HomeMy WebLinkAboutWPO201500083 Plan - E&S Erosion Control Plan 2016-02-02Purpose of This Minor Amendment 1. The purpose of this Minor Amendment is to relocate the Storm Water Management Basin. The original Storm. Water Management Basin could not be installed due to existing monitoring wells in that location. The original Minor Site Plan Amendment was approved on February 1, 2007'. 2. The limits of this Minor Amendment are shown on Sheets C-800. 8. For purposes of storm water calculations the existing conditions shown on this plan are what were in place prior to construction of improvements shown on original Minor Site Plan Amendment. 4. The total area of disturbance for this minor amendment is 1.25 acres.

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 Pp 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 pians incorporated by reference become enforceable under the VSMP 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.

Various controls and/or measures designed to prevent and/or minimize pollutants in stormwater discharges from the project site must be applied to the sources found on the site.
