1. EXECUTIVE SUMMARY & SCOPE

1.1 Purpose

This Standard Operating Procedure (SOP) defines the mandatory protocol for generating, authorizing, issuing, and reconciling Purchase Orders (POs) for fuel station inventories (gasoline, diesel, alternative fuels, and forecourt lubricants). Strict adherence ensures regulatory compliance with EPA, OSHA, and local weights and measures standards, maintains chain-of-custody tracking, mitigates financial exposure through dynamic pricing verification, and prevents stockouts.

1.2 Scope

This procedure applies to all corporate-owned, franchised, and contractor-operated fueling sites managed or audited under the Template Registry framework. It covers bulk fuel deliveries, emergency spot purchases, lubricant replenishment, and additive procurement. It does not cover non-fuel convenience store (C-Store) merchandise.

2. PREREQUISITES & REQUIRED TOOLS

2.1 Software & Systems

• Enterprise Resource Planning (ERP) / Procurement Module: SAP, Oracle Cloud SCM, or PDI Enterprise (configured with automated fuel module extensions).
• Automated Tank Gauge (ATG) System: Veeder-Root TLS-450Series or equivalent (for real-time ullage verification).
• Template Registry Asset: TR-FS-PO-v3.xlsx (Standardized Electronic Purchase Order Template).

2.2 Compliance & Safety Standards

• NFPA 30: Flammable and Combustible Liquids Code.
• EPA 40 CFR Part 280: Technical Standards and Corrective Action Requirements for Owners and Operators of Underground Storage Tanks (USTs).
• Chain of Custody: Bill of Lading (BOL) verification protocols.

2.3 Required Equipment

• Encrypted mobile data terminal or secure desktop workstation.
• Calibrated dipstick or digital probe verification access.

4. STEP-BY-STEP PROCEDURE

Phase 1: Inventory Assessment & Demand Forecasting

• Access the Automated Tank Gauge (ATG) system to pull current inventory levels (Gross Volume, Temperature-Compensated Volume, and Water Level).
• Calculate available ullage (empty tank capacity) for each fuel grade (e.g., Regular Unleaded, Premium, Ultra-Low Sulfur Diesel) ensuring the mandatory 10% safety headspace is respected.
• Cross-reference current tank levels with the 7-day rolling sales velocity report via the PDI Enterprise module.
• Confirm replenishment threshold has been breached (e.g., inventory drops to $\le 30%$ total capacity).

Phase 2: Template Initialization & Data Input

• Open the standardized electronic template: TR-FS-PO-v3.xlsx.
• Input Station Header Data: Station ID, Physical Address, EPA Tank Registration Numbers, and Date/Time of issuance.
• Enter Vendor Details: Approved Fuel Supplier Name, EPA Vendor Certification ID, Terminal Rack Source Code, and Contract Pricing Tier.
• Populate Line-Item Details:
  • Fuel Grade / ASTM Specification (e.g., ASTM D4814 for Gasoline, ASTM D975 for Diesel).
  • Quantity ordered in Net Gross Gallons (compensated to $60^\circ\text{F}$).
  • Contracted rack price per gallon plus applicable freight, taxes (FET, LUST, state/local excise), and environmental fees.
• Calculate total capital commitment: $\text{Total Cost} = (\text{Net Gallons} \times [\text{Rack Price} + \text{Freight} + \text{Taxes}]) + \text{Additives}$.

Phase 3: Verification & Multi-Tier Approval Workflow

• Level 1 Check: Inventory Controller validates that the requested volume does not exceed available tank ullage (prevents overfill conditions).
• Level 2 Check: Finance Director verifies budget allocation and credit line availability with the specified fuel distributor.
• Secure digital signatures on the PO document within the ERP workflow engine.
• Generate the final, un-editable PDF version of TR-FS-PO-v3.xlsx carrying a cryptographically secure PO Number.

Phase 4: PO Transmission & Vendor Acknowledgment

• Transmit the approved PO via Electronic Data Interchange (EDI 850) or secure vendor portal.
• Require formal vendor acknowledgment (EDI 855) within 2 hours of transmission, confirming price lock, product availability, and estimated delivery window (ETA).
• Archive the confirmed PO and vendor response in the station's permanent compliance repository.

5. QUALITY ASSURANCE & VERIFICATION

5.1 Key Metric Thresholds

• Ullage Safety Margin: Deliveries must never exceed $90%$ of total tank capacity to prevent catastrophic overfills.
• Price Variance Tolerance: Invoiced price must match the PO contract rate within a $\pm $0.0000$ variance tolerance (exact match required for rack-plus contracts).
• Delivery Execution Window: Delivery must occur within $\pm 2$ hours of the confirmed ETA.

5.2 Common Operational Pitfalls

• Temperature Incompendation: Failing to account for thermal expansion/contraction of fuel, leading to volume discrepancies during offloading.
• Orphaned POs: Issuing spot-market fuel purchases without checking existing rack contract allocations, resulting in premium spot pricing penalties.
• Failure to Reconcile BOL: Offloading fuel without matching the Bill of Lading grade and quantity directly against the issued PO line items.

5.3 Audit Checklist (Monthly Review)

• 100% of physical deliveries reconcile against an authorized PO ID.
• ATG reconciliation logs match the quantities stated on the PO and BOL.
• Tax exemptions (if applicable, e.g., government/fleet) are accurately reflected on the PO financial breakdown.

6. TROUBLESHOOTING FAQ

Q1: What action is required if the fuel distributor delivers a different volume than specified on the PO due to transport capacity constraints?

A: If the delivered volume is less than the PO, accept the delivery, record the actual gallons dropped on the BOL, and issue a PO amendment in the ERP system to adjust the financial liability downward. If the volume exceeds the PO and the tank ullage allows safely (< 90% capacity), accept the drop, verify the price tiering, and submit an expedited supplemental PO within 4 business hours. If tank ullage cannot safely hold the excess, halt the drop immediately and contact dispatch.

Q2: How should an emergency spot-market purchase be handled when the primary vendor cannot fulfill the PO within the required window?

A: Execute an Emergency Procurement Override within the ERP system. Select a pre-vetted secondary vendor from the Template Registry Approved Vendor List (AVL). Document the primary vendor's failure-to-supply notice in the PO remarks section. Apply the emergency spot-market pricing matrix in TR-FS-PO-v3.xlsx and route directly to the Finance Director for expedited (under 30 minutes) sign-off.

Q3: What is the protocol if a pricing discrepancy is discovered between the issued PO and the final vendor invoice?

A: Do not process the invoice for payment. Cross-check the PO contract tier against the daily spot rack index referenced in the supply agreement. If the vendor error is confirmed, issue a formal Disputed Invoice Notice through the procurement portal, requesting a corrected invoice matching the exact figures of the authorized PO.
