Miscellaneous Comments
YES This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YES_ This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
limits). Basin Coordinator to make case -by -case decision.
YES_ This permit CANNOT BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS,
etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
