HUNTLEY Administrative Assistant ELLEN DOSSER-County Engineer letter of March 30, 1993, Per your request, I am amending my explaining the procedure used to measure the water level in the monitoring wells at the proposed'"landfill. If, when the weight was dropped into the monitoring well, we could not hear the water, a small stone or pebble was thrown into the well. If we still could not hear the water, and the weight was not visibly wet, we assumed the well was dry or that the water level was at the bottom of the well. If we did hear the water splash, we dropped the weight into the well again until we could get a measurement. As you will note at the top of the data sheets, it is noted that these readings are approximate and this will be taken into consideration by the state in their review of the landfill design. The county has since purchased a water level indicator, which will be used to determine purging volumes, during sampling,'at our existing landfill and to determine the water levels at the proposed landfill. The next measurements will be taken in May. should you need any additional information or if I can be of further assistance do not hesitate to contact this office. Sincerely, LAI?`?'l? GZ?yp,SL9??V?

Natural erosion occurs on a geologic time scale, but the process can be greatly accelerated when human activities alter the landscape. The sediment produced by erosion generally winds up in the surface waters. Some of the activities that increase sediment loads to waterbodies include: construction activities, unpaved private access roads,' state road construction, golf courses, uncontrolled urban runoff, mining, timber harvesting, agriculture, and livestock operations. Some of the adverse impacts of sediment include: • StrPambank erosion: Streams with high sediment load have a much greater potential to scour the streambank. Also, as the streambed fills in with sediment, the stream will widen to carry the flow. Streambank erosion causes the loss of valuable property. • Damaged aquatic communities: Sediment damages aquatic life by destroying stream habitat, clogging gills, and reducing water clarity. • Polluted water: Sediment often carries other pollutants with it, including nutrients, bacteria, and toxic/synthetic chemicals. This pollution can also threaten public health if drinking water sources and fish tissue become contaminated. • Increased costs for treating drinking water: Sedimented waters require costly filtration to make them suitable for drinking. Water supply reservoirs lose storage capacity when they become filled with sediment, necessitating expensive dredging efforts. Programs and best management practices aimed at addressing sedimentation are briefly described in Chapter 5. General recommendations to reduce sedimentation are listed in Chapter 6, Section 6.5. North Carolina does not have a numeric water quality standard for suspended sediment. However all point source dischargers must at a minimum meet federal effluent guidelines (e.g. 30 mg/l for domestic dischargers) for total suspended solids (TSS). The biochemical oxygen demand (BOD) limits required for most point sources usually necessitate a degree of treatment that assures the removal of solids to a level below federal requirements. A TSS limit of 10 mg/1 is required for discharges to those High Quality Waters (HQW) which are trout waters or primary nursery areas, and a limit of 20 mg/l is required for discharges to other HQWs. North Carolina has adopted a numerical instream turbidity (measurement of water clarity) standard as follows: • 50 Nephelometric Turbidity Units (NTU) in streams not designated as trout waters; • 25 NTU in lakes and reservoirs not designated as trout waters; • 10 IVTU in trout waters. Land disturbing activities are considered to be in compliance with the standard if approved best management practices have been implemented. E ets of Sedimentation Sedimentation is often divided into two categories: suspended load and bed load. Suspended load is composed of small particles that remain in suspension in the water. Bed load is composed of 3-2 Chapter _3 - Causes of Impairment and Sources of Water Pollution over a whole watershed or county or state area and thereby give the impression that the problem is less significant than it actually is in the immediate area. It makes much more sense from a management perspective to target sediment reduction in a high impact area from 40 tons/acre to 2 tons/acres, rather than reduce erosion from cropland in general from 6.5 to 6.3 tons/acre. This points to the need for targeted management efforts coupled with a monitoring strategy which effectively measures sediment transport under both average and extreme conditions. Table 3.3 USLE Erosion on Cultivated Cropland in North Carolina 1982 1987 1992 Cropland land Area (1,000 acres) 6,318.7 5956.8 5538.0 Gross Erosion (1,000 tons/ r) 40,921.4 37475.3 30,908.3 Erosion Rate (Tons/Yr/Ac) 6.5 6.3 5.6 While there is an overall 10-year downward trend statewide in the erosion rate on agricultural lands, the erosion rate per acre and the 10-year trends vary by region as shown in Table 3.4. The greatest decline in erosion is seen in the Southern Piedmont and Sand Hills with a small uptrend in the tidewater area and a significant increase in the mountains. In the mountain region, it is noted that while the 10-year trend is up, the five-year trend from 1987 to 1992 was down. The reasons for the dramatic changes in the mountain basin erosion rates are not fully known.

