EXISTING SITE CONDITIONS: THE EXISTING SITE IS A VACANT, WOODED, HILLY PARCEL.THE SITE IS GENERALLY WELL DRAINED WITH PRESERVED AND MANAGED STEEP SLOPES. EROSION AND SEDIMENT CONTROL MEASURES HAVE BEEN DESIGNED TO CONFORM TO THE EXISTING SITE SLOPE AND PROTECT THE PERIMETER STREAMS AND ADJACENT PROPERTIES. ADJACENT AREAS: THE SITE IS POSITIONED SOUTH AND EAST OF DICKERSON ROAD AND WEST OF THE EXISTING HUMMINGBIRD LANE SUBDIVISION. IT IS BORDERED BY THE NORTH FORK OF THE RIVANNA RIVER TO THE SOUTH. OFFSITE LAND DISTURBANCE: NO OFF-SITE LAND DISTURBANCE IS PROPOSED. CRITICAL AREAS: MANAGED AND PRESERVED STEEP SLOPES TO BE IMPACTED. STREAMS AND BUFFERS TO BE PROTECTED. WOODLAND PRESERVATION AREAS TO BE MAINTAINED AND PROTECTED WITH TREE PROTECTION FENCING. SEQUENCE OF CONSTRUCTION: 1. NOTIFY ALBEMARLE COUNTY TO SCHEDULE A PRE-CONSTRUCTION MEETING AS REQUIRED. 2. NO EROSION CONTROL MEASURES MAY BE REMOVED DURING THE CONSTRUCTION PROCESS WITHOUT THE APPROVAL FROM THE INSPECTOR ON THE PROJECT. 3. CONTRACTOR SHALL IDENTIFY THE LIMITS OF DISTURBANCE AND INSTALL TREE PROTECTION FENCING WHERE INDICATED ON THE PLANS BEFORE ANY SITE DISTURBANCE SHALL TAKE PLACE. CONTRACTOR SHALL ENSURE THAT TREES TO BE SAVED ARE FLAGGED ALONG THE LIMITS OF CLEARING AND PROTECTED. 4. INSTALL THE PAVED CONSTRUCTION ENTRANCE WITH WASH RACK AS SHOWN ON THE PLANS. CONSTRUCTION ENTRANCE TO BE INSTALLED WHERE CONSTRUCTION VEHICLE ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT BY (VEHICULAR)TRACKING ONTO THE PAVED SURFACE. 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 TRANSPORTING TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER. INSTALL THE WASH RACK UPHILL FROM THE PROPOSED SEDIMENT BASIN. ACSA WILL DETERMINE THE APPROPRIATE METHOD OF SUPPLYING THE WASH RACK. PARKING AND CONSTRUCTION ENTRANCE AREAS SHALL BE CLEARED OF ALL VEGETATION, ROOTS, OR OTHER OBJECTIONABLE MATERIALS BEFORE CONSTRUCTION ROAD STABILIZATION IS INSTALLED. 5. CONTRACTOR DOES NOT HAVE PERMISSION TO CLEAR CUT THE SITE PRIOR TO INSTALLING THE PERIMETER MEASURES AS SHOWN ON THE E&S PLAN. CONTRACTOR SHALL EXPEDITE INSTALLATION OF THE PERIMETER EROSION AND SEDIMENT CONTROL MEASURES AND PROTECT THE SITE WITH THE LEAST AMOUNT OF TREE REMOVAL NECESSARY TO INSTALL THESE MEASURES. INSTALL THE INITIAL CONSTRUCTION MEASURES AS SHOWN ON THE PHASE I EROSION CONTROL PLAN SHEETS. THIS INCLUDES THE SEDIMENT BASINS, SILT FENCE, AND DIVERSION BERMS. STABILIZATION MEASURES SHALL BE APPLIED TO EARTHEN STRUCTURES SUCH AS DAMS, BERMS, AND DIVERSIONS IMMEDIATELY AFTER INSTALLATION. MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. 6. INSTALL ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE PHASE I EROSION CONTROL PLAN. 7. ONCE ALL THE EROSION CONTROL ITEMS HAVE BEEN INSTALLED AS SHOWN ON THE PHASE I EROSION CONTROL PLAN AND THE INSPECTOR HAS APPROVED THE EROSION CONTROL MEASURES,THE CONTRACTOR CAN BEGIN GRADING OPERATIONS. 8. ROUGH GRADE THE SITE TO THE CONTOURS SHOWN ON THE PHASE II EROSION CONTROL PLAN. 9. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT(UNDISTURBED) FOR LONGER THAN 30 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. 10. ONCE THE SITE IS STABILIZED AND THE INSPECTOR HAS GIVEN APPROVAL,THE CONTRACTOR CAN CONVERT THE SEDIMENT BASINS TO THE PERMANENT STORMWATER MANAGEMENT FACILITIES. NO E&S ITEM SHALL BE REMOVED UNLESS THE UPSTREAM AREAS ARE STABILIZED AND THE INSPECTOR GIVES PERMISSION. 11. MAINTAIN ALL EROSION CONTROL MEASURES AS SPECIFIED IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, REMOVING ONLY WHEN APPROVED BY THE LOCAL PROGRAM ADMINISTRATOR IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. 12. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL PROGRAM ADMINISTRATOR.

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 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. 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 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.

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 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.
