Underground Storage Tank Support
Underground storage tank change-outs, upgrades, and AST transitions
KPM helps owners change out underground storage tanks, modernize aging UST systems, and plan practical conversions to aboveground storage tanks when site access, lifecycle cost, or compliance strategy points to a better long-term solution.
How KPM supports UST change-out projects
We support owners dealing with tank end-of-life, fueling system reconfiguration, and modernization work that needs to be executed safely, cleanly, and with minimal operational disruption.
Replace Existing USTs
Remove aging tanks, coordinate closure activities, and install new underground storage systems with updated monitoring, piping, and dispenser connections.
Transition to ASTs
Rework your site from below-grade storage to aboveground systems when accessibility, containment, maintainability, or operating strategy makes ASTs the better fit.
Upgrade In Place
Improve leak detection, spill and overfill protection, tank tops, piping, sumps, and controls when a full replacement is not the right first move.
Project Focus
From removal planning to the next storage strategy
Whether the right answer is a new UST, a staged migration to ASTs, or targeted upgrades to keep the current underground system operating safely, KPM can support the mechanical scope that moves the project forward.
- Coordinate change-out sequencing around active operations and site access
- Plan the mechanical transition from existing underground systems to new storage layouts
- Integrate tank, piping, equipment, and startup scopes into one field-ready package
Typical project scope
Underground tank change-outs tend to touch more than the tank itself. The surrounding systems, connections, and operating constraints usually drive how the project should be sequenced.
Site review, constructability, and change-out planning
UST closure sequencing and excavation support coordination
Tank removal, replacement, or AST transition layout planning
Product piping, venting, electrical, controls, and tie-ins
Containment, monitoring, and equipment upgrade integration
Startup support, punch-list closeout, and turnover documentation
Dewatering & Inspection
Groundwater conditions can change the removal plan fast
When water is present around an underground tank, the field team has to determine what is there, how it affects access and safety, and whether it needs to be removed and routed for further handling before the tank can come out cleanly.
- Inspect water conditions around the exposed tank during excavation and removal planning
- Support dewatering when clean or contaminated groundwater is affecting access to the tank
- Coordinate water handling with the broader tank draining, testing, and removal sequence
When owners consider a change-out
- Aging tanks or piping are driving lifecycle and maintenance concerns
- Leak detection, spill protection, or compliance systems need major updates
- Site redevelopment or fueling layout changes make ASTs more practical
- Access for inspection, maintenance, and future modifications is limited below grade
Coordination that matters
- UST rules, state and local permitting, and closure documentation affect schedule
- Environmental sampling and specialty closure scopes often need tight field coordination
- Temporary fuel continuity, dispenser downtime, and cutover windows should be planned early
- AST transition projects must also address containment, access, and revised piping routing