These include the Ararat River, Fourth Creek, Brushy Fork, Hamby Creek, Brown Creek, Coddle Creek, Goose Creek Richardson Creek, Lanes Creek, Hitchcock Creek and North Fork Jones Creek. The water quality of many other streams in the basin is threatened by sedimentation and erosion. The following discussion on erosion, sediment loads, USGS gaging station data and sediment fate and transport relates specifically to the Yadkin-Pee Dee River basin. Suggested general management strategies for reducing sedimentation are presented in Chapter 6, Section 6.5. Historic Rates in the Basin In 1979 the USDA conducted an erosion and sediment inventory for the entire Yadkin-Pee Dee basin. While the results of this inventory do not necessarily reflect erosion rates in the mid-1990s, they do provide us with a picture of historical conditions. Based on 1978 land use data, the USDA study estimated erosion from agricultural and urban areas, as well as other sources. As shown in Table 3.5, erosion rates ranged from 5.6 tons/acre per year in Yadkin County to 1.5 tons/acre per year in Montgomery County. Erosion rates were considerably higher for subbasins and counties in the upper portion of the basin than for most areas in the lower basin.

Of the nine sampling events, two were oligotrophic, five were mesotrophic, and two were eutrophic. Lake Bunch was most recently sampled on August 23, 1994. The lake was oligotrophic and fully supporting its designated uses. Back Creek Lake (Lake Lucas) Back Creek Lake (also called Lake Lucas) is the primary water supply for the City of Asheboro. The reservoir is part of a public park where fishing, boating, and swimming are common. Hypolimnetic aerators have been installed near the water intake structure to improve the quality of the water before it is withdrawn for treatment. The watershed is drained by Back Creek and Greenes Branch. Approximately half of the drainage area is wooded and the rest is cultivated. Back Creek Lake was sampled by DWQ on July 27, 1989. The concentration of iron was greater than the state water quality standard of 1 mg/l. Chlorophyll a was greater than the state water quality standard of 40 µg/1 at the upstream and mid-lake sampling sites (58 and 81 µg/1, respectively). Back Creek Lake was sampled on August 23, 1994. Back Creek Lake fully supports its uses. Lake Reese The City of Asheboro impounded the Uwharrie River and Caraway Creek to form Lake Reese, a water supply also used for recreation. Farms and residential areas exist in the drainage area and bordering the lake shore near the upper end of the lake. Lake Reese is only used after the primary water supply (Back Creek Lake) has a three-foot drop in level. The lake was sampled by DWQ on August 7, 1989 and all parameters were within acceptable ranges. On August, 25, 1994, Lake Reese was again monitored. Lake Reese was borderline eutrophic and fully supporting its uses. Aquatic Toxicity Monitoring One facility in this subbasin currently monitors effluent toxicity as per a permit requirement. That facility is Furniture Illustrators, Inc. 4.3.10 Pee Dee River from Lake Tillery Dam to Blewett Falls (Subbasin 03-07-10) Description This subbasin consists of the portion of the Pee Dee River and its tributaries (with the exception of the Little River in subbasin 03-07-15) from the Rocky River confluence to the dam at Blewett Falls Lake (Figure 4.33). Although the subbasin is located entirely in the piedmont ecoregion of the state, Brown Creek (the largest tributary to the Pee Dee in this subbasin) and many of its tributaries have coastal plain characteristics and very little flow during the summer. In contrast, Mountain Creek and its tributaries have good flow during the summer and are located in hilly topography more typical of the piedmont. Land use in this subbasin is primarily a combination of forest and agriculture. The town of Wadesboro is the largest urban area. This subbasin contains 8 permitted dischargers all of which are small (<0.5 MGD). Overview Of Water Quality There are currently two ambient monitoring stations located in this subbasin: Brown Creek at SR 1627 