Background conditions definition

Background conditions means the biological, chemical, and physical conditions of a water body outside the area of influence of the point source discharge, nonpoint source, or instream activity under consideration.
Background conditions means the biological, chemical, and physical conditions of a water body, outside and up-gradient of the area of influence of the point source discharge, non-point source, or instream activity under consideration. If several sources to any water body exist, background sampling would be undertaken immediately upstream from each source.
Background conditions means the biological (plant and animal species), chemical and physical conditions of the wetland or water body prior to the proposed activity. If the water body is disturbed, it may be necessary to use the biological, chemical and physical conditions of a similar water body as a reference condition.

Examples of Background conditions in a sentence

  • Background conditions are defined from data collected or inferences made from locations within the LSU that are considered un-impacted by human activities and are not static; that is, ranges of acceptable conditions may change depending on modifications by external drivers not under our control (i.e., climate variability) and advancements in the understanding of the ecosystem.

  • Background conditions studied in any individual traffic impact study will nevertheless be limited to six (6) years of reasonable historic background growth.


More Definitions of Background conditions

Background conditions means the biological, chemical, and physical conditions of a water body outside the area of influence of the discharge under consideration. The background sampling location would be upgradient or outside the area of influence of the discharge. If several discharges to any water body exist, background sampling would be undertaken immediately upgradient from each discharge. When assessing background conditions in the headwaters of a disturbed watershed, it may be necessary to use the background conditions of a neighboring or similar watershed as the reference conditions. When assessing background conditions in estuaries, tidal influences must be considered.
Background conditions means the biological, chemical, and physical conditions of a water body, upstream from the point or non-point source of any discharge under consideration. Background sampling location in an enforcement action would be upstream from the point of discharge, but not upstream from other inflows. If several discharges to any water body exist, and enforcement action is being taken for possible violations to the standards, background sampling would be undertaken immediately upstream from each discharge.
