As included in the attached report,the co-permittee members discharged a total of 542,205 pounds of total nitrogen to the Neuse Estuary during calendar year 2006, about 48% of the permit limit of 1,137,171 pounds. In 2005 the Association discharged 566,627pounds,with a permitted limit of 1,137,171 pounds (or 50%or the permitted limit.) We are very proud of the accomplishments of the Association and the efforts made by our members to reduce nitrogen loading to the Neuse River Estuary. We hope that the enclosed report provides the detailed information that the Division needs. If you have any questions, or if you need any further information,please contact our Executive Director, Cindy Finan at 919/387-3478, Sincerely, - �I /• 4 vissu.• f ' Hayw !•d M. Phthisic ,?

The permit was issued to the Neuse River Compliance Association, a nonprofit association of 19 wastewater treatment facilities with permits to discharge treated wastewater into the Neuse River. All NPDES permitted dischargers over 0.5 MGD in the Neuse River Basin have received an annual mass limit for Total Nitrogen(TN)to meet a Total Maximum Daily Load (TMDL) established for the estuary. Each facility has a"transport factor" assigned to account for loss of TN in stream travel. Transport factors vary from 10% at the upper watershed, above Falls Lake Dam,to 100% for facilities discharging directly to the estuary. By multiplying the"end of pipe"discharge, where monitoring occurs,times the transport factor,results in estuary loading value. The State Statute and Administrative Rule include a provision that point sources can meet individual allocations of TN or they can voluntarily form an association for group compliance with their aggregate estuary allocation. The framework for compliance with these requirements includes the following provisions: In any calendar year, the Permittee shall be in compliance with the annual TN load limit in the permit if: a. The Permittee's annual TN load is less than or equal to the limit in the permit, or b. The Permittee is a co-permittee member of a group compliance association. All sampling,monitoring and monthly reporting requirements are included in the individual permits. The Division of Water Quality issued Permit No. NCC000001 to the Neuse River Compliance Association and its co-permittee Members, effective January 1, 2003— December 31, 2007. This permit applies only to Total Nitrogen. The Total Nitrogen limit in this permit is measured at the estuary and is the sum of co-permittee members total nitrogen estuary allocations. Co-permittee members,transport factors and individual allocations are listed in Appendix A of the permit. The Reporting Requirements of the Group Permit include: Year-End Report. No later than February 28, 2004 and each February 28th thereafter, the Association shall submit a year-end report to the Division. The report shall include, at a minimum,the following information for the previous calendar year: 3 1) for the period from January 1 through December 31 of the preceding year, a Discharge Monitoring Report of each co-permittee member's discharge and estuary TN loads and the Association's estuary TN load.; 2) a summary of changes in Association membership, including regionalization of discharges; 3) a detailed summary of all purchases, sales, trades, leases, and other transactions affecting the TN allocations of the Association or its Co- Permittee Members; 4) a description of the Association's TN control strategy for the preceding year and changes for the coming year; 5) a detailed summary of measures taken to control TN discharges; 6) an assessment of progress made, and; 7) a description of efforts planned for the upcoming calendar year(s). In compliance with the permit,the annual report for 2006 is as follows: Item 1. The Discharge Monitoring Report of each Co Permittee Member's Discharge and Estuary Loads and the Association's Estuary TN Load is attached. Co-permittee members discharged a total of 542,205 pounds of total nitrogen to the Neuse estuary on the basis of individual TN discharges and estuary transport factors established by the Division of Water Quality. The calculated estuary loading is substantially less than the permitted estuary allocation of 1,137,171 pounds(48%of permitted limit). The 1995 TN loading from the NRCA members was 1,784,130 pounds with a flow of 83.808 MGD. The 2006 numbers reflect an average flow of 102.970 MGD and a total loading of 542,205 pounds of TN at the estuary. The NRCA has added 3 new members since the original group reported their baseline loading in 1995. Still, their loading reported in 2006 would indicate that they have reduced the nitrogen loading from these point sources by 70%over the loading reported in 1995, even while flows have increased. Item 2. Summary of changes in Association membership, including regionalization of discharges: The only change to the Association's membership that was reflected in the NPDES permit in 2006 was the transfer of the City of Wake Forest's Smith Creek Plant (NC0064149)to the City of Raleigh. Additional changes that were experienced in 2006 that will be reflected in the modified permit in 2007 are: the transfer of the permit NC DHHS, John Umstead Hospital (NC0026824) to South Granville Water and Sewer Authority; the transfer of the Town of Zebulon's Little Creek WWTP (NC0079316) to the City of Raleigh; and the addition of the allocation from Jones Dairy Farm WWTP (NC0064149)to the allocation for the City of Raleigh's Smith Creek WWTP (NC0064149.) Additional issues regarding the permit modification have yet to be resolved. Additional details of regionalization are summarized,by facility,below: 4 • Town of Benson: The Town has partnered with Johnston Co. to take