Reclamation shall include, but not be limited to, restoring the area so that it approximates natural contours; shaping and sloping the area to satisfy the requirements of subsection (a)(1); covering the area with clean fill to a minimum depth of two feet in order to allow for permanent stabilization and reclamation; and establishing a permanent vegetative ground cover; provided that the program authority may reduce the minimum depth of clean fill to one foot if the area is unlikely to be redeveloped. 5. The zoning administrator, or the program authority for those borrow, fill or waste areas subject to subsection (b), may require the owner to submit a reasonable performance bond with surety, cash escrow, letter of credit, any combination thereof, or such other legal arrangement acceptable to the county attorney, to ensure that measures could be taken by the county or the program authority at the owner's expense should he fail, after notice is given to perform required reclamation work specified in the notice. The amount of the bond or other surety shall be based on unit pricing for new public or private sector construction in Albemarle County, Virginia, and a reasonable allowance for estimated administrative costs and inflation which shall not exceed 25 percent of the estimated cost to initiate and complete the reclamation of the borrow, fill or waste area, and to comply with all other terms and conditions of the plan or narrative required by subsection (b). If reclamation work is required to be taken by the county or the program authority upon the failure of the owner to do so, the county or the program authority may collect the reasonable cost of the work direct) from the owner, to the extent that the cost exceeds the unex ended or unobli ated amount of the surety. Within Y P 9 Y 60 days after the reclamation work is completed and inspected and approved b the count engineer, the bond or other surety, or Y P P PP Y Y 9 Y� any unexpended or unobligated portion thereof, shall be refunded to the owner. b. If the aggregate area of a borrow, fill or waste activity will be greater than 10,000 square feet, then, as part of any permit issued pursuant to section 17-207 of the Code of Albemarle, the program authority shall first approve a plan or a narrative for such activity that satisfies the requirements of subsection (a) and the following: 1. All inert materials shall be transported in compliance with section 13-301 of the Code of Albemarle. Before a transporting vehicle leaves the parcel or parcels on which the borrow, fill or waste area is located it shall be cleaned so that no inert materials outside P P . of the vehicles load -bed can be deposited on a public street. 2. The borrow, fill or waste area and the access roads thereto shall be treated or maintained to prevent dust or debris from blowing or spreading onto adjacent properties or public streets. Depending on the anticipated intensity and duration of the activity and the P 9 J P P P P 9 P Y Y character of the development of adjoining properties, the program authority may require setback fencing and landscaping P J 9 P P P 9 Y Y q � 9 P 9 requirements as deemed appropriate, but which shall not exceed the requirements of sections 30.4.6, 30.4.7 and 30.4.9 of this chapter. 3. Borrow, fill or waste activity involving industrial -type power equipment shall be limited to the hours of 7:00 a.m. to 9:00 p.m., except in cases of a public emergency declared pursuant to section 2-1003 of the Code of Albemarle. 4.

The placement of fill or waste shall be completed within one year of its commencement except for reclamation activities and an P P Y � P Y other activities associated with the final stabilization of the area. The program authority may extend the date of completion upon the written request of the applicant, demonstrating that factors beyond the control of the applicant prevented the completion within the one-year period. The program authority may then extend the permit for a period of time that, in its sole discretion, is determined adequate to complete the work. 6. In lieu of a plan or narrative, the program authority may accept a contractual agreement between the Virginia Department of Transportation and its contractor for a public road project; provided that the program authority determines that the agreement satisfies at least to an equivalent extent the requirements and intent of this section.

