TECHNICAL MEMORANDUM ENVIRONMENTAL ENGINEERS AND SCIENTISTS Cibolo Creek Municipal Authority Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows Project No.: 0933 - 008 -01 Date: Revised December 19, 2017 Prepared For: Clint Ellis, General Manager, Cibolo Creek Municipal Authori ty% P�t �F TIq_511� Prepared By: Robert F. Adams, DE, PE j * ••' *�� Hannah Frels, EIT ............................ / ROBERT F. ADAMS r /Z/ 141� ��r, �; 65684 PURPOSE The purpose of this Technical Memorandum is to address the current flow through the Woman Hollering Treatment Plant, provide an evaluation of the flows relative to regulatory limits, and present an evaluation of two alternatives for increasing the capacity of the plant to handle further flow increases. The alternatives for handling additional flow include: 1.) adding a parallel package unit similar to the existing unit, or 2.) implementing a pump and haul operation to maintain the flow at approximately the 75% level. The 75% level was selected to provide some buffer in the remaining capacity in the plant to enable the facility to handle wet weather or other events that may create significant short term flow increases. The evaluation also considers the timeline for the construction of the new South Regional Water Reclamation Plant off of Trainer Hale Road. BACKGROUND The City of Schertz owns and Cibolo Creek Municipal Authority (CCMA) operates a small package wastewater treatment plant in Schertz, Texas. The plant was originally designed to treat wastewater collected from the expanding Sedona development. It is now formally known as the Woman Hollering Treatment Plant (Plant) and operates under the Texas Pollutant Discharge Elimination System Permit No. WO0015371001, which is held jointly by the City of Schertz and CCMA. The Plant is currently operated as an extended aeration, activated sludge system under the Interim Phase of the permit referenced above. See Figure 1 for current footprint and service area.

According to the TCEQ guidance, when the 30 -day running average of the Plant influent flow reaches 75% of the permitted flow for three consecutive months they must begin evaluating the current operating system for future capacity needs. According to historical discharge data, the flow is beginning to approach 75% of the permitted treatment capacity and thus an investigation is necessary in order to determine ways in which the future flows may 2of10 c: \users \radams\ documents \ccma\vvhtp\20171218_woman hollering alternatives.docx TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows be treated as they continue to increase. CCMA retained the services of Alan Plummer Associates, Inc. (APAI) in order to evaluate the available data and alternatives for handling increased flow in accordance with the permit, such that the Plant may avoid any possible permit violations. TPDES PERMIT Currently, the Plant is operating under the Interim Phase of the permit which was issued by the Texas Commission on Environmental Quality (TCEQ) on October 13, 2015. The permit is included as Attachment A to this report. Table 1 shows the discharge limitations under this phase. Table 1: Woman Hollering Plant Discharge Limitations Effluent Characteristic Daily Average Flow; mgd 0.046 Biological Oxygen Demand; mg /L 10 Total Suspended Solids; mg /L 15 Ammonia; mg /L 2 E. soli; CFU 126 Dissolved Oxygen; mg /L 6.0 The permit also includes provisions for a "Future" phase in which the Plant is authorized to discharge effluent volumes up to 0.096 million gallons per day (mgd), twice the current permitted discharge rate. In accordance with the section "Operational Requirements ", item number 8. a. of the TPDES permit, the permittee shall initiate engineering and financial planning for a capacity expansion whenever flow measurement at the existing facility reaches 75% of the permitted daily average flow for three consecutive months. And whenever flow measurements at the existing facility reach 90% of the permitted daily average flow for three consecutive months, the permittee shall obtain authorization from the TCEQ to commence construction of an expansion. Since the current permit already authorizes a capacity expansion, the path forward for Schertz and CCMA is to plan (design and financial) for additional capacity, since the increased discharge is already authorized. WASTEWATER QUANTITY DATA Discharge flow data has been collected since the Plant began operation. This historical data was evaluated for trends and future increases. The daily data collected from January 2013 through November 3of10 C WSersl racaa vA14\20171218_wc ran holIaring alierr?&U w�S.docx TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows 2017, is shown graphically in Figure 2. Figure 2 generally reflects the impact of storm events that have occurred in the area over the operating history. The shift from extreme drought conditions in 2013 and 2014 to excess rainfall conditions starting in mid -2015 increased the inflow arriving at the plant, with inflows continuing to increase dramatically during late 2015 and early 2016. The rate of increasing inflow volume seemed to be greater than the rate of new homes contributing flow. In early January 2017 a significant source of inflow was identified and eliminated. This inflow reduction resulted in an immediate decline in the 30 -day average flows, returning the flows to levels below 75 percent of the plant capacity. Since then, flows have continued to increase in response to development. 0.050 0.040 0 C7 ? 0.030 3 0 LL C O € 0.020 0.010 50.00 45.00 40.00 35.00 30.00 C 25.004 c To K 20.00 15.00 10.00 5.00 0.000 '– _ ■yam_. _ .su-E-111 —IL■ -M LL,_,_ ■�_u i__ l �. _ - 0.00 r T O O O O N N N N r 0 O O 0 O N N N T r r r O O O O O N N N N N r r r O O O O O O O O O O N N N N N N N N N N Figure 2: Historical Influent Flow to Woman Hollering Plant More recent influent trends at the Plant are highlighted in Figure 3. Although some of the peak inflow periods shown in the Figure 2 were impacted by heavy rainfall -- April -June, 2015; October 2015; and March -May, 2016 -- there is a trend of generally increasing influent flow.

