### Instructions for Submitting Data Corrections

Introduction
EPA seeks comment s on hazardous air pollutant (HAP) emissions and other model input data
that we us ed to assess risks from selected industrial major source categories, as required by
sectio n 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 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 outline d below

. Section 6 1 lists specific steps for submitting your final changes to the EPA

. Section 7 of this document defines important term s (e.g., MACT, SIC, SCC, etc.) and all data elements found in this file

. The complete outline for

Please note that the category

- specific files may c ontain all emissions data for the facil ities identified as belonging to a MACT category

. Thus, some of the emissions may be from

processes NOT associated with the MACT category of interest

. The column labeled “MACT
Code” indicates if the HAP pollutant emissions are associated with the MACT category of
interest or another MACT c ategory 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 Heaters

– gas .” These are shown to provide a complete dataset for the facility and/or to help the reviewer spot additional processes which should be assigned to the
MACT category.

The review file contains emissions of HAPs modeled as part of RTR, criteria air pollutants (CAPs), greenhouse gas pollutants (GHGs), and non

- regulated pollutants r eported in the Information Collection Request ( ICR ) data. Only HAPs are modeled as part of the RTR.

1. Application Overview
When this Microsoft Acces s 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 Database5/15/2014 3 After reading these instructions, you should select the “View Summary Data” button to v iew

s ummary d ata 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

. Please note revisions made to the
data on EPA’s website will not be saved. In order to make revisions that will be saved, you will need to download the zipped file to your hard drive and extract the Access file to your hard
drive.

2. View Summary Data After selecting and clicking the “View Summary Data” button
, the form displays national level summary data for all pollutants ass ociated 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 th ese button s, new form s open with data level an d 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, t his 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 would5/15/2014 4 allow you , for example, to find your county and view tota l 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 may b e shown for all processes at all facilities assigned to this MACT category

. The column labeled “MACT Code” indicates if the HAP pollutant
emissions are associated with the MACT category or another MACT

c ategory at the facility

. For exampl e, if the MACT code is labeled
0107

- 2 , the emissions are described as being associated with

“ Industrial/Commercial/ Institutional Boilers & Process Heaters

– gas

. ” These are shown to provide a complete dataset for the facility
and/o r 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
associate d with that facility to make sure that latitude/longitudes, stack parameters, S ource C lassification Codes (SCC), S tandard I ndustrial C lassification (SIC) codes
, North American I ndustry C lassification S ystem ( NAICS ) c odes, 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

– These buttons allow you to filter the current dataset by different
attributes

. The available filters ch ange 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 o f inter e s t

. For example, on the State County MACT Emissions level, you can filter by state and
th en by pollutant

. The filter s available on each data level are:

• National Data

– P ollutant filter

.

• State County MACT Emissions

– P ollutant, state, and county filters

.

• Facility MACT HAP Emissions

– Facility, p ollutant, state, county , and
M ACT c ode filter s

.

• All Data

– Facility, p ollutant , state, county , and MACT c ode filters.

Filters can be removed by clicking the “Remove Filter” Button
