The authorized discharge shall be in accordance with this cover page, Part I - Discharge Authorization and Special Conditions, Part II - Stormwater Pollution Prevention Plan, and Part III - Conditions Applicable to All VPDES Permits as set forth herein. General Permit No. VAR10 Page 1 of 21 PART I DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS A. Coverage under this general permit. 1 During the period beginning with the date of coverage under this general permit and lasting until the general permit's expiration date, the operator is authorized to discharge stormwater from construction activities. 2. This general permit also authorizes stormwater discharges from support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) located on-site or off-site provided that: a. The support activity is directly related to the construction activity that is required to have general permit coverage for discharges of stormwater from construction activities; b. The support activity is not a commercial operation, nor does it serve multiple unrelated construction activities by different operators; c. The support activity does not operate beyond the completion of the last construction activity it supports; d. The support activity is identified in the registration statement at the time of general permit coverage; e. Appropriate control measures are identified in a stormwater pollution prevention plan and implemented to address the discharges from the support activity areas; and f. All applicable state, federal, and local approvals are obtained for the support activity. B. Limitations on coverage. 1 Post-construction discharges. This general permit does not authorize stormwater discharges that originate from the site after construction activities have been completed and the site, including any support activity sites covered under the general permit registration, has undergone final stabilization. Post-construction industrial stormwater discharges may need to be covered by a separate VPDES permit. 2. Discharges mixed with nonstormwater This general permit does not authorize discharges that are mixed with sources of nonstormwater, other than those discharges that are identified in Part I E (Authorized nonstormwater discharges) and are in compliance with this general permit. 3. Discharges covered by another state permit. This general permit does not authorize discharges of stormwater from construction activities that have been covered under an individual permit or required to obtain coverage under an alternative general permit. 4 Impaired waters and TMDL limitation. Discharges of stormwater from construction activities to surface waters identified as impaired in the 2012 § 305(b)/303(d) Water Quality Assessment Integrated Report or for which a TMDL wasteload allocation has been established and approved prior to the term of this general permit for (i) sediment or a sediment-related parameter (i.e., total suspended solids or turbidity) or (ii) nutrients (i.e., nitrogen or phosphorus) are not eligible for coverage under this general permit unless the operator develops, implements, and maintains a SWPPP that minimizes the pollutants of concern and, when applicable, is consistent with the assumptions and requirements of the approved TMDL wasteload allocations. In addition, the operator shall implement the following items: General Permit No. VAR10 Page 2 of 21 a. The impaired water(s), approved TMDL(s), and pollutant(s) of concern, when applicable, shall be identified in the SWPPP; b. 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; c. Nutrients shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events; and d. The applicable SWPPP inspection requirements specified in Part II F 2 shall be amended as follows: (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 measurable storm event. In the event that a measurable 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. 5. Exceptional waters limitation. Discharges of stormwater from construction activities not previously covered under the general permit issued in 2009 to exceptional waters identified in 9VAC25-260-30 A 3 c are not eligible for coverage under this general permit unless the operator implements the following: a. The exceptional water(s)shall be identified in the SWPPP; b. 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; c. Nutrients shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events; and d. The applicable SWPPP inspection requirements specified in Part II F 2 shall be amended as follows: (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 measurable storm event.

This notification shall provide all available details of the incident, including any adverse effects on aquatic life and the known number of fish killed. The operator shall reduce the report to writing and shall submit it to the department and the VSMP authority within five days of discovery of the discharge in accordance with Part III 12. Unusual and extraordinary discharges include but are not limited to any discharge resulting from: 1 Unusual spillage of materials resulting directly or indirectly from processing operations; 2. Breakdown of processing or accessory equipment; 3. Failure or taking out of service of some or all of the facilities; and 4 Flooding or other acts of nature. I. Reports of noncompliance. The operator shall report any noncompliance which may adversely affect surface waters or may endanger public health. 1 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 Ill 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 21 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 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. 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. 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 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 Section 12 - Inspection Logs General Information (see reverse for instructions) Name of Project CGP Tracking No. Inspection Date and Time Inspector Name,Title& Contact Information Present Phase of Construction Inspection Location (if multiple inspections are required, specify location where this inspection is being conducted) Inspection Frequency(Note:you maybe subject to different inspection frequencies in different areas of the site.Check all that apply ) Increased Frequency ❑ Every 4 business days ❑ Every 5 business days and within 48 hours of a 0.25"rain (for areas of sites discharging to sediment or nutrient-impaired waters or to waters designated as Tier 2,Tier 2.5,or Tier 3) Reduced Frequency - ❑ Once per month (far stabilized areas) - ❑ Once per month and within 24 hours of a 0.25" rain (for arid,semi-arid, or drought-stricken areas during seasonally dry periods or during drought) - ❑ Once per month (for frozen conditions where earth-disturbing activities are being conducted) Was this inspection triggered by a 0.25"storm event? ❑Yes ❑ No If yes, how did you determined whether a 0.25" storm event has occurred? ❑ Rain gauge on site ❑ Weather station representative of site.Specify weather station source: Total rainfall amount that triggered the inspection (in inches): Unsafe Conditions for Inspection Did you determine that any portion of your site was unsafe for inspection per CGP Part 4.1.5? ❑ Yes ❑ No If"yes",complete the following: - Describe the conditions that prevented you from conducting the inspection in this location: - Location(s) where conditions were found: Page 1 of 5 Instructions for Filling Out "General Information" Section Name of Project Enter the name for the project.

