This design has been prepared subsequent to the Engineering Report and Site Application submitted on November 12, 2001. CHURCH & Associates, Inc (CHURCH) completed an Engineering Report for Application for Site Approval (Site Application report), dated December 15, 2002 with an Addendum to this report, dated April 21, 2003. The Technical Sheets attached with this design report are presented in the format that has been developed for CDOT for this project. The other sheet numbers not presented in this design report are not applicable to the proposed WTF, but are applicable for the other construction work proposed at the Rest Area. SITE DESCRIPTION The CDOT Bair Ranch Rest Area is located in Glenwood Canyon, in the NE 1/4, SW 1/4, Section 15, Township 5 South, Range 87 West in the 6th P.M, on the north side of the Colorado River. The rest area is currently served water by a well. Wastewater is currently treated by an Individual Sewage Disposal System (ISDS) with subsurface discharge into the environment. The wastewater system was designed and installed in 1990's with composting toilets and effluent discharging to septic tanks and drain field. The drain field was upgraded in the late 1990's, but does not have adequate capacity for flush toilets. Onsite Wastewater System Job No. 12090 July 9, 2003 Page 2 The base reference geologic map for the area is the Open File Map 95-4, Geologic Map of the Shoshone Quadrangle, Garfield County, Colorado, by the Colorado Geologic Survey, dated 1995. The rest area is located on a gentle south -facing slope, underlain by stream -channel, floodplain, and low -terrace deposits (Qa). The area has variable depths of fill at the surface associated with the construction of I-70. PROPOSED TREATMENT SYSTEM For primary treatment, the proposed wastewater system will consist of two existing 2,000 -gallon septic tanks and lift station receiving raw sewage from the existing rest area restrooms. The effluent will be pumped to a new 9,000 -gallon septic tank. For secondary treatment, the effluent will flow by gravity from the new septic tank to a 4,000 -gallon recirculation tank where effluent pumps installed in this tank will discharge effluent (by timed dosing) to the surface of 12 packed -bed filter (PBF) units. Effluent will be recirculated through the PBF units 5 times prior to discharge. The effluent will be directed to an ultraviolet (UV) disinfection system before discharge to the Colorado River. DESIGN CRITERIA Preliminary Discharge Limits: Preliminary limits were requested from the Colorado Department of Health and the Environment (CDPHE) Water Quality Control Division, and have been received in their letter of January 29, 2002 as attached in Appendix A. The river is classified as a Cold Water Aquatic Life, Class la, Existing Primary Contact Recreation, Agriculture and Water Supply Stream. The preliminary effluent discharge limits are summarized below: BOD5, mg/1 BOD5, % removal TSS, mg/1 TSS, % removal Oil/Grease (mg/1) pH, s.u. Fecal Coliform, org./100 ml Total Residual Chlorine, mg/1 Onsite Wastewater System Job No. 12090 July 9, 2003 Page 3 30 (30 -day average), 45 (7 -day maximum) 85% (30 -day average) 30 (30 -day average), 45 (7 -day maximum) 85% (30 -day average) 10 (maximum) 6.5-9.0 (minimum -maximum) 6,000 (30 -day average), 12,000 (7 -day average) 0.5 (daily maximum) Estimated Wastewater Flows: Wastewater flows have been estimated by monitoring the current and projected usage of the Bair Ranch Rest Area and adjusting the per person wastewater generation according to usage at the No Name rest area. The No Name rest area has similar flush toilets as proposed for the Bair Ranch Rest Area (See Report for Site Application Approval dated November 12, 2001). This WTF design is based on a sewage flow of 3,300 GPD. SEPTIC TANKS In accordance with the CDPHE ISDS Guidelines, the septic tank volume shall provide for a minimum retention of incoming sewage for 30 hours (1.25 days). At 3,300 GPD, the minimum septic tank volume required is calculated as: Volume(minimum) = 3,300 GPD X 1.25 days = 4,125 Gallons However, the Rest Area facility will have toilets as the primary wastewater generator. In this case, toilet paper will build up at a rate greater than it can be digested in a septic tank sized at the minimum volume, and will dramatically decrease the total effective septic tank volume. According to reference literature and manufacturers recommendations, sizing the minimum septic tank volume at approximately 3 to 4 times the design flow volume will allow for Onsite Wastewater System Job No. 12090 July 9, 2003 Page 4 additional settling and anaerobic digestion, and less frequent pumping. Therefore, using the two existing 2,000 -gallon septic tanks and including a new 9,000 -gallon septic tank is recommended.. This will provide a total septic tank volume of 13,000 gallons. The new 9,000 -gallon tank will be equipped with access manholes for scum and sludge level measuring and pumping. In addition, the new septic tank will be equipped with two 12 - inch -diameter effluent filters at the outlet to screen the effluent before draining to the Recirculation Tank. RECIRCULATION TANK In accordance with the referenced literature, the recirculation tank is to be sized at one times the average daily flow. A minimum tank capacity is 3,330 gallons. The installation of one 4,000 -gallon tank is proposed. A duplex pumping system is to be located in the recirculation tank, and be controlled by a programmable timer in the control panel. An alternating relay in the panel will sequence the pumps. These pumps are a part of a pre-packaged system selected for this WTF design. Pump tinier settings will be adjusted to provide a recirculation ratio of 5:1 through the textile PBF units. With monitoring of influent flows, the timer can be adjusted to accommodate the actual wastewater flows. TEXTILE PACKED -BED FILTERS Septic tank effluent is to be applied to the surface of the PBF units at a rate of 15.5 gallons/day/ft2. Each PBF unit has 20 square feet of surface area. AREA REQUIRED(minimum) = 3,330 GPD - 15.5 GPD per ft2 _ 20 ft2/unit = 10.6 PBF units Onsite Wastewater System Job No. 12090 July 9, 2003 Page 5 A total of 12 PBF units for a total surface area of 240 ft2 is proposed. Each unit is 2.6 feet deep with an underdrain pipe below the textile media for effluent collection. Effluent will be distributed across the surface of the filters with small diameter, pressure distribution piping systems. The PBF units will be alternately dosed on the order of 1 to 2 minutes per dose to provide the "micro dosing." Micro -dosing is necessary to reduce the effects of peak flows and provide a high level of nitrification and organic removal. As stated previously, the system will be set to pass the septic tank effluent through the PBF units 5 times prior to discharge to the disinfection system. DISINFECTION SYSTEM The use of ultraviolet (UV) disinfection prior to discharge to surface water is proposed. This type of non -chemical disinfection is proposed to eliminate the discharge of chemicals and/or their byproduct to the surface water. The UV disinfection unit will be housed in a small building. The proposed building is not a part of this WTF design report and will be design ed by others. The ultraviolet light disinfection will be sized to provide greater than 99.9% bacterial reduction with a fecal coliform count of less than 200 per 100 ml. This is less than the 6,000 per 100 ml allowed by the preliminary discharge limits. The UV disinfection system will consist of two UV lamps, each in a separate housing, and will be operated in series. The UV lamps selected for this design are rated at a maximum capacity of 40 GPM each (or 80 GPM total). The effluent pumps in the recirculation serving the PBF units have been sized to deliver approximately 43 GPM each. If both pumps were activated at once (an unusual peak event), then the flow rate to the PBF units would be 86 GPM. However, when the splitter valve buoy is fully seated, only 20% of the return flow will be discharged to the disinfection system. Therefore, the maximum flow rate to the UV disinfection unit is 0.2 x 86 Onsite Wastewater System Job No. 12090 July 9, 2003 Page 6 GPM or 17.2 GPM. This flow rate is below the maximum flow recommended for a single UV disinfection lamp. Toilet waste will be the predominant source for wastewater flows and the rest area. Based on engineering experience, high strength wastes of this type can result in effluent that is darker in color than that observed from a typical domestic wastewater source. For darker colored effluent, the manufacturer recommends sizing of the UV system based on at twice the maximum flow (i.e. 2 x 17.2 GPM), or 34.4 GPM. This flow is also less than the maximum flow recommended for one UV lamp. Two UV lamps will be installed for redundancy, in the event that one UV lamp was to malfunction. The UV system will be equipped with a monitoring system to warn of UV lamp failure. One spare UV lamp is to be kept onsite at all times. The UV disinfection system should be housed in a l0 -foot by 10 -foot (minimum) building. ELECTRICAL REQUIREMENTS The electrical components for the pumping systems and UV disinfection system are to be located at the UV building. The specific voltage requirements for individual components are presented in attached Technical Sheets FLOW MONITORING Influent flow monitoring from such small, highly variable flows is problematic, Since the seasonal use of the rest area will fluctuate, it is proposed to monitor influent flow from the Rest Area restroom building water system. A cumulative flow meter must be installed on the well Onsite Wastewater System Job No. 12090 July 9, 2003 Page 7 serving the restroom building. Water meter readings from the odometer -type totalizer meter are to be recorded weekly, at a minimum. Effluent flow monitoring will be performed with the use of another cumulative flow meter down gradient from the disinfection unit. Meter readings must be recorded on a daily basis. CONSTRUCTION In addition to the installation of WTF components as detailed in this report, the contractor will be responsible for the extension of electrical and water services, as applicable, to the WTF. Electrical and water supply details are to be designed by others. All wiring is to be completed by a licensed electrician in accordance national and local codes. A pre -construction meeting is to take place at the site with the Contractor, Turner, Collie & Braden, Inc., CHURCH & Associates, Inc., and Health Department representatives as applicable. At this time, additional project details will be discussed. Details include: exact wastewater system component elevations, locations, time estimates for completion of various phases of the project, and installation observations by CHURCH & Associates, Inc. Upon completion of the installation of the treatment system, the site is to be returned to its original condition as much as practical. Disturbed drive and parking areas are to be resurfaced to existing conditions. Final grading is to be performed to minimize ruts or berms and to provide positive drainage away from wastewater system components. Excess debris, stumps, piping, construction lumber, etc. are to be hauled offsite and disposed of by the contractor. Onsite Wastewater System Job No. 12090 July 9, 2003 Page 8 OPERATION AND MAINTENANCE Operation and maintenance manuals are to be provided by equipment suppliers upon completion of the project.

