The Elioak Loam, Glenelg Loam, and Hazel Loam on-site are classified within hydrologic group B, which have moderate to rapid runoff potential when thoroughly wet. • See sheet ES-2.0 in Appendix M for soils map. Slopes (describe current slopes and note any changes due to grading or fill activities): • There are a few areas of critical slopes on-site(25-45% slopes) • All critical slopes on-site are classified as managed steep slopes. • All of the critical slopes described were man-made during the grading activity associated with previous improvements on-site. Drainage Patterns (describe current drainage patterns and note any changes due to grading or fill activities): • Pre-construction, stormwater runoff flows through piping with outlet protection into a level 1 biofilter. The biofilter has an emergency spillway with a level spreader to convert concentrated flow into sheet flow. • Post-construction, stormwater runoff from the new recreation area will be pre-treated with outlet protection and a gravel diaphragm before entering the existing biofilter. Vegetation: • Pre-construction the site has existing impervious surface, has seeded areas, and contains a mix of deciduous and non-deciduous trees and shrubs. • Post-construction disturbed open areas will be stabilized with vegetative groundcover. Other: • Drainage from the site flows into Biscuit Run, then into Moores Creek which ultimately flows into the Rivanna River. These waterways will not be impacted for this project since they are outside of the scope for this project. 7 EROSION AND SEDIMENT CONTROL NARRATIVE Covenant Upper School I ( Erosion and Sediment Control: Minor Site Plan Amendment 1 Silt Fence[3.051 The County Of Albemarle,Virginia A temporary sediment barrier consisting of synthetic filter fabric stretched across and attached to W170t.I�.Y r'.(VGQS-EERAIG supporting posts and entrenched Used to prevent sediment horn leaving the site.

Sheet No.: ES3.0 16of 16 copyrlpht O 2019 by Wooley Engineering Stormwater Pollution Prevention Plan(SWPPP) The Covenant School Erosion& Sediment Control BMPs: 1. Minimize Disturbed Area and Protect Natural Features and Soil: Describe the areas that will be disturbed with each phase of construction and the methods(signs, fences, etc.)that you will use to protect those areas that should not be disturbed. Describe natural features identified earlier and how each will be protected during construction activity. Also describe how topsoil will be preserved. Include these areas and associated BMPs on your site map(s) also. Maximum disturbed area is detailed in the site plan. BMP Description: Topsoil Stockpiles Topsoil stripped from the immediate construction area will be stockpiled. The stockpile will be in an area that will not interfere with construction phases and at least 15 feet away from areas of concentrated flows of pavement. The slopes of the stockpile will not exceed 2:1 to prevent erosion. A silt fence will be installed around the perimeter of the stockpile. Installation Schedule: 1 Topsoil stockpiles will be established during grading activities. Temporary stabilization will be applied immediately after the slopes of the stockpile have been graded and construction equipment transverses the slopes. Maintenance and Inspection: The area will be inspected weekly for erosion and immediately after storm events. Areas on or around the stockpile that have eroded will be stabilized immediately with erosion controls. Maintenance and inspection procedures for the silt fence. Responsible Staff: Responsible Land Disturber(see page 2) 3. Control Stormwater Flowing Onto and Through the Project: Describe structural practices(i.e., diversions,berms, ditches, storage basins)including design specifications and details used to divert flows from exposed soils,retain or detain flows,or otherwise limit runoff and the discharge of pollutants from exposed areas of the site. 4. Stabilize Soils: Describe controls (i.e.,temporary seeding with native vegetation,hydroseeding, etc.)to stabilize exposed soils where construction activities have temporarily or permanently ceased. Also describe measures to control dust generation. Use of impervious surfaces for stabilization should be avoided whenever possible. BMP Description: Temporary Seeding The establishments of a temporary vegetative cover on disturbed areas by seeding with appropriate rapidly growing annual plants. This protects slopes exposed during construction until permanent vegetative cover can be established. Temporary seeding will apply to all areas on the site that will not be brought to final grade for periods of thirty(30) 8 Stormwater Pollution Prevention Plan (SWPPP) The Covenant School days to one year. Selection of the appropriate seed mixture depends upon the time of year it is to be applied (see schedule on E&S details sheet.) Installation Schedule: Temporary seeding shall be applied to all denuded areas prior to permanent stabilization in the form of either hardscape or permanent seeding. Temporary seeding shall be used on all fill slopes. Maintenance and Inspection: All seeded areas will be inspected weekly during construction activities for failure and after storm events until a dense cover of vegetation has been established. If failure is noticed at the seeded area, the area will be