b. Locate and design the facilities using best conventional techniques to ensure mass stability, 

 prevent the release of acid or toxic materials, and attainment conservation strategy goals. If 

 the best conventional technology is inconsistent with attainment of conservation strategy goals, 

 prohibit such facilities within the riparian area, or 300 ft from the stream. 



c. Monitor waste and waste facilities to confirm predictions of chemical and physical stablity, 

 and make adjustments to operations as needed. 



d. Reclaim waste facilities after operations to assure chemical and physical stability necessary for 

 acheiving conservation strategy goals. 



e. Require reclamation bonds to ensure long-term chemical, physical, hydrological, and 

 biological stability of mine waste facilities. 



MM-5 For leasable minerals, prohibit surface occupancy within 300 ft of the stream, unless they can 

 be conducted in a manner compatible with acheiving conservation strategy goals. Adjust the 

 operating plans of any existing contracts to eliminate impacts that are inconsistent with 

 attainment of conservation strategy goals. 



MM-6 Sand and gravel mining in riparian areas should not be conducted unless it can be done in a 

 manner consistent with acheiving conservation strategy goals. 



MM-7 Develop inspection and monitoring requirements for mineral activities. Evaluate the results of 

 inspection and monitoring to modify mineral plans, leases, or permits as needed, to eliminate 

 impacts that are inconsistent with attainment of conservation strategy goals. 



Recreation management 



Recreation management guidelines RE-1 through 4 are intended to avoid disturbance of harlequin ducks 

 by boaters during the breeding season. This can be especially detrimental on smaller streams where it 

 is difficult for harlequin ducks maintain a comfortable distance between themselves and the boats 

 without being displaced up- or downstream. Recreation management guidelines RE-5 through RE-7 

 are intended to reduce or avoid increases in disturbance by other recreational activities in and along the 

 stream during the harlequin duck breeding season. RE-5 and RE-6 are also intended to maintain 

 nesting and security habitat in riparian areas. 



RE-1. Discourage expansion of boating activities on occupied or potential harlequin duck breeding 

 streams or stream reaches currently receiving low or no boating use. Control access through 

 methods such as not plowing access roads during the breeding season or where necessary, 

 closing roads that would provide boater access to remote streams. Implement seasonal boating 

 closures where use cannot be managed through access restrictions. 



RE-2. Prohibit commercial boating permits, boating competitions, and instructional schools in areas 

 currently without them; this should include transportation of private boating parties and/or 

 their equipment at the beginning or end of their trip by commercial outfitters.