The SWPPP shall be amended if, during inspections or investigations by the operator's qualified personnel, or by local, state, or federal officials, it is determined that the existing control measures are ineffective in minimizing pollutants in discharges from the construction activity. Revisions to the SWPPP shall include additional or modified control measures designed and implemented to correct problems identified. If approval by the VESCP authority, VSMP authority, or department is necessary for the control measure, revisions to the SWPPP shall be completed no later than seven calendar days following approval. Implementation of these additional or modified control measures shall be accomplished as described in Part II H. Page 12 of 26 3. The SWPPP shall clearly identify the contractors that will implement and maintain each control measure identified in the SWPPP. The SWPPP shall be amended to identify any new contractor that will implement and maintain a control measure. 4. The operator shall update the SWPPP as soon as possible but no later than seven days following any modification to its implementation. All modifications or updates to the SWPPP shall be noted and shall include the following items: a. A record of dates when: (1) Major grading activities occur; (2) Construction activities temporarily or permanently cease on a portion of the site; and (3) Stabilization measures are initiated; b. Documentation of replaced or modified controls where periodic inspections or other information have indicated that the controls have been used inappropriately or incorrectly and were modified; c. Areas that have reached final stabilization and where no further SWPPP or inspection requirements apply; d. All properties that are no longer under the legal control of the operator and the dates on which the operator no longer had legal control over each property; e. The date of any prohibited discharges, the discharge volume released, and what actions were taken to minimize the impact of the release; f. Measures taken to prevent the reoccurrence of any prohibited discharge; and g. Measures taken to address any evidence identified as a result of an inspection required under Part II G. 5. Amendments, modifications, or updates to the SWPPP shall be signed in accordance with Part III K. D. Public notification. Upon commencement of land disturbance, the operator shall post conspicuously a copy of the notice of coverage letter near the main entrance of the construction activity. For linear projects, the operator shall post the notice of coverage letter at a publicly accessible location near an active part of the construction project (e.g., where a pipeline crosses a public road). The operator shall maintain the posted information until termination of general permit coverage as specified in Part I F. E. SWPPP availability. 1. Operators with day-to-day operational control over SWPPP implementation shall have a copy of the SWPPP available at a central location on -site for use by those identified as having responsibilities under the SWPPP whenever they are on the construction site. Page 13 of 26 The operator shall make the SWPPP and all amendments, modifications, and updates available upon request to the department, the VSMP authority, the EPA, the VESCP authority, local government officials, or the operator of a municipal separate storm sewer system receiving discharges from the construction activity. If an on -site location is unavailable to store the SWPPP when no personnel are present, notice of the SWPPP's location shall be posted near the main entrance of the construction site. The operator shall make the SWPPP available for public review in an electronic format or in hard copy. Information for public access to the SWPPP shall be posted and maintained in accordance with Part II D. If not provided electronically, public access to the SWPPP may be arranged upon request at a time and at a publicly accessible location convenient to the operator or his designee but shall be no less than once per month and shall be during normal business hours. Information not required to be contained within the SWPPP by this general permit is not required to be released. F. SWPPP implementation. The operator shall implement the SWPPP and subsequent amendments, modifications, and updates from commencement of land disturbance until termination of general permit coverage as specified in Part I F. All control measures shall be properly maintained in effective operating condition in accordance with good engineering practices and, where applicable, manufacturer specifications. If a site inspection required by Part II G identifies a control measure that is not operating effectively, corrective actions shall be completed as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority, to maintain the continued effectiveness of the control measures. If site inspections required by Part II G identify an existing control measure that needs to be modified or if an additional or alternative control measure is necessary for any reason, implementation shall be completed prior to the next anticipated measurable storm event. If implementation prior to the next anticipated measurable storm event is impracticable, then additional or alternative control measures shall be implemented as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority. G. SWPPP Inspections. 1. Personnel responsible for on -site and off -site inspections. Inspections required by this general permit shall be conducted by the qualified personnel identified by the operator in the SWPPP. The operator is responsible for ensuring that the qualified personnel conduct the inspection. 2. Inspection schedule. a. For construction activities that discharge to a surface water identified in Part II B 5 and B 6 as impaired or having an approved TMDL or Part I B 7 as exceptional, the following inspection schedule requirements apply: (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 24 hours following a measurable storm event. In the event that a measurable storm event occurs when Page 14 of 26 there are more than 24 hours between business days, the inspection shall be conducted on the next business day; and (2) Representative inspections as authorized in Part II G 2 d shall not be allowed. b. Except as specified in Part II G 2 a, inspections shall be conducted at a frequency of: (1) At least once every five business days; or (2) At least once every 10 business days and no later than 24 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 24 hours between business days, the inspection shall be conducted on the next business day. C. Where areas have been temporarily stabilized or land -disturbing activities will be suspended due to continuous frozen ground conditions and stormwater discharges are unlikely, the inspection frequency described in Part II G 2 a and 2 b may be reduced to once per month. If weather conditions (such as above freezing temperatures or rain or snow events) make discharges likely, the operator shall immediately resume the regular inspection frequency. d. Except as prohibited in Part II G 2 a (2), representative inspections may be utilized for utility line installation, pipeline construction, or other similar linear construction activities provided that: (1) Temporary or permanent soil stabilization has been installed and vehicle access may compromise the temporary or permanent soil stabilization and potentially cause additional land disturbance increasing the potential for erosion; (2) Inspections occur on the same frequency as other construction activities; (3) Control measures are inspected along the construction site 0.25 miles above and below each access point (i.e., where a roadway, undisturbed right-of-way, or other similar feature intersects the construction activity and access does not compromise temporary or permanent soil stabilization); and (4) Inspection locations are provided in the inspection report required by Part II G. e. If adverse weather causes the safety of the inspection personnel to be in jeopardy, the inspection may be delayed until the next business day on which it is safe to perform the inspection. Any time inspections are delayed due to adverse weather conditions, evidence of the adverse weather conditions shall be included in the SWPPP with the dates of occurrence. 