Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-528 - UNDERGROUND INJECTION CONTROL › Section 62-528.605 - Well Construction Standards for Class V Wells

Current through Reg. 50, No. 138; July 16, 2024
(1) The
				variety of Class V wells and their uses dictate a variety of construction
				designs consistent with those uses, and precludes specific construction
				standards for each type of Class V well. However, a well shall be designed and
				constructed for its intended use, in accordance with good engineering
				practices, and the design and construction shall be approved by the Department
				through a permit.
(2) The
				Department shall apply any of the criteria for Class I wells (Rules 62-528.400
				through  62-528.460, F.A.C.) to the
				permitting of Class V wells if the Department determines that without the
				application of Class I permitting criteria, the Class V well may cause or allow
				fluids to migrate into an underground source of drinking water which may cause
				a violation of a primary or secondary drinking water standard contained in
				Chapter 62-550, F.A.C., or minimum criteria contained in Rule
				 62-520.400, F.A.C., or may cause
				fluids of significantly differing water quality to migrate between underground
				sources of drinking water. Class I injection well permitting standards shall
				not be required if the injection fluids meet the primary and secondary drinking
				water quality standards contained in Chapter 62-550, F.A.C., and the minimum
				criteria contained in Rule
				 62-520.400, F.A.C. The process
				for making the determination of which criteria apply is described in subsection
				 62-528.100(2),
				F.A.C.
(3) Class V wells shall be
				constructed so that their intended use does not violate the water quality
				standards of Chapter 62-520, F.A.C., at the point of discharge, except where
				specifically allowed in subsection
				 62-522.300(2),
				F.A.C., provided that the drinking water standards of 40 C.F.R. pt. 142 (1994)
				are met at the point of discharge for projects and facilities described in
				paragraphs  62-522.300(2)(a) and
				(b), F.A.C. Migration or mixing of fluids
				from aquifers of substantively different water quality (through the
				construction or use of a Class V well) shall be prevented by preserving the
				integrity of confining beds between these aquifers through cementing or other
				equally protective method acceptable to the Department.
(4) All Class V wells shall be constructed by
				a Florida licensed water well contractor.
(5) A well completion report defining details
				of construction and describing various formations penetrated by the well shall
				be forwarded to the Department within two days after completion of the drilling
				operation.
(6) Samples of
				formations penetrated shall be obtained during the construction of any major
				Class V well as defined in subsection
				 62-528.200(41),
				F.A.C., and shall be submitted for other Class V wells if needed to demonstrate
				whether the well will operate in compliance with Chapter 62-528, F.A.C. If
				required, samples shall be forwarded to the State Geologist, Florida Geological
				Survey, 903 West Tennessee Street, Tallahassee, Florida 32304, when drilling is
				completed.
(7) All drilled wells
				shall, at a minimum, meet the casing and cementing requirements for water well
				construction set forth in Chapter 62-532, F.A.C.
(8) Class V wells shall not be dynamited
				except with written permission from the Department.
(9) A test well or boring shall be filled
				with cement within five days after completion of the testing for which it was
				drilled. Such test wells or borings shall not be used as drainage wells unless
				a permit has been obtained in accordance with this chapter. Failure to obtain a
				permit prior to drilling of the well or boring shall bar future use except for
				testing purposes not connected with drainage in any
				manner.
