The City of Aspen Engineering Department is the administrative authority for stormwater management and erosion prevention and sediment control on construction sites within the City's jurisdiction. By policy, Aspen's requirements for stormwater management during construction are consistent with those of the Colorado Department of Public Health and Environment's (CDPHE) Construction General Permit. The CDPHE Construction General Permit requires a stormwater management plan (SWMP) for development disturbing greater than one acre of land. However, Aspen requires a Construction SWMP detailing pollution prevention and erosion prevention and sediment control measures to be installed for projects that exceed 1000 square feet of soil disturbance, not just those that disturb greater than one acre. Wherever the City of Aspen and the CDHPE Construction General Permit requirements are in conflict, the more restrictive requirements should be applied. The regulations and guidelines stated in this chapter incorporate information from a variety of sources including: • The United States Environmental Protection Agency(EPA), • State of Colorado/Colorado Department of Public Health and the Environment(CDPHE), • Urban Drainage and Flood Control District (UDFCD),and • Northwest Colorado Council of Governments(NWCCOG). It is important to understand that these regulations are subject to change and/or alterations. For the most up to date copy please contact the City of Aspen Engineering Department. 1 .1 PURPOSE Some construction activities and materials have the potential to pollute our streams, rivers, and lakes if transported during storms or snowmelt. When construction disturbs land, the soil is more easily eroded during rainfall, snowmelt, and wind events. Eroded soil, referred to as sediment, is the greatest pollutant to rivers in Colorado and Aspen. Sediment endangers water resources by reducing water quality and causing the siltation of aquatic habitat for fish and other desirable species. Other pollutants, such as petroleum products, metals, and nutrients, easily attach to soil making sediment even more toxic. Eroded soil also necessitates the cleaning and/or repair of sewers and ditches and the dredging of water bodies. Therefore clearing, grading, and vehicle tracking during construction creates the need for erosion prevention and sediment control on construction sites. Pollutants other than sediment, such as concrete, solvents, oil, grease and metals, also cause degradation of water quality in receiving streams, and therefore must also be prevented or reduced through construction site stormwater management practices.The City of Aspen requires compliance with the criteria in this chapter in order toRECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT eliminate or reduce the discharge of pollutants in stormwater runoff and prohibits the discharge of pollutants from construction sites to the City's stormwater system. These criteria should be followed from start of earth disturbance until final landscaping and stormwater quality measures are effectively in place and accepted by the City. The goal of these requirements is to decrease the amount of pollutants entering the stormwater system from construction and other land disturbing activities. The following erosion prevention, sediment control, and pollution prevention measures are designed to safeguard persons, protect property, minimize water quality and other environmental impacts, and promote the public welfare by guiding, regulating, and assisting the design, construction, use, and maintenance of any development or activity which disturbs or breaks the topsoil or results in the movement of earth on land greater than 1000 square feet in the City of Aspen, Colorado. 1 .11 General Requirements A Construction Stormwater Management Plan (Construction SWMP) must be developed before a project begins that identifies pollution prevention measures and erosion prevention and sediment control (EPSC) measures that are appropriate for the actual site conditions and construction plans for each site — generic plans will not be approved. The Construction SWMP shall contain a narrative report as well as site plan maps for each phase of the project. The appropriate schedule of implementation shall be identified as well as detailed plans shown on plan sheets with appropriate contours for each phase of the project that will minimize pollution, erosion, and sediment transport. The Construction SWMP shall be submitted to the City of Aspen as part of the Construction Mitigation Plan (CMP) and along with the grading and drainage plans in order to obtain a building or landscape and grading permit. Plans for grading and erosion control should be considered in the early stages of site planning and drainage design. The Construction SWMP may have to be modified at the time a final site development plan is prepared to better address the site conditions as the plan changes. This modified plan, the final Construction SWMP, must be approved by the City of Aspen before ground-breaking activities can occur. EPSC measures must be designed according to size, slope, and soil type of disturbed drainage areas to prevent erosion and to capture sediment. Potential sources of pollution that might affect quality of stormwater discharges from the site, and practices that will be implemented to prevent that pollution, must be identified and described as part of the Construction SWMP. In addition, sites discharging directly to waters of the state or the City's stormwater system might be required to meet stricter requirements as determined by the City Engineer or City Stormwater Manager. Implementation of the Construction SWMP (i.e., installation of measures) begins when construction begins, before the initial clearing, grubbing, and grading operations, since these