4.0 BACKGROUND

The City of St. Peters owns and operates the St. Peters Spencer Creek Sewage Treatment Plant authorized to discharge to the Spencer Creek under a Missouri State National Pollutant Discharge Elimination System Permit (NPDES), permit number MO-0030970. The plant has a design flow of

9.5 million gallons per day (MGD)with an average daily flow of 6 MGD. The plant treats wastewater from the City’s collection system to remove pollutants and protect water quality prior to discharge to the receiving stream. Sludge waste is mixed with wood fiber and composted into a Class A compost product.

The treatment plant is composed of the following - Influent lift station / first flush concrete basin / four (4) earthen basins used for flow equalization or sludge storage / mechanical screening / grit removal / two (2) oxidation ditches / three (3) clarifiers / UV disinfection / reaeration tank with effluent pump station / two (2) aerated sludge holding tanks / two (2) sludge belt presses / eight (8) static pile aerated compost bins.

The Treatment Plant receives wastewater from residential, commercial, and industrial sources throughout the City. A process flow diagram of the WWTP is shown in Figure 1. Wastewater enters through an influent lift station, with a concrete basin, with four extraneous flow basins available for flow equalization or sludge storage during wet-weather events. Flow then passes through mechanical screening and grit removal before entering two oxidation ditches, where extended aeration provides biological treatment and breaks down organic material and nutrients. Mixed liquor from the oxidation ditches flows to three secondary clarifiers, where solids settle out and are separated from the treated water. Clarified effluent is disinfected using ultraviolet light and passes through a reaeration basin before discharge through the facility's permitted outfall (Outfall #001).

Waste activated sludge is thickened in two aerobic sludge holding tanks via a decanting process, dewatered using belt filter presses, and the resulting cake is composted in aerated compost bins at the City's Earth Center.

The facility currently performs well in removing organic material and ammonia; however, the State of Missouri has established statewide nutrient reduction requirements that apply to this facility.

Under 10 CSR 20-7.015(9)(B)2, domestic point sources with a design flow of 1.0 MGD or greater must meet a total phosphorus target of 1.0 mg/L as an annual average, an equivalent mass-loading target, or a 75 percent influent-to-effluent reduction, no later than January 1, 2033. Total nitrogen (TN) is currently reserved under this rule, meaning the state has not yet established a statewide numeric TN target; however, the City intends to address TN treatment as part of this design to support long-term water quality goals for the receiving stream and position the facility ahead of anticipated future requirements.

The Spencer Creek Sewage Treatment Plant currently voluntarily participates in the Missouri Municipal Wastewater Nutrient Optimization Pilot program. Data resulting from process changes implemented under this pilot project will be shared with selected firm.

To support the evaluation and implementation of nutrient removal at the St. Peters Spencer Creek Sewage Treatment Plant, the City wishes to conduct a preliminary design effort to develop a treatment system capable of reliably reducing Total Phosphorous and Total Nitrogen concentrations in plant effluent to meet future regulatory limits. This effort will include evaluation of treatment alternatives and life cycle cost comparisons, conceptual design, and preparation of an engineering report with opinion of probable costs to integrate the recommended treatment system with the existing wastewater treatment processes

5.0 CITY OF ST. PETERS RESPONSIBILITIES

The CITY shall provide the following services to assist the ENGINEER:

1. Provide information as to the requirements of the project.

2. Assist the Engineer by providing existing CITY information, records, and reports pertinent to the project.
