Fuel-system design, permitting and compliance as one defined path.
Design first. Build with confidence. Equipment selections, system configuration and AHJ requirements are settled during design, not left for resolution in the field. Serving clients nationwide.
From a petroleum-storage problem to a permitted, constructible fuel system.
Our services are grouped around where they fit in the life of a fuel-system project. Where permitting is required, it is integrated into the design process rather than treated as an afterthought.
Fuel-system design
Detailed, code-vetted designs that give contractors a clear roadmap for construction.

Fuel System Design
Complete, constructible fuel-system designs with equipment, configuration, codes and AHJ requirements vetted before the contractor prices the job.

UST System Design
Underground storage tank systems: tank, piping, sumps, leak detection and dispensing, designed to the applicable federal, state and county rules.
View service
AST System Design
Aboveground storage tank systems for fuel, fuel oil, waste oil and generator diesel, sized and sited to fire code and AHJ requirements.
View service
Fuel Piping and Dispensing Systems
Product piping, dispensers, sumps, vapor recovery and fuel-management interfaces designed as one coordinated system.
View service
Fuel Management Systems
Fuel-control, tank-gauging and monitoring system selection and integration for fleet, municipal and commercial fueling.
View service
Fuel System Upgrades and Replacements
Aging tank replacement, capacity expansion, UST-to-AST conversion, sump replacement and overfill or containment corrections.
View service
Permitting and compliance
Permit due diligence, AHJ approvals, violation resolution and ongoing regulatory obligations.

Fuel Tank Permitting
Permit due diligence and approvals from every authority having jurisdiction, handled as part of the design rather than an afterthought.
View service
Compliance and Violation Resolution
Petroleum storage violations, unpermitted installations, failed tests and occupancy holds resolved with a defined corrective path.
View service
PBS Registration and Renewal
NYSDEC Petroleum Bulk Storage registrations, renewals and modifications kept current and accurate.
View service
SPCC Plans
Spill Prevention, Control and Countermeasure plans under 40 CFR 112, with containment design coordinated to the facility.
View service
Tank Closure and Decommissioning
UST and AST closure planning, agency notification and deregistration with a clean file at the end.
View service
Construction and technical support
Owner representation through construction, and behind-the-scenes specialist support for other firms.

Construction Support and Owner Representation
Bid review, submittal review, field questions and closeout on the owner's side of the table.

Technical Design Support for Firms
Fuel-system specialist support for engineering firms, architects, consultants and petroleum contractors, behind the scenes.

Equipment selections, system configurations and regulatory requirements are evaluated during design rather than left for the field.
Design first. Build with confidence.
Detailed fuel-system designs give contractors a clear roadmap for construction. For an owner, that means six practical things.
A compliant, functional system
Designed to the applicable codes and to how the facility actually fuels.
Permitted around the real AHJs
Designed and permitted to the specific requirements of the authorities that will inspect it.
A clearly defined construction scope
Equipment, configuration and sequence are on the drawings before anyone prices the job.
Fewer field assumptions
Less troubleshooting on site because the questions were answered during design.
Fewer avoidable change orders
Selections settled up front do not turn into surprises halfway through construction.
Better contractor bids
Every bidder is pricing substantially the same defined system, so numbers are comparable.
The owner, the contractor and the project team.
ZE is the independent fuel-system specialist. It works directly for the owner or alongside the contractor and design team, and understands what each side needs from the same set of drawings.
Facility owners and operators
You own or run the site and need a tank permitted, a violation cleared or a system replaced. ZE works for you directly: investigation, design, AHJ approvals and a defined scope you can put out to comparable contractor bids.
Start with fuel-system designPetroleum contractors
Much of ZE's work arrives through contractors. Bring the site and the owner's goal; ZE produces the design set and carries the permit so your crew builds from vetted drawings instead of resolving equipment and code questions in the field.
Design support for contractorsEngineering firms, architects and consultants
When a larger project touches a fuel system, ZE is the specialist behind the scenes: UST and AST design, fire-code and county health requirements, and coordination with appropriately licensed Professional Engineers when professional engineering review or certification is required.
Technical design support for firmsZambrano Enterprises provides specialized fuel-system design and technical consulting services. When professional engineering review or certification is required, ZE coordinates with appropriately licensed Professional Engineers through established professional relationships nationwide.
