Section R12-15-850. Evaluation of Notices of Intention to Drill; Notifi- cation of Registered Site Locations; Vertical Cross-Contamina- tion Evaluation

A.      The Director shall, upon receipt of a complete and correct notice of intention to drill form required under A.R.S. § 45- 596, or upon receipt of an application for a permit under

A.R.S. § 45-597 through 45-599, identify whether the pro- posed well will be drilled within a groundwater basin or sub- basin in which there exists a site listed on the registry established under A.R.S. § 49-287.01(D). If the proposed well is situated within such a groundwater basin or subbasin, the Director shall notify the applicant and the authorized well drilling contractor in writing of the existence of the site and shall enclose a map indicating the boundaries of all listed sites within the groundwater basin or subbasin. The notification let- ter shall include the name, address, and telephone number of a Department contact person, along with a reference to the pro- vision in R12-15-851 that requires the applicant to notify the Department in advance of the date drilling of the well will commence. The Department shall also specify in the notifica- tion letter whether the applicant is subject to the requirements of R12-15-851.

B.       The Director shall, upon receipt of a complete and correct notice of intention to drill form required under A.R.S. § 45- 596, or upon receipt of an application for a permit under

A.R.S. § 45-597 through 45-599, identify whether the pro- posed well will be drilled within an area where existing or anticipated future groundwater contamination presents a risk of vertical cross-contamination, as defined in A.R.S. § 49- 281(15). If the Director determines that the proposed well will be drilled in such an area, and if the Director finds that the requirements of R12-15-811 are insufficient to prevent the risk of vertical cross-contamination, the Director shall establish site-specific requirements pursuant to R12-15-812 and R12- 15-821.
