PCS Phosphate Amendment Review Subject: PCS Phosphate Amendment Review Date: Fri, 13 Jul 2001 16:07:00 -0400 From: "Chris Fidalgo" <chris.fldalgo@ncmail.net> To: <tracy.davis@ncmail.net> CC: "Felix Fong" <felix.fong@ncmail.net>, "Mel Fry" <Mel.Fry@ncmaii.net> Tracy - Alf of the involved parties at DRIP have reviewed the mining amendment permit request from PCS phosphate and found it to be acceptable. If you need a formal statement on this, let me know. Keep in touch, Chris Fidalgo NC Division of Radiation Protection 1 of 1 7/16/2001 9:52 AM 'North Carolina Department of Environment and Natural Resources Division of Radiation Protection Michael F. Easley Governor William G. Ross Jr. Secretary Richard M. Fry Director June 7, 2001 John Carrere, Environmental Scientist Environmental Affairs PCS Phosphate - Aurora P.O. Box 48 1530 NC Highway 306 South Aurora, NC 27806 Dear Mr. Carrere: In NCDENR This letter is being written to summarize our recommendations for the disposal of scrap metal contaminated with Naturally Occurring Radioactive Material (NORM), in this case primarily Radium- 226, at the PCS Phosphate - Aurora site. These recommendations were presented at a meeting conducted at the Division office in Raleigh on April 25, 2001, which was attended by representatives from DRP, the Division of Land Resources, and PCS Phosphate. Please see Attachment 1 for a copy of the presentation from this meeting and Attachment 2 for an event chronology for this issue. Several consensus determinations were reached in this meeting. The first of these is that the disposal of this material would be handled in regulatory terms by your company applying to the Division of Land Resources for an amendment to the PCS Phosphate mining permit. The material in question can be considered "mining refuse" and therefore can be exempted from solid waste regulations if disposed of onsite. The second determination reached after a presentation of the results of a risk analysis by DRP personnel of onsite disposal is that the health threat posed by this disposal is minimal. This same conclusion was reached for both onsite workers and members of the public using the most conservative assumptions and valid site -specific data. The final major determination was made concerning the method for disposal of material. DRP personnel agreed to provide a formal written procedure based on the determinations reached in the April 25 meeting. This procedure includes the following: The material will be disposed of onsite in the remains of Gyp Stack #2. Gyp Stack #2 is currently being torn down and used for land reclamation. When this process is complete, a layer of gypsum material approximately 20 feet thick will remain. See attached engineering diagrams (Attachments 3 & 4) for details. The material will be disposed of in two separate areas in the gyp stack: one area for all material accumulated up to this point and another area for disposal of material in the future. 2. A portion of Gyp Stack #2 will be excavated to provide an area for disposal of the existing material. A bottom layer of gypsum material with a minimum thickness of four feet (4) will be left after this excavation. 3. The NORM -contaminated material will then be placed in the excavated disposal area. This layer should be as thin as practical, and care in placement should be taken to avoid creation of voids in the 1645 Mail Service Center Raleigh, North Carolina 27699-1645 Phone: (919) 571-4141 FAX: (919) 571-4148 Internet: www.drp.enr.state.nc.us AN EQUAL OPPORTUNITY 1 AFFIRMATIVE ACTION EMPLOYER - 50% RECYCLED 1 10% POST CONSUMER PAPER `Mr. Carrere Page 2 disposal cell. By compacting the disposal cell in this way, the potential for settlement in the area should be reduced. 4. Once all of the material has been placed in the disposal area, the area should be filled in level with the top of the gyp stack with gypsum material. This top layer should have a minimum thickness of four (4) feet. At a later date, the gyp stack will be stabilized with a cover layer of eighteen (18) inches of topsoil and vegetation in accordance with the PCS Phosphate mining permit. 5. A detailed description of the disposal method and an accompanying map of the disposal area will be prepared by a land surveyor and/or onsite engineering staff that indicates the following: The top and bottom elevations of the NORM -contaminated material. The top and bottom elevations of the gyp stack in the disposal area. The coordinates (latitude and longitude) of each corner and the distances between corners of the disposal area. 6. Copies of this final description of the above work and accompanying map will be submitted to the Division of Radiation Protection and Division of Land Resources for review and comment. Another copy should be kept by PCS Phosphate's Engineering or Planning office as part of the facility permanent record. A determination was also reached in the April 25 meeting concerning the question of disposal of similar material in the future. PCS Phosphate indicated that future material would be buried in a manner similar to the procedure discussed above, but in a separate area in Gyp Stack #2. This future disposal area would be in the area of the gyp stack reserved for gypsum sales (for agricultural purposes, etc.). It is our understanding that the volume of any future disposal of material will be small in comparison to the amount of material accumulated to date. Any disposal of material in this area would have to be carried out in accordance with the procedure outlined above, as would be specified on the amended PCS Phosphate mining permit. In addition to the requirements Iisted in the above procedure, any future material designated for disposal should first be scanned for external radiation levels subject to the following conditions: The scans will be conducted by qualified personnel, i.e., the PCS Phosphate - Aurora Radiation Safety Officer, or his/her designee. 2. The material will be scanned in a low background area - 34 µ Ir or less, ambient gamma. 3. This radiation level scan will be done with a properly calibrated instrument capable of detecting gamma radiation in the µR/hr range, such as a Ludlum Model 19 or Model 12 microR meter. 4. All items designated for disposal will be scanned at one -meter distance and at surface contact. If the material is in some sort of container, such as a 55-gallon drum, the contact scan can be performed on the outer surface of the container so long as the container does not contain substantial voids and is the final disposal vessel. Mr. Carrere Page 3 5. If the final uncorrected readings exceed 500 µR/hr at one -meter distance or 5000 µR/hr on contact, PCS Phosphate will need to notify both the Division of Radiation Protection and the Division of Land Resources prior to burial. If all radiation readings are below these limits, PCS Phosphate can dispose of the material without contacting DRP or DLR, provided it is in accordance with the approved mining permit. The information contained in this letter should be incorporated into your mining permit amendment request to the Division of Land Resources. We will be glad to work with the Division of Land Resources to review your amendment request if they so desire. Please advise us when your amendment request has been approved and when the tentative dates for commencement and completion of the disposal activity have been scheduled. In conclusion, I believe that any solution to this problem should have three goals: 1) To minimize exposure to the public and PCS employees, 2) To keep this material from being recycled, 3) To have a permanent record of the location of the disposal location should retrieval of the buried material be required in the future. Because of the lack of regulation of NORM in North Carolina, a collaborative effort is required to solve the problems associated with NORM material disposal. I look forward to working with you on this issue in the future.

E dt . '%► March 21, 2001 Mr. Christopher J. Fidalgo North Carolina Department of Environment and Natural Resources Division of Radiation Protection 1645 Mail Service Center Raleigh, NC 27699-1645 Dear Mr. Fidalgo: Per your March 13, 2001 request one "filter pan" was removed from the top of the Number Two Gypsum Stack, placed in an area of relatively low background, and a radiological survey of the filter pan conducted. Enclosed for your review is a table summarizing the gamma photon radiation field data obtained as both a surface contact reading and as a 1-Meter reading. A drawing of the filter pan surveyed is enclosed to show the relative points on the filter pan from which the surface contact and 1-Meter readings were obtained. Previous experience with surveying materials contaminated with Radium-226 has shown that the radiation field readings obtained with the Sodium Iodide scintillation crystal used in the Ludlum Model 12 S Micro R Meter must be corrected to reflect the energy dependent response error for the Radium-226. Reported values from the March 16, 2001 filter pan survey reflect a correction factor of 1.65 without any correction for the cosmic or terrestrial background found in the survey area. To assist those unfamiliar with phosphate mining and manufacturing of phosphoric acid, I have briefly outlined below the phosphoric acid manufacturing process in terms of how the naturally occurring radioactive material present in the phosphate ore contaminates the process equipment. Phosphate ore is mined at the PCS Phosphate Aurora Facility and used in the manufacturing of phosphoric acid. Radionuclides present in the phosphate ore are Uranium-238, approximately 20 to 40 ppm, Thorium-230, and Radium-226, all of which are naturally occurring radioactive elements. The Uranium-238 decays to Radium-226 and eventually to stable Lead-206. In the manufacturing of phosphoric acid by the wet process phosphate ore is mixed with sulphuric acid. The resulting chemical reaction between the ore and acid produces phosphoric acid and gypsum [calcium sulphate]. The phosphoric acid is separated from the gypsum by filtering the slurry through a pan type or belt type of filter. During the slurry filtration process the Uranium, most of which will be dissolved in the phosphoric acid solution, will go with the phosphoric acid solution while the Radium-226 will go with the gypsum by-product produced. During the acidulation process that takes place in the phosphoric acid plants attack tanks the Radium-226 ion behaves chemically similar to a calcium ion and during the chemical reaction forms a Radium Sulphate precipitate that will deposit on the surface of the process equipment and piping as "scale." Although the amount of Radium-226 in the phosphate ore that is available to be precipitated as a scale is small, over time, the process equipment in contact with the acid and gypsum will become contaminated with the radioactive scale due to the volume of acid and gypsum that passes over and/or through the process equipment. Process equipment contaminated with radioactivity above background levels cannot be disposed of through the normal metal recycling outlets. Scrap metal and other process materials from the phosphoric acid plants are surveyed for radiation levels above background to prevent contaminated process equipment from leaving the facility accidentally. Over time the amount of contaminated material has accumulated and it was recommended that the contaminated process equipment be re- located to a central area at this facility. The PCS Environmental Affairs Department has requested permission from the State Division of Radiation Protection to dispose of the contaminated process materials by burying them in the Number Two Gypsum Stack which will continue to be used for agricultural gypsum sales to farmers. The phosphate ore contains Radium-226 which leaves the process with the gypsum. Several years ago the EPA imposed restrictions on the Radium-226 content of gypsum that was sold for land application. Since 1992 the Environmental Affairs Department has sampled the gypsum sold annually. Analysis of the gypsum for Radiurn-226 content indicates that the average concentration of Radium-226 in the gypsum can varied from a low of approximately 4 pCi/g to a high of approximately 11.3 pCi/g. Although not involved in the original discussions with the State Division of Radiation Protection it is my impression that during the original discussions only disposal of the filter pans had been requested. There are other materials such as stainless steel piping, steel and plastic piping, valves, pump impellors and pump casings, sections of metal troughs, and bricks from tank linings just to name a few of the items that have the potential to be contaminated with Radium-226 scale and should be buried in the gypsum stack as they cannot be allowed to enter the recycled metal waste streams. It is my understanding from the Environmental Affairs Department that whenever contaminated process materials would be placed onto the gypsum pile for disposal they will be covered with a layer of gypsum. At some future date the final elevation of the gypsum stack surface would be covered with a layer of topsoil and some type of vegetation planted to prevent future surface erosion. .0 • ot The gypsum stack contains small amounts of Radium-226which upon decay will produce Radon-222 gas. Because of the potential radon hazard this area will be a controlled access site essentially forever. Should the State allow the contaminated process materials to be buried in the gypsum pile it would be relatively easy to verify that the external radiation hazard to the public from the buried materials in the gypsum stack should not be any greater than the current external radiation hazard produced by the Radium-226 present in the gypsum that was used to bury the contaminated process equipment. If you have any questions pertaining to the survey data please feel free to contact me at 252-322-8118. Gerald J.

Davis, P.E. <Tracy.Davis&ncmail.net> State Mining Specialist Division of Land Resources NC Dept. of Environment and Natural Resources 2 of 2 4/20/2001 5:26 PM March 21, 2001 Mr. Christopher J. Fidalgo North Carolina Department of Environment and Natural Resources Division of Radiation Protection 1645 Mail Service Center Raleigh, NC 27699-1645 Dear Mr. Fidalgo: Per your March 13, 2001 request one "filter pan" was removed from the top of the Number Two Gypsum Stack, placed in an area of relatively low background, and a radiological survey of the filter pan conducted. Enclosed for your review is a table summarizing the gamma photon radiation field data obtained as both a surface contact reading and as a 1-Meter reading. A drawing of the filter pan surveyed is enclosed to show the relative points on the filter pan from which the surface contact and 1-Meter readings were obtained. Previous experience with surveying materials contaminated with Radium-226 has shown that the radiation field readings obtained with the Sodium Iodide scintillation crystal used in the Ludlum Model 12 S Micro R Meter must be corrected to reflect the energy dependent response error for the Radium-226. Reported values from the March 16, 2001 filter pan survey reflect a correction factor of 1.65 without any correction for the cosmic or terrestrial background found in the survey area. To assist those unfamiliar with phosphate mining and manufacturing of phosphoric acid, I have briefly outlined below the phosphoric acid manufacturing process in terms of how the naturally occurring radioactive material present in the phosphate ore contaminates the process equipment. Phosphate ore is mined at the PCS Phosphate Aurora Facility and used in the manufacturing of phosphoric acid. Radionuclides present in the phosphate ore are Uranium-238, approximately 20 to 40 ppm, Thorium-230, and Radium-226, all of which are naturally occurring radioactive elements. The Uranium-238 decays to Radium-226 and eventually to stable Lead-206. In the manufacturing of phosphoric acid by the wet process phosphate ore is mixed with sulphuric acid. The resulting chemical reaction between the ore and acid produces phosphoric acid and gypsum [calcium sulphate]. The phosphoric acid is separated from the gypsum by filtering the slurry through a pan type or belt type of filter. During the slurry filtration process the Uranium, most of which will be dissolved in the phosphoric acid solution, will go with the phosphoric acid solution while the Radium-226 will go with the gypsum by-product produced. During the acidulation process that takes place in the phosphoric acid plants attack tanks the Radium-226 ion behaves chemically similar to a calcium ion and during the chemical reaction forms a Radium Sulphate precipitate that will deposit on the surface of the process equipment and piping as "scale." Although the amount of Radium-226 in the phosphate ore that is available to be precipitated as a scale is small, over time, the process equipment in contact with the acid and gypsum will become contaminated with the radioactive scale due to the volume of acid and gypsum that passes over and/or through the process equipment. Process equipment contaminated with radioactivity above background levels cannot be disposed of through the normal metal recycling outlets. Scrap metal and other process materials from the phosphoric acid plants are surveyed for radiation levels above background to prevent contaminated process equipment from Ieaving the facility accidentally. Over time the amount of contaminated material has accumulated and it was recommended that the contaminated process equipment be re- located to a central area at this facility. The PCS Environmental Affairs Department has requested permission from the State Division of Radiation Protection to dispose of the contaminated process materials by burying them in the Number Two Gypsum Stack which will continue to be used for agricultural gypsum sales to farmers. The phosphate ore contains Radium-226 which leaves the process with the gypsum. Several years ago the EPA imposed restrictions on the Radium-226 content of gypsum that was sold for land application. Since 1992 the Environmental Affairs Department has sampled the gypsum sold armually. Analysis of the gypsum for Radium-226 content indicates that the average concentration of Radium-226 in the gypsum can varied from a low of approximately 4 pCi/g to a high of approximately 11.3 pCi/g. Although not involved in the original discussions with the State Division of Radiation Protection it is my impression that during the original discussions only disposal of the filter pans had been requested. There are other materials such as stainless steel piping, steel and plastic piping, valves, pump impellors and pump casings, sections of metal troughs, and bricks from tank linings just to name a few of the items that have the potential to be contaminated with Radium-226 scale and should be buried in the gypsum stack as they cannot be allowed to enter the recycled metal waste streams. It is my understanding from the Environmental Affairs Department that whenever contaminated process materials would be placed onto the gypsum pile for disposal they will be covered with a layer of gypsum. At some future date the final elevation of the gypsum stack surface would be covered with a layer of topsoil and some type of vegetation planted to prevent future surface erosion. The gypsum stack contains small amounts of Radium-226which upon decay will produce Radon-222 gas. Because of the potential radon hazard this area will be a controlled access site essentially forever. Should the State allow the contaminated process materials to be buried in the gypsum pile it would be relatively easy to verify that the external radiation hazard to the public from the buried materials in the gypsum stack should not be any greater than the current external radiation hazard produced by the Radium-226 present in the gypsum that was used to bury the contaminated process equipment. If you have any questions pertaining to the survey data please feel free to contact me at 252-322-8118. Gerald J.

Jeff Furness of PCS (the person we deal with regarding the mining permit) called me yesterday and we discussed this situation as well. He indicated that you and one of his counterparts have been discussing this and developing a disposal plan for this material. I gave Jeff (and Floyd Williams, our regional engineer) a heads up on how we handled a similar situation at the Chematall site in Kings Mountain. Jeff said he was going to let you and his counterpart work out a plan that is acceptable to you, then Jeff would submit it to me as a formal mining permit modification request. During the review of this request, it would be routed to you for formal review and comment (so you can confirm that it addresses all of your concerns). I will be out of the office 4/9--4/13, in a civil penalty appeal hearing on 4/17, in the Wilmington region on 4/24, in a meeting most of the day on 4/26, and in a high profile permit revocation hearing 4/30-5/2. Thus, there are only a limited number of days I could attend an onsite meeting. However, as the specifications on the permanent disposal of this type of material comes from your shop (like the Chematall site) and we generally accept what you do, it is not imperative that I am present during this site visit. I am familiar with the site and, if needed, could do a site inspection during the formal review process. My recommendation is that you set up a meeting that best suits you and your contact with PCS and, if Floyd Williams and I can make it, we'll be there ... if not, you can go without us so as not to hold up the project. Let me know what you think. Thanks again for your assistance with this project.

We can back DCM up with Mining Permit conditions as appropriate. At the same time, I'm sensitive to the fact that once the phosphate ore underneath these creek -heads is passed by the mining progression, it is forever lost to societal benefit. I know you (we) have to balance that loss against the wetlands/nurseries values, not an easy task. Thanks again, Charles Donna Moffitt wrote: The results of the April 17 field trip to the mine site and the April 18 scoping meeting were positive. PCS Phosphate told the attending regulatory staff that it would try to design its mining plan and permit requests to avoid mining in public trust waters. That should reduce the wetlands impacts also, which were originally some 92 acres. We will continue to work with the company to try to get a mining plan that reduces wetland impacts to the greatest extent possible. If there are still wetland impacts in the final permit application, we will have to deny the CAMA permit for failure to meet the CRC's use standards and then the company would have to seek a variance from the CRC. According to my staff, the last permitting and environmental review process took about 10 years so this could be a long term effort. I'll attempt to keep you informed only on major points in the process. Donna Moffitt wrote: FYI on phosphate mining in the creeks in Beaufort County. Obviously, this is going to be a HOT issue. Since we are leaning towards requesting that the company put the SEPA document preparation on hold until and unless the company gets a mining permit and/or an easement from State Property, you might get the first official requested action in DENR, Charles.

PCS is proposing to mine several creeks and tributaries (Huddles Cut, Huddy Gut, Tooleys Creek, Drink Water Creek, Jacobs Creek and Jacks Creek. Huddy Gut is considered Estuarine Waters while the remaining are Public Trust Waters and Inland Primary Nursery Areas. It is our understanding that PCS does not have any mining rights underneath any of these creeks. As such, the question has been raised whether we (or the Company) should spend a whole lot of time and resources on the scoping, preparation, review, etc. of an EIS when they don't apparently have any vested right or permission from the state to dam these public waters and resources and to mine public trust bottoms. David is going to be attending a meeting next week with PCS to discuss this project. one item on the agenda is a discussion of Public Trust Waters/state owned bottom. I would ask him to provide us with a summary of that discussion. If, in fact, they don't have any lease or mining rights to these areas, I feel it would be appropriate for them to first cross that hurtle with the State before we and the other agencies devote a lot of time and energy to the EIS process. (As you well might guess, the project will be controversial and the environmental issues will be huge. If the State declines to issue them mining rights for the creeks, that part of the project would be a dead issue.)

As you will note, one of the items to be discussed on the second day is the issue of mining public trust areas. It is our understanding from PCS that they do not own any rights to the creeks they propose to mine. My question is, how can we go forward with an EIS process without a clear understanding from the State as to the DOA stand on this issue?

We fe Parch is not responsible for reimbursing Mr. Wiley's pump expense incurred on approximately 1, 2001. The hydrographs for our Bath and Lee Creek stations (see attached graph) indicate little to no static water level change around the time Mr. Wiley was having pump problems. DWR feels that the problem of low pressure that Mr. Wiley is experiencing is due to problems in the house plumbing. There have been numerous fluctuations in the water levels in the past 17 years and Mr. Wiley never noticed low water pressure before. Nat and I have called Mr. Wiley to discuss our conclusions on this matter. PCS was correct in replacing Mr. Clemmons" surface pump with a jet pump due to noticeable water level declines observed at our Bath and Lee Creek stations. However, based on recent problems described by Mr. Clemmons, PCS needs to investigate and correct any problems between the pump and the well.

Application information was received on December 17, 1999 (under cover letter dated December 10, 1999) and on June 14, 2000 (under cover letter dated June 9, 2000). I am recommending issuance of an Approval to Construct for the R--7 Blend Dike, but offer the following: 1. It is recommended that Sheet 1 of 3 have a north arrow. 2. Could you send our office two copies of a sheet showing all the existing tailings dikes (along with the planned future dikes that are known at this time) just for general reference? This would be very much appreciated. (Some of us "old timers" are pretty familiar with the existing dike locations, but such a drawing or map would assist newer staff members to become more quickly familiar with the PCS Phosphate layout. I hope to include having Mr. Scott Harrell, E. I. and Mr. Bob Daniel, P. E., the two Assistant State Dam Safety Engineers attend the next environmental/permitting meeting at PCS Phosphate so that you and the PCS Phosphate staff can meet Scott and Bob.) 3. Each of the Cross Sections on Sheet 2 of 3 and on four of the cross sections on Sheet 3 of 3 have a note reading "Blend Surface El. +5", It is unclear what this means. Please clarify. (Page 13 of the Geotechnical Report indicates that 5 feet of freeboard is to be maintained at all times, and this may be the intent, but I am nor sure. It might not be a bad idea to indicate on the plans the maximum tailings elevation in the pond on the cross sections.) 4. Sheet 3 of 3, Weep Drain Detail at 3/1 Slopes, Plan View and Cross Section: (a) On the cross section, please reflect on the construction drawings and on the "as -built" drawings the height of the six-inch diameter drain outlet pipe above the base of the dike. (The Geotechnical Report (Page 2) suggests that it be located about one foot above the dike base.) (b) It is recommended that solid (not perforated) pipe be used for the outlet section of the drain pipes located 200 feet on center from the perforated collector pipe. (Using solid outlet pipe makes it much easier to observe the quality and quantity of seepage coming from the drainage system during routine inspections of the dam.) (c) It is recommended that end caps be used at the ends of the six-inch diameter perforated collector pipes to prevent dike material from entering the pipe at these locations. It is also recommended that 1 of 3 8/23/2000 4:48 PM PCS Phosphate R-7 Blend mike, Heaufort County animal guards be placed at the exits of the solid outlet pipes to prevent animals from entering and obstructing them. (d) For the perforated pipe, please indicate the desired hole size and the number of holes per lineal foot. If holes are only to be located on one side of the pipe, you may wish to indicate in specifications or in a detail or note on the plans that the side with holes be placed down to improve drain performance. (e) The drawings refer to use of a "sock filter" for the perforated pipe. (The specifications refer to wrapping the collector pipe with a non -woven filter fabric.) Please provide a specification for the filter fabric to be used on the construction drawings or in the specifications (and reflect on the "as -built" drawings). Please also specify the minimum overlap for wrapping of the pipe. 5. Specifications for Construction of R-7 Dike: (a) Decant Structures (Page 6) - Two decant structures are shown on the plans. This specification refers to details which were not included in the application. Please provide two copies of the details on the proposed decant structures and associated outlet works. (This will assist our filing system so that we do not have to refer to another file for drawings applicable to this dike.) (b) Piezometers (Page 6) - Please indicate on the plan sheets the locations and depths of piezometers that will be installed in the dike sections. It is requested that a standard detail be provided for their installation and table be located on the plans showing the top elevation, tip elevation, and screen length for each piezometer. (Also, see Geotechnical Report, Section 5.3.) (c) Miscellaneous (Page 7) - It is recommended that the applicable plan sheets indicate the locations where drain tiles are to be removed. (Also, see Section 1.3.1, "Section A" and Section 5.4 in the Geotechnical Report.) If all locations of the agricultural drain tiles are not known at this time, this information can be reflected on the "as -built" drawings. 6. An emergency action plan (EAP) and an operation and maintenance (O&M) schedule are required for all high hazard structures. You may wish to contact the local Division of Emergency Management for assistance in developing the EAP. The O&M schedule should address routine inspection, maintenance, and frequency of piezometer readings. These items may be submitted after an approval to construct is issued, but they must be received prior to issuance of an approval to impound. 7. 1 would appreciate your opinion, and that of your geotechnical consulting engineer whether it would be useful to have any settlement gage devices installed and the monitoring of such settlement gages. This may provide information that could be used in the design of future blend dikes. 8. In 'the design report, one PCSTABL5 plot titled "R-7 Dikes, Highwall Downstream 3:1, Steady State, With Toe Drain" dated 10-14-99 and time 8:14 a.m. indicates a particular phreatic surface. A second plot with the same title and date, but indicating a run time of 8:20 a.m. indicates a depressed phreatic surface and a higher factor of safety. It is unclear why the phreatic surface was depressed so far upstream in this second plot and its applicability to the analysis. 2 of 3 W23/2000 4:48 PM ti PC Phosphate R-7 Blend Dike, Beaufort County our office can provide you with an EAP form that is likely applicable for this structure. I will send you a copy of the EAP form. Please contact Scott Harrell, Bob Daniel or me after you receive the EAP form, and we'll be happy to discuss this with you.

