0 VI. SUMMARY AND CONCLUSIONS <br />n <br />General siting criteria for Class III nonhazardous solid waste dis- <br />posal facilities is contained in Section 2533, Article 3 of Subchap- <br />ter 15. Key elements of the criteria are: <br />• Class III landfills will be located where site charac- <br />teristics provide adequate separation between nonhazard- <br />ous solid waste and waters of the State. <br />• New Class III landfills will be sited where soil charac- <br />teristics, distance from waste to ground water, and other <br />factors will ensure no impairment of beneficial uses of <br />surface water or ground water beneath or adjacent to the <br />landfill. <br />• Where site location factors indicate that site character- <br />istics alone do not ensure protection of the quality of <br />ground water or surface water, Class III landfills will <br />be require to have a single clay liner with permeability <br />of 1 x 10 cm/sec or less. <br />• New Class III landfills will not be located on a known <br />Holocene fault. <br />Evaluation of data presented in the report indicates that the Landfill <br />Development Site is suitable with proper engineering as a Class III <br />disposal facility. This conclusion is based on the following: <br />• Depth to ground water; currently greater than 125 feet, <br />historically greater than 40 to 50 feet <br />• Presence of low -permeability clay/silt deposits composing <br />the unsaturated zone underlying the site (1 x 10-6 to <br />1 x 10-8 cm/sec) <br />• Lack of nearby, permanent surface -water bodies <br />• Availability of on-site low -permeability soils for use in <br />construction of liners and other hydraulic barriers as <br />required <br />• No Holocene faults crossing the site <br />o # i <br />
