Becker Minerals was originally issued a Nationwide Permit No. 26 (Action ID No.199701563) by the Department of Army, Corps of Engineers, Wilmington District Office on February 6, 1997 to be allowed to impact 5.93 acres wetlands above the headwater of an unnamed tributary of the Upper Little River at the Harnett Quarry near Lillington N.C. One of the conditions of permit issuance was that a mitigation plan be developed for off site mitigation, at a ratio of 1:1, at the Senter Mine which is located in the Upper Little River drainage basin near Lillington, N.C. Becker Minerals engaged Environmental Services, Inc. of Raleigh to develop the required mitigation plan. The mitigation plan was approved by the Department of Army, Corps of Engineers, Wilmington District Office on October 27, 1997. The approved mitigation plan requires that annual monitoring of the created wetlands be completed by October 1 of each year and a monitoring report be submitted by December 1 of each year. 2) Hydrology of the Mitigation Site: A requirement of the mitigation plan is to demonstrate that the created wetland area will have a typical wetland hydrology. The mitigation area contains a number of surface ponds that are connected to the ground water table. The surface area of the ponds changes during the year in response to storm water runoff from areas above the mitigation site. Surface hydrology is demonstrated by the presence of the ponds. To demonstrate the presence of subsurface hydrology two sets of monitoring wells were installed within the mitigation area. A set of monitoring wells consists of four wells in a line across the mitigation area between the upland fingers. One set of wells was installed at the northern end of the mitigation area and the other set at the southern end of the mitigation area. Both sets of monitoring wells lie on a permanent monitoring transect. The monitoring wells were installed in accordance with the specifications provided by the Corps of Engineers. The monitoring wells were set to a depth of three feet below the surface. The monitoring wells have been read on a monthly basis and a copy of the readings given in the Appendix 6. The yearly (2001, 2002 and 2003) rainfall measurement data obtained in the vicinity of the mitigation area are in Appendix 5. Water levels in the monitoring wells were measured and recorded on 30 occasions throughout 2005 . 3) Monitoring Transects Lines: A total of five permanent transect lines were initially established in the wetland area in 1998. The transect lines locations were selected to be representative of all conditions that are present in the mitigation area. The transect lines generally run from an upland across the wetland to the opposite upland. In 2000 two additional transect lines were added to be representative of the areas where seedlings were planted in February 2000. (Transects F&G). A map indicating the locations of the monitoring lines is given in Appendix 7. The beginning and end of each of the transect lines are marked with a pipe driven into the ground. A plastic marker is placed at 100 foot intervals along the transect line. Each tree within 20 feet of the centerline of the transect was surveyed and marked with pink ribbon to identify it as a tree to be monitored. Trees within the monitoring zone were identified by species and the height and girth of the tree was measured and recorded. Other information recorded was if the tree was alive or dead. Table #1 summarizes the information recorded from each transect in 2005. Detailed tables of the tree monitoring results are given in Appendix 2 & 3. Photographs of the two transects appear in Appendix 8. Table 1. Summary of Tree Monitoring for 2005 Transect F G # of Planted Trees 17 19 # of Volunteer Trees 0 1 Max. Height of Trees (in) 52 40 Min.

This conclusion was reached not only by examining the growth and survival rate of the trees, but also by a comparison of the rainfall measurement data for the year 2001, 2002, 2003 and 2004. The comparison of the rainfall measurement data revealed the following: Average rainfall for North Carolina for the period from 1995 to 2005 is 51.38 inches according to NOAA Climatic Data. Total rainfall for North Carolina in 2005 was 50.27 inches. Average rainfall for the years 1995 to 2005 show higher than normal rainfall in 1995, 1996, 1998 and 2003; lower than average rainfall in 1997, 2000 and 2001 and slightly less than average rainfall in 2002, 2004 and 2005. Rainfall in 2001 was significantly less than average resulting in an overall decreasing trend in precipitation however the much higher than normal rainfall in 2003 should help to mitigate this trend. Rainfall as recorded for 2005 at the Elliott Mine operation, approximately 3 miles away, was 39.4 inches, several inches below normal. Monthly recorded rainfall is as follows (see Appendix 5 for previous years summary): Month 2005 Precipitation in. January 2.0 February 2.8 March 5.0 April 2.0 May 2.7 June 3.1 Jul 5.1 August 1.5 Se tember 1.8 October 3.0 November 5.4 December 5.3 Appendix #1 is a tabular summary of the key elements of the tree monitoring program. The 2005 data is summarized and compared to years 2002 through 2004. The 2005 percent survival was 40.5 for transect F and 35.8 for Transect G. Only 63 and 51 percent of the trees recorded in 2004, for Transects F and G, respectively, survived until the end of the growing season in 2005. Appendix #2 and Appendix #3 give individual tree monitoring results by year for Lines F and G, respectively. The average height of the trees in Transects F and G increased from 2004 to 2005, indicating continued growth of the seedlings. The average girth of the trees in Transect G increased steadily from 2004 to 2005 while average girth in Transect F was unchanged. Appendix #4 includes a graphical summary of the data from years 2000 to 2005 and Appendix 5 includes monthly rainfall data from the area from 2000 to 2005. Appendix #6 includes the 2005 well monitoring data. All of the seven wells indicated that wetland hydrology criterion of water table depth within 12 inches of the surface was being met, except for well E-4. None of the measurements taken during the growing season (March 23 - Nov 5) at E-4 showed water table depth within 12 inches of the surface. For the mitigation plan to be a success a survival rate of 320 trees per acre has to be met at the end of five years. This criterion was not met in 2005 (refer to Table #1). This is most likely attributed to the severe 2005 drought conditions present in this area, as indicated by the rainfall data, well data, and resulting tree mortality. 5) Conclusions The monitoring results for 2005 show that success criteria for the monitored wetland areas at the Senter Plant are not being met. As in the approved Senter Mine Mitigation Plan, coordination with the appropriate regulatory agencies will be undertaken to determine the most appropriate remedial action. This will mostly likely include replanting of the most successful tree species and investigation into possible modifications to improve site hydrology.

