Subsurface discharges are divided into six categories based on pollutants. Each subsurface discharge is then placed into one of four regulatory categories: authorized under the State Plumbing Code, required to obtain an individual waste discharge license (WDL), authorized to discharge by meeting the conditions of this rule (license by rule (LBR)), or prohibited. This chapter is the states companion rule to the federal Underground Injection Control Program (40 CFR, Part 144) and repeals and replaces the rule originally adopted in 1983. Definitions. As used in this chapter, the following terms have the following meanings. Other terms used in this chapter have the meanings set forth at 38 M.R.S.A. 361-A. BOD. Biochemical oxygen demand. The quantity of oxygen utilized by a mixed population of microorganisms in the aerobic oxidation of the organic matter. CERCLA.

Also known as injection well. A bored, drilled or driven shaft whose depth is greater than the largest surface dimension, whether the shaft is typically dry or contains liquid; or a dug hole whose depth is greater than the largest surface dimension; or a subsurface wastewater disposal system. This definition specifically excludes retention basins, lagoons or any ditch or dug hole that is wider than it is deep. Well injection. The subsurface discharge of fluids into or through a well. Classification of wells. The classification of a particular well is determined by the department based upon the following categories and discharge characteristics. The applicable regulatory category and rule section for each well type is indicated in parentheses. Class I wells. Wells that discharge fluids under the following circumstances: Wells used by generators of hazardous waste or owners or operators of hazardous waste management facilities to discharge hazardous waste beneath the lowermost formation containing groundwater; Other industrial and municipal disposal wells that discharge fluids beneath the lowermost formation containing groundwater; or Radioactive waste disposal wells that discharge fluids below the lowermost formation containing groundwater. (Note: Prohibited, see 3C) Class II wells. Wells that discharge fluids: That are brought to the surface in connection with natural gas storage operations, or conventional oil or natural gas production and may be commingled with wastewaters from gas plants that are an integral part of production operations, unless those waters are classified as a hazardous waste at the time of discharge; For enhanced recovery of oil or natural gas; or For storage of hydrocarbons that are liquid at standard temperature and pressure.

(Note: Covered under State Plumbing Code, see 6) Prohibited discharges Prohibition of unauthorized discharge. All subsurface discharges of fluids into or through a well are prohibited, except as authorized in accordance with this chapter; 38 M.R.S.A. 413(1-B) or the fb88 Subsurface Waste Water Disposal Rules, 10-144 CMR 241. Prohibition of movement of fluid into groundwater No owner or operator of a well shall construct, operate, maintain, convert, plug, abandon or conduct any other discharge activity into that well in a manner that allows the movement of fluid containing any pollutant into groundwater, if the presence of that pollutant may cause or contribute to a violation of its groundwater classification as established in 38 M.R.S.A. 470, groundwater classification standards as established in 38 M.R.S.A., 465-C, surface water classification as established in 38 M.R.S.A. 467 et seq., surface water classification standards as established in 38 M.R.S.A., 465, 465-A, and 465-B, applicable drinking water regulations and/or exposure guidelines, including but not limited to primary drinking water regulations under 40 CFR, Part 142, or may adversely affect the health of persons. The owner or operator of the well has the burden of showing that the requirements of this paragraph are met. If at any time the department learns that a Class V well has violated Sections 3(A) or 3(B) above, the department may: Require the owner or operator of the well to obtain a license for subsurface wastewater disposal, pursuant to 38 M.R.S.A. 413 (1-B); or Take enforcement action pursuant to 38 M.R.S.A. 347-A that may require, among other things, that the owner or operator of the well take such actions as necessary to prevent the violation or remediate damage, including, where necessary, closure of the well. Closure of any Class V well must comply with the prohibition of movement of fluid to groundwater, as stated in Section 3(B)(1). The owner or operator must also dispose or otherwise manage any soil, gravel, sludge, liquids or other materials removed from or adjacent to the injection well in accordance with all applicable federal, state and local regulations and requirements. In addition to the provisions established in 38 M.R.S.A, 464 and 470, any reclassification of groundwater in fb88 is subject to approval by