(1) Natural Attenuation Monitoring and long-term natural attenuation monitoring are allowable strategies for site rehabilitation depending on the individual site characteristics, provided human health, public safety, and the environment are protected. The individual site characteristics may include the current and projected use of the affected groundwater and surface water in the vicinity of the site, the current and projected land use of the area affected by the contamination, the exposed population, the location of the plume, the degree and extent of contamination, the rate of migration of the plume, the apparent or potential rate of degradation of contaminants through natural attenuation, and the potential for further migration in relation to the site’s property boundary. Fate and transport models as defined in Fl. Admin. Code R. 62-780.610, may be utilized to support the appropriateness of natural attenuation monitoring. Natural attenuation monitoring is allowable provided the following criteria are met:
(a) Free product is not present or free product removal is not technologically feasible and no fire or explosive hazard exists as a result of a release of non-aqueous phase liquids;
(b) Contaminated soil is not present in the unsaturated zone, except that applicable leachability-based soil CTLs may be exceeded if it is demonstrated to the Department that the soil does not constitute a continuing source of contamination to the groundwater at concentrations that pose a threat to human health, public safety, and the environment, and it is demonstrated that the rate of natural attenuation of contaminants in the groundwater exceeds the rate at which contaminants are leaching from the soil. The determination shall be based upon individual site characteristics and demonstrated by USEPA Test Method 1312 (SPLP), or USEPA Test Method 1311 (TCLP) if the contamination is derived from used oil or similar petroleum products, followed by the appropriate analyses of the leachate, and based upon groundwater modeling, site stratigraphy, or site assessment results;
(c) Contaminants present in the groundwater above background concentrations or applicable CTLs are not migrating beyond the temporary point of compliance or migrating vertically, which may contaminate other aquifers or surface water resources or result in increased site rehabilitation time;
(d) The physical, chemical or biological characteristics of each contaminant and its transformation product(s) are conducive to natural attenuation;
(e) The available data show an overall decrease in the contamination; and,
(f) One of the following is met:
1. The site is anticipated to meet the applicable No Further Action criteria of Fl. Admin. Code R. 62-780.680, as a result of natural attenuation, the background concentrations or the applicable CTLs are not exceeded at the temporary point of compliance as established pursuant to subsection 62-780.690(2) or 62-780.690(3), F.A.C., and contaminant concentrations do not exceed the criteria specified in chapter 62-777, F.A.C., Table V, or
2. If the criteria of subFl. Admin. Code R. 62-780.690(1)(f)1., are not met, the appropriateness of natural attenuation monitoring may be demonstrated by the following:
a. A technical evaluation of groundwater and soil characteristics, chemistry, and biological activity that verifies that the contaminants have the capacity to degrade under the site-specific conditions. A listing of the site-specific conditions and geochemical parameters, as applicable, is provided in chapter 62-777, F.A.C., Table IV,
b. A scientific evaluation (historical data or modeling results, as appropriate; the model used shall be demonstrated to be appropriate for the site conditions) of the plume migration in relation to the temporary point of compliance as established pursuant to subsection 62-780.690(2) or 62-780.690(3), F.A.C., an estimation of expected annual reductions in contaminant concentrations in monitoring wells, and an estimation of the time required to meet the applicable No Further Action criteria of Fl. Admin. Code R. 62-780.680 Available technical information (including historical water quality data) shall be used for model calibration; and,
c. A life-cycle cost analysis of remedial alternatives.
(2) Provided human health, public safety, and the environment are protected, the point of compliance may be temporarily moved from the source of the contamination.
(a) The location of the temporary point of compliance shall be based on the individual site characteristics listed in subsection 62-780.690(1), F.A.C.
(b) The point of compliance may be temporarily moved to the property boundary, or to the edge of the plume when the plume is within the property boundary, while cleanup, including cleanup through natural attenuation processes in conjunction with appropriate monitoring, is proceeding.
(c) The temporary point of compliance may extend beyond the property boundary when accompanied by monitoring, if such extension is needed to facilitate monitoring of natural attenuation or to address the current conditions of the plume, provided human health, public safety, and the environment are protected. If the point of compliance is proposed to be temporarily extended beyond the property boundary, it cannot be extended further than the lateral extent of the plume at the time of execution of a CAD, if known, or the lateral extent of the plume as defined at the time of the approved site assessment. Prior to the Department authorizing a temporary extension of the point of compliance beyond the property boundary, the PRSR shall provide notice and an opportunity to comment pursuant to subsection 62-780.220(3), F.A.C.
(d) Pursuant to subsection 62-780.220(4), F.A.C., additional notice concerning the status of the natural attenuation processes shall be similarly provided every five years to persons receiving notice pursuant to Fl. Admin. Code R. 62-780.690(2)(c)
(3) Where surface water is or may be exposed to contaminated groundwater (based on monitoring well data, groundwater flow rate and direction, or fate and transport modeling), the point of measuring compliance with the surface water standards shall be in the groundwater from the landward side immediately adjacent to the surface water body. For cleanups being conducted pursuant to Florida Statutes § 376.30701(2), (including petroleum contamination sites being addressed pursuant to Florida Statutes § 376.3071, that are not eligible for state-funded site rehabilitation, if the PRSR elects) or Florida Statutes § 376.81(1), such measurement is not necessary if it has been demonstrated, based on site assessment data provided in accordance with Fl. Admin. Code R. 62-780.600, that the contaminants do not cause or contribute to the exceedance of applicable surface water quality criteria.
(4) If the criteria of subsection 62-780.690(1), F.A.C., are met, a Natural Attenuation with Monitoring Plan, prepared pursuant to subsection 62-780.690(8), F.A.C., may be submitted. Unless the Natural Attenuation with Monitoring Plan is included in a Site Assessment Report pursuant to subFl. Admin. Code R. 62-780.600(8)(b)2., or in a Risk Assessment Report pursuant to Fl. Admin. Code R. 62-780.650(4)(b), the PRSR shall submit to the Department for review an electronic or paper copy of the Natural Attenuation Monitoring Plan.
(5) The Department shall:
(a) Provide the PRSR with written approval of the Natural Attenuation Monitoring Plan, or
(b) Notify the PRSR in writing, stating the reason(s) why the Natural Attenuation Monitoring Plan does not contain information adequate to support the conclusion that the applicable Natural Attenuation Monitoring criteria of Fl. Admin. Code R. 62-780.690, have been met.
(6) If the Natural Attenuation Monitoring Plan is incomplete in any respect, or is insufficient to satisfy the criteria of subsection 62-780.690(1), F.A.C., the Department shall inform the PRSR pursuant to Fl. Admin. Code R. 62-780.690(5)(b), and the PRSR shall submit to the Department for review an electronic or paper copy of a revised Natural Attenuation Monitoring Plan that addresses the deficiencies within 30 days after receipt of the notice. If the deficiencies are not timely corrected, or cannot be corrected, the PRSR shall, as appropriate, continue the implementation of the approved Remedial Action Plan or submit to the Department for review an electronic or paper copy of a Remedial Action Plan pursuant to Fl. Admin. Code R. 62-780.700, within 60 days after receipt of the notice.
(7) If the Natural Attenuation Monitoring Plan meets the criteria of subsection 62-780.690(1), F.A.C., a Natural Attenuation Monitoring Plan approval shall be issued. The objective of the monitoring program shall be to meet the applicable No Further Action criteria of Fl. Admin. Code R. 62-780.680
(8) The monitoring program shall be performed as specified in the Natural Attenuation Monitoring Plan approval, as follows:
(a) A minimum of two monitoring wells is required:
1. At least one well shall be located at the downgradient edge of the plume; and,
