Mallison, of 805 W 2nd Street, Washington, NC 27889 1 am submitting this statement expressing my concerns based on previous scientific studies and on my own 30 years' living here and fishing and boating in Blounts Creek and nearby Core Point. I am also expressing the concerns of Mrs. Georgia Little, a 50 -year resident of that area, whom I interviewed. I would like to submit an article by Fred Bonner, which appeared on page 9 in the March 2, 2013 Washington Daily News, and the following two studies by the U.S. Fish & Wildlife Service and the NC Dept. of Environment and Natural Resources, Division of Water Resources: (1) Copeland, B J, R.G. Hodson, and S.R Riggs. 1984. The Ecology of the Pamlico River, North Carolina: An Estuarine Profile. U.S. Fish & Wildlife Service. FWS /OBS- 82/06.83 pages (2) Lauber, Jeff C. August 2009. Hydrogeologic Framework and Ground Water Conditions in the North Carolina East Central Coastal Plain. NC Dept. of Environment and Natural Resources, Div. of Water Resources. 45 pages. www.ncwater.org /Reports and Publications /GWMS Reports /ECCP Framework eccpframe map report.php Mr. Bonner is a well respected outdoorsman whose columns appear regularly in the Washington Daily News. He titled his article, "Don't Mess with a Tar Heel's Fishing Hole" using plain speech deliberately. Mr. Bonner describes the fish and wildlife found in the Blounts Creek area and points out that it is noted not only for its freshwater fishes such as largemouth bass and bluegills, but also anadromous fishes such as herring, shad, striped bass, and speckled trout. He pinpoints many people's concerns with the Martin Marietta marl rock quarry. I quote him: "The problem that seems to be bothering a lot of people is that no one seems to know dust 1 exactly what the effect this waste water will have on the environment of Blounts Creek..." He further questions if the state might be attempting to push it through without in -depth study. I assert it cannot be proved that the proposed mine will not be harmful to the wetlands and estuary nursery system of which Blounts Creek is a part. I am referring to the Martin Marietta Materials, Inc. quarry proposing to be built near Vanceboro in Beaufort County. assert it is also difficult to do an in -depth scientific study to predict the result of this mine venture, i.e. to marshall the resources necessary to do such a study. If a sufficiently in- depth, focused scientific study on the areas affected cannot be done by the state agencies involved, then it becomes even more important that we should expand the concept of expert testimony to include field observations by knowledgeable local residents. At this time, I seriously doubt that the state agencies and their representatives —much less experts hired by Martin Marietta —can predict yes or no with any accuracy what will be the consequences of the planned discharge of waste water from the mine into Blounts Creek. I petition that DENR accept as evidence the observations and assessments of fishermen, hunters, local hunting and fishing guides, and residents of the area and other people whose business it is to observe conditions and water life in and around Blounts Creek and Blounts Bay and the Pamlico River, such as the Pamlico -Tar Riverkeeper Heather Deck I also assert that the common sense opinion of most who care is that the proposed discharge of waste water, its rate and volume and content, will have an impact and that impact will adversely affect water life because it will impact the balance within the estuary, that the point areas of proposed discharge are not divorced from the rest of the system. These people's observations and assertion should be respected who have witnessed the life that exist, there, in the complex interplay Mother Nature provides there from the interplay of pH, salinity, temperature, bottom conditions, winds, aeration and lack of it, the seasons, sunlight, plant life, depth of water. For example, people have seen what happens with sediment - loading after hurricanes (and sediment loading is also a concern if the mine goes forward); these people have seen what happens to the life of the estuary when different conditions are present, and have observed the rich variety of 2 transitory and migratory marine water life now existing in the areas now under discussion, especially the water life who are dependent on brackish water for part of their lives. How can even the subject of mitigation restitution and monetary value be broached if it is not known the long term harm that may be caused? Are there relevant, recent studies that include the status of the Pamlico River estuary system? I found only the Copeland study, which was completed in 1984 and covers the period between 1965 and the early 1980s. It examines the bottom organisms, migrating ocean fish, other important seafood, and the generally