The revision is based on a reorientation of the beds from our April 23, 1999 design letter. This letter should be used in conjunction with our original design. This letter includes two revised figures, Figures 1 and 2. The original Figures 1 and 2 should be removed to avoid confusion. RECOMMENDATIONS - The OWS proposed includes: four septic tanks, three effluent filters, a dosing siphon, and 12 chamber -beds as presented on Revised Figure 1. The OWS design is based on an average sewage loading of 2870 GPD and a percolation rate of 41 MPI. We recommend installation of two 1000 - gallon single -compartment precast concrete septic tanks, one 2000 -gallon single -compartment precast concrete tank, and one 1500 -gallon two-compartment precast concrete septic tank with a dosing siphon in the second compartment. We recommend the installation of twelve chamber -beds, each with 2 rows of 7 chambers. A dosing siphon is required for distribution and to distribute the effluent through the field to increase the efficiency of the field. We recommend a 250 -gallon close per cycle. The proposed OWS is not oversized for section rotation and rotation should not be done. The surface of the drain fields should be seeded. We recommend using a native seed mix. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the fields. No landscaping or plastic can be installed over the fields, which will reduce perfor- mance of the fields. LIMITATIONS - An OWS design requires installation by a contractor who is experienced in its installa- tion. Our investigation, layout, design and recommendations are based on data submitted. If subsurface conditions considerably different from those described in this report are encountered, we should be notified to evaluate the effect on the proposed OWS. If the health department makes modifications to this design, we should be contacted to evaluate the impact on the performance of the OWS. All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank constriction, and other specifications, which are not depicted in our report, are to conform to DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 . • Revised OWS Design Job No. 10777 Page 2 the requirements of the ISDS regulations.

