Glossary Consent decree Also referred to as a Consent Order, is a judicial decree expressing voluntary agreement between parties to a suit. Loading capacity The greatest amount of a pollutant that a receiving water body can assimilate and still meet water quality standards. Load or loading The total amount of pollutants entering a water body from one or multiple sources, measured as a rate, as in mass per unit time or per unit area. Load allocation (LA) The portion of the loading capacity attributed to (1) the existing or future nonpoint sources of pollution and (2) natural background sources. Wherever possible, nonpoint source loads and natural loads should be distinguished. Total maximum daily load (TMDL) The sum of the individual wasteload allocations (WLAs) for point sources, load allocations (LAs) for nonpoint sources and natural background, and a margin of safety (MOS). TMDLs can be expressed in terms of mass per time, toxicity, or other appropriate measures that relate to a state’s water quality standard. Wasteload allocation (WLA) The portion of a receiving water’s loading capacity that is allocated to one of its existing or future point sources of pollution (e.g., permitted waste treatment facilities). 41. What are your most significant future needs to develop an effective TMDL compliance program? 42. What other groups or agencies would be useful to contact for further information on this topic? Please provide a contact name, if possible.
