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 b y the Environmental Protection Agency's (EPA) Offic e 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 p roposed 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 798 08 ), September 3, 2004 (69 FR 5398 0 , October 3, 2005 (70 FR 5751 3 ), and December 19, 2005 (70 FR 75320 ). Directions: All recipients must complete and return this survey by XXXX XX, 20 XX. 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 y our name and address, indicate this on the survey and return it by XXXX XX, 20XX. The survey consis ts 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 NE I database for your facility

. Section 114 of the CAA **does not allow emission data**  to be claimed as confidential

. You must complete both o f the files on the compact disk **electronically**

. As discussed in the cover letter, if y ou believe that disclosure of an y specific information that yo u submit would reveal confidential business information (CBI) or a trade secret, you should clearl y ident ify

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 n ot 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 ma jor 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 tab s . 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

.P lease 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/NE I database presently contains an y information about your facility , these data are entered in the NEI reporting spreadsheet , included on the compact disk (Enclosure 7) . Please correct or up date these data as necessary and fill in an y 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 accuratel y 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 y ou enter. Codes and definitions for the requested d ata are given in the " look up s " and “help” tab s of NATA NEI spreadsheet
