The WTP is located west of the City of Charlottesville in the town of Crozet. The Crozet Water Treatment Plant sources water from the Beaver Creek Reservoir. To meet DBP regulations, new carbon contactors containing granular activated carbon (GAC) will be added to the plant between the processes of filtration and primary disinfection. Construction of these improvements is anticipated to be completed by January 2017. Geographic coordinates of the project site are shown below Latitude IN) Longitude (W) 38°04'03.6"N -78°39'34.0"W Source: Google Maps The Crozet WTP resides within the jurisdiction of Albemarle County, and all necessary permits will be coordinated with the County. All proposed construction will take place within the Crozet WTP property; no construction will occur outside of the`property boundaries. The disturbed area for these improvements is approximately 0.94 acres. Any excess and unsuitable soil will be stockpiled onsite by the contractor with the option of unsuitable material to be disposed of in an approved location with all required permits to be acquired by the contractor. Erosion and sediment control measures will be used to limit erosion and contain sediment from the construction and cleared areas prior to the establishment of vegetation. PLAN ADMINISTRATION Copies of this SWPPP shall be kept on-site and be made available to the DEQ, or other regulatory agencies having authority, upon request. This SWPPP will also be available to all operators identified as having responsibilities to carry out provisions contained in this SWPPP. In addition, a copy of this document will be available at the Rivanna Water & Sewer Authority (RWSA) office. A copy of the permit coverage letter with the registration number for the construction activity, and the location where the SWPPP plan may be found and the name and telephone number of the contact person for scheduling viewing times will be posted conspicuously near the active portion of the construction site or a the main entrance as applicable. Access to these documents will be provided no less than once per month. FURTHER INFORMATION Further information and plan requirements for the SWPPP is found in the Erosion and Sedimentation Control Plan, and will be attached upon its approval (Appendix V). POLLUTION PREVENTION PLAN PURPOSE This Pollution Prevention Plan (PPP) has been developed as a requirement of the current Virginia Stormwater Management Program (VSMP) Permit VAR10 for Discharges of Stormwater from Construction Activities associated with the Crozet WTP GAC Upgrades Project. Implementation of the components of this PPP is required as a condition of the General Permit for Discharges of Stormwater from Construction Activities, Permit VAR10 which became effective July 1, 2014. The Department of Environmental Quality (DEQ) has been granted authority to administer the VSMP and is therefore the regulatory authority overseeing the implementation of this PPP. The PPP is also subject to all requirements of the Albemarle County Code Water Protection Ordinance (17-400). POTENTIAL POLLUTANT SOURCES Potential pollutant sources for this project include but may not be limited to the following: • Construction debris; • Water treatment facilities; • Litter; • Dust; • Oils/lubricants for equipment. CONTROL MEASURES FOR POTENTIAL POLLUTANT SOURCES Waste Disposal Any and all waste materials will be collected and stored in a securely lidded metal dumpster rented from a licensed solid waste management company. The dumpster shall meet all local and any State of Virginia solid waste management regulations. All trash and construction debris from the site will be deposited in the dumpster. The dumpster shall be emptied a minimum of once per week or more often if necessary. The trash will be hauled to a permitted solid waste disposal facility. No construction waste materials shall be buried onsite. All personnel will be instructed regarding the correct procedures for waste disposal. Notices stating these practices shall be posted in the office trailer and the superintendent on site shall be responsible for seeing that the procedures are followed. Any and all hazardous waste materials will be disposed of in the manner specified by the County of Albemarle, the City of Charlottesville and the State of Virginia Hazardous Waste regulations or by the manufacturer. Site personnel will be instructed in these practices and the superintendent on site shall be responsible for seeing that the procedures are followed. The Contractor shall control the management and disposal of liter from the site such that no adverse impacts to water quality occur. Dust Control and Off-Site Sediment If dust becomes a problem on the site, dust control measures must be implemented. A water truck shall be used to wet slopes and roadways as often as needed to control dust. Local ordinances shall be followed to ensure compliance with current water conservation measures. If sediment is being tracked offsite along the roadway, wash racks must be installed at locations where vehicles leave the site. Refer to the contractor drawings for all proposed location of temporary construction entrances and vehicle wash racks. Non-Storm Water Discharges Non-storm water discharges are prohibited from the site during the construction period. Any potential sources of non-storm water discharges must be identified by the Contractor and measures must be taken to ensure that these discharges do not leave the site. Existing, permitted, non-storm water discharges on the site are not impacted by the requirements of this Plan. Oils/Lubricants for Equipment Maintenance Any routine lubrication of construction equipment that will be performed on-site will be done only as needed and performed only by competent, authorized