reseeded immediately. After construction is completed at the site,permanently stabilized areas will be monitored until final stabilization is reached Responsible Staff: Responsible Land Disturber(see page 2) ❑ Permanent ® Temporary BMP Description: Permanent Seeding Permanent seeding will be applied after the final design grades are achieved on portions of the site but no later than 14 days after construction activities have permanently ceased. After the entire site is stabilized, any sediment that has accumulated will be removed and hauled off-site for disposal at the Ivy Material Utilization Center. Construction debris, trash and temporary BMPs (including silt fences, material storage areas, sanitary toilets, and inlet protection) will also be removed and any areas disturbed during removal will be seeded immediately. Seedbed Preparation a. In areas where disturbance results in subsoil being the final grade surface, topsoil will be spread over the finished area at minimum depth of 2 to 6 inches. b. The seedbed will be free of large clods,rocks, woody debris and other objectionable materials. c. Fertilizer and lime will be applied to the seedbed according to the manufacturer's recommendations or soil tests. d. The top layer of soil will be loosened to a depth of 3-5 inches by raking, tilling, disking or other suitable means. Grass Selection/Application a. Common areas at the site will be stabilized with a mixture of Tall Fescue, Creeping Red Fescue and Redtop at an application rate of 30 pounds per acre or 0.95 pounds per 1,000 square feet. Lawns will be stabilized with a mixture of Kentucky Blue Grass and Creeping Red Fescue at an application rate of 100 pounds per acre or 2.3 pounds per 1,000 square feet. b. Seed will be applied uniformly by hydroseeding or broadcasting. Where broadcasting is used, the seed will be covered with .25 inch of soil or less,by cultipacking or raking. Installation Schedule: Portions of the site where construction activities have 9 Stormwater Pollution Prevention Plan (SWPPP) The Covenant School permanently ceased will be stabilized, as soon as possible but no later than 14 days after construction ceases. Maintenance and Inspection: All seeded areas will be inspected weekly during construction activities for failure and after storm events until a dense cover of vegetation has been established. If failure is noticed at the seeded area,the area will be reseeded, fertilized, and mulched immediately. After construction is completed at the site,permanently stabilized areas will be monitored until final stabilization is reached. Responsible Staff: Responsible Land Disturber(see page 2) ® Permanent ❑ Temporary BMP Description: Dust Control Dust from the site will be controlled by using a mobile pressure-type distributor truck to apply potable water to disturbed areas. The mobile unit will apply water at a rate of 300 gallons per acre and minimized as necessary to prevent runoff and ponding. Installation Schedule: Dust control will be implemented as needed once site grading has been initiated and during windy conditions (forecasted or actual wind conditions of 20 mph or greater) while site grading is occurring. Spraying of potable water will be performed no more than three times a day during the months of May-September and once per day during the months of October-April or whenever the dryness of soil warrants it. Maintenance and Inspection: At least one mobile unit will be available at all times to distribute potable water to control dust on the project area. Each mobile unit will be equipped with a positive shutoff valve to prevent over watering of the disturbed area. Responsible Staff: Responsible Land Disturber(see page 2) 5. Protect Slopes: Describe controls (i.e., erosion control blankets,tackifiers, etc.) including design specifications and details that will be implemented to protect all slopes. 10 Stormwater Pollution Prevention Plan (SWPPP) The Covenant School 6. Protect Storm Drain Inlets: Describe controls (i.e., inserts, rock-filled bags, or block and gravel, etc.) including design specifications and details that will be implemented to protect all inlets receiving stormwater from the project during the entire duration of the project. BMP Description: Inlet Protection A temporary sediment filter will be used around a storm inlet or curb inlet, in order to prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. See ESC narrative (Appendix M) for design details. Installation Schedule: Inlet protection will be installed around all storm drainage inlets and curb inlets. Maintenance and Inspection: The protection will be inspected weekly and immediately after storm events. If the protection becomes clogged with sediment, the protection will be removed and cleaned or replaced per the manufacturer's recommendation. Responsible Staff: Responsible Land Disturber(see page 2) BMP Description: Outlet Protection Structurally lined Outlet protection used for dissipating energy placed at the outlets of pipes or paved channel sections. Outlet protection is used to prevent scour at stormwater outlets and minimize downstream erosion. See ESC narrative (Appendix M) for design details and placement. Installation Schedule: The outlet protection will be established when the inlet drainage pipe is installed. This