135(1) “Action level” means a specified concentration of a contaminant that, if exceeded during natural attenuation with monitoring or post active remediation monitoring, may require additional site assessment or active remediation. Action levels are established during the approval process for Natural Attenuation Monitoring Plans pursuant to rule 18262-780.690, 183F.A.C., and Post Active Remediation Monitoring Plans pursuant to rule 19362-780.750, 194F.A.C. “Action levels” are not equivalent to “cleanup target levels.”
204(2) 205“Dose Additivity” is the calculated interactive effects of chemicals that share the same mechanism of toxicity. Guidance on the chemicals encompassed and methods for assessing dose additivity is provided in the “Dose Additivity” document referenced in subsection 24262-780.100(24), 243F.A.C.
244(3) “Background concentrations” means concentrations of contaminants that are naturally occurring 255or resulting from anthropogenic impacts unrelated to the discharge of pollutants or hazardous substances at a contaminated site undergoing site rehabilitation, 276in the groundwater, surface water, soil, or sediment in the vicinity of the site.

312(5) “Brownfield Site Rehabilitation Agreement” (BSRA) means an agreement entered into between the person responsible for brownfield site rehabilitation and the Department. The BSRA shall at a minimum establish the time frames, schedules, and milestones for completion of site rehabilitation tasks and submission of technical reports, and other commitments or provisions pursuant to section 366376.80(5), F.S., 368and this chapter.
371(6) “BSRA” means Brownfield Site Rehabilitation Agreement.
378(7) “CAD” means cleanup agreement document.
384(8) “Cleanup agreement document” (CAD) means any order or agreement issued to or entered into by the Department with a Person Responsible for Site Rehabilitation, including a voluntary cleanup agreement, permit, consent order, final order, or final judgment.

468(9) “Conceptual Site Model” (CSM) means a written and/or graphic representation of the physical, chemical and biological processes that affect the transport, migration and actual or potential exposure to contamination in all affected media to human and ecological receptors. The CSM is used to develop and refine the extent of site assessment, support remedial alternative, mitigation and cleanup technology evaluations, and support risk management decisions. The CSM is an optional submittal and may be prepared or updated at any time during site rehabilitation as new or revised information becomes available. The CSM may be a single document or combined with any other document.
571(10) “Contaminated” or “contamination” means the presence of free product or any contaminant in surface water, groundwater, soil, sediment, or upon the land, in concentrations that exceed the applicable CTLs specified in chapter 62-777, F.A.C., or water quality standards in chapter 62-302 or 62-520, F.A.C., or in concentrations that may result in contaminated sediment. 625At sites where alternative CTLs have been developed solely based upon intrinsic chemical properties that do not vary under different exposure scenarios (e.g., toxicity) or based upon a risk assessment where the exposure parameters have been demonstrated to be applicable throughout the study area, then such alternative CTLs are the applicable CTLs for evaluting “contaminated” or “contamination” and would supersede the CTLs specified in chapter 62-777, F.A.C. However, alternative CTLs can not be substituted for water quality standards in chapter 62-302 or 62-520, F.A.C. 709This definition is solely for use within chapter 62-780, F.A.C., and pursuant to section 723376.30701(1)(a), F.S., 725shall not be used to establish legal responsibility for conducting site rehabilitation.
737(11) “Contaminated sediment” means sediment that is contaminated as determined by the concentrations of the contaminants, actual circumstances of exposure, biological diversity studies, toxicity testing, or other evidence of harmful effects, as applicable. [Refer to the sediment guidelines referenced in subsections 77862-780.100(1) 779and (6), F.A.C., for guidance on the evaluation of contaminant concentrations, sediment quality conditions, and testing methods.]

Readings shall be obtained at the site on an organic vapor analysis instrument with a flame ionization detector in the survey mode upon sampling the headspace in half-filled, 8-ounce or 16-ounce jars. Each soil sample shall be split into two jars, the two subsamples shall be brought to a temperature of between 20° C. (68° F.) and 32° C. (90° F.), and the readings shall be obtained 5 to 30 minutes thereafter. One of the readings shall be obtained with the use of an activated charcoal filter unless the unfiltered reading is nondetect. The total corrected hydrocarbon measurement shall be determined by subtracting the filtered reading from the unfiltered reading. Instruments with a photo ionization detector may be used, but shall not be used in situations where humidity will interfere with the instruments’ sensitivity (including periods of rain, measuring wet or moist soil). If an instrument with a photo ionization detector is used, a filtered reading is not warranted and therefore sample splitting is not necessary.
