MERRY, REHS Director RE: Final approval of Individual Sewage Disposal System ISDS Permit #:2490-05; Tax parcel #:247106307001; Property location: 000158 McLaughlin Lane, Basalt Dear Doren, This letter is to inform you that the above -referenced ISDS Permit has been inspected and finalized. Your septic system has been sized to accommodate 4 bedrooms. Enclosed is a copy to retain for your records along with a brochure regarding the care of your septic system. Additional information about the maintenance of your septic system as well as information about private wells can be accessed through web site links provided on the Environmental Health Department's home page at http://www.eaglecounty.us/envHealth/ Be aware that changes in the use of your property or alterations of your building may require commensurate changes to, or relocation of, your septic system. Landscape features, trees with tap roots, irrigation systems and parking areas above the drain field can cause premature system failure. It is equally important that you notice and immediately repair dripping faucets and hissing toilets as this will certainly cause the system to fail. By following a few simple guidelines, like avoiding grease or other additives down the drain and making sure your septic tank is on a pumping schedule, your system has been designed to last for many years. If you have any questions regarding this system please contact us at 970-328-8755 Sincerely, Terri Vroman Administrative Technician IV cc: ISDS permit folder Eagle County Building Department Chrono efile Encl: Final ISDS Permit Informative materials 500 Broadway, P.O.

Box 1078 Silt, Colorado 81652 Subject: OWS Design - Mushet Residence 158 McLaughlin Lane Lot 28, Reudi Shores Eagle County, Colorado Job No. C256 Mr. Jaffrey, RECEIVED JUN 12 2006 ENVIRONMENTAL As requested, CHURCH Onsite Wastewater Consultants, LLC (COWC) designed an onsite waste- water system (OWS) for a proposed residence. Subsurface conditions were investigated by H-P Geotechnical, Inc. in their Job No. 105 777 dated November 30, 2005. SITE CONDITIONS The site is a 1.12-acre lot located in a rural -residential area in Eagle County, Colorado. The location of the proposed residence is presented on Figure 1. The area of the proposed OWS site slopes moderately, 20-25%, down to the southeast. PROPOSED CONSTRUCTION A 4-bedroom residence is proposed. The residence will be supplied water by the homeowners association. The proposed location of the residence is presented on Figures 1 and 2. In accordance with the Individual Sewage Disposal System (ISDS) regulations, the sewage load for a four -bedroom residence is 600 gallons per day (GPD). The peak sewage loading is 900 GPD using a 1.5 peaking factor. SUBSURFACE CONDITIONS Subsurface conditions were investigated as presented in the November 30, 2005 H-P Geotech- nical Inc. report. Subsurface conditions were investigated by digging an exploratory pit in the vicinity of the proposed drain field area. The subsurface conditions consisted of 3 to 3.5 feet of topsoil underlain by relatively stiff, sandy clay with occasional gravel to a depth of 11 feet, the maximum depth of the pit. No free water was observed in the profile pit on November 1 or 2, 2005. Percolation test results indicate percolation rates ranging from 24 to 240 minutes per inch (MPI), with an average of 128 MPI. A percolation rate of 120 MPI was selected for this OWS design. P.O. BOX 527, Wheat Ridge, CO 80034-0527 Voice: 720-898-3434 FAX: 720-898-3455 OWS Design, Job No. C256 06-02-2006, Page 2 RECOMMENDATIONS The results of our design indicate an OWS can be installed at the location presented on Figure 2. The proposed OWS consists of a septic tank with dosing pump and drip irrigation drain field. The location of the sewer stub -out from the building is unknown. The septic tank should; 1) be located down gradient of the home, 2) be buried no deeper than three feet, and 3) at a location accessible for pumping and maintenance at the tank. If COWC can assist with locating the septic tank after the stub -out location is identified, please call. A 1500-gallon two -compartment precast concrete septic tank with an Orenco Systems, Inc. (OSI) Biotube® pump vault installed in the second compartment is proposed. An OSI Model P50 or P30 high head pump is recommended. The pumping system is discussed below. The drain field is designed for a four -bedroom residence based on an average sewage load of 600 GPD and an application rate of 0.21 gallons per day per square foot (Gal/Day/ftZ), The fields will consist of a 6200 ft2 low-pressure drip irrigation drain field installed in five 10-foot by 100-foot sections and one 12-foot by 100-foot section. The OWS should be constructed similar to details in Figures 2 through 6. Vehicular movement over the drain field area during construction should be kept at a minimum to avoid compaction of the receiving soils. Dump trucks and rubber -tire backhoes are to be kept out of the proposed field area. The surface of the field should be seeded after installation of the system. A seed mix such as a "Foothills, Pasture, or Prairie" mix should be sown. These mixes do not require irrigation and may develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the field. If