Klimek, P.E., Director Division of Water Quality June 10, 2005 Mr. Gary O. Smith II WWTP Superintendent Post Office Box 190 Albemarle, North Carolina 28002-0190 Subject: NPDES Permit Issuance Permit NC0024244 City of Albemarle WWTP Stanly County Dear Mr. Smith: Division personnel have reviewed and approved lour application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge 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 May 9, 1994 (or as subsequently amended.) The following modifications to the permit have been made since the March 16, 2005 draft permit: • The monitoring frequency for upstream color monitoring has been changed to 2/month to coincide with the effluent and downstream color monitoring frequency. • The instrumented effluent flow measurement has been corrected to the instrumented influent flow measurement. • A centrifuge and a batch feed indirect heat sludge dryer have been added to the treatment components of the facility. • The Division, in consultation with EPA has agreed to a variance of the 85 percent removal requirement for Total Suspended Solids (TSS). Based on review of influent and effluent data, the monthly average effluent TSS concentration shall not exceed 18 percent of the respective influent value (82 percent removal) in the summer months (April 1 through October 31) and shall not exceed 32 percent of the respective influent value (68 percent removal) in the winter months (November 1 through March 31).

The reasonable potential analysis indicated that an effluent limit was no longer required. Cadmium will continue to be monitored quarterly in the Pretreatment Program's Long Term Monitoring Plan. • Summer and winter weekly average limits for ammonia nitrogen have been added to reflect the Division's current policy. The weekly average limit is established based on a ratio of 3:1 (weekly average: monthly average) for municipal dischargers. The corresponding weekly average limits for ammonia nitrogen at the flow of 16.0 MGD are 6.0 mg/1 for the summer and 12.0 mg/1 for the winter. • A total residual chlorine limit of 18 ug/1 has been added to reflect the Division's current policy for protection against instream chlorine toxicity. The limit for total residual chlorine shall become effective upon completion of the installation of a disinfection system but no later than 18 months from permit issuance. If a method different than chlorination/dechlorination is used, the total residual chlorine limit will not be applicable. See Part I. A. (2.) of the permit. • A daily maximum limit of 5.3 1.4/1 was included for Cyanide. A limit was necessary because the reasonable potential analysis indicated that the maximum predicted concentration was greater than the allowable concentration. • A daily maximum limit of 0.012 µg/1 was included for Mercury. A limit was necessary because the reasonable potential analysis indicated that the maximum predicted concentration was greater than the allowable concentration. • A daily maximum limit of 5.3 µg/1 was included for Selenium. A limit was necessary because the reasonable potential analysis indicated that the maximum predicted concentration was greater than the allowable concentration. If Albemarle has twelve (12) consecutive months of cyanide, mercury, and/or selenium values below the detection levels, then the City may submit a written request asking DWQ to re-evaluate the assignment of the limits in the NPDES permit. 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. Permit NC0024244 City of Albemarle WWTP Page 3 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, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be final and binding. Please notice that this permit is not transferable. Part II, E.4. 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 permits may be required.

Permit NC0024244 SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A. (2.) TOTAL RESIDUAL CHLORINE The limit for total residual chlorine shall become effective upon completion of the installation of a disinfection system but no later than 18 months from the issuance of the permit (January 1, 2007). If a method different than chlorination/dechlorination is used, the total residual chlorine limit will not be applicable. A. (3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 90%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of March, June, September, and December. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised - February 1998) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months, in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: NC DENR / DWQ / Environmental Sciences Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. Permit NC0024244 SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A.. (4.) COLOR REOPENER AND MONITORING REQUIREMENTS This permit will be modified or revoked and reissued to incorporate color limitations and /or revised monitoring requirements in the event color testing or other studies conducted by the permittee or the Division indicate that color has rendered or could render the receiving waters injurious to public health, secondary recreation, to aquatic life and wildlife or adversely affect the palatability of fish, aesthetic quality or impair the water for any designated use. Color monitoring should consist of ADMI monitoring as specified below. All samples taken should have complete descriptive recordings of the color in the sample container including hue (distinctive characteristics and tint), clarity (clearness of the color sample) and luminance (brightness or glowing quality) of the sample as it looks in the collection container. Descriptions of stream color should also be recorded when color samples are collected. Color samples should be analyzed as follows: ➢ At natural pH; ➢ Free from turbidity (true color); and ➢ Samples shall be analyzed in accordance with the provisions of Method 2120.E.4 as described in the 18th edition of Standard Methods for the examination of Water and Wastewater. Using a narrow -band scanning spectrophotometer to produce a COMPLETE spectral curve of the visible spectrum (350-750 nm), calculate and report results in ADMI values for true color values at the samples ambient pH value. All color data including visible observations should be submitted with the monthly DMRs.

