Any person engaging in any land disturbing activity shall be encouraged to comply with the standards for erosion and sediment control established by the district, except those land disturbing activities relating to surface mining permitted under Chapter 4 of the Illinois Pollution Control Board regulations. When proposed land disturbing activities are to be performed on State land or by or on behalf of a State agency, the person engaging in the activities may elect to comply with standards established by the Department. If land disturbing activities involve land in more than one district, the person engaging in the activities may elect to comply with standards established by each district or standards established by the Department. He shall notify, in writing, each district involved and the Department concerning the standards he elects to comply with.
Upon request, the district, or the Department, as the case may be, shall make available to any person engaged in a land disturbing activity, adequate information and technical assistance to enable that person to comply with the standards of the district or the Department.
The program adopted by each district shall provide for the sharing by the district of part of the cost of enduring erosion and sediment control devices, structures and practices and shall specify the cost-sharing ratios which shall apply to various types of enduring erosion and sediment control devices, structures and practices in that district. The program adopted by the Department shall, in the same manner, provide for cost-sharing by the Department with respect to enduring erosion and sediment control devices, structures and practices when required in relation to a land disturbing activity involving land in more than one district.
When a land disturbing activity does not comply with district or Department standards, the district or the Department, as the case may be, shall suggest such modifications, terms and conditions as will enable the person engaged in the land disturbing activity to comply with the standards.
