"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. "Predevelopmant"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. "Stonnwater management plan"means a document(s)containing material for describing methods for complying with the requirements of the VSMP Regulation,9VAC25-870. "Virginia Stonnwater Management Program(VSMP)authority"means an authority approved by the Board after September 13,2011 to operate a Virginia Stonnwater Management Program or the Department. Regulatory Text: 9VAC25-870-76. Linear development projects. Linear development projects shall control postdevelopment stonnwater runoff in accordance with a site- specific stonnwater management plan or a comprehensive watershed stormwater management plan developed in accordance with these regulations. 2 Men wether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 9 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WPO201800083 Guidance: Section 76 of the VSMP Regulation,9VAC25-870,establishes the requirement that linear development projects control postdevelopment stonnwater runoff in accordance with a site-specific stonnwater 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 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 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 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 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 stormwater 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; • The environment is protected from erosion and sedimentation damage associated with the land- disturbing activity; 3 Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 10 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WPO201800083 • The owner andor 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. 4 Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 11 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WPO201800083 SECTION 3: NATURE OF ACTIVITY 3.1 Overview It is the policy of the Albemarle County Service Authority (hereinafter referred to as"OWNER") to ensure compliance with the Commonwealth of Virginia's regulations regarding the discharge of stormwater from construction and land disturbing activities associated with the construction of linear pipe and appurtenances, or other facilities, as part of all Authority-owned construction projects.

Secondarily, water service and fire protection within the project vicinity will be dramatically improved. Associated new appurtenance installations include: bends, tees, sleeves, caps, plugs, blow-off assemblies or other fittings;valves and valve/access boxes; fire hydrants; interconnections;water services connections,including water meters and meter boxes;pipe restraint;erosion and sediment control measures; temporary traffic control measures; in-place abandonment of existing water mains and removal of abandoned appurtenances such as existing valve boxes and fire hydrants; and, surface and site restoration. This project does not include stationary construction. All construction activities will progress along each affected street as pipe installations are performed -- and completed. The project will consist of the following basic activities: • Site grading(minor,as part of installations,restoration efforts and abandonment) • Pavement restoration(patching,mill and overlay) • Installation of linear underground utilities and associated services • Other activities(erosion and sediment control;temporary traffic control;and,and all other labor, materials,equipment,incidentals and other means of temporary and/or permanent construction necessary or proper for performing and completing the Work as shown in the documents) Without adequate control, there is the potential for pollutants to be transported by storm water. Construction phase pollutant sources anticipated at the site are: • Disturbed(bare)soils • Vehicle fuels and lubricants • Chemicals associated with building construction and building materials Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 14 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WP0201800083 • Asphalt and asphalt pavement waste • Chlorine for water line flushing • Other pollutants(including but not limited to:uncontaminated effluent(groundwater)from trench de-watering activities;dust;construction debris;litter;recyclable materials;on-site sanitary facilities; dumpsters; waste piles; stockpiles; vehicle wash and/or concrete truck washout locations;paints;stains; soaps;solvents;detergents;mulches;fertilizers;or other caustic materials and petroleum-based products.) 3.3 Site Characterizations 3.3.1 Existing Site Conditions Prior to commencing construction digital photography shall be performed by the OPERATOR clearly documenting the existing site and structure conditions within the work limits and access routes for this Contract.

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 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 1.1 management conditions. The OPERATOR is required to 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 The project site is located within Hydrologic Unit Code (HUC) 020802040202-JR07, with the nearest receiving waters to the project site being Little Ivy • .

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 Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 55 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WPO201800083 General Permit No.:VAR10 Page 18 of 21 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. Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 56 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WP0201800083 General Permit No.:VAR10 Page 19 of 21 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. Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 57 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WPO201800083 General Permit No.:VAR10 Page 20 of 21 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 Ill 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 boards 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. Meriwether Hill Water Main Replacement Project(ACSA Project No. 2017-11) Page 58 Storm Water Pollution Prevention Plan—November 2018 Albemarle County WPO201800083 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 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.
