How to Use the Query Tool
There are five different querying methods for obtaining Priority Chemical (PC) quantities:
(1) Specific chemical query
(2) Specific states or territory query
(3) Specific EPA region query
(4) Standard Industrial Classification (SIC) query
(5) Combines the first three options
Method 1:
Request information for a specific chemical or a group of chemicals
Users can choose to have a summary table with all PC quantities summed across all states and facilities for a specific chemical. They can also choose to have the information displayed by facility for the same specified chemical. Additionally, users can select multiple chemicals by pressing the "shift" key and clicking at all chemicals they want to get information on. Priority Chemical quantities will be summed up for these chemicals in both the summary table and the facility-specific table.
Request information for a specific state/territory or a group of states/territories
Users can choose to query the database to get PC quantities summed across all chemicals and facilities for a specific state or territory. They can also choose to have the information displayed by facility for the same specified state or territory. Additionally, users can select multiple states and territories by pressing the "shift" key and clicking at all states and territories they want to get information on. Priority Chemical quantities will be summed up for these states and territories in both the summary table and the facility-specific table. Users can also choose to query PC quantities for a specific county or counties per state or terri
Method 3:Request information for a specific EPA region or a group of EPA regions
Users can choose to query the database to get PC quantities summed across all chemicals and facilities for a specific EPA Region. They can also choose to have the information displayed by facility for the same specified region. Additionally, users can select multiple regions by pressing the "shift" key and clicking at all regions they want to get information on. Priority Chemical quantities will be summed up for these regions in both the summary table and the facility-specific table. Method 4:
Request information for a specific Standard Industrial Classification (SIC)
or a group of SICs Users can choose to query the database to get PC quantities summed across all chemicals and states for a specific SIC. They can also choose to have the information displayed by facility for the same specified SIC. Additionally, users can select multiple SICs by pressing the "shift" key and clicking at all SICs they want to get information on to query. Priority Chemical quantities will be summed up for these SICs in both the summary table and the facility-specific table. NOTE: Not all SIC codes are required to report to TRI, therefore, some queries may result in no data (NA). Method 5:
Request information for a specific Chemical, State and Standard Industrial Classification (SIC)
Finally, users can choose to query the database to get PC quantities for a specific chemical, state or territory and SIC. They can also choose to have the information displayed by facility for the same specified group of parameters. For these options users cannot select multiple rows within a combo box.
