~900 t criteria pollutants emitted at berth annually (scaled estimate)
120K+ below-median-income residents in surrounding communities

Port Overview¶
The Port of Corpus Christi is the largest crude oil export port in the United States — a position held since the 2015 lifting of the U.S. crude export ban. Operated by the Port of Corpus Christi Authority under CEO Kent Britton, the port handles approximately 170+ million short tons of cargo annually, predominantly liquid bulk (crude oil, refined petroleum products, LNG). The port's Ship Channel Improvement Project — a $625 million project completed in early 2025 — deepened the channel to 54 feet and widened it to 530 feet, enabling calls from fully loaded Suezmax tankers.
Corpus Christi is unique on this site: the port is scaling up on every metric. Crude export volumes, vessel calls, and infrastructure capacity are all increasing. The petrochemical corridor between Corpus Christi and Houston is Texas's Gulf Coast equivalent of Louisiana's Cancer Alley — a concentrated industrial landscape where port, refinery, and chemical operations compound.
While docked, the tankers that dominate Corpus Christi traffic run high-capacity auxiliary boilers for cargo discharge operations — generating disproportionate per-vessel emissions compared to container ships. Texas has the weakest state-level environmental regulatory framework for port emissions of any major U.S. state.
Who Is Affected¶
The communities surrounding the Port of Corpus Christi bear disproportionate environmental burden. Hillcrest, Oak Park, and Dona Park are historically Black and Hispanic neighborhoods on the refinery fenceline — documented sites of environmental health disparity. Corpus Christi's Westside and Northside have absorbed decades of industrial expansion.
| Community | Population | Key Health Burden |
|---|---|---|
| Hillcrest | 1,500+ | Historically Black neighborhood on refinery fenceline; documented asthma and cancer disparities |
| Oak Park | 3,500+ | Hispanic community adjacent to petrochemical operations |
| Dona Park | 2,000+ | Fenceline to refineries; documented heavy metal contamination |
| Corpus Christi Westside | 60,000+ | Historically Hispanic; port and refinery corridor exposure |
| Corpus Christi Northside | 40,000+ | Adjacent to port and Port Industries petrochemical area |
Environmental Justice
Corpus Christi's Westside and Northside — predominantly Hispanic working-class communities — have borne the cumulative environmental burden of the port's transformation into America's largest crude export terminal. Texas has no state environmental justice legislation, no mandatory community air monitoring, and no state-level emissions reporting for port operations. The Alabama-Coushatta Tribe of Texas is the closest federally recognized tribe; the Coastal Bend was historically Karankawa territory.
Community Health Profile¶
CDC PLACES data for Nueces County provides tract-level health estimates. Port- and refinery-adjacent tracts show elevated rates across every measured indicator:
| Health Measure | Port-Adjacent Tracts | Texas | National |
|---|---|---|---|
| Current asthma among adults | 10.5% | 9.0% | 9.6% |
| COPD among adults | 8.0% | 5.9% | 6.4% |
| Coronary heart disease | 7.8% | 6.1% | 5.7% |
| Depression among adults | 22.5% | 17.5% | 20.5% |
| Obesity among adults | 40.5% | 34.8% | 33.0% |
| Fair or poor self-rated health | 23.0% | 19.2% | 17.5% |
| High blood pressure | 38.5% | 31.2% | 32.5% |
Port-adjacent Nueces County tracts exceed Texas state averages across every indicator, with COPD (+2.1 pp) and obesity (+5.7 pp) showing the sharpest gaps. EPA's Toxics Release Inventory identifies 50+ TRI-reporting facilities in Nueces County — a density reflecting the concentration of refining, petrochemical, and terminal operations.
Health Impact Analysis¶
Using ICCT Port Emissions Screening data and EPA's concentration-response methodology. Corpus Christi's tanker-dominated traffic profile means shore power is largely infeasible; barge-mounted capture is the only viable at-berth control technology.
| Health Outcome | Current Annual Burden | With At-Berth Capture |
|---|---|---|
| PM2.5 emissions at port (tonnes/yr) | ~280 t (scaled estimate) | 69–99% reduction |
| NOx emissions at port (tonnes/yr) | ~500 t (scaled estimate) | Up to 95% reduction |
| Premature deaths from port PM2.5 | Estimated 12–30/year | 8–28 lives saved/year |
| Cardiovascular & respiratory hospitalizations | Estimated 45–125/year | 32–120 avoided/year |
| Childhood asthma ED visits | Estimated 65–180/year | 46–170 avoided/year |
| Monetized public health benefit (EPA VSL) | $55M+/year | $38–$55M saved/year |
Methodology Note
Emissions estimates scaled from ICCT Port Emissions Screening data with adjustment for tanker dominance (tanker boilers have distinct emission profile vs container auxiliary engines) and the 54-foot channel deepening completed in 2025. The Port of Corpus Christi Authority has not published a comprehensive port-wide emissions inventory.
The Regulatory Gap¶
California's CARB At-Berth Regulation has been in effect since 2014 and was authorized by EPA under the Clean Air Act in October 2023. Texas has not adopted at-berth vessel emission controls, has no equivalent rulemaking underway, and has the weakest state environmental regulatory framework for port operations of any major U.S. state.
The Texas Commission on Environmental Quality (TCEQ) has legal authority to address port emissions but has not initiated rulemaking. TCEQ's historical regulatory posture prioritizes industry accommodation — a stance consistently documented in regulatory assessments over multiple administrations. At Corpus Christi specifically, TCEQ has not conducted a comprehensive port-area health impact assessment.
Pathways to Action
- Port Authority voluntary commitment: Port of Corpus Christi Authority could require at-berth controls as a condition of terminal operating agreements
- Channel deepening operating conditions: The recently completed $625M Ship Channel Improvement Project creates leverage points in terminal operating terms
- Federal EPA Clean Ports funding: The $3 billion Clean Ports Program (IRA Section 60102) included Gulf Coast awards — disbursement status requires FOIA verification
- Crude export supply chain engagement: Major crude shippers through Corpus Christi may face Scope 3 emissions requirements from international buyers
- Community advocacy through Hillcrest, Oak Park, Dona Park: Established environmental advocacy infrastructure exists and has leveraged federal EJ frameworks

The Opportunity
At-berth emissions capture at the Port of Corpus Christi could save 8–28 lives per year, prevent up to 120 hospitalizations, and deliver $38–$55 million annually in monetizable health benefits. The recently completed channel deepening makes Corpus Christi the most immediate growth story on this site — every metric is increasing. Without at-berth controls, the port's competitive advantage translates directly into increasing community emissions burden.
Interactive Dashboard¶
An interactive dashboard for this port — wind rose, CDC PLACES health indicators, EPA TRI facility burden, and at-berth emissions visualizations — is in development and will be released as the port-specific data harvest pipeline comes online.