complicated, seasonal and shifting nature of this estuary system. The study involved systematic trawling of fish and net catch counts by commercial fishermen. While out of date, this study has the kind of depth and rigor that we need today to determine a baseline. Another serious concern is how this proposed mine would waste valuable drinking water from our Castle Hayne Aquifer. We in Beaufort County already have a cone of depression in the area created by the Potash Corp. mine, and some scientists have expressed the need to monitor the region to prevent the Aquifer from turning salty in the future. Ruined and scarce drinking water would be a severe economic loss and blow to people's wellbeing. Other nearby areas already treat and recycle their water or have to process salt water, while we still have a supply of cheap drinking water. Again, it is not possible to project the effect this proposed mine would have on the hydrology of our area without a reliable, recent baseline. I would like to point out that although Potash Corp. uses a huge amount of water from Castle Hayne, they reuse most of that water. Martin Marietta has said it is too expensive for them to treat or find a way for the water to be reused. I request you read the Lautier study on this subject. The Lauber study points out sites where the state is monitoring, but says there are problems because several of these testing sites are in poor repair and therefore can't produce accurate readings. Mr. Lautier concludes , "...this report identifies numerous places in the region where improvements are needed in the existing Division of Water Resources ground water monitoring network either due to improperly constructed wells, incomplete stations, or areas where additional stations are needed (p 42)." He states "Population growth in the NC Coastal Plain has led to increased reliance on ground water supply needs. This has fueled the need to understand in more detail, the system of aquifers and containing beds that underlie the region, and in particular how the aquifers are being affected by current pumping conditions. A better and more detailed understanding of the hydrogeologic framework will allow for development of strategies for dealing with water level declines in the confined aquifers of the Coastal Plain " (p 41). DENR and other agencies should accept common sense input from local residents as to whether this mine would prove to be, overall, a good or bad thing for the region. Without a reliable baseline the risks to marine life and our drinking water are inexcusable. My common sense tells me the Pamlico is already showing signs of distress, fishing has been declining for many years, but that Blounts Creek, Blounts Bay, and nearby portions of the Pamlico River are still relatively healthy and support a variety of marine and freshwater life, but this mine will adversely change and harm the delicate balance now existing. We are coming to a tipping point, and we might be looking at a dead river in a generation. We need to protect our assets The major asset of Beaufort County besides its people is the Pamlico River including Blounts Creek. The few lobs this mine would produce are not worth the long term destruction of all the other fobs that depend on the environment. Just considering the extra cost to taxpayers from all the heavy trucks this mine would put on our roads, whatever tax revenue the mine would produce seems like a wash. To quote John Hood from the John Locke Foundation on the March 3, 2013 NC SPIN, "Heavy trucks on our roads cost more than the taxes they pay." Common sense tells me this mine is a risky, bad deal.

Central Coastal Plai n of North Carol i na as covered i n this study i s made up of the ti dewater regi on between the A Ibemarle Sound and Onslow Bay I t i s referred to as a ti devater regi on because many of the rivers and streams are affected by ocearn c ti dal f I uctuati ons The study area i ncl udes Beaufort Washi ngton Tyrrel I Dare Hyde Pamlico Craven and Carteret Counties (figure i) This region has expert enced ever -i ncreasi ng reliance on ground water as a source of water supply resulting from population growth and tourism In addition open pit mi ni ng operati ons that requi re dewaten ng have also placed i ncreased stress on the ground water system For this reason it is important to understand in more detail the three dimensional framework of aquifers and confining units their hydraulic properties and how they are being affected by pumping stresses Moreover i t i s essenti al to understand the distribution of saltwater in the system and how it is bang affected by pumping The area covered in this study is situated within the tidewater region of the North Carol i na Coastal PI a n T he regi on has been descri bed by Stephenson and others (1912) and Nelson (1964) as a broad eastward di ppi ng plai n that encompasses one of