INJECTION CONTROL WELLS (PART 1 OF 3)

DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 1

(1) The purpose of Chapter 62-528, F.A.C., Underground Injection Control (UIC), is to protect the quality of the State’s underground sources of drinking water and to prevent degradation of the quality of other aquifers adjacent to the injection zone that may be used for other purposes. This purpose is achieved through rules that govern the construction and operation of injection wells in such a way that the injected fluid remains in the injection zone, and that unapproved interchange of water between aquifers is prohibited.

(2) The permitting concept of a Technical Advisory Committee (TAC), which has been successfully used, is formally described in this rule. The Technical Advisory Committee serves a need for interagency coordination to facilitate the permitting process, and to provide the permitting authorities the advice from the several disciplines necessary to adequately evaluate complex deep injection well system permit applications. A Technical Advisory Committee has been established in each Department District to assist and provide advice to the permitting authority on the technical aspects of underground injection. The Technical Advisory Committee is normally composed of representatives from the Department’s District and Tallahassee offices, the appropriate water management district, local environmental program and the United States Geological Survey (USGS). In addition, the United States Environmental Protection Agency (EPA) shall serve as advisors to the Technical Advisory Committee in order to provide technical assistance regarding any specific matter. The Technical Advisory Committee is chaired by a representative of the Department permitting authority, who is responsible for forwarding the Technical Advisory Committee recommendations to the permitting authority. In the event a water management district also issues a permit, the water management district representative on the Technical Advisory Committee is responsible for forwarding the Technical Advisory Committee recommendations to the water management district permitting authority. As part of its interdisciplinary and interagency role, the TAC provides the means for review and determination by the Department of what is acceptable to or approvable based on the requirements of this rule chapter and chapter 403, F.S. The TAC serves two advisory purposes. It provides expert advice to the District which processes the underground injection control permit. The TAC also works directly with the applicant or permittee in providing expertise at various stages of the permitting process or whenever a decision is needed on a technical matter contained in this chapter. The TAC receives the information, and if requested by the applicant, permittee, or District, will meet always in public. When an applicant or permittee requests an alternative method, material, timeframe or other change contemplated by this chapter, the information to support that request shall be provided to each TAC member, who is listed in the permit or whose name and address is readily available from the Department District office which processes the permit, by whatever means chosen by the applicant or permittee. Any additional information needed by the TAC to make its recommendation to the DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 5

Department shall be transmitted to the applicant or permittee in writing by the District office processing the permit. After receipt of all requested information made available to the members, and based on site-specific factors such as the hydrogeology and ground water quality of the site, either of the following will happen. More discussion with the applicant or permittee will ensue, with a public meeting if a meeting of the TAC is requested or with consideration of the TAC advice, the Department’s District shall transmit in writing its decision concerning the request, consistent with the requirements in this chapter. A permitting authority is not bound by a Technical Advisory Committee recommendation and may reject, modify, or amend the recommendation provided its actions are consistent with the provisions of this chapter. The Department’s decision shall be a permit modification if revision of a permit condition is involved. Any such decision is final agency action subject to the procedural safeguards contained in Chapter 120, F.S. Once a project has had TAC review, minor revisions can be approved by the Department without further TAC review (for example, changes in cement additives, minor changes to well depth, sampling parameters, testing procedures, mechanical integrity testing procedures or casing setting points due to actual field conditions).

62-528.300 Underground Injection Control: General Provisions.

(1) Classification of Injection Wells. Injection wells are classified as follows:

(a) Class I.

1. Wells used by generators of hazardous wastes or owners or operators of hazardous waste management facilities to inject hazardous waste beneath the DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 12

lowermost formation containing, within one quarter mile of the well bore, an underground source of drinking water.

2. Other industrial and municipal (publicly or privately owned) disposal wells which inject fluids beneath the lowermost formation containing, within one quarter mile of the well bore, an underground source of drinking water.

3. Radioactive waste disposal wells that inject fluids below the lowermost formation containing an underground source of drinking water within one-quarter mile of the well bore.

(b) Class II. Wells which inject fluids:

1. Which are brought to the surface in connection with conventional oil or natural gas production and may be commingled with waste waters from gas plants which are an integral part of production operations, unless those waters are classified as a hazardous waste at the time of injection.

2. For enhanced recovery of oil or natural gas; and

3. For storage of hydrocarbons which are liquid at standard temperature and pressure.

(c) Class III. Wells which inject for extraction of minerals, including:

1. Mining of sulfur by the Frasch process;

2. Solution mining of minerals; (Note-Solution mining of minerals includes sodium chloride, potash, phosphate, copper, uranium and any other mineral which can be mined by this process).

(d) Class IV. Wells used by generators of hazardous wastes or of radioactive wastes, by owners or operators of hazardous waste management facilities, or by owners or operators of radioactive waste disposal sites to dispose of hazardous wastes or radioactive wastes:

1. Into or above a formation which, within one quarter mile of the well, contains either an underground source of drinking water, or an exempted aquifer, or

2. Which cannot be classified as a Class I well under Rule 62-528.300(1)(a), F.A.C., or as a Class IV well under subparagraph 1. above.