approximately 140,000 GPD from Four Oaks. City of Kinston: The new Kinston Regional Water Reclamation Facility(KRWRF) began discharging on August 23, 2006. The last day of flow from the old Peachtree Wastewater Treatment Plant was September 1, 2006. Item 3. Detailed summary of all purchases, sales, trades, leases and other transactions affecting the TN allocations of the Association or its Co Permittee members. South Granville Water and Sewer Authority(SGWSA) sold 3,668 lbs/yr. of estuary allocation to the Town of Clayton. SGWSA holds in reserve 2,445 lbs/yr. of estuary allocation. This amount is the remainder of the 6,113 lbs/yr. of TN purchased from Bay River MSD in 2003. Several short term lease agreements that have been entered into by NRCA members for 2006. At this time these leases are only for the year 2006. The transfers are reflected on the attached spreadsheet containing the data for the members for 2006. They are summarized as follows: The Town of Kenly has leased 3000 estuary pounds of nitrogen from Johnston Co. in order to allow them to comply with their allocation while they pursue an engineering review of their facility for possible improvements. Contentnea MSD has leased 5000 estuary pounds of nitrogen from Unifi-Kinston LLC in order to comply with their allocation while they are finishing work on their collection system. Correction of infiltration and inflow problems in the collection system should improve treatment at their wastewater treatment facility. MCAS Cherry Point has leased 10,000 estuary pounds of nitrogen from the NRCA while they pursue and upgrade to their treatment plant. It should be noted that while Cherry Point made this agreement and paid the association for the nitrogen in both 2005 and 2006, they were able to comply with their original allocation without this leased nitrogen. The NRCA is using the money from the lease agreement to pursue nitrogen removal projects in the Neuse Estuary. Item 4. Description of the Association's TN control strategy for the preceding year and changes for the coming year: The Association continues to monitor member's compliance with TN allocations and enforces against its members based on the following policy. The Operating Policy and Procedures Committee of the Association developed and recommended operating policies and procedures in May of 2003. The NRCA adopted the following policies and procedures on June 17, 2003. 5 "Assessment of Penalties Paid by Association for Noncompliance. The member(s) responsible for reporting violations or other violations not related to exceedence of the Association's group nitrogen allocation shall pay or share payment of the entire penalty. Incentives for Members to reduce their TN discharge and disincentives for exceeding their individual estuary allocation. The assessment for an individual member exceeding its estuary allocation shall be one-fourth of the Wetlands Restoration Fund amount for a member's first annual exceedence, one-half for the second annual exceedence, three-fourths for the third annual exceedence and 100%afterwards. This assessment shall apply for an exceedence of an individual allocation in the year(s) in which the Association is compliant with its allocation and also in years when it exceeds its allocation, however in years that the Association exceeds its allocation, any amount paid by the individual discharger as its share of the Association penalty shall be credited to the assessment. The assessment will be accounted for separately and made available to the member that paid it to use for the wastewater treatment plant improvements, provided that a plan for such improvements is presented to and approved by the NRCA as being reasonably designed to address the TN exceedence. The assessment will be repaid to the member once the project is completed and the member achieves compliance. There should be an annual progress check by the NRCA to ensure that the project remains on the approved schedule. The NRCA should retain 20%of the assessment paid by the member to cover administrative expenses. The amount of the assessment should be based on excess pounds delivered to the estuary by the discharger, not the excess pounds discharged at the end of the pipe, since the Neuse Rules were written and adopted to protect only the estuary from nitrogen overload. The assessment should not become effective until the year 2004. " In addition,the Bylaws of the Association allow the group to establish policies and procedures and establish a framework to encourage the transfer of TN allocation by members in a manner that is cost effective and that provides incentives for TN reduction that will be most beneficial to the Neuse Estuary. Several members have chosen to pay another member for a temporary lease of a portion of their total nitrogen allocation,to bring them into compliance rather than to risk facing enforcement from the Association. Only two members, the Town of Kenly and Contentnea MSD have negotiated lease agreements to bring them into compliance with their allocation. The Association believes that these members are taking adequate steps 6 to address nitrogen reduction at their plant at the current time. The MCAS Cherry Point, negotiated a lease agreement with the NRCA in order to become a member, and paid for 10,000 lbs of TN in 2006. In the end, the Base managed to make adjustments to their plant that allowed them to comply with their original allocation for 2005 and again in 2006. The money that was collected for this lease in 2005 has been earmarked for the Town of LaGrange to use to fund a reuse project at their facility. This project will effectively use the entire effluent flow to irrigate a nearby nursery during the warm months of the year. This should serve as a great help to the Neuse River,by removing this discharge from the river during warm months. The addition funds that were collected from the lease agreement in 2006 will be used to fund additional nitrogen removal projects to benefit the Neuse Estuary. Policy and/or rulemaking goals that should be pursued. (1) Point source/non-point source trading may be advantageous and should be pursued. (2) The association is still constantly reviewing and rewriting its bylaws. The Association's enforcement policy was originally based on the offset fees required to be paid to the Ecosystem Enhancement Program. While these fees are under review by the legislature,the association continues to revisit their enforcement policy in order to strengthen it in an effort to encourage members to treat to the lowest levels possible. Item S. Detailed summary of measures taken to control TN discharges: A summary from each member is provided below: Town of Apex: The Town is continuing with manipulation of ditch rotor motors (on/off) in the aerobic zones, creating more anoxic zones. Butner/SGWSA: Intermediate pump station operation was adjusted to minimize flow changes within the anaerobic and anoxic basin. Cary: The North Cary facility was designed to remove nutrients biologically without chemical addition. The nitrogen discharges to Crabtree Creek, a tributary to the Neuse River in the 50%transport zone. The town diverts flow to the reclaimed water system with use as much as 907,000 gallons per day in peak season and a minimum of 116,000 gallons in the non-peak. The South Cary facility was also designed to remove nutrients biologically without chemical addition. The plant discharges to Middle Creek, a tributary to the Neuse River, and diverts flow to a reclaimed water system with use as much as 260,000 gallons per day in peak season to a minimum of 80,000 gallons in the non-peak season. The town operates the water reuse program consisting of reclaimed water treatment, storage and distribution of treated and disinfected effluent. The distribution system includes dedicated reclaimed water piping and bulk transport of reclaimed water off plant premises by certified operators. This water is used for irrigation, in commercial 7 cooling towers, dust control, road bed aggregate compaction and other permitted non- discharge purposes. The tables below summarize the yearly net effect of this program as a diversion or offset of treated effluent not entering the Neuse River watershed.

During the last quarter of 2006 the filters were hydraulically loaded(2.5 to 3.0 gal./sq. ft.) The average TN concentration for the last quarter is 1.30 mg/1. The county sprayed 57.8 million gallons of effluent on reuse fields,keeping that loading from entering the Neuse River. Clayton: The town currently has a major BNR project underway that is 75%complete at a cost of$3.2 million. Contentnea MSD: The three towns that make up CMSD are working to control infiltration and inflow. This is a slow and expensive task for small towns. They have made major improvements to the collection system, however I&I is still a major priority. The board has been presented with a plan which includes an upgrade and expansion of this facility. A decision should be made in the next 6+months. During 2006, the facility experimented with"Kenaf'to assist in TN reduction. The regional office of DWQ was aware of this test and other facilities have used this product with some degree of success. The facility ran the study for 6 months using this product and determined that it was detrimental to the treatment process and did not accomplish any nitrogen removal. They discontinued the study in August of 2006. Goldsboro: The City of Goldsboro WRF used biological treatment control to reduce the amount of total nitrogen that is discharged from the plant into the Neuse River. The City also reduces the amount of total nitrogen that is discharged into the Neuse by using reuse water for irrigation at a hay farm and at the golf course, as well as a constructed wetlands polishing project, which is performing very well. Town of Kenly: The Town is utilizing various control measures that were recommended by their engineering firm and has been able to reduce their TN discharge by 28%despite a 10% increase in influent flow. The engineering firm that is assisting the town is currently working on an engineering study that will likely recommend automation of the treatment plant including the installation of timers on the aerators in the aeration basins. Kinston (Peachtree and Regional): The new Kinston Regional Water Reclamation Facility(KRWRF)began discharging on August 23, 2006. The last day of flow from the old Peachtree WWTP was September 1, 2006. The components of the new KRWRF are as follows: Primary Treatment- fine filter screening and grit removal; three trains of BNR with three methods of computer controlled oxygen input; three secondary clarifiers with individual RAS pumps and controls; four new denitrification filters with methanol feed and UV disinfection. City of New Bern: The City of New Bern began discharging into the Martin Marietta Quarry under permit#WQ0017635. The water was used to irrigate a sod farm. Approximately 13,013.20 pounds were applied to the land that did not enter the river. In August- 3,154.44 pounds were diverted, in September- 3,415.23 pounds, in October- 4,046.05 pounds and in November- 2,397.47 pounds. 9 City of Raleigh/Neuse River WWTP: During 2006, all six aeration basins and mixed liquor distribution channels were upgraded with new diffuser systems. In addition, testing was completed using sugar water as an alternative to methanol. Wilson WWTP: funding was obtained to extend the reclaimed water distribution pipe to Bridgestone Firestone (BF) and Bert Gillette Soccer Complex. BF will use reclaimed water in their cooling towers. This project should be completed by the end of the year. Additional spray areas for reclaimed water were added at Wedgewood Golf Course. A new BNR basin was put on line in February, 2006. The City continues to seek ways to improve operation of the BNR system and denitrifying filters to further reduce TN. Zebulon/City of Raleigh-Little Cr.: The facility continues to work to control the amount of TN discharged through proper operation of the facility. Unifi-Kinston, LLC: The operators continue to maintain an anoxic zone in the front basin to aid in denitrification. MCAS Cherry Point: The Base began construction of a$13 million plant upgrade to remove TN at the facility. Item 6: An assessment of progress made: We believe the numbers speak for themselves! Current members of the compliance association discharge the following flows and pounds of total nitrogen to the Neuse Estuary in the years shown: Year Total Flow Total Estimated (MGD) pounds TN to Estuary 1995 83.808 1,784,130 1996 85.675 1,741,492 1997 81.444 1,653,262 1998 93.442 1,387,717 1999 94.659 1,123,169 2000 92.582 1,056,202 2001 _ 86.818 907,381 2002 89.926 797,991 2003 107.463 711,398 2004 101.203 558,553 2005 101.757 566,627 2006 102.970 542,205 The Association is extremely proud of the efforts of its members in removing still more nitrogen from the Neuse this year and the removal rates that they have been able to achieve. We are pleased that one of our new members, MCAS Cherry Point, has been able to use their membership in the Association to assist them in making improvements in 10 their operations that have brought them into compliance with their original allocation. We have seen that the commitment, experience and knowledge of our members has helped the group to minimize nitrogen loading which we hope will further improve water quality in the Neuse River estuary in the future. Item 7: Description of efforts planned for the upcoming calendar year(s): The following details were provided by our members on their plans for 2006 and beyond. Apex: The town is continuing with manipulation of ditch rotor motors in the aerobic zones to create more anoxic zones. If the nitrogen levels rise too much, the town has plans to divert some of the flow to the City of Raleigh. Benson: The town will pursue a plant upgrade for flow in 2007. South Granville Water and Sewer Authority: The authority will continue to resolve hydraulic issues and to further investigate intermediate pump station operation-duration and sequencing. Cary: The Town of Cary commits itself to continued optimal performance of its two biological nutrient removal water reclamation facilities. Johnston Co.: The County plans to continue their filter optimization project. Clayton: The Town of Clayton plans to complete the current BNR project along with a reuse water system. Both systems should be completed by the end of the year. Contentnea MSD: CMSD plans to 1) Continue with I&I reduction. 2) Install denitrification filters and piping of their effluent to meet NCDWQ requirements for effluent channels. They will submit a grant application to the NCCWMTF to aid in the funding this project. 3) Continue with plant upgrade/expansion plans. Goldsboro: The City of Goldsboro WRF will continue the present strategies on the reduction of the total nitrogen at its water reclamation facility. Kenly: The Town of Kenly has retained the engineering service of O'Brien and Gere and anticipates completion of an engineering study by the summer of 2007. The town is required to submit this study to the NRCA and will proceed to implement the study's recommendations. Kinston: Approximately 83,000 pounds of TN was discharged from the two plants in 2006. The target discharge of TN for 2007 will be 63,000. The City's NPDES permit allows for 126,710 pounds, therefore, they hope to achieve a 50%reduction for 2007. A ten acre effluent(reuse water) spray field in currently under construction. Seventy more acres are planned for completion in late 2007-2008. 11 New Bern: The City of New Bern will continue to operate its land application/reuse program and will strive to improve operation. The effluent will be discharged into the Martin Marietta Quarry for reuse on Mackilwean Turf Farm. Raleigh/Neuse River WWTP: In 2007, the aeration blowers will be replaced and an automatic dissolved oxygen control system will be installed to better control dissolved oxygen levels in the aeration basins. Also, additional tertiary filtration will be installed. This additional filtration will reduce loading on the existing filters and provide for better denitrification before final discharge. City of Raleigh/Smith Creek: the Smith Creek WWTP is scheduled to be upgraded and expanded from 2.4 MGD to 3.0 MGD beginning in 2007. Upgrades that may have an impact on nitrogen performance include: aeration system modifications, additional tertiary filter capacity and the ability to divert flow to the Neuse River WWTP for flow equalization. Wilson: The City plans to upgrade the dissolved oxygen control process in the BNR system including installation of new DO probes to improve BNR efficiency. Construction to expand the reclaimed water system to Bridgestone Firestone and Bet Gillette Soccer Complex will begin in early summer. Zebulon/City of Raleigh- Little Cr.: The City is planning stages of expanding the reclaimed water system. The expansion will take reclaimed water to several industries in town and increase the system use up approximately 100,000 gallons per day. Unifi-Kinston, LLC: the facility will try to maintain anoxic zones in the front basin for denitrification. MCAS Cherry Point: The base will continue with construction of the TN removal system upgrade. The project should be complete in summer 2008. The NRCA was nominated for an EPA Blue Ribbon Water Quality Trading Award in January, 2007. We have included a copy of the nomination that was submitted at the conclusion of this report. The winning programs will be announced in May/June 2007. We believe that the reductions in nitrogen loading that have been eperienced by the NRCA are deserving of national attention! 12 TOTAL NITROGEN DISCHARGE MONITORING REPORT PAGE 1 OF4 • NEUSE RIVER COMPLIANCE ASSOCIATIONS ' YEAR-END REPORT FOR 2006 I 1 February 25, 2006 2006-JAN THROUGH HDEC - J I _ _ 1 NPDES PERMIT NO: NCC000001 END OF PIPE ESTUARY __ Permit 2006 Member TN Member TN' Temporary Original i Adjusted TN 2006 TN FACILITY NPDES Permit Fiowi Avg Flow Allocation Discharge Transport Lease Estuary 1 Allocation 2006 Discharge (MGD) (MOD) (lbs/Yr.)

The basin covers all or part of 19 counties and has a population of 1.3 million people. (See Figure 1.) The Neuse River Estuary is a shallow estuary that feeds directly into the Albemarle-Pamlico Sound system which is the United States' second largest estuarine complex and a key fisheries nursery for the mid-Atlantic coastal region.' The estuary has experienced major eutrophication issues since the early 1970's. The increased nutrient loading to the estuary has caused major algae blooms and fish kills. The publication of the book"And the Waters Turned to Blood"by Rodney Barker in 1997 brought considerable attention to the plight of the Neuse River Estuary. When initial research indicated that phosphorus was the problem, the State of North Carolina initiated a phosphorus detergent ban in 1987. Problems in the estuary continued and further research pointed the finger at nitrogen as the limiting factor. The management strategy for the Neuse River Estuary included a Total Maximum Daily Load (TMDL)that was adopted in 1999. Studies showed that a reduction of 30%was necessary in the Total Nitrogen loading, with a deadline of 2003. The point source dischargers in the basin were given an allocation of 1,640,000 pounds of Total Nitrogen in order to meet this reduction. There was no allocation reserved for new or expanding facilities. Allocations were given based on the permitted flows that existed in the permits in 1995. This caused a great inequity in the distribution of the Total Nitrogen allocations, ' Paerl,Hans W.,Lexia M.Valdes,Alan R.Joyner and Michael F.Pithier;University of North Carolina at Chapel Hill,Institute of Marine Science.

Due to the inequities caused by the distribution of the allocations, the "Neuse Rules"that were developed by the State, allowed for the formation of compliance groups by the major point source dischargers. The concept of the compliance group was to allow a group of dischargers to meet a collective limit, thus allowing them to pursue reduction strategies where the most benefit could be enjoyed at the lowest cost. In 1996, the General Assembly of the State of North Carolina appropriated 2 million dollars for the Lower Neuse Basin Association, to provide grants Page 3 of 16 to dischargers in the basin to help them pursue nitrogen reduction strategies at their plants, or to remove wastewater discharges from the river. From the members of the Lower Neuse Basin Association came an altruistic group of dischargers who became the Neuse River Compliance Association(NRCA). The NRCA is a non-profit, 501 c (3) organization. They worked with the State and were given the first permit issued to a compliance association in the United States in December, 2002. The members of the NRCA and their respective allocations are listed in the excerpt of the Annual Report for 2005 which is included in AppendixA. For clarification purposes, the members of the Lower Neuse Basin Association and the Neuse River Compliance Association are essentially the same,but the State required that a new non-profit be set up to receive the permit. The NPDES permit,NCC000001, applies only to Total Nitrogen and gives the group a collective limit for the number of pounds of TN that can be discharged by the members in a year. Each member has an allocation for TN that is expressed in two ways; 1)pounds of Total Nitrogen at the point of discharge and 2) pounds of Total Nitrogen at the estuary(which is the discharge pounds multiplied by the transport factor.) Under the group permit, if the group complies with the collective TN limit, then all of the members are deemed by the State to be compliant with their TN limit. If the NRCA were to violate its TN limit for the year, the group would be subject to enforcement from the State and the bylaws of the Association would reflect that violation back to the member(s)who were in noncompliance with their individual allocation. Under the NRCA Bylaws, the fine paid by the group would ultimately be charged back to the offending members. Page 4 of 16 Accomplishments of the NRCA To date the members of the Neuse River Compliance Association have spent in excess of 50 million dollars on nutrient reduction at their plants. The deadline of a 30% reduction by 2003 was met and exceeded by more than three years. The Total Nitrogen loading from the group in 2000 showed a reduction of 46% over the 1995 levels. By the end of 2001, the group had reduced their nitrogen loading by 53%. As of 2005, the reduction reported by the group was up to 68%! It should be noted that in 2005 the group took on two new members, Unifi-Kinston, LLC and the Marine Corps Air Station at Cherry Point. The collective discharge data for the NRCA is shown in Table 2. A comparison of the discharge from the original group of members and with the addition of the two new members in 2005 is reflected in the table.

