BOROUGH OF SEWICKLEY WASTEWATER TREATMENT PLANT MUNICIPAL WASTELOAD MANAGEMENT REPORT

OPERATING YEAR 2020 PURPOSE AND SCOPE

This report is submitted to satisfy the requirements of Chapter 94 - Municipal Wasteload Management, of the Pennsylvania Department of Environmental Protection (PaDEP) Rules and Regulations for the National Pollutant Discharge Elimination System (NPDES) Permit No. PA0020681. This report presents the following:

1. Hydraulic loading graph. 2. Organic loading graph. 3. A discussion of the hydraulic and organic loadings and projections

methodology. 4. A description of all sewer extensions approved and all sewer extensions

constructed in the year reported. 5. A description of the operation and maintenance program for the sewer

system including monitoring. 6. A discussion of the condition of the sewer system. 7. A discussion of the condition and capacity of the sewage lift stations

within the collection system. 8. A description of industrial waste dischargers. 9. Solids Management. 10. Annual Combined Sewer Overflow Status Report

SECTION 1: HYDRAULIC LOADING GRAPH (§ 94.12.(a)(1)) Figure 1 contained in Appendix B presents the hydraulic loading graph illustrating flows as recorded at the Sewickley Borough Wastewater Treatment Plant (WWTP) for the period of time between 2016 and 2020. Figure 1 also presents flow projections for the coming five-year period (2021 through 2025). The actual data is presented in tabular form appended as Table 1. Section 3 of this report provides discussion of the past and


projected future hydraulic loadings. Also shown on Figure 1 is the permitted hydraulic capacity (0.900 mgd). SECTION 2: ORGANIC LOADING GRAPH (§ 94.12.(a)(2)) Figure 2 contained in Appendix B presents the organic loadings tributary to the Sewickley WWTP for the most recent five-year period (2016 through 2020) and projects organic loadings for the coming five-year period (2021 through 2025). Historic loading data is provided in tabular form appended as Table 2. Section 3 of this report discusses past and projected future organic loadings. Figure 2 also presents the design influent BOD5 loading (1,800 lbs/day). SECTION 3: DISCUSSION OF HISTORIC HYDRAULIC AND ORGANIC

LOADINGS AND PROJECTIONS (§ 94.12.(a)(3))

Historic Hydraulic Loadings The annual average flow to the WWTP during 2020 was 0.779 mgd as shown on Table 1 and Figure 1. The five-year average of the annual average flow (2016 through 2020 period of record) is 0.785 mgd. The 90-day sustained flow recorded at the WWTP computed is 0.991 mgd in 2020 and the five-year average of the annual 90-day sustained flow rate computed is 0.915 mgd. During the most recent five-year period of record, the 90-day sustained recorded flow rates exceeded the design flow capacity (0.9 mgd) in 2018 and 2020. It is noted that the annual average and 90-day sustained flows identified above are per the Average Monthly flow values reported on the Borough’s Discharge Monitoring Reports. An existing overflow at the treatment plant was active 5 times in 2020 with a total discharge volume of 0.520 MG. A summary of the discharges at the Treatment Plant are included in Table 10 in Appendix B. As required by Chapter 94 regulations, the calibration certificate for the treatment plant flow meters are provided in Appendix A. Projected Future Hydraulic Loadings - Annual Average Basis The base datum for hydraulic loading projections is the four-year annual average flow from 2016 to 2017 and 2019 to 2020 of 0.757 mgd. The year 2018 was not used to compute the projects because abnormally high precipitation levels observed in 2018 are not considered typical. Projections of yearly increases are based on an additional 20 EDUs per year estimated from future projections reported from Glen Osbourne Borough, Aleppo Township, plus the Borough of Sewickley, assuming 400 gpd/EDU. As shown on Figure 1 and Table 3, Appendix B, the projected 90-day sustained flow is not expected to exceed the hydraulic design capacity in the years 2021 and 2022. However, a


