Tonia had indicated your preference (and ours) to eventually take over those service areas, and to limit any future expansions to west of I-77. It's come to our attention that a developer is, or is planning to, initiate conversations with Aqua NC (Heater Utilities) to serve a future subdivision located on Transco Road off Langtree Road, just to the east of I-77. This includes both water and wastewater service. Due to other large scale projects recently approved by our board, adequately sized water and sewer lines will be constructed within a reasonable distance from this future subdivision. I believe the new lines should be scheduled'for completion before this subdivision would require service. Given that we will be taking over private sewer systems at some future time, we quite frankly do not want new ones to be added within our service area, particularly in places that we're in a position to serve in the very near future. Based on your previous meetings with the Town, Tonia and I are assuming you might hold the same opinion. We're hoping that the approval of the other large projects in the area and the more immediately available water/sewer will cause him to reconsider looking to Aqua NC . But in case that doesn't happen, I'd like to see what, if anything, we can do to keep him from providing private service. I appreciate your help, and look forward to talking about this further either by phone or e-mail. Thanks, Allison Kraft. P.E.

It will be good to work with you again. The agreement with Catawba County is very near being signed. We have just sent a final draft to them for review. It will be about 18 - 24 months to have the system in operation. Catawba County and Mooresville are working diligently together to complete this project and to begin to eliminate the smaller discharges into Lake Norman which will provide a much better alternative for disposal of that wastewater. Also, the Town of Mooresville has begun moving beyond Oak Tree Road on the Brawley School Road Peninsula with water and sewer as requested by residents and businesses. I think that will continue to occur as development seems to be moving more in that area. Our Water and Sewer Master Plans are near completion by Black and Veatch Engineers. This plan is looking at a service area through 2025 that encompasses all areas around Mooresville from the current Town limits to the eastern Iredell and Rowan County line; the southern Iredell and Mecklenburg County lines; western Iredell County line and Lake Norman; the northern Iredell County area between Mooresville and Troutman. The Town of Mooresville is negotiating with the Town of Troutman to provide water and sewer to them. Also, we have had discussions with Martin Lashua of the Carolina Water Company to provide water for them on the Brawley School Peninsula from McKendree Road to Lake Norman. Both of these areas are included in our master plans. As you may or may not be aware, the Town of Mooresville has a large pump station and 24" to 42" trunk lines under design, with CDM Engineers, for the Forest City development to the southeast of the Hwy 801 and Hwy 150 intersection. When completed, these facilities will eliminate about five existing older pump stations on the western side of Mooresville. This will help to eliminate some of the spills that occur. This area is included in our master plans. Mooresville also has a large pumping station and trunk lines under design with Black and Veatch Engineers to service the area south of Mooresville to the Mecklenburg County line. This area is included in our master plans also. Mooresville has a new 12 MGD water plant under construction which will replace our current 1962 water treatment plant. In addition, Mooresville has entered into a contract with CH2MHILL Engineers to provide the PER and EA for the expansion of the Town's 5.2 MGD wastewater treatment facility to a 15 MGD facility. This project also is included in our master plan. This is probably a little more information than you asked for, but I wanted to give you a look at the big picture for Mooresville now and in the future. I believe that it will help you to see what issues Mooresville will be seeking guidance from your agency on. 1 of 2 11/8/2005 1 l :40 AM RE: question about Catawba County We look forward to continuing to work with you on these complex issues.