The rules for the Neuse Basin do not allow for point sources to trade with non-point sources at this time. No discussion of point source/non-point source trading is contained in this nomination package. Trading among point sources encourages economic efficiency in meeting the overall nitrogen limit in the Neuse,based on the assumption that dischargers will make trades to benefit both parties while still meeting the required reduction. The NRCA has no authority over trades at this time, other than the fact that the bylaws prohibit the selling of nitrogen to a non-member (nitrogen allocation cannot leave the group). However, members are free to buy nitrogen from non-members (nitrogen may be brought in from non-members.) One of the keys to achieving benefits from trading is that there is a"transport factor" for nitrogen assigned to each discharger. The State established Nutrient Management Zones with associated transport factors to the various sub-basins of the Neuse. (See Figure 2.) The concept of the transport factor is not unique to the NC strategy, but works on the premise that nitrogen gradually diminishes as it travels down the Neuse to the estuary. A discharger located further upstream may discharge more nitrogen without having an adverse effect on the estuary. For example,one pound of nitrogen discharged directly into the estuary is assumed to have the same effect as two pounds discharged in the Raleigh area. It would Page 6 of 16 follow that rather than spending a certain amount to reduce its nitrogen in the Raleigh are, that same amount would be better spent to reduce a discharge directly into the Neuse estuary and would achieve twice the benefit. In exchange, a discharger in the Raleigh area who provides funds to reduce a discharge at the estuary would receive the nitrogen allocation that the discharger in the estuary was no longer discharging.

Due to the fact that nitrogen allocation is a scarce commodity in North Carolina and the management strategy did not reserve any allocation for growth in the basin, dischargers are simply not going to sell nitrogen permanently. There have been Page 7 of 16 only two official sales/trades, involving allocation that was purchased from a system that went to land application of the wastewater. The sales have been controversial,have been highlighted by considerable media attention and the State has not allowed the acquired nitrogen to be added to the NRCA permit as of this date. As a complicating factor, the environmental groups that advocate for the Neuse River do not understand the concept of trading and want any and all reductions to be experienced by the river. They put constant pressure on the State to limit trading, even though it is provided for in the rules, and fight to have every pound of nitrogen that is removed from the river to be removed forever. These groups fail to recognize the significant achievements of the NRCA and the extraordinary reductions that have been achieved by these point sources. The 30% reduction that was identified was mandated for non-point sources as well,but there is little or no pressure on the non-point sources to accomplish the required reductions and there is little data to document what reductions have taken place from non-point sources. Due to the limitations that have been discussed previously,the NRCA has had to been extremely innovative in managing nitrogen within the group. The NRCA has specific bylaws and enforcement policies that prevent members from gaining the protection of the group permit if they are not making necessary improvements to their plant and operations. The enforcement policy requires members who exceed their individual allocation to pay an assessment to the group that doubles each year. The monetary basis for the assessment is the amount that the discharger would pay the State of NC to purchase nitrogen from the Ecosystem Enhancement Project. The first year, the member would pay 25%of this amount, 50%the second year, up to the full amount. If the Page 8 of 16 member is reluctant to make necessary improvements to the plant or fails to pay the assessment, the group can vote to remove them from membership,which would subject them to enforcement from the State of NC for violation of their allocation. In this way the group uses peer pressure to encourage continuous improvement among the membership. In the same way,the group provides technical assistance to members who could benefit from improved operational strategies. Due to the diversity of the membership in terms of size and resources, the larger members who have more resources, assist the smaller members who may be lacking in knowledge or funds. The best aspect of the enforcement policy as an incentive for compliance, is that any assessments collected from the members are held in escrow and are returned (in the amount of 80%) to the member once compliance is achieved. The group does retain 20%of these funds as an administrative cost. This seems far more palatable to the dischargers than paying fines to the State without hope of getting any of it back! A good example of the effectiveness of the group compliance approach is the situation that was experienced with a new member to the NRCA in 2005. The Marine Corps Air Station at Cherry Point had been exceeding its nitrogen allocation for some time before joining the NRCA. The base joined the NRCA in order to lease nitrogen for a three to five year period to allow them to comply with their permit while the plant was upgraded. The terms of their membership and their agreement to lease nitrogen, showed a major commitment on the part of Cherry Point to make the improvements needed to meet their allocation. The lease agreement called for the