Permit and Other Fees. The Secretary of Public Works shall, for a reasonable fee, not to exceed $100 if for a commercial use or $5.00 if for self-help improvement projects, issue a permit for sand mining in an authorized area upon application from any person. The application form for sand mining shall not be complicated and may be issued on a project basis, if, in the judgment of the Secretary of Public Works, the sand mining will not be detrimental to the coastal zone, provided, however, that a fee in addition to the permit fee may be charged by the Department of Public Works not to exceed $2.00 per cubic yard if the sand mining is for a commercial purpose.
