Nassau County Article XV petroleum storage compliance
A plain-English guide to Nassau County Department of Health Article XV petroleum storage rules — registration, permits, secondary containment, testing, and how it stacks on NYSDEC Part 613.
If you store petroleum in Nassau County, you answer to two regulators, not one. The state runs the NYSDEC Petroleum Bulk Storage program under 6 NYCRR Part 613, and Nassau County layers its own Department of Health code on top: Article XV of the Public Health Ordinance, the county's Toxic and Hazardous Materials Storage and Handling Code. Article XV is stricter than the state baseline because all of Nassau sits over a federally designated sole-source aquifer — the drinking water is directly under the tanks.
In practice that means a Nassau facility needs a county Department of Health permit to store, handle, or dispose of petroleum, on top of its state PBS registration. The county sets its own rules for secondary containment, leak monitoring, tightness testing, and recordkeeping, and it inspects on its own schedule. Meeting Part 613 does not automatically satisfy Article XV, and a clean state file will not clear a county violation.
We prepare, file, and certify the work on both sides — county permit applications, secondary-containment and monitoring design, the testing that the Health Department wants to see, and the PBS registration that has to match it. This guide explains how Article XV applies to petroleum tanks, where it overlaps with the state program, and where it goes further.
What Article XV is, and why Nassau regulates separately
Article XV is the storage-and-handling code in the Nassau County Public Health Ordinance, administered by the Nassau County Department of Health. It governs how toxic and hazardous materials — petroleum among them — are stored, handled, transferred, and disposed of across the county. Petroleum tanks fall under it because gasoline, diesel, fuel oil, kerosene, and waste oil are exactly the materials the code is built to keep out of the ground.
The reason Nassau has its own code at all comes down to hydrogeology. Long Island draws its drinking water from an aquifer system that the U.S. EPA designated a sole-source aquifer, meaning there is no practical alternate supply if it is contaminated. A petroleum release that would be a contained cleanup elsewhere can reach the water table fast here. So Nassau, like Suffolk next door, writes local storage rules that go beyond the state minimum and enforces them through the Health Department rather than waiting on Albany.
Registration and permits: what the county requires
A Nassau petroleum facility needs a Department of Health permit to store and handle the product. The county reviews the facility, issues the permit for a set term, and renews it on a cycle — and it expects the facility's records to match what is in the field on each renewal and inspection.
New installations, tank replacements, upgrades, and closures generally require county approval before the work starts, in addition to any town building and fire permits. The Health Department wants to see the system design, the containment and monitoring approach, and the closure or installation plan up front. Filing the state PBS registration does not substitute for this — the two programs run in parallel and both have to be current.
- Department of Health storage-and-handling permit for the facility, kept current and renewed on the county's cycle
- County approval for installations, replacements, upgrades, and tank closures before work begins
- Facility and tank data on file that matches the physical site and the NYSDEC PBS registration
- Application packages with system design, containment, monitoring, and closure or installation details
Secondary containment and leak prevention
Secondary containment is the core of Article XV. The county's premise is simple: if the primary tank or piping fails, a second barrier has to catch the release before it reaches soil or groundwater. For underground systems that means double-wall tanks and double-wall (secondarily contained) piping with the interstitial space monitored. For aboveground tanks it means double-wall construction or a containment dike or vault sized to hold the contents, plus protection from spills at the fill and dispensing points.
This is where county and state requirements largely point the same direction but the county holds the detail. Secondary containment, spill buckets at fill ports, overfill protection, and protected dispensing areas are all expected, and the county inspects to confirm they are present and working — not just drawn on a plan.
- Double-wall tanks and secondarily contained piping for underground systems
- Double-wall, diked, or vaulted containment for aboveground tanks, sized to hold the stored volume
- Spill containment (catch basins) at fill ports and overfill prevention on every tank
- Containment sumps and dispenser pans kept liquid-tight and monitored
Testing and monitoring
Article XV facilities are tested and monitored on an ongoing basis, and the county wants the results. Tank and piping tightness testing confirms the system is not leaking; interstitial monitoring on double-wall equipment, automatic tank gauging, and sump and dispenser-pan integrity testing catch a release early. The exact methods and intervals depend on the system, but the through-line is documentation: a test or monitoring record that the Health Department can review on inspection.