near Pinkerton, and the Pee Dee River at NC 109 near Mangum. Elevated levels of manganese and iron were observed at both locations and are indicative of nonpoint runoff. Four macroinvertebrate samples have been collected in subbasin 10 since 1983. Sampling was conducted at Brown and Mountain Creeks in 1996. A sample collected on Brown Creek received a Fair bioclassification, most likely due to the effects of nonpoint runoff and reduced flows during the summer. Mountain Creek, which generally has good flow during the summer, received an 4-52 Chapter 4 - Water Quality in the Yadkin-Pee Dee River Basin Excellent bioclassification. Prior special studies produced a Good-Fair rating for Lick Creek in the upper portion of the Brown Creek drainage and a Poor rating for Savannah Creek. No flow was observed at either site during 1996 investigations. Fish community assessments were performed at 3 sites during 1996. NCIBI ratings ranged from Fair-Good at Cedar Creek to Good-Excellent at Mountain Creek. Fish community ratings in upper Brown Creek and lower Cedar Creek indicated effects from siltation, habitat degradation, and nutrient enrichment. Mountain Creek was one of only six streams in the Yadkin basin with an NCIBI rating of Good-Excellent. Fish tissue samples were collected at Blewett Falls Lake during 1996. Sixteen samples composed of bass, crappie and catfish were analyzed for metals contaminants. Mercury levels exceeding FDA and EPA criteria were detected in one catfish sample. Potential HOW/ORW Streams The macroinvertebrate and fish data collected from Mountain Creek at SR 1150 indicated Excellent water quality for the stream. Based on this information, the Mountain Creek catchment could be resampled, if petitioned, to determine if the stream warrants reclassification to HQW/ORW. Lakes Assessment Program B,?wett Falls Lake Blewett Falls Lake is a run-of-the-river impoundment. Land use is mostly forested, with some agriculture and a small amount of urban development. As is true of the other Chain Lakes in North Carolina, Blewett Falls Lake receives the majority of its inflow from the discharge of the upstream reservoir, Lake Tillery. See Section 4.2.3 for more characteristics of the lake. Blewett Falls Lake was one of 16 North Carolina lakes assessed in 1973 for the National Eutrophication Survey (USEPA, 1975). Survey data indicated that the reservoir was eutrophic. However, because of the short retention time (approximately seven days), Blewett Falls Lake more closely resembled a slow-moving, over-enriched river. Blewett Falls Lake was previously sampled in 1981 through 1986. During this period, the reservoir was predominantly eutrophic. In 1981, percent oxygen saturation (182.9%) was greater than the state water quality standard of 110% for dissolved gases. The chlorophyll a value of 43 µg/1 was greater than the state water quality standard of 40 µg/1. In 1982, chlorophyll a (40 µg/1) was at the state water quality standard limit for this parameter and the lake was hypereutrophic. In 1983 the lake showed a dramatic change to mesotrbphic conditions. Blewett Falls Lake was most recently sampled by DWQ on July 26, 1994. The lake was eutrophic but fully supporting its uses. Aquatic Toxicity Monitoring One facility in this subbasin currently monitors effluent toxicity as per a permit requirement. That facility is Ellerbe WWTP, which had one test failure in both 1995 and 1996. 4.3.11 Upper Rocky River and Coddle Creek (Subbasin 03-07-11) Description in Cabarrus This subbasin includes the uppermost reach of the Rocky River watershed, primarily County (Figure 4.34). This reach runs approximately 25 river miles from its headwaters near Mooresville to its confluence with Irish Buffalo Creek. This subbasin contains the urban areas of Mooresville and Concord. Coddle Creek, a large tributary of the Rocky River, and. many of its smaller tributaries are classified as water supply (WS-II). All other tributaries and the entire Rocky River in this subbasin have been given a C water use classification. 4-54 7 w M Q) CA f3 W L a y Q y a G .yi f3 a C Q f F a ?L GL C1 Z Z Z ?I Z ?

