(4) a regulation;
that is more stringent than or exceeds in any manner the requirements of the department of environmental management's construction stormwater general permit, including financial assurances and any post-construction drainage reports.
(c) If a law, rule, ordinance, or regulation violates subsection (b):
(1) the law, rule, ordinance, or regulation is void; and
(2) the unit in violation of subsection (b) shall continue to discharge its duties under the department of environmental management's construction stormwater general permit program, if any.
(d) If a land disturbing activity would result in the disturbance of less than one (1) acre of total land area and is not part of a larger common plan of development or sale, a unit or the department of environmental management may take the following actions:
(1) If a person conducting a land disturbing activity fails to control sediment or dust from leaving the site, issue a written warning to the person with respect to the sediment or dust.
