PERMIT CONDITIONS 

A. EFFECT OF PERMIT 

The permittee is allowed to engage in Class VI activities in accordance with the conditions of 

this permit. Notwithstanding any other provisions of this permit, the permittee authorized by this 

permit shall not construct, operate, maintain, convert, plug, abandon, or conduct any other 

injection activity in a manner that allows the movement of injection, annulus or formation fluids 

into underground sources of drinking water (USDWs) or any unauthorized zones. The objective 

of this permit is to prevent the movement of fluids into or between USDWs or into any 

unauthorized zones consistent with the requirements at 40 CFR 146.86(a). Any underground 

injection activity not specifically authorized in this permit is prohibited. For purposes of 

enforcement, compliance with this permit during its term constitutes compliance with Part C of 

the Safe Drinking Water Act (SDWA). Such compliance does not constitute a defense to any 

action brought under Section 1431 of the SDWA or any other common or statutory law other 

than Part C of the SDWA. Issuance of this permit does not convey property rights of any sort or 

any exclusive privilege; nor does it authorize any injury to persons or property, any invasion of 

other private rights, or any infringement of State or local laws or regulations. Nothing in this 

permit shall be construed to relieve the permittee of any duties under applicable regulations.
