Long description for Figures

Figure 1

A flowchart shows the structure of the document. The start of the flowchart is "regulatory framework" found in chapter 2. The flowchart divides in two paths: "engines" and "persons" affected by the regulations (chapters 3 and 4 of the document). These two separate paths join after leading to the item "regulatory requirements" described in chapter 4 of the guidance document. The next and last item in the main path of the flowchart is called "compliance and enforcement" in chapter 11 of the document. Under the item "regulatory requirements", there is secondary path leading to an item called "additional details" where chapters discussing the national emission mark, emission standards, evidence of conformity, importing an engine, other obligation and special engine cases are listed.

Figure 3

A flowchart shows the procedures to follow for Canada-only engines. The flowchart starts with a description of the information and data that a company must provide to the Minister. The next step in the flowchart is a decision point where the data is assessed by Environment Canada. Environment Canada may decide that more data is needed for the assessment in which case the company repeats the first step of the flowchart. Environment Canada may also deemed the evidence of conformity to be satisfactory and the procedure continues with a letter sent by the Minister. This letter and the information provided earlier become the evidence of conformity for the engines. The next step depends on the origin of the engine. If the engine is imported, the company must apply a compliance label (or a national emission mark if it is authorized to do so) and an engine information label. If the engine is manufactured and transported in Canada, the company applies the national emission mark and an engine information label.

Figure 4

This is a flowchart explaining the standards applicable to a replacement engine. The flowchart starts with a question to which the answer can be yes or no. Each of these answer leads to another yes or no scenario. The first question is "is there a replacement engine manufactured to the specifications of a model year later than the model year of the original engine and with the physical characteristics necessary for the operation of the machines?" If the answer is yes, the flowchart leads to the question: "were there emission standards applicable to an engine manufactured to the specifications of the model year of the replacement engine?" If the answer is yes, then the replacement engine must conform to these standards and is answer is no, then the the replacement engine must conform to the manufacturer's specifications. If the answer to the first question in the flow chart is no, then the flowchart leads to the question: "were there emission standards applicable to the original engine?" If the answer is yes, then the replacement engine must conform to these standards and is answer is no, then the the replacement engine must conform to the manufacturer's specifications.
