PURPOSE AND EFFECT: The Federal Clean Water Act requires states to conduct a comprehensive review of their surface water quality standards every three years (“triennial review”). The proposed rule amendments were developed under the current triennial review. Two public workshops were held on September 1, 2005 (Orlando) and September 7, 2005 (Tallahassee). A number of surface water quality criteria are revised and an amendment is made to the opening paragraph in Rule 62-302.530, F.A.C., to take into account natural and statistical variability when evaluating ambient waters for the purposes of determining impairment. In addition, a number of non-substantive, editorial changes are made to update cross-references and correct typographical errors.
SUMMARY: Proposed rule revisions include amendments to surface water quality criteria for Arsenic, Halomethanes, Cadmium, Iron, and Total Coliforms. In addition, clarifying language is proposed in the introductory paragraph to Rule 62-302.530, F.A.C., to take into account natural and statistical variability when evaluating ambient waters for the purposes of determining impairment. Finally, a number of non-substantive, editorial changes are made to update cross-references and correct typographical errors.
SUMMARY OF ESTIMATED REGULATORY COSTS: No Statement of Estimated Regulatory Cost was prepared.
Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

CHAPTER 62-302

SURFACE WATER QUALITY STANDARDS

 

62-302.300  Findings, Intent, and Antidegradation Policy for Surface Water Quality.

(1)  through (9)  No change.

(10)(a) through (b)  No change.

(10)(c)  This is an even-handed and balanced approach to attainment of water quality objectives.  The Commission has specifically recognized that the social, economic and environmental costs may, under certain special circumstances, outweigh the social, economic and environmental benefits if the numerical criteria are enforced statewide.  It is for that reason that the Commission has provided for mixing zones, zones of discharge, site specific alternative criteria, exemptions and other provisions in Chapters 62-302, 62-4, 62-600, and 62-660 62-6, F.A.C.  Furthermore, the continued availability of the moderating provisions is a vital factor providing a basis for the Commission’s determination that water quality standards applicable to water classes in the rule are attainable taking into consideration environmental, technological, social, economic and institutional factors.  The companion provisions of Chapters 62-4, 62-600, 62-660 62-6, F.A.C., approved simultaneously with these Water Quality Standards are incorporated herein by reference as a substantive part of the State’s comprehensive program for the control, abatement and prevention of water pollution.

(10)(d) No change.

(11) through (18)  No change.

62-302.400  Classification of Surface Waters, Usage, Reclassification, Classified Waters.

(1) through (5)  No change.

(6)  Any person regulated by the Department or having a substantial interest in this chapter may seek reclassification of waters of the State by filing a petition with the Secretary in the form required by Section 120.57, F.S. Rule 62-103.040, F.A.C.

(7) through (10)  No change.

(11)  Unless otherwise specified, the following shall apply:

(a)  The landward extent of a classification shall coincide with the landward extent of waters of the state, as defined in Rule 62-340.600 62-301.400, F.A.C.

(b)    No change.

(12) No change.

Specific Authority  403.061, 403.062, 403.087, 403.088, 403.504, 403.704, 403.804 FS.

62-302.500  Surface Waters: Minimum Criteria, General Criteria.

(1)  Minimum Criteria.  All surface waters of the State shall at all places and at all times be free from:

(a)  No change.

(b)  Thermal components of discharges which, alone, or in combination with other discharges or components of discharges (whether thermal or non-thermal):

1.  No change.

2.  Do not comply with applicable provisions of Rule 62-302.520 subsection 62-302.500(3), F.A.C.

(c)  No change.

(2)  General Criteria.

(a) through (d)  No change.

(e)  A violation of any surface water quality criterion as set forth in this chapter chaper constitutes pollution.  For certain pollutants, numeric criteria have been established to protect human health from an unacceptable risk of additional cancer caused by the consumption of water or aquatic organisms.  These numeric criteria are based on annual average flow conditions.  However, this allowable annual average does not relieve any activity from complying with subsection 62-302.500(1), Rule 62-302.530, F.A.C., or any other provision of water quality standards.

(f)  No change.

Specific Authority  403.061, 403.062, 403.087, 403.504, 403.704, 403.804 FS. Law Implemented  403.021, 403.061, 403.087, 403.088, 403.141, 403.161, 403.182, 403.502, 403.702, 403.708 FS.

62-302.530  Table: Surface Water Quality Criteria.

The following table contains both numeric and narrative surface water quality criteria to be applied except within zones of mixing. The left-hand column of the Table is a list of constituents for which a surface water criterion exists. The headings for the water quality classifications are found at the top of the Table. Applicable criteria lie within the Table. The individual criteria should be read in conjunction with other provisions in water quality standards, including Rule 62-302.500, F.A.C. The criteria contained in Rule 62-302.500, F.A.C., also apply to all waters unless alternative or more stringent criteria are specified in Rule 62-302.530, F.A.C. Unless otherwise stated, all criteria express the maximum not to be exceeded at any time.  In applying the numeric and narrative water quality criteria to ambient waters for purposes of assessing water bodies in accordance with sections 305(b) and 303(d) of the Federal Clean Water Act, the Department shall take into account the variability occurring in nature and shall recognize the statistical variability inherent in sampling and testing procedures as set forth in Chapter 62-303, F.A.C. In some cases, there are separate or additional limits, which apply independently of the maximum not to be exceeded at any time. For example, annual average (denoted as "annual avg." in the Table) means the maximum concentration at average annual flow conditions (see subsection 62-302.200(2), F.A.C.).
