Instructions for Submitting Data Corrections

Introduction
EPA seeks comments on hazardous air pollutant (HAP) emissions and other model input data that we used to assess risks from selected industrial major source categories, as required by section 112(f) of the Clean Air Act. The source of this information is the most recent version of the 2005 National Emissions Inventory (2005 NEI), updated with data collected by EPA's Office of Air Quality Planning and Standards. For more information about the 2005 National Emissions Inventory (NEI), please go to:  http://www.epa.gov/ttn/chief/net/2005inventory.html. 

The Microsoft Access file  will enable you to review and suggest revisions to HAP emissions and other descriptive information associated with all facilities in a single Maximum Achievable Control Technology (MACT) category. Instructions for using this file to review the data, revise the data, and submit revisions to EPA are outlined below. Section 6 lists specific steps for submitting your final changes to the EPA. Section 7 of this document defines important terms (e.g., MACT, SIC, SCC, etc.) and all data elements found in this file. The complete outline for this document is listed below:

1.	Application Overview
When this Microsoft Access file opens you are presented with a "Main Page" containing five buttons:
      1. View Summary Data
      2. Revise Data
      3. Review Revisions
      4. Submit Revisions
      5.   Exit Database
After reading these instructions, you should select the "View Summary Data" button to view summary data before making revisions or adding any facilities to this file. After reviewing the current data for your MACT category, you can proceed to the "Revise Data" forms. After making corrections to this file, you should review your corrections and then submit your revisions to EPA as outlined on the "Submit Revisions" form.

2.	View Summary Data
After selecting and clicking the "View Summary Data" button, the form displays national level summary data for all pollutants associated with the MACT category of interest. You can sort the columns in ascending or descending order if you wish to see the highest or lowest emissions and/or if you want to sort by pollutant name alphabetically. This form also provides buttons that allow you to change the aggregation level ("Options") of the data and/or filter by pollutant ("Filter Data").

      a.	Options  -  These buttons allow you to view summary data at varying levels of detail. When you click these buttons, new forms open with data level and filter buttons appropriate to the dataset displayed. These buttons and their accompanying forms are as follows:

               i. MACT HAP Emissions (View National Data Form)  -  Discussed above, this form displays national level summary data for all pollutants associated with the MACT category of interest. This is the default form that opens when you select "View Summary Data" on the "Main Page."

               ii. State County MACT Emissions (View State, County, MACT, HAP, and Emissions Data Form)  -  All emissions for the MACT category are shown at the county  -  pollutant level. This form would allow you, for example, to find your county and view total emissions by pollutant from the MACT category. After viewing emissions at the county level, you might want to view all facilities in the county to determine where high (or low) emissions values for a given pollutant are originating. To do this, proceed to the Facility MACT HAP Emissions data level.

               iii. Facility MACT HAP Emissions (View Facility, MACT, HAP, and Emissions Data Form)  -  Total emissions by pollutant are shown for all processes at all facilities assigned to this MACT category. The column labeled "MACT Code" indicates that the HAP pollutant emissions are associated with the MACT category.

         After viewing emissions at the facility level, you might want to view all data associated with that facility to make sure that latitude/longitudes, stack parameters, Source Classification Codes (SCC), Standard Industrial Classification (SIC) codes, North American Industry Classification System (NAICS) codes, and other descriptive information are correct. To view this information, select the "All Data" button.

               iv.	All Data (View All Data Form)  -  Detailed records are shown for all facilities included in this MACT category. This detail includes process level HAP emissions, SCCs, stack parameters, latitude/longitudes and address information.

      b.	Filter Data  -  These buttons allow you to filter the current dataset by different attributes. The available filters change depending upon the detail level of the displayed data (e.g., the county level filter is not available on the national level summary form, but is available at the State County MACT level). You can choose one filter after another to progressively narrow down the data to records of interest. For example, on the State County MACT Emissions level, you can filter by state and then by pollutant. The filters available on each data level are:

                 * National Data  -  Pollutant filter.
                 * State County MACT Emissions  -  Pollutant, state, and county filters.
                 * Facility MACT HAP Emissions  -  Facility, pollutant, state, county, and MACT code filters.
                 * All Data  -  Facility, pollutant, state, county, and MACT code filters.

