The SWPPP has been prepared in accordance with good engineering,hydrologic,and pollution control practices, and is designed to constitute compliance with Best Available Technology(BAT)and Best Conventional Technology (BCT),as mandated under the Federal Clean Water Act and the Federal Water Pollution Control Act as well as rules and regulations promulgated by the Colorado Department of Public Health and Environment. The subcontractor awarded construction will be responsible for the implementation and maintenance of this plan. HS Gathering,LLC will designated an environmental inspector that will be responsible for insuring that the construction subcontractor is following this plan. PROJECT DESCRIPTION HS Gathering, LLC is constructing the Platteville Gas Compression Facility located in Weld County,Colorado, which is associated with natural gas compressors,a dehydration unit and liquid storage facilities. The general construction sequence of the Platteville Compression Facility will consist of: • Clear and grade the project areas level,and clear and grade right of way • Trenching • Trench Backfilling • Install plant components and equipment. • Gravel or Scorio based parking lots and access areas. • Re-seed/reclaim the remaining disturbed area to restore area to previous or better condition. Total project area for the Platteville Gas Compression Facility is approximately 10 acres. The actual area of construction disturbance will be approximately 6 acres. This number could increase if the need for additional Temporary Use Areas is determined. There is no wetland acreage in the area of the Platteville Gas Compression Facility. The runoff coefficient for the project area is expected to vary between 0.10 and 0.30 and is not expected to change significantly following construction. Most of the project area is located in previously undisturbed areas of short-grass prairie. The most common substances that could be spilled within the project area are 1)diesel fuel and gasoline used to fuel construction equipment and vehicles and 2) lubricating oils used by construction equipment. No non-storm water components of storm water discharge are anticipated. The receiving water bodies for surface water drainage from the Platteville Gas Compression Facility will be the West Speer Canal and the East Speer Canal in the area of Sec. 13 T3N R66W. SITE MAPS A topographic map of the area surrounding the Platteville Gas Compression Facility is presented as Figure 1 and shows the Platteville Gas Compression Facility in relation to surrounding topographic features. Best Management Practices for Storm Water Pollution Prevention Erosion and Sediment Controls Erosion control will be accomplished through a combination of construction techniques, vegetation,and structural features. 1. Structural Practices The following are structural site management practices,which will minimize erosion and sediment transport. a. To minimize disturbance associated with installation of the Platteville Gas Compression Facility, level and gently sloping terrain outside the project area will not be graded,except where necessary for construction equipment stability and fire safety. b. Silt fences will be installed as needed on down-gradient portions of the project area. c. Side hill cuts will be kept to a minimum to protect local resources while providing a safe and stable plane for the efficient and safe use of equipment. d. Where required,erosion control structures such as water bars,diversion channels,and terraces will be constructed to divert water away from the project area and to reduce soil erosion along and adjoining areas disturbed during construction. e. In areas of steep slopes that are not annually cultivated, water bars or runoff diversions, will be installed as indicated in Table 1. Table 1 Spacing for Erosion Control Structures Slope(Percent) Diversion Spacing(Feet) 5 through 15 300 16 through 30 200 30+ 100 2.Implementation of Structural Practices a. The construction sites may have silt fences,straw bale dikes or equivalent sediment controls installed so as to protect adjacent down slope surface waters, wetlands and roads from sediment flow due to runoff from a storm event. b. For construction sites in drainage locations serving five or less acres,silt fences,straw bale dikes or equivalent sediment controls are required for all side slope and down slope boundaries of the construction area,or a detention basin providing storage for runoff from a ten year,24-hour storm event. c. For construction sites with more than five disturbed acres at one time that are served by a common drainage location,a detention basin providing storage or equivalent controls for runoff from disturbed areas from a ten-year, 24-hr storm event shall be provided where attainable. For sites with more than five disturbed acres at one time which are served by a common drainage location, where a detention basin providing storage or equivalent controls for runoff from a ten-year,24-hr event are not attainable,silt fences,straw bale dikes or equivalent sediment controls are required for all side slope and down slope boundaries of the construction area. d. All grade surfaces,walls,dams and structures,vegetation,erosion and sediment control measures and other protective devices identified in the site plan will be maintained,repaired and restored as necessary. All erosion control structures will be inspected at least every seven days and within 24 hours after storm event of 0.5 inches or more. Any deficiencies will be repaired in a timely manner. Documentation of inspections,findings and corrective actions will be maintained at the construction site. 3. Site Preparation a. Existing cover will be removed only where necessary for the operation of equipment. In general,vegetation will be cut off near ground level leaving the root systems intact. Cuttings will be distributed over reclaimed areas during reclamation or disposed of as directed by the landowner/agency representative. b. Trees and large shrubs that are not cleared from the site will be protected from damage during construction by avoiding them with equipment. For example, bull dozers will maintain their blades in a raised position except for areas designated•for clearing or to smooth out sharp breaks in relief. c. Grading outside the project area will be done only when necessary for the safe operation of equipment and for fire protection. d. Trees will be cut or trimmed only to facilitate clearing,grading,and safe installation. Trees,which must be removed will be cut. Trees outside the area of disturbance will not be cut,but will only have overhanging limbs removed by cutting, with the tree to remain. The bulldozers will maintain their blade in a raised position in these sensitive visual resource areas, where practical. 4. Excavation a. Excavated materials will be stored next to the excavation to protect the material from vehicular and equipment traffic. b. Excavation in especially sensitive areas may be conducted according to special techniques as specified by the landowner/agency representative. c. Materials excavated will be utilized as backfill when possible. An exception may be some rock excavated by blasting. In these areas,some select backfill may be required to protect the project area. Excess rock will be distributed over a portion of the project area or disposed of off-site. d. All cuts made in steep rolling terrain during construction will be regarded and contoured to blend into the adjoining landscape and to reestablish the natural drainage patterns. e. Materials that are unsuitable for use as backfill or excess backfill material will be disposed at approved locations. f. Temporary work space areas will be restored to approximate pre-construction conditions. S. Streams and Wetlands a. During construction near streams, lakes or wetlands sedimentation(detention)basins,straw bales,or fabric filters may be constructed to prevent suspended sediments from reaching downstream watercourses or lakes. • b. Disturbance of riparian and wetland areas will be kept to the minimum needed for construction and installation. Approaches to streams will involve selective clearing of vegetation. Willows and cottonwoods cleared during construction will be reestablished as part or reclamation. c. If work is required in willow/shrub type wetlands,the small trees and shrubs will be trimmed to ground line in areas where equipment will be working. d. The first 12 inches of topsoil from wetlands will be salvaged and redistributed over the trench as quickly as possible following installation of the pipeline. The seeds,roots,rhizomes,tubers,and bulbs present in the topsoil will enhance and help speed up reclamation of wetlands disturbed by construction. e. Where necessary, water bars or sediment filters,such as staked straw bales or silt fences, will be constructed adjacent to the crossings to reduce potential sedimentation in streams or wetlands. Trenching will cross dry streams. Small flowing streams will be crossed by fluming or trenching with a downstream silt barrier to reduce downstream sedimentation. Materials Handling and Spill Prevention Hazardous materials and petroleum products to be used in construction of the Platteville Gas Compression Facility are limited to fuel for construction equipment and vehicles as well as small quantities of paints and solvents. Material Safety Data Sheets(MSDSs) for materials to be used are found in the Spill Prevention,Containment,and Control Plan that will be kept on site during construction by the Environmental Inspector. Refueling and lubrication of vehicles will be conducted a minimum of 100 feet back from flowing streams and wetlands. Any spills will be promptly cleaned up and contaminated materials hauled off-site and disposed of properly. Quantities of materials on site will be limited to"as-needed"for the immediate workday underway. Other Controls All waste from materials imported to the construction site are to be removed for disposal to an appropriate licensed disposal facility including sanitary sewage facilities (typically portable). No wastes of imported materials shall be buried,dumped,or discharged to waters of the State. There are no other pollutant sources from areas other than construction expected. To prevent tracking of sediment onto public roads,the proposed facilities shall have graveled or scorio based access and exit drive areas adjacent to public roads. Maintenance Maintenance will be the responsibility of the subcontractor. Maintenance will be performed on an as-needed basis • based upon the results of inspections conducted at the site. INSPECTION 1. Inspections will be conducted at least every seven calendar days and within 24-hours of any precipitation event exceeding 0.5 inches. 2. Any inspection checklist will be filled out and these lists kept on file for three years following construction. 3. Inspection results will immediately be reported to the subcontractor for corrective action. FINAL STABILIZATION AND LONG-TERM STORM WATER MANAGEMENT 1. Reclamation a. Unless otherwise directed by the landowner or the jurisdictional authority,rocks,cut vegetation,and other surface material temporarily stockpiled for construction will be redistributed back across non-fenced portions of the project area following construction. b. Disturbed areas will be seeded using seed mixes appropriate to the location. Local soil conservation authorities with the U.S.Natural Resources Conservation Service will be consulted regarding the correct seed mix. c. On terrain where drilling seed is appropriate,seed will be planted using a drill equipped with a depth regulator to ensure proper depth of planting. The seed mix will be evenly and uniformly planted over the disturbed area. Drilling will be used where topography and soil conditions allow operation of equipment to meet the seeding requirements of the species being planted. d. Broadcast seeding will occur on steep terrain and on areas that are too rough for drilling,such as where the cut vegetation and rocks were redistributed over the right-of-way. Where broadcast seeding occurs, the rate of seeding will be doubled. e. Seeding will be done when seasonal or weather conditions are most favorable according to schedules identified by the jurisdictional authority or landowner. Whenever possible,seeding will be timed to take advantage of moisture,such as early spring or late fall to benefit from winter precipitation. f. Seed mixes will be planted in the amount specified in pounds of pure live seed/acre,where necessary. There will be no primary or secondary noxious weeds in the see mix. Commercial seed will be either certified or registered seed. g. The reestablishment of vegetative cover as well as watershed stabilization measures will be scheduled during the working season and before the succeeding winter. In any case,revegetation treatments will be accomplished as quickly as possible after facility construction. h. In general,the applicable portions of the project area will not be mulched during reclamation and revegetation. Mulch will only be applied at the request of the jurisdictional authority in areas where the cut vegetation and rocks are not redistributed over the distributed area. (The cut vegetation and rocks will act like mulch in the areas where they are applied.) Where straw of hay mulch is requested,the mulch will be applies at a rate of two tons per acre and crimped into the soil. I. The need for fertilizers will be determined in conjunction with the jurisdictional authority. If fertilization is necessary,the rates of application will be base on site-specific samples of soil. 2. Post-Construction Structural Measures a. Permanent waterbars will be installed on steep slopes according to Table 1 and at wetland and stream crossing boundaries. b. Trench plugs will be installed on steep slopes according to Table I and at wetland and stream crossing boundaries. c. After restoration work is complete,required repairs to vegetation and erosion and sediment control structures will be completed along with routine scheduled pipeline inspections and/or in response to other notification. All construction personnel will be properly trained in accordance with permit guidelines. \ _ I VICINTIY MAP 1 i as o w o / 2 1 ° frdIS 3N66W 1 Imo ` ^^0 ,m I I ° �1 s ...
