What are BMPs in stormwater?
Today, storm- water management includes controlling flooding, reducing erosion and improving water quality. This can be accomplished by implementing what are known as Best Management Practices (BMPs). BMPs are structural, vegetative or managerial practices used to treat, prevent or reduce water pollution.
What does a stormwater manager do?
So, how does stormwater management help? In urban and developed areas, impervious surfaces such as pavement and roofs prevent precipitation from naturally soaking into the ground. Detaining stormwater and removing pollutants is the primary purpose of stormwater management.
What is stormwater management construction?
Stormwater management in construction is critical, with the primary goal in both commercial and DIY projects being to prevent building site by-products from entering stormwater drains. Failure to plan can cause costly delays to your project.
Are BMPs effective?
By effectively using BMPs, you have a very high likelihood of preventing and controlling that polluted runoff, before it can reach a creek, pond, or wetland. And if you prevent or control nonpoint source pollution, you will most likely stay in compliance with the various water quality regulations for North Carolina.
What are BMPs examples?
Structural BMPs are measures that control or manage stormwater runoff and drainage. Examples of structural BMPs include swales, dikes, ponds, filtration devices, and infiltration basins.
How do stormwater management ponds work?
These ponds are designed to capture and hold stormwater– for a while. Wet ponds slow down the water, which helps settle out some of the sediments and allows some pollutants to be removed or degraded by natural environmental processes. This helps return cleaner water to our rivers, creeks, and streams.
How do construction sites affect water quality?
Sediment pollution from construction sites contaminates drinking water, impacts recreational waters, diminishes commercial fisheries and increases the risk of flood damage. Dirty runoff from construction sites can also carry other pollutants into waterways.
What does EPA mean in construction?
get Clean Water Act (CWA) permit coverage for discharge of storm water runoff from your construction site. Storm water general permits are issued through the U.S. Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) pro- gram or the state NPDES permitting authority.
Why are BMPs important?
BMPs provide a science-based approach to protecting water quality from potential risks. Specifically, during a renovation or grow-in period, BMPs protect water quality while the site is most vulnerable to soil erosion.
What is the New Jersey stormwater best management practices manual?
The New Jersey Stormwater Best Management Practices Manual (BMP manual) is developed to provide guidance to address the standards in the Stormwater Management Rules, N.J.A.C. 7:8. The BMP manual provides examples of ways to meet the standards contained in the rule. The methods referenced in the BMP manual are one way of achieving the standards.
How are dry wells used in New Jersey?
dry well is through infiltration into the subsoil, although they are required to have an overflow for diverting runoff generated by larger storms. Dry wells may be used to meet the groundwater recharge design standard at N.J.A.C. 7:8-5.4(b)(1). Additionally, dry wells may be used to reduce the stormwater
What do you need to know about the BMP manual?
The BMP manual provides examples of ways to meet the standards contained in the rule. The methods referenced in the BMP manual are one way of achieving the standards. An applicant is welcome to demonstrate that other proposed management practices will also achieve the standards established in the rules.
Where can I find information on stormwater runoff?
Welcome to NJDEP’s stormwater web site for stormwater management professionals and permittees. Here you’ll find links to technical information, guidance materials, forms, and applications. General guidance and resources regarding stormwater runoff are also available at www.cleanwaternj.org.
