The potential respondents are owners or operators of any existing or new affected source with primary lead processing operations. There is one facility subject to the Primary Lead Processing NESHAP. The NESHAP is applicable to any primary lead processing facility that is engaged in the production of lead metal from lead sulfide ore concentrate and the affected sources are those that meets the criteria established in ?63.1541 of the Primary Lead Processing NESHAP.
The final amendments would reduce the existing main stack lead emission limit to 0.97 pound of lead per ton of lead produced, add a lead emission cap of 1.2 TPY combined for the refining operation stacks and the furnace area stack, and revise testing, reporting, and recordkeeping requirements. These amendments are explained further in the following paragraphs.
The new emisison limit for the main stack has a compliance date of 60 days from the promulgation date. Stack testing for this emission point is required annually under the current standard. Quarterly stack testing from the main stack will be required beginning two years from the promulgation date of the final rule. The new emission limit and stack testing requirements for the furnace area and refining operations, the monitoring requirements, and the related reporting and recordkeeping requiremnts of the final amendments have a compliance date of 2 years from the promulgation date which will allow the facility to implement any changes necessary to meet the new and revised requirements. The final amendments require stack testing for lead compounds on a quarterly basis for three (3) stacks; the main stack, the refining baghouse #8 stack, and the combined stack for the furnace area baghouse #7 and refining operation baghouse #9. No stack testing is required for two of these emission points under the current standard. There are no capital costs associated with the final amendments. Recordkeeping for stack testing will be the same with the exception of frequency.
Effective with the promulgation of the final rule, the affirmative defense provisions require recordkeeping and reporting of malfuctions and corrective actions used for estblishing grounds for affirmative defense. The frequenty of reporing of malfunctions under the affirmative defense provisions is presumed assumed to be low.
For the final amendments to the Primary Lead Processing NESHAP, the components of the total annual burden attributable to this ICR include reading the amendments to the NESHAP; conducting quarterly stack tests and calculating annual emissions, reporting lead stack emissions test results on a quarterly basis, and recorkeeping and reporting for malfunctions.