Church and Associates, Inc. 4501 Wadsworth Blvd. Wheat Ridge, CO 80033 RE: Proposed Bair Ranch Rest Area, Garfield County Dear Mr. Church: Colorado Department of Public Health and Environment The Colorado Department of Public Health and Environment, Water Quality Control Division, has completed your request for preliminary effluent limits (PELs) for the proposed Bair Ranch Rest Area's wastewater treatment plant (WWTP). Your current proposal is for a WWTP with a hydraulic design capacity of 0.005 million gallons per day (MGD). This proposed facility would discharge into the Colorado River in the SE1/4 of NE1/4, Section 15, Township 5 South, Range 87 West of the 6th P.M. in Garfield County. This portion of the Colorado River is identified as stream segment COUCUC03, which means the Upper Colorado River Basin, Upper Colorado River Subbasin, Stream Segment 3. This stream segment is composed of the "Mainstem of the Colorado River from the outlet of Lake Granby to the confluence with the Roaring Fork River." These identifications are found in the Classification and Numeric Standards for Upper Colorado River Basin and North Platte River (Planning Region 12). Effluent limits for specific constituents are based on the type of peiuiit a facility will require after construction. The Bair Ranch Rest Area WWTP may be covered by a general permit. The preliminary effluent limitations were developed for the Bair Ranch Rest Area WWTP based on effluent limits established in the Regulations for Effluent Limitations for a WWTP consisting of a mechanical wastewater treatment process, as well as the water quality -based effluent limits necessary for protection of the water quality of the Colorado River. A PELs evaluation is attached to document the findings and decisions that were used to derive the PELs in Table 1. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Proposed Bair Ranch Rest Area Edward Church January 29, 2002 Page 2 Pi mrncnrl Table l' Tn .�. .. g 11 1tu11L111\LJ 1, L'11 LN T1 TT 11 „.. ..� ,..ytl ' iillitS for Discharge to theColoraod River BODS (mg/1) 45 (7 -day average), 30 (30 -day average) BODS (% removal) 85 (30 -day average) TSS, mechanical plant (mg/1) 45 (7 -day average), 30 (30 -day average) TSS, mechanical plant only (% removal) 85 (30 -day average) TSS aerated lagoon system (mg/1) 75 (7 -day average), 110 (30 -day average) Oil and Grease (mg/1) 10 (maximum) pH (s.u.) 6.5-9.0 (minimum -maximum) Fecal Coliform (organisms/100 ml) 12,000 (7 -day average), 6,000 (30 -day average) Total Residual Chlorine (mg/1) 0.5 (maximum) The limitations in Table 1 apply to all the hydraulic capacities requested.

Introduction The water quality assessment (WQA) of the Colorado River near the Bair Ranch Rest Area Wastewater Treatment Facility (WWTF) was developed for the Colorado Department of Public Health and Environment (CDPHE) Water Quality Control Division (WQCD). The WQA was prepared for Preliminary Effluent Limits (PEL) to facilitate issuance of the Colorado Discharge Permit System (CDPS) permit for the Bair Ranch Rest Area WWTF, and is intended to determine the assimilative capacities available to the Bair Ranch Rest Area WWTF for pollutants found to be of concern. Figure 1 on the following page contains a map of the study area evaluated as part of this WQA. The Bair Ranch Rest Area WWTF discharges to the Colorado River. The ratio of the low flow of the Colorado River to the Bair Ranch Rest Area WWTF design flow is 87922:1. The nearest upstream and downstream facilities had no impact on the assimilative capacities available to the Bair Ranch Rest Area WWTF. Analyses thus indicate that assimilative capacities are very large. Infollnation used in this assessment includes data gathered from the WQCD Station 46, located 8 miles upstream of the WWTF outfall on the Colorado near Dotsero. The data used in the assessment consist of the best infoiniation available at the time of preparation of this PEL analysis.

Water Quantity The Colorado Regulations specify the use of low flow conditions when establishing water quality based effluent limitations, specifically the acute and chronic low flows. The acute low flow, referred to as 1E3, represents the one -day low flow recurring in a three-year interval. The chronic low flow, 30E3, represents the 30 -day average low flow recurring in a three-year interval. Low Flow Analysis To determine the low flows available to the Bair Ranch Rest Area WWI}, USGS gage station 09070500 (Colorado River near Dotsero, CO) was used. This flow gage provides a representative Annendix A Pao -f,,5 of 1( n i P-c/')nn' 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Bair Ranch Rest Area I WWTF Water Quality Assessment PEL measurement of the upstream flow because there are no diversions or confluence of significance between the flow gage and the facility. Daily flows from the USGS Gage Station 09070500 (Colorado River near Dotsero, CO) were obtained and the annual 1E3 and 30E3 low flows were calculated using U.S. Environmental Protection Agency (EPA) DFLOW software. The output from DFLOW provides calculated acute and chronic low flows for each month. Flow data from January 1, 1990 through September 30, 2000 were available from the gage station. The gage station and time frames were deemed representative of current flows and were therefore used in this analysis. Based on the low flow analysis described previously, the upstream low flows available to the Bair Ranch Rest Area WWTF were calculated and are presented in Table A-5.

