The watershed drains 34.92 sq. miles of Albemarle County, Virginia, including the southern portion of the City of Charlottesville. Moore's Creek flows approximately 11 miles from its source in the Ragged Mountains to its confluence with the Rivanna River in Charlottesville. The watershed is predominantly forested, with residential areas, grasslands, and urban areas the other major land uses. Water quality sampling on Moore's Creek between August 1991 and January 2002 found that 14.5% of the water samples violated the instantaneous fecal coliform standard of 1000 cfu1100 ml and that the 30-day geometric mean standard of 200 cfu1100 ml was violated 59% of the time. Due to the high percentages of violations (over 10%) the stream was placed on Virginia's 1998 303(d) list of impaired waters. A 6.37-mile reach from the intersection of U.S. Route 29 and County Route 1106 to the confluence of the Rivanna River was listed as impaired due to elevated levels of fecal coliform bacteria. In response to the impairment, a Total Maximum Daily Load (TMDL) for fecal coliform bacteria has been developed for Moore's Creek. The TMDL takes into account all sources of fecal coliform bacteria, including background sources, considers critical conditions and seasonal variability, and includes a margin of safety. Incorporation of E. coli into Virginia's Water Quality Standards, January 2011, Geometric Mean of 126 e. coli cfu1100 mL, is reflected in the updated TMDL equation and will be updated in permits as appropriate. Community participation has been encouraged throughout the process. Details are reviewed below. Critical Conditions An analysis of the water quality monitoring record in Moore's Creek shows that violations of 30-day geometric mean standard occur more than 10% of the time in every month of the year and that violations of the instantaneous standard have also been observed in every month of year. Furthermore, violations of the fecal coliform standard Moore's Creek TMDL x occur during both dry and wet weather events. Therefore, the critical condition for fecal coliform bacteria in Moore's Creek is the typical hydrologic year. Special consideration will be given to the extremes of flow, including periods of very low flows and large storm events. Sources and Loading of Fecal Coiiform Bacteria Fecal coliform bacteria originate from all warm-blooded animals and can contaminate a stream from point and nonpoint sources. In the Moore's Creek watershed, fecal coliform bacteria are discharged from two point sources, the Moore's Creek Advanced Wastewater Treatment Plant, operated by the Rivanna Water and Sewer Authority, and Southwood Mobile Home park, which operates its own package treatment plant. The average fecal coliform concentration in the Moore's Creek Plant effluent is 17 cfu1100 ml, and the average volume of outflow is I 1 million gallons per day. This facility discharges just downstream from the state water quality monitoring site. The Southwood Mobile Home Park is located along Biscuit Run upstream of the water quality monitoring site. Poorly treated waste was observed around the outfall from the Southwood Mobile Home Park plant in February 2002, although there is no record of chronic permit violations from this plant. The plant has a permit limit of 200 cfu1100 ml and an average outflow of 39,000 gallons per day. The Virginia Department of Environmental Quality (VADEQ) water quality monitoring staff is currently investigating waste solids in the receiving stream near the outfall of Southwood. VADEQ will manage this problem through compliance assistance or enforcement. Nonpoint sources include background wildlife, livestock, pets, and humans. Major wildlife species are deer, geese, raccoons, muskrat, and beaver. Wildlife loads were applied to both the land surface and as direct input to the stream. Although agriculture is not intensive in the Moore's Creek watershed, cattle, horses, and goats contributed to the fecal coliform load to the land. In addition, cattle had access to the stream at two sites, where direct cattle loads to the stream can occur. Pet loads are dominated by dogs. Human nonpoint source loads come from failing septic systems, straight pipes to the stream, and leakage from sanitary sewers. A bacterial source tracking study concluded that the system was dominated by wildlife impacts, followed by livestock, While human Moore's Creek TMDL xi sources did not dominate the samples in the bacterial source tracking study, human bacteria were consistently detected. Modeling The BASINS Nonpoint Source Model (NPSM) and the Hydrologic Simulation Program - FORTRAN (HSPF) were used to simulate flow and the fate and transport of fecal coliform bacteria in the Moore's Creek watershed. These models incorporate temporal and spatial variability within the watershed. Due to a minimal amount of flow observations from Moore's Creek, an equivalent watershed approach and synthetic flow generation were used to calibrate the hydrological component of the models. The Buck Mountain Run watershed within the Rivanna drainage system was selected as an equivalent watershed. The HSPFINPSM model was calibrated to the Buck Mountain Run watershed, which is similar although a bit less developed than the Moore's Creek watershed, for the five-year period between 10/1992-9/1997. A synthetic flow generator that combined an artificial neural network and a maintenance of variance approach was developed and demonstrated on the Buck Mountain Run watershed. The synthetic flow generator was then applied to the Moore's Creek system to create flow predictions for the period over which significant water quality and flow observations exist (10/ 1996-8/2001). The synthetic flow predictions not only accurately reproduced the observed flows on