Tesoro Logistics Northwest Terminalling Company LLC Product Quality Control Guidelines

Tesoro Logistics Northwest Terminalling Company LLC Product Quality Control Guidelines For All Products Bound for NWTC Storage Effective 06/19/2013

PRODUCT QUALITY CONTROL Scope It is Tesoro Northwest Terminalling Company s intent to meet or exceed the Product Quality requirements of its customers. To be able to achieve this end, Tesoro Northwest Terminalling Company (NWTC) has implemented a product quality-control procedure for product shipped to NWTC terminals. Complete product specifications that all shippers will be required to meet are shown in Attachment 1. Certificate of Analysis Product Quality Methods Tesoro NWTC shall require a Certificate of Analysis (C of A) for all products received into our Terminals. Tesoro NWTC will receive the C of A via the LGSTC C of A process which requires this document for every batch shipped on the Pipeline. For Denatured Ethanol receipts into NWTC Terminals a C of A must accompany the bill of lading. Tesoro NWTC will obtain the same samples as described in the next section and will test for key properties with field analyzers to confirm the correct product was shipped and delivered. Please note that for all Ultra Low Sulfur Diesel Fuels (ULSD) we will test 100% of all product received for sulfur content. Tesoro NWTC s quality assurance program is composed of three main components, namely: Sampling Procedures Testing Procedures Action Plans Aviation Tank Inspection Each Aviation tank is to be opened and visually inspected every 3 years. If cleaning is needed the tank will be cleaned before returning to service. Sampling Procedures Retention: Tank Sampling All terminal receipt samples will be retained for 30 days unless otherwise notified. Tanks will be sampled after each batch receipt or at least monthly using ASTM D 4057 Standard Practice for Manual Sampling of Petroleum and Petroleum Products to obtain representative samples of the product. As an alternative, composite samples of batches being delivered to the terminal tank may be used to represent product received into the tank. Ethanol Receipts from trucks will be randomly sampled and tested. Tank Composites Samples are to be collected and tested on a bi-weekly basis. ULSD receipts are to be to isolated tanks and a composite sample is to be collected and tested before the tank is to be opened up to the rack. In locations where having isolated tanks is impractical, i.e. tanks on running gauge to the truck rack, the following process is to be used: Incoming product is to be sampled and tested for sulfur within the first 15 minutes of the receipt June 2013 Page 2 Quality Control Guidelines

PRODUCT QUALITY CONTROL Pull and Test spot Pipeline delivery samples as practical during normally staffed business hours throughout the delivery. Upon completion of every delivery or sequence of deliveries, a composite sample from each ULSD tank must be obtained and tested individually. Marine Vessels (Barges) Testing Procedures Each barge compartment will be sampled and visually checked, the samples will be composited for each shipped and product grade, prior to discharge, using ASTM D 4057 Standard Practice for Manual Sampling of Petroleum and Petroleum Products. Marine Vessels (Barges) Upon Arrival At Pasco All testing is performed on a blended compartment composite sample for each product grade, before discharging to shore tankage (see Attachment 3 for Process to Evaluate Field Testing Results): ULSD Other Diesels Gasoline Ethanol Jet Visual Visual Visual Visual Clear and Bright API Gravity API Gravity API Gravity API Gravity API Gravity Flash Flash Octane Acidity Color Sulfur RVP Water Content Flash Point (TCC) Microseparometer (MSEP) Terminals This testing is performed on each pipeline / barge batch after it is received into a tank or on a composite sample from the receiving line at NWTC Terminals. ULSD product tank samples and/or spot samples are to be tested for sulfur immediately after they are obtained. The following tests will be performed (see Attachment 3 for Process to Evaluate Field Testing Results): ULSD Other Diesels Gasoline Ethanol (By Truck) Jet* Visual Visual Visual Visual Clear and Bright API Gravity API Gravity API Gravity API Gravity API Gravity Flash Flash Octane Acidity Color Sulfur RVP Ethanol content (quarterly GC)* Flash Point (TCC) Water content Distillation + Freeze Point + Microseparometer (MSEP) Note *: Run by outside laboratory at Boise or by Pasco Terminal Laboratory. Note +: Not run on Jet batches continuing on to Spokane. FULL TESTING A Full Test will be performed when a fungible storage tank is off-spec or when it can be reasonably assumed that there are problems with product quality. This testing includes all tests shown on the ASTM specification through a non- NWTC affiliated testing lab. June 2013 Page 3 Quality Control Guidelines