Technical Analysis In -stream background data and low flows evaluated in Sections II and 11 f are ultimately used to determine the assimilative capacity of the Colorado River near the Bair Ranch Rest Area WW 1,F for pollutants of concern. For all parameters except ammonia a technical analysis of stream assimilation capacity uses the annual low flow (lowest of the monthly low flows) as calculated in the low flow analysis. For ammonia, it is the standard procedure to determine assimilative capacities for each month using the monthly low flows calculated in the low flow analysis, as the regulations allow the use of seasonal flows when establishing assimilative capacities. The assimilative capacity analysis consists of steady-state mass -balance calculations for most pollutants, and modeling for other pollutants such as ammonia. A mass -balance equation is used to calculate the maximum allowable concentration of pollutants in the effluent, and accounts for the upstream concentration of a pollutant at the existing quality, critical low flow (minimal dilution), effluent flow and the water quality standard. The mass -balance equation is expressed as: where: M2 = M3Q3 —M1Q1 Q2 Q,= Upstream low flow (1E3 or 30E3) Q2= Average daily effluent flow (design capacity) Q3 =Downstream flow (Q1 + Q2) MI= In -stream background pollutant concentrations at the mean M2= Calculated maximum allowable effluent pollutant concentration Annendix A Pao-aAof1(l i,m / /' ruv Bair Ranch Rest Area I WWTF Water Quality Assessment PEL M3 = Maximum allowable in -stream pollutant concentration (water quality standards) Pollutants of Concern The following parameters were identified by the WQCD as pollutants of concern for this facility: • Total Ammonia • Fecal Coliform • Total Residual Chlorine. • PH • TSS • BOD5 • Oil and Grease There are no numeric in -stream water quality standards for BOD5, TSS, and oil and grease. Thus, assimilative capacities for these parameters are not calculated in the PEL assessment. Appropriate effluent limitations for these parameters will be set by CDPS effluent limit guidelines. Based upon the size of the discharge, the lack of industrial contributors, dilution provided by the receiving stream and the fact that no unusually high metals concentrations are expected to be found in the wastewater effluent, metals are not evaluated further in this water quality assessment. Bair Ranch Rest Area WWTF: The Bair Ranch Rest Area WWTF is located at SE1/4, NE1/4 Section 15, T5S, R87W, 6th P.M. in Garfield County. The current design capacity of the facility is 0.005 MGD (0.008 cfs). Wastewater treatment is proposed to be accomplished using a mechanical wastewater treatment process. The technical analyses that follow include assessments of the assimilative capacity based on this design capacity. Nearby Sources An assessment of nearby facilities based on WQCD's Permit Tracking System database found 2 current dischargers to the Colorado River in Glenwood Springs downstream of the Bair Ranch Rest Area. The City of Glenwood Springs WWTF (CO -0020516) and Glenwood Hot Springs (CO - 0000141), and 2 other proposed CDOT rest area discharges downstream of the Bair Ranch Rest Area (see Fig. 1). There are current instream temperature standards and effluent temperature limit guidelines being discussed by a workgroup of the WQCD. This may affect the Glenwood Hot Springs effluent limits, but the Bair Ranch Rest Area discharge will not affect these issues. Because of the large available dilution, domestic nature of the other facilities discharges, and the fact that other facilities are located far enough away from the proposed Bair Ranch Rest Area WWTF, these facilities were not further considered in this analysis. Based on current available information, there is no indication that non -point sources were a significant source of pollutants of concern in this area. Any upstream non -point sources were considered in the assessment of the upstream water quality. Chlorine: The mass -balance equation was used to determine the assimilative capacity for chlorine. There are no point sources discharging total residual chlorine within one mile of the Bair Ranch Rest Area WWTF. Because chlorine is rapidly oxidized, in -stream levels ofresidual chlorine are detected only for a short distance below a source. Ambient chlorine was therefore assumed to be zero. Using the mass -balance equation provided in the beginning of Section IV, the acute and chronic low flows set out in Section III, the chlorine background concentration of zero as discussed above, and Annen(ii-v A Pana 7 .,f 1 n F n i i, -)i ->nn', 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Bair Ranch Rest Area I WWTF Water Quality Assessment PEL Parameter Q 1 (cfs) Q 2 (cfs) Q 3 (cfs) M1 (mg/l) M3 (mg/l) M2 (mg/l) Acute Chlorine 473 0.01 473 0 0 1167 Chronic Chlorine 677 0.01 677 0 0 967 the in -stream standards for chlorine shown in Section II, assimilative capacities for chlorine were calculated. The data used and the resulting calculations of the allowable discharge concentration, M2, are set forth below. Fecal Coliform: There are no point sources discharging fecal coliform within one mile of the Bair Ranch Rest Area WWTF. Thus, fecal coliform assimilative capacities were evaluated separately. It is the standard approach of the WQCD to perform a mass -balance check to determine if fecal coliform standards are exceeded. WQCD procedure specifies that checks are conducted using only the chronic low flow as set out in Section III. Using the mass -balance equation provided in the beginning of Section IV, the background concentration contained in Section II, and the in -stream standards for fecal coliform shown in Section II, checks for fecal coliform were conducted. The data used and the resulting calculations of the allowable discharge concentration, M2, are set forth below. Parameter Q1 (cfs) Q 2 (cfs) Q 3 (cfs) M1 (#/100 M3 (#/100 M2 (#/100 ml) MO mi) Fecal Coliform 677.00 0.01 677.0 10 200 16, 705,395 Ammonia: Ammonia is present in the aqueous environment in both ionized and un -ionized forms. It is the un -ionized form which is toxic and which is addressed by water quality standards. The proportion of total ammonia present in un -ionized foam in the receiving stream is a function of the combined upstream and effluent ammonia concentrations, and the pH and temperature of the effluent and receiving stream, combined. Using the mass -balance equation provided in the beginning of Section IV, the acute and chronic low flows set out in Section III, the mean ammonia background concentration shown in Section II, and the in -stream standards found in the Colorado Total Maximum Daily Load and Wasteload Allocation Guidance and the CDPS Summary of Rationale General Permit for Domestic Wastewater Treatment Facilities that Discharge to Receiving Waters with a Chronic Low Flow: Design Flow Ratio of 100:1 or Greater for M3, assimilative capacities for chronic total ammonia were calculated. The data used and the resulting calculations of the allowable discharge concentration, M2, are contained in Table A-6. r 1 1 Appendix A Page 8 of 10 F.

Antidegradation Review As set out in The Basic Standards and Methodologies of Surface Water, Section 31.8(2)(b), an antidegradation analysis is required except in cases where the receiving water is designated as "Use Protected" where the full assimilative capacity of a receiving water may be used, or "Outstanding Waters" where no degradation of a receiving water is allowed. According to the Classifications and Numeric Standards for Upper Colorado River Basin and North Platte River Basin (Planning Region 12), stream segment COUCUCO3 is Undesignated. Thus, an antidegradation review may be conducted for this segment if new or increased impacts are found to occur. However, the ratio of the flow of the Colorado River to the Bair Ranch Rest Area WWTF design flow is 87922:1 at low flows. Section 31.8 (3)(c) specifies that the discharge of pollutants should not be considered to result in significant degradation of the reviewable waters if the flow rate is greater than 100:1 dilution at low flow. Thus, condition 31.8(3)(c) of the regulations is met and no further antidegradation evaluation is necessary. VI.

Careless activity or operation of equipment can cause death, serious personal injury or property damage. 1.2. GENERAL 1.2.1. Itis important to follow the procedures and instructions in this manual in order to safely and properly install a Xerxes fiberglass underground wastewater tank (subsequently referred to as 'tank"). 2 Failure to follow these instructions will void the tank warranty and may cause tank failure, serious personal injury or property damage. 1.2.2. The Xerxes warranty applies only to a tank installed according to these instructions. Since Xerxes does not control the parameters of any installation, Xerxes' sole responsibility in any installation is that presented in our warranty. 1.2.3. It is the responsibility of the owner and operator to always follow the operating guidelines set forth in Xerxes' applicable warranty and Section 16 of this Installation Manual. AXerxes warranty is found in the product brochure or is available upon request from the UST coordinator at the Xerxes plant nearest you. It is the responsibility of the owner to retain this Installation Manual for future reference to operating guidelines. 1.2.4. Use the Tank Installation Checklist (included in this manual) for all tanks as the installation proceeds. Retain a copy of the completed Tank Installation Checklist, and any correspondence, certification, etc., related to the tank. Each tank requires a separate Tank Installation Checklist. Consult your Xerxes representative or distributor if additional Tank Installation Checklist forms are needed. 1.2.5. The tank owner and/or installing contractor should retain a copy of the Tank Installation Checklist to facilitate any warranty claim. 1.2.6. Comply with all applicable regulations and standards, such as: • federal, state and local construction, health, safety and environmental codes; and • industry standard practices. 1.2.7. For additional information, contact your state, county and city storage -tank authorities, including health, fire or building departments, and environmental agencies. All work must be performed according to standard industry practices and OSHA regulations. 1.2.8. Federal, state and local codes and regulations always take precedence over a Xerxes requirement. 1.2.9. Xerxes must authorize — in writing and prior to tank installation — any variation to, or deviation from, these Installation Manual instructions. 1.2.10. All correspondence regarding variations must be retained for any warranty claim to be valid. 1.2.11.

