Section 404 CWA and Section 10 RHA Permits and Consultation in Texas

Section 404 of the Clean Water Act regulates the discharge of dredged or fill material into waters of the United States, including certain wetlands. The U.S. Army Corps of Engineers generally administers the Section 404 permitting program, with EPA guidelines informing environmental review for many permit decisions.

Section 10 of the Rivers and Harbors Act of 1899 requires authorization before work occurs in, over, under, or affecting navigable waters of the United States, including activities that may alter the course, location, condition, or capacity of those waters.

For Texas projects, these permits often apply to:

• Stream crossings
• Wetland impacts
• Roadway and utility extensions
• Pipeline and transmission corridors
• Dock, marina, pier, bulkhead, dredging, and shoreline work
• Industrial, energy, logistics, and port-related development
• Commercial real estate and master-planned development near jurisdictional waters

Depending on the activity, location, and level of impact, authorization may be available through a Nationwide Permit, Regional General Permit, Letter of Permission, or Individual Permit.

A Section 404 CWA or Section 10 RHA permit and consultation strategy may be needed when a project involves:

• Commercial real estate acquisition or development with wetlands, streams, ponds, drainageways, or mapped floodplain features
• Site grading, filling, excavation, or road construction that may affect jurisdictional waters or wetlands
• Utility, pipeline, fiber, transmission, or linear infrastructure crossings
• Bridge, culvert, outfall, bank stabilization, or stormwater infrastructure work
• Port, dock, bulkhead, dredging, marina, or coastal construction
• Lender due diligence where aquatic resource constraints could affect collateral value, development feasibility, or closing conditions
• Public infrastructure projects requiring federal authorization, state water quality certification, or agency consultation
• Energy and industrial projects where permitting risk could affect construction sequencing or capital deployment

In Texas, Section 404 permit actions commonly also require Section 401 water quality certification review. TCEQ conducts Section 401 certification reviews for many USACE Section 404 permit applications involving discharges of dredged or fill material into waters of the United States, including wetlands.

ESE Partners approaches Section 404 Clean Water Act (CWA) and Section 10 Rivers and Harbors Act (RHA) permitting with one goal: identifying the cleanest path to authorization without overcomplicating the deal or the design. Our team starts with early jurisdictional screening to identify wetlands, streams, navigable waters, and potential permitting triggers before design decisions become expensive. We develop practical permitting strategies that evaluate avoidance, minimization, Nationwide Permit eligibility, mitigation needs, and schedule implications, while communicating clearly with developers, engineers, lenders, attorneys, owners, and other project stakeholders so they understand the project’s risk profile. ESE also provides Texas-specific regulatory coordination with the appropriate U.S. Army Corps of Engineers district, TCEQ, and other reviewing agencies. Our defensible field documentation may include wetland delineations, waters assessments, impact exhibits, alternatives analysis support, and permit application packages. When applicable, we also support consultation related to threatened and endangered species, cultural resources, state water quality, coastal issues, and compensatory mitigation. We do not overcall risk; we help clients understand what is regulated, what is not, what can be avoided, and what needs to be authorized.

1. Project Kickoff and Desktop Review: ESE reviews site plans, survey data, aerial imagery, topography, soils, NWI mapping, FEMA data, hydrology, and prior environmental reports to identify potential aquatic resource constraints.
2. Field Assessment and Delineation: Our team evaluates wetlands, streams, drainage features, ordinary high water marks, riparian corridors, and potentially jurisdictional features using accepted field methods.
3. Jurisdictional Strategy: ESE determines whether the project may require a Section 404 permit, Section 10 authorization, jurisdictional determination, or agency coordination with USACE.
4. Impact Analysis and Avoidance Review: We work with civil engineers, surveyors, and project designers to quantify impacts and identify practical avoidance and minimization options.
5. Permit Pathway Selection: ESE evaluates whether the project may qualify for a Nationwide Permit, Regional General Permit, Letter of Permission, or Individual Permit.
6. Application Preparation and Agency Coordination: Our team prepares permit narratives, figures, impact tables, alternatives documentation, mitigation concepts, pre-construction notification materials, and agency submittals.
7. Consultation and Supporting Studies: When required, ESE supports Endangered Species Act Section 7 consultation, National Historic Preservation Act Section 106 review, TCEQ Section 401 certification, and other resource-agency coordination.
8. Permit Conditions and Construction Support: After authorization, ESE helps clients understand permit conditions, mitigation commitments, reporting requirements, construction constraints, and compliance obligations.

Section 404 CWA and Section 10 RHA permitting is often multi-layered, and ESE helps clients understand which requirements apply and how they may affect schedule, design, and constructability. Key regulatory drivers may include Clean Water Act Section 404, which regulates discharges of dredged or fill material into waters of the United States, including certain wetlands, and Rivers and Harbors Act Section 10, which applies to work in, over, under, or affecting navigable waters of the United States. These reviews are administered through the U.S. Army Corps of Engineers Regulatory Program, which evaluates activities affecting navigable waters and discharges into jurisdictional waters. Depending on the project, authorization may be available through Nationwide Permits, which cover categories of activities that meet specific terms, limits, and regional conditions. Clean Water Act Section 401 Water Quality Certification may also apply, with TCEQ reviewing many Section 404 permit actions in Texas to determine whether the proposed discharge will comply with state water quality standards. Additional consultation or review may be required under Endangered Species Act Section 7 when a federal permit action may affect listed species or designated critical habitat, and under National Historic Preservation Act Section 106 when a federal permit, approval, license, or funding action could affect historic properties. Compensatory mitigation requirements may also apply when unavoidable impacts to regulated aquatic resources remain after avoidance and minimization.

Skipping or delaying Section 404 CWA and Section 10 RHA permitting can create significant project risk, including:

• Construction delays if jurisdictional waters or wetlands are discovered late in design or during site work
• Permit violations from unauthorized fill, dredging, excavation, or work in navigable waters
• Lender concerns when environmental due diligence does not address aquatic resource permitting constraints
• Design rework if impacts are not quantified early
• Mitigation cost surprises for unavoidable wetland or stream impacts
• Agency enforcement exposure for unauthorized impacts
• Transaction risk if environmental constraints affect development feasibility, timing, or closing conditions

For commercial real estate, energy, industrial, and infrastructure projects, the permitting question is not only “Can we get approval?” It is also “How does this affect schedule, cost, design, and deal certainty?”
