62-302.530: Table: Surface Water Quality Criteria
The Department of Environmental Protection (Department) gives notice of its intent to issue a variance (175252-005-EV) to Rinker Materials of Florida, 1501 Belvedere Road, West Palm Beach, Florida 33406, under Sections 373.414(17) and 403.201(1)(a), Florida Statutes, (F.S.), from the provisions of subsection 62-302.530(31), Florida Administrative Code (F.A.C.), which provides minimum standards for dissolved oxygen levels in surface waters. This variance will apply to dissolved oxygen levels in the lower layers of all reclaimed lakes at the completion of mining proposed in Environmental Resource Permit modification application No. 175252-004.
On November 17, 2005, Rinker Materials of Florida, Inc., applied for a permit modification to permit No. 175252-003 for the SCL Quarry in Miami-Dade County, a limestone mining operation with a 1,071.65-acre project area. The modification will add an additional 57.69 acres to the 325.24 acre surface water management system currently permitted for mining. During mining, stormwater within the expanded mining area will be contained within the mine pits by using a system of berms. At the completion of mining, the reclaimed lakes will be re-connected with state waters by the removal of all upland berms, and the water quality standards listed in Rule 62-302.530, F.A.C. will apply to all surface waters within the mine. The project area will require a variance from the established water quality standard for dissolved oxygen in the lower layers of all reclaimed lakes (hypolimnion) within the project boundary, since dissolved oxygen at depths may not meet the minimum required by subsection 62-302.530(31), F.A.C. The dissolved oxygen levels in the hypolimnion are expected to drop below the mandatory minimum of 5.0 mg/l at times. Stratification and the associated reduction of dissolved oxygen in the hypolimnion are natural phenomena in deep-water bodies, especially during warmer parts of the year. This was anticipated by the Florida Legislature in Section 373.414(6)(a), F.S., which states that “[w]here such mining activities otherwise meet the permitting criteria contained in this section, such activities may be eligible for a variance from the established water quality standard for dissolved oxygen within the lower layers of the reclaimed pit.” On April 7, 2008, Rinker Materials of Florida, Inc., submitted a petition for a variance, under Sections 373.414(17) and 403.201(1)(a), F.S., from the provisions of subsection 62‑302.530(31), F.A.C., which provides minimum standards for dissolved oxygen levels in surface waters.
Low dissolved oxygen levels in the hypolimnion of the lakes are not expected to result in any adverse on-site or off-site impacts. Oxygen levels in the upper layers of the lakes are expected to meet the requirements of Rule 62-302.530, F.A.C., and be adequate to support healthy fish populations during warm months when lake water stratification occurs. It is not expected that the low dissolved oxygen water from the hypoliminion will be exchanged with off-site waters. The Department considered requiring a berm to sever the hydrologic connection between the reclaimed lakes and adjacent waters, alleviating the need to meet water quality standards within the lakes. This approach was rejected in favor of a variance for three reasons. Construction of a berm would provide no environmental benefit, would require the filling of wetland areas, and may reduce the habitat value of the area by restricting the movement of water, nutrients, and fish and wildlife between the lakes and the surrounding habitat. In addition, berms would provide potential vehicle and pedestrian access to the area, which may encourage dumping and other activities harmful to the habitat value and water quality of the lakes and surrounding areas.
There is no practicable means known or available to prevent the low dissolved oxygen levels at depth within the mining lakes. Therefore, the Department intends to issue a variance in conjunction with this permit, pursuant to Section 403.201(1)(a), F.S., for dissolved oxygen in the lower layers of the reclaimed lakes.
Under this intent to issue, this variance is hereby granted subject to the applicant’s compliance with any requirement in this intent to publish notice of this intent in a newspaper of general circulation and to provide proof of such publication in accordance with Section 50.051, Florida Statutes. This action is final and effective on the date filed with the Clerk of the Department unless a sufficient petition for an administrative hearing is timely filed under Sections 120.569 and 120.57, Florida Statutes as provided below. If a sufficient petition for an administrative hearing is timely filed, this intent to issue automatically becomes only proposed agency action on the application, subject to the result of the administrative review process. Therefore, on the filing of a timely and sufficient petition, this action will not be final and effective until further order of the Department. When proof of publication is provided, if required by this intent, and if a sufficient petition is not timely filed, the variance will be issued as a ministerial action. Because an administrative hearing may result in the reversal or substantial modification of this action, the applicant is advised not to commence construction or other activities until the deadlines noted below for filing a petition for an administrative hearing or request for an extension of time have expired and until the variance has been executed and delivered. Mediation is not available.
