It does not apply to geosynthetics used as an ADC.1.2 This standard addresses the evaluation of an ADC andits ability to control fires and odors and whether or not thecover contains materials that present a threat to human healthand the

5、environment. The control of disease vectors andblowing litter can be evaluated by observation, and scavengingis controlled by security procedures and other operatingpractices.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

16、3).4. Significance and Use4.1 The U.S. Environmental Protection Agency promul-gated regulations under the Resource Conservation and Recov-ery Act, Subtitle D, which establish criteria for municipal solidwaste landfills (MSWLF). These regulations became effectiveOctober 9, 1991. The cover material re

17、quirements of theseregulations are set forth in 40 Code of Federal Regulations,Section 258.21 as follows:(a) “Except as provided in paragraph (b) of this section, theowners or operators of all MSWLF units must cover disposedsolid waste with six inches of earthen material at the end ofeach operating

18、day, or at more frequent intervals if necessary,to control disease vectors, fires, odors, blowing litter, andscavenging.”(b) “Alternative materials of an alternative thickness (otherthan at least six inches of earthen material) may be approved bythe Director of the Solid Waste Regulatory Agency of a

19、napproved State if the owner or operator demonstrates that thealternative material and thickness control disease vectors, fires,odors, blowing litter, and scavenging without presenting athreat to human health and the environment.”These federal regulations have the force of the law, and it isthe purp

20、ose of this specification to define the test proceduresnecessary to comply with these regulations.4.2 In order for a MSWLF landfill operator to obtainapproval for use of an ADC, the operator must supplyperformance data to the state Solid Waste Regulatory Agency.In general, the technique used to obta

21、in this permissioninvolves applying to the state Solid Waste Regulatory agencyfor a sanitary MSWLF operating permit modification.NOTE 1Manufacturers will provide performance data for their prod-uct.4.3 Parties interested in the evaluation technology describedin the Standard Practice should include M

22、SWLF operators,engineering firms, local, state, and federal Solid Waste Regu-latory Agencies, and manufacturers and vendors of ADCmaterials.5. Classification of ADCs (Other than GeosyntheticADCs)5.1 FoamsFoam ADCs are applied to the working face ofMSWLF units using foam generation and application eq

23、uip-ment specifically designed for that particular foam. Bothhardening and non-hardening foams are currently available.5.2 Spray-On SlurriesMostADC slurries are paper-based.The paper-based slurry ADCs are applied to the working faceof MSWLF units using standard hydro seeding equipment.Certain types

24、of slurries may require some modification of thehydro seeding equipment. The slurries are allowed to harden toform a crust or shell over the working face.5.3 Indigenous MaterialsIndigenous ADCs consist ofvarious types of locally available waste products (for example,sludges, ash, contaminated soils,

25、 shredded tires, shreddedgreen waste, pulverized construction and demolition debris,automobile recycling fluff, foundry sand, etc.). These indig-enousADCs are placed onto the working face of MSWLF unitsin a manner similar to soil cover. They often require physicalor chemical modification for consist

26、ency and workability andare usually evaluated for the presence of potentially hazardousconstituents. Unlike commercially available ADCs, each ofthese materials can vary significantly in respect of physical andchemical characteristics and composition, depending upon thesource of the indigenous materi

27、al. In addition, suitability andacceptability are dependent on site-specific climatic and opera-tional conditions and regulatory requirements.6. Physical Properties6.1 GeneralThe experimental procedures and results areselected to ensure that the ADC material controls diseasevectors, fires, odors, bl

28、owing litter, and scavenging, and thatthe ADC itself does not present a threat to human health andthe environment.6.2 Control of Fires:6.2.1 Test Method A of Test Methods D 4982, shall be usedto indicate the fire-producing potential of those ADCs coveredby this standard that are sprayed as a slurry,

29、 applied as a foamor indigenous materials that are placed on disposed solid wastein a landfill. Prepare the specimens according to the manufac-turers instructions and condition at 120 F (48.9 C) to constantmass before tests. Constant mass is determined by successiveweighing at two-hour intervals tha

30、t do not change more than1%. Test within 15 min or place the conditioned specimen in adessicator until test is performed.The test result shall be pass orfail.6.3 Control of Odors:6.3.1 The Water Method of Test Methods E96, can be usedto determine the water vapor permeance of a representativesample o

31、f the ADC to be tested. The standard test conditionshall be that set forth in Appendix X1.1.2 Procedure B, WaterMethod at 73.4F (23C).NOTE 2One sprayed-slurry ADC has a measured permeance of 1.813 10-4g/h-cm2-mmHg (Water Method of Test Methods E96) Thepermeance of Ottawa Sand is 2.87 3 10-4g/h-cm2-m

32、mHg when measuredin the same manner.h The lower the water vapor transmission rate, thegreater potential odor control a particularADC may provide. Test MethodsE96test results may be used to compare one ADC to another.6.3.2 The Water Method of Test Methods E96may not beappropriate for some materials.

33、Odor control can be deter-mined by visual observation of the reduction of fly and birdpopulation and by the reduction in scavenging in areas whereADC has been applied.6.4 Analysis of Daily Cover Materials to Ensure They DoNot Present a Threat to Human Health and the Environment:6.4.1 A representativ

34、e sample (samples) of the ADC, as it isexpected to be used at a landfill, shall be collected andanalyzed as follows:6.4.1.1 The sample shall be prepared using the ToxicityCharacteristic Leaching Procedure (TCLP), EPAMethod 1311.The resulting extract must be analyzed for the parameterscontained in 40

35、 CFR 261.24 and with the resulting concentra-tions compared to their corresponding EPA regulatory levels.D6826052Should any of the parameter concentrations in the TCLP testexceed EPAs regulatory levels, then The ADC shall not beallowed for use in landfills.6.4.1.2 The sample must be subjected to tot

36、al analysis for:(a) the eight RCRA metals, and aluminum, antimony, beryl-lium, nickel, sodium, and thallium using the appropriate testmethods for these metals contained in EPA Publication SW-846, latest edition; (b) volatile organic compounds using EPAMethod 8260; and (c) semi-volatile organic compo

37、unds usingEPA Method 8270.6.4.2 Leaching PotentialA representative sample(samples) of the ADC, as it is expected to be used at a landfill,shall be collected and analyzed as follows:6.4.2.1 To evaluate the leaching potential of the ADC, thesample shall be prepared using the Synthetic PrecipitationLea

38、ching Procedure (SPLP), EPA Method 1312. The extractprepared with this procedure shall then be analyzed for: (a) theeight RCRA metals, and aluminum, antimony, beryllium,nickel, sodium, and thallium using the appropriate test methodsfor these metals contained in EPA Publication SW-846, latestedition;

39、 (b) volatile organic compounds using EPA Method8260; and (c) semi-volatile organic compounds using EPAMethod 8270.6.5 Control of Disease Vectors, Blowing Litter, and Scav-enging:6.5.1 The control of disease vectors and blowing litter canbe evaluated by observation.6.5.2 Scavenging is controlled by

40、security procedures andother operating practices.7. Qualified Laboratories7.1 All tests required by this standard shall be conducted ataccredited laboratories.8.
