### S-3.1.01, r. 1 - Dam Safety Regulation

15. For the purposes of the assessment of the reliability of discharge facilities, the sections of a dam that do not contain such facilities are given the same rating as the section that does. If there are discharge facilities in more than 1 section of the dam, the lowest rating given to any section also applies to every other section of the dam. The same rule applies if there are discharge facilities in every section of a dam.
If there is more than 1 dam on the rim of a single reservoir, the structures that are not equipped with discharge facilities are given the same rating as the dam that is so equipped. If more than 1 dam is equipped with discharge facilities, the lowest rating given to any such dam or to a section of one of those dams also applies to every other dam on the rim. The same rule applies if there are discharge facilities in every section of each dam.