intended use of the site includes support of livestock, the field area should be fenced. EFFLUENT PUMPING SYSTEM The proposed pumping system must meet the following minimum specifications: Pumps - The pumps selected for the pump vault should have a minimum capacity of 30 gallons per minute, a minimum Total Dynamic Head of 15 feet. A minimum power rating of 1/2-Horsepower (230-volt) is recommended for the pump. The pumps shall be UL and CSA listed as an effluent pump. Manufacturer pump curve diagrams are attached. Access Risers— Access risers that extend to final grade must be provided. The risers are to be watertight and attached to the septic tanks such that a watertight seal is provided. Risers should be rated for the appropriate load requirements. Discharge Assembly — The pump discharge assembly is to have a disconnect union accessible from the ground surface to allow pump replacement. The discharge assembly is to be plumbed with a weep hole to allow for drainage between cycles to minimize freezing potential. Float Switch Assembly — The on/off and high water alarm floats are to be accessible for adjustment without removing the pumps or vault. Pump float switches should be set to discharge approximately 150 gallons per dose to the drain field. OWS Design, Job No. C256 06-02-2006, Page 3 Electrical Splice Box— The splice box shall be UL approved for wet locations. All wire splices are to be completed with UL listed waterproof splice connectors. Controls and Alarms — Controls and alarms shall be listed per UL 508. Controls are to include a toggle switch for manual operation of the pumps; separate dedicated circuits for the pumps and the high water alarm; an audible and visual alarm; and an elapsed time meter. Panels are to be NEMA 4X rated. Location —The pump control panels are to be mounted within sight of the respective pump system. The panels are also to be located such that the alarm can be readily seen and heard (remote alarms to a location within the buildings can be provided). The panels are to be mounted at convenient heights to allow access and maintenance. INSTALLATION OBSERVATIONS Observation is required prior to backfill. At that time, the septic tank is to be installed with risers on the tank, and inlet and outlet connections properly bedded. The drain field is to be ready for backfill with dispersal pipes in place. Other components such as distribution valves, effluent filters or pump basin will be observed at that time. Our office should be called at 720-898-3434 to observe the installation of the OWS at least 24 hours in advance. One installation observation is required for this design. Installation observations, repeat observations, OWS redesigns, re -staking of drain fields or additional site visit requirements are not included with this design and will be at an additional fee per our service agreement and/or fee schedule. OPERATION AND MAINTENANCE The owner must realize an OWS is different from public sewer service. The owner must assume responsibility for maintenance of the system. The system is relatively maintenance free, but the owner must have the septic tanks pumped. COWC recommends the septic tanks be pumped every two years and the filter be cleaned after pumping or as needed. The distribution valves control flow of effluent to each section of the field. One section of the field should be closed at a time to allow periodic drying of each segment of the field to extend the life of the field. This can be accomplished by sequentially rotating the valves one or more times year a year. There are also daily considerations, such as not putting plastic or other non -biodegradable material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a malfunctioning toilet can consume in excess of 1000 GPD. An excess 1000 GPD loading could flood and irreparably harm the OWS. COWC cautions against installation of a water softener. The chemical and hydraulic loading from the backwash of a water softener may be detrimental to the OWS and a separate drywell should be constructed for the backwash waste, if a softener is installed. No landscaping or plastic can be used over the field, which will reduce performance of the field. Chemically treated water from a swimming pool or spas should not be introduced into the OWS. The design of the OWS is based on the treatment of domestic sewage only. No industrial or hazardous wastes should be introduced into the OWS. OWS Design, Job No. C256 06-02-2006, Page 4 LIMITATIONlS An OWS design requires installation by a contractor who is experienced in its installation. Our investigation, layout, design, and recommendations are based on data submitted. If conditions considerably different from those described in this report are encountered, we should be called to observe the conditions. If proposed construction is changed, we should be notified to evaluate the effect of the changes on the OWS. All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifications that are not depicted in our report are to conform to the requirements of the ISDS regulations. The installer of the system is to be approved by the county health department, and is to have demonstrated knowledge of the ISDS regulations and requirements. If there are questions, please call.

