How the Safe Drinking Water Act Applies to Class V Wells
At 40 CFR 144, the EPA defines six (6) classes of wells subject to differing Underground Injection Control (or UIC) requirements.
Class V wells are found in every state and are the class most commonly used by industry and small commercial operators. EPA estimates there are 650,000 Class V wells in operation nationwide.These wells are used to inject non-hazardous fluids underground.
What Are Class V Wells?
Class V wells can include:
- Shallow wastewater disposal wells.
- Stormwater wells.
- Agriculture drainage systems.
- Sump and separator systems.
- Drainage or dry-wells.
- Septic systems.
Class V wells are “authorized by rule.” This means that owners and operators of Class V wells may inject certain types of fluids without needing to obtain an individual permit from EPA or their authorized State agency, provided the well owner/operator meets minimum requirements:
Basic EPA Requirements for Class V Wells
- Injected materials can not threaten or endanger USDWs.
- Inventory information must be provided to Federal EPA or State agency before commencing injection. This information must include:
- Facility name and location.
- Name and address of legal contact.
- Ownership of facility.
- Nature and type of injection well(s).
- Operating status of the injection well.
In response to the inventory submission, the State agency (or EPA) will do one of four things:
What Happens Next?
- Determine that you are “authorized by rule” to inject (meaning your well meets the requirements of some other regulatory program, for instance, the stormwater discharge requirements of 40 CFR 122).
- Request you to submit additional information, usually to determine if there is a chance the injected material will negatively impact USDWs.
- Require you to obtain a permit, if there’s a concern that your well will endanger USDWs.
- Require closure of the well, if the presence of the well is a clear threat to USDWs.
Want to know more about Class V wells? EPA has released a twenty-three-volume study,required by a 1997 court case, that looks at twenty-two types of Class V wells and the risks they pose to underground sources of drinking water.

My experience with Lion classes has always been good. Lion Technology always covers the EPA requirements I must follow.
I have over 26 years of environmental compliance experience, and it has been some time since I have attended an environmental regulations workshop. I attended this course as preparation for EHS Audits for my six plants, and it was exactly what I was looking for.

Lion is my preferred trainer for hazmat and DOT.
As always, Lion never disappoints
Lion provided an excellent introduction to environmental regulations, making the transition to a new career as an EHS specialist less daunting of a task. Drinking from a fire hose when the flow of water is lessened, is much more enjoyable!
I really enjoyed this training. Even after years on both sides of the comprehension coin, I find myself still learning! The quality of the delivery exceeded much of the training I have received in the past.