Although Xerxes tanks are rugged, care must be taken so they are not dropped or damaged during delivery, unloading and handling on the job site. 2.1.1.1. When unstrapping the tank from the truck, make sure that the tank is secured in such a way that it does not roll off the truck. 1 A WARNING Do not release straps securing the tank to the truck until lifting equipment (such as a crane) is secured to the tank's lifting lug(s). Failure to do so could result in death or serious injury. AL WARNING Always chock the tank. The tank is heavy and has a large surface area. The tank will roll on sloped surfaces and could be blown about by the wind. Movement of the tank could result in death or serious injury. 2.1.2, Before the tank is unloaded or relocated on the job site (and before preinstallation testing at job site), complete the following steps: 2.1.2.1. Visually inspect the entire exterior surface of the tank to make sure that no shipping or handling damage has occurred. Look particularly for holes, cracks or deep scrapes. 2.1.2.2. Sign the shipping papers accepting the tank as delivered. 2.1.2.3. Be sure that all equipment used to lift the tank is rated to handle the load. Refer to the Tank Handling Data section at Ithe end of the Installation Manual to determine the weight of the tank and to select the proper lifting equipment. I2.1.2.4. Select a solid, level area to place the tank, and clear that area of all rocks, trash and debris. 2.1.3.When hoisting the tank, follow these instructions: (See FIGURE 2-1 and FIGURE 2-2.) 2.1.3.1. When the tank is not rotated (the tank is upright), use all lifting lug(s) to unload and install the tank. 2.1.3.2. Some tanks are rotated on the truck for shipping purposes and some rotated tanks have extra lifting lug(s) to aid In the loading/unloading process. If the tank is rotated on the 3 truck, determine if extra lifting lug(s) are provided for this purpose and then use the following procedures: 2.1.3.2.1. When the tank is rotated but does not have extra lifting lugs, use all lifting lugs to unload and install the tank. 2.1.3.2.2. When the tank is rotated and has extra lifting lugs, use all lifting lugs that are situated on top of the tank in its rotated position to unload the tank. To install the tank, use all lifting lugs that are situated on top of the tank in its upright position. FIGURE 2-1 Top of tank in upright positon Lifting lugs to be used when tank is in upright positon Top of tank in rotated position on truck Lifting lugs to be used when tank is in rotated positiion FIGURE 2-2 2.1.3.3. Do not wrap chain or cable around the tank. 2.1.3.4. Use guy ropes to guide the tank when needed. 2.1.3.5. Do not roll the tank to move it. 2.1.3.6. When handling a tank with a bottom sump or fitting, always take extra care so that the bottom sump or fitting is not damaged. 2.1.4. Whenever a tank is stored at the site, chock it in place to prevent rolling. (See FIGURE 2-3.) Tie the tank down if high winds are expected. Sandbags Tank r Tie Downs Tres FIGURE 2-3 3. PREINSTALLATION INSPECTION 3.1. INSPECTION 3.1.1. Xerxes tanks are inspected prior to shipment, but the tank must also be inspected at the site prior to installation in order to verify the absence of shipping and handling damage. 3,1.2. Thoroughly inspect the outside of the tank for signs of damage. Rotate or lift the tank to inspect the bottom of the tank. A WARNING Always secure the tank before moving or lifting it. This is commonly done by connecting a crane or backhoe to the lifting lugs. Failure to do so could result in death or serious injury. A WARNING While moving or lifting the tank, do not position any part of your body underneath the tank. This could result in death or serious injury. CAUTION /f the tank is to be water tested, it must be supported by backfill on all sides to at least the spring line (middle) of the tank. Failure to do so may result in property damage. (See Section 10.) 3.1.3. If damage is detected, do not attempt repairs. Contact the UST coordinator at the Xerxes plant nearest you. Telephone and fax numbers are found on the back cover of this manual. 4. OPTIONAL PREINSTALLATION TESTING (FOR SEPTIC TANKS FACTORY -EQUIPPED FOR PRESSURE TESTING) NOTE: This section applies only to septic tanks equipped at the manufacturing facility for pressure testing. If you are installing any other Xerxes wastewater tank, proceed to Section 5. 4.1. BEFORE TESTING THE TANK 4.1.1. Xerxes testable septic tanks are tested prior to shipment, but the tank may be retested at the site prior to installation in order to verify the absence of shipping and handling damage. 4.1.2. The tester is responsible for verifying that all of the test equipment is in good working condition, and is properly configured and calibrated. 4.1.3. Construct a test manifold with two air -supply gauges as shown in FIGURE 4-1. Each air -supply gauge must have a maximum full-scale reading of 15 psig with 114 -Ib. or 1/10 -lb. increments, and a pressure -relief device set at 6 psig. Air -Supply Gauge Aft -Supply Valve Air -Supply Gauge Pressure -Relief IDevice FIGURE 4-1 4 4.1.4. During air tests, variation in temperature could be a factor for changes in gauge readings. 4.1.5. It is the installers responsibility to select a thread sealant that is compatible with the product being stored. Some sealants cannot be used with some products. Remove, clean and redope all factory-fumished temporary plugs with appropriate thread sealant. Install permanent plugs in all openings where piping will not be installed. When applicable, make sure all manway bolts are tightened, and fitting plugs are properly doped and sealed. 4.1.6. When checking the tank for leaks during an air/soap test, rotate the tank to check the bottom. 4.1.7. Before rotating the tank during an air/soap test, place protective material on the area on which the tank will be rotated. Make sure the area is flat and is free of large or sharp objects, such as rocks, which may damage the tank. 4.1.8. Rotate the tank slowly and carefully to avoid developing too much momentum. Momentum can grow because fittings on top of the tank make it top heavy. Make sure the tank's fittings and access openings never touch the ground. Do not rotate the tank more than 120° from the initial starting point. A WARNING Always secure the tank before moving or lifting it. This is commonly done by connecting a crane or backhoe to the lifting lugs. Failure to do so could result in death or serious injury. A WARNING While moving or lifting the tank, do not position any part of your body underneath the tank. This could result in death or serious injury. A WARNING Do not lift or hoist a tank under pressure. This could result in death or serious injury. 4.1.9. If damage is detected, do not attempt repairs. Contact the UST coordinator at the Xerxes plant nearest you. Telephone and fax numbers are found on the back cover of this manual. 4.1-.10. After installation and before backfilling to grade, testing may be repeated to verify that no damage has occurred during installation. A WARNING When the tank is under pressure, the access openings and/or fittings may dislodge, or the tank could rupture and result in death or serious injury Before beginning the test, notify all people on the test site to remain in a safe location. ALWAYS ATTEND TO THE TANK DURING THE TEST Stand clear of access openings, fittings and tank ends during the test. A WARNING The maximum test pressure is 5 psig. Position the pressure gauge so that the pressure readings can be clearly read at all times. Failure to follow this warning could result in death or serious injury. (See FIGURE 4-2.) 1 1 1 1 1 1 1 1 1 1 1 1 1 1 imi um FIGURE 4-2 A WARNING The pressure -relief device or regulated air source must be rated at a maximum of 6 psig to reduce the risk of overpressurizing the tank. Failure to follow this warning could result in death or serious injury. 4.2. TESTING THE TANK 4.2.1. Remove all temporary service -fitting plugs. 4.2.2. Redope fittings and install plugs in all openings, except one service fitting (needed for the test manifold). Follow instructions in Point 4.1.5. 4.2.3. Install the test manifold in the NPT threaded coupling of the influent pipe. Use an NPT reducer bushing as necessary. Connect the pressure source to the test manifold. See FIGURE 4-1 and FIGURE 4-3, Access Riser Pipe Threaded Coupling FIGURE 4-3 4.2.4. Pressurize the tank to 5 psig. Allow the pressure to stabilize by adding or removing air as necessary. 4.2.5. Close the air -supply valve on the test manifold. Disconnect the air -supply line. 4.2.6. Soap the entire exterior of the tank, checking for leaks. (Follow instructions in Points 4.1.6. through 4.1.8., including Warnings following 4.1.8.) Watch for active air bubbles, which indicate a leak. Pay -special attention to fittings and access openings. 