TRI search output help

Comparison Chart

If your search retrieves a single TRI facility (or part of a facility) within a single TRI year, then this chart will appear comparing all of the releases and waste from that facility to other TRI facilities in the same year. If your search retrieves more than one facility, but all of the facilities that it retrieves are within a single county within a single TRI year, then this chart will appear comparing all of the releases and waste from that county to other TRI counties in the same year.

The comparison is done by percentages within the set of facilities or counties, with 0% being best and 100% being worst. In other words, if a facility had total releases that were numerically larger than those of 10% of all other TRI facilities, and smaller than those of 90% of all other TRI facilities, it would be marked as 10%. Facilities with the same actual number of pounds of releases or waste have been given the same percentage. Therefore, you should expect that there will be some number of facilities all at 0% (since they all have zero releases or waste) and that the first facility with a non-zero release or waste number will suddenly jump up to 5% or 10%, because it has a higher percentage number than all of the facilities with zero.

Comparisons between counties are done on the same basis as with facilities, except that all of the facilities within the county and year are summed up. Note that even if your search only selects part of a county (for instance, a city or a zip code) the comparison chart will be based on the entire county.

Specific numbers within the comparison chart are as follows: Releases is based on the total pounds of all onsite releases to air, ground and surface water, underground injection, and land. Wastes is based on the total pounds of all waste generation (from Section 8 of the TRI form). Carcinogens, Mutagens, and Teratogens are based on the total pounds of onsite TRI releases of chemicals that the New Jersey Fact Sheets data set classifies as carcinogens, mutagens, or teratogens. Note that a single chemical can be classed as belonging to more than one of these categories.

For more information about RSEI scores, try here.

A special note on the RSEI scores in this section: RSEI scores only make sense when compared to other RSEI scores -- a score of 3 is 3 times of as much concern (if you are concerned about the things that RSEI tries to estimate) as a score of 1. Therefore the summary supplies the score total for the search, but it also supplies, for comparison purposes, the percentage that the search makes up of the total RSEI score for the entire TRI year. If your search is for more than one year, the average percentage (by year) that the search is of the year range indicated is given. The RSEI year range matches the year range of your search except that RSEI data only exists for 1988-2011 for the version of RSEI that RTK NET used.

Totals (for waste transfer reports)

This section gives basic totals for the search -- TRI transfer quantities added up for all of the records that match your search criteria.

Waste released

This section shows a pie chart and table that both provide the same information -- a breakdown of the total releases for the search by category. You can get a more detailed breakdown by clicking on the pie chart or the "Expand" link under the table.

A description of what the various categories and types of releases are is here.

Waste generated

This section shows a pie chart and table that both provide the same information -- a breakdown of the total wastes for the search by category. You can get a more detailed breakdown by clicking on the pie chart or the "Expand" link under the table.

Release trend (releases by year)

This section shows a bar chart of total releases by year. The information is repeated in the table below the waste trend bar chart.

The bar chart and table use "core chemical" searching to eliminate chemicals that were added to TRI, removed from TRI, or changed reporting guidance drastically within TRI during the range of years for your search. That is intended to allow you to see changes from one year to the next that are actual, not those that are caused by TRI reporting changes. This means that if your search itself did not use the "core chemical" search criterion, the total for all the years from the table won't match the total for your search.

Also, non-manufacturing industries were added to TRI in 1998, and these have been kept in the year trends. Therefore, you may see a sudden peak in 1998 because of the addition of these industries.

Waste trend (waste by year)

This section shows a bar chart of total waste by year. The information is repeated in the table below.

The bar chart and table use "core chemical" searching to eliminate chemicals that were added to TRI, removed from TRI, or changed reporting guidance drastically within TRI during the range of years for your search. That is intended to allow you to see changes from one year to the next that are actual, not those that are caused by TRI reporting changes. This means that if your search itself did not use the "core chemical" search criterion, the total for all the years from the table won't match the total for your search.

Wastes were not reported in TRI before 1991, so if your search includes years before that, waste amounts for those years will not be shown.

Also, non-manufacturing industries were added to TRI in 1998, and these have been kept in the year trends. Therefore, you may see a sudden peak in 1998 because of the addition of these industries.

RSEI Score trend (RSEI score by year)

This section shows a bar chart of total RSEI score by year. The information is repeated in the table below.

The bar chart and table use "core chemical" searching to eliminate chemicals that were added to TRI, removed from TRI, or changed reporting guidance drastically within TRI during the range of years for your search. That is intended to allow you to see changes from one year to the next that are actual, not those that are caused by TRI reporting changes. This means that if your search itself did not use the "core chemical" search criterion, the total for all the years from the table won't match the total for your search.

RSEI scores were not calculated for TRI before 1988 or after 2011, so if your search includes years before or after that, scores for those years will not be shown.

Also, non-manufacturing industries were added to TRI in 1998, and these have been kept in the year trends. Therefore, you may see a sudden peak in 1998 because of the addition of these industries.

Parent companies

The parent company of a TRI facility is the ultimate, top-level company that owns the facility. TRI facilities are suposed to report their parent company to EPA along with the rest of their TRI data.

