Overview

MARAMA is coordinating the development of regional emissions inventories for air quality modeling. The inventory includes emissions from Connecticut, Delaware, the District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Virginia.

The emissions inventories are being developed for the following sectors: point sources, stationary area sources, on-road mobile sources, and non-road mobile sources. NIF Inventories will be developed for 2007, 2013, 2017, and 2020.  ORL files are being developed for 2007, 2017, and 2020. The following document describes the process for developing the inventory.

•  Work Plan for Emissions Inventory Development

The links below provide data and documentation for the inventory that have been developed so far. The project is expected to continue in 2011.

Final NIF and ORL formated inventories are posted here:
