Sullins Dee Freeman Director Secretary September 4, 2009 S E P 0 9 2009 BY: Subject: Final NPDES Stormwater Permit Permit NCS000530 Carolina Marine Terminal Alamance County In response to your renewal application for continued coverage under NPDES stormwater permit NCS000530, the Division of Water Quality (Division) is forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215 .1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection agency dated October 15, 2007 (or as subsequently amended). This final permit includes two minor change from the draft permit sent to you on June 16, 2009. Section B includes the line "This individual permit does not allow discharges determined by the Division of Water Quality to be wastewaters." By recommendation of the Wilmington Regional Office, the monitoring schedule has been modified. The first sample must be taken before November 30, 2009. The schedule then returns to a sample required every six months. I received written comments from McKim&Creed on the draft permit in a letter dated July 15, 2009. The letter has concerns about the analytical monitoring because the parameters are not based on an established TMDL. However, the analytical monitoring in the permit is based on potential stormwater pollutants and the analytical data submitted in the application. The letter states there are concerns about the "benchmark" monitoring because of the variability of the parameters and materials shipped through the marine terminal and question the benchmark the reliability of a benchmark where exceedances trigger more monitoring. Again, the monitoring in the permit is for potential pollutants and more monitoring is only triggered after the benchmarks have been exceeded two times. The letter indicates that vehicle maintenance occurs onsite but under covered or protected areas whenever possible. The question is asked if the activity will trigger the special circumstances listed. The vehicle maintenance section will apply to the facility if there are any vehicle maintenance activities occurring on -site which use more than 55 gallons of new motor oil per month when averaged over the calendar year regardless if the activities occur under cover or not. The letter states that Carolina Marine utilizes covered storage whenever possible and that product is preserved. We understand that Carolina Marine works to keep a clean site and minimize product lose. We encourage these practices and feel that it will help with compliance of their permit.

McCarley Carolina Marine Terminal Permit No. NCS000530 %r , The letter proposes developing a continuing study to establish pollutant levels in the stormwater discharge. While we feel this would be helpful, we also feel the permit monitoring is set to provide data about the stormwater. The benchmark values in the permit are not effluent limits and provide a standard guidance for determining pollutant concentration levels of concern for stormwater. The Toxicant benchmarks are based on one half the Final Acute Value (1/2 FAV). NC DENR uses the 1/2 FAV to set daily maximum wastewater limits for toxicants in conjunction with weekly average limits. The FAV is estimated by statistical analysis of acute toxicity -data and protects 95 percent of the species in the most sensitive genera that has been tested. A safety factor of two is applied for water quality protection purposes. Some of the other parameters are based on secondary treatment regulations such as BOD and COD. pH is based on the water quality standard. While more data would be helpful in understanding the poIIutants in the stormwater, the data would not affect the benchmark values. The written comments show concerns of a potential poIIutant source under River Road. We encourage indentifying the source and responsible parties. Your written comments request a site meeting to discuss the permit provisions. Linda Willis conducted a site visit on December 10, 2008. We have worked closely with her on writing the permit and feel a site visit is not necessary. We agreed to a site visit on August 26, 2009 but the visit was canceled and to be rescheduled. Carolina Marine Terminal then informed us that no site visit was necessary and they would wait for the permit to be issued. Please note that analytical monitoring is required in this permit. Failure to complete the monitoring as required is a violation of the permit and any permit noncompliance constitutes a violation of the Clean Water Act. Reference Part III, Section A, Item 2 "Duty to Comply", Item 9 "Penalties for Tampering " and Item 10 "Penalties for Falsification of Reports" of your permit for further information. If any parts, measurement frequencies or sampling'requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611 -7447. Unless such demand is made, this decision shall be final and binding. Please take notice this permit is not transferable. Part III, B.2. addresses the requirements to be followed in case of change in ownership or control of this discharge. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources, Coastal Area Management Act or any other Federal or Local governmental permit that may be required. 2 'Mr. Michael E.

