The Pitkin County Board of Commissioners has declared in the Pitkin County Individual Sewage Disposal System Regulation (Regulation), support for alternative methods of wastewater disposal not otherwise provided for in the Regulation. In this case such an alternative system commonly known as Drip Irrigation shall be declared "experimental." 2. The Pitkin County Board of Commissioners has declared in the Regulation that the experimental system must be designed by a Registered Professional Engineer prior to submittal to the Aspen/Pitkin Environmental Health Department for review. 3. The Pitkin County Board of Commissioners, acting as the Pitkin County Board of Health(PCBOH) recognizes, and the Regulation states: "The Local Board of Health may not arbitrarily deny any person the right to consideration of an application for such a system and shall apply reasonable performance standards in determining whether to approve an application." NOW, THEREFORE BE IT RESOLVED by the Board of County Commissioners of Pitkin County, Colorado,that the use of"Drip Irrigation" as an experimental wastewater disposal system in Pitkin County meets the conditions of the Regulation to be declared experimental, and sitting as the Pitkin County Board of Health declare approval for installation of a total of twenty-eight(28) such systems in the County with the following conditions: 1. Any permit for installation of a Drip Irrigation wastewater disposal system must be issued in the name(s) of the legal owners of the property involved, must contain an accurate description of the property, and must conspicuously display the requirements in Section 4-20 of the Regulation, titled; "Experimental Systems." 2. The Pitkin County Board of Health and the Aspen/Pitkin Environmental Health Department will assume no liability in the act of issuing a permit for a Drip Irrigation wastewater disposal system, either for design or performance. 3. The permit issued for a Drip Irrigation wastewater disposal system shall be recorded in real estate records for the property served by the system. This recording is for the purpose of putting future purchasers on notice that an experimental sewage disposal system serves their property. 4. The applicant must commit to follow the recommendations of the Aspen/Pitkin Environmental Health Department (Department), and those of the Registered Professional Engineer consultant to the Department if approval is given to install the experimental system. 5. As is stated in the Pitkin County ISDS Regulation, Section 4-20; The applicant must provide for a "... timely installation of a backup system of a type described in this regulation if the experimental system fails." The lot on which a Drip Irrigation system is to be installed must be large enough to accommodate a traditional Individual Sewage Disposal System (ISDS) so that if the Drip Irrigation system fails and cannot be repaired, the owner will have room to construct a replacement system. This is consistent with previous PCBOH actions on experimental systems as found in Section 12-8.1 of the ISDS Regulation. 6. If a "water balance" method of calculating waste load is applied, the applicant must provide a monitoring plan to determine the saturation status of soils, especially in the early spring months when the leaching bed is at its peak storage. 7. The applicant must provide a written report to the Environmental Health Department documenting maintenance on the system (such as when the filters are changed and when the valve regulating field use is activated). The soil saturation data requested in condition 6 above must also be reported. The reporting must continue for a period of five (5) years, and be submitted to the Environmental Health Department in January of each year. 8. The installation of a filter after the final septic tank to remove any material which may remain to clog the distribution line ports will be required. 9. Since Drip Irrigation is promoted as an ISDS that is suitable for poor percolating soils, it assumes the form of a modified evapotranspiration (ET) system. In some cases it may be an evaotranspiration/absorption system using both air and plant evaporation with minimal soil absorption. Section 12-6.4 of the Pitkin County ISDS Regulation requires placement of these type systems, "...in an area where there is exposure to sunshine enough days per year and hours per day to allow for adequate functioning of the system, and must take into account the number of months per year in which the area is covered with snow. ET systems may not be used in shaded north-facing areas in valleys, for example, but must be in areas that are open to sunshine and exposed to sufficient breezes." 10. Pitkin County ISDS Regulation requires a water flow "peaking factor" in the design of ISDS. However, since no "daily peaking factor" is figured in the calculation of the Drip Irrigation wastewater disposal system, and this is a significant variation from the Regulation, this requirement is waived with the condition that only a total of twenty eight (28) systems using this modification be allowed in Pitkin County until it can be verified that the public health of residents, and the environmental health of surface and ground water is not compromised. 11. The owner will be required to submit a final "as-built" drawing to the Environmental Health Department upon completion of the installation. This drawing must be submitted by the engineer (or his/her designated representative) who provided the approved design that was the basis for permit issuance.
