The staging areallaydown yard will be utilized to temporarily park drilling and completioniworkover rigs and associated equipment. Currently, when a rig completes a new producing well, it has to exit the area completely if another well site is not ready for occupation by the rig. This practice results in added traffic on the roadways as well as additional mobilization cost associated with the transportation in and out of the general area. The staging area would accommodate the rigs and equipment within a secure area on a short term basis. The types of equipment associated with the rig itself may include steel reserve pits, mud pumps, generators; diesel engines drill collars and pipe racks. Generally, all of this associated equipment is skid mounted and portable. 11 is anticipated that no more than two rigs will be parked within the facility at any given time. The duration for staging a particular rig and equipment within the facility is expected not to exceed 30 days. While in the staging area, the equipment could then receive the proper inspections and required maintenance resulting in a possible reduction in safety hazards and potential accidents as well as a general increase in performance and productivity. The site will be unmanned with the exception of periods when rig equipment is being moved in or out; or, during periods of maintenance and inspection. During rig moves, 4 to 5 heavy haul trucks will be used. The required permits will be obtained as required from the Garfield County Road & Bridge Department. EnCana anticipates that each truck will make one round trip during a one day period. The total moves during a year should average approximately one per month. Pickup and small service trucks will access the site only as required with the average roundtrips expected not to exceed 3 per week. EnCana plans to access the site from the north via an existing road which crosses Williams Production and EnCana property. Arrangements have been made with Williams for the use of their portion of the road. The existing access road was a part of the original Unocal easement. The anticipated duration of construction of the site is approximately 3 weeks. Construction procedures would include the grading and stockpiling of available topsoil and compaction of the surface material to a satisfactory level. Rock, road base, and gravel would be installed over the compacted area to insure durability and easy maintenance. Periodic watering and resurfacing may be required to prevent fugitive dust emissions. Storm water controls in the form of drainages and retention pond will be implemented to insure erosion controL • • • The design of the site will incorporate the installation of electrical power for lighting and security. All lighting will be used on an as needed basis only and will be directed so as not to adversely impact adjacent properties or traffic along County Road 215. Power outlets will also be installed in the appropriate locations to provide a location for plugging in vehicles and equipment during cold weather periods. No other above ground structures or appurtenances are planned for this site. TRAFFIC IMPACTS Staaine Area The overall impact in traffic volumes will be significantly reduced on all major roads in the surrounding area. Rigs and equipment will be stored at the staging site rather than being released from the operations and then being brought back in when needed. It is anticipated that rig traffic traveling to and from well sites may be reduced by as much as 50 percent over time. Mobilization cost will be substantially less both for EnCana and the contract company. • mmw 73 0 mom 0, iZ3 imam 'm coo - a mmom= imin m— m esz moo 7,- IMMO t=) 11IMME woo o --4w— oaf commi -nom, c n err/ 411 De1iware The First State PACE I, HARRIET SMITH WINDSOR, SECRETARY OF STATE OF TSE STATE OF DELAWARE, DO ABY CERTIFY TEE CERTIFICATE OF MERGER, jETCE MERGES: „TBI PIPELINE COMPANY", A DELAWARE CORPORATION, "TBI WEST VIRGINIA, INC.", A DELAWARE CORPORATION, "TOM BROWN, INC.", A DELAWARE CORPORATION, WI TIi AND INTO "ENCANA OIL & GAS (USA) INC _ " UNDER THE NAME OF "ENCANA OIL & GAS (USA) INC_ ", A CORPORATION ORGANIZED AND EXISTING UNDER THE LAWS OF TIE STATE OF DELAWARE, WAS RECEIVED AND FILED IN THIS OFFICF THE TWEENTY-SECOND DAY OF DECEMBER, A.D. 2004, AT 6:15 O'CLOCK P_M.

Sloping Weathered Rock Excavation: Excavation of soilfweathered rock that can typically be excavated with the rock auger, except the steeply sloping orientation of the stratum causes the rock auger to run askew. C. Rock Excavation: 1. Excavation of material that meets the rock auger refusal criteria and requires the rock core barrel or other hard rock excavation techniques for removal. 2. Rock auger refusal is defined as a penetration rate of less than 6 inches in 15 minutes, while operating a caisson drilling rig, rated with a torque capacity of at least one million inch -pounds, applying a continuous down pressure of at least 50,000 pounds, equipped with a rockauger that contains conical carbide -tipped ("Kennemetal") teeth. D. Nominal Soil or Weathered Rock Seams Nominal soil or weathered rock seams below rock auger refusal will be excavated and considered as rock for rock excavation quantities. A nominal soil or weathered rock seam is one which is less than 2 feet thick. Where soil or weathered rock seams or voids of 2 feet or greater are excavated within a mixed rock/soil or rock/weathered rock profile, excavation is classified as soil/weathered rock excavation until rock auger refusal is again established. 1.8 MEASUREMENT AND PAYMENT FOR ROCK EXCAVATION A. Measurement: Excavation type in units of length shall be considered to change at the upper contact with a different excavation type as defined by Section 1.7. B. Payment: Contract unit rates per length of each diameter caisson shall be provided for each excavation condition type noted above in Section 1.7. Contract price and time will be adjusted for overruns or underruns. C Payment for Differing Site Conditions: No payment will be made for any rock excavation beyond caisson limits.

