Proper disposal or management of all wastes and unused building material appropriate to the nature of the waste or material is required. 5.Public or private roadways shall be kept clear of accumulated sediment. All sediment that is cleared must be returned to the likely point of origin or other suitable location. Clearing of large amounts of sediment shall not include flushing the area with water. 6.Minimize the exposure of bare earth by limiting the work area to that necessary to perform the work, and by proper scheduling of manpower and equipment. 7.All erosion and sediment control measures shall be inspected, cleaned, and maintained following each storm event. 8.Wherever possible, maintain existing vegetative cover. Use non-vegetative material including mulch, erosion blankets, or stone to control erosion from disturbed areas. 9.A log shall be maintained of all inspections (weekly, and following storm events), maintenance and repair of erosion and sediment control measures. The log shall be maintained on site and be available upon request to the owners representatives and the operating authorities having jurisdiction over the site. 10.Once land disturbing activities begin, the following practices shall be provided: 10.1.The Trained Individual responsible for the erosions control maintenance for the contractor shall make weekly site inspections and after every rainfall event of 0.5 inches and greater. 10.2.Positive drainage shall be maintained at all times. Contractor shall ensure the downstream drainage system and adjacent properties are not receiving sediment/debris laden runoff. If additional measures are necessary to protect adjacent properties or the downstream drainage system, the Contractor shall notify the Engineer and implement the necessary measures immediately. 10.3.Once earth disturbing activities begin, the adjacent roadways, adjacent drives and parking lots shall be continuously monitored for sediment tracking. If sediment is found, immediate action is required to clean the offsite areas and the current erosion control practices will need to be inspected and modified accordingly to prevent any further sediment from leaving the project site. 10.4.Once the new storm structures and / or pipes are is in place, the appropriate type of inlet protection measures shall be placed. 10.5.As surface types change, perimeter silt protection may need to be modified or replaced with a different perimeter protection. Update and replace perimeter silt protection as needed and required per these plans and site conditions / restraints. 10.6.Continued monitoring of all exposed areas shall be performed in order to verify the surrounding areas are not becoming sediment laden from construction activities onsite. 10.7.As the construction occurs, disturbed areas shall be stabilized as soon as they are at finished grade or will be left bare for more than 15 days. 10.8.Provide final grade stabilization upon final grading of all areas including erosion control blanketing, seeding and sodding as appropriate. 10.9.Storm sewers that become silted due to construction activities shall be cleaned with a jet vacuum and the material properly disposed of. 10.10.As the existing swales and ditches are removed or graded away, the temporary check dams, filter dams, and sediment basins may be removed (unless noted otherwise on the plans) along with their retained debris, pollutants, and sediment. All material shall be disposed of off site at an approved location. 11.After site preparation, demolition, clearing and mass earthwork phases are complete and prior to infrastructure, building, and fine grading construction begins: 11.1.The perimeter erosion control practices (silt fence, construction entrance, check filter dams, temp. sediment basins, etc.) shall be examined, cleaned, and reinstalled if damaged. Some practices may need to be relocated or changed for the proposed site layout or per construction phases. (See Erosion Control Plans). 11.2.Relocate staging area if needed due to site configuration. 11.3.Install a Temporary Concrete Washout if not done already. 11.4.Once the new storm structures and / or pipes are is in place, the appropriate type of inlet protection measures shall be placed. 11.5.Continued monitoring of all exposed areas shall be performed in order to verify the surrounding areas are not becoming sediment laden from construction activities onsite. 11.6.As the construction occurs, disturbed areas shall be stabilized as soon as they are at finished grade or will be left bare for more than 15 days. 11.7.Provide final grade stabilization upon final grading of all areas including erosion control blanketing, seeding and sodding as appropriate. 11.8.Storm sewers that become silted due to construction activities shall be cleaned with a jet vacuumed and the material properly disposed of. 11.9.Temporary silt fence to be installed around pond and maintained until open areas contributing to direct sheet flow to pond have been stabilized. Only once these open areas are properly and permanently stabilized can this temporary silt fence be removed and disposed of properly. 11.10.Minimize erosion from exposed areas by providing and maintaining temporary or permanent stabilization measures. Erosion control measures to protect exposed areas shall be installed at the end of the day's work or within 24 hours of the completion of the earth disturbing activity, as applicable for the type of measure. 11.11.All disturbed areas shall be seeded and/or stabilized upon completion of the earth disturbing activity. 11.12.Rip-rap protection for final grades, detention ponds or storm sewers need established upon completion of final grading and storm sewer construction. 12.All graded areas (lawns, banks, mounds, etc.) with slopes equal to or steeper than 6h:1v shall be stabilized with an erosion control blanket unless noted otherwise. All constructed swales channels shall be stabilized with an erosion control blanket to the top of the bank. Soil stockpiles shall be seeded and mulched to minimize erosion. 13.All other lawn and planting areas shall be seeded and stabilized with an anchored, crimped or tackified mulch and seed mixture. 14.Areas to be paved shall be stabilized with a temporary stone cover. The temporary stone stabilization shall be equivalent to the proposed stone sub-base material. Adequate sub-base depths shall be maintained during construction, verified and restored, if necessary, prior to final paving. Stone stabilization shall be installed per the paving specifications and details. 15.Install pipe and grate inlet protection measures and pipe outlet protection as new pipes or pipe extensions are installed. Limit excavation to the work that can be performed that day. Trenches shall be seeded and mulched as part of the backfill operation. 16.Install inlet protection measures to prevent debris and sediment from entering storm system. Check weekly and after each storm event for debris and sediment. Clear blockages as identified. Damaged or ineffective measures shall be replaced. 17.Soil stockpiles shall have appropriate perimeter protection to prevent sedimentation of the surrounding acres. Any stock pile that will not be disturbed for 15 days or longer shall be seeded and protected with mulch or erosion control blanket. 18.All disturbed areas where work will potentially cease for 15 days or longer shall be seeded and stabilized immediately upon completion of the activity. 19.Erosion and sediment control measures shall be maintained until the site is 95% stabilized. 20.Construction Phase BMP's shall remain in place and continue to be inspected until the entire site has reached the minimum vegetative cover, 70% established. 21.Once construction is complete and prior to the contractor handing over the project to the owner, the contractor shall clean all debris, pollutants, and sediment from the storm sewers. 22.Once construction is complete and prior to the contractor handing over the project to the owner, the contractor shall clean all debris, pollutants, and sediment from the detention pond and remove the outlet structure rock check dam. Contractor to stabilize wet detention ponds (if any) after clean out. 23.Upon the site reaching the required minimum established vegetative cover, the IDEM CSGP Notice of Termination shall be submitted to the MS4 Department for approval prior to submitting it to IDEM if required for project.
