What is the maximum diameter of a clear water pipe through a silt fence?

The maximum diameter of a clear water pipe through a silt fence is 12 inches. This specification is important because it helps manage sediment and water effectively in construction and land-disturbing activities. The purpose of the silt fence is to control sediment runoff, and allowing a pipe of this maximum diameter ensures that there can be a controlled discharge of clear water without compromising the integrity of the sediment barrier.

Larger pipes would potentially allow for greater water flow, which could undermine the fence's ability to filter sediments effectively, leading to increased sedimentation in nearby water bodies. Therefore, adhering to this maximum diameter helps maintain environmental protection practices as outlined in Maryland's Erosion and Sediment Control Guidelines.
