Environmental management systems for hog operations: Implementation guide
|Publication Date:||1 January 2005|
An EMS is a business tool that systematically applies general management principles to environmental issues associated with the activities, products, and services of an organization. CAN/CSA-Z771 applies management principles to environmental issues associated with hog operations.
A management system generally includes four components and a feedback loop
An EMS builds on the management system framework and typically includes the following elements:
(a) environmental policy;
(c) implementation and operation;
(d) checking and corrective action; and
(e) management review.
The internationally recognized EMS Standard, ISO 14001 (published by CSA as CAN/CSA-ISO 14001), specifies requirements for an organization's management framework but does not set environmental performance levels. Unlike management system standards, performance standards set obligatory threshold levels or objectives (e.g., watercourse setbacks) for an organization. CAN/CSA-Z771 can be best described as a management system/performance hybrid Standard, since it not only sets requirements for an organization's management system but also requires organizations to develop and implement performance-related environmental management practices (e.g., manure/nutrient, odour, and mortalities management planning). Figure 3 reproduces the clause headings of CAN/CSA-Z771.
Application of CAN/CSA-Z771 is voluntary. Hog organizations choosing to apply the Standard are expected to meet all of its requirements to be in conformance with it. Hog organizations implementing the Standard may choose to have their EMS registered by a nationally accredited third-party registration body. Hog organizations choosing to become registered to the Standard typically undergo an initial registration audit, yearly surveillance audits, and full registration audits every three years. Annex A provides further detail on registration procedures.
CAN/CSA-Z771, although specifically designed for hog operations, may be applied to operations containing hogs and other livestock. "Multi-livestock" organizations that choose to implement this Standard are expected to meet all of the requirements of the Standard, including the mandatory implementation of specific environmental management practices. In addition, multi-livestock operations choosing to implement the Standard would be required to identify and manage potential environmental impacts associated with livestock other than hogs.
