Florida’s Pollutant Trading Program
2008 Revisions to Florida Watershed Restoration Act focused on water quality credit trading. Authorized trading, but limited to pilot project in Lower St. Johns River Basin (LSJR); Authorizes trading in the LSJR pilot program under process established in adopted Basin Management Action Plan (BMAP). Required FDEP to initiate rulemaking by September 1, 2008. FDEP issued Notice of Rule Development in August 2008 and held first public workshop on November 21, 2008. 2008 Legislation provides authority for Pilot Trading Program under process established in adopted BMAP, but, OGC recommended FDEP adopt rule for Pilot. Longer term, will also need to revise rule for any expansion of program. The rule will be done in “phases” with initial rulemaking focused on pilot program. Generally speaking, FDEP has translated BMAP text into rule language to support pilot. BMAP authorizes “Formal” Trading that occurs AFTER adoption of BMAP with detailed allocations to individual sources. Trading must be implemented via permits. One of the trading parties must have an individual permit.