4.2.7. Monitor the pressure for one hour. 4.2.8. When the test is complete, carefuiiy release the air pressure from the tank by opening the air -supply valve. 4.2.9. When airflow stops, remove the test manifold. 4.3. AFTER TESTING THE TANK 4.3,1. To put the tank in service, both the caps and/or threaded coupling on each pipe end must be cut off. The domed cap inside the access riser may need to be cut off. NOTE: The tank can not be pressure tested after the openings are cut. Therefore, complete all tests before cutting the openings. 5 4.3.2. If not needed, cut off the cap or threaded coupling from each pipe end so that service pipes can be added. Cut as close as possible to the pipe cap or threaded coupling. See FIGURE 4-3. NOTE: The access riser cap is designed to allow the opening inside the riser access to have either an internal flange or no flange at all. 4.3.3. On the domed cap inside the access riser, mark a circle to signify the area that needs to be cut out. See FIGURE 4-4. Domed Cap (Shaving Cut Out) Access Riser Internal Flange Access Opening FIGURE 4-4 4.3.4. Drill a one -inch hole at the marked circle and insert the blade of an appropriate saw into the hole. 4.3.5. With the saw, cut out the domed cap of the access riser, leaving a minimum of 1/2 inch around the inside rim of the access riser (two inches for an internal flange). 5. BACKFILL MATERIAL 5.1. GENERAL 5.1.1. Xerxes tanks must be installed using either pea gravel or crushed stone as backfill material. 5.1.2. Using other than approved bedding and backfill materials without prior written authorization from Xerxes will void the tank warranty. CAUTION Use of unapproved backfill material may cause tank failure, or damage the tank or surrounding property. 5.1.3. Approved backfill must meet the following specifications: 5.1.3.1. The material is washed, free-flowing, and free of ice, snow and debris. 5.1.3.2. The material conforms to the specifications of ASTM C-33, par. 9.1, size numbers 6 through 8 of Table 2. 5.1.3.3. When using pea gravel, the material is to be a mix of rounded particles, sizes between 1/8 inch and 3/4 inch. (See FIGURES -1.) FIGURE 5-1 5.1.3.4. When using crushed stone, the material is to be a mix of angular partides, sizes between 1/8 inch and 1/2 inch. (See FIGURE 5-2.) FIGURE 5-2 5.1.3.5. No more than 5% (by weight) of the material may pass through a #8 sieve. 5.1.3.6. It is recommended that the materials supplier certifies that the material conforms to ASTM C-33 and any other applicable specifications. 5.1.4. For additional information, refer to the Xerxes document, Fiberglass Tank Backfill Guidelines. 5.1.5. If material which meets these specifications is not available, contact technical support at Xerxes Minneapolis for information on alternate materials and the process for approval. 6. EXCAVATION PARAMETERS WARNING Follow OSHA regulations for tank excavations. Collapse of excavation walls could result in death or serious injury. 6.1. GENERAL 6.1.1. The installing contractor must take all precautions necessary to protect employees working in or near a tank excavation. These precautions should include, but are not limited to the following: 6.1.1.1. Locate and protect any utility installations near the excavation before opening the excavation. 6.1.1.2. Secure the walls of the excavation. 6.1.1.3. Prevent exposure of employees to hazardous fumes from the excavation. 6.1.1.4. Protect employees from hazards associated with water accumulation in the excavation. 6.1.1.5. Erect barricades, etc., to prevent unauthorized vehicle or pedestrian traffic. 6.1.1.6. Inspect, a minimum of once a day, the excavation and surrounding area. 6.1.2. For additional information on excavation, trenching and shoring safety practices, consult the following OSHA standards: Part 1926, Subpart M (Fall Protection), 500-503; and Part 1926, Subpart P (Excavations), 650-652. 6.1.3. The minimum depth of the excavation is normally determined by the presence or absence of groundwater and the presence or absence of traffic at the site. These dimensions are critical to the successful installation of a tank and are often regulated by code. 6.1.4. For additional requirements and specifications, refer to federal, state and local codes; and FIGURE 6-1 and FIGURE 6-2. 6 6.1.5. In all cases, the depths of cover given in 6.1.5.1. and in 6.1.5.2. are minimums. 6.1.5.1. Tanks subjected to traffic loads (H-20 loads) must have a cover depth of at least 36 inches of backfill [48 inches for 12 -foot -diameter tanks], or 18 inches of backfill [36 inches for 12 -foot -diameter tanks] plus 6 inches of reinforced concrete or 9 inches of asphalt. (See FIGURE 6-1.) In a wet condition, sufficient overburden and/or an appropriate anchoring system must be present to offset buoyancy of the tank. .1111111 0111111E1111 111E11111- - 11111.1111L Note: Number in brackets refers to 12 -toot -diameter tanks.

FIGURE 6-2 A WARNING In a nontraffic installation, ensure that the areas above the tanks are not subjected to traffic or other types of loads, which could cause tank damage and result in death or serious injury. 6.1.5.3. The maximum burial depth is 7 feet of cover over the top of the tank. Call your Xerxes representative for a. special quotation for a made-to-order tank if the burial depth is to be greater than 7 feet. 6.1.5.4. Asphalt and concrete pads must extend a minimum of 12 inches beyond the tank in all directions. 6.1.5.5. Iffthere is an unattached riser over an access opening, it must not transmit load from the asphalt or concrete slab to the tank. A minimum space of 6 inches must exist between the bottom of the riser and the top of the tank. 1 1 1 1 1 1 1 1 1 1 1 1 6.1.5.6. If there is an attached riser on an access opening, it must not transmit load from the asphalt or concrete slab to the tank. A minimum space of 3 inches must exist between the riser or sump and the slab. 6.2. TANK SPACING 6.2.1. GENERAL 6.2.1.1. The following are minimum spacings and must be increased as needed to accommodate deadmen or anchor slabs. (See Section 7.) 6.2.1.2. Always provide sufficient clearance to allow the deadmen to be set outside of the tank "shadow." (See FIGURE 6-3.)

UNSTABLE IN SITU SOIL CONDITIONS CAUTION Xerxes recommends that the tank owner seek the advice of a local foundation professional engineer if the in situ soil is extremely soft or inherently unstable (for example, peat, quicksand, muck, landfill, very soft or highly expansive clay, underground stream, etc.). 12.3.1. If the soil has Tess than 750 lbs./sq. ft. cohesion as calculated from an unconfined compression test; or in soils aving an ultimate bearing capacity of less than 3,500 lbs./sq. ft.; r where soil will not maintain a vertical wall, the excavation must 'low a minimum space equal to half the diameter of the tank between the excavation wall and both the side and the endcap of le tank, to enhance lateral resistance. (See FIGURE 6-5.) 7 6.2.3.2. The spacing between adjacent tanks is to be at least 18 inches. (See FIGURE 6-5.) 8ul" 1/2 -ink Da. 'ye �ll1lu/2 Tank Dia. 4#1011 —400V=1ILV1111=11E1011 M=�l-WU 1111II1_DIOL710111=0711-1110=01m FIGURE 6-5 6.2.3.3. A reinforced concrete slab may be required under the tank as a foundation in the excavation where the bottom is unstable. 6.3. GEOTEXTILE 6.3.1. The tank owner or the owner's technical representative is responsible for determining whether a geotextile or an alternate filtering technique is appropriate for a specific installation. Geotextile allows the passage of water, but prevents the migration and mixing of in situ soil and the select backfill material. Geotextile helps preserve the integrity of the select backfill envelope, which surrounds and supports the tank. 6.3.2. Xerxes recommends that geotextile be used when the tank is installed in: • areas with frequently changing groundwater conditions or areas subject to tidal fluctuations, - • unstable soils such as cited in SECTION 6.2.3, • water conditions with silty in situ soil. 6.3.3. For further information concerning geotextile specifica- tions and installation procedures, consult the geotextile supplier's installation guidelines or instructions. 6.3.4. Polyethylene film is not considered an effective geotextile material. It may tear or degrade while in service. 7. ANCHORING TANKS CAUTION Xerxes recommends that every site be thoroughly evaluated for the potential of a rise in the local water table or of trapped water. Failure to anchor a tank when required may cause tank failure, or damage the tank or surrounding property. 7.1. DEADMEN 7.1.1. Deadmen are typically a reinforced concrete beam. 7.1.2. The length of deadmen is typically equal to the length of the tank. 7.1.3. Deadmen maybe fabricated in multiple sections as long as the total length of each deadman is not decreased and as long as each section contains at least two balanced anchor points. 