"Linear development project"means a land-disturbing activity that is linear in nature such as,but not limited to,(i)the construction of electric and telephone utility lines,and natural gas pipelines;(ii) construction of tracks,rights-of-way,bridges,communication facilities and other related structures of a railroad company;(iii)highway construction projects;(iv)construction of stormwater channels and stream restoration activities;and(v)water and sewer lines. Private subdivision roads or streets shall not be considered linear development projects. "Postdevelopment"refers to conditions that reasonably may be expected or anticipated to exist after completion of the land development activity on a specific site. "Predevelopment"refers to the conditions that exist at the time that plans for the land development of a tract of land are submitted to the VSMP authority.Where phased development or plan approval occurs (preliminary grading,demolition of existing structures,roads and utilities,etc.),the existing conditions at the time prior to the first item being submitted shall establish predevelopment conditions. "Stabilized"means land that has been treated to withstand normal exposure to natural forces without incurring erosion damage. ' "Stormwater management plan"means a document(s)containing material for describing methods for complying with the requirements of the VSMP Regulation,9VAC25-870. "Virginia Stormwater Management Program(VSMP)authority"means an authority approved by the 111 Board after September 13,2011 to operate a Virginia Stormwater Management Program or the Department. Regulatory Text: 9V AC25-870-76. Linear development projects. Linear development projects shall control postdevelopment stormwater runoff in accordance with a site- specific stormwater management plan or a comprehensive watershed stormwater management plan developed in accordance with these regulations. L • I 2 1 x r ti Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 6 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 I imp Guidance: Section 76 of the VSMP Regulation,9VAC25-870,establishes the requirement that linear development projects control postdevelopment stomiwater runoff in accordance with a site-specific stormwater management plan or a comprehensive watershed stormwater management plan. The purpose of this guidance document is to clarify the implementation of Section 76 with regard to the construction of linear utilities(e.g.,waterlines,sewer lines,electric lines,telephone lines,oil and gas distribution pipelines,etc.) and was developed for use by the Department and local VSMP Authorities. The VSMP Regulation does not distinguish between various types of linear development projects such as aboveground or underground utilities,highway construction,rights-of-way,bridges,tracks and related structures of a railroad company. The Department of Environmental Quality(DEQ)recognizes that the i e construction of aboveground or underground linear utilities may not result in changes to the predevelopment runoff characteristics of the land surface after the completion of construction and final stabilization. Also,the application of the postdevelopment water quantity and water quality controls to these types of projects and the preparation and implementation of a stormwater management plan may int provide minimum water quality benefit. Examples of such projects include: • The installation of underground utilities(e.g.,waterlines,sewer lines,oil and gas distribution pipelines)beneath existing impervious cover(e.g.,asphalt pavement,concrete pavement)that itr will be returned to its predevelopment condition after the completion of construction and final stabilization; • The installation of underground utilities(e.g.,waterlines,sewer lines,oil and gas distribution ian pipelines)beneath existing pervious cover(e.g.,forest/open space,managed turf)that will be returned to its predevelopment condition after the completion of construction and final stabilization;or • The installation of aboveground(i.e.,overhead)utility lines. DEQ staff or the local VSMP authority should utilize their best professional judgment when evaluating aboveground or underground linear utility projects. If the project will not result in significant changes to the predevelopment runoff characteristics of the land surface after the completion of construction and final stabilization,then DEQ or the local VSMP authority,at their discretion,may waive the requirement for the preparation and implementation of a stonnwater management plan. DEQ recognizes that on a site specific basis a stormwater management plan may be required especially if the linear utility project will significantly alter the predevelopment runoff characteristics of the land surface. In addition,the construction of aboveground or underground linear utilities may be conducted without requiring coverage under the General VPDES Permit for Discharges of Stormwater from Construction Activities(Construction General Permit)provided that: • The project does not significantly alter the predevelopment runoff characteristics of the land surface after the completion of construction and final stabilization; • The project is managed so that less than one(1)acre of land disturbance occurs on a daily basis; • The disturbed land where work has been completed is adequately stabilized on a daily basis; imp • The environment is protected from erosion and sedimentation damage associated with the land- disturbing activity; 3 ism Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 7 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 I 1 I • The owner and/or construction activity operator designs,installs,implements,and maintains pollution prevention measures to: > Minimize the discharge of pollutants from equipment and vehicle washing,wheel wash water,and other wash waters; > Minimize the exposure of building materials,building products,construction wastes, trash,landscape materials,fertilizers,pesticides,herbicides,detergents,sanitary waste, and other materials present on-site to precipitation and to stormwater, > Minimize the discharge of pollutants from spills and leaks and implement chemical spill and leak prevention and response procedures; > Prohibit the discharge of wastewater from the washout of concrete; > Prohibit the discharge of wastewater from the washout and cleanout of stucco,paint, form release oils,curing compounds,and other construction materials;and > Prohibit the discharge of fuels,oils,or other pollutants used in vehicle and equipment operation and maintenance. • The owner and/or construction activity operator provides reasonable assurance to DEQ or the local VSMP Authority that all of the above conditions will be satisfied. This may be accomplished by incorporating these conditions into an erosion and sediment control plan developed for the project. As previously noted,DEQ staff or the local VSMP authority should utilize their best professional judgment when evaluating aboveground or underground linear utility projects. If the owner and/or construction activity operator provides reasonable assurance to DEQ or the local VSMP Authority that all of the aforementioned conditions will be satisfied,then the linear utility project may be conducted without requiring coverage under the Construction General Permit. Please note that this does not relieve the owner and/or construction activity operator from complying with any and all other applicable federal, state,and local requirements. DEQ or the local VSMP Authority reserves the right to require a registration statement for Construction General Permit coverage if the aforementioned conditions are not satisfied. If the linear utility project will significantly alter the predevelopment runoff characteristics of the land surface requiring postdevelopment stormwater management or if other site specific conditions warrant Construction General Permit coverage,DEQ or the local VSMP authority may require a registration statement for permit coverage.