hydraulic overload is projected beginning in 2023. The 5-year 90-day sustained to annual average ratio was used to project the maximum flow rates. Table 3, Appendix B, presents a summary of the projected hydraulic load. Historic Organic Loadings The annual average loading to the treatment plant in 2020 was computed to be 457 lbs BOD5/day. The 2020 maximum month loading (February) was found to be 928 lbs BOD5/day. The maximum month organic loading was below the capacity of 1,800 lbs BOD5/day. Therefore, based on reporting criteria as defined by Title 25, Chapter 94.1 of the Pennsylvania Code, the WWTP was not organically overloaded in 2020. Projected Future Organic Loadings Projected future organic loadings were computed similarly to the projected hydraulic loadings from a “base datum”. The base datum for the organic loading projections is the historic loading of 608 lbs BOD5 per day (five year annual average from 2016 to 2020). Projections of yearly increases are based upon an additional 20 EDUs per year, estimated from proposed growth of Glen Osbourne Borough, Aleppo Township, plus Sewickley Borough. Per PaDEP regulations, 0.17 lbs BOD5 per day per person was utilized. Table 3 presents a summary of the projected organic load. Maximum monthly loads were projected based upon a historic ratio of maximum month to annual average of 1.59 derived as shown on Table 2. As shown on Figure 1 and Table 2, Appendix B the maximum monthly loading is not projected to exceed the design BOD5 Load (1,800 lbs/day) in the coming 5-year period. SECTION 4: SEWER EXTENSIONS (§ 94.12.(a)(4)) No sewer extensions were completed within the Borough of Sewickley or Glen Osbourne. The Township of Aleppo began construction of 357 linear feet of sanitary sewer lines and manholes for twelve residential structures for the Ferndale Plan of Lots in 2018. This construction was finished in 2019. New connections within the system are as follows:

1. Four of the twelve connections in Aleppo have been constructed in the

Ferndale Plan Lots.

2. All ten of the planned connections for the Masonic Village at Sewickley plan have been constructed.

3. Glenn Osborne did not report any new development or connections.

4. The Borough of Sewickley did not have any residential taps to the sewer

system in 2020.


Refer to Aleppo report contained in Appendix C and the Glenn Osborne report contained in Appendix D regarding extensions upstream of the Sewickley collection system. As presented in Section 3, an average of 20 connections are planned each year for the next five years (total - approximately 100 EDUs). SECTION 5: SEWER SYSTEM MONITORING, MAINTENANCE, REPAIR

AND REHABILITATION (§ 94.12.(a)(5)) The Borough of Sewickley Waste Water Treatment Plant receives sewage from the Borough of Sewickley, Aleppo Township and Glen Osborne Borough. Sewage flow is metered and recorded at the wastewater treatment plant, at the Chestnut Street Lift Station, Boundary Street Lift Station, and Seibert Lift Station. Sewickley Borough is responsible for operating the collection system within the Borough of Sewickley, which includes sanitary sewers, three lift stations, and the sewage treatment plant. The Borough of Sewickley is also responsible for operation of the Seibert Lift Station located in Glen Osborne. These responsibilities include the administration, operation, maintenance, and monitoring of the plant and lift stations. The Borough of Glen Osborne and Aleppo Township are responsible for operating the portions of the collection system located within their municipal boundaries. Required monitoring parameters per the NPDES Permit are presented in the following table.

An NPDES Permit Renewal was filed for Borough of Sewickley WWTP in August 2015. The permit is currently under review. Sewer maintenance and repair was performed by Borough of Sewickley on an as needed basis. Borough of Sewickley WWTP maintains a staff including the WWTP Superintendent and employees to perform maintenance and operate the sewers and pumping stations. Inspections are made at the trouble spots in the system and corrective action is taken as necessary. The Borough also conducts inspections and system maintenance as complaints are received and takes steps to alleviate any issues found. The Borough performed routine cleaning and CCTV work during 2020. Minor sewer repairs were also made on Elizabeth Street and Grimes Street.


Per previous reporting, the following items have been submitted to PaDEP by the Borough:

1. System Inventory and Characterization Report (October 20, 1994); 2. System Hydraulic Characterization Report (May 1, 1995); 3. Documentation of Implementation of Nine Minimum Controls

(November 10, 1995); and 4. Long Term Control Plan (March 3, 2000 with letter revisions (dated

January 23, 2008). Refer to the appended report in Appendix C for a list of maintenance activities performed by Aleppo. Refer to the appended report in Appendix D for a list of maintenance activities performed by Glen Osborne. SECTION 6: CONDITION OF THE SEWER SYSTEM (§ 94.12.(a)(6)) The sanitary sewer collection system within the Borough of Sewickley was originally constructed during the late 1800s and early 1900s. The collection system is a combined system, however storm water inlets have been disconnected over the years from the sanitary and combined sewer system in conjunction with roadway improvement projects. Portions of the system have shown deterioration due to age, however the Borough remains proactive in terms of inspection, cleaning, and repair. A budget allowance is allotted annually for repairs. Currently the Borough of Sewickley is evaluating potential future abandonment of the existing Sewickley Wastewater Treatment Plant and connection of the sanitary sewer system to the Leetsdale Wastewater Treatment Plant Refer to Appendix C and Appendix D for information pertaining to the Aleppo and Glenn Osborne service areas. SECTION 7: LIFT STATIONS (§ 94.12.(a)(7)) In addition to the WWTP influent pumping system, the Borough of Sewickley owns and operates three (3) collection system lift stations within the Borough of Sewickley and one (1) lift station, the Seibert Street Pump Station, in Glen Osborne. The design capacities and a summary of the lift stations operating data is provided in Table 4. Refer to Appendix B Tables 5 through 8 for additional pumping station data.