The project site is shown on Figure 1. The purpose of the study was to develop recommendations for foundation design. The study was conducted in accordance with our proposal for geotechnical engineering services to Wagon Wheel Consulting, inc., dated February 20, 2006. A field exploration program consisting of exploratory borings was conducted to obtain information on the subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to determine their classification, compressibility or swell and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed to develop recommendations for foundation types, depths and allowable pressures for the proposed building-oundation. This report summarizes the data obtained during this study and presents our conclusions, recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions encountered. PROPOSED CONSTRUCTION The proposed warehouse and training facility will be a one and two story uietal biuilding with a slab -on -grade floor. A slab foundation with rigid foam insulation for frost protection is proposed for support of the structure. There will be an outside storage area. to the west of the warehouse that will also be a reinforced slab -on -grade, We understand that grading for the structure and exterior slab will involve cuts up to about 15 feet to level the site. We assume relatively light to moderate foundation and floor slab loadings, typical of the proposed type of construction. If -building loadings, location or grading plans change significantly from those described above, we should be notified to re-evaluate the recommendations contained in this report. Job No, 106 0149 RPR -04-20 16:37 H -P GEOTECH -2- SITE CONDITIONS The site was vacant at the time of our field exploration. The ground surface in the building area is relatively flat with a moderate slope down to the west at a grade of about 8%. There is about 10 to 12 feet of elevation difference across the building area. Existing detention ponds arc located to the south aid southwest of the pro -posed building area. Vegetation consists of grass and weeds. FIELD EXPLORATION The field exploration for the project was conducted on March 6, 2006. Four exploratory borings were drilled at the locations shown on Figure 1 to evaluate the subsurface conditions. The borings were advanced with 4 inch diameter continuous flight auger powered by a truck -mounted CME -45B drill rig. The borings were logged by a representative of Hepworth.-Pawlak Geotechnical, Inc. Sas;iples of the subsoils were taken with a 2 inch I.D. spoon sampler. The sampler was driven into the subsoils at various depths with blows from a 140 pound hammer falling 30 inches. This test is similar to the standard penetration test desaibcd by ASTM Method D-1586. The penetration resistance values are an indication of the relative 4ensity or consistency of the subsoils. Depths at which the sarnples were taken and the penetration resistance values arc shown on the Logs of Exploratory Borings, Figure 2_ The samples were returned to our laboratory for review by the project engineer and testiryg. SUBSURFACE CONDITIONS Graphic logs of the subsurface profiles encountered at the site are shown On Figure 2. Below about 1 foot of organic topsoil, the subsoils consist of stiff to hard. sandy silty clay vial, scattered gravel to the drilled depths of 3 I feet. Laboratory testing performed on samples obtained during the field explorarion included natural moisture content, density and finer than sand size gradation analysis, Swell - Job 'N'"o well• Job'o 106 0199 sgEst APR -04-2006 16=37 H -P GEl.1TECH -3- consolidation testing was pe,rfonned on relatively undisturbed drive samples of the clay subsoils. The swell -consolidation test results, presented on Figures 4 through 7, indicate low compressibility under relatively light surcharge loadi> a and typically expansion potential when wetted under a constant light surcharge. Two of the sarnplee showed a low collapse potential (settlement under constant load) when wetted and moderate to high compressibility under additional loading. The swelling pressures of the expansive samples were between about 1,200 psf and 14,E psf. The laboratory testing is summarized in Table I. Groundwater was measured in Borings 2 and 3 at depths of 29 and 29V2 feet, respectively. The upper soils were generally slightly moist to moist FOUNDATION BEARING CONDITIONS The subsoils materials encountered at the site possess variable scttiemefltAleave potential when wetted_ The expansion potential can be partly mitigated by load concentration on isel;ted footings to reduce or prevent swelling in the event of wetting below the fonndation bearing level. Surface runoff, landscape irrigation, and utility leakage are possible sources of water which could cause wetting. Load concentration to mitigate expansive soils will not be practical for the proposed slab foundation and some differential heave should be expected. DESIGN RECOMNEENOATIONS SLAB FOUNDATION Considering the subsurface conditions encountered in the exploratory borings and the nature of the proposed construction, the building can be founded with a slab foundation placed on the natural clay soils or compacted structural fill with a risk of slab heave and distress. • Job N(.1106of99 G • APR -04-2006 16:37 H -P GEUIECH -4- r.iv The slab foundation should have adequate section and reinforcement to sup ,ort the building loads and to resist potential center or edge upliftfrom heave of the clay bearing soils. The slab can be either conventionally reinforced or post -tensioned to resist movement, depending on the design method or construction procedures selected. When the design method has been selected, we should review the soil procedures ler appropriate velar s. The IJBC method for conventionally reinforced mats (Section 18.5) requires soils design parameters of unconfined compressive strength and plasticity index. The unconfined compressive strength can be assumed as 6,000 psf and the plasticity index as 20 for the natural clay soils at the site. The perimeter edge of the slab should be turned down as needed to provide frost cover of 36 inches or protected from frost penetration by rigid foam insulation. The excavation should be cut to the design hearing level, removing all topsoil and loose disturbed soils. The exposed subgrade should be evaluated for ea;ttanston potential at the time of construction. The differential heave potential can be reduced by providing at least 3 feet of compacted, granular structural fill below the slab foundation. The structural fill should consist of a nt nexpansive material approved by the geotechnical engineer. The ill should be compacted to at least 98% of the maximum standard Proctor density (ASTIv 1)698) ata m 'i.sture content near optimum. The fill should extend laterally beyond the edge of the slab at least 3 feet. Prior to fill placement the subgrade should be carefully prepared by removing all topsoil, scarifying to a depth of 8 inches, adjusting the motstt -e content slightly above optimum and compacting to 95% of standard Proctor density. For ease of construction, we suggest road base material be used as the structural fill. An open graded material, such as crushed rock, which could allow water into the subsoils, should not be used as the fill. FLOOR SLABS The on-site soils possess an expansion potential and slap heave could occur ifihc subgrade soils were to become wet. The slab foundation should help to limit distress in the event of slab heave. Slab -on -grade construction may he used provided precautions are taken to limit potential rnovennent and the risk of distress to the building is accepted Job ;o. If%%0199 iGgritecil APR -04-2006 16:37 H -P GEOTE+CH - r . EA3' J. by