Two plants Woods Cross
One name, two companies, and a city line nobody can see from the road
Silver Eagle, and the refinery that borrowed the name.
The plant everyone calls the Woods Cross Refinery has both of its published addresses in West Bountiful, confirmed at the U.S. Census Bureau geocoder on 15 August 2026. The refinery genuinely inside Woods Cross is Silver Eagle at 2355 South 1100 West, built in 1954, running Uinta Basin yellow wax crude exclusively, and investigated twice by federal safety authorities in 2009. Two companies, two addresses, two cities, and one name doing the work of both.
My own ground is Southern Utah, four hours south of here, so these pages are researched rather than lived. Every figure on them was read at the body that issues it: the city code and the city budget notices, the Census boundary files, the state transit, wildlife and environment agencies, the county clerk, and the federal aviation and chemical safety records. Each one carries the date it was checked. A Davis County partner agent handles the work on the ground.
The live question
Is the Woods Cross refinery actually in Woods Cross?
No. The plant everybody means when they say the Woods Cross refinery is the HF Sinclair Woods Cross Refinery, a 45,000 barrel a day operation, and both of its published addresses, 1070 West 500 South and 393 South 800 West, returned West Bountiful city from the U.S. Census Bureau geocoder on 15 August 2026. It sits about 1.1 miles north northwest of Woods Cross City Hall with the city line in between. That plant is West Bountiful's subject and this page names it, locates it and leaves its operations, its capacity history and its regulatory record alone.
The refinery that is genuinely inside Woods Cross is Silver Eagle Refining, at 2355 South 1100 West, about a mile south southwest of City Hall, and the same geocoder returned Woods Cross city for it. It is a much smaller plant and a far more interesting one, because it exists to do something almost no other refinery does: it processes yellow wax crude exclusively, a waxy Uinta Basin product that most refineries cannot run.
Why the names got crossed is straightforward and worth saying once. The 84087 postal code covers Woods Cross and West Bountiful together, the rail stop that named this city was here first, and both plants sit on the same industrial corridor that runs either side of a boundary nobody can see from the road. This is the third time on this companion that a Woods Cross name has landed on something partly or wholly somewhere else, and it is not the last.

Silver Eagle
A small plant built for a waxy Utah crude that most refineries cannot process.
The plant at 2355 South 1100 West was originally built in 1954. Silver Eagle Refining purchased it in January 2000, and in June 2011 the Silver Eagle group was acquired by The International Group. What it runs is the unusual part: the company describes the facility as processing yellow wax crude exclusively, a crude with high wax content, very low sulfur content and very low acid content. That is a Uinta Basin product, and a plant built specifically to handle it is a piece of Utah industrial geography rather than a generic refinery that happens to be nearby.
Three primary units do the work: an atmospheric crude distillation unit, a vacuum distillation unit, and a Mobil Distillate De-waxing unit. The atmospheric unit yields heavy naphtha, diesel, atmospheric gas oil and atmospheric tower bottoms; the diesel is sold as ultra low sulfur diesel, and the heavy naphtha is shipped to the company's facility at Evanston, Wyoming. Vacuum gas oils and refined blendstocks come off the rest of it.
On size, this page prints a historical figure and no current one, because the company publishes no current capacity. The 2009 federal investigation described the plant as a 10,250 barrel a day refinery, which is roughly a quarter of the throughput of the larger plant up the road in West Bountiful. Anyone quoting a present tense barrels per day number for Silver Eagle is quoting a figure the company does not publish.
The plant is a working industrial facility with no public access, so the fact block below is a drive by orientation. There is nothing to visit and nothing to tour, and the reason it is on this companion at all is that the practical city guide names the wrong refinery as the city's signature employer and never names this one except in an incident clause.
The details
Getting there
From City Hall take 1500 South west across the tracks to 1100 West and turn south. The corridor runs north to south on the west side of the rail alignment, with the Silver Eagle plant at the south end of it and the West Bountiful plant about two miles north, and the city boundary between them is invisible from the road. There is no visitor parking and no public entrance at either plant.
Before you go
- Do not run the two companies' records together. Two different operators, two different addresses, two different cities.
- The 10,250 barrel a day figure is from the 2009 federal investigation. It is not a current capacity and should not be printed as one.
- Air quality is a regional regulatory subject rather than a street level one. Check the designations at the state, not at an aggregator.
- If a parcel matters to you, drive it at different hours and in different wind. That is worth more than any published description.
2009
Two incidents in one year, and a federal investigation that named corrosion.
Silver Eagle had two separate incidents in 2009 and both were investigated by the U.S. Chemical Safety Board, which is the federal body of record for exactly this kind of event. In January 2009 a flash fire and explosion at the plant sent four workers to hospital with burns and led to nearby homes being evacuated. Then on 4 November 2009, shortly after nine in the morning, a ten inch pipe carrying pressurized hydrogen failed catastrophically. The blast damaged homes in Woods Cross and North Salt Lake, and at least one house was reported moved off its foundation. The board publishes the case.
