TMDL definition

TMDL means the total maximum daily load limitation of a parameter, representing the estimated assimilative capacity for a water body before other designated uses are adversely affected. Mathematically, it is the sum of wasteload allocations for point sources, load allocations for non-point and natural background sources, and a margin of safety.

TMDL means total maximum daily load.

TMDL means Total Maximum Daily Load, an analysis of pollutant loading to a body of water detailing the sum of the individual waste load allocations for point sources and load allocations for non-point sources and natural background. See 40 CFR §130.2.

Examples of TMDL in a sentence

• PacifiCorp’s TMDL implementation obligations under this Settlement are limited to the water quality-related measures in the Interim Measures set forth in Appendices C and D and any additional or different measures agreed to by PacifiCorp and incorporated into an approved TMDL implementation plan.

• It is the expectation of the Parties that the implementation of the commitments in this Settlement, coupled with Facilities Removal by the DRE, will meet each State’s applicable TMDL requirements.

• PacifiCorp shall implement Keno load allocations in accordance with the approved TMDL implementation plan under Section 6.3 up until the time of transfer of title to the Keno facility to Interior.

• Other Parties reserve whatever rights they may have under existing law to challenge the TMDLs or TMDL implementation plans in the event this Settlement terminates.

• PacifiCorp’s commitment to develop and carry out TMDL implementation plans in accordance with this Settlement is not an endorsement by any Party of the TMDLs or load allocations therein.

More Definitions of TMDL

TMDL means the total maximum daily load limitation of a parameter, representing the estimated assimilative capacity for a water body before other designated uses are adversely affected.

TMDL or “total maximum daily load” means the calculations and plan for meeting water quality standards approved by the EPA and prepared pursuant to 33 U.S.C. § 1313(d) and federal regulations adopted under that law.

TMDL means Total Maximum Daily Load, which is the sum of the individual wasteload allocations for point sources and load allocations for nonpoint sources and natural background.

TMDL or “Total Maximum Daily Load” means the sum of the individual wasteload allocations (WLAs) for point sources and load allocations (LAs) for nonpoint sources and natural background. If a receiving water has only one point source discharger, the TMDL is the sum of that point source WLA plus the LAs for any nonpoint sources of pollution and natural background sources, tributaries, or adjacent segments. TMDLs can be expressed in terms of either mass per time, toxicity, or other appropriate measure.

TMDL means the amount of pollutants specified as a function of one or more water quality parameters that can be dis- charged into a water quality limited surface water segment and still ensure attainment of the applicable water quality standard.

TMDL means the Rock River Total Maximum Daily Load study approved September 28, 2011 by United States Environmental Protection Agency.

TMDL means the Total Maximum Daily Load analysis to achieve water quality standards for dissolved oxygen in Long Island Sound as established by the Department and as approved by the United States Environmental Protection Agency on April 3, 2001.
