EPA vs. NJDEP Rules for UST Closure: What’s Different in New Jersey?

Closing an underground storage tank (UST) is governed at the federal level by 40 CFR Part 280, Subpart G, but in New Jersey, the process does not stop there. The New Jersey Department of Environmental Protection (NJDEP) has adopted the federal framework and then expanded it significantly through N.J.A.C. 7:14B and related remediation rules.

For property owners and operators, the distinction matters. While EPA rules establish the baseline for safe closure, New Jersey imposes additional layers of oversight, professional licensing, and technical rigor. The underground storage tank experts at Herbert Lutz & Co. routinely work within this dual regulatory structure, helping clients meet both federal standards and the stricter NJDEP requirements.

Where NJDEP Mirrors EPA Closure Requirements

At a foundational level, New Jersey follows the same core closure principles established by the EPA. These include requirements for properly taking a tank out of service, removing product and sludge, and evaluating the site for contamination.

Like the EPA, NJDEP requires that tanks be emptied and cleaned prior to closure, whether the tank is removed or abandoned in place. Both regulatory schemes also require advance notice to the implementing agency before permanent closure activities begin. In New Jersey, that agency is NJDEP or, in some cases, the local authority with delegated oversight.

Another major point of alignment is the requirement for a site assessment at closure. Just as federal rules require owners to evaluate areas where contamination is most likely, New Jersey mandates sampling in and around the tank basin and piping areas to determine whether a discharge has occurred. If contamination is identified, both EPA and NJDEP frameworks require corrective action under separate remediation rules.

Temporary closure rules also closely track federal standards. Tanks taken out of service must remain protected against corrosion and, depending on conditions, may still require leak detection unless properly emptied. After a certain period out of service, both EPA and NJDEP rules require either return to compliance or permanent closure.

In short, if you understand EPA closure rules, you already understand the structural foundation of New Jersey’s approach. However, that is only the starting point.

Where NJDEP Expands on Federal Requirements

New Jersey goes well beyond federal requirements in several key areas, particularly in how closure work is performed, who is allowed to perform it, and how contamination is investigated and documented.

Mandatory Contractor Certification

One of the most significant differences is that New Jersey requires formal certification for both individuals and firms performing UST work, including closure. Under N.J.A.C. 7:14B, no one can legally install, test, or close a UST unless they are certified by NJDEP and employed by a certified firm. This is not simply a licensing formality. Certification requires documented experience, training, and in many cases, successful completion of examinations. Firms must also demonstrate financial assurance and maintain certified personnel in relevant categories.

By contrast, the EPA rules do not impose a national contractor certification requirement for UST closure. That responsibility is largely delegated to states, and New Jersey has chosen a far more structured and restrictive approach.

Required Use of Licensed Site Remediation Professionals (LSRPs)

Another major expansion is New Jersey’s requirement that Licensed Site Remediation Professionals (LSRPs) oversee environmental investigations associated with UST closures. Since regulatory changes implemented in 2009 and strengthened thereafter, any UST closure involving potential contamination must involve an LSRP. These professionals are responsible for directing the investigation, interpreting sampling data, determining the extent of contamination, and preparing remediation reports.

This is a fundamental difference from federal rules. Under EPA regulations, site assessments must be performed, but there is no nationwide requirement that a state-licensed environmental professional oversee the work. New Jersey’s LSRP program effectively privatizes and professionalizes oversight, while still holding those professionals accountable to NJDEP standards.

More Prescriptive Sampling and Investigation Standards

EPA rules require a site assessment but leave flexibility in how sampling is conducted. New Jersey, by contrast, imposes detailed technical requirements through its site remediation regulations, including N.J.A.C. 7:26E.

These rules dictate:

• Where samples must be collected (e.g., beneath the tank, along piping runs)
• How many samples are required based on tank size and configuration
• Analytical methods and reporting standards
• Documentation and reporting formats

Sampling is not a general obligation in New Jersey; it is a structured, rule-driven process. The involvement of an LSRP ensures that these standards are followed and that the investigation meets NJDEP expectations.

Integrated Remediation Oversight

Under EPA rules, closure and corrective action are linked but somewhat separate processes. In New Jersey, they are tightly integrated through the state’s broader site remediation program. If contamination is identified during closure, the case immediately transitions into NJDEP’s remediation framework. The LSRP oversees the process from initial investigation through final reporting, often culminating in a Remedial Action Outcome (RAO) rather than direct NJDEP sign-off in routine cases. This system creates continuity from closure through remediation, but it also increases the level of documentation, technical review, and professional accountability required.

Enforcement and Compliance Structure

New Jersey also maintains an active enforcement program specifically focused on UST compliance, including closure requirements. The NJDEP Bureau of Underground Storage Tank Compliance and Enforcement conducts inspections, investigates violations, and issues penalties when rules are not followed. Because closure activities involve certified contractors and LSRPs, enforcement can extend beyond property owners to include professionals who fail to meet regulatory standards.

Why These Differences Matter

From a practical standpoint, closing a UST in New Jersey is more complex and more regulated than in many other states. The process requires coordination between certified contractors, environmental professionals, and regulatory frameworks that go beyond federal minimums.

For property owners, this means:

• You cannot legally perform or hire unqualified contractors for tank closure
• Environmental investigation is not optional if contamination is suspected
• Documentation and reporting must meet strict NJDEP standards
• Liability exposure is higher if closure is not handled properly

These requirements are designed to reduce environmental risk, but they also raise the stakes for getting the process right the first time.