Moore's Creek, but also provided a continuous calibration target for the NPSMIHSPF model on Moore's Creek. NPSMIHSPF parameters for the Buck Mountain Run watershed were adjusted to accurately reproduce the synthetic flows for the 5-year period. The water quality model was then calibrated to the observed fecal coliform concentrations over the same 5-year period. The fecal coliform loads that were applied directly to the stream and to the land surface were calculated on a monthly basis to account for seasonal variability in wildlife populations and the varying time that cattle will spend in the stream. Moore's Creek TMDL xii Results for Existing Conditions Water quality predictions during the calibration period predicted that under current conditions the instantaneous standard would be violated 18% of the time and the 30-day geometric mean criterion of 200 cfull00ml would be violated 62.8% of the time. Of the bacteria that reached the stream, 40.1 % were from wildlife, 34.1 % from livestock, 19.4% from dogs, and 6.4% from human sources, although the relative proportions of these sources may shin, dependent on whether the stream was at low or high flows and with season. Margin of Safety The fecal coliform load in the TMDL is divided into three categories. One is the margin of safety (MOS). A margin of safety will be explicitly added by achieving concentrations 5% below the 30-day geometric mean criterion of 200 cfu1100 ml. The remaining allowable 190 cfu1100ml is divided between the allowable loading from point sources (termed the waste load allocation, WLA) and the allowable loading from nonpoint sources (termed the load allocation, LA). TMDL Allocation Scenarios Establishment of a TMDL is meant to provide a loading that will be protective of water quality in the future. Thus, future conditions were used for determination of the allowable load. A human population increase and land use changes were assumed, consistent with the current population growth rate of the county and the county growth area plan. For the base case for future land -based nonpoint source loads, the fecal coliform loading rates (counts/acre/month) for most land uses were held constant with the rates from the current conditions. The exception was for grasslands, which included pastures. Due to a rapid decline in livestock populations, the loading rate used for grasslands during the calibration period was not representative of the anticipated loading in the future. Therefore, the loading rate for grasslands for the base case was modified to be consistent with the 2002 population and distribution of livestock within the watershed. Moore's Creek TMDL xiii Overall, the grassland loading rates under future conditions averaged 53% of those used during the calibration period. For the base case, future loads of coliform bacteria deposited directly in Moore's Creek will come from four sources: the two point sources and cattle and wildlife in the stream. Both point sources were modeled as discharging at their maximum permitted concentration of 200 cfu1100 ml and their expected average outflows. With the increase in population, the future average outflow from the Moore's Creek wastewater treatment plant increases to 15 million gallons per day, while the flow volume from Southwood facility remains unchanged. The direct load from cattle in stream was also reduced due to loss of livestock from one of the stream access areas. Wildlife deposition directly to the stream was assumed unchanged from that determined for the present case simulations. Although some modifications to the wildlife populations and distribution are expected to be induced by land use alterations, some wildlife populations will decrease while others will increase. Thus changes in wildlife numbers tend to offset, leaving only a small impact, relative to the model uncertainty, on the total wildlife load deposited directly in the stream. TMDL allocation scenarios were then generated by reducing the base case loads. The first step in building an allocation scenario was removal of all non -permitted human bacterial loads (straight pipes, sewer system leakage, and failing septic systems) and exclusion of cattle from the stream. These changes alone are insufficient to meet the TMDL goal. However, since untreated human waste should not be reaching the stream and allowing livestock access to the stream is an inappropriate management practice, these two steps were assumed in all other scenarios. Furthermore, adding extreme reductions in the remaining land -based loads from human activities was insufficient to meet the TMDL target. Therefore a TMDL allocation that reduced both the direct wildlife loads to stream and the remaining land -based nonpoint source loads was developed. Reduction levels varied by subwatershed and by land use. Table 1 shows the recommended load reductions to meet the TMDL goal. As in previous scenarios, all non -permitted human sources were removed and cattle were removed from the stream. Some subwatersheds show zero reductions in one or more of these sources simply because there were no such Moore's Creek TMDL xiv sources in the subwatershed under base case conditions. Residential reductions were assigned to developed subwatersheds along or near the main stem of Moore's Creek. Reductions in grassland loads were assigned to subwatersheds that still held significant numbers of livestock. The high percentage reduction to grasslands in subwatershed 9, assumes that the feral goat population will he removed and hest management practices will be put in place around the stockyard. For subwatersheds with a significant urban area, urban contributions were reduced from 45% to 50%, with the highest reductions assigned to the subwatersheds near the main stem of Moore's Creek.

