Standard Guide for Sampling Oil/Water Mixtures for Oil Spill Recovery Equipment

Standard Guide for Sampling Oil/Water Mixtures for Oil Spill Recovery Equipment

SIGNIFICANCE AND USE
3.1 This guide provides techniques for obtaining representative samples of oil and water mixtures. This information is necessary in the calculation of oil recovery efficiency and oil recovery rates for oil collection devices.  
3.2 Sampling Stationary Mixtures—When recovered oil/water mixtures are contained within a holding tank and the relative oil content of the recovered fluid is needed, the sampling technique is somewhat dependent on the container. Two techniques are outlined in this guide. If the container has a flat bottom with straight sides perpendicular to the base (or nearly so), either stationary technique can be implemented, with the stratified sampling method preferred. If the container is irregular in either the horizontal or vertical cross section, the mixing method is preferred.  
3.3 Sampling Flowing Mixtures—To sample flowing mixtures containing both oil and water, turbulence is induced, to create a homogenous mixture while sampling. The oil content in the sample taken from the flowing stream can then be used to quantify the performance-rating criterion (see Procedure Section of Test Method D1796).
SCOPE
1.1 This guide is intended for sampling flowing or stationary oil/water mixtures. It is intended for use with oil spill recovery devices either in testing or in documentation of field performance.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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 and health practices and determine the applicability of regulatory limitations prior to use.

8.2 Sampling from a Container—This procedure is intended
for taking a representative sample of collected fluids held in a
container. When sampling containers, it is advisable to remove
as much of the aqueous phase as possible prior to sampling. If
this is possible, measure and record the volume of water
removed, which will contain dissolved hydrocarbons, for later
calculation of the relative oil/water composition. The precision
of the measurement will improve with removal of the aqueous
phase.
8.2.1 Mixing Method:
8.2.1.1 Mix the container of stratified oil and water using
any method which will achieve homogeneity during sampling
(high-speed propeller, liquid jet, or homogenizing pump).
Operate the mixer for a minimum of 5 min. Longer mixing
times are preferable to ensure homogeneity.
NOTE 1—Although this mixing method has been geared toward electric
mixers, alternate mixing methods could be used (air or liquid mixing jets,
homogenizing pumps), so long as a homogeneous mixture of the entire
volume is created. Immediately after mixing, obtain a representative
sample of the homogeneous mixture by lowering a 250 to 500-mL

slow rate from the surface of the mixture to the bottom of the tank.
Immediately remove the bottle by slowly raising it through the mixture. If
necessary, repeat the process to ensure that at least 50 mL of sample will
be available for laboratory analysis. Do not fill the bottle to the top.

Standard Test Method for Determination of Deposition of Aerially Applied Oil Spill Dispersants

SIGNIFICANCE AND USE
3.1 The deposition of an aerially applied dispersant is defined as the amount of an aerially applied dispersant that contacts the surface; whereas, application dosage (frequently referred to as application rate) is the amount of material that is released per unit area by the delivery system. The units of deposition are litres per hectare or U.S. gallons per acre. The deposition may differ from the application dosage (volume of material per unit area) for many reasons, such as, the effects of wind on the spray and the evaporation of the dispersant after it has been released from the aircraft.  
3.2 This test method describes the measurement of the ability of a spray system to deposit a dispersant on oil. It is not intended that this test method be used at the time of a spill. These techniques are intended to determine the equipment performance during the development of new systems and after the repair or significant modification of a system.  
3.3 The data obtained from the use of this test method can be directly related to the deposition of dispersant on an oil slick, and thus can serve to determine both the dispersant deposition and the drop size.  
3.4 Surrogate deposition and drop size data can be used as a technical basis for the optimization of dispersant application equipment and its use.  
3.5 The choice of a dispersant surrogate may vary, typically water is chosen along with a marker dye.
SCOPE
1.1 This test method covers the measurement of the deposition of an aerially applied dispersant surrogate, typically dyed water, on the surface of the ground or water. The test method of obtaining these measurements is described, and the analysis of the results, in terms of dispersant use, is considered. There are a number of techniques that have been developed, and this test method outlines their application. These measurements can be used to confirm or verify the specifications of a given equipment set, its proper functioning, and use.  
1.2 This test method is applicable to systems used with helicopters or airplanes.  
1.3 This test method is one of four related to dispersant application systems. Guide F1413/F1413M covers design, Practice F1460/F1460M covers calibration, Test Method F1738 covers deposition, and Guide F1737/F1737M covers the use of the systems. Familiarity with all four standards is recommended.  
1.4 There are some exposure and occupational health concerns regarding the methods described. These are not discussed in this test method since they are a function of dispersant formulation. Anyone undertaking such experiments should consult the occupational health experts of the dispersant manufacturer regarding the precautions to be used.  
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.  
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.

Standard Practice for Classifying Water Bodies for Spill Control Systems

SIGNIFICANCE AND USE
4.1 This practice is to be used as a guide to classify water bodies for spill control systems. These classifications may be used in formulating standards for design, performance, evaluation, contingency and response planning, contingency and response plan evaluation, and standard practice for spill control systems.  
4.2 Relatively few parameters of broad range have been used in Table 1 in order to enable the user to readily identify general conditions under which spill control systems can be used.  
4.3 Satisfactory operation of any specific spill control systems may not extend over the full range of conditions identified by Table 1. Detailed discussion with systems suppliers is recommended.  
4.4 Effective operation of oil spill control equipment depends on many factors, of which the prevailing environmental conditions are just a few. Factors such as, but not limited to, deployment techniques, level of training, personnel performance, and mechanical reliability can also affect equipment performance.
SCOPE
1.1 This practice creates a system of categories that classify water bodies relating to the control of spills of oil and other substances that float on or into a body of water.  
1.2 This practice does not address the compatibility of spill control equipment with spill products. It is the user's responsibility to ensure that any equipment selected is compatible with anticipated products.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 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.  
1.5 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.

