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. Contractor 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. 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 BM Ps 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 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 This will require a I (to be determined based on construction phasing and available outlet areas de-watering permit at that time). from the State of r C.

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. RECEIVED 03/27/2019 - 8 - P 970.309.1836 211 Cottonwood Ln Aspen,Co 8161\tpEN BUILDING DEPARTMENT 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 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.

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 RECEIVED 03/27/2019 - 9 - P 970.309.1836 211 Cottonwood Ln Aspen,Co 8161\tpEly BUILDING DEPARTMENT 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. • Exported soils and other debris will be hauled off via covered dump trucks.

I understand that if any construction activities exceed 80 decibels and are not covered by this document I will contact the City of Aspen Environmental Health Department to design a specific noise suppression plan for those activities. Samuel T Barney Signature Print name On-site Contact Phone # (970) 309-1836 Many activities on construction sites are noisy. Although some noise may be unavoidable, it can often be controlled using improved work practices. Builders should make all reasonable efforts to minimize noise. Noise Suppression plans are required for all construction projects where activities will generate noise that exceeds 80 decibels. Section 18.04.050(A)(2)(d) Hours of operation All construction activity is limited to the following days and times: Monday thru Friday Saturday Sunday 7:30 am to 5:30 pm 9:00 am to 5:00 pm No construction work is allowed Constructions activities producing noise greater than 80 decibels are limited to the following days and times: Monday thru Friday 9:00 am to 5:00 pm Work that is over 80 decibels which by law requires a noise suppression plan will not be allowed for Saturday work that includes but not limited to the use of compressors, generators, jackhammers, power equipment, nail guns, drilling machinery, earth moving equipment and similar loud construction activities. This does not restrict quiet work inside and outside that does not require a power source, including a battery, on Saturday. Construction activity is not allowed during all federal holidays. Due to the congestion in Aspen when town is completely full, noise suppression plans will not be approved for the following dates: Christmas Week (December 25 through Jan. 1), Food and Wine Week in June (Friday thru Sunday), 4th of July day and/or weekend if it falls on a Friday or Monday, and Labor Day weekend. RECEIVED Revised 1/08/2013 0 3/2 7/2 019 ASPEN BUILDING DEPARTMENT Specific noise suppression requirements for all activities exceeding 80 decibels at a construction site include: 1. Notify neighbors within two hundred fifty (300) feet of the project informing them of the kinds of equipment, expected noise levels and durations of loud work. Including the variation of noise levels during a typical construction days may be helpful. Such notification must be in writing and be done seven (7) days prior to the starting time of the project. Communication with neighbors can prevent complaints from arising, and resolve concerns before there is a problem. Provide a phone number where the foreman can be reached prior to the start of the job. 2. Operate equipment in accordance with manufacturer's specifications and with all standard manufacturers' mufflers and noise-reducing equipment in use and in properly operating condition. 3. Post notices to inform workers, including sub-contractors, about the basic noise requirements, as well as specific noise restrictions, to the project. 4. Install noise barriers around all equipment/activities specified in Table 1: TYPICAL CONSTRUCTION EQUIPMENT REQUIRING NOISE SUPPRESSION. Noise barriers not only significantly reduce construction noise, but they also provide an extra benefit of `hiding" the noise producing sources, thus increasing a neighbor's tolerance. (See also the attached list of noise blocking methods for details on approved noise barriers.) 5. Move portable loud equipment including generators, compressors, and cement mixers to different sides of the property to reduce impacts on individual neighbors. What can you do about construction noise? • The use of radios on the site before 8:00 am are not allowed: remind laborers and sub- contractors. • Noise suppression plans will not allow noisy machines such as brick cutters or jackhammers to be operated before 9.00 am. • Noisy equipment such as cement mixers should be placed on the site to maximize the distance from neighboring houses and/or rotate location so as to not impact just one neighbor. Noise levels drop quickly with distance from the source. • All equipment should be properly maintained, with special attention to mufflers and other noise control devices. • Between work periods, builders are required by city ordinance to shut down machines such as backhoes, bobcats, loaders and generators. • When dropping materials from a height—for example, into or out of a truck, or when loading or unloading scaffolding, noise suppression plans require a chute or side baffles. • All vehicular movements to and from the site must only be made during the scheduled normal working hours. This includes off-site noise that is associated with a specific project such as staging of concrete trucks.

Specific Equipment: Generators: The local power grid shall be used wherever feasible to limit generator noise.No generators larger than 25 KVA shall be used and,where a generator is necessary, it shall have maximum noise muffling capability. Backup Alarms: All equipment with backup alarms operated by the Contractor,vendors, suppliers, and subcontractors on the construction site shall be equipped with either audible self-adjusting ambient-sensitive backup alarms or manually- adjustable alarms. The ambient-sensitive alarms shall automatically adjust to a maximum of 5 dBA over the surrounding background noise levels. The manually-adjustable alarms shall be set at the lowest setting required to be audible above the surrounding noise. Installation and use of the alarms shall be consistent with the performance requirements of the current revisions of Society of Automotive Engineering (SAE)J994, J1446, and OSHA regulations. Compressors: The unit with the lowest noise rating which meets the requirements of the job should be used where work is conducted in the City of Aspen, installed with mufflers and/or enclosed in a noise barrier. RECEIVED Revised 9/27/07 0 3/2 7/2 019 ASPEN BUILDING DEPARTMENT Jackhammer: All jackhammers and pavement breakers used on the construction site shall have exhaust systems and mufflers that have been recommended by the manufacturer as having the lowest associated noise and shall be enclosed with shields or acoustical barrier enclosures. Concrete crushers or pavement saws: Pre-augur pile holes to reduce the duration of impact or vibratory pile driving and tie to local power grid to reduce the use of generators and shall be enclosed with shields or acoustical barrier enclosures. Pneumatic hand power tools: All pneumatic tools operated in the City of Aspen must be fitted with an effective silencer on their air exhaust port. Temporary Noise Barrier Materials: Temporary barriers shall be constructed of 3/4-inch Medium Density Overlay(MDO)plywood sheeting, or other material of equivalent utility and appearance having a surface weight of 2 pounds per square foot or greater. The temporary barriers shall be lined on one side with glass fiber, mineral wool, or other similar noise curtain type noise-absorbing material at least 2-inches. The materials used for temporary barriers shall be sufficient to last through the duration of the construction project, and shall be maintained in good repair. Prefabricated acoustic barriers are available from various vendors. An equivalent barrier design can be submitted in lieu of the plywood barrier described above. Impact Equipment: Impact noise is noise produced from impact or devices with discernible separation in sound pressure maxima. Examples for impact equipment include, but are not limited to;blasting, chisel drops,mounted impact hammers (hoe ram), and impact pile drivers. Impact equipment is the loudest and most intrusive to the neighboring property. The City of Aspen requires that this type activity have the strictest mitigation requirements and requires a customized noise suppression plan specific to the site.