No representation is provided regarding the presence or nature of rock within the project limits. The Contract Documents state that all excavations are unclassified. It shall be the Operator's responsibility to determine the nature and extent of rock presence. 3.3.4 Critical Areas Disturbances in steep slope areas will be kept to the minimum required for construction in accordance with Chapter 17 of the Albemarle County Code. These areas are anticipated Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 12 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 1 So within wooded areas at 1622 and 1708 Inglewood Drive. In accordance with Section 02920 of the Project Manual, the Contractor will be required to utilize soil stabilization blankets (or other methods, if approved)to prevent erosion in areas of steep slope. ire 3.4 Estimated Area of Disturbance Total anticipated disturbances at the ground surface outside hard-surface pavement areas tir are estimated at 10,675 square feet(0.2451 acres),and includes disturbances within grassed areas of: 400 LF of installed water main, 20 feet wide; eight (8) fire hydrants at 100 square feet each; and, three (3) meter vault locations at 625 square feet each. However, disturbances associated with this linear development project will not result in changes to the predevelopment runoff characteristics of the land surface after completion of construction and final stabilization. Refer to Section 1 of this SWPPP. 3.5 Intended Sequence of Construction r. All construction methods and materials will conform to the project documents and applicable regulatory requirements including Albemarle County Service Authority standards and/or preferences, City and/or County ordinances, state codes, amendments,and laws. ire Erosion and sediment control measures shall be placed prior to, or as the first step in construction. The Operator shall be responsible for maintaining these measures throughout the life of the project. In accordance with the Contract Documents, it shall be Operator's responsibility to propose a construction schedule to complete all work in the specified contract completion time period, and the Operator shall be responsible for the sequencing, means and methods, scheduling and coordinating the Work, for monitoring the progress of the Work, and for taking appropriate action to keep the Work on schedule. The actual schedule for implementing pollutant control measures will be determined by project construction progress. Down slope protective measures must always be in place before soil is disturbed. Upon re-establishment of seeded areas, and when authorized by Owner or its duly appointed representative(s),after final inspection,the Operator will remove all erosion and sediment controls. it i.

Unless otherwise indicated, all vegetative and structural erosion and sediment control structural practices shall be constructed and maintained according to minimum Standards and Specifications of the Virginia Erosion and Sediment Control Handbook, latest edition. The Operator shall be required to provide erosion and sediment control measures during all phases of the work. All erosion and sediment control measures shall be installed and maintained in accordance with the Contract Documents. The erosion and sediment controls shown on the plans represent the minimum required. The Operator may be required to provide additional controls as necessary to prevent erosion and sedimentation at the direction of the Owner or its duly appointed representative,or in the event that site conditions require additional controls in order to effectively control erosion and sedimentation. All temporary erosion and sediment control measures shall be removed within thirty(30)days after final site stabilization or after the temporary measures are no longer needed, unless otherwise authorized by the Owner or its duly appointed representative. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 1 4.2 Temporary Structural Practices Some controls are intended to function temporarily, and will be used for erosion and sediment control during the construction period. These include: Standard Erosion and Sediment Control Notes; Temporary Silt Fence, denoted as "SF" on the plans; Tree Protection, denoted as "TP" on the plans; and Inlet Protection, denoted as "IP" on the plans Reference is made to Straw Bale Barriers as an additional practice to be utilized if field conditions warrant.

