Construction Stormwater Permitting — TPDES CGP (TXR150000)

Construction stormwater permitting is the set of requirements that apply to stormwater discharges associated with construction activity, typically including:

• Determining whether your site must obtain CGP coverage (based on acres disturbed and “common plan of development”)
• Preparing and implementing a SWPPP (Stormwater Pollution Prevention Plan) (often called an SWP3 in Texas practice)
• Filing the right authorization paperwork (e.g., NOI or CSN) and maintaining required onsite documentation
• Performing and documenting inspections and corrective actions (BMP maintenance, repairs, upgrades)

In Texas, the governing permit for most construction projects is the 2023 Construction General Permit TXR150000 administered by TCEQ.

Construction stormwater permitting is commonly required when a project disturbs 1 acre or more, or when it is part of a larger common plan of development that cumulatively disturbs 1 or more acres. It is also frequently needed for projects pursuing construction financing, since banks and equity partners often require SWPPP and Construction General Permit (CGP) compliance as a funding condition. Projects located in or near an MS4 jurisdiction may face additional local stormwater oversight, with cities and local programs verifying SWPPP and BMP implementation during construction. Proper permitting also helps reduce exposure to sediment discharges, neighbor complaints, inspection findings, and other issues that can delay project schedules.

ESE Partners supports owners, developers, and general contractors across Houston, Dallas–Fort Worth, Austin, and San Antonio with construction stormwater permitting designed for real project schedules. Our deal-speed execution provides fast turnarounds for SWPPP/SWP3 preparation and submittal support to help avoid mobilization delays. We emphasize practical compliance through right-sized BMPs that control risk without overdesigning costs, along with field-first support such as inspection-ready documentation, corrective action tracking, and defensible records. With Texas regulatory fluency, ESE builds stormwater permitting strategies around TCEQ’s CGP TXR150000 framework and applicable local MS4 expectations.

1. Screen applicability (acreage disturbed + “common plan,” discharge points, receiving waters)
2. Define operators and responsibilities (owner/developer vs. GC vs. subcontractors; signatory roles)
3. Prepare SWPPP/SWP3 (site map, sequencing, BMP selection, stabilization strategy, maintenance triggers)
4. Support NOI/CSN pathway (confirm which filing applies and assemble the required package)
5. Implement BMPs & train field teams (what to install, when, and how to document it)
6. Conduct inspections & reporting (and manage corrective actions before they become findings)
7. Close out (final stabilization, termination documentation as applicable)

Key regulatory drivers for construction stormwater permitting typically include the TCEQ TPDES Construction General Permit TXR150000, also known as the 2023 CGP, which serves as the primary statewide authorization for construction stormwater discharges in Texas. Projects may also need to account for Municipal Separate Storm Sewer System (MS4) programs, where local requirements and enforcement interfaces can influence construction oversight, inspections, and BMP expectations. At the federal level, Texas’ CGP is issued under TPDES, the state’s implementation of the Clean Water Act stormwater permitting program, and is aligned with broader NPDES permitting concepts.

Skipping or under-executing construction stormwater permitting can create:

• Project delays: failed inspections, rework, and administrative hold-ups
• Enforcement exposure: citations, penalties, or mandated corrective actions
• Lender friction: missing SWPPP/permit coverage can become a closing condition or trigger noncompliance
• Third-party claims: sediment impacts and neighbor complaints that escalate costs and timeline uncertainty

ESE Partners is built for high-velocity projects where environmental compliance must support construction, not stall it. Our Texas-first execution model provides statewide capability for construction stormwater permitting and related compliance needs. With integrated service lines beyond stormwater, including environmental due diligence, remediation support, compliance, natural and cultural resources, and building sciences, ESE helps clients manage project risks through one coordinated team. Our responsive teams communicate clearly with owners, lenders, and construction leadership, keeping stakeholders aligned as schedules move. We also provide defensible documentation designed to stand up if a project receives scrutiny from regulators, municipalities, or other reviewing parties.
