NJDEP Common Control

Typically, when a facility is applying for an air permit in the state of New Jersey, it is one entity which operates on a single site. However, there are some circumstances in which two entities can co-exist on a single site, contiguous, or adjacent site; whether they are two separate companies at the same physical location or a single company which has subdivided its operations for business, tax, or company purposes. Either way, the New Jersey Department of Environmental Protection (NJDEP) may view these entities as one facility because of their common control. This article will examine the definition of common control according to the state of New Jersey and the steps that facilities must take to determine whether they potentially share operations.
According to the New Jersey Administrative Code 7:27-8.1, the term facility is defined as “the combination of all structures, buildings, equipment, control apparatus, storage tanks, source operations, and other operations that are located on a single site or on contiguous or adjacent sites and that are under common control of the same person or persons”.

Does Common Control Apply?

In order to determine whether common control is triggered, the facility is required to complete a Common Control Self-declaration form. Within the Common Control Self-declaration form, the following questions must be answered:
  1. Does this facility share common workforces, plant managers, any corporate executive officers, OR any board members with the other facility?
  2. Does this facility share production equipment OR pollution control equipment with the other facility?
  3. If there are any contractual or other arrangements between this facility and the other facility (other than a lease), does the contract or arrangements provide operational control, financial control, exclusive supply and/or exclusive acceptance of all raw material except offsite utilities (gas, water, electric), or expansion decision rights for one party over the other?
  4. Is there any contract or other arrangement with a third party or parties that effectively links this facility and the other facility to a common source of control by the same person or persons?
These questions aim to ensure that the two entities do not employ the same people to operate equipment, manage employees, etc. There should also be no shared contracts or agreements that link the two entities’ operations. Additionally, they aim to validate whether equipment is owned and operated by a single entity. The two entities cannot share any equipment, including but not limited to:
  • storage tanks
  • wastewater treatment
  • loading operations (truck, rail, marine)
  • control devices

How Does Permitting Change?

If the answer to any of the common control self-declaration questions is yes, the operations will be considered to be under common control. In this event, the two entities will either need to apply for a single air permit or modify an existing permit to include affected equipment from both entities’ operations. The air permit should be certified by a single responsible official, or the existing responsible official at that site.
Larger facilities may have collectively greater emissions which may require them to be subject to State and Federal rules and regulations. These types of facilities would need an operating permit (Title V) for major source facilities as opposed to a pre-construction permit for minor facilities. If the combined emissions for the facility exceed any of the following air contaminants (tons per year) thresholds, the facility is considered to be major source.
Table 1.
Contaiment Threshold (tpy)
Carbon Monoxide 100
TSP (Total Suspended Particulate) 100
PM-10 (Particulate Matter ≤ 10 µm) 100
Sulfur Dioxide 100
VOC (Volatile Organic Compounds) 25
NOx 25
Lead 10
Any HAP (Hazardous Air Pollutant) 10
All HAPs Collectively 25
Any Other Air Contaminant, except CO2 100

If the answer to all the common control questions is no, the two operations will be considered separate entities. Each operation will get a separate program interest number and will apply for separate air permits. These air permits should be certified by the responsible official for that specific operation only.

If there is any ambiguity involved regarding the answers to the common control questionnaire, it may be necessary to meet with officials at NJDEP to discuss the facilities’ operations. In this case, it is recommended to prepare a full description of the operations taking place and a map of the site which clearly delineates the two entities’ operations. Ultimately, the decision on whether two entities fall under common control is up to NJDEP. Thus, it is important to provide as much information as possible.
In addition to the four common control questions, the Common Control Self-declaration form requires the responsible official’s signature/date, their title, their telephone number, and their email address. If the facility is at the beginning of the process of applying for a Program Interest ID, they should send the completed form to [email protected] along with their Facility ID Request form. If a permit writer, enforcement officer, or county inspector requested that the facility complete the form, they simply need to return the form to that individual.
Trinity Consultants’ Princeton New Jersey office has previously assisted facilities with their common control determination and will continue to assist facilities with determining common control applicability and applying for an air permit under common control.

Given the regulatory environment, we couldn’t sustain our original way of doing things, which was manually with spreadsheets. Lots of data and inputs – we were hitting a breaking point with spreadsheets and calendar task management. We engaged Trinity to help us be more resilient in the face of regulatory and reporting changes. They helped us calculate emissions and provide timely notifications before and after events.
