Southern Products and Silica Company is located directly south of, and adjacent to, Drowning Creek on the west side of US Highway 1, in northeastern Richmond County, NC (Figure 1). The mine site is located adjacent to forested wetlands, as described in the permit documentation dated 22 October 1990 by J.H. Carter III. Existing trees growing on wetlands onsite include swamp blackgum (Nyssa biflora), bald and pond cypress (Taxodium distichum and T. ascendens), red maple (Acer rubrum), sweetgum (Liquidambar styraciflua), tulip poplar (Liriodendron tulipifera), pond and loblolly pines (Pinus serotina and P. taeda) and Atlantic white cedar (Chamaecyparis thyoides). Wetland mitigation activities at the mine in 2008 consisted of collecting annual vegetation and soil data from 1 monitoring plot and soil sample analysis. WETLAND MITIGATION ACTIVITIES Wetland mitigation activities in 2008 took place at the Mushroom Fan site, which is within the Rankin lease area at the mine (Figure 2). Activities consisted of assessing survival of planted seedlings, wetland vegetation and soil monitoring and collection of soil samples for analysis. ' Figure 1. Location of the Southern Products and Silica Company mine site, near Hoffman, Richmond County, North Carolina. M m = w VEGETATION MONITORING ACTIVITIES Vegetation monitoring plots were established in 2 undisturbed wetland areas adjacent to the mine site in 1992 in order to monitor the success of the wetland mitigation activities (Figure 2). These plots (Reference Forest Ecosystems (RFE)) serve as a reference for the mitigation areas and were monitored for the 14th year in 2005. In addition to the RFEs, mitigation monitoring plots (Reclamation Monitoring Plots (RMP)) were established on the original Tyner Lake Fan-West in 1992 (RMP #1), on the Rankin Lake Fan in 2001 (RMP #2), on the Tyner Lake Fan-East in 2002 (RMP #3) and on the Mushroom Fan in 2006 (RMP #4) (Figure 2). Data were collected at RMP #4 in 2008. Restoration of RMP #1 has been completed and no plot data have been collected since 2003. RMPs #2 and #3 were released from monitoring in 2007 (Appendix A). Restoration at these sites is considered completed and no data were collected in 2008. Reference Plot Data Collection: RFE plot data was last collected in 2005. Since species composition in the 2 RFE plots has not shifted significantly in the last 10 years of monitoring, annual data are no longer collected, however, we visit the RFE plots each year during the monitoring period (between June and October) to note any major changes. RFE Plot #1 has undergone some cover changes due to a storm event in 2000 and a prolonged drought. No major changes to the RFE plots were noted in 2008. RFE #I: Dominant tree species in RFE Plot #1, located in an Atlantic white cedar stand (Figure 2), consisted of Atlantic white cedar, red maple, sweetbay magnolia (Magnolia virginiana) and tulip poplar (Tables 1 and 3). Dominant shrub species were fetterbush (Lyonia lucida), sweet gallberry (Ilex coriacea) and red bay (Persea borbonia). Dominant herbaceous species were cinnamon fern (Osmunda cinnamomea) and netted chain-fern (Woodwardia areolata). Dominant non-flowering ground cover species were peat moss (Sphagnum sp.) and common liverwort (Marchantia polymorpha). RFE #2: Dominant tree species in RFE Plot #2, located in the cypress-gum swamp adjacent to Drowning Creek (Figure 2), consisted of swamp blackgum, red maple and sweetgum, 4 Table 1.

Dominant shrub species were sweet pepperbush (Clethra alnifolia), titi (Cyrilla racemiflora), Virginia-willow (Itea virginica) and American holly (Ilex opaca). Dominant herbs and vines were sedges (Carex spp.), elongated lobelia (Lobelia elongata), netted chain-fern, cross-vine (Bignonia capreolata) and laurel-leaf greenbrier (Smilax laurifolia). Other ground cover species included mosses and liverworts. Mitigation Plot Data Collection: RMP #4: Data from RMP #4, located on the Mushroom Fan (Figure 2), were collected for the 3rd year in October 2008 (Tables 2 and 3). Planted bald cypress and swamp blackgum were present in RMP #4 and each accounted for 1-2% cover. Both herbaceous cover and species diversity here increased since 2007. Approximately 15% of the monitoring plot consisted of bare ground and/or standing water, compared with approximately 25% in 2007. Six (6) new species were recorded in 2008: bushy bluestem (Andropogon glomeratus), Canadian rush (Juncus canadensis), small-headed beaksedge (Rhynchospora microcephala), giant plumegrass (Saccharum giganteum), horned bladderwort (Utricularia cornuta) and a yellow-eyed-grass (Xyris sp.). The dominant herbaceous species in RMP #4 were small-fruit spikerush (Eleocharis microcarpa) and Canadian rush, each with 10-25% cover and wool grass (Scirpus cyperinus) with 5-10% cover. Broom-sedge (Andropogon virginicus), cypress witchgrass (Dichanthelium dichotomum), slender fragrant goldenrod (Euthamia minor), narrowleaf seedbox (Ludwigia linearis), clustered beaksedge (Rhynchospora glomerata) and Richard's yellow-eyed-grass (Xyris jupicai) each covered approximately 2-5% of the monitoring plot (Table 2). PLANTING Planting methods were similar to those described in our 1993 report (1993 Reclamation Report--Southern Products and Silica, Inc., Hoffman, NC, Wilds et al. 1993). In general, bald cypress and swamp blackgum were planted with 8 to 10 foot spacing between the trees. Atlantic white cedars were planted in clumps of 5 with 6 - 8 feet between each tree. A fertilizer tablet was placed with each planted seedling. 6 Table 2.