R e co rnm.e n cla tt nn,s: Observations from regional office personnel indicate that Clarks Creek has low flow during dry periods. Considering the limited flow available for the assimilation of wastewater, it is recommended that further evaluation and updated flow information from USGS be obtained if the discharge remains, or new discharges locate to this creek. J. Uwharri.e River Watershed (Subbasin 03-07-09) This subbasin consists of the Uwharrie River and its tributaries. Monitored lakes include McCrary Lake, Lake Bunch, Back Creek Lake and Lake Reese. This subbasin has no impaired waters, although considerable sedimentation is evident on the upper portion of the watershed and many of these waters are support threatened (Refer to Chapter 4, Section 4.5). Problems in these headwaters are attributed to land use and urbanization. Caraway ('reek (Support Threatened) The largest discharger, Countryside MHP, has a permit to discharge 0.015 MGD into a UT to Caraway Creek, a class WS-I11 stream. The UT has an estimated 7Q10 and 30Q2 flow equal to zero. Occasional instream DO violations, as low as 4.6 mg/l, have been reported by the facility during the period 1994-1996. Recomm.enclations: If no practical alternatives to discharge are available, it is recommended that Countryside MHP's wasteload allocation be modified to advanced tertiary limits for oxygen-consuming wastes under current zero flow procedures. K. Pee Dee River from Lake Tillery Dam to Blewett Falls Dam (Subbasin 03-07-10) This subbasin includes the Pee Dee River and its tributaries from the Lake Tillery dam to the Blewett Falls Lake dam, with the exception of the Rocky River (subbasins 03-07-11 to 03-07-14) and the Little River (subbasin 03-07-15). The largest tributaries in this subbasin are Brown Creek and Mountain Creek. The Pee Dee River and Brown Creek are impaired waters (Refer to Chapter 4, Section 4.5). Pee Dee River below Lake Tillery (Partially Supporting) levels. The cause of the The Pee Dee River below Le O levels as to Tillery is imaired due related to to low es s disc,l arge from CP&L's hydroelectric substandard D PPear facility on Lake Tillery. Recommendations: DWQ, in coordination with the NC Division of Water Resources, will explore mitigative actions to correct this problem when the facility comes up for FERC relicensing in 2008. In addition, new or expanding discharges to the Pee Dee River in this subbasin should meet limits no less stringent than 15 mg/1 BOD5, 4 mgA NH3-N, and 5 mg/l DO. Additional activities and resources are needed to identify impairment sources and to develop management strategies for this waterbody. As resources allow, DWQ intends to develop NPS management strategies for this waterbody for the second Yadkin-Pee Dee River Basin Plan (refer to Section 6.3.3). In addition, local efforts are needed to develop a plan to reduce nonpoint source pollution for the Pee Dee River. 6-21 Chapter 6 - Water Quality Concerns and Recommended Managenurnt Strategies Brown Creek (Partially Supporting) Brown Creek, the largest tributary in this subbasin, is susceptible to low flow during dry summer conditions. Although there are no permitted dischargers in its drainage area, Brown Creek received a Fair bioclassification rating in 1996. Low instream DO concentrations have been reported at the ambient station at SR 1627 near Pinkerton. Water quality appears to be negatively affected by a combination of low stream flow during dry periods and nonpoint source pollution during wetter periods. Sedimentation is also a probable cause of impairment. Recommendations: It is recommended that no new discharges be permitted in the Brown Creek watershed. In addition, additional activities and resources are needed to identify impairment sources and to develop management strategies for this waterbody. As resources allow, DWQ intends to develop NPS management strategies for this waterbody for the second Yadkin-Pee Dee River Basin Plan (refer to Section 6.3.3). In addition, local efforts are needed to develop a plan to reduce nonpoint source pollution for this creek. L. Upper Rocky River and Coddle Creek Watersheds (Subbasin 03-07-11) This subbasin includes the headwaters of the Rocky River to above its confluence with Irish Buffalo Creek. Coddle Creek is the major tributary. Most of the waters in this subbasin are Support Threatened (Refer to Chapter 4, Section 4.5). The Rocky River and Coddle Creek are impaired waters. Dye .Branch and the headwaters of the Rocky River are significantlyunpacted by Mooresville's discharge, which has had frequent toxicity failures. In 1993, DWQ completed a field-calibrated dissolved oxygen model for 47.6 stream miles of the upper Rocky River area in subbasins 03-07- 11 and 03-07-12, from its headwaters to the confluence with Muddy Creek (NCDEM, 1993b). The modeled area includes portions of Dye Branch and Mallard Creek, as well as the Rocky River mainstem. The model was developed to evaluate the assimilative capacity of the river and to assess the interaction between three major dischargers: Mooresville (into Dye Branch), the Charlotte- Mecklenburg Utilities District's Mallard Creek WWTP and the Rocky River Regional