Your project has been approved with the following special conditions: 1. All work conducted near the stream will be completed in an expeditious manner to avoid unnecessary impacts due to prolonged construction activity near the waterway; 2. Equipment and vehicles will be washed prior to entering/leaving the site to remove vegetation to avoid the spread of weeds; 3. All disturbed areas will be re-vegetated according to plans in the design; 4. All construction activities will be performed in the stream or immediate vicinity,shall be conducted in a manner to reduce potential for instream turbidity; 5. New channel design and dimensions will be implemented as defined in the design documents approved by the Technical Advisory Committee; 6. Gradual dewatering of the channel will be conducted to reduce the stranding of fish during construction. NOTE: This permit is valid for one year from the date of receipt. This project will not increase turbidity if completed according to the conditions listed in the 124 permit. Therefore,application to DEQ for a 318 authorization is not required. Impacts to the physical and biological environment from turbidity generated as a result of this project are uncertain. Therefore,the applicant must contact DEQ to determine project specific narrative conditions required to meet short-term water quality standards. X Turbidity generated from this project is expected to be short-term and have only temporary and minor impacts on the physical environment. Therefore,compliance with DEQ's short term water quality standard and conditions listed in the 124 permit are appropriate Sincerely, on Fishery Biologist C: Region 3 File SHORT-TERM WATER QUALITY STANDARD C FOR TURBIDITY RELATED TO na Department of CONSTRUCTION ACTIVITY (318 Authorization) IRONMENTAL QUALITY Dear Applicant: This 318 authorization is the result of your recent application for a 310 permit from your local Conservation District or a 124 permit from Montana Fish,Wildlife and Parks.This authorization is valid for the time frame noted on your permit.

This authorization is the result of an Operating Agreement between the Montana Department of Environmental Quality (DEQ), and Montana Fish,Wildlife and Parks (FWP). The applicant agrees to the comply with the conditions stated below,as well as other conditions listed in the 310 or 124 permit issued for this project. Signatures of the applicant and FWP are required to validate this authorization. 1.

The use of machinery in the watercourse shall be avoided unless absolutely necessary. 3. MI disturbed stream banks and adjacent areas created by the construction activity shall be protected with erosion control measures during construction. These areas shall be reclaimed with appropriate erosion control measures and revegetated to provide long-term erosion control. 4. Any excess material generated from this project must be disposed of above the ordinary high water mark,in an area not classified as a wetland,and in a position not to cause pollution of State waters. 5. Clearing of vegetation will be limited to that which is absolutely necessary for construction of the project. 6. This authorization does not authorize a point source surface water discharge. MPDES permit is required for said discharge. 7. Open cut creek crossings will not be allowed in flowing water. Stream water must be diverted around the open cut area(pump, flume etc.) 8.
