Box 70, Silt, Colorado 81652 (970) 876-2353 Office (970) 876-2937 Fax October 17, 2014 Garfield County Community Development Attn: Mr. Glenn Hartmann 108 8'h Street, Suite 401 Glenwood Springs, CO 81601 Re: Referral for Turtle Tracks Resort ISDS within 100 -year floodplain Dear Mr. Hartmann: On October 7, 2014, the Town of Silt reviewed the Turtle Tracks Resort Floodplain Development Permit at its regularly scheduled Planning & Zoning Commission Meeting. The Town of Silt believes that installing an Individual Sewage Disposal System (ISDS) within the floodplain of the Colorado River and upstream of the Town water supply is concerning. As you may be aware, the Colorado Department of Public Health and Environment (CDPHE) replaced ISDS regulations with new Onsite Waste Water Treatment (OWTS) regulations (Regulation # 43) on June 30, 2013. The CDPHE then allotted counties one year to provide their own more stringent regulations or adopt the CDPHE's. The Garfield County Board of County Commissioners (BOCC), sitting as the Board of Health, passed Resolution No. 14-22 on April 14, 2014, which essentially adopted CDPHE Regulation # 43 with an effective date of June 30, 2014. According to the application, the DFE (Design Flood Elevation) is approximately 2.2 feet above the existing ground. The greatest concern is that the applicant is proposing an ISDS (disposal) under the older regulations and not the OWTS (treatment) under the current regulations in an area that has high groundwater that surfaces in early summer, is subject to flooding, and may receive concentrated waste (BODS, TSS and nitrogen) or non-residential waste by transient users. There is also a concern that the leach field is located on top of or within 50' of a jurisdictional wetlands. Regulation #43.8.J states: New OWTS and replacement OWTS installed in a 100 year floodplain shall meet or exceed the requirements of the Federal Emergency Management Agency and the local emergency agency. Repairs of an existing system shall meet the 231 N. 7th Street, P.O. Box 70, Silt, Colorado 81652 (970) 876-2353 Office (970) 876-2937 Fax requirements as feasible. The system as approved by a local public health agency shall be designed to minimize or eliminate infiltration offloodwaters into the system and discharge from the system into the floodwaters. NFIP Unit 5, NFIP Floodplain Management Requirements states: Water and Sewer Systems 44 CFR 60.3(a)(6) [The community must] Require within flood -prone areas (i) new and replacement sewage systems to be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters and (ii) onsite waste disposal systems to be located to avoid impairment to them or contamination from them during flooding The objection of these requirements is to ensure that a building that is protected from flood damage can still be used after the flood recedes. In most instances, these criteria can be met through careful system design. Manholes should be raised above the 100 -year flood level or equipped with seals to prevent leakage. Pumping stations should have electrical panels elevation above the BFE On-site waste disposal systems should be located to ensure they will not release contamination in a flood and can be used after flood waters recede. The first objective should be to locate the system outside the flood hazard area, if that is feasible. A couple of major differences between the ISDS regulations and the OWTS regulations that affect this site and are of concern to the Town are: Vertical setback from groundwater: ISDS = 4', OWTS = 4' (Treatment Level TL1) or 3' with pressure dosing (TL1) or 2' with advanced treatment (TL2N or greater). Setback from wetlands: ISDS = N/A, OWTS = 50 (wetland grasses and shallow groundwater on the site). Given the proximity and upstream location of this system to the Town's only water supply, the Town of Silt would suggest that the system be designed according to the current OWTS regulations (not the outdated ISDS regulations) with the consideration of the 100 -year floodplain elevation as the effective groundwater elevation and with advanced treatment at a level of TL2N or greater. At a minimum, advanced treatment TL2N should be mandated for the site. These precautions should ensure that the groundwater is not contaminated by effluent under daily use and that the river does not received the contaminated soils of the mound when the site does flood. 231 N. 7th Street, P.O.

