Page 18 Stormwater Pollution Prevention Plan Ivy Creek Nutrient Bank Phase I b. Nutrients shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events. c. Inspections shall be conducted at a frequency of at least once every four business days OR at least every five business days and no later than 48 hours following a measurable storm event (0.25 inches of rain). In the event that a measurable storm event occurs when there are more than 48 hours between business days, the inspection shall be conducted on the next business day. d. Representative inspections used by utility line installation, pipeline construction, or other similar linear construction activities shall inspect all outfalls discharging to surface waters identified as impaired or for which a TMDL wasteload allocation has been established. There are no exceptional waters contiguous with the subject property, as described in 9VAC25- 260-30 A 3 c. SECTION 9: SWPPP INSPECTIONS AND RECORDKEEPING 9.1 Inspections Inspections shall be conducted at least once every four business days or at least every five business days and no later than 48 hours following a measurable storm event (0.25 inches of rain). In the event that a measurable storm event occurs when there are more than 48 hours between normal working business days, the inspection shall be conducted on the next business day. Where areas have been temporarily stabilized or land-disturbing activities will be suspended due to continuous frozen ground conditions and stormwater discharges are unlikely, the inspection frequency may be reduced to once every 30 days per month. If unexpected weather conditions (such as above freezing temperatures or rain or snow events) make discharges likely, the operator shall immediately resume the regular inspection frequency. Inspections will include all areas of the site disturbed by construction activity, off-site areas covered by the state permit, and areas used for storage of materials that are exposed to precipitation. Inspectors will look for evidence of, or the potential for, pollutants entering a stormwater conveyance system. Control measures identified in the SWPPP shall be inspected for proper installation, maintenance, and operation. Discharge locations, where accessible, shall be inspected to ascertain whether control measures are effective in minimizing impacts to receiving waters. Where discharge locations are inaccessible, nearby downstream locations shall be inspected to the extent that such inspections are practicable. Locations where vehicles enter or exit the site shall be inspected for evidence of off-site sediment tracking. If site inspections identify a control measure that is not operating effectively, corrective action shall be performed as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority to maintain the continued effectiveness of the control measures. Any required modifications to controls will be performed prior to the next anticipated storm event but no longer than seven days after discovery. Page 19 Stormwater Pollution Prevention Plan Ivy Creek Nutrient Bank Phase I As part of the inspection, the qualified personnel shall: a. Record the date and time of the inspection and when applicable the date and rainfall amount of the last measurable storm event; b. Record the information and a description of any discharges occurring at the time of the inspection; c. Record any land-disturbing activities that have occurred outside of the approved erosion and sediment control plan; d. Inspect the following for installation in accordance with the approved erosion and sediment control plan, identification of any maintenance needs, and evaluation of effectiveness in minimizing sediment discharge, including whether the control has been inappropriately or incorrectly used: 1. All perimeter erosion and sediment controls, such as silt fence; 2. Soils stockpiles, when applicable, and borrow areas for stabilization or sediment trapping measures; 3. Completed earthen structures,such as dams, dikes, ditches, and diversions for stabilization; 4. Cut and fill slopes; 5. Sediment basins and traps, sediment barriers, and other measures installed to control sediment discharge from stormwater; 6.

Storm inlets that have been made operational to ensure that sediment laden stormwater does not enter without first being filtered or similarly treated;and 8. Construction vehicle access routes that intersect or access paved roads for minimizing sediment tracking; e. Inspect areas that have reached final grade or that will remain dormant for more than 14 days for initiation of stabilization activities; f. Inspect areas that have reached final grade or that will remain dormant for more than 14 days for completion of stabilization activities within seven days of reaching grade or stopping work; g. Inspect for evidence that the approved erosion and sediment control plan, "agreement in lieu of a plan," or erosion and sediment control plan prepared in accordance with department-approved annual standards and specifications has not been properly implemented. This includes but is not limited to: 1. Concentrated flows of stormwater in conveyances such as rills, rivulets or channels that have not been filtered, settled, or similarly treated prior to discharge , or evidence thereof; 2. Sediment laden or turbid flows of stormwater that have not been filtered or settled to remove sediments prior to discharge; 3. Sediment deposition in areas that drain to unprotected stormwater inlets or catch basins that discharge to surface waters. Inlets and catch basins with Page 20 Stormwater Pollution Prevention Plan Ivy Creek Nutrient Bank Phase I failing sediments controls due to improper installation, lack of maintenance, or inadequate design are considered unprotected; 4. Sediment deposition on any property (including public and private streets) outside of the construction activity covered by this general permit; 5. Required stabilization has not been initiated or completed on portions of the site; 6. Sediment basins without adequate wet or dry storage volume or sediment basins that allow the discharge of stormwater from below the surface of the wet storage portion of the basin; 7. Sediment traps without adequate wet or dry storage or sediment traps that allow the discharge of stormwater from below the surface of the wet storage portion of the trap; and 8. Land disturbance outside of the approved area to be disturbed; h. Inspect pollutant generating activities identified in the pollution prevention plan for the proper implementation, maintenance and effectiveness of the procedures and practices; i. Identify any pollutant generating activities not identified in the pollution prevention plan; and j. Identify and document the presence of any evidence of the discharge of pollutants prohibited by this general permit. If the operator has an appropriate inspection form which will be used, a copy of the form should be attached to this plan.

