office may require revisions to the plan and implementation of the revisions to ensure compliance with the
Act.

1. Diversion ditch# 2 (on Sheet C301) must remain intact and functional until the storm drainage system is
installed and replaces the diversion ditch as shown on Sheet C307A in Phase II. Ensure all upstream areas
are properly diverted into storm drainage inlets to direct site runoff into Skimmer Basin# 1.
2. The excavation to fouu the top of dam (TOD) elevation at 570.0-feet of Sediment Basin#2 is not clearly
shown on the plans. Revise topography as necessary on Sheet C303 (and successive sheets) to clearly
show the TOD being excavated at the proposed elevation.
3. Identify Skimmer Basin# 1 and Skimmer Basin# 2 with an appropriate callout on Sheet C-302 and Sheet
C-301, respectively. (Revise any successive sheets, as necessary.)
4. The permanent weir orifice at 563.3-feet in the riser must be temporarily blocked while Sediment Basin#
1 is used for erosion control. In addition, the permanent weir orifice at 565.35-feet in the riser must be
temporarily blocked while the Sediment Basin# 2 is used for erosion control.
5. Recheck the calculations for the skimmer/orifice design for Sediment Basin# 2 and revise as appropriate.
6. Based on the comments above, appropriately revise all relevant sheets and submit two new copies of each
to this office before the start of land disturbing activities.
7. Additional measures may be required - The applicant is responsible for the control of sediment on-site. If