If only one inspection is conducted for your entire project, enter"Entire Site." If necessary, complete additional inspection report forms for each separate inspection location. Inspection Frequency Check the box that describes the inspection frequency that applies to you. Note that you may be subject to different inspection frequencies in different areas of your site.If your project does not discharge to a "sensitive water" (i.e., a water impaired for sediment or nutrients, or listed as Tier 2,2.5, or 3 by your state or tribe) and you are not affected by any of the circumstances described in CGP Part 4.1 4, then you can choose your frequency based on CGP Part 4.1.2-either weekly,or every other week and within 24 hrs of a 0.25 in storm event. For any portion of your site that discharges to a sensitive water,your inspection frequency for that area is fixed under CGP Part 4.1.3 at weekly and within 24 hrs of a 0.25 inch storm event. If portions of your site are stabilized,are located in arid,semi-arid, or drought-stricken areas,or are subject to frozen conditions,consult CGP Part 4.1 4 for the applicable inspection frequency Check all the inspection frequencies that apply to your project. Was This Inspection Triggered by a 0.25 Inch Storm Event? If you were required to conduct this inspection because of a 0.25 inch (or greater) rain event,indicate whether you relied on an on-site rain gauge or a nearby weather station (and where the weather station is located).Also,specify the total amount of rainfall for this specific storm event. Unsafe Conditions for Inspection Inspections are not required where a portion of the site or the entire site is subject to unsafe conditions.See CGP Part 4.1.5.These conditions should not regularly occur, and should not be consistently present on a site. Generally, unsafe conditions are those that render the site (or a portion of it) inaccessible or that would pose a significant probability of injury to applicable personnel. Examples could include severe storm or flood conditions, high winds, and downed electrical wires. If your site, or a portion of it,is affected by unsafe conditions during the time of your inspection, provide a description of the conditions that prevented you from conducting the inspection and what parts of the site were affected. If the entire site was considered unsafe,specify the location as "Entire site" Condition and Effectiveness of Erosion and Sediment(E&S) Controls (CGP Part 2.1) (see reverse for instructions) Type/Location of E&S Control Repairs or Corrective Date on Which Notes [Add an additional sheet if Other Action Maintenance or necessary] Maintenance Required?* Corrective Action First Needed?* Identified? 1.

Page 2 of 5 Instructions for Filling Out the "Erosion and Sediment Control" Table Type and Location of ERR Controls Provide a list of all erosion and sediment (E&S) controls that your SWPPP indicates will be installed and implemented at your site.This list must include at a minimum all E&S controls required by CGP Part 2.1.2. Include also any natural buffers established under CGP Part 2.1.2.1 Buffer requirements apply if your project's earth-disturbing activities will occur within 50 feet of a surface water You may group your E&S controls on your form if you have several of the same type of controls (e.g.,you may group "Inlet Protection Measures", "Perimeter Controls", and "Stockpile Controls" together on one line), but if there are any problems with a specific control,you must separately identify the location of the control,whether repairs or maintenance or corrective action are necessary, and in the notes section you must describe the specifics about the problem you observed. Repairs or Other Maintenance Needed? Answer"yes" if the E&S control requires a repair of any kind (due to normal wear and tear,or as a result of damage) or requires maintenance in order for the control to continue operating effectively At a minimum, maintenance is required in the following specific instances: (1) for perimeter controls,whenever sediment has accumulated to Y or more the above-ground height of the control (CGP Part 2.1.2.2.b), (2) where sediment has been tracked-out onto the surface of off-site streets or other paved areas (CGP Part 2.1.2.3.d); (3) for inlet protection measures,when sediment accumulates, the filter becomes clogged, and/or performance is compromised (CGP Part 2.1.2.9.b); and (4) for sediment basins, as necessary to maintain at least Y of the design capacity of the basin (CGP Part 2.1.3.2.b). Note: In many cases, "yes" answers are expected and indicate a project with an active operation and maintenance program.You should also answer"yes" if work to fix the problem is still ongoing from the previous inspection. Corrective Action Needed? Answer"yes"if during your inspection you found any of the following conditions to be present (CGP, Part 5.2.1) (1) a required E&S control was never installed,was installed incorrectly,or not in accordance with the corresponding CGP Part 2 or 3 requirement; (2) you become aware that the inadequacy of the E&S control has led to an exceedance of an applicable water quality standard; or (3) EPA requires corrective action for an E&S control as a result of a permit violation found during an inspection carried out under Part 4.2. If you answer"yes",you must take corrective action and complete a corrective action report,found at www.epa.gov/npdes/stormwater/swppp.Note: You should answer"yes" if work to fix the problem from a previous inspection is still ongoing. Date on Which Maintenance or Corrective Action First Identified? Provide the date on which the condition that triggered the need for maintenance or corrective action was first identified.If the condition was just discovered during this inspection, enter the inspection date.If the condition is a carryover from a previous inspection,enter the original date of the condition's discovery Notes For each E&S control and the area immediately surrounding it, note whether the control is properly installed and whether it appears to be working to minimize sediment discharge.
