfaces using the dry wipe sampling method, or both. These samples are collected in a manner that will permit subsequent extraction and determination of beryllium and compounds in the wipes using laboratory analysis techniques such as atomic spectrometry or fluorescence detection.1.2 This practice is limited in its scope to applications where wetted wipe sampling (using Practice D6966) or vacuum sampling (using Practice D7144) is not physically feasible (for example, if the surface to be wiped would be compromised by use of wetted wipes).1.3 This practice does not address the sampling design criteria (that is, sampling plan which includes the number and location of samples) that are used for clearance, hazard evaluation, risk assessment, and other purposes. To provide for valid conclusions, sufficient numbers of samples should be obtained as directed by a sampling plan. Additional guidance is provided in Guide D7659.1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 A properly collected sample that includes the total coal bed interval provides a sample that is a representative cross section of the coal bed at the point of sampling. Core samples are taken for subsequent testing needed for evaluation of coal quality and characterization for commercial evaluations, for planning of mining operations to maintain coal quality, for the determination of coal rank in accordance with Classification D388, and for geologic coal resource studies.NOTE 1: Because of the potential for lateral variability, a sample may not represent the quality of the coal bed at another sample point. The reliability of the data generated from core samples is dependent on the number and spacing of the sample points and the variability of the coal characteristics in a given area.5.2 Moisture determined directly from a core sample shall be considered questionable in any core sample because of possible contamination from drilling fluids and groundwater. If a more representative estimate of the inherent moisture content of the core sample (with the exception of certain low-rank coals) is desired, the sample should be analyzed according to Test Method D1412.1.1 This practice describes procedures for collecting and handling a coal sample from a core recovered from a borehole.1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This guide is written for all persons involved with HHWCs, but especially for those primarily responsible for establishing and providing training to workers at HHWCs. This guide is intended to provide recommended training topics which should be covered during the initial baseline and annual refresher training. The actual topics and depth of training for each worker must be assessed by the HHWC operator on a case-by-case basis with emphasis on the particular job assignment for each worker. The major factors the operator should consider are what are the anticipated hazards to which each worker may be exposed and what are the controls/work practices which the worker must know in order to do his or her job assignments safely.Another factor which the operator must consider is the areas in which each worker is expected to work or the areas to which each worker has access to as part of job assignments. For example, if an administrative assistant only has access to the office area, and never enters the active HHWC area, then training may be limited to required actions as part of the contingency plan. If, however, the administrative assistant is periodically required to enter into the active HHWC area, more detailed training is required based on anticipated hazards which the administrative assistant may be exposed to while in the HHWC area.When deciding on the training topics for the annual refresher training, the HHWC operator must decide on topics in Section 7 which are relevant to the HHWC workers attending the refresher training class. Factors which should be considered are:4.3.1 Hazards to which the workers may be exposed to,4.3.2 Changes in the standard operating procedures, contingency plan since the previous training,4.3.3 Length of time from which a worker has received training in the topics listed in Section 7, and4.3.4 Identification of incidents, hazards, unsafe conditions, or any other situations which indicate a need to retrain workers in a particular topic to ensure a safe and healthful workplace.1.1 This guide covers recommended health and safety training topics for workers at operations for the collection of household hazardous waste or conditionally exempt small quantity generator waste, or both, regardless of the type of collection. Although this guide is intended to protect the worker, public health, and the environment, it is not intended to satisfy all the health and safety training requirements under the Occupational Safety and Health Act of 1970 or the Resource Conservation and Recovery Act of 1976. Additionally, local and state requirements may also vary. Therefore, it is recommended that the operator of a household hazardous waste collection operation also check federal, state, and local regulations for additional requirements.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this guide to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Although this practice is intended for the collection of soil samples from bare areas in and around buildings, this practice may also be used to collect soil samples from other areas and environments.5.2 This practice limits soil collection to approximately the top 1.5 cm (0.6 in.) of soil surface.5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1726 or E1979 and determination of lead using laboratory analysis techniques such as Test Methods E3193 or E3203.1.1 This practice covers the collection of bare soil samples from areas around buildings and related structures using coring and scooping methods.1.2 This practice may not be suitable for collection of soil samples from areas that are paved or otherwise covered with grass, mulch, or the like. See Guide E2115 or Practices E2271/E2271M or E3074/E3074M.1.3 This practice does not address the sampling design criteria (that is, sampling plan that includes the number and location of samples) that are used for risk assessment and other lead hazard activities.1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.1.5 The values stated in SI units are to be regarded as standard.

