No new excavation, dredging or filling which alters the shoreline or lake bottom will be permitted on state property except dock and adjacent bulkhead construction duly permitted by the Department. Permits for such work may be issued, within the Director's or designee's discretion, on the basis of the applicant's submittal of engineering plans and specifications for such work which demonstrate that it is not adverse to the best interest of the State and upon the permit applicant's agreement to furnish a performance bond and, upon completion, a certification from his engineer that said work was performed and completed in conformance with the engineer's plans and specifications. Once completed in accordance with specifications, the permit holder shall not physically expand or in any manner alter the dimensions, form or shape of the existing facilities without a new permit being issued in accordance with this rule.
