SB 1116: groundwater model; receipt; written findings

Sponsor: Senator Dunn, LD 25

Committee on Natural Resources, Energy & Water

Overview

Outlines notification and time frame requirements for the Director of the Arizona Department of Water Resources (Director) as it pertains to submitted alternative groundwater models.

History

Demonstration of Assured Water Supply

An applicant for a certificate of assured water supply is required to provide a copy of a hydrological study if groundwater resources are intended to be used as a part of the supply. The hydrological study must demonstrate an assured supply of groundwater exists for the proposed use by the applicant (A.R.S. § 45-577).

Groundwater Modeling

Groundwater models serve as a representation of the groundwater within a given aquifer or area of an aquifer that is evaluated. These models evaluate current conditions within the aquifer and can be used to understand projected pumping rates, recharge, boundary conditions and impacts of water use (ADWR).

Provisions

1. Requires the Director to provide written notification of receipt to a person who submits an alternative groundwater model, within five days of receiving the alternative model. (Sec. 1)

2. Requires the Director to provide written response to the applicant within 60 days of receipt of the alternative model the following:

a) whether ADWR accepts the overall findings of the alternative groundwater model;

b) whether the director accepts or denies each of the specific findings of the alternative groundwater model; and

c) the rationale for the rejection of any of the findings of the alternative groundwater model. (Sec. 1)