the owner. A positive way to reduce the risk of slab znovantem, which is commonly use in the area, is to construct structurally supported floors over crawlspace. A cart wispace would require the use of a different building foundation system such as footings designed for the heave potential or driven piles or piers. To reduce the effects of some differential movement, nonstructural tloo.r slabs should be separated from all hearing walls and columns with expansion joints which allow unrestrained vertical movement. Interior non -hearing partitions testing on floor slabs should be provided with a slip joint at the bottom of the wall so that, if the slab moves, Clic movement cannot he transmitted to the upper structure. This detail is also important for wallboards, stairways and door frames. Slip joints which will allow at least 1'/2 inches of vertical movement are recommended. Floor slab control joints should be used to rediicc damage due to shrinkage cracking- Slab reinforcement and control joints should be Lstablished by the desigter based on experience and the intended slab ase. Required fill beneath slabs should consist of a suitable imported granular material, excluding topsoil and oversized rocks. The fill should be spread in thin liorizontrallifts, adjusted to at or above optimum moisture content, and compacted to at least 95% of the maximum standard Proctor density. All vegetation, topsoil and loose or disturbed soil should he removed prior to fill placement. The above recommendations will not prevent slab heave if the expansive soils underlying stabs -on -grade become wet. However, the recommendations will reduce the effects if slab heave occurs. All plumbing lines should be pressure tested before backfilling to help reduce the potential for wetting. SURFACE DRAINAGE The following drainage precautions should he observed during construction and maintained at all times after the building has been completed' ,i) No t 060149 c - 5vect-• 4'R-64-2006 16:38 H -P GEOTECH r. U7, lv 1) Excessive wetting or drying of the foundation excavations and underslab areas should he avoided during construction. Drying could increase the expansion potential of the clay soils. 2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95% of the maximum standard Proctor density (ASTM D698) in pavement areas and to at lest 90% of the maximum standard Proctor density in landscape areas. 3) The ground surface surrounding the exterior of the building should be sloped to drain away from the foundation in all directions. We . recommend a minimum slope of 6 inches in the first 10 feet it unpaved areas and a minimum slope of 3 inches iii the first 10 feet in paved areas. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Irrigation sprinkler heads and landscaping which requires regular heavy irrigation, such as sod, should he located at least 5 feet from fciundation walls. LIMITATIONS This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no warranty either express or implied. The conclusions and recommendations submitted in this report are based upon the data obtained from the exploratory borings drilled at the locations indicated on Figure 1, the proposed type of construction and our experience in the area. Our services do riot include determining the presence, prevention or possibility of mold or (Alia biological contaminants (MOBC) developing in the future. if the char .is concerned about MOBC, then a professional in this special field of practice should be consulted. Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory borings and variations in the subsurface conditions may not become evident until excavation is performed. f f conditions encountered during construction appear to he different from those described ui this report, we should be notified at once so re-evaluation of the recommendations may be made. • 1,71) --No. 10611399 Gatedo APR -04-2006 16:38 H—P GEOTECH _7_ This report has been prepared for the exclusive use by our client for design purposes.

CONTROLS - GENERAL BEST MANAGEMENT PRACTICES The following is a list of common Best Management Practices (BMP) which Encana employs during construction activities. Erosion control implementation will be conducted under the guidance of persons experienced in construction techniques. Local factors will be evaluated to determine what BMPs are suitable and practical for each construction project. a. Erosion Control 1. The size of the construction area will be minimized to the extent practical to prevent unnecessary disturbance of local soils. 2. Significant grade changes will be minimized when practical. 3 Water diversion structures will be constructed if deemed appropriate. These structures include water bars, drainage dips, culverts and wing Encana Oil & Gas (USA) Inc. Orchard Corepressor Station Storm Water Management Plan ditches. 4. Roads and well pads will be stabilized as soon as practical after construction. b. Road Construction 1, Existing roads will be used whenever possible. 2. Typically, roads will follow ridge lines to minimize road grades whenever possible, in accordance with the land owner agreement. 3. Stream crossings are avoided when possible. Existing crossings or bridges will be used. 4. Vehicles are confined to authorized traffic routes. c. Well Pads 1. Slopes are minimized to lessen erosion rates. 2. Wetlands, shallow ground water and flood plains are avoided whenever possible. 3. Fuels that are stored on-site are diked to prevent potential run-off in the event of a spill. 4. Trenches are dug around the various rigs to collect spills and wash water, 5. Absorbents, drop liners and catch pans are used to collect spills and drips. d. Spacing for Erosion Control 1. Waterbar and drainage dip spacing on the location will be as follows: % SLOPE 2 OR LESS 2TO4 4 TO 5 5 OR MORE SPACING INTERVAL 200 FEET 100 FEET 75 FEET 50 FEET e. Re -seeding 1. All disturbed areas will be re -seeded as recommended by the Surface Management Agency or the Soil Conservation Service. Seed will be planted using a drill, and in areas not suitable for drilling, the seed will be Encana Oil & Gas (USA) Inc, Orchard Compressor Station Storm Water Management Plan broadcasted and raked, or chained to cover the seed. Re -seeding will begin as soon as practical. TYPICAL SEED MIXTURE ( Agency Formula) SPECIES TBD LBS/ACRE TBD f. Stormwater Management 1. To prevent or control potential erosion, water bars, drainage dips and wing ditches are cut across ROW's. These structures divert the water runoff from the disturbed areas into the vegetated areas, dissipate the velocity and reduce the sediment loading. g. Other Controls 1. All equipment and vehicular access is confined to existing roads and the established right of way corridor. 2. No construction or routine maintenance activities will be done during periods when the soil is too wet to adequately support construction equipment. If such equipment creates surface ruts in excess of 12 inches deep, it will be deemed that the soil conditions are too wet to adequately support construction equipment. Construction activities will not continue until soil conditions improve. 3, Construction sites shall be maintained in sanitary conditions at all times; waste materials at these sites shall be disposed of promptly and at appropriate waste disposal sites. 4. A contractor will be used to provide and maintain portable toilets. 1 1 . MAINTENANCE The new construction areas will be routinely patrolled and inspected by vehicle to check for problems such as; erosion, right of way condition, unauthorized encroachment on the right of way and any other situations that could cause a safety or environmental hazard, or require preventive maintenance on these areas.

