Storage Tank services

Above ground and underground storage tank services

Storage tanks—whether underground or above ground—carry significant environmental and regulatory responsibilities. Leaking underground storage tanks (USTs) can contaminate soil and groundwater, while above ground storage tanks (ASTs) require strict compliance with spill prevention and tank monitoring requirements. EIS helps clients manage these risks from start to finish, providing expert support for storage tank installation, maintenance, and closure.

We deliver comprehensive storage tank services for retail gas stations, convenience stores, fuel suppliers, bulk plants, manufacturers, military installations, and commercial property owners nationwide.

Our Approach to Storage Tank Services

END-TO-END PROJECT MANAGEMENT

Storage tank projects involve multiple phases—system design, regulatory permitting, system construction, tank testing, and ongoing maintenance. EIS manages every step, providing a single point of accountability from UST installation through tank closure. Whether installing new tanks or closing old ones, we ensure your project moves forward without delays or gaps.

TECHNICAL EXPERTISE & CERTIFICATIONS

Fuel systems are complex, and mistakes can be costly. Our team holds various certifications such as Steek Tank Institute (STI) SP001 AST System Inspector certifications and has decades of hands-on experience with tank monitoring equipment, leak detection systems, and compliance repairs. We bring specialized knowledge to every job, from STP corrosion abatement and spill bucket replacement to full fuel system maintenance.

REGULATORY & STORAGE TANK COMPLIANCE

UST and AST rules vary significantly by state, and keeping up with changing requirements is challenging. EIS stays current with underground storage tank regulations and above ground storage tank compliance, so you don’t have to. We handle permit applications, compliance reporting, and violation resolution, and we ensure your tanks remain eligible for state petroleum reimbursement programs should a leak ever occur
