Stop work order and abandoned project are not solution to all the complaints, in fact it will be detrimental to the near by residents in the long run. <BR/>What TBRA should do is to pressure the state government to implement best management practices to reduce negative environmental impacts. <BR/><BR/>The goal of best management practices (BMPs) is to conduct all construction activities in a manner that effectively mitigates accelerated soil erosion, sediment movement and sediment <BR/>deposition offsite and also manages construction materials and wastes to prevent or minimize their potential runoff from the site. The BMPs selected shall meet all of the following standards: (The standards are copied from The City of Elko Construction Site Runoff Control Program )<BR/><BR/>1. Schedule construction activities to minimize the total amount of soil exposed at any given time. Preserve native vegetation to the maximum extent practicable and conduct clearing and grading only in areas necessary for building activities and equipment traffic. <BR/><BR/>2. Establish temporary or permanent stabilization practices on areas that have been disturbed as soon as practicable and no later than 14 days after construction activity in that portion of the site has temporarily or permanently ceased.<BR/><BR/>3. Protect slopes susceptible to erosion by tracking up and down slope and installing controls such as terraces, benches, retaining walls, temporary slope drains, fiber rolls, rolled erosion control products, and vegetation. <BR/><BR/>4. Design and construct all temporary and permanent facilities that convey water around or through disturbed areas with slopes and control measures that limit the flow of water to non-erosive velocities.<BR/>5. Protect waterways within and bordering the site by creating vegetative buffers and installing <BR/>temporary stream crossings. Protect natural drainages, storm drain channels and storm drain inlets in the vicinity of construction sites from disturbance, sedimentation and deposition of polluting materials such as construction site wastes. <BR/>6. Retain sediment caused by accelerated soil erosion from surface water before it leaves the site by installing sediment traps and/or perimeter controls such as temporary diversion dikes, <BR/>fiber rolls, or silt fences. <BR/>7. Remove sediment accumulated in BMPs within seven days after a runoff event, prior to the next forecasted rain event, or when BMP design capacity has been reduced by 50 percent or more, whichever occurs first. <BR/>8. Implement BMPs at construction site entrances and exits to control and minimize sediment deposition on paved roadways. <BR/><BR/>9. Do not store soil, aggregates, compost, construction materials or wastes on paved roadways. <BR/><BR/>10. Properly store construction site materials and manage wastes to prevent or minimize contact with storm water and transport offsite. Construction site materials include, but are not <BR/>limited to, petroleum products, paints, adhesives, and solvents. Construction site wastes include, but are not limited to, concrete washout, used paint supplies, sanitary waste, excess <BR/>construction materials, empty storage containers, and litter. <BR/><BR/>11. Properly manage vehicle and equipment fueling, maintenance, storage and parking areas to prevent and control leaks and spills. Properly manage the cleaning of vehicles and equipment to prevent the discharge of wash water and pollutants to the storm drain system, <BR/>natural drainages or watercourses. <BR/>12. Establish permanent stabilization on all bare soils with perennial vegetative cover and/or equivalent permanent stabilization measures upon completion of all site soil disturbing activities. Areas stabilized with vegetative cover must have a minimum density equivalent to 70 percent of the native background vegetative cover. <BR/><BR/>TBRA should make the following demands:<BR/>1)Tthe public display of topographic surveys, soils reports, hydrology reports and geotechnical analyses of affected hillside development.<BR/>2)The public display of critical areas identified at on-site areas which are subject to severe erosion, off-site areas which are especially vulnerable to damage from erosion and/or sedimentation, and areas of environmental concern must be identified and receive special attention.<BR/>3) Limit Time of Exposure - All land disturbing activity must be planned and conducted to limit exposure to the shortest feasible time.<BR/>4) Limit Exposed Areas - All land disturbing activity is to be planned and conducted to minimize the size of the area to be exposed at any one time.<BR/>5) Control Surface Water - Surface water runoff originating upgrade of exposed areas must be controlled to reduce erosion and sediment loss during the period of exposure.<BR/>6) Control Sedimentation - All land disturbing activity must be planned and conducted so as to prevent off-site sedimentation damage.<BR/>7)How Storm Water Runoff is being manage - When the increase in the velocity of storm water runoff resulting from a land disturbing activity is sufficient to cause accelerated erosion of the receiving watercourse, plans must include measures to control the velocity to the point of discharge so as to minimize accelerated erosion of the site and increased sedimentation of the stream.<BR/><BR/>Only when we force the state government to meet those demands, will the state government realise that it is ill prepared to handle hillside developments.Ong Eu Soon 王佑舜https://www.blogger.com/profile/12761206716238309124noreply@blogger.com
