Buying Land in Millard County, Utah

Millard County's defining feature for a land buyer is the Intermountain Power Project outside Delta -- a historically coal-fired plant now mid-transition to hydrogen-capable generation and one of the country's largest planned hydrogen storage hubs, built on a real, financed project rather than an announcement. This review is more limited than our other Utah county pages on zoning specifics; the gaps are stated directly.

Intermountain Power Project Energy Transition

Could not confirm

The Intermountain Power Project (IPP) near Delta is converting from coal to hydrogen-capable natural gas generation under the "IPP Renewed" project -- an 840-megawatt turbine designed to start on a 70% natural gas / 30% hydrogen blend with a stated goal of reaching 100% hydrogen by 2040, paired with the ACES Delta project using an underground salt dome for large-scale hydrogen storage. This is real, financed infrastructure (a reported $504 million federal loan guarantee, with the Los Angeles Department of Water and Power as a major power off-taker), not a speculative plan. Land near Delta and the plant site should be evaluated with this ongoing industrial buildout in mind -- ask the county and IPA directly about current construction activity, any related land acquisition, and infrastructure or noise impacts for a specific nearby parcel.

Countywide Zoning Ordinance

Could not confirm

Millard County has an adopted Zoning Ordinance (Title 10) and Subdivision Regulations (Title 11) administered by the Planning and Zoning Department, with offices in both Fillmore and Delta. This review could not verify the specific zoning-district names or minimum lot sizes from public search results before search capacity was exhausted -- confirm district and permitted uses directly with the department for any specific parcel rather than assuming a lot-size standard.

Research Completeness for This County

Could not confirm

This page's research is less complete than our other Utah county pages in this batch: current population and growth figures, specific zoning-district lot sizes, and assessor/recorder/GIS office contact details could not be independently verified before this review's search capacity was exhausted. Those gaps are stated explicitly in the sections and contacts below rather than filled with unverified assumptions -- treat this page as a starting point and confirm directly with the county for anything not sourced here.

The Intermountain Power Project: a real, financed shift from coal to hydrogen

Delta is also the site of a separate, large utility-scale solar and data-center buildout (the Creekstone Energy / Delta Gigasite project), covered on our dedicated solar and wind leasing page for the county. The Intermountain Power Project, on the outskirts of Delta, has long been one of the larger coal-fired power plants in the western United States, supplying power historically to California utilities including the Los Angeles Department of Water and Power (LADWP). It is now in the middle of a genuinely significant, well-documented transition under the "IPP Renewed" project: coal-fired generation is being phased out in favor of a new 840-megawatt turbine designed to run initially on a blend of roughly 70% natural gas and 30% hydrogen, with a stated long-term plan to convert to 100% hydrogen by 2040. This isn't a speculative or early-stage announcement -- reporting describes a reported $504 million federal loan guarantee tied to the project, and construction and commissioning activity has been underway.

Layered on top of the generation transition is the ACES Delta project, which takes advantage of a large natural underground salt dome beneath the plant site to store hydrogen in engineered salt caverns -- described as one of the largest planned hydrogen storage hubs in the United States, intended to convert excess renewable electricity into hydrogen for later use in power generation. For a land buyer, the practical relevance is that this represents an active, large-scale industrial energy project immediately adjacent to Delta with an extended buildout timeline (through at least 2040) -- if you're evaluating land near the plant site or along associated infrastructure corridors, ask Millard County and the Intermountain Power Agency directly about current construction activity, any planned expansions, and whether a specific parcel is near any right-of-way, easement, or land-acquisition activity tied to the project.

Zoning and everything else: what this review could verify, and what it couldn't

Millard County does administer an adopted Zoning Ordinance (Title 10 of the county code) and separate Subdivision Regulations (Title 11), through a Planning and Zoning Department with offices in both Fillmore (the county seat) and Delta, overseen by a seven-member Planning Commission drawn from across the county. That much is confirmed. What this review could not verify from public search results -- and states here explicitly rather than guessing -- is the specific structure of Millard County's zoning districts (agricultural, residential, or otherwise) and their minimum lot sizes, current county population and growth trends, and direct contact details for the county's Assessor, Recorder, and any GIS office.

This gap exists because this review's research capacity (web search access) was exhausted while researching this, the last of seven Utah counties covered in this batch, before those specific details could be confirmed. Rather than fill them with template assumptions or figures borrowed from other rural Utah counties, they're flagged here as open items: before making an offer on land in Millard County, get the specific zoning district, minimum lot size, and permitted uses in writing from the Planning and Zoning Department, and get current parcel, assessment, and title information directly from the Assessor's and Recorder's offices.

What we could and couldn't confirm

This Millard County page is explicitly less complete than the other six Utah county pages produced alongside it: this review's web-search capacity was exhausted before specific zoning-district lot sizes, current population/growth figures, and Assessor/Recorder/GIS contact details could be independently verified, and no attempt was made to fill those gaps with assumptions, templated figures, or numbers borrowed from comparable Utah counties. IPP Renewed and ACES Delta figures are drawn from multiple independent, corroborating industry and news sources current as of their publication dates; confirm current project status and timeline directly with the Intermountain Power Agency, since large energy-infrastructure timelines can shift.

Verify directly with: Millard County's Planning and Zoning Department for zoning (a gap this review could not fully close), the Intermountain Power Agency for current IPP Renewed/ACES Delta project status, and Central Utah Public Health for septic

Who to Call Before Buying Land in Millard County

This review is incomplete for Millard County relative to the other six Utah counties covered alongside it: it could not verify direct contact details for a Millard County Assessor, Recorder, or GIS office, or a direct phone line for Central Utah Public Health's environmental health division, before search capacity was exhausted. Septic permitting runs through the multi-county Central Utah Public Health district (confirmed via Millard County's own county code, section 5-1-1, which establishes the district's jurisdiction), not a dedicated Millard County department. Use the Millard County government website's general contact page, or call the Planning and Zoning number above and ask to be directed, to reach the Assessor's or Recorder's office directly.