Catawba County has searched for ways to provide the area with sewer since the 1980s, but building its own plant proved unpopular with residents, who did not want a plant to discharge into the lake, said Barry Edwards, Catawba County director of utilities and engineering. Seven discharges from small, mostly private sewer plants are already in that area, Edwards said. "We are very uncomfortable having any more discharges," he said. "We feel it needs to be handled in a more regional way." The county thought of connecting with Mooresville because the town is building a water -line connection with the city of Hickory. (The water line will be attached to the N.C. 150 bridge) The idea is attractive because the town's treated wastewater is discharged into the Rocky River, a moving body of water, not the lake, Edwards said. "They are the nearest connection we can make with a governmental body that we feel oversees discharges in a manner we would like to see," Edwards said. The two governments did enough preliminary work to determine that the sewer connection would be feasible. Mooresville Town Engineer Richard McMillan said the town has enough surplus capacity to sell some to Catawba County. "We've been very careful to make sure we have taken care of Mooresville 2 of 3 10/5/2005 9:36 AM [Fwd: [Fwd: [Fwd: FW: Wastewater Update]]] first and foremost," he said. On Tuesday, the Mooresville Board of Commissioners voted to pursue further negotiations with Catawba County. No contract has been drawn, but the county would likely purchase plant capacity from the town, on a per -thousand -gallons -a -day basis, Mooresville Town Manager Rick McLean told the board. Extending sewer lines to Catawba County would also open up the N.C. 150 corridor to municipal sewer, and the town would likely get new Iredell County customers. Residents of that area are served either by septic tanks or private sewer companies. Negotiations between the two governments will likely center on the cost of the lines, Edwards said. He hopes to have a deal to take to the Catawba County board by December. Mary Lou Lawson, a member of the Mooresville -South Iredell Chamber of Commerce's Lake Norman Preservation Committee, told the Mooresville commissioners the connection would be a good environmental decision. "We would like to protect future water quality," she said. Pam Carter, a Catawba County resident, also said she liked the idea of a connection. "It's just one more sewer plant that's not going into the lake," she said. "It should have been done quite a while ago."

Steve has indicated in the email below that " those areas do present a fall hazard, I do not think our employees should use this walkway or go on top of the tank where there is no standard guard railing until such time as fall protection meeting the OSHA regulation is provided. " Also based on comments that vandalism continues at the plant we need to have the permittee file police reports for each occurrence. I do not feel we need to consider remission for any violation, should violations occur, if the permittee claims vandalism and a police report is not provided. I did not see in the pictures if NO TRESPASSING of KEEP OUT signs were posted. If appropriate signs has not been posted I would direct the permittee to do so. Please keep Steve and I informed on your progress in this area Good Luck. Steve Kaasa wrote: Donna and Rex; Donna, thank you for sending me your concerns of your safety at this package plant. The concerns you enumerate are no safety railing around the top of the plant with an attendant fall hazard, no grating on the top of the aeration basin thereby constituting a fall hazard into the tank, and fencing that does not go all the way around the plant thereby constituting a general security problem. I will address the fall hazard issue, but will not address the fence requirements as this is more of a security issue than a safety issue. After reviewing the pictures you sent of this plant, I do have some concerns about our employees accessing parts of this plant. It appears from the pictures that access to the operating parts of the plant is gained by the wooden plank walkway. In its current condition, this walkway does not appear to meet the OSHA regulation for protection of open -sided floors, platforms or runways (29CFR1910.23). This walkway should, at a minimum, have a standard railing, as defined by 1910.23(e), along both sides of the walkway length. It is unclear from the 2005 picture (0-Berkley Oaks 005) whether all of the walkway is secured to the supporting timbers, but a portion of the walkway does not appear to be secured as a plank end is shown curling up. This curled plank end appears to constitute a trip hazard. Once access is gained to the top of the plant via the walkway, our employees may be further exposed to a fall hazard near the sampler equipment along the rear edge of the plant. If the sampler equipment is approximately three feet tall, then, from picture 2-Berkley Oaks2004-1, the drop to grade from this end of the plant appears to be approximately ten feet or more. This plant presents a fall hazard from the unguarded elevated sides of the tank and a fall hazard due to the lack of guard railing for the access walkway. As those areas do present a fall hazard, I do not think our employees should use this walkway or go on top of the tank where there is no standard guard railing until such time as fall protection meeting the OSHA regulation is provided. If you have any questions, please let me know.