A 1500-gallon two -compartment precast concrete septic tank with an Orenco Systems, Inc. (OSI) Model 312 dosing siphon installed in the second compartment is proposed. The field installation includes three 64 foot trenches containing 16 Infiltrator Quick 4 chambers each for a total of 48 chambers. The chambers sho++i nA installed a maximum of 1—fnnf hPlow ;;Le surface and soil hn+ WwWLwnl nn t �n of t ha_sbamlers for Oyer, The maximum 1-foot excavation is because of the poor percolation rates in the lower layer of clay soil. The OWS should be constructed similar to the details in Figures 2 - 4. The location of the sewer stub -out from the building is unknown. The septic tank should; 1) be located down gradient of the home, 2) be buried no deeper than three feet, and 3) at a location accessible for pumping and maintenance at the tank. If COWC can assist with bating the septic tank after the Stub -out location is identified, please call. Vehicular movement over the drain field area during construction should be kept at a minimum to avoid compaction of the receiving soils. Dump trucks and rubber -tire backhoes are to be kept out of the proposed field area. The surface of the field should be seeded after installation of the system. A seed mix such as a "Foothills, Pasture, or Prairie" mix should be sown. These mixes do not require irrigation and may develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the field. If intended use of the site includes support of livestock, the field area should be fenced. INSTALLATION OBSERVATIONS Observation is required prior to backfill. At that time, the septic tank is to be installed with risers on the tank, and inlet and outlet connections properly bedded. The drain field is to be ready for backfill with dispersal pipes in place. Other components such as distribution valves, effluent filters or pump basin will be observed at that time. Our office should be called at 320-898-3434 to observe the installation of the OWS at least 24 hours in advance. One installation observation is required for this design. Installation observations, repeat observations, OWS redesigns, re -staking of drain fields or additional site visit requirements are not included with this design and will be at an additional fee per our service agreement and/or fee schedule. OPERATION AND MAINTENANCE The owner must realize an OWS is different from public sewer service. The owner must assume responsibility for maintenance of the system. The system is relatively maintenance free, but the owner must have the septic tanks pumped. COWC recommends the septic tanks be pumped OWS Design, Job No. e256 9-14-2006, Page 3 every two years and the filter be cleaned after pumping or as needed. The distribution valves control flow of effluent to each section of the field. One section of the field should be closed at a time to allow periodic drying of each segment of the field to extend the life of the field. This can be accomplished by sequentially rotating the valves one or more times year a year. There are also daily considerations, such as not putting plastic or other non -biodegradable material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a malfunctioning toilet can consume in excess of 1000 GPD. An excess 1000 GPD loading could flood and irreparably harm the OWS. COWC cautions against installation of a water softener. The chemical and hydraulic loading from the backwash of a water softener may be detrimental to the OWS and a separate drywell should be constructed for the backwash waste, if a softener is installed. No landscaping or plastic can be used over the field, which will reduce performance of the field. Chemically treated water from a swimming pool or spas should not be introduced into the C7WS. The design of the OWS is based on the treatment of domestic sewage only. No industrial or hazardous wastes should be introduced into the OWS. LIMITAT31ONS An OWS design requires installation by a contractor who is experienced in its installation. Our investigation, layout, design, and recommendations are based on data submitted. If conditions considerably different from those described in this report are encountered, we should be called to observe the conditions. If proposed construction is changed, we should be notified to evaluate the effeet of the ehanges on the OWS. All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, and other specifications that are not depicted in our report are to conform to the requirements of the ISDS regulations. The installer of the system is to be approved by the county health department, and is to have demonstrated knowledge of the ISDS regulations and requirements. If there are questions, please call.

