Liquid wastes from printing processes such as inks, fountain wash solutions, rinse water from equipment that has been washed in solvent, flexography plate acid bath solutions, etching solutions and wash-out solutions can negatively affect sewer pipes, treatment works, septic systems and pose a health hazard to humans and to the environment.

Wastewater from printing operations can also contain quantities of solids, heavy metals, oils and grease and chlorinated solvents that may be toxic even in very low concentrations.

Printing chemicals can be a health hazard; they can also create hazards such as fire, explosion, air and water pollution, corrosion of pipes or damage to sewage treatment facilities or septic systems. Damaged pipes can allow rain and ground water in to sewer lines or waste to escape into the environment.

Waste generators are required to comply with all federal, provincial, municipal and regional regulations for proper waste disposal.

Under the Provincial Environmental Management Act and the Federal Fisheries Act, a waste generator may be held liable for any contamination or harm created as a result of the deposition or discharge of that waste. Proper disposal and management of wastes significantly reduces risks of environmental contamination and the requirement for remediation.

Proper storage, inventory of products and wastes, spill response plans and employee education on managing dental wastes are key factors in keeping our receiving waters clean.

All industrial, commercial or institutional facilities that discharge non-domestic wastewater to the sanitary sewer system operated by the CRD must follow the requirements of CRD Bylaw 2922 - Sewer Use Bylaw. The printing sector, as with many other sectors, have specific requirements under a code of practice with in the Sewer Use Bylaw.

Code of Practice for Printing Operations describes the requirements and conditions for preventing or limiting the discharge of prohibited and restricted wastes into the sanitary sewer system.

The following is a summary of the key requirements under the Bylaw and Code of Practice (Schedule "Q").

• Not discharge prohibited waste into the sewer system
• Not discharge wastewater which contains:
  • rinse water from equipment that has been washed in solvent
  • inks and fountain solutions
  • flexography plat acid bath solutions, etching solutions and wash-out solutions
  • cleaning solvents
• Install treatment works to treat liquid wastes or collect and transport prohibited and restricted wastes for offsite management
• Perform inspections and maintenance of treatment works
• Create a spill response plan
• Maintain written records treatment work maintenance and proper waste disposal
• More information on the Code of Practice for Printing Operations and the Sewer Use Bylaw

Please submit a Waste Discharge Assessment Form if you are unsure whether this code of practice applies to your business.

Although compliance with Sewer Use Bylaw may help you meet other municipal, provincial or federal conditions, other agencies may have additional requirements. Use BizPaL to help you identify additional permits and licenses required to operate your business.

Prevent stormwater contamination and protect our aquatic environment by ensuring that printing wastes do not enter the storm drain network (which includes ditches, catch basins and roadways, etc.).

• Educate staff about the spill prevention and response.
• When hosing or washing equipment or surfaces outside, do not let the runoff water enter the storm drain.
• Regularly inspect and maintain any parking lot catch basins.
• Store waste products under covered areas with appropriate spill containment.

If you operate on the Saanich Peninsula (North Saanich, Central Saanich and Sidney) then you need to know about Bylaw No. 4168 requirements.

Liquid waste haulers can be hired to responsibly manage any fluids associated with printing.

• Trucked liquid waste directory

It is important to note that the waste generator retains ownership of the waste even after it has been turned over to a waste hauler. This means the generator can be held responsible for the consequences of a spill or improper disposal of waste.

For that reason it is important to ensure that the hauler you hire can demonstrate that they are:

• properly licensed;
• have properly trained staff; and,
• will deal with your waste in a safe, responsible, legal and diligent manner.