WWTP (in subbasin 03-07-12) operated by Cabar-us County. Fecal coliform bacteria levels and sedimentation are also problem parameters in the Rocky River. Recomm.enda zions: Model results indicate that Mallard Creek and the Rocky River upstream of Mallard Creek have limited assimilative capacity and that new or expanding dischargers, if permitted, should receive BAT limits (5 mg/I BOD and 2 mg/l NH3N). This recommendation may affect both the Mooresville and the CMUD-Mallard Creek W WTPs. Model results also indicate that Mooresville's permitted limits for oxygen-consuming wastes are predicted to result in violations of the DO standard in the Rocky River. However, during 1994-1996 Mooresville, on average, treated its wastewater to well below its permitted limits and no DO violations were reported by the facility during this period. The DO standard appears to be protected at Mooresville's current level of treatment and waste flow. However, should the facility wish to expand in the future, DWQ will review the limits and make modifications where they are appropriate and justifiable. Model results indicate that there is remaining assimilative capacity in the Rocky River below Mallard Creek. New or expanding discharges are likely to receive total BODu limits of approximately 32 mg/l (BODS and ammonia limits will vary depending upon effluent characteristics). The model will be used to evaluate specific scenarios for the future allocation of oxygen-consuming wastes in the upper and middle reaches of the Rocky River. 7..d M 0 0 0 r L r M 6-22 Chapter 6 - Water Quality Concerns and Recommended Management Strategies Table 6.1.5 Recommended TMDLs and Management Strategies for Addressing Oxygen- Consuming Wastes with Reference to Subbasin Summaries.

Rain And Floods Hit This Section Heavily Farmers and Others Sustain Severe Losses in Last Week's Wet Weath- er and High Water-Other Section; Are Hit Harder. Since the heavy rains and destruc- tive freshets of the first of last week, people of Anson county and other sections have been busy checking up on their losses. While thousands of dollars in dam- age to roads and bridges cannot he disregarded, the loss to farmers and stock raisers is the worst feature )f the flood in this "county. Experts of the various agricultural organizations have been at wort: in an effort to calculate the , darnaL,:e, but no official figures have yet been tabulated. In response to an inc?iiry, County Farm Arent J. W. Cameron told The M. & I. yesterday that the agricul- tural damage is so great that it is not estimable. He went on to say: . "All crops on lowlands are pra(-ti-• call,y a total loss. Corn on the up- lands is damaged very, badly due to the fact that -the ears were heavy, the•.,ground was soft after so much rain, and hence there is more corn on the ground than we have ever seen: before. "I think a conservative estimate of. the damage to upland corn would be around 20 percent, and I would say the damage to upland cotton would be lip to 20 percent-and in many in- stance-, more. Lesnedeza is badly damaged, clue tai the fact that it wa:; )down over and much of it will i)e hard to harvest either for Ceed or for hay.;,A great,, deal will either mold,:or rot cn account of bedding down. Grazing also is badly damaged, due to overflowing leaving much mud on the grass to make it unpalatable and not. so good for livestock. "1 would like to say again that the damatre is great and inestimable. as it is they worst flood we have h'ra? t)einges Sweep Countri. From this summ:try, it Call be seen tivit Anson county hits lost hundreds of thousands of dollars in its current crops; alone. No accurate money val-. ue (-.in be set, in. fact, until the final crop reports are made next, spring. A; stated in this newspaper last week, several head of livestock were drowned and swept away in the swol- len creeks and rivers. Even yet, the stock growers have not fini,hed checking their herein to be sure of their standing. Added to the farm loses, the county must ri ure the damage to public and industrial installation::. The 'Caroli•na Power & Liahtt'Co., with its. flooded . Blewett Falls , lant, and t'he other public utilities-will add thousands of dollars to the high-wa- ter bill, with reconstruction S>.r.-re'7a- bilitation of their properties. The working time loss figures no small item. The Seaboard 'Railway had its. main line' through Wadesboro blocked from Tuesday through to Friday at noon. As a result, no mail or express could be handled through usual channels. Readers of The M. & L in many places failed to receive their newspapers until two days later than usual. far one example. In :another field, the large mills driven by electricity in this area lost consid- ejable. time while the power systems were being readjustd. While the large hi?_,hways have been made passable, ttiere are sev- eral broken places in country roads which must have rebuilding Jobs done before vehic6s can travel freely. Some time will elapse before large bridges, such as the Rocky river, Lanes creek and Brown creek strue- tures. can be replaced. Here, again, no defInite estimate of the cost is yet available. ova E CHARLOTTE OBSERVER ..:'V JOHN 0.