DENR Division of Water Quality NPDES Unit 1617 Mail Service Center Raleigh, NC 27699-1617 SUBJECT: Requests for modifications Draft NPDES Permit Perm it NC0024244 City of Albemarle WWTP Stanly County Dear Ms. Nowell: I am writing you this letter in response to our conversation we had on April 28, 2005. During the conversation you pointed out effluent data detections for Selenium, Cyanide, and Mercury in previously submitted DMRs. I agree with your findings and cannot find any evidence to discredit this data. The mercury data may be questionable as it states a number at the detection level but not less than. However, I do request that the monitoring frequency be reduced from weekly to monthly for each of these parameters. For each of these parameters you pointed out one excursion that led to including a daily maximum limit in our NPDES permit. Analyzing these parameters on a weekly basis will cost approximately $7,000 annually. That seems quite a penalty for one excursion in the last 4 years. If comparison influent sampling is conducted, then the cost doubles to $14,000 annually. I do not feel this fair and it is probably more costly than if we were fined. Also, 1 would like to propose that if 12 consecutive months of effluent data shows no detection of these parameters, that the limits be removed for these parameters and monitoring revert back to Long Term Monitoring Plan frequencies. If you have any questions feel free to contact me at (704) 984-9630, by fax (704) 984-9629 or e-mail garvsmith .ci.albemarle.nc.us. Your consideration in this matter will be greatly appreciated.

The data shows how much lower the % TSR removal is in the winter months. The summer months show a higher removal percent but still do not consistently meet the 85% removal criteria. Based on the information shown, NCDWQ recommends that for the winter months (November 1 through March 31), Albemarle must meet a percent removal limit of 68%. For the summer months (April 1 through October 31), we recommend that they must meet a percent removal limit of 82%. The data indicates that while the summer removal numbers have improved above the permitted 62% percent removal limit, the low influent TSR values are a hindrance to meeting the 85% removal.. A review of the earlier file sent to you with the removal data will show more clearly that the influent TSR numbers for the Albemarle WWTP are drastically lower than typical municipal wastewater. Our recommendations are based on the average of the percent removal for the summer and winter months for the years 2001 through 2004. Based on this information we recommend the continuance of the variance for the % removal for TSR to the recommended 68% for the winter months and 82% for the summer months. Please review and contact me with your opinion. Thanks, Jackie Nowell 1 of 1 5/5/2005 2:44 PM about:blank Hello Gary, We are still in the process of reviewing the removal data and determining what we will do. I have a time set up on Monday to talk with my supervisor to discuss all the Albemarle issues. I did receive your written comments last week and am also reviewing them. Regarding your comments on the metals, I used effluent and long term monitoring data to do my analysis. There were reported values, along with a multiplication factor that is applied, that indicated these metals may have the potential to exceed the permit limit. In order to run the analysis, we need at least twelve data values. If a metal is only sampled quarterly, we would have to go back three years to get the twelve data points for a valid analysis, therefore data in year 2002 could be used. For example with 1) Cyanide, since its sampled in the LTMP, we had to go back a couple of years to get twelve values - there was a reported value of 30 ug/1 in March 2002. That is the value that indicated a reasonable potential to exceed the permit limit. 2) Selenium - a reported value of 6.2 ug/1 in June 2004. While the only value above detection, it was a fairly recent reported value and indicated potential to exceed the permit limit. 3) Mercury - a reported value of 0.2 ug/1 in August 2003 indicated potential to exceed the permit limit. If there is a question as to whether the data value is valid, ie lab error or something, it must be documented and supported by the lab. Based on the data above, effluent limits were proposed for the metals in question. Smith, Gary wrote: Jackie, I received your voice mail concerning the TSR Removal. I understand what you are saying and will hope that you can be as lenient as possible when setting the required TSR percent removal for the permit. Another reason I am writing this e-mail to you, is to make sure you received my comments and requests for modifications of the draft NPDES Permit NC0024244.

