(a) Erosion and sediment control practices shall be constructed or installed before land disturbing construction activities begin in accordance with the erosion and sediment control plan developed in S. 08* (2).
(b) Erosion and sediment control practices shall be maintained until final stabilization.
(c) Final stabilization activity shall commence when land disturbing activities cease and final grade has been reached on any portion of the site.
(d) Temporary stabilization activity shall commence when land disturbing activities have temporarily ceased and will not resume for a period exceeding 14 calendar days.
(e) BMPs that are no longer necessary for erosion and sediment control shall be removed by the responsible party.