A date certain has not been set. I've asked Jim Gulick to see if the ALJ will tie down the date this early, but they usually wait until about two weeks prior to the hearing to set the day(s) for the hearing. I suggest you let Jeff know that we can not all make a firm committment at this time for March 26. We'll have a better picture of the court calendar at least by mid --March, so you could hold a tentative date of March 26 for now for PCS and advise Jeff that we may need to reschedule it (if leaving it loose for now is okay with him).

In order for us to address similar unforeseen circumstances in the future when we might not have enough neutralization capacity in our clay stream, we request approval to add agricultural limestone in the blend circuit on an as -needed basis. If this approval needs to take the form of a modification to Mine Permit 7-1, we request that it be included with our currently pending modification request for erosion and sediment control facilities at our "trailer city" mine entrance site.

Robinson Location Aurora Subject Limest e Addition Trial As per your e-mail dated November 21, 2000, 1 am providing the results of the trial with the addition of limestone to the blend tank. The test was started on December 11, 2000 and concluded on December 18, 2000. Based on the analysis completed during this trial, the limestone addition to the blend tank provided an improvement in the pH of the material exiting the blend tank. The limestone material proved to be easy to handle and posed no dust problem. During the trial, approximately 552 tons of limestone was added to the blend tank over the 7-day trial period. This resulted in an average addition rate of 78.8 tons per day versus the 75 tons per day target. Due to variations in rate of gypsum and clay going to the blend tank it was difficult to look at any one value to determine the effectiveness of the limestone. Comparison of the data a week prior to the trial and the week after the trial to the data during the trial indicated an increase of 0.56 pH units. There were fewer low pH extreme values during the trial than in periods before or after the trial. Peak pH values were higher during the test than during the other periods. Before the trial began, handling of the material was a concern for us. We experienced none of the anticipated problems with handling the material. The Off Spec Ag Lime material was moist enough that it was not a dust problem yet not so wet it posed a handling problem. In fact, the material handled better than the clay due to the lack of large rocks and it stuck less to the backhoe bucket. The cost of material used for this one -week trial was $13,035.24 including delivery. This did not include the cost of the backhoe that was already in place for the Yorktown clay addition. Limestone addition could be increased to possibly 150 tons per day and maintain the clay addition at 60 tons per hour. Increases above that would require other measures or reduction in supplemental clay addition. I recommend we seek permission from the NC Division of Land Resources to use Limestone on an as needed basis to supplement the clay addition to the blend tank. cc: W. T. Cooper D. J. Millman T. L.

The site is located in Richland Township, ' Beaufort County, North Carolina, and north west of the point where the old and new alignments for NC Hwy 306 intersect. A system of ditches comprise the existing drainage and sedimentation control measures. These ditches are connected by culverts and discharge at various locations into surrounding wooded areas. Discharge sheet flows through the wooded ' areas into adjacent wetlands and the headwaters of Whitehurst Creek. The proposed improvements include the excavation of two ponds that will serve as the forebay and main storage pond for the site, a connecting culvert and discharge culverts, the excavation of a new ditch and the cleaning and regrading of ' two existing ditches that will discharge into the forebay. Existing ditches along the west and south sides of the site will remain undisturbed I except for the main pond discharge culverts installation. SITE DESCRIPTION ' Trailer City is a mining activity support site populated with trailers that serve many purposes. The site is relatively flat and is currently sloped so that runoff is ' directed to a ditch at the proposed forebay site. Existing surfaces are primarily gravel, with asphalt pavement, grassed surfaces and wooded areas also existing. PCS Phosphate Company, Inc. 3 2000192SEC 1 Fl, 1 1 L 1 SCOPE OF THE WORK 1 1. Verify the presence and location or absence of all underground utilities within ' the construction area, including, but not limited to those indicated in the accompanying drawings. ' 2. Clean out the existing ditch located north of the entrance road, at the entrance gate, and the existing culvert under the road to re-establish flow to the ditch south of the road. 3. Clean and regrade (as necessary) the existing ditch located south of the road and along the south east side of the site to establish flow toward the proposed forebay. t4. Remove the existing culverts located in the south east corner that discharge to the east and south. -- ' S. Excavate the proposed forebay and main pond bodies. Remove the spoil to an appropriate discharge site. 1 6. Install the riser and culvert assemblies in the forebay and main pond. ' 7. Excavate a new ditch along the north and north east sides of the site. 8. Install a culvert to connect the new ditch with the existing ditch north of the entrance toad and raise the grade of the driveway above the new culvert to provide a minimum of 12 inches of cover above the top of the pipe. ' 9. Regrade, as needed, the areas immediately surrounding the new excavations and cleaned ditches so that runoff can sheet flow into them. ' 10. Stabilize pond d and ditch side slopes with permanent vegetative cover. References: 1. Drainage Control Plan (Sheet 1 of 3) ' 2. Drainage Control Details (Sheet 2 of 3) 3.

Rip rap outlet protection shall be installed at outlets of culverts connecting the forebay and main pond, and the main pond discharges. 3. Side slopes shall be stabilized using permanent vegetative cover. CONSTRUCTION SPECIFICATIONS New risers and culverts shall be corrugated galvanized steel or corrugated aluminum with welded seams and re -rolled ends. Joan sections using standard band connectors. 2. Ponds, ditches, risers and culverts shall be dimensioned as indicated in the plans and details. 3. Install new culverts at elevations and grade indicated in the plans and details. 4. Install DOT Class 11 rip rap erosion protection at culvert outlets. 5. Compact backfill soil in 6 inch lifts along side culverts and in 12 inch lifts above culverts. Regrade surfaces above culverts as needed to provide a minimum of 12 inches of cover where vehicular traffic will cross over the culverts. ' 6. Permanent vegetative cover shall meet NCDENR Permanent Seeding standard 6.11. 11 DESIGN CRITERIA The proposed ponds were sized to meet NCDENR Stormwater SA/DA ratio standards for 3.5 feet deep permanent pools in coastal areas. A temporary pool depth of one foot (above the permanent pool) provides sufficient volume to retain the runoff created by a 1 inch rainfall onto the approximately 12.25 acre drainage area, as required by NCDENR. Riser and culvert diameters are designed to flow the runoff volumes calculated using the Rational Method, assuming a 10 year frequency, 60 minute duration rainfall intensity of 3 inches per hour. The orifices installed in the main pond outlets are sized to decant the 1 inch rainfall volume in approximately 3.5 days.

Purpose To reduce erosion and decrease sediment yield from disturbed areas, and to per- manently stabilize such areas in a manner that is economical, adapts to site con- ditions, and allows selection of the most appropriate plant materials. Conditions Where Fine -graded areas on which permanent, ion - livedvegetative cove r is the most Practice Applies practical or most effective method of stabilizing the soil. Permanent seeding may also be used on rough -graded areas that will not be brought to final grade for a year or more. Areas to be stabilized with permanent vegetation must be seeded or planted within 30 working days or 120 calendar days after final grade is reached, unless temporary stabilization is applied. ' Planning Vegetation controls erosion by protecting bare soil surfaces from raindrop im- Considerations pact and by reducing the velocity and volume of overland flow. ' The most common and economical means of stabilizing disturber) soils is by seeding grasses and legumes. The advantages of seeding over other means of establishing plants include the smaller initial cosr, lower labor input, and greater flexibility of method The disadvantages of seeding include: • potential for erosion during the establishment stage, ' the need to reseed areas that fail to establish, • seasonal limitations on suitable seeding dates, and ' a need for water and appropriate temperatures during germination and early growth. The probability of successful plant establishment can be maximized through good planning, knowledge of the soil characteristics (Table 6.1 la), selection of suitable plant materials for the site, good seedbed preparation, adequate timing and fertilization, and timely planting and maintenance. tSELECTING PLANT MATERIALS Climate, soils, and topography are the major factors affecting the suitability of plants for a particular site. All three of these factors vary widely across North ' Carolina, with the most significant contrasts occurring among the three major physiographic regions of the state--i'vlountains, Piedmont, and Coastal Plain ' (Figure 6.1 la). To simplify plant selection, a K to Permanent Seeding Mixtures Key g es is presented in Table 6.1 lb. To find seeding specifications for a specific site, follow this key through different the steps —region, slope, soil, and maintenance level —to the appropriate seeding number. Seeding mixtures recommended here are designed for general use and are well proven in practical field situations (Tables 6.1 lc 1 )'.I 1.i 1 1 L� T Table 6.11 a Suitability of Soli for Establishment of Low -maintenance Vegetation Criteria Suitability Limiting Factors Good Fair Poor pH 5.6-T8 4.5-5,5 <4.5 Too acid; possible Al, Mn, Fe toxicity Available >.10 .05-.10 <.05 Too dry water capacity.

They are designed to produce maximum stabilization and min- imize the amount of maintenance and repair required. Land use is a primary consideration in planning permanent seedings. For this purpose land use, whether residential, industrial, commercial, or recreational, can be divided into two general categories- High- maintenance areas are mowed frequently, limed and fertilized regularly, and either (1) receive intense use (e.g., athletic fields) or (2) re- quire maintenance to an aesthetic standard (e.g., home lawns). Grasses used for these situations are long-lived perennials that form a tight sod and are fine -leaved and attractive in appearance. They must be well - adapted to the geographic area where they are planted and able to endure the stress of frequent mowing. Sites where high -maintenance vegetative cover is desirable include homes, industrial parks, schools, churches, and recreational areas. Low -maintenance areas are mowed infrequently or not at all, and do not receive lime and fertilizer on a regular basis. Plants must persist with lit- tle maintenance over long periods of time. Grass and legume mixtures are favored for these sites because legumes are a source of soil nitrogen. Mixed stands are also more resistant to adverse conditions. Sites suitable for low -maintenance vegetation include steep slopes, stream or channel banks, some commercial properties, and "utility" turf areas such as road - banks. SEEDBED PREPARATION The soil on a disturbed site must be amended to provide an optimum environ- ment for seed germination and seedling growth. The surface soil must be loose enough for water infiltration and root penetration. The pH (acidity or alkalinity) of the soil must be such that it is not toxic and nutrients are available --prefera- bly between 6.0 and 6.5. Sufficient nutrients —added as fertilizer —must be present. It is as important to add lime as to add fertilizer. Lime is used primarily as a pH, or acidity, modifier, but it also supplies calcium and magnesium, which are im- portant plant nutrients. By increasing soil pH it also makes other nutrients more available to plants. At the same time, it prevents aluminum toxicity by decreas- ing the solubility of soil aluminum. Many soils in North Carolina are high in aluminum, which stunts plant growth. ,ALfter seed is in place, it must be protected with a mulch to hold moisture and modify temperature extremes, while preventing erosion during seedling estab- lishment. STEEP SLOPES The operation of equipment is restricted on slopes steeper than 3:1, severely limiting the quality of the seedbed that can be prepared. The soil cannot be suf- ficiently worked, and amendments cannot be thoroughly incorporated. Provisions for establishment of vegetation on steep slopes can be made during ' final grading. In construction of pill slopes, for example, the last4-6 inches might be left uncompacted. A loose, rough seedbed is essential. Large clods and stones II provide irregularities that hold seeds and fertilizer. Cut slopes should be, rough- ened (Practice 6,03, Surface Roughening). ' Where steepness prohibits the use of farm machinery, seeding methods are limited to broadcast or hydroseeding, with hydroseeding giving the most de- pendable results. Vegetation chosen for these slopes must not require mowing or other intensive maintenance. Using a hydraulic seeder, seed, fertilizer, wood ' fiber mulch, and a tacking agent can be applied in one operation. ' Good mulching practices are critical to protect against erosion on steep slopes. When using straw, anchor with netting or asphalt. On slopes steeper than 2:1, jute, excelsior, or synthetic matting may be required to protect the slope. ' Specifications SEEDBED REQUIREMENTS Establishment of vegetation should not be attempted on sites that are unsuitable ' due to inappropriate soil texture (Table 6.11a), poor drainage, concentrated overland flow, or steepness of slope until measures have been taken to correct these problems. To maintain a good stand of vegetation, the soil must meet certain minimum re- quirements as a growth medium. The existing soil should have these criteria, • Enough fine-grained (silt and clay) material to maintain adequate mois- ture and nutrient supply (available water capacity of at least .05 inches water to 1 inch of soil). • Sufficient pore space to permit root penetration. ' Sufficient depth of soil to provide an adequate root zone. The depth to rock or impermeable Iayers such as hardpans should be 12 inches or more, ' except on slopes steeper than 2:1 where the addition of soil is not feasible. • A favorable pH range for plant growth, usually 6.0-6.5. • Freedom from large roots, branches, stones, large clods of earth, or trash ' of any kind. CIods and stones may be left on slopes steeper than 3:1 if they are to be hydroseeded. ' If any of the above criteria are not met--i.e., if the existing soil is too coarse, dense, shallow or acidic to foster vegetation —special amendments are required. The soil conditioners described below may be benefciai or, preferably, topsoil may be applied in accordance with Practice 6,04, Topsoiling. SOIL CONDITIONERS In order to improve the structure or drainage characteristics of a sail, the fol- lowing materials may be added. These amendments should only be necessary where soils have limitations. that make them poor for plant growth or for fine turf establishment (see Chapter 3. Vegetative Considerations). ' Peat —Appropriate types are sphagnum moss peat, hypnum moss peat, reed - sedge peat, orpeat humus, all from fresh -water sources. Peat should be shredded and conditioned in storage piles for at least 6 months after excavation. Sand —clean and free of toxic materials. 1 ' 6.13..4 1 1 11 Practice Standards and Specifications Vermiculite —horticultural grade and free of toxic substances. Rotted manure ---stable or cattle manure not containing undue amounts of straw or other bedding materials. Thoroughly rotted sawdust —free of stones and debris. Add 6 lb of nitrogen to each cubic yard. Sludge —Treated sewage and industrial sludges are available in various forms; these should be used only in accordance with local, State, and Federal regula- tions. SPECIES SELECTION Use the Key to Permanent Seeding Mixtures (Table 6.1lb) to select the most appropriate seeding mixture based on the general site and maintenance factors. A listing of species, including scientific names and characteristics, is given in Appendix 8.02. SEEDBED PREP,�LRATION Install necessary mechanical erosion and sedimentation control practices before seeding, and complete grading according to the approved plan. Lime and fertilizer needs should be determined by soil tests. Soil testing is per- formed free of charge by the North Carolina Department of Agriculture soil [est- ing laboratory. Directions, sample cartons, and information sheets are available through county Agricultural Extension offices or from NCDA. Because the NCDA soil testing lab requires 1-6 weeks for sample turn -around, sampling must be planned well in advance of final garading. Testing is also done by com- mercial laboratories. When soil tests are not available, follow rates suggested on the individual specification sheet for the seeding mix chosen (Tables 6.11c through 6.11v). Application rates usually fall into the following ranges: Ground agricultural limestone: Light -textured, sandy soils: 1-1 1/2 tons/acre Heavy -textured, clayey soils: 2-3 tons/acre Fertilizer: Grasses: 800-1200 lb/acre of 10-10-10 (or the equivalent) Grass -legume mixtures: 800-1200 lb/acre of 5-10-10 (or the equivalent) Apply lime and fertilizer evenly and incorporate into the [opt inches of soil by disking or other suitable means.

