ODEQ Air Permits and Emissions Monitoring for Refineries
Tulsa refineries including HollyFrontier and Phillips 66 operations are subject to Oklahoma Department of Environmental Quality (ODEQ) air quality regulations and federal Clean Air Act requirements. Title V operating permits, minor source permits, and state-only air quality rules govern emissions of sulfur dioxide, nitrogen oxides, volatile organic compounds, and particulate matter from crude distillation, catalytic cracking, coking, and alkylation units.
iSi Environmental manages your facility's air permit portfolio, calculating potential emissions from each process unit, evaluating best available control technology (BACT) for new or modified sources, and preparing permit applications for ODEQ submission. We maintain current operating permits, respond to ODEQ information requests, and ensure your facility's monitoring and record-keeping systems meet regulatory requirements.
Our team stays current with ODEQ's evolving air quality standards and Oklahoma's ongoing implementation of federal air regulations. Whether your facility is applying for a new Title V permit or modifying existing operations, we handle the technical analysis, regulatory correspondence, and compliance documentation.
SPCC Plans and Hazardous Waste Compliance
Spill Prevention Control and Countermeasure (SPCC) plans protect waterways by requiring petroleum storage facilities to prevent and plan for spill events. For Tulsa refineries and pipeline operations storing crude oil, refined products, or hazardous substances, SPCC compliance is non-negotiable. Plans must include secondary containment design, overfill alarms, inspections, employee training, and spill response procedures.
iSi Environmental develops facility-specific SPCC plans that address your unique storage configuration, process hazards, and proximity to water bodies. We also manage hazardous waste documentation (generator status, manifests, disposal records) and help your facility stay compliant with EPA and Oklahoma Department of Environmental Quality hazardous waste rules. Our team coordinates triennial SPCC recertification by licensed professional engineers and ensures all staff receive annual training.
Underground Storage Tank (UST) and Pipeline Compliance
Many Tulsa oil & gas facilities operate underground storage tanks for crude oil, refined products, or waste oils installed decades ago—before current regulatory standards. Oklahoma UST regulations require monthly leak monitoring, tank inspections, cathodic protection, spill and overfill prevention, and closure procedures. Non-compliant systems can trigger expensive remediation, environmental fines, and operational shutdowns.
We assess your facility's UST inventory, identify compliance gaps, and develop realistic upgrade or closure plans. For pipeline operations, we help ensure your facility's secondary containment, overfill prevention, and emergency response procedures meet ODEQ and federal DOT standards. We also manage Tier II hazardous chemical reporting, ensuring your facility meets deadline and disclosure requirements under federal EPCRA regulations.

Frequently Asked Questions
What are the ODEQ air permitting requirements for Tulsa refineries? +
Oklahoma Department of Environmental Quality (ODEQ) requires air permits for refineries and petrochemical facilities that emit regulated pollutants including sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs). Tulsa refineries must obtain Title V operating permits (federal requirement under the Clean Air Act) and may require minor source permits for specific equipment. ODEQ also enforces state-only regulations for emissions from crude distillation, catalytic cracking, and product loading. Our team handles permit applications, emissions calculations, best available control technology (BACT) analysis, and compliance monitoring to keep your facility current with ODEQ and EPA standards.
What does an SPCC plan include for petroleum facilities? +
Spill Prevention Control and Countermeasure (SPCC) plans are required for facilities storing more than 1,320 gallons of oil in any single aboveground storage tank or 10,000 gallons total. An SPCC plan includes: facility layout and secondary containment design, spill prevention measures (tank inspection schedules, overfill alarms), spill response procedures and personnel assignments, cleanup materials and equipment staging, and regular employee training. For Tulsa refineries and pipeline operations, the plan must address the unique hazards of crude oil, refined products, and used oils. We develop facility-specific SPCC plans, oversee regular training, and manage triennial professional engineer certifications as required by EPA rules.
What underground storage tank compliance is required in Tulsa? +
Oklahoma underground storage tank (UST) regulations require monthly tank monitoring for leaks, regular inspections of tank integrity, cathodic protection systems for steel tanks, spill and overfill prevention equipment, corrosion protection, and closure procedures when tanks are taken out of service. Tulsa oil & gas operations often have legacy USTs installed decades ago that may not meet current standards. We assess tank age, material condition, compliance history, and regulatory exposure. For non-compliant systems, we develop upgrade or closure plans that minimize regulatory penalties and operational disruption. Our team coordinates with ODEQ for tank registration updates and closure documentation.
