About this file

This is a technical specification attachment for a Tank Cleaning contract opportunity in South Carolina, establishing fuel quality standards that must be met by the service provider. The document references ASTM D975, the Standard Specification for Diesel Fuel Oils, as the mandatory minimum standard for all fuel that is tested and treated under this contract. The specification covers fourteen distinct test parameters that fuel must meet, including flash point (minimum 125°F), appearance (clear and bright at 75°F), water and sediment content (maximum 0.05% volume), carbon residue (maximum 0.20%), API gravity (range 30.0-39.0), distillation characteristics (minimum 540°F, maximum 640°F at 90% recovery), viscosity (range 1.90-4.10), sulfur content (maximum 1.0%), corrosion rating (maximum #3), residue at end point (maximum 3.0%), particulate contamination (maximum 10 Mg/L), cetane index (minimum 40), accelerated storage stability (maximum 3.0 Mg/L), and microbial contamination (none allowed).

The technical requirements apply to both #1 and #2 diesel fuel grades and are designed to ensure safe handling, storage, complete combustion, proper engine performance, and extended fuel shelf life. No pricing, award timeline, contract term, or other commercial terms are specified in this attachment, which functions solely as a technical compliance document for bidders to understand the fuel quality standards required under the tank cleaning contract.

ATTACHMENT D

Fuel MUST be tested and treated to the minimum standards of the latest edition of ASTM D975 – Standard Specification for Diesel Fuel Oils.

ASTM D975 — Diesel Fuel Specifications (Following excerpts from ASTM D975 provided for reference only :)

Test Parameters : Implications and Uses Specifications

Flash Point: (D93) in degrees F. The minimum temperature at which fuel vapors will ignite under a low flame. Important for safe handling and storage.

125°F -= Minimum for #2 Diesel Fuel

Appearance: @ 75° F is a visual examination of the fuel. Dark and/or cloudy fuel suggests a need for remediation.

"Clear and Bright"

Water and Sediment: shows the level of contamination by water and sediments (D1796, D1744 and D2709).

0.05 maximum, % volume

Carbon Residue: (D524) a measure of the carbon depositing tendencies of a fuel when heated in a bulb under prescribed conditions.

0.20 maximum

API Gravity: @ 60°F is the density of the fuel. Deviation from the normal range will alter the classification of the fuel for its intended use.

Range: 30.0 — 39.0

Distillation: (D86) process by which the fuel is distilled and recovered at specified levels. Defines its evaporation characteristics; is important for complete combustion.

540°F = minimum

640°F = maximum

@ 90% recovered

Viscosity: (D445) the measure of resistance to flow of a liquid;

important for consistency, injector flow, and good atomization.

Range: 1.90 — 4.10

Sulfur: (D5453) a measure of sulfur content. Important to minimize engine wear and to meet legislation.

1.0 maximum

Corrosion: (D130) rates the tendency for fuel to attack metal surfaces in the distribution and storage network, and in the engine fuel system.

#3 = maximum

Residue at End Point: in per cent suggests contamination of the fuel by higher boiling compounds.

3.0% = maximum

Particulate Contamination: in Mg/L is the level of solid particulate matter recovered from the fuel which can lead to blockage of the fuel flow, starvation of and damage to the fuel pump, and damage to the diesel engine.

10 Mg/L = maximum

Cetane Index: (D976) shows the ability of the fuel to ignite properly. Specified as a limitation on the amount of high aromatic components.

40 = minimum

Accelerated Storage Stability: (D5304) a procedure for assessing the potential long-term storage stability. Using oxygen over pressure at a specified temperature for a set period of time to simulate the degradation of the fuel on standing.

3.0 Mg/L= maximum For

grades :

#1 Diesel fuel

#2 Diesel fuel

Microbial Contamination: (D6469) the level of a variety of algae growth in the fuel which blocks the flow of fuel by filter blanking and degrades the quality of the fuel.

None Allowed