activities can usually increase erosion potential on the site. Implementation and maintenance of pollution prevention measures and EPSC measures are the responsibility of the permit holder and the project/property owner. Because site conditions will affect the suitability and effectiveness of pollution prevention and EPSC measures, the SWMP is a dynamic document that should be referred to frequently, amended and updated as necessary, and kept on site available for review by City of Aspen staff upon request. The City reserves the right to require the permit holder and/or property owner to develop and implement additional measures to prevent and control pollution as needed. RECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT Pollution Prevention Pollution prevention for construction within the City of Aspen requires compliance with the following criteria: 1. Develop Construction SWMP - The Construction SWMP must identify potential sources of pollution that may reasonably be expected to affect the quality of stormwater discharging from the site. 2. Practice Good Housekeeping - The Construction SWMP must describe standard operating procedures and practices that will be implemented to prevent the release of pollutants to the stormwater system from construction activities. a. Perform activities in a manner to keep potential pollutants from coming rb contact with stormwater. b. Prevent spills and leaks (i.e. hydraulic fluid from leaky vehicles or equipment) c. Use phasing principals to limit areas of disturbance. 3. Contain Materials and Waste —Areas used for staging of construction activities and the storage of soil, chemicals, petroleum-based products and waste materials, including solid and liquid waste, shall be designed to prevent discharge of pollutants in the runoff from the construction site. a. Store construction, building, and waste materials in designated areas, protected from rainfall and contact with stormwater run-on and runoff. b. Dispose of all construction waste in designated areas (e.g. concrete may only be disposed of in a designated concrete wash-out area) and keep stormwater from flowing onto or off of these areas. c. Properly clean and dispose of spilled materials. 4. Dewatering — If it is determined that site dewatering will be required, the permit holder/ and or property owner must obtain a Construction Dewatering Permit for the CDPHE division of water resources. Erosion Prevention and Sediment Control Erosion prevention and sediment control for construction within the City of Aspen requires compliance with the following criteria: 1. Develop Construction SWMP —The Construction SWMP plan must demonstrate how stormwater, erosion, and sediment will be handled throughoutconstruction. 2. Control Site Perimeter— Construction activities and their impacts must be controlled within the limits of the site. a. Delineate the site perimeter on the plans and in the field to prevent disturbing areas outside of the project limits. b. Divert upstream run-on safely around or through the construction project. Diversions must not cause downstream property damage and cannot be diverted into another watershed. c. Construction vehicles and equipment may enter and exit the site at only one designated access point. This exit must be stabilized with gravel or other appropriate material throughout the duration of the project. 3. Minimize Disturbed Areas — Construction activities must be scheduled in correct sequences to minimize the total amount of exposed soil at any given time. a. Only clear land which will be actively under construction in the near term (e.g. within the next 1-2 months). b. Minimize new land disturbance during the spring runoff/snow meltseason. RECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT c. Avoid clearing or disturbing sensitive areas, such as steep slopes and natural waterways, where site improvements will not be constructed or are not necessary. 4. Stabilize Disturbed Areas — Disturbed areas must be permanently or temporarily stabilized as soon as possible, but no later than 14 days after last worked, whenever active construction is not occurring on that portion of the site. Disturbed areas must be stabilized by November 15th of each year to minimize erosion and sediment transport that occurs during spring snow melt. 5. Protect Slopes and Channels — Concentrated stormwater flows shall be avoided, or the conveyance system shall be protected sufficiently to prevent significanterosion. a. Safely convey runoff from the top of the slope and stabilize disturbed slopes as quickly as possible. b. Avoid disturbing natural channels. c. Ensure the runoff velocity caused by project does not erode channel bottoms. 6. Install and Maintain EPSC Measures — All sites must minimize pollution potential by installing and maintaining erosion prevention and sediment control measures throughout the duration of any project. a. Erosion prevention measures are those BMPs used to limit erosion of soil from disturbed areas on the site. Erosion prevention measures are required for all disturbed areas. Examples include: Contour Tracking, Rolled Erosion Control Products, Hydro Mulching and similar activities. b. Sediment control measures are those BMPs the limit the transport of sediment off-site or downstream of disturbed areas. Sediment control measures are required for all disturbed areas. The most commonly used sediment containment is silt fencing. c. Use non-structural and structural best management practices (BMPs)described in this chapter. d. All sites must be inspected regularly by a representative from the project to document the condition and effectiveness of BMPs. 7. Retain Sediment - Sediment control measures are required at all points where stormwater leaves the site as concentrated flow and at any other points where sediment has the potential to leave the site. Sediment-laden runoff will be considered a violation of City of Aspen code and can receive fines up to $1000 per day that the site is in violation. Best Management Practices Best Management Practices (BMPs) are activities or controls that are implemented to reduce the potential of discharging pollutants to the stormwater system and include pollution prevention measures and EPSC measures. 