(e) Class V. Only injection wells not included in Class I, II, III, or IV are Class V wells, which are grouped together for the purpose of permitting:

1. Group 1 – Thermal Exchange Process Wells.

a. Air conditioning return flow wells used to return to any aquifer the water used for heating or cooling. An air conditioning supply well, heat pump, and return flow well used to inject water into the same permeable zone from which it was withdrawn constitute a closed-loop system;

b. Cooling water return flow wells used to inject water previously used for cooling;

2. Group 2 – Aquifer Recharge Wells.

a. Recharge wells used to replenish, augment, or store water in an aquifer;

b. Salt water intrusion barrier wells used to inject water into a fresh water aquifer to prevent the intrusion of salt water into the fresh water;

DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 13 c. Subsidence control wells (not used for the purpose of oil or natural gas production) used to inject fluids into a zone which does not produce oil or gas to reduce or eliminate subsidence associated with the overdraft of fresh water;

d. Connector wells used to connect two aquifers to allow interchange of water between those aquifers;

3. Group 3 – Domestic Wastewater Wells.

a. Wells which are part of domestic wastewater treatment systems excluding wells which are defined as Class I wells under Rule 62-528.300(1)(a)2., F.A.C., used to discharge effluent or reclaimed water from domestic wastewater treatment facilities;

b. Septic system wells used to inject the waste from a multiple dwelling, business establishment, community, or regional business establishment septic tank. This Chapter does not apply to individual or single family domestic waste residential septic systems nor to non-residential septic systems receiving only domestic wastewater which have the capacity to serve fewer than twenty persons per day, and which are regulated under Chapter 64E-6, F.A.C. Septic system wells receiving nondomestic wastewater shall be considered as Group 4 wells;

4. Group 4 – Nondomestic Wastewater Wells.

a. Dry wells used for the injection of wastes into a subsurface formation;

b. Injection wells associated with an aquifer remediation project;

c. Wells other than Class I or Class IV used to inject radioactive waste, provided the concentrations of the waste do not exceed drinking water standards contained in Chapter 62-550, F.A.C.;

d. Desalination process concentrate wells;

5. Group 5 – Mining or Mineral Extraction Wells.

a. Wells used to inject spent brine into the same formation from which it was withdrawn after extraction of halogens or their salts;

Wells used to store and recover effluent or reclaimed water from a domestic wastewater treatment plant shall be permitted as Group 3 wells.

8. Group 8 – Class V Wells Regulated Under Additional Federal Requirements.

a. Large capacity cesspools including multiple dwelling, community or regional cesspools, or other devices that receive sanitary wastes, containing human excreta, which have an open bottom and sometimes perforated sides. The UIC DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 14

requirements do not apply to single family residential cesspools nor to non-residential cesspools that receive solely sanitary waste and have the capacity to serve fewer than 20 persons a day;

b. Motor vehicle waste disposal wells that receive or have received fluids from vehicular repair or maintenance activities, such as an auto body repair shop, automotive repair shop, new or used car dealership, specialty repair shop (e.g., transmission and muffler repair shop), or any facility that does any vehicular repair work. Fluids disposed in these wells may contain organic and inorganic chemicals in concentrations that exceed the maximum contaminant levels (MCLs) established by the primary drinking water regulations (see 40 CFR part 142). These fluids also may include waste petroleum products and may contain contaminants, such as heavy metals and volatile organic compounds, which pose risks to human health;

9. Group 9 – Other Class V Wells.

a. Exploratory wells;

b. Injection wells associated with the recovery of geothermal energy for heating, aquaculture and production of electric power;

c. Swimming pool drainage wells;

(2) Identification of Underground Sources of Drinking Water. The Department will identify by narrative description, illustrations, maps, and other means and shall protect, except where exempted under Rule 62-528.300(3), F.A.C., as an underground source of drinking water, all aquifers or parts of aquifers which meet the definition of an “underground source of drinking water” in Rule 62-528.200(66), F.A.C. Even if an aquifer has not been specifically identified by the Department, it is an underground source of drinking water if it meets the definition in Rule 62-528.200(66), F.A.C., and the criteria in Rule 62-520.410(1), F.A.C.

(3) Identification of and Criteria for Exempted Aquifers.

(a) After notice and opportunity for a public hearing as provided by Rules 62-528.315 through .330, F.A.C., the Department shall identify (by narrative description, illustrations, maps, or other means) and describe in geographic or geometric terms (such as vertical and lateral limits and gradient) which are clear and definite, all aquifers or parts thereof which the Department proposes to designate as exempted aquifers using the criteria in (c) below. No such designation shall be final until approved by the United States Environmental Protection Agency as part of the State program.

(b) Subsequent to program approval, the Department may, after notice and opportunity for a public hearing, identify additional exempted aquifers. Exemption of aquifers identified under (c)2. below are considered major aquifer exemptions and shall be treated as a program revision subject to the provisions of 40 C.F.R. pt. 145.32 (1994) and requiring public notice in the Federal Register. Exemption of aquifers identified under (c)3. below are considered minor aquifer exemptions and shall become final if the Department submits the exemption in writing to the Environmental Protection Agency Administrator, or an authorized delegatee, and the Administrator, or an authorized DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 15

delegatee, has not disapproved the designation within 45 days. Any disapproval by the Administrator shall state the reasons and shall constitute final Environmental Protection Agency action for purposes of judicial review.