Seedings properly carried out within the "best" dates have a high probability of success. It is also possible to have satisfactory establishment when seeding outside these dates. However, as you deviate from them, the probability of failure increases rapidly. Seeding on the last date shown under "possible" may reduce chances of success by 30-50%. Always take this into account in scheduling land -disturbing activities. Use certified seed for permanent seeding whenever possible. Certified seed is inspected by the North Carolina Crop Improvement Association. It meets Published North Carolina S tandards and should bear an official "Certified Seed" label (Figure 6.11b).

Inoculate legume seed with the Rhizobium bacteria appropriate to the species of legume (Chapter 3.

I I I I I I I I I I I I I I I I I I I ' Practice Standards and Specifications When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and legumes no more than 1/2 inch. Equipment should be cali- brated in the field for the desired seeding rate. 1 When using broadcast -seeding methods, subdivide the area into workable sec- tions and determine the amount of seed needed for each section. Apply one-half ' the seed while moving back and forth across the area, making a uniform pat- tern; then apply the second half in the same way, but moving at right angles to the first pass (Figure 6.11c). ' Figure 6.11 c Suggested pattern for broadcasting seed and fertilizer (source: NCAES Bulletin AG-69). 1 Seeding Pattern Ll Cover broadcast seed by raking or chain dragging; then firm the surface with a roller or cultipacker to provide good seed contact. Mulch all plantings immediately after seeding (Practice 6.14, Mulching). HYDROSEEDING Surface roughening is particularly important when hydroseeding, as a rough- ened slope will provide some natural coverage for lime, fertilizer, and seed. The surface should not be compacted or smooth. Fine seedbed preparation is not necessary for hydroseeding operations; lame clods, stones, and irregularities provide cavities in which seeds can lodge. Rate of wood fiber (cellulose) application should be at least 2,000 lb/acre. Apply legume inoculants at four times the recommended rate when adding in- oculant to a hydroseeder slurry. If a machinery breakdown of 1/2 to 2 hours occurs, add 501-7o more seed to the Link, based on the proportion of the slurry remaining. This should compensate for damage to seed. Beyond 2 hours, a full rate of new seed may be necessary. Lime is not normally applied with a hydraulic seeder because it is abrasive. It can be blown onto steep slopes in dry form. 1 SPRIGGING Hybrid Bermudagrass cannot be grown from seed and must be planted vegeta- tively. Vegetative methods of establishing common and hybrid Besmudagrass, ' centipedegrass, and Bahiagrass include sodding, plugging and sprigging (Chap- ter 3, Vegetative Considerations). Sprigs are fragments of horizontal stems which include at least one node (joint). They are normally sold by the bushel 1 and can either be broadcast or planted in furrows using a tractor -drawn tobac- co or vegetable transplanter. ' Furrows should be 4-6 inches deep and 2 ft apart. Place sprigs about 2 A apart in the row with one end at or above ground level (Figure 6.1 ld). Figure 6.11d Proper placement of grass ' sprigs.

Press into the top IP,2 inches of soil with a cultipacker or with a disk set nearly straight so 1 that the sprigs are not brought back to the surface. IRRIGATION Moisture is essential for seed germination and seedling establishment. Sup- plemental irrigation can be very helpful in assuring adequate stands in dry seasons or to speed development of full cover. It is a requirement for fine turf establishment and should be used elsewhere when feasible. However, irrigation is rarely critical for low -maintenance vegetation planted at the appropriate time ' of the year. Water application rates must be carefully controlled to prevent runoff. Inade- ' quate or excessive amounts of water can be more harmful than no supplemen- tal water. ' Maintenance Generally, a stand of vegetation cannot be determined to be fully established until soil cover has been maintained for one full year from planting. Inspect ' seeded areas for failure and make necessary repairs and reseedings within the same season, if possible. Reseeding —If a stand has inadequate cover, re-evaluate choice of plant mate- rials and quantities of lime and fertilizer. Re-establish the stand after seedbed preparation or over -seed the stand. Consider seeding temporary, annual species if the time of year is not appropriate for permanent seeding (Practice 6.10, Tem- porary Seeding). 6.11.3 I I I I I I I I I I I I I I I I I I I ' Practice Standards and Specifications If vegetation fails to grow, soil be must tested to determine if acidity or nutrient imbalance is responsible. ' Fertilization —On the typical disturbed site, full establishment usually requires refertilization in the second growing season. Fine turf requires annual main- tenance fertilization (Table 6.12b). Use soil tests if possible or follow the ' guidelines given for the specific seeding mixture (Tables 6.1 lc through 6.11v).

' Conditions Where Riprap is used for the following applications: Practice Applies cut -and -fill slopes subject to seepage or weathering, particularly where ' conditions prohibit establishment of vegetation, • channel side slopes and bottoms, 1 inlets and outlets for culverts, bridges, slope drains, grade stabilization structures, and storm drains, streambank and stream grades, ' • shorelines subject to wave action. Planning Riprap is a versatile, highly erosion -resistant material that can be used effec- C o n s i d e rations lively in many locations and in a variety of ways to control erosion on construc- Lion sites. GRADED VERSUS UMFORNI RIPRAP Riprap is classed as either graded or uniform. Graded riprap includes a wide mix- ture of stone sizes. Uniform riprap consists of stones nearly all the same size. Graded riprap is preferred to uniform riprap in most applications because it forms a dense, flexible cover. Uniform riprap is more open and cannot adjust as 1 effectively to movement of the stones. Graded riprap is also cheaper to install requiring less hand work for installation than uniform riprap, which must be placed in a uniform pattern, Uniform riprap may rive a more pleasing ap- pearance. Riprap sizes are designated by either the mean diameter or the weight of Lhe ' stones. The diameter specification is often misleading since the stones are usual- ly angular. However, common practice is to specify stone size by the diameter of an equivalent size of spherical stone. Table 6.15a lists some typical scenes by weight, spherical diameter, and the corresponding rectangular dimensions. These stone sizes are based upon an assumed specific weight of 165 lb/ft3. A method commonly used for specifying the range of stone sizes in graded ' riprap is to designate a diameter for which some percentage, by weight, will be smaller. For example "dss" specifies a mixture of stones in which 357D of the stone by weight would be smaller than the diameter specified. Most designs are I based on "d5o", or median size stones. Riprap and gravel are often designated by N.C. Department of Transportation specifications (Table 6.15b). 1 1 I 7 L 13 F_J LI 1 Table 6.15a Size of Rlprap Stones Mean Spherical Length Rectangular Shape Weight (lb) Diameter (ft) (ft) Width/Height (ft) 50 0.8 1.4 0.5 100 1.1 1.8 0.6 150 1.3 2.0 o.7 300 1.6 2.6 0.9 Soo 1.9 3.0 1.0 1000 2.2 3.7 1.3 1500 2.6 4.7 1.5 2000 2.8 5.4 1.8 4000 3.6 6.0 2.0 6000 4.0 6.9 2.3 8000 4.5 7.6 2.5 20000 6.1 10.0 3.3 source: Va SWCC When considering riprap for surface stabilization, it is important to anticipate visual impacts, including weed control, hazards from snakes and other animals, danger of slides and hazards to areas below steep riprap slopes, damage and pos- sible slides from children moving stones, and general safety. Proper slope selection and surface preparation are essential for successful long- term functioning of riprap. Adequate compaction of fill areas and proper use of filter blankets are necessary. Sequence of construction -Schedule disturbance of areas that require riprap protection so the placement of riprap can follow immediately after grading. When riprap is used for outlet protection, place the riprap before or in conjunc- tion with the installation of the structure so that it is in place before the first runoff event. Design Criteria Gradation-Riprap should bea well -graded mixture with 50% by weightlarger than the specified design size. The diameter of the largest stone size in such a mixture should be 1.5 times the d5a size with smaller sizes grading down to 1 inch. The designer should determine the riprap size that will be stable for design con- ditions. Having determined the design stone size, the designer should select the size or sizes that equal or exceed that minimum size based on riprap gradations commercially available in the area. ' Thickness -Construction techniques, dimensions of the area to be protected, size and gradation of the riprap, the frequency and duration of flow, difficulty and cost of maintenance, and consequence of failure should be considered when determining the thickness of riprap linings. The minimum thickness should be 1.5 times the maximum stone diameter, but in no case less than 6 inches. Quality of stone -Stone for riprap may consist of field stone or quarry stone. ' The stone should be hard, angular, of such quality that it will not break down 1 6.15.21 1 I Practice Standards and Specifications I T. 1 Table 6.15b Sizes for Riprap and Erosion Control Stone Specified by the N.C.

The specific gravity of the individual stones should be at Ieast 2.5. Size ofstone—The sizes of stones used for riprap protection are determined by purpose and specific site conditions, • Slope stabilization--Riprap stone for slope stabilization not subject to flowing water or wave action should be sized for stability for the proposed grade. The gradient of the slope to be stabilized should be less than the natural angle of repose of the stone selected. Angie of repose of riprap stones may be estimated from Figure 6.15a. Riprap used for surface stabilization of slopes does not add significant resistance to sliding or slope failure and should not be considered a retain- ing wall. The inherent stability of the soil must be satisfactory before ' riprap is used for surface stabilization. Slopes approaching 1.5:1 may re- quire special stability analysis. • Outlet protection —Design criteria for sizing stone and determining the dimensions of riprap pads at channel or conduit outlets are presented in Practice 6.41, Outlet Stabilization Structure. • Channel stab ilizationand streatnbank protection --Design criteria for sizing stone for stability of channels are contained in Appendix 8.05. Filter blanket —A filter blanket is a layer of material placed between the riprap and the underlying soil to prevent soil movement into or through the riprap.

