JAY ZIMMERMAN ENVIRONMENTAL QUALITY - Director August 25, 2016 RECEIVED/NCDENR/DWR Mark Gross AUG 2 9 2016 Alcoa Power Generating Inc Yadkin Division PO Box 576 WQROS Badin, NC 28009-0576 MOORESVILLE REGIONAL OFFICE Subject: NPDES Electronic Reporting Requirements Falls Powerhouse NPDES Permit Number: NCO076775 Dear NPDES Permittee: The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to report information electronically, instead of filing written paper reports. The rule does not change what information is required from facilities. It only changes the method by which information is provided (i.e., electronic rather than paper -based). EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their key milestones, are: Phase 1—Starting on December 21, 2016, regulated entities that are required to submit Discharge Monitoring Reports (DMRs) will begin submitting these reports electronically. If you are currently reporting your DMR data electronically using eDMR, then you simply need to continue reporting in the same way as you are now. The key change is that, starting on December 21, 2016, electronic reporting of DMRs will be required, instead of voluntary. • Phase 2 —Starting on December 21, 2020, regulated entities that are required to submit certain other NPDES reports will begin submitting these reports electronically. Reports covered in the second phase include Notices of Intent to discharge in compliance with an NPDES general permit, Sewer Overflow/Bypass Event Reports, and a number of other NPDES program reports. Incorporating Electronic Reporting Requirements into NPDES Permits The NPDES Electronic Reporting Rule requires authorized NPDES programs to incorporate electronic reporting requirements into NPDES permits beginning December 21, 2015. Under the new rule, the electronic reporting process supersedes the paper reporting process. According to our files, your NPDES permit became effective after November 2013, and should contain the requirement to electronically report your Discharge Monitoring Reports using NC DWR's eDMR system. In addition to requiring permittees to report information electronically; the rule also requires permittees to identify the initial recipient for the NPDES electronic reporting data [see 40 CFR 122.41(I)(9)]. Initiol State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919 807 6300 recipient of electronic NPDES information from NPDES-regulated facilities (initial recipient) means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES Data [see 40 CFR 127.2(b)]. Permittees are required to electronically submit the required NPDES information to the appropriate initial recipient, as determined by EPA. By July 18, 2016, EPA must identify and publish on its web site and in the Federal Register a listing of initial recipients by state and by NPDES data group. Once available, you can use EPA's web site to find out or determine the initial recipient of your electronic submission. NC DWR has submitted a request to EPA to be the initial recipient for the following NPDES data groups: 1. Discharge Monitoring Reports; 2. General Permit Reports [Notices of Intent to discharge (NOls); Notices of Termination (NOTs)]; 3. Pretreatment Program Reports; and 4. Sewer Overflow/Bypass Event Reports EPA's web site will also link to the appropriate electronic reporting tool for each type of electronic submission for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. For more information on EPA's NPDES Electronic Reporting Rule, visit http://www2.epa.gov/compliance/final-national-pollutant-discharge-elimination-system-npdes- electronic-reporting-rule. For more information on electronic reporting to NC DWR, visit http://deg.nc.gov/about/divisions/water-resources/edmr/npdes-electronic-reporting or contact Vanessa Manuel at 919-807-6392 or via email at Vanessa.Manuel@ncdenr.gov.

Box 576 Badin, North Carolina 28009 Dear Mr. Kiser: Division of Water Quality Coleen H. Sullins Director March 30, 2010 Dee Freeman Subject: Permit Reporting Requirements Falls Powerhouse, Narrows Powerhouse, High Rock Powerhouse, and Tucker -town Powerhouse NPDES Permit Nos. NC0076775, NC0081957, NC0081931, and NCO081949 Stanly County This Office recently learned of a contradiction in the Discharge Monitoring Report submission requirements for the above referenced NPDES permits. The Effluent Limitations and Monitoring Requirements section in each permit requires Alcoa to report monitoring results annually based on the calendar year. This reporting schedule is unique to the above referenced permits compared with the 227 other individual NPDES wastewater permits in the Mooresville Region. The annual reporting schedule contradicts the standard reporting conditions for all NPDES permits (Part II Standard Conditions for NPDES permits, Section D Monitoring and Records, Item 2 Reporting), which states , "Monitoring results obtained during the previous month shall be summarized for each month and reported on a monthly Discharge Monitoring Report (DMR) form (MR 1, 1.1, 2. 3) or alternative forms approved by the Director, postmarked no later than the last calendar day of the month following the completed reporting period." Monthly reporting of monitoring data to the Division of Water Quality by NPDES permittees is required by the Clean Water Act and allows for timely response by the Division of Water Quality to permit limit and monitoring violations. To align the Alcoa permits with the remaining individual NPDES wastewater permits within the Mooresville region please adjust your future reporting for the four Alcoa powerhouses to ensure all monitoring data is submitted to the Division within one calendar month of the sampling event. If you have questions Concerning this matter, please do not hesitate to contact Ms. Allocco or me at (704) 663-1699. Sincerely, Robert B.

