B. Monitoring Methods <br />1. Acting as the environmental consultant, WWE will conduct on-site evaluations and <br />consultation prior to and during construction, replanting, seeding operations, and <br />monitoring periods. <br />C. Vegetation <br />1. Photo points will be established at the mitigation site. Enough photo points should be <br />installed so that all portions of the reclamation/restoration areas are clearly visible and <br />progress can accurately documented (COE 2008b), at least six. Each photo plot will be <br />permanently established using Rebar, PVC or other permanently placed material, global <br />positioning system (GPS), and identified on the map with an azimuth of shot identified <br />(Figure 9). <br />2. A 20 by 50 -cm quadrant frame (or plot) will be systematically placed along permanently <br />located transects. Attributes monitored consist of canopy cover, frequency, and <br />composition (see Appendix F for Data sheets). Each plot will be individually <br />photographed. Vegetative measurements and related terminology are defined in standard <br />sampling references (Cochran 1977; Daubenmire 1959; Greig -Smith 1964). <br />D. Hydrology <br />1. Water monitoring wells will be installed to replace open pit wells currently onsite (Figure <br />10). <br />2. Water table elevation will be measured at each monitoring well beginning in early spring <br />(April 1) through the end of the hydrograph period (approximately November 15) of each <br />year. These readings will be taken approximately every two weeks throughout this <br />period. The threshold for saturation levels will be at the 12 to 18 inch sub -surface level. <br />3. Inundated areas will be recorded via GPS and mapped on a detailed hydrology map. <br />4. Soil saturation levels will be observed, i.e., capillary fringe, for the development of <br />redoximorphic features and hydrophytic root development. <br />E. Soils <br />1. Monitoring for sulfidic odor establishment as an indicator of reducing conditions. <br />2. Monitoring for positive, alpha, alpha dipiradyl test again as an indicator for reducing <br />conditions and wetland soil development. <br />3. Presence of oxidized root channel formation. As plant species composition changes, <br />changes in the soil formations will also be occurring. <br />4. Saturated conditions as a surrogate for anticipated changes in soil development, within 12 <br />to 18 inches of the water table and criteria as described above. <br />F. Annual Reports <br />1. Annual reports including a summary of observations, progress, potential problems, <br />corrective actions taken, and photo documentation will be submitted to the EPA by <br />December 1st of each year, until the site has been released by the EPA and COE. <br />WestWater Engineering Page 19 of 24 July 2012 <br />