3. Inspection requirements. a. As part of the inspection, the qualified personnel shall: (1) Record the date and time of the inspection and, when applicable, the date and rainfall amount of the last measurable storm event; Page 15 of 26 (2) Record the information and a description of any discharges occurring at the time of the inspection or evidence of discharges occurring prior to the inspection; (3) Record any land -disturbing activities that have occurred outside of the approved erosion and sediment control plan; (4) Inspect the following for installation in accordance with the approved erosion and sediment control plan, identification of any maintenance needs, and evaluation of effectiveness in minimizing sediment discharge, including whether the control has been inappropriately or incorrectly used: (a) All perimeter erosion and sediment controls, such as silt fence; (b) Soil stockpiles, when applicable, and borrow areas for stabilization or sediment trapping measures; (c) Completed earthen structures, such as dams, dikes, ditches, and diversions for stabilization and effective impoundment or flow control; (d) Cut and fill slopes; (e) Sediment basins and traps, sediment barriers, and other measures installed to control sediment discharge from stormwater; (f) Temporary or permanent channels, flumes, or other slope drain structures installed to convey concentrated runoff down cut and fill slopes; (g) Storm inlets that have been made operational to ensure that sediment laden stormwater does not enter without first being filtered or similarly treated; and (h) Construction vehicle access routes that intersect or access paved or public roads for minimizing sediment tracking; (5) Inspect areas that have reached final grade or that will remain dormant for more than 14 days to ensure: (a) Initiation of stabilization activities have occurred immediately, as defined in 9VAC25-880-1; and (b) Stabilization activities have been completed within seven days of reaching grade or stopping work; (6) Inspect for evidence that the approved erosion and sediment control plan, "agreement in lieu of a plan," or erosion and sediment control plan prepared in accordance with department -approved annual standards and specifications has not been properly implemented. This includes: Page 16 of 26 (a) Concentrated flows of stormwater in conveyances such as rills, rivulets, or channels that have not been filtered, settled, or similarly treated prior to discharge, or evidence thereof; (b) Sediment laden or turbid flows of stormwater that have not been filtered or settled to remove sediments prior to discharge; (c) Sediment deposition in areas that drain to unprotected stormwater inlets or catch basins that discharge to surface waters. Inlets and catch basins with failing sediment controls due to improper installation, lack of maintenance, or inadequate design are considered unprotected; (d) Sediment deposition on any property (including public and private streets) outside of the construction activity covered by this general permit; (e) Required stabilization has not been initiated or completed or is not effective on portions of the site; (f) Sediment basins without adequate wet or dry storage volume or sediment basins that allow the discharge of stormwater from below the surface of the wet storage portion of the basin; (g) Sediment traps without adequate wet or dry storage or sediment traps that allow the discharge of stormwater from below the surface of the wet storage portion of the trap; and (h) Land disturbance or sediment deposition outside of the approved area to be disturbed; (7) Inspect pollutant generating activities identified in the pollution prevention plan for the proper implementation, maintenance, and effectiveness of the procedures and practices; (8) Identify any pollutant generating activities not identified in the pollution prevention plan; and (9) Identify and document the presence of any evidence of the discharge of pollutants prohibited by this general permit. 4. Inspection report. Each inspection report shall include the following items: a. The date and time of the inspection and, when applicable, the date and rainfall amount of the last measurable storm event; b. Summarized findings of the inspection; c. The locations of prohibited discharges; d. The locations of control measures that require maintenance; Page 17 of 26 e. The locations of control measures that failed to operate as designed or proved inadequate or inappropriate for a particular location; f. The locations where any evidence identified under Part II G 3 a (6) exists; g. The locations where any additional control measure is needed; h. A list of corrective actions required (including any changes to the SWPPP that are necessary) as a result of the inspection or to maintain permit compliance; i. Documentation of any corrective actions required from a previous inspection that have not been implemented; and The date and signature of the qualified personnel and the operator or its duly authorized representative. 5. The inspection report shall be included into the SWPPP no later than four business days after the inspection is complete. The inspection report and any actions taken in accordance with Part II shall be retained by the operator as part of the SWPPP for at least three years from the date that general permit coverage expires or is terminated. The inspection report shall identify any incidents of noncompliance. Where an inspection report does not identify any incidents of noncompliance, the report shall contain a certification that the construction activity is in compliance with the SWPPP and this general permit. The report shall be signed in accordance with Part III K of this general permit. H. Corrective actions. The operator shall implement the corrective actions identified as a result of an inspection as soon as practicable but no later than seven days after discovery or a longer period as approved by the VSMP authority. If approval of a corrective action by a regulatory authority (e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control measures shall be implemented to minimize pollutants in stormwater discharges until such approvals can be obtained. The operator may be required to remove accumulated sediment deposits located outside of the construction activity covered by this general permit as soon as practicable in order to minimize environmental impacts. The operator shall notify the VSMP authority and the department as well as obtain all applicable federal, state, and local authorizations, approvals, and permits prior to the removal of sediments accumulated in surface waters including wetlands. Page 18 of 26 PART III CONDITIONS APPLICABLE TO ALL VPDES PERMITS NOTE: Discharge monitoring is not required for this general permit. If the operator chooses to monitor stormwater discharges or control measures, the operator shall comply with the requirements of subsections A, B, and C, as appropriate. A. Monitoring. 1. Samples and measurements taken for the purpose of monitoring shall be representative of the monitoring activity. Monitoring shall be conducted according to procedures approved under 40 CFR Part 136 or alternative methods approved by the U.S. Environmental Protection Agency, unless other procedures have been specified in this general permit.

