NOTES (Apply to Fungible and Segregated):
Th is
is a base gasoline, not for sale to the ultimate consumer.
Heavy Metals are not allowed to be present.
Any gasoline exhibiting an offensive odor and/or poses a personal health hazard will not be accepted for shipment. Any gasoline
containing more than 0.50 wt. % of dicyclopentadiene will not be accepted for shipment.
The referee method for oxygenates will be based on a gas chromatograph test.
Delivery test results may vary by the smaller of ASTM reproducibility for a given test or any test tolerance as allowed by state or EPA
regulations at the point of delivery.
1. All F grades may not contain oxygenates, such as ethers and alcohols. The use of non‐hydrocarbon blending
components in these grades is prohibited. Origin maximum MTBE .25 vol.%.
Delivery maximum MTBE .50 vol. %.
2. Refer to test methods published in 40 CFR Chapter 1, Part 80.46. Alternative aromatics and oxygenates test methods, ASTM
D1319 and ASTM D 4815, may be used according to federal and state regulations.
3. For products blended to meet EPA or state imposed summer VOC requirements, tests must be performed in accordance
with the procedures described in 40 CFR, Part 80.
4. Emissions reductions must be calculated using EPA guidelines.
5. Mercaptan Sulfur waived if fuel is negative by Doctor test.
6. Computer and Linear methods may be used to determine V/L value. D5188 will be the referee
method
7. Specifications must be met before blending of denatured fuel ethanol.
8. Oxygen content must meet a minimum of 1.7 wt.% and a maximum of 4.0 wt.% after blending of
denatured
fuel ethanol.
9. Refer to 40 CFR Part 80.195 (d)(2). Alternative sulfur test methods, ASTM D 5453 and D 7039, may
be used
according to federal and state regulations.
10. Woodbury and Linden facilities will only allow shipments of region 2 fuels.
Any Region 1 fuels shipped downstream of Aberdeen will be comingled with region 2 fuels
11. Refer to Colonial's current RVP schedule for cycle numbers.