The cause finding reported when the final report issued in 2014 was severe pipeline corrosion. That relay is worth flagging as a relay: the wording here comes through contemporaneous news coverage of the report rather than from the report text itself, so anyone quoting the finding formally should read it at the board rather than here.
That November 2009 event is the accident the city's own planning record refers to, seventeen years later, when it explains why residential potential near the FrontRunner station has been treated as very limited. It is unusual for a municipal document to be that direct about its own land, and it is the reason this page and the station page have to be read together rather than separately.
None of that is a claim about the plant today, about its current operations or about its compliance posture. It is a documented history with a federal investigating body attached, printed with dates, and that is the whole of what this page asserts about it.
What belongs to the other plant, and is not on this page
The 2012 process release that deposited oil on nearby homes and yards, and the federal Clean Air Act settlements that get mentioned in the same breath, are events at the larger plant in West Bountiful under its own operators. They are not Silver Eagle events, they did not happen at 2355 South 1100 West, and they are not narrated here. When that city's companion is built it will carry them, with its own dates and its own sources. The reason to draw the line this sharply is that the practical Woods Cross city guide currently chains all of it into one sentence, which reads as a single facility's record and is wrong about two companies at once.
Two plants
Side by side, with the city line put where the Census Bureau puts it.
This is the table that settles the confusion, and every geographic cell in it was produced by running the published address through the U.S. Census Bureau geocoder rather than by reading a mailing address. The Census Bureau is the issuing body for incorporated place boundaries, which is what makes this better than a parcel viewer screenshot.
| Silver Eagle Refining | HF Sinclair Woods Cross Refinery | |
|---|---|---|
| Address | 2355 South 1100 West | 1070 West 500 South, with a second published address at 393 South 800 West |
| City, per the Census Bureau geocoder | Woods Cross city, confirmed 15 August 2026 | West Bountiful city, confirmed 15 August 2026 on both addresses |
| From Woods Cross City Hall | About 1.0 mile south southwest, roughly three minutes | About 1.1 miles north northwest, roughly four minutes, across a city line |
| Size | Described as a 10,250 barrel a day refinery at the time of the 2009 federal investigation; no current figure is published | 45,000 barrels a day, per the operator |
| What it runs | Yellow wax crude exclusively, a high wax, very low sulfur, very low acid Uinta Basin crude | Not described here. It is the other city's plant and the other city's page |
| On this site | This page | Named and located here; its history belongs to the West Bountiful companion when that is built |
Addresses as published by the operators and by the U.S. Environmental Protection Agency facility record; municipal geography from the U.S. Census Bureau geocoder, benchmark Public_AR_Current, vintage Current_Current, run on 15 August 2026. Distances and drive times from City Hall are estimates. The shared 84087 postal code is the mechanical reason the mailing addresses do not track the city limits.
The 84087 postal code is not a city boundary, and on this corridor the difference is about two miles and one municipal line. A postal code, a mailing address, a business name and a city boundary are four different things, and on this stretch of south Davis all four disagree. The plant that carries the Woods Cross name is in West Bountiful. The plant inside Woods Cross carries a company name most people here would not recognize. The pond at the west end of 1600 North has its state published address in West Bountiful and its parking lot in Woods Cross. The airport named for Bountiful is inside Woods Cross. If a document, a listing or a review matters to you, check the address against the Census Bureau geocoder or the county parcel record rather than trusting the name on it. It takes a minute and it is the single most useful habit anyone can bring to this corridor.
Living with it
Air quality here is a regional record and the homework is a parcel level exercise.
The published position, restated so nothing on this companion contradicts the practical city guide, is this. The Salt Lake City fine particulate nonattainment area, which includes Davis County, was redesignated to attainment with a maintenance plan for the twenty four hour standard in late 2025. The Northern Wasatch Front remains classified as serious nonattainment for ozone, which is a summer problem rather than a winter one. The state issues action day guidance in both seasons. Both designations move, so re-verify them at the Utah Division of Air Quality before relying on either, and note that the south Davis basin also sits under the Wasatch Front's wintertime inversions independently of anything on this corridor.
That is the whole of what this page will say about air, because the compliant and the useful version of this subject are the same version: describe the corridor, cite the published record, and hand the reader the homework. This page will not tell you that a given street has bad air, and it will not characterize anyone who lives on one. Salt Lake County's companion carries the inversion itself as its own subject, and the valley in winter page is where that is written rather than here.