[49 FR 37006, Sept. 20, 1984; 49 FR 40405, Oct. 16,1984] § 133.103 Special considerations. (a) Combined sewers. Treatment works subject to this part may not be capable of meeting the percentage removal requirements established under §§ 133.102(a)(3) and 133.102(b)(3), or §§ 133.105(a)(3) and 133.105(b)(3) during wet weather where the treatment works receive flows from combined sewers (i.e., sewers which are designed to transport both storm water and san- itary sewage). For such treatment works, the decision must be made on a case -by -case basis as to whether any attainable percentage removal level can be defined, and if so, what the level should be. (b) Industrial wastes. For certain industrial categories, the discharge to navigable waters of BODS and SS per- mitted under sections 301(b)(1)(A)(i), (b)(2)(E) or 306 of the Act may be less stringent than the values given in §§ 133.102(a)(1), 133.102(a)(4)(i), 133.102(b)(1), 133.105(a)(1), 133.105(b)(1) and 133.105(e)(1)(1). In cases when wastes would be introduced from such an in- dustrial category into a publicly owned treatment works, the values for BOD5 and SS in §§ 133.102(a)(1), 133.102(a)(4)(i), 133.102(b)(1), 133.105(a)(1), 133.105(b)(1), and 133.105(e)(1)(i) may be adjusted upwards provided that: (1) The §133:103 §1 permitted discharge of such pollutants, ME attributable to the industrial category, lin would not be greater than that which me would be permitted under sections eel 301(b)(1)(A)(1), 301(b)(2)(E) or 306 of the me Act if such industrial category were to me discharge directly into the navigable ha' waters, and (2) the flow or loading of str such pollutants introduced by the in- ery dustrial category exceeds 10 percent of do the design flow or loading of the pub- cox licly owned treatment works. When not such an adjustment is made, the values ter for BOD5 or SS in §§ 133.102(a)(2), cer 133.102(a)(4)(11), § 133.102(b)(2), exc 133.105(a)(2), 133.105(b)(2), and exc 133.105(e)(1)(ii) should be adjusted pro- plu portionately. flo' (c) Waste stabilization ponds. The Re- the gional Administrator, or, if appro- plu priate, State Director subject to EPA lon approval, is authorized to adjust the (E minimum levels of effluent quality set wal forth in § 133.105 (b)(1),. (b)(2), and (b)(3) wet* for treatment works subject to this or, part, to conform to the SS concentra- aut tions achievable with waste stabiliza- per tion ponds, provided that: (1) Waste loaf stablization ponds are the principal reqi process used for secondary treatment; §§ 1: and (2) operation and maintenance data 13� indicate that the SS values specified in 133. § 133.105 (b)(1), (b)(2), and (b)(3) cannot vid4 be achieved. The term "SS concentra- den tions achievable with waste stabiliza- wor tion ponds" means a SS value, deter- con mined by the Regional Administrator, con or, if appropriate, State Director sub- rem ject to EPA approval, which is equal to due the effluent concentration achieved 90 was percent of the time within a State or mom appropriate contiguous geographical wor area by waste stabilization ponds that can, are achieving the levels of effluent cent quality for BOD5 specified in reqt §133.105(a)(1). [cf. 43 FR 55279]. star (d) Less concentrated influent waste- infli water for separate sewers. The Regional fron Administrator or, if appropriate, State clea Director is authorized to substitute ei- ing ther a lower percent removal require- min ment or a mass loading limit for the cent percent removal requirements set forth cess in §§ 133.102(a)(3), 133.102(a)(4)(iii), CFB 133.102(b)(3), 102.105(a)(3), 133.105(b)(3) critf and 133.105(e)(1)(iii) provided that the ita permittee satisfactorily demonstrates inch that: (1) The treatment works is con- sistently meeting, or will consistently valu 491 § 133.104 40 CFR Ch. 1 (7-1-02 Edition) meet, its permit effluent concentration limits but its percent removal require- ments cannot be met due to less con- centrated influent wastewater, (2) to meet the percent removal require- ments, the treatment works would have to achieve significantly more stringent limitations than would oth- erwise be required by the concentra- tion -based standards, and (3) the less concentrated influent wastewater is not the result of excessive I/I. The de- termination of whether the less con- centrated wastewater is the result of excessive I/I will use the definition of excessive 1/1 in 40 CFR 35.2005(b)(16) plus the additional criterion that in- flow is nonexcessive if the total flow to the PO°TW (i.e., wastewater plus inflow plus infiltration) is less than 275 gal- lons per capita per day. (e) Less