Who must report?
A facility must report emissions of hazardous air pollutants when any
of the following occur:
- the facility emits to the air any hazardous air pollutant at or
above the threshold listed in 06-096 Chapter 137, Appendix A;
- where actual emissions are not known, the facility either uses,
processes, or manufactures any hazardous air pollutant at or above
the threshold listed 06-096 Chapter 137, Appendix A;
- the facility releases to a municipal sewer system (POTW) any hazardous
air pollutant that has a vapor pressure greater than 0.1 mm Hg at
or above the threshold listed 06-096 Chapter 137, Appendix A; or
- in the aggregate, a facility emits to the air or releases
to a municipal sewer system any hazardous air pollutant at or above
the threshold listed 06-096 Chapter 137, Appendix A.
A list of hazardous air pollutants and their
reporting thresholds from Appendix A is available here.

When do I have to report?
Hazardous air pollutant emissions are inventoried every three (3) years. The
most recent reporting year was 2005, with all reports
due by July 1 , 2006. The next reporting year
will by 2008, with all reports due by July 1, 2009.

What information must be included?
The Department will no longer be providing reporting forms for
facilities. If you are using paper forms or are a
first time reporting facility, editable Adobe PDF versions of both
forms are available.
The first form identifies the facility and is labeled Facility
Identification Form. Please complete this form as
fully as possible.
The second form contains chemical specific information; it is labeled Emissions
Report. Facilities should list each chemical and may
copy this form as needed.
It is important that you copy the NEDSID # from the Facility
Identification Form to the space provided at the upper left hand
corner of each Emissions Report you need to use for reporting. If
you do not know your NEDSID, please contact Rich Greves at (207)287-7030
or by e-mail at rich.greves@maine.gov.
The form parallels the Toxic Release Inventory (TRI) Form R. However,
Maine's hazardous air pollutant emissions reporting thresholds are lower
than the TRI thresholds under U.S. EPA's Emergency Planning and Community
Right-to-Know Program (EPCRA). If you've determined that your facility
is not required to file Form R, you may still be required to file hazardous
air pollutant emission data with the DEP. For more information
about the Toxic Release Inventory and U.S. EPA's EPCRA Program, visit http://www.epa.gov/tri/.

How should emissions be calculated?
Emissions can be calculated in one of the following ways and should
be reported using a Basis of Estimate code. Write in
the appropriate code.
| Basis of Estimate Code |
Code Description |
| 1 |
Source Test; Stack Test; Monitoring |
| 2 |
Material Balance; Mass Balance |
| 3 |
Calculated Using an AP-42 Emission Factor |
| 4 |
Best Guess |
| 5 |
Calculated Using Another Emission Factor (NCASI, etc.) |
If you do not have the expertise to calculate the emissions for your
facility, tell us the amount of that particular chemical that you
use. Be
sure to include a copy of the Material Safety Data Sheet (MSDS) with
your emissions report.

Where can I find
my latitude and longitude or UTM coordinates?
The coordinates can be found on United States Geological Survey maps
and are available for a small fee from the Maine Geological Survey (http://www.maine.gov/doc/nrimc/pubedinf/pubs/pltopo.htm).
