API 653 Tank Inspection Support in Kansas

Short answer: In Kansas, an API 653 tank inspection is evaluated and signed by the owner's API 653 Authorized Inspector. The Kansas Department of Health and Environment registers and permits many aboveground tanks, but it exempts refinery tanks, pipeline terminals and oil-production tanks, so the API 653 obligation at those sites comes from EPA's SPCC rule, PHMSA's breakout-tank rule, OSHA PSM and owner standards. Atlantis performs the NDE behind the inspection and delivers the data to your inspector in a digital report.

Kansas sits in the middle of the country's crude and natural-gas-liquids network. Three refineries, at Coffeyville, El Dorado and McPherson, process Mid-Continent crude. Crude gathering systems collect oil from thousands of tank batteries in central and western Kansas and move it toward the refineries and toward the storage hub at Cushing just across the Oklahoma line. The Conway and Hutchinson area is one of the country's main hubs for natural gas liquids. Ethanol plants, fertilizer plants, aircraft factories in Wichita, military bases and grain-belt fuel distributors add their own tanks. Prairie weather, from summer heat to hard freezes, hail and high winds, works on all of them. This page explains where those tanks are, what API 653 requires, how KDHE's rules and federal rules fit together, and what Atlantis does. Atlantis performs the NDE; your API 653 Authorized Inspector remains inspector of record and signs the inspection report. To start, send us your Kansas tank list.

Where API 653 tanks are in Kansas

Direct answer: Kansas's field-erected steel tanks are concentrated at the Coffeyville, El Dorado and McPherson refineries, at crude and product pipeline terminals and breakout stations, at the Conway and Hutchinson NGL complex, at ethanol and fertilizer plants, at Wichita's aviation and McConnell Air Force Base fuel farms, at Kansas City-area terminals, and at fuel distributors across the state.

The three refineries

CVR Energy's refinery at Coffeyville in southeast Kansas, HF Sinclair's refinery at El Dorado northeast of Wichita, and the CHS refinery at McPherson in central Kansas together hold the state's largest concentrations of crude, intermediate and product tankage. Each sits at the end of crude gathering systems and at the start of product pipelines, so their tank farms combine refinery storage with pipeline receipt and delivery tanks. Floating-roof crude tanks, cone-roof product tanks and heated asphalt and residual tanks are all present, and most have decades of inspection history to build on.

Crude gathering, pipelines and breakout tanks

Central and western Kansas produce oil from many small leases, each with its own tank battery. Those production tanks are normally built to API 12-series specifications and managed under API RP 12R1, not API 653. Once the crude enters a gathering or transmission system, it passes through station tanks and breakout tanks that are field-erected and fall under API 653. Major crude and product pipelines cross Kansas toward Cushing, the Gulf Coast and the upper Midwest, and their pump stations and terminals hold tanks that PHMSA regulates as breakout tanks.

Conway, Hutchinson and the NGL hub

McPherson and Reno counties host one of the country's largest concentrations of natural gas liquids storage and fractionation, using salt caverns deep underground. Cavern storage and pressurised bullets and spheres are not API 653 equipment, but the same complexes include atmospheric tanks for brine, condensate, fuels and treating chemicals that are. Separating the atmospheric tanks from the pressurised storage is the first step in scoping any NGL site.

Ethanol, fertilizer and agriculture

Kansas has dozens of ethanol plants, mostly in the western and central grain belt, each storing denatured ethanol, denaturant and process liquids in field-erected or large shop-built tanks. CVR Partners operates a nitrogen fertilizer plant at Coffeyville and Koch operates one at Dodge City, and liquid nitrogen-solution fertilizer is stored in large carbon-steel tanks at plants and at agricultural retailers across the state. Nitrogen solutions can be corrosive to carbon steel and are often managed by owners on API 653 principles even when no rule requires it.

Wichita, military bases and Kansas City

Wichita calls itself the Air Capital of the World, and its aircraft plants, airports and McConnell Air Force Base, home to a tanker wing, hold large jet fuel inventories. Fort Riley and Fort Leavenworth maintain their own fuel storage. In the Kansas City metropolitan area, which straddles the Kansas-Missouri line, product terminals on both sides of the river supply fuel to the region; see our tank inspection services in Kansas City page for the metro. Power stations, including Wolf Creek near Burlington and the coal and gas plants across the state, store fuel oil and water-treatment chemicals.

