Permit Number— NCG140350 County • Wake Dear Mr. Holding: Natural Resources John E. Skvarla, III Secretary On June 19, 2013, Autumn Romanski, of the Division of Water Quality (DWQ), Raleigh Regional Office, performed a stormwater compliance evaluation inspection of the Thomas Concrete Plant in Wake Forest. Mr. Brian Westfall, the Plant Manager on the site had a thorough knowledge of the permit and his implementation of Stormwater Best Management Practices was evident. The facility was in compliance with the permit the day of the inspection. Thank you for your staffs time, assistance and cooperation. Inspection findings are listed below.

Stormwater runoff and process wastewater generated at such facilities is regulated by General Permit NCG140000. DWQ has therefore issued Thomas Concrete certificate of coverage, NCG140350, which became effective on July 1, 2011 and expires on June 30, 2016. The facility has plugged the stormwater collection trough, such that stormwater no longer direct discharges from the trough. The facility has also re-routed stormwater from a prior stormwater outfall to the collection trough, thus eliminating a stormwater outlet. The facility is deemed permitted to re -use the stormwater and has instituted re -use of the stormwater from the trough, such that discharge would be only be in the event that the volume of water stored in the trough exceeded the capacity of the trough. The plant monitors the trough for pump out, maintenance, and cleaning as needed.

The site contains a trough (retention basin) that stores the stormwater. The stormwater basin is pumped out and water is re -used on -site. The sample was obtained by sampling the stormwater in the trough, since no stormwater was discharging to the BMP Dry retention basin from the trough. This likely led to elevated values TSS. (You may expect poorer settling performance of the stormwater in the trough in a rain event). If there is no discharge from the trough, please do not sample, as sampling is intended to capture the stormwater discharge as it leaves the permittee's property. PLEASE record no flow, if there is no discharge. IF the trough discharges at any time during the permit monitoring periods, then please sample the discharge as it leaves the plant's property.

The outfall has been re -constructed as a retention basin and the water is pumped out of the basin and reused at the site. The site no longer discharges direct off the property, but the stormwater retention basin could overflow and (sheetflow) off the property if stormwater exceeds retention basin capacity.

Georgoulias Thomas Concrete —Wake Forest Plant rev. 2/ 14/05 Summary This facility submitted a Notice of Intent to be covered under General Permit NCG140000 (Ready Mix Concrete). This facility is a concrete ready mix plant. The stormwater/wastewater discharge drains to an unnamed tributary (UT) to the Neuse River, a Class WS-IV NSW stream in the Neuse River Basin. This facility is located in Wake County, handled by the Raleigh Regional Office. Application review a) The permit application has been signed and sufficiently completed. No; consultant signed the application. b) The SIC code accurately describes this facility's activities and is covered by this general permit. Yes. SIC: 3273 (Ready -mix Concrete) c) Does this facility have other permits? No. d) Hazardous Waste Activities? No. e) Stormwater BMPs and Wastewater discharge: This facility has a recycle pond and settling basin (with multiple cells). Details regarding volume, retention time, and surface area of stormwater treatment facilities were not available for the application (see page 5 of the NOI); performance of current treatment facilities and any proposed modifications will be evaluated during development of the Storm Water Pollution Prevention Plan. Process wastewater from vehicle and equipment cleaning, and raw stockpile material wetting is routed to the settling pond. Mixing drum washout water is purged directly into the first settling pond cell. The application indicated "purge material and water from the mix plant" is transported via truck to the fast settling pond cell (covered in NCG14?). Per contact (Consultant Bill Rice, F&R), about twice a day, mix plant material (roughly 2.5-3 cu. ft. of material in 500 gal. water) is dropped into first settling basin, which subsequently drains to the recycle pond —essentially very similar to mix drum clean -out water. Whether it can be called mix drum washout or not, it should be covered under "process wastewater associated with Recycle Systems" in the NCG14 Permit. Facility recycles most water at the site via the recycle pond system. f) Regional Office input requested: 1/25/2005, 2/14/2005 (DEH & DWQ) RO Approval received: Phone Logs: 1/25/05: Spoke to Myrl Nisely at the Raleigh Regional Office re: issue of purge material and water from the mix plant going into the pond.

The only raw material stockpile that requires wetting is the light -weight aggregate stockpile (shown on the attached figure). Run off from this pile runs onto the lot and into the perimeter curb drainage channels, ultimately ending into the aforementioned on -site settling basin for catching fines from surface flows off of the plant lot . • Mixing Drum Cleaning. Truck mix drums are washed out and purged directly into the first settling pond cell where their suspended solids settle out as waters slowly travel into the successive pond cells via gravity flow. The mix plant drum is purged up to twice a day, depending on business volume. Purged material and water from the mix plant is dropped into a truck and driven to the first settling pond cell. • Design Volume, Retention Time, Surface Area, Etc. Currently, the subject facility is in the process of being studied for purposes of developing a Storm Water Pollution Prevention Plan (SP3). At this current time, no data exists that would sufficiently respond to the questions regarding volume, retention time, and surface area of the existing stormwater treatment facilities. Performance of the existing and any proposed BMPs will be discussed with the DWo and Thomas Concrete during the development of the forthcoming SP3.

The compliance refers to requiring a Stormwater Pollution Prevention Plan which is not a requirement of this permit. The corrected compliance language that should go under Part III, Section A: 1. is shown below. We have also attached a new page reflecting this change for your permit file (Part III page 1 of 11). This new page should replace the current page in your permit. SECTION A: COMPLIANCE AND LIABILITY 1. Compliance Schedule The permittee shall comply with the permit in accordance with the following schedule: Existing Facilities: Upon the effective date of the Certificate of Coverage the permittee shall comply with all of the conditions detailed in Part 11, Section A: Final Limitations and Controls for Stormwater Discharges. New Facilities: Upon the beginning of discharges from the operation of the industrial activity the permittee shall comply with all conditions detailed in Part 11, Section A: Final Limitations and Controls for Stormwater Discharges.

These two facilities - the North Wake Municipal Solid Waste Facility located on Durant Road in north Raleigh and Feltonsville Landfill located on Old Smithfield Road in Holly Springs - have been provided coverage by your office through Stormwater General Permit Number 120000, which was renewed for a five year period on August 23, 2002. These two facilities are identified as COC Numbers 120020 and 120021 on the renewal letters of that date. In April 2003, Wake County was notified that these two facilities had been granted new NPDES General Permits under General PernutNCG080000. Ina letter dated June 9, 2003, CDM informed the Division of Water Quality (DWQ) that the new Stormwater General Permits issued on April 25, 2003 should not have been issued for these two facilities since active Stormwater General Permits were in place. The DWQ informed CDM, in a letter dated June 23, 2003 (attached), that the NPDES General Permits NCG080672 and NCG080673 were rescinded. The letter implied that this rescission was based on the assumption that activities at the sites, covered under the general permits, had ceased or been eliminated. The intent of this letter is to inform the DWQ that these two facilities are currently active and complying with the requirements outlined in the previously renewed Stormwater General Permits COC Numbers 120020 and 120021 issued in August 2002. Please let us know if this is in conflict with the DWQ's understanding of the situation. consulting • engineering - construction - operations Mrs. Vanessa Manuel August 8, 2003 Page 2 Thank you in advance for your review of this information.

Easley, Governor William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality A review of applications for coverage under NCG120000 for stormwater discharges from the Hwy 55 C & D Landfill, on Old Smithfield Road, Apex, Wake County, which was received in this office last summer has been completed. After review of this matter we have determined that an NPDES stormwater permit is not required for the landfill. The only landfills that are categorically subject to NPDES stormwater permits are those landfills that receive waste material from Industrial Activities (mostly manufacturing firms). LCID landfills do not meet this description and are thus not subject to the requirement to categorically have a permit. Therefore, your NOI and fee check for $80 are being returned to you without further action. It will not be necessary to have a stormwater NPDES permit for this facility at this time.

