Exclusion Text

18. New construction or equipment installation or alterations (interior and exterior) to or construction of an addition to an existing structure that is similar to existing land use if the area to be disturbed has no more than five cumulative acres of new surface disturbance. This CATEX encompasses activities that do not have an individual or cumulative significant impact on the environment because: • The activity is of a type that would be consistent with approved military installation or industrial site management plans and is thereby compatible with existing land use for the location; • Actions are areas where the quality of biological resources would be minimal or nonexistent and cultural resources are likely to have been previously identified and addressed (or already disturbed), thereby eliminating potential biological or cultural resource impacts; • The traffic impact (if any) would be limited and not exceed the capability of existing road networks; • Construction would be limited to a type and scale that does not exceed construction already existing in the area; • Construction would be conducted in accordance with applicable SOPs and BMPs; • Indirect (cumulative) impacts from associated infrastructure (e.g., utilities) would be limited in scope; and • Certain types of facilities with potentially significant impacts, e.g., solid or hazardous waste facilities, are excluded from this CATEX.
