ADEQUATE PROVISIONS FOR WATER NEEDS: Sections 2-17 and 3-1104: "It is the policy of the County to insure the availability of a water supply of adequate quality, quantity, pressure and dependability for fire protection and support of a proposed land use prior to approval of the use. The County shall require land uses to hook up to existing public systems if service is available." Since the source of potable water for the proposed residences and attached caretaker units will be domestic wells, this Department will need adequate information on the quantity and quality of water available. This can be done from tests of wells present on-site by a water engineer's or well driller's report. The applicant must ensure that the water quality is acceptable by having it tested by a lab such as Snowmass Water and Sanitation. Before a septic permit can be issued the location of the well should be confirmed to assure that setback requirements from the well to the septic system can be complied with. It is our recommendation that the well(s) are drilled first before installation of the sewage disposal system or construction of the dwelling. It is recommended that low water landscaping (xeriscaping) be used and that the timing of any sprinkler systems be decreased for low water plants. The Colorado State University Cooperative Extension office can be contacted for more information on xeriscaping. A condition of approval for this application is the receipt of information documenting the location of the wells and quantity/quality of the well water. SEWAGE TREATMENT AND COLLECTION: Sections 2-18 and 3-1105: °It is the policy of the County to insure that adequate sewage treatment facilities are available to serve existing and new developments. Public and private sewage disposal systems and connections to such systems shall comply with the sewage disposal guidelines of Pitkin County Code Title X." Lots in the Brush Creek area are served by individual sewage disposal systems. All such systems installed within Pitkin County require septic permits issued by the Environmental Health Department, and must comply with the County septic regulations before a building permit can be issued. To receive a septic permit, the applicant will need to submit a septic permit application and appropriate fee with a completed soil data form including perc test results and profile hole information. We do not recommend the final design be submitted to the Environmental Health Department for approval before a health officer has had a chance to review the data and make his/her own design recommendations. The Aspen/Pitkin Environmental Health Department will design the system for the applicant as part of the permit fee, unless an engineered system is needed, which we determine based on soil test results. An engineered system is required if any one of the following conditions occurs: a percolation rate faster than 5 mpi or slower than 60 mpi; maximum seasonal level of the groundwater table or bedrock less than four feet below the bottom of the proposed absorption system; or a slope in excess of 30%. The presence of Mancos shale may require that an engineer design the system if bedrock or groundwater are encountered. The applicant should be aware that Pitkin County's sewage disposal regulations are in the process of being revised and will probably become effective sometime this spring. A septic system for a home in excess of 6,000 square feet may be sized using the figure of 130 gallons per person per day. As a result, the septic system's size requirements will increase. The applicant will need to adhere to minimum horizontal setback requirements for placement of septic system components away from pertinent physical features. The setbacks from the existing septic system and well at the red farm house must be maintained. The following setbacks are significant at this site: *100 feet between wells and absorption fields 25 feet between an absorption field & a lined irrigation ditch * 50 feet between an absorption field & unlined ditch * 50 feet between an absorption field & Brush Creek * 8 feet of additional distance will be added for each 100 gallons per day of average daily waste flow over 1,000 t- t gallons per day. The Wiese irrigation ditch should be lined to eliminate the possibility of soil saturation in the absorption field area which would compromise the septic system's effectiveness. The applicant should refer to the Pitkin County Sewage Regulations and contact this Department for detailed information and a site specific evaluation. A condition of approval for and approval of the septic Health Department before a this application is the receipt permit by the Environmental building permit can be issued. WATER QUALITY IMPACTS: Sections 2-14 and 3-705 and 3-710: "It is the policy of the County to preserve and protect its present water resources. To this end it is the policy of the County that no land use be initiated which would adversely affect the quantity, quality, or accessibility of the County's water resources; or which would occur at the expense of established water - dependent agricultural activities; or which would result in increased salinization of water resources, loss of minimum stream flows, further destruction of wildlife habitat, or major expenditures to reacquire or redistribute major water resources. It is also the policy of the County to maintain a natural vegetative buffer along its Surface waters such that the surface and groundwaters of the area are not encroached upon by land uses or other human activities which could cause deterioration of water quality or impair the natural treatment processes provided by meadows and wetlands." The Environmental Health Department will be addressing water quality impacts on down stream water quality and specifically Brush Creek which runs through the property. There are no conditions of approval at this time, however, the Department reserves the right to require groundwater and creek monitoring at the homeowner's expense. AIR QUALITY: Sections 2-13 and 3-602: "Only that development is permitted which will not contribute significantly to degradation of air quality in Pitkin County. Developments may not constitute an indirect or direct air pollution source under Federal, State or County regulations." This project is an indirect source of air pollution and is expected to contribute to degradation of air quality in Pitkin County by adding traffic in the non -attainment area. However, the project can be approved as long as the applicant mitigates the increases in traffic and PM10. The Environmental Health Department can assist the applicant in devising a sufficient mitigation program. Due to the relatively small size of this project, it will be easy to mitigate the impacts by measures such as paving or construction of a bike path section. Activities such as road building and landscaping may require a Fugitive Dust Plan. This plan would need to include, but is not limited to, fencing, watering of haul roads and disturbed areas, 3 f 10 daily cleaning of adjacent paved roads to remove mud that has been carried out, speed limits, or other measures necessary to prevent windblown dust from crossing the property line or causing a nuisance. A condition of approval will be that prior to detailed submission, the applicant must submit an air quality mitigation plan which the Environmental Health Department will determine whether or not the plan mitigates the projects air quality impacts. The less densely populated parts of the county like Brush Creek Village may have one wood burning fireplace and one department certified device or two department certified devices per building (not per residence). In addition, unlimited numbers of decorative gas appliances are allowed. Coal may not be burned in any device. No wood burning device may be installed in barns or agricultural buildings. A condition of approval for this application will be the receipt and approval of the fireplace/woodstove permit by the Environmental Health Department before the building permit can be issued. CONFORMANCE WITH OTHER ENVIRONMENTAL HEALTH LAWS: Section 2-7: "It is the policy of the County to ensure that no use or development of Land is permitted which is in violation of the Daws of the County, the State of Colorado, or the United States of America." This Department is not aware of any issues of concern regarding other environmental health laws. ...