This period of retention shall be extended automatically during the course of any unresolved litigation regarding the regulated activity or regarding control standards applicable to the operator, or as requested by the board. C. Reporting monitoring results. Page 19 of 26 The operator shall update the SWPPP to include the results of the monitoring as may be performed in accordance with this general permit, unless another reporting schedule is specified elsewhere in this general permit. Monitoring results shall be reported on a discharge monitoring report (DMR); on forms provided, approved or specified by the department; or in any format provided that the date, location, parameter, method, and result of the monitoring activity are included. If the operator monitors any pollutant specifically addressed by this general permit more frequently than required by this general permit using test procedures approved under 40 CFR Part 136 or using other test procedures approved by the U.S. Environmental Protection Agency or using procedures specified in this general permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the DMR or reporting form specified by the department. 4. Calculations for all limitations which require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in this general permit. D. Duty to provide information. The operator shall furnish, within a reasonable time, any information which the board may request to determine whether cause exists for terminating this general permit coverage or to determine compliance with this general permit. The board, department, EPA, or VSMP authority may require the operator to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of surface waters, or such other information as may be necessary to accomplish the purposes of the CWA and the Virginia Stormwater Management Act. The operator shall also furnish to the board, department, EPA, or VSMP authority, upon request, copies of records required to be kept by this general permit. E. Compliance schedule reports. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of this general permit shall be submitted no later than 14 days following each schedule date. F. Unauthorized stormwater discharges. Pursuant to § 62.1-44.5 of the Code of Virginia, except in compliance with a state permit issued by the department, it shall be unlawful to cause a stormwater discharge from a construction activity. G. Reports of unauthorized discharges. Any operator who discharges or causes or allows a discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance or a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117, 40 CFR Part 302, or § 62.1-44.34:19 of the Code of Virginia that occurs during a 24-hour period into or upon surface waters or who discharges or causes or allows a discharge that may reasonably be expected to enter surface waters, shall notify the Department of Environmental Quality of the discharge immediately upon discovery of the discharge, but in no case later than within 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted to the department and the VSMP authority within five days of discovery of the discharge. The written report shall contain: 1. A description of the nature and location of the discharge; 2. The cause of the discharge; Page 20 of 26 3. The date on which the discharge occurred; 4. The length of time that the discharge continued; 5. The volume of the discharge; 6. If the discharge is continuing, how long it is expected to continue; 7. If the discharge is continuing, what the expected total volume of the discharge will be; and Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present discharge or any future discharges not authorized by this general permit. 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. 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 III 1 2. 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 II I 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 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. 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. 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 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. 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. 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 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 shall be kept under the conditions of this general permit; 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 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 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. 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.

Site Map: A site map/vicinity map is provided on the ESC Plan attached Description of The site consists of single family detached residential lots with an existing pond on the south of the Existing property. Site Conditions: Offsite Land All offsite activities that send fill material to this property shall be covered under a separate ESC Disturbance: permit 7 Sea uence of Maior Activities: 1. Schedule pre construction meeting with Albemarle County 2. Identify limits of disturbance and tree protection 3. Install temporary construction entrances 4. Install perimeter erosion control devices 5. Complete site construction 6. Temporary Seed and mulch as necessary 7. Stabilize Site & Demobilize Name of Receivine Waters: Rivanna River -Carroll Creek (HUC 020802040404 (JR17)) DEQ staff has determined that the proposed land -disturbing activity will discharge to a surface water identified as impaired or for which a TMDL wasteload allocation has been established and approved prior to the term of the general permit for (i) sediment or a sediment -related parameter or (ii) nutrients. Therefore, the following general permit (Part I.B.4) and SWPPP requirements (Part H.A.5) must be implemented for the land -disturbing activity: • Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is reached on any portion of the site. • Nutrients (e.g. fertilizers) shall be applied in accordance with manufacturer's recommendations or an approved nutrient 00management plan and shall not be applied during rainfall events. • Inspections shall be conducted at a frequency of (i) at least once every four (4) business days or (ii) at least once every five (5) business days and no later than 24 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 24 hours between business days, the inspection shall be conducted on the neat business day. • Representative inspections used by utility line installation, pipeline construction, or other similar linear construction activities shall inspect all outfalls. Special Conditions Related to TMDLs: Albemarle County is in the process of developing action plans for the Chesapeake Bay TMDL and for two local TMDLs having a waste load allocation and approved by the Virginia Soil and Water Conservation Board. TMDLs pollutants of concern Approval date Chesapeake Bay phosphorus, nitrogen, N/A and sediment Rivanna River mainstem, North Fork of the Rivanna e, Coli bacteria 1/5f2009 River, Meadow Creek, and Beaver Creek Rivanna River benthic / sediment 6/11/2008 Above sources have been identified in the Albemarle County MS4 Program Plan (2013-2018) dated October of 2014. Endaneered and Threatened Species and Critical Habitat Protection The United States Fish & Wildlife Service has identified species that are believed to or known to occur in Virginia. The list can be found on their Environmental Conservation Online System at: http://ecos.fws. og v/ecpO/reports/species-listed-by-state-report?state=VA&status=listed There are no known endangered or threatened species located within the project site. Erosion and Sediment Controls: Approved erosion and sediment control plans are incorporated by reference as part of this Stormwater Pollution Prevention Plan. Approved plans are included in this S WPPP binder. Stabilization Practices: 1. The purpose of the erosion control measures shown on these plans shall be to preclude the transport of all waterborne sediments resulting from construction activities from entering onto adjacent properties of state waters. If field inspection reveals the inadequacy of the plan to confine sediment to the project site, appropriate modifications will be made to correct any plan deficiencies. In addition to these notes, all provisions of the Virginia Erosion and Sediment Control Regulations shall apply to this project. 2. All erosion and sediment control measures shall be installed and maintained in accordance with the Virginia Erosion and sediment Control Handbook (31 Edition, 1992) and Virginia Regulations VR 625-02-00 Erosion and Sediment control Regulations. The contractor shall be thoroughly familiar with all applicable measures contained therein which may be pertinent to this project. 3. All points of construction ingress and egress shall be protected by a temporary paved construction entrance, with a wash rack, to prevent tracking of mud onto public right-of-ways. An entrance permit from VDOT is required prior to any construction activities within state right-of-ways. Where sediment is transported onto a public road surface, the road shall be thoroughly cleaned at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individual subdivision lots as well as to larger land disturbing activities. 4. The Albemarle County Department of Community Development schedules the pre -construction meeting; therefore, the developer, project engineer, or contractor must contact the Albemarle County Department of Community Development in order to schedule a preconstruction meeting. The preconstruction meeting shall be held at the Albemarle County Office Building between the County, the developer, the project engineer, and the contactor prior to issuance of the land disturbing permit. The contractor shall submit a sequence of construction to the County for approval prior to the preconstruction meeting. The contractor will supply code compliance with the name of the individual who will be responsible for any maintenance of installed measures that is required. The SWPPP Inspector will be in contact with this person to ensure that the necessary maintenance of the installed measures is taking place on a daily basis. The Albemarle County Department of Community Development must be notified one week prior to the preconstruction conference, one week prior to the commencement of land disturbing activity, and one week prior to the final inspection. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times. 6. Sediment basins and traps, perimeter dikes, sediment barriers, and other measures intended to trap sediment onsite must be constructed as a first step in grading and be made functional before upslope land disturbance takes place. Earthen structures such as dams, dikes, and diversions must be seeded and mulched immediately after installation. Periodic inspections of the erosion control measures shall be made to assess their condition. Any necessary maintenance of the measures shall be accomplished immediately upon notification by the SWPPP Inspector and shall include the repair of measures damaged by any subcontractor including those of the public utility companies. 7. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion and sedimentation as determined by the plan approving authority. 8. All disturbed areas are to drain to approved sediment control measures at all times during all land disturbing activities and during site development until final stabilization is achieved. 9. Sediment control measures may require minor field adjustments at time of construction to insure their intended purpose is accomplished. Division of code compliance approval will be required for other deviations from the approved plans. 10. Surface flows over cut and fill slopes shall be controlled by either redirecting flows from traversing slopes or by installing mechanical devices to safely lower water down slope without causing erosion. A temporary fill diversion (std. 3.09 and spec. 3.10) can be installed prior to the end of each working day. 11. During dewatering operations, water will be pumped into an approved filtering device. 12. The contractor shall place soil stockpiles at the locations shown on the SWPPP plan sheet for each area of construction, or as directed by design engineer. Soil stockpiles shall be stabilized or protected with sediment trapping measures immediately. Offsite waste or borrow areas shall be approved by the division of code compliance prior to the import of any borrow or export of any waste to or from the project. 13. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not limited to, offsite borrow or waste areas), the contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving authority. 14. The contactor shall complete drainage facilities within 30 days following completion of rough grading at any point within the project. The installation of drainage facilities shall take precedence over all underground utilities. Outfall ditches from drainage structures shall be stabilized immediately after construction of same. This includes installation of erosion control stone or paved ditches where required. Any drainage outfalls required for a street must be completed before street grading or utility installation begins. 15. Permanent or temporary soil stabilization must be applied to all denuded areas within 7 days after final grade is reached on any portion of the site. Soil stabilization must also be applied to denuded areas which may be a final grade but will remain dormant (undisturbed) for longer than 14 days. Soil stabilization measures include vegetative establishment, mulching and the early application of gravel base material on areas to be paved. 16. No more than 300 feet of sanitary storm sewer, waterlines, or underground utility lines are to be immediately stabilized (i.e., the same day). 17. If disturbed area stabilization is to be accomplished during the months of November, December, January or February, stabilization shall be accomplished by permanently seeding the area with a seeding mixture that includes the seasonal nurse crop for the Piedmont area, which is Winter Rye. See Table 3.32-D for a list of site specific seeding mixtures for the Piedmont area. This is in accordance with Specification 3.32 from the Virginia Erosion and Sediment Control Handbook (VESCH). The seeding area will also need to be mulched in order to assist the growth of the seeding in the winter months (Specification 3.35 of the VESCH). For temporary seeding stabilization during these months, a 50150 mix of annual ryegrass and winter ryegrass, as well as a mulching cover should be put down according to Specification 3.31 of the VESCH, Table 3.31-B. 18. The term seeding, final vegetative cover or stabilization, on this plan shall mean the successful germination and establishment of a stable grass cover from a properly prepared seedbed containing the specified amounts of seed, lime, and fertilizing in accordance with Specification 3.32, permanent seeding. Irrigation shall be required as necessary to ensure establishment of grass cover. 19. All slopes steeper than 3:1 shall require the use of erosion control blankets such as Excelsior blankets to aid in the establishment of a vegetative cover that is hardier than grass. Matting or mulch matting may also be used on recently planted slopes in order to protect the seeding until the vegetative cover becomes established on the slopes. Installation shall be in accordance with Specification 3.35, mulching and manufacturer's instructions. No slopes shall be created steeper than 2:1. 20. Inlet protection in accordance with Specification 3.07 shall be provided for all storm drain inlets as soon as practical following construction of same. 21. 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. Trapped sediment and disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. 22. If Applicable- As -built drawings must be provided for all detention/BMP facilities. Also upon completion, the construction of all detentionBMP facilities shall be certified by a professional engineer who inspected the structure during construction. The certification shall state that to the best of his/her judgment, knowledge, and belief, the structure was constructed in accordance with the approval plans and specifications. Structural Practices: The following erosion and sediment control structural practices will be incorporated on the project sites: 1. Construction Entrance 2. Construction Road Stabilization 3. Safety Fence 4. Silt Fence 5. Temporary Diversion Dikes 6. Temporary Right -of -Way Diversion 7. Temporary Sediment Traps 8. Temporary Sediment Basin 9. Outlet Protection 10. Dust Control 11. Permanent/Temporary Seeding 12. Storm Drain Inlet Protection 13. Riprap 14. Tree Preservation and Protection Waste Materials: All waste materials will be collected and stored in a proper receptacle in accordance with all local and State solid waste management regulations. All trash and construction debris from the site will be deposited in dumpsters. The trash will be hauled to an appropriate waste disposal site. No construction waste materials will be buried onsite. All project personnel will be instructed regarding the correct procedure for waste disposal. Hazardous Waste: All hazardous waste materials will be disposed of in the manner specified by the manufacturer and as required by local or State regulation. Site personnel will be instructed in these practices. Sanitary Waste: All sanitary waste will be collected from the portable units as required by local and State regulation. Offsite Vehicle Tracking: Stabilized construction entrances will be provided to help reduce vehicle tracking of sediments. The paved street adjacent to the site entrance will be swept as needed to remove any excess mud, dirt or rock tracked from the site. Dump trucks hauling material from the construction site will be covered with a tarpaulin. Timine of Controls and Measures: As indicated in the Stabilization Practices, pennanent or temporary soil stabilization must be applied to all denuded areas within 7 days after final grade is reached on