Disturbance Dimensions Under this proposed expansion,we are planning on disturbing a maximum of 17.86 acres. As previously stated within this document, and shown within the provided maps, we are planning to use two different areas to extract the pit-run gravel material needed for this project. Our intent is to remove the needed materials and reclaim/revegetate the pit as stated in our reclamation plan. Owner only intends to strip topsoil and disturb areas within the proposed boundaries. Owner intends to disturb as little land as possible and will make every effort to minimize the operations footprint. Owner plans on mining approximately 8 acres at a time. Reclamation of mined areas will commence when either the mined is completed depleted or erosion begins to occur. The only disturbance will be expanding the footprint of the pit's mining floor, which is caused by continuing to mine into the existing high wall and continuing on to the newly proposed expansion. Roads and Drainage Please refer to the Major Mining Components section of this document to understand the road improvements and upgrades necessary to support the proposed mining operation. The attached Mining Plan Maps are also a good reference to understand the proposed expansion plan.As stated throughout this document, all access road upgrades or additions have been included in the calculation for disturbed areas an included in our reclamation estimate as being fully reclaimed. ,As protecting the area's natural and manmade resources area top priority, owner will ensure all necessary BMP's are in place at all times. They will be installed prior to any ground disturbing activities commencing and will remain in proper working condition throughout the mining operation. Owner is working with the NRCS to ensure proper erosion control measures will be implemented into the proposed mining site. The BMP's summary is listed below. a. BMP List I. Silt Fence-To be installed on all down slope boundaries within the pit that have the potential to receive any run-off within the site.Silt Fence will be trenched in 6" deep and backfilled to ensure a proper operating condition is achieved.As field conditions may present changing conditions throughout the mining process, additional silt fence may/will be installed in areas that are identified as needing it. ii. Straw Wattle-To be installed as needed to slow down any concentrated run-off that may occur within the expansion site.Straw Wattle will also be used in conjunction with installed silt fence in areas where a higher volume of run-off may be seen.Straw Wattle will be dug in and staked. ............ .