The Division of Water Quality may pursue enforcement actions for this and any additional violations. If the violations are of a continuing nature, not related to operation and/or maintenance problems, and you anticipate remedial construction activities, then you may wish to consider applying for a Special Order by Consent. You may contact Ms. Marcia Allocco of this Office for additional information. Please note that the reporting of the June 2009 Oil & Grease monitoring did not meet the requirements of your permit. Although Alcoa is only required to monitor for Oil & Grease annually, reporting of monitoring results must be made within one calendar month of the sampling month. Specifically Part II Standard Conditions for NPDES permits, Section D Monitoring and Records, Item 2 Reporting states, "Monitoring results obtained during the previous month shall be summarized for each month and reported on a monthly Discharge Monitoring Report (DMR) form (MR 1, 1.1, 2. 3) or alternative forms approved by the Director, postmarked no later than the last calendar day of the month following the completed reporting period."

A sample was taken on June 3rd 2009 and results received on or about June 13'. The result was 22mg/L and was thought to be in compliance by my staff, within limits of 30-60mg/L. Other permits, i.e. (NC00043080) have this oil and grease limit. While my staff was preparing to complete the Annual DMR for the Falls Powerhouse on November 23rd it was discovered the Daily limit for this permit, oil and grease was actually 20 mg/L and the limit was exceeded. Action has been taken to obtain another sample and my staff will review and revise sampling and reporting procedures to prevent this occurrence in the future.

(APGI) has implemented revised procedures to prevent any future exceedance of the oil and grease limit at Outfall 007 in our Falls Powerhouse NPDES permit NCO076775 dated, 20 August 2009 (Permit). For example, APGI has implemented a new point to collect the sample that is free from surface oil contained in the sump. With respect to the Department's clam in the third paragraph of the NOV that APGI did not adhere to the reporting requirements specified in the Permit for reporting the June 2009 oil and grease sample result, APGI believes that it did adhere to the reporting requirements. Citing Part II, Standard Conditions for NPDES Permits, Section D, Monitoring and Records. Item 2, Reporting, the Department contends that we should have submitted the oil and grease sampling result at the end of the month following the month in which the sample was collected (, at the end of July 2009 in the DMR which summarizes the results of June 2009 sampling). However, under the Notes portion of section A.(2) on page 4 of the Permit which sets forth specific provisions for this Outfall, the Permit reads: "Monitoring results obtained during the calendar year shall be recorded and reported on Discharge Monitoring Report (DMR) form and postmarked no later than January 30fl' following the completed reporting period. Samples obtained for monitoring purposes may be collected anytime during the calendar year." This language was added to the Permit as part of the 30 May 2000 renewal process and has been included in all subsequent permits specifically and expressly to clarify that ArGi was aut 0-1zed to submit annual sampling data by the end of January following the calendar year in which the samples were taken. We are attaching documentation between APGI and the Department supporting this view. Moreover, this specific reporting requirement is consistent with the general provision cited by the Department because the "reporting period" referred to in both provisions ends on December 31 st. Accordingly, APGI believes it has adhered to the reporting requirements in its Permit and desires to continue monitoring and reporting annually as stated therein.

