Stormwater BMP Installation, Maintenance, and Inspection Services in Texas
Texas operates its own stormwater permitting system through the Texas Commission on Environmental Quality (TCEQ) under the Texas Pollutant Discharge Elimination System (TPDES), independent of the federal NPDES program administered by the EPA in other states. Construction sites disturbing one or more acres require coverage under the TPDES Construction General Permit TXR150000, renewed March 5, 2023, and a Stormwater Pollution Prevention Plan (SWP3). Post-construction stormwater requirements in Texas are implemented through local MS4 programs, with the NCTCOG iSWM Criteria Manual widely adopted across the Dallas-Fort Worth region. The Edwards Aquifer recharge zone in Central Texas carries additional compliance requirements for development and stormwater management activities. Exact Stormwater Management provides stormwater BMP installation, maintenance, and inspection services across Texas.
Regulatory Context
Texas operates TPDES rather than NPDES, making TCEQ the sole permitting authority for construction and industrial stormwater in the state. The current TPDES Construction General Permit TXR150000 was renewed March 5, 2023, establishing current inspection, SWP3, and reporting requirements for construction sites. Post-construction stormwater requirements in Texas are primarily implemented through local MS4 programs, and compliance obligations vary significantly across the state's diverse geography and regulatory landscape. The NCTCOG iSWM Criteria Manual is widely adopted in the Dallas-Fort Worth region, making iSWM compliance the standard for post-construction BMP design in North Texas municipalities. In Central Texas, development over the Edwards Aquifer recharge zone requires additional safeguards to protect the aquifer from contamination. Some Texas jurisdictions, including parts of Bexar County, require quarterly maintenance reports and annual permit renewals with a certified maintenance provider, establishing a more rigorous compliance framework than most Texas localities. Exact provides installation, maintenance, and inspection services aligned with TCEQ requirements and local MS4 program standards across Texas.

Frequently Asked Questions: Texas Stormwater BMP Services
What is TPDES in Texas stormwater?
TPDES stands for Texas Pollutant Discharge Elimination System, Texas's own permitting program administered by TCEQ that operates independently from the federal NPDES program used in most other states. TCEQ issues stormwater permits directly under TPDES, including the TPDES Construction General Permit TXR150000, which applies to construction sites disturbing one or more acres. Because Texas operates TPDES independently, construction and industrial stormwater permits in Texas are governed by TCEQ requirements rather than EPA NPDES standards.
How often do stormwater BMPs need inspection in Texas?
Inspection frequency for post-construction stormwater BMPs in Texas is established by local MS4 programs, which vary by municipality and county. Some Texas jurisdictions, including parts of Bexar County, require quarterly maintenance reports and annual permit renewals with a certified maintenance provider, while other Texas localities require less frequent inspections. In the Dallas-Fort Worth region, iSWM criteria guide post-construction maintenance standards. Property owners should confirm inspection frequency requirements with their applicable local MS4 program.
What are the stormwater requirements for Edwards Aquifer development in Texas?
Development over the Edwards Aquifer recharge zone in Central Texas carries additional stormwater management requirements beyond standard TPDES and local MS4 obligations. The Edwards Aquifer is a karst limestone system that is highly sensitive to surface contamination, and stormwater discharges in the recharge zone can directly affect groundwater quality. Projects in the recharge zone typically require enhanced stormwater treatment, more stringent BMP design standards, and additional regulatory coordination with applicable local and state authorities.
What is iSWM and how does it apply in Texas?
iSWM stands for integrated Stormwater Management, a technical criteria framework developed by the North Central Texas Council of Governments (NCTCOG) and widely adopted by municipalities in the Dallas-Fort Worth region. Communities that have adopted the NCTCOG iSWM Criteria Manual use it as the basis for post-construction BMP design, performance standards, and maintenance documentation. iSWM is the standard for post-construction stormwater compliance in much of North Texas, making familiarity with its criteria essential for developers and property owners in the DFW region.

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.
