| (a) In the application, the owner or operator shall
submit documentation demonstrating compliance with applicable design
criteria in Subchapter F of this chapter (relating to Design Criteria).
(b) For new or laterally expanding coal combustion
residuals landfills and surface impoundments, the owner or operator
shall submit subsurface soil information. A sufficient number of borings
shall be performed to establish the subsurface stratigraphy and determine
geotechnical properties beneath the unit. The borings must be to a
sufficient depth to identify the uppermost aquifer and any underlying
hydraulically interconnected aquifers. All borings shall be conducted
in accordance with established field exploration methods. The subsurface
soil information must be prepared and certified in accordance with §352.4
of this title (relating to Engineering and Geoscientific Information)
and shall be included with the application. The subsurface soil information
must include:
(1) a description of all borings drilled at the unit
location, to test soils and characterize groundwater;
(2) a unit map drawn to scale showing the surveyed
locations and elevations of the borings;
(3) cross-sections prepared from the borings depicting
the generalized strata at the unit;
(4) boring logs including a description of materials
encountered, including any discontinuities such as fractures, fissures,
slickensides, lenses, or seams;
(5) a description of the geotechnical data and the
geotechnical properties of the subsurface soil materials, including
the suitability of the soils and strata for the intended uses; and
(6) a demonstration that all geotechnical tests were
performed in accordance with industry practice and recognized procedures.