2.1 Permit and Construction Process Step 1 — Develop Construction SWMP The owner or the contractor should secure the services of a professional engineer knowledgeable in construction management practices and the City of Aspen requirements for stormwater management during construction to develop the Construction SWMP. The SWMP must be submitted as a portion of the CMP along with the building permit application. The Construction SWMP will be reviewed by the City and its comments will need to be addressed before a building permit will be issued. RECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT Projects that disturb greater than one acre of land will also need to apply for a Construction General Permit with the CDPHE. This application also requires the submittal of a SWMP. The Construction SWMP developed for the purposes of construction within the City of Aspen should be adequate to submit with the Construction General Permit Application. The Construction SWMP shall consist of a written narrative report and a site plan map describing the erosion prevention and sediment control measures to be implemented at the site. Narrative Report The narrative report must contain, or refer to, the drainage report for the site and should contain, at the minimum, the following: 1. Contact Information —The names, addresses, email addresses and phone numbers of the project/property owner, the applicant or permit holder, the professional engineer preparing the Construction SWMP, and the site person that will be responsible for implementation of the Construction SWMP. 2. Project Description - A brief description of the nature and purpose of the land disturbing activity, the total area of the site, the area of disturbance involved, and project location including township, range, section, and quarter-section, or the latitude and longitude, of the approximate center of the project. 3.

Should the field representative change, this block should be updated with a signature of the current site representative that will be responsible for implementation of the SWMP. RECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT Step 2 — Approval of Construction SWMP The Construction SWMP must be approved prior to issuance of a Building Permit by the City. The final SWMP must be consistent with a Drainage Report accepted by the City of Aspen Engineering Department. However, approval of the SWMP does not imply acceptance or approval of Drainage Plans, Utility Plans, Street or Road Plans, Design of Retaining Walls or any other aspect of site development. 2.2.1 Exemptions and Variances These are generally processed according to the applicable municipal regulations and reviewed on a case-by-case basis. 1. Exemptions from the erosion control planning process may be considered for any of the following by the local jurisdiction if their MS4 permit so allows; however, exempting the owner from the preparation and submittal of a SWMP and/or from applying for a grading permit does not exempt the owner from controlling erosion and sediment movement off the construction site: a. Agricultural use of land. b. Grading or an excavation below finished grade for basements, footings, retaining walls, or other structures on single family lots not a part of a larger development or redevelopment project and disturbing a total land surface of less than one (1) acre in size unless required otherwise by local jurisdiction. c. A sidewalk or driveway authorized by a valid permit. d. Land-disturbing activities involving less than a total of one (1) acre of disturbed area. Individual lots involving less than one (1) acre of disturbed area in a larger land use change project shall not be considered separate development projects, but rather as a part of the subdivision development as a whole and are not eligible for an exemption. It will be the responsibility of the homeowner or homebuilder to conform to all requirements of the locally- approved SWMP for the development or redevelopment. As part of any Building Permit within a larger development for which an individual erosion control plan is not required, it is recommended the following statement be included: "We have reviewed the Construction Storm Water Management Plan for (subdivision name) and agree to conform to all requirements contained therein and all erosion control requirements of the (insert name of municipality) and the State of Colorado. We further agree to construct and maintain all erosion and sediment control measures required on the individual lot(s) subject to this Building Permit and/or in accordance with the provisions of the Construction Best Management Practices chapter of the Manual published by the Urban Drainage and Flood Control District." e. Underground utility construction including the installation, maintenance and repair of all utilities under hard-surfaced roads, streets or sidewalks provided such land-disturbing activity is confined to the area which is hard-surfaced and if runoff and erosion from soil stockpiles are confined and will not enter the drainage system. f. Gravel, sand, dirt or topsoil removal as authorized pursuant to approval of the Colorado Mined Land Reclamation Board, provided said approval includes a construction activities management, erosion and sediment control plan that meets the minimumsspecified. g. Projects having a period of exposure (from time of land disturbance until permanent erosion control measures are