This manual provides design criteria for a variety of techniue to address these issues. These techniques, or BMPs, consist of both temporary andpermanent to reduce pollution from a construction site. The majority of BMPs address onsite soil losses. For construction sites, soil loss. In the form of erosion and sedimentation as results of storm events and wind, constitutes the majority of pollution generated from a construction site. BMPs which address erosion and sediment control are much more site specific than waste management techniques. Erosion and sediment control BMPs are dependent upon site slopes, drainage patterns and quantities, and other site specific conditions. Waste management consists of "good housekeeping" practices which are dependent upon the type of construction and the quantity and type of building materials. The following provides a method of selecting BMPs oapplicable local manuals which list common n sites along with design criteria for each BMP. There may also be state BMPs for your region. In preparing the SWPPP, the designer must first use the brnp selection guide to determine BMPs applicable to the site. The fact sheets following the selection guide detail the design and maintenance requirements, limitations, and purpose of each design and the techniques. These provide the tools for the designer to select the appropriate BMPs and locate them onsite to effectively reduce sediment loss and erosion. Information is also provided on maintenance of the control devices as well as what should be checked during required inspections. • • BMP SELECTION GUIDE Erosion Control These B'MPs protect the soil before erosion occurs. They are primarily used around areas of construction to either limit the flows across the site or limit the erosion in areas distributed but not active. BMP Name Primary Purpose Interceptor Swale Route flows around areas of disturbance Diversion Dike l Route flows around areas of disturbance Pipe Slope Drain Route overland flow on a slope into a pipe to protect the slope Rating Very Effective Very Effective Effective Vegetation Provide natural soil protection through seeding, hydromulch or phasing Mulching Protect disturbed soil with a layer of hay Erosion Control Mats Protect disturbed soil or slopes with geotextile and biodegradable fabrics Very Effective Very Effective Effective SEDIMENT LOSS PREVENTION Construction activities normally result in disturbance on the site due to grading operations, clearing and other operations. Erosion will occur in these disturbed areas and BMPs must be used to contain the sediment from these disturbed areas. The following techniques reduce soil loss from the site by retaining the soil through sedimentation or filtration of the runoff. BMP Name Silt Fence Straw Bales Primary Purpose Slow and filter runoff to retain sediment Slow and filter runoff to retain sediment Rating Effective Effective • Sediment Basin Large pond with controlled outflow which allow sediment to settle out of runoff Very Effective and strongly recommended for sites larger than 10 acres Temporary Sediment Tank Provide sedimentation for sediment laden runoff from trenches and depressed areas Stabilized Construction Entrance Sandbag Berm Reduces offsite sediment tracking from trucks and construction from equipment Provide sedimentation and filtration for runoff under concentrated conditions in creeks, channels and drainage swales Effective for specialized application Moderate Effectiveness but required to address offsite tracking Effective for severe applications WASTE MANAGEMENT These techniques will be used on the majority of construction projects due to their general topic of reducing waste from construction activities. They form the basis of general housekeeping procedures which should be followed during construction. BMP Name Solid Waste Mange Primary Purpose Rating Techniques for management of paper, packaging, general building materials, etc. Hazardous Waste Management Concrete Waste Management Management of paints, chemicals, fertilizer, oil and grease, etc. Very Effective Very Effective Disposal of concrete washout, demolished concrete, etc. Very Effective Interceptor Swale Description An interceptor swale is a small v -shaped or parabolic channel which collects runoff and directs it to a desired location. It can either have a natural grass lining or depending on slope and design velocity, a protective lining of erosion matting, stone or concrete. Primary Use The interceptor can either be used to direct sediment laden flow from the disturbed areas into a controlled outlet or to direct `clean' runoff around disturbed areas. Since the swale is easy to install during early grading operations, it can serve as the first line of defense in reducing runoff across disturbed areas. As a method of reducing runoff across the disturbed construction area, it reduces the requirements of structural measures to capture sediment from runoff downstream of the disturbed area, runoff can be directed into a sediment basin or protect inlet for sedimentation as opposed to long runs of silt fence, hay bales or other filtration method. Based on site topography, swales can be effectively used in combination with diversion dikes. Applications Common applications for interceptor swales include roadway projects, site development projects with substantial offsite flow impacting the site and sites with large area of disturbance. It can be used in conjunction with diversion dikes to intercept flows. Temporary swales can be used throughout the project to direct flows from staggering areas, storable and fueling areas along with specific areas of construction. Note that runoff which crosses disturbed areas or is directed in unstable swales must be routed into a treatment BMP such as a sediment basin. Grass lined swales are an effective permanent stabilization technique. The grass effectively filters both sediment and other pollutants while reducing velocity. Design Criteria i Maximum depth of flow in the swale shall be 1.5 foot based on 2 year design storm peak flow. Positive overflow must be provided to accommodate larger storms. Side slopes of the swale shall be 3:1 or flatter. • The minimum required channel stabilization for grades less than 2 percent and velocities less than 6 feet per second shall be grass. For grades in excess of 2 percent or velocities exceeding 5 feet per second, stabilization in the form of high velocity erosion control mats, 3" layer of crushed stone or rip rap is required. Velocities greater than 12 feet per second will require approval by the local jurisdiction and is discouraged. • • • ▪ Check dams can be used to reduce velocities in steep swales. See check dam BMP for design criteria. ▪ Interceptor swales must be designed for flow capacity based on Manning's Equation to insure a proper channel section. Alternate channel sections may be used when properly designed and accepted. ▪ Consideration must be given to the possible outlet. ▪ Swales must maintain positive grade to an acceptable outlet. Limitations Interceptor swales must be stabilized quickly upon excavation so as not to contribute to the erosion problem they are addressing. Swales may be unsuitable to the site conditions (too flat or steep) . Limited flow capacity for