What API 653 requires, in plain terms

Direct answer: API 653 governs inspection, repair, alteration and reconstruction of in-service atmospheric steel tanks built to API 650 or API 12C. It requires monthly owner checks, an Authorized Inspector's external inspection at least every five years, shell UT surveys and an out-of-service internal inspection on intervals tied to measured corrosion. The current Fifth Edition carries addenda through Addendum 4 (July 2025).

Routine in-service checks. Owner personnel inspect each tank at least monthly for leaks, shell distortion, settlement, coating and roof damage, and foundation problems. On the prairie that includes hail damage to coatings and roofs, wind damage to appurtenances and ice on floating roofs and stairways.

Formal external inspection. The Authorized Inspector carries out an external inspection at least every five years, or sooner when shell corrosion is rapid, because the code links the interval to a quarter of the remaining shell corrosion life.

Shell UT thickness. Where UT readings are used, they are required within five years while the corrosion rate is unknown, then at the lesser of half the remaining shell corrosion life or fifteen years.

Internal inspection. A new tank's first internal inspection is due within ten years, extendable by credited safeguards up to twenty years without a release prevention barrier or thirty with one. Later intervals are calculated from measured bottom corrosion within the same ceilings, or set by a qualifying risk-based assessment by the owner's specialists; breakout tanks regulated by PHMSA cannot use that risk-based option for the internal interval.

Brittle fracture, settlement and repairs. Kansas winters can bring metal temperatures well below freezing, so API 653's brittle-fracture screening matters for older tanks, repairs and changes of service. The code's settlement annex and repair and hydrostatic-test rules complete the picture. Addendum 4 revised the text on measuring tank-bottom plate thickness, so check procedures against the current edition from api.org. See API 653 tank inspection intervals explained and the API 653 tank inspection guide.

Kansas regulations that sit on top of API 653

Direct answer: KDHE requires registration and an annual operating permit for nonexempt aboveground tanks storing fuels, flammable or combustible liquids, listed hazardous substances and used oil, with State Fire Marshal approval for new flammable-liquid tanks. Refinery tanks, pipeline terminals, DOT-regulated pipeline facilities and oil-production tanks are exempt from KDHE's AST rules, so API 653 at those sites rests on SPCC, PHMSA and PSM. Confirm current requirements with KDHE.

KDHE Storage Tank Section: registration and permits

Under the Kansas Storage Tank Act and K.A.R. 28-44, the Storage Tank Section of the Kansas Department of Health and Environment requires owners to register nonexempt ASTs and display a valid operating permit before product can be placed in them. The programme covers tanks storing liquid petroleum fuels (including gasoline, diesel, fuel oil, kerosene, aviation fuels, ethanol and biodiesel blends), flammable or combustible liquids, liquid hazardous substances listed in 40 CFR 302.4 that are not RCRA hazardous waste, and used oil. Permits run from August through July and are renewed each year through KDHE's online system, and changes of ownership, status or product must be reported. For new or replacement tanks holding flammable or combustible liquids, the Kansas State Fire Marshal's Office must approve the installation before construction starts. Exemptions include small business tanks under 660 gallons, farm and residential motor-fuel tanks of 1,100 gallons or less, tanks associated with oil and gas production, ASTs at petroleum refining facilities, pipeline terminals, pipeline facilities regulated by the US Department of Transportation, flow-through process tanks and tanks holding agricultural materials regulated by the Kansas Department of Agriculture. The programme's emphasis is registration, permitting, fire-code approval and release response; it is not a substitute for an integrity-inspection standard, so check with KDHE what applies to your tanks.

EPA SPCC through EPA Region 7

EPA's Spill Prevention, Control and Countermeasure rule, 40 CFR Part 112, enforced in Kansas by EPA Region 7, is where most Kansas tank owners find their integrity-testing obligation. Bulk storage containers must be tested or inspected for integrity on a regular schedule and after material repairs, following industry standards: API 653 for field-erected tanks and STI SP001 for shop-built tanks. That applies to refinery and terminal tanks that KDHE exempts, and to ethanol plants and distributors that KDHE also permits.

