REGAN Secretary WILLIAM E. TOBY VINSON, JR. Interim Director The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater Management Permit Modification Application for the subject project on May 10, 2018. A review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please revise the calculations and the design of the BayFilter in accordance with the following comments: a. When determining the number of required cartridges, divide the total annual system sediment load (550.85 lbs according to the submitted calculations) by the capacity of each Bay Filter (175 lbs), in accordance with the BayFilter Design Manual. b. The calculated Maximum Treatment Flow Rate (on the page entitled Determining Number of Cartridges for Volume -Based Design) is the total flow through the system. This flow should be used to calculate the equivalent orifice diameter. c. The conversion of flow rate per cartridge from cfs to gpm is incorrect. Please calculate the flow rate and show that it meets BayFilter MDC 3 (maximum of 0.5 GPM/ft2 of media surface area). 2. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, and 1 hardcopy of other documents. Pdfs must be uploaded using the form at: hqps:Hedocs.deq.nc.gov/Forins/SW ProjectSubmittal Please note that this request for additional information is in response to a preliminary review.
