Enclosure 2: Instructions

Information Collection Request for the National Emission Standards for Hazardous Air 

Pollutants for Secondary Aluminum Production 

This information request is being conducted by the Environmental Protection Agency's (EPA) 

Office of Air and Radiation (OAR) to assist the EPA Administrator in developing emission 

standards for secondary aluminum production under Clean Air Act (CAA) section 112. The 

survey is being sent under authority of Section 114 of the CAA.

Background:

EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for 

secondary aluminum manufacturing on February 11, 1999 (64 FR 6946) and promulgated final 

regulations on March 23, 2000 (65 FR 15690). Amendments to the rule were promulgated on 

September 24, 2002 (67 FR 59787), December 30, 2002 (67 FR 79808), September 3, 2004 

(69 FR 53980, October 3, 2005 (70 FR 57513), and December 19, 2005 (70 FR 75320). 

Directions:

All recipients must complete and return this survey by XXXX XX, 20XX. Please complete the 

electronic version of the survey for your facility. If your facility is not subject to 40 CFR 63, 

subpart RRR, please fill in your name and address, indicate this on the survey and return it by

XXXX XX, 20XX. The survey consists of two files included on the enclosed compact disk 

(Enclosure 7). A hard copy of the first file (secondary aluminum questionnaire) is included as 

Enclosure 1 for reference purposes. The second file on the compact disk, National Air Toxics 

Assessment /National Emissions Inventory (NATA/NEI) reporting spreadsheet is to be used to 

update or correct data in the NATA NEI database for your facility. Section 114 of the CAA does 

not allow emission data to be claimed as confidential. You must complete both of the files on 

the compact disk electronically.

As discussed in the cover letter, if you believe that disclosure of any specific information that 

you submit would reveal confidential business information (CBI) or a trade secret, you should 

clearly identify such specific information and submit it separately from the non-CBI response. 

Please do not label an entire response "confidential" if only certain portions consist of CBI or 

trade secrets. Enclosures 4 and 6 contain more information about CBI. Do not e-mail a file that 

contains CBI.

The electronic version of the survey contains separate tabs for area sources and major sources of 

HAP. The area source tab does not contain the questions in Part C of Enclosure 1. The major 

source tab does not contain Part D of Enclosure 1. Please pay close attention to the tab titles in 

the Excel spreadsheets and complete the appropriate tabs. Definitions that may be useful in 

completing the secondary aluminum questionnaire are provided in Appendix A to Enclosure 1,

and included in a definitions tab.
Please review and provide updated information for the National Air Toxics Assessment /National 

Emissions Inventory (NATA/NEI) database as requested in the NEI reporting spreadsheet. EPA 

requires accurate information on hazardous air pollutant (HAP) emissions and other risk model 

input data that we will be using to assess risks from the secondary aluminum production source 

category, as required by section 112(f) of the Clean Air Act. The source of this information is 

the 2005 National Air Toxics Assessment National Emissions Inventory (2005 NATA 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. If the NATA/NEI database presently 

contains any information about your facility, these data are entered in the NEI reporting 

spreadsheet, included on the compact disk (Enclosure 7). Please correct or update these data as 

necessary and fill in any blank fields, if possible. If your facility is not presently listed in the 

NATA/NEI database, no data have been entered in the NEI spreadsheet. Please fill in all of the 

fields in the spreadsheet as accurately as possible. Note that the NEI reporting spreadsheet 

contains drop-down tables that may be helpful in completing it. You may include comments and 

qualifying information in the rows below the data that you enter. Codes and definitions for the 

requested data are given in the "lookups" and “help” tabs of NATA NEI spreadsheet. 

Please direct any questions regarding how to complete the Enclosures to Rochelle Boyd with 

EPA’s Office of Air Quality Planning and Standards at 919-541-1390 (e-mail:
