Stormwater Management Plan RTZ Gravel Pit Prepared fora RTZ Indus#r4 LLC P.O. BOX 1908 Glenwood Springs, CO 81602 (970) 945 -5700 Prepared by: Zancanella & Associates. Inc. 1011 Grand Avenue Glenwood Springs, CO 81601 (970) 945 -5700 INTR❑ 11MO The proposed construction of the RT2 Gravel Pit will take place on a 130 acre tract of land located 4.5 miles west of Parachute, Colorado at the intersection of Highway 6 & 24 and Stone Quarry Road. The site is bordered by the Union Pacific Rail Road line and Interstate 70 to the north, to the east by an existing gravel pit operation, to the west by undeveloped land, and to the south by the Colorado River. The project will initially involve the development of the gravel pit, including the removal and stockpile of topsoil and overburden, clearing and grubbing the area for crusher machinery and offices, and reclamation of the pit after each phase has been Fully mined. It is anticipated that reclamation will entail open water ponds, and a future development to the site may occur, but these activities are not formally proposed at this time. The implementation of this storm water management plan shall begin prior to any construction. This plan covers the mitigation of the adverse effects of storm water runoff during construction, and gravel mining and crushing operations. The owner, contractor and subcontractors will be responsible for the construction of the infrastructure and protection of adjacent water courses. Construction 5efluenCe The date for beginning construction activities is estimated to be March 2009. Implementation of the storm water, management plan is required to be in place prior to initiating construction activities. The i?1 storm water management sequence is the installation of the perimeter sediment controls such as sediment control fencing, and erosion logs and /or straw bales, followed by clearing and grubbing. The site will be developed in three phases. The phases will consist of 14.7 acres for Phase I, 9.5 acres for Phase fl, 16.5 acres for Phase Ill. This will limit the disturbed area to one third of the site at a time. As each phase has been fully developed, it will be reclaimed and revegitated before the next phase proceeds. The intent of this storm water management plan is to cover the development and operations of the three phases for the crushing activities and reclamation of the site. The construction phasing can be seen on the attached construction phasing map. (Fig. 1) The stabilization methods will be further described below. Existine Conditions The site can be broken into three parts. The upland area is dominated by scattered greasewood shrublands. This area includes the railroad right -of -way and will not be affected by the mining operations. The second part is the main area that will be mined and includes the previously disturbed and excavated borrow pits. This area also has infrequent rabbit brush and widely scattered saltbrush. As a result of the prior disturbance and the high salinity of this area it currently has a ground cover of about 20% to 30 %. r� The third area is the cottonwood riparian woodlands immediately adjacent to the Colorado River which also has tamarisk, Russian olive, and small patches of cattail. Grasses in this area were dominated by saltgrass. A wildlife study conducted by Rocky Mountain Ecological Services has identified three wetlands areas on the proposed property. These wetlands are located along the county road and the Colorado River. The gravel pit boundary has been adjusted to exclude the wetlands. Protiosed Congitigns As previously described, the proposed construction will consist of the development, operation, and reclamation of a gravel mining and crushing operation. The proposed reclaimed site will include two new ponds. (Attach reclamation plan) All other disturbed areas of the site will be revegitated to stabilize the site in the interim until the site obtains approval for a residential development. The site will be revegitated with a native seed mix in accordance with the attached seeding plan. CONSTRUCTION DEWATERING PLAN Dewatering of the gravel pit is anticipated due to shallow water table and the proximity of the gravel pit to the Colorado River. A construction dewatering permit has been submitted to the Colorado Department of Public Health and the Environment. A lined, 300 ft. by 100 ft. detention pond will be constructed on the east side of the unnamed intermittent stream as identified on the attached site map. i As each phase of the gravel pit is developed, a sump will be constructed and the water will be pumped r.; to the detention pond. The water leaving the detention pond will pass through a Parshall flume with a continuous data logger to record the water leaving the plant. The water will then flow through a series of check dams along the unnamed intermittent steam to the Colorado River. STQRMWATER L,�INOFF - DRAINAGE PLAN Stormwater runoff from this site will be, in general, unconcentrated sheet flow. The sheet flow off of the stripped land and the stockpiles will be channeled into ditches to minimize erosion. Because of the natural slope of the site, the storm water will be channeled into three outfa11 areas. These three areas are: the bar ditch alongside County Road 300, the unnamed intermittent stream on the east side of Phase II, and the unnamed intermittent stream south of the topsoil stockpile. The three outfalls will have check dams and straw bale BMP's to minimize sediment and erosion before the storm water