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.
Erosion and Pollution Control Manual / BMP Detail Drawings
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
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
More information on erosion/sediment control, such as a listing of registered
landscape architects and professionals in erosion control, can be found
at the Roadside
Post-Construction Best Management Practices (BMP) Manual
This manual serves to guide the roadway designer, both
internal and external to ADOT, in the selection and design of
structural post-construction (permanent) BMPs. This manual formalizes
and compiles the post-construction BMPs that ADOT presently implements
along with the design of additional BMPs to allow ADOT to comply
with regulatory requirements and related permits.
Maintenance and Facilities Best Management Practices
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
Stormwater Monitoring Guidance Manual for Construction
This guidance will assist the user in preparing monitoring plans
required for construction activities located within ¼ mile
of a unique or impaired water, or any sensitive project as deemed
necessary by ADOT. This manual also includes detailed procedural
information and quality assurance and quality control requirements.
Stormwater Monitoring Guidance Manual for MS4 Activities
This MS4 stormwater monitoring plan has been revised to integrate
ADOT MS4 monitoring requirements.
Stormwater Monitoring Guidance Manual for Industrial
This manual will assist ADOT facilities subject to monitoring
and reporting requirements. The facilities include all ADOT-owned
or operated material source mining sites, the Grand Canyon National
Park Airport, and the Traffic Operations Sign Factory. (Note:
A fourth facility, the ADOT Print Shop, has a No-Exposure Exemption).
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.
