Briefly explain any steps underway or planned to minimize inflow and infiltration.
1.2. Topographic Map. Attach to this application a topographic map of the area extending at least one mile beyond facility property boundaries. This map must show the outiin(
of the facility and the following information. (You may submit more than one map if one map does not show the entire area.)
a. The area surrounding the treatment plant, including all unit processes.
b. The major pipes or other structures through which wastewater enters the treatment works and the pipes or other structures through which treated wastewater is
discharged from the treatment plant. Include outfalls from bypass piping, if applicable.
c. Each well where wastewater from the treatment plant is injected underground.

Miscellaneous Comments
YES_ This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, N U,
/ name/ownership changes). Include conventional WTPs in this group.
YES v 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.
NO 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
