2. ADOT Statewide Storm Water Permit Application
This Permit Application is available for download on its own separate Web page. It reflects the current Arizona storm water regulatory structure and covers various activities and locations for which there was no existing, appropriate permit application. ADOT submitted the application in March 2005 and received a completeness letter from ADEQ in July 2005.

3. Construction Storm Water Pollution Prevention Plan (SWPPP) Template
Note: Please download the instructions first and read them before downloading the Construction SWPPP Template. This template is to help ensure that the SWPPP contains all required components. ADOT has recently compiled comments and evaluated changes to the second version of the template. Changes made to the second version include clarifying some sections, revising tables and checklists for ease of use, modifying reporting forms, and making the template consistent with recent changes to ADOT storm water guidance. The third version of the Construction SWPPP Template is available for download below.
You are welcome to send additional comments on this revised template through the Contact page at the Office of Environmental Services site.

9. Erosion and Pollution Control Manual / BMP Detail Drawings
This manual will assist in the development of erosion and pollution control 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 downloaded material for this manual is available on its own separate Web page.
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.
Appendix A.6 - Methodology for Determining Final Stabilization within the Erosion and Pollution Control Manual has been recently revised and is available at the third link below.
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 Development Section.
