(511.49 Conservation plan revisions, 



(a) A person may request assistance from SCS at any time in 

 revising an approved conservation plan. SCS will provide assistance 

 in revising the plan consistent with local priorities. 



(b) A conservation plan revision occurs when an existing plan is 

 changed because of a chzmge in farm size, farm enterprise, 

 conservation system, farm owner, or farm operator. A revised plan 

 normally results in a new conservation plem docxoment. 



(c) A person may revise his/her conservation plan to provide for 

 the ACS level of treatment when the original plan provided for a BCS 

 or RMS level of treatment, as long as the plan revision is not done 

 as part of a status review. All plan revisions and practice schedule 

 changes should plan for achieving some erosion reduction in each 

 calendar year so that the conservation system will be fully in use by 

 Jemuary 1, 1995. This requirement is particularly intended to 

 accommodate changes in ownership, farm enterprise, and/or the 

 substitution of management practices for structural practices. 



(d) Revised conservation plans will be in conformance with the 

 FOTG that is in effect at the time the revision is made, and will ^ 

 need to be approved by the conservation district in order to replace i 

 an existing approved conservation plan. 



(e) All persons will be required to be using an approved 

 conservation system by January 1, 1995 on all highly erodible fields 

 that are used to produce agricultural commodities, regardless of the 

 number of conservation plan revisions. 



(f) Revisions of conservation plans for sodbusted fields must 

 provide for continued use of an approved conservation system on the 

 sodbusted fields, even if the sodbusted field was recently acquired 

 by the person.
