Total Maximum Daily Load (TMDL) means a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources.
Total Maximum Daily Load (TMDL) means a calculation for an impaired water body of the maximum amount of a pollutant the water body can receive and still meet applicable water quality standards in accordance with federal Clean Water Act requirements.
Total Maximum Daily Load (TMDL) means the amount of a given pollutant that may be discharged to a waterbody from point, nonpoint, and natural background sources and still allows attainment or maintenance of the applicable narrative and numerical water quality standards. A TMDL is the sum of the individual Waste Load Allocations (WLAs) for point sources and Load Allocations (LAs) for nonpoint sources and natural background sources of pollution. A TMDL may include a reasonable margin of safety (MOS) to account for uncertainties regarding the relationship between mass loading and resulting water quality. In simplistic terms, a TMDL matches the strength, location and timing of pollution sources within a watershed with the inherent ability of the receiving water to assimilate the pollutant without adverse impact.
Examples of Total Maximum Daily Load (TMDL) in a sentence
Jurisdictions also agreed that if these voluntary commitments were not sufficient to restore the Bay by 2010, the CBP partnership would pursue the regulatory CWA approach and develop a Total Maximum Daily Load (TMDL).
The new Agreement reflects improvements in our scientific knowledge, changes in laws, regulations and policies over the past decade and evolutions that have taken place within the Partnership, in- cluding the Chesapeake Bay Total Maximum Daily Load (TMDL) and jurisdiction’s Watershed Imple- mentation Plans.
The goals of this monitoring effort were to establish pre-project conditions and assess progress in meeting Total Maximum Daily Load (TMDL) requirements (temperature and DO) by monitoring Shasta River water quality.
More Definitions of Total Maximum Daily Load (TMDL)
Total Maximum Daily Load (TMDL) means a calculation for an impaired
Total Maximum Daily Load (TMDL) means the sum of the individual waste load allocations for point sources and load allocations for nonpoint sources and natural background.
Total Maximum Daily Load (TMDL) means the amount of pollutant, or property of a pollutant, from point, nonpoint, and natural background sources, that may be discharged to a water quality-limited receiving water. Any pollutant loading above the TMDL results in a violation of applicable water quality standards.
Total Maximum Daily Load (TMDL) means an allowable pollutant loading to a surface water of the state as defined in R 323.1207.
Total Maximum Daily Load (TMDL) means the maximum amount of a specific pollutant that can be assimilated by a surface water without causing an impairment of designated uses or violating water quality standards. The allowable amount takes into account all sources of that pollutant in a watershed, including point sources and non‐point sources, and requires a portion to be set aside as a margin of safety.
Total Maximum Daily Load (TMDL) means the maximum capacity of a surface water to assimilate a pollutant as established by the Commissioner including pollutants contributed by point and non-point sources and a margin of safety.
Total Maximum Daily Load (TMDL) means the amount of a pollutant that a particular water or stream segment can assimilate and still meet all the requirements of the water quality standards and attain all the assigned beneficial uses.
