Standard Guide for Harvesting Coal Combustion Products Stored in Active and Inactive Storage Areas for Beneficial Use

SIGNIFICANCE AND USE
4.1 Purpose—This guide provides a process for reclamation of existing CCPs placed in active and inactive storage areas. The guide includes information on the following activities required for the safe and effective reclamation of CCPs from storage areas: (1) Background Review of CCP Storage Areas; (2) Detailed Characterization of CCP Storage Areas; (3) Harvesting Planning and Scoping of CCP Storage Areas; (4) Harvesting Detailed Design and Approval of CCP Storage Areas; and (5) Harvesting Implementation of CCP Storage Areas. More detailed descriptions of these activities are in Sections 6 through 10.  
4.2 Potential Beneficial Uses of CCPs—There are many CCP storage areas that are potentially harvestable and can provide a functional benefit in a wide variety of beneficial uses. The beneficial use of CCPs contained in these storage areas can have significant environmental and economic benefits for the facility, the facility owner and the local economy, and can significantly reduce disposal operations (1-4).4 Beneficial use of CCPs can provide industry with a safe and responsible way to economically manage the CCPs, while promoting conservation and recycling/reuse, meeting sustainability goals, and addressing the shortage of CCPs in some building product market areas (1, 2, 5). CCPs consist of fly ash, bottom ash, boiler slag, fluidized-bed combustion (FBC) ash, economizer ash, and flue gas desulfurization (FGD) material (see Terminology E2201 for definitions of CCPs) (6, 7).  
4.2.1 Fly ash is the most abundant CCP in existing storage areas. Its beneficial uses include, but are not limited to: partial replacement for cement in concrete and concrete products – once in concrete, fly ash reacts with Portland cement to create additional reaction products that improve the strength and durability of concrete; raw feed for the production clinker – fly ash can be calcined along with other minerals to produce clinker; blended cements – fly ash can be an important component ...
SCOPE
1.1 This guide covers a framework to address critical aspects related to the harvesting of CCPs placed in active (operational) and inactive (closed or no longer receiving CCPs) storage areas. These storage areas may be used for wet or dry material, and may be located at active or inactive facilities (that is, coal-fired electric utilities or independent power producers that are currently generating electricity or have ceased to do so, respectively). Also, CCPs may be harvested from active or inactive storage areas located on-site or off-site of the facility.  
1.2 This guide does not include information on how to determine what storage areas or facilities, or both, should be selected for potential harvesting of CCPs, as each entity may approach a harvesting program in accordance with their own harvesting pursuits and regulatory requirements. In addition, it does not include information on how an energy company or other interested parties should evaluate inventories to determine the order of their storage areas for potential harvesting, including consideration of risk, performance, and cost. This guide is intended to be used to evaluate the potential harvesting of the storage areas once the storage areas are selected for evaluation.  
1.3 This guide is comprised of the following sections: Scope, Section 1; Referenced Documents, Section 2; Terminology, Section 3; Significance and Use, Section 4; Project Planning and Scoping, Section 5: Background Review of CCP Storage Areas, Section 6; Detailed Characterization of CCP Storage Areas, Section 7; Harvesting Planning and Scoping of CCP Storage Areas, Section 8; Harvesting Detailed Design and Approval (as applicable) of CCP Storage Areas, Section 9; and Harvesting Implementation of CCP Storage Areas, Section 10. Not all information within this guide will be necessary for each harvesting project, and the user should determine the applicability of each section.

Standard Practice for Calculating Coal and Coke Analyses from As-Determined to Different Bases

SIGNIFICANCE AND USE
4.1 The calculations of analytical data for the coal and coke test parameters listed in Section 6, assume the analysis sample has been prepared according to Practice D2013 and Test Method D3302.  
4.2 This practice provides formulas, to enable calculations of data from the as-determined analysis sample to various moisture bases, in common use by the coal and coke industry.  
4.3 This practice provides guidance to enable calculations of weight-average data from various lots or sublots, which, initially, are provided at different moisture bases.  
4.4 The principles given in this practice are applicable to the calculation of cumulative data (e.g., for trade purposes or for sieve analyses or washability analyses).
SCOPE
1.1 This practice lists formulas that allow analytical data to be expressed in various bases in common use. Such bases are: as received, dry, equilibrium moisture, dry ash free, and others.  
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 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.

ASTM D3466-06(2023)(Test Method)
Standard Test Method for Ignition Temperature of Granular Activated Carbon

SIGNIFICANCE AND USE
5.1 Activated carbons used in gas-phase adsorption may be subjected to heating, either from heat applied externally to the carbon bed, or heat generated by radioactive4 contaminants, or by the adsorption process itself. If the application of heat is sudden, or if no ample means to conduct the heat from the carbon bed exists, the carbon bed may ignite. This test method provides a controlled laboratory test to determine the temperatures at which such ignition occurs. As stated in 1.2, this does not necessarily give the temperature at which ignition will occur under a specific bed operating condition. This test method does, however, allow some ranking of carbons with regard to ignition temperature, and is a useful quality control method for unused carbons.
SCOPE
1.1 This test method covers the determination of reference ignition temperature of granular activated carbon in flowing air. This test method provides a basis for comparing the ignition characteristics of different carbons, or the change in ignition characteristics of the same carbon after a period of service.  
1.2 The ignition temperature, as determined by this test method, cannot be interpreted as the probable ignition temperature of the same carbon under the operating conditions of a specific application unless those conditions are essentially the same as those in this test method.2 If it is desired to determine the ignition temperature of the carbon under a specific set of operating conditions, the test may be modified to simulate such conditions, taking into consideration the following variables: (1) air flow rate; (2) moisture content of the carbon; (3) bed depth; (4) relative humidity of the air stream; (5) heating rate; (6) contaminants (for example, hydrocarbons, etc.) in the air stream; and (7) contaminants that may have been adsorbed by the carbon under prior service conditions.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. Specific precautionary statements are given in Section 7.  
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.
