Section 035. 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 mus t be completed and filed with the director on a form approved by the department accompanied by a filing fee a s specified in Section 42-3905(1), Idaho Code. Applications proposing to inject recycled water derived from municipa l 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 industria l wastewater sources unless a permit has been issued by the Director. An application for permit must be completed an d 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 othe r 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. Application s proposing to inject recycled water derived from municipal or industrial wastewater sources must also adhere to al l applicable IDEQ rules and permitting requirements. (7-1-25) 03. Application Information Required. An applicant must submit the following information to th e Director for all injection wells to be authorized by permit, unless the Director determines that it is not needed i n 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 informatio n to demonstrate that the proposed or existing injection well will not endanger a USDW. The Director will not complet e the processing of an application for which additional information has been requested until such time as the additiona l information is supplied. The Director may return any incomplete application and will not process such applicatio n until such time as the application is received in complete form. Additional information may include, but is not limite d to the following items: (7-1-25) a
