I didn't have his email address with me at the moment, so I'm sending this to you. Please note that the project number has changed. You only need to submit items that have changed (2 copie< of plans that change, talcs that change, supplement forms that change, etc.) The Division of Water Quality Central Office received a Stormwater Management Permit Application for the subject project on June 15, 2010. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. The concrete level spreader at the entrance to the forebay does not need to be 10-feet wide for DWQ requirements. It can be reduced to the width of a curb. Chapter 8 of the BMP Manual has examples of typical level spreaders,. 2. Clean outs need to be provided for the sand filter underdrains. 3. The sod and topsoil should be removed from the surface of the sand media. This will potentially reduce infiltration rates and increase clogging. Having exposed sand will make future maintenance easier as well. Surge stone or similar is allowed on the top of the sand if you so choose. 4. The 6-inch pipe from the trench drain should discharge into the forebay, instead of directly to the sand chamber. 5. The sand filter profile on sheet C-506 shows 1' to 6" of sand media depth. A minimum of 18" of sand media total depth is required, with at least 12" above the underdrains. 6. Storage for the adjusted water quality volume (2,378 cf) must be provided between the sediment chamber and above the sand media in the sand chamber. Based on the overflow weir elevation (364') from the sand chamber, there is no storage above the sand media. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to July 23, 2010, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail, fax, or email your request for a time extension to the Division at the address and fax number at the bottom of this email. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from the receipt of a completed application to issue the permit. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A. 1 Please reference the State assigned project number SW6100602 on all correspondence.