Rex Gleason, P.E. RE. VISIBLE SHEEN REPORTED AT FALLS POWERHOUSE S'✓—i�� f C Q s Gentlemen: As a follow-up to our conversation with Mr. Mike Parker of the Mooresville Regional Office on 2005 October 18, Alcoa is providing the Division of Water Quality with this letter to report an oily sheen which was discovered at the Falls Powerhouse on 2005 September 17. The sheen was discovered during a fatality incident investigation which required the lake level in the Falls Reservoir to be lowered 20 — 25 feet. The sheen was observed in waters adjacent to the electrical substation at the dam. Our investigations have shown that the substation is situated on a fractured rock zone. We believe that small amounts of oil possibly associated with substation activities may have collected over time in this fractured rock„ and that this oil was released through seep holes in the retaining wall situated on the riverbank in front of the substation, resulting in a sheen when the water level in the lake was lowered during the fatality investigation. When the oil and sheen were observed, Alcoa Power Generating, Inc employees placed oil absorbent booms at the water's edge to contain the sheen, and further applied oil absorbent pads to remove the residual sheen that was present. It should also be noted that as a follow-up to this incident there were samples collected of the sediments along the exposed riverbank, as well as, a sample of water dripping from one of the seep holes in the wall which were tested for PCB's. Of seven samples taken, four were non -detect for PCBs. PCBs were observed in the remaining three samples at concentrations of less than 1 mg/kg. Specific results were --_ 2.3_ ug/1_(parts per billion), 49 µg/mg (parts per billion) and 74 µg/mg respectively. Subsequent to the fatality investigation, the water in the Falls Reservoir was returned to normal operating levels. Oil sheens have not been observed in this area since the water level was restored. We believe that any oil that may remain in this area has been contained due to the`lack of a hydraulic gradient as a result of the water being returned to a normal level. It is also our belief that due to 'the coarse nature of the substrate and the small amount of oil observed in the sheen, that the volume of oil in the sii"ce is so small that any oil recovery efforts would serve no useful purpose. In addition to notifying the Mooresville Regional Office, Alcoa also notified the National Response Center and reported the incident to Mr. Threatt who documented the findings as report #776594.

Gen. Stat. § 150B-23 based on actions of the North Carolina Department of Environment and Natural Resources, Division of Water Quality (the "DENR"). w 1. Effective February 1, 2000, the DENR issued to Yadkin an NPDES Permit No. NCO076775 for Yadkin's Falls Powerhouse, located in Stanly County, North Carolina (the "Permit"). A true and correct copy of the permit is attached hereto as Exhibit "A" and incorporated herein as if set forth in full. 2. Pursuant to 15 N.C. Admin. Code §§ 2H .0100-.0111, Procedures for Permits, Approvals for Wastewater Discharges to the Surface Waters (the "Rules"), on October 17, 1999, Yadkin submitted and the DENR subsequently received comments on the draft Permit. A true and correct copy of said comments (the "Comments") is attached hereto as Exhibit `B" and incorporated herein as if set forth in full. 1 It t i 3. The DENR has substantially prejudiced Yadkin's rights and Yadkin hereby appeals the following provisions of the Permit: (1) the pH monitoring requirement for once -through cooling water from outfall(s) serial number 001, 002, 003, 004, and 005; (2) the temperature monitoring requirement for once -through cooling water from outfall(s) serial number 001, 002, 003, 004, and 005; (3) the pH monitoring requirement from outfall(s) serial number 007; (4) the discharge limitation for oil and grease from outfall serial number 007; (5) the reporting requirements for effluent from outfall(s) serial number 001, 0021003, 004, 005 and 007. These provisions are appealed for reasons including, but not limited to, the following: a. The DENR acted erroneously in setting the effective date of the Permit as February 1, 2000, in that the Permit will take effect prior to the expiration'of Yadkin's thirty (30) day appeal period following receipt of the Permit. b. The DENR acted erroneously, failed to use proper procedure and acted arbitrarily and capriciously in setting the pH monitoring requirements for outfall(s) serial number 001, 002, 003, 004, and 005 since Yadkin does not add any chemical additives to the source water. C. The DENR acted erroneously, failed to use proper procedure and acted arbitrarily and capriciously in setting the temperature monitoring requirements for outfall(s) serial number 001, 002, 003, 004, and 005, since the maximum temperature change across the generator is 25°C with a ratio of generator discharge to cooling water discharge of 3,000:1. Therefore, the worst case temperature rise of the Yadkin River due to cooling water discharge would be 0.0083 °C, assuming an ambient water temperature of 20 °C and is well below the 2.8 degree threshold of allowable temperature rise above background. T 1 . d. The DENR acted erroneouslyJailed to use proper procedure and acted arbitrarily and capriciously in setting the pH monitoring requirements for outfall(s) serial number 007 since Yadkin does not add any chemical additives to the source water. e. The DENR acted erroneously, failed to use proper procedure, contrary -to law, and acted arbitrarily and capriciously in setting an unduly burdensome discharge limitation for oil and grease from outfall serial number 007. f. The DENR acted erroneously, failed to use proper procedure and acted arbitrarily and capriciously in setting reporting requirements for effluent from outfall(s) serial number 001, 002, 003, 004, 005 and 007. As stated in the Comments, the DENR has placed overly burdensome, inapplicable and unnecessary reporting provisions in the Yadkin permit, which are not required under similarily situated permits issued pursuant to North Carolina General Permit NC500000. WHEREFORE, Yadkin respectfully requests that this matter be set for a contested case hearing pursuant to the provisions of the N.C. Gen. Stat. § 15013-23. c t ' , , VERIFICATION I, the undersigned first being duly sworn, say that this petition is true to my own knowledge, except as to matters stated on information and belief, and as to those, I believe them to be true.

