Peak Ranch Resource <br /> August 5,2020 <br /> 5.0 POST-RECLAMATION SITE DRAINAGE <br /> Exhibit F, Sheet F-1 shows arrows indicating the approximate direction of drainage throughout the site within <br /> the affected area. Runoff from the property located to the south of the site will continue to flow to the <br /> northwest, along the southern berm to the Blue River. Runoff from east of the project area will be conveyed <br /> under Colorado Highway 9 in culverts and then to the Blue River via the Town of Breckenridge drainage <br /> easement that bisects the site. Runoff that falls on the inside of the berms will drain into the reclaimed mining <br /> areas and the water will flow into the groundwater pond or infiltrate the underlying alluvium. Runoff that falls <br /> on the outside of the vegetated berms will ultimately flow into the Blue River. <br /> 6.0 WEED CONTROL <br /> Measures will be employed for the control of noxious weeds. A Weed Control Plan will be utilized as follows: <br /> 1. Every April and October, a weed survey will be taken of the affected area to identify and map the <br /> presence of any noxious weeds listed by the county and the state. <br /> 2. If any patches or plants are identified, they will be controlled within 30 days. This may include mowing, <br /> tillage, or spraying them with an herbicide approved for use by the weed control staff of Summit County. <br /> Other methods of weed control (i.e. biological) may be employed from time to time depending on the <br /> nature and extent of the targeted species. <br /> 3. After reclamation,weed surveys and controls will continue until the perennial vegetation cover on the site <br /> meet DRMS requirements and bond release is obtained. <br /> 7.0 REVEGETATION SUCCESS CRITERIA <br /> Revegetation will be deemed adequate when erosion is controlled, and vegetation is considered satisfactory <br /> according to Division standards. Reclamation is considered a success when a diverse and long-lasting <br /> vegetative cover is established, and the site is free of prohibited noxious weed species that seriously threaten <br /> the continued development of the desired vegetation. Monitoring the reclamation on an ongoing basis will <br /> ensure its success. If problems arise, Peak Materials will consult with the local NRCS office to get input <br /> regarding how to resolve the problem. If minor changes or modifications are suggested by the local NRCS <br /> office to the seeding or reclamation plan, revision plans will be submitted to the DRMS prior to their <br /> implementation. It is anticipated that the Division will provide both assistance and feedback in evaluating the <br /> success of the ongoing reclamation process. Information on all areas disturbed and reclaimed as well as any <br /> other important items regarding the reclamation will be submitted in the annual reports to the Division. <br /> 4rmâ–º. wki and Aswistm FLIA' E_6 O TETRA TECH <br />