personnel. Equipment shall not be parked over or in the immediate vicinity of active storm drainage structures or drainage ways while performing this function. Any equipment with known petroleum product leakage shall be corrected prior to being mobilized to this site. Existing equipment already in use on this project shall be inspected daily and monitored by the project supervisor for leakage. Upon detection the supervisor shall immediately notify the Equipment Superintendent and a qualified mechanic shall be dispatched to correct the problem. In the event that a mechanic is not readily available, the equipment in question shall be removed from the site until repairs can be made or containment of all petroleum leakage ensured. Potential Contaminants It is not anticipated that storage of potential contaminants will take place on this project. Portable Sanitary Facilities During construction activities, portable sanitary facilities shall be located in such a manner as to protect the facilities from construction activities and to prevent the discharge from these facilities to the ground or to surface or ground waters. SPILL PREVENTION Good Housekeeping The following good housekeeping practices will be followed onsite during the grading operations: • An effort will be made to store only materials necessary to do the job, • All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers and, if possible, under a roof or other structure, , • Products will be kept in their original containers with the original manufacturer's label, • Substances will not be mixed with one another unless recommended by the manufacturer, • Whenever possible, all of a product will be used up before disposing of the container, • Manufacturer's recommendations for proper use and disposal will be followed, • The site superintendent will inspect daily to insure proper use and disposal of materials onsite, Hazardous Products These practices are used to reduce the risks associated with hazardous materials: • Products will be kept in original containers unless they are not re-sealable, • Original labels and material safety data will be retained; they contain important product information, • If surplus product must be disposed of, manufacturers or local and State recommended methods for proper disposal will be followed. Petroleum Products and Other Fluids Equipment utilized during construction activity on the site must be operated and maintained in such a manner as to prevent the potential or actual pollution of the surface or ground waters of the state. Fuels, lubricants, coolants, hydraulic fluids and any other petroleum products shall not be discharged onto the ground or into surface waters. Spent fluids shall be disposed of in a manner so as not to enter the waters, surface or ground, of the state and in accordance with applicable state and federal disposal regulations. Any spilled fluids shall be cleaned up to the extent practicable and disposed of in a manner so as not to allow their entry into the waters, surface or ground, of the state. All onsite vehicles will be monitored for leaks and receive regular preventative maintenance to reduce the chance of leakage. Petroleum products and other fluids will be stored in tightly sealed containers, which are clearly labeled. Herbicides, Pesticides and Fertilizers Herbicides, pesticides and fertilizer usage during the construction activity shall be consistent with the Federal Insecticide, Fungicide and Rodenticide Act and shall be in accordance with label restrictions. Fertilizers used will be applied only in the minimum amounts recommended by the manufacturer. Once applied, fertilizer will be worked into the soil to limit the exposure to storm water. Storage will be in a covered shed, if possible. The contents of any partially used bags of fertilizer will be transferred to a sealable plastic bin to avoid spills. 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: • Manufacturer's 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, • 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, dustpans, mops, rags, gloves, goggles, kitty litter, sand, sawdust, and plastic and metal trash containers specifically for this purpose, • All spills will be cleaned up immediately after discovery, • The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance, • Spills of toxic or hazardous material will be reported to the appropriate State or Local government agency, regardless of size, • The site superintendent responsible for the day-to-day site operations will be the spill prevention and cleanup coordinator. He will designate other site personnel who will receive spill prevention and cleanup training. These individuals will each become responsible for a particular phase of prevention and cleanup. The names of responsible spill personnel will be posted in the material storage area and in the office trailer onsite. - - . . ` CERTIFICATION "I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