Director Division of Water Quality Re: Senter Sand and Gravel Mine, 2005 Monitoring Report, Harnett County (DWQ# 96-1136) Dear Mr. Snyder: DWQ has received and reviewed your letter dated June 1, 2006 and the, "Senter Sand and Gravel Mine, 2005 Wetland Monitoring Report, April 2006." A few comments arose while the report was being reviewed. 1. The well monitoring locations and names are unclear due to some discrepancies in the report. The well table in Appendix #6 refers to wells A-1, 2, and 3 and wells B-1, 2, 3, and 4. The figure in Appendix #7 shows the presence of wells A-1, 2, 3, and 4 and wells E-1, 2, 3, and 4. Please verify which well situation is accurate and correct the necessary information in the report. 2. It is unclear what the numbers in the Appendix #6 well data table represent. Please provide the meaning of the positive and negative values located in the table. Negative values traditionally represent depths below the surface and positive values indicate inundation. This traditional meaning does not appear to correspond with the text description. Also verify that "Month 1 Week 1" corresponds to January 1-7. 3. Please provide a graph of the well data so that the depths and trends can be more easily seen. Also show the. ground` surface level and 12" below the surface on the graph for easy determination of the success criteria being met. 4. Please provide a larger image of Appendix #7 "Monitoring Line Location Map." The map received in our office is so small that the text, numbers, and boundaries are difficult to see. Please also show the location and direction of the Monitoring Transect Photographs on this map. 5. As you noted in the report, the vegetation did not meet the 320 trees per acre for 2005. DWQ agrees that a site visit may be needed to determine what corrective actions may need to b61.°°° Caro 'na tura?y 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://www.ncwaterquality.org An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper made to the vegetation and/or hydrology on the site to increase the woody vegetation on the site. 6.

Becker Minerals was originally issued a Nationwide Permit No. 26 (Action ID No.199701563) by the Department of Army, Corps of Engineers, Wilmington District Office on February 6, 1997 to be allowed to impact 5.93 acres wetlands above the headwater of an unnamed tributary of the Upper Little River at the Harnett Quarry near Lillington N.C. One of the conditions of permit issuance was that a mitigation plan be developed for off site mitigation, at a ratio of 1:1, at the Senter Mine which is located in the Upper Little River drainage basin near Lillington, N.C. (Appendix 7). Becker Minerals engaged Environmental Services, Inc. of Raleigh to develop the required mitigation plan. The mitigation plan was approved by the Department of Army, Corps of Engineers, Wilmington District Office on October 27, 1997. The approved mitigation plan requires that annual monitoring of the created wetlands be completed by October 1 of each year and a monitoring report be submitted by December 1 of each year. 2) Hydrology of the Mitigation Site: A requirement of the mitigation plan is to demonstrate that the created wetland area will have a typical wetland hydrology. The mitigation area contains a number of surface ponds that are connected to the ground water table. The surface area of the ponds changes during the year in response to storm water runoff from areas above the mitigation site. The yearly (2000 through 2005) rainfall measurement data obtained in the vicinity of the mitigation area are included in Appendix 5. Surface hydrology is demonstrated by the presence of the ponds. To demonstrate the presence of subsurface hydrology two sets of monitoring wells were installed within the mitigation area. A set of monitoring wells consists of three to four wells in a line across the mitigation area between the upland fingers (Appendix 7). One set of wells was installed at the northern end of the mitigation area (Wells A-1 through A-3) and the other set at the southern end of the mitigation area (Wells E-1 through E-4). Both sets of monitoring wells lie on a permanent monitoring transect. The monitoring wells were installed in accordance with the specifications provided by the Corps of Engineers. The monitoring wells were set to a depth of three feet below the surface. The monitoring wells have been read on a semimonthly basis. Well data, relative to the ground surface, are presented in Appendix 6. A value of zero represents water depth at the ground surface. Negative values equal depth below the surface, while positive values indicate inundation. Water levels in the monitoring wells were measured and recorded on 30 occasions throughout 2005. The wetland hydrology criterion consists of saturation within 12 inches of the surface exceeding 12.5 percent of the growing season, which equates to a minimum of 28 consecutive days in Harnett County based on a growing season of 226 days (March 23 through November 5). 