TOTAL MAXIMUM DAILY LOAD. Nothing in this Agreement shall establish any current or future apportionment or percentage of any impairment or pollutant allocation for any TMDL OCBMAP reduction requirements in any water body identification (WBID) within or flowing into or from the Orange Creek basin, the City of Gainesville, or Alachua County.
TOTAL MAXIMUM DAILY LOAD. (TMDL) listing and de-listing rule adopted and implemented
TOTAL MAXIMUM DAILY LOAD. (TMDL). A calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. TMDLs have been approved by EPA for Zorinsky Lake and Papillion Creek Watershed. A September 2002 TMDL addresses Zorinsky Lake for parameters of concern: siltation, nutrients and organic enrichment/low dissolved oxygen. TMDL for Papillion Creek Watershed was approved in October 2009 for E. coil bacteria for the segments identified in Table 1. Table 1. Papillion Creek Watershed Segments of Impaired Waterbodies. Segment Stream Segment Location MT1-10100 Papillion Creek – Big Papillion Creek confluence with West Papillion Creek to Missouri River MT1-10110 Big Papillion Creek - Little Papillion Creek to confluence with West Papillion Creek MT1-10111 Little Papillion Creek - Xxxxxx Creek to confluence with Big Papillion Creek MT1-10111.1 Xxxx Creek MT1-10120 Big Papillion Creek - Butter Flat Creek to confluence with Little Papillion Creek MT1-00000 Xxxx Xxxxxxxxx Creek - South Papillion Creek to Confluence with Big Papillion Creek Water quality standards are set by States, Territories, and Tribes. They identify the uses for each waterbody, for example, drinking water supply, contact recreation (swimming), and aquatic life support (fishing), and the scientific criteria to support that use. A TMDL is the sum of the allowable loads of a single pollutant from all contributing point and non- point sources. The calculation must include a margin of safety to ensure that the waterbody can be used for the purposes the State has designated. The calculation must also account for seasonal variation in water quality. The Clean Water Act, Section 303, establishes the water quality standards and TMDL programs, and for Nebraska such standards and programs are administered by the Nebraska Department of Environmental Quality.

TOTAL MAXIMUM DAILY LOAD. TMDLs include a quantified pollutant reduction target. According to EPA regulation (40 CFR 130.2(i)), TMDLs can be expressed as mass per unit of time, toxicity, percent load reduction or other measure. TMDLs should address, either singly or in combination, each listed pollutant/waterbody combination.