As requested, we have evaluated subsurface conditions at the site and designed an onsite wastewater system (OWS) for the proposed residence. Our firm investigated subsurface conditions on April 13, 1999. SITE CONDITIONS - The lot is located in a rural residential area in Pitkin County, Colorado. The proposed drain field area has a gentle slope of I M There is a moderate cover of native grasses in the proposed field area PROPOSED CONSTRUCTION - A four-bedroom residence greater than 6000 square feet (SF), a two- bedroom caretaker unit/guest house, and pool house, and a garage with a washroom are proposed at the locations presented on Figure 1. We are sizing the OWS based on 8 bedrooms and 1640 Gallons Per Day (GPD) using Aspen/Pitkin Environmental Health Department (APEHD) loading of 130 and 75 gallons per day per person The loading was determined based on individual detached structures. Thk�p e, which has g=W than 6000 SF is proposed to have 4 bedrooms and therefore has a design loading of 130 GPD/person. The estho less than 2000 SF and is proposed as 2 bedrooms ng was based on 75 GPD/perso . was breed on 15 people at 10 GPD/person and 1 -ho was based on 15 people at 10 GPD/person, for a total loading of 300 GPD for the garage and poo Ouse. The sewage loading with a peaking factor of 1.75 is 2870 GPD. This loading includes a dishwasher, gar- bage grinder, and washing machine. The residence will be served by public water. A pool is proposed at the southeast comer of the residence, which should be located 25+ feet from the drain field- SUBSURFACE eld SUBSURFACE CONDITIONS — We performed a subsurface investigation by drilling 8 percolation holes, 37 to 30 inches deep, and two profile holes at the locations indicated on Figure 1. Subsurface conditions in Profile 1 consisted of 1 foot of topsoil underlain by silty, sandy, clay to 7 feet, underlain by sandstone bedrock to the maximum depth explored of 10 $et Subsurface conditions in Profile 2 consisted of 1 foot of topsoil underlain by silty, sandy, clay to 6.5 feet, underlain by sandstone bedrock to the maximum depth explored of 10 feet. Percolation tests indicate percolation rates of 30 to 60 minutes per inch (MPI). The average percolation rate is 4t MPI. DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 90033 I303.463.9317 Fax: 303.463.9321 • O Design No Job No. 10777 Page 2 RECOMMENDATIONS - We recommend the installation of four septic tanks, a dosing siphon, and 6 chamber -bed OWS be installed at the locations presented on Figure 1. The OWS design is based on an average sewage load of 2870 GPD and a percolation rate of 41 MPI. We recommend the installation of two 1000 -gallon and one 2000 -gallon single -compartment concrete septic tanks at the individual structures to be followed by one 1500 -gallon two-compartment precast concrete septic with a dosing siphon in a screened vault in the second compartment, as indicated on Figure 1. The proposed OWS is not oversized for section rotation and rotation should not be done. We recommend the installation of six chamber -beds, each with 2 rows of 14 chambers. A dosing siphon is required to distribute the effluent through the field to increase the efficiency of the field. We recommend a distribution box with flow equalizers be installed to distribute effluent among the beds. We recommend a 250 -gallon dose per cycle. Dosing siphon details are presented as Figure 4. We recommend the surface of the field be seeded after installation of the fields. We recommend using a native seed mix available at seed stores. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the fields. No landscaping or plastic can be installed over the fields, which will reduce performance of the fields. Livestock should not be confined above the fields. OPERATION AND MAINTENANCE - The owner must realize an OWS is different from public sewer service, and must assume the responsibility for maintenance of the OWS. The system is relatively maintenance free, but the owner must have the septic tanks pumped. We recommend the septic tank be pumped and the screened vault be cleaned or "hosed off' every two years. There are daily considerations, such as not putting plastic or other nonbiodegradable material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a run- ning toilet can consume in excess of 1000 GPD. A loading of 1000 GPD could flood and irreparably harm the OWS. We caution against installation of a water softener. The hydraulic loading from the backwash of a water softener may be detrimental to OWS. A separate drywell should be constructed for the backwash waste, if a softener is installed Chemically treated water from a swimming pool or spas should not be intro- duced to the OWS. LIMITATIONS - 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 subsurface conditions considerably different from those described in this report are encountered, we should be notified to evaluate the effect on the proposed OWS. If the health department makes mod- ifications to this design, we should be contacted to evaluate the impact on the performance of 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, which are not depicted in our report, are to conform to the requirements of the ISDS regulations. The installer of the system is to have demonstrated knowledge of the APEHD ISDS regulations and requirements. If there are any questions or if we can be of further service, please call.

But, I didn't want to hold up their permits Please remove from all your design letters your boiler plate language on the second page which addresses if additional bedrooms are planned. It gives the impression that the owner can simply increase the septic at their discretion, which is not the case. We always must insure that the proper setbacks are always maintained. And in Kenner you state in this same paragraph that the system is sized for an 8 -Br residence and this is not quite true. An 8 bedroom residence at 130 gallons/person/day would be larger than what is designed since the design is for a 4 BR and outbuilding with less flow. For the Stone septic, please remove that language also AND please revise you drawing so that it shows equal distribution to the 3 trenches. The design you submitted shows 50% going to the middle trench and 25% going to the two outer trenches.

He said there is an abandoned irrigation ditch close to the area he is putting the leach field. The homeowner also wants to install a pond close to the leach field area. Evidently the application and design (Tim Petz) says there will be 2870 gpd discharge. I told Ty he had to keep the leach field 194 feet from the pond, but could encroach on the abandoned ditch. He said he was going to bulldoze the ditch closed. I told him we would insist on that if the field was next to it without benefit of lining the ditch in case it were ever to be used in the future. He said he can'tut the field in where it is supposed to go if the ditch is operational and the pond is installed. He can't make the setbacks. I couldn't find the permit, but would hope Tim designed the field with proper setbacks. I get the impression he did not do that however. Ty said Tim was going to visit the site Thurs 3/30 morning and wanted you to be there too if you can make it. This is one that you should probably try to see. Ty said he would have a couple of trenches done by then. See me with questions. Thanks, TSD Thomas S. Dunlop, Director Aspen/Pitkin Environmental Health Dept. 130 S.
