Emission Inventory Submittal

2020 Emission Inventory

The NM Environment Department – Air Quality Bureau (Bureau) is conducting a Major and Minor Source Emissions Inventory, excluding facilities in Bernalillo County and on Tribal Lands, for calendar year 2020 (per NMAC).

This inventory will apply to all sources with air quality construction permits (20.2.72 NMAC or 20.2.74 NMAC) or operating permits (20.2.70 NMAC), including General Construction Permits (GCP).  It will also apply to sources with Notices of Intent (NOI) ( NMAC).

Actual emissions from calendar year 2020 can be reported to the Bureau starting January 1, 2021 and are due by 11:59PM on April 1, 2021. Actual emissions are required to be submitted using the online reporting tool, AEIR, provided by the Bureau.

Greenhouse gas (GHG) emissions are required to be reported to the Bureau if the parent company is reporting these emissions to the EPA. However, all businesses with air quality permits are encouraged to submit GHG emissions data.

Emission inventory may be submitted by entering information directly into AEIR or by uploading a specially formatted XML file. An MS Access program that imports and exports this type of file and also calculates emissions of equipment is available for testing at
