Section 20.02.01.031 - CUMULATIVE WATERSHED EFFECTS01.Purpose. In accordance with Section 38-1305(8), Idaho Code, the Department has developed methods for controlling cumulative watershed effects (CWE). The methods and procedures are described in the department manual entitled "Forest Practices Cumulative Watershed Effects Process for Idaho." Proper application of this process will help ensure watersheds are managed to protect water quality so that beneficial uses are supported. This rule describes how the process is to be implemented on forest land.02.Process Application.a. Application of the CWE process and any resulting site-specific BMPs are encouraged but not mandatory.b. The process may be initiated by either the Department, a watershed advisory group, or an individual landowner or group of landowners that collectively own at least twenty-five percent (25%) of the forested land in a watershed. In any case, a reasonable effort will be made to notify forest landowners within the watershed, and the landowners will be given the opportunity to participate in the process.c. The Department must be notified prior to the initiation of the CWE process.d. The Department will review and approve the watershed assessment and CWE site-specific BMPs for compliance with the Act.03.Site-Specific BMP Implementation. Site-specific BMPs developed by a watershed advisory group are encouraged and applied on a voluntary basis.Idaho Admin. Code r. 20.02.01.031