Where a report does not identify any incidents of noncompliance,the report shall contain a certification that the facility is in compliance with the SWPPP and any state permit. Reports should also indicate whether previously noted incidents of noncompliance have been addressed. SECTION 10: TRAINING The following personnel, at a minimum, must receive training, and therefore should be listed individually in the training log in Appendix D: • Personnel who are responsible for the design, installation, maintenance, and/or repair of stormwater controls (including pollution prevention measures); • Personnel responsible for the application and storage of treatment chemicals (if applicable); • Personnel who are responsible for conducting inspections as required; and • Personnel who are responsible for taking corrective actions as required. Page 21 Stormwater Pollution Prevention Plan Ivy Creek Nutrient Bank Phase I These required personnel must be trained to understand the following if related to the scope of their job duties: • The location of all stormwater controls on the site required by this permit, and how they are to be maintained; • The proper procedures to follow with respect to the permit's pollution prevention requirements; and • When and how to conduct inspections, record applicable findings, and take corrective actions. Upon completion of relevant training, record who conducted the training, the date of training, and the individuals that attended the sessions in Appendix D of this SWPPP. SECTION 11: SWPPP AMENDMENTS, MODIFICATIONS, AND UPDATES Amendments, modifications, and updates to this SWPPP will be detailed in Appendix F. Multiple amendments during the course of the construction activity must have a separate sheet for each amendment with the required signed certification, which can be done by copying the sheet in Appendix F for each change. If during inspections by the operator's qualified personnel, or by local, state, or federal officials, it is determined that the existing control measures are ineffective in minimizing pollutants in discharges from the construction site activity, amendments must be made. The operator will amend the SWPPP whenever: a. There is a change in the design, construction, operation, or maintenance that has a significant effect on the discharge of pollutants to surface waters and that has not previously been addressed in the SWPPP; b. During inspections it is determined that the existing controls are ineffective in minimizing pollutants in discharges; c. There is a change in the responsible contractor who will implement each control measure. d. Within seven days following any modification, updates to the SWPPP shall be noted including a record of dates when: 1. Major grading activities occur; 2. Construction activities temporarily or permanently cease on a portion of the site; and 3. Stabilization measures are initiated. e. Controls are replaced or modified due to inappropriate or incorrect use; f. Areas have reached final stabilization and where no further SWPPP inspections are required; g. Properties are no longer under the control of the operator and the dates on which the operator no longer had control over each property; Page 22 Stormwater Pollution Prevention Plan Ivy Creek Nutrient Bank Phase I h. Prohibited discharges occur, the volume released and what actions were taken to minimize the impact; i. Measures are taken to prevent the reoccurrence of any prohibited discharge; and j. Measures are taken to address any evidence identified as a result of a required inspection. Documentation of these changes shall be made on a copy of the site map which shall include the date of the activity, the activity, and shall be signed by the SWPPP coordinator. SECTION 12: NOTICE OF TERMINATION A Notice of Termination must be submitted when an operator no longer wishes to be covered under the General Permit for Stormwater Discharges from Construction Activities. Reasons for termination include SWPPP post-construction control measures are in place and functioning, another operator has assumed control, or coverage under another permit has been obtained. The notice of termination should be submitted no later than 30 days after one of the above conditions are met. The SWPPP operator will coordinate with someone from the Albemarle County prior to the Notice of Termination to ensure that all stormwater management controls are operational and that stabilization measures are in place according to the plans on all portions of the site for which the operator is responsible. The Notice of Termination form is available at the Virginia Department of Environmental Quality web site. Notice of Termination shall be provided to the Albemarle County unless otherwise notified.
