Source	TSS outflow concentration (mg/L) at a given Percentile			TP outflow concentration (mg/L) at a given Percentile
Source	25th	50th	75th	25th	50th	75th
ASCE/EPA	11	13	25	0.08	0.13	0.20
CWP	11	17	34	0.07	0.11	0.17
Source	TSS Percent Removal at a given Percentile¹			TP Percent Removal at a given Percentile¹
Source	25th	50th	75th	25th	50th	75th
ASCE/EPA	60	88	94	29	48	69
CWP	60	80	86	39	51	76

¹MnDOT values for mean TSS removal=65% and mean TP removal=52%
