The Toxics Release Inventory (TRI) Program has found that data users are most interested in the quantity data reported by TRI facilities, including the quantities of toxic chemicals released on-site, the quantities transferred off-site and summary data concerning releases, recycling, energy recovery and treatment as they appear in the Pollution Prevention portion of the TRI Reporting Form R (one of the two reporting forms EPA uses to collect TRI data from facilities). The TRI Basic Data Files were created in response to feedback from users requesting the state and national datasets. In the past, users would frequently contact the TRI Program to request all of the TRI data. Typically, however, users were primarily interested in the quantity information found in TRI, such as on-site releases or off-site transfers. Users also wanted these data elements for all TRI reporting years, and indicated that all of this information wasn't easily available in the online TRI query tools. The TRI Program developed the TRI Basic Data Files to provide easier access to TRI data. This document defines and describes the data file format of these files. It lists the record layout and specifically defines each field in that layout. Finally, it gives users instructions on how to load these data files into two common desktop products, Microsoft (MS) Excel and Access. Please note that this file format does not contain data from non-quantitative areas of the Form R or Form A, such as "Chemical Activities and Uses", "Treatment Methods and Efficiency", "Recycling Processes" and "Energy Recover Processes." To see the data from these and other non-quantitative sections of the Form R and A, refer to the "TRI Basic Plus Data Files." File Format Information The general categories that users are interested in and that are represented in this file are as follows: • Facility Name, Address, Latitude & Longitude Coordinates, and SIC or NAICS codes • Chemical identification and classification information • On-site Release quantities • Publicly Owned Treatment Works (POTW) transfer quantities • Off-site Transfer quantities for release/disposal and further waste management • Summary Pollution Prevention quantities (Section 8 of the Form R) The file contains approximately 100 data fields. The data is simple ASCII text that is comma-delimited. This format loads easily into many desktop products such as spreadsheets and database software. The record layout for the file appears in the next section. There are seven columns in the layout format. The first column (identified by the column heading '#') is a sequential field number identifier. The second column, "Field" is the name of the data field as it will appear in the data file. Many of the field names begin with a section reference, such as "5.1 - Fugitive Air". The "5 .1" represents the section of the Form R where the data came from. Many users find the data fields easier to use when they are prefaced with the section number. 3 ------- The third and fourth columns, "Maximum Length" and "Data Type", specify the maximum length and the data type of the field. The "Maximum Length" column also indicates the format of numeric data. Comma notation is used for numbers that may contain decimals. For example, a "Maximum Length" value of "22,7" indicates that the number can be 22 digits long with 7 digits to the right of the decimal point. There are two possible values for the "Data Type". They are 'C' for Character/Text data and 'N' for numeric data. The fifth and sixth columns under the "Form R Reference" heading indicate the "Part" and "Section" of the Form R or A where the data originates from. Refer to the "Toxic Chemical Release Reporting Forms and Instructions" at http://www.epa.gov/tri/report/index.htm for more information on the Form R and Form A for additional information on each data field in this file. The "Definition" column gives a description of each data element and provides notes about its origin and use. There are several data fields that represent totals in the data file. The "Definition" column tells which data fields are added together to obtain the totals. 4 ------- File Content Types There are three different types of TRI Basic Data Files. The first type, known as the "State Data File", will only contain data for one state, district or US territory for each reporting year. For instance, one "State File" might be all the data for the state of Alabama for reporting year 2010. The second type, known as the "National Data File", will contain all the TRI data for the United States. This includes data for all 50 states and the six US districts and territories (i.e. American Samoa, District of Columbia, Guam, Northern Mariana Islands, Puerto Rico and the Virgin Islands). The third type, known as the "Federal Facility Data File", will contain data for all government owned and operated federal sites. Each file type will have a slightly different naming convention. However, all file names will follow this standard pattern: File Name = "TRI" + Reporting Year + File Content Where the text string "TRI" identifies the file as TRI data. The "Reporting Year" indicates which reporting the file represents. The "File Content" will indicate which of the three file types (Federal Facility, National or 56 States) the file is. It will be either... Here are some examples and explanations of each file type: State File: TRI2010_AL. csv The file name above, "TRI_2010_AL.csv" is a "State File" type. It contains the facility and chemical identification as well as quantity data for all chemicals reported by facilities in Alabama (AL) for reporting year 2010. File Naming Conventions and Version Numbers • A State Abbreviation • The word "US" • The word "FED" ... for a State Data File ... for a National Data File ... for a Federal Facility Data File National File: TRI 2000 US.csv 5 ------- The file name above, "TRI_2000_US.csv" is a "National File" type. It contains the facility and chemical identification as well as