required toxicity testing information in accordance with the E& SC Manual to the Engineer for review and acceptance prior to using any chemical treatment on the project site . 104-6 .5 Removal of Temporary Erosion Control Features : In general, remove or incorporate into the soil any temporary erosion control features existing at the time of construction of the permanent erosion control features in an area of the project in such a manner that no detrimental effect will result . The Engineer may direct that temporary features be left in place . 104-6 . 6 Signed and Sealed As-Built Drawings : Prior to final acceptance of the project, submit to the Engineer three copies of as-built drawings and a certified survey verifying the as . built conditions for all installed and constructed surface water management systems . The as -built drawings and certified survey must satisfy all the requirements and special conditions listed in the Water Management District ' s Environmental Resource Permit (ERP ) and any applicable local permit . The as -built drawings and certified survey must be signed and sealed by an appropriately licensed professional registered in the State of Florida. If the ERP does not contain specific requirements , provide as -built drawings with the following information as a minimum . 1 . Discharge structures : structure identification number, type , locations (latitude and longitude) , dimensions and elevations of all , including weirs , bleeders , orifices , gates , pumps , pipes , and oil and grease skimmers . 2 . Side bank and underdrain filters , or exfiltration trenches : locations , dimensions and elevations of all, including clean-outs , pipes, connections to control structures and points of discharge to receiving waters . 3 . Storage areas for treatment and attenuation : storage area identification number, dimensions , elevations , contours or cross- sections of all , sufficient to determine stage - storage relationships of the storage area and the permanent pool depth and volume below the control elevation for normally wet systems . 4 . System grading : dimensions , elevations , contours , final grades or cross - sections to determine contributing drainage areas , flow directions and conveyance of runoff to the system discharge points . 5 . Conveyance : dimensions , elevations , contours , final grades or cross - sections of systems utilized to divert off- site runoff around or through the new system . 6 . Water levels : existing water elevations and the date determined . 7 . Benchmarks : location and description (minimum of one per major water control structure) . 1044 Maintenance of Erosion and Sediment Control Features . 104-7 . 1 General : Provide routine maintenance of permanent and temporary erosion and sediment control features , at no expense to the Department, until the project is complete and accepted. If reconstruction of such erosion and sediment control features is necessary due to the Contractor ' s negligence or carelessness or, in the case of temporary erosion and sediment control features , failure by the Contractor to install permanent erosion control features as scheduled, the Contractor shall replace such erosion control features at no expense to the Department . If reconstruction of permanent or temporary erosion and sediment control features is necessary due to factors beyond the control of the Contractor, the Department will pay for replacement under the appropriate Contract pay item or items . Inspect all erosion and sediment control features at least once every seven calendar days and within 24 hours of the end of a storm of 0 . 50 inches or greater.