any portion of the site. Soil stabilization must also be applied to denuded areas which may not be a final grade but will remain dormant (undisturbed) for longer than 30 days. Soil stabilization measures include vegetative establishment, mulching and the early application of gravel base material on areas to be paved. Certification of Compliance with Federal, State and Local Requirements: The Stormwater Pollution Prevention Plan reflects State requirements for stormwater management and erosion and sediment control, as established in the Virginia Stornwater Management Handbook and Virginia Erosion and Sediment Control Manual. Maintenance and Inspection Procedures: Inspections of the construction site shall be made by the SWPPP Inspector or by other qualified members of the Pollution Prevention Team. Erosion and sediment control measures identified in the plan shall be observed to ensure that they are still operating correctly. The contractor shall inspect all erosion control measures at least once every 4 or 5 business days and after each significant rainfall producing event. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shall be made within seven (7) days. Inspections shall be conducted (i) at least once every four (4) business days or (ii) at least once every five (5) business days and no later than 24 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 24 hours between business days, the inspection shall be conducted on the next business day. These inspections shall cover disturbed areas that have not been finally stabilized, areas used for storage of materials that are exposed to precipitation, structural control measures, and locations where vehicles enter or exit the site. Where areas have been finally or temporarily stabilized or runoff is unlikely due to winter conditions (e.g. site is covered with snow, ice or frozen ground exists) such inspections shall be conducted at least once every month. If weather conditions (such a above freezing temperatures or rain/snow events) make discharges likely, the operator shall immediately resume the regular inspection frequency. Reports summarizing each inspection shall be retained onsite as part of this Stormwater Pollution Prevention Plan. Each inspection report shall include the following items: a) The date and time of the inspection and when applicable, the date and rainfall amount of the last measurable storm event b) Summarized findings of the inspection c) The location(s) of prohibited discharges d) The location(s) of controlled measures that require maintenance e) The location(s) of control measures that failed to operate as designed or proved inadequate or inappropriate for a particular location f) The location(s) where any evidence identified under Park II G3a(7) exists g) The location(s) where any additional control measure is needed that did not exist at the time of inspection h) A list of corrective actions required (including nay changes to the SWPPP that are necessary) as a result of the inspection or to maintain permit compliance i) Documentation of any corrective actions required from a previous inspection that have not been implemented j) The date and signature of the qualified personnel and the operator or its duly authorized representative in accordance with Part III K of the general permit Recordkeepine I. Corrective Action and Forms The operator shall implement the corrective action(s) identified as a result of an inspection as soon as practicable but no later than seven days after discovery or a longer period as approved by the VSMP authority. If approval of a corrective action by a regulatory authority (e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control measures shall be implemented to minimize pollutants in stormwater discharges until such approvals can be obtained. The operator may be required to remove accumulated sediment deposits located outside of the construction activity covered by this general permit as soon as practicable in order to minimize environmental impacts. The operator shall notify the VSMP authority and the department as well as obtain all applicable federal, state, and local authorizations, approvals, and permits prior to the removal of sediments accumulated in surface waters including wetlands. The contractor shall be responsible for the installation and maintenance of all erosion and sediment control practices and for corrective actions. Corrective action notes can be found directly on the SWPPP reports. H. Grading and Stabilization Activities Log Information on when major grading activities occur and when construction activities temporarily or permanently ceases on a portion of the site will be provided on the inspection reports for the project provided in the SWPPP updates section or on the grading and stabilization log provided in the appendix. III. Rainfall Tracking A blank rainfall data chart can be found in the appendix. It will be placed in the SWPPP notebook bi-monthly. IV. Log of Changes to the SWPPP The operator shall amend the SWPPP whenever there is a change in the design, construction, operation or maintenance that has a significant effect on the discharge of pollutants to surface waters and that has not been previously addressed in the SWPPP. A log of any changes to the SWPPP is provided in the appendix. Comprehensive Site Compliance Evaluation — Post Construction: Facility inspections will be conducted at least once a year by qualified personnel. The inspections will assess conditions at the facility that could impact stormwater quality and to assess the effectiveness of the BMPs that were constructed to control the quality of the stormwater discharges. Non-Stormwater Discharees: It is expected that the following non-stormwater discharges will occur from the site during the construction period. I. Waters used to wash vehicles or equipment where soaps, solvents, or detergents have not been used and the wash water has been filtered, settled, or similarly treated prior to discharge. 2. Water used to control dust that has been filtered, settled, or similarly treated prior to discharge. 3. Potable water sources, including uncontaminated waterline flushing's/fire flow analysis. 4. Routine external building wash down where soaps, solvents or detergents have not been used and the wash water has been filtered, settled, or similarly treated prior to discharge. 5. Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (or where all spilled or leaked material has been removed prior to washing); where soaps, solvents, or detergents have not been used; and where the wash water has been filtered, settled, or similarly treated prior to discharge. 6. Foundation or footing drains where flows are not contaminated with process materials such as solvents. 7.

