Key activities in the Water Pollution Control Branch include the issuance of permits to build, erect, alter, replace, operate, use or maintain existing point sources of water pollution. The majority of our permits are for the discharge of treated wastewater from domestic and industrial facilities. We also issue permits for land application of wastes from domestic, industrial and agricultural facilities. Our permits usually specify requirements for regular sampling of wastewater at the discharge points. In the case of land application, the permit specifies the methods by which wastes are handled and disposed. Permits also specify water quality standards for any discharges.

Most of these permits are written to be site-specific to reflect the unique nature of the waste water or the receiving stream. These permits usually have a five year cycle. As a permit expires, it is re-drafted, modified if needed, then placed on public notice for 30 days. When on public notice, a draft permit is open for comments. When the 30-day notice period expires, comments are reviewed and the permit is issued with needed changes, modified and re-noticed to resolve any concerns.

General Permits (as opposed to site-specific permits) are issued to multiple locations where activities are similar enough to be covered by a single set of requirements. These permits are identified by the prefixes MO-R or MO-G, which appear in the permit numbers. The conditions in General Permits are placed on public notice prior to being issued to applicants. After being finalized, a General Permit cannot be modified. All facilities receiving a General Permit must adhere to the conditions contained in the General Permit until it expires or until the facility obtains a site-specific permit. General Permits for airports, chemical manufacturing, fabricated structured metal, foundries, limestone and rock quarries, lubricant manufacturing, petroleum storage greater than 50,000 gallons and wood treaters are required to be placed on public notice prior to issuance to a new facility.

We are posting draft and final, site-specific permits on the Internet as a means to increase the availability of this information. We are not yet prepared to receive electronic comments. Therefore, we request that comments on the posted draft permits be sent through regular mail as described in the public notice until we are able to process the comments electronically.  Permits will be placed on this site for public access as they are listed for public notice and final issuance.

Permits are listed by the date that a public notice was first published.

Permit Synchronization
The Department of Natural Resources is currently undergoing a synchronization process for operating permits. Permits are normally issued on a five-year term, but to achieve synchronization many permits will need to be issued for less than the full five years allowed by regulation. The intent is that all permits within a watershed will move through the Watershed Based Management cycle together will all expire in the same fiscal year.

To detemine the expiration of a facility please see the Permit Synchronization List
Facilities are in order by permit number. If you do not know your permit number, cannot find your facility, or have any other questions, please call the Operating Permits Section at 573-522-4502 for assistance.
