Florida Geological Survey statement of policy outlining rules and regulations to be observed in performing offshore geological and/or geophysical work was prepared by the State Board of Conservation (Babcock, 1966). These covered "submerged lands, other than inland waters of Florida and applicable to federal lands seaward of Florida's boundary." The rules were supposedly "pursuant to authorization of the Department of the Interior of the United States dated April 3, 1965, and published in the federal register (Federal Register Document 56-2450, Volume 21, No. 64)." Approximately 100 offshore geophysical permits were issued. In the early 1970's, it was determined that there was no statutory authority to issue these permits and geophysical permitting was discontinued (David Curry, Florida Geological Survey Oil and Gas Section Administrator, personal communication, 1989). These rules expressed concern for natural resources other than oil and gas, primarily for commercial fisheries; thus, the concern was again prompted by economics. They included; however, a brief reference which indicates an aesthetic or environmental concern (Babcock, 1966): "All operators conducting seismic operations shall use reasonable precaution in accordance with approved and accepted methods to prevent destruction of, or injury to, fish, oyster, shrimp and other aquatic life, wildlife, or other natural resources." PHASE IIl: PETROLEUM POLICY DEVELOPMENT IN RESPONSE TO ENVIRONMENTAL CONCERN South Florida Development History The minimal legislative activity and apparent lack of environmental concern between the time of the passage of the conservation law and the early 1970's may have been partly due to the slow development and limited success in south Florida following the opening of the Sunniland field. During the years between Sunniland field discovery (1943) and the first rule revision to include extensive environmental concerns (1972), only 92 exploratory wells were drilled in south Florida. The Sunniland discovery was not followed by the usually rapid successes seen when new production areas are opened. Forty Mile Bend field was discovered in 1954, but showed disappointing production from only two wells and was abandoned in 1955 (Gunter, 1955 and 1956). The second really successful oil field was not discovered until 1964, 21 years after the Sunniland discovery. This was the Sunoco Felda field (Babcock, 1966). Discoveries of West Felda field in 1966 (Babcock, 1968), Lake Trafford field in 1969 (Applegate and Lloyd, 1985), and Bear Island in 1972 (Applegate and Lloyd, 1985) followed. Policy Development In Response to South Florida's Sensitive Environments The rule revision of 1972 included the first statutory evidence of serious environmental concerns and the first mention of concern for onshore native and sensitive environmental resources. These rules incorporated the concerns that developed through the years with the recognition of the importance of wetland environments, especially as it related to oil exploration and development in south Florida. South Florida oil production is partially within the Big Cypress Swamp and is adjacent to the Everglades (Figure 1). The wetlands of these areas provide important feeding, nesting, and wintering grounds for migrating and several endangered and threatened species. are dependent upon the wetland ecosystem for subsistence (Big Cypress Area Management Task Force, 1984). The Big Cypress Swamp Advisory Committee was created by the Governor and Cabinet in 1971 in response to pressures exerted on the Big Cypress ecosystem by many external factors, not