quantity data for all chemicals reported by all facilities in reporting year 2010 Federal Facility File: TRI_2005_FED.csv The file name above, "TRI_2005_FED.csv" is a "Federal Facility File" type. It contains the facility and chemical identification as well as quantity data for all chemicals reported by All Federal Facilities in reporting year 2005. File Usage - Limiting Factors Appendices B and C describe the steps for loading the TRIBasic Data Files into Microsoft Excel and Access respectively. Note that for versions of Microsoft Excel prior to and including Version 2003 (found in Microsoft Office 2003) there is a limitation of 65,535 rows that can be loaded into a worksheet. Because of this limitation, users will not be able to load the "National Files" containing 85,000 or more records into these versions of Excel. However, the limit on the 2010 version of Excel is 1,048,576. So, users of that version of Excel will be able to load the National Files as well as the other two file types without a problem. Microsoft Access, a desktop database tool, does not have a limit on the number of records that can be loaded into a table. Check the limitations of any other tool to be sure that the TRI Basic Data Files can be loaded in full. Zeroes in the Data The TRI Basic Data Files were created to be loaded into different tools such as spreadsheets, databases and statistical applications. Some of those tools require that numeric data be populated with a number (and not a blank) in order for the tool to work correctly. For instance, to total a column in many spreadsheet applications, all rows in that column must contain a number and not be blank. In light of this, zeroes have been input into the TRI Basic Data Files in places where numeric data was blank. There are three instances where this normally occurs. First, facilities can file either a Form R or a Form A when reporting to TRI. The Form A is a short form that is used when chemical releases and other waste management quantities are below certain thresholds. It only requires that facility enter its identifying information and the identity of the chemical it is releasing or otherwise managing as waste. It does not require the facility to enter any actual quantity data. For chemicals submitted on the Form A, all the quantity data is represented as zeroes. See the TRI Reporting Forms and Instructions at http://www.epa.gov/tri/report/index.htm for more information on the Form A and reporting thresholds. 6 ------- The second case where zeroes have been substituted for blanks occurs when facilities report "NA" or "Not Applicable" for a quantity on the Form R. Reporting "NA" means that the release or waste management quantity is not possible for that facility. For example, if a facility is not located near a water body, it will not have the ability to release any of the chemical to water. Therefore, in section 5.3 of the form R where facilities are asked to enter their on-site water releases, the facility would enter "NA" because the release is not possible. The TRI Reporting Forms and Instructions contain more information on the use of NA in TRI reporting. The third case where zeroes have been substituted for blanks occurs when facilities do not respond to quantity questions on the form R and leave them blank. This occurs most often with the submission of paper forms. Data submitted via the electronic TRI reporting applications (i.e., TRI-ME desktop and TRI-MEweb) do not allow for blanks in quantity data reporting. They require the submitter to enter a number or indicate "NA". 7 ------- Other Online Methods for Accessing TRI Data In addition to downloadable data files, users can also access and query TRI data via multiple online tools and applications, including TRI Explorer, Envirofacts, and TRI.NET. These can be found at http://www.epa.gov/tri/tridata/index. 8 ------- Record Layout Field Documentation for the "Basic Data" File Form R Reference # Field Maximum Length Data Type Part Section Definition 1 Year 4 C I 1 The Reporting Year - Year the chemical was released or waste managed 2 TRI Facility ID 15 C I 4.1 The TRI Facility Identification Number assigned by EPA/TRI 3 Facility Name 62 c I 4.1 Facility Name 4 Street Address 62 c I 4.1 Street Address where facility is located 5 City 28 c I 4.1 City Name where facility is located 6 County 25 c I 4.1 County Name where facility is located 7 ST 2 c I 4.1 State Abbreviation where the facility is located 8 ZIP 9 c I 4.1 ZIP code where facility is located.

To obtain total Surface Impoundment for any year, add fields 41, 42 and 43 together. 44 5.5.4 - Other Disposal 22,7 N II 5.5.4 On-site Other Disposal Releases 45 On-site Release Total 22,7 N II Total Releases On-site for a chemical at a facility. This is a summation of all releases in section 5 (fields 33 through 44). 46 6.1 - POTW- Metals and Metal Compounds 22,7 N II 6.1 If a chemical is a metal (or metal compound) the amount of transfer to a POTW will appear under this data element. Metals and Metal Compounds can not be treated by most POTWs. Therefore, when a metal is transferred to a POTW, TRI considers it an Off-site Release. It will be added to the Off-site Release total. 47 6.1 - POTW - Non- Metals 22,7 N II 6.1 If a chemical is not a metal, its POTW release amount is listed here. This amount will not be added toward the off-site release total. 48 6.1 - POTW-Total Transfers 22,7 N II 6.1 This amount is the total transfers to a POTW of a chemical. This amount will match either 6.1 POTW - Metals and Metal Compounds or 6.1 POTW - Non- Metals 49 6.2- M10 22,7 N II 6.2 Off-site Storage 50 6.2- M41 22,7 N II 6.2 Off-site Solidification/Stabilization for Metals and Metal Compounds Only 11 ------- Field Documentation for the "Basic Data" File Form R # Field Maximum Length Data Type Part Section Definition 51 6.2 - M62 22,7 N II 6.2 Off-site Wastewater Treatment (Excluding POTWs) for Metals and Metal Compounds Only 52 6.2- M71 22,7 N II 6.2 Off-site Underground Injection.
