BALLARD ST. — P.O. BOX 428 WYLIE,TEXAS 75098 (214)442-2236 May 20 , 1986 Charles D . Gill , District Manager District IV Texas Water Commission 208 James Collins Elvd . Duncanville , Texas 75116 Dear Mr . Gill : The City of Wylie is in receipt of a letter from your office dated May 14 , 1666 wherein you make reference to an annual compliance inspection of the City of W'ylie ' s wastewater treatment plant permit No . WQ00103 4-UD1 . It is our intention to respond in detail to the comments offered in that letter within the period ( 45 days ) specified . The purpose of this letter is to acknowledge receipt of your letter and return initial comments to some of your remarks . Your letter begins by noting deficiencies in Section A ,which are labeled " Wastewater Treatment Plant Maintenance" . These comments number 1 through 6 . In addition , your office comments deficiencies in the "wastewater treatment plant operation" your Section B and these comments number 1 throuch 8 . While you personally may not be aware of this , the City wishes to inform your office that while the City knows and understands that it retains legal responsibility for the operation of this plant and it ' s compliance with all laws . We do have a contract with North Texas Municipal Water District for the operation and maintenance of that plant . Therefore , I shall share these comments with the Council of the City of Wylie as well as forward a copy of this correspondence to NT,i'UD for their response . It is our position that they and they alone are responsible for the deficiencies in this area . Under your comments Section C " Industrial Waste Honitorin end Enforcement " , numbers 1 through S , the City offers these initial comments . The City of ! ylie passed it ' s first wastewater control ordinance in 1 5% 2 . As was the case at the time , this ordinance dealt almost exclusively with heavy metals and was not a modern ordinance of any type at all . In July 1965 , the City passed a modern wastewater and water pollution control and abatement ordinance . The first step 1 in applying this ordinance has been to distribute questionaires to the local businesses and potential polluters for their voluntary response . This step has been taken . In addition , the City is contacting several chemical testing laboratories to make arrangements for acceptable samples to be taken so that they may be used as part of our enforcement program . It was necessary for us to locate and contract with a private firm since NTMWD , the body who normally does our testing , refuses to appear in court to testify about the results of their analyses . Once these steps are completed , your office will see an effective enforcement program . In item 2 of this section , you list a troublesome grab sample in the SOD was high . In the second part of that paragraph , you talk about " new connections , increased flows , or significant changes " causing a change in the influent quality which apparently relates to the high BOD you mentioned earlier . It is our belief that the high BOD ' s are a result of blood entering the system from three potential sources . None of these sources are new . All of our growth has been almost exclusively in standard housing producing ordinary domestic wastewater . In addition , we are curious why this change has not been reflected in the monthly reports for the operation of the plant . lie :an only assume that the sewage treatment plant is effectively dealing with this problem or the reports are in error . In Section D System Bypasses , you note an incidence where an overflow occured not a bypass which implies intent . In that section , you speak of a grab sanple and your concern about Muddy Creek . As a result of this incident , an earthen dam was erected around the tanks which would automatically return any future occurance of this nature back into the tanks and would not allow any physical means by which this discharge could enter Muddy Creek . Further in the paragraph you speak about our obligations to notify you concerning any discharge . It is my understanding that this has been done promptly and to an extent to which I have never seen in any community that I have served prior to this . Of particular interest to me was the fact that a bypass was done by NTiiUD and was reported to your office . It is my belief that this bypass was intentional and was reported to your field representative along with a sample of what hhdT ' ''ID claimed was a back-wash . It should be noted that this back-wash 2 contained raw sewage . I was an eye witness to this incident along with several other people who .Jouid be happy to testify . Yet I find no mention of this incident in the report . In item 2 of that section , you discuss the reviewing authority rights of the Texas Water Commission . I would like to point out that none of our system improvements have participation by Federal or State agencies . They are financed exclusively with local funds , developers costs or charged fees . In addition , while this requirement is , I believe , being unusually enforced , we have complied and have submitted all of our plans for lift stations and sewer lines to the appropriate authorities , many of them have been returned approved . We have had no indication that any of our improvements will not be acceptable . In Section E you discuss a troublesome grab sample . We are curious why a grab sample is fine here when your own rules seem to indicate a preference for composite s =_nples . be are also curious how we have been able to pre _uce such good reports . In Section F , you make comment concerning several design deficiencies of the plant . These comments will be forwarded to NTiNWd for their response , for it is a requirement of their contract that they notify us of any alterations or improvements that may need to be made from time to time in the plant . I an enclosing a copy of that agreement as well as several other documents . You should be aware that the City of ylie has advertised for consultant engineering services for modifications to it ' s existing plant and design of a new wastewater plant to meet more nocern treatment guideline_ using current technology . have narrowed that process down to the final three firms . These firms are CH2W1 Hill , Brown & Caldwell and Riewe & Wischneyer . The City was prepared to select one of these firms and begin the design phase . However , we have responded to a request from NTi:'bD that has delayed that process . In Section G , you comment about a report that is missing . I will be happy to inform bT1UD that you require this -. eport . You attached a letter dealing with the temporary lift station . That lift station was placed by a developer and we have always admitted it did not meet the standards . The City has since replaced this temporary station .Jitin a system that does meet the design criteria . This same comment eculd be appropriate to the letter that you attache dated January 1oc . I trust that these comments , which will be ._ ' ared with the City Council , NTL:CD , your district office a^ d Austin will provide some initial response to your corimelts while we oeepare a much more lengthy and technical response . In addition , it is my belief that many of these problems will be solved within that period since that process was already at work . Please contact this office shoule you require clarification of any of these preliminary comments . l/2 ------' G s H . Pap771 City iianag GHP : bl cc : Rex McDonnell , Jr . , P .

Operating Responsibility. It is the intent of this agreement that the operation of the plant shall be the responsibility of the District and that the plant shall be operated in a manner that will provide a water quality conforming to the waste control order issued by the Texas Water Quality Board, or any subse- quent order issued relating to this plant. 2. Financing. The olant is presently owned by the City, and it shall be City's responsibility to provide such facilities, operating funds, and capital expenditures as are necessary to accomplish the quality of discharge stipulated in the waste control order issued by the Texas Water Quality Board, or any subse- quent orders. At an appropriate time and under terms agreeable to both parties City will transfer ownership of the plant to District in order that it may be incorporated in a regional system. 3. Operating Budget. The District shall prepare an annual operating budget reflecting all anticipated costs In connection with the operation of the plant in sufficient detail to justify expenditures for salaries, materials, supplies and contractual services. The proposed operating budget shall be sub- mitted to City on or before August I of each year. If no protest or request for a hearing on the Budget is not presented prior to September I , the proposed Budget, on adoption by the District, shall be considered the "Annual Budget" for the ensuing fiscal year. In the event City and District are not able to agree on the operating budget prior to October I , the budget for the previous year shall apply for the first 60 days of the new fiscal year, with adjustments only to those items that are agreed to by City. If, at the end of this 60 day period, no agreement has - 2 - been reached on the operating budget this contract shall be terminated in accordance with the termination provisions herein provided. In first year a budget will be prepared for a full twelve ( 12) months with payments based thereon, but on the next October a new Budget will be imple- mented and fiscal year shall thereafter be October I to September 30 of each year. 4. Annual Charges. Monthly payments shall be made by City equal to the total operating budget divided by 12, and these payments shall be made in advance on or before the 10th day of each month. The first monthly payment due October 10 of each year shall be twice the calculated monthly payment with no payment due in September of each year except for any adjustments previously approved by City. At the end of each fiscal year any surplus balance would be carried forward to reduce the overall cost during the next budgetary period. Emergency expenditures not budgeted may be incurred with the concurrence of the District's Executive Director and the City's City Manager, subject to limitations placed on each by respective governing bodies, with appropriate adjust- ments in monthly payments. Routine requests for adjustments in monthly payments must receive prior approval by the City. In the event the City shall fail to make any monthly payment by the 20th day of the month in which due, after notice to City, the District may termi- nate service as of the first day of the following month. 5. Additional Connections. District may provide service to other munici- palities subject to approval of City, and the charge which is levied for such ser- vice shall include adequate compensation to the City for its capital investment as well as operating expenditures. . 6.