No additional impervious area will be generated as a result of this linear development project; and,there will be no changes in volume/velocity of runoff caused by this project. " Temporary erosion and sediment control measures will be utilized to control stormwater runoff during construction,while permanent seeding measures will control post-development stormwater runoff in the same manner as pre-development conditions. As this project will not result in significant changes to the pre-development runoff characteristics of the land surface upon completion of construction and final stabilization, it is our understanding the preparation and implementation of a separate stormwater management plan will not be required, as such a plan tor would provide minimum water quality benefit. (Interpreted from Guidance Memo No. 15-2003, Postdevelopment Stormwater Management Implementation Guidance for Linear Utility Projects under the Virginia Stormwater Management Program Regulation, 9VAC25-870, dated April 23, 2015.) The Operator shall maintain proper drainage at all times during construction to prevent localized flooding or other detrimental stormwater management conditions. The Operator is required to um strengthen, augment, or provide other erosion control measures as required, in order to control erosion. The Operator shall restore drainage patterns and ground cover conditions to be consistent with original materials and conditions. 5.1 Nearest Receiving Waters I"' The project site is located within Hydrologic Unit Code (HUC) 020802040401-JR14, with the nearest receiving waters to the project site being an unnamed tributary to Meadow Creek. r. li. ire ii. ire hs i" Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 17 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 1 SECTION 6: POLLUTION PREVENTION PLAN A variety of temporary stormwater pollution controls or Best Management Practices(BMPs)have been included in the construction plans for this project. These controls are reflected in the erosion and sediment controls notes and details, as shown in the Erosion and Sediment Control plan. Such control measures are considered part of this SWPPP and are to be installed and maintained as a condition of the VSMP General / Stormwater Management Permit issued for this project and Virginia Erosion and Sediment Control Law. Note: There are no permanent BMPs to be constructed as a part of this project. Vegetated/grassed areas will be permanently stabilized by seeding. Seeding and mulching procedures shall conform to the applicable provisions of the Virginia Erosion and Sediment Control Handbook. The Operator shall be responsible for prevention of discharge of solid materials and wastes to the surface waters adjacent to the site. Water used for construction, which discharges from the site, must originate from a public water supply or private well approved by the Virginia Department of Health. Water used for construction that does not originate from an approved public supply must not discharge from the site, and it to be retained in ponds until it infiltrates and/or evaporates. 1 The Operator must update the plan to reflect its operation and to identify and maintain current descriptions and storage/locations of all potential pollutant sources. Potential sources of pollution include, but are not limited to: litter, construction debris, recyclable materials, on-site sanitary facilities, dumpsters, waste piles, stockpiles, vehicle wash and concrete truck washout locations, fuels, oils, greases, hydraulic fluids, lubricants, paints, stains, soaps, solvents, detergents, chemicals, fertilizers,or other caustic materials. The Operator shall submit a detailed dewatering plan to the Albemarle County Service Authority, or its duly appointed representative,prior to initiating any excavation or dewatering,in accordance with the plan set. 1 I 1 I 1 Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 18 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 r. SECTION 7: POTENTIAL SOURCES OF POLLUTION The following descriptions summarize anticipated potential sources of pollution associated with this project. 7.1 Spill Prevention and Control air Substances that have the potential for polluting surface and/or groundwater must be controlled by any means necessary to ensure there is no discharge from the project area. The Operator shall provide proper storage,handling,and use of all potential pollutant sources. Such measures will be provided to control drips, leaks or spills, and may include (but not be limited to) secondary containment, such as portable dikes,berms, spill containment pallets, drip pans and spill recovery and cleanup kits. All drips, leaks or spills shall be cleaned in a manner consistent with the magnitude of the impact they represent, and be disposed of in accordance with all local, state and/or Federal regulations. This includes the removal, treatment and disposal of affected soil, to prevent impacts to groundwater. All storage containers, regardless of their contents, shall have approved spill containment where required,be in sound condition,and free of rust,cracks or other damage which might compromise the containment. Hoses, valves, fittings, caps, filler nozzles and associated hardware shall be maintained in proper working condition at all times.

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. 1 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.

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. fir V. Upset 1. An "upset," as defined in 8VAC25-870-10, 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 isr 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 his 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. lirr 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 arty 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 it 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. ion Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 61 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 ism I General Permit No.:VAR10 Page 21 of 21 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 Mt 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. 1 1 I I 1 I 1 Barterbrook Phase 2 Water Main Replacement Project(ACSA 20174-02) Page 62 Storm Water Pollution Prevention Plan—April 2017 Albemarle County WPO201700047 1 ir.
