A kiln burner, a steam boiler, or a cavitating wort pump

The job is one of three machines

You are standing in an Oregon plant with a harvest, a brew day, or a dryer shift about to slip. The machine is a direct-fired hop kiln, a multi-pass steam boiler, or a wort pump that has started to cavitate. Those three failures do not share a fix. A burner that throws soot into aroma cones is not a water-treatment problem, and a pump that flashes at elevation is not a flame-safeguard problem.

USDA’s National Hop Report for 19 December 2025 puts Oregon at 5,354 harvested acres, 1,759 pounds per acre, and 9.418 million pounds, priced at $5.90 a pound^[1]. Washington harvested 31,198 acres that year and Idaho 5,102, so Oregon is the second state in a three-state report, not a footnote. The commercial crop is a Willamette Valley crop. That is why a kiln note exists for the valley and not for every town that happens to pour beer.

• Name the machine before you name the county. The form asks which job this is.
• A house, another state, and Salem, Eugene, Gresham, and Hillsboro stop the callback.
• Published dollars below are permit fees. They are not a price for the repair.

The rule depends on which flame is lit

Oregon DEQ states that any activity on Table 1 of OAR 340-216-8010 must obtain a permit^[2]. On the boiler permits, Basic Permit 04 covers natural-gas and propane boilers, with or without a small number 2 diesel backup, of 10 MMBtu per hour or more and less than 30, built after 9 June 1989. Backup means under 10,000 gallons a year and not the primary fuel. General Permit 11 covers oil-fired boilers over 10 MMBtu per hour and gas, propane, or butane at 30 MMBtu per hour or more, within an aggregate cap of 250^[2]. A hop kiln is fuel-burning equipment. It is not a steam boiler merely because it has a burner. Sending the kiln file to the vessel inspector, or the vessel file to the kiln mechanic, wastes the day you do not have.

When the machine is a boiler or pressure vessel, the Building Codes Division rule is different. An operating permit, or a temporary authorization, is required before a nonexempt vessel is placed in operation^[3]. Power boilers are inspected internally and externally at least every year. Low-pressure steam boilers are on a two-year minimum^[4]. If the inspector arrives and the vessel is not ready, the rescheduled visit is billed at the hourly rate in ORS 480.605^[3].

Who signs, and which dollars are actually printed

The equipment owner keeps the operating permit current and has to tell the division when the billing address changes. Fees not received within 90 days of the billing date may be doubled^[3]. ORS 480.595 sets the boiler installation fee at $175 and sets maximum annual operating fees at $110 for power boilers and $55 for other boilers, including the horsepower bands printed in the statute^[5]. Those operating figures are maxima, not a promise that every invoice matches them. Building Codes Division form 2502c adds a 12 percent surcharge and prints $196 for a boiler, $140 for a pressure vessel, and $56 for a beverage-service tank over five cubic feet^[6]. The form also states that unlicensed install, alter, or repair work can draw a civil penalty of up to $5,000 for each violation.

Where the next page stops being true

Bull Run water, Portland’s main supply, is reported at 7 to 11 ppm hardness, and the groundwater supply at about 80 ppm^[7]. That chemistry belongs on the Portland boiler note. It is false as a description of a Willamette kiln, which cares whether combustion products meet the cones, and false as a description of a Deschutes wort pump, which cares about barometric pressure. Hood River wholesale juice follows a pasteurization or other 5-log step under the state juice guide and 21 CFR 120, not a kettle boil. The coast page exists because a federal study measured higher steel loss nearer the ocean, including in shelter. Lane County files air permits with LRAPA; Marion County does not.

Checklist before you leave a number

1. Name the machine: kiln burner, steam boiler, or wort pump.
2. Confirm the plant is in Oregon and not in Salem, Eugene, Gresham, or Hillsboro.
3. Read the burner or boiler nameplate for heat input or horsepower and for pressure.
4. If it is a vessel, find the operating permit and the last internal inspection date.
5. If it is a kiln, note flame color and whether the drying air smells of soot.
6. If it is a wort pump above 3,000 feet, do not trust a sea-level NPSH margin.
7. Bring the water-treatment log only if a boiler is actually the machine.

The longer checks sit on the rule, and the worked lists sit on the kiln checks, the boiler-water checks, and the cavitation signs. Counties is the index of the notes that earned a path.