a sen es of en echelon marine terraces which formed during the R a stocene era and were deposited in parallel orientation with the Atlantic Coastline Stephenson and others (1912) named it the Pamlico terrace as it is transected by the Pamlico River and Sound As indicated on the geologic map of North Carolina (Brown and others 1985) the western boundary of the terrace is an escarpment (Suffolk scarp) that runs north to south across the study area from the town of Plymouth i n Washington County to the town of Newport in Carteret County The western -most section of the study area extends a fav miles to the west of the Suffolk Scarp on an older marine terrace Land surface elevations across the region vary from sea level to 55 feet with the hi ghest elevations found in the western -most part although the dunes on the Outer Banks can exceed 50 feet above sea level The region i s generally of low relief and swampy A number of large natural lakes are present i ncl udi ng Phel ps M attamuskeet Pungo and N e%v L ekes T he Paml i co N euse Pungo and A I I i gator Ri vers di ssect the land surface al ong thei r courses to the A I bemarl e and Pamli co Sounds The geology of the East Central Coastal Rain maybe characterized as a gently southeastward di ppi ng and southeastward thi ckeni ng wedge of sedi ments and sedimentary rock ranging in age from Recent through Cretaceous (possibly Triassic) which rests on an underlying basement complex of Paleozoic age rocks The basement Hydrogeologic Frameavork and Ground aA ater Conditions in the East Central North CarolinaCoastal Plain April 2009 North Carolina Department o; Environment and Natural Resources Di v 19 on of ' Vater Resou rtes 7 of 57 3/11/2013 11 44 PM Microsoft Word ' TABLE 0F CONTENTS dou'l ECCPFramebody pdf bttp//wwwnuwatur CS Washington Dare Hyde Hydrogeologic FranneworkandGrnund'Ala&erCondhonsmtheEastCemtral || North Carolina Coastal Ran April 2009 North Carolina Department of, Environment and Natural Resources D/v/soncl NA'aterResooncew 8 of 57 3/11/2813 11 44PM Microsoft Word -

PREFACE This estuarine profile is one of a series at publications concerning current issues facing the Nation's estuaries_ its purpose is to synthesize existing informa- tion to describe the structure and func- tion of the Pamlico River Estuary, North Carol ina. The Pamlico River Estuary and its associated tributaries constitute the mos t important tributary to Pamlico Sound, which is the heart of North Carolina's vast coastal system. Pamlico Sound yields the majority of the commercial and recrea- tional fisheries catch taken in the State and serves as a base for a large and impor- tant recreation and tourism industry. It is also one of the most valuable coastal resources on the east coast of the United States. The profile is a state -of- the -art synthesis, bringing together available information on the Pamlico River Estuary, especially that critical to managing the estuary. In many instances, critical gaps exist in information needed to effect management. Where this occurs we have iden titied the gaps, suggested comparisons with similar estuarine systems in other sections of the country or world, and described ways that the missing informa- tion may be accommodated. Because the estuary is an intact in- tegrated unit, we are approaching the pro- file from a systems viewpoint. No one function or any particular component oper- ates in isolation from one another. Like - wise, the integrated estuary does not func- tion in isolation from the streams enter- ing it, the land around it, the estuaries and sounds connected to it, or the ocean adjacent to it. We have attempted in this iii http• / /www.nwrc.usgs gov /techrpt/82- 06.pd1 profile to describe the geological, bio- logical, chemical, and physical character- istics of the Pamlico River Estuary and then to spatially and temporally relate the components to illustrate the inte- grated estuarine system. Finally, in Chapter 6, we suggest a multi - faceted management strategy tempered by socio- economic realities and institutional constraints. The Pamlico River Estuary has re- ceived considerable attention during re- cent years. During the past decade, the overall fisheries catch has fluctuated, shrimp catch has declined, and nuisance algal blooms have caused fish kills and have reduced aesthetic values. Changing land uses, increasing industrial and resi- dential development, and freshwater diver- sions have been implicated. In response to some of these conflicts, the Governor appointed a multi - faceted Task Force in 1981 to examine water management problems in the area and to make recommendations for improvement. These recommendations were presented to the Governor in December 1982 and implementation has begun. Thts profile should be useful in assisting these important State efforts as well as assisting in the national perspective.