(c) To be an exempted aquifer, an aquifer or a portion thereof which meets the criteria for an “underground source of drinking water” in Rule 62-528.200(66)(a), F.A.C., shall meet the following criteria:

1. It does not currently serve as a source of drinking water; and

2. It cannot now and will not in the future serve as a source of drinking water because:

a. It is mineral, hydrocarbon, or geothermal energy producing, or can be demonstrated by a permit applicant for a Class III operation to contain minerals or hydrocarbons that considering their quantity and location are expected to be commercially producible;

b. It is situated at a depth or location which makes recovery of water for drinking water purposes economically or technologically impractical;

c. It is so contaminated that it would be economically or technologically impractical to render that water fit for human consumption; or

d. It is located over a Class III well mining area subject to subsidence or catastrophic collapse, or

3. The total dissolved solids content of the ground water is more than 3,000 and less than 10,000 mg/L and it is not reasonably expected to be or become a supply of drinking water; and

4. Has satisfied the following requirements in accordance with paragraph (b) above:

a. A major aquifer exemption has been approved by the Environmental Protection Agency; or

b. A minor aquifer exemption has not been disapproved by the Environmental Protection Agency.

(d) For Class III wells, the Department shall require an applicant for a permit which necessitates an aquifer exemption under (c)2.a. above to furnish the data necessary to demonstrate that the aquifer is expected to be mineral or hydrocarbon producing. Information contained in the mining plan for the proposed project, such as a map and general description of the mining zone, general information on the mineralogy and geochemistry of the mining zone, analysis of the amenability of the mining zone to the proposed mining method, and a timetable of planned development of the mining zone shall be considered by the Department in addition to the information required by Rule 62-528.450(2), F.A.C. Approval of the aquifer exemption shall be treated as a program revision.

(e) No aquifer exemption request shall be processed until the Department has received the appropriate fee as specified in Rule 62-4.050(4)(o)5. or 6., F.A.C.

(4) Area of Review.

(a) An area of review, which shall apply to each Class I and Class III well, well field, project or area of the State, and for a Class V injection well when required, shall DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 16

be determined by the applicant in a manner that shall take into account the zone of endangering influence, which is the lateral area in which the buoyant forces or increased pressures in the injection zone may cause the migration of the injected or formation fluid into an underground source of drinking water. The area of review is the land surface overlying the zone of endangering influence.

(b) In determining the area of review, the information to be used shall include chemical, physical, and biological characteristics of the injection fluids and formation fluids; hydrogeology; appropriate mathematical models, if available, for computing pressure and concentration changes in the injection zone as a function of distance and time; population; ground water use and dependence; and historical practices in the area. A radius around the injection well of one mile, or two miles for a hazardous waste well, shall be a minimum. In the case of an application for a well field project, a fixed width of not less than one mile for the circumscribing area shall be a minimum.

(5) Corrective Action.

(a) Coverage. Applicants for Class I or Class III injection well permits shall identify, and for any Class V well permit when required by the Department shall identify, the location of all known wells within the area of review for that injection well which penetrate the injection zone or confining zone. For such wells which are in use or improperly sealed, completed, or abandoned, the applicant shall also submit a plan specifying plugging and abandonment, pressure limitations, or such actions or modifications as are necessary to prevent movement of fluid into underground sources of drinking water (“corrective action”). Where the plan is adequate, the Department shall incorporate it into the permit as a condition. Where the Department’s review of an application indicates that the applicant’s plan is inadequate (based on the factors in (b) below) the Department shall require the applicant to revise the plan, prescribe a plan for corrective action as a condition of the permit under (b) below, or deny the application. In no case shall the Department issue a permit without incorporating a plan for corrective action in such permit when such corrective action is required by this subsection.

(b) Criteria and Factors. In determining the adequacy of corrective action proposed by the application under paragraph (a) of this subsection and in determining the additional steps needed to prevent fluid movement into underground sources of drinking water, the following criteria and factors shall be considered by the Department:

1. Nature, volume, and injection rate of the injected fluid;

2. Nature of native fluids, or by-products of injection;

3. Potentially affected population;

4. Geology;

5. Hydrology;

6. History of the injection operation;

7. Completion and plugging records for all wells;

8. Abandonment procedures in effect at the time the well was abandoned;

9. Hydraulic connections with underground sources of drinking water;

10. Life of injection well; and

DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 17 11. Pressure considerations.

(c) Requirements.

1. Existing Injection Wells. Any permit issued for an existing injection well requiring corrective action shall include a compliance schedule requiring any corrective action accepted or prescribed under paragraph (a) of this subsection. In addition, schedules of compliance shall require compliance as soon as possible, but not later than three years after the effective date of the permit.

2. New Injection Wells. No owner or operator of a new injection well shall begin injection until all required corrective action has been completed. The Department shall not authorize construction of a new injection well prior to the completion of all required action unless the applicant can affirmatively demonstrate that such construction will not pose a threat to the quality of the waters of the State. However, operational testing pursuant to Rule 62-528.450(3), F.A.C., shall not be authorized until all corrective action has been completed.

3. If needed to prevent fluid movement into an underground source of drinking water, the Department shall require as a permit condition that injection pressure be so limited that pressure in the injection zone at the site of any improperly completed or abandoned well in the area of review does not exceed a pressure which could cause fluid movement into an underground source of drinking water. This pressure limitation shall satisfy the corrective action requirement. Alternatively, such injection pressure limitation can be part of a compliance schedule and last until all other corrective action has been taken. The Department shall consider alternative methods of control which prevent fluid movement into underground sources of drinking water through wells which are improperly sealed, completed or abandoned within the area of review.

4. Class III Wells Only. When setting corrective action requirements, the Department shall consider the overall effect of the project on the hydraulic gradient in potentially affected underground sources of drinking water, and the corresponding changes in potentiometric surface(s) and flow direction(s) rather than the discrete effect of each well. If a decision is made that corrective action is not necessarily based on the determinations above, the monitoring program required in Rule 62-528.425(2), F.A.C., shall be designed to verify the validity of such determinations.