concentrated influent waste- water for combined sewers during dry weather. The Regional Administrator or, if appropriate, the State Director is authorized to substitute either a lower percent removal requirement or a mass loading limit for the percent removal requirements set forth in §§ 133.102(a)(3), 133.102(a)(4)(iii), 133.102(b)(3), 133.105(a)(3), 133.105(b)(3) and 133.105(e)(1)(iii) pro- vided that the permittee satisfactorily demonstrates that: (1) The treatment works is consistently meeting, or will consistently meet, its permit effluent concentration limits, but the percent removal requirements cannot be met due to less concentrated influent wastewater; (2) to meet the percent re- moval requirements, the treatment works would have to achieve signifi- cantly more stringent effluent con- centrations than would otherwise be required by the concentration -based standards; and (3) the less concentrated influent wastewater does not result from either excessive infiltration or clear water industrial discharges dur- ing dry weather periods. The deter- mination of whether the less con- centrated wastewater results from ex- cessive infiltration is discussed in 40 CFR 35.2005(b)(28), plus the additional criterion that either 40 gallons per cap- ita per day (gpcd) or 1500 gallons per inch diameter per mile of sewer (gpdim) may be used as the threshold value for that portion of the dry weath- er base flow attributed to infiltration. If the less concentrated influent waste- water is the result of clear water indus- trial discharges, then the treatment works must control such discharges pursuant to 40 CFR part 403.

The current permit contains a total suspended solids percent removal requirement of 62%, which we view as a waiver from the secondary treatment requirements at 40 Code of Federal Regulations Section 133.103. That waiver has been carried over and retained in the draft permit. Based on our review, insufficient information has been provided to justify continuance of that waiver in the draft permit. Because the information provided is inadequate to determine whether the draft permit meets the guidelines and requirements of the Clean Water Act, I request that data regarding influent and effluent levels of this parameter and other documentation sufficient to justify a special consideration and waiver under 40 Code of Federal Regulations Section 133.103 be provided. Pursuant to federal regulatory requirements and language of Section VII.A. of the North Carolina/EPA National Pollutant Discharge Elimination System (NPDES) Memorandum of Agreement (MOA), this letter constitutes an interim objection to the issuance of this permit. In accordance with the MOA and federal regulations, the full period of time for review of this draft permit will recommence when the requested information is received by this Office. I look forward to receipt of the information. If you have any questions, please call me or have your staff contact Mr. Marshall Hyatt at 404/562-9304. Sincerely, ames D.

EPA would like to review their plan of study and implementation plan. He also said to let CMU know that if the WER indicates that more stringent limits should be applied, then CMU would be bound by the results. They cannot decide not to accept the results. 3) Also ok with more stringent NH3 limits. So, I can proceed to finalize the CMU permits . y1Ppl act 5U 2 (LNovirid-6I WOUL.11 NMt6 ib Alfr v-*J2- Afuµa.-a- Albemarle --- He recognizes that Albemarle has a problem, influent TSS values are as low as he's ever seen. But he thinks there is a seasonal component to their problem, the winter months,esp. Feb. and March are when they have the problem. He has a two fold recommendation for us to ponder -- 1) Continue with a % removal less that 85% but not as low as 62% because he doesn't think that 62% is warranted.. He looked at the average cYo removal from 2001 -2004 and by his calculations it was 80%, 75%, 63%, 81%, respectively. the average of the 4 years was 75%. We could think about what we would recommend. 2) make the variation of the % removal for basically the winter months only since those appear to be the problem times. We could designate what the winter months would be. Then come up with what percent removal we would allow for those months. I told him that I don't think that last option had ever been done, but that I would consult with staff and get back with him. the first option to increase % removal from 62% up to some number is the easiest thing to do. The winter only option will take some more work. Do you have a sagely recommendation? Uci 13A11AT,15 Do A 9 G -.")Tl L& on.)

