(a) Quantity summaries.
- (1) The narrative shall include a tabulation of excavation and material quantities required to construct the facility as designed.
- (2) The tabulation descriptions shall correlate with plan cross sections, e.g., clay liner, barrier layer, etc., and list all off-site borrow areas necessary to provide an adequate quantity and quality of the various materials.
- (3) The purpose of the tabulation shall be to demonstrate that the site contains sufficient quantities and types of material to construct the facility or where deficiencies or shortfalls will be obtained.
- (4) This section sets forth the minimum information to be provided.
(b) Tabulated items.
- (1) Excavation quantities along with the anticipated amounts that will be suitable for clay liner and final cover construction shall be provided along with the amount of material available for daily and intermediate cover.
- (2) Also included shall be the quantities required for clay liner and final cover construction, along with gross and net airspace figures and an estimation of the amounts of daily and intermediate cover material that will be required.
(c) Material stockpiling.
- (1) In the event that the phasing of operations will require long-term (generally greater than one (1) year) stockpiling of materials, this shall be discussed fully in the operations narrative and the plans shall designate material stockpiling locations.
- (2) Best management practices in accordance with 8 CAR § 60-411(h) shall be implemented at all stockpile locations and general procedures for the temporary stockpiling of soil required by routine operations shall be discussed in the operating narrative.
- (d) Deficiencies. In the event that the amount of excavated material does not yield sufficient quantities of any material types, the narrative shall describe the deficiency and where the additional material will be obtained.
(e) Borrow areas.
- (1) In the event that the facility proposes to obtain "borrow" material from a designated source outside of the disposal area for liner or cover construction, daily operations, or any other use, the narrative shall include a description of the methods that will be used to control erosion at the borrow area.
- (2) Best management practices as described in 8 CAR § 60-411(h) shall be implemented on an ongoing basis at borrow areas.
(f) Borrow areas reclamation.
- (1) All borrow areas owned or leased by the owner or operator shall be reclaimed in accordance with the Arkansas Open-Cut Mining and Land Reclamation Code, 15 CAR pt. 231, of the Arkansas Pollution Control and Ecology Commission and the requirements of this subsection.
(2) Final reclamation may include, but may not be limited to:
- (A) Elimination of vertical or near vertical cut banks (high walls);
- (B) Construction of final side slopes to three horizontal to one vertical (3:1) or flatter;
- (C) Grading the site to properly drain; and
- (D) Establishing permanent vegetation cover to fully stabilize the site.
- (3) The Director of the Division of Environmental Quality may approve alternative borrow reclamation plans depending upon site topography, soil types and conditions, site geology, and the intended land use of the site following reclamation.
