## 3. Complete Technical Glossary (14 Core Terms)

1. **UST vs. AST (Storage Tank Comparison):** Underground Storage Tanks (USTs) store fuel sub-surface to preserve forecourt real estate under TCEQ TAC 334. Aboveground Storage Tanks (ASTs) sit on surface slabs with lower installation CapEx and visual inspection under EPA SPCC rules (40 CFR Part 112).
2. **Underground Storage Tank (UST):** A tank and connected underground piping system with at least 10% of its combined volume below ground. Regulated under TCEQ Title 30 TAC Chapter 334 and EPA 40 CFR Part 280; requires double-wall containment, ATG monitoring, and certified Class A/B/C operators.
3. **Aboveground Storage Tank (AST):** Stationary surface-mounted atmospheric vessel for bulk fuel or chemical storage built to UL 142 or UL 2085, NFPA 30/30A, and STI SP001 standards.
4. **TCEQ Title 30 TAC Chapter 334:** Primary Texas state regulatory code governing registration, secondary containment, release detection, operator training, financial assurance, and closure of USTs and ASTs.
5. **Spill Prevention, Control, and Countermeasure (SPCC) Plan:** Mandatory EPA document (40 CFR Part 112) for facilities storing >1,320 gallons of aggregate aboveground oil/fuel; requires PE certification every 5 years and 110% secondary containment volume.
6. **UL 142 vs. UL 2085:** UL 142 covers atmospheric steel tanks without thermal insulation; UL 2085 covers insulated protected tanks passing 2-hour 2,000°F fire, bullet, and vehicle impact tests.
7. **Fireguard® vs. Flameshield®:** STI Fireguard® uses porous concrete insulation between double steel walls to meet UL 2085; STI Flameshield® uses tight-wrap double steel walls meeting SwRI 97-04 2-hour fire endurance.
8. **Phase I Environmental Site Assessment (Phase I ESA):** Non-invasive historical and visual investigation under ASTM E1527-21 and EPA AAI (40 CFR Part 312) to identify Recognized Environmental Conditions (RECs).

10. **Recognized Environmental Condition (REC):** Presence or likely presence of hazardous substances or petroleum products in subsurface media due to a historical or active release (ASTM E1527-21).
11. **Stage I Vapor Recovery:** Closed-loop coaxial/dual-point vapor capture system returning displaced gasoline vapors from USTs to the delivery tanker truck during fuel drops; requires annual pressure decay testing under 30 TAC Chapter 115.
12. **Stage II Vapor Recovery & Decommissioning:** Dispenser-level vapor recovery system largely decommissioned in Texas under 30 TAC §115.241 and PEI RP500 due to modern vehicle Onboard Refueling Vapor Recovery (ORVR).
13. **Automatic Tank Gauge (ATG):** Digital console (e.g., Veeder-Root TLS-450PLUS) and tank probe system executing automated 0.2 GPH monthly leak tests, water ingress monitoring, and sump sensor alarms.
14. **Notice of Violation (NOV):** Formal TCEQ/EPA administrative enforcement citation requiring corrective remediation within 30–60 days to avoid penalties exceeding $10,000/day or fuel delivery lockouts.
15. **Hydrostatic Sump & Spill Bucket Testing:** Triennial liquid-level integrity testing under PEI RP1200 and 30 TAC §334.48 to verify spill buckets and containment sumps are liquid-tight.
16. **Cathodic Protection (CP):** Sacrificial anode or Impressed Current (ICCP) electrochemical corrosion protection for underground steel components (NACE SP0285, 30 TAC §334.49).
17. **Aluminum Composite Material (ACM Fascia):** Class A fire-rated aluminum composite cladding panels coated with Kynar 500® PVDF for durable, hurricane-rated gas station canopy fascia.
