ALBEMARLE COUNTY ENGINEERING GENERAL CONSTRUCTION NOTES FOR EROSION & SEDIMENT CONTROL • 1. The plan approving authority must be notified one week prior to the pre -construction conference, one week prior to the commencement of land disturbing activity, and one week prior to the final inspection. 2. All erosion and sediment control measures will be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment control Handbook and Virginia Regulations VR 625-02-22 Erosion and Sediment Control Regulations. 3. All erosion and sediment control measures are to be placed prior to or as the first step in clearing. 4. A copy of the approved erosion and sediment control plans shall be maintained on the site at all times. 5. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not limits to, off-site borrow or waste areas), the contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving authority. 6. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion and sedimentation as determined by the plan approving authority. 7. All disturbed areas are to drain to approved sediment control measures at all times during land disturbing activities and during site development until final stabilization is achieved. 8. During dewatering operation water will be pumped into an approved filtering device. 9. The contractor shall inspect all erosion control measures periodically and after each runoff -producing rainfall event. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shalt be made immediately. 10. All fill material to be taken from an approved, designated borrow area. 11. All waste material shall be taken to an approved waste area. Earth fill shall be inert materials only, free of roots, stumps, wood, rubbish, and other debris. 12. Borrow or waste areas are to be reclaimed within 7 days of completion per zoning Ordinance Section 5.1.28. 13. All inert materials shall be transported in compliance with Section 13-301 of the code of Albemarle. 14. borrow, fill or waste activity involving industrial -type power equipment shall be limited to the hours of 7:OOAM to 9:OOPM. 15. Borrow, fill or waste activity shall be conducted in a safe manner that maintains lateral support, or order to minimize any hazard to persons, physical damage to adjacent land and improvements, and damage to any public street because of slides, sinking, or collapse. 16. The developer shall reserve the right to install, maintain, remove or convert to permanent Stormwater Management Facilities (where applicable) and all erosion control measures required by this plan regardless of the sale of any lot, unit, building or portion of the property. 17. Temporary stabilization shall be temporary seeding and mulching. Seeding is to be gat 75 lbs/acre, and in the months of September to February to consist of a 50/50 mix of annual ryegrass and cereal winter rye, or in March and April to consist of annual Rye, or May through August to consist of German Millet. Straw mulch is to be applied at EBOlbs/100SF. Alternatives are subject to approved by the County Erosion Control Inspector. 18. Permanent Stabilization shall be lime and fertilizer, permanent seeding, and mulch. Agricultural grade limestone shall be applied at 90lbs/1000sf, incorporated into the top 4-6 inches of soil. Fertilizer shall be applied at 1000lbs/acre and consist of a 10-20-10 nutrient mix. Permanent seeding shall be applied at 180 lbs/acre and consist of 95% Kentucky 31 or tall fescue and 0-5% perennial ryegrass or Kentucky bluegrass. Straw mulch is to be applied at 80lbs/100sf. Altematives are subject to approved by the County EErosion Control Inspector. 19. Maintenance: all measures are to be inspected weekly and after each rainfall. Any damage or clogging to structural measures is to be repaired immediately. Silt Traps are to be cleaned when 50% of the wet storage volume is filled/with sediment. All seeded areas are to be re -seeded when necessary to achieve a good stand of grass. Silt fence land diversion dykes which are collecting sediment to half their height must be cleaned and repaired. 20. All temporary erosion and sediment control measures are to be removed within 30 days of final site stabilization, when measures are no longer needed, subject to approval by the County Erosion Inspector. 21. This plan shall be void if the Owner does not obtain a permit within 1 year of the date of approval. (Water Protection Ordinance Section 17-204G) 22.

C - 5 02 SHEET 6 of 8 UFFETE-re-TZ-fa 4VAC50-60-54 of the Virginia Stormwater Management Program (VSMP) Permit Regulations requires that Stormwater Pollution Prevention Plan (SWPPP) be developed for all regulated land disturbing activities. The SWPPP must include, but not be limited to, an approved erosion and sediment control plan, an approved stormwater management plan, and this Pollution Prevention Plan {PPP) for regulated land disturbing activities, and a description of any additional control measures necessary to address a TMDL as applicable. The plan for implementing pollution prevention measures during construction activities developed on this sheet must be implemented and updated as necessary. Any PPP requirements not included on this sheet must be incorporated into the SWPPP required by 4VAC50-60-54 that must be developed before land disturbance commences. This PPP identifies potential sources of pollutants that may reasonable be expected to affect the quality stormwater discharges from the construction site (both on- and off-site activities) and describes control measures that will be used to minimize pollutants in stormwater discharges from the construction site. OTHER REFERENCED PLANS SWPPP requirements may be fulfilled by incorporating, by reference, other plans. All plans incorporated by reference become enforceable under the VSMP Permit Regulations and General Permit VAR10 for Discharges of Stormwater from Construction Activities. If a plan incorporated by reference does not contain all of the required elements of the PPP, the operator must develop the missing elements and include them in the SWPPP.