form of protection shall be performed on all stormwater outlets by using riprap. Maintenance and Inspection: Inspect to ensure against scour. Responsible Staff: Responsible Land Disturber(see page 2) 7. Establish perimeter controls and sediment barriers: Describe structural practices (i.e., silt fences or fiber rolls) including design specifications and details to filter and trap sediment before it leaves the construction site. BMP Description: Silt Fence Silt fences will be installed along the disturbed area as shown on the site plan. Silt fences will be installed by excavating a 12-inch-deep trench along the line of proposed installation. Wooden posts supporting the silt fence will be spaced 4 to 6 feet apart and driven securely into the ground: a minimum of 18 to 20 inches deep. The silt fence will be fastened securely to the wooden posts with wire ties spaced every 24 inches at the top, mid section, and bottom of the wooden post. The bottom edge of the silt fence will extended across the bottom of the trench and the trench will be backfilled and compacted to prevent stormwater and sediment from discharging underneath the silt fence. 11 Stormwater Pollution Prevention Plan (SWPPP) The Covenant School Installation Schedule: The silt fence will be installed before construction begins at the site and silt fence locations are illustrated on the plan (Appendix M.) Maintenance and Inspection: Silt fences will be inspected weekly and immediately after storm events to ensure it is intact and that there are no gaps where the fence meets the ground or tears along the length of the fence. If gaps or tears are found during the inspection, the fabric will be repaired or replaced immediately. Accumulated sediment will be removed from the fence base if it reaches one-third the height of the silt fence and hauled off-site for disposal. If accumulated sediment is creating noticeable strain on the fabric and the fence might fail from a sudden storm event, the sediment will be removed more frequently. Before the fence is removed from the project area, the sediment will be removed. The anticipated life span of the silt fence is 6 months and will likely need to be replaced after this period. Responsible Staff: Responsible Land Disturber(see page 2) Design Specifications 1. The silt fence will be constructed long enough to extend across the expected flow path. 2. The support posts will be a minimum of 4.5 feet and driven a minimum of 18 to 20 inches in the ground. Posts will be spaced a maximum of 6 feet apart. Fabric will be securely fastened to posts with half-inch staples or 16-gauge wire ties spaced a maximum of 6 inches. 3. A 12-inch trench will be excavated along the uphill side of the silt fence posts. The bottom edge of the fabric will extend across the bottom of the trench. The trench will be backfilled to 4 inches above ground and compacted to bury and secure the bottom of the filter fabric. 8. Retain Sediment On-Site and Control Dewatering Practices: Describe sediment control practices (i.e., sediment trap or sediment basin), including design specifications and details (volume, dimensions, outlet structure)that will be implemented at the construction site to retain sediments on-site. Describe dewatering practices that will be implemented if water must be removed from an area so that construction activity can continue. 12 Stormwater Pollution Prevention Plan (SWPPP) The Covenant School 9. Establish Stabilized Construction Exits: Describe location(s) of vehicle entrance(s) and exit(s),procedures to remove accumulated sediment off-site(i.e., vehicle tracking), and stabilization practices (i.e., stone pads and/or wash racks) to minimize off-site vehicle tracking of sediments and discharges to stormwater. BMP Description: Temporary Stone Construction Entrance A stone entrance shall be constructed utilizing existing driveways, as identified on the site map, to prevent off-site transport of sediment by construction vehicles. The stone entrance will be at least 70 feet long and a minimum of 10 feet wide. This stone area shall be used for washing sediment from vehicles exiting the site. Where sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. Installation Schedule: The stabilized exit will be installed before construction begins and shall utilize existing driveways as shown on the Erosion & Sediment Control plan (ES-1.0). Maintenance and Inspection: The exit will be inspected weekly and after storm events or heavy use. The exit will be maintained in a condition that will prevent tracking or flowing of sediment onto Hickory Street. All sediment tracked, spilled, dropped, or washed onto Hickory Street will be swept up immediately and hauled off-site for disposal at the landfill. Broken road pavement as a result of construction activities on roadways immediately adjacent to the project site will be repaired immediately. Alternate Method: The County inspector may, at their discretion, require the use of a paved construction entrance as an alternate to the stone construction entrance. For details see E&SC plan details in Appendix M. Responsible Staff: Responsible Land Disturber(see page 2) 10. Additional BMPs: Describe additional BMPs that may not fit into the above categories. 