Overview of Illicit Discharge and

Elimination (IDDE)

Paul Rosile, Director of Environmental Health & Assistant Health Commissioner

Franklin County Public Health

IDDE Topics Include

• Explanation of public health risks

• Requirements of homeowners with HSTS

• Identify and eliminate failing HSTS

• Where are the public health risks

• When to expect these requirements

What are the Public Health Risks?

• Untreated or improperly treated sewage can contaminate:– drinking water supply– drainage ditches– streams, rivers and lakes

• When household sewage treatment systems fail, untreated sewage is discharged into the environment.

What are the Public Health Risks?

• Contact with human waste can pose health risks because it can carry disease-causing organisms.

• Health risks are directly tied to exposure and ingestion of untreated sewage.

• The young, the old and those with chronic conditions are at higher risk.

Avoid Exposure

• Do not allow kids and pets to play in water that looks and smells like sewage.

• Do not swallow or get water from ditches or streams in your mouth or nose.

• If you are in those types of areas, wash hands thoroughly with soap and water.

The aeration system was invented in the 1970’s as a treatment option for

households not connected to the sanitary sewer

Requirements of Homeowners with Household Sewage Treatment Systems

Paul Rosile, Director of Environmental Health & Assistant Health Commissioner

Franklin County Public Health

Old Aeration System

Aeration chamber

Maintaining Aeration Systems

• Annual inspection by Franklin County Public Health (FCPH) or a maintenance contract.

• Properly operating motor.• Properly operating air intake.• Tank pumped based on manufacturers

recommendations.

Septic Tank and Leach Field Systems

Maintaining Septic and Leach Field Systems

• Tank pumped based on manufacturers recommendations.

• Functional baffles.• Check for sewage or ponding in your

yard.• Ensure leach field is not connected into a

farm tile, ditch or storm sewer.

Why HSTS Fail

• Aeration, septic and leach systems fail because: – Unsuitable soil conditions– Improper design and installation– Inadequate maintenance– Age of the system– Amount of water use

Septic and Leach Field System Failures

Identify and Eliminate Failing HSTS

Paul Rosile, Director of Environmental Health & Assistant Health Commissioner

Franklin County Public Health

Priority 1

• If sanitary sewer is available and accessible, homeowners will be ordered to abandon their HSTS and connect.

– Whether the system is operating correctly or not, the homeowner will be required to connect.

– Required by FCPH regulations and state law.

Priority 2

• Identify discharging HSTS not issued permits by FCPH.

• Removal of those systems will be required. This may include:– Replacing with a soil absorption system.– If that is not feasible, replace with a new

system covered under an Ohio EPA general NPDES permit.

Norweco Best Available Technology (BAT) meets OEPA

NPDES permit for discharge standards

Jet BAT meets OEPA NPDES permit for discharge standards

Priority 3 and 4

• Identify HSTS discharges causing “obvious” or “suspicious” pollution.– Verified evidence that sewage pollution is

causing a public health nuisance.– Identified conditions that could have been

caused by contamination.

• FCPH will determine if a failed HSTS is causing a nuisance.

Definition of a Public Health Nuisance

1) HSTS cause a public health nuisance when any of the following situations occur:

a) Not operating properly due to a missing component.

b) Incorrect settings.c) Mechanical or electrical failure (motor not

running).

AND, timely repairs of these situations are not made after notice to the property owner by the Board of Health.

Definition of a Public Health Nuisance

2) There is a blockage in a known sewage treatment system component or pipe that causes a backup of sewage or effluent affecting the treatment process or inhibiting proper plumbing drainage.

Definition of a Public Health Nuisance

3) There is ponding or bleeding of liquid onto the surface of the ground or into surface water. The liquid has a distinct sewage odor, a black or grey coloration, or the presence of organic matter and any of the following:

a) a dye test identifying effluent from an HSTSb) samples show fecal coliform at a level that is equal or greater

than five thousand colonies per one hundred milliliters of liquid

c) samples show more than one thousand thirty e.coli counts per one hundred milliliters of liquid

Current Annual Inspection Program

• We inspect individual aeration system for a nuisance:

- if the system is not operating properly due to a missing component, incorrect settings, or a mechanical or electrical failure.

- if there is a blockage in a known sewage treatment system pipe that causes a backup of sewage or inhibits drainage.

New Stormwater Pollution Investigations

• FCPH will inspect storm sewer outfalls for the presence of sewage during our dry weather screening.

– If there are "obvious" or “suspicious” signs of sewage pollution, FCPH will investigate the aeration or septic systems connected to the storm sewer for nuisance conditions, and will abate the nuisance if found.

Priority 3 and 4, continued

• If the system is causing a nuisance, homeowners will be required to abate the nuisance. This may include:– Replacing with a soil absorption system.– Repairing existing system.– If that is not feasible, replace with a new system

covered under an Ohio EPA general NPDES permit.

• If there is no nuisance, no further action is needed.

Where are the Public Health Risks?

• Every township in Franklin County.

• In urban areas.

• In rural areas.

• Along roadways.

• Along streams.

How Do We Know the Risks Exist?

• Nuisance and pollution complaints.

• Maintenance reports by HSTS owners.

• Annual inspections performed by FCPH.

• Observation during roadway

construction.

• Dry Weather Screening for NPDES

permit.

What is Dry Weather Screening?•In-field evaluation of MS4 components.

How We Summarized Health Risks?

• Use of existing records.

• Use of existing data sets.

• Development of new data sets.

• Extensive use of G.I.S.

GIS: (Geographic Information System)

GIS is a computer-based technology developed around geo-spatial information

(having a location on the earth's surface). GIS allows for data development,

management, and analysis as well as the presentation of the data in a variety of

visual formats including maps, database tables and charts.

How We Summarized Health Risks?Franklin County Public Health and Franklin

Soil and Water Conservation District have created a ranked list of “Identified Areas of Concern.”

The following metrics were used within a GIS to identify and rank these Areas of Concern.- Dry Weather Screening

How Long Will It Take For FCPH To Identify and Eliminate Failing HSTS Causing Public Health Nuisances?

Paul Rosile, Director of Environmental Health & Assistant Health Commissioner

Franklin County Public Health

How Long Will It Take?

• It will take years.

• FCPH will begin investigations in the first quarter of 2012.

– Start with the highest ranked identified areas of concern.

– Work through to the lowest ranked area.– Use the prioritized approach in each area.

What Will It Cost?

• Repair - $2,000 – $8,000.

• Replace - $15,000 - $20,000, depending on the type of system.

• Tap into sanitary sewer - $5,000 - $10,000, depending on the distance from the home to the tap and other constriction costs.