Important SOC/JOC or Compliance Schedule dates: This facility is neither under an SOC nor is one being requested at this time. 4. Alternative analysis evaluation: As a result of litigation in the spring/summer of 2003, Hydraulics was required to reapply for an NPDES permit since an Administrative Law Judge (ALJ) ruled that procedural errors in the 1996 and 2000 NPDES permits made them invalid. Hydraulics chose to start the application process over again in lieu of appealing the ALJ's decision to Superior Court. Since they were in essence, starting from scratch, Hydraulics began the process by evaluating 10 different alternatives for wastewater disposal of up to 300,000 gpd of domestic and commercial strength wastewater (100,000 gpd of residential flow and 200,000 gpd of commercial flow). It was assumed in the Alternatives Analysis that the existing Pier 16 WWTP would be converted to a pump station, and all flow directed to the Hwy. 150 WWTP. It was also assumed that the entire acreage evaluated for non - discharge disposal alternatives could be hydraulically loaded at a 1 inch/week rate. This rate would produce a wetted area of z 26 acres for each 100,000 gpd of loading. Given these parameters, the various alternatives for wastewater disposal as evaluated by Hydraulics are as follows: 1. Construct conventional septic tank systems for 238 homes (up to 100,000 gpd), and one large cluster septic tank system for the remaining projected flow of 200,000 gpd. The existing Hwy. 150 WWTP would be used for pretreatment. Present Value Cost (PVC) = $18,3319,662* 2. Construct conventional septic tank systems for 238 homes (up to 100,000 gpd), and use an expanded Hwy. 150 WWTP for the remaining projected flow of 200,000 gpd. PVC = $999279494* 3. Construct conventional septic tank systems for 238 homes (up to 100,000 gpd), and construct a surface drip irrigation WWT system for the remaining projected flow of 200,000 gpd. The existing Hwy. 150 WWTP would be used for pretreatment. PVC = $179949,613 * 4. Construct a conventional septic tank systems for 238 homes (up to 100,000 gpd), and utilize spray irrigation for the remaining 200,000 gpd of projected flow. The existing Hwy. 150 WWTP would be used for pretreatment. PVC = $19,527,083* Page Four 5. Construct a 100,000 gpd single family surface drip irrigation WWT system for 238 homes and one large cluster subsurface drip system for the remaining projected flow of 200,000 gpd. PVC = $18,422,100* 6. Construct one surface drip system utilizing the Hwy. 150 WWTP for pretreatment for the entire 300,000 gpd of projected wastewater flow. PVC = $16,128,010* 7. Discharge the entire 300,000 gpd from an expanded Hwy. 150 WWTP. PVC = $6,4769591 * 8. Discharge the entire 300,000 gpd from the (expanded) Hwy. 150 WWTP as reclaimed wastewater (assumes effluent has been treated to reuse quality). PVC = $113301,183* 9. Discharge the entire flow of 300,000 gpd to the Town of Mooresville WWTP. PVC = $13,693,851 * 10. 100,000 gpd conventional septic tank systems for 238 homes, and the discharge of the remaining 200,000 gpd to the Town of Mooresville WWTP. PVC = $15,200,675 * * DWQ guidance requires that the Present Value Cost (PVC) of all the above alternatives be calculated over a 20-year period. Typically, the recommended alternative has been the one with the lowest PVC, however, environmental factors must be given equal weight as economic factors. In conducting the Alternatives Analysis, the permittee used a Decision Analysis (DA) process that weighed each proposed alternative against the needs of the community. In this process, community objectives were identified in order to address wastewater disposal options. The results of this DA process found that: 1. The use of septic tanks would pose the greatest public health risk, and pose the greatest risk to the environment. 2. The alternative of discharging the entire 300,000 gpd of wastewater back to the Town of Mooresville was identified as posing the least environmental risk. 3. The discharge from the Hwy. 150 WWTP was found to provide the greatest, overall value, and best meets community objectives because it lowers the cost to customers for wastewater treatment and it offers the most economic growth for the community. This alternative also was identified as the most economical of all the selected alternatives. Page Five PART IV - EVALUATION AND RECOMMENDATIONS The permittee, Hydraulics, Inc., has requested issuance of the subject Permit with no modifications. The WWTP is currently serving the River Park apartment complex and associate out - parcels of the River Park development. As a result of litigation in 2003 by the Catawba RiverKeeper and subsequent Public Hearing, an ALJ ruled that the NPDES permits issued for this facility in 1996 and 2000 were invalid due to procedural errors. Although the ALJ's decision was upheld by the NPDES Committee, the Committee did not support the Findings of Fact and Conclusions of Law and gave the permittee one year to apply for and obtain a new NPDES permit. In applying for the new permit, Hydraulics submitted a detailed Alternatives Analysis and Dilution Study in which an attempt was made to model the receiving waters and determine the amount of dilution that was present. The Dilution Study also provided contradictory scientific evidence that some of the allegations made in the Hearing were unsupported by fact. These include: 1. Data showed that air is entrapped in the outfall line resulting in a large boil on the lake surface. The air causes the effluent to rise when it is discharged, and thus, any reduction in the DO in the lower water of Lake Norman cannot be attributed to the Hwy. 150 plant effluent. 