The homework, then. Measure the actual distance from a parcel to the corridor rather than guessing from a map, because a mile is a great deal more than it looks like at this scale. Learn which way the prevailing wind runs on the day you are standing there and ask a neighbor what it does in January. Drive the specific parcel at more than one hour and in more than one season. And check the city, not the postal code, because on this corridor a block can change municipality and the tax notice, the police department and the park rules change with it.
The last piece is planning rather than air. The city has already written down, in an adopted general plan element, what the presence of the larger plant has meant for what can be built near the station. That is the single most useful document a buyer can read about west side Woods Cross, and the station page carries it in full.

The corridor, answered.
No. The HF Sinclair Woods Cross Refinery, a 45,000 barrel a day plant, publishes addresses at 1070 West 500 South and at 393 South 800 West, and both returned West Bountiful city from the U.S. Census Bureau geocoder on 15 August 2026. It sits about 1.1 miles north northwest of Woods Cross City Hall with the municipal line in between. The refinery that is genuinely inside Woods Cross is Silver Eagle Refining at 2355 South 1100 West, a much smaller plant, about a mile south southwest of City Hall.
The refinery inside the Woods Cross city limits, at 2355 South 1100 West. The plant was originally built in 1954, Silver Eagle Refining purchased it in January 2000, and the Silver Eagle group was acquired by The International Group in June 2011. It runs three primary units, an atmospheric crude distillation unit, a vacuum distillation unit and a Mobil Distillate De-waxing unit, and produces ultra low sulfur diesel, heavy naphtha shipped to the company's Evanston, Wyoming facility, atmospheric gas oil, tower bottoms and vacuum gas oils.
A waxy crude oil from Utah's Uinta Basin, described by the operator as having high wax content, very low sulfur content and very low acid content. It is difficult enough to handle that most refineries cannot run it, which is the interesting part of the Silver Eagle story: the small plant inside Woods Cross exists in large part to process a Utah crude that needs specialized equipment, and the de-waxing unit on site is exactly that specialization.
Two separate incidents, both investigated by the U.S. Chemical Safety Board. In January 2009 a flash fire and explosion sent four workers to hospital with burns and nearby homes were evacuated. On 4 November 2009, shortly after nine in the morning, a ten inch pipe carrying pressurized hydrogen failed catastrophically; the blast damaged homes in Woods Cross and North Salt Lake and at least one house was reported moved off its foundation. The cause finding reported when the final report issued in 2014 was severe pipeline corrosion, and that wording comes through news coverage rather than from the report text.
There is no current published figure, so this page prints only the historical one. The 2009 federal investigation described the plant as a 10,250 barrel a day refinery, which is roughly a quarter of the throughput of the larger plant a couple of miles north in West Bountiful. The company does not publish a present day capacity, so any source quoting a current barrels per day number for Silver Eagle is quoting something the operator has not stated.
The plant was purchased by Silver Eagle Refining in January 2000, and in June 2011 the Silver Eagle group was acquired by The International Group. The operator's own site is the issuing body for its ownership and its process description, both checked 15 August 2026. Operating status, ownership and what a plant runs all change, so a page relying on any of it should be re-checked at the company and at the state air quality permits annually.
Because of the rail stop and the shared postal code rather than because of the city limits. The 84087 postal code covers Woods Cross and West Bountiful together, the Woods Cross name has been attached to this stretch of the county since the railroad crossing of 1869, and the plant's mailing address carries the postal name. The Census Bureau geocoder puts both of its published addresses in West Bountiful city. This is the same pattern that puts an airport named for Bountiful inside Woods Cross and a pond addressed in one city with its parking lot in the other.
It is a regional regulatory question with a published answer rather than a street level one. The Salt Lake City fine particulate nonattainment area, which includes Davis County, was redesignated to attainment with a maintenance plan for the twenty four hour standard in late 2025, while the Northern Wasatch Front remains classified as serious nonattainment for ozone, which is a summer problem. The state issues action day guidance in both seasons, and the whole south Davis basin sits under the Wasatch Front's wintertime inversions. Re-verify both designations at the Utah Division of Air Quality, because they move.
Four things, and none of them is a description someone else has written. Measure the actual distance from the parcel to the corridor rather than estimating it from a map. Find out which way the prevailing wind runs and ask what it does in January. Drive the specific parcel at more than one hour and in more than one season. And check which city the parcel is in against the Census Bureau geocoder or the county parcel record rather than trusting the postal address, because on this corridor a block can change municipality and the tax notice, the police department and the park rules change with it.
A name on two plants, and a boundary worth checking before you sign anything.
The most useful habit anyone can bring to south Davis is checking the address rather than the name on it. Postal codes, business names, mailing addresses and city limits disagree along this corridor, and the differences decide which city taxes a parcel, which police department answers, which park rules apply and which planning document governs the ground behind it. That is parcel level work rather than city level work. Tell me what you are weighing and I will put you with a Davis County partner agent who checks these lines for a living, and stay on the file for the financing side.
