The terms of the corporate guarantee shall provide for the following:
Where a permit apphcation includes two or more of the four major mining categories, the application will delineate the proposed disturbed acres for each category and the site specific per acre bond amount for each category will be calculated in accordance with the provisions of this subsection as if it were a separate permit and the respective bond amount shall be posted for each area of proposed disturbance in that category.
Where active or inactive operations are in compliance with the provisions of subsection 14.15 of this rule and coal extraction operations are completed, or nearly completed, or when the operations are eligible for or have received Phase I bond release, the site specific bond criteria of this subsection shall not apply.
All existing permits for surface mining operations in the four major categories set forth in subdivision 11.5.b of this subsection shall be reviewed by the Secretary and a determination made as to whether or not the surface mining operations are subject to the site specific bonding criteria set forth herein. The determinations shall be made in accordance with the following:
Existing permits in the four major categories described in subdivision 11.5.b of this subsection shall be reviewed by the Secretary at the time of renewal and a determination made as to the adequacy of existing bond and shall not be renewed by the Secretary until the appropriate amount of bond has been posted.
These are shown on the "x" axis of the matrix. Each of these criteria have been assigned a numerical criteria value for calculating the site specific per acre bond amount. The sum of the criteria values do not exceed 5,000, which is the maximum per acre dollar amount of the bond provided for in the Act.
Under each major criteria are listed two or more sub-criteria. These sub-criteria represent readily identifiable and quantifiable elements of a permit application. Each sub-criteria is assigned a numerical constant which when summed equals the numerical value of their respective criteria.
In order to determine the appropriate site specific bond amount for a specific permit, each sub-criteria constant is multiplied by a conversion factor which is displayed on the "y" axis of the matrix. The value of the conversion factors reflects a quantifiable element of the sub-criteria which influences the level of consideration each element must be given in determining reclamation costs or risk. The sum of the converted constants will be the total per acre bond amount for a specific permit.
Approved husbandry practices shall be limited to pest and vermin control, pruning and any reseeding and/or transplanting specifically necessitated by such actions, but shall be normal conservation practices within the region for unmined lands having land uses similar to the approved postmining land use of the area covered by the bond.