cost of the lease to increase each year, providing an incentive for them to make improvements in a timely manner. With these Page 9 of 16 incentives in place, the Marine base began a comprehensive training program for its operators and made some substantial operational improvements to optimize their treatment process. In the end, Cherry Point never did violate their individual allocation and did not need the allocation they had leased. They continued to pay their lease payments, in good faith and have pursued the necessary improvements to their plant. One important feature of this lease agreement,was that the membership determined that the funds paid by Cherry Point would be earmarked for projects that would directly benefit the Neuse River and nutrient management. The group voted to use the funds to partially fund a reuse project for another member that will essentially divert that member's entire wastewater discharge to a nursery operation during the summer months, thus removing this loading from the river when the stress is the greatest. If Cherry Point were not a member of the NRCA, it is doubtful that any regulatory agency could have compelled it to pay a penalty assessment, and even if a penalty was paid,the funds would not have been used to benefit the Neuse. Two smaller members of the NRCA are still pursuing funding for necessary capital improvements to their plants in order to meet their nitrogen allocations. In the mean time, the group monitors their progress,requires them to make regular reports to the group and provides short term leases opportunities for them to avoid the enforcement assessments that the group's enforcement policy requires. In some respects, the members would rather negotiate a short-term lease for needed nitrogen, rather than to fall subject to "enforcement"by the group. Even though lease costs cannot be recouped by the member Page 10 of 16 (as they can from the enforcement policies), it is often cheaper and better to be considered"in compliance." Accounting Procedures and Evaluation of the Program The NRCA is required to report to the State of NC,Division of Water Quality every six months. The group is required to submit two reports to the State each year that include the total loadings from each member,to determine compliance with the permit, along with other aspects of the group's activities. The Midyear Report is due on Aug. 31 of each year, which includes the last 12 months of Total Nitrogen data for each member, reported as Total Monthly Flow,Monthly Average Total Nitrogen and the loading expressed as pounds for each month and totaled for the period. This report is not used for compliance purposes,but is used to give the State a running 12 month snapshot of the group's loading. The Annual Report is required to be submitted by February 28th of each year and includes all data(as described above) for the calendar year along with a survey of member's activities. This report includes information regarding regionalization, a summary of all purchases, sales,trades, leases or other transactions affecting the allocations of the members, enforcement updates, changes in membership, control strategies for the coming year, a summary of measures taken to control TN for the last year(for each member),and an assessment of progress made and a description of other efforts or projects for the coming year(s). The fact that all of the activities of the association are governed and reported under an NPDES permit make this program fairly unique. This type of reporting and its subsequent review by the State provides transparency for all activities of the NRCA and any leases or trades that might take place. The State discourages temporary leases and encourages permanent trades that then can be Page 11 of 16 reflected in the individual NPDES permits. The State uses the NRCA permit as a means of tracking and accounting for all Total Nitrogen Allocations of the members. The NRCA reports are submitted under the conditions of the NPDES permit and are therefore, public information and subject to public scrutiny as well. A copy of the data portion of the 2005 Annual Report is included in Appendix A. The narrative portion of the report is too lengthy to be included here. The Executive Committee and Executive Director of the NRCA are in contact with the staff of the Division of Water Quality on a continuing basis and meetings are held periodically to discuss issues that affect the permit and the group. The uniqueness of this program necessitates constant communication and the utmost cooperation between the NRCA and the State. We are essentially making this up as we go along, so communication and cooperation are essential to the success of the program and to the development of future strategies to enhance membership in the NRCA and the benefit to the Neuse River. Collaboration and stakeholder involvement have always been a part of the NRCA. By its very nature, it includes representatives from 20 members(large municipalities, small towns, a private utility, industry and a military base.) The diversity of the membership and the various representatives and elected officials who serve as the delegates, deliver a variety of opinions and viewpoints. Due to the state-issued permit, there are opportunities for public input, notice and hearing involving most association activities. The association has kept the conservation groups informed of their efforts and has supplied them with copies of the annual reports. The group is actively involved with two different universities in the North Carolina University System to participate in research Page 12 of 16 and the sharing of data on the Neuse Estuary and to draw on the expertise of academia. These research