NATIONAL FOEEST MANUAL. 51 



Whenever the time prescribed by the State statutes within which 

 construction must begin in order to maintain water rights is insuf- 

 ficient to enable the applicant to prepare a final application before 

 beginning construction, a clause may be inserted in the preliminary 

 permit allowing construction to proceed to an extent sufficient to per- 

 mit compliance with the State law. Only in exceptional cases will 

 a clause be inserted allowing construction in advance of final applica- 

 tion and permit for any other reason than to permit compliance with 

 the State law, and when inserted for any other reason the necessity 

 for it must be fully explained in the recommendation of the district 

 forester. 



No extension will be granted except upon the written approval of 

 the Secretary of Agriculture after a satisfactory showing by the per- 

 mittee of the reasons for such extension, and alter a report has been 

 submitted by the district forester. 



To prevent speculative holding of sites under preliminary permits 

 and to secure the presentation of the final application within the time 

 named in the preliminary permit, an annual charge will be made dur- 

 ing the term of the preliminary permit. The charge will be calcu- 

 lated on the basis of the estimated rental capacity of the power site 

 to be occupied and at the rates prescribed in Regulation L-8. If the 

 final application is filed in accordance with the terms of the prelimi- 

 nary permit, and if construction is completed and operation is begun 

 in accordance with the terms of the final permit, the payments made 

 under the preliminary permit will be credited upon payments due or 

 to become due after the beginning of operation under the final permit. 



The lines shown on the maps accompanying the final application 

 will not be required to follow without change the lines as shown on 

 the map accompanying the preliminary application, and the position 

 and arrangement of conduits and power houses as shown upon the 

 map accompanying the preliminary application may be changed, if 

 the detailed surveys preceding the final application show such change 

 to be desirable ; but priority from the date of filing of the preliminary 

 application will be allowed for only so much of the projects shown in 

 the application for final power permit as is within the approximate 

 limits of diversion and discharge as shown in the application for the 

 preliminary power permit. (Reg. L-3.) 



Upon the failure of the permittee to comply with the terms of a 

 preliminary permit the district forester will write him a letter call- 

 ing his attention to the violation of the terms and notify him that by 

 reason thereof the permit expired on a given date and the priority 

 acquired thereby was lost. Copies of this letter of notification should 

 be sent to the supervisor and to the Forester. If a preliminary permit 

 is thus terminated, no other application for a permit either preliminary 

 or final covering the same or adjacent lands will be received from the 

 same applicant for a period of one year subsequent to the termination 

 of the preliminary permit. 



The date upon which priority of application is established shall be 

 the date of the filing in the office of the district forester of the last 

 map or paper necessary to constitute a complete application as 

 required by Regulation L-10. The date and hour of the receipt 

 of a preliminary application will be inserted in the space provided 

 on the form (Form 58a) and will be certified by the signature 

 of the district forester. Upon the receipt of preliminary appli-
