ENVIRONMENTAL COMPLIANCE STORMWATER MANAGEMENT:

WHAT IS STORMWATER?
“Stormwater” is a term used to describe the water that comes from various precipitation events or snowmelt. Stormwater that does not soak into the ground will become runoff, which will either flow into surface waterways or be channeled into storm sewers.

WHY IS STORMWATER DESIGN IMPORTANT?
Stormwater is of concern for two main reasons. One is related to the amount of stormwater runoff. The other is related to potential contaminants that the water is carrying which may pollute our lakes, rivers, and streams. 

Impervious surfaces, such as parking lots, roads, and buildings, do not allow rain to infiltrate into the ground. Due to this, additional surface runoff is generated by land development. This runoff can cause the erosion of watercourses, streams, and rivers, as well as potentially cause flooding of downstream properties, roads, and sewers.  

Because the water is flushed out of the watershed during the storm event, little will infiltrate the soil, replenish groundwater, or supply streams with base flow during dry periods.

WHAT IS A STORMWATER DESIGN REPORT?
The Stormwater Design Report contains a description of the site and surrounding watershed. A comparison of the site is made between pre-development and post-development conditions. The report will include anticipated flows from proposed development, and calculations to support the required runoff Best Management Practices (BMPs). BMPs such as detention ponds, infiltration basins, rain gardens, and subsurface seepage pits are proposed to reduce runoff and promote stormwater management.  This is typically submitted to the municipality with either the Subdivision or Land Development plans. A municipality may require a separate Stormwater Plan. This portion of the project must be completed by a Professional Land Surveyor or Professional Engineer.

EROSION & SEDIMENTATION CONTROL:

WHAT IS EROSION & SEDIMENTATION?
While erosion is a natural process, in many places it can be increased by human land use. Poor land use practices can include deforestation, overgrazing, unmanaged construction activity, and other development. With a lack of vegetation to protect the soil beneath, wind and water can readily erode and transport soil into nearby waterways, clogging them with fine sediments known as silt, clay, or colloids. This is called sedimentation.

These sediments settle out of water or air into layers on a surface. Runoff from bare soil may also contain chemicals, heavy metals, and other pollutants that may be washed into nearby waters. Much of the total soil erosion results from activities such as construction, logging, agriculture, and natural events. However, improved land use practices can reduce erosion. Using techniques like contour farming, terrace-building, tree planting, and properly installed & maintained control BMPs such as sediment basins, silt fence, erosion matting, compost socks & rock filters implemented during construction and earthmoving activities, may greatly reduce the damages from erosion.

WHEN IS AN E&SC PLAN REQUIRED?
According to the Pennsylvania Department of Environmental Protection (PA DEP), “development of an erosion and sedimentation control plan is required for all earth disturbances of 5,000 square feet or greater, earth disturbances in High Quality or Exceptional Value watersheds, or if other DEP permits require it.”

Projects which will have less than 5,000 square feet of earth disturbance are required to develop, implement, and maintain erosion and sedimentation control Best Management Practices (BMPs). They are, however, exempt from having the associated Conservation District review the plan. Any project which disturbs 1 to 5 acres and which also has a discharge to waters of the Commonwealth, will usually require a National Pullutant Discharge Elimination System (NPDES) permit for stormwater discharges associated with construction activities.Any project which disturbs more than 5 acres will require a NPDES permit for stormwater discharges associated with construction activities, as well as an approved erosion & sedimentation control plan.For more information, visit your county’s conservation district or state’s Department of Environmental Protection website.