the U.S. Environmental Protection Agency in accordance with procedures in 40 CFR, 144.7 and 146.4. Prohibition of Class I, II, and III wells. Discharge of fluids into or through Class I, II or III wells, as described in Section 2(A) through 2(C), is prohibited. Prohibition of certain Class IV wells The subsurface discharge of hazardous waste into or through a Class IV well, as described in Section 2(D)(1) and 2(D)(2), is prohibited. The subsurface discharge of radioactive waste into or through a Class IV well, as described in Section 2(D)(1), is prohibited. Any discharge of radiological, chemical or biological warfare agents or high-level radioactive waste to the waters of the State, directly or indirectly, is prohibited by 38 M.R.S.A. 420(3). Prohibition of certain Class V wells Motor vehicle waste disposal wells The subsurface discharge of pollutants into or through new and existing motor vehicle waste disposal wells, as described in Section 2(E)(1), is prohibited. Closure must comply with the prohibition of fluid movement as described in Section 3(B)(1). Closure options include, but are not limited to, sealing the drain to prevent further discharge, connecting the floor drains to a municipal sewer system or connecting to a holding tank and disposing of the holding tank contents, if allowed, through a publicly-owned treatment works or with a hazardous waste contractor. Closure options also include converting the well to another type of Class V well as described in Section 3(E)(1)(c). Allowing pollutants to discharge to the ground surface, otherwise known as daylighting, is not a closure option. The owner or operator shall also dispose or otherwise manage any soil, gravel, sludge, liquids or other materials removed from or adjacent to the motor vehicle waste disposal well in accordance with all applicable federal, state and local regulations. At least thirty (30) days prior to closing an existing motor vehicle waste disposal well, the owner or operator shall notify the department of his or her intent to close the well. The department may authorize the conversion (reclassification) of a motor vehicle waste disposal well to another type of Class V well. Motor vehicle waste disposal wells may only be converted if: All motor vehicle maintenance activities and fluids are segregated by physical barriers and are not allowed to enter the well; and Discharge or injection of motor vehicle waste is unlikely based on a facilitys compliance history and records showing proper waste disposal. The use of a temporary plug as the means to segregate waste is not sufficient to convert a motor vehicle waste disposal well to another type of Class V well. Large-capacity cesspools The subsurface discharge of wastes into or through large-capacity cesspools, as described in Section 2(E)(3), is prohibited. All large-capacity cesspools existing on or before April 5, 2000 must be closed no later than April 5, 2005. Closure must comply with the prohibition of fluid movement as described in Section 3(B)(1). NOTE: New large-capacity cesspools were prohibited by federal Underground Injection Control regulations (64 FR 56546), effective April 5, 2000. Federal UIC regulations are in accordance with 40 CFR, Parts 9, 144, 145, and 146, as amended at 64 FR 68566 (Dec. 7, 1999) and 67 FR 39593 (June 7, 2002). Closure options include, but are not limited to, conversion to a subsurface wastewater disposal system or connection to a municipal sewer system. Domestic wastewater must be managed in accordance with fb88 Subsurface Waste Water Disposal Rules, 10-144 CMR 241. The owner or operator shall also dispose or otherwise manage any soil, gravel, sludge, liquids or other materials removed from or adjacent to the cesspool in accordance with all applicable federal, state and local regulations. At least thirty (30) days prior to closing a large-capacity cesspool, the owner or operator shall notify the department of his/her intent to close the cesspool. The department will forward a copy of this notice to the Department of Health and Human Services. Prohibition of certain floor drain connections. A floor drain may not be connected to a well, including a drywell or septic system, or to a pipe that discharges to the ground surface (also known as daylighting) if there is a significant potential for industrial, hazardous or toxic liquids or pollutants to discharge into the floor drain. Licensed discharges License required (WDL). An owner or operator of the following types of Class V wells shall obtain a waste discharge license pursuant to 38 M.R.S.A. 413(1-B) prior to installing, operating or maintaining the well, unless the applicant can demonstrate that the wastewater is of similar quality to that of domestic wastewater and is capable of adequate treatment under the conditions described in the fb88 Subsurface Wastewater Disposal Rule. Industrial wells, as described in Section 2(E)(2); Mining and recovery wells, as described in Section 