The SWPPP must include, but not be limited to, an approved erosion and sediment control plan, an approved stormwater management plan, and this Pollution Prevention Plan (PPP) for regulated land disturbing activities, and a description of any additional control measures necessary to address a TMDL as applicable. The plan for implementing pollution prevention measures during construction activities developed on this sheet must be implemented and updated as necessary. Any PPP requirements not included on this sheet must be incorporated into the SWPPP required by 4VAC50-60-54 that must be developed before land disturbance commences. This PPP identifies potential sources of pollutants that may reasonable be expected to affect the quality stormwater discharges from the construction site (both on- and off-site activities) and describes control measures that will be used to minimize pollutants in stormwater discharges from the construction site. OTHER REFERENCED PLANS SWPPP requirements may be fulfilled by incorporating, by reference, other plans. All plans incorporated by reference become enforceable under the V SMP Permit Regulations and General Permit VAR10 for Discharges of Stormwater from Construction Activities. If a plan incorporated by reference does not contain all of the required elements of the PPP, the operator must develop the missing elements and include them in the SWPPP.

Modifications/revisions to the SWPPP shall include additional or modified control measures to address the identified deficiencies. If the necessary modifications/revisions require approval by the Administrator or DEQ, the modifications/revisions must be implemented no later than seven (7) calendar days following approval. If the necessary modifications/revisions do not require approval by the Administrator, the modifications/revisions must be implemented prior to the next anticipated storm event or as soon as practicable. SWPPP UPDATES The operator(s) shall update the SWPPP to include: ✓ 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; ✓ Documentation of modifications and revisions to the SWPPP; ✓ Areas that have reached final stabilization where no further SWPPP or inspection requirements apply; ✓ 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; and ✓ The date, volume, and corrective/preventative actions implemented for any prohibited discharge. The operator(s) shall update the SWPPP no later than seven (7) days following any of the situations identified above. OPERATOR INSPECTIONS The operator(s) identified below shall provide for inspections of the permitted land - disturbing activities by the qualified personnel identified below. The inspections will be conducted (select one the following options): at least once every four (4) business days; or ❑ at least once every five (5) business days and no later than '4$ hours following any measurable; storm_ event: Where areas are in a stabilized condition or runoff is unlikely due to winter conditions, the inspection frequency may be reduced to once every 30 days while these conditions exist. Otherwise, the operator(s) shall resume the regular inspection frequency identified above. The operator(s) shall provide for inspections of the permitted land -disturbing activity to ensure implementation and continued maintenance of all requirements of the Stormwater Pollution Prevention Plan (Erosion and Sediment Control Plan, Stormwater Management Plan, Pollution Prevention Plan, TMDL requirements, etc.). Records of the required inspections must be maintained and included in the SWPPP binder. The qualified personnel are encouraged to use the Operator Inspection form provided in the SWPPP binder to document the required inspections. If inspections are conducted once every five (5) business days and no later than 48 hours following any measureable storm event, the location of the rain gauge used to determine the amount of rain must be included in the SWPPP and documented in the inspection report. ACKNOWLEDGEMENTS I certify under penalty of law that the qualified personnel identified below: a. has been designated by the Operator to conduct inspections of the permitted site; b. is knowledgeable in the principles and practices of erosion and sediment control and stormwater management; C. possesses the skills to assess conditions at the permitted site for the Operator(s) that could impact stormwater quality and quantity; d. will assess the effectiveness of any erosion and sediment control measures or stormwater management facilities selected to control the stormwater discharges from the permitted site; and e. will conduct inspections in accordance with the frequency noted above in the OPERATOR INSPECTIONS section of this sheet. As the Operator(s) or Delegated Authority, I/we understand that prior to initiating land disturbance, the potential pollutant sources, appropriate control measures, and all responsible parties (operator, qualified inspection personnel, contractors, etc.) required as a condition of the General Construction Permit (GCP) and the Stormwater Pollution Prevention Plan (SWPPP) must be identified. I also understand this information must be updated as necessary throughout all phases of construction until the GCP is terminated. Furthermore, I/we certify under penalty of law that I/we have read and understand all requirements of the SWPPP (erosion and sediment control plan, stormwater management plan, pollution prevention plan, TMDL provisions, administrative requirements, etc.) and GCP and that the information herein 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 passibility of fine or imprisonment for knowing violations. Ilwe understand that I/we are ultimately responsible for compliance with all conditions and requirements of the SWPPP and GCP and for ensuring all contractors and subcontractors on the permitted site are aware of the conditions and requirements of the SWPPP and GCP. [/we shall comply with all conditions and requirements of the SWPPP and shall at all times properly operate and maintain all measures and control (and related appurtenances) which are installed or used to achieve compliance with the conditions of the GCP. Proper opration and maintenance also includes adequate funding and adequate staffing. Ilwe shall take all reasonable steps to minimize or prevent any discharge in violation of the SWPPP and/or GCP. I/we understand that if it determined by the Department of Environmental Quality (DEQ) in consultation with the State Water Control Board at any time that stormwater discharges are causing, have reasonable potential to cause, or contribute to and excursion above any applicable water quality standard, the DEQ may, in consultation with the Administrator, take appropriate enforcement action and require: a. Modification of control measures to adequately address water quality concerns; b. Submission of valid and verifiable data and information that are representative of ambient conditions and indicate that the receiving water is attaining water quality standards; or C. Cessation of discharges of pollutants from construction activity and submit an individual permit application according to 4VAC25-870-410. 9 f1 REVISIONS COUNTY COMMENTS MARCH 5, 2018 DATE October 5, 2017 SCALE N/A CONTOUR INTERVAL N/A • CC ' 0 .. f • JJ i Z• tt..
