Stormwater BMP Installation, Maintenance, and Inspection Services in Tennessee
Tennessee property owners, contractors, and municipalities managing stormwater compliance operate under a framework administered by the Department of Environment and Conservation (TDEC). Construction sites disturbing one or more acres require a Stormwater Pollution Prevention Plan (SWPPP) and coverage under the NPDES Construction General Permit. TDEC updated its Erosion Prevention and Sediment Control (EPSC) Handbook effective January 9, 2026, and the current NPDES Construction General Permit is set to expire September 30, 2026, with a new permit currently in drafting. Post-construction stormwater requirements in Tennessee are implemented through local MS4 programs, which means compliance obligations vary by municipality. Exact Stormwater Management provides stormwater BMP installation, maintenance, and inspection services across Tennessee, supporting property owners, contractors, and municipalities navigating both state and local requirements during an active regulatory transition period.
Regulatory Context
Tennessee's stormwater program is administered by TDEC's Division of Water Resources. The NPDES Construction General Permit currently in effect is set to expire September 30, 2026, and TDEC is currently drafting its replacement. Construction sites should anticipate possible changes to permit conditions, inspection frequency requirements, and SWPPP standards as the new permit is finalized. TDEC's EPSC Handbook, updated effective January 9, 2026, establishes the current technical standards for erosion prevention and sediment control on Tennessee construction sites. Tennessee uses both EPSC and BMP terminology, which is worth noting when reviewing local program requirements. Post-construction stormwater requirements are implemented through local MS4 programs and vary significantly by jurisdiction, making familiarity with local ordinances essential for property owners managing stormwater facilities in Tennessee cities and counties. Exact provides installation, maintenance, and inspection services that address both TDEC construction permit requirements and local MS4 post-construction obligations across Tennessee.

Frequently Asked Questions: Tennessee Stormwater BMP Services
What stormwater permits are required in Tennessee?
Construction sites in Tennessee disturbing one or more acres require coverage under the TDEC NPDES Construction General Permit and a Stormwater Pollution Prevention Plan (SWPPP). The current permit is set to expire September 30, 2026, with a replacement currently in drafting by TDEC's Division of Water Resources. Post-construction stormwater requirements are implemented through local MS4 programs, which vary by municipality and county. Property owners should verify their local program's specific inspection and maintenance requirements.
Who provides stormwater BMP maintenance in Tennessee?
Stormwater BMP maintenance in Tennessee is typically contracted to qualified stormwater contractors familiar with local MS4 program requirements. Because post-construction requirements vary by jurisdiction in Tennessee, selecting a provider with statewide experience across multiple local programs is important. Exact Stormwater Management provides BMP maintenance services across Tennessee, with crews experienced in TDEC construction requirements and local MS4 post-construction standards. Call (804) 302-5151 to discuss a maintenance program.
What is the TDEC EPSC Handbook?
Tennessee's Erosion Prevention and Sediment Control (EPSC) Handbook is the technical reference document governing erosion and sediment control practices on Tennessee construction sites. TDEC updated the Handbook effective January 9, 2026, establishing current standards for practice selection, installation, and maintenance. Contractors working under active NPDES Construction General Permit coverage in Tennessee are expected to implement practices consistent with the current EPSC Handbook. The Handbook uses both EPSC and BMP terminology throughout.
What stormwater installation and maintenance services are available in Tennessee?
Exact Stormwater Management provides stormwater BMP installation, inspection, annual maintenance programs, erosion control consistent with TDEC's updated EPSC Handbook, geomembrane liner installation, permeable pavement, pond management through our Aquatics Group, and green infrastructure throughout Tennessee. Our services address both TDEC construction permit requirements and local MS4 post-construction obligations. Contact (804) 302-5151 to discuss your Tennessee stormwater compliance needs.
How are post-construction stormwater requirements different across Tennessee?
Post-construction stormwater requirements in Tennessee are implemented primarily through local MS4 programs rather than a single uniform state standard. This means inspection frequency, maintenance documentation requirements, and compliance expectations can differ significantly between Nashville, Knoxville, Memphis, Chattanooga, and smaller jurisdictions. Property owners managing stormwater BMPs in Tennessee need to confirm both TDEC state permit requirements and the specific requirements of their local MS4 program to ensure complete compliance.

INSTALLATION: Bioretention Facility, Biofilter, Dry Swale
Bioretention systems, biofilters, rain gardens, dry swales, compost amended grass swales, and many other variations of a semi-natural stormwater filter all serve to clean stormwater before it enters our streams. We specialize in proper installation of these systems - the right materials in the right arrangement at the right time - to make sure the system works as designed.

INSTALLATION: Green Infrastructure
Green Infrastructure refers to a strategic approach that utilizes natural processes and systems to manage stormwater, enhance urban environments, and improve overall ecosystem health. This method emphasizes the preservation and restoration of natural landscapes while integrating them into urban design. Interventions such as rain gardens, permeable pavement, and bioswales work collectively to absorb, infiltrate, and filter stormwater runoff, reducing flooding risks and pollutant discharge into waterways.

INSTALLATION: Permeable Pavement
Permeable pavements are alternative paving surfaces that allow stormwater runoff to filter through voids in the pavement surface into an underlying stone reservoir, where it is temporarily stored and/or infiltrated. We install many types of permeable pavements from grass pavers to concrete brick-type pavers.
