Class V Injection Well Requirements

01. Permit Required for Class V Deep Injection Wells. No person shall construct, modify, maintain, or use a Class V deep injection well unless a permit has been issued by the Director. An application for permit must be completed and filed with the director on a form approved by the department accompanied by a filing fee as specified in Section 42-3905(1), Idaho Code. Applications proposing to inject recycled water derived from municipal or industrial wastewater sources must also adhere to all applicable IDEQ rules and permitting requirements. (7-1-25) 02. Permit Requirements for Class V Shallow Injection Wells. No person shall construct, modify, maintain, or use a Class V shallow injection well to inject recycled water derived from municipal or industrial wastewater sources unless a permit has been issued by the Director. An application for permit must be completed and filed with the director on a form approved by the department accompanied by a filing fee as specified in Section 42- 3905(1), Idaho Code. An application for permit may be required for the construction, modification, or use of all other shallow injection wells if the Director determines that the injection could result in unreasonable contamination of a USDW or cause a violation of Ground Water Quality Standards that would affect a beneficial use. Applications proposing to inject recycled water derived from municipal or industrial wastewater sources must also adhere to all applicable IDEQ rules and permitting requirements. (7-1-25) 03. Application Information Required. An applicant must submit the following information to the Director for all injection wells to be authorized by permit, unless the Director determines that it is not needed in whole or in part, and issues a written waiver to the applicant: (7-1-25) a. Facility name and location; (7-1-25) b. Name, address and phone number of the well operator; (7-1-25) c. Class, subclass and function of the injection well (see Section 020); (7-1-25) d.

(7-1-25) 04. Additional Information. The Director may require an applicant to submit additional information to demonstrate that the proposed or existing injection well will not endanger a USDW. The Director will not complete the processing of an application for which additional information has been requested until such time as the additional information is supplied. The Director may return any incomplete application and will not process such application until such time as the application is received in complete form. Additional information may include, but is not limited to the following items: (7-1-25) a. A topographic map showing locations of the following within a two (2) mile radius of the injection well: (7-1-25) i. All wells producing water; (7-1-25) ii. All exploratory and test wells; (7-1-25) iii. All other injection wells; (7-1-25) iv. Surface waters (including man-made impoundments, canals and ditches); (7-1-25) v. Mines and quarries; (7-1-25) vi. Residences; (7-1-25) vii. Roads; (7-1-25) viii. Bedrock outcrops; and (7-1-25) ix. Faults and fractures. (7-1-25) b. Additional maps or aerial photographs of suitable scale to accurately depict the following: (7-1-25) i. Location and surface elevation of the injection well described in this permit; (7-1-25) IDAHO ADMINISTRATIVE CODE IDAPA 37.03.03 – Rules & Minimum Standards Department of Water Resources for the Construction & Use of Injection Wells Section 050 Page 13 ii.