5.1 This practice is intended for the collection of settled dust samples in and around buildings and related structures for the subsequent determination of lead content in a manner consistent with that described in the HUD Guidelines and 40 CFR 745.63. The practice is meant for use in the collection of settled dust samples that are of interest in clearance, hazard assessment, risk assessment, and other purposes.5.2 Use of different pressures applied to the sampled surface along with the use of different wiping patterns contribute to collection variability. Thus, the sampling result can vary between operators performing collection from identical surfaces as a result of collection variables. Collection for any group of sampling locations at a given sampling site is best when limited to a single operator.5.3 This practice is recommended for the collection of settled dust samples from hard, relatively smooth, nonporous surfaces. This practice is less effective for collecting settled dust samples from surfaces with substantial texture such as rough concrete, brickwork, textured ceilings, and soft fibrous surfaces such as upholstery and carpeting.1.1 This practice covers the collection of settled lead-containing dust on surfaces using the wipe sampling method. These samples are collected in a manner that will permit subsequent extraction (see Practices E1644 and E1979) and determination of lead using laboratory analysis techniques such as atomic spectrometry (see Test Methods E3193/E3193M and E3203) or electroanalysis (see Practice E2051). For collection of settled dust samples for determination of lead and other metals, use Practice D6966.1.2 This practice does not address the sampling design criteria (that is, sampling plan which includes the number and location of samples) that are used for clearance (see Practices E2271/E2271M and E3074/E3074M), lead hazard evaluation, or risk assessment (see Guide E2115), and other purposes. To provide for valid conclusions, sufficient numbers of samples should be obtained as directed by a sampling plan.1.3 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 Although this practice is intended for the collection of dried paint samples in and around buildings for the subsequent determination of lead content, this practice may also be used to collect paint samples from other structures for lead analysis.35.2 The variability associated with the sampling of dried paint is generally considered to be far higher than the variability associated with the analyses of the paint specimens. Therefore, it is essential that sample collection be properly controlled to produce representative and meaningful samples.5.3 These samples are collected in a manner that will permit subsequent digestion using sample preparation techniques such as Practices E1645 or E1979 and determination of lead using laboratory analysis techniques such as inductively coupled plasma atomic emission spectrometry (ICP-AES) (see Test Method E3203) or flame atomic absorption spectrometry (FAAS) (see Test Method E3193).1.1 This practice covers the collection of samples of dried paint and other coatings from buildings.1.2 This practice is used to collect samples for subsequent determination of lead on an area basis (milligrams of lead per area sampled) or concentration basis (milligrams of lead per gram of dried paint collected or mass percent of lead in the paint sample collected).1.3 This practice does not address the sampling design criteria (that is, sampling plan that includes the number and location of samples) that are used for risk assessment and other lead hazard activities. See Guide E2115 or Practices E2271/E2271M or E3074/E3074M.1.4 This practice contains notes that are explanatory and are not part of the mandatory requirements of this practice.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific warning statement is given in 7.4.1.1.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This guide on the proper collection of emission and discharge wastes from glycol dehydrators is applicable to any natural gas industry and supplier that operates glycol dehydration units and that needs to identify which glycol units may have emissions above regulatory levels.The emission and discharge sampling methods discussed in this guide are not regulatory standards. Standard protocols have been developed by the Gas Research Institute (3) and other gas associations (4) and some state regulatory agencies such as the Louisiana Department of Environmental Quality (LDEQ) (5) and the Texas Natural Resource Conservation Commission (TNRCC) (6) are accepting these data. This guide is not intended to instruct the user on how to perform the sampling using these protocols, but to make the user aware of certain practical considerations generally associated with sampling these waste streams.1.1 Purpose This guide covers the proper collection of field emission and discharge data associated with glycol dehydration units used in the natural gas production, processing, transmission, storage, and distribution industries.1.2 Background:1.2.1 Increasing regulatory pressure has made emissions of benzene, toluene, ethylbenzene, and xylene isomers (collectively known as BTEX) and volatile organic compounds (VOCs) from the still vent of glycol dehydration units a major concern of the natural gas industry. The Clean Air Act Amendments (CAAA) of 1990 have been the impetus for air toxics regulations, and several states are regulating