13 Stormwater Pollution Prevention Plan(SWPPP) The Covenant School SECTION 5. STORMWATER MANAGEMENT PLAN Stormwater Management BMPs: The stormwater for the proposed recreation area will convey through proposed piping and will be pre-treated with outlet protection and a gravel diaphragm prior to entering the existing biofilter. The existing biofilter has an emergency spillway with a level spreader to convert any concentrated flows to sheet flow prior to exiting the site. A small portion of the recreation area will be covered with porous synthetic turf which will be equipped with underdrains and will act as an infiltration BMP practice. BMP Description: Infiltration Infiltration practices shall be utilized underneath the proposed synthetic turf within the recreation area. See site plan sheet C6.0 for additional details. Installation Schedule: Underdrains and storage aggregate shall be placed installed during construction prior to the porous synthetic turf installation.

An oral report to the department and the VSMP authority shall be provided within 24 hours from the time the operator becomes aware of the circumstances. The following shall be included as information that shall be reported within 24 hours under this subdivision: a. Any unanticipated bypass; and b. Any upset that causes a discharge to surface waters. 2. A written report shall be submitted within five days and shall contain: a. A description of the noncompliance and its cause; b. The period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance. The department may waive the written report on a case-by-case basis for reports of noncompliance under Part III I if the oral report has been received within 24 hours and no adverse impact on surface waters has been reported. 3. The operator shall report all instances of noncompliance not reported under Part III 11 or 2 in writing as part of the SWPPP. The reports shall contain the information listed in Part III 12. NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP authority. Reports may be made by telephone, email, or by fax. For reports outside normal working hours, leaving a recorded message shall fulfill the immediate reporting requirement. For emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone service at 1-800-468- 8892. General Permit No.: VAR10 Page 17 of 23 4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of incorrect information in any report, including a registration statement, to the department or the VSMP authority, the operator shall promptly submit such facts or correct information. J. Notice of planned changes. 1 The operator shall give notice to the department and the VSMP authority as soon as possible of any planned physical alterations or additions to the permitted facility or activity. Notice is required only when: a. The operator plans an alteration or addition to any building, structure, facility, or installation that may meet one of the criteria for determining whether a facility is a new source in 9VAC25-870- 420; b. The operator plans an alteration or addition that would significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants that are not subject to effluent limitations in this general permit; or 2. The operator shall give advance notice to the department and VSMP authority of any planned changes in the permitted facility or activity, which may result in noncompliance with state permit requirements. K. Signatory requirements. 1. Registration statement All registration statements shall be signed as follows a. For a corporation by a responsible corporate officer. For the purpose of this chapter, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-making or decision-making functions for the corporation; or (ii) the manager of one or more manufacturing, production, or operating facilities, provided the manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for state permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures; b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or c. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this chapter, a principal executive officer of a public agency includes: (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency. 2. Reports, etc. All reports required by this general permit, including SWPPPs, and other information requested by the board or the department shall be signed by a person described in Part Ill K 1 or by a duly authorized representative of that person. A person is a duly authorized representative only if: a. The authorization is made in writing by a person described in Part Ill K 1; b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity such as the position of plant manager, operator of a well or a well field, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters for the operator (A duly authorized General Permit No.: VAR10 Page 18 of 23 representative may thus be either a named individual or any individual occupying a named position); and c. The signed and dated written authorization is included in the SWPPP. A copy must be provided to the department and VSMP authority, if requested. 3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because a different individual or position has responsibility for the overall operation of the construction activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to the VSMP authority as the administering entity for the board prior to or together with any reports or information to be signed by an authorized representative. 