Stormwater Topic - Project in Carroll County Maryland

Stormwater Topic - Project in Carroll County Maryland

Stormwater Topic - Project in Carroll County Maryland

Interesting piece of correspondence I received about a "hot spot" (EPA terminology)for a storm water design for subsurface infiltration (under parking lot)where the only water quality pre treatment is a single inverted elbow, in one of three online catch basins then discharged underground. This is a single industrial use land development proposed and surrounded entirely (without exception) by single family homes dependent on well water for potable supply.

Apparently Carroll County waived the requirement to determine the seasonal high water table, for the infiltration system, as its not documented.

The rest is included in this letter - those consultants who might work in MD, or really any EPA regulated hot spot land use might be interested in the reply. I offered my 2-cents to the sender - which were essentially, page 2.39 of the Maryland Stormwater Design Manual states oil/grit separators cannot be used for stand alone water quality treatment and a hot spot is a land use, and its regulatory differentiation isn't based upon whether or not there is a roof over it or not.

I would appreciate additional comments as they may be helpful for a response.
