Working With Zambrano Enterprises
Designer or contractor first, sealed drawings, what to send, how permitting fits design.
Do I need a designer or a contractor first?
For most projects, the design comes first. A contractor needs a defined system to price. Without a design, each bidder makes their own assumptions about tank type, piping, sumps, monitoring and what the AHJ will require, and the bids are not comparable. With a design, everyone prices substantially the same system, the permit application is built on that design, and there is less to work out in the field. If you already have a contractor you trust, we work alongside them. Many of our projects come to us through petroleum contractors.
Do you stamp drawings?
No. Zambrano 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. Matt Zambrano holds a B.S. in Civil Engineering from Georgia Tech and performs the technical design work.
Do you work directly for owners or through contractors?
Both. We work directly for facility owners and operators as their independent design and technical specialist, and we work alongside petroleum contractors, engineering firms, architects and consultants as the fuel-system specialist on their team. Contractors are partners, part of the project team. Either way, the goal is the same: a permitted, compliant, constructible system with a scope everyone understands.
What should I send with my inquiry?
Whatever you have. Photos of the tank, the fill area and the dispensers, the violation notice or inspection report if there is one, any existing drawings or registrations, the site address and a sentence about what you are trying to do. You do not need to know which regulations apply. Sorting that out is the first thing we do.
How does permitting fit into design?
Where permitting is required, it is integrated into the design process rather than treated as an afterthought. Before we design, we confirm which agencies have jurisdiction and what each will require, because those requirements drive tank type, containment, monitoring, setbacks and dispensing layout. The design is then built to satisfy those requirements, and the permit application is built on the design. Doing it in that order avoids redesigning after review comments and avoids field changes after the permit is issued.
Do you support other engineering and consulting firms?
Yes. Zambrano Enterprises routinely works behind the scenes as the fuel-system specialist for engineering firms, architects, consultants and petroleum contractors who need UST, AST, piping, dispensing or fuel-management design and permitting expertise on their project. That work is done under the lead firm's project and is not marketed as a ZE project.
Scope and Coverage
What we take on and where we work.
What types of projects does Zambrano Enterprises handle?
Fuel-system design, tank permitting, regulatory compliance, violation resolution, system upgrades and replacements, and construction support. That covers underground (UST) and aboveground (AST) storage tank systems, fuel piping and dispensing, fuel management systems, and the diesel tanks that serve emergency generators. Typical projects include aging tank replacement, storage capacity expansion, UST-to-AST conversion, failed sump replacement, legalization of unpermitted installations, AST relocation to a new facility, and motor-oil, waste-oil and lubrication storage at automotive facilities.
What areas do you cover?
Specialized fuel-system design, permitting and compliance support nationwide. Zambrano Enterprises is based in Central Virginia and serves clients across the country. The deepest concentration of regulatory experience is in New York: Long Island (Suffolk County under SCDHS Articles 7, 12 and 18 and Nassau County under Article XV of the Nassau County Public Health Ordinance), Westchester County, New York City and the Hudson Valley, plus NYSDEC Part 613 statewide. When a project needs professional engineering review or certification, ZE coordinates with appropriately licensed Professional Engineers through established professional relationships nationwide.
Do you work with retail service stations, fleet yards, or both?
Both, plus automotive repair and service facilities, rental car return-lane fueling, emergency generator fuel systems, marinas, aviation fueling and commercial or industrial bulk storage. The rules are largely the same across them. The operational priorities differ, and the design reflects that.
Do you cover diesel emergency generator fuel systems?
Yes. Diesel USTs and ASTs, day tanks, sub-base tanks, fuel supply and return piping, and NFPA 30, 30A and 110 requirements, coordinated with the generator package. Generator tanks are a common source of violations because they were installed with the generator and never registered or permitted as a fuel-storage system.
Process and Permitting
How a project moves from site walk to permit.
How does the permitting process work?
Permitting starts during design, not after it. We identify every authority having jurisdiction for the site, confirm what each one requires, and design the system around those requirements. Then we prepare the application package, submit it, respond to review comments and carry it through to permit issuance and final inspection. You know which agencies are involved and where the application stands at each step.
Which agencies do you regularly work with?
Suffolk County Department of Health Services (SCDHS, Articles 7, 12 and 18), Nassau County Department of Health (NCDH, Article XV), Westchester County Department of Health (WCDOH, Article XXV), NYSDEC (6 NYCRR Part 613 petroleum bulk storage), FDNY and the NYC Department of Buildings where a New York City project calls for them, Virginia DEQ (9VAC25-580 and 9VAC25-91), the Virginia State Fire Marshal, and local building departments and fire marshals. On a project in any other state, ZE identifies the authorities having jurisdiction at that site and works with them the same way.
How does your design process work?
We start by investigating the site and the existing system, then set a compliance and design strategy with you before drawing anything. The design covers the tank, piping, sumps, leak detection, dispensing, fuel management and the AHJ requirements for that specific site, so equipment selections and configurations are settled during design rather than left for the contractor to figure out in the field. The result is a defined scope a contractor can price and build from.
Can you help with variances?
Yes. When a site cannot meet a setback, tank type, signage or other code requirement as written, we prepare the variance application, the technical narrative and the supporting drawings, and support the owner through the agency's review or hearing.
Compliance and Getting Started
Closing open issues and the first step with us.
What happens when we receive a tank violation?
Most tank violations are not about a leak. They are about missing or expired registrations, a test that was not performed or documented, a spill bucket or overfill device that failed, a sump with water in it, or equipment that was changed without the agency being told. We read the notice, sort the items into paperwork, testing and equipment, get the right corrective path in front of the agency before the response deadline, design and permit whatever physical work is needed, and close the file in writing.
How do I get started?
Call (845) 642-7754 or email matt@zambranoen.com. Tell us where the site is, what you are trying to accomplish and the current status. Matt remains directly involved in the technical design and client coordination from the first conversation through closeout. Most inquiries receive a response within one business day. The next step is usually a short call followed by a site visit.
Still have questions?
Matt is directly involved from the first conversation, whether that is a quick scoping call or a full site walk.
