What is a LTSWP in Utah?

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.