General Stormwater — r Permit NCG120000 I Technical Bulletin for NCG120000. Landfills Last Revised 10/25/2012 What is regulated by this General Permit? This General Permit regulates stormwater discharges from landfills (including construction and demolition landfills) and associated on -site activities. What does my DWQ stormwater permit require me to do? ✓implement your approved Sedimentation and Erosion Control Plan (Part 11, Section A). ✓Implement your solid waste permit from the Division of Waste Management (Part 11, Section A). ✓Install secondary containment for bulk storage of liquids, including petroleum products (Part 11, Section A). ✓Conduct semi-annual testing of the stormwater discharges, and report results to DWQ (Part ll Sections 8 and Q. -'Conduct semi-annual visual monitoring of stormwater discharge flows for the characteristics listed in the permit, and keep the records of the visual monitoring on your site (Part ll, Section D). ✓Inspect your sediment and erosion control measures and your stormwater control measures weekly, and after every 1/2" rain. Keep the records of the inspections on your site (Part Il, Section D). ✓Respond to monitoring results that exceed the numerical benchmarks with management actions to reduce the level of pollutants in the stormwater discharges. Note that the numerical benchmarks should be considered as 'action levels, rather than permit limits, and so would not alone generate permit violations. (Part Il, Sections 8, C, and D). ✓The General Permit seeks to reduce pollution in rainfall runoff from landfills by requiring site managers to be aware of, and to reduce, contamination in stormwater runoff. ✓Federal and state laws and water regulations require the reduction of pollution in stormwater from landfills. ✓Those laws and regulations reflect the public's support for clean natural waters in our state and nation. • Although they were previously subject to water quality regulation according to federal rule, the General Permit now specifically clarifies that construction and demolition landfills may be regulated by this permit. • The permittee may now sample discharges from any meosureable storm event, rather than from a representative event. This change should make it easier to obtain a sample from a qualifying rain event. • The permit text now clarifies that failure to sample due to adverse weather, or due to no discharge during the nor- mal monitoring period, may be excused. However, the permit now provides that additional monthly monitoring for unexcused failures to monitor may be required by DWQ. • The permit now provides that sampling is not required outside of the facility's normal operating hours. • Visual monitoring of the discharge flows for the characteristics listed in the permit has been reduced in frequency from weekly to semi-annual. However, inspections of the sedimentation and erosion control measures have been retained as a weekly obligation. • The permit text now clarifies that if DWQ relieves the permittee from monthly monitoring under Tier 2, that relief would continue into subsequent permit renewals, unless DWQ's relief letter provides otherwise. • Vehicle Maintenance Areas (VMA) will be monitored for Total Petroleum Hydrocarbons (TPH) rather than Oil & Grease (0&G). • VMA monitoring is now triggered by the total oil usage for motor oil plus hydraulic oil. The trigger remains at a total of 55 gallons per month, average. • A lower TSS benchmark of 50 mg/L applies for discharges to especially protected water classifications. PAGE TECHNICAL BULLETIN FOR N.C. GENERAL STORMWATER PERMIT NCG120000 LAST REV. 10/25/2012 1 Frequently Asked Questions Do 1 have to monitor all outfalls? Yes. However, you may request ROS (Representative Outfall Status). If ROS is approved, this status allows analytical monitoring at fewer outfalls. To request ROS, submit a ROS Request Form SWU- ROS (from our website) to the DWQ Regional Office. What if I can't collect a storm - water discharge in 30 minutes? When distances separate multiple out - falls and preclude collection within 30 minutes of each discharge event, begin collection within 30 minutes and then continue until all outfalls are sampled. Documentation of the site circum- stances must be kept with the sampling records on site. Can I take more samples than is required by my permit? Yes. The permittee may take multiple samples at any time while under per- mit coverage. The permittee may find the extra sampling useful to quickly identify causes of benchmark ex- ceedances. All samplipg for the permit parameters must be reported to DWQ on the DMR forms. What if I can't sample because of bad weather? Adverse weather is dangerous or it may limit access for sampling person- nel. Your documentation of adverse weather and the reasons for not Sam- pling must be included in your on -site records. A substitute sample may be taken during the