Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-671 - PHOSPHATE MINING WASTE TREATMENT REQUIREMENTS › Section 62-671.200 - Definitions

Current through Reg. 50, No. 138; July 16, 2024
The definitions set forth in Title 40, United States Code of
				  Federal Regulations, Part 401 and Section
				   436.181, F.S., are adopted by
				  reference, except where in conflict with the definitions in this rule. In
				  addition, the definitions in Section
				   403.031, F.S., and the following
				  definitions shall apply to this rule:
(1) "Mine" is any area of land, surface or
				underground, used for or resulting from the extraction of phosphate content
				from phosphate bearing materials.
(2) A "New Pollution Source" means any mine
				and beneficiation process for which the construction or operation of the
				industrial wastewater treatment facilities was not permitted before July 20,
				1981. Any mine or beneficiation process for which a complete application to
				construct the industrial waste treatment facilities was filed with the
				Department on or before December 31, 1981, shall be deemed as existing. New
				pollution sources do not include expansions or modifications of existing
				sources.
(3) "Non-filterable,
				Non-volatile Residue (Fixed Solids)" means those solids which represent the
				difference between the total non-filterable residue and the total volatile
				residue determined in accordance with the test methods specified at page 95 of
				the 14th edition of Standard Methods for the Examination of Water and
				Wastewater.
(4) "Normal Working
				Level" of an impoundment means that level resulting from the normal height or
				number of damming boards maintained at the outfall(s) under normal operating
				conditions.
(5) "Points of
				Discharge" means any outfall structure or location where the effluent from the
				mining or beneficiation process leaves the treatment system and enters waters
				of the State. The point of discharge shall be specified in Department permits
				for all discharges from a mining or beneficiation process.
(6) "Sample" means a representative sample of
				the discharge.
(7) "Total
				Non-filterable Residue (Total Suspended Solids)" means those solids which are
				retained by an approved filter and dried to a constant weight at 103º to
				105º C as described at page 94 of the 14th edition of Standard Methods for
				the Examination of Water and Wastewater.
(8) "Total Phosphorus" means the total
				phosphorus in an unfiltered sample measured in milligrams per liter using the
				manual or automated ascorbic acid method following persulfate digestion as
				referenced at pages 476, 481, and 624 of the 14th edition of Standard Methods
				for the Examination of Water and Wastewater or measured in accordance with a
				comparable analytical method approved by the United States EPA or the
				Department.
(9) The "1-Day Maximum"
				means the highest values obtained by the methods specified in this rule of
				total non-volatile, non-filterable residue (fixed solids) and total
				non-filterable residue (suspended solids) or total phosphorus (P) of any sample
				collected as defined in (6) during a 24-hour period.
(10) The "30-Day Average" means the
				flow-weighted arithmetic mean of all the measured pollutant values obtained
				during any calendar month and analyzed in accordance with this rule. However,
				if during any calendar month there are three or less measured pollutant values,
				then the average shall be computed using the most recent four
				values.
