INFORMATION COLLECTION REQUEST FOR NESHAP FOR SECONDARY ALUMINUM PRODUCTION RESIDUAL RISK AND TECHNOLOGY REVIEW (RTR)

Part B of the Supporting Statement

1. Respondent Universe

Estimates based on information collected in the development of the current NESHAP and a review of operating permits indicate that the potential respondent universe consists of 400 respondents. All 400 respondents will be required to complete some portion of the electronic survey. The government burden estimate provided in Attachment 3 assumes that 5 percent of facilities will provide documentation that they are not subject to the secondary aluminum production NESHAP. However, it is not known how many of these claims will be valid so all facilities are included in the burden estimate for respondents (in Attachment 2). Attachment 2 lists the various portions of the survey in detail and provides an estimated number of respondents required to complete each portion of the survey. Assumptions used in the burden estimates are that a total of 400 facilities composed of 100 major sources of HAP and 300 area sources of HAP will be subject to the NESHAP.

2. Response Rates

Since the information will be requested pursuant to the authority of CAA section 114, EPA expects that all respondents requested to submit information will do so.