7.1.4. The width and thickness of deadmen depend on the tank diameter, water -table height, number of access openings that extend to the surface and burial depth. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 7.1.5. Deadmen should be designed according to the American Concrete Institute (ACI) code. 7.1.6. Refer to TABLE 7-1 for typical deadmen dimensions given the situation of an empty tank with a burial depth of 3 feet, with groundwater to grade and with two 24 -inch access openings that extend to the surface. Tank Diameter Typical Deadman Dimensions (Width x Depth) 4' 6"x6" 6' 12" x 12" 8' 12" x 12" 10' 18"x9" 12' 36"x8" TABLE 7-1 7.1.7. Tanks of 10 -foot diameter with a capacity of 30,000 gallons or larger may require larger deadmen than those in TABLE 7-1, depending on burial depth, to offset buoyancy. Contact technical • support at Xerxes Minneapolis for further information. 7.1.8. Lay the deadmen in the excavation parallel to the tank and outside of the tank "shadow." (See FIGURE 6-3.) 7.1.9. In multiple tank installations with deadmen: • each tank will have its own set of deadmen (one deadman may be used between two tanks if the deadman is double in width); • a separate anchor point must be provided for each hold-down strap; • the minimum spacing between tanks must be no less than twice the width of a single deadman. 7.2. XERXES PREFABRICATED DEADMEN 7.2.1. Xerxes -supplied prefabricated deadmen are pre- engineered and sized to the tank ordered. As with any deadmen, water -table height, number of access openings that extend to the surface and burial depth must be considered. 7.2.2. Placement of Xerxes prefabricated deadmen is the same as standard deadmen. (See FIGURE 7-1.) 7.2.3. Xerxes prefabricated deadmen are supplied with 3/4 -inch - diameter, galvanized, adjustable anchor points (subsequently referred to as anchor points). These anchor points protrude up through the slots in the aeadmen and are held in place with cotter pins. A WARNING Only use the anchor points when lifting and positioning the deadmen. A spreader bar may be required to lift longer sections of deadmen. Use guy ropes to guide the deadmen when lifting. Failure to do so could result in death or serious injury. 7.2.4. The anchor points can be moved and positioned to match hold-down strap locations on the tank (marked by arrowhead symbols —4). - 7.2.5. When using these deadmen in man -out -of -hole strapping 8 applications, align the anchor points with the proper ribs before setting them in the hole. (See SECTION 7.6.) 7.2.6. Care should be taken to keep backfill from entering the anchor point slot until final adjustment is made. 7.2.7. The deadmen are to be butted together at the tank center, on each side of the tank, when multiple sections are used. 7.2.8. Use one anchor point per strap end and only one strap per anchor point. 7.3. ANCHOR SLAB 7.3.1. An anchor slab is typically a reinforced .concrete base. 7.3.2. The total length of the slab must be at least the same as the length of the tank. 7.3.3. The minimum slab thickness is 8 inches. 7.3.4. The width of the slab depends on the tank diameter. The slab must extend a minimum of 18 inches [12 inches for 4 -foot - diameter tanks] beyond the width of the tank. 7.3.5. Refer to TABLE 7-2 and FIGURE 7-1 for anchor -point dimensions. 7.3.6. Provide a separate anchor point for each hold-down strap. 7.3.7, All anchor points must be engineered to withstand the tank's buoyancy forces. 7.3.8. When using a concrete base slab, allow sufficient depth in the excavation for 12 inches of bedding material below the tank. (See FIGURE 7-1.)

HOLD-DOWN STRAPS 7.4.1. Only Xerxes straps may be used when anchoring a Xerxes tank. 7.4.2. The locations for hold-down straps on each tank are marked on the tank by the arrowhead symbols 10-4 . 7.4.3. Straps must be used on all marked hold-down locations. CAUTION Do not place straps between ribs (except on 4 -foot -diameter tanks). Failure to properly place straps may result in tank damage. 7.4.4. Data for hold-down straps are given in TABLE 7-2 and FIGURE 7-1. 7.4.5. Evenly distribute loads by tightening all hold-down straps uniformly until they are snug over the ribs but cause no deflection of the tank. 7.4.6. Take a measurement of the internal diameter of the tank to determine whether vertical deflection is within the limits specified by Xerxes after the straps have been installed and tightened. (See SECTION 14 of the Installation Manual for instructions on taking diameter measurements.) 7.5. HARDWARE AND ANCHORING POINTS 7.5.1. Anchoring hardware must be sized according to TABLE 7-3, and manufactured to industry standards and dimensions. Tank Diameter Minimum Turnbuckle Diameter (by Type) Minimum Wire -Rope Diameter Hook I Jaw I Eye 4' 314" 1/2" 1/2' 3/8" 6' 3/4" 1/2" 1/2" 3/8" 8' 1-1/4" 3/4" 3/4" 1/2" 10' 1-1/4" 3/4" 3/4" 1/2" 12' 1-1/4" 3/4" 3/4" 1/2" TABLE 7-3 7.5.2. The installing contractor is responsible for providing hardware and anchor points of sufficient size and strength. 7.5.3. The particular configuration of hardware will be determined by the contractor, the owner or the owner's representative. 7.5.4. Locate the anchor points as shown in TABLE 7-2 and FIGURE 7-1. Refer to dimension "E." Align all anchor points with the marked arrowhead symbols N on the tanks, within a tolerance of ±1 inch. 7.5.5. For specific information on hardware and its use, consult the hardware manufacturer or supplier. 7.5.6. The installer is responsible for using appropriate and ap- proved engineering practices when fastening wire rope. Refer to recommendations of wire -rope manufacturer and supplier, and 9 follow accepted industry standards when selecting, using, attaching or connecting wire rope. (See FIGURE 7-3, FIGURE 7-4 and FIGURE 7-5.) A CAUTION Use only appropriately sized hardware with the strap eye. Oversized hardware may damage the strap eye and result in minor or moderate injury. See FIGURE 7-2 for dimensions of strap eye. FIGURE 7-2 7.5.7. When connecting the end of a hold-down strap to the anchor, common methods (shown in FIGURE 7-3) are: A.) using a drop -forged turnbuckle, B.) using a looped wire rope, or C.) using a combination of both. FIGURE 7-3 7.5.8. All exposed metal on the anchoring system must be coated or galvanized to protect against corrosion. 7.5.9. When fastening wire rope, use a minimum of two clips for a 3/8 -inch wire rope and three clips for a 1/2 -inch wire rope on each termination. See TABLE 7-3 for minimum wire -rope diameter. 7.5.10. Turn back from thimble the exact amount of wire rope specified by the manufacturer of the clips used. 7.5.11. Apply the first clip at a distance from the dead end of the wire rope that is equal to the largest width of the clip used. (See FIGURE 7-4.) 7.5.12. For each clip, apply a U -bolt over the dead end of wire rope. (See FIGURE 7-4.) (Note: Live end rests in saddle.) • s wwui r ::mwm1::: S •�� a��u��o�oma� Dead End FIGURE 7-4 7.5.13. When two clips are required, apply the second clip as near the loop or thimble as possible. (See FIGURE 7-4.) 7.5.14. When more than two clips are required, apply the second clip as near the loop or thimble as possible; turn nuts on second clip firmly, but do not tighten initially. (See FIGURE 7-4.) 7.5.15. When more than two clips are required, space additional clips equally between the first two; take up rope slack; and tighten nuts on each U -bolt evenly. 7.5.16. Tighten all hardware uniformly and follow the manufac- turer's torque specifications. Double-check the tightness once the anchoring system is complete. 7.5.17. If forming a loop in the wire rope, a splice is required for connecting the two ends together. Standard rigging practice for splicing wire rope calls for using twice the number of clips recommended for a single -end termination. Use a minimum of four clips for a 3/8 -inch wire rope and a minimum of six clips for a 112 -inch wire rope. Place the rope ends parallel to each other and install the clips as shown in FIGURE 7-5. 3/8" Wire Rope — Live End —) —peed End -0.-E [—Load Load -0 - Dead End 0k Live End —I 1/2" Wire Rope Live End YIF Dead End Dead End • Live End —0 - FIGURE 7-5 7.6. MAN -OUT -OF -HOLE ANCHORING 7.6.1. The Xerxes man -out -of -hole (MOH) strapping system is designed for use in installations where water is in the excavation and/or where personnel may not enter the hole because of site restraints. An MOH strapping system can be, but need not be, used in conjunction with Xerxes deadmen. 7.6.2. When using the MOH strapping system, the placement of components is critical. (See FIGURE 7-6.) See separate Xerxes document, Man -Out -of -Hole (MOH) Installation Instructions.