PHMSA directly regulates hazardous-liquid lines

Under 49 CFR 195.432, steel aboveground breakout tanks on regulated hazardous-liquid pipelines operating at atmospheric or low pressure must be inspected in accordance with API 653, excluding the code's alternative risk-based internal interval; pressurised breakout tanks follow API 510. Kansas has never taken on intrastate hazardous-liquid pipeline authority, so PHMSA's Office of Pipeline Safety inspects both interstate and intrastate liquid lines and their breakout tanks in Kansas. The Pipeline Safety Section of the Kansas Corporation Commission inspects intrastate natural gas pipelines under PHMSA certification, and the KCC's Conservation Division oversees oil and gas production operations.

OSHA PSM and agricultural storage

Kansas has no OSHA State Plan for private employers, so federal OSHA enforces 29 CFR 1910.119 at the refineries, NGL facilities and covered chemical and fertilizer processes, where mechanical integrity requires inspection following recognised and generally accepted good engineering practices, typically API 653 for atmospheric tanks. Storage of fertilizers and other agricultural materials is regulated by the Kansas Department of Agriculture rather than KDHE; confirm its current requirements for nitrogen-solution and other bulk liquid fertilizer tanks.

Radiography in Kansas

Kansas is an NRC Agreement State, and industrial radiography licences are administered by KDHE's Radiation Control Program. Repair-weld radiography is carried out only by crews properly licensed for work in Kansas.

NDE methods for API 653 work in Kansas

Direct answer: Kansas tank work relies on floor MFL scanning with UT prove-up, shell and annular-plate UT, corrosion mapping on insulated and heated tanks, visual examination of roofs, seals and foundations, MT, PT and vacuum-box testing after repairs, PAUT or RT on new welds, and settlement survey data for the inspector.

Procedures are reviewed by an ASNT NDT Level III and technicians are certified to an SNT-TC-1A written practice for each method. Every reportable MFL indication is proved up with UT. Crude tanks that receive gathered oil often carry water and sediment that concentrate corrosion near the floor and the lower shell course, so floor and lower-course data deserve particular care. For the floor-method trade-offs see MFL versus UT for tank floors, and for the full scope see aboveground storage tank inspection.

How Atlantis supports your Authorized Inspector

Direct answer: Atlantis takes the scope from your API 653 inspector's plan, performs the NDE, checks the data before leaving site and delivers a digital report the inspector can evaluate and sign. We are not an Authorized Inspection Agency and we do not supply API-certified inspectors. That separation suits Kansas operators who already have an inspector or agency and need dependable NDE crews behind them.

1. Scope from the inspector's plan: floor coverage, shell and annular-plate locations, roof, seal and foundation examinations, weld examinations and settlement points.
2. Procedure review by an ASNT NDT Level III, matched to the tank's construction standard and the inspector's acceptance references.
3. Examinations by technicians certified to an SNT-TC-1A written practice: MFL with UT prove-up, shell and annular UT, corrosion mapping, visual, surface and volumetric methods.
4. Data QA on site: readings checked against calibration records and the last inspection before demobilising.
5. Digital report in our reporting platform: floor maps, prove-up readings, shell readings by course, weld records, photographs, calibration data and technician certifications, on report templates that suit your inspector's file and your SPCC or PHMSA records.
6. Inspector evaluation and sign-off: the inspector evaluates the results, decides on repairs and sets the next dates.
7. Reuse at the next interval: the same locations next time, tracked in our inspection-management ERP or a digital twin of the tank farm.

Corrosion rates and remaining life can be calculated from our thickness data for the inspector's review; the interval decision is the inspector's and the owner's under API 653 and the rule that applies. Atlantis performs the NDE; your API 653 Authorized Inspector remains inspector of record and signs the inspection report. Request an NDE scope for your inspector's plan, or see API 653 tank inspection support.

Planning around turnarounds, harvest and prairie weather

Direct answer: In Kansas, out-of-service tank inspections are usually planned for spring and autumn, when temperatures suit confined-space work and UT, and aligned with refinery turnarounds, pipeline schedules and, for agricultural and ethanol sites, the harvest and fertilizer seasons. In-service external work can run most of the year with weather allowances.

