Water Pollution Control Permit Manual

The Water Pollution Control Permits Manual presents guidance related to water pollution control

  • construction permits,
  • operating permits, also known as NPDES Permits,
  • general permits,
  • no-discharge permits,
  • Stormwater and land disturbance permits, and the
  • legal bases, policies and procedures related to them.

The Water Pollution Control Permits Manual is a tool for department staff writing permits under the Missouri Clean Water Law.  It is not intended to answer all questions a permit writer may have, but is a starting point for basic information and a tool to find other resources.  It is intended to help all DNR offices involved in water pollution control permitting follow the same basic processes and guidelines when drafting permits.  Consistency is the goal.

To help our permittees, consultants and other customers better understand the permit process, the department is making the manual widely available. Since it is too large to distribute as hard copy, especially since we plan to update it regularly, the department is making it available as a download through a link on this page. We hope that permittees and consultants will use the manual to better understand the permit process and aid their communications with our staff permit writers.  We encourage users to help us improve the manual by letting us know of errors and outdated procedures.

You can identify incomplete topics and learn how to use the manual by reading Chapter 0 - Using the Water Pollution Control Permit Manual.  We will maintain a compendium of changes so that with each update, users can readily identify additions and changes.

Throughout the manual, there are information links to federal and state statutes, rules and technical guidance documents that support permit procedures. The numbering and lettering system of the table of contents is not always consecutive. The gaps indicate inactive, reserved topics or appendices. Future revisions of the manual will result in changes to both the contents and the organizational format and the gaps will disappear.
