Or. Admin. Code § 629-620-0800 - Notification of Community Water System Managers When Applying Chemicals

(1) The purpose of this rule is to ensure that community water system managers are appropriately notified of planned chemical operations so that they can coordinate their monitoring activities with planned operations.

(2) This rule applies to community water systems where the surface water drainage area upstream of their intake is 100 square miles or less. The State Forester shall maintain a list of community water systems for which notification is required. A community water system with a drainage area of more than 100 square miles upstream of its intake may request to be added to the list based upon its ability to conduct effective monitoring in the watershed. The list shall be available at department field offices where notifications are submitted.

(3) When chemicals will be aerially applied within 100 feet, or applied from the ground within 50 feet of domestic portions of Type F, Type SSBT or Type D streams, and the water use is by a community water system as designated under section (2) of this rule, the operator shall notify the water system manager of a planned chemical operation at least 15 days before the operation commences.

(4) The operator shall provide the following additional information before commencing the operation if requested by the manager of the affected water system at the time of notification required in section (3) above:

(a) The application technology that will be used;

(b) Practices that will be followed to minimize drift toward the stream;

(c) Any monitoring efforts that will be conducted by the landowner; and

(d) The planned time schedule for the application.
