MANAGEMENT OF EROSION, SEDIMENTATION, AND STORM WATER POLLUTION PREVENTION

220.01 Description

This work consists of overseeing the construction and maintenance of erosion and sediment control measures, in accordance with these specifications, in compliance with the details shown in the Contract, and as approved by the Resident Engineer. The purpose of this work is to minimize or elim inate air pollution and pollution of rivers, streams, impoundments, and private properties from the discharge of dust and/ or storm water associated with construction activity. Below is a listing of terms and definitions as they apply to these specificatio ns: Authorization to Discharge. The document issued from ODEQ , as a result of the NOI application, serving as the official notification of the site specific permit. BMPs (Best Management Practices) . A wide range of project management practices, schedules, activities, or prohibition of practices, that when used alone or in combination, prevent or reduce erosion, sedimentation, and/or pollution of adjacent properties, water bodies, and wetlands. BMPs include temporary or permanent structural and nonstructura l devices and practices. Completion Date. See Subsection 101.05, "Definitions," or Subsection 105.17, “Project Completion and Acceptance.” Erosion. The detachment and movement of soi l particles from their original location by force of water, wind, ice, and gravity. MANAGEMENT OF EROSI ON, SEDIMENTATION, AND STORM WATER POLLUTION PREVENTION 220.01 Erosion Control. Erosion control reduces the potential of soil particles from being detached by the use of soil stabilizing practices. These practices are noted in the SWM P and SWPPP . Final Stabilization. A point in time when all earth -disturbing activities are complete and permanent erosion and sediment controls are established and functional. The stabilized site is protected from erosive forces of raindrop impact and wat er flow. Typically, all unpaved areas except graveled shoulders, crushed aggregate base course, or other areas not covered by permanent structures are protected by either a uniform blanket of perennial vegetation (at least 70 percent of native background cover as found in the undisturbed surrounding area) or equivalent stabilization measures including but not limited to riprap, geotextiles, gabions or paved ditches. NOI (Notice of Intent). The OPDES General Permit application form to commence earth -disturb ing activities for storm water discharges on projects which have earth disturbing activities of 1 acre or more. NOT (Notice of Termination). The OPDES General Permit application form indicating the end of earth -disturbing activities and the attainment of Final Stabilization . OPDES. Oklahoma Pollutant Discharge Elimination System Act. ODEQ. Oklahoma Department of Environmental Quality. ODEQ/OPDES General Permit. The General Permit for Storm Water Discharges from Construction Activities, issued by the ODEQ under the OPDES regulations. It requires a SWPPP before earth -disturbing activities for the project. ODEQ is the regulatory, enforcement and permitting authority for the Environmental Protection Agency (EPA) in the State of Oklahoma. Sediment Control. Sediment control minimizes detached particles from leaving the site or entering a water body by the use of structural practices. These practices are noted in the SWMP and SWPPP . Sedimentation. Sedimentation occurs when the eroded particles are deposited in a new location. SPRP (Spill Prevention and Response Plan). The Contractor’s detailed plan for prevention of pollution that stems from the use, containment, cleanup, and disposal of hazardous material, including petroleum products generated by construction activities and the use of construction equipment. SWMP (Storm Water Management Plan) . The Department ’s general plan for control of project -related Erosion and Sedimentation . It is developed by the Department and included in the Contract documents. It se rves as a resource for bid estimation and a framework from which the Contractor develops the project SWPPP . The SWMP normally consists of the following:  SWMP Information Sheet;  Site Specific Erosion and Sediment Control Plan Sheets;  Summary of Disturbed A reas Draining to a Common Outfall  Contract Pay Items with Plan Notes;  Summary of Temporary and Permanent Erosion and Sediment Controls; and  Site Specific Drainage Map.

220.04 Management of Erosion, Sedimentation, and Storm Water Pollution Prevention

SWPPP (Storm Water Pollution Prevention Plan). The Contractors plan for erosion and sediment control and storm water management under the OPDES General Permit . The SWPPP is developed by incorporating pertinent information supplied by the Department ( SWMP ) with the Contractors’ information and describi ng site -specific controls and management of issues identified for the project based upon construction sequences and activities. See specific requirements in Subsection 220.04.C, "Contractor Responsibilities for SWPPP ."

220.02 Materials
