Program Summary and Assessment North Carolina State University (University, NC State) currently holds a Permit to Discharge Stormwater under the National Pollutant Discharge Elimination System (NPDES). Permit Number NCS000376 was issued on April 18, 2005 with an effective date of May 1, 2005. This report is intended to meet the permit condition found at Part II, Section A, Item 1. The report summarizes the University's activities under the permit for the previous 12-month period. Program Summary The Program lost the full-time position of Stormwater Program Manager in August 2008. The role of Stormwater Program Manager was absorbed by the Environmental Affairs Manager and a support staff person. The Program was evaluated as part of a detailed multi -media compliance audit, ' conducted during the summer of 2008. The audit identified several program deficiencies which have been the subject of considerable attention during the year, just ending. The Stormwater Program was reorganized, and now operates under a streamlined Stormwater Committee.

Component Discussions A. Education and Outreach Program North Carolina State University believes that an integral part of stormwater management involves the education of the campus community about our local water resources, how we affect water quality, and what we can do to minimize pollution and damage and lessen our impact on the environment. In this context, the University has developed an Education and Outreach Program that provides information to those staff persons and contractors which have a direct impact on stormwater quality. Awareness Training & Educational Workshops NC State Stormwater Management training specifically targets University Project ' Managers from Design and Construction Services, as well as members of the development community such as engineers, architects, contractors, surveyors, and planners who propose to work on the campuses of NC State. Training is designed to ' educate those involved with the design, construction and maintenance of University projects. Table 3 outlines the type of training available on an annual basis. r��t ," :Trab`Ie�2�;�Yr"airn:n nii±_d.ucatioina ar: ho '' Fro ,' a, Urtirrer}si Pro'e t�Mana ers W �k &. �.

Along with the display, many brochures, pamphlets, and other handouts discussing pollution prevention and water quality issues are available. 1 North Carolina State University Permit No. NCS000376 ' August 2009 Annual Report B. Public Involvement The requirement in the University's Stormwater Permit addressing public involvement reflects the origins of the municipal stormwater regulatory framework. This is a standard requirement for federally -mandated environmental regulatory programs designed for implementation at the city government level. However, application of the stormwater permit to the University has been, and will continue to be, more driven by facility management principles, than by the processes applied to municipal governance. The Program is based upon agreed -Upon plans and procedures, which are implemented by affected University component organizations. ■ In the context of the campus environment, the students are considered the public. Our student body is an important member of the University community, its involvement in ' the workings of the Stormwater Pr, gram is valued and encouraged, North Carolina State University Permit No. NCS000376 August 2009 Annual Report 4 C. Illicit Discharge Detection and Elimination Program The University continues to implement an Illicit Discharge Detection and Elimination Program. The program provides a standardized way to identify report, resolve and document illicit discharges. The table provided below summarizes actions under this program for the subject reporting period.