In January 2017 several significant inflow sources were identified at wastewater lateral connections to manholes. When the inflow points were corrected to eliminate groundwater intrusion into the system the flow dropped from about 0.06 mgd to about 0.03 mgd . This resulted in reducing the flow below 75% of the capacity for the current unit as authorized by the permit. Figure 3 shows the recent monthly average flow trend, reflecting the continued increase in flow as additional housing units are added to the system. While the flows were less than 75% of the plant capacity through the summer of 2017, the 30 -day average flow recently surpassed this level again in November. 0.05 0.046 MOD Monthly Avg — Permitted Flow 0.04 75% of Permitted Flow 0.0345 MOD 0.036 - – - Nov. 0.033 0.03 _ 0.032 _ Oct. - -. — Sept. 0.027 0.028 c July Aug. m c 0.02 - - _ -- 0.01 0 - -- Month - 2017 Figure 3: 2017 Flows at Woman Hollering Treatment Plant 5of10 c:\ users \radams\ documents \ccma \whtp\20171218_woman hollering alternatives.docx TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows The average monthly increase in flow was evaluated by dropping the monthly average flows for the period June 2016 through February 2017. This resulted in an average month over month flow increase of 2.48 %.

TREATMENT ALTERNATIVES There are two potential options for increasing the flow being treated at the existing plant in a short time frame. The first option discussed in depth is presented as Alternative No.1 and suggests that CCMA and 6of10 c:\ users \radams\ documents \ccma \whtp\20171218_woman hollering alternatives, d ocx TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows Schertz lease another package plant with capacity to treat 0.046 mgd of wastewater flow. The second option, presented as Alternative No. 2, proposes that the City of Schertz acquire the services of a licensed hauler to transport wastewater flows from the Plant to another wastewater treatment plant for treatment and discharge. This section of the report explores both alternatives and includes costs and startup times for each. ALTERNATIVE 1 — Parallel Package Plant at Existing Site The existing package plant is rated at 0.046 mgd and was designed and installed by AUC Group in 2010. The Plant consists of a manual bar screen, aeration basin, final clarifier, chlorine contact basin, and sludge digestion basin. The final effluent is conveyed to Woman Hollering Creek for discharge and digested sludge is hauled to CCMA Odo J. Riedel Water Reclamation Facility (CCMA OJR) for treatment, dewatering, and final disposal. A twin package plant could be rented from the same manufacturer and influent flow could split to each bar screen for treatment by either the existing package plant or the new package plant, as shown on the site in Figure 5. 7of10 c_Auss'IS;radc_n"S'_';ccumc ,,,cc na\, vrtrl'O_11_. ,18 t i_,[ing al'ga na u' doay TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows Figure 5: Proposed Package Plant Location 2 Year Costs, Construction and O &M = $612,500 See Attachment B for cost estimate for Alternative No. 1. Startup time = 60 -90 Days ALTERNATIVE 2 — Haul Wastewater from Existing Site to Another Treatment Plant In order to reduce the flow being treated at the existing plant, the City of Schertz could employ the services of a registered hauler to load and transport 5,500 gallons of wastewater from the aeration basin at Woman Hollering Treatment Plant to another TCEQ permitted wastewater treatment plant as shown schematically in Figure 6. Consideration was given to loading the truck from the FM -1518 lift station, but for the loading of 1 to 2 loads per day in the early stages of operation, the truck would need to sit at the lift station for extended periods of time (4 - 6 hours, depending upon time of day) waiting for the truck to load. 8of10 c:\ users \radams\ documents \cana \vvhtp\20171218_wom2n hollering alternatives.docx TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows This would result in extra costs for the truck and driver while loading. The truck can proceed to the existing plant and load from the aeration basin, filling the tank in a short period of time (30 minutes), avoiding the additional charges for waiting /filling time. CCMA OJR is located within relatively close proximity to the Plant, a five mile drive directly north. CCMA has capacity to accept the screened wastewater at the front of the plant. The hauling truck would pump the Woman Hollering wastewater from the aeration basin into the tank of the truck. It would then transport the volume to CCMA OJR where it would pump the screened wastewater into the headworks splitter box. The flow would then be treated by the existing CCMA OJR activated sludge system and discharged to Cibolo Creek in accordance with TPDES Permit No. WQ0011269001. Costs associated with Alternative No. 2 include site improvements at the Woman Hollering Treatment Plant in order to allow for uninterruptible access to the facility via Class 8 tractor and trailer.

