  Subpart G_Requirements for Owners and Operators of Class V Injection 
                                  Wells
 
Sec.  144.82  What must I do to protect underground sources of drinking 
water?

    If you own or operate any type of Class V well, the regulations 
below require that you cannot allow movement of fluid into USDWs that 
might cause endangerment, you must comply with other Federal UIC 
requirements in 40 CFR parts 144 through 147, and you must comply with 
any other measures required by your State or EPA Regional Office UIC 
Program to protect USDWs, and you must properly close your well when you 
are through using it. You also must submit basic information about your 
well, as described in Sec.  144.83.
    (a) Prohibition of fluid movement. (1) As described in Sec.  
144.12(a), your injection activity cannot allow the movement of fluid 
containing any contaminant into USDWs, if the presence of that 
contaminant may cause a violation of the primary drinking water 
standards under 40 CFR part 141, other health based standards, or may 
otherwise adversely affect the health of persons. This prohibition 
applies to your well construction, operation, maintenance, conversion, 
plugging, closure, or any other injection activity.
    (2) If the Director of the UIC Program in your State or EPA Region 
learns that your injection activity may endanger USDWs, he or she may 
require you to close your well, require you to get a permit, or require 
other actions listed in Sec.  144.12(c), (d), or (e).
    (b) Closure requirements. You must close the well in a manner that 
complies with the above prohibition of fluid movement. Also, you must 
dispose or otherwise manage any soil, gravel, sludge, liquids, or other 
materials removed from or adjacent to your well in accordance with all 
applicable

Federal, State, and local regulations and requirements.
    (c) Other requirements in Parts 144 through 147. Beyond this 
subpart, you are subject to other UIC Program requirements in 40 CFR 
parts 144 through 147. While most of the relevant requirements are 
repeated or referenced in this subpart for convenience, you need to read 
these other parts to understand the entire UIC Program.
    (d) Other State or EPA requirements. 40 CFR parts 144 through 147 
define minimum Federal UIC requirements. EPA Regional Offices 
administering the UIC Program have the flexibility to establish 
additional or more stringent requirements based on the authorities in 
parts 144 through 147, if believed to be necessary to protect USDWs. 
States can have their own authorities to establish additional or more 
stringent requirements if needed to protect USDWs. You must comply with 
these additional requirements, if any exist in your area. Contact the 
UIC Program Director in your State or EPA Region to learn more.
