(viii) Include provisions authorizing temporary short-term deviations from the Operating Manual for emergencies and unplanned circumstances, as described in applicable Corps of Engineers regulations, including § 222.5(f)(4) and § 222.5(i)(5) of this chapter, and Engineer Regulation ER 1110-2-8156 “Preparation of Water Control Manuals.” However, deviations shall be minimized by including planning for flooding events caused by rainfall and hurricane events, as well as by including a drought contingency plan.
- (A) Emergency deviations. Examples of some emergencies that can be expected to occur at a project are: drowning and other accidents, failure of the operation facilities, chemical spills, treatment plant failures and other temporary pollution problems. Water control actions necessary to abate the problem are taken immediately unless such action would create equal or worse conditions.
- (B) Unplanned circumstances. There are unplanned circumstances that create a temporary need for minor deviations from the Operating Manual, although they are not considered emergencies. Deviations are sometimes necessary to carry out maintenance and inspection of facilities. Requests for deviations for unplanned circumstances generally involve time periods ranging from a few hours to a few days. Approval of these changes shall be obtained from the Division Engineer.
