Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 816 - ALTERNATIVE STANDARDS FOR COAL COMBUSTION POWER GENERATING FACILITIES WASTE LANDFILLS › Section 816.510 - Poz-O-Tec Liners and Caps

Current through Register Vol. 48, No. 28, July 12, 2024
Notwithstanding the liner and cap requirements set forth at 35
				Ill. Adm. Code
				811.306,
				811.314
				(solely to the extent that it may preclude Poz-O-Tec materials from being used
				as a landfill cap or liner) and
				811.507(a)(5),
				FGD sludges and coal combustion waste produced by coal combustion power
				generating facilities may be used for liner or cap construction for the
				purposes of Subpart C of Part 811, provided that:
a) These raw FGD sludges and coal combustion
			 wastes have been processed into Poz-O-Tec materials;
b) The permeability of the liner constructed
			 of Poz-O-Tec material is demonstrated to be less than or equal to 1 x
			 10-7 cm/sec after placement and curing based upon a
			 geometric average of the permeability testing results prior to the placement of
			 any waste upon the liner;
c) The
			 Poz-O-Tec material has an unconfined compressive strength of greater than or
			 equal to 150 psi based upon an arithmetic average of the strength testing
			 results obtained in accordance with Section
			 816.530(c)
			 of this Part;
d) The bottom liner
			 has a minimum thickness of three feet but this thickness may be increased as
			 necessary to make the demonstrations required by 35 Ill. Adm. Code 812 or
			 815;
e) The base of the liner is
			 constructed at least five feet above the average historical groundwater
			 table;
f) Only coal combustion
			 wastes and FGD sludges produced from power generating facilities are placed
			 into the landfill;
g) A final cover
			 system is installed in accordance with the requirements of 35 Ill. Adm. Code
			 811.314 except
			 that the low permeability layer of the cap shall consist of Poz-O-Tec materials
			 which are at least three feet thick;
h) The material testing procedures specified
			 in Section
			 816.530
			 are implemented;
i) The landfill is
			 designed, constructed and operated in compliance with all applicable
			 requirements of 35 Ill. Adm. Code 811, 812 and 815;
j) The bottom liner and low permeability
			 layer of the cap are constructed according to a construction quality assurance
			 program in accordance with 35 Ill. Adm. Code 811.Subpart E;
k) An acceptable groundwater impact
			 assessment pursuant to 35 Ill. Adm. Code
			 811.317(b),
			 812.316,
			 813.304,
			 or
			 815.203,
			 as appropriate for the given facility, is submitted to the Agency by the owner
			 or operator;
l) A test liner is
			 constructed by the owner or operator, so that all that remains is the curing of
			 the test liner, before construction of the actual full-scale liner of Poz-O-Tec
			 material may commence, in accordance with 35 Ill. Adm. Code
			 811.507(a)(1)
			 through (4). The test liner must be fully
			 evaluated in accordance with Section
			 816.530
			 and the results must be provided to the Agency. If the test liner evaluation
			 results indicate a failure of the test liner to meet any of the performance
			 standards in this Section, and if the Agency so directs, the user must excavate
			 and properly dispose of all Poz-O-Tec liners at the site, as well as any waste
			 deposited in and around such liners; and
m) Owners or operators using Poz-O-Tec
			 materials in accordance with this Section shall comply with the Illinois
			 Environmental Protection Act [415 ILCS 5/1 ] and 35 Ill. Adm.
			 Code 807, 810, and 811, to the extent those provisions are not otherwise
			 addressed herein.
