## Emissions

Most of the air pollution emissions data prepared and used in analysis and tracking for regional haze planning in the WRAP re gion is originally collected and reported in some form by the respective regulatory jurisdictions, i.e., state, local, and tribal a ir pollution control programs. For point, area, on

- road and off

- road mobile emissions, these estimates are supplemented by various topical WRAP Forums using contractor support by applying ex tensive quality assurance techniques and review to assure regionally consistent and comparable historic and projection data a cross the WRAP region. Emissions of windblown dust, forest/range/agricultural fire, fugitive ammonia, and biogenics are prepared us ing contractor support to develop centralized estimates of these emissions, with review by the appropriate regulatory jurisdictions. The WRAP Emission Data Management System (EDMS) acts as a central reposito ry of the various types of emissions data results, with visualization and download capabilities. The EPA also provides the National Emissions In ventory (NEI) website that provides trends

- oriented emission data; much of the data in the NEI for the WRAP region would vary from slightly to substantially different from those in the EDMS. This section of the TSS makes available key summary emissions dat a through enhanced analysis and display tools.



## Emissions Data Analysis Tools

Emissions Review Tool The Emissions Review Tool is under constructio n. Once complete, it will be used to investigate state and county emissions which were used in the air quality model.



### Emissions Viewer This ArcIMS mapping tool provides access to regional emissions and modeling maps. You can zoom, pan, query, print, and add or subt ract layers to the map display.



### E missions Inventory Reports (EDMS) Emissions Inventory Map Tool (EDMS) The Emissions Data Management System (EDMS) is an emission inventory data warehouse that serves as a central regional emissio ns inventory database to facilitate the data collection efforts for regional analysis of air qu ality in the West, including modeling, tracking and data analyses.



## Emissions Methods

Emissions Overview : These methods describe the collection, process ing, and evaluation of monitoring data needed for evaluating regional haze in the WRAP region

. Point Emissions : Describes how the point emissions inventory was developed.

Area Emissions : Describes how the area (including oil and gas) emissio ns inventory was developed.

Mobile Emissions : Describes how the mobile (on

- and off

- road) emissions inventory was developed.

Dust Emissions : Describes how the dust emissions inventory was developed.

Offshore Emissions : Describes how the off shore emissions inventory was developed.

Fire Emissions : Describes how the fire emissions inventory was developed.
Key to Monitoring

- Modeling

- Emissions Mapping : This table summarizes the relationship among real

- world visibility

- related parameters and parameters defined by the IMPROVE program, the CM AQ and CAMx models, and WRAP emissions inventories. Specific topical designations and direct comparisons are presented. ( HTML or Excel ) 

## Emissions Links and Projects

WRAP Emissions Data Management System (EDMS) : An emission inventory data warehouse and web

- based application that provides a consistent approach to regional e missions tracking to meet the requirements for State Implementation Plan (SIP) and Tribal Implementation Plan (TIP) development and periodic review and upd ates.

WRAP Regional Modeling Center (RMC) : The WRAP RMC assists State and Tribal agencies in conducting regional haze analyses over the western U.S. by operating regional s cale, three

- dimensional air quality models that simulate the emission, transformation, and transport of pollutants and the effects on visibility in WRAP Class I Areas.

WRAP Fire Emissions Tracking System (FETS) : The WRAP’s Fire Emissions Tracking System (FETS) is a database with a web interface for planned and unplanned fire events. Th e design of the FETS enables efficient data acquisition, stable data storage and availability, real

- time coordination among smoke m anagers, and cost effective development of fire emission inventories. Reliable and accepted technical methods to estimate fuel consumption and emissions from fire events are implemented in the FETS as are tools to est imate emissions averted due to the appl ication Emission Reduction Techniques. Users can view fire data on

- screen with a mapping tool and query the database for downloads of data into model

- ready formats and CSV or DBF formats.
