Point Source Registration

Program overview

The Vermont Air Quality and Climate Division (AQCD) accepts online data submissions and fee payments for the air contaminant registration requirement under Subchapter VIII of the Air Pollution Control Regulations.  Facilities subject to annual registration are notified by email from when the online forms are open for submission.  If you did not receive an email requesting registration data including instructions on accessing ANR Online and believe this was in error, please contact us at

Regulatory deadlines

  • February 1 - Registration submissions due
  • May 15 - Registration fee payment due


Section 555c of Title 10, Chapter 23 and section 2822(j)(B) of Title 3, Chapter 51 require that any person operating or responsible for the operation of an air contaminant source emitting more than five tons of "criteria" air contaminants per year shall register the source annually and pay the designated fees.  In addition, each operator of a source listed in 5-802(2) of the VAPCRs which emits less than five tons of any and all air contaminants per year shall also register the source with the Secretary, and shall renew such registration annually.  The structure of the program is defined in more detail in the Vermont Air Pollution Control Regulations, Subchapter VIII.  A list of Hazardous Air Contaminants (HACs) are found in Appendices B & C of the regulations, and other detailed information pertaining to HACs may be located on  the Hazardous Air Contaminants page.

Since Air Contaminant Registration first became required in 1987, the Air Division has compiled a list of sources in the state subject to the requirement.  The Division attempts to contact any source which is likely to be subject to the registration requirement.  Once a source comes "aboard" and information has been processed for the first year of inclusion into the program, renewal of the registration each year is a relatively simple procedure.

If you need to register a source for the first time, the Air Division will need to organize your initial data submittal into a satisfactory representation of individual processes and stacks for your source (hereinafter referred to as "facility" because more than one source may comprise an overall facility subject to Air Registration).  Please contact Dan Riley (802-272-3695), the administrator of the program, to determine what (if any) information for your facility already is on file and what additional information may be needed.  Information regarding fuel consumption or process materials usage for the most recent calendar year is often required.  After contacting this office you will receive additional guidance.

Annual Registration Process

Since 2021, the annual point source registration for air contaminant emissions has been done through the ANR Online platform.

Registration Data

A relational database is used to house the registration information the State receives and facilitate management of the Registration Program.  This database includes information at the facility, stack, process, and segment level in a manner consistent with EPA National Emissions Inventory databases for ease of transfer of information to the Federal Government.  This level of detail is necessary so the State can make an accurate assessment of actual annual emissions for the calendar year in question.  The data submitted for registration requirements is also utilized by other sections in the Air Division.  Summary annual emissions data of registered point sources can be found in the file download below:
