NATIONAL COMPLIANCE INITIATIVE (NCI)

EPA’s NCI: Reducing Significant Non-Compliance with National Pollutant Discharge Elimination System (NPDES) Permits strives to improve surface water quality and reduce potential impacts on drinking water by assuring that all Clean Water Act National Pollutant Discharge Elimination System (NPDES) permittees are complying with their permits.

Over 29 percent of the approximately 46,000 major and minor NPDES-permitted facilities were in significant noncompliance (SNC) with their permits in FY 2018! EPA’s NCI aims to reduce this number by half by the end of FY 2022.

Compliance Advisory. EPA is increasing attention on all non-compliant individually permitted Clean Water Act National Pollutant Discharge Elimination System (NPDES) permit holders. EPA advises that permit holders review their discharge monitoring reports (DMRs), check their compliance history using EPA's Enforcement and Compliance History Online (ECHO) tool and take immediate action to correct violations.

PROPOSED 2022 CLEAN WATER ACT FINANCIAL CAPABILITY ASSESSMENT GUIDANCE

EPA's new proposed guidance outlines strategies for communities to support affordable utility rates while planning future CWA-required investments in water infrastructure. This guidance will describe the financial information and formulas EPA intends to use to assess communities' financial resources to meet CWA requirements and create timelines to implement control measures.

The finalized 2022 FCA will replace the 1997 Guidance for Financial Capability Assessment and Schedule Development.

Local governments are responsible for designing, planning, constructing, financing, operating and maintaining wastewater treatment facilities, and their conveyance systems, known as publicly owned treatment works (POTWs), in compliance with Clean Water Act (CWA) regulations. POTWs collect wastewater from homes, commercial buildings and industrial facilities and transport it via a series of pipes, known as a collection system, to the treatment plant. Here, the POTW removes harmful organisms and other contaminants from the sewage, so it can be discharged safely into the receiving waters.

Generally, POTWs are designed to treat domestic sewage only, but they also receive wastewater from industrial users. EPA’s General Pretreatment Regulations establish responsibilities of federal, state and local government, industry and the public to implement Pretreatment Standards. The Standards aim to control pollutants originating with industrial users which may pass through or interfere with POTW treatment processes or which may contaminate sewage sludge.

Collection systems that were designed to carry stormwater as well as sewage (combined systems) can also raise compliance issues when, during and after wet weather events, they exceed the conveyance and treatment capacity of the POTW and result in untreated discharges (combined sewer overflows, or ’CSOs’).

Other wastewater collection and treatment activities that have compliance obligations include laboratory operations, biosolids management and disposal, chemical storage/hazardous materials management and vehicle/equipment management.

EPA administers the CWA programs with which local government must comply. Under the CWA, a permit is needed to discharge a pollutant from a point source, such as a POTW, into the waters of the United States. CWA implementation is primarily carried out by states and several Tribes under delegated authority. EPA retains direct regulatory authority in a few states, all U.S. territories, and much of Indian Country. Implementation includes issuing NPDES permits to owners/operators of POTWs.

Permittees must comply with their designated discharge limitations and submit ’discharge monitoring reports’ (DMRs) showing their compliance with permit conditions. EPA establishes primary and secondary treatment standards, which are minimum, technology-based requirements for municipal wastewater treatment plants.

Permittees must also prevent unauthorized discharges, such as sanitary sewer overflows (SSOs) and CSOs. This includes implementation of control strategies and, in the case of CSOs, long-term control plans.

Most collection systems constructed since the 1950s use dedicated sanitary sewers. However, these sometimes suffer from infiltration and inflow (I/I) of stormwater or groundwater, often during wet weather events. Large volumes of I/I can cause sanitary sewer overflows and operational problems at the wastewater treatment facility serving the collection system. Sewage overflows can be caused by other problems such as blockages, equipment failures, broken pipes or vandalism.

SSOs that reach waters of the U.S. are considered point source discharges. This means SSOs are prohibited unless authorized by a NPDES permit. Under the Supreme Court's recent decision in County of Maui v. Hawaii Wildlife Fund ('Maui decision'), SSOs that are discharged to groundwater and conveyed to waters of the U.S. may also constitute violations (EPA's Office of Water in September 2021 rescinded its earlier guidance document). Moreover, SSOs, including those that do not reach waters of the U.S., may indicate that sewer systems are being improperly operated or maintained and may violate NPDES permit conditions.

SSOs can be prevented or controlled by following facility and operational best practices, including:

CSOs convey untreated or partially treated human and industrial waste, toxic materials and stormwater. EPA has prescribed nine minimum controls for operators of CSSs to implement. Permittees must prepare and implement a long-term control plan to eliminate the CSO and meet water quality standards. The nine minimum controls are:

CWA regulations apply to management of biosolids, a byproduct of wastewater treatment. Section 405(d) of the CWA requires EPA to establish numeric limits and management practices that protect public health and the environment from the reasonably anticipated adverse effects of chemical and microbial pollutants during the use or disposal of sewage sludge. EPA also reviews biosolids regulations every two years to identify any additional pollutants that may occur and establishes regulations for those pollutants that prove harmful to human health or the environment.

EPA oversees implementation of these programs and may take direct enforcement action even in states and Tribes that have received approval to operate these permit programs. EPA and the U.S. Department of Justice have brought enforcement actions against cities and municipal POTWs, entering into consent decrees (agreements filed with federal courts) with the municipalities to ensure correction of violations and investment of funds.

EPA’s Office of Wastewater Management (OWM) oversees programs protecting the nation's waters and watersheds. Its mission focuses on control of water and wastewater that is collected in discrete conveyances (also called point sources), including pipes, ditches and sanitary or storm sewers. OWM is home to the Clean Water State Revolving Fund, focused on providing low-cost financing for local wastewater treatment systems, nonpoint source projects and estuary protection through support of state revolving funds. OWM also administers the Water Infrastructure Finance and Innovation Act (WIFIA) program established in 2014, a federal loan program for water and wastewater infrastructure projects.

OWM’s website offers a substantial set of resources, rulemakings and guidance documents helpful for local governments. ’
