June 3 and 4, 2014 Class II Wastewater Inspection, unannounced

September**26f~)**

## J.MarkDir~ OnJune 3 and 4, 2014 I conducted a water quality sampling inspection ofthe Tesoro refinery atAnacortes. I arrived at the facility at approximately 12:30 onJune 3 and met withNeilNorcross. This was anunannounced inspection andwe set the agenda for it. On June 3, I inspected the wastewater treatment system. OnJune 4, I collected samples and reviewed the laboratory procedures. 

### Description ofFacility: Process wateris treated inprimary and secondary systems consisting ofanAPI oil/water separator, neutralization pit, primary clarifiers, bioreactor, secondary clarifiers, and settlingponds. They also have a pondto collect stormwater andhavethe capability of skimming oil from thetop. The storm water can be sent through treatment, ifneeded.


### Jnne 3, 2014
Site Inspection: We checked in withthe wastewatertreatment operator. Operators work 12-hour shifts, pulling samples everytwohours to checkhowwell treatment is going. They canrespond quicklywhen something does not look good.
We walked through the treatmentplantsequentially, starting withthe APis. The two APis are covered to containbenzene vapors. Skimmers collectthe oil offthe top while a rake automatically collects sludge. API sludge is discharged to a covered thickener unit. The air emissions from these units are scrubbed with a water scrubberthen discharged to a carbon scrubber. Water is used as a seal onthe API covers.

### Tesoro Class 2 Inspection Report Page2 of4

Atthe end ofthe APis is theneutralizationpit. Sanitary wastewateris collected from the refinery and treated in a septictank. The effluentfrom the septic tankis discharged into the neutralizationpitwhere spentprocess acid is added. ThepH ofthe spent acid ranges from 2 to 4. The spent acid is added once ortwice a day 

### ina batchprocess which keeps the neutralization pit at a lowenoughpHto effectivelykill the microorganisms inthe septictank effluent. A local septic haulerperiodicallypumps septic tank solids, which are then treated at a local publicly ownedtreatment facility.
The contents ofthe neutralization pitare continuouslypumpedto thehead ofthe industrial wastewater treatment system where they neutralize theprocess wastewater influent, whichranges from pH 10 -12. The neutralizionpit effluentis added to the end ofthe API separators (the after bay). The pH ofthe wastewateris monitored downstream ofthe neutralization pitaddition inthe after bay ofthe API separator.
Thenext units inthetreatment system are two primary clarifiers. Theseunits have aluminum covers with a water seal. Theydischarge solids into a sludgereservoir. The solids from the reservoir are discharged to the thickenerunit. The air emissions from the primary clarifiers are scrubbed with a carbon and water scrubber. Thecapacity ofthe thickener unit is approximately 1500 barrels. Sludgefrom the sludgethickenerunitisperiodically withdrawn, dewatered and sent offsite as hazardous waste. Ifsupernatant is generated from the dewatering process, itis discharged to the beginning ofthe wastewater treatmentprocess. The thickener sludge (API sludge) is regulated bydangerous waste rules.
Activated sludgebasins comprisethe secondarytreatment system. Thebasins are operated in series. Since a buildup offoam sometimes flows over the side and onto the ground, Tesoro has installed a foam gate/corral to keep itwithin the basins. The basins have DO probes, which automatically adjust the blowers to provide adequate aeration.
Aerationbasin effluent is discharged into two secondaryclarifiers. The incomingtreated wastewater looked clean.
The wastewater is pumped from the secondary clarifiers into the west pond for settling and then into the eastpond when the pumpout lowers its level. The final effluentfrom the holdingponds is pumpedthrough an outfall line atthe refinery's dock. The effluentis pumped out inbatches. Thelength oftime Tesoro pumps depends uponthe level ofthe ponds. During wet weather, effluent is pumped over a longerperiod inorder to discharge the extra volume ofstorm water. The two ponds are cleaned about every four years. This is done by chartingthe depths inthe ponds andthen vacuuming the areas with a lot ofbuild up ofsilt.
A diversiontank isusedto store diverted off-spec final effluent ordiversions from units down for maintenance. The stored wastewater canthenbe slowly bled into the wastewater systemfor additional treatment in orderto meetpermit limits.

A beltfilter press with polymer addition thickens secondary sludge. The solids are approximately 10% after processing. The sludge is land applied to the biosludge landfann facilities (bugfarms). The Skagit County Health Departmentregulates the biosludge landfannfacility.
We checked back into the control room ofthe wastewatertreatmentplant. They have manuals for the wastewater treatment system equipment available in the control room for easyreference. To makethe transition easierbetween shifts, a bound log is maintained for operator comments onthe system. This allows tracking oftrends and problems.
I departed the facility at approximately 14:15.

### 4, 2014

I checked inwith the guard at approximately 11:05 and received a badge to pass onto refineryproperty.
Tesoro is accredited for the following parameters: ammonia, BOD, COD, Total residual chlorine, dissolved oxygen, hexane extractable O&G, pH, total phenolics, TSS, sulfide, and fecal coliform.
Rawdata for NPDES parameters are entered into a logbook. The lab has two logbooks for NPDES parameters. One logbook is inthe biological area and covers BOD and fecal coliform testing. The other logbook is inthe chemical testing area. The logbooks are bound and a stamp has been specifically designed with the necessary information for eachparameter. Thepages are stamped for each parameter and the required information is directly filled into the logbook. The lab results are entered into the computer system, WINBLISS, to provide information to the operators and environmental personnel. They periodically check the logbooks to ensure completeness and quality work. The logbooks are filled incompletely with ink. Control charting is done, butno duplicates are run. Tesoro employs a good chain ofcustody. The samples are tagged when collected with pH, flow temperature, pumpingtime and the amountpumped all logged onto the tag and signed by the collector.
Tesoro discharges its wastewater bythe batch during late morning and early afternoon. A grab sample is collected early in the morning and analyzed. Ifthere is a problem, treated wastewater is notpumpedto the bay. Discharge pumping takes place after the test results have been examined for that batch ofprocess water. Required composite and grab samples are taken during the discharge.

### Tesoro Class 2 Inspection Report Page4 of 4

I split a Tesoro's composite sample. The tag displayed the temperature and pH instrumentreadings atthe time ofthe pickup. Weproceeded to Tesoro's outfall where I collected grab samples ofeffluent. Tesoro has a smallpump thatruns continuouslypulling water from the final holding pond and allowing itto runback into the pond.
I collected grab samples at 11:45. Tesoro chose notto split grab samples.
I conducted an exit interviewbut had not observed anything during the inspectionthat needed to be addressed. Sampling Results: The attached table shows theresults ofthe samples analyzed byEcology and Tesoro. Samples were analyzed for all ofthe parameters in theNPDES permit and priority pollutant metals. Allpermitparameters met limits.
Metals data are comparable with previously reported data.
Conclusions: 

### With Tesoro's chronic dilution factor, all priority pollutant metalresults are below water quality criteria.
The wastewater treatment system appeared to be functioning properly and Tesoro was in compliance withtheir NPDES permit on the day ofthe inspection.
