Significant Non-Compliance (SNC) National Compliance Initiative (NCI) Advisory:  EPA has released the general SNC NCI Compliance Advisory. The goal of this NCI is to ensure “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 compliance tools, including enforcement. The SNC NCI aims to cut significant non-compliance by 50% and to also ensure that the most serious SNC violations are timely and appropriately addressed. States, interstates, territories, industry groups, municipal groups and other entities that communicate regularly with NPDES permittees are encouraged to circulate this Compliance Advisory.
