Components meeting the specifications of design (1)(a) or (1)(b) as identified in the appendix to this rule.
(b) A vegetative layer, consisting of soil and vegetation, placed on top of the soil barrier layer. The soil shall be of sufficient thickness and fertility to support its vegetation and to protect the soil barrier layer from damage due to root penetration, and for facilities For a facility with disposed waste generally having a permeability greater less than 1 x 10-5 cm/sec, design (1)(a), (1)(b), or (2) as identified in the appendix to this rule the soil shall be of a thickness such that the top of the recompacted soil barrier layer lies below the local frost depth.

Comparable materials and/or thicknesses for the soil barrier layer and soil vegetative layer may be used if approved by the director.

The owner or operator shall grade all land surfaces as necessary to prevent ponding of water where residual waste IMW has been placed and institute measures to control erosion.

[Comment: The minimum slope standard in rule 3745-30-07 of the Administrative Code is a design standard. For closure certification, it is not necessary to regrade the site if there is not a ponding problem, even if the slope no longer meets the design in the closure/post-closure plan.]

(5) Design, installation, and maintenance of a ground-water monitoring system in accordance with rule 3745-30-08 of the Administrative Code, if not in place.
(6) The owner or operator shall record A notation on the plat and deed to the industrial landfill or residual waste landfill facility property, or on some other instrument which is normally examined during title search, that will in perpetuity notify any potential purchaser of the property, a . The notation describing shall be recorded by the owner or operator and describe the impacted acreage, exact location, depth, volume, and nature of the residual waste IMW deposited in the industrial landfill or residual waste landfill facility.
(7) Continue to comply Continued compliance with rule 3745-30-14 of the Administrative Code and all monitoring and reporting activities required during the operating life of the industrial landfill or residual solid waste landfill facility until the closure certification is submitted and the post-closure care period begins.
(G) Final closure activities shall be completed not later than one year after final receipt of residual waste in the residual waste landfill facility after any of the occurrences in paragraph (C) of this rule unless an alternate alternative schedule has been approved authorized by The director Ohio EPA.
