Discharge to an unnamed tributary adjacent to the plant site; thence to Muddy Creek; thence to Lake Ray Hubbard in Segment No. 0820 of the Trinity river Basin. Uses deemed desirable: contact recreation, public water supply and high quality aquatic habitat. Plant located south of State Highway 78 and west of Birmingham Street, in the southwestern section of Wylie in Collin County, Texas. Parameters: 20 BOD5, 20 TSS, Added 3 D.O. Special Other Requirements: New Plant to be in operation by February 1, 1989 and existing plant phased out and shutdown by August 1, 1989. New plant to meet "advanced treatment" levels of 10 BOD5, 15 TSS, 3 NH3-N & 4 D.O. and have minimum capacity of 2.5 MGD. Permit Term: Expires December 1, 1989 dwara C. Jueng TECHNICAL SUMMARY City of Wylie Renewal of Permit No. 10384-01 April 9, 1987 The City of Wylie has requested renewal of their existing permit for the discharge of 800,000 gpd of treated domestic wastewater with effluent limitations of 20 mg/1 BODE and 20 mg/1 TSS. This permit renewal is for a limited time and includes provisions for the installation of new wastewater treatment facilities and subsequently shutting down the existing treatment facilities permitted for 800,000 gpd. The new facilities are to be designed for a capacity of at least 2,500,000 gpd and shall also be designed to meet "advanced treatment" levels delineated in effluent set 2-N of Chapter 309 of the TAC. These requirements and an implementation schedule is delineated in paragraph no. 3 of the "Other Requirements" section of the draft permit. The new facilities are to be in operation By February 1, 1989 and the existing 800,000 gpd facilities are to be shutdown by August 1, 1989. The new treatment plant is to be located at a landfill site across the road from the existing site. A closure plan for the landfill site was submitted to the Texas Department of Health (TDH) on April 1, 1987. This plan reflects that construction for closure of the site is to be complete by June 29, 1987, which is about 6 months prior to the initiation of construction for the new wastewater treatment plant. The existing facilities discharge treated effluent to an unnamed tributary adjacent to the plant site; thence to Muddy Creek; thence to Lake Ray Hubbard in Segment No. 0820 of the Trinity River Basin. The designated uses of this segment are contact recreation, high quality aquatic habitat and public water supply and is classified as a water quality limited stream. The latest Waste Load Evaluation (WLE) was approved on 5/21/74. The existing treatment facilities consist of an oxidation ditch, a clarifier, a chlorine contact basin, a sludge digester/holding basin and sludge drying beds. Final disposal of the sludge is in the Maxwell Creek Sanitary Landfill of the North Texas Municipal Water District. No change is recommended in the basic effluent discharge limitations of 20 mg/1 BODE and TSS for this proposed permit renewal . However, a minimum of 3 mg/1 disgolved oxygen (D.O.) has been specified for the effluent to aid in maintaining the goal of 3 mg/1 D.O. in non-segmented streams per the Texas Surface Water Quality Standards. The WLE reflects that the City of Wylie's discharge is 5.0 miles from Lake Ray Hubbard (Segment No. 0820) thus requiring a BODEof 10 mg/1. However, the actual discharge is approximately seven (7) miles, colsequently, a BOD5 of 20 mg/1 for the permit renewal should be satisfactory. The effluent limitations of 10 mg/1 BODE, 15 mg/1 TSS, 3 mg/1 NH -N and a minimum of 4 mg/1 D.O. are required for the hew 2.5 MGD (minimum) plant to meet the requirements of the Texas Surface Water Quality Standards for Muddy Creek and Segment 0820. The treated effluent for the existing facilities and the new plant shall contain a chlorine residual of at least 1.0 mg/1 after a detention time of at least 20 minutes, based on peak flow. Technical Summary Page 2 City of Wylie The proposed effluent limitations for both the existing and new facilities are consistent with the requirements of Chapter 309 of the TAC. The existing facilities are located south of State Highway 78 and west of Birmingham Street, in the southwestern section of Wylie in Collin County, Texas. The proposed permit renewal stipulates that the permit shall expire at midnight on December 1 , 1989. This will allow a contingency of four (4) months past the projected shutdown of the existing facilities by August 1, 1989. Once the draft permit is completed, it is sent to the notice section of the Texas Water Commission where a notice is written that is to be published by the applicant in a newspaper generally circulated in the county where the wastewater treatment plant will be located. A thirty day period is set aside once the notice is published for public comment. A notice is also sent out to the landowners identified in the permit application and any interested parties. At this time, if any comments requesting a public hearing are filed with the Commission, a public hearing is held. After the public hearing or after the thirty day waiting period is up with no request for a public hearing, the proposal for decision or draft permit is put before the Commissioners for a decision.

Additional definitions of words or phrases used in this permit are as follows: 1. Flow Measurements a. Daily average flow - the arithmetic average of all determinations of the daily discharge within a period of one calendar month or 30 consecutive days. The daily average flow determination shall consist of at least four separate determinations. If instantaneous measurements are used to determine the daily discharge, the determination shall be the average of all instantaneous measurements taken during a 24-hour period or during the period of daily discharge if less than 24 hours. b. Instantaneous flow - the measured flow during the minimum time required to operate the flow measuring device. c. 2-hour peak - the maximum flow sustained for a two hour period during the period of daily discharge. Multiple measurements of instantaneous maximum flow within a two-hour period may be compared to the permitted 2-hour peak flow. 2. Concentration Measurements a. Daily average concentration - the arithmetic average weighted by flow value of all samples, of all types, within a period of one calendar month or 30 consecutive days, consisting of at least four separate representative measurements. When four samples are not available in a 30 day period, the arithmetic average (weighted by flow) of all values in a four consecutive month period consisting of at least four measurements may be compared to the daily average limit. b. 7-day average ' concentration - the arithmetic average of all samples, of all types, within a period of seven consecutive days, consisting of at least three separate measurements. c. Daily maximum concentration - the maximum allowed concentration measured on a single day (by composite sample, unless otherwise specified). 3. Sample Type a. Composite sample - a sample made up of a minimum of three effluent portions collected in a calendar day or during the period of daily discharge if less than 24 hours, and combined in volumes proportional to flow; . or a sample continuously collected, proportional to flow, in a calendar day or during the period of daily discharge if less than 24 hours. Page 3 TMC 4/86 b. Grab sample - an individual sample collected in less than 15 minutes. 4. Permitted Facility - Wastewater facilities used in the conveyance, storage, treatment, recycling, reclamation and/or disposal of municipal sewage or industrial wastes, including sludge handling or disposal facilities under the jurisdiction of the Commission. 5. The term "sewage sludge" shall mean the solids and precipitates separated from wastewater by unit processes. MONITORING AND REPORTING 1.
