Responses to NCDEQ DEMLR comments received 10/10/2024 below in bold:
1. It appears that an error was made when submitting the revised Supplement-EZ form.The digital and hard copy of
the form that was provided has two identical Wet Pond pages, and no Low Density page. Please submit the Low
Density page of the Supplement, and ensure that it is consistent with what is shown in the provided calculations.
Response: Corrected Supplement-EZ Form is provided with this submittal.
2. From the provided plan sheets, it seems as though there was an error with correcting the forebay's grading. Per Wet
Pond MDC 5,the forebay entrance shall be deeper than the forebay exit.This refers to the excavated bottom of the
forebay, not the sediment storage height. Both the provided plan sheet and the O&M Agreement indicate that the
sediment storage elevation will be lower than the forebay bottom, and the sediment storage appears to be graded
with the intent to meet the MDC, not the excavated bottom of the forebay. Please revise the project package to
meet the MDC, and ensure that all relevant documentation (the Supplement-EZ and the O&M Agreement) is
consistent with what is shown on the plan sheets.
Response: Forebay bottom revised to be lower at entrance than exit. Revised sheet C6.0,O&M, and Supplemental
EZ form are provided with this submittal.
