33、3.2.5.1 DiscussionThis professional may include, but maynot be limited to, a Professional Engineer (PE) or ProfessionalGeologist (PG).4. Significance and Use4.1 General:4.1.1 Many CCPs are suitable materials for the constructionof engineered structural fills. CCPs may be used as: structuralfill for

34、building sites and foundations; embankments forhighways and railroads, road bases, dikes, and levees; and inany other application requiring a compacted fill material. Theirlow unit weight, relatively high shear strength, ease ofhandling, and compaction make CCPs useful as fill material.However, the

35、specific engineering and environmental proper-ties of these materials can vary from source to source and mustbe evaluated for each material, or combination of materials, tobe used for an engineered structural fill. Information containedin Guide D5759 may be applicable to some CCPs to be used inengin

36、eered structural fills. AASHTO Standard Practice PP059-09-UL also addresses the use of coal combustion fly ash inembankments. The requirements for the type of CCPs that canbe used for specific engineered structural fills may also varybecause of local site conditions or the intended use of the fill,o

37、r both. Environmental considerations are addressed in Section5.4.1.2 CCPs can be a cost-effective fill material. In manyareas, they are available in bulk quantities at a reasonable cost.The use of CCPs conserves other resources and reduces theexpenditures required for the purchase, permitting, and o

38、pera-tion of a soil borrow pit. CCPs often can be delivered to a jobsite at near optimum moisture content and generally do notrequire additional crushing, screening, or processing as com-pared to comparable native materials.4.1.3 Use of CCPs conserves natural resources by avoidingextraction or minin

39、g of soils, aggregates, or similar fill materialthat also conserves energy and reduces greenhouse gas emis-sions.4.1.4 The volume of beneficially used CCPs preservesvaluable landfill space.4.2 Regulatory Framework:4.2.1 FederalCurrently, there are no federal regulationsaddressing the beneficial use

40、of CCPs. States and local juris-dictions have oversight of CCP management and beneficial useactivities within their states4.2.2 State and Local JurisdictionsLaws and regulationsregarding the use of CCPs vary by state and local jurisdictions.It is incumbent upon the project owner and designer todeter

41、mine any local or state guidance, policies, or regulationspertaining to the use of CCPs.5. Environmental Aspects and Considerations5.1 GeneralAs part of the design phase, it is incumbentupon the designer or registered professional to evaluate theCCPs and to assess the site specific characteristics o

42、f a projectto include appropriate measures to address potential environ-mental impacts. In addition to state or local guidance, screen-ing procedures or analysis techniques should be employed asappropriate to determine, what, if any potential environmentalrisks need to be considered when using CCPs

43、for engineeredstructural fills. Evaluation should include consideration ofmaterials, geography, topography, hydrology, climatology,habitat, existing site conditions, and end use of the land. Fig. 1and Table 1, depict a decision flow diagram that illustrates thepotential steps for the project geotech

44、nical and environmentalevaluation.5.2 Materials CharacterizationMany CCP materials havebeen effectively used for beneficial reuse in engineered struc-tural fills and have been shown to have little or no potential forreleasing constituents to the environment when placed andcompacted at the proper moi

45、sture content and with suitableengineering controls. CCPs contain constituents that may havethe potential to leach into the environment if not properlymanaged. Factors that affect the potential of CCPs to impactthe environment are the presence of constituents of concern,potential for these constitue

46、nts to become available in theenvironment and the presence of complete exposure pathwaysfor human or ecological receptors, or both.5.2.1 Safety ClassificationIn consideration of the differenttypes of CCPs that may be used in the construction ofengineered structural fills the project owner and design

47、ershould prepare or obtain Safety Data Sheets (SDSs) based onthe Occupational Safety and Health Administration (OSHAs)Hazard Communication Standard, 29 CFR Part 1910.1200 andconsider the latest OSHA guidance. If the SDS identifies raisesareas of human health or environmental concern, then theproject

48、 owner or designer may need to consider additionalworker safety precautions, conduct additional site specificenvironmental and human health investigation, or additionaltesting, or a combination thereof, to determine the constituentsin the fill to migrate to an environmental receptor through acomplet

49、e migration pathway. An SDS alone will not identifyall human health and environmental concerns but may serve asa screening tool.5.3 Beneficial Use Site EvaluationThe registered profes-sional shall evaluate if the use of CCPs at a specific engineeredstructural fill project can be implemented in manner that isprotective of human health and the environment. The geotech-nical and environmental evaluation of the proposed site for anengineered structural fill shall include consideration of the stateor local requirements for CCP use, screening procedures todetermine site
