A
|
This BMP could be designed with or without an infiltration component.
If infiltration is proposed, the site and BMP will be subject to the
testing and other infiltration requirements in this part.
| |
B
|
If this BMP is used to treat the entire Iv, then it is the only
BMP required because of this BMP's superior water quality performance.
| |
C
|
See table below.
| |
D
|
Water quality inlets include such BMPs as oil/water separators,
sediment traps/catch basin sumps, and trash/debris collectors in catch
basins.
