Erosion & Sediment Control




Rule 5- Construction/Land Disturbance Storm Water Permitting


The requirements of Rule 5 now apply to all persons who are involved in construction activity (which includes clearing, grading, excavation and other land disturbing activities) that results in the disturbance of one (1) acre or more of total land area. If the land disturbing activity results in the disturbance of less than one (1) acre of total land area, but is part of a larger common plan of development or sale, the project is still subject to storm water permitting.

Erosion Control & Sediment Control

The Marion County Soil and Water Conservation District’s (SWCD’s) primary responsibility under state law is to promote the wise use of soil, water, and related natural resources.  Soil erosion, and the resulting sedimentation, is one of our main resource concerns.


Can Sediment Pollute?

Sediment is the #1 pollutant (by volume) in Indiana waterways! Different from a smokestack or sewer pipe (point source pollution), sediment is usually deposited over a wide area, which is why it is known as a non-point source pollutant.  In addition, sediment can have many other types of pollution attached to its soil particles.  Learn more about non-point source pollution (NPS)  by checking out the Environmental Protection Agency’s NPS web pages at: .  NPS can be addressed with the use of Best Management Practices (BMPs), which include silt fences around the perimeter of the land-disturbing activity, leaving a few feet of vegetation along the outside edge of the construction site for a “filter strip” or seeding the area immediately.


Once installed, silt fences must
be maintained

 This runoff water is  brown
because it is carrying sediment
 Potentially severe erosion sites
require “hard” or stone BMPs.