(6) Mechanical Integrity.

(a) An injection well has mechanical integrity if:

1. There is no leak in the casing, tubing or packer; and

2. There is no fluid movement into an underground source of drinking water through channels adjacent to the injection well bore.

(b) One of the following tests shall be used to evaluate the absence of leaks under subparagraph (a)1. of this subsection.

1. Monitoring of the tubing-casing annulus pressure with sufficient frequency to be representative, as determined by the Department, while maintaining an annulus pressure different from atmospheric pressure measured at the surface, after an initial pressure test pursuant to subparagraph 2. and paragraph (e) of this subsection; or

2. Pressure test of inner casing or tubing. DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 18

(c) The following methods shall be used to determine the absence of fluid movement under subparagraph (a)2. A temperature or noise log, and a radioactive tracer survey. The radioactive tracer survey shall not be required by the Department if such testing may pose a threat to an underground source of drinking water.

(d) The Department shall allow the use of a test to demonstrate mechanical integrity, other than those listed in paragraphs (b) and (c) above, with the written approval of the United States Environmental Protection Agency. (The permittee proposes the alternative to the Department, and the Department seeks the approval from EPA.) If the Environmental Protection Agency has published in the

 

Federal Register an alternative mechanical integrity test method, only written Department approval shall be required before conducting alternative mechanical integrity tests to those specified in (b) and (c) above. The Department approval process is described in Rule 62-528.100(2), F.A.C.

(e) A pressure test required under paragraph (b) above shall be conducted with a liquid at a minimum pressure of 1.5 times the maximum pressure at which the well is to be permitted, or 50 PSI, whichever is higher, for at least one hour. Internal mechanical integrity under subparagraph (a)1. above is demonstrated if there is no more than a five-percent pressure change over the one-hour test period. The pressure used to test wells constructed using tubing and packer shall not exceed the design specifications of the tubing or packer.

(f) In conducting and evaluating the tests enumerated in this rule or others to be allowed by the Department, the permittee and the Department shall apply methods and standards generally accepted in the industry. When the permittee reports the results of mechanical integrity tests to the Department, a description of the test(s), method(s) used, and interpretation of the results shall be included. In making the evaluation, the Department shall review monitoring and other test data submitted since the previous evaluation.

(g) The Department shall require additional or alternative mechanical integrity tests in accordance with 40 C.F.R. §146.8(f) (1996).

(h) A permit for any Class I or III well or injection project which lacks mechanical integrity shall include, and for any Class V well may include, a condition prohibiting injection operations until the permittee affirmatively demonstrates under Rule 62-528.300(6)(a)-(c), F.A.C., that the well has mechanical integrity, or the permittee affirmatively demonstrates that there is no movement of fluid into or between underground sources of drinking water.

(7) Confidential Information. In addition to the provision in section 403.111, F.S., claims of confidentiality for the following information shall be denied:

(a) The name and address of any permit applicant or permittee, and

(b) Information which deals with the existence, absence, or level of contamination in drinking water.

(8) Quality Assurance/Quality Control. DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 19

(a) All water quality sampling and analyses associated with Class I, Class III, and Class IV injection wells shall be in accordance with a current Department approved quality assurance plan under Rules 62-160.210 and .300(7)(g) through (k), F.A.C.

(b) All Class V injection wells requiring water quality analyses to be performed shall be in accordance with a current Department approved comprehensive quality assurance plan under Rules 62-160.210 and .300(6), F.A.C.

(9) Reuse Requirements.

(a) This subsection applies only to those Class I municipal wells located within, serving a population within, or associated with a domestic wastewater treatment facility located within a water resource caution area as described in Chapter 62-40, F.A.C.

(b) If, after conducting a reuse feasibility study under section 403.064(2), F.S., a permit applicant determines that the reuse of reclaimed water is feasible, the permittee shall implement reuse according to the schedule for implementation contained in the study conducted under section 403.064, F.S., to the degree that reuse is determined to be feasible.

(c) Nothing in this paragraph shall limit the use of a Class I municipal injection well as backup for a reclaimed water reuse system.

62-528.305 Underground Injection Control: Permit Processing.

The time frames in Rule 62-4.055, F.A.C., shall apply to underground injection control permits. However, the failure of the Department to approve or deny a permit for an underground injection well within the 90-day time period shall not result in the automatic approval or denial of the permit and shall not prevent the inclusion of specific permit conditions which are necessary to ensure compliance with applicable statutes or rules. If the Department fails to approve or deny such a permit within the 90-day period, the applicant may petition for a writ of mandamus to compel the Department to act consistently with applicable regulatory requirements.

62-528.410 Well Construction Standards for Class I and III Wells.

(1) General Design Considerations.

(a) All Class I and III wells shall be cased and cemented to prevent the movement of fluids into or between underground sources of drinking water, and to maintain the ground water quality in aquifers above the injection zone that may be used for monitoring or other purposes.

(b) All Class I wells shall be designed and constructed so that they inject into a formation which is beneath the lowermost formation containing, within one quarter mile of the well bore, an underground source of drinking water.

(c) In the design specifications for a Class I well, the applicant shall address the problem of corrosion, proposed protective measure(s), and, when appropriate, proposed methods of monitoring. The applicant shall consider thickness and type of cement, number and thickness of casings, casing material, casing coatings, formation fluid (water) quality, injection fluid quality and life expectancy of the well.

