topsoil is present across the cover area. Samples will be collected on the same grid and <br /> analyzed for nutrients to ensure that proper soil amendments, if needed, are�applied. <br /> Long-term viability of the vegetative cover will be verified through annual inspections for <br /> the first three years following the season of construction. We anticipate that some weed <br /> control will be necessary as described in the operation and maintenance section below. <br /> Success of the project will be documented with sampling in 1-meter quadrates along a <br /> transect set up on the long axis of the cover. Quadrates will be placed every 50 feet_ <br /> Sampling will be performed in August of each year by the Buyers'staff or by an <br /> experienced contractor. Photographs from fixed reference points and vertical photos at <br /> each sampling point will be included in the monitoring program. Success will be <br /> considered to be achieved if 70% or more of areal coverage of the planted grasses can <br /> be documented in the third annual inspection following construction, and the vegetative <br /> community is being sustained by natural precipitation and runoff patterns. <br /> 9.6.5 Grading and Rock-Cover Construction <br /> Grading limits will be verified in the field by survey information at the time the grading is <br /> completed. The extent of rock covers over the stream-side and intermixed tailings will <br /> be determined visually by observation of the characteristic yellow color of the tailings <br /> material. Photographs of each stream-side and intermixed tailings area that is covered <br /> will be taken before construction begins and after construction is complete to document <br /> the areas covered. <br /> 9.6.6 Institutional Controls <br /> Placement of fences and signs will be documented by locating them on a map of the <br /> site. The map will be submitted as part of the completion report. The text and graphics <br /> used for the signage will be described and included in the completion report. <br /> 9.6.7 Surface-water Sampling <br /> Samples of surface water from the Swan River will be collected after completion of <br /> construction to verify continued compliance with state water-quality standards. Samples <br /> will also be collected and analyzed during the next three annual inspections and <br /> maintenance events. <br /> Surface-water samples will be collected in the Swan River channel directly across from <br /> the site and approximately% mile downstream of the site,at a point immediately <br /> upstream of the confluence with Muggins Gulch and the culverts running undemeath <br /> Tiger Road. Efforts will be made to collect samples at the same locations as RT-SW-02 <br /> and RT-SW-03 in order to ensure the comparability of sample results with site- <br /> assessment results reported in CDPHE (2002). <br /> Field parameters measured at the time of sample collection will include temperature, pH, <br /> and electrical conductivity. Samples will be submitted to a state-certified laboratory for <br /> analysis of dissolved metals. Analytes will include the same suite of metals as were <br /> used by CDPHE (2002)in the site-assessment work. The hardness of the samples will <br /> also be calculated. Concentrations of dissolved metals will be compared to hardness- <br /> adjusted table-value standards to verify continuing compliance with water-quality criteria <br /> for the reach of the Swan River adjacent to and downstream of the site. <br /> IXURoyal Tiger VCUP Application Page 31 of 33 <br />
