Regulatory Control Branch:  Pretreatment Program

back to Division of Environmental Quality

Rules Relating To Grease Interceptor Program Compliance

Adopted 3/05/02 for Adobe Acrobat Reader (.pdf) 215 KB

Pretreatment Program

The Pretreatment Program monitors wastewaters to prevent the discharge of any substance that might harm the environment or cause damage to the sewer system. Any commercial industrial discharge into the sewer system must be approved by Regulatory Control (RC) Branch.

1.  The Regulatory Control Branch reviews the operations of a business to determine if the water they wish to discharge to the sewer poses a threat to the operations and health of the city sewer system.  If an operation is likely to discharge harmful materials like large amounts of fats, oils and grease into the city sewer system, they must install a pretreatment system to prevent harm to the city sewer.

A business in this position needs to undergo a detailed plan review as described in the rules documents on this page.
