Water quality standards - ACCURATE ANSWERS✔✔ state/tribal
requirements that define the water quality goals of lakes, streams, or
other water bodies by designating the beneficial uses and protecting the
uses through numeric/narrative standards that maintain the chem, phys,
and bio integrity of a waterbody
CWA Section 303(d) - ACCURATE ANSWERS✔✔ establishes a
process for states/territories/tribes to identify impaired waters/water

identifies the amount of a specific pollutant/property of a pollutant from
point, nonpoint, and natural background sources, including a margin of
