1. The National Emissions Inventory (NEI) Sally Dombrowski EPA-OAQPS

2. What is the NEI? EPA’s compilation of estimates of air pollutants discharged on an annual basis and their sources. Compilation includes emission estimates submitted by tribal, state, and local air pollution control agencies Estimates calculated by EPA, and emissions obtained from other sources 2

3. EIS and the NEI Emissions Inventory System (EIS) Data repository for air emissions data used to create NEI Contains state, local, tribal and EPA-submitted data Can be multiple emissions values for the same unit/process Annual, monthly, daily data Data available via password-protected web site EIS Gateway https://eis.epa.gov/eis-system- web/welcome.htmlhttps://eis.epa.gov/eis-system- web/welcome.html 3

4. EIS and the NEI (cont.) National Emissions Inventory (NEI) Snapshot in time from EIS Inventory version shared with the public One emissions value per process selected Annual emissions values 4

5. How is the NEI created? Your data has priority in our selection Only one file format is permitted: xml Data must pass QA prior to being submitted to EPA Only incorrect data is rejected; all remaining records accepted Availability to have multiple values and do several types of NEI selections Version done in 6 months or less 5

6. Who Has Access to the NEI? Tribal, state and local agency users of EIS Gateway have access to their data and any National public releases States may authorize tribes READ-access-only to their data This allows you to download data for direct import into TEISS General public has no access to data until data released to public website 6

7. Uses of the NEI NEI is one of key inputs for Modeling of national rules – NAAQS reviews, CSAPR, etc Non-attainment designations NATA Review – toxics risk modeling Trends reports and analyses 7

8. National Emissions Inventory (NEI) Created from S/L/T submitted data to Emissions Inventory System (EIS) General Public Release (GPR) Separate Public Website 8

10. Air Emissions Reporting Requirements (AERR) Rule

11. Reporting Requirement Air Emissions Reporting Rule (AERR) http://www.epa.gov/ttn/chief/aerr/ http://www.epa.gov/ttn/chief/aerr/ Complete criteria pollutant inventory every 3 years All point sources (100 tpy potential to emit threshold) Nonpoint sources Onroad and Nonroad sources Events (wildfires and prescribed fires) 2011 emissions due 12/31/2012; EIS window opens 6/1/2012 11

12. Reporting Requirement (cont.) Annual reporting for type A point source facilities SO2, NOx, CO with potential to emit > 2,500 tpy VOC, PM, NH 3 with potential to emit > 250 tpy Pb with potential to emit > 5 tpy (to be amended to agree with Lead NAAQS level of > 0.5 tpy) HAPs submitted voluntarily by many S/L/Ts, encouraged as part of an integrated report 12

14. Reporting Changes in AERR 40 CFR 70 definition of major source now used for point source reporting Potential to emit, not actual AERR requires emission reports within 12 months from end of inventory No biogenic emissions requirement 14

15. Reporting Changes in AERR (cont.) Model inputs in lieu of emissions are preferred Summer day emissions of VOC and NOx for ozone nonattainment areas only Winter work weekday emissions of CO required for nonattainment areas and areas with maintenance plans 15

16. Reporting Changes in AERR (cont.) Particulate Matter Reporting of PM primary (sum of filterable and condensible components) required under CERR Reporting of filterable and condensible components is a new requirement in AERR We added component-reporting requirement to help us understand what was being reported as PM primary New QA check Report PM 2.5 ; must report PM 10 16

17. What are the Reporting Cycles? Every-Year Cycle Reporting Annual emissions from Type A (large) point sources. If one pollutant qualifies source as Type A, all pollutants must be reported Ozone season and summer day emissions of NOx from sources controlled to meet TIP Call requirements 17

18. What are the Reporting Cycles? Three-Year Cycle Reporting Annual emissions of criteria pollutants from all sources Ozone season and summer day emissions of NOx from all sources Summer day emissions of NOx and VOC for ozone nonattainment areas Winter work week day emissions of CO for nonattainment areas and attainment areas with maintenance plans 18

19. Which pollutants need to be reported? Tribes should report emissions of the following pollutants Volatile Organic Compounds (VOC) PM 2.5 (Filterable, Condensable and Primary) PM 10 (Filterable, Condensable and Primary) Nitrogen Oxides (NO x ) Carbon Monoxide (CO) Lead ( 7439921) 7439921 Sulfur Dioxide (SO 2 ) Ammonia (NH 3 ) 19

20. Will point source reporting for lead be changed ? Lead NAAQS final rulemaking promulgated on October 15, 2008; changed Lead emission inventory point source threshold from 5 tons/year to 0.5 tons/year We intend to revise 5 tons/year threshold for Lead point sources in AERR to help identify potential for Lead point-source problems in attainment/unclassifiable areas under Lead NAAQS 20

21. What About HAPs and GHGs? Hazardous Air Pollutants (HAPs) reporting not required, but we encourage tribes to submit them on voluntary basis using requirements of AERR Greenhouse Gases (GHGs) reporting not required under AERR GHG pollutants accepted in EIS 21

23. 23 Overview of the Tribal New Source Review (NSR) Rule

24. New Source Review Final effective August 30, 2011 Establishes cost-effective preconstruction permitting program for New or modified minor sources Minor modifications at major sources New major sources or major modifications in nonattainment areas Permitting mechanism for major sources to limit emissions to become synthetic minors* Allowing administration of program by tribes through delegation to EPA 24

25. Major NSR Rule New major sources Based on source’s PTE Nonattainment areas – 100 tpy of any pollutant Attainment areas – 100 or 250 tpy depending on source type Modifications to existing major sources Physical change in or change in method Increase in net emissions resulting from change must be significant 25

26. Minor NSR Rule Applies to New and modified minor sources Minor modifications at major sources Must obtain permit prior to construction Minor sources with potential to emit (PTE) equal to or greater than minor NSR thresholds Modifications at minor sources with allowable emissions increase equal to or greater than minor NSR thresholds 26

27. Major/Minor NSR Rule At discretion of reviewing authority Must install and operate control technology Required to submit air quality impact analyses as part of permit applications Assess impacts on national parks & wilderness areas Allow for opportunities for public involvement 27
