Homepage » Lesson 7 » Lesson 7.3
So, now you can see where all the sources are on the map, but what are they and how much and what kind of pollution do they produce? There are several ways to see more detail on the data. The first way we'll introduce is to look at the data in the outline view, which is accessed through the Outline button on the main toolbar.
The outline view shows the most detail about the data contained in TEISS for each source. It works like Windows Explorer in that clicking on the (+) sign next to a folder or item will open subfolders showing more detailed data beneath it. If you open the Point Locations folder, you will see the list of counties that you imported data for. Opening the Point Location folder for each county, you will see another folder called Facilities with a number in parentheses next to it. That number tells you how many point sources are in that county, by opening the Facilities folder, you will see a list of the facility names.
To get more information on a facility, click on the name and view the subfolders below it by clicking on the (+) sign next to it. When you click on the name, you will see that the part of the window to the right gives more information, arranged in several tabs about that facility. Within each point source facility, you will keep opening lower levels of subfolders until you get to a folder titled Emissions. Within that folder you will see what pollutants are emitted by that source and how much are emitted.
Point Location - This folder contains all the inventoried point sources in a given location, such as a county or reservation. If you enter point sources into your TEISS project that are located on your reservation, you will create a new Point Location folder for your reservation. Adding reservation point sources will be covered in Lesson 8's Case Project 1.
Facilities - This folder contains the list of facilities that are located in the location designated by the Point Location folder above. By clicking on each facility name, you can view information about the facility in the window to the right.
Release Points - This folder contains a list of release points at the facility it is under. There may be just one release point, a single stack or fugitive emissions from the facility. Some facilities have many release points. By clicking each release point, you will see information on the latitude/longitude or UTM location and how the location was determined on the right-hand side of the window.
Emission Unit - This folder contains descriptions of different operational units within a facility that are releasing emissions. By clicking on each emission unit, you will see more information on it on the right-hand side of the window.
Design Capacities - This folder contains descriptions of design capacities for the emission unit it is under. This folder often contains no information for NEI data downloaded from EPA, because it is not required for the NEI.
Processes - This folder shows detail on what activities and processes are going on at the facility, in the emission unit it is under, that are releasing air pollution. By clicking on each process, you will see more information on the process description on the right-hand side of the window.
Control Equipment - This folder contains information on what, if any, air pollution control equipment is installed on the process it is under. By clicking on each control equipment (if they are present), you will see more information on what kind of control equipment is in use and what pollutants it controls on the right-hand side of the window.
Emission Periods - This folder contains information on the time period during which the process is emitting pollution. Does it emit all year or just during some months of the year?
Emissions - Finally! This folder contains information on what pollutants are emitted by the process it is under. By clicking on each pollutant, you can see how much of it is emitted. |
Area Location - This folder contains all the inventoried area sources in a given location, such as a county or reservation. If you enter area sources into your TEISS project located on your reservation, you will create a new Area Location folder for your reservation. Adding reservation area sources will be covered in Lesson 8's Case Project 1.
Area Process - This folder contains the activities or processes that are included in the area source inventory. Because area sources are usually spread over a large area, you do not need to specify a facility or emission unit for them. Area sources have to be assigned either to a reservation or a county. Examples of area "processes" listed in this folder are:
- Residential wood-burning stoves
- Unpaved Road Dust
- Gas stations
By clicking on each process, you will see more information on the process description on the right-hand side of the window.
Area Control Equipment - This folder contains information on what, if any, air pollution control equipment is installed on the process it is under. By clicking on each control equipment (if they are present), you will see more information on what kind of control equipment is in use and what pollutants it controls on the right-hand side of the window.
Area Emission Periods - This folder contains information on the time period during which the process is emitting pollution. Does it emit all year or just during some months of the year? Most inventories report on an annual basis.
Area Emissions - This folder contains information on what pollutants are emitted by the process it is under. By clicking on each pollutant, you can see how much of it is emitted. |
Non-Road Location - This folder contains all the inventoried non-road sources in a given location, such as a county or reservation. If you enter non-road sources into your TEISS project located on your reservation, you will create a new Non-Road Location folder for your reservation. Adding reservation non-road sources will be covered in Lesson 8's Case Project 1.
Non-Road Process - This folder contains the activities or processes that are included in the non-road source inventory. For non-road sources, each process is a vehicle type-fuel combination. For example:
- Pleasure boat-diesel
- Pleasure boat-gasoline
- Bulldozer- diesel
- All Terrain Vehicle (ATV) - 4-stroke gasoline
- ATV - 2-stroke gasoline
By clicking on each process, you will see more information on the process description on the right-hand side of the window.
Non-Road Control Equipment - This folder contains information on what, if any, air pollution control equipment is installed on the process it is under. By clicking on each control equipment (if they are present), you will see more information on what kind of control equipment is in use and what pollutants it controls on the right-hand side of the window.
Non-Road Emission Periods - This folder contains information on the time period during which the process is emitting pollution. Does it emit all year or just during some months of the year? Most inventories report on an annual basis.
Non-Road Emissions - This folder contains information on what pollutants are emitted by the process it is under. By clicking on each pollutant, you can see how much of it is emitted. |
On-Road Location - This folder contains all the inventoried on-road sources in a given location, such as a county or reservation. If you enter on-road sources into your TEISS project located on your reservation, you will create a new On-Road Location folder for your reservation. Adding reservation On-road sources will be covered in Lesson 8's Case Project 1.
On-Road SCC codes (Process) - This folder contains the activities or processes that are included in the On-road source inventory. For On-road sources, each process is a vehicle type-fuel type-road type combination. For example:
- Light duty gasoline vehicle - interstate highway
- Light duty gasoline vehicle - rural highway
- Light duty gasoline truck - local road
- Heavy duty diesel vehicle - interstate highway
By clicking on each process SCC code, you will see more information on the process description on the right-hand side of the window.
On-Road Emission Periods - This folder contains information on the time period during which the process is emitting pollution. Does it emit all year or just during some months of the year? Most inventories report on an annual basis.
On-Road Emissions - This folder contains information on what pollutants are emitted by the process it is under. By clicking on each pollutant, you can see how much of it is emitted. |
 TURN IN: Using the data you imported from the NEI for your project, make a list of 2 point sources (if present in your area) and 3 area sources included in the NEI files for the counties around your reservation. For each source list the amount of one pollutant emitted by one of the processes. For each of the 2 point sources, write a description of what processes at that facility are releasing pollution.