A suitable filter may consist of a well -graded gravel or sand -gravel layer or a synthetic filter fabric manufactured for this express purpose. The design of a gravel filter blanket is based on the ratio of particle size in the overlying filter material to that of the base material in accordance with the criteria below. The designed gravel filter blanket may consist of several layers of increasingly large particles from sand to erosion control stone. A gravel Filter blanket should have the following relationship for a stable design: d15 filter < 5 day base d15 filter < 40 dls base d50 filter < 40 d5o base In these relationships, filter refers to the overlying material and base refers to the underlying material. These relationships must hold between the filter ma- terial and the base material (soil foundation) and between the riprap and the fil- ter. More than one layer of filter material may be needed. Each layer of filter material should be at least b inches thick. 6.1_.4 1 1 iu 1 ' Practice Standards and Specifications A synthetic filter fabric may be used with or in place of gravel filters. The fol- lowing particle size relationships should exist: • Filter fabric covering a base with granular particles containing 50% or less (by weight) of line particles (less than U.S. Standard Sieve no. 200 ' (0.074mm)): _ des base (mmj '1 EOS" filter fabric (mm) b. total open area of filter should not exceed 36% Filter fabric • covering other soils: a. EOS is no larger than U.S. Standard Sieve no. 70 (0.21mm) ' b. total open area of filter should not exceed 10%. *EOS - Equivalent opening size compared to a U.S. standard sieve size. No filter fabric should have less than 4% open area or an EOS less than U.S. Standard Sieve No. 100 (0.15 mm). The permeability of the fabric must be ' greater than that of the soil. The fabric may be made of woven or nonwoven monofilament yarns and should meet the following minimum requirements: • thickness 20 - 60 mils, • grab strengh 90 -120 lb, • conform to ASTM D-1682 or ASTM D-177. Filter blankets should always be provided where seepage is significant or where ' flow velocity and duration of flow or turbulence may cause the underlying soil particles to move through the riprap. ' Construction Subgrade preparation —Prepare the subgrade for riprap and filter to the re- SpecificationS quired lines and grades shown an the plans. Compact any fill required in the subgrade to a density approximating that of the surrounding undisturbed ma- terial or overfill depressions with riprap. Remove brush, trees, stumps, and other objectionable material. Cut the subgrade sufficiently deep that the finished grade of the riprap will be at the elevation of the surrounding area. Channels should ' be excavated sufficiently to allow placement of the riprap in a manner such that the finished inside dimensions and grade of the riprap meet design specifica- tions. ' Sand filter and gravel blanket —Place the filter blanket immediately after the ground foundation is prepared. For gravel, spread filter stone in a uniform layer to the specified depth. Where more than one layer of filter material is used, spread the layers with minimal mixing. ' Synthetic filter fabric —Place the cloth filter directly on the prepared founda- tion. Overlap the edges by at least 12 inches, and space anchor pins every 3 ft along the overlap. Bury the upper and lower ends of the cloth a minimum of 12 inches below ground. Take care not to damage the cloth when placing riprap. If damage occurs remove the riprap and repair the sheet by adding another layer 1 b.1 5.S I � 0 of filter material with a minimum overly of 12 inches around the damaged area. P g ' If extensive damage is suspected, remove and replace the entire sheet. Where large stones are used or machine placement is difficult, a 4-inch layer of fine gravel or sand may be needed to protect the filter cloth. ' Stone placement —Placement of riprap should follow immediately after place- ment of the filter. Place riprap so that it forms a dense, well -graded mass of stone ' with a minimum of voids. The desired distribution of stones throughout the mass may be obtained by selective loading at the quarry and controlled dumping during final placement. Place riprap to its full thickness in one operation. Do ' not place riprap by dumping through chutes or other methods that cause segrega- tion of stone sizes. Take care not to dislodge the underlying base or filter when placing the stones. ' The toe of the riprap slope should be keyed to a stable foundation at its base as shown in Figure 6.15b. The toe should be excavated to a depth about 1.5 times the design thickness of the riprap and should extend horizontally from the slope. ' The finished slope should be free of pockets of small stone or clusters of large stones. Hand placing may be necessary to achieve the proper distribution of ' stone sizes to produce a relatively smooth, uniform surface. The finished grade of the riprap should blend with the surrounding area. No overfalI or protrusion of riprap should be apparent.

References Runoff Conveyance Measures 6.31, Riprap-lined and Paved Channels Outlet Protection ' 6.41, 0udet Stabilization Structure 1 1 ' Practice Standards and Specifications 6.30 Definition A channel with vegetative lining constructed to design cross section and grade for conveyance of runoff. Purpose To convey and dispose of concentrated surface runoff without damage from erosion, deposition, or flooding. Conditions Where This practice applies to construction sites where: ' Practice Applies damage from flooding; • concentrated runoff will cause erosion or • a vegetative lining can provide sufficient stability for the channel cross section and grade; • slopes are generally less than 5%, ' space is available for a relatively large cross section. Typical uses include roadside ditches, channels at property boundaries, outlets for diversions, and other channels and drainage of low areas. ' Planning LOCATION Considerations Generally, channels should be located to conform with and use the natural ' drainage system. Channels may also be needed along development boundaries, roadways, and backlot lines. Avoid channels crossing watershed boundaries or ridges. Plan the course of the channel to avoid sharp changes in direction or grade. S'tte development should conform to natural features of the land and use natural drainageways rather than drastically reshape the land surface. Major recon- ' figuration of the drainage system often entails increased maintenance and risk of failure.. Grass -lined channels must not be subject to sedimentation from disturbed areas. ' An established grass -lined channel resembles natural drainage systems and, therefore, is usually preferred if design velocities are below 5 ft/sec. Velocities up to 6 ft/sec can be safely used under certain conditions (Table 8.05a, Appen- dix 8.05). Establishment of a dense, resistant vegetation is essential. Construct and veg- etate grass -lined channels early in the construction schedule before grading and paving increase the rate of runoff. Geotextile fabrics or special m ulch protection such as fiberglass roving or straw and netting provide stability until the vegetation is fully established. These protective liners must be used whenever design velocities exceed 2 ft/sec for bare soil conditions. It may also be necessary to divert water from the channel until vegetation is established or to line the channel with sod. Sediment traps may be needed at channel inlets and outlets. 'i..'{1.: 1 I 1 1 7 L 0 1 V-shaped grass channels generally apply where the quantity of water is small, such as in short reaches along roadsides. The V-shaped cross section is least ' desirable because it is difficult to stabilize the bottom where velocities may be high. ' Parabolic grass channels are often used where larger flows are expected and space is available. The swble-like shape is pleasing and may best fit site condi- tions. ' Trapezoidal grass channels are used where runoff volumes are large and slope is low so that velocities are nonerosive to vegetated linings. Subsurface drainage, or riprap channel bottoms, may be necessary on sites that are subject to prolonged wet conditions due to long duration flows or high water ' tables (Practice 6.81, Subsurface Drain and Practice 6.31, Riprap-lined and Paved Channels). OUTLETS Outlets must be stable. Where channel improvement ends, the exit velocity for the design flow must be nonerosive for the existing field conditions. Stability conditions beyond the property boundary should always be considered (Prac- ' Lice 6A1, Outlet Stabilization Structure). AREA ' Where urban drainage area exceeds 10 acres, it is recommended that grass -lined i channels be designed by an engineer experienced in channel design. Design Criteria Capacity —As a minimum, grass -lined channels should carry peals runoff from the 10-yr storm without eroding. Where flood hazard exists, increase the capacity according to the potential damage. Channel dimensions may be deter- mined by using design tables with appropriate retardance factors or by Manning's formula using an appropriate "n" value. When retardance factors are used, the capacity is usually based on retardance "C" and stability on retardance "D" (References: Appendix, 3,05). Velocity —The allowable design velocity for grass -lined channels is based on soil conditions, type of vegetation, and method of establishment (Table 8.05a, ' Appendix 8.05). If design velocity of a channel Lo be vegetated by seeding exceeds ? ft/sec, a temporary channel liner is required. The design of the liner may be based on ' peak flow from a ?-yr storm. if vegetation is established by sodding, the per- missible velocity for established vegetation shown in Table 8.05a may be used and no temporary later is needed. Whether a temporary lining is requried or not ' permanent channel linings must be stable for the 10-yr storm. A design approach based on erosion resistance of various liner materials developed by the Federal Highway Administration is presented in Appendix 8.05. Cross section —The channel shape may be parabolic, trapezoidal, or V-shaped, depending on need and site conditions (Figure 6.30a). 1 1 6.20.' I 1 Practice Standards and Specifications 7 1 Figure 6.30a Cross section geometry of triangular, parabolic, and trapezoidal Triangular "V" channels.

Side slopes —Grassed channel side slopes generally are constructed 11 or flat- ter to aid in the establishment of vegetation and for maintenance. Side slopes of V-shaped channels are usually constructed 6:1 or flatter along roadways for safety. Depth and width —The channel depth and width are proportioned to meet the needs of drainage, soil conditions, erosion control, carrying capacity and site conditions. Construct channels a minimum of 0.2 ft larger around the periphery to allow for soil bulking during seedbed preparations and sod buildup. Grade —Either a uniform or gradually increasing grade is preferred to avoid sedimentation. Where the grade is excessive, grade stabilization structures may be required or channel linings of riprap or paving should be considered (Prac- tice 6.82, Grade Stabilization Structure). I I I I I I I I I I I I L7 I I I I I I 1 o Drainage --Install subsurface drains in locations with high water tables or ' seepage problems that would inhibit establishment of vegetation in the channel. Stone channel bottom lining may be needed where prolonged low flow is an- ticipated. ' Outlets —Evaluate the outlets of all channels for carrying capacity and stability and protect them from erosion by limiting the exit velocity (Practice 6.41.0ut- let Stabilization Structure). ' Sedimentation protection —Protect permanent grass channels from sediment produced in the watershed, especially during the construction period. This can ' be accomplished by the effective use of diversions, sediment traps, protected side inlets, and vegetative filter strips along the channel. ' Construction 1. Remove all trees, brush, stumps, and other objectionable material from the Specifications foundation area and dispose of properly. ' Z. Excavate the channel and shape it to neat lines and dimensions shown on the plans plus a 0.2-ft overcut around the channel perimeter to allow for bulking during seedbed preparations and sod buildup. ' 3. Remove and properly dispose of all excess soil so that surface water may enter the channel freely. 4. The procedure used to establish grass in the channel will depend upon the severity of the conditions and selection of species. Protect the channel with mulch or a temporary liner sufficent to withstand anticipated velocities during the establishment period (Appendix 8.05). Maintenance During the establishment period, check grass -lined channels after every rain- fall. After grass is established, periodically cheek the channel, check it after every heavy rainfall event. Immediately make repairs. It is particularly impor- tant to check the channel outlet and all road crossings for bank stability and ' evidence of piping or scour holes. Remove all significant sediment accumula- tions to maintain the designed carrying capacity. Keep the grass in a healthy, vigorous condition at all times, since it is the primary erosion protection for the channel (Practice 6,1 I, Perrrranent Seeding). 1 References Surface Stabilization 6.11, Permanent Seeding ' 6.12, Sodding 6.14, Mulching ' Outlet Protection 6.41, Outlet Stabilization Structure Other Related Practices 6.81, Subsurface Drain 6.82, Grade Stabilization Structure 1 1 r). O } I 1 1 �I Practice Standards and Specifications 6.41 • . ' Definition A structure designed to control erosion at the outlet of a channel or conduit. ' Purpose To prevent erosion at the outlet of a channel or conduit by reducing the velocity of flow and dissipating the energy. ' Conditions Where This practice applies where the discharge velocity of a pipe, box culvert, diver - Practice Applies sion, open channel, or other water conveyance structure exceeds the permissible ' velocity of the receiving channel or disposal area. Planning The outlets of channels, conduits, and other structures are points of high erosion ' Considerations potenval, because they frequently carry flows at velocities that exceed the al- lowable limit for the area downstream. To prevent scour and undermining, an outlet stabilization structure is needed to absorb the impact of the flow and reduce the velocity to non -erosive levels. A riprap-lined apron is the most com- monly used practice for this purpose because of its relatively low cost and ease of installation. The riprap apron should be extended downstream until stable ' conditions are reached even though this may exceed the length calculated for design velocity control. Riprap-stilling basins orplunge pools reduce flow velocity rapidly. They should be considered in lieu of aprons where overfalls exit at the ends of pipes or where high flows would require excessive apron length. Consider other energy dis- sipators such as concrete impact basins or paved outlet structures where site con- ditions warrant, (Figure 6.41a). ' Design Criteria Design procedures for riprap outlet structures are presented in Appendix8.06. The criteria for design of riprap outlets are: Capacity-10-yr, peak runoff or the design discharge of the water conveyance . structure, whichever is greater. Tailwater depth —Determine the depth of tailwater immediately below the ' pipe outlet based on the design discharge plus other contributing flows. If the tailwater depth is less than half the diameter of the outlet pipe and the receiving stream is sufficiently wide to accept the divergence of flow, it is classed as a ' minimum tailwater condition. If the tailwater depth is greater than half the pipe diameter, it is classed as a maximum tailwater condition. Pipes that out- let onto broad flat areas with ao defined channel may be assumed to have a min- imum tailwater condition unless site conditions indicate otherwise (Figure ' 6.41 b). Apron size —The apron length and width can be determined according to the tailwater condition. If the water conveyance structure discharges directly into a well-defined channel, extend the apron across the channel bottom and up the channel banks to an elevation of 0.5 ft above the maximum tailwater depth or 1 to the top of the bank, whichever is less (Figure 6.41c) 1 Practice Standards and Specifications A do Y A do Determine the maximum allowable velocity for the receiving stream, and design the riprap apron to reduce flow to this velocity before flow leaves the apron. Calculate the apron length for velocity control or use the length required to meet stable conditions downstream, whichever is greater. Grade —Ensure that the apron has zero grade. There should be no overfall at the end of the apron; that is, the elevation of the top of the riprap at the downstream end should be the same as the elevation of the bottom of the receiv- ing channel or the adjacent ground if there is no channel. Alignment —The apron should be straight throughout its entire length, but if a curve is necessary to align the apron with the receiving stream, locate the curve in the upstream section of riprap. Materials —Ensure that riprap consists of a well -graded mixture of stone. Larger stone should predominate, with sufficient smaller sizes to fill the voids between the stones. The diameter of the largest stone size should be no greater than 1.5 times the dso size.