SECTION 10: ANNUAL COMBINED SEWER OVERFLOW STATUS REPORT

BOROUGH OF SEWICKLEY Allegheny County, Pennsylvania

Annual Combined Sewer Overflow Status Report Operating Year 2020

1.0 Introduction

The purpose of this report is to meet the requirements of the Borough of Sewickley’s National Pollutant Discharge Elimination System (NPDES) Permit (Permit No. PA0020681) which requires that “on March 31 of each year, an annual CSO Status Report Shall be submitted to the Department with the annual Municipal Wasteload Management Report required by 25 PA Code Chapter 94, Section 94.12”. In September of 2018 the Borough of Sewickley began metering a fifth existing overflow located at the sewage treatment plant. The five constructed CSO structures/outfalls within the Borough of Sewickley system as listed below. All CSO outfall pipes have flow meters installed.

1. Outfall 002 - Boundary Street 2. Outfall 003 - Maple Lane 3. Outfall 004 - Chestnut Street 4. Outfall 005 - Academy Avenue 5. Treatment Plant

With the exception of Academy Avenue, the CSO Structures are located upstream of the associated pump stations. In 1998, the Borough removed the regulator mechanisms in the CSO chambers and raised the weir elevations to maximize storage in the collection system. 2.0 Summary of CSO Discharges for 2020 A summary of CSO discharges from operating year 2020 is included in Appendix B of this report. Appendix B, Table 10 provides a summary of discharges from each CSO by month and Table 11 provides additional detail for each discharge including cause, frequency, duration and quantity of flow, and rainfall information. The tables summarize data reported in the monthly discharge monitoring report (DMR) using the PaDEP DMR forms for CSOs. 3.0 Water Quality Impacts Untreated domestic, commercial and industrial wastes and runoff from CSOs contain various contaminants that may impact surface water quality.


4.0 Implementation of the Nine Minimum Controls Per previous reporting, the Borough previously submitted the following:

1. System Inventory and Characterization Report on October 20, 1994 2. System Hydraulic Characterization Report on May 1, 1995. 3. Documentation of implementation of Nine Minimum Controls on November

10, 1995.

Continued effort to implement the NMCs are demonstrated as follows:

1. Proper operation and regular maintenance programs for the sewer system and CSO outfalls.

Sewer maintenance and repair is performed by Borough of Sewickley on an as needed basis. Borough of Sewickley WWTP maintains a staff including the WWTP Superintendent and employees to perform maintenance and operate the sewers and pumping stations. Inspections are made at the trouble spots in the system and corrective action is taken as necessary. The Borough also conducts inspections and system maintenance as complaints are received and takes steps to alleviate any issues found.

2. Maximum use of the collection system for storage.

In 1998, the Borough removed the regulator mechanisms in the CSO chambers and raised the weir elevations to maximize storage in the collection system.

3. Review and modification of pretreatment requirements to assure CSO impacts

are minimized.

There are no industrial dischargers to the sewage system. The Borough enforces the installation of grease traps at restaurants to protect the system. Monitoring of the system is completed to identify any issues associated with grease accumulation.

4. Maximization of flow to the POTW for treatment.

Efforts are made to maximize flow to the treatment plant. To control river influence on the treatment plant, a manhole was constructed with stop log weirs to allow plant operators to control the backflow during high river stages and/or flood conditions. Storm water inlets have been disconnected over the years from the sanitary and combined sewer system in conjunction with roadway improvement


projects. A comprehensive plan has been developed to separate much of the storm water from the sanitary/combined sewers.

5. Elimination of CSOs during dry weather

No dry weather discharges occurred during the 2020 operating year.

6. Control of solid and floatable materials in CSOs

The Public Works Department completes street sweeping throughout the Borough which helps to control solids and floatables making their way to the CSOs.

7. Pollution prevention programs to reduce contaminants in CSOs.

The Borough engages outside contractors for sewer system cleaning. Further, the Borough promotes public educational efforts through their website and Sewickley TV to inform residents of the importance of pollution prevention.

8. Public notification to ensure that the public receives adequate notification of CSO occurrences and CSO impacts

Public education initiatives are included on the Borough's website including informational videos, instructions for placing leaves for collection and sewage treatment plant videos. Additionally, the Borough places placards on the curbs above the catch basins annually with the road program.

9. Monitoring to effectively characterize CSO impacts and the efficacy of CSO

controls

Flow meters are installed at each CSO discharge pipe to monitor. Rainfall is also monitored using a rain gauge. Summaries of this data are included in Appendix B.
