What is a Utah LTSWP?

A LTSWP is a Long Term Stormwater Pollution Prevention Plan, which is a document that describes how stormwater runoff from a regulated industrial facility will be managed and controlled to prevent or minimize potential impacts to water quality and quantity. A LTSWP is required for certain types of industrial facilities in Utah that discharge stormwater associated with industrial activity to waters of the state, or to a municipal separate storm sewer system (MS4). A LTSWP is also required for facilities that are subject to the Utah Pollutant Discharge Elimination System (UPDES) permit program.

A LTSWP is different from a LTSMP, which is a Long Term Stormwater Management Plan. A LTSMP is a document that describes how post-construction stormwater runoff from a regulated site will be managed and controlled to prevent or minimize potential impacts to water quality and quantity. A LTSMP is required for certain types of development projects in Utah that disturb one acre or more of land, or are part of a larger common plan of development that disturbs one acre or more of land. A LTSMP is also required for projects that are located within a sensitive area, such as a watershed, a wetland, or a floodplain.

A LTSWP is also different from a LTSWMP, which is a Long Term Stormwater Management Program. A LTSWMP is a comprehensive program that addresses stormwater runoff from existing and future sources within a designated area, such as a city, a county, or a region. A LTSWMP is required for certain entities that operate a MS4, such as municipalities, counties, universities, military bases, and transportation agencies. A LTSWMP is also required for entities that are designated by the Utah Division of Water Quality (DWQ) as needing a stormwater management program.

A LTSWP is a pre-construction and during-operation plan, while a LTSMP is a post-construction plan, and a LTSWMP is a programmatic plan. A LTSWP is designed to provide pollution prevention and source control of stormwater runoff, while a LTSMP is designed to provide long-term management and treatment of stormwater runoff, and a LTSWMP is designed to provide comprehensive and integrated management of stormwater runoff. A LTSWP is submitted to the DWQ for authorization, while a LTSMP is submitted to the local jurisdiction for approval, and a LTSWMP is submitted to the DWQ for approval.

A LTSWP typically includes the following elements:

A site map that shows the location and boundaries of the facility, the drainage areas, the stormwater conveyance systems, the stormwater control measures, and the receiving waters.

A description of the industrial activities, such as the processes, the materials, the products, the wastes, and the potential sources of pollutants.

A description of the stormwater control measures, such as the structural and non-structural practices, the best management practices (BMPs), the pollution prevention techniques, and the spill prevention and response procedures.

A description of the inspection and maintenance procedures, such as the frequency, the methods, the records, and the corrective actions.

A description of the monitoring and reporting requirements, such as the sampling, the analysis, the documentation, and the submission.

A LTSWP is a site-specific and customized plan that is tailored to the specific facility and its stormwater pollution prevention needs. A LTSWP is intended to reduce the discharge of pollutants from the facility and protect the water resources and the environment. A LTSWP is a proactive and preventive plan that requires the facility to implement and maintain the stormwater control measures and comply with the permit conditions.

If you are operating or planning to operate an industrial facility that requires a LTSWP in Utah, you may want to consult with a professional stormwater management company that can help you with the preparation, implementation, and maintenance of your LTSWP.

These companies have the expertise, experience, and equipment to provide you with the best and most cost-effective stormwater solutions for your facility. They can also help you with your other stormwater compliance requirements, such as the inspections, the BMP installation and maintenance, the sampling and analysis, and the reporting.