temporary swales. For permanent, the 1 foot maximum depth can be increased as long as long provisions for public safety are implemented. Maintenance Requirements Inspection must be made after each significant (0.5" or greater) rain event to locate and repair any damage to the channel or to clear debris or other obstructions so as not to diminish flow capacity. Damages from normal construction activities or storms such as tire ruts or disturbance of stabilization of the swale shall be repaired as soon as practical Diversion Dike Description A diversion dike is a compacted soil mound which redirects runoff to a desired location. The dike is typically stabilized with natural grass for low velocities or with stone or erosion control mats for higher velocities. Primary Use The diversion dike is normally used to intercept offsite flow upstream of the construction area and direct the flow around the disturbed edirnentlt can also be reduction device used uch as a sedimentasin or down stream of the construction area to direct flow into protected inlet. The diversion dike serves the same purpose and, based on the topography of the site, can be used in combination with an interceptor swale. • Applications By intercepting runoff before it has a chance to cause erosion, diversion dikes are very effective in reducing erosion at a reasonable cost. They are applicable to a large variety of projects including site developments and linear projects such as roadw ays for and pipeline construction sites construction. Diversion dikes are normally used as perimetercontrols with large amounts of offsite flow from neighboring properties. Used in combination with swales, the diversion dike can be quickly installed with a minimum of equipment and cost, using the swale excavation as the dike. No sediment removal technique is required prior to crossing disturbed areas. Significant savings in structural controls can be realized by using diversion dikes to direst flow to central area such as a sediment basin or other sediment reduction structure if the runoff crosses disturbed areas. Design Criteria • The maximum contributing drainage area should be 10 acres or less depending on site conditions. • Maximum depth of flow at the dikes shall be 1 foot. ■ The maximum width of the flow at the dikes shall be 20 feet. 1 Side slopes of the diversion dike shall be 3:1 or flatter. • Minimum width of the embarkment at the top shall be 2 feet. ▪ Minimum embarkment height shall be 18 inches as measured from the toe of slope on the upgrade side of the berm. ▪ For velocities of less than 6 feet per second, the minimum stabilization for the dike and adjacent flow areas is grass or erosion control mats. For velocities greater than 6 feet per second, stone stabilization or high velocity erosion control mats should be used. Velocities greater than 12 feet per second must be approved by the local jurisdiction. • The dikes shall remain in place until all disturbed areas which are protected by the dike are permanently stabilized unless other controls are put into place to protect the site. Limitations Compacted earth dikes require stabilization immediately upon placement to the problem they are addressing. The diversion dike can be a hindrance to construction equipment moving their locations must be carefully planned prior to installation. so as not to contribute on the site, therefore Maintenance Requirements Dikes must be inspected on a regular basis to determine t shall be removed�n a up trriely manner ehind the dike, If or if erosion is occurring on the face of the dike. erosion is occurring on the face of the dike, the slopes of the face shall either be stabilized through mulch or seeding or the slopes of the face shall be reduced. Pipe Slope Drain Description A pipe slope drain is a temporary pipe line typically utilizing flexible pipe that conveys runoff down unstable slopes. They are anchored on each end with some form of headwall to limit erosion and secure the pipe. Primary Use A pipe slope drain is used on sites with a long, unstable slope ea which t isssubject to y u s ion from overland flow crossing unstable or poorly stabilized slopedareas. combination with interceptor swales or diversion dikes to direct the flow into the pipe area. The pipe slope drain can provide service for a relatively large area. It does not treat the runoff, therefore if the runoff contains sediment, treatment through a controlled outlet will be required before the flow is released offsite. Applications Sites with large berms or grade changes such as roadway the flow ents are o the pipe id at s for a pipe slope drain. Since provisions must be made to direct e grading is normally required upstream of the pipe slope drain. Installed properly, slope erosion can be greatly reduced (but not entirely eliminated) through the use of the drain. Pipe slope drains also require a stabilized outlet. This is critical since the velocities at the outfall are normally high. Velocity dissipaters as well as stone or concrete rip rap are typically required om a to e required to reduce the velocity and spread the flow, reducing educi egersoion. Flowdiwsignn aipi or p drain should be routed to a controlled outlet through interceptor other suitable methods. Design Criteria ▪ The entrance to the pipe slope drain shall be a standard pre -fabricated flared end section with an integral toe plate extending a minimum of 6 inches from the bottom of the end section. The grade of the entrance shall be 3 percent maximum. ilk All sections of the pipe slope drain shall be connected using watertight collars or gasketed watertight fittings. • All sediment -laden runoff conveyed by the pipe slope drain shall be directed to sediment trapping facility. ■ Temporary pipe slope drains are to be sized to accommodate runoff flows equivalent to • • a 10 year storm as calculated using the Rational Method f d Manwin table equation, but in no case shall . i. es be sized smaller than is shown in h Maximum Contributing Drainage Area ■ Maximum drainage area for individual pipe slope drains shall be 5 acres. For areas larger than 5 acres, additional drains shall be added. ■ Both the entrance and out fall of the pipe slope drain should bebiproperly y su stabilizeasd. r Grass can normally be used at the entrance, but type one or concrete rip rap is normally used to address the high velocities of the outfall. Limitations • Drains must be located away from the construction areas since the drain can easily be damaged by construction traffic. ▪ Securing the pipe to the slope can be difficult and require significant maintenance during the life of the system. causing i es can become � In situations where pipe slope drainsconvey sediment-laden clogged during large rain events g watero overtop the diversion dike thereby creating a serious erosion condition. ▪ Grading is normally required upstream of the pipe slope drain in order to direct flow into the system. This can cause additional cost and maintenance. a A pipe slope drain reduces erosion but does not prevent it or reduce the amount of sediment runoff. Additional measures should be used in conjunction with the pipe slope drain to treat the flow. Maintenance Requirements ocate Inspection must be made of the pipe after each sufficient (> 0.5 inch) rain