Trucked Liquid Waste

The RDKS has developed a new policy for Trucked Liquid Waste that regulates the type of liquid waste accepted at RDKS waste facilities.

This policy was developed to provide liquid waste haulers with clear guidelines on what is acceptable at RDKS facilities, and also to protect our facilities and the surrounding environment.

ACCEPTED LIQUID WASTE

  • septage
  • pumpage from sewage holding tanks
  • sewage treatment plant sludge
  • pumpage from wash water and grit from drain sumps at automobile wash facilities (intended primarily for cars and light trucks) and parking lots

UNACCEPTED LIQUID WASTE (aka Other Liquid Waste)

  • catch basins
  • oil-water separators
  • grease trap waste from restaurants
  • shop floor drains and catch basins that potentially contain wastes such as fats, oils, and grease (FOG), and/or characterized as having contaminant concentrations exceeding the effluent standards for Hazardous Waste Facilities, as specified in Schedule 1.2, Column 3 of the Hazardous Waste Regulation
  • any prohibited waste listed in our bylaws

The unaccepted wastes listed above are prohibited because they are detrimental to our treatment systems and harmful to the surrounding environments.

If you're a Trucked Liquid Waste Hauler and want to dispose of liquid waste at an RDKS facility:

  • You must hold a valid Controlled Waste Permit approved for Septage or Acceptable Other Liquid Waste
  • You will need to submit monthly reports.

Fill out this form by the 7th of each month for the previous month's discharges. For example, if you dispose of waste in January 2025, the report must be submitted by February 7, 2025.

Frequently Asked Questions

Why has the RDKS made these changes?
The new policy aims to reduce the environmental and treatment impacts of handling hazardous and hydrocarbon-containing waste. Restricting these types of waste helps maintain safe facility operations and ensures compliance with environmental regulations.
What types of liquid waste are no longer accepted at RDKS facilities?

RDKS facilities will no longer accept liquid waste that exceeds hazardous waste limits or contains hydrocarbons.

Additionally, waste from catch basins, oil-water separators, grease-traps from restaurants, and shop floors that contain fats, oils, and grease (FOG) will also not be accepted.

How will the new policy affect liquid waste haulers?

All liquid waste haulers are now required to complete a new reporting form, detailing the type and source of each load.

This form ensures that only acceptable types of liquid waste are delivered to RDKS facilities.

What is FOG, why is it no longer accepted, and where does it go?

FOG stands for Fats, Oils, and Grease, which are commonly found in waste from restaurant grease-traps, shop floors, and oil-water separators.

These substances can lead to facility blockages and operational issues, so they are now excluded from accepted waste types in all RDKS facilities.

We recommend haulers reach out to specialized facilities authorized to handle hazardous or hydrocarbon-containing waste. A list of these facilities may be available from local environmental agencies or waste management services.

Will there be spot checks on liquid waste loads?

Yes, RDKS may conduct spot checks at the discretion of the Director. If RDKS suspects that a hauler may be attempting to dispose of unapproved waste, the Director will collect a sample of the liquid waste before disposal.

Haulers will be notified in advance if a sample collection is required.

Will I need to submit an analytical report characterizing the load content?

This may be required if you are submitting a controlled waste application to dispose of an accepted type of trucked liquid waste classified as “Acceptable Other Liquid Waste” and it includes sewage holding tank waste, sludge from sewage treatment plants, and wash water or grit from drain sumps at facilities intended for washing cars, light trucks, and parking lots. Industrial liquid waste and sludges are excluded.

Please note, however, that the Director may request an analysis report from a qualified professional if a new contaminant is suspected due to a change in waste type or source.

Where can I find the regulatory effluent concentration limits?
These limits are listed in Schedule 1.2, Column 3 of the Hazardous Waste Regulation.
