18.  Analyses conducted for each facility to:  Cost effectively meet NPDES & Regulatory requirements  Meet possible future requirements  Part of plant upgrade & expansion designs  Includes alternatives analysis evaluating various requirements, effectiveness, and constraints Facility Upgrades and Expansions

19.  Treatment and Capacity aren’t the only issues to be addressed  Odor, Noise, and Aesthetics are additional issues  These have been successfully addressed at JCEC  No odors beyond 25 Feet from any building  Average of 10 dBA reduction in ambient sound level from before construction to after construction  Architecture and Landscaping used to blend into neighboring locations Facility Upgrades and Expansions

20. Game Creek Improvements Extreme Makeover! Recent Capital Improvement Projects  New MCC & VFDs  Replacement of pumps, motor control center and control system  Bypass pumping connections  New backup generator  New odor control system  Landscape Improvements  $652,250.00 budget

21. South Fulton Pump Station Odor Control  Upgrades at Seven Pump Stations  $2,218,777 Budget Recent Capital Improvement Projects

22.  Regulatory Changes are addressed during NPDES Discharge Permit Renewals  Includes: flow quantity, pollutant identification, loading and concentrations  Changes drive plant expansions & upgrades  All Regulatory & NPDES Permit requirements are met or exceeded.  The KPI is the “Wastewater Effectiveness Rate”  The goal is 100% treatment  Current Wastewater Effectiveness Rate is 99.62% Regulatory Issues

23.  Watershed Protection Plan  Completed February 2006  Assessed treatment level impacts upon receiving water bodies  Implemented MS4 & annual storm water permit for all wastewater facilities o Storm water is monitored per permit Regulatory Issues

24. Wastewater Treatment Systems

25.  Plant operations & maintenance staff are constantly trained to advance knowledge and maintain certifications.  Certification status is updated monthly  Backup systems, equipment & software used for monitoring wastewater facilities  CMMS, SCADA, operations data analysis & storage, web-based telemetry, onsite & remote access Wastewater Treatment Reliability

26.  Beneficial reuse of bio-solids  Johns Creek Environmental Campus sludge is sent to compost facility Treatment Plants

27.  CMOM program approved by Georgia EPD  Audits successfully completed in 2011 & 2012 by EPD  Internal audits are done on annual basis o City Works and Datastream 7i are the CMMS software used Capacity, Maintenance, Operation, and Management (CMOM)

28.  Data is used to determine capacity needs for wastewater facilities and collection system and to keep track of maintenance programs, equipment & inventories  Inspection & repairs of:  Creek crossings  Manholes  SSOs  Sanitary Sewer Lines & easements  Sewer system cleaning and chemical root control programs CMOM

29. Infiltration & Inflow Reduction  Majority of sewer lines have been visually inspected via CCTV  Defects given a PACP coding & ratings  Used to prioritize corrections  Ongoing inspection & repair program to ensure reduction of inflow & infiltration

30. CMOM  Root Control  To apply chemical root control to sewer lines and manholes to kill root growth  Plan to treat up to 80,000 feet of sewer line per year  Cleaning  To remove sedimentation, debris, and grease from sewer lines and manholes  Plan to clean up to 110,000 feet of sewer line per year

32. GIS and Computerized Maintenance Management System (CMMS)

33.  Maintain inventory of Water, Waste Water, and Storm Water systems  Complete system that supports asset management, spatial analyses related to the watersheds, and operational maintenance and construction  Includes material, diameter and size, installation date, status, location notes, special conditions, special functionality, etc.  Updated continuously as repairs to the system are completed, the system is expanded, the system is reconfigured, or supporting information is discovered  Field survey work is continuously in process to improve or record the locations of assets Geographic Information System

34. The work order management system is tied directly to the GIS. This gives all work orders a place on the map and an asset in the system for tracking purposes. CMMS Work Order Management

35. Reports are generated from the work orders that track productivity, KPIs, and assist in managing the work that must get done. CMMS Work Order Management

36.  Fats, Roots, Rags, Oils, and Grease (F.R.O.G.)  Educate about proper disposal and maintenance  Provide information about wastewater treatment standards and practices  Program is offered to schools throughout the County & information is available on Fulton County’s website  Promote internships & have a dedicated education center at Johns Creek Environmental Campus Public Education and Outreach

37.  Fulton County Code of Laws establishes:  Prevention of installation in floodplains & stream buffers  Limitations on density in siting septic tanks  Residents may petition for sewer connection  Connection to sewer is not required unless the septic system has failed.  Fulton County uses the Garrison software called Digital Health Department. For septic tank conversion tracking purposes, files are organized alphabetically by address.  Pumped septic tank waste is accepted at the Camp Creek WRF  Public Education plays a key role in:  Proper use  Inspection, Maintenance & Cleaning  Staff attends community meetings, provides information via the Environmental Health webpage Septic Tanks

38.  Program allows for monitoring and reducing pollutant load and hazardous substances being introduced into the collection system and treatment plants.  Guided by Fulton County’s Sewer Use Ordinance.  EPD approved Industrial Pretreatment Program.  Details, Sewer Use Ordinance, & permit applications available through Fulton County’s website Industrial Monitoring and Commercial Pretreatment

39.  This program was created to meet a State and Federal regulatory requirement to monitor what industries discharge into the County sewer system  The Industrial Monitoring section issues permits to industries to limit the pollutants discharged into the sewer system, inspects the industries for compliance with County guidelines, and takes action against industries that violate their permits  34 Permitted (significant) industrial users  31 Non-permitted industrial users Industrial Monitoring

40.  Monitoring & inspection of approximately 1,805 commercial waste generators & pretreatment systems  Pretreatment systems are grease traps for restaurants, schools, churches, hotels, etc., and oil separators for car maintenance and car/truck washes  All new commercial development with a pretreatment system must be reviewed to ensure it meets County standards by the commercial pretreatment program before discharging to Fulton County sewer  This includes plan review and inspection  Separators discharging to sanitary sewer are covered under this program Commercial Pretreatment

41.  All commercial waste generators with a grease trap, oil separator or sand trap that discharge to the county sanitary sewer system are required to have a permit for their pretreatment systems.  Inspections  Quarterly & random inspections  Verify maintenance is done by owner  Nearby grease traps of F.O.G. induced spills  Shares information with sewer maintenance Commercial Pretreatment

42.  Available to commercial & industrial users of Fulton County’s sewer system  Removes sewer service fee on flows not sent into the collection system  Customer must divert at least 25% or more of their annual water consumption  Program is useful for cooling tower operations or manufacturing processes which consume potable water  22 properties participating in program  Approximately 47,644,640 gallons diverted for an amount of $61,540.76 Diverted Water Program