3) Monitoring Transects Lines: A total of five permanent transect lines were initially established in the wetland area in 1998. The transect lines locations were selected to be representative of all conditions that are present in the mitigation area. The transect lines generally run from an upland across the wetland to the opposite upland. In 2000, two additional transect lines were added to be representative of the areas where seedlings were planted in February 2000 (Transects F and G). Since the monitoring has been completed for Transects A through E, this report presents monitoring data for Transects F and G, only. A map indicating the locations of the monitoring transects is given in Appendix 7. The beginning and end of each of the transect lines are marked with a pipe driven into the ground. A plastic marker is placed at 100 foot intervals along the transect line. Each tree within 20 feet of the centerline of the transect was surveyed and marked with pink ribbon to identify it as a tree to be monitored. Trees within the monitoring zone were identified by species, and the height and girth of the tree was measured and recorded. Dead trees were recorded but not measured. Table #1 summarizes the information recorded from each transect in 2005. Detailed tables of the tree monitoring results are given in Appendices 2 and 3. Photographs of the two transects appear in Appendix 8 and the approximate location and direction of each photograph is indicated on the Transect Location Map in Appendix 7. Appendix 9 contains photographs of other areas of the mitigation area that were taken on the same day. Table 1.

Girth of Trees in 0.3 0.3 % Survival of Trees 40.5 35.8 of Volunteer Trees 0.0 5.0 Live Planted Trees per Acre 250 280 4) Discussion of Monitoring Results: The average height of the trees in Transects F and G increased from 2004 to 2005, indicating continued growth of the seedlings (Appendix 4). The average girth of the trees in Transect G increased steadily from 2004 to 2005 while average girth in Transect F was unchanged. The 2005 percent survival was 40.5 for Transect F and 35.8 for Transect G. Only 63 and 51 percent of the trees recorded in 2004, for Transects F and G, respectively, survived until the end of the growing season in 2005 (Appendix 1). Although the remaining live trees continued to grow on Transects F and G, tree mortality for the two transects combined, was higher than that of any other monitoring year. Tree monitoring data can reflect the presence or absence of hydrology necessary to support hydrophytic vegetation throughout the wetland creation area. Precipitation and well data were examined to better understand the hydrologic conditions during 2005. Average annual rainfall for North Carolina for the period from 1995 to 2005 is 51.38 inches according to NOAA Climatic Data. Total average rainfall for North Carolina in 2005 was 50.27 inches. NOAA rainfall data for the years 2000 to 2005 show higher than normal rainfall in 2003; lower than average rainfall in 2000 and 2001 and slightly less than average rainfall in 2002, 2004 and 2005. Local rainfall data is collected at the Elliott Mine operation, approximately 3 miles away from the Senter Mine. Annual rainfall as recorded for 2005 was 39.4 inches, several inches below the state average and the lowest of any year recorded at the Elliott Mine (2000-2005) (Appendix 5). All of the seven wells indicated that wetland hydrology criterion of water table depth within 12 inches of the surface was being met, except for well E-4 (Appendix 6). None of the measurements taken during the growing season (March 23 - Nov 5) at E-4 showed water table depth within 12 inches of the surface. For the mitigation plan to be a success a survival rate of 320 trees per acre has to be met at the end of five years. This criterion was not met in 2005 (Table 1, Appendix 1). This is most likely attributed to the severe 2005 drought conditions present in this area, as indicated by the rainfall data, well data, and resulting tree mortality. 5) Conclusions The monitoring results for 2005 show that success criteria for the monitored wetland areas at the Senter Plant are not being met. As in the approved Senter Mine Mitigation Plan, coordination with the appropriate regulatory agencies will be undertaken to determine the most appropriate remedial action. This will mostly likely include replanting of the most successful tree species and investigation into possible modifications to improve site hydrology.