4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following certification: "I certify under penalty of law that I have read and understand this document and that this document and all attachments were prepared in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this general permit may constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial of a state permit renewal application. The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if this general permit has not yet been modified to incorporate the requirement. M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit after the expiration date of this general permit, the operator shall submit a new registration statement at least 90 days before the expiration date of the existing general permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing general permit. N. Effect of a state permit. This general permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state or local law or regulations. O. State law. Nothing in this general permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U) and "upset" (Part III V), nothing in this general permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance. P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under§§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law or§ 311 of the Clean Water Act General Permit No.: VAR10 Page 19 of 23 Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances), which are installed or used by the operator to achieve compliance with the conditions of this general permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this general permit. R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering surface waters and in compliance with all applicable state and federal laws and regulations. S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of this general permit that has a reasonable likelihood of adversely affecting human health or the environment T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this general permit. U. Bypass. 1. "Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and 3. 2. Notice. a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the date of the bypass. b Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part III I. 3. Prohibition of bypass. a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may take enforcement action against an operator for bypass unless: (1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production; (2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and (3) The operator submitted notices as required under Part III U 2. General Permit No.: VAR10 Page 20 of 23 b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part III U 3 a. V. Upset. 1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology- based state permit effluent limitations if the requirements of Part III V 4 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review. 3. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 4. An operator who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: a. An upset occurred and that the operator can identify the cause(s) of the upset; b. The permitted facility was at the time being properly operated; c. The operator submitted notice of the upset as required in Part III I; and d. The operator complied with any remedial measures required under Part III S. 5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the burden of proof. W. Inspection and entry. The operator shall allow the department as the board's designee, the VSMP authority, EPA, or an authorized representative of either entity (including an authorized contractor), upon presentation of credentials and other documents as may be required by law to: 1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location. For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency. General Permit No.: VAR10 Page 21 of 23 X. State permit actions. State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition. Y. Transfer of state permits. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the Clean Water Act 2. As an alternative to transfers under Part III Y 1. this state permit may be automatically transferred to a new operator if' a. The current operator notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property; b. The notice includes a written agreement between the existing and new operators containing a specific date for transfer of state permit responsibility, coverage, and liability between them; and c. The department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b. 3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site. Z. Severability. The provisions of this general permit are severable, and if any provision of this general permit or the application of any provision of this state permit to any circumstance, is held invalid, the application of such provision to other circumstances and the remainder of this general permit shall not be affected thereby. General Permit No.: VAR10 Page 22 of 23 DEFINITIONS "Business day" means Monday through Friday excluding state holidays. "Commencement of land disturbance" means the initial disturbance of soils associated with clearing, grading, or excavating activities or other construction activities (e.g., stockpiling of fill material). "Construction site" means the land where any land-disturbing activity is physically located or conducted, including any adjacent land used or preserved in connection with the land-disturbing activity. "Final stabilization" means that one of the following situations has occurred: 1. All soil disturbing activities at the site have been completed and a permanent vegetative cover has been established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform (e g , evenly distributed), mature enough to survive, and will inhibit erosion. 