Waste Management

 

COA (Certification of Approval)

Following the unique Extox recovery process, the Ontario Ministry of Environment was convinced to issue one of the few delisting permits ever granted under Regulation 558/00 – the stringent new body of law that requires waste handlers to take full responsibility for all materials they receive. Under this regulation, waste handlers must ship out the same quantity of hazardous material they receive – unless the handler renders that material benign.

The Ontario government acknowledges that the Extox process is sound and by recovering chemicals from filters for re-use, the Extox process effectively removes this potentially hazardous contaminant from the waste stream. As a result, our customers have an opportunity to benefit from advances in waste recovery technology.

A complete copy of the delisting permit is available upon request from Extox. The Ministry of Environment and Energy (MOEE) maintains an Environmental Registry that includes amendments to the Certificate of Approval (COA), which is available online

Audit Package

Air CertificateExtox Industries Inc. operates a facility equipped with carbon scrubbers that controls emissions from the building, which complies with Extox’s air certificate (#: 8-3218-94-006).

Transport PermitExtox Industries is licensed under the Ministry of Environment, which permits Extox to pickup and transport hazardous waste to its secure facility. The transport permit is identified by the number A841483.

Insurance

Extox Industries is unique in many ways; however, what differentiates Extox from its competitors is the liability insurance provided to its customers. This ensures that the waste produced in the dry-cleaning process is not a liability to the business. As a result, the customer can have peace of mind knowing they are safe from the destructive costs (up to 2 million dollars) of a spill of accident. The full insurance plan can be requested from Extox.

 

Dry Cleaning Regulated Waste

You must store all PERC, residue and waste water containing PERC in closed containers. Any container holding PERC, waste water and/or residue, including stills as well as button and lint traps, must be kept closed except when you need to access them. In addition to storage, as an owner and/or operator of a dry cleaning facility, you have the obligation to prevent PERC spills. In the event of a spill, you must contain the spill and prevent PERC from getting into the environment by using a second containment system. This means placing the container or machine containing PERC inside another container that will contain any spills. 

Secondary Containment System Requirements:

  • Be PERC-impermeable 
  • Encompass at least the entire surface under each dry cleaning machine, tank or other container containing PERC, waste water or residue [section 5(f)(i)];
  • Be large enough to hold at least 110% of the capacity of the largest tank or container placed inside it 
  • You must also keep PERC-resistant drain plugs readily available to seal all floor drains that PERC, waste water or residue could enter in case there is a spill.

Secondary Containments typically, means placing the dry-cleaning machine, waste water bucket, sludge drum, waste water treatment system, etc. inside another container, such as a spill tray, pan, platform or pallet. If the dry cleaner does not have a spill tray then Extox Industries can provide the option of purchasing a drum in a drum to uphold the regulations for secondary containment.

When buying new machinery from Extox Industries Inc. you can be guaranteed that all regulations are met with the machine, which ensures the customer does not meet any consequences with the ministry. 

Requirements for PERC recovery from machines

  • You cannot use transfer machines (machines with separate drums for cleaning/extraction and drying/aeration) or self-service machines.
  • Your machines must be equipped with a built-in refrigerated condenser and a PERC-water separator.
  • Your machines must not vent to the open air during the washing, extraction, drying and aeration cycles.
  • You must use a closed direct-coupled delivery system for PERC delivery.
  • Machines installed after July 31, 2003, must have a manufacturer’s design PERC consumption rating equal to or less than 6.2 L (or 10 kg) of PERC per 1000 kg of clothing cleaned. Machines installed or in use prior to August 1, 2003, do not have to meet this consumption rating.

If you own or operate a dry cleaning facility that uses PERC, you have to keep records concerning the purchase and disposal of PERC-containing waste, including receipts and accounting books. Other records may include journals, logs, letters, emails and other supporting documentation. Receipts and accounting book entries must be kept of every purchase of PERC, the shipping of waste water and residue to a waste management facility, and the on-site treatment of waste water. You need to keep these records for five years after the end of the year in which an annual report was filed. 

How to File Annual Reports:

Environment Canada provides a Mandatory Reporting Form for owners and operators of dry cleaning machines using PERC. More information regarding annual reports can found at 

Containers, tanks or dry-cleaning machines containing PERC, waste water or residue are stored within a secondary containment system that:

  • is impermeable to PERC
  • holds a volume equal to 110% of the largest tank or storage container
  • covers at least the entire surface under each dry-cleaning machine, tank or other container
  • PERC, waste water and residue are stored in closed containers (containers must have lids on them)
  1. PERC-resistant drain plugs are readily available to seal all floor drains in case of a spill
  2. Waste water (if not treated on site) and residue is transported at least once every 12 months to a waste management facility.
  3. All the waste water and residue that are within the dry-cleaning facility need to be transported.
  4. If waste water is treated on site, the waste water treatment system should have the required equipment.
  5. Dry-cleaning machines use the same drum for the washing, extraction, drying and aeration cycles
  6. Dry-cleaning machines are equipped with an integral refrigerated condenser .
  7. Dry-cleaning machines do not vent to the atmosphere during the washing, extraction, drying and aeration cycles
  8. Dry-cleaning machines have an integral PERC-water separator
  9. Dry-cleaning machines use a closed direct-coupled delivery system for PERC delivery
  10. Spotting agents that contain PERC are not used
  11. Submit Annual Report for Dry Cleaners by April 30th each year
  12. Maintain books, records and copies of reports submitted for at least five years

Dry Cleaning Non-Regulated Waste

With new technology being used in the dry-cleaning industry many business owners choose to use alternative solvents instead of PERC. Alternative solvents such as DF-2000, Extox Blend, and Sensene are categorized as non-regulated waste; however, this does not indicate that the waste is without regulation. Non-regulated waste can also be identified as Liquid Industrial Waste (LIW), which includes requirements for proper disposal.

LIW are wastes from industrial or commercial sources that are liquid waste, but not hazardous waste. For registration purposes, the criteria for determining whether a waste is liquid is the slump test, which is set out in Schedule 9 of Regulation 347. While LIW must be registered with the MOECC, they are not subject to the same level of regulation as hazardous wastes. Moreover, while LIW must be managed at an approved facility, they are not subject to land disposal restrictions.
