Norslien Quarry.. #74-95.. Town of Vermont <br /> <br />The submitted erosion control and storm water management plan meets the needs of the site. <br /> <br />The site consists of approximately 80 acres that will be used for limestone products, such as <br />gravel, and other forms of mineral extraction. The proposed future land use is agriculture <br />(pasture, row-crops) after the minerals are extracted. Presently, the runoff goes to the south and <br />is internally drained. All runoff from the 80 acres of the gravel pit will be directed to the existing <br />low areas and is internally drained. <br /> <br />The following conditions must be implemented: <br /> <br />1. The sediment pond must be expanded and updated according to the needs of the site. The <br />site is internally drained and will remain internally drained. <br />2. The entire berm area and slopes are vegetated according to the reclamation plan. <br />3. The existing internally drained system meets the needs of the site. The detention basin <br />shall be enlarged, as needed. <br />4. Currently, the site is fenced. <br />5. The reclamation plan and final slopes are presented on map of the last page of the plan. <br />.6. The stockpiles and soil berms around the perimeter of the quarry will be graded as <br />presented in the plan. The bottom of the quarry will be topsoiled 9 to 12 inches and the <br />slopes topsoiled 6 to 9 inches and graded. <br />7. The slopes outside of the lake area will be graded 3: 1. The vertical faces will be blasted <br />down into a bench pattern, and where possible, slopes 3: 1 will be established. <br />8. The clear stone weepers and erosion control and drainage structures will be used as <br />needed to accomplish the final drainage pattern. <br />9. The entire berms at the east of the property shall be restored and slope according to the <br />reclamation plan. <br />