Refinery turnarounds. At Coffeyville, El Dorado and McPherson, tank work is often scheduled around unit turnarounds and seasonal product slates, with crude tanks rotated out of service while others carry throughput. Heated asphalt and residual tanks need cool-down time and insulation removal before UT.

Harvest and fertilizer seasons. Ethanol plants run hardest after harvest, and fertilizer storage is full ahead of spring and autumn application. Taking a nitrogen-solution or ethanol tank out of service needs to fit those cycles, so internal inspections are usually planned for the quieter months.

Heat, cold, wind and hail. Kansas summers bring extreme heat inside tanks and on sunlit shells, and winters bring hard freezes that affect UT couplants, temperature correction and technician safety. High winds limit work at height and on floating roofs, and severe hailstorms can damage coatings and roofs across a whole tank farm, after which owners often want a visual survey. Atlantis plans crews around these conditions with temperature-corrected procedures and weather allowances in the schedule.

Cleaning and prove-up. As everywhere, the biggest saving on an internal inspection comes from scheduling cleaning, floor scanning, UT prove-up, the inspector's evaluation and the repair crew as one sequence. Book a scoping call to build that sequence for your next outage.

Frequently asked questions: API 653 tank inspection in Kansas

Who can perform an API 653 inspection in Kansas?

An API 653 Authorized Inspector, employed by the owner or an inspection agency, is responsible for the inspection and signs the report. Qualified NDE technicians collect the data. Atlantis performs that NDE with ASNT-certified technicians under Level III oversight and delivers the results to your inspector.

Do I need a KDHE permit for my aboveground tank?

Nonexempt ASTs storing petroleum fuels, flammable or combustible liquids, listed hazardous substances or used oil must be registered with KDHE and carry a valid annual operating permit. New flammable-liquid tanks also need State Fire Marshal approval before construction. Confirm exemptions and current procedures with KDHE.

Are refinery and pipeline terminal tanks regulated by KDHE?

No. KDHE's AST programme exempts tanks at petroleum refining facilities, pipeline terminals, DOT-regulated pipeline facilities and oil and gas production sites. Those tanks still fall under EPA SPCC, PHMSA or OSHA PSM where they apply.

Is API 653 required by law in Kansas?

It is required in effect wherever EPA's SPCC rule, PHMSA's breakout-tank rule at 49 CFR 195.432 or OSHA PSM applies, and wherever the owner's standard adopts it. KDHE's AST rules focus on registration and permitting rather than integrity inspection.

Who regulates pipeline breakout tanks in Kansas?

PHMSA, directly. Kansas has not taken on intrastate hazardous-liquid pipeline authority, so PHMSA inspects both interstate and intrastate liquid lines. Their atmospheric breakout tanks must be inspected in accordance with API 653 without the risk-based internal interval.

Do oil-lease tank batteries need API 653 inspections?

Usually not. Production tanks are typically built to API 12-series specifications and managed under API RP 12R1. They are exempt from KDHE's AST rules, but SPCC can still apply to production facilities. Check your SPCC plan.

How often does a storage tank need an API 653 inspection?

Monthly owner checks, an external inspection at least every five years, shell UT on an interval set by corrosion rate, and an internal inspection first due within ten years, then on a calculated interval within the code's ceilings. The inspector sets the dates.

Is Atlantis an Authorized Inspector?

No. We are not an Authorized Inspection Agency and we do not supply API-certified inspectors. We perform and document the NDE; your inspector evaluates it and signs.

What certifications do your NDE technicians hold?

Technicians are certified to an ASNT SNT-TC-1A written practice for each method, with procedures reviewed by an ASNT NDT Level III. Radiography is performed only by crews licensed through KDHE's Radiation Control Program.

Do you perform RBI or fitness-for-service assessments?

No. Those are carried out by the owner's engineers or specialist consultants. Atlantis supplies the floor, shell and weld data they use.

Do you offer API 653 certification training?

No. Atlantis provides ASNT SNT-TC-1A NDT training only, including NDT training in Kansas. For the API certification route, see our API inspector career guide.

How quickly can a crew reach Coffeyville, El Dorado or McPherson?

Crews are mobilised to your site on a schedule agreed during scoping, built around cleaning, turnaround and pipeline dates. Send tank details for a quote within 24 hours.
