What is a drainage BMP?
Point BMPs: Practices that capture upstream drainage at a specific location and may use a combination of detention, infiltration, evaporation, settling, and transformation to manage flow and remove pollutants.
How often should BMPs be inspected?
To summarize Table 7-1, devices that include vegetation in a highly engineered system require inspection monthly and after large storm events to catch any problems with flow conveyance or vegetative health before they become serious. All other BMPs should be inspected quarterly and after large storm events.
What is BMP compliance?
BMPs are structural controls that when installed correctly, reduce the amount of storm water discharge as well as improve the quality of the storm water discharge that leaves you site. The following are examples of BMPs: Onsite Ponding Basins. Contractor Washouts. Trackout Control.
What is a BMP report?
Answer: The acronym “BMP” is short for Best Management Practice. In the context of water quality, BMPs are devices and actions that improve or prevent the pollution of urban runoff and stormwater.

A BMP is a method used to prevent or control stormwater runoff and the discharge of pollutants, including sediment, into local waterbodies. Silt fences, inlet protection, and site-stabilization techniques are typical BMPs on a construction site.

What are the two main types of BMPs?
Types of BMPs. Pennsylvania’s Stormwater Best Management Practice Manual divides common stormwater best management practices (BMPs) into two categories: structural or non-structural.
What is a BMP device?
Stormwater treatment BMPs are structural devices used to manage and treat runoff contaminated with pollutants. In some cases, these BMPs can also be used to divert runoff away from areas where pollutants may occur.
Which is an example of BMP?
Also called dry ponds, dry detention basins are a BMP used primarily for controlling water quantity versus quality, as they only confine stormwater for a short amount of time. Here’s how they work: During and immediately following storm events, the basin fills with stormwater runoff.
What is a structural BMP?
A structural stormwater Best Management Practice (BMP) is defined in the MS4 General permit as “a stationary and permanent BMP that is designed, constructed and operated to prevent or reduce the discharge of pollutants in stormwater“.