Standard Guide for In-Situ Burning of Oil Spills on Water: Environmental and Operational Considerations

SIGNIFICANCE AND USE
4.1 This guide is primarily intended to aid decision-makers and spill-responders in contingency planning, spill response, and training.  
4.2 This guide is not specific to either site or type of oil.
SCOPE
1.1 This guide covers the use of in-situ burning to assist in the control of oil spills on water. This guide is not applicable to in-situ burning of oil on land or the disposal of oil or oiled debris in incinerators.  
1.2 The purpose of this guide is to provide information that will enable spill responders to decide if burning will be used as part of the oil spill cleanup response. Other standards address the use of ignition devices (Guide F1990), the use of fire-resistant boom (Guide F2152), the use of burning in ice conditions (Guide F2230), the application of in-situ burning in ships (Guide F2533), and the use of in-situ burning in marshes (Guide F2823).  
1.3 This is a general guide only. It is assumed that conditions at the spill site have been assessed and that these conditions are suitable for the burning of oil. It is also assumed that permission to burn the oil has been obtained from appropriate regulatory authorities. Variations in the behavior of different oil types are not dealt with and may change some of the parameters noted in this guide.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4.1 Exception—Alternate units are included in 7.5, 7.7, and 7.8.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Guide for Maintenance and Rehabilitation of Groundwater Monitoring Wells

SIGNIFICANCE AND USE
4.1 The process of operating any engineered system, such as monitoring wells, includes active maintenance to prevent, mitigate, or reverse deterioration. Lack of or improper maintenance can lead to well performance deficiencies (physical problems) or sample quality degradation (chemical problems). These problems are intrinsic to monitoring wells, which are often left idle for long periods of time (as long as a year), installed in non-aquifer materials, and installed to evaluate contamination that can cause locally anomalous hydrogeochemical conditions. The typical solutions for these physical and chemical problems that would be applied by owners and operators of water supply, dewatering, recharge, and other wells may not be appropriate for monitoring wells because of the need to minimize their impact on the conditions that monitoring wells were installed to evaluate.  
4.2 This guide covers actions and procedures, but is not an encyclopedic guide to well maintenance. Well maintenance planning and execution is highly site and well specific.  
4.3 The design of maintenance and rehabilitation programs and the identification of the need for rehabilitation should be based on objective observation and testing, and by individuals knowledgeable and experienced in well maintenance and rehabilitation. Users of this guide are encouraged to consult the references provided.  
4.4 For additional information see Test Methods D4412, D5472/D5472M, D7726 and Guides D4448, D5254/D5254M, D5521/D5521M, D5409/D5409M, D5410 and D5474.
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 testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results...
SCOPE
1.1 This guide covers an approach to selecting and implementing a well maintenance and rehabilitation program for groundwater monitoring wells. It provides information on symptoms of problems or deficiencies that indicate the need for maintenance and rehabilitation. It is limited to monitoring wells, that are designed and operated to provide access to, representative water samples from, and information about the hydraulic properties of the saturated subsurface while minimizing impact on the monitored zone. Some methods described herein may apply to other types of wells although the range of maintenance and rehabilitation treatment methods suitable for monitoring wells is more restricted than for other types of wells. Monitoring wells include their associated pumps and surface equipment.  
1.2 This guide is affected by governmental regulations and by site specific geological, hydrogeological, geochemical, climatological, and biological conditions.  
1.3 Units—The values stated in either inch-pound units or SI units presented in brackets are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
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 ...

Standard Practice for Laboratory Performance Verification of Hydrodynamic Separators for the Treatment of Stormwater Runoff

SIGNIFICANCE AND USE
4.1 This practice provides criteria for the verification of the silica sediment removal efficiency of hydrodynamic separators.  
4.2 Verification can be used to support certification of the technology within different AHJs provided that:  
4.2.1 HDS units are sized using the resulting performance data to treat the prescribed water quality flow rate or annual mass load requirement at the level of performance desired by the certifying entity.  
4.2.2 Scaling of results to different MTD model sizes is in accordance with this standard.  
4.2.3 The technology is designed consistently with the tested unit such that it operates within the specified limits determined by the verification as well as other restrictions placed by the certification entity.
SCOPE
1.1 This practice covers the criteria for the laboratory verification of Hydrodynamic Separators (HDS) as it relates to the removal of suspended solids in stormwater runoff.  
1.2 HDS manufactured treatment devices are placed as offline or online treatment devices along storm drain pipe lines to remove suspended solids and associated pollutants from stormwater runoff. These devices may be used to target removal of other pollutants which are not covered in this standard. The criteria in this standard specifically relate to the removal of silica particles in controlled laboratory conditions, which is considered an appropriate surrogate for predicting the removal of stormwater solids from actual stormwater runoff.  
1.3 This practice provides guidelines for independent regulatory entities, collectively referred to as Authority Having Jurisdictions (AHJs), to streamline data requirements for the certification of HDS devices within their jurisdiction. For any given AHJ, additional criteria may also apply.  
1.4 Units—The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall not be regarded as non-conformance with this test method.  
1.5 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan (QAPP), a specific verification protocol, or AHJ. It is advised to review one or all of the above to ensure compliance.  
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.
Note 1: This practice is also intended to ensure that the data resulting from completion of testing in accordance with the ASTM test methods referenced herein can be utilized to satisfy the requirements of the New Jersey Department of Environmental Protection’s manufactured treatment device (MTD) certification process.  
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.
