Latest version.
  • A.  1.  The Department shall not approve any  sludge management plan or issue any permit for the land application of sludge which contains heavy metal concentrations significantly above concentration ranges normal to sludges with demonstrated effectiveness on Oklahoma soils as determined by the Department.  Rules promulgated by the Board for applications for sludge management plans and permits shall require a study of the effects of the sludge on the various types of soils and crops found at the location of the proposed sludge application site.  Such study shall encompass the effects of the sludge on the soils and crops during four (4) growing seasons.

    2.  Any municipality having a sludge management plan approved prior to May 25, 1992, for the land application of sludge containing heavy metal concentrations significantly above acceptable concentration ranges may discontinue such land application of the sludge or shall develop a corrective action plan containing a schedule of compliance for reducing the heavy metal concentration to an acceptable range.  The municipality shall submit the corrective action plan to the Department for approval.  If the Department  disapproves of the plan or the municipality fails to comply with the plan so approved, the Department may require that any such land applications of sludge by the municipality be discontinued pursuant to Article II of the Administrative Procedures Act.

    B.  For developing statewide criteria for application of sludge which contains heavy metal concentrations significantly above concentration ranges normal to sludge, the Department shall utilize a comprehensive study of the potential adverse effects of such sludge on the soils of this state completed by a qualified research institute familiar with the crops and soils of this state.  Such study shall be completed by September 1, 1996, and a report of the findings shall be delivered to the Governor, the President Pro Tempore of the Senate, the Speaker of the House of Representatives and the Executive Director no later than September 1, 1996.