installed) of less than 14days. h. Where the owner certifies in writing to the City of Aspen and the City of Aspen agrees in writing that the planned work and the final structures or topographical changes will not result in, or contribute to, soil erosion or sediment discharges to any waterway or irrigation ditch and will not interfere with any existing drainage course or waterway in such a manner as to cause damage to any adjacent property, or result in the deposition of debris or sediment on any public right-of-way, will not present any hazard to any persons or property, and will have no detrimental influence upon the public welfare, or upon other properties in thewatershed.RECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT 2. Variances — The City of Aspen may consider waiving or modifying any of the criteria which are deemed inappropriate or too restrictive for site conditions by granting a variance, provided such variance does not violate the laws of the State of Colorado or the Federal government. Variances may be granted at the time of plan submission or request for plan revision.Variances must be requested in accordance with the subdivision regulations and mustdefine: a. The criteria from which the applicant seeks a variance. b. The justification for not complying with the criteria. c. Alternate criteria or standard measures to be used in lieu of these criteria. The criteria and practices specified within this section of the Manual relate to the application of specific erosion and sediment control practices. Other practices or modifications to specified practices may be used if approved by the municipality prior to installation. Such practices must be thoroughly described and detailed to the satisfaction of the local municipality reviewing and approving the erosion control plan. To expedite the review and decisions on variance requests, it is suggested that a variance request be included with, or submitted prior to, the initial SWMP submittal. Step 3 — Project Construction — Installation, Maintenance, and Inspections During the construction phase, the following sequence is recommended for the implementation of the project and the SWMP: 1. During preparation of the Construction SWMP, the contractor designated a manager for the implementation of the SWMP. This person will be responsible for implementing all permit conditions and will communicate with City inspectors and inspectors from other agencies. 2. Install all BMPs shown on the SWMP that need to be installed in advance of proceeding with construction, such as construction fencing and limits of disturbance, tree and other natural area protections, construction exits, silt fences, inlet protection,etc. 3. Identify construction equipment and materials storage and maintenance areas and install BMPs to prevent pollutant migration from them. 4. Notify the City that the site is ready for initial inspection. 5. Install any additional BMPs that are called for in the SWMP before grading begins. a. Strip off and stockpile topsoil for reuse. Insure that soil stockpile is not located in a drainage path, downhill of a significant drainage area, is protected from erosion and dust migration, and that a sediment control measure is located downstream. b. Mulch areas that will remain undisturbed for more than two weeks during the April through September rainstorm season (e.g., stockpiles and overlot graded areas that will remain dormant for an extended period of time), or for more than a month during the October through March period. c. Insure that BMPs that need to be installed at different times during the project are installed when called for in the SWMP or by the City's inspector and are in full operation before construction activities begin in areas served bythem. RECEIVED 11/12/2021 ASPEN BUILDING DEPARTMENT d. Inspections by site Supervisor/ Professional Engineer e. Inspections by City will occur regularly to inspect for general compliance with the approved plan. f. Maintenance by the permit holder/and or property owner is required for all BMP's regardless of the stage of construction. g. Maintenance time frame from City h. Enforcement from City will occur at any time when a permit holder / and or property owner is in violation of the SWWP. Enforcement will escalate from verbal notices of corrective actions to stop work orders based on the number of violations or the severity of any one single violation. Step 4 — Project Completion — Stabilization, Re-vegetation, and CO Re-vegetate the site as called for in the SWMP. 1. After all work has been completed in an area a. including stabilization and re-vegetation, b. clean out and restore any post construction BMPs that may have been used for construction sediment controls. After all work has been completed on site, prepare the site for a CO inspection by the City and arrange for this inspection by calling (970) 920-5448. Correct all deficiencies and call for follow- up inspection. The owner or contractor needs to arrange for inspection by the local jurisdiction when the vegetation has reached acceptable level of coverage and maturity. This could take months. In the meantime, the owner or contractor need to inspect the site on a regular basis to determine if there are deficiencies or damage that need to be addressed. The owner is responsible for the performance of all erosion and sedimentation control installations until such time the site's re- vegetation is deemed acceptable and a written notice is provided to the owner by the local jurisdiction. Once re-vegetation has been accepted, request release of any surety, letters of credit or other financial guarantees the local jurisdiction may have required the permit holder provide at the time the permit is issued. A closure of the construction activities permit from the State should also be pursued at this time.