efforts are explained in a subsequent section of the nomination. Actual or Anticipated Environmental Improvement To reiterate the actual environmental improvement that has been experienced by the Neuse River, thanks to the NRCA: in 1995 the point sources who make up the current membership of the NRCA discharged 1,784,130 pounds to the Neuse River Estuary. The permit that was in force in 2003 and 2004,permitted the group to discharge 1,073,115 pounds of Total Nitrogen. The group reported a discharge of just 722,374 pounds or 67% of the permitted load. In 2004, the members decreased this amount by 163,821 pounds, discharging 558,553 pounds of nitrogen(52%of the permitted limit.) In 2005 the group discharged 566,627 pounds of TN, or 50%of its permitted limit(which increased to 1, 137,171 due to the addition of two new members and their allocations.) The total impact on the Neuse was the reduction of the Total Nitrogen load by 68%or a total of 1,217,503 pounds in 2005 over what was discharged in 1995. If you look at the cumulative reduction since 1996, the NRCA has kept 7,337,508 pounds of TN out of the Neuse River from what was being discharged during the baseline year of 1995. One can only imagine the benefits to the river and estuary from a reduction of this magnitude. Actual or Expected Economic Benefits The economic benefits that have been realized by the Neuse River and its estuary and the State of North Carolina thanks to the efforts of the NRCA are difficult to quantify. A great deal of money has been spent by the municipalities and industries that hold membership in the NRCA. It is estimated that over fifty million dollars has been spent Page 13 of 16 on upgrades to wastewater facilities and to construct new facilities to remove nitrogen from the receiving waters. The conditions in the Neuse River and the estuary have greatly improved, and the NRCA is now participating in research being conducted by the University of North Carolina at Chapel Hill, Institute of Marine Science to further document the recovery of the estuarine system. The NRCA is supporting this research, in the amount of$65,000 per year,to assist in this effort. In addition to the economic benefits that have undoubtedly been experienced by the aesthetic improvements and public perception of the river and the coast, the other major economic benefit is the growth that the NRCA has now provided for in the eastern part of North Carolina. The development of the TMDL for the Neuse, mandated a 30%reduction in nitrogen loading from point sources. As mentioned previously,there were no provisions for growth in terms of new or expanding wastewater facilities. The 68%reduction that has been realized by the NRCA has bought the State of North Carolina some room to grow, in a part of North Carolina that is trying to grow very rapidly. The improvements made by NRCA members and the fact that many of our members are treating well below what is accepted as Best Available Technology,have provided an excess allocation that stands to allow some growth in the basin that otherwise would have been impossible. The NRCA is currently participating in negotiations with the State that might allow the members of the NRCA to leverage some additional flows for their facilities,based on their ability to treat below BAT levels and based on the unused portion of the allocation that they group holds. The group shares information and promotes reuse projects that will also remove flow and nitrogen from the wastewater Page 14 of 16 discharges, that could allow for more growth for the towns and cities of eastern North Carolina. The NRCA is anxious to pursue point source, non-point source trading as a way of providing additional reductions from agriculture and non-point sources that could help their town provide more growth, while protecting the river and the estuary. The group is currently supporting research by North Carolina State University into alternative methods of providing nutrient offsets, that might allow municipalities to expand buffers within the basin,purchase conservation easements and construct stormwater retrofit projects that would benefit the river and the estuary. The group hopes that by conducting this research and showing the benefit and cost of other alternatives, that the Environmental Management Commission of NC could be persuaded to add some additional measures to provide for this type of non-point source,point source trading. Conclusion This group has had to been innovative, cooperative and altruistic in their struggle to reduce nitrogen loadings to protect the Neuse, while meeting the pressures of growth and economic development. The have proven their ability to meet the challenge of a mandated reduction in nitrogen loading, by working together and sharing information and resources and accomplishing what no one though was possible. They take their obligation to the Neuse very seriously and conduct additional research and monitoring to look for new ways to improve the estuary and to optimize nitrogen removal at their plants. Their efforts have gone unnoticed and unappreciated by the citizens of North Carolina, thanks to conservation groups that fail to acknowledge the effort and commitment they have demonstrated. The NRCA has not simply used nutrient trading in Page 15 of 16 its most traditional sense,but has looked for innovative ways to bring new tools to the trading tool box. To be a member of the NRCA is a much bigger commitment than just agreeing to buy some nitrogen when you need it. This group constantly strives to bring all its members up to a standard of excellence that provides the best treatment and the cleanest reclaimed water to protect the Neuse River and its estuary.
