037-1 Wyo. Code R. § 1-1
(a) The State Engineer, having general supervision of the waters of the state, is authorized under Section 41-3-909 of the Wyoming Statutes to establish standards for construction of water wells to protect the use of the state's ground water resources. The enactment of federal and state environmental quality law and fostering of safe and clean water policy has prompted enhanced well head protection measures against contamination of ground water resources.
(b) Every well constructed or repaired with a withdrawal of well casing after the adoption of these standards must comply with them. Any deviation from these standards must be approved in writing by the State Engineer or his designee.
(c) It is the joint responsibility of the drilling and/or pump contractor(s) and well owners(s) to comply with these standards. Further, the well owner(s) must maintain a well in a condition so that it does not contribute to contamination (pollution) of the ground water supply.
(d) If compliance with these Water Well Minimum Construction Standards will not result in a well that is sufficiently sealed from either surface or subsurface contamination, then the drilling and/or pump contractor(s) and well owner(s) must use additional safeguards to protect the ground water supply and its users.
(e) Any waiver or variance to these Water Well Minimum Construction Standards can only be obtained by applying for the waiver or variance to the State Engineer in writing. The waiver or variance application shall state the nature of the waiver or variance and the reasons why the waiver or variance will not result in a well that will have a detrimental effect on the ground water resource.
(f) Other state and local regulations pertaining to well drilling and construction, ground water protection, and water quality regulations may exist that are either more stringent than these rules or that apply to a specific situation. It is the well driller's responsibility to understand and apply other regulations as applicable.
(g) Well owners and drillers are advised that local zoning ordinances or county board of health requirements may limit or restrict the actual well location, construction, and/or relationship to property/structure boundaries and existing or proposed concentrated sources of pollution or contamination such as septic tanks, drain fields, sewer lines, stock corrals, feed lots, etc., beyond the requirements of these standards.
(h) Well owners and drillers are advised that standards developed under Wyoming State Law, Title 37, Chapter 12, Article 3 (Damage to Underground Public Utility Facilities) apply.
(i) Well owners and drillers are advised that the State Engineer's Office maintains reporting requirements with regard to certain stages of well completion. These requirements are addressed in the Wyoming State Engineer's Office Part II Rules.
