Quality Assurance Manual
The Quality Assurance Manual (QAM) is required by ADOT's Permit. The purpose of the QAM is to document ADOT policies and procedures ensuring adequate quality assurance/quality control (QA/QC) for stormwater monitoring. The policies and procedures described are intended to ensure that stormwater analytical data meet the requirements of the Permit.
This manual will assist in the development of erosion and pollution control measures during both design and construction of roadways. It outlines ADOT's procedures for complying with water quality regulations and permits, provides a variety of available Best Management Practices (BMPs), and guidance in the selection of those BMPs on ADOT construction project. The sediment control and water quality protection BMP detail drawings are also available for download on its separate Web page. They are periodically updated. Please refer to the list of these drawings frequently for future updates.
This updated manual guides all staff involved in implementing new development and redevelopment projects that disturb one or more acres of land in the ADOT MS4 (municipal separate storm sewer system). The manual includes planning considerations, design standards, and maintenance needs associated with stormwater treatment features that will continue to remove pollutants in runoff after construction is completed.
This manual will assist the user in establishing the proper erosion and pollution control measures to be used during the maintenance of roadways and operations of facilities. It outlines ADOT’s procedures for complying with water quality regulations, and guides in the selection of BMPs for ADOT maintenance activities and agency facilities operations.
Stormwater Enforcement Response Plan
This Stormwater Enforcement Response Plan (ERP) codifies enforcement procedures used by ADOT to enforce provisions of its Arizona Pollutant Discharge Elimination System (AZPDES) Statewide Stormwater Permit No. AZS000018-2008. This ERP describes the measures available to ADOT to exercise its authority. The ERP identifies enforcement procedures designed to encourage a timely response by the discharger
This manual provides an overview of Sections 404 and 401 of the Clean Water Act, as they apply to Arizona Department of Transportation activities.