Stone quality --Select stone for riprap from field stone or quarry stone. The stone should be hard, angular, and highly weather -resistant. The specific gravity ' of the individual stones should be at least 2.5. Filter —Install a filter to prevent soil movement through the openings in the ' riprap. The filter should consist of a graded gravel layer or a synthetic filter cloth. Design filter blankets by the method described in Practice 6.15, Riprap. ' Construction 1. Ensure that the subgrade for the filter and riprap follows the required lines Specifications and grades shown in the plan. Compact any fill required in the subgrade to the density of the surrounding undisturbed material. Low areas in the subgrade on ' undisturbed soil may also be filled by increasing the riprap thickness. 2. The riprap and gravel filter must conform to the specked grading limits ' shown on the plans. 3. Filter cloth, when used, must meet design requirements and be properly protected from punching or tearing during installation. Repair any damage by removing the riprap and placing another piece of filter cloth over the damaged area. All connecting joints should overlap a minimum of 1 fL If the damage is extensive, replace the entire filter cloth. ' 4. Riprap may be placed by equipment, but take care to avoid damaging the fil- ter. t5. The minimum thickness of the riprap should be 1.5 times the maximum stone diameter. ' 6. Riprap may be field stone or rough quarry stone, It should be hard, angular, highly weather -resistant and well graded. t 7. Construct the apron on zero grade with no overfall at the end. Make the top of the riprap at the downstream end level with the receiving area or slightly below it. ' 8. Ensure that the apron is properly aligned with the receiving stream and preferably straight throughout its length. If a curve is needed to tit site candi- ' lions, place it in the upper section of the apron. 9. Immediately after construction, stabilize all disturbed areas with vegetation (Practices 6.10, Temporary Seeding, and 6.11, Permanent Seeding). ' Maintenance ee Inspect riprap outlet structures after heavy rains to see if any erosion around or below the riprap has taken place or if stones have been dislodged. Immediately make all needed repairs to prevent further damage. 1 6.-41.- 1 1 1 1 1 1 PCS Phosphate Reclamation Subject: PCS Phosphate Reclamation Date: Tue, 16 Jan 2001 12:56:15 -0500 From: Charles Gardner <Charles.Gardner@ncmail.net> Organization: Division of Land Resources To: Floyd Williams <Floyd.Williams@ncmail.net>, Tracy Davis <Tracy.Davis a ncmail.net>, "Jim.Simons" <Jim.

Cooper, Jr. VP/General Manager Phosphate Production PCS Phosphate Company Post Office Box 48 Aurora, North Carolina 27806 Dear Mr. Cooper: p �� 0 W C LDEC g ,,- WASLAND HIING ONAR IOON NALLITY IOFFICE DEC 99 1 CF_NR ` LAND QUALITY SECTION This correspondence confirms our meeting of November 29, 2000, regarding PCS Phosphate Company's application for a Department of the Army (DA) individual permit to continue its surface mining operations on a 3,604 acre tract of land located on the Hickory Point peninsula, adjacent to the Pamlico River, South Creek and associated tributaries, north of Aurora, in Beaufort County, North Carolina. Also in attendance was Mr. Bill Biddlecome of my staff, and Messrs. Jeff Furness and Ross Smith of your staff. The purpose of this letter is to expound on our discussions regarding Corps of Engineers' policy on preparation of environmental impact statements. As discussed, based upon the size and scope of your project, it is likely that the preparation of a detailed environmental impact statement (EIS) will be required prior to the issuance of a DA permit. Pursuant to Headquarters, U.S. Army Corps of Engineers guidance, dated December 17, 1997, any Corps district preparing an EIS on a permit action will use a "third party contractor" as the primary method to prepare all or part of a project specific EIS or to obtain required information (40 CFR 1500-1508). A "third party contract" refers to the preparation of an EIS by a contractor paid by the applicant but who is selected and supervised directly by the Wilmington District Engineer. I have enclosed a copy of the Headquarters guidance referenced above. I also provided copies to Messrs. Furness and Smith at the subject meeting. This issue will be addressed further as evaluation of your permit application progresses. -2- Thank you for your time and cooperation.

Appendix B, 33 CFR Part 325, provides policy guidance on preparation of National Environmental Policy Act documents for the TT.S. ?.,-my Corps of Engineers Regulatory Program. This regulation provides that the district engineer may prepare as Environmental Impact Statement (EIS) or may obtain information to prepare an EIS, either with his/her own staff or by choosing a contractor, either at the expense of the Corps or the expense of the applicant, who reports directly to the district engineer (see paragraph (3), 8b, Sc, and 8f). Due to budgetary constraints, preparing a project specific EIS at the expense of the Corps can no longer be funded. 2. Effective immediately, any Corps district preparing an EIS on a permit action will use a "third parry contractor" as the primary method to prepare all or part of a project specific EIS or to obtain required information (40 CFR 1500-1508). gird party contract" refers to the preparation of an EIS by a contractor paid by the applicant but who is selected and supervised directly by the district engineer (Corps Regulatory Branch). (See 40 CFR 1506.5(c) and Council on Environmental Quality's (CEQ) Forty Most Asked Questions Concerning CEQ's National Environmental Policy Act Regulations, n16 and *17) Contractor selection by the Corps for a Regulatory Program EIS will be as follows: The Corps will select from the applicant's list the first contractor that is fully acceptable to the Corps, using the applicant's order of preference. The procedures outlined in 40 CFR 1500-1508 and CEQ's forty questions must be followed. Furthermore, the Corps is responsible for final acceptance of the draft and final EIS. 3. Appendix B, 33 CFR Part 325, provides that the district engineer may require the applicant and/or his/her consultant to furnish information required for an EIS. The applicant and/or his/her consultant will then provide the information for the Corps use in preparing an EIS. This is an option which may be utilized in preparing a project specific EIS; however, to manage Corps resources more efficiently and equitably, this approach will be utilized by a district in preparing a project specific EIS only when for some reason the third party contracting cannot be used. If this method is used, the applicant is responsible for providing required information and data to the Corps. The Corps is responsible for review and acceptance of required information, data, or drafts and must be especially vigilant in identifying and eliminating any bias that could exist in a draft National Environmental Policy Act document prepared by a contractor selected and supervised by an applicant. The district engineer (Corps Regulatory Branch) has the final determination for EISs prepared by the applicant and his/her consultant of whether the data provided is adequate and accurate. The Corps will carefully review the applicant's drafts to ensure they are technically adequate and not biased. CECW-OR SUBJECT: Guidance on Environmental Impact Statement Preparation, Corps Regulatory Program 4. Of course, a programmatic EIS will still have a substantial portion of the effort conducted and funded by the Corps. However, even for programmatic EIS's, the Corps can, and should, identify applicant groups, States, and/or local Governments to cost share in the effort. Whenever an agency prepares a programmatic EIS, the requirements of 40 CFR 1506.1(c) present potential legal and practical problems for processing any Corps permit related to the programmatic EIS (especially if the permit would require a project specific EIS). For that reason and due to budget implications, any decision to do a programmatic EIS will be reviewed and approved by CECW-OR before a commitment is entered into for any programmatic EIS. 5. Due to Regulatory Program budget limits, all Regu atcry Program EIS's rust be managed in the Regulatory Branch and primarily reviewed in the Regulatory Branch. The Regulatory Branch will only contract out work to other Corps elements, other Federal agencies, or private consultants, when additional expertise beyond that available in the Regulatory Branch is necessary or where it makes good business sense for the Regulatory Program. 6. Ifyou have any questions, please contact Ms. Colleen Charles, at (202) 761-1794.

This project will be evaluated pursuant to Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 403) and Section 404 of the Clean Water Act (33 U.S.C. 1344). The purpose of this letter is to initiate the Scoping process for evaluation of this permit application (see attached). The project as proposed will adversely effect 2,530 acres of wetlands. Wetland types proposed to be impacted include disturbed herbaceous and shrub -scrub assemblages, pine plantations, pine flatwoods, mixed pine/hardwood forest, hardwood forest, bottomland hardwood forest and brackish marsh. Additionally, 49 acres of waters of the United States, including navigable waters, are proposed to be effected. Jacks Creek, Jacobs Creek, Drinkwater Creek, Huddy Gut, Huddles Cut and several unnamed tributaries including existing mitigation areas (Creation I and Creation In are proposed to be impacted. A large percentage of these waters are densely vegetated with several species of submerged aquatic vegetation (SAV) including widgeon grass (Ruppia maritima), Eurasian water-milfoil (Myriophyllum spicatum), horned pondweed (Zannichellia palustris) and hornwort (Ceratophyllum demersum). Major considerations of the environmental document that will be prepared include evaluations of biotic communities including wetlands, soils, geology, hydrology, water quality and land use. A full range of environmental, social and economic issues will be evaluated, including mitigation of potential adverse impacts and avoidance of specific impacts where practicable. I would appreciate any information you might have that would be helpful in evaluating the potential environmental impacts of this project. Accordingly, please provide your comments to me, in writing, by January 12, 2001. I will be contacting you in the near future to coordinate the evaluation of this project. Thank you for your time and cooperation.

Pro osed im act too en water and SAV The proposed activity will affect forty-nine (49) acres of open water (reference the creeks category in the legend of Attachment G of the permit application). The affect to submerged aquatic vegetation (SAV) is the same as the open water quantity because SAVs are present during a portion of the year in all of the identified open waters. "Submerged aquatic macrophytes found in open waters include primarily widgeon grass (Ruppia rnaritima), with Eurasian water-zrulfoil (Myriophyllum spicatum) and horned pondweed (Zannichellia palustris) also occurring" (P- 4-29 of FEIS, August, 1996) (Ceratophyllurn demersum) was found during the I998 stream hornwort program. monitoring 2.

Time frame for mining the remainder of Alternative E Current mine plan projections indicate the completion of phosphate ore recovery within the Alternative E permit boundary in 2009. Development activities to provide access to this area require surface impacts prior to the actual mining of the phosphate ore. Current plans indicate that development activities, primarily land clearing, that impact surface features will be completed in 2006 to 2007. Please note that these schedules are based on projected market requirements and ore recovery which may vary. As per your recommendation, we are preparing the CAMA permit application package to be sent to the Division of Coastal Management and the 401 Water Quality Certification application package to be sent to the Division of Water Quality.

Tracy Subject: Limestone Addition Letter Date: Tue, 21 Nov 2000 10:55:19 -0500 From: JFumess@Pcsphosphate.com To: tracy.davis@ncrnail.net Dear Tracy: As we spoke about on the phone, we are currently experiencing a sand scour area in the mine where there is very little clay available to be used to blend with gypsum for land reclamation. This has resulted in the pH of the blend to drop into the 3 range. We have countered the problem by hauling clay from another area and adding it to the blend tank, however we still would like to raise the pH some more. We propose to add agricultural limestone to the blend tank, and would like approval for a 1 week trial to see how it works. After the trial, we will report to you the results, and if they are positive, ask you for more formal approval to add limestone on an as -needed basis if we run into this situation again in the future. Attached to this e-mail is a memo from John Robinson to Terry Baker outlining the details of the test. Thank you for your prompt consideration of this request.

Robinson Location Aurora Subject Limestone Addition to Blend Trial Based on test work completed by Technical Services, limestone addition to the gypsum/clay blend tank will increase the pH of the blend mixture. It is recommended that limestone addition be tested along with the supplemental clay addition for a one -week trial. This trial will confirm the ability of the limestone to provide additional neutralization of the gypsum in periods of low clay availability. The trial will also let us evaluate the handling characteristic of the limestone material and any other special needs should the limestone addition be necessary in the future. The test will be conducted in conjunction with the current supplemental clay addition at the blend tank. Test work performed by Technical Services has indicated that addition of limestone at a 75 tons per day rate will provide sufficient neutralization to reach an average neutralization of 5.5 pH. This is in addition to the current supplement of 60 tons per hour of Yorktown clay. In order to confirm the bench scale neutralization and determine and handling concerns it is necessary to conduct a one week trial. We propose to add approximately 75 tons per day of High Calcium Ag Lime to the blend tank. It is proposed to ship the material in dump trucks from the manufacturing facility to a ramp near the blend tank. The material will be added to the blend tank by a back hoe that is currently positioned at the blend tank for adding the Yorktown clay. We should seek permission for this one -week trial. If the material performs satisfactorily we should seek permission to add this material or similar substitute on an as needed basis. Please don't hesitate to call me if additional questions arise. J.