Stormwater System Inventory and Mapping Databases and maps describing the stormwater system, including collection devices, conveyances, structural controls, and outfalls, are being validated and consolidated into a single stormwater system inventory. The stormwater system inventory will be managed through the University's Architectural, Engineering, and Real Estate (AERES) System. AERES provides real-time access to facility building, room space, and infrastructure information for the University (Raleigh Campus). Access to AERES is restricted to University employees. AERES 2.1 with GIS is scheduled to go to production in September. Stormwater data is being prepared in parallel with AERES system development. ' Approximately 80% of structural BMP devices have been identified and mapped in GIS. The remaining 20% have been identified, but have not been mapped. We are currently compiling, converting, and verifying survey data for the underground piping network, which will then be assigned unique identification numbers and tracked in the system. Previously identified outfall locations will to be mapped next. Impervious surface data for the campus, current as of 2007, has been obtained from Wake County GIS. Other current, publicly available GIS data has been gathered and entered into the system, including surface water features and topography. The University is researching the availability of current watershed GIS data. North Carolina State University Permit No. NCS000376 August 2009 Annual Report 0 E. Sediment and Erosion Control Program NC State Stormwater Management has been implementing a Sediment and Erosion Control Program since 2004. The program is composed of two procedures: Sediment and Erosion Control Guidelines and Technical Specifications Sediment and Erosion Control Evaluation Procedure As stated in the Permit, the NC DENR Division of Land Resources, Land Quality Section provides Plan review and approval, and also periodic inspections. However, also under the Permit, the University performs monthly inspections of all active construction sites and provides the results of those inspections to Land Quality. North Carolina State University 7 Permit No. NCS000376 August 2009 Annual Report I F. Post -Construction Stormwater Management Program 9 9 ' The post -construction stormwater controls necessary to meet Program requirements actually begins well in advance of project construction. Any project which is subject to the Program must provide a stormwater plan for review and approval prior to initiating construction. NC State Stormwater Management has developed and implemented a Pre- and Post - Construction Stormwater Management Program in accordance with the Neuse River Basin Nutrient Sensitive Waters Management Strategy: Basinwide Stormwater ' Requirements (15A NCAC 2B .0235). All projects are required to develop a plan based on the Stormwater Management Plan Guidelines. Currently, the University is conducting a survey of all permanent BMPs (as part of the ' system inventory and mapping activities). The survey will be used to identify and prioritize maintenance requirements. All permanent structural BMPs are inspected and maintained in accordance with the University's BMP Inspection and Maintenance Program. ' North Carolina State University 8 Permit No. NCS000376 August 2009 Annual Report G. Pollution Prevention and Good Housekeeping NC State Stormwater Management and various affected departments will continue to implement the non-structural best management practices, preventative measures and innovative programs currently in place. A facility -wide stormwater exposure assessment has been completed, which is being used as input to develop necessary pollution prevention plans. The Stormwater Program is working with the following organizations on pollution prevention plan development. Dining Grounds Maintenance Transportation Athletics Housing Various Academic Departments Pollution prevention efforts will be extended to other campus organizations, based upon the results of the exposure assessment. North Carolina State University Permit No. NCS000376 August 2009 Annual Report I H. Structural Stormwater Controls Inspection and Maintenance ' All structural stormwater controls at the Raleigh Campus are subject to the NC State Stormwater Structural Controls Inspection and Maintenance Procedure. The procedure ' implements the NCDENR DWQ 2007 BMP Manual. Also, all inspection and maintenance activities are performed by University staff that holds an active BMP Inspection and Maintenance Certification. North Carolina State University Permit No. NCS000376 August 2009 Annual Report t 10 I. Retrofits North Carolina State University was granted authority by NC DENR to collect internal offset payments and utilize the money for retrofit BMPs that would improve nitrogen reduction elsewhere on campus. Offset payment fees are collected from projects that do not exceed the export limits for new development projects that exceed the 3.6 Ibs/acre /yr requirement. NC State Stormwater Management has contributed funds to various retrofit projects around campus. The table below summarizes the most recent contributions.

Research and Program Assessment The Stormwater Program did not perform any research during the subject period. The Program was subject to a comprehensive independent compliance audit, which was part of a large (multi -media) University -wide audit. North Carolina State University Permit No. NCS000376 August 2009 Annual Report 12 K. Land Use Planning At the University, land use planning is conducted under the term, "Master Planning," which is typical for a University setting. The master planning process integrates a number of planning variables, including stormwater management. The University Master Plan was last updated in 2007. The Master Plan is a living document, subject to continual review and revision as new projects are being designed and constructed. North Carolina State University 13 Permit No. NCS000376 August 2009 Annual Report I L. Monitoring NC State Stormwater Management has contracted with Piedmont Geologic to conduct stormwater discharge and water quality monitoring. The stormwater sampling plan was ' implemented twice during the subject period; during August 2008 and February 2009. Results of those sampling actions are summarized in Table 1. ' North Carolina State University Permit No. NCS000376 August 2009 Annual Report 14 III. Proposed Program Changes and Schedule The current permit expires on April 1, 2010. In compliance with the permit, the University will submit a permit renewal application before October 31, 2009. The permit renewal application will be based upon the requirements for a Phase II community [GS 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 19, 1994 (or as subsequently amended)]. The University will access DWQ Stormwater Section guidance in the development of this permit renewal application.