CHAPTER 1 iidTRODIlCTION --THE SETTING 1.I. PAMLICO RIVER ESTUARY AS A NATURAL UNIT ilne of the Mst important estuarine systems in Worth Carolina, the Pamlico River Estuary, is a continuation of the Tar River and extends from Washington, Borth Carolina, for about 65 km to its con- fluence with Pasmlito Sound (figure 1). The estuary is oriented approximately WNW - ESE ane gradually tapers from less than 0.5 km wide at its western limits eastward to over 8 kia wide at its mouth, where it grades into the very broad and shallow Pam- lico Souna (Luk ir. and Mauger 1983). The es teary extends to where the shoreline turqs northward out in the sound. The Tar River begins in the Piediiont and meanders across the Borth Carolina Coastal plain. The coastal plain is gen- er a l l y a broad surf ace that slopes gently seaward and is woJeratety dissected by the drainage oatterns of river systems (Brown et al. 97 ?). The incised streams with their associated floodplains and swamp forests, in combination with the upland interstream divides, produce the major top - ograpbiti relief; the relief decreases sea - ward as the coastal plain approaches sea level. The Tar River flows into and becomes the p&miico Rivpr Estuary jdst west of wasnington, N.C. 2The oblong basin drains about 14,000 Km , falls aPproxi- riately len0 m from its origin to sea level, and delivers relatively large volumes of fresh crater. Large loads of suspended clay sediments are carried to the coastal system via the Tar River. The upper half of the Tar River basin lies in the hilly Piedmont with a narrow floodplain, w1iile the lower nalf has develooed a broad floodplain as it flows across the low, flat coastal plain. The Persil ico itiver Estuary, which is generally perpendicular to the ocean shorPlIne, is the flaoied portion of the far River basin ai:r: its extensive floodplain. Numerous lateral tributaries drain off the low, flat, swampy coastal area http• / /www.awrc usgs.gov /tccbrpt/82- 06.pdf into the main Pamlico River Estuary. These streams have considerably smaller drainage basins with low relief and small discharges of fairly acid blackwater. Con- sequently, the sediment load is low and dominated by organic matter derived from. the broad floodplain swamp forests and upland pocosins. Lateral streams flaring directly into the westerrmiost portion of the estuary include Blount$, Tranters, and Broad Creeks. farther downstream in the central and eastern portions of the Pamlico River Estuary, trig lateral streams have been flooded to form small lateral sub - estuaries such as Pungo River, North Creek, Durham Creek, Goose Creek, South Creek, and Bath CreeK. The Pamlico River Estuary ar_tl the Neuse River Estuary to the south are the major freshwater tributaries to Pamico Sound, which dominates the North Carolina coastal area (Figure 1). Thus, the estu- ary is bounded on the crest by the Tar River, on the north by the AlbemarTe- PamilTco peninsula, on the east by PMlico Sound, and on the South by the Pamlico -Meuse peninsula. The Pamlico River Estuary is not direct iy connected to the ocean, but is a tributary to the expansive Pamlico Sound (Giese et al. IY /9;. Consequently, there is no direct exchange with the ocean and lunar tidal amplitude is very low. There is a large freshwater inflow relative to tidal volume, and biological communities are subject to drastic hydrographic flue- tuations during weather extremes. 1.2. GEOLOGICAL ORIGIN AND EVOLUTIOtt Sediments and sedimentary rocks of marine origin underlie the entire Pam ico River Estuary region (Brown et al. 1972). These sediments were deposited on top of the same type of crystalline rocks that occur In the Piedmont and were deposited when the ocean covered portions -of the 16 of 99 3/9/2013 1143 AN Figure 49. Map of Pamlico Sound, showing primary nursery areas (Copeland et al. 1983). primary nursery areas (Weinstein 1979; Hodson et al. 1981). Unlike the croaker, young spot are found in great densities in shallow marsh areas irrespective of tidal effects throughout their range (Chao and Musick 1977; Weinstein_1979; Miller and Dunn 1980). 4.3. SPATIAL - TEMPORAL RELATIONSHIPS A combination of tributary inflows and water - temperature changes character - i_ze.