This Erosion Control Plan shall be implemented in accordance with the standards of Burke County. All Erosion Control devices shall shall be installed in accordance local jurisidction standards. 2. Development and related Erosion Control of this Site will occur in phases as follows: - Phase 1 - Initial Development Phase: Clearing and/or grading activities related to construction of dwelling. - Phase 2 - House Construction: Grading activities related to lot preparation for construction of individual homes. 3. Total project area: 1.454t acres; Total disturbed area = 0.75t acres. Disturbing more than 1 acrea with out an approved erosion contol plan is a violation and is subject to a fine. 4. Additional measures to control erosion and sediment may be required by the City Engineering Inspector. 5. Final location of silt fence shall be determined in the field based on actual site conditions. 6. No on -site demolition landfills (i.e., Stump Holes) will be located on this Site. 7. Approval of this plan is not an authorization to grade adjacent properties. When field conditions warrant off -site grading, permission must be obtained from the affected property owner. 8. The Contractor / Builder shall provide property line swales and/or Temporary Diversion Ditches as necessary to properly direct and/or divert surface flows. Swale or ditch placement should be adjusted as necessary per field conditions or as directed by the Inspector. 9. Stabilization is the best form of erosion control. Temporary seeding is necessary to achieve erosion control on large denuded areas and especially when specifically required as part of the construction sequence shown on the plan. All graded slopes must be seeded and mulched within 5 days of completion of grading. All remaining areas are to be seeded and mulched within 14 days. 10. All erosion control devices shall be inspected at least once a week and after each storm event of 0.5" or more. 11 Contractor shall meet requirements set forth in the "New Ground Stabilization Requirements" NPDES permit effective April 1, 2019 for the EPA effluent guidelines. 15. Any downstream storm drainage inlet(s) that might potentially be affected by the construction shall have inlet protection. Inlet protection must be maintained until all areas draining to the inlet are fully stabilized. 16. Any sediment or dirt tracked into the roads by Contractor activity shall be cleaned up immediately. 17. All disturbed areas not built upon will be provided with permanent groundcover. 18. All sloped greater than 2.5:1 shall be stabilized with erosion matting. 19. River Basin: Catawba, Watershed: Lake Rhodhiss (WS-IV) 20. Site must be storm ready for any extended breaks in construction. QEENERAL NOTES: 1. ALL IMPROVEMENTS SHOWN ARE PROPOSED AND ARE SUBJECT TO CHANGE 2.

Identify leaks and repair as soon as feasible, or remove leaking equipment from the project. 4. Collect all spent fluids, store in separate containers and properly dispose as hazardous waste (recycle when possible). 5. Remove leaking vehicles and construction equipment from service until the problem has been corrected. 6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products to a recycling or disposal center that handles these materials. LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE 1. Never bury or burn waste. Place litter and debris in approved waste containers. 2. Provide a sufficient number and size of waste containers (e.g dumpster, trash receptacle) on site to contain construction and domestic wastes. 3. Locate waste containers at least 50 feet away from storm drain inlets and surface waters unless no other alternatives are reasonably available. 4. Locate waste containers on areas that do not receive substantial amounts of runoff from upland areas and does not drain directly to a storm drain, stream or wetland. 5. Cover waste containers at the end of each workday and before storm events or provide secondary containment. Repair or replace damaged waste containers. 6. Anchor all lightweight items in waste containers during times of high winds. 7. Empty waste containers as needed to prevent overflow. Clean up immediately if containers overflow. 8. Dispose waste off -site at an approved disposal facility. 9. On business days, clean up and dispose of waste in designated waste containers. PAINT AND OTHER LIQUID WASTE 1. Do not dump paint and other liquid waste into storm drains, streams or wetlands. 2. Locate paint washouts at least 50 feet away from storm drain inlets and surface waters unless no other alternatives are reasonably available. 3. Contain liquid wastes in a controlled area. 4. Containment must be labeled, sized and placed appropriately for the needs of site. 5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from construction sites. PORTABLE TOILETS 1. Install portable toilets on level ground, at least 50 feet away from storm drains, streams or wetlands unless there is no alternative reasonably available. If 50 foot offset is not attainable, provide relocation of portable toilet behind silt fence or place on a gravel pad and surround with sand bags. 2. Provide staking or anchoring of portable toilets during periods of high winds or in high foot traffic areas. 3. Monitor portable toilets for leaking and properly dispose of any leaked material. Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace with properly operating unit. EARTHEN STOCKPILE MANAGEMENT 1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least 50 feet away from storm drain inlets, sediment basins, perimeter sediment controls and surface waters unless it can be shown no other alternatives are reasonably available. 2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of five feet from the toe of stockpile. 3. Provide stable stone access point when feasible. 4. Stabilize stockpile within the Tmeframes provided on this sheet and in accordance with the approved plan and any additional requirements. Soil stabilization is defined as vegetative, physical or chemical coverage techniques that will restrain accelerated erosion on disturbed soils for temporary or permanent control needs.

Documentation that the required ground stabilization measures have been provided within the required timeframe or an assurance that they will be provided as soon as possible. NOTE: The rain inspection resets the required 7 calendar day inspection requirement. SELF -INSPECTION, RECORDKEEPING AND REPORTING SECTION B: RECORDKEEPING 1. E&SC Plan Documentation The approved E&SC plan as well as any approved deviation shall be kept on the site. The approved E&SC plan must be kept up-to-date throughout the coverage under this permit The following items pertaining to the E&SC plan shall be kept on site and available for inspection at all times during normal business hours. Item to Document Documentation Requirements (a) Each E&SC measure has been installed Initial and date each E&SC measure on a copy and does not significantly deviate from the of the approved E&SC plan or complete, date locations, dimensions and relative elevations and sign an inspection report that lists each shown on the approved E&SC plan. E&SC measure shown on the approved E&SC plan. This documentation is required upon the initial installation of the E&SC measures or if the E&SC measures are modified after initial installation. (b) A phase of grading has been completed. Initial and date a copy of the approved E&SC plan or complete, date and sign an inspection report to indicate completion of the construction phase. (c) Ground cover is located and installed Initial and date a copy of the approved E&SC in accordance with the approved E&SC plan or complete, date and sign an inspection plan. report to indicate compliance with approved ground cover specifications.

[40 CFR 122.41] PART II, SECTION G, ITEM (4) DRAW DOWN OF SEDIMENT BASINS FOR MAINTENANCE OR CLOSE OUT Sediment basins and traps that receive runoff from drainage areas of one acre or more shall use outlet structures that withdraw water from the surface when these devices need to be drawn down for maintenance or close out unless this is infeasible. The circumstances in which it is not feasible to withdraw water from the surface shall be rare (for example, times with extended cold weather). Non -surface withdrawals from sediment basins shall be allowed only when all of the following criteria have been met: (a) The E&SC plan authority has been provided with documentation of the non -surface withdrawal and the specific time periods or conditions in which it will occur.
