25 Pa. Code § 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.