Box 428 MAY 1 91986 Wylie, Texas 75098 � " RE: The Wylie Wastewater Treatment Plant Annual Compliance Inspection Permit No. WQ0010384-001 Dear Mayor Hughes: On March 13, 1986 and April 4, 1986, our representative, Mr. Forrest B. John, conducted an annual compliance inspection of the City of Wylie Wastewater Treatment Plant (WWTP) and Collection System. During the inspection, numerous deficiencies were noted and are itemized below for your convenience. A. Wastewater Treatment Plant Maintenance 1 . The wastewater treatment- plant lift station pumps were leaking due to faulty packing. 2 . The surface of the clarifier was covered with a layer of sludge. Activated sludge was washing over the clarifier weirs . 3 . On the date of the inspection, no chlorine residual was present in the plant effluent. Solids, from recurrent plant upsets, accumulate in the chlorine contact basin and enter chlorinators with make-up water. This results in the chlorinators becoming clogged. 4 . Approximately half of the chlorine contact basin surface was covered with a sludge blanket. Due to sludge in the basin, solids were washing out of the basin with the effluent. 5 . One of the two sludge return pumps was in need of repair. 6 . Valving at the diversion box, ahead of the effluent pipe, was deteriorated to a point where the valves can no longer be opened or closed. B. Wastewater Treatment Plant Operation 1 . Sludge disposal records are not being maintained. REPLY TO: DISTRICT 4 / 203 JAMES COLLINS BLVD. / DUNCANVILLE,TEXAS 75116 AREA CODE 214/298-6171 P.O.Box 13087 Capitol Station • Austin,Texas 78711 • Area Code 512.463-7898 City of Wylie Permit No. WQ0010384-001 May 14, 1986 Page 2 2 . For self-reporting purposes, the effluent has been sampled by the individual grab samples rather than the required 3-part composite sample. The Texas Administrative Code 329 . 9 (a) Table 1 , 0 . 50 - 1 .0 MGD, Design Capacity, states : "The laboratory test shall be made on a composite sample made up of three proportions collected no closer together than 2 hours and with the first sample collected no earlier than 10 :00 a.m. " 3 . Improper removal of solids from the chlorine contact basin. C. Industrial Waste Monitoring and Enforcement Program 1 . City of Wylie industrial waste monitoring and enforcement is nonexistant. 2 . The influent wastewater individual grab sample, collected March 26, 1986 , analytical results are as follows: (a) pH (standard units) 7 .7 * (b) Biochemical Oxygen Demand 1,053 (c) Total Suspended Solids (mg/1) 185 *Typical Biochemical Oxygen Demand (5-day) values for untreated domestic wastewater are approximately 250 mg/l . Item 1 . (d) under "General Conditions" , of Permit No. WQ0010384-001 states : "d. Any change in the facility discharge, including any new significant discharge or significant changes in the quantity or quality of existing discharges to the treatment system that will result in new or increased discharges of pollutants must be reported to the permitting authority. Modifications to the permit may then be made to reflect any necessary changes in permit condi- tions , including any necessary effluent limitations for any pollutants not identified and limited herein. In no case are any new connections, increased flows, or sig- nificant changes in influent quality permitted that will cause violation of the effluent limitations specified herein. " 3 . The City of Wylie has failed to monitor industrial waste discharges into the sanitary sewer system while fully cognizant that the industrial discharges were having a direct and detri- mental impact upon the wastewater treatment plant. City of Wylie Permit No. WQ0010384-001 May 14 , 1986 Page 3 D. The Wastewater Treatment Plant Collection System and Collection System Bypasses 1 . On March 13 , 1986 , the Texas Water Commission District 4 Office received an anonymous complaint of alleged frequent wastewater bypasses occuring at the Southfork Mobile Home Park Addition. In response, on March 26 , 1986 , Mr. Forrest B. John of this office conducted an on-site investigation accompanied by Mr. W. W. Windham, City of Wylie Director of Public Works . During the investigation, what appeared to be a recent wastewater bypass from the wastewater holding tank at the Southfork Mobile Home Park was observed. The discharge flowed to an unnamed tributary of Muddy Creek located approximately 250 feet northeast of the wastewater holding tanks . A grab sample was obtained. Analytical results of the grab sample are as follows: (COC Tag No. IN 17344) a. pH (standard units) 8 . 