How the NJCAT Verification Process Works
The NJCAT verification process has been carefully refined over the years to provide a reliable and detailed evaluation system for stormwater management technologies. Since its inception in 2001, it has grown into one of the most respected programs of its kind in the United States [3].
At the heart of the process is independent third-party validation. This means that unbiased experts assess the performance claims made by vendors, ensuring a balance between scientific rigor and practical application [2].
Step-by-Step Verification Process
The journey starts with a $1,000 Limited Preliminary Application, which helps determine if the system is ready for evaluation. Once accepted, the vendor enrolls in the Stormwater Treatment Systems Program, paying a total fee of $20,000 in four manageable $5,000 installments [2]. This payment plan allows companies to budget effectively while committing to the process.
The core of the verification process unfolds in several stages. Initially, NJCAT conducts a thorough review of the system’s technical specifications, design parameters, and preliminary performance data. Next, the system’s performance claims are tested against established protocols to verify their accuracy [5]. Finally, NJCAT compiles all findings into a detailed verification report, which serves as the foundation for NJDEP certification [5].
Once the application is reviewed and fees are processed, NJCAT rigorously tests the system’s performance to ensure it aligns with environmental standards.
Testing Protocols and Performance Standards
NJCAT’s testing protocols are designed to verify that manufactured treatment devices (MTDs) meet New Jersey’s stringent environmental regulations [3]. These tests focus on critical factors like removing suspended solids, reducing pollutant loads, and assessing maintenance needs.
The program actively incorporates feedback from the private sector during technology development, testing, and commercialization [3]. This collaborative approach ensures that testing reflects real-world conditions while maintaining the scientific precision needed for regulatory compliance.
Performance standards are directly tied to New Jersey’s stormwater management rules (N.J.A.C. 7:8-5.2(j)). These rules require hydrodynamic and filtration MTDs to achieve NJCAT verification before they can receive NJDEP certification [3]. This ensures that only verified systems are approved for stormwater compliance in the state.
For major development projects, the stakes are even higher. When a project triggers the requirements of the Stormwater Management rule (N.J.A.C. 7:8), an MTD must not only be NJCAT verified but also NJDEP certified [4]. This dual certification guarantees that systems meet both performance expectations and regulatory mandates.
2022 Updates to NJCAT Protocols
In 2022, NJCAT introduced updates to its protocols, building on over two decades of experience. These changes aim to address new challenges in stormwater management while aligning more closely with industry standards.
One notable update involves the adoption of the Natural Resources Conservation Service (NRCS) methodology for sizing calculations. This replaces the older Rational Method in certification letters, as outlined in Chapters 9.5 and 11.3 of the NJDEP BMP Manual [4]. This shift provides more precise sizing guidance, ensuring that verified systems are appropriately scaled for their intended use.
These updates also enhance vendor credibility and boost confidence among regulators and end-users [5]. By refining methodologies and evaluation criteria, the process has become more predictable for manufacturers and more dependable for municipalities and engineers selecting stormwater solutions.
Through these updates, NJCAT continues to fulfill its mission of supporting the development of energy and environmental technologies. By verifying performance claims against regulatory standards, the program ensures that manufacturers, municipalities, and engineers can rely on stormwater management systems that meet both environmental and practical needs [5].
Pros and Cons of NJCAT-Verified Filtration Systems
When tackling stormwater management, understanding the differences between NJCAT-verified and non-verified systems is essential. Each option has its strengths and challenges, and evaluating these trade-offs helps property owners and engineers make better decisions.

While these benefits are significant, it’s important to weigh them against the challenges that come with NJCAT-verified systems.
Drawbacks to Consider
Despite their advantages, NJCAT-verified systems come with some notable challenges:
- Complex Evaluations: Assessing stormwater technologies is inherently difficult. As NJCAT explains:
"Stormwater Management Technologies in particular are difficult to evaluate. Pollutant removal performance depends upon many factors, e.g., influent particulate size distribution, influent pollutant concentration (loading), stormwater flow rate, sump design and capacity, and maintenance" [1].
- Sizing Issues: Proper sizing is critical. Undersized manufactured treatment devices (MTDs) can underperform, leading to frequent maintenance and higher costs. On the other hand, oversized systems take up more space, complicate retrofits, and increase project expenses [6].
- Higher Upfront Costs: NJCAT-verified systems often come with a higher price tag. However, their smaller footprint can offset costs in some cases. For instance, systems like FocalPoint filter runoff at over 100 inches per hour per square foot, compared to traditional systems that manage just 1–4 inches per hour. This efficiency allows FocalPoint systems to be up to 30 times smaller than detention pond solutions [7].
- Testing Variability: A lack of standardized sediment particle size for testing can lead to inconsistent performance under different conditions, creating confusion for stakeholders [6].
NJCAT-Verified vs. Non-Verified Systems Comparison
Here’s a side-by-side look at how NJCAT-verified systems stack up against non-verified systems:
