   1. (a) The permittee shall submit the information as outlined in Department DEP Form 62-660.900(6), Notification Form to Use the General Permit for Sand and Limestone Mines, effective, February 3, 2015.

   2. (b) A Best Management Practices (BMP) Plan shall be developed and implemented for the facility. The BMP Plan shall include elements designed to prevent or minimize the potential for the release of pollution to waters of the state from ancillary activities. Ancillary activities may include material storage areas, plant site runoff, in-plant transfer, process and material handling areas, and loading and unloading operations through plant site runoff, spillage or leaks, or drainage from raw material storage. The BMP Plan shall be subject to the following requirements:

      1. The applicant shall maintain the BMP Plan at the facility and shall make the plan available to the Department upon request.

      2. The BMP Plan shall be maintained in written form, and shall include any necessary site plans, drawings, or maps. The BMP Plan shall be prepared and certified by a professional engineer registered in the State of Florida and shall be reviewed by the facility staff.

      3. The BMP Plan shall identify areas, systems or components of the facility that have a potential for causing a release of pollution to waters of the state, due to equipment failure, improper operation, or natural phenomena such as extreme rain or winds.

      4. The plan shall include a prediction of the direction, rate of flow, and total quantity of pollution which could be discharged from the facility as a result of equipment failure, improper operation, or natural phenomena such as extreme rain or winds.

      5. The BMP Plan shall establish specific preventive and remedial procedures to prevent pollution from reaching waters of the state in amounts which will cause a violation of water quality standards.

      6. The BMP Plan shall be revised as necessary whenever there is a change at the facility which increases the potential for the release of pollution to waters of the state.

      7. The facility shall be reasonably maintained to prevent entry of unauthorized personnel.

      8. The facility is not required to prepare a separate BMP if all of the requirements of the BMP Plan are addressed within a Stormwater Pollution Prevention Plan (SWPPP) prepared under subsection 62-621.300(5), F.A.C.

6. (6) Design Requirements. A professional engineer registered in the State of Florida shall certify the following:

   1. (a) All earthen dams storing process wastewater and runoff above grade shall be constructed and maintained in accordance with good engineering practices.
   2. (b) The sand or limestone mine is designed to recycle process wastewater and contain process wastewater and runoff from storm events up to a 25-year, 24-hour storm or equivalent event.

7. (7) Operational Requirements.

   1. (a) There shall be no discharge from storage ponds except as a result of storms exceeding a 25-year, 24-hour storm or equivalent event.
   2. (b) No chemicals, except water conditioners, pH adjusters and chemicals which have been demonstrated as to not adversely affect human health or aquatic life shall be added to the process water used for transporting, washing or processing of the sand or limestone. Records of all chemicals used (including dosage rates) by the facility must be kept and made available for inspection to the Department upon request.