K. Signatory requirements. 1. Registration statement.All registration statements shall be signed as follows: a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-making or decision-making functions for the corporation; or(ii)the manager of one or more manufacturing, production, or operating facilities, provided the manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for state permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures; b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or c. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this chapter, a principal executive officer of a public agency includes: (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency. 2. Reports, etc. All reports required by this general permit, including SWPPPs, and other information requested by the board or the department shall be signed by a person described in Part Ill K 1 or by a duly authorized representative of that person.A person is a duly authorized representative only if: a. The authorization is made in writing by a person described in Part 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 • General Permit No.: VAR10 Page 18 of 21 representative may thus be either a named individual or any individual occupying a named position); and c. The signed and dated written authorization is included in the SWPPP. A copy must be provided to the department and VSMP authority, if requested. 3. Changes to authorization. If an authorization under Part Ill 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 Ill K 1 or 2 shall make the following certification: "I certify under penalty of law that I have read and understand this document and that this document and all attachments were prepared in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this general permit may constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial of a state permit renewal application. The operator shall comply with effluent standards or prohibitions established under§ 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if this general permit has not yet been modified to incorporate the requirement. M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit after the expiration date of this general permit, the operator shall submit a new registration statement at least 90 days before the expiration date of the existing general permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing general permit. N. Effect of a state permit. This general permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state or local law or regulations. O. State law. Nothing in this general permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by§ 510 of the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U) and "upset" (Part III V), nothing in this general permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance. P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under§§62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law or§ 311 of the Clean Water Act. General Permit No.: VAR10 Page 19 of 21 Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances), which are installed or used by the operator to achieve compliance with the conditions of this general permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this general permit. R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering surface waters and in compliance with all applicable state and federal laws and regulations. S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of this general permit that has a reasonable likelihood of adversely affecting human health or the environment. T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this general permit. U. Bypass. 1. "Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part Ill U 2 and 3. 2. Notice. a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the date of the bypass. b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part III I. 3. Prohibition of bypass. a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may take enforcement action against an operator for bypass unless: (1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production; (2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and (3) The operator submitted notices as required under Part III U 2. General Permit No.: VAR10 Page 20 of 21 b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part III U 3 a. V. Upset. 1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology- based state permit effluent limitations if the requirements of Part III V 4 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review. 3. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 4. An operator who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: a. An upset occurred and that the operator can identify the cause(s)of the upset; b. The permitted facility was at the time being properly operated; c. The operator submitted notice of the upset as required in Part III I; and d. The operator complied with any remedial measures required under Part III S. 5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the burden of proof. W. Inspection and entry. The operator shall allow the department as the board's designee, the VSMP authority, EPA, or an authorized representative of either entity(including an authorized contractor), upon presentation of credentials and other documents as may be required by law to: 1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location. For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency. General Permit No.: VAR10 Page 21 of 21 X. State permit actions. State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition. Y. Transfer of state permits. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the Clean Water Act. 2. As an alternative to transfers under Part III Y 1, this state permit may be automatically transferred to a new operator if: a. The current operator notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property; b. The notice includes a written agreement between the existing and new operators containing a specific date for transfer of state permit responsibility, coverage, and liability between them; and c. The department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b. 3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site. Z. Severability. The provisions of this general permit are severable, and if any provision of this general permit or the application of any provision of this state permit to any circumstance, is held invalid, the application of such provision to other circumstances and the remainder of this general permit shall not be affected thereby.
