Water Quality Permits - NPDES Permit Template

Overview

In early 2012, DEQ undertook the development of a template for NPDES individual permits. The purpose of the template is to improve permit consistency, as well as transparency regarding the permit development process. DEQ permit writers are expected to use the permit template for all individual NPDES permits issued after January 1st, 2013. The template is available on the DEQ website so that permit holders and the public can have a better understanding of the permit development process.

Features of the permit template:

• Highlighted instructions. These call attention to language that may need to be tailored for particular permits.


• Endnotes. These are designed to provide the legal basis and additional background on specific permit language.


• Links to various documents developed to inform the permit development process.

The current version of the template applies primarily to NPDES domestic permits. DEQ anticipates revising the template on a regular basis. Over time, DEQ expects to develop additional versions tailored to industrial and WPCF permits.
