204.01 DESCRIPTION. This work consists of constructing and

maintaining temporary erosion control features shown on the plans or as directed. Coordinate installation of temporary erosion control features with construction of permanent erosion control features to the extent necessary to ensure economical, effective and continuous control of erosion and water pollution t hroughout the life of the contract. Develop and comply with a Storm Water Pollution Prevention Plan (SWPPP) approved by the Department in accordance with the Department’s Notice of Intent (NOI), and retain it at the site of the project for review during inspections. The SWPPP shall include the erosion control features as shown on the plans, or as directed, in addition to other required components of the SWPPP specified by the U. S. Environmental Protection Agency (EPA) and the Louisiana Department of Envir onmental Quality (LDEQ). The plan shall indicate the use of contract items and the coordination of this work with the scheduling of clearing and earthwork. Quality assurance requirements shall be as specified in the latest edition of the Department’s publ ication titled Application of Quality Assurance Specifications for Embankment and Base Course.

204.02 Control of Erodible Soil.

204.02.1 General: Prevent the transmission of soil particles into

streams, canals, lakes, reservoirs, or other waterways. Except as necessary for construction, do not deposit excavated material into streams or impoundments or in a position close enough to be washed into waterways by high water or runoff. Do not disturb lands or waters outside the limits of construction, except as authorized.

204.02.2 Adjacent to Waterways: Keep stream banks in their

natural state. Do not unnecessarily strip protective vegetation in the vicinity of stream banks. Conduct operations without damage to banks. Do not excavate banks except as shown on the plans or as otherw ise approved in writing. Work roads requiring bank cuts shall be approved by the project engineer prior to making such cuts. Restore the banks to the satisfaction of the project engineer. Temporary Erosion Control
