1、Designation: E 2637 08Standard Guide forUtilizing the Environmental Cost Element StructurePresented by Classification E 21501This standard is issued under the fixed designation E 2637; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision

2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 The Environmental Cost Element Structure (ECES)covered by Classification E 2150 (and Adjunct E 2150) pro

3、-vides a consistent and comprehensive structure across allphases of environmental remediation projects and is a tool toimprove the cost management of those projects. This guide isintended to facilitate the application of the ECES to anyenvironmental remediation project, without regard to projectsize

4、.1.2 Classification E 2150 establishes the broad, top-levelframework for environmental remediation projects by provid-ing a hierarchical list of project elements to two levels of detail.Its associated Adjunct E 2150 supports the top-level structureby providing more detailed elements and definitions

5、of theECES to three additional levels of detail. Although it isassumed that the user is familiar with Classification E 2150,much of the content of the classification is repeated in thisguide to relieve the user of the burden of back-and-forthreferencing during use. It is assumed, however, that all u

6、sers ofthis guide will have at hand both Classification E 2150 and theAdjunct E 2150 during project planning.1.3 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety con

7、cerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

RCRA also establishes standardsfor these

Procedure6.1 Overall StructureThe hierarchical nature of the ECEScost structure (Fig. 1) allows detailed cost data at Level 3 to besummarized into higher level cos

15、t elements in a standardizedfashion. It is recommended that the ECES be used as acommon standard through its top three levels. The use of Level4 or lower is optional. Similarly, while Level 5 is generallydeemed to provide a sufficiently low level of detail for mostprojects, the project managers are

16、free to add further lowerlevels for their specific projects or portions of their projects.Care must be taken in developing the associated numericalcodes, however, to assure that each level directly relates to thenext higher level so that the project costs can readily be “rolledup” for reporting purp

17、oses.6.2 Level 1Level 1 of the structure includes seven costcategories. The first six categories represent the six life-cyclephases of an environmental project. The final categoryFIG. 1 Hierarchical Structure of the Environmental Cost Element StructureE2637082Program Management, Support, and Infrast

18、ructureis in-cluded to address costs that are not attributable to a distinctproject or are program management costs. Throughout the restof this guide, the Level 1 cost element for Program Manage-ment, Support, and Infrastructure will be referred-to as Phase8, to simplify references to the Level 1 co

19、st elements. Withminor variations in the definitions, these project life-cyclecategories apply to all environmental projects and programs,including environmental remediation, waste management, de-contamination and decommissioning, ordnance and explosiveretrievals, underground and above-ground storag

22、rameters for all Level 3 ECES elements must beidentified. The purpose of secondary parameters is to identifyand capture those characteristics that impact environmentalmanagement project cost. Cost driving parameters are data thatcharacterize activities or sub-activities and significantly effectcost.

23、 These cost driving parameters are readily available to thework managers who are acquainted with the work and can beincluded while reporting the cost data without requiringadditional resources. As an example, Element 4.18.01 (Phase4) Extraction Wells will commonly have an associated param-eter of ea

24、ch (that is, $X/each well). However, additional costdriving parameters are necessary to define this activity in ameaningful way. The additional cost driving parameters for thisactivity would include depth and diameter of the well, theconstruction material of the well, site conditions or physicalstat

25、e of media, and other parameters. Other typical cost drivingparameters might be given in terms of square feet, pounds,tons, gallons, cubic meters, etc. This information should bereadily available to the project manager, and should be re-corded in a format (for example, tabular) that is conducive tod

26、atabase entry and management. The objective is to be asprecise and descriptive as possible for cost managementpurposes, as well as for cost comparisons among similarprojects. In environmental clean-up projects, the type of wastegenerated becomes a key cost driving parameter because of theregulatory

27、requirements for packaging, handling, transporta-tion, and disposal. Appendix X2 proposes a roster of wastecategories, and Appendix X3 presents numerous other second-ary parameters related to the ECES Level 3 elements.7.

32、structureAPPENDIXES(Nonmandatory Information)X1. EXAMPLE OF USE OF THE ECESX1.1 The following example is provided to show how touse the ECES throughout the life-cycle of a project. Thishypothetical project involves a site that may or may not becontaminated with organic and inorganic hazardous waste.

33、X1.2 Project DescriptionThe site is located in theMid-Atlantic region of the country with very sandy soil andshallow groundwater. The assessment conducted discoveredthat the groundwater is contaminated with benzene, toluene,ethylbenzene, and xylene (BTEX), lead, and high levels ofarsenic. As part of

34、 Phase 2 studies, it was also found that thecontaminants pose an unacceptable risk to a nearby commu-nity. Based on a cleanup technology alternative study, engi-neers will select groundwater pumping followed bycoagulation/flocculation/precipitation and ion exchange as afinal step. The treatment unit

35、s need to treat approximately onemillion gallons of groundwater per day. To remove the BTEX,Ultraviolet Photolysis will be used. A treatment train will bedesigned and constructed to clean up the site. The technologies(treatment train) will be housed in a treatment train facility. TheO additional cos

36、t driving parameters forall Level 3 ECES elements must be identified. The purpose ofsecondary parameters is to identify and capture those charac-teristics that impact environmental management project cost.X3.2 Cost driving parameters are data that characterizeactivities or sub-activities and signifi

37、cantly effect cost. Thesecost driving parameters are readily available to the workmanagers who are acquainted with the work and can beincluded while reporting the cost data without requiringadditional resources. As an example, Element 4.18.01 (Phase4) Extraction Wells will commonly have an associate

38、d param-eter of each (that is, $X/each well). However, additional costdriving parameters are necessary to define this activity in ameaningful way. The additional cost driving parameters for thisactivity would include depth and diameter of the well, theconstruction material of the well, site conditio

39、ns, or physicalstate of media and other parameters. This information shouldbe readily available to the work manager.X3.3 The cost driving parameters associated with Level 3elements of ECES are presented in a matrix format. The firstrow of the matrix identifies the secondary parameters ormeasures whi

40、le the first four columns represents the ECESnumbers and titles. The numbers marked within the matrixrepresents those ECES phases where these parameters are mostapplicable and the bolded numbers represent primary unit ofmeasure. The numbers are used as a guideline, and users arefree to use any param

41、eters as appropriate. For example, theWBS Element X.22.09, Trickling Filter, is marked with thenumbers “4,5” in Materials Used column. This indicates thatduring both Phases 4 and 5, the materials used are one of thecosts driving parameters.X3.4 Among the key cost driving parameters in environ-mental

42、 clean-up projects is the type of waste generated,because of the regulatory requirements governing their pack-aging, handling, transportation, and disposal. The more diffi-cult and dangerous the waste, the more stringent are thoserequirements. Accordingly, the following matrix provides forTABLE X2.1
