GUIDELINES FOR NOTICES <br />Surface Disturbance <br />1. Any activity that results in excavation or in compaction, powdering, or erosion of the <br />original ground surface is considered disturbance and must be reclaimed. This may <br />include the blading or rutting of existing roads, the development of a rutted surface during <br />cross country travel, and drilling or trenching. You must contact this office if you expect <br />to exceed a total disturbance of five acres; submittal of a Plan of Operations may be <br />necessary. <br />2. The operator should document their portion of the disturbance in areas where other <br />operators have or will be conducting operations. This should be done by submitting to <br />BLM a map showing the existing disturbance and the proposed new disturbance and <br />.indicating the time periods (if known) during which past disturbance occurred. <br />Reclamation of disturbance done under this notice is the responsibility of the claimant <br />and includes liability for reclamation not satisfactorily completed by the operator. <br />3. Projects should avoid unnecessary impacts by planning reclamation activities to occur <br />within a reasonable time after exploration is completed. Sites should be reclaimed as soon <br />as possible to minimize impacts to other resources. Open pits should be maintained in a <br />manner to avoid injury to the public, livestock, and wildlife. <br />4. Access roads, pads, and other sites should be designed, constructed, maintained, and/or <br />used in a manner that is safe, controls drainage and erosion, minimizes impacts to <br />resources, and facilitates successful reclamation. Locations and design should consider <br />slopes, soil types, drainage etc. Overland travel should be proposed where conditions <br />will not result in surface disturbance; e.g. dry or frozen soil conditions, low level of <br />traffic, and flat terrain. Surface materials should be adequate to accommodate proposed <br />activities and seasons of use. Activities should not result in ruts of 4 inches or more, or <br />encroach or intercept drainage channels. Road construction should not block drainages. <br />Designs and construction should meet goals and standards as described in the BLM 9113 <br />Manual Section on Roads. <br />5. Disturbance to natural drainages including blading or filling should be avoided. Where a <br />dry wash offers the only feasible access to a site, no blading of the wash should occur. <br />No disturbance should occur within 100 ft. of active drainages, springs, and seeps. <br />Drainage crossings should neither obstruct the channel nor result in increased erosion or <br />sedimentation. <br />Reclamation <br />6. A minimum of six inches of surface soils (growth medium) should be stockpiled prior to <br />surface disturbing activities (unless waived by the BLM). Earthwork should blend <br />disturbed areas back into pre-disturbance topography, e.g. reclamation of road cuts into <br />hill sides should involve pulling excavated material back up into the road cuts so as to <br />closely approximate the original hillside. Seed beds should be rough. Growth medium
