• This job is the black liquor evaporator and oxidation system. The purpose of this job is to evaporate water out of weak liquor to a targeting solid content. This is done by steam flow an liquor flow through a series of black liquor effects. It also creates condensate. I must maintain an adequate liquor solid, direct condensate to the proper location an balance our liquor inventory. I also assist the Control Room Operator in Powerhouse Operations (when needed).
• Also Operating the 3 Demenirizlation Plants. With these units we take Well water or Mill water an run them through a cation unit an a anion unit. These units take the organics out of the water to make boiler feed water for the boilers. I target an adequate caustic an water dilution for the anion regenerations and a acid to water dilution for the cation units.
• It is my job to oversee the feed water system in the department. The steam reducing stations 600-50 # and the 600-150#. Making sure that we keep right right pressure an temperature for each station.

• As control room operator/crew leader I oversaw all operations within the Power & Recovery Department.
Safety of the crew is my number one priority and making sure the crew understands my commitment to safety as a
leader is of the utmost importance to me.
•

• I am involved in safety training as well as job training for all employees in Power & Recovery.
• I ensure all operations are meeting or exceeding EPA demands for pollution.
• I maintain all steam headers at designated pressure ratings.
• Balance the steam load using several types of fuels based on efficiency needs.
• I balance all inventory to include steam, water, raw material supplies daily.
• I also monitor mill wide electrical distribution and main breakers.

• This job is a lime Kiln and Recausticizing area, I take diluted down chemicals, add other chemicals together to make the stronger base chemical for breaking down the wood chips to make pulp for the paper making process. also the lime kiln uses high temperature heat and a slow rolling kiln to make good quality lime to help with the reaction of the chemicals stronger.
• The chemicals I use here are NASH, sodium hydrosulfide, lime calcium hydroxide, caustic sodium hydroxide. when all this is mixed then it goes through several purifying tanks it becomes pure white liquor. this is a continuous process that must be done accurate and efficiently. Several tests, charting, DCS operations and calculations have to done continuously to make sure the quality is in the operating limits.

• This job is a chemical recovery boiler. My duties here are maintaining the recovery of black liquor in the process of burning it at a high temperature. Building liquor solids, keeping air flows, checking boilers for leaks. Steam is a biproduct of this boiler. It works in correspondence to the bark boiler in my past job classification.
• This job requires the operation of flow paths, liquor ignition, DCS operations and maintaining boilers operations. Logging data into DCS operations an following normal SOP an EOP operations.

• This job is a Boiler job. This is the Bark boiler, where we burn bark to build steam for the mill.
• My job duties are to oversee all equipment associated with burning bark. Such as natural gas guns, bark conveyors, bark feeders, ash collecting systems, and regulating air flow for EPA regulations.
• This is the main priority boiler for the mill. I constantly maintain everything so that the mill stays running properly. Monitor air flows, regulate bark consumption, and keeping everything nice and clean.
• DI (demineralization plant operator) here I maintain an operator the units to make clean purified water for the boilers. You have a cation, a anion unit that takes dirty water an makes purified water. Uses caustic an acid and resin to filter the water an takeout all the organics.

• I maintain all wastewater and sewage coming from the mill. We have huge classifiers where all the solid waste goes through and is transferred to a press that turns all the solid waste into tiny fibers which then are transported out of the mill.
• Also, I oversee water treatment. Chemicals are used to treat incoming water from the river to remove all unwanted solids and particles to make clean water. We have an 8-cell filter system that filters/cleans the water and a chemical inducing station that is used to keep water in a target range.
• Other on the job tasks include running a loader, bobcat, or forklift to assist in other areas as needed.

• Operate a crane on the production floor of the paper machine. Moving large reels of paper from the machine to the winder to be cut into smaller rolls and ultimately shipped out to customers.
• My job included operating the crane, taking paper samples, and clean up. When the paper went from the machine to the winder, I was responsible for verifying measurements and making the right size rolls for customers.

• My jobs duties here where to maintain roadways. From replacing sewer pipes, digging ditches, mowing, and performing minor vehicle and equipment maintenance.
• I operated excavators, back hoes, mowing tractors, mow trims, dump truck with snowplows, chippers, and bobcat. During the summer we done a lot of mowing and ditch digging. During these times I would either be running a tractor with a bush hog for mowing. Then for ditching I would either be operating a track hoe or backhoe.
• Wintertime consisted of mow trimming, ditching, tree removal and snow plowing. The mow trim was a tractor with a mowing boom that I got to operate. It cut limbs and cleaned up the roadway. Tree removal involved finding trees that were an would be a future to the roadway. We would cut them down and use the tractor hoe or backhoe with a grapple or thumb to pick these up and load into the dump trucks.
• The dump trucks were equipped with a snowplow and salt box. We would push snow and salt roads ways to get them clean for traffic. Also used a variety of hand cutting tools for jobs that had to be done. Tools such as, saws, torches, blowers, and chemical sprayers.
