When are storm water discharges regulated as injection wells?
Storm water drainage wells (usually considered a class V injection well) are typically shallow disposal wells designed to place storm water below the land surface. By EPA definition, a Class V injection well is any hole that is deeper than its widest surface dimension or any subsurface fluid distribution system that releases fluids underground. Storm water management BMP’s that include subsurface infiltration must comply with the EPA Underground Injection Control program.
