Permit Number NCS000076 New Hanover County Dear Permittee: Your facility is currently covered for stormwater discharge under NPDES Permit NCS000076. This permit expires on November 30. 1999. In order to assure your continued coverage under your permit. you must apply to the Division of Water Quality (DWQ) for renewal of your permit. To make this renewal process easier, we are informing you in advance that your permit will be expiring. Enclosed you will find an individual permit renewal application form, supplemental information request, and Stormwater Pollution Prevention Plan certification. Filing the application form along with the requested supplimental information will constitute your application for renewal of your permit. The application form must be completed and returned along with all requested information by June 14, 1999 in order to constitute a timely renewal filing. Recent legislation modified the fee structure for DWQ permits. Renewal fees have been eliminated and annual fees have been changed. The new annual fee for your permit is now $715.00 (you will be invoiced later this year for your annual fee_) A copy of the new fee schedule is enclosed in this package. Failure to request renewal by June 14, 1999 may result in a civil assessment of at least $250.00. Larger penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could result in assessments of civil penalties of up to $ 10.000 per day.

Phone No 910/395-7262 Address: 310 North College Road, Wilmington, NC 2W5 I. Monthly, or after every runoff -producing rainfall event, whichever comes first: A. Inspect the trash rack; remove accumulated debris, repair/replace if it is not functioning. B. Inspect and clear the orifice of any obstructions. If a pump is used as the drawdown mechanism, pump operation will be checked. A log of test runs of the pump will be kept on site and made available to DWQ personnel upon request. C. Inspect the pond side slopes and inlet swales; remove trash, and repair eroded areas before the next rainfall event. D. If the pond is operated with a vegetated filter, the filter will be checked for sediment accumulation, trash accumulation, erosion and proper operation of the flow spreader mechanism. Repairs/cleaning will be done as necessary. H. Quarterly (Four times a year): A. Inspect the collection system (i.e., catch basins, piping, swales) for proper functioning. Accumulated trash will be cleared from basin grates, basin bottoms, and piping will be checked for obstructions and cleared as required. B. Pond inlet pipes will be checked for undercutting. Riprap or other energy dissipation structures will be replaced, and broken pipes will be repaired. III. Semi-annually (twice a year): A. Accumulated sediment from the bottom of the outlet structure will be removed. B. The forebay depth will be checked at various points. Sediment removal is required when the depth is reduced to 75 % of original design depth of 4 feet- C. Swales, including the vegetated filter if applicable, will be regraveled as necessary. Repair eroded areas immediately. 0 POND MAINTENANCE REQUIREMENTS PAGE 2 IV. Annually (Once a year): A. The pond depth will be checked at various points. Sediment removal is required when the depth is reduced to 75 % of the original design depth or 3' , whichever is greater. Design depth is 7-1/2 feet, measured vertically from the orifice down to the pond's bottom. Sediment must be removed to at least the original design depth. V . General: A. Maintenance of the side slopes is required. Maximum grass height will be 6". B. Cattails are encouraged along the pond perimeter; however, they will be removed when they cover more than 1/2 the surface area of the pond. The best time to cut them is at the end of the growing season, in November. Environmentally sensitive chemicals for use in killing cattails can also be used. Contact your nearest Agricultural Extension Agent. C. The orifice/pump is designed to draw down the pond in 2-5 days. If drawdown is not accomplished in that time, the orifice will be replaced with a larger or smaller orifice. Slow drawdown may be attributed to a clogged system. The source of the clogging will be found and eliminated. D. All components of the detention pond system will be kept in good working order. Repair or replacement components will meet the original design specifications as per the approved stormwater plan. If previously approved components are determined to be ineffective, the component will be redesigned and/or replaced. V. Special Requirements: I, William M. Cash, Wilmington Plant Project Coordinator, hereby acknowledge that I am the financially (please print or type name clearly) responsible parry for maintenance of this detention pond. I will be responsible for the performance of the maintenance as outlined above, as part of the Stormwater Management Permit received for this project.

