70 Series 600 Erosion and Sediment Control

71 Sediment and Erosion Control Standards General All construction work performed in the United States, no matter how large or how small, must be performed in a way that minimizes the amount of soil, sediment and other pollutants introduced into local storm water sewers and waterways. This is required by the Environmental Protection Agency s Clean Water Act. Local government agencies, such as the City of Springfield, and Greene County, have jurisdiction on enforcing these regulations, as does the Missouri Department of Natural Resources and the Army Corps of Engineers. All work performed by or for City Utilities of Springfield must comply with these regulations. There are many tools and construction methods used to prevent pollution caused by construction runoff, which are commonly known as Best Management Practices, or BMP s. The Construction Standards included in this Section are intended to provide instruction on how to use the most common BMP s currently available. However, it is the employee or contractor s responsibility to ensure these BMP s are effective. If the BMP s in place are not effectively preventing soil runoff pollution, you are responsible for developing a plan that is effective. The City of Springfield has developed a more comprehensive booklet of BMP s, which should be referenced if the common methods described in these Standards are not entirely effective on your project. Large construction projects, effecting more than 1 acre, require a Storm Water Pollution Prevention Plan, or SWPPP. This is required to obtain a land disturbance permit from the City or County. Engineers and Designers are encouraged to incorporate these Standards as part of their SWPPP. Similarly, on smaller construction projects effecting less than 1 acre of land, these same BMP s must be utilized to prevent erosion and sediment pollution to the storm water sewers and waterways in the area. Erosion control measures will be both temporary and permanent in nature. Temporary controls will include such items as compost filter socks, silt fencing, mulching, and ditch checks. Permanent controls will consist of rip-rap placement and reestablishing permanent cover (asphalt, gravel, vegetation). It should be noted that the BMPs standards should be used for the appropriate situations as determined by the project engineer on permitted projects, or by the personnel overseeing the construction activities for non-permitted projects. BMPs installed shall be maintained and monitored throughout construction and until ground cover has been reestablished. Stormwater runoff from or over disturbed areas consists of both sheet flow and concentrated flow. A great deal of storm water runoff will be in the form of sheet flow, therefore, many of the erosion control practices will be employed to control erosion of this type. Concentrated flow may occur within small intermittent drainage paths located along the right-of-ways or along drainage ditches parallel to roadways. Natural vegetation can act as an effective filter media to remove silt from surface runoff. The use of natural vegetation is the most cost effective means of sediment control and generally results in the least overall disturbance to the land. This technique should be applied wherever appropriate given site conditions. Sediment barriers will be required in areas where natural vegetation alone is inadequate to minimize sediment transport from the area of disturbance.. Throughout the course construction activity, roadways, parking lots and other hard surfaces should be cleaned of spilled or tracked soil and gravel on at least a daily basis. Cleaning will consist of scraping with backhoe bucket followed by sweeping. It is the responsibility of the construction supervisor to determine if the services of the City street sweeper are required to clean roadways.

72 All disturbed areas should be restored as soon as practicable to minimize erosion and sediment transport. All aspects of the construction should proceed to completion in an efficient and timely fashion. This will also be of economic benefit to the City Utilities. Planning and Selection of BMPs Proper planning will help to identify potential erosion problems before they occur. The project engineer and/or construction supervision shall be responsible for surveying the entire project site prior to work commencing in order to select the appropriate BMPs given site conditions.. The phasing of the work shall be considered in this planning phase to ensure BMP s are installed at the appropriate time and locations corresponding with the construction activity. Some key items to consider while planning the erosion and sediment controls for the project are as follows: Asses direction and grade of all slopes to evaluate the natural drainage of the site Identify areas where sheet flow or concentrated flow will occur Note location, type and number of storm water inlets Recognize all streams, creeks, dry-creeks, rivers, ponds, and lakes near the site Note previously eroded areas, steep slopes, or bare areas that will be susceptible to erosion Select appropriate measures that will minimize sediment from leaving the jobsite or reaching the watershed system. Revaluate measures periodically and maintain them to ensure they are functioning as expected Installation of BMPs Utilizing the BMP standards in this section, construct the BMPs necessary to minimize erosion for the utility construction project. The materials to be used in constructing BMP s are available from City Utilities storeroom (see appendix A), or through a blanket contract with Eroco (see appendix B). Materials not on hand may also be purchased from local vendors as necessary. Maintaining BMPs Inspecting and maintaining the construction site and the BMPs installed are vital to the performance of all erosion and sediment control measures. If a particular BMP is not functioning as desired it is the responsibility of construction supervision to make necessary changes. BMPs such as curb inlet protection, silt fences, etc. will need sediment cleaned periodically from them to ensure they continue to function as they should. Accumulated silt will be removed when it reaches a depth of ½ the height of silt socks or curb inlet protection. Accumulated silt will be removed from behind silt fences when it accumulates to a depth of six inches. The silt will be removed and disposed of on the job site in a manner that will not contribute to additional siltation. After rain falls of ½ or greater, the construction site should be inspected to ensure BMP s functioned properly and to determine if additional sediment or erosion control practices are needed. When soil disturbing activities cease in an area for more than 14 days, the disturbed areas shall be protected from erosion by stabilizing the area with mulch, or other similarly effective erosion control BMPs. If the slope of the area is greater than 3:1 the disturbed areas shall be protected from erosion by stabilizing the area with mulch or other similarly effective erosion control BMPs if activities cease from more than seven days. Removal of BMPs Temporary BMPs shall be removed from the construction site once non-erodible permanent cover has been installed and/or established. This will typically be through seeding, mulching, sodding, paving, etc.