Sampling Access 43.8 Design Criteria — General 1. If sampling for testing or as a requirement for a permit will be required of effluent from a component other than the soil treatment area, an accessible sampling point shall be provided. 2. If sampling of the treated wastewater from the soil treatment area will be required for testing or as a requirement for a permit, a monitoring well or wells shall be constructed. Monitoring wells shall be located down gradient from the soil treatment area, accessible, and provided with a properly securable cover at or above the ground surface. Monitoring wells up gradient of the system may also be required. Lysimeters or other collection devices under the soil treatment area may be used instead of a monitoring well if approved by the local public health agency or other issuer of a permit. H. Component Operating Instructions 1. The manufacturer of proprietary treatment units utilizing mechanical components shall provide clear, concise written instructions covering the components which, when followed, shall assure proper installation and safe and satisfactory operation and maintenance. 2. If the OWTS uses public domain technology, the design engineer shall provide clear, concise written instructions covering the components which, when followed, shall assure proper installation and safe and satisfactory operation and maintenance. Surface Activity: Activity or use on the surface of the ground over any part of the OWTS must be restricted to that which shall allow the system to function as designed and which shall not contribute to compaction of the soil or to structural loading detrimental to the structural integrity or capability of the component to function as designed. During construction, equipment shall be kept off of the ground surface above the soil treatment area and out of the excavation to prevent compaction. If compaction occurs, the disturbed or compacted soil shall be re-evaluated and new percolation tests may be performed to the disturbed or compacted soil and the system redesigned if the parameters have changed. J. Floodplains 1. New OWTS and replacement OWTS installed in a 100 -year floodplain shall meet or exceed the requirements of the Federal Emergency Management Agency and the local emergency agency.

Based on CDPHE, WQCC On -Site Wasteyv ater Treatment Regulation #43, effective June 30, 2013; the estimate of Average Daily Wastewater Flow (ADWF) for the proposed improvements is: Campground: 50 gpd per campsite Laundry: 400 gpd per self-service commercial washer ADWF = 50 gpd * 10 campsites + 400 gpd * 1 washer = 900 gpd As a non-residential application, the septic tank shall be sized to permit detention of incoming wastewater design flows for a minimum of 48 hours. Therefore, the septic tank size shall be: Septic Tank: 900 gpd * (48 hrs / 24 hrs) = 1,800 gallons (2000 -gallon tank). The associated dosing tank shall be sized for 3 doses per day. Therefore, the minimum dosing tank size shall be 900 gpd / 3 = 300 gallons. As an option, the two tanks could be combined into a single tank. Single tank options are: 1) A 2,500 -gallon three compartment tank which contains at least 1,800 -gallons of combined - storage in the -first two chambers and is equipped with a basic dosing pump arrangement; or 2) A 2,250 -gallon two compartment tank equipped with an approved pump filtering devide to assure that only liquid effluent will be discharged (Orenco ProPak or approved equal).

