Where can I find older NEI data (prior to 2008)?
The raw data and summaries that are still available (dating back to 1990) can be obtained from the web page https://www.epa.gov/air-emissions-inventories/pollutant-emissions-summary-files-earlier-neis . Starting with 2001 data, a more limited selection of summary files are available.

How do the different parts of particulate matter (PM) fit together?
The various parts of PM in the NEI are related as follows. PM10-FIL > PM25-FIL because PM10-FIL includes PM25-FIL PM25-PRI = PM25-FIL + PM-CON This equation only applies at the process level. Because some sources only can report PM2.5 (due to test method differences), this equation does not apply to…

How does PM2.5 relate to PM species such as EC, OC, SO4, NO3, PMFINE, and DIESEL-PM25?
Primary PM2.5 estimates are speciated into the five PM species in the NEI: elemental (black) carbon (EC), organic carbon (OC), nitrate (NO3), sulfate (SO4), and the remainder of PM25-PRI (PMFINE). Diesel engine PM25-PRI and PM10 emissions are also labeled as DIESEL-PM25 and DIESEL-PM10 for mobile source diesel engines. For all…

While there is no renewable fuel obligation under the RFS2 program for the production or importation of conventional jet fuel, RINs can be generated for renewable jet fuel. Is that right?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . As described in 80.1407, only gasoline and diesel fuels produced or imported into the U.S. are subject to the renewable fuel standards. Thus, only gasoline and diesel fuel volumes produced or imported by an obligated party factor into…

How much flexibility do applicants have in refining the Outcomes and Outcomes over time using an adaptive management approach?
Full Question How much flexibility do applicants have in refining the Outcomes and Outputs identified in their application over time using an adaptive management approach? Answer EPA recognizes that “adaptive management” can be an effective tool in getting the best results. Adjustments to outputs and outcomes based on the adaptive…

Do we have to pair hands-on, place-based Great Lakes enviro education with one of the other GLRI actions/related MOP?
Full Question Do we have to pair hands-on, place-based Great Lakes enviro education (i.e., GLRI Measure of Progress, GLRI MOP 5.1.1 youth impacted through education and stewardship projects) with one of the other GLRI actions/related MOP? Answer Projects that relate to 5.1.1 are not required to connect to another specific…

Should applications include Outputs and Outcomes related to Project Subrecipient evaluation criteria?
EPA cannot provide a recommendation on this question. Applicants must decide whether or not they develop outputs and outcomes based on Project Subrecipient evaluation criteria for themselves. Please see section I.F. for information on Outcomes, Outputs, and Performance Metrics which includes information on performance measurement and evaluation plans.

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…

Is it better to not include letters of support from orgs given that they will ultimately be subject to have to apply in a competitive process?
Full Question: The RFA mentions that contractors and subawards must be awarded competitively, however in our niche field and in many of these underserved communities (especially in less urban environments) there may only be 1 or 2 sub-awardees/contractors to work with at all. Should we apply with support listed from…
