Filter backwash / EPA Class V injection well
Filter backwash / EPA Class V injection well
(OP)
New here - looking for guidance -
I'm designing a groundwater supply for a small community (50 homes). It includes a filter to remove Fe & Mn. The filters backwash each night into a drainfield (about 100 gal). Solids will settle out in a septic tank.
Question is: Would this be classified as a Class V injection well? What do I need to do if it is?
Sorry if that seems like a dumb question. My research on the subject from EPA has found descriptions of other Class V's, but none that match this situation.

RE: Filter backwash / EPA Class V injection well
Existing residual pits that are being used to dewater drinking water treatment residuals (such as you are proposing) were permitted by rule as described below. You need to contact the state environmental agency where your site is located for guidance as to how they are handling this new program as well as to obtain a permit for your new Class V injection well.
Here is some information for you to review:

Permitting by Rule
• EPA has the authority promulgate permit by rule
provisions
• This provides additional flexibility to grant “general
permits” or authorize injection for broader categories of
injection wells
• Not subject to the limitations applicable to Area Permits
• The permit by rule provision has been used by EPA for most Class V wells and was used to grandfather most existing wells at the creation of the UIC program