or are considering regulating emissions from glycol units (1). Liquid and solid waste discharges are exempt from Subtitle C (hazardous waste) regulation under the Resource Conservation and Recovery Act (RCRA), but may be regulated in the future (2).1.2.2 Measurement of the waste streams from dehydrators is important to determine which units may have emissions above levels of regulatory concern. Measurements of air emissions from glycol dehydration units have been made from a variety of sampling points using different sampling protocols and analytical techniques since no standard methods have been developed by the United States Environmental Protection Agency (USEPA) or state regulatory agencies. Standard sampling methods do not exist for the liquid and solid waste streams since they are exempt from RCRA Subtitle C. The lack of standard protocols has meant that variations of this approach can result in very different emissions measurements (3).1.2.3 Providing guidance on the collection of field emission and discharge data will allow the natural gas industry to quantify emissions and apply appropriate controls to comply with regulations.1.3 Summary--This guide has several parts and an annex. Section 1 is . Section 2 is Terminology that has definitions of terms commonly used with relation to glycol dehydration units in the natural gas industry. Section 3 is of this guide. Section 4 is a process description of glycol dehydration units. Section 5 is a discussion of the waste streams associated with glycol dehydrators. Section 6 presents the Approaches for Collecting Air Emission Data, while Sections 7 and 8 present the approaches for collecting liquid and solid waste discharge data, respectively. The annex includes a standard operating procedure (SOP) for the rich/lean glycol sampling method discussed in this guide.1.4 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This guide is for the use of disposable handheld soil core samplers in collecting and storing approximately 5 or 25 g soil samples for volatile organic analysis in a manner that reduces loss of contaminants due to volatilization or biodegradation. In general, an initial soil core sample is collected (see Guides D6169/D6169M and D6282/D6282M) and the disposable handheld soil core sampler is then used to collect the 5 or 25 g soil sample from the initial soil core sample. The disposable handheld soil core sampler can also serve as a sample storage chamber.5.2 The physical integrity of the soil sample is maintained during sample collection, storage, and transfer in the laboratory for analysis or preservation.5.3 During sample collection, storage, and transfer, there is very limited exposure of the sample to the atmosphere.5.4 Laboratory subsampling is not required for samples collected following this guide. The sample is expelled directly from the coring body/storage chamber into the appropriate container for analysis, or preservation, at the analytical laboratory without disrupting the integrity of the sample. Subsampling from the disposable handheld soil core sampler should not be performed to obtain smaller sample sizes for analysis.5.5 This guide specifies sample storage in the disposable handheld soil core sampler at 4 ± 2°C for up to 48 h.5.6 This guide does not use methanol preservation or other chemical preservatives in the field. As a result, there are no problems associated with flammability hazards, shipping restrictions, or dilution of samples containing low volatile concentrations due to solvents being added to samples in the field.5.7 The disposable handheld soil core samplers are single-use devices. They should not be cleaned or reused.5.8 This disposable handheld soil core samplers cannot be used for collecting cemented material, consolidated material, or material having fragments wider than the mouth of the device or coarse enough to interfere with proper coring techniques.NOTE 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective sampling. Users of this practice are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.Practice D3740 was developed for agencies engaged in the laboratory testing and/or inspection of soil and rock. As such, it is not totally applicable to agencies performing this practice. However, user of this practice should recognize that the framework of practice D3740 is appropriate for evaluating the quality of an agency performing this practice. Currently there is no known qualifying national authority that inspects agencies that perform this practice.1.1 This guide is intended for application to soils that may contain volatile organic compounds.1.2 This guide provides a general procedure and considerations associated with using a disposable handheld soil core sampler to collect and temporarily store a soil sample for volatile organic analysis.1.3 In general, an initial soil sample is collected (see Guides D6169/D6169M and D6282/D6282M) and the disposable handheld soil core sampler is then used to collect the 5 or 25 g soil sample from the initial soil core sample. The disposable handheld soil core sampler can also serve as a sample storage chamber. It is recommended that this standard be used in conjunction with Guides D4547, D4687, D6169/D6169M, D6232, D6282/D6282M, D6418, and D6640, as appropriate, which provide information on the collection of the initial soil core sample.1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.1.5 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action.
