Which BMP is typically part of a FOG program?

• A. Grease trap inspections and ongoing education program for businesses and residents
• B. Installing chemical inhibitors in pipes
• C. Increasing chlorination to oxidize fats
• D. Bypassing grease interceptors during high flow

Answer: (A)

Understanding how fats, oils, and grease (FOG) are managed in the sewer system is key. A typical BMP for FOG programs focuses on preventing grease from entering the sanitary sewer in the first place, through regular maintenance and education. Grease trap inspections ensure traps are working properly and grease is removed before it can accumulate and cause blockages. Ongoing education for businesses and residents helps everyone know how to dispose of grease correctly, what to keep out of drains, and how often traps need service. This combination reduces sewer blockages and costly grease spills.

Why the other ideas aren’t effective BMPs: using chemical inhibitors in pipes doesn’t address routine grease buildup and can create safety or environmental concerns; increasing chlorination to oxidize fats isn’t a practical or targeted method for FOG control and can cause other problems like corrosion or disinfection byproducts; bypassing grease interceptors during high flow defeats the purpose of interceptors and would allow grease to enter the sewer, worsening blockages and overflows.
