This section was designed to provide information on the fundamentals of stormwater management. In this section, one will be able to learn the essentials concepts needed to understand and implement SWPPPs (Stormwater Pollution Prevention Plan) and BMPs (Best Management Practices).
Understanding the science and terms behind approved SWPPPs is crucial to ensure that stormwater discharges remain in compliance with the NPDES Permitting Program. For instance, there are many terms (i.e., larger common plans, waters of the state, and green infrastructure) that are loosely thrown around without their full meaning being grasped.Improper usage and understandings of these fundamental concepts will lead to SWPPP failures that may cause irreversible, adverse impacts to downstream ecosystems. It is highly suggested that all those in association with the land disturbing activity fully understand the fundamentals behind the developed SWPPP.
LIDsWhen used as properly designed, Low Impact Development BMPs can significantly reduce the runoff loading by targeting runoff as close to its source as possible.
Soil ImportanceThe type and state of the soil located within the land disturbance activity can drastically affect infiltration rates, peak discharges, and water quality BMPs.
Information provided within this section may also help direct the design engineer or SWPPP preparer towards a more efficient and sound stormwater management plan. S.C. DHEC also recommends that outside resources be consultant in addition to the subsiding pages while developing site specific SWPPPS..
