Nature of activity General Scope of Work: 110 The Albemarle County Service Authority(ACSA) Oak Hill Phase 2 Sanitary Sewer Project consists of constructing approximately 2,105 linear feet of sanitary sewer mains and associated manholes via open trench and directional drill methods,providing lateral connections to 20 lots, and providing other associated miscellaneous work and materials. The purpose of this project is to provide public sanitary sewer service to existing homes on private septic drain fields. Land disturbed by construction activities will be restored to pre- ,. construction condition; no change in pervious area is proposed within the project area. What is the function of the construction activity: Municipal Sanitary Sewer Estimated Project Start Date: September 1, 2015 Estimated Project Completion Date: February 29, 2016 Total Land Area of Development: 0.00 acres Estimated Area to be Disturbed: 3.35 acres Intended Construction Sequence: The intended construction sequence is as follows: VON • All existing sewer services shall remain in service during construction. • Install erosion and sediment control measures per plans and in accordance with applicable permit requirements. • Contractor shall test pit and verify locations and depths of existing mains, sewer laterals, and service lines for tie-ins, and all other areas noted on the plans prior to construction. Contractor shall notify engineer if revisions to plans are required. Additionally, Contractor shall test pit existing utilities as identified on the plans. • Construct proposed sewer main and laterals within the existing and proposed temporary and permanent easements. • Appropriate traffic control measures including signage and detour shall be set up and removed daily in accordance with VDOT standards and the plans contained in the Contract Documents. Refer to narrative on plan sheets for details. • Upon acceptance of proposed work, coordinate with the Service Authority forces for isolation and tie-in of mains and services as depicted in the Contract Documents. Provide a minimum of 2 weeks notice to the Service Authority to provide isolation of existing mains for tie-ins. • Perform final surface restoration activities. Contractor shall protect in place all surface features to the degree possible and shall limit work impacts to the areas depicted in the plans. Where required for construction, the Contractor shall remove and replace all existing surface features in like and kind to existing or better condition. Features to be replaced are not specifically depicted on the plans. This note shall apply to all surface features, including but not limited to existing curbs, gutters, sidewalks, vegetation,pavement, and signage. • Contractor shall note the VDOT requirements for timing of final pavement mill and overlay to coincide with warm weather. Contractor's bid shall include provisions for placement and maintenance of temporary pavement prior to final mill and overlay. • Once surface stabilization is complete, temporary erosion and sediment control measures shall be removed. Issued— 10/2014 Stormwater Pollution Prevention Plan(SWPPP)Albemarle County Section 4. Erosion and Sediment Control Plan. All land disturbed by mobilization/construction access to project sites will be restored to their original pre- construction condition. Temporary erosion and sediment control measures will not be removed until all oso disturbed areas upgradient of them are stabilized(as determined with approval by the Albemarle County Service Authority inspector). Stabilization Practices The Contractor shall be required to provide erosion and sediment control measures during all phases of the work. All erosion and sediment control measures shall be in accordance with the approved Erosion and Sediment Control Plan(included with the Contract Documents). The erosion and sediment controls shown on the plans are the minimum required. Depending on construction operations and the results of periodic its` stormwater inspections, the Contractor may be required to provide additional controls at the direction of the Albemarle County Service Authority Inspector. .1101 Unless otherwise indicated, vegetative and structural erosion and sediment control practices shall be constructed and maintained according to minimum standards and specifications included within the latest editions of the Virginia Erosion and Sediment Control Handbook and the Albemarle County Design Standards Manual. The Contractor shall apply permanent or temporary soil stabilization to all disturbed areas within 7 days after final grade is established on any portion of the site. Soil stabilization must also be applied within 7 days to IMO disturbed areas which may not be at final grade,but which will remain undisturbed for longer than 30 days. Soil stabilization measures shall include (but not be limited to) vegetative establishment, mulching, and the early application of gravel base material on areas to be paved. Sediment shall be removed from paved areas on a daily basis. egle Stock piles of soil and other erodible materials shall be stabilized or protected with sediment trapping measures. The Contractor is responsible for the temporary protection and permanent stabilization for stockpiles onsite as well as for materials transported from the project site. The Contractor shall clean streets of mud and dust and take whatever measures necessary to keep adjacent streets clean and dust-free. WNW Effluent from dewatering operations shall be filtered or passed (or both)through an approved sediment trapping device and discharged in a manner that does not adversely affect adjacent properties,wetlands, waterways, or the storm drainage system. The Contractor is responsible for installation and maintenance of any additional control measures necessary to prevent erosion and sedimentation as determined necessary by the Authority Inspector. The Contractor is responsible for providing an individual holding a Responsible Land Disturber Certificate per Albemarle County requirements, who will be responsible for compliance with carrying out the land disturbing activity on this project. SWPPP Inspections VON Inspections required by the general permit shall be conducted by qualified personnel identified by the operator. The inspection log included in Section 12 of this SWPPP shall be completed by the qualified personnel for each Issued— 10/2014 Stormwater Pollution Prevention Plan(SWPPP)Albemarle County inspection; completed logs shall be kept within this SWPPP onsite. Inspections shall be conducted at a frequency of: 1. Inspections shall be conducted at a frequency of(i)at least once every four business days or(ii) at least once every five business days and no later than 48 hours following a measureable storm event. In the event that a measureable storm event occurs when there are more than 48 hours between business days, the inspection shall be conducted on the next business day; and 2. Representative inspections used by utility line installation,pipeline construction, or other similar linear construction activities shall inspect all outfalls discharging to surface waters identified as impaired or for which a TMDL wasteload allocation has been established and approved prior to the term of this general permit. Structural Practices Structural practices anticipated on this project as shown on the Erosion and Sediment Control Plan are: • Temporary silt fence '" • Rock check dam • Paved wash rack • Utility stream crossing Given the relatively short time period expected for disturbance, no other structural practices are planned.

"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 Qat 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. tow "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.

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 ost 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. 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 Ill U 3 a. tow V. Upset. 1.

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. aki* 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; Page 27 of 29 9VAC25-880 (adopted 12/17/2013 -published 2/24/2014 -effective 7/1/2014) Issued— 10/2014 Stormwater Pollution Prevention Plan(SWPPP)Albemarle County two 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 418111 regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency. 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 6011 liability between them;and c.
