Delivery vehicles and all other on-site vehicles will not be allowed to idle for more than five (5) minutes, with the exception of generators or PTO type operations. Project subcontractor and suppliers will be provided with written notification of Aspen’s vehicle idling regulations. See Section 13.08.110 Engine Idling – APPENDIX J. 6.5 Traffic Control Plan Contractor does not anticipate that there will be any need to interfere with traffic on any public right-of-way. If some unforeseen need arises, a Traffic Control Plan (TCP) will be prepared by a State Certified Traffic Control Supervisor. The plan will conform to the most current edition of the Manual of Uniform Traffic Control Devices for Streets and Highways (MUTCD) and be submitted to the City of Aspen Department of Engineering for approval/permitting. 8.0 SEDIMENT AND EROSION CONTROL 8.1 Storm Water Pollution Prevention Plan

due to the lack of space on site. Contractor will do everything they can to make sure that the concrete trucks do not wash out illegally offsite. • Hard plastic kiddie pools or concrete dumpsters will be used to protect the ground below the concrete pump transfer points. Spills captured will be allowed to dry and will be placed in the site trash receptacle. • Pathways around the house will be stabilized primarily through the use of screened rock over geo-textile fabric. 8.2 BMPs for Stormwater Pollution Prevention Best Management Practices (BMPs) will be employed for stormwater management as indicated in the following sections. The construction sequence as indicated in 4.3 above will help minimize the total area of disturbance at any particular point in time. a) Structural Practices: a. Silt fences will be installed on the downhill sides of all areas of disturbance as shown on the civil engineers drainage and erosion control plans. b. All open excavations will include the temporary development of a low point with a sump/pump for the removal of stormwater. The sump inlet will be protected with straw bales or a Dandy Bag type sediment filtration measure. Clear sump effluent will be discharged where it will not cause further erosion (to be determined based on construction phasing and available outlet areas at that time). c. Temporary diversion ditches and swales will direct runoff from other site areas through straw wattle and hay bale filtration prior to discharge off the site. The exact location and alignment of these structures will be determined in the field based on project phasing and the space needed for construction staging. d. Fugitive dust control will be achieved using a hose and spray nozzle. e. Surface roughening will be conducted in newly excavated areas to provide temporary stabilization when other temporary stabilization measures are not feasible (such as gravel or temporary vegetation) or will not be provided immediately. f. If for any reason construction is delayed for a period of time exceeding 30 days, more permanent stabilization will be put into place including backfilling open excavations and reestablishing vegetation with seed and mulch. b) Non-Structural Practices: Pollution prevention will be stressed among all employees and sub-contractors, including adequate training of personnel and frequent monitoring of activities.
