This will give you the <br />required design information you're looking for... <br />See this for our National BMPs for forest activities ... pg 117 has them for stream crossings: <br />http: // .fs.fed.us /biology/ resources / pubs / watershed /FS_National_Core_BMPs Apri12012.pdf <br />Here's a link to our "Watershed Conservation Practices Handbook." See the "2509.25_10.doc" for design <br />criteria that we would look for ... some of them may or may not be applicable to mine related projects. <br />http://www.fs.fed.us/cgi-bin/Directives/get—dirs/fsh?2509.25 <br />Lastly, although it is written for Oil and Gas activities, the Gold Book has good descriptions of BMPs and <br />design criteria for roads: <br />http: // . bim. govl wo lstlenlproglenergyloil_and_gasl best_ management _practiceslgold_book.htmi <br />Ryan <br />https: / /mail.g oog le.conVmai I /u /0 / ?ui =2 &i Ire29129fcb5 &viev�-- pt &search =i nbox&th= 13fOa2e5O7fb5655 2/3 <br />
