Show ENGINEERING E. CONTROLS Controls to prevent release of contaminants off-site shall be addressed in this section. Also to be addressed are the final grading, contouring, erosion controls, and re vegetation of the Site. Methods for dust suppression from the trucks (tarping , wet loads) and from the roadways, shall be addressed. This requirement also includes retention or necessary stilling basins to mitigate recontamination of the channel from upper reaches that may not be addressed during the construction season. . DUST SUPPRESSION Methods of dust transportation, 2. control to be' used during excavation, and placement of soil must be addressed. EROSION CONTROL 'Methods of completion monitoring erosion both control, during and after of the Removal, must be addressed. Long term of erosion control methods must also be addressed. ,3 • The FINAL CONTOURING channel be to ensure the re-e,stablished appropriate capacity using standard methods of open channel design. The Site shall be recontoured to meet with existing nativ:e ground contours, and to minimize erosion due to air and'water action. During construction must control be maintained, with grade engineering those measures surveying. Generally, only necessary to ensure the stability of the channel will be required and' no wo,rk additional such as replacement of existing must flow , culverts related to routine flood control measures wil be required. , . F. 4. RE-VEGETATION Methods of ,re-vegetation for the final configuration on the site shall be addressed The mixture of seed to be used. for vegetation shall approved by the EPA. ,be SAMPLING and ANALYSIS/TESTING PROCEDURES' Sampling and analysis will be necessary to fulfill the Soil sampling will be requirements of the respon'se. necessary to delineate perimeter areas for' excavation, defining the depth and lateral extent of contamination and The respondents must determine the similar objectives. potential for leaching of hazardous substances from the 7 _ |