2. The wind is the primary effect on the direction of the current in the vicinity of the outfall. In larger lakes, water moves at an angle to the wind due to the earths rotation, thus the currents in Lake Norman at the vicinity of the outfall are heavily influenced by wind rather than the release from the upstream Lookout Shoals dam. 3. Under the conditions of the dye study, the intake at the nearby Marshall Steam Plant was shown to not influence the Hwy. 150 WWTP's dilution nor did it set up localized currents that impacted the plant's discharge, therefore, long term average withdrawals from the Marshall Plant were not expected to negatively impact the dilution available to the Hwy. 150 plant. 4. For the majority of the surface measurements, no dye was detected, therefore, the Hwy. 150 WWTP effluent is not impacting water in Lake Norman used by boaters, skiers, and swimmers. What was not satisfactorily proven in the dye study was that the actual dilution rate is higher than the dilution rate used in the study. Since the wastewater flow rate used in the dye study (212 gpm at a continuous flow) was less than the WWTP plant's actual flow rate of 360 gpm discharged as a batch flow, we question the conclusion that the actual dilution rate will be higher than the dye study rate because the higher (batch) pumping rate has higher dilution due to higher velocities and momentum of the discharge. Although the staff of this Office is in agreement that there should be more than adequate dilution present within a short distance of the discharge point, the fact that the dye study was not performed using identical flow rates of the WWTP, we question the claim that at higher flow rates the dilution will also be greater (based on the criteria used in the dye study). Page Six Subsequent to the Public Hearing, Hydraulics purchased Heater Utilities who owned the nearby Pier 16 Marina WWTP (NC0074535). It is Hydraulic's intention (pending reissuance of this permit) to eliminate the existing WWTP and convert it into a pump station. All wastewater would then be pumped to the Hwy. 150 WWTP. It is our understanding that it is the intention of Hydraulics to make this connection once the subject permit has been reissued. In February 2004, an email notice was received from Michael Myers with Hydraulics advising that the corporate name has been changed from Hydraulics to AquaSource, NC. To -date, however, no official request for a name change has been received from the company. Prior to issuance of the subject permit, the appropriate permittee should be determined, and if necessary, the appropriate paperwork should be submitted to effectively change the owner's name in this application request. There continues to be a significant amount of interest in the renewal of this permit by the Catawba River Keeper and the citizens living in the adjacent Spring Shores development. This Office has also received several complaints of odor from this facility, however, the primary complainants live at least 1/3 mile from the WWTP. The residents who live much closer to the plant, have rarely complained of migrant plant odors in the past several months. This Office anticipates a Public Meeting will be held on the issuance of this permit. Pending a final technical review of the application and supporting documents by the NPDES Unit, and concurrence that the existing discharge is capable of complying with the effluent limitations that will protect the water quality of the receiving stream, it is recommended that the request to issue the NPDES permit be approved. 7 27 ©f Water Quality Vgional Supervisor Date h:NdsrNdsro4\hwy 150.dsr ,^ J Mooresville -South Iredell � Chamber of Commerce 149 E. Iredell Avenue • P.O. Box 628 • Mooresville, NC 28115 • (704) 664-389r FAX (704) 664-2549 June 23, 2004 FF OFFICE OF THE I Secretary Bill Ross North Carolina Department of JUL 6 innd Environmental and Natural Resources jy 1601 Mail Service Center Raleigh, NC 27699.1601 11NO .;_nfv,.,_: Dear Secretary Ross: Based on the following points, the Mooresville -South Iredell Chamber of Commerce opposes any expansion for the Aqua, NC Saer.ge Treatment Plant 3t the Highway 150 bridge at Lake Norman in southwest Iredell County: • Lake Norman is a significant factor in the quality of life for the Mooresville -South Iredell area. As such, the lake serves as an economic development asset for this area, serving as a magnet attracting residents and businesses. With this in mind, the protection of the water quality in the lake is of paramount importance. The leadership of our Chamber of Commerce considers any expansion of the Aqua, NC plant a significant threat to the long-term water quality of Lake Norman. Last year, Aqua, NC's permit for 100,000 GPD was rescinded by DENR. The courts later granted Aqua, NC the ability to continue to operate; however, they had to reapply for a new permit within one year, which they did in December. The Aqua, NC stated goals are for an expansion to 300,000 GPD with a longer term vision to expand to 1,000,000 GPD across county lines. The 300,000 GPD would be ten times larger than any other plant on the lake and larger than the combined total of all fourteen plants currently on Lake Norman. • All treatment plants have a certain frequency of operational failures which result in untreated waste being spilled directly into this important body of water, which provides drinking water to many communities. We believe there are other options that do not include discharge into the lake, which are preferable to the option under consideration. Based on these points, the Mooresville -South Iredell Chamber of Commerce respectfully requests the DENR oppose any expansion of the Aqua, NC Sewage Treatment Plant at the Highway 150 bridge at Lake Norman.