2(E)(9); Experimental technology wells, as described in Section 2(E)(10); Stormwater drainage wells and beneficial use wells receiving stormwater runoff that do not meet the standards specified in 06-096 Chapter 500, Appendix D; or Any Class V well where discharge is authorized by this rule when, following the submission of the inventory information required in Section 5(C), a determination is made by the department that the discharge requires a license. License not required. A license is not required pursuant to 38 M.R.S.A. 413(2-G) for a discharge to groundwaters of the State that occurs in the process of recovering, containing, cleaning up or removing an oil or hazardous substance spill or leak if the discharge complies with the instructions of the Commissioner or the Commissioners designee. Discharges authorized by this rule (LBR). Under the following terms and conditions, discharges from the following injection wells are authorized by this rule without having to obtain an individual waste discharge license pursuant to 38 M.R.S.A. 413(1-B). Class IV wells. As described in Section 2(D)3, injection wells used to help clean up contaminated groundwater, either by injecting solutions to remediate contamination in situ or to return contaminated groundwater that has been treated and is being injected into the same formation from which it was drawn, are authorized by rule if such subsurface discharge of fluids is approved by the U.S. Environmental Protection Agency or the department, pursuant to provisions for cleanup of releases under CERCLA, RCRA, or 38 M.R.S.A., Chapters 11-A, 11-B, and 13-B. The owner or operator of a Class IV well authorized by rule shall comply with inventory requirements found in Section 5(C) and all other provisions of this chapter. Class V wells. Discharges to the following types of Class V wells are authorized by this rule. The owner or operator of a Class V well authorized by rule shall comply with inventory requirements found in Section 5(C) and all other provisions of this chapter. Stormwater drainage wells, as described in Section 2(E)(4) and meeting the standards specified in 06-096 Chapter 500, Appendix D; Other drainage wells, as described in Section 2(E)(5); Beneficial use wells, as described in Section 2(E)(6), either not receiving stormwater or meeting the standards specified in 06-096 Chapter 500, Appendix D if they do receive stormwater; Fluid return wells, as described in Section 2(E)(7); Non-contact cooling water wells, as described in Section 2(E)(8); or Other injection wells, as described in Section 2(E)(11). Inventory required. The owner or operator of a Class IV or Class V well that is authorized by this rule shall submit inventory information on a form provided by the Commissioner. At a minimum, the following information must be submitted prior to discharge. Facility name and physical location; Name and mailing address of legal contact; Ownership of facility; Number and type of well(s), including type and class of well for which authorization under this rule is sought; Characteristics of discharge; Well construction information; and Operating status of well(s). The department may request additional information believed necessary to protect groundwater. Upon review, the department may make a determination that the individual discharge requires a license pursuant to 38 M.R.S.A. 413(1-B) or that the discharge is not permissible and must be terminated. Inventory not required. The owner or operator of a Class V well located at a single-family, detached, residential house is exempt from the inventory requirement described in Section 5(C). Expiration of discharge authorization under this rule. Authorization to discharge under this rule terminates upon a finding by the department that an individual license is required, expires once the well has been properly closed, or at any time the department learns that a Class V well has caused or may cause or contribute to a violation of this Chapter or the classifications and standards for a body of groundwater or surface water, as described in Section 3(B)(1). Well closure must comply with the prohibition of movement of fluid to groundwater, as stated in Section 3(B)(1). The owner or operator shall also dispose or otherwise manage any soil, gravel, sludge, liquids or other materials removed from or adjacent to the injection well in accordance with all applicable federal, state and local regulations and requirements. Discharges exempt from this rule (State Plumbing Code). Pursuant to 38 M.R.S.A. 413(1-B), a waste discharge license is not required for Class VI wells, as described in Section 2(F), that are designed, installed and operated in conformance with the fb88 Subsurface Waste Water Disposal Rules, 10-144 CMR 241, and used for the disposal of domestic wastewater or other wastewater from commercial, industrial or residential sources that is of similar quality (constituents and strength) to that of domestic wastewater.
