Water Protection Program fact sheet
Division of Environmental Quality Director: Ed Galbraith

The original 1948 Federal Water Pollution Control Act, now known as the Clean Water Act, has seen many changes. Among these changes are the 1972 amendments, which include the establishment of the National Pollution Discharge Elimination System (NPDES) in Section 402 of the act. "NPDES prohibits [discharges] of pollutants from any point source into the nation's waters except as allowed under an NPDES permit." In 1987, the act was amended to include the regulation of certain stormwater classes by NPDES permitting.

Through the NPDES permit program, the Missouri Department of Natural Resources has received authorization to regulate point sources that discharge pollutants into waters of the state. Point sources are generated from a variety of municipal and industrial operations, including treated wastewater, process water, cooling water, and stormwater runoff from drainage systems. The NPDES Stormwater Program has been in place since 1990 and regulates discharges from municipal separate storm sewer systems (MS4s), construction activities, industrial activities, and those designated by the U.S. Environmental Protection Agency due to water quality impacts.

Missouri Industrial Permits
The EPA delegated authority for the NPDES permitting program to the department in 1974. Although the federal government oversees and reviews the Missouri State Operating Permit program, the state issues and enforces these permits. Missouri’s stormwater regulations are located in 10 CSR-20.6.200. These laws require that permits be issued to certain industrial facilities for their discharges. A permit may be required for discharges of water contaminants to waters of the state or to a Municipal Separate Storm Sewer System (MS4).If the activity does not discharge any water contaminants to either, no permit is needed. If it does discharge water contaminants to one or both, or if the industrial activity is listed among the regulated categories and meets certain requirements as outlined in 10 CSR 20-6.200(2), a permit is required.

An industrial activity may be excluded from stormwater permitting if the activity does not expose materials to stormwater as stated in 10 CSR 20-6.200(1)16.Qualified permit holders as well as new applicants that qualify must submit a completed “No Exemption Certification” form (EPA form 3510-11) to the department. This form is available online at:

Who Needs a MO-G822 Permit
Stormwater and wastewater regulations use the Standard Industrial Classification (SIC) system to determine if an industry is regulated under the law. This classification system was devised by the U.S. Office of Management and Budget to cover all economic activities. Facilities having the SIC codes of 20XX (Food and Kindred Products) and 5812 (Eating Places) may need to apply to the department for Missouri State Operating Permit MO-G822 to discharge stormwater and wastewater. It is the responsibility of the owner or operator to apply for a MO-G822 permit. Questions regarding applicability of a MO-G822 permit should be directed to the appropriate regional office.

Permit Applications and Fees
Facilities applying for MO-G822 for the first time must submit application Form E (MO 780-0795), which can be found at, along with the appropriate fees. After issuance of the permit, fees will be assessed annually. To request a renewal of MO-G822, application Form E must be submitted at least 30 days prior to the expiration of MO-G822 along with appropriate fees. If the facility has any questions concerning fees, the facility needs to contact the appropriate regional office.

Permit Requirements
This document provides guidance for the meat processing industry. Meat processing facilities generally process 500 to 700 hogs per year and 300 to 500 cattle per year. An equivalent number of deer or other animals may be processed per year. Meat processing facilities must be designed as no-discharge facilities. The recommended treatment system for use under MO-G822 is a septic tank, followed by a storage lagoon, followed by a land application system.

The septic tank should be an 1,000 gallon tank that traps oil, grease, and solids. Following the septic tank, an earthen storage basin (lagoon) must be constructed in series with the septic tank. The lagoon must have a volume sufficient to store 60-120 days of wastewater flow, the amount of rainfall from the wettest 1-in-10 year precipitation event, and the 25-year 24-hour precipitation event. Following the lagoon, a land application field and a wastewater application system must be installed or made available. A wastewater application system usually consists of the following: pumps, sprinklers, center pivots, traveling guns, etc.

The area needed for land application is determined by the type of vegetation, slope of the land, geohydrologic characteristics, level of treatment, and other factors. Land application rates shall not exceed any of the following: Sludge shall not exceed 10 dry tons/acre/year; wastewater shall not exceed 0.2 inches/acre/hour, 0.5 inches/acre/day, 1.0 inches/acre/week, and 24 inches/acre/year. The wastewater or sludge must be used as fertilizer and soil amendment. The wastewater or sludge must be land applied in accordance with an approved Land Application Management Plan that conforms to the best management practices and other requirements contained in MO-G822.

Permit Exemptions
No-discharge land application facilities that generate less than 3,000 gallons per year and that are in compliance with Missouri Water Quality Standards (10 CSR 20-7.031) are exempted from MO-G822. This exemption only applies to the types of facilities described in MO-G822 and only to those facilities land applying wastewater. Additionally, one-time or short-term land application events during cleanup of spills or environmental emergencies are exempted from MO-G822 with prior approval from the department.

Important Permit Dates
MO-G822 is issued on a five-year cycle. Important dates of each permit are:

Transfer of Permit
A permit may be transferred to a new owner by submitting an Application for Transfer of Operating Permit (MO 780-1517), which can be found at, along with the appropriate fees.

Termination of Permit
General permits may be terminated when activities covered by the permit have ceased and no significant materials are stored in such a way as to come into contact with stormwater. When general permit termination is sought, the permittee must submit Form H, (MO 780-1409), which can be found at

Site-Specific Permit
If requested by the owner or operator, a facility may be covered by a site-specific permit. A site-specific permit takes into account the individual characteristics of the site. In addition, the department may determine that the quality of waters of the state can be better protected by requiring the owner or operator of a facility to apply for a site-specific permit. For questions or guidance regarding the need for a site-specific permit or to begin the application process for a site-specific permit, the facility should contact the appropriate regional office.