It is my understanding that this facility currently has an application to expand pending approval by your office. Since the County's initial comment on the expansion of this project there has been a change in the way we deal with facilities of this type. On May 4, 2004, the Iredell County Board of Commissioners amended the Zoning Ordinance to require that facilities of this type, in this particular zoning district, obtain a Special Use Permit before the construction of an initial operation, or prior to the expansion of an existing facility. In addition to this change the Board has also directed the Planning Department to draft changes to the design standards for non -governmental sewage treatment plants. The intent of this amendment would be to provide a higher level of protection to adjacent, residentially zoned properties. Attached please find a copy of the standards required in the Zoning Ordinance and in the Iredell County Code. If I can be of any further assistance please contact me at (704) 878- 3050. Sincerely, Joel Mashburn County Manager SR 48. Marinas, Commercial In the R-A and R-R Districts Marinas permitted as Special Uses shall meet the following minimum standards: a.

(a) In those situations where a special use permit, planned residential development permit or final subdivision plat approval is required, the applicant for such a permit or plat approval shall demonstrate prior to the issuance of the same that the design standards as set out belo«- in this subsection will be met. Where no such permit or plat approval is required as part of the development process, the owner of the wastewater disposal system shall demonstrate prior to the issuance of a building permit that the design standards as set out below in this subsection will be met: !1; Except for the collection lines, no part of a wastewater disposal system shall be located in a floodplain unless the facility is protected from the 100-year flood, nor on lands whose soils are not suitable for the construction of such a facility. To the greatest extent practicable, the facility shall be located on the same presubdivision tract as the units intended to be served by the facility. (2) Wastewater disposal systems shall be sited so as to minimize any potential adverse effects on adjacent or nearby property owners that might be caused by odor during a period of failure as well as normal operation, or by noise from the operation of the facility. Notwithstanding the above and except for the collection lines, no part of such facility shall be located within one hundred fifty (150) feet from any existing residen- tial structure and within forty-five (45) feet of any property line adjacent to the ound -portions of -such facilities shall be fully proposed development. All abovegr screened by a buffer strip as defined in section 41.6 of Appendix A. Snpp. No. 3 840 WASTEWATER § 14-30 (3) The location of any wastewater disposal system, shall be clearly designated on the preliminary sketch plan and final subdivision plat, on any plans for planned residen- tial development, or on the site plan of any other proposed development. (4) Wastewater disposal systems shall be so designed and situated as to pose no signifi- cant injury to the public health or safety. (5) Wastewater disposal systems shall be designed to allow connection with a municipal sewer system in the event that one was provided for the drainage basin in which the development is located. At such time as a municipal sewer system is available in the area, the Iredell County Health Department shall require that within twelve (12) months the wastewater disposal plant be disconnected and/or removed by the owner and the connectors connected to the municipally owned system, and in such event no damages shall be due the owner. (6) Wastewater disposal systems except septic tanks shall be designed to provide for convenient sampling of final effluent after the chlorination point and prior to dis- charge. (b) The owner of a wastewater disposal system shall demonstrate prior to the issuance of a building permit that the following design standards are met: (1) Wastewater disposal systems shall be designed so that there will be a source of permanent, on -site emergency standby power. In the alternative a solenoid operated valve installed in the water supply system that will shut off water to all units in the event of electrical failure at the waste disposal facility may be allowed in lieu of standby power. Nothing in this subsection shall be interpreted as a substitute for any requirements of the state public utilities commission or the state department of en- vironment, health, and natural resources. (2) Wastewater disposal systems shall be designed to have at least a twenty year useful life. The applicant shall furnish a list of anticipated major repairs and the costs of those repairs for the useful life of the facility. (3) Wastewater disposal systems shall be designed using state of the art technology with materials which are reasonably capable of carrying out the functions for which they are designed for a reasonable length of time. Following the construction of the system a professional engineer licensed by the state shall certify that the system was built as designed.

