Rule and Implementation Information for the Aerospace Industry
On February 3, 2011, the Office of Management and Budget approved the Section 114 Information Collection Request for the aerospace manufacturing and rework industry. The due date for the response is April 4, 2011; please see the Risk and Technology Review section of this webpage for additional information on this data collection effort.

Risk and Technology Review
The following file provides facility-wide emission rates for each of the identified major and synthetic area or synthetic minor sources that submitted data in response to the 2011 data collection survey. EPA took total HAP emissions divided by total gallons of solids from all the material reported at each facility which provided us with lb HAP/gal solids. One approach to addressing all the emission points at aerospace sources is to pursue a facility-wide emission limit similar to what was done previously with Miscellaneous Metal Parts and Products (PDF) (63pp, 413k) or Plastic Parts and Products (PDF) (55pp, 406k). This approach provided flexibility to each facility in those source categories that aerospace facilities may or may not feel necessary.
|5/23/13||Aerospace Facility-Specific Emission Rates|
PLEASE READ: For facilities identified as “Synthetic Area” in the attached file; please confirm your source’s status as such by reviewing the information provided at the bottom of the spreadsheet in the notes. You may then send an electronic mail message to Kim Teal at firstname.lastname@example.org confirming or revising your status. These responses will determine which sources are to be modeled for the risk and technology review currently underway. If we receive no response, we will leave the facility in and plan to model their emissions.
The following Section 114 Information Collection Request (ICR) has been approved by OMB and is being sent to aerospace manufacturing and rework facilities, that are Major or Synthetic Minor sources of hazardous air pollutants (HAP), in the U.S . The due date for the response is April 4, 2011; if you have questions or concerns regarding this data collection please contact Kim Teal at email@example.com. To provide sources the greatest amount of time possible for responding to the survey we are posting the ICR and instructions below; however, the following forms are intended for hard copy submittal only. If sources prefer to submit their information electronically, they may use the following file transfer protocol (FTP) site:
|2/4/11||Aerospace ICR Instructions|
|2/4/11||Aerospace Survey Print Version|
|2/8/11||Aerospace ICR Mailing List|
We have received many questions regarding the definition of electronic components for the purposes of completing the information collection request (ICR) for the aerospace source category. The aerospace rule provided an exemption for electronic components but it did not provide a definition or guidance for "electronic component". Therefore, I suggest that facilities use their best judgment on what constitutes an electronic component. If you have a solid justification, that any reasonable person would accept, for the part or component being an electronic component then please do not report the activities associated with that part or component on the ICR. However, if you question whether or not it would be considered an electronic component then you should report the activities associated with that part or component.
We have received numerous extension requests to the submission deadline for the Information Collection Request (ICR) for Aerospace Manufacturing and Rework. I have received approval from my management to provide the following relief for submission of data.
- April 4, 2011 Major sources must supply only the coating data specific to RTR (i.e., those coatings for which the Aerospace NESHAP provides specific emission limits) modeling needs (see table,Aerospace ICR April 4 2011 data requirements)
- May 4, 2011 Major and Synthetic Minor sources must supply all remaining data on the ICR
