Industrial Pretreatment regulates all industrial users served by MSD. There are 1500 regulated industries in St. Louis City and St. LouisCounty, and 220 are regulated and permitted in the pretreatment program. All industries must comply with the MSD's Ordinance No. 12559.
MSD uses a Pretreatment Enforcement Response Plan to mitigate violation of program requirements and standards. Informal actions, such as telephone notification, compliance meetings, or notices of violations, are used.
When more formal and progressive enforcement is necessary, MSD's ordinance provides formal enforcement tools such as administrative orders, emergency actions, legal actions, revocation of permit and cost recovery.
When violations appear to be of a criminal nature, we request support from higher authority. An Environmental Crimes Task Force serves the United States Attorney in the Eastern District of Missouri where MSD is located.
Federal regulations require MSD to publish, on an annual basis, all industrial users found to be in significant noncompliance during the previous year. MSD uses its fiscal year (July 1 through June 30) as the basis for its publication list. The criteria used to determine if an industrial user is in significant noncompliance can be found in Article II, Ordinance 12559.
Federal Regulations require MSD to identify the character and volume of pollutants contributed by industrial users. Article VIII, Section One of Sewer Use Ordinance No. 12559 provides for a questionnaire to be completed by industrial users to obtain this information. The questionnaire and instructions are in PDF format and require Adobe Reader.
The questionnaire can be completed in two ways:
- Interactively--Answer the questions on screen, then print the finished document.
- On paper--Print the blank document, then answer the questions on the hard copy.