(d) For Class I wells all outer surfaces of uncemented casings or portions of casings shall be coated or otherwise protected against corrosion. This protection shall DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 38

extend for a minimum distance of thirty feet above and below the uncemented portion of the casing.

(e) All Class I injection wells except those municipal wells (publicly or privately owned) injecting noncorrosive wastes, shall inject fluids through tubing with a packer set immediately above the injection zone, or tubing with an approved fluid seal as an alternative. All existing non-municipal wells constructed without tubing and packer or a fluid seal shall modify their design to incorporate a tubing and packer or fluid seal no later than July 1, 1997, or cease injection unless an alternative to a packer has been approved by the Department under subparagraph 1 below. Existing wells receiving non-municipal waste through a tubing and packer shall not be allowed to remove the tubing and packer as long as injection of non-municipal waste continues unless an alternative to a packer has been approved by the Department under subparagraph 1 below. The tubing, packer, and fluid seal shall be designed for the expected service.

1. The use of other alternatives to a packer shall be allowed with the written approval of the Department. To obtain approval, the applicant shall submit to the Department a written request which shall set forth the proposed alternative and all technical data supporting its use. The Department shall approve the request if the applicant demonstrates that the alternative method will reliably provide a comparable level of protection to underground sources of drinking water.

2. In determining and specifying requirements for tubing, packer, or alternatives, the following factors shall be considered:

a. Depth of setting;

b. Characteristics of injection fluid (chemical content, corrosiveness, and density);

c. Injection pressure;

d. Annular pressure;

e. Rate, temperature and volume of injected fluid; and

f. Size of casing.

(f) For Class I wells the following designs are not allowed:

1. Annuli between casings open to the land surface in any injection well, and

2. Monitoring tubes emplaced and cemented in the annulus adjacent to the innermost or injection string of casing.

(g) For all Class I wells, the applicant shall address potential surge and water hammer protection to protect the safety and integrity of any injection well system.

(h) Department approval, as described in Rule 62-528.100(2), F.A.C., is required prior to any of the following:

1. Remedial procedures that alter the basic design specifications, materials, or character of a Class I or III well;

2. Any work requiring the complete removal of the wellhead; or

3. Any injection of fluids other than those authorized under the existing permit.

(2) Exploratory Pilot Hole. The Department shall require an exploratory pilot hole in any Class I well, or for Class III wells, at any proposed injection well site, and DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 39

shall require that the hole be drilled in stages. The Department shall waive the requirements of this subsection if the applicant can demonstrate that they are not needed to protect underground sources of drinking water and that waiving the requirements will not adversely affect the successful construction or operation of the well.

(3) Drilling. A step-by-step drilling plan shall be included in the design specifications for Class I and III wells. The drilling plan shall specify the proposed drilling program, sampling, coring, and testing procedures, and is subject to Department approval.

(a) For Class I wells, a deviation survey shall be run in the pilot hole at least every ninety feet (every three joints) of the portion of the well which is to be cased and at more frequent intervals when necessary to ensure that the casing can be set and centered for cementing. The maximum deviation at each measurement shall not exceed one degree deviation from vertical. The Department recognizes that the design requirements in this section are not necessary in all cases. The Department shall modify these requirements in the construction permit provided that the applicant submits proof that such modification will not adversely affect the successful construction and future operation of the well.

(b) For Class I wells, the Department shall require directional surveys, if, after an analysis of the well design and drilling program, it is needed to verify that the reamed hole has followed the pilot hole. The directional survey shall be conducted during drilling or in the pilot hole and the reamed hole as separate surveys before installation of the casing.

(c) The Department shall require the applicant to demonstrate that when salt is used for density control during drilling it will not adversely affect the establishment of background water quality for monitoring purposes.

(4) Casings.

(a) The casings used in the construction of each newly drilled Class I and III well shall be designed for the life expectancy of the well, and shall be new and unused for Class I wells.

(b) The number, thickness, type of materials, and length of casing shall be sufficient to protect the quality of drinking water resources and the integrity of the well and the confining strata. The final string of casing shall be made of seamless mild steel pipe having a minimum 0.500 inch wall thickness. An applicant who proposes to use pipe composed of other than 0.500 inch wall seamless mild steel for the final casing shall demonstrate that the proposed material and thicknesses will not compromise the integrity or operation of the well.

(c) Exact setting depths of all casings or tubing shall be determined from field data, based on all available information. Department approval shall be obtained prior to installation of the injection casing and the casing which extends to the base of the underground source of drinking water. In order to obtain approval, the permittee shall submit a request to the Department. The Department shall approve the request if the DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 40

proposed setting depth of the casing or tubing meets the requirements of this Chapter and will not adversely affect the operation of the injection well.

(5) Cementing.

(a) The applicant shall submit the proposed cementing program with the design specifications for Class I or III wells. The cement used in the construction of each newly drilled well shall be designed for the life expectancy of the well. In determining and specifying casing and cementing requirements, the following factors shall be considered:

1. Depth to the injection zone;

2. Injection pressure, external pressure, internal pressure, and axial loading;

3. Hole size;

4. Size and grade of all casing strings (wall thickness, diameter, nominal weight, length, joint specification, and construction material);

5. Corrosiveness of injected fluid, formation fluids, and temperatures;

6. Lithology of injection and confining zones; and

7. Type or grade of cement.

(b) Cement must be compatible with the injection fluid, native fluids, and the formation, but in no case less than the quality of American Society of Testing and Materials Type 2 or its equivalent (Standard Specification for Portland Cement, American National Standards Institute/American Society of Testing and Materials C 150-94, 1994, which is incorporated herein by reference).