Box 756 Carbondale, Colorado 81623 Subject: OWS Redesign 1380 McLaughlin Lane Lot 28, Reudi Shores Eagle County, Colorado Job No. C256 Mr. Mushet, RECEIVED OCT 10 2006 As requested, CHURCH Onsite Wastewater Consultants, LLC (CQWC) investigated subsurface conditions at the subject site. The purpose of our investigation was to evaluate site conditions and to design an onsite wastewater system (OWS) for a proposed residence. Subsurface con- ditions were investigated and presented in the November 30, 2005 H-P Geotechnical Inc. report. COWC did further subsurface investigation that resulted in revision of the original COWC OWS design dated June 2, 2006. SITE CONDITIONS The site is a 1.12-acre lot located in a rural -residential area in Eagle County, Colorado. The location of the proposed residence is presented on Figure 1. The area of the proposed OWS site slopes moderately, 20-25%, down to the southeast. PROPOSED CONSTRUCTION A 4-bedroom residence is proposed. The residence will be supplied water by an onsite well. The well should be located no less than 100 feet from the drain field of the OWS. The proposed location of the residence is presented on Figures 1 and 2. In accordance with the Individual Sewage Disposal System (ISDS) regulations, the sewage load for a four -bedroom residence is 600 gallons per day (GPD). The peak sewage loading is 900 GPD using a 1.5 peaking factor. SUBSURFACE CONDITIONS Subsurface conditions were investigated and presented in the November 30, 2005 H-P Geotech- nical Inc. report. Subsurface conditions were investigated by digging an exploratory pit in the vicinity of the proposed drain field area. The subsurface conditions consisted of 3 to 3.5 feet of topsoil underlain by relatively stiff, sandy clay with occasional gravel to a depth of 11 feet, the maximum depth of the pit. No free water was observed in the profile pit on November 1 or 2, 2005. Percolation test results indicate percolation rates ranging from 24 to 240 minutes per inch (MPI), with an average of 128 MPI. Percolation tests were conducted by COWC at consistently shallow depths. The Percolation test results indicate percolation rates ranging from 11 to 30 minutes per inch (MPI), with an average of 24 MPI. The percolation test results are presented on Figure 5. A rate of 28 minutes per inch P.O. BOX 527, Wheat Ridge, CO 80034-0527 Voice: 720-898-3434 FAX: 720-898-3455 OWS Design, Job No. C256 10-06-2006, Page 2 was chosen for the design. By designing a drain field in the upper layer of soil the percolation tests conducted by COWL were able to be utilized for the design. This design keeps the drain field above the clay in the lower soil that does not absorb water well. RECOMMENDATIONS The results of our investigation indicate an OWS can be installed at the location presented on Figure 1. A 1500-gallon two -compartment precast concrete septic tank with an Orenco Systems, Inc. (OSI) Model 312 dosing siphon installed in the second compartment is proposed. The field installation includes three 100-foot trenches containing 25 Infiltrator Quick 4 chambers each for a total of 75 chambers. An area of 10 SF was used for each Quick 4 chamber as discussed with Eagle County Health Department. The chambers should be installed a maximum of 146ot below the surface and soil should be mounded on top of the chambers for cover. The maximum 1-Moot excavation is because of the poor percolation rates in the lower layer of clay soil. The OWS should be constructed similar to the details in Figures 2 - 4. The location of the sewer stub -out from the building is unknown. The septic tank should; 1) be located down gradient of the home, 2) be buried no deeper than three feet, and 3) at a location accessible for pumping and maintenance at the tank.