next qualifying storm event. What if I don't address visual monitoring problems? If you do not respond to problems seen in visual monitoring, DWQ may require that you increase the visual monitoring frequency, apply for an individual per- mit, implement in -stream monitoring, install or modify structural stormwater controls, or implement other controls. What if I forget to monitor? DWQ may require monthly monitoring for a specified time period. Why did you replace Oil & Grease with TPH in VM areas? The TPH test only targets chemicals de- rived from crude oil. The Oil & Grease (0&G) test recovers fats from animal & vegetable sources and chemicals from crude oil. Because TPH is more specific, it is a better parameter for vehicle main- tenance areas. The TPH method we are specifying is EPA 1664A (SGT-HEM). It is important to note that DWQ is not speci- fying the more expensive Gas Chromoto- graph (GC) TPH method. DWQ found lab costs for EPA 1664A (SGT-HEM) to be comparable to O&G test costs. To test these parameters in stormwater, labs must perform this test in accordance with EPA procedures, but do not need to be certified. Note: A lower benchmark applies for TPH: 15 mg/I (not 30 mg/1). Why are there two benchmark values for TSS? The 100 mg/L benchmark applies to most rivers, lakes, and creeks in North Carolina. However, some other waters must receive special protection under North Carolina water quality rules, and in this permit discharges to them are subject to the more protective bench- mark of 50 mg/L. Those waters classified as Trout Waters, High Quality Waters, Outstanding Resource Waters, and Pri- mary Nursery Areas receive this extra protection. Where and when do I send the monitoring reports? See your permit text, Part I11, Section E. Who can help me? Division of Water Quality (DWQ) Offices: Asheville Office ............. (828)296-4500 Fayetteville Office ........ .. (910) 433-3300 Mooresville Office......... (704) 663-1699 Raleigh Olfcg}...,,........ (919) 791y4200 Must I use a North Carolina certified laboratory? No. North Carolina water quality rules do not require that analyses of storm - water be accomplished by a certified facility. Please note however, federal rules at 40CFR136 do require that test- ing for this permit be by EPA -approved lab methods. Analysis by a North Caro- lina certified lab is often the easiest way to insure compliance with federal rules. Note that pH is a special case, and must be measured within 15 minutes of the sample recovery. You must ei- ther train on -site staff to conduct pH testing, or contract with commercial services to test pH in accordance with EPA field testing methods. Who inspects me, and for what? Staff from the DWQ Regional Offices shown below will inspect your facility. They will typically ask to see your Sedi- mentation and Erosion Control Plan to see that it is being fully implemented. They will typically ask to see your re- cent monitoring results. They will typi- cally tour the facility with a focus on the stormwater discharge outfalls and on your general housekeeping as a way to assess the potential for polluted stormwater discharges. Our staff will always follow up their Compliance Evaluation Inspection with a summary letter to you, restating their findings and, if necessary indicating whether enforcement action will be considered in response to those findings.

Other Information PART IV DEFINITIONS Permit No. NCG120000 PART I INTRODUCTION SECTION A: GENERAL PERMIT COVERAGE All persons desiring to be covered by this General Permit must register with the Division of Water Quality (DWQ) by the filing of a Notice of Intent (NOI) and applicable fees. The N01 shall be submitted and a certificate of coverage issued prior to any point source discharge of stormwater associated with industrial activity to the surface waters of the state. Any owner or operator not wishing to be covered or limited by this General Permit may make application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual permit should be made at least 180 days prior to commencement of discharge. This General Permit does not cover activities or discharges covered by an individual NPDES permit until the individual permit has expired or has been revoked. Any person conducting an activity covered by an individual permit but which could be covered by this General Permit may request that the individual permit be revoked and coverage under this General Permit be provided. If industrial materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion must submit a No Exposure Certification Notice of Intent (NOI) form to the Division; must receive approval by the Division; must maintain no exposure conditions unless authorized to discharge under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually. Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load (TMDL) for pollutants for stormwater is established. A TMDL sets a pollutant -loading limit that affects a watershed, or portion of a watershed, draining to a specific impaired water. For discharges to watersheds affected by a TMDL, coverage under this permit may depend on the facility demonstrating it does not have reasonable potential to violate applicable water quality standards for those pollutants as a result of discharges. If DWQ determines that discharges have reasonable potential to cause water quality standard violations, the facility shall apply for an individual permit 180 days prior to the expiration date of this General Permit. Once that individual permit is effective, the facility will no longer have coverage under this General Permit. During the period beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to discharge stormwater associated with industrial activity. Such discharges shall be controlled, limited, and monitored as specified in this permit. Part I Page 1 of 2 Permit No. NCG120000 SECTION B: PERMITTED ACTIVITIES Until coverage under this permit expires or is modified or revoked, the permittee is authorized to discharge stormwater, to the surface waters of North Carolina or to a separate storm sewer system, which has been adequately treated and managed in accordance with the terms and conditions of this General Permit. Any other point source discharge to surface waters of the state is prohibited unless it is an allowable non- stormwater discharge or is covered by another permit, authorization, or approval. The discharges authorized by this General Permit shall not cause or contribute to violations of Water Quality Standards. Where wetlands are located on or nearby landfilling operations, discharges authorized by this permit and site operations must meet applicable wetland standards, as recorded in 15A NCAC 2B .0230 and .0231, and water quality certification requirements as outlined in 15A NCAC 2H .0500. This permit does not relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree. Part I Page 2 of 2 Permit No. NCG120000 PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES SECTION A: LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGES During the period beginning on the effective date of the Certificate of Coverage and lasting until expiration of the General Permit, the permittee is authorized to discharge stormwater. Such discharges shall be controlled, limited, and monitored as specified below: 1. Prior to commencement of land disturbing activities, the permittee shall submit for approval a Sedimentation and Erosion Control Plan (plan) to the Department of Environment and Natural Resources, Division of Energy, Mineral, and Land Resources, or an approved local program, pursuant to the requirements of NC G.S. 113A-54.1 and in conformity with the rules adopted by the Sedimentation and Erosion Control Commission. 2. The permittee shall implement the approved plan. The approved plan is a requirement or condition of this General Permit. Deviation from the approved plan, or approved amendment to the plan, shall constitute a violation of the terms and conditions of this General Permit. A signed copy of the approved plan shall be maintained on the site at all times. 3. Prior to constructing or operating a landfill the permittee shall obtain a permit for a sanitary landfill from the N.C. Department of Environment and Natural Resources, Division of Waste Management, pursuant to the requirements of NC G.S. 130A - 294 and in conformity with the rules adopted in 15A North Carolina Administrative Code, Subchapter 13B Section .0500 or Section .1600. The landfill permit is a requirement or condition of this General Permit. Deviation from the landfill permit, or approved amendment or revision of the landfill permit, shall constitute a violation of the terms and conditions of this General Permit. A signed copy of the landfill permit shall be maintained on the site at all times. 4. Secondary Containment Requirements and Records. Secondary containment is required for: bulk storage of liquid materials including petroleum products; storage in any amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals; and storage in any amount of hazardous substances, in order to prevent leaks and spills from contaminating stormwater runoff. A table or summary of all such tanks and stored materials and their associated secondary containment areas shall be maintained. If the secondary containment devices are connected to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices, which shall be secured closed with a locking mechanism. Any stormwater that accumulates in the containment area shall be at a minimum visually observed for color, foam, outfall staining, visible sheens and dry weather Flow, prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated by any material. Records documenting the individual making the observation, the description of the accumulated stormwater, and the date and time of the release shall be kept for a period of five (5) years. For facilities subject to a federal oil Spill Prevention, Control, and Countermeasure Plan, facility compliance with any portion of the SPCC plan fully consistent with the requirements of this permit may be used to demonstrate compliance with this permit. 