3 b. Biochemical Oxygen Demand (mg/1) 128 c . Total Suspended Solids (mg/1) 100 d. Ammonia-Nitrogen (NH3-N) , (mg/1) 23 . 30 The results of the grab sample confirms that the suspected wastewater exhibited the typical composition of untreated domestic wastewater. Therefore, unreported wastewater bypass appears to have occured that entered the unnamed tributary of Muddy Creek. The District 4 Office has advised the City of Wylie, by letter on two previous occasions (September 1985 and January 9 , 1986 copies attached) of reporting procedures for wastewater bypasses . Please be advised that Chapter 26 . 039 (b) , 26 .121 (a) and 26 .126 (a) and (b) of the Texas Water Code states: 26 .039 (b) "Whenever an accidental discharge or spill occurs at or from any activity or facility which causes or may cause pollution, the individual opera- ing, in charge of, or responsible for the activity or facility shall notify the commission as soon as possible and not later than 24 hours after the occurence II 26 . 121 (a) "Except as authorized by a rule, permit or order issued by the commission, no person may: (1) discharge sewage, municipal waste, recreational waste, agricultural waste, or industrial waste into or adjacent to any water in the state; (2) discharge other waste into or adjacent to any water in the state which in itself or in conjunction with any other discharge or acitivity causes, continues to cause, or will cause pollution of any of the water in the state; or City of Wylie Permit No. WQ0010384-001 May 14 , 1986 Page 4 (3) commit any other act or engage in any other activity which in itself or in conjunction with any other discharge or activity causes, continues to cause, or will cause pollution of any of the water in the state, unless the activity is under the jurisdiction of the Parks and Wildlife Department, the General Land Office, or the Railroad Commission of Texas, in which case this subdivision does not apply. " 26 .126 (a) If a person violates this chapter or a rule or order adopted or a permit issued under this chapter, the commission may assess a civil penalty against that person as provided by this section. (b) The penalty may be in an amount not to exceed $10, 000 a day for a person who violates this chapter or a rule, order, or permit. Each day a violation continues may be considered a separate violation for purposes of penalty assessment. " In addition, the City of Wylie, Texas Water Commission Permit No. WQ0010384-001, Item 11, under "General Conditions" states : "The permittee shall within 72 hours notify the permit issuing authority in writing of each unauthorized diver- sion or bypass in accordance with the procedure specified for reporting noncompliance. " 2 . The Wyndham Estates and Southfork Mobile Home Park Collection systems have not been approved by the Texas Department of Health. Please be advised that the Texas Administrative Code Chapter 317 .1 (a) (2) and 317 .1 (a) (3) (F) state: 317 .1 (a) (2) Reviewing Authority. The Texas Water Code places the responsibility with the Texas Water Commission for review of plans and specifications for construction projects funded by the Texas Water Quality Enhancement Fund. The commission will also review all plans for projects which may receive United States Environmental Protection Agency financial assistance under the Construction Grants Program The Texas Department of Health will review all plans and specifications for work that is not eligible for federal or state financial assistance, and for all projects that are funded exclusively under Farmers Home Administration, Economic Development Administration, and Department of Housing and Urban Development. The Texas Water Commission and the Texas Department of Health are hereinafter referred to as the Reviewing Authority for projects within their respective jurisdiction. City of Wylie Permit No. WQ0010384-001 May 14 , 1986 Page 5 317 .1 (a) (3) (F) Changes or Alterations. When changes are planned for existing systems, notification to the reviewing authority shall be made and shall include sufficient information to describe the significance of such modifications . The reviewing authority will determine whether engineering plans and specifications will be required following this initial notification of the extent of the planned modifications . " In addition, Item 4 , under "Other Requirements" of Permit No. WQ0010384-001 states : "4 . The plans and specifications for the waste collection and treatment works associated with the discharge authorized by this permit must be approved pursuant to state law, and failure to secure approval before commencing construction of such works or making a discharge therefrom is a violation of this permit and each day of discharge is an additional violation until approval has been secured. " E. Noncompliant Effluent Individual Grab Sample During the April 4, 1986 inspection, an effluent individual grab sample was obtained and the analytical results are as follows : 1 . pH (standard units) 7 . 