Startup time = 30 days RECOMMENDATIONS After careful evaluation of both alternatives and coordination with a service supplier for wastewater hauling and wastewater treatment plant manufacturers, the recommended alternative for handling increased wastewater to flow to Woman Hollering Treatment Plant is the installation of an additional package plant. The existing raw sewage influent line will connect to a new junction box so that flow may be split between the two package plants. Effluent flow will collect at another junction box between the package plants and 9of10 c.lus�ru�ra ai��s a�curr�n���cnr,., ���201 /121 vioman hollerhrlg niter -.tiv, s.d -,az TECHNICAL MEMORANDUM Woman Hollering Treatment Plant Evaluation of Alternatives to Treat Increasing Flows the effluent outfall so that the flow may be combined before conveyance to Woman's Hollow Creek for discharge. The familiarity of the operation of the package plant and affordable two year cost, make this alternative an attractive option for Schertz and CCMA. Although the start -up time is longer than the hauling alternative, the Plant is not projected to exceed 90% of the effluent flow limit until the spring of 2017. This allows sufficient time to install the new parallel package plant if action is taken soon. Implementation of the pump and haul option would require ongoing coordination and scheduling between CCMA and the hauler, with some uncertainty regarding scheduling. There are times at night or weekends may scheduling the hauling operation could present a challenge, particularly during storm events when inflows may be increasing rapidly. Implementation of either option will require notification of TCEQ and coordination related to the existing permit; however, since the Future Phase is already included in the existing permit the addition of capacity with a parallel unit is straightforward. 10 of 10 \user-`A- aC+a-nvyaocL!m-3 _s\ccma\ v _-V201 1 )18v,ofnan E o l .r,r_ ah_ n.a. e_.dctcx ATTACHMENT A CIBOLO CREEK MUNICIPAL AUTHORITY TCEQ TPDES PERMIT NO.

As required by Title 3o Texas Administrative Code (TAC) Chapter 305, certain regulations appear as standard conditions in waste discharge permits. 3o TAC § 305.121- 305.129 (relating to Permit Characteristics and Conditions) as promulgated under the Texas Water Code (TWC) §§ 5.103 and 5.1o5, and the Texas Health and Safety Code (THSC) §§ 361.017 and 361.024(a), establish the characteristics and standards for waste discharge permits, including sewage sludge, and those sections of 40 Code of Federal Regulations (CFR) Part 122 adopted by reference by the Commission. The following text includes these conditions and incorporates them into this permit. All definitions in TWC § 26.001 and 3o TAC Chapter 305 shall apply to this permit and are incorporated by reference. Some specific definitions of words or phrases used in this permit are as follows: 1. Flow Measurements a. Annual average flow - the arithmetic average of all daily flow determinations taken within the preceding 12 consecutive calendar months. The annual average flow determination shall consist of daily flow volume determinations made by a totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with one million gallons per day or greater permitted flow. b. Daily average flow - the arithmetic average of all determinations of the daily flow within a period of one calendar month. The daily average flow determination shall consist of determinations made on at least four separate days. If instantaneous measurements are used to determine the daily flow, the determination shall be the arithmetic average of all instantaneous measurements taken during that month. Daily average flow determination for intermittent discharges shall consist of a minimum of three flow determinations on days of discharge.. c. Daily maximum flow -- the highest total flow for any 24 -hour period in a calendar month. d. Instantaneous flow - the measured flow during the minimum time required to interpret the flow measuring device. e. 2 -hour peak flow (domestic wastewater treatment plants) - the maximum flow sustained for a two -hour period during the period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two -hour period may be used to calculate the 2 -hour peak flow. f. Maximum 2 -hour peals flow (domestic wastewater treatment plants) - the highest 2 -hour peak flow for any 24 -hour period in a calendar month. 2. Concentration Measurements a. Daily average concentration - the arithmetic average of all effluent samples, composite or grab as required by this permit, within a period of one calendar month, consisting of at least four separate representative measurements. i. For domestic wastewater treatment plants - When four samples are not available in a calendar month, the arithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting of at least four measurements shall be utilized as the daily average concentration. Page 3 City of Schertz and Cibolo Creels Municipal Authority TPDES Permit No. WQ0015371001 ii. For all other wastewater treatment plants - When four samples are not available in a calendar month, the arithmetic average (weighted by flow) of all values taken during the month shall be utilized as the daily average