5. Equipment utilized during the land disturbing or landfill operational activities on a site shall be operated and maintained in such a manner as to prevent potential or actual pollution of the surface or ground waters of the state. Fuels, lubricants, coolants, and hydraulic Fluids, other petroleum products, and spent Fluids shall be disposed of in a manner so as not to enter the waters, surface or ground, of the state and in accordance with applicable state and federal disposal regulations. Any Part 11 Page 1 of 6 Permit No. NCG120000 spilled Fluids shall be cleaned up to the extent practicable and disposed of in a manner so as not to allow their entry into the waters, surface or ground, of the state.. SECTION B: ANALYTICAL MONITORING REQUIREMENTS Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All analytical monitoring shall be performed during a measureable storm event at each stormwater discharge outfall (SDO). Only SDOs having stormwater discharges associated with industrial activity must be sampled. See Definitions. A measurable storm event is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72- hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period, and the permittee obtains approval from the local DWQ Regional Office. See Definitions. Table 1 Analytical M nitoring Requirements Discharge Characteristics Units Measurement Fre uenc 1 Sample Type2 Sample Location3 Chemical Oxygen Demand in I semi-annual Grab SDO Fecal Coliform # er 100 ml semi-annual Grab SDO Total Suspended Solids m I semi-annual Grab SDO Total Rainfal14 inches semi-annual Rain gauge Footnotes: 1 Measurement Frequency: Twice per year during a measureable storm event. 2 Sample collection must begin within the first 30 minutes of discharge and continue to all outfalls until completed. 3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative outfall status (ROS) has been granted by DWQ. A copy of the DWQ letter granting ROS must be kept on site. DWQ's ROS letter remains in effect through the subsequent reissuance of this permit and as long as the pertinent site conditions and operations remain unchanged, unless the ROS letter provides for other conditions or duration. 4 For each sampled measureable storm event the total precipitation must be recorded from an on -site rain gauge. (Where isolated sites are unmanned for extended periods, a local rain gauge reading may be substituted for an on -site gauge, upon prior DWQ written approval.) The permittee shall complete the analytical samplings in accordance with the schedule specified in Table 2 below, unless adverse weather conditions prevent sample collection (see Definitions.) Inability to sample because of adverse weather conditions must be recorded on the Discharge Monitoring Report, along with a description of the adverse conditions and their duration. Sampling is not required outside of the facility's normal operating hours. A minimum of 60 days must separate Period 1 and Period 2 sample dates unless monthly monitoring has been instituted via other requirements of this permit. The permittee must report the results of every discharge sample taken within the monitoring period (see Part III, Section E). Failure to monitor semi-annually per permit terms may result in the Division requiring monthly monitoring for all parameters for a specified time period. "No discharge" from an outfall or inability to collect a sample because of adverse weather conditions during a monitoring period, for example, does not constitute failure to monitor, as long as it is properly reported.

The permittee shall compare monitoring results to the benchmark values in Table 3. The benchmark values are not permit limits but should be used as guidelines for the permittee's response actions to control the discharge of pollutants in site stormwater. Exceedances of benchmark values require the permittee to increase monitoring, increase management actions, increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program. Table 3 Benchmark Values for Analytical Monitoring Requirements Discharge Characteristics Benchmark Value Chemical Oxygen Demand 120 m I Fecal Coliform 1000 colonies per 100 ml Total Suspended Solids (TSS) 100 m I TSS ORW, HQW, Trout, and PNA waters 50 m = L Each separate parameter benchmark exceedance triggers a separate tiered response for that parameter at that outfall. See the descriptions of Tier One, Tier Two, and Tier Three response actions below. In the event that DWQ releases the permittee from continued monthly monitoring under Tier Three, DWQ's release letter remains in effect through the subsequent reissuance of this permit, unless the release letter provides for other conditions or duration. Part 11 Page 3 of 6 Permit No.NCG120000 Tier One If: The first valid sampling results are above a benchmark value, or outside the benchmark range, for anv parameter at anv outfall; Then: The permittee shall: 1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling results. 