STORMWATER POLLUTION PREVENTION PLAN The Permittee shall develop a Stormwater Pollution -Prevention Plan, herein after referred to as the Plan. This Plan shall be considered public information in accordance with Part III, Standard Conditions, Section E, Paragraph 3 of this general permit. The Plan shall include, at a minimum, the following items: Site Plan. The site plan shall provide a description of the physical facility and the __ potential pollutant sources which may be expected to contribute to contamination of stormwater discharges. The site plan shall contain the following: (a) A general location map (USGS quadrangle map or appropriately drafted equivalent map), showing the facility's location in relation to transportation routes and surface waters, the name of the receiving water(s) to which the stormwater outfall(s) discharges, or if the discharge is to a municipal separate storm sewer system, the name of the municipality and the ultimate receiving waters, and accurate latitude and longitude of the point(s) of discharge. The general location map (or alternatively the site map) shall identify whether each receiving water is impaired (on the states. 303(d) list of impaired waters) or is located in a "watershed for which a TM )L has been established, and what the parameter(s) of concern are. (b) A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or particulate generating or control processes, and waste disposal practices. A narrative description of the potential pollutants which could be expected to be present in the stormwater discharge from each outfall. (c) A site map drawn to scale (including a distance legend) showing: the site property boundary, the stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial activity areas (including storage of materials, disposal areas, process areas, loading and unloading areas, and haul roads), site topography, all drainage features and structures, drainage areas for each outfall, direction of flow in each drainage area, industrial activities occurring in each drainage area, buildings, existing BMPs, and impervious surfaces. The site map must indicate the percentage of each drainage area that is impervious. (d) A list of significant spills or leaks of pollutants that have occurred at the facility during the three (3) previous years and any corrective actions taken to mitigate spill impacts. (e) Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. The certification statement will be signed in accordance with the requirements found in Part III, Standard Conditions, Section Part II Page I of I Permit No. NCS000530 B, Paragraph 5. The permittee shall re -certify annually that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. 2. Stormwater Management Plan. The stormwater management plan.shall contain a nafrative description of the materials management practices employed which control or minimize the exposure of significant materials to stormwater, including structural and nonstructural measures. The stormwater management plan, at a minimum.' shall incorporate the following: (a) Feasibility Study. A review of the technical and economic feasibility of changing the methods of operations and/or storage practices to eliminate or reduce exposure of materials and processes to stormwater. Wherever practical, the permittee shall prevent exposure of all storage areas, material handling operations, and manufacturing or fueling operations. In areas where elimination of exposure is not practical, the stormwater management plan shall document the feasibility of diverting the stormwater runoff away from areas of potential contamination. (b) Secondary Containment Requirements and Records. Secondary containment is required for: bulk storage of liquid materials; 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), and 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 years. (c) BMP Summary. A listing of site structural and non-structural Best- Management Practices (BMP) shall be provided. The installation and implementation of BMPs shall be based on the assessment of the potential for sources to contribute significant quantities of pollutants to stormwater discharges and data collected through monitoring of stormwater discharges. The BMP Summary shall include a written record of the specific rationale for installation and implementation of the selected site BMPs. The BMP Summary shall be reviewed and updated annually. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or the team) responsible for implementing the SPRP shall be identified in a written list incorporated into the SPRP and signed and dated by each individual acknowledging their responsibilities for the plan. A responsible Part 11 Page 2 of 1 1 r - Permit No. NCS000530 person shall be on -site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore; an oil Spill Prevention Control and Countermeasure plan (SPCC) may be'a component of the SPRP, but may not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be incorporated by reference into the SPRP. 41 Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping program shall be developed. The program shall list all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial activity areas (including material storage areas, material handling areas, disposal areas, process areas, loading and unloading areas, and haul roads), all drainage features and structures, and existing structural BMPs. The program shall establish schedules of inspections, maintenance, and housekeeping activities of stormwater control systems, as well as facility equipment, facility areas, and facility systems that present a potential for stormwater exposure or stormwater pollution. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. Timely compliance with the established schedules for inspections, maintenance, and housekeeping shall be recorded in writing and maintained in the SPPP. 5. Employee Training. Training programs shall be developed and training provided at a minimum on an annual basis for facility personnel with responsibilities for: spill response and cleanup, preventative maintenance activities, and for any of the facility's operations that have the potential to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the training shall be identified, and their annual training shall be documented by the signature of each employee trained. b. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific position(s) responsible for the overall coordination, development, implementation, and revision to the Plan. Responsibilities for all components of the Plan shall be documented and position assignments provided. 7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in design, construction, operation, or maintenance which has a significant effect on the potential for the discharge of pollutants to surface waters. All aspects of the Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual update shall include an updated list of significant spills or leaks of pollutants for the previous three years, or the notation that no spills have occurred. The annual update shall include written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Each annual update shall include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management Plan. The Director may notify the pennittee when the Plan does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the permittee shall Part II Page 3 of 11 Permit No. NCS000530 submit a time schedule to the Director for modifying the Plan to meet minimum requirements. The permittee shall provide certification in writing (in accordance with Part I11, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been made. 8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual schedule, once during the first half of the year (January to June), and once during the second half (July to December), with at least 60 days separating inspection 'dates (unless performed more frequently than semi-annually). These facility inspections are different from, and in addition to, the stormwater discharge characteristic monitoring required in Part II B and C of this permit. 9. Implementation. The permittee shall implement -the Plan. Implementation of the Plan shall include documentation of all monitoring, measurements, inspections, maintenance activities, and training provided to employees, including the log of the sampling data and of actions taken to implement BMPs associated with the industrial activities, including vehicle maintenance activities. Such documentation shall be kept on -site for a period of five years and made available to the Director or the Director's authorized representative immediately upon request. Part 11 Page 4 of 1 1 Permit No. NCS000530 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 representative storm event. The required monitoring will result in a minimum of ten analytical samplings being conducted over the term of the permit at each stormwater discharge outfall (SDO). A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time between this storm event and the previous storm event measuring greater than 0.1 inches must be at least 72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if it rains but stops before producing any collectable discharge,_a sample may be collected if the next rain producing a discharge begins within 10 hours. - Table 1.

The Division will consider the monitoring results in determining -whether additional BMPs are needed to control the pollutant(s) of concern to the maximum extent practicable. If additional BMPs are needed to achieve the required level of control, the permittee will be required to (1) develop a strategy for implementing appropriate BMPs;-and (2) submit a timetable for incorporation of those BMPs into the permitted Stormwater Pollution Prevention Plan. SECTION C: QUALITATIVE MONITORING REQUIREMENTS Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of representative outfall status and shall be performed as specified in Table 4, during the analytical monitoring event. [If analytical monitoring is not required, the permittee still must conduct semi- annual qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the effectiveness of the Stormwater'Pollution Prevention.Plan (SPPP) and assessing new sources of stormwater pollution. In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall document the suspected cause of the condition and any actions taken in response to the discovery. This' documentation will be maintained with the SPPP. Table 4. Qualitative Monitoring Requirements Discharge Characteristics Frequencyl Monitoring Location2 Color semi-annual SDO Odor semi-annual .