- the-seasons in the Pamlico River Estu- ary- (1Cuenzler et al. 1979). Highest tribu- tary faf,lows occur during January through April_ (see: Section 2.5). Consequently, during_ the, -late winter and early spring, wihen- freshwater runoff peaks, the estuary receives -nutrients, detritus, and other materials from upland drainage. These are important­to -the system. As the water be- gins -to -warm ifi- the spring and solar radia- tion, inCreases, phytoplankton productiv- ity increises_(Figure_50). This increase in primary - productivity-is _quickly fol- lowed by an increase ip - zooplankton produc- tion. High springtime - productivity_ coin- cides with the recruitment of postlarval fishes and shellfish -and support`s the postlarvae populations that enter the estuary during that time to use the nur- sery grounds (Section 4.2)- One of the characteristic adapata- tions of organisms to the seasonality existing in temperate estuarine systems is that of seasonal migrations (Copeland et al. 1974a). This adaptation permits the rapid proliferation and growth of animal populations during the optimal season of food production and energy availability. At Rose Bay, a tributary nursery area off the Pamlico River Estuary, Miller and Currin (1982) found that the consumption rate of juvenile spot and croaker in- creased dramatically during late March and April (Figure 51), when the biomass of benthos in that area peaked. Migrating stocks of animals become part of the estu- arine energy cycle, became integrated into the functioning ecosystem, and then emi- grate to another system. In this way estuaries like the Pamlico River Estuary along the coast are interconnected through the migrating energy and biomass cou- plings. This pattern of resource utiliza- tion among functional groups of fishes maximizes the ecological efficiency of the estuary. The timing of the combination of physical and biological activities of the Table 23.

The model compart- ments (Q's) and the primary phosphorus concentrations (averaged over all sampling times and stations) are given in Table 14. Twenty different pathways of phosphorus movement (J's) among compartments were distinguished and are tabulated in Table � 5. Measurements were not made of the zooplankton, nekton, and benthos processes, and they are excluded from the model. Two forcing functions, light intensity (1) and temperature (T), impact the rates ( X ) of uptake and the level of biological functions, and are shown at the appropriate junctions in the model. The exact rates and impacts on rates are not known: therefore_ these oathways are The efflux of phosphorus from the phytoplankton (Q ) and bacterial (Q ) compartments baci to inorganic reactiG phosphorus (Pathways JS and J , respectively) is also 14rl3i ( Table. Phosphomonoesterase activity (J ) is thought to be negligible. All othP ath- ways are small and difficult to measure (Kuenzler et al. 1979). Thus, the major aspects of phosphorus cycling in the estu- ary are the uptake and release of reac- tive phosphorus by phytoplankton and bac- teria. This substantiates the observa- tion that the major source of phosphorus for primary productivity is through recy- cling in the estuary rather than inputs from the watershed.

Transects for macrobenthic sampling in the Pamlico River Estuary (Tenore 1970). The diversity and density of macro - benthos was relatively low (Tenore 1970). This was attributed to shifting sediments in large portions of the estuary, absence of tidal flats due to the low tidal flux, changing salinity regimes; and the annual occurrence of conditions leading to anoxic sediment conditions. The seasonal ranges of distribution and density of the domi- nant macrobenthic species to the shallow estuary, due to the anoxic conditions there during the summer. Thus, the bulk of the benthic productivity in the Pamlico River Estuary is in sediments under water less than 1.5 m deep. Unfortunately, data on actual production rates are still lacking for this estuary. An analysis of the macrobenthic samples indicated that the estuary could be divided into three community types ( Tenore 1970) . This analysis was accom- plished with the aid of a trellis diagram (McFayden 1963) , whereby an index of af- fin7ty (Sanders 1960) was calculated for the fauna from each depth section of each strata during each season (Tenore 1970). This index of affinity was defined as the percentage of fauna common to a pair of samples. The analysis was completed by comparing the index of affinity for all possible combinations of sample pairs. An index value was determined for each pair by summing the smaller of two percentages of species present in any two samples (e.g., when sample 1M, which has 40% spe- cies a, 20% species b and 40% species r_ is romoarPd to Sample B. which has I WWW,; AM1LVNEWS£At4 - _ SAT Saw Wad*AgftN round fas sDbcMed °us from ii-but. - Said % -ifuW years that; UMMOILI, ingr Of Odr ooagtal ) <- �. the - , infhe buikwss of oubfioar- ; - bi de= Aw- re&& ion.