2. Identify and evaluate possible causes of the benchmark value exceedence. 3. Identify the potential, and select the specific: source controls, operational controls, or physical improvements to reduce concentrations of the parameters of concern. 4. Implement the selected actions within two months of the inspection. S. Maintain an on -site record of each instance of a Tier One response. Include the date and value of the benchmark exceedence, the inspection date, the personnel conducting the inspection, the selected actions, and the date the selected actions were implemented. Tier Two If: During the term of this permit, the sampling results are above the benchmark values, or outside the benchmark range, for any specific parameter at a specific discharge outfall two times in a row: Then: The permittee shall: 1. Repeat all the required actions outlined above in Tier One. 2. Immediately institute monthly monitoring for all parameters. Conduct monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample results are below the benchmark values, or within the benchmark range. 3. Submit a monthly monitoring report indicating "No Flow" if no discharge occurs during the sampling period. 4. Maintain a record of the Tier Two response and monitoring results on site. Tier Three During the term of this permit, if the valid sampling results required for the permit monitoring periods exceed the benchmark value for any specific parameter at any specific outfall on four occasions, the permittee shall notify the DWQ Regional Office Surface Water Supervisor in writing within 30 days of receipt of the fourth analytical results. DWQ may, but is not limited to: • require that the permittee revise, increase, or decrease the monitoring frequency for some or all parameters; • rescind coverage under the General Permit, and require that the permittee apply for an individual stormwater discharge permit; • require the permittee to install structural stormwater controls; • require the permittee to implement other stormwater control measures; • require the permittee to perform upstream and downstream monitoring to characterize impacts on receiving waters. Part 11 Page 4 of 6 Permit No. NCG120000 SECTION C: ON -SITE VEHICLE AND EQUIPMENT MAINTENANCE MONITORING REQUIREMENTS Facilities which have any vehicle or equipment maintenance activity occurring on -site which in aggregate uses more than 55 gallons of new motor oil and hydraulic oil per month when averaged over the calendar year shall perform analytical monitoring as specified below in Table 4. All analytical monitoring shall be performed during a measureable storm event at all SDOs which discharge stormwater runoff from the vehicle maintenance areas, in accordance with the schedule presented in Table 2 (Section B.) Table 4 Analytical Monitoring Requirements for On -Site Vehicle Maintenance Discharge Characteristics Units Measurement Fre uenc 1 Sample TypC2 Sample Location3 H standard semi-annual Grab SOO Non -Polar Oil & Grease/TPH EPA Method 1664 SGT-HEM mg/l semi-annual Grab SDO Total Suspended Solids m I semi-annual Grab SDO Total Rainfall4 inches semi-annual Rain gauge New Motor Oil Usage aI month semi-annual Estimate Footnotes: 1 Measurement Frequency: Twice per year during a measureable storm event. 2 Sample collection must begin within the first 30 minutes of discharge and continue to all outfalls until completed. 3 Sample Location: Samples shall be collected at each SDO receiving runoff from vehicle and equipment maintenance areas unless representative outfall status (ROS) has been granted by DWQ. A copy of the DWQ letter granting ROS must be kept on site. DWQ's ROS letter remains in effect through the subsequent reissuance of this permit and as long as the pertinent site conditions and operations remain unchanged, unless the ROS letter provides for other conditions or duration. 4 For each sampled measureable storm event the total precipitation must be recorded from an on -site rain gauge. (Where isolated sites are unmanned for extended periods, a local rain gauge reading may be substituted for an on -.rite gauge, upon prior DWQ written approval.) Monitoring results shall be compared to the benchmark values in Table S. Exceedences of benchmark values require the permittee to increase monitoring, increase management actions, increase record keeping, and/or install stormwater Best Management Practices (BMPs), in accordance with the tiered response provisions of Part 11, Section B.

