effluent standards and limitations, water and sediment quality standards and
other legally applicable requirements pursuant to subsections (1) through (4)

average monthly and maximum daily quantitative mass and/or concentration

For domestic wastewater facilities, average weekly and monthly quantitative
concentration and mass limitations, or other such appropriate limitations for
the level of pollutants and the authorized discharge;