A person whose substantial interests are affected by the Department’s action may petition for an administrative proceeding (hearing) under Sections 120.569 and 120.57, Florida Statutes. The petition must contain the information set forth below and must be filed (received by the clerk) in the Office of General Counsel of the Department at 3900 Commonwealth Boulevard, Mail Station 35, Tallahassee, Florida 32399-3000.
Under subsection 62-110.106(4), Florida Administrative Code, a person whose substantial interests are affected by the Department’s action may also request an extension of time to file a petition for an administrative hearing. The Department may, for good cause shown, grant the request for an extension of time. Requests for extension of time must be filed with the Office of General Counsel of the Department at 3900 Commonwealth Boulevard, Mail Station 35, Tallahassee, Florida 32399-3000, before the applicable deadline. A timely request for extension of time shall toll the running of the time period for filing a petition until the request is acted upon. If a request is filed late, the Department may still grant it upon a motion by the requesting party showing that the failure to file a request for an extension of time before the deadline was the result of excusable neglect.
If a timely and sufficient petition for an administrative hearing is filed, other persons whose substantial interests will be affected by the outcome of the administrative process have the right to petition to intervene in the proceeding. Intervention will be permitted only at the discretion of the presiding officer upon the filing of a motion in compliance with Rule 28-106.205, Florida Administrative Code.
In accordance with Sections 373.414(17) and 403.201, Florida Statutes, petitions for an administrative hearing by the applicant must be filed within 14 days of receipt of this written notice. Petitions filed by any persons other than the applicant, and other than those entitled to written notice under Section 120.60(3), Florida Statutes, must be filed within 14 days of publication of the notice or within 14 days of receipt of the written notice, whichever occurs first. Under Section 120.60(3), Florida Statutes, however, any person who has asked the Department for notice of agency action may file a petition within 14 days of receipt of such notice, regardless of the date of publication.
The petitioner shall mail a copy of the petition to the applicant at the address indicated above at the time of filing. The failure of any person to file a petition for an administrative hearing within the appropriate time period shall constitute a waiver of that person’s right to request an administrative determination (hearing) under Sections 120.569 and 120.57, Florida Statutes.
A petition that disputes the material facts on which the Department’s action is based must contain the following information:
(a) The name and address of each agency affected and each agency’s file or identification number, if known;
(b) The name, address, and telephone number of the petitioner; the name, address, and telephone number of the petitioner’s representative, if any, which shall be the address for service purposes during the course of the proceeding; and an explanation of how the petitioner’s substantial interests are or will be affected by the agency determination;
(c) A statement of when and how the petitioner received notice of the agency decision;
(d) A statement of all disputed issues of material fact. If there are none, the petition must so indicate;
(e) A concise statement of the ultimate facts alleged, including the specific facts that the petitioner contends warrant reversal or modification of the agency’s proposed action;
(f) A statement of the specific rules or statutes that the petitioner contends require reversal or modification of the agency’s proposed action; and
(g) A statement of the relief sought by the petitioner, stating precisely the action that the petitioner wishes the agency to take with respect to the agency’s proposed action.
A petition that does not dispute the material facts on which the Department’s action is based shall state that no such facts are in dispute and otherwise shall contain the same information as set forth above, as required by Rule 28-106.301, Florida Administrative Code. Under paragraphs 120.569(2)(c) and (d), Florida Statutes, a petition for administrative hearing must be dismissed by the agency if the petition does not substantially comply with the above requirements or is untimely filed.
This intent to issue a variance constitutes an order of the Department. Subject to the provisions of Section 120.68(7)(a), Florida Statutes, which may require a remand for an administrative hearing, the applicant has the right to seek judicial review of the order under Section 120.68, Florida Statutes, by the filing of a notice of appeal under rule 9.110 of the Florida Rules of Appellate Procedure with the Clerk of the Department in the Office of General Counsel, 3900 Commonwealth Boulevard, Mail Station 35, Tallahassee, Florida 32399‑3000; and by filing a copy of the notice of appeal accompanied by the applicable filing fees with the appropriate district court of appeal. The notice of appeal must be filed within 30 days from the date when the order is filed with the Clerk of the Department.