Readings from an on -site rain gauge must be documented to demonstrate that background concentrations were below the benchmark pl l range of 6-9. Part 11 Page 5 of 6 Permit No. NCG120000 Failure to monitor semi-annually per permit terms may result in the Division requiring monthly monitoring for a specified time period. "No discharge" from an outfall or inability to collect a sample because of adverse weather conditions during a monitoring period, for example, does not constitute failure to monitor, as long as it is properly reported. SECTION D: QUALITATIVE MONITORING AND VISUAL INSPECTION REQUIREMENTS Qualitative monitoring shall be performed twice per year and concurrent with the analytical monitoring requirements in Part 11 Sections B and C for the characteristics listed in Table 6. Qualitative monitoring is for the purpose of quickly evaluating the effectiveness of the stormwater controls. No analytical tests are required. The permittee shall maintain a written record of the qualitative monitoring events on site. Table 6 Qualitative Monitoring Requirements Discharge Characteristics Monitoring Locationl Color SOO Odor SDO Clarity SDO Solids SDO -Floating Suspended Solids SDO Foam SDO Oil Sheen SDO Erosion or deposition at the outfall SOO Other obvious indicators of stormwater pollution SDO Footnote 1: Qualitative monitoring shall be performed at each stormwater discharge outfall (SDO) regardless of representative outfall status (ROS) unless ROS has been granted specifically for qualitative monitoring. A copy of DWQ's letter granting ROS must be kept on site. DWQ's ROS letter remains in effect through the subsequent reissuance of this permit and as long as the pertinent site conditions and operations remain unchanged, unless the ROS letter provides for other conditions or duration. Visual inspections shall be conducted to ensure that all stormwater controls, including all sedimentation and erosion controls, are intact, in good repair, fully functional, and are otherwise being properly implemented. Inspections shall be conducted at least once every seven calendar days, and within 24 hours after any storm event of greater than 0.5 inches of rain per 24 hour period. The permittee shall maintain a written recordof each visual inspection on site. In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall maintain on - site records of both the suspected cause of the condition and the corrective actions taken. If the permittee's qualitative monitoring or visual inspections indicate that existing stormwater controls are ineffective, or that significant stormwater contamination is a recurring condition, the permittee shall investigate potential causes, evaluate the feasibility of corrective actions, and implement feasible corrective actions within 60 days. A written record of the permittee's investigation, evaluation, and response actions shall be kept on site. Records related to qualitative monitoring and visual inspections need only be submitted to DWQ upon the Division's specific request for those records.

The Certificate of Coverage shall expire when the general permit is terminated. Certificate of Coverage Actions The general permit may be modified, revoked and reissued, or terminated for cause. The notification of planned changes or anticipated noncompliance does not stay any general permit condition [40 CFR 122.41(f)]. B. Annual Administering and Compliance Monitoring Fee Requirements The permittee must pay the administering and compliance monitoring fee within 30 (thirty) days after being billed by the Division. Failure to pay the fee in timely manner in accordance with 15A NCAC 211 .0105(b)(2 ) may cause this Division to initiate action to revoke coverage under the general permit. SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of this permit [40 CFR 122.41(e)]. 2. Need to Halt or Reduce Not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this general permit [40 CFR 122.41(c)]. 3. Bypassing of Stormwater Control Facilities Bypass is prohibited and the Director may take enforcement action against a permittee for bypass unless: a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention of stormwater or maintenance during normal periods of equipment downtime or dry weather. This condition is not satisfied if adequate backup controls should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and Part 111 Page 5 of 9 Permit No. NCG120000 c. The permittee submitted notices as required under, Part III, Section E of this general permit. If the Director determines that it will meet the three conditions listed above, the Director may approve an anticipated bypass after considering its adverse effects. SECTION D: MONITORING AND RECORDS Representative Sampling Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Analytical sampling shall be performed during a measureable storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All samples shall be taken before the discharge joins or is diluted by any other waste stream, body of water, or substance. Monitoring points as specified in this general permit shall not be changed without notification to and approval of the Permit Issuing Authority [40 CFR 122.41(j)]. 2. Recording Results For each measurement or sample taken pursuant to the requirements of this general permit, the permittee shall record the following information [40 CFR 122.411: a. The date, exact place, and time of sampling or measurements; b. The individual(s) who performed the sampling or measurements; c. The date(s) analyses were performed; d. The individual(s) who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses. 3. Flow Measurements Where required, appropriate Flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. 4. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136. To meet the intent of the monitoring required by this general permit, all test procedures must produce minimum detection and reporting levels and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of achieving minimum detection and reporting levels below general permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method must be used. 5. Representative Outfall If a facility has multiple discharge locations with substantially identical stormwater discharges that are required to be sampled, the permittee may petition the Director for representative outfall status. If it is established that the stormwater discharges are substantially identical and the permittee is granted representative outfall status, then sampling requirements may be performed at a reduced number of outfalls. 6. Records Retention Part III Page 6 of 9 Permit No.NCG120000 Qualitative monitoring shall be documented and records maintained at the facility. Copies of analytical monitoring results shall also be maintained on -site. The permittee shall retain records of all monitoring information, including o all calibration and maintenance records, o all original strip chart recordings for continuous monitoring instrumentation, o copies of all reports required by this general permit, o copies of all data used to complete the Notice of Intent to be covered by this general permit.
