FAQ - Class V Shallow Wells

What is "Authorized by rule"?

1. "Authorized by rule" means that an injection well may be operated without a permit as long as the owners or operators:

   1. Submit inventory information to their permitting authority and verify that they are authorized (allowed) to inject. The permitting authority will review the information to be sure that the well will not endanger a USDW.

   2. Operate the wells in a way that does not endanger USDWs. The permitting authority will explain any specific requirements.

   3. Properly close their Class V well when it is no longer being used. The well should be closed in a way that prevents movement of any contaminated fluids into USDWs.
