Stormwater Management

What is StormWater Management?

Stormwater is rainwater and melted snow that runs off streets, lawns, farms, and construction and industrial sites. Under natural conditions, stormwater is absorbed into the ground, where it is filtered and ultimately replenishes aquifers or slowly flows through forests and meadows into streams and rivers.

In developed areas, however, impervious surfaces such as pavement and building roofs prevent precipitation from naturally soaking into the ground. Instead, the water runs rapidly into storm drains, sewer systems, and drainage ditches. The resulting rush of stormwater discharge can cause infrastructure damage, downstream flooding, and stream bank erosion. In addition, the bacteria and other pollutants not filtered from stormwater can contaminate streams, rivers, and coastal waters.

Stormwater management addresses these concerns through a variety of techniques, including strategic site design, measures to control the sources of runoff, and thoughtful landscape planning.

The MS4 Program

Understanding the MS4

The following are the various mandated requirements of the MS4:

1. Public Education and Outreach

Distributing educational materials and performing outreach to inform citizens about the impacts polluted storm water runoff discharges can have on water quality.

2. Public Participation/Involvement

Providing opportunities for citizens to participate in program development and implementation, including effectively publicizing public hearings and/or encouraging citizen representatives on a storm water management panel.

3. Illicit Discharge Detection and Elimination

Developing and implementing a plan to detect and eliminate illicit discharges to the storm sewer system (includes developing a system map and informing the community about hazards associated with illegal discharges and improper disposal of waste).

4. Construction Site Runoff Control

Developing, implementing, and enforcing an erosion and sediment control program for construction activities that disturb 1 or more acres of land (controls could include silt fences and temporary storm water detention ponds).

5. Post-Construction Runoff Control

Developing, implementing, and enforcing a program to address discharges of post-construction storm water runoff from new development and redevelopment areas. Applicable controls could include preventative actions such as protecting sensitive areas (e.g., wetlands) or the use of structural BMPs such as grassed swales or porous pavement.

6. Pollution Prevention/Good Housekeeping

Developing and implementing a program with the goal of preventing or reducing pollutant runoff from municipal operations. The program must include municipal staff training on pollution prevention measures and techniques (e.g., regular street sweeping, reduction in the use of pesticides or street salt, or frequent catch-basin cleaning). or its chosen BMPs and measurable goals for each minimum control measure. To help permittees identify the most appropriate BMPs for their programs, EPA will issue a“menu,” of BMPs to serve as guidelines.. NPDES permitting authorities can modify the EPA menu or develop their own list.

Ten Things You Can Do to Prevent Stormwater Runoff Pollution

• Use fertilizers sparingly and sweep up driveways, sidewalks, and gutters
• Never dump anything down storm drains or in streams
• Vegetate bare spots in your yard
• Compost your yard waste
• Use least toxic pesticides, follow labels, and learn how to prevent pest problems
• Direct downspouts away from paved surfaces; consider a rain garden to capture runoff
• Take your car to the car wash instead of washing it in the driveway
• Check your car for leaks and recycle your motor oil
• Pick up after your pet
• Have your septic tank pumped and system inspected regularly

Water Quality Hotlines for Citizens

Citizens can help report violations or problems they notice in their local streams before they cause more damage and pollution. Residents sometimes may be the first to recognize “illicit” discharges dumping into storm sewers or coming out of from storm sewer outfalls.

New stormwater regulations from Pennsylvania’s DEP require that your municipality investigate more thoroughly potential illicit discharges (pollutants) into our streams. You can help by promptly reporting the following events to the authorities listed in the hotline box below. The township’s web site also contains a form for reporting these conditions (put link here). Here are some of the conditions that you should report:

• Sediment leaving a construction site in stormwater (your county conservation district)
• Observed pollution event or pollutants in stream (DEP)
• Clogged or leaking sewer lines (your sewer authority)
• Failing or overflowing sewer effluent from treatment plant (your sewer plant and DEP)
• Spills (DEP spills hotline)
• Illegal dumping activity into water courses (your municipality, DEP)
• Dry weather flows from outfall pipes into streams (72 hours after a rain storm)( your municipality)
• Fish Kills (Fish Commission, DEP)
• Water main breaks (Aqua PA or Chester Water Authority).
• Photos and exact locations are very helpful!
