Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-762 - ABOVEGROUND STORAGE TANK SYSTEMS › Section 62-762.891 - Mineral Acid Storage Tank Requirements

Current through Reg. 50, No. 138; July 16, 2024
The purpose of this rule is to minimize the occurrence and
				  environmental risks of discharges from aboveground storage tanks having
				  capacities greater than 110 gallons that contain hydrobromic, hydrochloric,
				  hydrofluoric, phosphoric or sulfuric acid if at least 20 percent by weight of
				  the solution is one of the five listed acids. Mineral acid storage tank systems
				  are only subject to Rule
				   62-762.891, F.A.C.
(1) Definitions. All words and phrases
				defined in Section  376.321, F.S., shall have the
				same meaning when used in this rule unless specifically stated otherwise in
				this rule. See Section
				 376.321, F.S., for the
				definition of the following terms: "Aboveground, " "Facility, " "Flow-through
				process tank, " "Mineral acids, " "Nonresidential, " "Operator, " "Owner, " and
				"Permitted wastewater treatment system." The following words, phrases, or terms
				used in this rule, unless the context indicates otherwise, shall have the
				following meaning:
(a) "Containment and
				integrity plan" or "CIP" means a document designed, created, and maintained at
				a facility, which shall be considered a public record and made available
				pursuant to the provisions of Chapter 119, F.S. The CIP establishes procedures
				for the inspection and maintenance program for tanks storing mineral acids at
				that facility. The inspection and maintenance program shall be designed for the
				chemical and physical characteristics of the specific mineral acid stored, and
				for the specific materials of construction of the tank. The CIP shall be
				designed to ensure control of the specific mineral acid for the expected
				lifetime of the tank. Form
				 62-762.891(1) 
				Containment and Integrity Plan Certification Form, effective date, January
				2017, is hereby adopted and incorporated by reference, and copies are available
				from the Division of Waste Management, Department of Environmental Protection,
				M.S. #4500, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400, or

.
(b) "County" means a locally administered
				governmental program under contract with the Department to perform compliance
				verification activities at facilities with storage tank systems within the
				boundaries stipulated in the applicable contract.
(c) "Discharge" includes, but is not limited
				to, any spilling, leaking, seeping, pouring, misapplying, emitting, emptying,
				or dumping of any mineral acid which occurs and which affects lands and the
				surface and ground waters of the state.
(d) "Discovery" means, as related to a
				discharge, initial detection of mineral acids in ground water or surface water,
				or the initial detection of soil contamination, resulting from the discharge of
				mineral acids in quantities greater than the amounts reportable this
				rule.
(e) "Inspection and
				maintenance plan" means a plan that establishes the procedures used to prevent
				releases of mineral acids.
(f)
				"Liner" means an artificially constructed material of sufficient thickness,
				density, and composition that will contain the discharge of any specified
				mineral acid from an aboveground tank until such time as the mineral acid can
				be neutralized or removed. The liner shall prevent any escape of specified
				mineral acids or accumulated liquid to the soil, surface water, or groundwater
				(except through secondary containment as provided in paragraph
				 62-762.891(1)(g),
				F.A.C.).
(g) "Secondary
				containment" means a system that is used for discharge prevention, and may
				include one or more of the following devices:
1. A double-walled tank,
2. An external liner placed under and around
				each tank, sealed to its supports, and either designed and built to contain a
				minimum of 110 percent of the capacity of the largest tank within the
				containment; or equipped with a drainage system routed to a permitted
				wastewater treatment system or plant recirculating process system that is
				capable of containing any accidental release from the tank, or
3. A system or structure constructed such
				that accidental releases from a tank would be collected by a drainage system
				within the system or structure and routed to a permitted wastewater treatment
				system, or plant recirculating process system, or alternative containment
				system registered with the Department in accordance with Rule
				 62-762.851,
				F.A.C.
(h) "Stationary"
				means a tank or tanks not meant for multiple site use or that remain in one
				location at the facility site for a period of 180 days or longer.
(i) "Tank" means an aboveground stationary
				device that is constructed primarily of non-earthen materials (e.g., concrete,
				metal, plastic, glass) that provides structural support and is designed
				primarily to contain mineral acids. Connected piping from the tank to and
				including the nearest cutoff valve shall be considered part of the tank for
				purposes of this definition. "Tank" does not include flow-through process
				tanks.
