 The revised sediment and stormwater regulations will address runoff from the most frequent rainfall event; stormwater volume control; stormwater management for redevelopment; and plan approvals for construction of residential, utility and poultry house projects. 

 In addition to addressing legislative actions, the revised regulations include simplified criteria for the approval of smaller, less impactful projects.  The revised regulations include standards and specifications for each of 17 post-construction stormwater management best management practices (BMPs), and expand the section in the regulations on stormwater offsets to include details regarding fees-in-lieu, banking and stormwater management offset districts.