Evaluation of quality assurance and quality control (QA/QC) results for the source material metal analyses. The QA/QC results from the source study are evaluated based on the Data Quality Objectives (DQOs) listed below in Table 1. All initial calibrations used met the requirement that r be greater than 0.999. All continuing calibrations were within a 10% deviation. Results for the SRMs met the DQOs. Values for 15 of 16 metals were within the certified limits established by the National Research Council of Canada. Concentrations of As in BCSS-1 were 2.7 µg/g higher (24% higher) than certified values of 11.1 :± 1.4 µg/g. The DQO is set for ±20% with >85% of analytes meeting specification. With 15/16 correct answers, 94% of the SRM values ;net specifications. The slightly higher As levels in BCSS-1 result from matrix effects and the spike correction used. None of the blanks exceeded 5x the MDLs. Reviewers should note that blanks are in ng/mL (ppb) and MDLs are in µg/g (ppm). Therefore, the Cd blank of 0.16 ng/mL (ppb) would be 0,00016 µg/mL (ppm). Corrected to µg/g material, the blank is roughly equivalent to 0.007 µglg and 3.5x greater than the MDL for the sediment method. This does not affect any Cd data and is partially an artifact of background in le 7CP-MS system at very low levels. The very small Si blank is insignificant relative to Si levels in the source material. Matrix spikes showed recovery within 90-110% for every element/sample except those where the metal concentration in the sample was very low. The choice of samples to use for spike recovery is random. For example, concentrations of Ag in the BWB spoil were only 0.03 µg/g and the spike recovery was only 80%. Such absolute differences in concentrations were not a factor in using and interpreting the data from the source study. Analytical precision averaged 7% (RSD) with no values greater than 25%.

Evaluation of quality assurance and quality control (QAIQC) results for metal analyses. The QA/QC results from the source study are evaluated based on the Data Quality Objectives (DQOs) listed below in Table 1. All initial calibrations used met the requirement that (r) be greater than 0.999. All continuing calibrations were within a 10% deviation. Sediment Metals. Results for the sediment SRMs met the DQOs. All results were within the certified limits established by the National Research Council of Canada (NRC). None of the sediment metal blanks exceeded 5x the MDLs. Reviewers should note that blanks are in ng/mL (ppb) and MDLs are in µg/g (ppm) and % (where 1 % equals 10,000 µg/g). Therefore, the Ag concentration of Blank #1, at 0.08 ng/mL (ppb), would be 0.00008 µgiml, (ppm). Corrected to µg/g material, the blank is roughly equivalent to 0.003 µg/g and 3x lower than the MDL for the sediment method. The highest blank concentrations were observed for Fe, 152 ng/mL in Blanks #1 and #2. Converted to µg/g material, this concentration is roughly equivalent to 7 µg/g, and less than the MDL value of 0.001% (10 µg/g). The blank concentrations for Cd, Mo, Se and Zn are all similarly below their respective MDL values. Matrix spike recoveries for the sediment samples were within the range of 90-110% for all elements except Cd from Station 8 (87.2%). No spike correction was applied because the other spiked samples all exceeded 90°/6 recovery for Cd. Analytical precision from laboratory duplicates was better than 10% for all elements except Ag and Cd in sediment from Station 17 (12.9% and 23.6%, respectively). The lower precision for these elements in this sample is due to their very low concentrations. The DQO requirements for analytical precision were met (Table 1). Dissolved Metals. Results for the dissolved metal SRMs met the DQOs. All results were within the certified limits established by the NRC and National Institute of Standards and Technology (NIST). None of the dissolved metal blanks exceeded 5x the MDLs for As, Cd, Mo and Zn. Reviewers should note that both the dissolved blank metal concentrations and MDL values are in µg/L (ppb). The greatest blank concentrations relative to MDL values were observed for Cr, at 0.104-0.127 µg/L. The bulk of the Cr blank is derived from the membrane filters required in the extraction/preconcentration procedure. These fitters are acid -washed prior to use, but a small amount of residual Cr remains. This small, residual Cr cannot be removed from the membrane material without significantly damaging the filter. The blank concentrations for Cu also exceed 5x the MDL. In this case, the blank is not filter related and comes from the reagents needed to preform the metal extraction/preconcentration. Reagents from several commercial sources were tested and only the highest purity materials were selected for use. Matrix spike recoveries for the dissolved metal samples were within the range of 90-110% for all elements. Analytical precision from laboratory duplicates was better than 10% for all elements. Particulate Metals. Results for dissolved metals in the SRMs met the DQOs. All results were within the certified limits established by the NRC and MIST. None of the particulate metal blanks exceeded 5x the MDLs. Reviewers should note that blanks are in ng/mL (ppb) and. MDLs are in µg/g (ppm) and % (where I % equals 10,000 µg/g). Therefore, the As concentration of Blank #1, at 0.61 ng/mL (ppb), would be 0.00061 µg/mL (ppm). Corrected to µg/g material, the blank is roughly equivalent to 3 µg/g and 2x lower than the MDL value. The greatest blank concentration was again observed for Fe, 30 ng/mL in Blank #1. Converted to µg/g material, this concentration is equivalent to 30 µg/g, and —7x less than the MDL value of 0.02% (200 µgig). Blank concentrations for Cd, Cr, Cu, Mo and Zn are all below their respective MDL values. Matrix spike recoveries for the particulate metal samples were within the range of90-110% for ail elements. Analytical precision from laboratory duplicates was better than 10% for all elements except Mo in particulate samples from Station 16 (10.9%); however, the DQO requirements for analytical precision were met (Table 1). Tissue Metals. Results for metals in the tissue SRMs met the DQOs. All results were within the certified limits established by the NRC. None of the tissue metal blanks exceeded 5x the MDLs. Reviewers should note that blanks are in ng/mL (ppb) and MDLs are in µg/g (ppm) dry weight. Therefore, the Ag concentration of Blank #1, at 0.09 ng/mL (ppb), would be 0.00009 µg/mL (ppm). Corrected to µg/g material, the blank is roughly equivalent to 0.004 µg/g and 2x greater than the MDL value. The greatest blank concentration was again observed for Fe, 121 ng/mL in Blanks #1 and #2. Converted to µg/g material, this concentration is equivalent to 5 µg/g, and 2x greater than the MDL value of 2.5 µg/g. Of the remaining analytes, tissue blank concentrations of Cd, Cu and Se were below their respective MDL values; As, Cr and Zn blank concentrations ranged from 1-4x their NML values. Thus, the DQO requirements were met. Matrix spike recoveries for the tissue metal samples were within the range of 90-110% for all elements except As in two tissue digests (averaging 69.5% and 83.7%, respectively) and Cd in one tissue digest (averaging 74.6%). Arsenic and Cd concentrations in these tissue digests have been corrected for their low spike recovery. Empirically, the low recoveries seem to havebeen associated with tissues and organisms that were noticeably oily in texture. A modification was made to the digestion procedure to correct this problem; the amount of hydrogen peroxide used to oxidize the tissue samples was doubled. Subsequently, all matrix spike recoveries were within the desired 90- 110% range. Analytical precision from laboratory duplicates was better than 10% for all elements except Ag in Longnose Gar from the Pamlico River (17.7%) and Se in crab tissue from Station 12 (13.1%). In the case of Ag, the comparatively low precision is due to the very low tissue concentrations present. For Se in crab tissue from Station 12, the relatively low precision may be due to inhomogeneity between the samples of crab flesh; however, the DQO requirements for analytical precision were met (Table 1).

Box 27687 Raleigh, North Carolina 27687 Dear Mr. Davis: AURORA In reviewing the mapping associated with the September 1998 Mine Permit 7-1 modification on the NCPC Tract, we discovered a small area in the "Ancillary Area" category inadvertently left out. This area is highlighted on the enclosed maps, and totals 0.8 acres. These ancillary areas, as you may recall from 1998, are included in the mine permit for use as surface facilities (haul roads, pipeline corridors, existing office and maintenance buildings, lay -down yards, etc.). PCS Phosphate would like your approval to modify Mine Permit 7-1 by adding the 0.8-acre piece on to the "Ancillary Areas" category in the area highlighted on the enclosed drawings. Enclosed is a check in the amount of $500.00 to cover the modification fee.

We have just received the draft report from Aqua Survey, Inc., the firm that performed the study. It is 60 pages long and pretty involved. We have not worked with this firm before, and the report is in pretty rough shape. It is confusing at times the way it is laid out and formatted, the executive summary is over 13 pages long, and discussion is intermixed with results instead of in distinct sections. In order for us to work with Aqua Survey in re -formatting the report and making it clearer and more understandable, we request a 30-day delay in the required date for submission, to May 1, 2000. In the long run, this will be more efficient for everyone involved, because if it is submitted as -is, we will spend a great deal of time answering questions and clearing up confusion from agency personnel trying to read and follow the report. Thank you for ,your consideration of this request.

On August 27, 1997, The U.S. Army Corps Of Engineers Pursuant To Section 404 Of The Clean Water Act Issued To PCS Phosphate Company Inc. A Department Of The Army Permit No. 198800449 For A Surface Mine (Open Pit) Operation To Mine Phosphate Rock Identified As Alternative E And Described In The EIS Issued For This Project. The Permitted Wetland Loss Is 1,263 acres And The Permit Expires On December 31, 2017. The Approved Area Of Work Includes All Of Alternative E Except That Bottomland Hardwoods Located In Mine Block 20 Are Excluded. PCS Phosphate Has Revised The The Proposal To: a. DELETE ALL OF MINE BLOCK 20. b. DELETE THE SOUTHWESTERN CORNER OF ALTERNATIVE E (EXCEPT FOR 1.1 ACRES NEEDED TO ACCOMMODATE FUTURE RAILROAD LOCATION). c. INCREASE THE WIDTH OF THE CENTRAL PORTION OF ALTERNATIVE E. A public notice was issued on December 23,1999 that did not contain the map titled "Proposed Changes For Permit Amendment" PCS Phosphate Company, Inc. dated November 29, 1999. This Public Notice Revision/Modification includes the described map. The following description of work is taken from data provided by the applicant in a letter dated October 13, 1999. The proposed permit modification would change the boundaries of the approved area of work to include 17.7 fewer acres of wetlands and would reduce wetland mitigation requirements by 36.5 acres. The enclosed map shows the location and proposed L/L/ � r/4 P,944�1 -2- changes to the original permitted area. The report reflects the recent collection and analysis of 1999 biotic communities data as requested by the Wilmington district Corps of Engineers. The proposal is to reduce the wetland impacts for the proposal area from 162.3 acres to 144.6 acres and to decrease the wetland mitigation from 324.6 acres to 288.1 acres. Additionally the proposal is to increase the upland impacts from 57.7 acres to 111.5 acres within the proposal area. These reductions and additions are illustrated in the enclosed map titled "Proposed Changes For Permit Amendment" PCS Phosphate Company, Inc. dated November 29, 1999. This proposal shall be reviewed for the applicability of other actions by North Carolina agencies such as: a. The issuance of a Water Quality Certification under Section 401 of the Clean Water Act by the North Carolina Division of Water Quality NCDWQ). b. The issuance of a permit to dredge and/or fill under North Carolina General Statute 113-229 by the North Carolina Division of Coastal Management (NCDCM). c. The issuance of a permit under the North Carolina Coastal Area Management Act (CAMA) by the North Carolina Division of Coastal Management (NCDCM) or their delegates. d. The issuance of an easement to fill or otherwise occupy State-owned submerged land under North Carolina General Statute 143-341(4), 146-6, 146-11, and 146-12 by the North Carolina Department of Administration (NCDA) and the North Carolina Council of State. e. The approval of an Erosion and Sedimentation Control Plan by the Land Quality Section, North Carolina Division of Land Resources (NCDLR), pursuant to the State Sedimentation Pollution ControI Act of 1973 (NC G.S. 113 A-50-66). The requested Department of the Army (DA) permit will be denied if any required State or local authorization and/or certification is denied. No DA permit will be issued until a State coordinated viewpoint is received and reviewed by this agency. Recipients of this notice are encouraged to furnish comments on factors of concern represented by the above agencies directly to the respective agency, with a copy furnished to the Corps of Engineers. This public notice revision is being considered pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this revision. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. -3- The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties Iisted as being eligible for inclusion therein, and this worksite is not a registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer, based on available information, is not aware that the proposed activity will affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal mast be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest -4- factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Generally, the decision whether to issue this Department of the Army (DA) permit will not be made until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The NCDWQ considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the DA permit serves as application to the NCDWQ for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Water Quality (NCDWQ), Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Water Quality (NCDWQ), Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before January 28, 2000, Attention: Mr. John Dorney. Written comments pertinent to the proposed work, as outlined above, will be received in this office, Attention: William J. Biddlecome, Washington Regulatory Field Office, Post Office Box 1000, Washington, North Carolina 27889-1000, until 4:15 p.m., January 28, 2000, or telephone (252) 975-1616, extension 27.