      Filters can be removed by clicking the "Remove Filter" Button. Clicking "Remove Filter" removes all filters applied and returns the dataset to its original form.

      After viewing emissions at the facility level, proceed to "Revise Data" on the "Main Page" if there any omissions or errors that need correction. 
3.	Revise Data
When you select "Revise Data" the "Reviewer Information" form first opens. You must complete this form before continuing. This form collects contact information on the reviewer:
         * Name
         * Organization
         * Phone Number
         * Email Address

Please note:  If you suggest changes to or add emissions values you will need to provide additional documentation for these emission revisions to the docket. (See Section 6 for more information.)

The "Reviewer Information" form will appear every time you return to the revised data forms, however, your contact information will be saved in the drop down list and you can readily select your email address from the list. The "Facility Selection" form opens and allows the user to select a facility for revision. The name of the facility and address information are shown in the selection list as multiple facilities may have similar names. At this point, you can select one of five actions: "Revise Data for Selected Facility," "Add a Facility," "Add Data to an Existing Facility," "Export Facility Data to an Excel File," or "Back to Main." The "Add a Facility" button is discussed in Section 4; the rest are described below.

      Revise Data for Selected Facility  -  Selecting this button opens a form which allows you to select the specific data attributes to be revised. These attributes are:

            a.	Revise Emissions Fields  -  Selecting this option brings up data fields relevant to the emissions value. Fields that can be revised here are: start date, end date, routine emissions (tons per year), pollutant code, and HAP performance level. If an emissions value is changed, the start date, end date, HAP performance level, control measure information, and emissions calculation method code must be updated as well. Because EPA is modeling both short- and long-term risks, you are also asked to indicate the routine emissions maximum hourly rate (in lbs per hour), as well as startup, shutdown, and malfunction (SSM) annual and maximum hourly emissions (and use the comment field to indicate number of SSM occurrences). For EPA to better understand current control measures that are in operation, we are requesting that reviewers indicate the type of control measure associated with each unit. You can indicate if the process is controlled (check box for Yes), select a control measure from the drop down list, and provide additional information in the comment field. If the control measure information is not provided, the emission process will be considered uncontrolled. You can also indicate that the HAP emissions value should be deleted, and provide a reason for this deletion. Please note that you can only enter data into the revision fields. The remaining fields are locked. When you are finished making your changes, select "Save Records" at the bottom of the form to save your revisions and move to another form. 

               Please note:  If you suggest changes to or add emissions values, you will need to provide additional documentation for these emission revisions. (See Section 6 for more information.)

            b.	Revise Stack Fields  -  Selecting this option brings up data fields relevant to the emissions release point. Fields that can be revised here are stack height, stack diameter, stack temperature, exit gas velocity, exit gas flow rate, the emission release point type (stack vs. fugitive), fugitive length, fugitive width, fugitive angle, latitude and longitude, and North American Datum. You can also enter a general comment on the revision. Please note that you can only enter data into the revision fields. The remaining fields are locked. When you are finished making your changes, select "Save Records."

            c.	Revise Process Fields  -  Selecting this option brings up data fields relevant to the process. Fields that can be revised here are MACT code and SCC. You can also enter a general comment on the revision. You only enter data into the revision fields. The remaining fields are locked. When you are finished making your changes, select "Save Records."

            d.	Revise Facility Information  -  Selecting this option brings up data fields that describe the facility. Fields that can be revised here are: tribal code, county name, facility registry identifier, facility category code (major or area), facility name, location address, city, state, and zip code. You can also enter a general comment on the revision, indicate that the facility should be removed from the NEI if it has permanently closed and when it closed, or indicate the facility should be removed from the MACT category. Please note that you can only enter data into the revision fields. The remaining fields are locked.  When you are finished making your changes, select "Save Records."

            e. No Revisions  -  Select this button to indicate you have reviewed the facility data and have no revisions.  You cannot select this button if you have made revisions to the facility. After you make this selection, you will not be able to make revisions to the facility data. 

