### 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 i ndustrial major source cate gories, as required by section 112(f) of the Clean Air Act. The source of this information is the most recent version of EPA’s Risk and Technology Review (RTR) Program data, updated with data collected by EPA’s Office of Air Quality Planning and Standards.

The Microsoft Access file will enable you to review and suggest revisions to HAP emissions and other descriptive information a ssociated with all facilities in a single Maximum Achievable Control Technology (MACT) category. In structions for using this file to review the data, revise the data, and submit revisions to EPA are outlined below. Section 6 1 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 elemen ts found in this file. The complete outline for

Please note that the category- specific files may contain all emissions data for the facilities identified as belonging to a MACT category. Thus, some of the emissions may be from processes NOT associated with the MACT category of intere st. The column labeled “MACT Code” indicates if the HAP pollutant emissions are associated with the MACT category of interest or another MACT categor y at the facility. For example, if the MACT code is labeled 0107-2, the emissions are described as being associated with “Industrial/Commercial/
Institutional Boilers & Process H eaters – gas.” These are shown to provide a complete dataset for the facility and/or to help the reviewer spot additional processe s which should be assigned to the MACT category.

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 a ny facilities to this file. After reviewing the current data for your MACT cate gory, 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.

01/27/12 22. 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 inte rest. You can sort the columns in ascending or descending order if you wi sh to see the highest or lowest emissions and/or if you want to sort by pol lutant name alphabetically. This form also provides buttons that allow you to change the aggrega tion level (“Options”) of the da ta and/or filter by pollutant (“Filter Data”).

a. Options – These buttons allow you to view summar y 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. Thes e 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 – po llutant level. This form would allow you, for example, to find your county and view total emissions by pollutant from the MACT categor y. 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 may be shown

01/27/12 3for all processes at all facilities assigned to this MACT category. The column labeled “MACT Code” indicates if the HAP pollutant
emissions are associated with th e MACT category or another MACT category at the facility. For exampl e, if the MACT code is labeled 0107-2, the emissions are describe d as being associated with
“Industrial/Commercial/ Institutiona l Boilers & Process Heaters – gas.” These are shown to provide a complete dataset for the facility and/or to help you spot additional processes which should be assigned to 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 (S CC), 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 cat egory. 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 chan ge 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:

01/27/12 4• National Data – Pollutant filter.

• State County MACT Emissions – Pollutant, state, and county filters.

• Facility MACT HAP Emissions – Faci lity, pollutant, state, county, and
MACT code filters.

• All Data – Facility, pollutant, stat e, 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 le vel, proceed to “Revise Data” on the “Main Page” if there any omissions or errors that ne ed correction.

3. Revise Data When you select “Revise Data” the “Reviewer Information” form first opens. You must complete this form before continuing. This fo rm collects contact info rmation 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 revi sions to the docket. (See Section 6 for more information.)

The “Reviewer Information” form will appear ever y 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 Se lection” form opens and allows the user to select a facility for revision. The name of the f acility 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 Facilit y,” “Add a Facility,” “Add Data to an Existing

01/27/12 5Facility,” “Export Facility Data to an Excel Fi le,” or “Back to Main.” The “Add a Facility” button is discussed in Section 4; the rest are described below.

Revise Data for Selected Faci lity – Selecting this button ope ns a form which allows you to select the specific data attributes to be revise d. These attributes are:

a. Revise Emissions Fields – Selecting this option bri ngs up data fields relevant
to the emissions value. Fields that can be revised here are: start date, end date, routine emissions (tons per year), allowable emissions (tons per year), emissions maximum hourly rate (in lb s per hour), pollutant code, and HAP performance level. If an emissions valu e 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 as well as startup, shutdown, and malfunction (SSM ) annual emissions. For EPA to
better understand current control measur es that are in operation, we are requesting that reviewers indicate the t ype of control measur e associated with each unit. You can indicate if the pro cess is controlled (check box for Yes),
select a control measure from the drop down list, and provide additional
information in the comment field. If th e 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 lock ed. When you are fi nished 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.)