event loc has and repair any damage to joints or clogging of the pipe. In cases where the diversion deteriorated from around the entrance of the pipe, it may be necessary to reinforce the dike f with sandbags or to install a concrete collar to prevent failure. Signsihe area erosion er©ound the ppipe drain should be addressed in a timely manner by stabilizing mats, crushed stone, concrete or other acceptable methods. • • Vegetation Description Vegetation, as a Best Management Practice, is the sowing of annual grasses, small grains or legumes to provide interim vegetation stabilization for disturbed areas. Primary Use Vegetation is used as a temporary or permanent stabilization technique for areas disturbed by other structures. As a temporary control, vegetation is used to stabilize stock piles and barren areas which are inactive for long periods of time. As a permanent control, grass and other vegetation provide for good protection for the soil along with some filtering for overland runoff. Subjected to acceptable runoff velocities, vegetation can provide a good method of permanent storm water management as well as a visual amenity to the site. Vegetation can be used in conjunction with other techniques in order to assist in establishment of the vegetation. These other techniques include erosion control matting, swales and dikes to direct flow around newly seeded areas and proper grading to limit runoff velocities during construction. Applications Vegetative techniques can and should apply to every construction project with few exceptions. Vegetation effectively reduces erosion in swales, stock piles, berms, mild to medium slopes and along roadways. Vegetative strips can provide some protection used as a perimeter control for utility and site development construction. In many cases, the initial cost of temporary seeding may be prohibitive for stockpiles or other barren areas subject to erosion yet inactive. This initial cost should be weighed with the amount of time the area is to remain inactive, since maintenance cost for vegetated areas is much less than most structural controls. Design Criteria Surface Preparation • Interim or final grading must be completed prior to seeding, minimizing all steep slopes. • Install all necessary erosion structures such as dikes, swales, diversions, etc., prior to seeding. • Groove or furrow slopes steeper than 3:1 on the contour line before seeding. • Seed -bed should be well pulverized, loose and uniform. • • • Plant Selection, Fertilization and Seeding ▪ Use only high, USDA certified seed. ▪ Use an appropriate species or species mixture adapted to local climate, soil conditions and season according to the following table. Consult with the local office of the U.S. Soil Conservation Service (SCS) or Engineering Extension service as necessary for the selection of proper species and application technique in this area. Seeding rate should be in accordance with the following table or as recommended by the SCS or engineering extension service. a Fertilizer shall be applied according to the manufacturer's recommendation with proper spreader equipment. Typical application rate for 10-10-10 grade fertilizer is 700-1000 lb/acre. DO NOT OVER APPLY FERTILIZER.. ▪ If hydro -seeding is used, do not mix seed and fertilizer more than 30 minutes before application. ▪ Evenly apply seed using cyclone seeder, seed drill, or hydro seeder. ▪ Provide adequate water to add in establishment of vegetation. ■ Use of appropriate mulching techniques. Limitations Vegetation is not appropriate for areas subjected to heavy pedestrian or vehicular traffic. As a temporary technique, vegetation may be costly when compared to other techniques. Vegetation is not appropriate for rock, gravel or course grained soils unless 4"-6" is applied. Maintenance Requirements Protect newly seeded areas from excessive runoff and traffic until established. A watering and fertilizing schedule will be required as part of the SWPPP to assist in the establishment of the vegetation. Mulching Description Mulching is a layer of straw or other material which is spread uniformly over barren areas to reduce the effects of erosion from rainfall. Types of mulch include organic materials, straw, wood chips, bark or other fibers, decomposed granite, and gravel. Primary Use Mulch is used to temporarily and/or permanently stabilize clear or freshly seeded areas. It protects the soil from erosion and moisture loss by leasing the effects of wind, water, and sunlight. It also decreases the velocity of sheet flow, thereby reducing the volume of sediment- • • laden water flow leaving the mulched area. Applications Mulch may be used on any construction -related disturbed area for surface protection including: Freshly seeded or planted areas, Areas at risk due to the time period being unsuitable for growing vegetation, Areas that are not conductive to seeding or planting. Design Criteria Mulch may be used by itself or in combination with netting or other anchors to promote soil stabilization. Several manufactures provide organic mulch with an attached netting to simplify installation. Installation requirements should adhere to manufacture's specifications and requirements. Choice of mulch depends largely on slope, climate, and soil type in addition to availability of different materials. Straw and hay are the recommended choice due to their availability and biodegradability. Mulch should be applied in an even and uniform manner where concentrated water flow is negligible. In the North Central Texas area, the application of mulch should be approximately 2 tons dry per acre spread uniformly across the disturbed area. For areas using straw mulch and the slope is greater than 3-5%, anchoring of the mulch with a Krimper Tool is required. Limitations Mulches are subject to removal by wind or water under severe climatic conditions. Mulches lower the soil temperature which may result in longer seed germination periods. Maintenance Requirements Mulched areas must be inspected on a weekly basis, and after significant rainfall, for thin or bare spots caused by natural decomposition or weather related events. Mulch in high traffic areas should be replaced on a regular basis to maintain uniform protection. • • Erosion Control Mats Description An Erosion Control Mat (ECM) is a geotextile or biodegradable fabric placed over disturbed areas to limit the effects on erosion due to rainfall impact and runoff across barren soil. Erosion control mats are manufactured by a wide variety of vendors addressing a wide variety of conditions such as vegetation establishment and high velocity flow. Types of matting include organic (jute, straw) and synthetic (excelsior and fiber glass) materials. Primary Use Mats can be provided both temporary andlor permanent stabilization for disturbed soil or barren areas. It is used for difficult to stabilize areas such as steep slopes, temporary or permanent drainage swales, embankments or high traffic (pedestrian) areas. Some mats are reusable, reducing the initial cost of the instillation. Applications Mats can be used on any construction -related disturbed area, but are particularly effective for erosion control of fine grained soils, and on short, steep slopes (such as stream banks) where