Attachment B contains a table listing the total drainage area acreage for the outfolls discussed in the next sections. NPDES Permitted Outfalls Outfalls 001 & 002 NPDES Permit No. NCO003794 covers wastewater discharges from the facility via NPDES Outfalls 001 and 002 (see attachment F Drawing labeled 'Overall Sheet"). These two outfolls also discharge stormwater runoff from portions of the facility where chemical storage, loading and unloading occur. Outfall 001 also receives stormwater runoff from ❑ portion of the parking area labeled Drainage Area 14. This drainage area is considered to be an exempt area since it is only a parking lot (see Attachment F, Drawing Sheet labeled "Quad 3"). Outfall 001 has a total drainage area of 2.24 acres. This total does not include the exempt Drainage Area 74. Outfall 002 has a total . drainage area of 9.24 acres with 6.87 acres being impervious. Outfails 003,004 & 005 The NPDES outfalls at the Coming Wilmington facility discharging only stormwater receive runoff from 12.46 acres, 7.28 acres being impervious, and discharges through three (3) separate outfalls identified as Ouffall 003, Ouffoll 004 and Outfall 005 (see Attachment F, Drawing labeled "Overall Sheet). Drainage Area 3 is bounded on the south by the property line (see Attachment F, Drawing Sheets labeled 'Quad 1 ' and "Quad 4). The total drainage area is 7.87 acres with 5.15 acres being impervious. Drainage Area 3 discharges through Outfall 003. A stormwater retention pond was constructed in Drainage Area 3 in 7998 as required by the terms and condition of 15A NCAC 2H .1000 (see Attachment E, 'State Stormwater Management Systems Permit No. SW8 980441 ). Drainage Area 4 receives stormwater drainage from a portion of the Manufacturing Building roof (see Attachment F Drawing Sheet labeled "Quad 4). All2.12 acres of Area 4 are impervious. Drainage Area 4 discharges through Outfall 004. Also, exempt Drainage Area 5D discharges through Outf611004. Drainage Area 5D is O.64 acres of impervious surface. Drainage Areas 5A and 5B discharge to a stormwater retention pond (see Attachment C, 'State Stormwoter Management Systems Permit No. SW8 950318) located prior to Outfall 005. The retention pond was constructed in 7996. Drainage Area 5A contains 2.54 . total acres including 0.61 impervious acres. Drainage Area 5B is 7.07 acres with 5.70 acres impervious. Two exempt drainage areas discharge through Outfall 005. Exempt • Drainage Area 5C is comprised of a manicured front lawn, with 2.21 total acres and 0.33 acres impervious. Exempt Drainage Area 5D receives stormwater drainage from an administrative office building roof (see Attachment F, Drawing Sheets labeled "Quad 3" and "Quad 4 "). Outfails Exempt From NPDES Permitting Eight outfalls are identified on the storm drain piping drawings in Attachment F as "Exempt Outfolls (EO) These ore outfalls receive water from areas containing no industrial activity and no potential for stormwater contamination; therefore these outfalls and corresponding drainage area are exempt under NPDES regulations. Drainage Areas Not Being Discharged Through Ouffalls The remainder of the Corning Incorporated property, Drainage Area 6 and Drainage Area 9, is completely pervious with no direct discharge points from the site. Drainage Area 6 is 2.54 acres and Drainage Area 9 is 10.22 acres. Site Drainage Controls The Wilmington plant system design standard requires storm drain systems to function during a 50-year storm event. All three (3) stormwater retention ponds meet the requirements of NCDWQ State