Sanitary landfills permitted under this chapter shall comply with the following requirements:
(A) Drainage. Sanitary landfills shall be designed and operated to insure proper drainage, to minimize flooding or standing water and to prevent runoff onto adjacent property and run-on onto the facility.
(B) Fill. All solid or liquid waste which is disposed of in a sanitary landfill shall be compacted in layers. The layers of compacted material shall not exceed eight feet in height for each lift. Where the trench system of sanitary landfill is used, successive parallel trenches shall be at least 20 feet apart.
(C) Cover. All solid or liquid waste disposed of in a sanitary landfill shall be covered by at least six inches of cover daily or more frequently as specified in the permit. Landfilled materials shall be leveled and spread at sufficient intervals to prevent unsightly appearance or rodent harborage and shall have a final cover compacted to a depth of not less than 24 inches upon closure.
(D) Grade. The final grade of each sanitary landfill shall be determined by the commissioner, and each permit for a sanitary landfill issued under this chapter shall specify the grade to which the disposal of waste is authorized.
(E) Erosion Control. Erosion control measures shall be implemented once the height of a sanitary landfill reaches ten feet above Chicago City Datum.
(F) Monitoring. Groundwater monitoring wells, at least two of which shall be located upgrade from the facility and four of which shall be located downgrade from the facility, shall be sampled quarterly. All samples shall be analyzed and shall be consistent with regulations issued under the Illinois Environmental Protection Act, P. A. 76-2429. The results of such sampling and analyses shall be sent to the commissioner no later than 45 days after sampling.
(G) Liners. Each trench or the entire landfill, if the trench system is not used, shall have a liner installed prior to commencement of operation in order to minimize the potential for migration of leachate from the site.
(H) Leachate Collection. A leachate collection system shall also be installed prior to commencement of operation. The leachate shall be analyzed by the owner or operator two times per year, and the analyses submitted to the commissioner. Such analyses shall test for all conventional and toxic pollutants designated by the United States Environmental Protection Agency under the Federal Clear Water Act.