The BELL- PATT system is not a manufactured sewage treatment plant, but an onsite sewage disposal system utilizing septic tank treatment technology with drip Irrigation surface disposal methods. The basis of our request is that there is not nationally -accepted design criteria for the system. This request for certification would allow installation in Colorado when designed by a E.O. CHURCH, INC. a Registered Professional Engineer experienced in the BELL -PAT system function and installed by JIM PATTERSON COMPANY. The BELL= -FAIT system is a dosed, septic tank treatment, drip irtig$tibn sewage system. We anticipate that the system will. be .installed where percolation test results indicate poor percolation ehayracteristics, although it can be installed in standard system criteria areas. The- system utilizes; s. minimum of 1600 gallons of treatment capacity .in: two IDDO gallon 2--Compartment 'septic tanks. The second chamber of the second tank Is used ass -a pump chamber (lift station) from which effluent is dosed to the drip irrigation disposal field. The disposal field includes a minimum of 4 sections of 2-inch perforated distribution pipe trenched to depths of 12- to 30 inches into native soil. Each Sections consists of a level series of distribution pipe. one section i8 rested at all times, to extend the life of the field. The disposal field will be sized based on a combination of the percolation characteristics of the soil and potential evaporation -transpiration at the site A general explanation of BELL -FAT system is presented as APPEl�1Dig A. A copy of a typical design report and calculations are attached as Appendix B. Attached as ' Appendix C is the . OPEIiATIOOA] MAINTERAM (0 and K) letter provided each owser. The 0 and X letter provides emergency phone numbers; and details as to the equipment installed at the site. At this time, 33 BELL-PATT systems have been'desigaed and 25 systems have been installed. The systems have been. Installed in 5 counties, Adams, Axapahoe, Douglas, Elbert, and Jefferson under the Jurisdiction of Elbert, Jefferson and Tri-County Healtb Departments.

UD o APPENDIX A BELL-PATT ONSITB SEWAGE DISPOSAL SYSTEM - Gam, cONDITIONS RAL - The BELL-PATT Onsite Sewage Disposal System (OSpS) Is a dosed septic tank treatment and drip irrigatiom infiltration sewage disposal system. The system is proposed for use in primarily poor percolation soils, although general use is possible, but not typically economically Justifiable. The capability of the system to function in. poor percolation conditions is: 1. the extended treatment in oversized septic tanks, 2. the dosed application of effluent, and _ 3. the relatively shallow drip irrigation dispersal pipes. References and general design and installation criteria are presented below. TREATMENT - Installation: The treatment is by a minimum of twa-1890.. gel -Ion• 2 compart- ment septic tanks. This allows a minimum of 1600 gallons of retention capacity. Larger residences or commercial facilities are sized to a retention capacity of 130% Of state minimum capacities. Operation: Operation and maintenance of the system will require pumping of the septic tanks on a regular schedule. We recommend pumping of the septic tanks at the end of the first year to monitor sludge accumulation and at a minimum of every 2 years afterwards, or as needed sootier. ]LOSING and DISTRIBUTION - From the 2md chamber of the 2nd septic tank effluent will be pumped to the drip irrigation disposal field thru 4 distribution valves. DOSING: DOSING is be done by pumping of effluent from the final chamber of the septic' -tanks. The size of the pump is determined on a site specific basis. Typically the pump will have a 2 inch delivery capacity with horsepower ratings ranging, from 1/3 to 1/2 H.P.. A minimum of 150 gallons per dose will be specified to distribute effluent thru a mintznum of 33Z of the disposal field. The pumps will be specified from readily available, off the shelf, equipment. An alarm system is installed to warn owners of pump failure. Distribution: Distribution of effluent is designed with a minimum of 4 valves. The valves control effluent flow to the fields, so that resting can take place, or a saturated field section can be isolated. A typical detail•of the valve system is attached in Appendix B. Each valve serves a proportionate section of disposal field (maximum of 1/4 of the field area). One section of the disposal field will be unused (resting) at all times to prolong the life of the system. The resting of the section of the field will help degrade any organic matter butidup in the field. DISPOSAL FIELD - Ae disposal field will Consist of a minimum of 4 sections. The section will t tally be 100 feet long along contours. The trenches within each section is installed at a depth of 12 to 30 inches, The section eft be sized to step down a natural slope. The disposal field will be -only installed in native soil. No installation will be allowed when soils are wet because "smearing" of clay soil can occur, which can retard water flow in the soils. Siziax: The disposal field size is determined by. a combination of characteristics of the site which include: percolation rotes, potential evapotranspiration values, slope, ground water conditions, and depth to bedrock. A summary of the application rates for percolation rates is attadh a8 Ta'ble II. An examyle Of a typIasl dispoo*2 field 01=0 for a 3- bcdrooa i ilt'1 it-UiR�ll ii i- ax JUJ f OZU131ju riff ' If CUU,3 S 4 - E i f-. uv ' A- Z r f r residence with a percolation rate of 90 minutes per ineb (!PI) ;would be 3800 square feet (S.F.). The calculations include safety factors of 1.5 for peak loading and 1.6 for a garbage grinder and gashing machines. The area of the drip irrigation disposal field is larger than a comparable sand E-T design area. Installation, The distribution pipe is installed using a trenching machine to excavate an 8 inch trench. Two inch perforated pipe is installed in the bottom of the trench. The trenches are backfilled with native soils. The soils are not compacted, but excess sail is left above the trench to. compensate for settlement of the trench baek€ill. Seeding: We recommend the feeding of the top of the drip irrigation' field with a dryland seed mix which does not require irrigation. There are several seed mixes available locally which are suitable. Example mixes include: Pasture, Foothills, and Dryland. 02eration: The primary limiting condition of the system is that no irrigation can take place above the disposal field. The soil conditions which will. require the use of the BELL -PAT system indicates that subsurface infiltration is limited. Therefore, the addition of surface irrigation will deter the effectiveness of the system. No surface irrigation is allowed over - the disposal field. A copy of operation and maintenance procedures which are given to owners is attached as APPENDIX C. MAINTENANCE - The BELL-PATT system is relatively maintenance free. The septic tanks should be pumped at the and of the first year of use to mouitor sludge accumulatiou and a minim= of every 2 years afterwards. The use of the sections of the disposal fields should be rotated at 6 month intervals:. One section should be drying at all times. If on individual section becomes saturated it can be closed or partially closed and allowed to dry while the "dry" section is ,opened. The only mechanical component is the pump. The pump is a locally available heavy duty pump which will provide long service life. A service label for the system is attached to the alarm. The label includes the pump size and model number and emergency phone numbers to call for service.

The Pitkin County Board of Commissioners has declared in 'the Pitkin Cou tv T i• i ewnap snosal '.--* nLR_eg ation (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. —Me 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 Pitldn 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 eighteen (IS) 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". Feb 20 03 06:o9p .3 Pitkin Co Env. Health i97M920-5077 p.5 2. The Pitkin County Board of Health and the Aspen/Piddn. 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 disposals system shall be . recorded in real estate recordsfor 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/Pitldn 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 Pitldn 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 FCBOH actions on experimental .systems as found. in Section 12-8.1 of the ISDS Regulation. 6. if a `rater 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. g 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 evao#ranspiration/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." F,eb 20 03 06:09p Pitkin Co Env. Health 1970)920-5077 p.6 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 eighteen (18) 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.