concentration. b. 7 -day average concentration - the arithmetic average of all effluent samples, composite or grab as required by this permit, within a period of one calendar week, Sunday through Saturday. e. Daily maximum concentration - the maximum concentration measured on a single day, by the sample type specified in the permit, within a period of one calendar month. d. Daily discharge - the discharge of a pollutant measured during a calendar day or any 24- hour period that reasonably represents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants with limitations expressed in other units of measurement, the daily discharge is calculated as the average measurement of the pollutant over the sampling day. The daily discharge determination of concentration made using a composite sample shall be the concentration of the composite sample. When grab samples are used, the daily discharge determination of concentration shall be the arithmetic average (weighted by flow value) of all samples collected during that day. e. Bacteria concentration (E. soli or Enterococci) - Colony Forming Units (CFU) or Most Probable Number (MPN) of bacteria per loo milliliters effluent. The daily average bacteria concentration is a geometric mean of the values for the effluent samples collected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product of all measurements made in a calendar month, where n equals the number of measurements made; or, computed as the antilogarithm of the arithmetic mean of the logarithms of all measurements made in a calendar month, For any measurement of bacteria equaling zero, a substituted value of one shall be made for input into either computation method. If specified, the 7 -day average for bacteria is the geometric mean of the values for all effluent samples collected during a calendar week, f. Daily average loading (lbs /day) - the arithmetic average of all daily discharge loading calculations during a period of one calendar month. These calculations must be made for each day of the month that a parameter is analyzed. The daily discharge, in terms of mass (lbs /day), is calculated as (Flow, MGD x Concentration, mg /l x 8.34). g. Daily maximum loading (lbs /day) - the highest daily discharge, in terms of mass (lbs /day), within a period of one calendar month. 3. Sample Type a. Composite sample - For domestic wastewater, a composite sample is a sample made up of a minimum of three effluent portions collected in a continuous 24 -hour period or during the period of daily discharge if less than 24 hours, and combined in volumes proportional to flow, and collected at the intervals required by 3 o TAC § 319.9 (a). For industrial wastewater, a composite sample is a sample made up of a minimum of three effluent portions collected in a continuous 24 -hour period or during the period of daily discharge if less than 24 hours, and combined in volumes proportional to flow, and collected at the intervals required by 3o TAC § 319.9 (b). Page 4 City of Schertz and Cibolo Creek Municipal Authority TPDES Permit No. WQ0015371001 b. Grab sample - an individual sample collected in less than 15 minutes. 4. Treatment Facility (facility) - wastewater facilities used in the conveyance, storage, treatment, recycling, reclamation and /or disposal of domestic sewage, industrial wastes, agricultural wastes, recreational wastes, or other wastes including sludge handling or disposal facilities under the jurisdiction of the Commission. 5. The term "sewage sludge" is defined as solid, semi - solid, or liquid residue generated during the treatment of domestic sewage in 3o TAC Chapter 312. This includes the solids that have not been classified as hazardous waste separated from wastewater by unit processes. 6. Bypass - the intentional diversion of a waste stream from any portion of a treatment facility. 1. Self-Reporting Monitoring results shall be provided at the intervals specified in the permit. Unless otherwise specified in this permit or otherwise ordered by the Commission, the permittee shall conduct effluent sampling and reporting in accordance with 3o TAC §§ 319.4 - 319.12. Unless otherwise specified, a monthly effluent report shall be submitted each month, to the Enforcement Division (MC 224), by the 20th day of the following month for each discharge which is described by this permit whether or not a discharge is made for that month. Monitoring results must be reported on an approved self-report form that is signed and certified as required by Monitoring and Reporting Requirements No. 1o. As provided by state law, the permittee is subject to administrative, civil and criminal penalties, as applicable, for negligently or knowingly violating the Clean Water Act (CWA); TWC §§ 26, 27, and 28; and THSC § 361, including but not limited to knowingly making any false statement, representation, or certification on any report, record, or other document submitted or required to be maintained under this permit, including monitoring reports or reports of compliance or noncompliance, or falsifying, tampering with or knowingly rendering inaccurate any monitoring device or method required by this permit or violating any other requirement imposed by state or federal regulations. 2.
