EXHIBIT A-I Page 3 of 6 EXHIBIT A-1 ATTACHMENT A ALLISON WWTP NITRIFICATION PROCESS PRELIMINARY DESIGN FOR ALLISON WWTP PROCESS UPGRADE & REPLACEMENT Project No. E10045 Due to loadings to the Allison WWTP from a meat packing plant and resulting issues with plant operations and meeting TCEQ ammonia nitrogen limits a analysis will be performed to develop alternatives for a solution to this issue. With technical assistance from the sub-consultant of Freese and Nichols (FNI) the analysis will be developed to identify alternatives to improve nitrification compliance at the plant. The project deliverable will be a technical memorandum to the City with alternatives and proposed solution. PROJECT BACKGROUND A. The Allison Wastewater Treatment Plant(AWWTP)was designed in 1983 for an average daily design flow of 5 MGD with effluent parameters of BOD 20 mg/land TSS 20 mg/I. B. The current TCEQ discharge permit limits are BOD 20 mg/I, TSS 20 mg/land Ammonia Nitrogen (NH3-N) of 12 mg/I. AWWTP has two permitted effluent outfalls. The first is for the plant itself and has a current NH3-N limit of 12 mg/I and the second is the demonstration project across the river with a current limit of 3 mg/I. There have been periodic NH3-N permit excursions reported. The City no longer discharges to the second outfall because of the inability to comply with the NH3-N limit. C. A meat packing plant located in Corpus Christi, is a significant industrial wastewater discharger in the AWWTP basin. It is believed that this facility, which appears to have limited pretreatment, is a major contributor to the loading at the AWWTP and the NH3-N loading in particular. Flow/loading from the industry includes both meat processing wastes as well as chemicals for treating cowhides and for wash-down. All of this industry's waste discharge at a proximate lift station. The waste stream can be isolated and has daily composite testing results that should be available. STUDY ASSUMPTIONS: A. Future flows to be used for the AWWTP basin are as projected in the 2015 City of Corpus Christi Wastewater Planning Report by Stantec. B. The City has an approved Industrial Pretreatment Program which will reviewed for a possible basis for mitigating the organic and NH3-N loading to the AWWTP. C. NH3-N concentration limit has the possibility to be lowered from 12 mg/I to 3 mg/I at some point in the future. EXHIBIT A-I Page 4 of h • PROJECT SCOPE A. Workshop and Meetings: Urban Engineering (UE) shall coordinate meetings with the City staff and UE and FNI shall both attend. 1. Workshop with UE and City, to include AWWTP operations personnel, Wastewater Department leadership, and either separately or jointly with the meat processing facility representative and with City staff related to pretreatment alternatives. 2. Meet with City to review Draft Nitrification Technical Memorandum. 3. Meet with City to review Final Nitrification Technical Memorandum. B. Site Visits 1. Schedule and conduct two site visits, one each to the AWWTP and the meat processing facility. C. Analysis 1. Obtain and review past operations and testing data for the AWWTP and Clarkwood North Lift Station. City to provide data and FNI to analyze. 2. Develop up to four alternatives for meeting current and future loadings and permit limits. It is anticipated that the alternatives will comprise combinations of options which may include: a. Additional pretreatment at the industry b. No additional pretreatment at the industry c. Use of new basins to achieve nitrification d. Use of existing basins with added media or membranes to achieve nitrification 3. Alternative development may involve process computer modeling as deemed appropriate based on data review(a separate line item is provided and will only be invoiced if used). 4. Alternatives will be submitted to City for review and approval. 5. Develop conceptual design and budget level costs estimate of proposed solutions and provide in a draft Technical Memorandum. 6. Meet with City staff to review and discuss the draft Technical Memorandum. 7. Address comments and questions provided by the City staff and submit a final Technical Memorandum. EXHIBIT A-1 Page 5 of 6 EXHIBIT A-1 ATTACHMENT B ALLISON WWTP POLLUTANT SURCHARGE RATE ANALYSIS FOR ALLISON WWTP LIFT STATION AND PLANT IMPROVEMENTS Project No. E10043 Due to loadings to the Allison WWTP (AWWTP)from a meat packing plant and resulting issues with plant operations and meeting TCEQ ammonia nitrogen limits a pollutant surcharge rate analysis will be performed to develop new surcharge rates for conventional pollutants (BOD, TSS and TKN). Technical assistance will be provided from sub- consultant Freese and Nichols (FNI). The project deliverable will be a technical memorandum to the City on the surcharge rate analysis. PROJECT SCOPE A. Pollutant Surcharge Rate Analysis 1. Obtain and review historical data required for the development of surcharge rates such as Industrial Users (lUs) permits and monitoring reports; Operation and Maintenance (O&M) costs of the A WWTP for the last five years; available insurance assessed value of assets or cost information of the construction of the AWWTP, including improvements; number of employees associated with the AWWTP and collection operation; sewer rates, etc. City to provide data. 2. Develop new surcharge rate evaluation criteria and methodology. 3. Calculate new surcharge rates for the following conventional pollutants: Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), and Total Kjeldahl Nitrogen (TKN). TKN will be used instead of Ammonia-Nitrogen since it is a true measure of the actual Ammonia-Nitrogen in the influent to the plant. The new surcharge rates for the pollutants shall be representative of the actual cost of treatment incurred by the City at the AW WTP. 4. Determine a maximum allowable concentration for BOD, TSS, and TKN in discharges from lUs in order to protect the AWWTP from slug loads. Incorporate the maximum discharge concentration into the new surcharge rate calculation. 5. Prepare a technical memorandum on the surcharge rate analysis with the list of recommended parameters; a description of the surcharge evaluation criteria; surcharge rate methodology; development of new surcharge rates; and maximum allowable discharge concentration for the surcharge pollutants. 6. Address comments and questions provided by the City staff and submit a final Technical Memorandum. B. City Ordinance Update Assist with the update of"Chapter 55-Utilities, Article Xl. -Commercial and Industrial Waste Disposal and Pretreatment" of the City of Corpus Christi City Ordinance to incorporate the new surcharge rates and other changes related to its implementation.
