The Department of Environmental Quality gives notice of the opening of a rulemaking docket concerning amendments that would add a new Article 7 on Engineering Controls. These proposed rules would provide details on how to implement the provisions of A.R.S. § 49-152.01, which specify requirements for an engineering control plan and for financial assurance mechanisms that are intended to cover the costs of maintaining and restoring an engineering control. http://www.azsos.gov/public_services/Register/2008/13/docket.pdf p. 897.
