Identifying Sensitive Environments in the Air Pathway

Highlight 10-13

The above figure is a schematic map (not to scale) of the 4-mile TDL associated with a hypothetical site. From background documents and discussions with appropriate Federal and state agencies, the following information is available:

The area labelled Critical Habitat (Y) is a critical habitat for Federal endangered species. The area labelled Critical Habitat (X) is a critical habitat for a different Federal endangered species. The outlined area at the bottom of the map, directly beneath the source, is a state wildlife refuge. The areas designated as Wetland 1 and Wetland 2 are wetlands as defined in 40 CFR 230.3.

Based on this information, and by referring to HRS Tables 4-23 and 6-18 of the HRS Rule, the following sensitive environments are identified:

  1. The area labelled Critical Habitat (Y) is identified as a critical habitat for Federal endangered species (Y) and assigned a value of 100 points;
  2. The area labelled Critical Habitat (X) is identified as a critical habitat for Federal endangered species (X) and assigned a value of 100 points;
  3. The state wildlife refuge is assigned a value of 75 points;
  4. The area designated as Wetland 1 and the area designated as Wetland 2 are assigned a point value based on total acreage within the TDL (see Hightlight 10 - 15).
