Western u.s. regional analysis – 2014 neiv2 emissions inventory review for regional haze modeling electricity outage


OverviewFor western U.S. regional analysis using photochemical modeling for Regional Haze, WESTAR-WRAP is assisting state air agencies in their review of the 2014v2 NEI. yoga gas relief pose The process will allow participants to review and provide updates to these inventories. Feedback and revisions to the inventories may be incorporated into air quality modeling by the WRAP for regional photochemical modeling.

The Regional Haze Planning Work Group for Emission Inventories and Modeling Protocol (RHPWG EI & MP) Subcommittee held four conference calls from July – September, 2018. The Subcommittee solicited comments from state and local air agencies in the WRAP region on EPA’s 2014 NEIv2. The Work Group focused on pollutants and emissions sectors that had the potential to influence photochemical modeling for Regional Haze Planning, such as large PM sources and major point sources. Outcomes from the WG are listed below. WG meeting notes, an outline of the review process, and comments from participating agencies follow the WG summary.

ProcessThe initial review step for EPA’s 2014v2 NEI following a three phase process is described in this May 22, 2018 memo. The initial review aspects listed in the memo can be evaluated using 3 data review options below. u gas station near me Option 1 is a high level review will look at tabular state and county inventories for key pollutants. Option 2 will enable a more detailed review to examine additional inventory parameters, such as individual point sources. gas and bloating pain Option 3 will allow review of a map-based emissions inventory review tool provided by the IWDW. Additional description and materials for the review process are provided below. Subsequent memoranda for additional review of 2014NEIv2 and other base and projection inventories will be added over time.

Data for individual point sources for 16 pollutants from EPA’s 2014v2 modeling platform. The point data are for non-fire inputs, e.g. pt_oilgas, ptegu, ptnonipm (and cmv_c3 for California, Oregon and Washington). The Excel spreadsheets contain parameters such as annual emissions, facility name and ID, and stack parameters where applicable.

Emissions review tool for EPA’s 2014 NEIv2 (data originate from EPA’s "allsector" county and tribal level inventories). Note: these are the same data as were used in the spreadsheets in Option 1, above, although they include the entire US rather than just WRAP states. The NEI data are shown as tabular data, state and county maps, and pollutant and emissions sector pie charts.

I wanted to give some clarification regarding the NEI Sector Summary data that was sent out previously. a gas station near me The way that EPA separates this information is not immediately intuitive. This is because the sector summary is aggregated by SCC, not NAICS code. The SCC table that EPA provides has each SCC matched to an EI sector which is the basis for the sector summary.

• Now available! *2014 National Emissions Inventory (NEI) Report* This new highly visual and interactive Report shows graphs, tables, and maps that summarize national and state emission trends and emission profiles for states and counties based on the 2014 NEI v2 data. electricity merit badge worksheet With this tool, users can explore the emissions data and answer basic questions they have about the NEI and emission trends by looking at what the data shows for national, state, and local areas. The Report distills a considerable amount of data detail inherent to the NEI and provides emission summaries for the criteria pollutants, black carbon, and 5 select HAPs. It is not a query tool for accessing all details of the entire 2014 NEI data. NEI data access query tools and detailed data files remain available on the EPA NEI program website. Please explore the 2014 NEI Report and bookmark it on https://gispub.epa.gov/neireport/2014/. gas apple pay The Report is also posted on the NEI program website https://www.epa.gov/air-emissions-inventories.
