Permitting Update

Quemetco has filed permit applications (Application Nos. 617081, 617080, and 620480) to revise their Title V permit. This project is not related to any requests by Quemetco to increase their process weight/throughput at the facility. These applications can be found on the application table on the Quemetco Permits page.

The permit revision consists of replacing the existing baghouse venting the rotary dryer, with a new baghouse. The existing baghouse is nearing the end of its useful life. The facility is also adding dust augers to support and augment the replacement baghouse and existing waste dust handling system. The project will not result in any potential emission increases. A public notice for the project was published in the San Gabriel Valley Tribune on October 19, 2020 for a 30-day public comment period, which ended on November 20, 2020. The project was also provided to U.S. EPA for review, which ended on December 28, 2020. No comments were received during the comment periods pertaining to the technical analysis of the draft permits and Statement of Basis. A Permit to Construct for the project was issued to Quemetco on January 8, 2021 under Section H of the Facility Permit.

Quemetco is a battery recycling and secondary lead smelter located at 720 S. 7th Avenue, City of Industry, California. The facility has been operating at this location since 1959, originally as Western Lead. In 1970, Quemetco acquired the facility.  The facility recovers lead from automobile batteries as well as other miscellaneous lead scrap materials. The process involves three major steps: crushing, smelting, and refining.  The facility currently processes over a million pounds of batteries per day and operates seven days per week and 16-20 hours per day. The primary pollutants associated with these operations are arsenic, lead, benzene, 1,3- butadiene, and nitrogen oxides (NOx) with arsenic being the biggest contributor to potential risk. Quemetco operates under a South Coast AQMD Title V permit. The facility is also in the RECLAIM program, a cap and trade program for NOx.
