Aboveground Storage Tank Requirements in South Dakota
A buyer's overview of SPCC, fire code, and permitting considerations for aboveground fuel tanks in South Dakota — before you specify a system.
Federal SPCC baseline
The federal SPCC rule (40 CFR Part 112) applies to non-transportation-related facilities storing oil aboveground above regulatory thresholds. As a general rule, a facility with more than 1,320 gallons of aggregate aboveground oil storage capacity — counting every container 55 gallons or larger — falls within SPCC's scope. Facilities that trigger SPCC must develop a written Spill Prevention, Control, and Countermeasure Plan, meet secondary containment requirements, and in many cases certify the plan through a licensed Professional Engineer.
Agricultural fuel storage carries specific SPCC exemption criteria that are common — and worth confirming early — in South Dakota given how much of the state's tank demand comes from farm and ranch operations.
South Dakota directly regulates ASTs by statute — unusual in your territory
Unlike several other states in your territory where standalone ASTs fall almost entirely to local fire code, South Dakota Codified Law Chapter 34A-2-100 specifically defines and regulates aboveground storage tank systems — a stationary tank or combination of tanks (including connected piping) storing petroleum or similar regulated substances — through the state's Storage Tank Section. That's a meaningfully different regulatory posture than Idaho or Wyoming, and worth explaining clearly to buyers who assume every state in the region treats ASTs the same way.
The statute carves out specific exemptions worth knowing: any farm or residential tank used for storing motor fuels for noncommercial purposes, tanks storing heating oil or motor fuels for consumptive use on-site, and produced-substance storage tanks directly tied to oil and gas production and gathering operations are excluded from AST regulation. Portable containers — tanks on wheels, trolleys, skids, pallets, or rollers, and vessels like 55-gallon drums — also fall outside the "stationary tank" definition the law regulates.
Local permitting can layer on top of state review
Some South Dakota municipalities add their own building-permit layer on top of state fire code review. As one representative example, Fort Pierre's municipal code requires a building permit application to be reviewed by the City Council or Board of Adjustments and Appeals, conditioned on the State Fire Marshal's approval of plans and fire code compliance, before the application goes to the South Dakota Division of Commercial Inspection and Regulation for final sign-off and permit issuance. Not every municipality runs an identical process, but it illustrates the layered structure worth checking for on any given South Dakota site: state fire code approval feeding into a local building permit decision.
Common mistakes we see in South Dakota projects
Assuming South Dakota's AST rules mirror a neighboring state's lighter-touch approach — SDCL 34A-2-100 gives South Dakota direct statutory AST regulation that Idaho and Wyoming don't have at the state level.
Assuming a farm tank is automatically exempt without confirming it actually meets the noncommercial-use exemption criteria in the statute.
Not checking whether the local municipality layers its own building-permit process on top of state fire code approval, which can add a review step buyers don't anticipate.
Typical permitting process
Confirm applicability — determine SPCC thresholds and whether SDCL 34A-2-100 exemptions apply to your facility.
Site & tank design review — siting, setbacks, secondary containment, and UL 142 double-wall construction.
Permit submission — state fire code review plus any local building-permit process the municipality requires.
Inspection & commissioning — final inspection, tank commissioning, and SPCC plan certification if applicable.
Requirements vary by facility type and municipality. Confirm current requirements with South Dakota's Storage Tank Section and your local building/fire authority.

FAQ
South Dakota AST FAQ
Are agricultural tanks exempt from SPCC in South Dakota?
Many farm fuel storage setups qualify for exemptions depending on use and capacity — confirm your facility's specific classification before assuming exemption.
Does South Dakota regulate ASTs differently than neighboring states?
Yes — South Dakota Codified Law Chapter 34A-2-100 directly defines and regulates aboveground storage tank systems by statute, a more direct state-level approach than states like Idaho or Wyoming take.
Which tanks are exempt under South Dakota's AST law?
Farm or residential tanks storing motor fuels for noncommercial use, tanks for consumptive on-site heating oil or motor fuel use, oil and gas production tanks, and portable containers like 55-gallon drums are excluded from the AST definition the statute regulates.
Will my municipality require its own building permit on top of state review?
Some do — check with your local building department, since some South Dakota municipalities layer local building-permit review on top of State Fire Marshal fire code approval.
