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 HCI 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 All necessary Best Management Practices (BMP’s) will be in place and maintained in order to minimize dirt entering the storm systems. Primary strategies are as follows:  Avoid unnecessary site disturbance.  Maintain grading; install silt fences and sediment traps prior to any soil disturbance.  The installation of a tracking pad will be impractical due to the limited space available. Hansen will make sure that the short ramp into the excavation is kept as mud free as possible by use of screened rock over geo-textile fabric and not using the ramp in wet conditions.  The washout of concrete chutes will have to be done back into the concrete trucks due to the lack of space on site. Hansen will do everything they can to make sure that the concrete trucks do not wash out illegally offsite.  Hard plastic kiddie pools 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. 02/28/2019 P 970.920.1558 F 970.920.3038 P.O. Box 10493 Aspen, CO 81612 - 9 - 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. a. Proper facilities and procedures will be used for on-site waste storage and disposal. Daily inspection and maintenance of waste disposal areas will be conducted. Where possible, waste containers will be covered, and waste storage areas will be fenced. b. The contractor will ensure that good housekeeping will be employed during construction, with all work, materials storage and waste storage areas kept in a neat and orderly condition. c. Existing trees and mature vegetation that are not to be removed will be protected during construction to limit unnecessary disturbance of site soils and maintain natural erosion control. c) Materials Handling: a. All potentially hazardous materials will be stored off site. In the event that any such materials are stored on site, toxic materials and petroleum products 02/28/2019 P 970.920.1558 F 970.920.3038 P.O. Box 10493 Aspen, CO 81612 - 10 - will be enclosed and contained in an impervious elevated basin sized large enough to hold the volume of the hazardous materials being contained. b. Any spill or discharge or construction related materials will be cleaned up immediately and disposed of accordingly. c. Any spill not properly contained and cleaned-up will be reported to the proper authorities. i. Aspen Fire Department, Fire Marshal: 925-2690 ii.

City of Aspen Environmental Health Department: 920-5039. v. National Response Center: 800-424-8802 8.3 Final Stabilization and Long-Term Stormwater Quality All temporary BMPs will remain in place until construction is complete and revegetation has been verified to have taken hold. Final stabilization and long term stormwater quality are addressed by the civil and landscape drawings submitted as part of the building permit submittal package. 8.4 Inspection and Maintenance Procedures a) A thorough inspection of the stormwater management system will be performed at least every 14 days, and after any precipitation event that causes run off. The inspection will include the observation of the construction site perimeter and discharge points, all disturbed areas, and material storage areas exposed to precipitation. All erosion and sediment control measures will be inspected for integrity and functionality (e.g., sediment fences, hay bales, straw wattles, temporary swales and ditches). b) Damaged or ineffective BMPs will be fixed and/or replaced. Removed sediment will be placed where it will not become an additional pollution source. c) When necessary, BMPs will be added, removed or replaced with more effective measures. All such actions will be documented and the SWMP will be updated to reflect those changes. 9.0 FUGITIVE DUST CONTROL 9.1 Dust Control Plan The project’s Dust Prevention and Control Plan are as follows:  Avoid unnecessary site disturbance.  During construction a hose and spray nozzle will be used on exposed soils as necessary to mitigate air born dust. 02/28/2019 P 970.920.1558 F 970.920.3038 P.O. Box 10493 Aspen, CO 81612 - 11 -  Exported soils and other debris will be hauled off via covered dump trucks. All areas directly surrounding the site will be maintained daily with thorough cleanings taking place every Friday afternoon.  24 Hour Contact: Brian Robertson - 970.309.1954 10.0 EMISSIONS 10.1 Maintenance All vehicles and equipment used on site will be properly maintained such that the engines will function within the manufacture’s standards or parameters. 10.2 Opacity Emissions from diesel engines operated within the City of Aspen shall be of a shade or density no darker than 40% opacity, except for starting motion no longer than 10 seconds or for stationary operation not exceeding 10 seconds. 11.0 NOISE SUPPRESSION 11.0 General The noise limit at this site is 70 db during the summer season (6/1-Labor Day), 80 db all other times. The noise limit for construction is measured at the property line of the construction site. All construction equipment shall be adequately muffled and maintained to minimize project noise. The installation of noise barriers is the minimum technique to suppress noise, especially when jack hammering of concrete occurs. 11.1 Noise Suppression Plan All activity that generates noise in excess of 80 decibels requires a noise suppression plan and is restricted to operating between the hours of 9am and 5pm Monday through Friday. See Signed Noise Suppression Plan – APPENDIX D 11.2 Equipment and Methods In addition to the standard practices agreed to within the signed Noise Suppression Plan, the table below from the City of Aspen’s complete packet has been included for quick contractor/subcontractor reference. 02/28/2019 P 970.920.1558 F 970.920.3038 P.O.
