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…

May I generate RINs that I produced and sold for non-road use in the past so that I can reinstate those RINs under RFS2?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Section 80.1426(c)(2) provides that RINs are assigned to a volume of renewable fuel when ownership of the RIN is transferred along with ownership of the volume of renewable fuel. A comparable provision appear in the RFS1 regulations, at…

Could an organization in the coalition be a Project Subrecipient if there is a conflict-of-interest policy in place?
Full Question If we develop a conflict-of-interest policy and require recusal from evaluating or prioritizing projects where a conflict arises, would this allow EJ orgs to submit projects for funding even if they are getting paid to advise on the structure and process for the re-grant program and participation in…

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.

Is there an expectation on whether small subawards, for ~ $50K, or large subawards, for ~$750K are preferable? For example, a large subaward could be the only thing a regional PR could award if they ask for the minimum of $2,000,000.
The RFA does not state a preference for the size of the subaward, so long as the subaward is within the $50,000 to $750,000 limit. GLNPO will look to applicants to describe the program to be carried out and why this amount of subaward funding makes sense for their specific…

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…
