Dear Mr. Cain:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Major Modification Application for the subject project on March 15. A
review of that information has determined that the application is not complete. The following
information is needed to continue the stormwater review:
1. Please delineate all wetlands and streams on site or add a note that none exist.
2. Please complete the table on Page 3 of the SWU-101 application with the BUA broken
down by type rather than labeling the total as Other.
3. Only the third sheet of the Supplement EZ form was submitted. Please submit a complete
signed and sealed Supplement EZ form.
4. Please submit full size sheets that show the pre -development and post -development
drainage areas with all existing and proposed BUA clearly labeled.
5. Please submit a new O&M form using the most up-to-date version of the O&M EZ
spreadsheet. The spreadsheet can be found on the Stormwater Design Manual website.
6. Please submit calculations to show that the Bayfilter is designed to treat the runoff from
the design storm.
7. Please submit calculations to show that all outlets are designed to prevent erosion during
the peak flow from the 10-year storm.