reaches the Colorado River. A silt fence will be required along the southern edge of the gravel pit near the Colorado River to minimize sediment from entering the river from the low areas of the site. BET MANAGghdENT PRACTICES IBMPsi The following describes the site management procedures that will be implemented for the RTZ Gravel Pit site in accordance with typical Best Management Practices (BMP's). During construction activities and until vegetation can be established, temporary BMP's will be utilized to minimize the effects of j sediment erosion and to manage storm water. _ The stripping of topsail and overburden from the site will produce large stockpiles on the site. The size {{, of these stockpiles will be constantly changing as more material is removed from the site and deposited E� at the stockpile. for this reason a perimeter ditch will be a better choice than silt fence. The perimeter ditch can easily be moved and maintained as the stockpiles are moved and changed with the equipment available at the site. A ditch will be placed around the perimeter of the stockpiles to gather runoff from storm events and channel it to a detention pond. The detention pond will allow the sediment to fall out of the storm water before it enters the intermittent stream. The sides of the stockpiles will be tracked with a dozer to minimize sheet flow off the sides of the stockpiles. Erosion control logs or certified weed free straw bales will be placed at intervals of approximately 1€ 0 ft in major drainage channels/roadside ditches and at intervals of approximately 50 ft in minor drainage channels leading from culverts. They will also be placed at the and of all swales before the swales outfall into the major drainage. These controls should be sufficient to mitigate the sediment discharged into the existing system. sediment and mud shall be prevented from leaving the construction site by immediate placement of a vehicle tracking pad at entrance. The contractor is responsible for cleaning and general upkeep of existing public roads used for access. In the interim condition water trucks should be maintained and utilized onsite for the duration of the construction period to minimize potential fugitive dust caused by mining activities as an effective dust control measure. Good housekeeping BMPs should be followed throughout the entire life of the project. These include the following: - refuse receptacles should be regularly emptied and equipped with lids, - keeping machinery in good operating condition to prevent leakage. - apply appropriate (not excessive) amounts of fertilizer to the landscaping. - scheduled maintenance of BMPs and cleaning of check dams, vehicle tracking pad, and silt fence. Other housekeeping practices should include general site cleanliness and proper training of employees. Seeding of disturbed areas is needed after the completion of construction. The seeding may be only temporary if it is in areas that will contain pavement or buildings in the future. MATERIAL HANDLING AND SPILL PREVENTION if fuel or oil for construction machinery is present on the site, materials should be stored and handled in covered areas to prevent contact with stormwater, and chemicals should be stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater runoff. Cleaning and fueling of machinery should be done during dry weather, if possible. Washing of concrete trucks and other equipment into the storm drainage system is prohibited. Spills or accidents shall be immediately reported to the SWMP Administrator and depending on the nature of the spill involved, the r Colorado Department of Health, downstream users, or other agencies may need to be notified. FINAL STABALIZATION Once construction activities are completed for each phase, restoration and final stabilization of the disturbed areas will begin, Within one growing season of the project completion, uniform vegetative site coverage shall be equal to or greater than 70% of the pre- disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed, to be considered stabilized. When the site is determined to have reached the final stabilization stage, temporary erosion control measures can be removed. INM_ ERiQN AND MAINTENANCE A thorough inspection and maintenance of the storm water management system is required every 14 days and after any precipitation or snowmelt event that causes surface runoff. The permit will describe the inspection procedures to follow. As part of the inspection, a logbook needs to be kept. The following information should be included in the logbook (per "Construction Guidance Document. Preparing a Storm Water Management Plan," Colorado Department of Public Health & Environment, 7/94): - records of any spills, leaks, or overflows, including time, date and weather condition, - implementation of specific items in SWMP, events involving materials handling and storage, - contacts with regulatory agencies - maintenance and repair of storm water management controls, - preventive maintenance activities, - inspection activities and - dated photographs. RETENTION OF RECORDS The permittee shall retain a copy of the Storm Water Management Plan required by this permit at the construction site from the date of project initiation to the date of final stabilization. The permittee shall retain copies of the Storm Water Management Plan and all reports required by the permit and records of all data used to complete this application for a period of at least three years from the date of final stabilization.
