Whether Respondents have violated Chapter 403, Florida Statutes by dredge and fill activities at Sampson Lake, Bradford County, Florida, and should therefore be subject to corrective action and costs, as set forth in Notice of Violation and Orders for Corrective Action, dated March 4, 1982. This case arises from Petitioner's filing of a Notice of Violation and Orders for Corrective Action against Respondent Dudley P. Hardy on March 4, 1982, alleging that he conducted dredge and fill activities on property which he owned adjacent to Sampson Lake without obtaining a departmental permit for such activities. The notice further alleged that such activities created a stationary installation reasonably expected to be a source of pollution, and sought to have the Respondent take corrective action by restoring the affected area, and also to nay investigative costs, pursuant to Chapter 403, Florida Statutes. Respondent Hardy responded to the Notice of Violation and therein requested an informal administrative hearing pursuant to Section 120.57(2), Florida Statutes. He also averred that he only owned a one-half interest in the subject property, and that the other one-half interest was owned by J. D. Odom, Jr. and Vernie Phillips Odom, his wife. Based upon Petitioner's request, a formal hearing under Section 120.57(1), Florida Statutes, was scheduled for July 14-15, 1982, but pursuant to Petitioner's Motion for Continuance, the hearing was rescheduled for August 12- 13, 1982, by Order dated May 24, 1982. Petitioner thereafter amended its notice of violation to include J. D. Odom, Jr. and Vernie Phillips Odom as Respondents in the proceeding as indispensable parties. By Order dated July 7, 1982, Petitioner's Motion for Leave to Amend was granted. By Order of Consolidation dated April 28, 1982, this case was consolidated with five other cases involving similar activities at Sampson Lake. (DOAH Cases Nos. 82-907and 02-909 - 82-912) However, prior to the scheduled hearing, counsel for Petitioner advised the Hearing Officer that the other cases had been resolved by consent orders. At the hearing, Respondent J. D. Odom, Jr. appeared without counsel and was advised of his rights in a Chapter 120 administrative proceeding. He acknowledged his understanding of such rights and elected to proceed without counsel. Petitioner presented the testimony of three witnesses and submitted ten exhibits. Respondent testified in his own behalf and submitted two exhibits. After the conclusion of the hearing, Respondent J. Odom submitted a letter to the Hearing Officer, dated August 17, 1982, which enclosed a copy of a survey which had been previously received in evidence as Petitioner's Exhibit 1, and photographs which had not been received in evidence at the hearing. Petitioner filed a Motion to Strike these matters, and the motion is hereby partially granted. The additional photographs presented by Respondent can not be taken into consideration in this Recommended Order because they were not admitted in evidence at the hearing. Petitioner's post-hearing Proposed Findings of Fact, Conclusions of Law, and Proposed Recommended Order has been fully considered, and those portions not adopted herein are deemed either unnecessary or irrelevant, or unsupported in law or fact. In like manner, the statements made by Respondent Odom in his post-hearing letter that are unrelated to the photographs have been fully considered.Respondents dug unpermitted canal on Class III waters of state.