After review of this document, there are several concerns about how these new additional requirements will impact the City of Albemarle. The following is a summary of objections and comments on the new changes incorporated in the proposed permit: Item 1. Daily Maximum Limits for Selenium, Cyanide, and Mercury Many of these objections will be nearly the same as I stated in August 2000. The above -mentioned items have never been limited in past NPDES permits. What is the rationale for issuing limitations on these parameters at this time? The City of Albemarle has passed the Chronic Toxicity requirement consistently over the past few years. The letter states these limits are proposed due to "the reasonable potential analysis." Again I ask, what data is this analysis based on? The data the City of Albemarle has collected for Mercury is not extensive. The discharge limit of 0.013 ug/1 of Mercury is below the detection level of 0.2 ug/1 that has been reported by this facility for the majority of the data collected since 2001. Using the new low-level mercury technique Albemarle has not reported any effluent values near the discharge limit; the greatest value reported being 0.00889 ug/l. , , a , _ o, Z J 4) The accuracy of laboratory results for Cyanide at the 5.3 ug/1 discharge limit is very questionable. I understand several other municipalities have raised this topic. Looking over the data obtained between 2001-2004, I have seen two instances were the City would have exceeded the limits for Cyanide. However, I question the accuracy of these results, due to their respective influent values. There has been no detection of Selenium in the effluent since 2001 and I cannot recall any detection prior to that date either. - U . Z 1- The City feels there is not significant evidence to issue Daily Maximum Limits for Selenium, Cyanide, and Mercury. The City of Albemarle requests that the Daily Maximum Limits for Selenium, Cyanide, and Mercury be removed from the proposed NPDES Permit. The City of Albemarle proposes that monitoring be continued for the above -mentioned parameters as listed in the Long Term Monitoring Plan. If monitoring should indicate problems then limits may be in order. Item 2. Total Residual Chlorine Limit The City of Albemarle objects to a Total Residual Chlorine Limit, but is aware that this is now policy for all dischargers. Albemarle has a very crude and antiquated dechlorination system that is not adequate to completely dechlorinate during high flow situations at the facility. Viewing past DMRs one will notice that during high flow situations Albemarle WWTP normally discharges some residual chlorine. This doesn't occur during normal flow conditions. This condition was never thought to be a critical issue in the past, since during high flow situations the receiving stream flow was very high as well and the discharge should be little or no impact. It is mentioned in the cover letter for the draft NPDES permit that the chlorine limit shall become effective no later that 18 months from permit issuance. The City of Albemarle requests that the chlorine limit not become effective until 18 months after permit issuance. The 18 months should give the City enough time to budget and install improvements to the dechlorination system so it can handle high flow situations. Item 3. Color (ADMI) Monitoring Requirements This is an error that was not picked up in Albemarle's existing NPDES permit. The reason being that the cover letter submitted with the existing NPDES permit stated the instream monitoring frequency for Color was the same as the previous NPDES permit. The Upstream and Downstream3 measurement frequency for Color (ADMI) should be 12/month)to coincide with Effluent monitoring frequency for Color. C✓ (. %/ ( 2 Item 4. Items in Supplement to Permit Cover Sheet The following win items should be deleted: Dissolved -air flotation ' s (destroyed in great flood in 1997) and Instrumented effluent flow measurement (should be influent).

In Part A.1, recommend changing "total suspended residue" to "total suspended solids" in both the table and footnote #2. 2. re Hg, shouldn't the permit require use of Method 1631E? If so shouldn't the sample type be grab? 3. re footnote #2, the 38 % removal limit for TSS appears to be rolled over from the previous permit. Such a waiver must be re -demonstrated at each permit renewal. The fact sheet contains no rationale or any demonstration required by 40 CFR Part 133.103 for renewal of this waiver from secondary treatment requirements in the reissued permit. W/o such a valid rationale based on some section of 40 CFR Part 133.103, EPA will object to its inclusion. 1 of 1 4/11/2005 2:33 PM Draft Permit Review Subject: Draft Permit Review From: John Giorgino <j ohn.giorgino @ ncmail.net> Date: Wed, 23 Mar 2005 15:55:37 -0500 To: Jackie Nowell <Jackie.Nowell@ncmail.net> Hi Jackie, I have reviewed Permit #NC0024244, City of Albermarle.

