4. Overview

4.1 Effluent from wastewater and stormwater systems is:

  1. an important consideration in water use and protection; and
  2. a significant environmental aspect in the DND EMS.

4.2 The DND and the CAF own and operate wastewater and stormwater systems at Defence establishments and on military equipment. Whether effluent is managed onsite or conveyed to municipal sewer, it is ultimately discharged to the receiving environment. Both the Fisheries Act and Migratory Birds Convention Act, 1994 prohibit deposition of deleterious substances. Under the Fisheries Act, the Wastewater System Effluent Regulations further control effluent from certain systems to ensure that it:

  1. does not exceed specified concentrations of certain pollutants; and
  2. is not acutely lethal.

4.3 The federal, provincial and territorial governments, through the CCME, set goals for water quality in the Canadian Water Quality Guidelines (Canadian Water Quality Guidelines for the Protection of Aquatic Life and Canadian Water Quality Guidelines for the Protection of Agricultural Water Uses) for the protection of aquatic life and agricultural water uses.

4.4 Effluent may contain various substances at concentrations that could impact environmental health such as organic waste, nutrients, pathogens, suspended solids and metals. Effective management of effluent including preventative and standardized practices for the planning, monitoring, reporting and oversight of effluent enables the prevention and mitigation of related environmental impacts.

4.5 The DND and the CAF must manage effluent in line with federal legislative requirements and, if appropriate, international, provincial, territorial and municipal legislative requirements, including the Canadian Water Quality Guidelines.

Purpose

4.6 The purpose of this DAOD is to provide direction on effluent from any wastewater or stormwater system relating to a Defense establishment or military equipment managed with public funds that may be discharging to the environment or to a municipal sewer (sanitary, storm or combined). Examples include:

  1. wastewater systems such as pipes, lagoons, oily water separator treatment plants and systems; and
  2. stormwater systems such as ditches, oil and grit interceptors, and ponds.

Note – In this DAOD, effluent includes overflow and temporary bypass from a system,
and effluent from military equipment.

4.7 Effluent discharged into off-site municipal sewer systems is typically managed via agreements, though select requirements apply as described in this DAOD.

Exclusion

4.8 Effluent discharged from DND and CAF septic systems are:

  1. not included in the Canada-wide Strategy for the Management of Municipal Wastewater Effluent;
  2. excluded from this DAOD; and
  3. managed through ADM(IE) DAES standards.

Legal Implications

4.9 Many pieces of legislation define key federal requirements applicable to the management of effluent by the DND and the CAF, and third parties in Canada, including but not limited to:

  • Arctic Waters Pollution Prevention Act
  • Canadian Environmental Protection Act, 1999
  • Fisheries Act and Regulations
    • Wastewater System Effluent Regulations
  • Migratory Birds Convention Act, 1994
  • Fertilizers Act and Regulations
    • Fertilizers Regulations

Note – Relevant guidance documents are also available from ECCC and the CCME (see Section 14, References).

4.10 Provincial, territorial and municipal legislation:

  1. such as laws, guidelines and by-laws are applied at the design, implementation and decommissioning stages of wastewater and stormwater systems; and
  2. may also define requirements for effluent management along with international legislation when more stringent for military equipment outside Canada.

5. Operating Principles

5.1 The DND and the CAF must protect and conserve Canadian waters by adhering to legislative requirements as well as best management practices. Integrating the management of effluent with consideration for the receiving environment prevents and mitigates the impacts of effluent quality and quantity.

5.2 Among other key outcomes, integrated management helps to provide for the preservation of:

  1. habitat for fish and aquatic species;
  2. drinking water sources; and
  3. recreational activities in water bodies.

6. Planning

6.1 Effluent must be conveyed to existing municipal systems whenever capacity and condition of the system allows. If it is not possible, construction of new infrastructure systems must be treated as an asset class and must follow the PAD process. Both existing and new systems must adhere to ADM(IE) DAES standards. Procurement of military equipment must:

  1. follow the A-LM-007-100/AG-001, Supply Administration Manual process; and
  2. adhere to ADM(Mat) technical authority requirements.

6.2 Effective planning:

  1. enables due diligence and reduces potential impacts on the environment;
  2. enables compliance with environmental requirements including regulatory reporting; and
  3. integrates environmental considerations and related management measures into all stages of life‑cycle planning (procurement, design, implementation, decommissioning).

6.3 Key activities for:

  1. infrastructure include an ERA to:
    1. assess impacts to the receiving environment;
    2. establish related management measures; and
    3. subsequently develop an environmental monitoring and reporting program; and
  2. military equipment include:
    1. design specifications consistent with Canadian Standards Association; and
    2. international discharge requirements as outlined by the ADM(Mat) technical authority.

7. Implementation

Infrastructure

7.1 To meet EDOs, wastewater and stormwater systems, including work under contract must be operated in accordance with design specifications, and jurisdictional regulations and requirements (e.g. approvals and permits).

7.2 DND and CAF wastewater systems must have the necessary certifications.

7.3 System operators must:

  1. complete the required training and hold current certifications applicable to the wastewater systems under their responsibility;
  2. adhere to locally developed SOPs; and
  3. promptly execute maintenance and corrective action plans.

7.4 Any waste generated from a wastewater or stormwater system including sediment, sludge, biosolids and treatment media (e.g. filter bed sand and granular activated carbon), must be tested in accordance with jurisdictional requirements and ADM(IE) policy prior to transfer from Defence establishments (e.g. for disposal, land application, or other). If biosolids are processed and sold as fertilizer or soil supplement, prior registration and sampling is required in accordance with regulations and standards administered by the Canadian Food Inspection Agency.

Military Equipment

7.5 Military equipment must be operated in accordance with design specifications and federal and international requirements. Records must be maintained in accordance with regulatory discharge requirements.

7.6 CAF members responsible for operating treatment systems must possess the applicable military qualifications as specified by the L1 organization. System operators must adhere to locally developed SOPs and promptly execute maintenance and corrective action plans.