This section shows the top parent companies for your search (those with the greatest poundage of total releases, or total transfers for transfer reports). They have been added up using the exact spelling of the TRI parent company name, so the same parent company may appear many times in the list under slightly different spellings, dividing its total releases up. This is clearly not the ideal way to look at parent companies, and RTK NET plans to experiment with an improved, modified list of parent companies at the next upgrade of the TRI Web search program.

For those facilities that list their parent company as "NA", the facility name has been used as the parent company.

For transfer reports, the parent company is the company whose facilities are sending the transfers, not the company whose facilities are receiving the transfers.

Chemicals by RSEI score

This section shows the top TRI chemicals that contribute the most to the overall RSEI score for the search. For more information on RSEI, try here.

General industries

This section shows the largest industrial categories within the search by total releases (or total transfers for transfer searches). The industrial categories were developed by EPA in order to represent the industries that must report to TRI. They generally group together a number of more detailed industrial classifications that are defined by 6-digit NAICS industry codes.

For a list of all of the TRI general industries, look at the select list for industries in the search form here.

Specific industries

This section shows the largest industries within the search by total releases (or total transfers for transfer searches). The specific industries are defined by 6-digit NAICS industry codes.

For a list of all of the TRI specific industries, look at the select list for industries in the search form here.

Release lbs column

This column shows total releases, including on-site releases to air, water, land, and underground, off-site transfers to disposal, and Form A midpoint release estimates. For more information on all of these, try here.

Waste lbs column

This column shows total waste, including production-related waste recycled, treated, released, or disposed of, non-production-related waste released, and Form A midpoint waste estimates. For more information on all of these, try here.

RSEI Score column

This column shows the RSEI Score, a unitless number that is used to compare TRI releases and transfers on the basis of chronic human health risk. RSEI Scores are estimates, not full risk assessments, but they give some indication that a facility or submission with a score of (for example) 2 may be of twice as much concern for chronic human health effects as one with a score of 1. RSEI Scores do not yet exist for TRI data past 2011. For more information on RSEI Scores and how RTK NET handles them, try here.

What happens to transfers

This section shows a pie chart and table that both provide the same information -- a breakdown of the total transfers for the search by what happens to them at their destination -- their "management type". You can get a more detailed breakdown by clicking on the pie chart or the "Expand" link under the table.

A description of what the various categories and subcategories of transfers are is here.

Transfer trend (transfers by year)

This section shows a bar chart of total transfers by year. The information is repeated in the table below.

The bar chart and table use "core chemical" searching to eliminate chemicals that were added to TRI, removed from TRI, or changed reporting guidance drastically within TRI during the range of years for your search. That is intended to allow you to see changes from one year to the next that are actual, not those that are caused by TRI reporting changes. This means that if your search itself did not use the "core chemical" search criterion, the total for all the years from the table won't match the total for your search.

Also, non-manufacturing industries were added to TRI in 1998, and these have been kept in the year trends. Therefore, you may see a sudden peak in 1998 because of the addition of these industries.

TRI maps and charts help

Releases by state map

This map shows TRI releases for the latest reporting year available, in pounds. Releases are included within a state if they were released by a facility in the state to the air, water, land, or underground, or were transferred to disposal from a facility in the state. In addition, TRI reports on Form A have release amounts assigned to them as the midpoint of their possible release range. For more information on releases, try here.

Wastes by state map

This map shows TRI total wastes for the latest reporting year available, in pounds. The waste amount is the total amount of TRI chemicals that is not part of products, and therefore needs to be dealt with in some way. Reducing the amount of waste generated is generally considered to be the best way of handling waste.

The total waste amount is the total quantity of TRI chemicals recycled onsite, recycled offsite, burned for energy recovery on and offsite, destroyed in treatment on and offsite, and released (whether due to production processes or one-time events) onsite or transferred offsite for disposal. It includes waste amounts assigned to Form A reports as the midpoint of their possible range. For more information on wastes, try here.

Wastes by year bar chart

This bar chart shows TRI total wastes for each year since 1998, in pounds. The waste amount is the total amount of TRI chemicals that is not part of products, and therefore needs to be dealt with in some way. Reducing the amount of waste generated is generally considered to be the best way of handling waste.

The bar chart starts at 1998 rather than 1987, the earliest year of TRI data, because 1998 was the year in which many new industries, such as mining and electricity generation, were added to TRI. Starting with that year makes year-to-year comparisons meaningful without either having a jump up in the year that new industries were added, or having to remove the new industries. The bar chart also uses the "core chemical" set to include only those chemicals that were not added or delisted from TRI during the year range, so that changes from year to year will not be due to changes in TRI reporting requirements. To get more information about year trends, try here.

The total waste amount is the total quantity of TRI chemicals recycled onsite, recycled offsite, burned for energy recovery on and offsite, destroyed in treatment on and offsite, and released (whether due to production processes or one-time events) onsite or transferred offsite for disposal. It includes waste amounts assigned to Form A reports as the midpoint of their possible range. For more information on wastes, try here.

Releases by type pie chart

This pie chart shows TRI releases for the latest year of TRI data available, broken out by "release medium", i.e. whether the releases were to air, water, land, or underground. Transfer offsite to disposal are considered to be a form of release by EPA, since they involve the same activities offsite that would count as releases onsite. The pie charts also includes a category composed of release estimated by taking the midpoints of the possible release ranges of Form A submissions.
