TBNMC TN load allocations for industrial material loss (ML) facilities

Usage

ml_allocations

Format

A data.frame

Details

TN load allocations assigned to industrial material loss facilities under the Tampa Bay Nitrogen Management Consortium (TBNMC) framework. One row per facility, always.

  • entity: Entity name matching the facilities table convention

  • facname: Facility name matching the facilities table convention

  • bay_seg: Integer bay segment identifier (2 = Hillsborough Bay, 4 = Lower Tampa Bay)

  • alloc_tons: Allocation in tons TN per year. For ishared facilities, this is the group's collective allocation (the same value repeated on every member row), not an individual facility allocation

  • ishared: Logical; TRUE when the facility is jointly assessed against a collective allocation shared with other facilities (see alloc_tons)

  • group_id: Character identifier for the shared group a facility belongs to (NA when ishared is FALSE). Provided so shared-group membership can be recovered directly rather than inferred from matching entity + alloc_tons

The three Mosaic material loss facilities (Big Bend, Riverview, Tampa Marine) share a single 9.9 ton/year allocation in Hillsborough Bay (ishared = TRUE on all three rows, group_id = "ml_mosaic_hb"). Kinder Morgan Port Sutton and Tampaplex Material Losses are each assessed individually against their own distinct allocation (ishared = FALSE), despite the misleadingly similar names to the shared IPS Kinder Morgan group; Kinder Morgan Port Manatee is likewise a separate, non-shared facility.