On August 27, 1997, The U.S. Army Corps Of Engineers Pursuant To Section 404 Of The Clean Water Act Issued To PCS Phosphate Company Inc. A Department Of The Army Permit No. 198800449 For A Surface Mine (Open Pit) Operation To Mine Phosphate Rock Identified As Alternative E And Described In The EIS Issued For This Project. The Permitted Wetland Loss Is 1,263 acres And The Permit Expires On December 31, 2017. The Approved Area Of Work Includes All Of Alternative E Except That Bottomland Hardwoods Located In Mine Block 20 Are Excluded. The Original Public Notice Was Issued On August 1, 1988. PCS Phosphate Has Revised The Proposal To: a. DELETE ALL OF MINE BLOCK 20. b. DELETE THE SOUTHWESTERN CORNER OF ALTERNATIVE E (EXCEPT FOR 1.1 ACRES NEEDED TO ACCOMMODATE FUTURE RAILROAD LOCATION). c. INCREASE THE WIDTH OF THE CENTRAL PORTION OF ALTERNATIVE E. The following description of work is taken from data provided by the applicant in a letter dated October 13, 1999. The proposed permit modification would change the boundaries of the approved area of work to include 17.7 fewer acres of wetlands and would reduce wetland mitigation requirements by 36.5 acres. The enclosed map shows the location and proposed changes to the original permitted area. The report reflects the recent collection and analysis of 1999 biotic communities data as requested by the Wilmington district Corps of Engineers. The proposal is to reduce the wetland impacts for the proposal area from 162.3 acres to 144.6 acres and to decrease the wetland mitigation from 324.6 acres to 288.1 acres. Additionally the proposal is to increase the upland impacts from 57.7 acres to 111.5 acres within the proposal area. These reductions and additions are illustrated in the enclosed map titled "Proposed Changes For Permit Amendment" PCS Phosphate Company, Inc. dated November 29, 1999. 4 DJSTkJRBED HERBACEOUS ASSEMBLAGE (DH) 5 DISTURBED SHRUB — SCRUB ASSEMBLAGE (SS) 7 HARDWOOD FOREST (HF) 8 MIXED PIKE — HARDWOOD FOREST (MF) 12 PONDS (PO) WETLAND WITHIN PERMIT AMENDMENT AREA UPLAND WITHIN PERMIT AMENDMENT AREA CANALS PROJECT AREA BOUNDARY ALTERNATIVE E INDEPENDENT OF PROJECT AREA BOUNDARY FUTURE N & S RAILWAY 100' WIDE W-1 m PROPOSED CHANCES FOR PERMIT AMENDMENT PCS PHOSPHATE COMPANY, INC.

Subject: PCS Phosphate 12-31-99 Modification Request (Permit #07-01 Beaufort Co.) Date: Fri, 14 Jan 2000 11:02:04 -0500 From: Floyd Williams <Floyd.Williams@ncmail.net> To: Tracy. Davis @ncmail.net, Judy.Wehner@ncmail.net, Tony.Sample@ncmail.net Tracy: on 1-6-00 I made a visit to PCS Phosphate to make a field review of the three modification request in the December 31, 1999 letter from Jeff Furness to Charles Gardner. I met in the mine office with Mike Breza, Web Walker, Jeff Furness and Tex Gilmore and then a field inspection was made regarding the modification request. Following I will list the modifications and my comments after each listed modification: 1. Request approval to allow the placementof a limited amount of dredge spoil into the R-6 gypsum/clay blend reclamation area. This request would allow PCS to utilize the R-6 area during repairs to the dredge land booster pump or land discharge pipe and would also allow them to cap the R-6 area with dredge sweepings of silty material during the final dredge cut in the 240 acre block (northwest corner of EIS Alternative E). I do not see any problems with this modification request. 2. Request to relocate the area that is being utilized to clarify water from the mine area. The current clarification lake will need to be eliminated when prestripping on the NCPC tract begins in early 2000.The proposal is to pump water from the nime area to the southern half of the R--3 blend reclamation area and to the center of R-2 blend reclamation area . I do not see any problem with this modification request. 3. Request to clear 2 acres of land near the mine construction entrance to provide an access road to re-route a power line. This work must be accomplished in the very near future as part of the mine advance,I discussed this with Charles (You were out of the office) and we agreed to give PCS verbal approval to commence this activity. If you have any questions, please feel free to give me a call.

Box 27687 Raleigh, North Carolina 27611 Dear Mr. Gardner: RECENED I.Al 3 .00 DIV. iANDRM. PCS Phosphate requests approval of three modifications to Mine Permit 7-1. These modifications are outlined in the paragraphs below. As you are aware, PCS Phosphate Mine Permit 7-1 was modified to allow for dredging the upper overburden on 240 acres in the northwest corner of EIS Alternative E. The dredging operation began in July and is continuing. We request approval of a mine permit modification to allow the placement of a limited amount of dredge spoil into the R-6 gypsum/clay blend reclamation area. There are two scenarios when this would occur. The first is when repair work is required to either the dredge land booster pump or land discharge pipeline. A Y-valve in the dredge spoil pipeline ahead of the booster pump would be used to divert dredge spoil into R-6 when repairs are needed. The second scenario is to cap the R-6 area with the dredge sweepings, which is the silty material in the final dredge cut. The R-6 reclamation area will be capped at grade, which is approximately +15 msl. The second modification is to relocate the area that we use to clarify water from the mine area. Our current clarification lake is scheduled to be eliminated when we begin prestripping on the NCPC Tract early next year. We propose to pump water from the mine area to the southern half of the R-3 blend reclamation area to allow the turbidity to be reduced, and then discharge it out an NPDES permitted outfall. A 5-foot freeboard would be maintained at all times between the water level and the top of the R-3 dike. Water levels in the R-3 dike are still being monitored weekly using piezometers, as called for in the Approval to Impound for the R-3 dike. N . IV The third modification request is to clear 2 acres of land near our mine entrance to create an access road and re-route a power line. This acreage is currently within Mine Permit 7-1, however it has not previously been shown as "affected land”. The location of this activity is shown on the two drawings enclosed with this letter, one of which shows the sediment and erosion control measures to be utilized during the work. Enclosed is a check in the amount of $500.00 to cover the permit modification fee. If you have any questions regarding these requests, please call me at (252) 322-8249, or e-mail me at J fumess @pcsphosphate. com. Sincerely, 4 J ey .

These reductions and additions are illustrated in the enclosed map titled "Proposed Changes For Permit Amendment" PCS Phosphate Company, Inc. dated November 29, 1999. This proposal shall be reviewed for the applicability of other actions by North Carolina agencies such as: a. The issuance of a Water Quality Certification under Section 401 of the Clean Water Act by the North Carolina Division of Water Quality NCDWQ). b. The issuance of a permit to dredge and/or fill under North Carolina General Statute 113-229 by the North Carolina Division of Coastal Management (NCDCM). c. The issuance of a permit under the North Carolina Coastal Area Management Act (CAMA) by the North Carolina Division of Coastal Management (NCDCM) or their delegates. d. The issuance of an easement to fill or otherwise occupy State-owned submerged land under North Carolina General Statute 143-341(4), 146-6, 146-11, and 146-12 by the North Carolina Department of Administration (NCDA) and the North Carolina Council of State. e. The approval of an Erosion and Sedimentation Control Plan by the Land Quality Section, North Carolina Division of Land Resources (NCDLR), pursuant to the State Sedimentation Pollution Control Act of 1973 (NC G.S. 113 A-50-66). The requested Department of the Army (DA) permit will be denied if any required State or local authorization and/or certification is denied. No DA permit will be issued until a State coordinated viewpoint is received and reviewed by this agency. Recipients of this notice are encouraged to furnish comments on factors of concern represented by the above agencies directly to the respective agency, with a copy furnished to the Corps of Engineers. This public notice revision is being considered pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this revision. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this worksite is not a registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is 1192 otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer, based on available information, is not aware that the proposed activity will affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. r Cl Generally, the decision whether to issue this Department of the Army (DA) permit will not be made until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The NCDWQ considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the DA permit serves as application to the NCDWQ for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Water Quality (NCDWQ), Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Water Quality (NCDWQ), Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before January 7, 2000, Attention: Mr. John Dorney.

The Approved Area Of Work Includes All Of Alternative E Except That Bottomland Hardwoods Located In Mine Block 20 Are Excluded. The Original Public Notice Was Issued On August 1, 1988. PCS Phosphate Has Revised The Proposal To: Mae -an lA", 1kKG3 "Ur1rN M-0 1LiZ6)C0"1 b. DELETE THE SOUTHWESTERN CORNER OF ALTERNATIVE E (EXCEPT FOR 1.1 ACRES NEEDED TO ACCOMMODATE FUTURE RAILROAD LOCATION). c. INCREASE THE WIDTH OF THE CENTRAL PORTION OF ALTERNATIVE E. The following description of work is taken from data provided by the applicant in a letter dated October 13, 1999. The proposed permit modification would change the boundaries of the approved area of work to include 17.7 fewer acres of wetlands and would reduce wetland mitigation requirements by 36.5 acres. The enclosed map shows the location and proposed changes to the original permitted area. The report reflects the recent collection and analysis of 1999 biotic communities data as requested by the Wilmington district Corps of Engineers. The proposal is to reduce the wetland impacts for the proposal area from 162.3 acres to 144.6 acres and to decrease the wetland mitigation from 324.6 acres to 288.1 acres. Additionally the proposal is to increase the upland impacts from 57.7 acres to 111.5 acres within the proposal area. These reductions and additions are illustrated in the enclosed map titled "Proposed Changes For Permit Amendment" PCS Phosphate Company, Inc. dated November 29, 1999. 1'-k'V4-7 PCS Phosphate AURORA PCS PHOSPHATE COMPANY, INC.

PCS Phosphate - Mine Site Reclamation Actual Reclamation for the second half of 1999 (July 1999 — December 1999) R-1 Continued monitoring of tree growth in this area was done. Dr. Steve Broome is evaluating the growth for reference as additional areas are planted. R-2 Approximately 35 acres were sprayed for weed control, chopped to cut down vegetation, disk harrowed and planted. The cover crop that was planted consisted of winter rye with ladino clover, sweet clover, and alfalfa. Tree growth monitoring continued for comparison with the tree growth in the R-1 area. R-3 Water levels were controlled using an outlet valve that discharges into the 007 outfall canal. Water quality continued to be monitored. Approximately 240 acres were sprayed for weed control, chopped to cut down vegetation, disk harrowed and planted. The cover crop that was planted was the same as that planted in R-2, consisting of winter rye with ladino clover, sweet clover, and alfalfa. Actual Reclamation for the second half of 1999 (July 1999 — December 1999) CONTINUA) R-4 Water levels of the existing ponded area were controlled using the pumps located in R-4. Water quality continued to be monitored as the water was transferred to R-3. This area continues to dry and consolidate. R-5 Water levels were drawn down and controlled using the pump installed in R-5. Water quality monitoring continued as the water was transferred to R-4. This area continued to dry and consolidate. R-b Sand tailings continued to be discharged into this area during this period. R-7 Bucket wheel spoil, blend, and occasionally sand tailings water was discharged into this area during this period. RIPb Reclamation of Gypsum Stack 2 was started. Approximately 400,000 cubic yards of gypsum were moved during this period. Some initial shaping of the outer slopes was also done. Whitehurst Creek Continued monitoring of vegetation growth and water levels were done in this area. Preparations to plant the upland area around Whitehurst Creek in the spring were done. Charles Tract Continued monitoring of tree growth and water levels were done in Clay Ponds 3, 4A, 5A, and 5B. Planned Reclamation for the first half of 2000 (January 2000 --- June 2000) R-1 Continued motoring of tree growth in this area is planned. Dr. Broome will be evaluating the growth for reference as additional areas are planted. R-2 The ditches are to be cleaned out in this area to facilitate continued drying and consolidation. An additional 95 acres are to be chopped and stomped to firm up the surface. A plot of tree saplings is to be planted in the southwest corner. This plot should consist of cottonwood, green ash, sycamore, and sweetgum trees. Tree growth monitoring will continue for comparison with the tree growth in the R-1 area. Water quality will continue to be monitored. R-3 The ditches are to be cleaned out and extended in this area to facilitate continued drying and consolidation. An additional 135 acres are to be chopped and stomped to firm up the surface. Two plots of saplings are to be planted, one in the northwest corner and one within the central portion that has an established cover crop. These plots should consist of cottonwood, green ash, sycamore, and sweetgum trees. Additionally a stand of red cedar and longleaf pines are to be planted along the R-3 l R-1 dike. Water quality will continue to be monitored. Planned Reclamation for the first half of 2000 (January 2000 — June 2000) CONTINUED R-4 Water levels of the existing ponded area will continue to be controlled using the pumps located in R-4. Water quality will be monitored as the water is transferred to R-3. Some ditching will be done to assist the area dry and consolidate. Some chopping and stomping to firm up the surface is planned. R-5 Water levels of the existing ponded area will continue to be controlled using the pumps located in R-5. Water quality will be monitored as the water is transferred to R-4. This area will continue to dry and consolidate. R-6 Sand tailings will continue to be placed along the East Side of R-6. Process water from R-7 will continue to be transferred through R-6. This area will continue to dry and consolidate around the inactive areas of the perimeter. R-7 Bucket wheel spoil, blend, and occasionally sand tailings water will continue to be placed in this area during the first half of 2000. G-2 Reclamation of Gypsum Stack 2 will continue. Approximately 450,000 cubic yards of gypsum is planned to be moved during this period. Some shaping of the outer slopes will continue. Whitehurst Creek Tree planting is planned in the upland area surrounding Whitehurst Creek. There are approximately 50 acres that have been identified for this planting. Species to be planted include sweetgum, sycamore, green ash, and lobloIly pine. Continued monitoring of vegetation growth and water levels will be done in this area. Charles Tract Continued monitoring of vegetation growth and water levels will be done in this area. Preliminary planning work will be done for the construction of the final outfall which will establish drainage for the remaining ponds.
