Simple feature polygons of NPDES-permitted phosphate mine boundaries in the Tampa Bay watershed

Usage

tbmines

Format

A sf object

Details

Used by util_nps_tbbase to flag land under an active NPDES discharge permit so it can be excluded from non-point source (NPS) load estimation (see util_aa_npsfactors, which excludes CLUCSID = 22). Without this exclusion, a permitted facility's land area would be counted twice: once through the land-use-based NPS model and again through its actual point-source (IPS/DPS) discharge data. The data include the following columns.

  • Location: Character for the mine name

  • Owner: Character for the operating company

  • geometry: The geometry column

Projection is NAD83(2011) / Florida West (ftUS), CRS 6443.

Covers 14 Central Florida phosphate mine sites (13 operated by Mosaic, 1 by CF Industries).