Hunt, Jr., Governor Bill Holman, Secretary Kerr T. Stevens, Director Mr. William L. McCaskill c/o Yadkin, Inc. P.O. Box 576 Badin, North Carolina 28009 Dear Mr. McCaskill: December 23, 1999 e�� NCDENFX JAN - 7 2000 Subject: Permit No. NCO076775 Falls Powerhouse Stanly County The Division has reviewed the Yadkin Inc. comments of October 17, 1999 in response to their draft NPDES permit. The Division has considered the concerns raised and has modified the permit in accordance with current Division policy, all responses to concerns and revisions made to draft permit, NC0076775, are explained below: Comment #1: Clarification of the pH monitoring requirement, since Yadkin Inc. does not add any chemical additives to the source water. Response: The hydrogen ion content of water is considered a generic measurement of water quality and as such is included as a condition of the general permit for hydroelectric facilities. Since the conditions of the general permit are considered minimum requirements, the semi-annual monitoring of pH, for outfalls 001, 002, 003, 004, and 005 and the quarterly monitoring of outfall 007, will remain as a condition for this permit. Comment #2: Clarification of the temperature monitoring requirement. The maximum temperature change across the generator is 25 °C with a the ratio of cooling water discharge to generator discharge of 1:30,000. Therefore, the worst case temperature rise of the Yadkin River due to cooling water discharge would be 0.0083 °C, assuming an ambient water temperature of 20'C. Response: As with pH, temperature is considered a generic measurement of water quality and as such is included as a condition of the general permit for hydroelectric.facilities. Since the conditions of the general permit are considered minimum requirements, the semi-annual monitoring of temperature will remain as a condition for this permit. Comment #3: Yadkin Inc. request that Discharge Monitoring Reports (DMR) submittal be waived. Response: Since Yadkin, Inc. request coverage under an individual NPDES permit, DMR reporting is required. 1617 Mail service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-5083 FAX (919) 733-0719 An Equal Opportunity Affirmative Action Employer Internet: http://h2o.enr.state.nc.ust Yadkin, Inc. Permit No. NCO076775 Falls Powerhouse Page 2 JComment #4: Since it is impractical to obtain samples at the point of discharge, Yadkin Inc. request approval for sampling at the closest point to discharge where a representative sample can practically be obtained. Response: The Division agrees that this is a reasonable request and has included the phrase, "E — Effluent or the point closest to discharge where a representative sample of the discharge can feasibly be obtained." to allow for sampling at the sump upstream of the discharge. /Comment #5: The cover letter states that the pH limitation will include the phrase "unless ambient river conditions prevent compliance with this range", however this phrase does not appear in the pH footnote. Response: The phrase "unless ambient river conditions prevent compliance with this range" has been inserted into Note 2 on the Effluent Limitations and Monitoring Requirement page. Comment #6: The fact sheet notes that the "facility is not required to perform any instream monitoring". If the boiler plate language relating to increases in stream temperature cannot be removed from the Effluent Limitations and Monitoring Requirements page, then this same statement needs to be reflected on the Effluent Limitations and Monitoring page as a footnote. Response: The temperature footnote contained in the permit is reflective of the water quality standard for temperature as contained in the 02B .0200 rules. Therefore, a discharge cannot raise the temperature of the receiving stream by more than 2.8 °C or cause the receiving stream to exceed 32°C (for lower piedmont and coastal plain waters) even if temperature is not specifically addressed in the conditions of the permit. Though the temperature footnote will remain in the permit, the intent of this limitation is not to require instream monitoring of temperature for reporting purposes. Comment #7: Clarification of BMPs related to the changing of oil absorbent pads on a quarterly basis. Yadkin Inc. does not utilitize oil absorbent pads for the sumps. Instead Yadkin Inc. uses a rope skimmer type oil water separator. Response: Since oil absorbent pads are not utilized at this facility the BUT language has been altered to better reflect the current operations at this facility. BMPs for the rope skimmer type oil/water separator will remain as a condition of the permit. Comment #8 and #9: Yadkin Inc. request that note #1 on the A(2) Effluent Limitations and Monitoring Requirement page be changed to "The tailrace shall be visually inspected for oil sheen attributed to facility operations on a weekly basis in conjunction with inspections of the floor sump and rope skimmer." Additionally, Yadkin Inc. request that note #1 on the A(2) Effluent Limitations and Monitoring Requirement page be replaced with language that requires the tailrace inspections to be logged in the operating log instead of on the DMRs. / Response: The Division recognizes Yadkin Inc.'s concern with the liability of the language contained in J the draft permit and has no objection to the proposed language, however in order to assure the availability of data, the footnote has been modified as follows: "The tailrace shall be visually inspected for oil sheen attributed to facility operations on a weekly basis in conjunction with inspections of the floor sump and rope skimmer. Confirmation that a visual inspection was conducted shall be recorded in the operating log for the facility and provided to the Division upon request."