erosion is high and growth of vegetation is slow. Design Criteria A mat may be used by itself or in combination with netting other anchors to promote soil. stabilization. Choice of matting depends largely on slope, climate, soil type, and durability. Mats are usually installed to the manufacturer's recommended guidelines. After appropriate instillation, the matting should be checked for: uniform contact with the soil; security of the lap joints; and flushness of the staples with the ground. Manufacturers information will verify acceptable applications for a particular product. Limitations Although matting is highly effective in controlling erosion, it may be less cost-effective than other BMPs for erosion control and it requires a contractor with considerable mat installation experience for installation. Maintenance Requirements Matted areas must be inspected on a weekly basis, and after significant rainfall, for bare spots caused by weather related events. Missing or loosened matting must be replaced or re- anchored. Silt Fence Description A silt fence consists of geotextile fabric stretched between soil. The fence is typien or cally posts with the lower edge of the fabric securely embedded in downstream of disturbed areas to intercept runoff in the form of sheet flow. Silt fence provides both filtration and time for sedimentation to reduce sediment and it reduces the velocity of the runoff. Properly designed silt fence is economical since it can be relocated during construction and reused on other projects. Primary Use Silt fence is normally used as a perimeter control for downstream of construction sites. It is only feasible for non -concreted, sheet flow conditions. Applications es Silt fence is an economical means to treat overland, for both osite developments flows for all pend of projects. Silt fences are used as perimeter control linear (roadway) type projects. They are most effective with coarse to silty soil types. Due to the potential of clogging, silt fence should not be used with clay soil types. In order to reduce the length of the silt fence, it can be placed adjacent to the downstream side of the construction activities. Design Criteria O Fences are to be constructed along a line of constant elevation (along a contour lime). • Maximum slope adjacent to the fence is 1:1. • Maximum distance of flow to the silt fence shall be 150 feet. • Maximum concentrated flow to silt fence shall be I CFS. • If 50% or less of the soil, by weight, passes the U.S. Standard sieve No. 200, Select the Equivalent Opening Size (E.O.S.) to retain 85% of the soil. • Maximum EOS shall be 70 (#70 sieve). U Minimum EOS shall be 100 (#100 sieve). ■ If 85 % or more of soil, by weight, passes the U.S. Standard sieve No. 200, silt fences shall not be used due to clogging. ■ Sufficient room for the operation of sediment removal equipment shall be provided between the silt fence and other obstructions in order to properly maintain the fence. • The ends of the fence shall be turned upstream to prevent bypass of storm water. • • • Limitations Minor ponding will occur at the upstream side of the silt fence resulting in minor localized flooding. Fences which are not constructed on a level contour will be overtopped by concentrated flow resulting in failure of the filter fence. Silt fences subject to areas of concentrated flow (waterways with flows >1 cfs) are not acceptable.. Silt fence can interfere with construction operations, therefore planning of access routes onto the site is critical. Silt fence can fail structurally under heavy storm flows, creating maintenance problems and reducing the effectiveness of the system. Maintenance Requirements Inspections should be made on a regular basis, especially after a large storm events. If the fabric becomes clogged, it should be cleaned or if necessary, replaced. Sediment should be removed when it reaches approximately one-half the height of the fence. Straw Bale Dike Description A straw bale dike is a temporary barrier constructed of straw bales anchored with wood or steel posts, which is used to intercept sediment -laden runoff generated by small disturbed areas. The hay bales can serve as both a filtration device and a damldike device to treat and redirect flow. Primary Use A straw bale dike is used to trap sediment -laden storm runoff from a small drainage areas with relatively level grades, to allow for reduction of velocity thereby causing sediment to settle out. Applications Straw bale dikes are used to treat flow after it leaves a disturbed area on a relatively small (< acre) site. Due to the limited life of the hay bale, it is cost effective for small projects of a short duration. The limited weight and strength of the hay bales makes it suitable for small, flat (<2 percent slope) contributing drainage areas. Due to the problems with the straw degradation and The lack of uniform quality in hay bales, their use is discouraged except for small residential application. Straw bales can also be used as check dams for small watercourses such as interceptor swales and borrow ditches. Due to the problems in securely anchoring the bales, only small watercourses can effectively use hay bale check dams. Design Criteria ▪ Straw bale dikes are to be constructed along aline of constant elevation (along a contour line) . ▪ Straw bale dikes are suitable only for treating sheet flows across grades of 2% or flatter. ■ Maximum contributing drainage area shall be 0.25 acre per 100 linear feet of dike. ■ Maximum distance of flow to dike shall be 100 feet. s Dimensions for individual bales shall be 30 inches minimum length, 18 inches minimum height, 24 inches minimum width and shall weigh no less than 50 pounds when dry. ▪ Each straw bale shall be placed into an excavated trench having a depth of 4 inches and a width just wide enough to accommodate the bales themselves. • Straw bales shall be installed in such a way that there is no space between bales to allow for any kind of seepage. ■ Individual bales should be held in place by no less than two wood or steel stakes driven a minimum distance of 6 inches into undisturbed ground, with the first stake driven at an angle toward the previously installed bale. l~ The ends of the dike shall be turned upgrade to prevent bypass of storm water. Limitations Due to a short effective life caused by biological decomposition, straw bales must be replaced after a period of no more than 3 months. During the wet and warm seasons, however, they must be replaced more frequently as is determined by frequent inspections. Straw bale dikes are not recommended for use with concentrated flows of any kind except for small flows in which they can serve as a check dam. The effectiveness of straw bales in reducing sediment is very limited. Improperly maintained, straw bales can be a negative impact on the water quality of the runoff. Maintenance Requirements Straw bales shall be replaced if there are signs of degradation such as straw located down stream from the bales, structural deficiencies due to rotting straw in the bale or other signs of • deterioration. Sediment should be removed from behind the bales when it reaches a depth of approximately 6 inches. If the bales become clogged they should be replaced immediately, Sediment Basin