Questions and Answers

Based upon the Q&A below, there is no change in the requirement other then the due date as stated in Amendment 01.

Q1- 1.3 – What documents will meet the requirement for certification of clean oil delivery truck and storage tank? Note that we may want to clean the tank “in house”, what documentation would be required in that case?

A1 - ONE OPTION WOULD BE A SIGNED LETTER DESCRIBING THE APPROVED CLEANING METHOD, WITH

PICTURES OF EACH TANK BEFORE, DURING THE PROCEDURE, AND AFTER.

Q2 - 1.4.1.1 – Are there alternative tank cleaning procedures that are acceptable for cleaning the truck and storage tank?

A2 - YES. EITHER CLEANING WITH DIESEL (FREE OF BIODESEL) OR STEAM CLEANING AND DRYING ARE

ACEPTABLE METHODS.

Q3 - 1.4.1.1 – Would it be acceptable to fill the delivery truck tank trailer & storage to total capacity with diesel fuel, then drain that fuel and blow down the tank until it is dry?

A3 - ONLY IF THE DIESEL FUEL IS FREE OF BIODIESEL. UNFORTUNATELY, #2 DIESEL IS PERMITTED TO CONTAIN BIODIESEL WITHOUT EXPLICITLY SAYING SO. BIODIESEL LEAVES A RESIDUE THAT CAN BE

PROBLEMATIC.

Q4 - 1.4.1.1 – Would it be acceptable to steam clean the delivery truck tank trailer & storage and blow down the tank until it is dry?

A4 - YES, STEAM CLEANING WITH A PRESSURE WAND AND THEN DRYING TANK WOULD BE ACCEPTABLE.

Q5 - 2.2.3 – Table 1 under column “Chemical and Physical Characteristics” – the line addressing:

“Cleanliness, Reported per ISO 4406 as Iso Code Particle Count, for particles greater than 4, 6, and

14 m (c)”

The column:

“Requirements ISO 68 Oil” states:

“For Information Only”

Based on the “for information only” statement, there are no ISO cleanliness levels required for the delivered product? Therefore there is no on site filtration required?

A5 - CORRECT – NO ONSITE FILTRATION IS REQUIRED – PARTICLE COUNT IS JUST FOR INFORMATION – NO PARTICULAR CLEANLINESS IS REQUIRED – IF OIL IS *VERY* MUCH DIRTIER THAN NORMAL NEW OIL

HOWEVER (~24 AS THE FIRST NUMBER), THAT WOULD BE A RED FLAG FOR CONTAMINATION

CONCERNS AND MIGHT PROMPT FURTHER ANALYSIS.

Q6 - 3.1 – The statement “spill prevention must be set up and observed by the government prior to delivering any oil”, what form of spill prevention is required?

A6 - THE CONTAINMENT ONLY NEEDS TO BE BIG ENOUGH TO HOLD THE LARGEST SINGLE TANK OF OIL, AND THEY SET IT ON THE GROUND AND THEN DRIVE ONTO IT BEFORE ERECTING THE WALLS OF THE

CONTAINMENT.

Q7 3.1.3 – The statement, “Oil containment measures must be provided with any form of temporary storage”, what form of containment will be required.

A7 - SAME ANSWER AS 3.1

Q8 - How long do you anticipate testing of material to last with tanker truck on site?

A8 - The contract states up to three weeks for testing to be complete. This depends on the lab turnaround time, so it may be shorter but allow up to three weeks

Q9 - Instead of testing with tanker on site, can we send a few GLs of Lot samples prior to 3000GLs being delivered to the site?

A9 - No, we need to take samples from the tanker onsite. This is to confirm we are getting the right oil at the right cleanliness level into our system. This is to ensure the sample matches the tank/shipment and further reduces the risk of contamination in our tanks.