City of Albemarle Wastewater Treatment Plant, NPDES Permit Number NC0024244, Stanly County, has applies fro renewal of its permit discharging treat- ed wastewater to the Long Creek in the Yadkin River Basin. Currently BOD5, NH3, Dissolved Oxygen, total residual chlorine, fecal coliform and other parame- ters are water quality limited. This dis- charge may affect future allocations in this portion of the receiving stream. March 20, 2004 Fact Sheet - NPDES Permit Long Creek WWTP NPDES No. NC0024244 Facility Receiving Stream Facility Name: City of Albemarle — Long Creek WWTP Receiving Stream: Long Creek Permitted Flow (MGD): 16.0 MGD Subbasin: 030713 Facility Class: IV Index No.: Facility Status: Existing Stream Class: C Permit Status: Renewal 303(d) Listed: No County: Stanly Use Support: Regional Office: Mooresville Drainage Area (mi2): 64 USGS Topo Quad: F18SW Summer 7010 (cfs) 1.6 Winter 7010 (cfs): 9.5 30Q2 (cfs): 4.7 Average Flow (cfs): 64 IWc (%): 94 FACILITY OVERVIEW The facility is currently permitted for 16 MGD. The wastewater treatment system consists of the following components: > Mechanical bar screens > Dual gravity grit chambers > Influent lift station > Parshall flume with instrumental flow measurement > Preaeration basins ➢ Primary clarifiers > Trickling filters ➢ Mechanical aeration basins > Secondary clarifiers ➢ Gravity tertiary filters > Chlorination and dechlorination > Instrumented effluent flow measurement > Twelve in -plant screw lift pumps > Aerobic digesters > Dissolved -air flotation units and > Sludge holding tanks The facility serves the City of Albemarle (-15500 persons), Stanly County (-2800 persons) and the Town of New London (-275 persons). City of Albemarle has a full pre-treatment program with a Long Term Monitoring Plan and has 4 SIUs (Significant Industrial Users) and 1 CIU (Categorical Industrial User) per its application. Permit NC0050903 RECEIVING STREAM The City of Albemarle — Long Creek WWTP discharges treated municipal and industrial wastewater to Long Creek in the Yadkin -Pee Dee River basin. The stream classification of this segment of the Long Creek is C. The receiving stream has a use rating of Supporting. Instream monitoring is required for temperature, dissolved oxygen, conductivity and color. There is a discrepancy about the frequency of the instream monitoring. MRO staff noted that the facility will probably request modification of the frequency to reflect the requirements in the 1994 permit. Current instream monitoring sites are as follows —as in the November 1, 2000 permit: Upstream above the discharge point Downstream) = Downstream at the end of NCSR 1960 Downstream2 = Downstream 3.9 miles at NCSR 1967 Downstream3 (for color samples only) = approximately 200 yards downstream from the discharge point Upstream and downstream samples shall be grab samples. Stream samples shall be collected once per month in the winter (October through May) and once per week during the summer (June through September.) Review of instream data showed that in 2003 and 2004, the dissolved oxygen standard of 5 mg/1 was met at all stations upstream and downstream of the WWTP. However, in 2001 and 2002, there were summer months where upstream and downstream instream DO averages were below the standard of 5 mg/1. Based on this data, we recommend that the instream monitoring frequency remain at once per week in the summer and once per month in the winter. .---Instream color data There has been a reduction in the color in ADMI detected downstream of the discharge. However, there is still apparent color in the stream, therefore we recommend continuation of the instream color monitoring program. TOXICITY TESTING Type of Toxicity Test: Chronic P/F Existing Limit: 001: Chronic P/F @ 90% Recommended Limit: 001: Chronic P/F @ 90% Monitoring Schedule: March, June, September, and December The facility had passed all quarterly toxicity tests from March 2000 until March 2003, when there was a failure. The follow-up test was late, but was followed by two Passes. Since June 2003, the facility has passed all toxicity tests. COMPLIANCE HISTORY The Town appears to have had an excellent compliance record for the past three years with minimal violations. In 2002, all permit limitations were met. In 2003, all permit limitations were met with the exception of two BODS violations in April and May and a TSS exceedance in March and a toxicity failure in March. Through November 2004, all permit limitations are being met. 2 Permit NC0050903 REASONABLE POTENTIAL ANALYSIS The following metal parameters are limited or monitored in the NPDES permit: Chromium, Cadmium, Copper and Zinc. Data for the following parameters was reported in the discharge monitoring reports and a RPA was also done: As, Cd, Cr, Cu, Cn, Pb, Hg, Ni, Se, Ag, and Zn. The facility is under a full pretreatment program. Reasonable potential analysis was conducted based on data from 2001 through 2004. Results and data analysis are attached. RPA RESULTS: Based on the Reasonable Potential Analysis: (See attached