(a) Wastewater disposal systems shall be monitored regularly by an operator properly certified by the state to ensure that the facility is operating properly and is achieving the quality of treatment for which it is designed. The operator shall file, or cause to be filed, monthly monitoring reports with the county health department concerning such matters, at such times, and on such forms as the health department shall indicate. This monitoring requirement may be met in a manner other than personal inspection, as in computer read and communicated information to a central monitoring office, or the like, providing such a method is reliable. The Iredell County Health Department shall hire or contract with a certified operator to routinely inspect, monitor and sample any wastewater disposal system located in Iredell County and within the jurisdiction of this ordinance at any time but not less than once every other month. The health department shall notify the appropriate state agency if it has reason to believe that the facility may not be operating properly, or that a violation of state regulations has occurred. This notification shall be in addition to any penalties imposed by section 14-28. (b) Wastewater disposal systems shall be owned and operated only by a utility certified by the state public utilities commission. All operators shall demonstrate that they hold all li- censes, certificates and approvals required by the state department of environment, health, and natural resources to operate such facility. No facility shall be certified as complete until such time as an appropriate licensed operator for the facility is reported to the county as set out above. (c) Wastewater disposal systems shall be designed, operated and maintained so as to comply with all rules and regulations of the state public utilities commission, and the state department of environment, health, and natural resources that may be applicable to that facility. (Ord. of 10-29-85, § 5; Ord. of 10-2-90) Sec. 14-32. Insurability of operations. (a) Except as otherwise provided in this article, the owner of the wastewater disposal system shall furnish adequate security for the repair and replacement of major capital parts of the plant and its operation. Adequate security may be met by furnishing a line of credit from Supp. No. 3 842 WASTEWATER § 14-33 a lending institution operating within the state, or by furnishing an acceptable bond, or by depositing cash in the hands of a trustee acceptable to the county or by providing for the creation of a fund which will achieve the required amount within three year period. (b) The amount of security necessary to insure repair and replacement of major capital parts shall be equal to the major capital parts of the plant which could be reasonably antici- pated to need replacement during the life of the plant. Unless otherwise established, it shall be presumed that the costs of replacement of major capital parts shall be equal to ten thousand dollars ($10,000.00) (1985 dollars), or two hundred dollars ($200.00) (1985 dollars) per unit intended to be served, whichever is greatest. The owner shall not be required to provide security for repair, operation and major capital parts replacement until such time as the county has determined that the facility is completed. (c) Final plat approval or approval of a special use permit or planned unit development permit or any development intending to utilize a wastewater disposal system for waste treat- ment shall not be given until adequate security is provided to insure the completion of such a system. Similarly a certificate of compliance for any residential unit intended to be served by such a system shall not be given until security for the replacement and repair as required in this section is provided. (d) If the state public utilities commission does not allow or approve the owner of a system to provide security for construction or replacement of the system as set out in subsection (a), the board of commissioners, on application of the owner and upon being satisfied that the purpose of the security will be satisfied in another manner, may waive the prescribed security. (Ord. of 10-29-85, § 6; Ord. of 10-2-90) Sec. 14.33. Certificate of compliance. (a) No certificate of compliance shall be issued pursuant to this article for any develop- ment utilizing a wastewater disposal system until such a system has been completed and certified by an engineer, licensed by the state, to be in working order and capable of treating the wastes for the development that it is proposed to serve. Furthermore, no certificate of compliance shall be issued for any development utilizing a wastewater disposal system until the permit issuing authority for such certificate has determined that all the design standards set out above, all conditions of any special use permit, planned residential development permit, or preliminary or final site plan, as might be related to any aspect of the community waste- water disposal system, and such other provisions in this article as it may deem applicable as inferred from the timing of such provisions, (including but not limited to the insurability and reporting provisions) have been met. (b) The permit issuing authority for the certificate of compliance shall be the Iredell County Inspection Department.
