(c) Notwithstanding this article and in accordance with the Virginia Erosion and Stormwater Management Act, Article 2.3 (§ 62.1-44.15:24 et seq.) of Chapter 3.1 of Title 62.1 of the Code of Virginia, the following activities are required to comply with the soil erosion control requirements but are not required to comply with the water quantity and water quality technical criteria, unless otherwise required by federal law: (1) Activities under a state or federal reclamation program to return an abandoned property to an agricultural or open land use; (2) Routine maintenance that is performed to maintain the original line and grate, hydraulic capacity, or original construction of the project. The paving of an existing road with a compacted or impervious surface and reestablishment of existing associated ditches and shoulders shall be deemed routine maintenance if performed in accordance with this subsection; and (3) Discharges from a land -disturbing activity to a sanitary sewer. Sec. 11.1-8 Stormwater pollution prevention plan; contents of plans. (a) A stormwater pollution prevention plan (SWPPP) shall include, but not be limited to, an approved erosion and sediment control plan, an approved stormwater management plan, a pollution prevention plan for regulated land -disturbing activities, and a description of any additional control measures necessary to address a TMDL pursuant to subsection (d) of this section. (b) A soil erosion control and stormwater management (ESM) plan consistent with the requirements of VESMA and regulations must be designed and implemented during construction activities. Prior to land disturbance, this plan must be approved by the city in accordance with the VESMA, this article, and attendant regulations. (c) A pollution prevention plan that identifies potential sources of pollutants that may reasonably be expected to affect the quality of stormwater discharges from the construction site and describe control measures that will be used to minimize pollutants in stormwater discharges from the construction site must be developed before land disturbance commences. (d) In addition to the requirements of subsections (a) through (c) of this section, if a specific wasteload allocation for a pollutant has been established in an approved TMDL and is assigned to stormwater discharges from a construction activity, additional control measures must be identified and implemented by the operator so that discharges are consistent with the assumptions and requirements of the wasteload allocation. (e) The stormwater pollution prevention plan must address the following requirements as specified in 40 CFR 450.21, to the extent otherwise required by state law or regulations and any applicable requirements of a state permit: (1) Control stormwater volume and velocity within the site to minimize soil erosion; (2) Control stormwater discharges, including both peak flow rates and total stormwater volume, to minimize erosion at outlets and to minimize downstream channel and stream bank erosion; (3) Minimize the amount of soil exposed during construction activity; (4) Minimize the disturbance of steep slopes; (5) Minimize sediment discharges from the site. The design, installation and maintenance of erosion and sediment controls must address factors such as the amount, frequency, intensity and duration of precipitation, the nature of resulting stormwater runoff, and soil characteristics, including the range of soil particle sizes expected to be present on the site; (6) Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas to increase sediment removal and maximize stormwater infiltration, unless infeasible; (7) Minimize soil compaction and, unless infeasible, preserve topsoil; Page 14 of 27