PRODUCT QUALITY CONTROL Test Records FULL TESTING CONFIRMATION TESTING Action Plans Situations 1. Product found, as a result of our quality assurance testing, not meeting the NWTC Specifications, in a barge compartment, or a NWTC tank. Results of full testing by an outside laboratory will be filed in a binder by shipper and by product. Records will be kept for five years after testing. The records will be kept at each terminal office. Each time a confirmation test is performed, the results will be recorded. A separate log will be kept at each station. The results will be reviewed periodically to assure that quality control measures are adequate to protect product integrity and provide the desired product oversight. Information obtained by tank testing will be shared upon request, but only with participating shippers. Additionally, any shipper may sample any tank for analysis at any time. Action plans are in place to deal with upsets or other conditions which may occur from time to time that are out of the ordinary. These plans describe the actions that will be taken when such an event occurs. Actions In a barge compartment Pasco Operations will notify the terminal and shipper of the incident and assume the lead role to resolve the problem. In NWTC Tank - NWTC personnel will: Isolate the product and Stop Sales. Notify all affected parties of the problem. Work with responsible Party to: Correct the product or remove it from the facility. Determine the cause of the problem. Review plans to prevent future occurrences Responsible Party will be responsible for all costs associated with the incident. These costs may include, but not be limited to: Trucking Product Down-grading (redesignation) Tank Cleaning Testing Pipeline Down-time Tank Storage Barge Demurrage June 2013 Page 4 Quality Control Guidelines

PRODUCT QUALITY CONTROL Oversight Program for Sub-Octane Gasoline This oversight program will have an initial phase for sub-octane entering into the Tesoro Logistics Pipe Line system for the purpose of collecting baseline data on the octane values t for each shipper. After that period there will be an on- going PQ sampling and testing program for Pipeline and NWTC tankage to verify that sub-octane will meet the minimum posted octane requirement for ethanol blended gasoline. Batches Entering Tesoro Logistics Pipeline Beginning on June 19th, 2013 Tesoro Logistics Pipe Line has agreed to draw 3 samples from each shipper for each grade of Sub-Octane product entering the pipeline at the Salt Lake Pump Station. The following tests will be run on these samples: 1.) The octane value (R+M/2) will be determined using ASTM D-2500 on the as-is sample. 2.) The octane value (R+M/2) will be determined after blending with ethanol to a 9:1 gasoline to ethanol ratio, 10% ethanol by volume. If all testing shows that minimum posted octane is reached for the ethanol blended samples, sampling and testing of in-coming sub-octane product for each shipper will convert to quarterly verification testing. Northwest Terminalling Company Tankage Beginning June 19th, 2013 and continuing on a monthly basis thereafter, a one gallon tank sample will be drawn for each sub-octane grade at Pasco, Boise, and Pocatello and tested as follows: 1.) The octane value (R+M/2) will be determined using ASTM D-2500 on the as-is sample. 2.) The octane value (R+M/2) will be determined after blending with ethanol to a 9:1 gasoline to ethanol ratio, 10% ethanol by volume. All test results will be blinded and made available to Position Holders upon request June 2013 Page 5 Quality Control Guidelines

Tesoro NWTC Response Procedure Potential DRA Over Injection LGSTC notifies NWTC CSR that a refined product batch with a DRA concentration potentially higher than 15 ppm has been or may be delivered to a NWTC terminal. Discuss the potential need to temporarily discontinue DRA injection into the suspect product being delivered to the terminal Estimate DRA ppm in the suspect product batch and/or in the affected tank(s)* Yes Isolate suspect product to the extent possible and maintain rack operation with remaining tankage. Capture the following samples, as appropriate*: An all-level (composite) sample and various tank level samples (as appropriate) from the affected tank(s) A composite receipt sample from the pipeline (if available) The composite pipeline sample from LGSTC's Salt Lake Station (if appropriate) Retain additional samples for future testing Is the suspect product believed to exceed 15 ppm DRA?* Yes Can suspect product be isolated in the terminal? No CQMPC Document Ship appropriate* product samples via overnight courier to: CSPG: Elvira Spesikova 1000 So. Pine Ponca City, OK 74602 580-767-6278 Notify the CSPG at 580-767-6278 that: The sampled are in route, An expedited turnaround of the lab analysis is necessary, and They are to contact the NWTC CSR (and/or others if necessary*) with the lab results CSPG communicates lab results to the NWTC CSR No (and/or others as requested) Notify all affected customers of the potential over injection, including estimated DRA concentration levels and timing to receive lab analysis. Give each customer the option to lock out their rack liftings of the suspect product. Lock out rack liftings of the suspect product at customer's request (if any), pending customer notification and concurrence to continue lifting Yes Is suspect product believed to exceed 15 ppm DRA?* No Notify affected customers of lab results and give each of them the option to lock out their rack liftings of the suspect product. Yes Were customers notified of potential over injection? No Any customers elect to lock out the suspect product? Yes Work with subject customer(s) to develop and implement an action plan to get them unlocked on the suspect product* Release isolated product for rack lifting No Perform LI or NLI * With appropriate support and council from LGSTC Commodity Quality and Measurement Process Consultant (CQMPC) Perform NLI June 2013 Page 4 PROCESS TO EVALUATE FIELD TESTING RESULTS
