Please revise the plans to minimize the impacts. ❑ Your proposed stream crossing appears to be aligned at approximately . Please re- configure your proposed stream crossing to show it aligned approximately perpendicular (between 75° and 105 °). Diffuse Flow and Stormwater ❑ Per the requirements of the Riparian Buffer Rule, you must show that this site meets diffuse flow requirements with a level spreader or other BMP per Chapter 8 of the BMP Manual (see http //portal ncdem org/web /wq /ws/su/bmp- manual). ❑ Please submit a Level Spreader Supplement Form with all required items for each proposed level spreader (see http / /portal ncdenr org/web/wq/ws/su/bmp- manual) ❑ Please show contour lines down slope of the level spreader to show that it has been correctly sited per the BMP Manual. ❑ The slope from the proposed level spreader(s) lip ( ) to the top of bank of the stream exceeds the allowable slope for type of vegetated filter strip (5% for riparian buffer VFS, and 8% for engineered filter strip). You must either relocate the level spreader(s) to a location where the filter strip slope(s) is /are appropriate or provide a BMP that removes 30 percent TN and TP. For each proposed BMP, provide a completed BMP Supplement Form with all the required items (http / /portal ncdenr org/web /wq /ws / su/bmp- manual) ❑ Please provide calculations to show the outlet velocity from outlets) to the wetland(s). A non - erosive velocity of two feet per second or less must be achieved for the peak flow from the 10 -year storm. ❑ [Drainage Area Map and Percent Imperviousness Breakdown] ❑ Please delineate the drainage areas on the site plan (Drainage area map on full plan sheets). ❑ Please provide the overall percent imperviousness of the project, and an inventory of impervious surfaces in each drainage area. The inventory should include all proposed building footprints, roads, driveways, sidewalks, gravel - surfaced areas, amenity areas, etc. ❑ [High Density] Per the requirements of GC , this project is subject to Stormwater Management Plan (SMP) Requirements for Applicants Other Than the North Carolina Department of Transportation (see http //portal ncdenr org/ web /wq /swp /ws/ 401 /certsandpermits /swmanagement). For each proposed BMP, please provide a completed BMP Supplement Form With all required items (see http / /portal ncdenr org/web/wq/ws/su / bmp- manual). ❑ [Low Density] Per the requirements of GC , this project is categorized as low density. For each vegetated stormwater conveyance, please provide a completed Low Density Supplement Form along with all supporting information (see http / /portal ncdenr org/web /wq /ws /su/bmp- manual). ❑ Please provide a BMP Supplement Form with all required items for every BMP on the site (see http //portal ncdenrorg/web/wq/ws/su/bmp- manual). ❑ Please use the most current version of the BMP Supplement Form (see http //portal ncdenr org/web/wq/ws/su/bmp- manual). Mitigation ❑ of compensatory mitigation is required for this project. Please provide a compensatory mitigation plan. The plan must conform to the requirements of 15A NCAC 2H .0500 and must be appropriate to the type of impacts proposed. ❑ Buffer mitigation is required for the proposed buffer impacts. Please submit a mitigation plan detailing the amount of buffer impact for Zone 1 and/or Zone 2 and how the impact will be mitigated. ❑ Please provide documentation from an appropriate mitigation bank or the NCEEP indicating their willingness to accept your request to purchase (type of mitigation) credit to mitigate for the proposed (type of mitigation) impacts listed in your PCN application per Section D. Mitigation provider selection must conform to the requirements of G.S. 143 - 214.11 (for wetland and stream mitigation) or G.S. 143- 214.20 (for riparian buffer mitigation). Other ❑ The application fee is insufficient because over 150 feet of stream and/or over 1 acre of wetland impacts were requested. Please provide $ . This additional fee must be received before your application can be reviewed. ❑ Please provide a signed copy of the application. ❑ Please provide an agent authorization letter for the application signature. ❑ Please indicate which 404 Permit the USACE has authorized for this project. ❑ Please resubmit copies of your information on the January 2009 PCN form or a more recent version. You can download this format the following web address: (see http: / /www.saw.usace.army.mil /WETLANDS /pcn/) ❑ Please submit electronic CAD files showing , via email to ian.mcmillan @ncdenr.gov and provide a CD (TIFF Group 4 format (black and white, not grayscale or color)) along with your response to the additional information requested. ❑ Please provide stream determination documentation on the site (upstream and downstream photos and DWQ stream identification forms). ❑ Please provide a qualitative indirect and cumulative impact analysis for the project. Please see DWQ's policy for guidance on our website at: hgp:Hportal.ncdenr.org/web/wq/sn/ws/401/policies ❑ For areas in nutrient sensitive waters (NSW) or buffered river basins fertilizer specifications for stormwater BMPs should state that that only an initial minimal application of fertilizer to establish the plants shall be used. ❑ Please complete Section of the PCN Form. ❑ Please provide proposed septic fields on all (or) lots showing that additional impacts will not be required. ❑ Please resubmit 3 copies of your information on the July 2009 Variance Application Form. ❑ Variance application forms must be signed by the owner. Please resubmit the application page of the variance application with the owner's signature. ❑ The proposed buffer impacts in your application require a major variance from the Environmental Management Commission. Please submit 3 copies of your information of the July 2009 Variance Application Form with supporting documentation. ❑ Please provide one (1) data CD of full size plans in TIFF Group 4 format (black and white, not grayscale or color).
