AZ HB2613

Amends Arizona Revised Statutes Section 49-286 regarding mitigation of nonhazardous releases affecting drinking water sources.

Changes the phrase "non-hazardous" to "nonhazardous" for consistency in terminology.

Replaces the vague reference "the effective date of this chapter" with the specific date "August 13, 1986" to clarify when substances must have been disposed to trigger mitigation obligations.

Maintains the director's authority to order responsible parties to implement mitigation measures including alternative water supplies, blending, treatment, or other mutually agreed measures.

Preserves the requirement that the director balance public benefits against costs and select the least costly alternative when multiple options exist.
