Thank you,Nancy IhlenfeldtHabitat BiologistAK Department of Natural ResourcesOffice of Habitat Management & Permitting Fairbanks Office907-459-7287Sent: Tuesday, June 21, 2005 3:18 PMTo: Barta Carrie L MS DPW NEPA COORDINATORCc: bob_henszey@fws.govSubject: Integrated Training Area Mgmt PlanCarrie:In addition to the comments sent on June 13, 2005 regarding the abovereferenced Environmental Assessment, the ADNR, Office of HabitatManagement and Permitting (OHMP) has the following comments regardingAppendix C2 of the EA:(1) I think an introduction paragraph stating that all activitiesdescribed in this document require a permit(s) from one or more stateand/or federal agency.(2) Page C2-1 through C2-2. C2-3. Culvert Installation. Using theheadings "Non Anadromous Fish Culverts" and "Anadromous Fish Culverts"is confusing.Culverts placed for maintaining area hydrology should be called"wetland" or "drainage" culverts. Culverts placed in streams to allowfish passage are required in streams that support both anadromous andresident fish (i.e., not just streams designated as anadromous). Thewidth of the stream will designate the diameter of the culvert and if abridge would be more appropriate than a culvert(s).(3) Page C2-2 through C2-5. Dust Control. The water source should be aconsideration -- if withdrawing water from a stream, lake or pond a FishHabitat Permit as well as a Temporary Water Use Permit from the ADNR,Division of Mining, Land and Water may be required.(4) Page C2-5. Erosion and Sediment Control Structures.A. Asphalt. What would be the application of asphalt at a streamcrossing?B. Barbed Dike or Thalweg Deflector Devices. In-stream structuresshould be the last resort at solving stream bank erosion problems,especially in streams that have been designated as anadromous. Inaddition, these structures must be designed by an experiencedengineer/hydrologist. If these structures are not designed andconstructed properly, they can be destructive. What is "AlaskaStreambank Repair #27", the last sentence in the paragraph?(5) Page C2-13. I. Gabions. First paragraph, second sentence -Why/when would you want to prevent fish passage from one waterbody toanother?_____________________________________________________________________________________________Environmental AssessmentUnited States Army Alaska, Integrated Training Area Management ProgramManagement Plan E-8
Second paragraph - I do not understand what is being described, is thestructure going all the way across the stream?(6) Page C2-18. III. Outlet Protection. Are these outlets drainingdirectly into streams that support fish? If so, the design andconstruction methods need to keep that in mind.(7) Page C2-19. Q. Reinforced Concrete. The first sentence states thatreinforced concrete can be used to control erosion at streamcrossings....what is the application for this? More details would be nice.(8) Page C2-20. R. Rip Rap. Third paragraph, second sentence - whatother materials (other than riprap) and what methods can be employed onslopes steeper than 2:1 for erosion protection? Riprap structuresplaced on the bottom of a stream to create riffles and pools must bedesigned by an engineer/hydrologist who has experience with these typesof projects. If installed and/or designed improperly, these structurescan be very destructive to a stream and the existing fish habitat.(9) Page C2-21. R. Rip Rap. First bullet - "Riprap limits. The riprapshould extend for the maximum flow depth, or to a point where vegetationwill be satisfactory to control erosion." What is meant by "maximumflow depth"? Should this be "ordinary high water elevation"? Thirdbullet - "Riprap Size. The size of riprap to be installed depends onsite-specific conditions." Please add at the end of the sentence,"...(e.g., hydrology, bank steepness, cause of erosion, etc.)"Second paragraph, second sentence - Please add at the end of thesentence, "...(i.e., when water levels are at there lowest)." Thestatement, "Bypassing base flows or temporarily blocking base flows aretwo possible methods." is not really a true statement. As stated above,the OHMP prefers that this type of work be conducted when water levelsare low and the introduction of sediment can be minimized. Installingtemporary in-stream structures and/or blocking streams should be a lastoption for this type of work. And, the last sentence in this paragraphI do not believe is a true statement - it really depends on the cause oferosion and the stream type.Third paragraph, last sentence reads "Control of weed and brush growthmay be needed in some locations." It has been documented that rootstructures (e.g., grass, willows, shrubs) on and above a stream bank,especially within a riprap structure, immensely helps strengthen thestructure and bank. If there are willows growing in the riprap, Istrongly suggest not disturbing them.(10) Page C2-35. Y. Sediment Trap. Fourth paragraph - just toreiterate, even though a structure placed in a stream is "temporary" itwill still require a Fish Habitat Permit from the OHMP.(11) Page C2-36. Y. Sediment Trap. First paragraph, the third sentencereads "Fords are appropriate in steep areas subject to flashflooding..."The OHMP would include the following stipulations in a vehicle streamcrossing permit: (1) stream crossings shall be made from bank to bank ina direction substantially perpendicular to the direction of stream flow;_____________________________________________________________________________________________Environmental AssessmentUnited States Army Alaska, Integrated Training Area Management ProgramManagement Plan E-9