(c) Applicants shall submit with the design specifications, a list of cement additives which may be needed in the operation. If an additive is not in the design specifications, the applicant shall obtain prior approval for its use from the Department, as described in Rule 62-528.100(2), F.A.C. Accurate records shall be kept and all additives used shall be reported.

(d) During drilling, the use of cement additives approved in (c) above, water/cement ratio, and the type of water used for mixing shall be determined by the applicant, provided the integrity, containment, corrosion protection, and structural strength of the cement are not significantly affected.

(e) Prior to cementing, the hole shall be conditioned to create optimum bonding of the cement to the casing and formation and to prevent channeling.

(f) Cement placement shall be in such a manner that the purposes and characteristics of the cement are retained, and shall be in accordance with “AWWA Standard for Water Wells”, American Water Works Association A100-90, 1990, which is incorporated herein by reference.

(g) The applicant shall submit his cement testing program with the permit application. The purpose of the cement testing program is to ensure that the cement seal is adequate to prevent migration of fluids in channels, microannular space, or voids in the cement. The methods of testing include:

1. Temperature Survey – shall be run within forty-eight hours after cementing;

2. Cement Evaluation Survey. DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 41

(h) During cementing, adequate pressure differentials shall be maintained to prevent collapse or distortion of the casing.

(i) Class I wells.

1. The final string of casing shall have a nominal overdrill of ten inches unless the applicant can affirmatively demonstrate that an overdrill of not less than five inches is sufficient. The annulus surrounding the final string of casing shall have a nominal five inch cement thickness from the bottom of the casing to land surface. The Department recognizes that these design requirements may not be necessary in all cases. The Department shall modify these requirements in the construction permit if the applicant submits proof that such modification will not adversely affect the successful construction and future operation of the well in such a way as to threaten an underground source of drinking water with contamination.

2. The remaining casings shall have a minimum thickness of 2.500 inches of cement surrounding the casings with not less than five inches of overdrill. A nominal ten inch overdrill shall be required with any intermediate string of casing for which an annular monitor tube of up to 2.375 inches maximum outer diameter is to be emplaced. Commensurate increases in the overdrill shall be required for monitor tubes larger than 2.375 inches in outer diameter.

3. The applicant shall include with the cementing program a centralizing program for the purpose of centralizing the casing, to provide adequate annular space around the casing for proper cementing.

(6) Testing During Drilling and Construction of New Class I Wells.

(a) Geophysical surveys and other tests shall be conducted during the drilling and construction of new Class I wells. A descriptive report interpreting the results of such geophysical surveys and tests shall be presented to the Technical Advisory Committee during in-progress reviews, as part of periodic progress reports, or in letter form as appropriate. Such reports shall include field copies of the surveys and test data and analysis results at the level required to support field decisions made during drilling or proposed during in-progress reviews. Such surveys and tests shall include:

1. Deviation checks shall be in accordance with Rule 62-528.410(3), F.A.C. Such checks shall be at sufficiently frequent intervals to assure that vertical avenues for fluid migration in the form of diverging holes are not created during drilling.

2. Such other geophysical surveys and tests as are needed after taking into account the availability of similar data in the area of the drilling site, the construction plan, and the need for additional information that may arise as the construction of the well progresses. In determining which geophysical surveys and tests shall be required, the following geophysical surveys shall be considered for use in the following situations:

a. For surface casing intended to protect underground sources of drinking water a resistivity, sonic survey, gamma ray, spontaneous potential, and mechanical or sonar caliper surveys before the casing is installed, and a cement evaluation or temperature survey after the casing is set and cemented.

b. For intermediate and long strings of casing intended to facilitate injection a resistivity, spontaneous potential, porosity, fracture finder surveys and gamma ray DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 42

surveys before the casing is installed, and a cement evaluation, temperature, or density survey after the casing is set and cemented.

c. For Class I wells in which an annular monitor tube is proposed for other than the final or innermost casing a caliper survey in the reamed hole which is to contain the monitor tube and, a temperature survey in the monitor tube after the monitor tube has been set and cemented.

(b) The following information concerning the injection formation shall be determined or calculated for new Class I wells:

1. Fluid pressure;

62-528.410 Well Construction Standards for Class I and III Wells.

(1) General Design Considerations.

(a) All Class I and III wells shall be cased and cemented to prevent the movement of fluids into or between underground sources of drinking water, and to maintain the ground water quality in aquifers above the injection zone that may be used for monitoring or other purposes.

(b) All Class I wells shall be designed and constructed so that they inject into a formation which is beneath the lowermost formation containing, within one quarter mile of the well bore, an underground source of drinking water.

(c) In the design specifications for a Class I well, the applicant shall address the problem of corrosion, proposed protective measure(s), and, when appropriate, proposed methods of monitoring. The applicant shall consider thickness and type of cement, number and thickness of casings, casing material, casing coatings, formation fluid (water) quality, injection fluid quality and life expectancy of the well.

(d) For Class I wells all outer surfaces of uncemented casings or portions of casings shall be coated or otherwise protected against corrosion. This protection shall DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 38

extend for a minimum distance of thirty feet above and below the uncemented portion of the casing.