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS -i During the period beginning on the effective date of the permit and lasting until expiration, the Permittee is authorized to discharge from outfall(s) serial number 007 — Sump Drain. Such discharges shall be limited and monitored by the Permittee as specified below: , , ,, ., • , • NOTES: * Sample Locations: E — Effluent or at the point closest to discharge where a representative sample of the discharge can feasibly be obtained. 1 The tailrace shall be visually inspected for oil sheen attributed to facility operations on a weekly basis in conjunction with inspections of the floor sump and rope skimmer. Confirmation that a visual inspection was conducted shall be recorded in the operating log for the facility and provided to the Division upon request. 2. The pH of the effluent shall not be less than 6.0 standard units or greater than 9.0 standard units, unless ambient river conditions prevent compliance with this range. Best Management Practices (BMPs) must be employed to ensure that excessive pollutants are not discharged to the surface water of the state. These practices should include as a minimum, routine maintenance of the rope skimmer type oil/water separator and cleaning accumulated sediment in the bottom of the sump annually. Chemical wheel pit cleaning is permitted on a monthly basis. When wheel pit cleaning occurs, the tailrace shall be inspected visually for foam and oil. Cleaning shall. be conducted only with pre -approved solvents. Should the Permittee wish to change solvents, a written request should be made to. the Division including the MSDS for the proposed solvent. s.

Concentration Measurement a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit. b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled. and/or measured during a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the -arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average weekly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If only one sample is taken during any calendar day. the concentration of pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Part I of the permit. d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily. discharges sampled and/or measured during a calendar year on which daily- discharges are sampled and measured divided by the number of daily discharges sampled and/or measured 'during :such .year:_(arithmetic mean of the .daily concentration values). The daily,concentration value is equal to the concentration of a composite sample or in the case'of- grab samples is the arithmetic mean (weighted by' flow -value), of all. the samples collected during that calendar` day : 'The average yearly, - count for fecal.coliform•bacteria is the geometric mean of the counts for samples collected during a calendar year.; ,TThis limitation is identified as "Annual Average" under "Other Limits" in Part I of the permit. e. The "daily average concentration" (for dissolved oxygen) _is the minimum allowable amount of dissolved oxygen required to 'be available in the effluent prior to discharge'averaged over a calendar day. If only one dissolved oxygen sample is taken over a' calendar day, the. sample is considered to be the "daily average concentration" for the discharge.