ALTERNATE ANCHORING METHODS IN WET -HOLE INSTALLATIONS 7.7.1. In wet -hole installations, when Xerxes' preferred method of man -out -of -hole anchoring is not available, the following methods may be used. 10 7.7.1.1. With both methods, place the hold-down strap between the wire rope and the tank so that the wire rope is never in direct contact with the tank. 7.7.1.2. The H-shaped positioning clips around the strap are designed to accommodate the wire rope on top of the strap as shown in FIGURE 7-7 and FIGURE 7-8. 7.7.1.3. The following method is shown in FIGURE 7-7: • attach a wire rope to each end of each hold-down strap; secure the termination of the wire rope (See SECTION 7.5. for suggested method.); center each hold-down strap on each rib marked with the arrowhead symbols -4 ; place the deadmen on top of the wire ropes on each side of the tank; lower the deadmen to the bottom of the excavation; take the slack out of each wire rope and splice the termination of the wire ropes on top of the tank (See SECTION 7.5.). FIGURE 7-7 7.7.1.4. The following method is shown in FIGURE 7-8: • loop a wire rope around the deadman at each location that cor- responds to each rib marked with the arrowhead symbols -4 ; • secure the termination of the wire rope (See SECTION 7.5. for suggested method.); • lower each deadman to the bottom of the excavation using the wire rope; - • center each hold-down strap on each rib marked with the arrowhead symbols 10 ; • bring the live end of each wire rope up to the top of the tank at each marked rib; • take the slack out of each wire rope and splice the termina- tion of the wire ropes on top of the tank (See SECTION 7.5.). FIGURE 7-8 S. BOTTOM FITTINGS 8.1. GENERAL 8.1.1. When handling a tank with a bottom sump or fitting, always take extra care so that the bottom sump or fitting is not damaged. 1 1 1 1 1 1 1 CAUTION All connections to the tank must be flexible. Provisions must be made to accommodate movement and misalign- ment between the piping and the tank. Failure to do this may damage the tank or surrounding property. 8.1.2. During installation, provide a clear area in the backfill bedding so that the tank rests on the backfill bedding and the bottom fitting is clear. 8.1.3. After setting the tank, fill and tamp the resulting void by using hand tools before continuing the backfilling. 9. INSTALLATION A WARNING Do not use air pressure to test tanks that contain or have contained flammable or combustible liquids or vapors. The fuel and air mixture could explode and result in death or serious injury. Tanks should be air tested before ballasting. CAUTION Adequately ballast the tank (add liquid) in a wet hole or in a dry hole that may become wet (for example, from site runoff) until the installation has been completed. Failure to do this may damage the tank or surrounding property. P. 9.1. GENERAL 9.1.1. Use only approved backfin material. (See SECTION 5.) I 9.1.2. Do not mix approved material with sand or in situ soil. 9.1.3. Do not use in situ soil as backfill material. ll 9.1.4. All excavated in situ soil must be replaced with approved material. 9.2. DRY -HOLE INSTALLATION 9.2.1. Prepare a smooth level bed, 12 inches thick, of approved II backfill material. 9.2.2. Refer to SECTION 2.1.3. regardingthe use of lifting lugs 'to hoist the tank when unloading and installing it. 9.2.3. Place the tank or tanks onto the bed. Do not set Xerxes Utanks directly onto a concrete slab, on timbers or cradles, or onto the in situ soil. 9.2.4. As the tank is being placed, slope the tank according to site Ilspecifications. (Xerxes does not require that a tank be sloped. The slope is determined by the tank owners specifications.) 9.2.5. Sloping of tanks may affect accuracy of Xerxes calibration 'charts. 9.2.6. Use the tops of the ribs to establish longitudinal level. stablish lateral level by placing the level across the top of a fitting or a manway. 9.2.7. When the tank is placed, take a measurement of the iternal diameter of the tank. (See SECTION 14 of the 11' Installation Manual for instructions on taking diameter measurements.) Record this measurement as Initial Internal Diameter on the Tank Installation Checklist, Section 4. 9.2.8. If tank is to be anchored, install the anchoring hardware at this time. (See SECTION 7.) 9.2,9. Place one 12 -inch lift of approved backfill material evenly around the tank. From the edge of the hole or the top of an adjacent tank, push the backfill in place by using a nonmetal probe long enough to reach beneath the tank. Work the backfill material under the tank body and domes so the tank is fully supported — that is, so there are no voids under the tank. (See FIGURE 9-1 and FIGURE 9-2.) ® CAUTION Do not strike the tank with the probe or tank damage may result. FIGURE 9-1 FIGURE 9-2 9.2.10. Repeat Step 9.2.9. with a second 12 -inch lift. 9.2.11. After the second lift of material has been placed and worked under the tank, bring the backfill to the top of the tank. 9.3. WET -HOLE INSTALLATION 9.3.1. Follow the dry -hole installation procedure (SECTION 9.2.) with the following modifications: 9.3.1.1. Before performing Step 9.2.1. of the dry -hole installa- tion, take a measurement of the internal diameter of the tank before the tank is placed in the excavation hole (See SECTION 14 of the Installation Manual for instructions on taking diameter measurements.) Record this measurement as Initial Internal Diameter on the Tank Installation Checklist, Section 4. 9.3.1.2. Before performing Point 9.2.1. of the dry -hole installation, pump the water from the hole and continue pumping to maintain minimum water level during tank installation. 9.3.1.3. During Step 9.2.3. of the dry -hole installation, when setting and leveling the tank, partially ballast the tank until it settles firmly on the prepared bed. The ballast level in the tank must never exceed the water level in the hole by more than 1 foot until the backfill reaches the top of the tank. (See FIGURE 9-3.) 9.3.1.4. Omit Point 9.2.7. VIII :at: at fa modr.walt tdottalatt 1111 1111 FIGURE 9-3 9.3.2. Cover depth must meet minimum depth as specified in SECTION 6 of this Installation Manual. 9.3.3. Completely ballast the tank once backfill is even with the top of the tank. 10. OPTIONAL POSTINSTALLATION TESTING 10.1. GENERAL 10.1.1. Verify that the vertical deflection is within tolerances listed in the table on the Tank installation Checklist, Section 4. 10.2. OPTIONAL HYDROSTATIC TEST 10.2.1. Seal off influent and effluent piping with watertight caps or plugs. 10.2.2. After the hole is backfilled to the bottom of the influent/effluent piping, fill the tank with water up to 3 inches into the access openings. 10.2.3. Let the water stand in the tank for a minimum of 1 hour (or longer if required by applicable local codes). 10.2.4. If the water level drops, check to see that plugs or caps sealing off piping are tight and then add more water to fill air voids back to the standard testing level. (See Step 10.2.2.) 10.2.5. If water level does not stabilize, there may be a leak in the system. If damage is detected, do not attempt repairs. Contact the LIST coordinator at the Xerxes plant nearest you. Telephone and fax numbers are found on the back cover of this manual. 11. BALLASTING (ADDING LIQUID) 4 WARNING The tank shall be adequately vented to prevent the development of vacuum or pressure when filling or emptying the tank. Failure to properly vent the tank/compartments could cause tank failure and result in death or serious injury. 11.1. GENERAL 11.1.1. In most anchoring systems, a tank is not adequately protected against flotation until the tank is fully backfilled to final grade (or until the top slab is in place if applicable). Therefore, during the installation process, the tank should be ballasted completely after the backfill is even with the -top of the tank and postinstallafion testing has been successfully completed. 11.1.2. Only under wet -hole conditions should ballast be added 12 before the backfill is even with the top of the tank. (See SECTION 9.) 12. PIPING AND VENTING 12.1. INTERNAL PIPING 12.1.1. All piping must conform to all applicable codes and standards. (See SECTION 1.) CAUTION All internal piping must be at least 4 inches j6 inches for 12 -foot -diameter tanks] from the tank bottom. Failure to do this may damage the tank or surrounding property. CAUTION All metal fittings and other metal components must be coated to protect against corrosion. Failure to do this may result in damage to these parts or to surrounding property. 12.1.2. Refer to FIGURE 12-1 along with TABLE 12-1 to determine the correct dimensions for sizing internal piping. _j7" 'A' is the internal diameter of the tank. "B` is the distance between the inside bottom of the tank and the internal flange of the access riser. 