(e) All Class I injection wells except those municipal wells (publicly or privately owned) injecting noncorrosive wastes, shall inject fluids through tubing with a packer set immediately above the injection zone, or tubing with an approved fluid seal as an alternative. All existing non-municipal wells constructed without tubing and packer or a fluid seal shall modify their design to incorporate a tubing and packer or fluid seal no later than July 1, 1997, or cease injection unless an alternative to a packer has been approved by the Department under subparagraph 1 below. Existing wells receiving non-municipal waste through a tubing and packer shall not be allowed to remove the tubing and packer as long as injection of non-municipal waste continues unless an alternative to a packer has been approved by the Department under subparagraph 1 below. The tubing, packer, and fluid seal shall be designed for the expected service.

1. The use of other alternatives to a packer shall be allowed with the written approval of the Department. To obtain approval, the applicant shall submit to the Department a written request which shall set forth the proposed alternative and all technical data supporting its use. The Department shall approve the request if the applicant demonstrates that the alternative method will reliably provide a comparable level of protection to underground sources of drinking water.

2. In determining and specifying requirements for tubing, packer, or alternatives, the following factors shall be considered:

a. Depth of setting;

b. Characteristics of injection fluid (chemical content, corrosiveness, and density);

c. Injection pressure;

d. Annular pressure;

e. Rate, temperature and volume of injected fluid; and

f. Size of casing.

(f) For Class I wells the following designs are not allowed:

1. Annuli between casings open to the land surface in any injection well, and

2. Monitoring tubes emplaced and cemented in the annulus adjacent to the innermost or injection string of casing.

(g) For all Class I wells, the applicant shall address potential surge and water hammer protection to protect the safety and integrity of any injection well system.

(h) Department approval, as described in Rule 62-528.100(2), F.A.C., is required prior to any of the following:

1. Remedial procedures that alter the basic design specifications, materials, or character of a Class I or III well;

2. Any work requiring the complete removal of the wellhead; or

3. Any injection of fluids other than those authorized under the existing permit.

(2) Exploratory Pilot Hole. The Department shall require an exploratory pilot hole in any Class I well, or for Class III wells, at any proposed injection well site, and DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 39

shall require that the hole be drilled in stages. The Department shall waive the requirements of this subsection if the applicant can demonstrate that they are not needed to protect underground sources of drinking water and that waiving the requirements will not adversely affect the successful construction or operation of the well.

(3) Drilling. A step-by-step drilling plan shall be included in the design specifications for Class I and III wells. The drilling plan shall specify the proposed drilling program, sampling, coring, and testing procedures, and is subject to Department approval.

(a) For Class I wells, a deviation survey shall be run in the pilot hole at least every ninety feet (every three joints) of the portion of the well which is to be cased and at more frequent intervals when necessary to ensure that the casing can be set and centered for cementing. The maximum deviation at each measurement shall not exceed one degree deviation from vertical. The Department recognizes that the design requirements in this section are not necessary in all cases. The Department shall modify these requirements in the construction permit provided that the applicant submits proof that such modification will not adversely affect the successful construction and future operation of the well.

(b) For Class I wells, the Department shall require directional surveys, if, after an analysis of the well design and drilling program, it is needed to verify that the reamed hole has followed the pilot hole. The directional survey shall be conducted during drilling or in the pilot hole and the reamed hole as separate surveys before installation of the casing.

(c) The Department shall require the applicant to demonstrate that when salt is used for density control during drilling it will not adversely affect the establishment of background water quality for monitoring purposes.

(4) Casings.

(a) The casings used in the construction of each newly drilled Class I and III well shall be designed for the life expectancy of the well, and shall be new and unused for Class I wells.

(b) The number, thickness, type of materials, and length of casing shall be sufficient to protect the quality of drinking water resources and the integrity of the well and the confining strata. The final string of casing shall be made of seamless mild steel pipe having a minimum 0.500 inch wall thickness. An applicant who proposes to use pipe composed of other than 0.500 inch wall seamless mild steel for the final casing shall demonstrate that the proposed material and thicknesses will not compromise the integrity or operation of the well.

(c) Exact setting depths of all casings or tubing shall be determined from field data, based on all available information. Department approval shall be obtained prior to installation of the injection casing and the casing which extends to the base of the underground source of drinking water. In order to obtain approval, the permittee shall submit a request to the Department. The Department shall approve the request if the DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 40

proposed setting depth of the casing or tubing meets the requirements of this Chapter and will not adversely affect the operation of the injection well.

(5) Cementing.

(a) The applicant shall submit the proposed cementing program with the design specifications for Class I or III wells. The cement used in the construction of each newly drilled well shall be designed for the life expectancy of the well. In determining and specifying casing and cementing requirements, the following factors shall be considered:

1. Depth to the injection zone;

2. Injection pressure, external pressure, internal pressure, and axial loading;

3. Hole size;

4. Size and grade of all casing strings (wall thickness, diameter, nominal weight, length, joint specification, and construction material);

5. Corrosiveness of injected fluid, formation fluids, and temperatures;

6. Lithology of injection and confining zones; and

7. Type or grade of cement.

(b) Cement must be compatible with the injection fluid, native fluids, and the formation, but in no case less than the quality of American Society of Testing and Materials Type 2 or its equivalent (Standard Specification for Portland Cement, American National Standards Institute/American Society of Testing and Materials C 150-94, 1994, which is incorporated herein by reference).

