5 Colo. Code Regs. § 1002-74.5
Jefferson County, Clear Creek County, Park County, municipalities, and districts in the Bear Creek Watershed shall implement best management practices for control of erosion and sediments. The Commission shall review the performance in implementation of existing erosion and sediment control programs by the counties, municipalities, and districts at each triennial review of this regulation. The Association will identify nonpoint source management practices and programs in the management plan and annual report.
The Association may include in the management plan and annual reports a listing of those non-urban areas where existing or planned development relies on individual sewage disposal or onsite systems as mapped by Jefferson County, Clear Creek County, or Park County. The Association may recommend that counties develop a septic management plan. Septic management plans should be designed to protect watershed surface and groundwater quality and will not target individual onsite systems.