Permit No. NC0076775 Falls Powerhouse Page 3 Comment #10: Yadkin request that the "Boiler Plate language related to the discharge of floating solids or visible foam be removed from the Effluent Limitations and Monitoring Requirements page. Foam is not uncommon on the downstream side of the hydroelectric plant, however this foam is due to turbulence and surfactants or other foam causing agents present in the ambient river water. Response: The Division agrees that Yadkin Inc. cannot control the characteristics of the influent ambient river water, therefore the phrase "unless ambient river conditions prevent compliance" has been added to the language. Comment #11: Effluent Limitations and Monitoring Requirements page for outfalls 001, 002, 003, 004, and 005: The monitoring frequency for these outfalls is semi-annual, however the reporting frequency is quarterly. Yadkin Inc. request that the reporting frequency mirror the monitoring frequency for these outfalls. Response: The quarterly monitoring frequencies for these outfalls were placed in the draft permit in order to maintain consistency throughout the permit. This was done as a matter of convenience to the Division and the permittee. However, the Division recognizes the permittee's concerns over the liability of this requirement and has changed the reporting requirement to mirror the monitoring frequencies. Attached is the NPDES permit No. NC0076775 issued December 23, 1999. 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 US Environmental Protection Agency dated December 6, 1983.

BOX 576 BADIN, NC 28009 Subject: NPDES PERMIT NO. NCO076775 STANLY COUNTY Dear Permittee: The subject permit issued on 12/23/92 expires on 8/31/94. North Carolina General Statute (NCGS) 143-215.1(c) requires that an application for permit renewal be filed at least 180 days prior to the expiration date. As of the date of this letter, the Division of Environmental Management had not received an application for renewal. If operation of a discharge or waste treatment facility is to occur after the permit's expiration date, or if continuation of the permit is desired, it must not be allowed to expire. A renewal request must be submitted no later than 180 days prior to the permit's expiration date. Operation of the waste treatment works or continuation of a discharge after the expiration date would constitute a violation of NCGS 143-215.1 and could result in assessment of civil penalties of up to $10,000 per day. If continuation of the permit is desired, failure to request renewal at least 180 days prior to expiration will result in a civil assessment of at least $250.00; larger penalties may be assessed depending upon the delinquency of the request. A renewal application shall consist of the following information: 1. A letter requesting the renewal. 2. The completed application form (copy attached), signed and submitted in triplicate, referenced in Title 15 of North Carolina Administrative Code (15A NCAC) Subchapter 2H .0105(a). 3. A processing fee (see attached schedule) in accordance with 15A NCAC 2H .0105(b). The application processing fee is based on the design or permitted flow, whichever is appropriate, listed in the first categories of facilities. 4. Primary industries listed in Appendix A of Title 40 of the Code of Federal Regulations, Part 122 shall also submit a priority pollutant analysis in accordance with'Part 122.21. 1 5. Facilities which have not been constructed within the last permit cycle and are therefore, considered "new" facilities, shall also submit an Engineering Alternatives Analysis, referenced in 15A NCAC Subchapter 2H .0103 and Subchapter 2B .0201(c). 6. If the facility covered by this permit contains some type of treatment works, a narrative description of the sludge management plan must be submitted with the application for the renewal. In addition to penalities referenced above, a permit renewal request received after the expiration date will be considered as a new application and will require the higher application fee. 15A NCAC 2H .0105(b)(2) requires payment of an annual Administrative and Compliance Monitoring fee for most permitted facilities. You will be billed separately for that fee (if applicable), after your permit is approved. The letter requesting renewal, the completed Permit application, and appropriate fee should be sent to: Permits and Engineering Unit Division of Environmental Management Post Office Box 29535 Raleigh, North Carolina 27626-0535 The check should be made payable to the North Carolina Department of Environment, Health, and Natural Resources which may be abbreviated as DEHNR.
