EPA Compliance Advisories

  • Clean Water Agencies Increasing Attention to Significant Non-Compliance Dischargers

    This NCI is intended to ensure that all NPDES permittees—not just industrial contributors—are complying with their permits. NPDES permittees, regardless of facility size or type, will see an increase by EPA and its state and tribal partners in identifying and addressing SNC violations using enforcement and other compliance tools. This NCI aims to cut significant non-compliance in half and to ensure that the most serious SNC violations are timely and appropriately addressed. Increased compliance will improve surface water quality and reduce potential impacts on drinking water.

  • FF-NPDES SNC Advisory Summary

    This advisory is intended to notify federal facilities with NPDES permits about an EPA-State enforcement and compliance initiative focused on improving permit compliance and to help permittees with compliance problems achieve or maintain compliance.

  • Final SNC Compliance Advisory Tips Small Mechanical WWTP Summary

    This advisory is directed to owners and operators of small publicly owned wastewater treatment works (POTWs) and small private wastewater treatment plants, both commonly referred to as wastewater treatment plants (WWTPs). It is intended to provide small WWTPs with information that will help them comply with their National Pollutant Discharge Elimination System (NPDES) permit effluent limits.

  • Compliance Tips for Small Wastewater Treatment Lagoons with Clean Water Act Discharge Permits

    This advisory is written to assist owners and operators of small publicly and privately owned lagoon wastewater treatment plants (WWTPs) to comply with the law. This advisory provides extensive information on the causes of, and potential solutions to, lagoon WWTP noncompliance. While this advisory focuses on operational issues affecting small lagoon WWTPs, another frequently identified noncompliance concern at small lagoon WWTPs is the failure of owners and operators to submit required discharge monitoring reports (DMRs) or the submittal of incomplete or inaccurate DMRs.

EPA Technical Assistance Webinar Series


EPA's Office of Compliance invites you to a free monthly webinar series focused on improving CWA-NPDES permit compliance at Small Wastewater Treatment Systems. This webinar series supports the joint EPA and Authorized State Significant Noncompliance (SNC) Rate Reduction National Compliance Initiative (NCI), which is aimed at improving surface water quality and reducing potential impacts on drinking water by assuring that all Clean Water Act (CWA) – National Pollutant Discharge Elimination System (NDPES) permittees are complying with their wastewater discharge permits. The most common dischargers in significant noncompliance are wastewater treatment systems discharging less than one million gallons per day.

All registered attendees receive a follow-up email from GoToWebinar 24 hours after the conclusion of the webinar including a link to download a certificate of attendance. Attendees may check with their relevant state certification authority for eligibility of continuing education credits. Please note that Certificates of Completion are NOT issued for viewing past recorded webinars.

Upcoming and Recent Webinars

Providing Process Control Technical Assistance to Small Mechanical WWTPs

The first part of this webinar will discuss the Ammonia Removal Best Practices Excel-Based Tool. This tool provides a systematic approach for wastewater operators to guide their efforts when optimizing their system for Ammonia removal or attempting to return to compliance for Effluent Ammonia. The second part of the webinar will review a video series where Ohio EPA engineer, Jon VanDommelen, demonstrates the use of process control tools to help small wastewater treatment systems either return to compliance or maintain compliance. Jon walks through each treatment unit with the audience, identifies tools and equipment that can help operators diagnose operational problems, and then demonstrates how to use the tools in a troubleshooting exercise.

Making the Right Choices for Your Utility: Using Augmented Alternatives Analysis Planning for Water Infrastructure

All across America, drinking water, wastewater and stormwater utilities are charged with safeguarding public health, protecting the environment, and sustaining critical water infrastructure investments for their communities. EPA estimates that roughly $655 billion will need to be invested in water infrastructure over the next 20 years. To meet these ambitious goals at the local and national level, meaningful community involvement and enhanced decision-making tools are critical to equitable multi-benefit investments. Traditional project alternative analysis often falls short in proactively engaging the community to understand their priorities; addressing and quantifying and social benefits and costs associated with these long-term infrastructure investments; and, selecting the most cost-effective project alternative in a complex decision-making context when there are multiple drivers. EPA’s water infrastructure capital project decision-making tool, referred to as Augmented Alternatives Analysis (AAA), can help water utilities embed principles of sustainability and community driven planning into their investment decisions to address the challenges and expectations of modern-day project decision-making.

Join us for an overview of the AAA planning process, and receive first-hand experience from a former utility leader who participated in the process.