results) • Limits should be deleted for cadmium based on RPA. Cadmium results had eighty one (81) reported values and all were below detection. There was no reasonable potential to exceed the allowable concentration. The weekly average and daily maximum limit can be removed. Quarterly monitoring for cadmium, will be applied. • Limits for cyanide, mercury and selenium should be added based on the RPA. The results for these three constituents had max. predicted values that exceeded the allowable concentrations. All showed reasonable potential to exceed the allowable concentrations. . • 2/ month monitoring for copper and zinc should be continued in the permit. RPA results showed the maximum predicted value exceeding the allowable action level concentration. • • Limit for chromium of 53 ug/1 should continue to be included in the permit. The parameter showed reasonable potential to exceed the allowable effluent concentration. • Results of the RPA for arsenic, lead, nickel and silver showed no reasonable potential for exceedance of allowable concentrations. No limits or monitoring for these parameters are needed. PROPOSED CHANGES • Addition of daily maximum limits and/or weekly average limit for cyanide, mercury and selenium. • Deletion of weekly average and daily maximum limits for cadmium. • Summer and winter weekly average limits for ammonia nitrogen have been added to the permit, based on DWQ procedure for all NPDES dischargers. • The addition of a TRC limit of 18 ug/1 based on DWQ procedure. Facility will be given an 18 month compliance schedule to meet the limit. PROPOSED SCHEDULE FOR PERMIT ISSUANCE: Draft Permit to Public Notice: March 16, 2005 (est.)

River Basin and Subbasin No.: Yadkin 030713 c. Describe receiving stream features and pertinent downstream uses: Flow was observed in the receiving stream (8-10 feet wide x 6-10 inches deep) at the time of the site inspection. Downstream uses are primarily for secondary recreation and agriculture. IWC = 1.6 cfs PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. a. Volume of Wastewater: 16.0 MGD (Design Capacity) b. What is the current permitted capacity: 16.0 MGD c. Actual treatment capacity of current facility (current design capacity): 16.0 MGD d. Date(s) and construction activities allowed by previous ATCs issued in the previous two years: There have been no ATCs issued in the past two years. e. Description of existing or substantially constructed WWT facilities: The existing WWT facilities consist of four mechanical bar screens followed by two gravity grit chambers, an influent lift station, a parshall flume with instrumented flow measurement, two preaeration basins, four primary clarifiers, four trickling filters, four mechanical aeration basins, four secondary clarifiers, a gravity tertiary sand filter, a chlorine contact basin, sodium bisulfite disinfection, instrumented effluent flow measurement, two aerobic digestors, and two sludge holding tanks. The existing dissolved air flotation (DAF) units are inoperable and should be removed from the permit. f. Description of proposed WWT facilities: There are no proposed WWT facilities at this time. g• Possible toxic impacts to surface waters: Generally, this facility has a very good compliance record for toxicity (one failure in the past four years). h. Pretreatment Program (POTWs only): Approved. 2. Residual handling and utilization/disposal scheme: a. If residuals are being land applied specify DWQ Permit No. WQ0002616 Residuals Contractor: City of Albemarle Telephone No. (same as above) b. Residuals stabilization: PSRP 3. Treatment Plant Classification: Class IV Page Three 4. SIC Code(s): 4952 Wastewater Code(s): 55, 01, 59 MTU Code(s): 01103 PART III - OTHER PERTINENT INFORMATION 1. Is this facility being constructed with Construction Grant Funds or are any public monies involved (municipals only)? The WWT facilities were constructed with public monies. 2. Special monitoring or limitations (including toxicity) requests: . . The City's current NPDES allowed for removal of the Cadmium (Cd) limit after one year if the City collects 12 consecutive months of data that reflects Cd levels below detection levels. Although the City had sufficient Cd monitoring data during the term of the current permit to make such a request, none was ever submitted. Based on conversations with City personnel during the site visit, a request to remove the Cd monitoring requirement will be submitted as an addendum to the permit renewal. In anticipation of the addition of a TRC limit being added to the new permit upon renewal, a Schedule of Compliance should be included in the draft permit to allow for the additional construction necessary for the City to comply with the TRC requirement. There is a discrepancy in the way the instream monitoring frequencies are defined in the current permit. The permit issued to the City on December 1, 1994 had the following instream monitoring frequencies and locations: Sample locations: E - Effluent, I - Influent, U - Upstream above the discharge point. D = D1 & D2 (should also have included D3), D1 - Downstream at the end of NCSR 1960. D2 - 3.9 miles below discharge at NCSR 1967; D3 - Downstream approximately 200 yards below discharge. Upstream and downstream samples shall be grab samples. Stream samples shall be collected once per month in the winter (October through May) and once per week in the summer (June through September) at the upstream site and D2. Weekly monitoring shall be conducted during the summer (June through September) at Di. The current NPDES permit (issued November 1, 2000) defined instream monitoring locations and frequencies in this manner: Upstream = Upstream above the discharge point. Downstreaml = Downstream at the end of NCSR 1960. Downstream2 = Downstream 3.9 miles at NCSR 1967. Downstream3 (for color samples) = approximately 200 yards downstream from the discharge point. Upstream and downstream samples shall be grab samples. Stream samples shall be collected once per month in the winter (October through May) and once per week in the summer (June through September). Page Four The City recognized this discrepancy in the draft of the 2000 permit and advised the Divison in a letter dated August 21, 2000. The Division responded in a cover letter attached to the November 1, 2000 permit that the instream monitoring frequencies had been revised to reflect the 1994 permit, however, this was not the case as noted above. The City will again be requesting (as an addendum to the current renewal application) that the instream monitoring frequencies be reflective of those listed in the 1994 NPDES permit. 3. Important SOC/JOC or Compliance Schedule dates: This facility is neither under an SOC/JOC nor is one being considered at this time. PART IV - EVALUATION AND RECOMMENDATIONS The City of Albemarle requests renewal of the subject permit. There have been no changes or modifications to the existing WWT facilities or the permit since the permit was last renewed. Requested changes to the permit, which should be forthcoming from the City are addressed in Part III, No. 2 above. Pending receipt and approval of the draft permit, it is recommended that the NPDES Permit be renewed as requested.

Colored discharges are generally not toxic. Potential toxicity is managed by the regulation of specific chemical constituents and by WET testing (see Section ) The primary issue in the regulation of color is the aesthetic quality of receiving waters and the implication of this aesthetic quality for the designated uses of those waters. The practical application of the above regulation must take into account the various ways in which color manifests itself in the environment. Color in natural waters is rarely the result of one specific chemical. Rather, a mixture of many dissolved and suspended constituents contributes to color. The stream bed and sediments may also contribute to color. Because color is perceived differently by different people and in different light conditions, no general definition of color impairment can be specified by a simple set of criteria and enforcement of the current narrative color standard can be very subjective. In the Broad basin, discharges with a high degree of color come primarily from certain industrial facilities and from municipal dischargers receiving highly colored industrial effluent. While colored effluent can be discharged by a number of industries, textile firms constitute the most significant source of color in the Broad basin. Division staff have researched the implementation of a numeric standard, or a set of numeric water quality standards. The Division would prefer, however, that dischargers remove color on their own initiative. If such efforts are not successful, the Division may proceed with the development of a numeric color standard. In order to address the problem of discolored waterbodies and to assist facilities that are attempting to reduce color in their effluent, the Division is developing a statewide voluntary program in cooperation with the Division of Pollution Prevention and Environmental Assistance (DPPEA). The program will focus on reducing the discharge of colored wastewater from textile manufacturing and related industries, with a goal of reducing instream color to the point where color -related complaints for surface waters are nonexistent. The program will be based on bui a cooperative network between p g � facilities with highly colored effluent and a "mentor" group. The mentors will include color removal experts, textile industry associations, facilities that are already implementing color removal, and DEHNR staff members. Although color in itself is not a toxicant, dischargers removing color from their effluent may receive the added benefit of reducing salts, BOD and metals. DWQ and DPPEA staff are currently involved in data collection and the evaluation of various color removal proposals. Statewide workshops and conferences will be held in early 1998 to publicize the effort and obtain feedback on the design of the program. 114. Aii--/A/dose/r- t-e— /if/ /k�z � Ave-44/-