A failed tightness test or a positive leak signal is not a paperwork problem — it is a release-prevention problem, and it triggers reporting and corrective action under both the county code and the state program. The fastest way to turn a single failed test into an enforcement file is to leave it unaddressed.
How Article XV stacks on NYSDEC Part 613
Think of it as layers. NYSDEC Part 613 (6 NYCRR Part 613) is the statewide Petroleum Bulk Storage standard — registration with the state, design and equipment requirements, testing, recordkeeping, and closure. Article XV is the Nassau County overlay, enforced by the Health Department, and it meets or exceeds the state floor while adding its own permit, its own inspections, and its own filings.
For a facility that stores enough product, a third layer applies: the federal SPCC rule under 40 CFR 112, which requires a Spill Prevention, Control, and Countermeasure plan for sites above the aggregate aboveground threshold. None of these replaces the others. A Nassau petroleum facility commonly has to satisfy the county permit, the state PBS registration, and — where it applies — an SPCC plan, all at once and all consistent with each other.
- NYSDEC Part 613 — statewide PBS registration, design, testing, and closure rules
- Nassau County Article XV — county Health Department permit, containment, and inspections on top
- Federal SPCC (40 CFR 112) — spill-prevention plan where aboveground storage exceeds the threshold
- All three must align: the same tank, the same numbers, no contradictions across filings
How we handle Nassau Article XV work
We treat the county and state requirements as one job, because the regulators do not accept inconsistencies between them. As a Georgia Tech engineer with fifteen-plus years in petroleum bulk storage, Matt Zambrano prepares the design, files the permits, and certifies the work that Nassau and NYSDEC expect to see.
That means county Department of Health permit applications, secondary-containment and monitoring design and drafting, coordination of tightness testing, the PBS registration that has to match the field, and a clean response when a Notice of Violation or a failed test puts a deal or a certificate of occupancy on hold. The goal is straightforward: a facility that passes inspection, a file that is defensible, and a transaction that closes.
- Nassau County DOH permit applications, renewals, and installation or closure approvals
- Secondary-containment and leak-monitoring design and drafting for UST and AST systems
- Coordination of tightness testing and monitoring, with records the county will accept
- Aligned NYSDEC PBS registration and, where required, an SPCC plan
- Violation response and corrective-action plans to clear enforcement and C of O holds
Common questions
Do I need a Nassau County permit if I already have a NYSDEC PBS registration?
Yes. The state PBS registration under Part 613 and the Nassau County Department of Health Article XV permit are separate requirements that run in parallel. Holding one does not satisfy the other. A petroleum facility in Nassau generally needs both kept current at the same time, and the data on each has to match.
What does Article XV actually regulate?
Article XV is Nassau County's Toxic and Hazardous Materials Storage and Handling Code, administered by the county Health Department. For petroleum it governs the permit to store and handle the product, secondary containment, leak monitoring and testing, recordkeeping, and the approval needed to install, upgrade, or close tanks.
Why is Nassau County stricter than the rest of New York?
Nassau sits over a federally designated sole-source aquifer — the same groundwater under the tanks is the drinking-water supply, with no practical alternative if it is contaminated. That hydrogeology is why Nassau, like Suffolk, enforces a local storage code that goes beyond the statewide Part 613 minimum.
Does Article XV require secondary containment on my tanks?
Yes. Secondary containment is central to the code. Underground systems are expected to be double-wall with monitored interstitial space and secondarily contained piping. Aboveground tanks need double-wall, diked, or vaulted containment sized to the stored volume, plus spill buckets and overfill protection at the fill and dispensing points.
Do I need an SPCC plan as well?
Possibly. The federal SPCC rule (40 CFR 112) applies when a site's aggregate aboveground petroleum storage exceeds the federal threshold, and it is separate from both Article XV and Part 613. Many Nassau facilities carry all three. We confirm whether SPCC applies to your site and prepare the plan if it does.
I got a Nassau County Department of Health notice on my tanks. What now?
Address it quickly and on both fronts. A county finding — a failed tightness test, missing records, or a containment deficiency — often has a Part 613 dimension too, and it can hold up a sale or a certificate of occupancy. We prepare the corrective-action plan, the design or repairs needed, and the filings to clear the violation with the county and the state together.
