I got these additional figures indicate that Chemours wants to mine right up to Double Run Creek, upstream from the Santa Fe River.

I got them by following up on the Chemours application to the Army Corps for a permit to mine TiO2 on SRWMD land,

Chemours can’t continue mining without this permit, which it must get from the U.S. Army Corps of Engineers (USACE), because of the successful lawsuit by Miami Waterkeeper, St. Johns Riverkeeper, et al., to revoke the Florida Department of Environmental Protection (FDEP) takeover of federal Clean Water Act permit applications.

See the third page of the USACE application form:

This project was originally review[sic] and approved by the USACE in 2020 pending the issuance of the State Water Quality Certification. Prior to USACE receiving the State Water Quality Certification, the EPA approved Florida’s State 404 Program, which became effective on Dec. 22, 2020, and all USACE pending permits were transferred to the Florida Department of Environmental Protection (FDEP) for processing.

This project was subsequently reviewed, and Phase 1 was approved on June 6, 2022, under the FDEP State 404 Program, Permit no. ST404_137482-022. A portion of the Phase 1 approved impacts have been completed. The approval of Phase 2 is needed for Chemours to continue mining operations without any disruptions. Due to the FDEP being divested of its authority to issue State 404 Program permits on Feb 15, 2024, Chemours has requested the USACE review and approve the entire project for compliance consistency.
