What sources make up the Tier 1 categories used in the emissions trends?
Tier 1 categories are assigned by source classification codes (SCCs) that are the most specific processes available in the NEI. The latest SCC list with the Tier 1 assignments can be downloaded from the EPA SCC website in Comma Separate Values (CSV) format.

What is the cause of the large decrease in electric utility emissions, particularly sulfur dioxide, starting in 1995?
SO2 emissions reductions from utilities during this time are primarily attributed to the impacts of the acid rain program. As described on EPA’s Acid Rain Program web page, Phase 1 of this program began in 1995 and affected 263 units at 110 most coal-burning electric utility plants in 21 eastern…

This opportunity does not include Focus Area 1, AOC/Toxics. Many AOC may have underserved community populations. Does EPA have guidelines for how to operate in AOCs without causing duplication interference in that program?
The principal recipient may fund subaward projects within AOCs, provided the primary focus of the project meets the eligibility requirements. EPA will work closely with selected principal recipients as part of our substantial involvement to ensure there is adequate coordination with state and federal AOC programs.

Why do mobile source NOx emissions jump higher between 2001 and 2002 on the emissions trends?
The emissions model used for mobile sources changed from MOBILE6.2 to MOVES 2010 in December 2009. This change included a notable increase in NOx emissions. The EPA adjusted data back to 2002 to reflect the change in models. The higher emissions in 2002 are because of this method change and…

Why do the PM2.5 emissions for the electric utilities source category jump up between 1998 and 1999?
The estimation method for PM emissions from fuel combustion sources was enhanced beginning with the 1999 National Emissions Inventory. Prior to 1999, the emissions measurement data methodology only included the filterable portion (which means the solid particle matter at elevated stack temperatures). Beginning with the 1999 NEI, both the filterable…

If a state does not have any federal or state recognized tribal lands, can PR applicants include outreach projects in similar communities that are not formally recognized? Does the screening need to rely on tools of economic factors?
Applicants do not need to rely solely on EJ Screen or the Climate and Economic Justice Screening Tool to justify inclusion of communities that may not be formal recognized. If applicants can make the case for why these communities are underserved and have needs that could be met through this…
