§ 288.124. Soil description.
(a) An application for a Class I or Class II landfill shall contain:
(1) The depth to the seasonal high water table within the proposed permit area and adjacent area to demonstrate that the seasonal high water table will not be in contact with the liner system.
(2) A description of the soils to be used for daily, intermediate and final cover, and facility construction, including chemical description, texture, laboratory particle size analyses and quantity. Cross sections of the borrow pits within the proposed permit area shall be included.
(b) An application for a Class III landfill shall contain:
(1) A description of the soils within the proposed permit area and adjacent area down to the bedrock, including for each soil horizon, depth, matrix color, texture, structure, consistency, degree of mottling, mottling colors and laboratory particle size analyses.
(2) The depth to the seasonal high water table within the proposed permit area and adjacent area to demonstrate that the seasonal high water table will not be in contact with the liner system.
(3) A description of the soils to be used for daily, intermediate and final cover, attenuating soil base and facility construction, including texture, chemical description, laboratory particle size analyses and quantity. Cross sections of the borrow pits within the proposed permit area shall be included.
(c) In preparing the description of soils and elevations, the applicant shall do the following:
(1) Base the description on a sufficient number of pits, excavations and samples to allow an accurate characterization of the soils in the proposed permit area and adjacent area and each onsite and offsite borrow area.
(2) Use the following soil classification systems:
(i) For daily, intermediate and final cover, and for attenuating soil, if applicable, the United States Department of Agriculture Soil Classification System.
(ii) For the liner system, site construction and other noncover uses, the Unified Soil Classification System.
(3) Conduct required laboratory particle size analysis according to ASTM D422 (Standard Method for Particle-Size Analysis of Soils) or another analytical method approved in writing by the Department prior to the analyses.