Description. A sediment basin is a pond area with a controlled outlet in which sediment -laden runoff is directed to allow settling of the suspended sediment from the runoff. It provides treatment for the runoff as well as detention and controlled release of runoff, minimizing flood impacts downstream. Primary Use Sediment basins should be used for all sites with adequate open space to site the basin. for sites with disturbed areas of 10 acres and larger in a common drainage area sediment basins are required as either temporary or permanent controls unless specific site conditions limit their use. • Applications Sediment basins serve as treatment devices which can be used on a variety of project types. It is normally used in site development projects in which large areas of land are available for the basin, a stream or drainage way crosses the site, or a specific water feature is planned for the site. Sediment basins are highly effective for the design storm conditions. It is also reduces maintenance requirements due to the central location of the sediment and minimal structural requirements of the basin. • Design Criteria • Maximum drainage area contributing to the basin shall be 100 acres. ■ Minimum drainage of the basin shall be 3600 cubic feet per acre of contributing drainage area. • Deposited sediment shall be removed when the storage capacity of the basin has been depleted by one-half. ■ Minimum width of the embankment at the top shall be 8 feet. • Minimum embankment slope shall be 3:1. • Maximum embankment height shall be 6 feet measured from the toe of slope on the downstream side. • The basin outlet shall be designed to accommodate a 10 year design storm without causing damage to the containment structure. • Minimum outlet capacity shall be 0.2 CFS per acre of contributing drainage area. • The basin roust be laid out such that the effective flow length of the basin should be at • • least twice the effective flow width. A design worksheet is provided in Appendix A based on U.S. Soil Conservation Service TR -55 for proper design of sediment basin. Limitations Sediment basins can be rather large depending on site conditions, requiring the use of expensive development area and comprehensive planning for construction phasing prior to implantation. Storm events which exceed the design storm event can cause damage to the spillway structure of the basin. Maintenance Requirements Sediment shall be removed and the basin shall be regarded to its original dimensions at such point where the capacity of the impoundment has been reduced to one-half of its original storage capacity. The removed sediment shall be stockpiled or redistributed in areas which are protected from erosion. The basin outlet structure and emergency spillway (if present) should be checked frequently and after each major rain event to check for damage and to insure that obstructions are not diminishing the effectiveness of the structures. Sand Bag Berm Description Sandbag berms consist of stacked sandbags installed across a watercourse to direct flow downstream of disturbed areas. There are overflow pipes located in the top of the berm to allow controlled outflow of water after sedimentation has occurred. Primary Use A sandbag berm is a temporary sediment control method that address the problem of construction in creeks, channels and other watercourses which carry a constant flow and is subjected to high, concentrated flows. A sandbag berm can also be used to create a small sedimentation pond prior to the completion of a permanent detention basin. Sandbag berms can be used as check dams in temporary swales or borrow ditches. 4111 Sandbag berms are not suitable for typical perimeter controls where sheet flow is prevalent. Applications During utility or any type of construction in channels or stream beds, sandbag berms can be used as check dams across channels or stream beds, sandbag berms can be used as check dams across channels, serve as a barrier for utility trenches or even provide a temporary channel crossing for construction equipment without seriously affecting stream conditions. Sandbag berms can also be installed parallel to the road providing a corridor of sediment control similar to that provided by a silt fence or hay bales with the exception that a sand bag dike is capable of controlling much higher flows and is much more durable. For site construction sandbag berms can be used to divert or direct flow or create a temporary sediment basin with the added dimension of being able to be moved to accommodate changes in construction much more easily than compacted earth berms. Design Criteria ▪ Dikes are to be constructed along level contours for use as perimeter control devices. i Maximum flow through rate shall be 0.1 CFS per square foot of berm surface. ■ Minimum height shall be 18 inches. ▪ Minimum width of the berm shall be 18 inches at the top and 48 inches measured at the bottom. Maximum side berms shall be 2:1. >� Sandbags shall consist of polypropylene, polyethylene or polyamide woven fabric with a minimum unit weight of 4 ounces per square yard, a mullen burst strength of 300 psi minimum and ultraviolet stability exceeding 70 percent, and shall be filled with coarse sand or pea gravel. a 4" diameter SDR -35 or greater PVC pipe segments approximately 24 inches in length shall be used immediately below the top layer of sandbags to allow for overflow of the berm. ■ For severe velocities or high flows, woven mesh wire can be used to maintain the integrity of the berm. i Sufficient room for the operation of sediment removal equipment shall be provided between the berm and other obstructions in order to properly remove sediment. ■ The ends of the berm shall be turned upgrade or shall tie into natural grades to prevent bypass of stormwater. Limitations Sandbag berms are a costly, labor intensive technique which is suitable only for areas subjected to high concentrated flows. The permeability of the berms makes it unsuitable for low flow, perimeter conditions. Ponding will occur directly upstream from the berm creating the possibility of a flooding concern which should be considered prior to its placement. For sandbag berms located in high flow areas such as a creeks, the potential for berm damage during high flow increases the requirement for maintenance. Maintenance Requirements Inspections should be made on a daily basis and after each rain event. The sandbags shall be reshaped or replaced as needed during the inspection. Silt should be removed when it reaches a depth of six (6) inches. In addition, regular inspections should be made on the PVC pipe segments to assure clear flow. • • INSPECTION REPORT Area Inspected Date Name of Inspector Title Observal SECTION C • • • BMP DIAGRAMS • • • • SMP DIAGRAMS EROSION CONTROL MATS MULCHING SAND BAG BERM HAY BALE DIKE SILT FENCE SEDIMENT BASIN WATERBREAK CONSTRUCTION BROAD BASED DRAINAGE DIP CULVERT CONSTRUCTION LOW WATER CROSSING DRAINAGE DIP • I I P%1 TO° IA ~� EROSION CONTROL MATS Iii F1L BUYS\E-6 ORM1ED BY: DOC MATE: 2/14/77 FLOWUNE OF CHANNEL OR SWALE FU.: BUYS\S-e NAFFED BY: ODG BATE. 2/17/Q7 NOT TO SCALE • FLOW FLOW : 1 : `C : 1 : 1 `k : 1 I:I'�I:i:t 1:i1 ii:1: I:I: 1: I:I't:1:1:1:1: 4" VERTICAL FACE EMBEDDING DETAIL TWO STAKES PER BALE (STAKES 6 MIN.
