TMDL vs vs MS4 Permit MS4 Permit TMDL MS4 MS4 Permit Permit TMDL TMDL

Major Objections Major Objections • 303(d) listed for toxicity (not 303(d) listed for toxicity (not • diazinon) diazinon) • Requires immediate Requires immediate • compliance with numeric compliance with numeric limits limits • TMDL is not needed because TMDL is not needed because • of USEPA’s phase-out of USEPA’s phase-out

Major Objections (cont cont.) .) Major Objections ( • TMDL is redundant with MS4 TMDL is redundant with MS4 • permit permit • Monitoring Program is too Monitoring Program is too • expensive expensive • Source Analysis is too Source Analysis is too • expensive expensive