(c) Applicants shall submit with the design specifications, a list of cement additives which may be needed in the operation. If an additive is not in the design specifications, the applicant shall obtain prior approval for its use from the Department, as described in Rule 62-528.100(2), F.A.C. Accurate records shall be kept and all additives used shall be reported.

(d) During drilling, the use of cement additives approved in (c) above, water/cement ratio, and the type of water used for mixing shall be determined by the applicant, provided the integrity, containment, corrosion protection, and structural strength of the cement are not significantly affected.

(e) Prior to cementing, the hole shall be conditioned to create optimum bonding of the cement to the casing and formation and to prevent channeling.

(f) Cement placement shall be in such a manner that the purposes and characteristics of the cement are retained, and shall be in accordance with “AWWA Standard for Water Wells”, American Water Works Association A100-90, 1990, which is incorporated herein by reference.

(g) The applicant shall submit his cement testing program with the permit application. The purpose of the cement testing program is to ensure that the cement seal is adequate to prevent migration of fluids in channels, microannular space, or voids in the cement. The methods of testing include:

1. Temperature Survey – shall be run within forty-eight hours after cementing;

2. Cement Evaluation Survey. DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 41

(h) During cementing, adequate pressure differentials shall be maintained to prevent collapse or distortion of the casing.

(i) Class I wells.

1. The final string of casing shall have a nominal overdrill of ten inches unless the applicant can affirmatively demonstrate that an overdrill of not less than five inches is sufficient. The annulus surrounding the final string of casing shall have a nominal five inch cement thickness from the bottom of the casing to land surface. The Department recognizes that these design requirements may not be necessary in all cases. The Department shall modify these requirements in the construction permit if the applicant submits proof that such modification will not adversely affect the successful construction and future operation of the well in such a way as to threaten an underground source of drinking water with contamination.

2. The remaining casings shall have a minimum thickness of 2.500 inches of cement surrounding the casings with not less than five inches of overdrill. A nominal ten inch overdrill shall be required with any intermediate string of casing for which an annular monitor tube of up to 2.375 inches maximum outer diameter is to be emplaced. Commensurate increases in the overdrill shall be required for monitor tubes larger than 2.375 inches in outer diameter.

3. The applicant shall include with the cementing program a centralizing program for the purpose of centralizing the casing, to provide adequate annular space around the casing for proper cementing.

(6) Testing During Drilling and Construction of New Class I Wells.

(a) Geophysical surveys and other tests shall be conducted during the drilling and construction of new Class I wells. A descriptive report interpreting the results of such geophysical surveys and tests shall be presented to the Technical Advisory Committee during in-progress reviews, as part of periodic progress reports, or in letter form as appropriate. Such reports shall include field copies of the surveys and test data and analysis results at the level required to support field decisions made during drilling or proposed during in-progress reviews. Such surveys and tests shall include:

1. Deviation checks shall be in accordance with Rule 62-528.410(3), F.A.C. Such checks shall be at sufficiently frequent intervals to assure that vertical avenues for fluid migration in the form of diverging holes are not created during drilling.

2. Such other geophysical surveys and tests as are needed after taking into account the availability of similar data in the area of the drilling site, the construction plan, and the need for additional information that may arise as the construction of the well progresses. In determining which geophysical surveys and tests shall be required, the following geophysical surveys shall be considered for use in the following situations:

a. For surface casing intended to protect underground sources of drinking water a resistivity, sonic survey, gamma ray, spontaneous potential, and mechanical or sonar caliper surveys before the casing is installed, and a cement evaluation or temperature survey after the casing is set and cemented.

b. For intermediate and long strings of casing intended to facilitate injection a resistivity, spontaneous potential, porosity, fracture finder surveys and gamma ray DEP 2008 UNDERGROUND INJECTION CONTROL 62-528 Effective 10-9-08 42

surveys before the casing is installed, and a cement evaluation, temperature, or density survey after the casing is set and cemented.

c. For Class I wells in which an annular monitor tube is proposed for other than the final or innermost casing a caliper survey in the reamed hole which is to contain the monitor tube and, a temperature survey in the monitor tube after the monitor tube has been set and cemented.

(b) The following information concerning the injection formation shall be determined or calculated for new Class I wells:

1. Fluid pressure;

2. Temperature;

3. Fracture pressure;

4. Other physical and chemical characteristics of the injection matrix; and

5. Physical and chemical characteristics of the formation fluids.

(7) Testing of Completed Class I Wells. Upon completion of construction, the completed wells shall be tested to assure that the wells will function as built. Tests to be performed include:

(a) Cement evaluation survey;

(b) Temperature survey;

(c) Pressure test of the final casing to at least 1.5 times the expected injection pressure or 50 pounds per square inch, whichever is greater, for one hour, with a change in pressure of no more than five percent from the initial test pressure;

(d) Video television survey – from top to bottom of the well for baseline monitoring purposes;

(e) Injection tests;

(f) Withdrawal tests – if necessary and if possible;

(g) Caliper survey; and

(h) Radioactive tracer survey.

(8) Testing of Class III Wells.

(a) Geophysical surveys and other tests shall be conducted during the drilling and construction of new Class III wells. Upon completion of construction, the completed well system shall be tested to assure that the well system will function properly at the designed operation pressures. A descriptive report interpreting the results of such surveys and tests shall be prepared and submitted to the Department. The surveys and tests appropriate to each type of Class III well shall be determined based on the intended function, depth, construction and other characteristics of the well, availability of similar data in the area of the drilling site and the need for additional information as the construction of the well progresses.