Training includes discussions of spill response, good housekeeping, and other material management practices. Employee training generally occurs with each new employee once hired by the site contractor. (b) Good Housekeeping: The following good housekeeping practices will be followed onsite during the construction project. 1. All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers. Materials which have the potential for contaminating runoff during storm events will be stored in their appropriate watertight containers, stored under a canopy, tarpaulin, shrink wrapped or otherwise precluded from direct exposure of precipitation. 2. Empty containers that may contain chemical residues shall be disposed of in accordance with State and Local regulations. 3. Products, where possible, will be kept in their original containers with the original manufacture's label. 4. Chemical or petroleum products will not be mixed with one another unless recommended by the manufacturer. 5. Whenever possible, all of a product will be used up before disposing of the container. 6. Manufacturer's recommendations for proper use and disposal will be followed. 7. The site superintendent will inspect daily to ensure proper use and disposal of materials onsite. IV. Hazardous Products: These practices are used to reduce the risk associated with hazardous materials. 1. Products will be kept in original containers unless they are not resealable. 2. Original specimen labels and materials safety data sheets will be kept on file; they contain important product information. If surplus product must be disposed of, manufacturers and/or local and State recommended methods for proper disposal will be followed. Material Safety Data Sheets (MSDS) will be available for all chemical materials used onsite and will be located with the SWPPP binder. V. Product Specific Practices: The following product specific practices will be followed onsite: (a) Petroleum Products: 1. All onsite vehicles will be monitored for fluid leaks and will receive regular preventive maintenance to reduce the chance of leakage. 2. It is recommended that, if practicable, all refueling, repair and changing of equipment and vehicle fluids shall be conducted in a designated area, with the use of either spill buckets and/or fuel spill mats to reduce the potential for contamination. This area will be designed in a manner to reduce the potential for contamination of onsite resources. For refueling, repair and changing of equipment and vehicle fluids outside of the designated areas, care should be taken to avoid activities within +/- 50 feet of wetlands, streams, water bodies, tree preservation areas or any other environmentally sensitive areas. 3. Petroleum products will be stored in tightly sealed containers which are clearly labeled. 4. An area will be designated for the collection and storage of all chemical and storage of all chemical and petroleum based products and containers for those products. The containers shall be protected from rain events. These areas are identified on the SWPPP/PPP Reference Drawing included with the "Final Construction Plans" for each block. 5. Any asphalt substances used onsite will be applied according to the manufacturer's recommendations. 6. The project superintendent will regularly inspect the site to insure proper disposal methods of used antifreeze, oils, filters and other hazardous materials are followed. (b) Fertilizers: Fertilizers used will be applied according to manufacturer's product standards. The contents of any partially used bags of fertilizer will be transferred to a sealable plastic container to avoid spills. (c) Paints: All containers will be tightly sealed and stored when not required for use. Excess paint will be properly disposed of according to manufacturers' instructions or State and local regulations. (d) Concrete Tracks: Concrete trucks will only wash out or discharge surplus concrete or drum wash water at approved locations in accordance with State and local regulations. These areas are identified on the SWPPP/PPP Reference Drawing included with the "Final Construction Plans" for each block. VI. Spills and Leaks: This section normally contains a list of significant spills and significant leaks of toxic or hazardous pollutants that occurred at areas that are exposed to precipitation or that otherwise drain to a stormwater conveyance at the facility within the 3 year period immediately prior to the date of submission of a registration statement to be covered under this permit. No significant spills and/or leaks have occurred at the site of toxic or hazardous pollutants at areas that are exposed to precipitation. VIL Spill control Practices: In addition to the good housekeeping and material management practices discussed in the previous sections of this plan, the following practices will be followed for spill prevention and cleanup: 1. Manufacturers' recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. 2. Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and materials may include but not be limited to brooms, dust pans, mops, rags, gloves, goggles, absorbent material (e.g. kitty litter, sand, sawdust) and plastic and metal trash containers. 3. All spills will be cleaned up immediately after discovery. 4.