This fan was initially planted in January and March 2006 with 400 bald cypress, 800 swamp blackgum, 450 Atlantic white cedar and 400 pond pine seedlings. In addition, 100 bald cypress, 100 swamp blackgum and 125 Atlantic white cedar were planted in February and March 2007. No seedlings were planted in 2008. Seedlings planted within the 10 x 10-meter (0.025 acre) vegetation monitoring plot (RMP #4) were mapped and counted in order to track their survival in the future. In October 2008, there were 6 bald cypress, 4 swamp blackgum and 1 Atlantic white cedar in the plot, which equates to 440 trees per acre. No new trees were recorded in RMP #4 in 2008. Additional trees will be planted as needed during the monitoring period. SOIL SAMPLING Hue, value and chroma readings were taken from 1 site in RMP #4 on 23 October 2008. The sample taken from RMP #4 was saturated at the surface with a low chroma and some organic streaking, however, it will take many years to develop characteristics similar to the RFE soils (Table 4). Some of the plot was inundated with 2 - 5 inches of water. Additional soil samples were collected from the Mushroom Fan for an in-depth analysis for the first time in 2008. Parameters tested included hue, value, chroma, pH, Cu, Zn, Mn, base saturation, P and K (Table 5). Samples were taken from 3 sites on the Mushroom Fan and compared with samples from 2 sites in RFE #1. RFE #1 was chosen as the best comparison site due to its close proximity to the Mushroom Fan. These samples were shipped to the Agronomic Division of the NC Department of Agriculture for analysis. Test results were not yet available at the time of this writing and will be reported in an addendum as soon as they become available. SUMMARY The wetland mitigation and reclamation activities for Southern Products and Silica Company are proceeding as prescribed in the approved Reclamation Plan (Carter 1989). Restoration of the Rankin Lake and Tyner Lake-East Fans was completed and these sites were released from further monitoring by the USACE and NCDWQ in 2008 (Appendix A). The Mushroom Fan mitigation area has been planted with the prescribed plant species. Survivorship is being monitored and seedlings will be replaced as necessary. 10 Table 4.

Box 891 Southern Pines, NC 28388 Re: Southern Products and Silica Inc. 2006, 2007 Wetland Mitigation and Reclamation Reports Richmond County ' DWQ # 19910168 Dear. Ms. Freeman: The Division of Water Quality (DWQ) 401 Oversight and Express Review Permitting Unit has reviewed the Monitoring Reports for the above-referenced site. Tyner Lake Fan - East and Rankin Lake Fan have been monitored for over five years. Based on ' monitoring results, both mitigation areas appear to be on a trajectory toward success as forested wetlands. Species lists, counts, and percent cover measurements indicate appropriate vegetation communities with tree densities greater than those in the reference ecosystems (RFE). While diversity ' and percent cover are lower than those parameters in the RFE plots, it is expected that time will allow the surviving planted vegetation to mature and additional desirable species to move in from nearby ' undisturbed natural communities. Both areas have been shown to have wetland hydrology, per the monitoring requirements in the approved mitigation plan, and are developing hydric soil characteristics. Tyner Fan - East and Ra4in Fan are released from further monitoring. We appreciate the fact that ' general vegetation maintenance of these sites will continue as needed over time while other mitigation areas are being developed. Any management activities should be performed with the goal of encouraging development of the targeted forested wetland communities. Mushroom Fan was established in 2005-2006. Herbaceous growth was substantial from 2006 - 2007, and an associated reduction in open water from 50 to 25 percent was observed. Two concerns were raised during review of the monitoring reports: 401 Oversight/Express Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone (919) 733-1786 / Fax (919) 733-6893 Internet: http://h2o.enr.state.nc.us/ncwetlands Nine Carolina NWA(ra!!y An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper Ms. Freeman Dr. J.H. Carter III & Associates c. Southern Products and Silica mitigation and reclamation Page 2 of 2 • 4 species of trees were planted on site, but only 2 to 3 were observed during monitoring. Was this simply because the monitoring plot did not include all of the planted species, or were pond pines and white cedars experiencing mortality throughout this mitigation area? Please comment on general site observations regarding vegetative success. Parameters related to soil color were included in the reports. The mitigation plan also includes several physical and chemical parameters, to be measured during years 1, 3, and 5 of the 5-year monitoring period. Analysis of these parameters has proven to be useful at this mitigation site in the past, indicating a need for lime application in 2002. Have these parameters been analyzed for the Mushroom Fan? If not, then the required schedule should be resumed during the upcoming monitoring year 3. Mushroom Fan will continue to be monitored through a minimum 5-year monitoring period. We look forward to receiving future monitoring reports and working with you toward success of this mitigation site.

In the report prepared by Dr. J. H. Carter and Associates, Inc., it was concluded that the vegetation and hydrological monitoring had met the success criteria set forth in the approved mitigation plan for two of the mitigation areas described in the 2007 annual Mitigation Report. Our office concurs with this determination, and has concluded that the overall objectives of the Rankin Fan and Tyner Lake Fan-East mitigation areas have been achieved. Therefore, no additional monitoring will be required on the Rankin Fan and Tyner Lake Fan-East mitigation areas. Future plans to ust the property, outside of its intended natural mitigated state, must be reviewed by our office.