      Add Data to an Existing Facility  -  Selecting the "Add Data to an Existing Facility" button opens a form which shows all the current HAP emissions for the selected facility. You should scroll to the last row to enter any missing pollutant data. All data fields should be filled in. In addition to providing additional annual emission estimates, you are also asked to indicate the routine emissions maximum hourly rate (in lbs per hour), as well as startup, shutdown, and malfunction (SSM) annual and maximum hourly emissions (and use the comment field to indicate number of SSM occurrences).  You can select "RTR11," Risk and Technology Review 2011 as the data source. When you are finished making your changes, select "Save Records."
      
      Export Facility Data to an Excel File  -  Selecting this option allows you to export the facility data to an Excel file if it facilitates your review of the original NEI facility and emissions data. After clicking this button, you will be asked to which local directory you would like to save the file. If you select this option after making revisions, your revised records will be included. 
      
      Other Options  -  You also have the option of selecting a different facility, returning to the Main Page, reviewing your changes, or preparing the file to submit your changes to EPA.

4.	Add a Facility 
When you select "Add a Facility" on the "Revise Data" form button a new form opens with a single blank record. You can add a facility to this MACT category and enter the HAP emissions and associated descriptive facility and emission release point information. This information includes: tribal code; county name; facility category code (major or area); facility name; location address city, state, and zip code; SIC code; NAICS code; SCC; MACT code; pollutant; routine, startup, shutdown, and malfunction (SSM) emissions values and rates (and number of SSM occurrences); stack parameters; and latitude/longitude. The reviewer should also enter one set of appropriate identifiers: facility registry identifier, unit ID, process ID, and emission release point ID.  Required fields are noted.  If you add emissions for a process that is not associated with the MACT category, please select the appropriate MACT code (from the drop down list) or indicate that it is not a MACT-associated process. When you are finished making your changes, select "Save Records."  To create additional emission unit, process, and HAP emissions records, now select "Add Data to an Existing Facility" and continue with your data entry.

5.	Review Revisions
When you open the "Review Revisions" form, you can export your suggested revisions to Microsoft Excel so that you can print and review them. This form contains five buttons:

         1.	View Emissions Revisions;  
         2.	View Facility Revisions; 
         3.	Export Revisions to Excel File; 
         4.	Submit Revisions; and 
         5.	Back to Main

After selecting options 1 or 2, the corresponding form will open which will display the selected revisions. The Emissions Revisions form contains all additions and revisions entered under the Revise Emissions Fields, Revise Process Fields, and Revise Stack Fields forms as described above.  The Facility Revisions form contains all additions and revisions entered under "Revise Facility Information" form. You can export these revisions by clicking the "Export Revisions to Excel file" button. After clicking this button, you will be asked to which local directory you would like to save the file. The selected revisions will then be exported to a Microsoft Excel spreadsheet. 

You should print out these spreadsheets, review them, and make corrections as necessary. To make corrections, return to the appropriate revision form (as described under Revise Data). Any previously revised data will appear in the revise data forms.

6.	Submit Revisions
Upon completion of all additions and corrections, or acceptance of the data with no revisions, you need to submit your corrections to EPA. First, create a new file containing just the changes. To do so, select the "Submit Revisions" button found on the "Main Page" and on the revision and review summary data forms. Clicking the "Create Revisions File" button will create a spreadsheet file that contains the reviewer's changes. The file will be assigned a name using the following convention: XXXX_Revisions_LastName.xls, where XXXX = 4-6 digit MACT code and LastName = reviewer's last name. You will be prompted to save the new file to a local directory of your choice. In addition to submitting the spreadsheet file to the docket, if you corrected or added emissions values, you should prepare supporting documentation. This can include source test reports, permit information and/or computational information such as emission factors and activity data (throughput). The spreadsheet and supporting documentation must be submitted manually to one of the addresses listed in the next paragraph.