2. For individual lots in residential construction, final stabilization can occur by either: a. The homebuilder completing final stabilization as specified in subdivision 1 of this definition; or b. The homebuilder establishing temporary soil stabilization, including perimeter controls for an individual lot prior to occupation of the home by the homeowner, and informing the homeowner of the need for, and benefits of, final stabilization 3. For construction projects on land used for agricultural purposes, final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to surface waters, and areas that are not being returned to their preconstruction agricultural use must meet the final stabilization criteria specified in subdivision 1 or 2 of this definition. "Immediately" means as soon as practicable, but no later than the end of the next business day, following the day when the land-disturbing activities have temporarily or permanently ceased. In the context of this general permit, "immediately" is used to define the deadline for initiating stabilization measures. "Impaired waters" means surface waters identified as impaired on the 2012 § 305(b)/303(d)Water Quality Assessment Integrated Report. "Infeasible" means not technologically possible or not economically practicable and achievable in light of best industry practices. "Initiation of stabilization activities" means: 1. Prepping the soil for vegetative or nonvegetative stabilization; 2. Applying mulch or other nonvegetative product to the exposed area; 3. Seeding or planting the exposed area; 4. Starting any of the above activities on a portion of the area to be stabilized, but not on the entire area; or 5. Finalizing arrangements to have the stabilization product fully installed in compliance with the applicable deadline for completing stabilization. This list is not exhaustive. General Permit No.: VAR10 Page 23 of 23 "Measurable storm event" means a rainfall event producing 0.25 inches of rain or greater over 24 hours. "Stabilized" means land that has been treated to withstand normal exposure to natural forces without incurring erosion damage. Stormwater Pollution Prevention Plan(SWPPP) The Covenant School SECTION 12: INSPECTIONS and MAINTENANCE 12.1 Inspections Project Information: 1. Inspection Personnel: • The Contractor will conduct inspections and the Contractor will bear primary responsibility for inspections of all Erosion and Sediment Control devices and pollution prevention measures to ensure continuing effectiveness. The inspector must be considered Qualified Personnel. Qualified personnel means a licensed professional engineer,responsible land disturber(RLD),or other knowledgeable person who holds a certificate of competence from the board in the area of project inspection, is enrolled in the board's training program for project inspection or combined administrator, and successfully completes such program within one year of enrollment. 2. Inspection Schedule and Procedures: i. Inspections will be conducted at least once every 14 calendar days and within 48 hours following any runoff producing storm event. Where areas have been temporarily stabilized or runoff is unlikely due to winter conditions (e.g., the site is covered with snow or ice,or frozen ground exists) such inspections will be conducted at least once every month. ii. Inspections must include all areas of the site disturbed by construction activity,off-site areas (covered by the permit), and areas used for storage of materials that are exposed to precipitation. Inspectors must 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. iii. Major observations should include: the location(s) of discharges of sediment or other pollutants from the site; amount of rainfall at the construction site since the previous inspection;weather information and a description of any discharges occurring at the time of inspection; location(s) of control measures that need to be maintained; location(s) of control measures that failed to operate as designed or proved inadequate for a particular location; and location(s)where additional control measures are needed that did not exist at the time of inspection. iv. All vegetative and structural erosion and sediment control practices shall be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook. 31 Stormwater Pollution Prevention Plan (SWPPP) The Covenant School v. Contractor shall prepare a report summarizing the scope of the inspection, names and qualifications of personnel making the inspection, the dates of the inspection,major observations relating to the implementation of the SWPPP, and actions taken in accordance with stormwater regulations. The report shall be made and retained as part of the SWPPP. vi.