The allocations are based on the total contributions to the stream. Each point source is allocated its permitted waste load allocation (WLA). The contribution from the Southwood Mobile Home Park (VA0029955) load, at 200 cfu/100 ml and an average outflow of 39,000 gallons/day, is shown under WLA(SW), while the contribution from the Moore's Creek Advanced Wastewater Treatment Plant (VA0025518) load, at 200 cfu1100 ml and an average flow of 15 million gallons per day, is shown under WLA(MC). These allocations require no reduction from the permitted point source loads, although any permit violations are assumed eliminated. Table 2 also Moore's Creek TMDL xv shows the total allocation to nonpoint sources (ILA) and the load reserved as a margin of safety (MOS). To meet this TMDL, the required reduction of all nonpoint source contributions (direct to stream and land based, human controlled and background) is 31.8% compared to current contributions or 34.6% compared to the base case future contributions. Table 2. was changed to reflect the inclusion of both bacteria Water Quality Standards (fecal and e. coli), accommodate the preexisting permitted pollutant waste load allocation, clarify the appropriate temporal units, and delineate and update the Future Growth.

Since the allocation assumes that the point sources are discharging at their maximum permitted levels, any excess load assigned to the point source takes away available loading from other sources. Thus, the reductions required from wildlife and the other nonpoint source land loads may need adjustment as staged implementation occurs and if monitoring data reflects obtainment of water quality standards. mplementation and Reasonable Assurance Section 303(d) of the Clean Water Act does not specify an implementation process for TMDLs. However, Virginia's 1997 Water Quality Monitoring, Information, and Restoration Act directs the VADEQ to develop a plan for the expeditious implementation of TMDLs. VADEQ plans to incorporate TMDL implementation plans as part of the Moore's Creek TMDL xvi 303(e) Water Quality Management Plans (WQMP). In a recent Memorandum of Understanding between the VADEQ and U.S. Environmental Protection Agency, the VADEQ has committed to updating the WQMPs. Thus, the WQMP will serve not only as a repository of TMDLs, but also maintain a record of the current progress on TMDL implementation plans. Each implementation plan will contain expected dates of achievement of water quality objectives, estimated costs, and a description of availability of funds for implementation of corrective actions. Implementation of the management plan to meet the TMDL will occur in stages. A potential Phase 1 goal could be reduction in the violations of the 30-day geometric mean criterion to less than 1 0% of the time. Removal of all straight pipes and any episodic permit violations at the Southwood Treatment plant would reduce the violations of the 30-day geometric mean standard to 5.0% of the time. Public Participation A community TMDL advisory committee was convened by the Thomas Jefferson Planning Disetrict Commission (TJPDC). Ultimately 12 people were named to the community advisory Committee by the TJPDC, including representatives from Albemarle County, the City of Charlottesville, the Rivanna Water and Sewer Authority, the Thomas Jefferson Soil and Water Conservation District, the Albemarle County Farm Bureau, the Southern Environmental Law Center, the Fry's Springs and Belmont Neighborhood Associations, and several other interested citizens. The community advisory committee met on September 21, 2001, November 27, 2001, February 12, 2002, and March 26, 2002. The advisory committee reviewed and provided feedback on the preliminary loading assumptions and on the final TMDL draft report. Their suggestions were incorporated into the loading assumptions during the calibration of the water quality model and into the final TMDL report. In addition, in compliance with the U.S. Environmental Protection Agency requirement for public participation, three public meetings were organized and conducted as part of the formal TMDL process. Public meetings were held in Charlottesville on June 7, 2001, November 15, 2001, and March 25, 2002. The first two meetings Moore's Creek TMDL xvii introduced and reviewed the current status of the TMDL development, while the third meeting presented the draft TMDL report. Watershed stakeholders will have opportunities to continue to provide input and participate in the development of implementation plans for the TMDL. Regional and local offices of the VADEQ and Virginia Department of Conservation and Recreation, along with other cooperating agencies, will continue to provide support during the plan development and implementation stages.

Discharges reportable to the department and the VSMP authority under the immediate reporting requirements of other regulations are exempted from this requirement. H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge including a "bypass" or "upset," as defined in this general permit, should occur from a facility and the discharge enters or could be expected to enter surface waters, the operator shall promptly notify, in no case later than within 24 hours, the department and the VSMP authority by telephone after the discovery of the discharge. 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 1 2. Unusual and extraordinary discharges include 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; Page 21 of 26 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 III 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 1 1 or 2 in writing as part of the SWPPP. The reports shall contain the information listed in Part 111 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. 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 Page 22 of 26 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 and other information. 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 III 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 III 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 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 shall 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: 5. "1 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 Page 23 of 26 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 coverage, 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 60 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. 0. 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. 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. Page 24 of 26 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 9VAC2.5-870-10, 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 Ill U 2 and 3. l►#21541 MT 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 ill 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. 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. Page 25 of 26 V. Upset. 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 fogs or other relevant evidence that: a. An upset occurred and that the operator can identify the cause 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: Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records shall be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that shall 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. Page 26 of 26 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. X. State permit actions. State permit coverage 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 permit coverage. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part I II 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 34 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 lags INSPECTION FREQUENCY: (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.
