Operating a chemical facility in the Houston-Galveston-Brazoria region means navigating one of the world's most intense and complex environmental regulatory environments. Proactive, systematic management is not merely about compliance, it is essential for operational continuity, risk mitigation, and maintaining the social license to operate in this vital economic region. This checklist provides a foundational framework for key compliance areas, grounded in the specific realities of local regulations and enforcement priorities.
The goal is not to react to violations, but to build systems that prevent them.
The Houston Context: A Higher Standard
High Regulatory Density: The Houston area is home to over 1,000 chemical manufacturing plants and refineries, leading to heightened scrutiny from the Texas Commission on Environmental Quality (TCEQ), the Environmental Protection Agency (EPA) Region 6, and local entities like the Harris County Pollution Control Department.
Enforcement Priority: The EPA has identified the Houston region as a priority area for reducing toxic air pollution. In recent enforcement initiatives, the EPA and DOJ have secured multi-million dollar settlements with Houston-area chemical companies for Clean Air Act violations, emphasizing the severe financial and operational risks of non-compliance.
Comprehensive Management Checklist
Air Quality Compliance
-
Permits & Modeling: Verify all active permits (New Source Review, PSD, Title V) are current and site operations align with permitted capacities. Ensure dispersion modeling is updated with latest TCEQ-approved models.
-
Leak Detection & Repair (LDAR): Implement a robust, documented LDAR program per 40 CFR Part 63, Subparts F, G, H, or UU for applicable processes. (EPA LDAR requirements are strictly enforced for chemical plants).
-
Flare & Vent Management: Monitor and record flare operations (combustion efficiency, vent gas composition) to ensure compliance with 40 CFR §60.18 or §63.11 and avoid "smokeless flare" violations.
-
Fenceline Monitoring: For facilities producing or using benzene, ethylene oxide, or 1,3-butadiene, review requirements for fenceline monitoring under TCEQ rules and EPA's National Air Toxics Trends Stations (NATTS) priorities.
Water Quality & Stormwater Management
-
NPDES Permits: Confirm compliance with individual or multi-sector general permit (TXR050000) for process water and stormwater. Benchmark monitoring for sector-specific pollutants is critical.
-
SWPPP Integrity: Ensure the Stormwater Pollution Prevention Plan is a living document, updated for site changes, with weekly and quarterly inspection records fully documented.
-
Spill Prevention (SPCC & FRP): Maintain a Professional Engineer-certified SPCC Plan. If storage thresholds are met, a Facility Response Plan (FRP) is also required under the Clean Water Act.
Hazardous Waste (RCRA) Operations
-
Waste Characterization: Document the process for determining if wastes are listed (F, K, U, P) or characteristic (D-codes). Misclassification is a common violation.
-
Container & Tank Management: Inspect hazardous waste accumulation areas weekly per 40 CFR §262.16(b)(3). Ensure containers are labeled, dated, and closed.
-
Biennial Reporting: Confirm accurate and timely submission of the EPA Form 8700-13 A/B.
Emergency Preparedness & Community Engagement
-
Risk Management Plan (RMP): Review and update the RMP under 40 CFR Part 68 every five years or after a significant change. Ensure emergency response coordination with local agencies.
-
Tier II Reporting: Annually submit chemical inventory reports (SARA Title III) to TCEQ, the local fire department, and the Local Emergency Planning Committee (LEPC).
-
Public Transparency: Proactively engage with neighboring communities, especially in areas identified by the EPA's EJSCREEN tool as having potential environmental justice concerns.
Recordkeeping & Internal Auditing
-
Centralized System: Maintain a secure, organized system for all permits, monitoring data, training records, inspection logs, and correspondence with agencies.
-
Third-Party Audit: Schedule an annual or bi-annual compliance audit by an independent third party to identify gaps before regulators do.
Conclusion: Building a Resilient Operation
For Houston's chemical industry, meticulous environmental management is inseparable from business resilience. This checklist is a starting point for a culture of continuous review and improvement. By systematically addressing these areas, facilities can better manage risk, avoid catastrophic penalties, and demonstrate leadership in an industry critical to both the local economy and the national supply chain.