Dear Thom: VIA E-mail: dpesnichak, aschwaller @garfield —county.com This is WestWater's report of a wetland evaluation performed at your property near Silt, Colorado on July 25, 2007. BACKGROUND Your request for a wetland evaluation was in response to a requirement in a Garfield County Building and Planning Department letter of May 16, 2007: 4. A Section 404 Permit for the day use access road crossing of the Colorado River and the development of the trout pond shall be obtained if the proposed use involves some component of the dredge or fill materia! and then shall be presented to the Garfield County Building and Planning Department prior to the issuance of the Special Use Permit if necessary. The proposed project, as understood by WestWater biologists includes: (1) use of an existing road crossing of the Last Chance Ditch (LCD), (2) construction of a bridge spanning the LC J) to access a day use area and proposed gazebo in the northwest corner of the property, and (3) installation of a culvert in an existing irrigation ditch to allow access on to the LCD bridge. No other project components were examined. WestWater was retained to provide an opinion as to the presence of Army Corps of Engineers (COE) jurisdictional wetlands, and need for an Army Corps of Engineers (COE) 404 permit related to the bridge and culvert. WestWater has performed wetland evaluations and delineations for many years in western Colorado, and has established a very good working relationship with the COE Grand Junction office. METHODS WestWater biologists performed initial wetland evaluation of the subject area. on July 25, 2007. Potential wetland areas were identified utilizing the three parameter method (vegetation, soils and hydrologic indicators) in accordance with Interim Arid West Regional supplement to the Corps of Engineers Wetland Delineation Manual, December 2006. The evaluation included WestWater Engineering Page 1 of 5 July 30, 2007 observations of dominant wetland indicator plant species and soil borings (20+ inches deep) for observation of hydrologic and soils characteristics. Wetland areas in this report are referred to by WestWater as "potential wetlands". Only the COE can confirm wetland areas and boundary lines based on a complete wetland delineation and submittal of a request for Jurisdictional Determination to COE by the project proponent. RESULTS Figure 1 depicts the areas examined by WestWater and Photos 1 and 2 are typical project area views (attached). (1) The existing road crosses the LCD and potential fringe wetlands on both sides of the channel. At the road crossing the banks of the LCD are not as steep as the rest of the ditch and fringe wetlands are 8-10 feet wide from the waters edge. Dominant wetland vegetation indicator species consist of: Phalaris arundinacea (Reed canarygrass), Equisetum spp. (horse tail), and Elaeangnus angustifolia (Russian olive). Wetland soils were saturated and showed redoximorphic features with in the first 12 inches. (2) The LCD has a potential wetland fringe extending up both sides of the bank to the upland terrace. Bank slopes are at an approx. 1:1 slope and the upland terrace is approximately 5 feet. above the ordinary high water mark (see Figure land Photo 1). Fringe wetlands range from 4-6 feet wide from the waters edge. Vegetation, soil, and hydrological findings were consistent with the road crossing area. On the top edge of the bank wetland soil indicators were at 20 inches and faded as distance from the ditch increased. The transition in soil indicators was the primary means of estimating the wetland boundary. (3) The irrigation ditch providing the existing pond with water is controlled by a head gate located across CR 311 from the southern most entrance to the property. From the head gate, the ditch flows under CR 311 across the upland terrace of the property into the existing pond, and continues out of the pond into the LCD as irrigation return flow. The ditch is has a narrow (2 feet wide) wetland fringe on both sides, wetland vegetation is dominated by Scirpus pungens (three -square bulrush) and Scirpus acutus (hard stem bulrush) (Photo 2). Wetland soils were saturated and showed redoximorphic features with in the first 12 inches. The ditch appears to have been entirely constructed in uplands. COE Jurisdictional Issues (1) The existing day use road that crosses the LCD requires no permit as long as no fill activity of any kind takes place within the boundaries of wetland fringe or below the Ordinary High Water mark (OHW) of the Waters of the US (WOUS). WOUS generally includes rivers, streams, lakes and related wetlands. (2) The proposed bridge spanning the LCD requires no permit as long as wetland areas are not disturbed during construction. Abutments must be placed outside of the wetland and in upland. No fill (even temporarily) can be placed within the wetlands or the OHW mark of the Relatively Permanent Waters (RPW). Relatively Permanent Waters of the US refer to waters that are un- navigable but are adjacent to waters of the US and flow for at least 3 months of the year. WestWater Engineering Page 2 of 5 July 30, 2007 (3) The irrigation ditch providing the existing pond with water is located on the upland terrace. In addition, the proponent can control the flow via a head gate and the flow can be entirely shut off. Based on this, we believe that the irrigation ditch is likely to be considered non - jurisdictional by COE, even thought all three wetland parameters are present. Therefore the placement of a culvert in the irrigation ditch would not require a permit. Please feel free to contact our office if you have any questions regarding this evaluation, or if we can be of assistance in any way. Sincerely, Brett F.