Stormwater Management Systems permit program. AI123 secondary containment systems located at the facility have been upgraded to . retain the capacity of the largest vessel plus a 24-hour/25-year storm event (defined as 8 inches of rainfall for the Wilmington area). The Stormwater Pollution Prevention Plan (SP3) Secondary Containment Vessels Compliance Program includes keyed lockouts of the drain systems. The Area SP3 team identified 'appropriate testing" and record keeping provisions during Best Management Practices (BMP) development. Collected stormwater from all 23 secondary containment systems is evaluated prior to making a determination to discharge any collected stormwater to the outfalls. There is an alternate system available for the discharge of contaminated stormwater. Collected stormwater can be redirected, if required due to contamination, to the Pollution Abatement Process for pretreatment prior to discharge to the City of Wilmington WWTP. 0 • #3 SUMMARY - Visual Monitoring results of Outfalls 001, 002, 003, 004 Outfall DSNO01 • • Dates monitored: Parameters surveyed: Observations: 6/13/96 Visual monitoring per #I.A.2.g(3)" No issues 11/14/96 Visual monitoring per #I.A.2.g(3)" No issues 5128/97 Visual monitoring per #I.A.2.g(3)' No issues 10/28/97 Visual monitoring per #1.A.2.g(3)' No issues 6/10/98 Visual monitoring per #I.A.2.g(3)' No issues 11/18/98 Visual monitoring per #I.A.2.g(3)' No issues Outfall DSNO02 Dates monitored: Parameters surveyed: Observations: 6/13/96 Visual monitoring per #I.A.2.g(3)' No issues 11 /14/96 Visual monitoring per #I.A.2.g(3)' No issues 5/28/97 Visual monitoring per #I.A.2.g(3)' No issues 10/28/97 Visual monitoring per #I.A.2.g(3)" No issues 6/10/98 Visual monitoring per #I.A.2.g(3)' No issues 11/18/98 Visual monitoring per #I.A.2.g(3)' No issues Outfall DSNO03 Dates monitored: Parameters surveyed: Observations: 6/13/96 Visual monitoring per #I.A.2.g(3)' No issues 11 /14/96 Visual monitoring per #I.A.2.g(3)' No issues 5/2B/97 Visual monitoring per #I.A.2.g(3)` No issues 10/28/97 Visual monitoring per #I.A.2.g(3)` No issues 6/10/98 Visual monitoring per #I.A.2.g(3)* No issues 11/18/98 Visual monitoring per #I.A.2.g(3)" No issues Outfall DSNO04 Dates monitored: Parameters surveyed: Observations: 6/13/96 Visual monitoring per #I.A.2.g(3)' No issues 11/14/96 Visual monitoring per #I.A.2.g(3)' No issues 5/28/97 Visual monitoring per #I.A.2.g(3)' No issues 10/28/97 Visual monitoring per #I.A.2.g(3)" No issues 6/10/98 Visual monitoring per #I.A.2.g(3)* No issues 11/18/98 Visual monitoring per #I.A.2.g(3)` No issues I.A.2.g (3) of the permit requires observation of color, odor, clarity, floating solids, suspended solids, foam, oil sheen and other obvious indicators of stormwater pollution 0 #3 SUMMARY - Visual Monitoring results of Retention Ponds Front Retention Pond Dates monitored: Parameters surveyed: Observations: 6/13/96 Visual monitoring per #I.A.2.g(3)' No issues 11/14/96 Visual monitoring per #I.A,2.g(3)' No issues 5/28/97 Visual monitoring per #I.A.2.g(3)" No issues 10/28/97 Visual monitoring per #I.A.2.g(3)` No issues 6/10/98 Visual monitoring per #I.A.2.g(3)' No issues 11/18/98 Visual monitoring per #I.A.2.g(3)* No issues Back Retention Pond Dates monitored: Parameters surveyed: Observations: 11 /14/96 Visual monitoring per #I.A.2.g(3)' No issues 5/28/97 Visual monitoring per #I.A.2.g(3)' No issues 10/28/97 Visual monitoring per #I.A.2.g(3)" No issues 6/10/98 Visual monitoring per #I.A.2.g(3)" No issues 11/18/98 Visual monitoring per #I.A.2.g(3)' No issues .
