In addition to the general criteria set forth in Section 12.40.10, the following additional criteria apply to any development of major new domestic water and sewage treatment systems or major extensions of existing domestic water and sewage treatment systems:

1. The Project shall be reasonably necessary to meet projected community development and population demands, or to comply with regulatory or technological requirements.
2. To the extent feasible, wastewater and water treatment facilities shall be consolidated with existing facilities within the area.
3. New domestic water and sewage treatment systems shall be constructed in areas which will result in the proper utilization of existing treatment plants and the orderly development of domestic water and sewage treatment systems of adjacent communities.
4. The Project shall be permitted in those areas in which the anticipated growth and development that may occur as a result of such extension can be accommodated within the financial and environmental capacity of the area to sustain such growth and development.
5. The Project does not adversely affect either surface or subsurface water rights of upstream or downstream users.
6. Adequate water supplies, as determined by the Colorado Department of Public Health and Environment, are available for efficient operational needs.
7. Existing domestic water treatment facilities or systems must be at or near operational capacity.
8. Age of existing water systems, operational efficiency, state of repair or level of treatment is such that replacement, if applicable, is warranted.
9. The Project will not decrease the quality of peripheral or downstream surface or subsurface water resources below that most recently designated by the Colorado Water Quality Control Commission for those waters.
10. The Project or its associated collector or distribution system or new service areas will not violate federal or state air quality standards.
11. The Project or its associated collector or distribution system will not significantly deteriorate aquatic habitats, marshlands and wetlands, groundwater recharge areas, steeply sloping or unstable terrain, forests and woodlands, critical wildlife habitat or other wildlife protection areas, big game migratory routes, calving grounds, migratory ponds, nesting areas and the habitats of rare and endangered species, public outdoor recreation areas, and unique areas of geologic, historic, or archaeological importance.
12. The Project or its associated collector or distribution system will not significantly degrade existing natural scenic characteristics, create blight, nor cause other nuisance factors such as excessive noise or noxious odors.
13. The Project or its associated collector or distribution system will not create an undue financial burden on existing or future residents within the development area and source area. The cost of securing an adequate supply of water for existing and future needs of the residents of this County shall be considered in determining whether an "undue financial burden" will result.
14. The Project will not remove significant amounts of water from open space or conserved lands in Pitkin County.
15. The Project complies with the County’s Scientific/Social Framework for Managing Impacts of Trans-Basin Water Diversions to Protect Stream Health in Pitkin County, Colorado, in accordance with the guidelines described therein.
