12.2.a.4.B. The operator has provided irrevocable financial assurances in a form satisfactory to the Secretary through a contract or other mechanism enforceable under provisions of law, such as delineated in subsection 11.3 of this rule, adequate to provide for long term treatment of the drainage as required by the federal Clean Water Act at 33 U.S.C 1251et seq., the West Virginia Water Pollution Control Act at § 22-11-1et seq. of this code and the operator's National Pollutant Discharge Elimination System permit issued under 47 CSR 30. Default on a treatment obligation under this paragraph will subject the operator to penalties and sanctions, including permit blocking. In order to make this demonstration, the applicant shall address, at a minimum, the current and projected quantity and quality of drainage to be treated, the anticipated duration of treatment, the estimated capital and operating cost of the treatment facility, and the calculations that demonstrate the adequacy of the remaining bond or other financial assurance.
