6、 of Engineers, July 1997; and4.2 Quality Assurance and Quality Control for Waste Containment Facilities, TechnicalGuidance, EPA/6001R-93/182, Environmental Protection Agency, September 1993.5. Discussion.The federally mandated requirements for the components of a hazardous waste landfill aredescribe

7、d in the Code of Federal Regulations (CFR) 40 CFR 264. State and local governmentagencies also have criteria for landfill systems and, in some instances, these criteria may be morestringent than federal guidelines. In general, the components of landfill covers and liners consistof protective cover s

8、oil layers, drainage layers, and low permeability layers. Many landfill coversalso contain some type of gas control system. Drainage layers and low permeability layers arefrequently constructed of geosynthetics. The term geosynthetic refers to plastic manufacturedmaterials such as geotextiles, geome

9、mbranes, geonets, geogrids, and geocomposites.The responsibilities of the CQA inspector are similar regardless of the regulatory criteria underwhich a landfill is being designed and constructed. The CQA inspector must verify that all soillayers, geosynthetic layers, and appurtenances are constructed

10、 in accordance with the plans andspecifications. USACE personnel have traditionally performed CQA inspection duties on USACEProvided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-EM-1110-1-40111 Oct 99construction projects. However, at some landfill sites,

11、a third party CQA inspector has been hiredto observe the construction of some or all of the landfill. This has been done because of theamount of documentation required and the unique CQA inspection requirements involved with theconstruction of geosynthetic layers in landfills.The attached standard C

12、QA plan can be used as a tool in defining the responsibilities of a thirdparty CQA inspector. It can also be used if USACE inspectors will be responsible for all CQAactivities. However, manpower limitations may prevent USACE inspectors from performing all ofthe CQA duties outlined in this standard p

13、lan. The amount of documentation required by this planis extensive and may be reduced on a site specific basis, depending on regulatory requirements.The designer should contact the regulatory authorities to determine what CQA documentationthey require.The strict CQA requirements for landfills requir

14、es coordination between the designer and fieldoffices to determine manpower needs and to determine how much work can be performed byUSACE inspectors. Work that cannot be performed by USACE inspectors will have to beperformed by a third party inspector. Funds needed to perform CQA on landfills will a

15、lso begreater than for most other types of construction projects. Because of this, tinding needs forCQA should be addressed during design and coordinated with the field office.6. Actions Required. The topics listed in this document should be considered in thepreparation of a CQA plan for any landfil

16、l constructed by the USACE. It is stronglyrecommended that input be sought from the appropriate regulatory and in-house technical staff inthe preparation of any CQA plan for a landfill. The involvement of in-house technical expertise isessential to providing a cost-effective, high quality service to

17、 the customer.7. Format. This manual provides a template for a standard CQA plan for hazardous wastelandfills. The standard CQA plan is presented in Appendix A and is divided into sections witheach section covering a unique aspect of CQA for landfill construction. The standard CQA planmust be modifi

18、ed on a site specific basis. Sections which are not applicable should be deleted.Applicable sections should be edited to meet the site specific needs of a project. Notes to thedesigner are also provided within the text of the standard CQA plan to provide guidance on howto edit the document.2Provided