3 2 . Ortho-Phosphates (mg/1) 4 .01 *3 . Total Suspended Solids (mg/1) 320 4 . Ammonia-Nitrogen (mg/1) 2 . 75 *5 . Biochemical Oxygen Demand (mg/1) 85 6 . Nitrates (mg/1) 0 .13 7 . Nitrites (mg/1) 0 . 216 *Item l.a . , under "Other Requirements" states: "Each pollutant concentration in a grab sample in excess of the value shown for such pollutant in Column 2 of Table 1 constitutes a violation of the permit. " Table 1 Pollutant Column 1 Column 2 BOD5 mg/1 35 65 Suspended Solids mg/1 35 65 F. Wastewater Treatment Plant Design Deficiencies On August 19 , 1985, the District 4 Office notified the City of Wylie by letter of design deficiencies that exist at the wastewater treatment facilities . Since that date, many of . City of Wylie Permit No. WQ0010384-001 May 14 , 1986 Page 6 The same design deficiencies remain and are as follows: (a) Oxidation Ditch The Texas Administrative Code Chapter 317 . 4 (h) (1) (B) states, "There shall be a minimum of two rotors per ditch, each having the capability of supplying the required oxygenation capacity with one rotor out of service. " In order to consistently meet effluent permit requirements, the City of Wylie wastewater treatment plant requires both mechanical rotors to be functioning simultaneously. (b) Final Clarifier The Texas Administrative Code Chapter 317 . 4 (d) (5) states, "The following design criteria for clarifiers are considered acceptable: Final : Activated sludge - maximum surface loading at design flow (gal/sq . /ft. /day) = 300" . The City of Wylie wastewater treatment plant final clarifier surface loading at design flow = 786 .6 gal/sq. /ft. /day. (c) Drying Bed Capacity The Texas Administrative Code 317 .12 Appendix D, "Required area (sq.ft. /capita) for sludge drying beds with aerobic sludges - Collin County = 1 .5 sq. ft. . The 1984 population estimate for the City of Wylie = 1, 400 ("Current Population 1984 Estimates" , North Central Texas Council of Governments, May 1984) . The square foot per capita sludge drying bed capacity at the City of Wylie wastewater treatment plant = 0 . 5 sq. ft. /capita. Since the August 19, 1985 District 4 letter, the only known alterations made at the wastewater treatment plant is that a tap was installed on the sludge return line in order to remove additional solids from the system and dispose of solids at an off-site area. G. Semiannual Progress Reports Item 8, under "Other Requirements" states, "Every six months commencing January 1980, the permittee shall submit to the department a report describing progress towards attainment of the following monthly average effluent limitations : Biochemical Oxygen Demand 10 mg/1 Total Suspended Solids 15 mg/1 The last such semiannual report received was January 24 , 1984 . City of Wylie Permit No. WQ0010384-001 May 14 , 1986 Page 7 Please notify this office within forty-five (45) days of receipt of this letter, in writing, of the steps taken to correct Items A through G in accordance with items and provisions of the Texas Administrative Code Chapter 317 and Texas Water Commission Permit No. WQ0010384-001 .

Windham, City of Wylie Director of Public Works, conducted an inspec- tion of a temporary lift station located on Douglas Street in the Oaks Develop- ment. During the inspection, the following was noted: 1. An unauthorized discharge of raw wastewater was occurring due to the lift station submersible pump being clogged. 2. There exists only one (1) submersible pump at the lift station. 3. There was no gate valve on the lift station discharge line. In accordance with the "Design Criteria for Sewage Systems", Texas Department of Water Resources Rules 156.17.02.001-.013, effective May 28, 1981, state: .002(d)(e)(E) - "Whenever any pumping unit handles waste from two or more residential housing units or from any public establishment, dual grinder pump units shall be provided to assure continued service in the event of equipment malfunction." .003(d)(2) - "Valves: Full closing valves shall be installed on the discharge piping to each pump and on the suction of all dry pit pumps. A swing check valve with external lever shall be installed on the discharge of each pump.
