Introduction to 40 CFR 122.44
The National Pollutant Discharge Elimination System (NPDES) permit program is a federal program that regulates the discharge of pollutants into the waters of the United States. 40 CFR 122.44 is a specific regulation that outlines the requirements for establishing NPDES permit conditions for industrial and municipal facilities.
The regulation sets forth the procedures for determining the effluent limitations and other conditions that must be included in an NPDES permit. This includes the types of pollutants that must be controlled, the levels of treatment required, and the monitoring and reporting requirements.
Determining Effluent Limitations
40 CFR 122.44 requires that NPDES permits include effluent limitations that are based on the best available technology (BAT) or the best conventional technology (BCT) for the specific industry or facility. The regulation also allows for the use of water quality standards to establish effluent limitations.
The effluent limitations must be based on a thorough analysis of the facility's operations, including the types and quantities of pollutants discharged, the treatment technologies used, and the receiving water quality. The limitations must also take into account any applicable water quality standards and other regulatory requirements.
Permit Conditions and Requirements
In addition to effluent limitations, 40 CFR 122.44 requires that NPDES permits include other conditions and requirements, such as monitoring and reporting requirements, record-keeping requirements, and inspection and enforcement provisions.
The permit must also include requirements for the facility to implement best management practices (BMPs) to minimize the discharge of pollutants and to prevent spills and other accidents. The permit must also include provisions for the facility to report any non-compliance with the permit conditions.
Public Participation and Comment
40 CFR 122.44 requires that the public be given the opportunity to comment on draft NPDES permits before they are issued. The regulation requires that the permitting authority provide notice of the draft permit and allow for a public comment period.
The public comment period provides an opportunity for the public to review the draft permit and provide comments on the proposed effluent limitations and other permit conditions. The permitting authority must consider all comments received during the public comment period before issuing the final permit.
Enforcement and Compliance
40 CFR 122.44 requires that NPDES permits include provisions for enforcement and compliance, including provisions for inspections, monitoring, and reporting. The regulation also requires that the permitting authority take enforcement action against facilities that are not in compliance with the permit conditions.
The regulation also provides for the use of civil and criminal penalties to enforce compliance with the permit conditions. Facilities that are found to be in non-compliance with the permit conditions may be subject to fines, penalties, and other enforcement actions.
Frequently Asked Questions

The purpose of 40 CFR 122.44 is to establish the requirements for determining NPDES permit conditions for industrial and municipal facilities.
What are effluent limitations and how are they determined?
Effluent limitations are the maximum amounts of pollutants that can be discharged from a facility. They are determined based on the best available technology or the best conventional technology for the specific industry or facility.
What are the requirements for public participation and comment on NPDES permits?
The public must be given the opportunity to comment on draft NPDES permits before they are issued. The permitting authority must provide notice of the draft permit and allow for a public comment period.
What are the consequences of non-compliance with NPDES permit conditions?
Facilities that are found to be in non-compliance with NPDES permit conditions may be subject to fines, penalties, and other enforcement actions, including civil and criminal penalties.
How often must NPDES permits be renewed?
NPDES permits must be renewed every 5 years. The permitting authority must review and update the permit conditions as necessary to ensure that the facility is in compliance with the regulations.
Can NPDES permits be modified or revoked?
Yes, NPDES permits can be modified or revoked if the facility is found to be in non-compliance with the permit conditions or if there are changes in the facility's operations or the receiving water quality.