'C" is the distance between the inside bottom of the tank and the top of the access opening. FIGURE 12-1 Interior Dimensions in FIGURE 12-1 Tank Diameter 4' 6' 8' 10' 12' 48" 71-3/8" 91" 119-1/4" 138-1/2" 51-3/8" 74-3/4" 94-3/8" 122-5/8" 142" 55-318" 78-3/4" 98-3/8" 126-5/8" 146" TABLE 12-1 12.2. EXTERNAL PiPING A WARNING if pressure testing the external piping, the tank must be isolated from all piping. The test pressures for external piping could cause tank failure, and result in death or serious injury. CAUTION All connections to the tank must be flexible. Provisions must be made to accommodate movement and misalign- ment between the piping and the tank. Failure to do this may damage the tank or surrounding property. 12.2.1. All connections to the influent and effluent piping as well as to any other piping must be flexible and properly sized. 1 1 1 1 1 1 1 1 12.3. VENTING TANK ® WARNING ,411 underground tanks/compartments shall be adequately vented to prevent the development of vacuum or pressure when filling or emptying the tank. Failure to properly vent a tank or compartment could cause tank failure and result in death or serious injury. 12.3.1. The single-wall tank is designed to operate at atmospheric pressure. 12.3.2. The tank's venting system must be adequately sized to ensure that atmospheric pressure is maintained at all times, including during filling and emptying of tank. 13. BACKFILLING TO GRADE 13.1. GENERAL 13.1.1. Continue to take safety measures (such as placing barricades) around the excavation site until installation is completed. 13.1.2. When the tank has been set, tested and backfilled, and all piping and venting has been completed, add the balance of the backfill material. 13.1.3. The backfill must be free of debris, ice or snow. Any blocks or bricks used as support material during piping must be removed prior to completion of backfilling. lik13.1.4. The backfill material specified in SECTION 5 must be used to completely fill excavation. '13.1.5. Be sure that the installation meets all of the require- ments of minimum cover as specified in SECTION 6. I13.1.6. When the tank has been backfilled to subgrade (before placement of asphalt or concrete), take a measurement of the internal diameter of the tank. (See SECTION 14 of the Installation Manual for instructions on taking diameter Imeasurements.) Record this measurement as Final Internal Diameter on the Tank Installation Checklist, Section 4. 13.1.7. Complete the Tank Installation Checklist. 14. DEFLECTION MEASUREMENTS 114.1. GENERAL 14.1.1. Obtain the deflection measurement by taking a minimum of two measurements of the internal diameter of the tank. 114.1.2. Two methods of measuring the internal diameter of the tank are described here. Both methods use a dipstick. (Similar methods can be used, such as with a tape.measure, etc.) 14.1.3. The deflection measurement can be obtained by using either method twice or by using each method once. Each will be escribed here as if that method were being used twice. 4.1.4. Take the initial intemal-diametermeasurement before backfilling the tank. (See Step 9.2.7.) In a wet -hole installation, Ike this measurement before the tank is placed in the 13, excavation hole. (See Step 9.3.1.1.) 14.1.5. Take other diameter measurements during the backfilling process to determine whether vertical deflection continues to be within the limits specified by Xerxes. (See Steps 7.4.6 and 10.1.1.) 14.1.6. Take the final internal -diameter measurement when the tank has been backfilled to subgrade. (See Step 13.1.6.) 14.1.7. For both methods, drive a small -headed, nonsparking nail (for example, brass) halfway into a wooden dipstick 1 inch above its base. 14.2. INTERNAL -DIAMETER MEASUREMENT WITHOUT A STANDPIPE 14.2.1. Place the dipstick into a service fitting. 14.2.2. Measure and record the distance from the tank bottom to the top of the fitting. 14.2.3. Pull the dipstick up until the exposed nail catches on the inside top of the tank. 142.4. Measure the distance from the tank top (inside) to the top of the fitting. Subtract 1 inch from this measurement and record the distance. 14.2.5. Subtract the second distance (inside tank top to top of fitting) from the first distance (tank bottom to top of fitting). Record this measurement as Initial Internal Diameter on the Tank Installation Checklist, Section 4. 14.2.6. For subsequent measurements of the intemal diameter, repeat Steps 14.2.1. through 14.2.5. When the measurement is the final diameter measurement, record this measurement as Final Internal Diameter on the Tank Installation Checklist, Section 4. 14.3. INTERNAL DIAMETER MEASUREMENT WITH A STANDPIPE 14.3.1. Place the dipstick into a service fitting with a standpipe. 14.3.2. Measure and record the distance from the tank bottom to the top of the standpipe. 14.3.3. Put the dipstick up until the nail catches on the inside top of the tank. 14.3.4. Measure the distance from the tank top (inside) to the top of the standpipe. Subtract 1 inch from this measurement and record the distance. 14.3.5. Subtract the second distance (inside tank top to top of standpipe) from the first distance (tankbottom to top of standpipe). Record this measurement as Initial internal Diameter on the Tank Installation Checklist, Section 4. 14.3.6. For subsequent measurements of the internal diameter, repeat Steps 14.3.1. through 14.3.5. When the measurement is the final diameter measurement, record this measurement as Final Internal Diameter on the Tank Installation Checklist, Section 4. 14.4. CALCULATION AND COMPARISON 14.4.1. To get the deflection measurement at any time, subtract the current internal diameter measurement from the initial internal -diameter measurement. 14.4.2. Compare this measurement to the allowable deflections shown in the table on the Tank Installation Checklist, Section 4. 14.4.3. Vertical deflection in excess of this measurement indicates improper installation and voids the tank warranty. 15. ADDING TAN AT EXISTING LOCATION 15.1. GENERAL 15.1.1. Additional Xerxes tanks may be installed at existing locations if proper foundation support exists. 15.1.2. It is the responsibility of the tank owner to choose the correct method of installation. 15.1.3. Xerxes requires that one of the following methods be used. 15.2. PREFERRED METHOD 15.2.1. The preferred method (FIGURE 15-1) is: • Install a new tank in a separate hole at least 3 feet from the original hole. Follow procedures outlined in this Installation Manual. Exercise caution in keeping unusual surface loads off existing tanks. Maintain the natural barrier of undisturbed soil between tanks. 36" oetaYibmiraflei ss_ ilild��ifl'I��Flltl�d��tl FIGURE 15-1 15-1 15.3. ALTERNATE METHOD 15.3.1. If the preferred method outlined above is not practical, an alternate method (FIGURE 15-2) is: • Bury additional tanks in the same installation hole. • Empty existing tanks tc less than 1/4 capacity. • Remove the surface slab. • Enlarge the excavation for the new tanks, leaving as much backfill as possible around existing tanks. • Install shoring, if necessary, to make sure that existing tanks do not move and sufficient backfill remains. • Follow procedures and requirements outlined in this Installation Manual. • See SECTION 6 for excavation parameters. 111 IIIIII III ' daunt T 1r1�'i'ri'=lfa—ltd— "I 7:t4M a --I N9=7,—IIIIo—K3dl:i.

The actual working capacity is determined by the elevation of the effluent piping/floats. Actual height of the tank may be greater than actual tank diameter due to fittings and accessories. Load height during shipping may vary due to tank placement on shipping trailer. Adding accessories to the tank may increase the tank weight. The Xerxes septic tank that can be pressure tested is not available in 12 -foot -diameter sizes. 7901 XERXES AVENUE SOUTH, MINNEAPOLIS, MINNESOTA 55431 • PHONE (952) 887-1890 • www.xerxescorp.com 16 WIMC01/03PP XERXES® CORPORATION Corporate Office Minneapolis, MN • Corporate Office 7901 Xerxes Avenue South Minneapolis, MN 55431 Phone: (952) 887-1890 Fax: (952) 887-1870 http://www.xerxescorp.com Manufacturing Facilities Anaheim, California Phone: (714) 630-0012 Fax: (714) 632-7133 Hagerstown, Maryland Phone: (301) 223-6933 Fax: (301) 223-6836 Seguin, Texas Phone: (830) 372-0090 Fax: (830) 372-0321 Tipton, Iowa Phone: (563) 886-6172 Fax: (563) 886-2042 West Memphis, Arkansas Phone: (870) 735-5353 Fax: (870) 733-1946 ©2003 Xerxes Corporation WIM01/03PP • 9 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ACRAI=.7 VVr r ovum 11VPI Dipstick Calibration Chart 1,500 Gallon -
