Section 40E-63.437 - Alternative BMP PlansApplicants who propose to satisfy the water quality requirements of this part of Chapter 40E-63, F.A.C., by employing a BMP Plan other than those described in subsections 40E-63.435(1) and (2), F.A.C., may seek approval for an equivalent alternative through the District permit process. The applicant shall provide reasonable assurance, through the information required below and the requirements indicated in subsections 40E-63.435(3), (4), (5) and (6), F.A.C., that the alternative contains the equivalent or greater phosphorus reduction effectiveness of a 35-point BMP Plan. A BMP Plan shall take into account site-specific conditions, potential phosphorus sources, primary phosphorus species, and transport mechanisms; and ensure that a thorough approach to implementation and maintenance will be implemented. In order to seek approval of an alternative BMP Plan, applicants must submit the information specified for the applicable alternative as part of the permit application process.
(1) Alternative Type BMP. If an applicant proposes BMPs not listed in Appendix B1 (incorporated by reference in subsection 40E-63.435(1), F.A.C.), the application shall also include the following information for District approval: (a) A description of the best management practice rationale for the BMP selected;(b) A detailed explanation of the proposed BMP;(c) A schedule for implementation of the BMP;(d) Sample documentation of the BMP implementation, how the BMP will be verified;(e) Technical basis for the reduction effectiveness of the proposed BMP. The applicant shall be required to demonstrate effectiveness through a proposed monitoring program or through representative technical references including modeling results approved by the District. If approved, the District will determine the appropriate BMP equivalent point credit consistent with Appendix B1 (incorporated by reference in subsection 40E-63.435(1), F.A.C.).(2) Alternative BMP Points per Category. If the BMP Plan does not meet the minimum number of equivalent points per BMP category as required in subsection 40E-63.435(2), F.A.C., the application shall include a site assessment demonstrating that an alternative BMP Plan will provide an equivalent or greater reduction effectiveness than using the standard approach. The site assessment shall evaluate phosphorus imports and transport in discharges; current BMPs and implementation methods; other activities for which BMPs are not being implemented and representative water quality and soil data. Water quality data that can be used for the assessment include those available from the District sub-basin or synoptic (grab) monitoring programs, or properly collected grab samples using field kits of adequate precision by the applicant.
(3) Alternative BMP Demonstration Project. If a demonstration project is proposed to meet the BMP implementation requirements of subsection 40E-63.435(1) or (2), F.A.C., a proposed project scope of work shall be submitted for District review and approval based on the following criteria:(a) The scope of eligible projects shall include, at a minimum, the demonstration or research hypothesis, a description of implementation, the technical basis and scientific methods that will be employed, the performance indicators that will be measured such as water quality, water quantity, soil testing, or as applicable, the progress and final reports that will be produced to verify progress and results, and a schedule that details the beginning date, critical milestones and ending date of the project.(b) The 35 BMP equivalent point requirement shall be met in the permit basin where the project is proposed. The proposed demonstration shall account for no more than 20 BMP equivalent points as approved by the District. The remaining 15 BMP equivalent points shall include 10 BMP equivalent points in the nutrient control practices category and 5 BMP equivalent points in the water management practices category.(c) The proposed BMP equivalent points for the demonstration project will only be considered for the period of project implementation, the permit basin where the project is located, and for the crops or land uses to which the project applies.(d) BMP equivalent points shall be initially determined by the District prior to issuance of a permit based on the BMP equivalent points established in Appendix B1 (incorporated by reference in subsection 40E-63.435(1), F.A.C.). Additional BMP equivalent points will be approved by the District, if the applicant provides reasonable assurance through plans, test results, water quality data or other information, that the BMP project will demonstrate improvement in phosphorus removal efficiency in comparison to standard BMP implementation methods.(e) Once the demonstration project is complete and a final report is submitted in accordance with the approved scope, the permittee shall submit a Letter Modification application requesting that the approved BMP Plan be modified to incorporate the BMP or water quality improvement activity if the District determines that they were successfully developed under the project. The application shall include the information described under Rules 40E-63.430, 40E-63.435 and 40E-63.437, F.A.C., as applicable, and shall describe how the report recommendations for BMP implementation will apply to the applicable crops or land uses for District review. The District shall review the BMP equivalent points initially assigned and will adjust them based on the reported phosphorus reduction levels and approved methods for implementation of the proposed BMP or water quality improvement activity. If the permittee decides that the BMP resulting from the demonstration project is not to be proposed for continued implementation, the permittee is required to submit a permit modification proposing a BMP Plan, as described in Rule 40E-63.435 or 40E-63.437, F.A.C., as applicable. The application for modification of the approved BMP Plan shall be submitted no later than 30 days after the project completion date pursuant to the District-approved scope.Fla. Admin. Code Ann.
