Purpose and Background

Developing a forward-looking sampling program for a local wastewater collection system can lead to Pretreatment Local Limits that both better protect the publicly owned treatment works (POTW) and allow for less stringent pretreatment limits. This can ease compliance requirements and allow for less sensitive and lower cost sample analysis that will save money for both the Utility and industrial dischargers.

POTWs are frequently required to develop Local Limits for their Pretreatment programs. These programs are developed using a standardized process that relies on important background data, such as the removal efficiency and background levels for pollutants of concern. This data isn’t usually available locally, so reference data is usually used. However, much of this reference data dates back 30 to 40 years. Since that time, treatment technologies and detection methods have greatly improved.

This workshop will demonstrate how to identify, collect and leverage the needed site-specific information to develop Pretreatment Local Limits that are both accommodating to local industry and save money for both the user and the utility.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Explain the RPA process as it applies to the POTWs permit review & discharge requirements
• Develop draft local limits to support local business development
• Setup a site specific sampling program that reduces or minimizes risk and ongoing compliance sampling costs for Industrial Dischargers and POTW
• Explain how industrial dischargers and POTWs can identify appropriate cost saving methods for pretreatment program requirements
• Explain how POTWs can develop less restrictive local limits
• Explain how POTWs can setup proactive sampling program to identify & mitigate costs and compliance risks
• Explain how POTWs and industrial dischargers can be prepare for regulatory compliance with forward looking sampling programs

Assessment of Learning Outcomes

Achievement of the learning outcomes by attendees will be assessed through in-class discussion, homework, and a short post-assessment (true-false, multiple choice and fill in the blank questions) will also be administered.
