The Ordinance – Steps in Achieving Control

• Identify the FOG generators and effluent quantities
• Regulate the discharge method
• Introduce and enforce control devices (GDO)
• Regulate and enforce proper usage of the control devices
• Offer incentives; positive and negative
• evaluate effluent limits => test methods can be unreliable (100 vrs 150 mg/L)
• Offer guidance => establish Best Management Practices
• Increase inspection and enforcement procedures, incl. fines and business

closures

• Specify control device usage AND control device monitoring + maintenance
• Prolong maintenance intervals if control device used properly

• Identify the FOG generators and quantities
• Hot Spots and cost identification

1. Liquid Waste Haulers must have valid operating permits issued by MDC 2. Monthly reports by the FSE on pump-outs must be filed by the liquid waste hauler 3. Monthly reports must be kept on file by the FSE 4. Mandate cleaning cycle of the control devices 1. Gravity => every 60 days latest, or prior to 25% of operating capacity 2. Hydromechanical => every 30 days latest, or prior to 25% of operating capacity

Example: Miami-Dade County

• Mandate Interceptor Monitoring Device to ensure proper maintenance
• FSEs physically separated from their interceptor require a monitoring device

The Ordinance – Steps in Achieving Control

• Offer Positive Incentives
• Financial incentive => potential

to save pump-out cost if proof that control devices properly maintained

• Offer Incentives
• Financial incentive => potential to save pump-out cost if proof that control

devices properly maintained

• Extends pump-out periods up to 180 days

The Ordinance – Steps in Achieving Control

Example: Miami-Dade County

• Offer Negative Incentives
• Increase inspection, enforce procedures and compliance
• Educate, and if necessary enforce
• Criminal and Civil Action (last step, but possible)

• Offer Negative Incentives
• Threaten imposed monitoring

Captured Data & Knowledge

Interceptor Monitoring Device (IMD) - Regulatory

In the event the grease interceptor is located remote from the FSE, e.g. more than 100 feet horizontal distance away, or on another floor, the use of an IMD is mandated to ensure proper knowledge of grease levels.

Interceptor Monitoring Device (IMD) - Financial

The cost of pumping out gravity grease interceptors varies on a number of factors depending on size of the interceptor, quantity of interceptors, location of individual sites, frequency of pump-

• uts, contractual negotiations (e.g. multiple sites).

In general, an average pump-out will cost approx. USD 0.25 per gallon plus the transport charge. With pump-outs mandated at 60 days at the latest, and assuming a flat rate of e.g. $50 per transport, this translates to:

Without IMD With IMD

750 gallon => $1,425.00 per year => $475.00 p.a. 1250 gallon => $2.175.00 per year => $725.00 p.a. 1500 gallon (two interceptors) => $2,550.00 per year => $850.00 p.a. 2500 gallon (2-3 interceptors) => $4,050.00 per year => $1,350.00 p.a. 5000 gallon (quite a few interceptors) => $7,800.00 per year

• > $2,600.00 p.a.

Remote Ultrasonic Monitoring - FOGMonitor

Communicating, displaying, logging and reporting the data

• Wireless transmission of the data through RF

technology

• The data is wirelessly transmitted to the

control display allow the user to see the content levels

• When the FOG volume reaches a pre-set

amount a warning alerts the user indicating that a pump-out is required

• Logging capabilities allow for historical

analysis, as well as report generation

• Quick & Easy Install – essentially plug & play
• Single mounting point for communications box
• Durable and reliable float sensor
• Wireless transmission, no external power source required for

sensor

• Logging function, allows for ease-of-reporting

Remote Ultrasonic Monitoring - FOGMonitor

Decision Time – Analyzing the Data

Compliance doesn’t automatically mean compliance.

An interceptor remaining under 25% operating capacity may still be discharging FOG into the sewer lines. An interceptor in excess of the 25% FOG rule may not be discharging any FOG at all. Knowing the individual levels in conjunction with Best Management Practices is key in streamlining effluent handling.

• Better Regulatory Compliance
• Lower Operating Costs

Best Outcome

Regulatory Compliance => more effective use of resources, both in manpower and equipment cost Cost Savings => FSEs can potentially save 1000s of $$$ Streamlined Pumper Efforts => less wasted resources on pick up and processing The data allows the regulator to evaluate the program specifics while the FSE can evaluate the regulations effectiveness. Together this can lead to program improvements and drive down costs to all parties.
