What is a Utah Stormwater N.O.T.?

What is Utah Stormwater Management?

In Utah, the management of stormwater is a critical aspect of environmental protection. Ensuring that stormwater is properly managed and free from pollutants is essential to safeguarding our natural water resources including our rivers and lakes.


What is a Utah Stormwater N.O.T.?

A Utah Stormwater Notice of Termination, commonly referred to as a Stormwater N.O.T., is a formal document submitted to the Utah Division of Water Quality (DWQ) to notify them that a site or facility is ending its obligations under the Utah Pollutant Discharge Elimination System (UPDES) permit for stormwater discharges.


UPDES permits are required for facilities that discharge stormwater associated with construction activities, industrial processes, or municipal separate storm sewer systems (MS4s).

The Stormwater N.O.T. serves as evidence that the site or facility has successfully implemented stormwater management practices and measures to prevent pollution, and it is no longer discharging stormwater associated with its permit.

Significance of the Stormwater NOT

The Stormwater N.O.T. holds significant importance for both the regulated entities and environmental protection agencies in Utah. Here's why it matters:

  1. Compliance Verification: The N.O.T. is a formal confirmation that the site or facility has met all the necessary requirements and regulations set forth in the UPDES permit. This demonstrates compliance with stormwater management standards.

  2. Environmental Protection: By ensuring that the site or facility has effectively managed stormwater and minimized pollutant discharges, the N.O.T. plays a vital role in protecting local water bodies and ecosystems.

  3. Legal Obligations: Submitting a Stormwater N.O.T. is not just a formality; it is a legal obligation. Failure to submit a N.O.T. when required can result in non-compliance penalties.

Steps Involved in the Stormwater N.O.T. Process

Submitting a Stormwater N.O.T. involves a series of steps to ensure proper termination of UPDES permit obligations. Here's an overview of the process:

  1. Compliance Assessment: Before submitting a N.O.T., the site or facility must thoroughly assess its stormwater management practices to ensure that all permit requirements have been met.

  2. Documentation: Gather all necessary documentation, including records of stormwater monitoring, inspections, maintenance activities, and any other relevant data that demonstrate compliance.

  3. Complete the N.O.T. Form: Obtain the official Utah Stormwater N.O.T. form from the Utah DWQ website and complete it accurately. Include all required information, such as facility details, permit information, and a summary of stormwater management practices.

  4. Sign and Certify: The N.O.T. form must be signed and certified by an authorized representative of the site or facility.

  5. Submit to Utah DWQ: Send the completed N.O.T. form to the Utah DWQ in accordance with their submission instructions, which may include mailing or electronic submission.

  6. Await Confirmation: After submission, await confirmation from the Utah DWQ that the N.O.T. has been received and accepted. The agency may conduct a review of the submitted information.

The Utah Stormwater N.O.T. is a crucial document in the process of ending stormwater permit obligations.


By following the proper steps and ensuring compliance with stormwater management regulations, regulated entities contribute to environmental protection and demonstrate their commitment to responsible stormwater management.


Understanding the significance of the Stormwater N.O.T. is essential for those who have implemented effective stormwater management practices and are ready to terminate their UPDES permit obligations in Utah.
