    (415 ILCS 5/14.1) (from Ch. 111 1/2, par. 1014.1)
    Sec. 14.1. Community water supply; minimum setback zone. A minimum setback zone is established for the location of each new community water supply well as follows:
    (a) No new community water supply well may be located within 200 feet of any potential primary or potential secondary source or any potential route.
    (b) No new community water supply well deriving water from fractured or highly permeable bedrock or from an unconsolidated and unconfined sand and gravel formation may be located within 400 feet of any potential primary or potential secondary source or any potential route. Such 400 foot setback is not applicable to any new community water supply well where the potential primary or potential secondary source is located within a site for which certification is currently in effect pursuant to Section 14.5.
    (c) Nothing in this Section shall affect any location and construction requirement imposed in Section 6 of the "Illinois Water Well Construction Code", approved August 20, 1965, as amended, and the regulations promulgated thereunder.
    (d) For the purposes of this Section, a community water supply well is "new" if it is constructed after September 24, 1987.
    (e) Nothing in this Section shall affect the minimum distance requirements for new community water supply wells relative to common sources of sanitary pollution as specified by rules adopted under Section 17 of this Act.

    (415 ILCS 5/14.2) (from Ch. 111 1/2, par. 1014.2)
    Sec. 14.2. New potential source or route; minimum setback zone. A minimum setback zone is established for the location of each new potential source or new potential route as follows:
    (a) Except as provided in subsections (b), (c) and (h) of this Section, no new potential route or potential primary source or potential secondary source may be placed within 200 feet of any existing or permitted community water supply well or other potable water supply well.
    (b) The owner of a new potential primary source or a potential secondary source or a potential route may secure a waiver from the requirement of subsection (a) of this Section for a potable water supply well other than a community water supply well. A written request for a waiver shall be made to the owner of the water well and the Agency. Such request shall identify the new or proposed potential source or potential route, shall generally describe the possible effect of such potential source or potential route upon the water well and any applicable technology‑based controls which will be utilized to minimize the potential for contamination, and shall state whether, and under what conditions, the requestor will provide an alternative potable water supply. Waiver may be granted by the owner of the water well no less than 90 days after receipt of the request unless prior to such time the Agency notifies the well owner that it does not concur with the request.
    The Agency shall not concur with any such request which fails to accurately describe reasonably foreseeable effects of the potential source or potential route upon the water well or any applicable technology‑based controls. Such notification by the Agency shall be in writing, and shall include a statement of reasons for the nonconcurrence. Waiver of the minimum setback zone established under subsection (a) of this Section shall extinguish the water well owner's rights under Section 6b of the Illinois Water Well Construction Code but shall not preclude enforcement of any law regarding water pollution. If the owner of the water well has not granted a waiver within 120 days after receipt of the request or the Agency has notified the owner that it does not concur with the request, the owner of a potential source or potential route may file a petition for an exception with the Board and the Agency pursuant to subsection (c) of this Section.
    No waiver under this Section is required where the potable water supply well is part of a private water system as defined in the Illinois Groundwater Protection Act, and the owner of such well will also be the owner of a new potential secondary source or a potential route. In such instances, a prohibition of 75 feet shall apply and the owner shall notify the Agency of the intended action so that the Agency may provide information regarding the potential hazards associated with location of a potential secondary source or potential route in close proximity to a potable water supply well.
    (c) The Board may grant an exception from the setback requirements of this Section and subsection (e) of Section 14.3 to the owner of a new potential route, a new potential primary source other than landfilling or land treating, or a new potential secondary source. The owner seeking an exception with respect to a community water supply well shall file a petition with the Board and the Agency. The owner seeking an exception with respect to a potable water supply well other than a community water supply well shall file a petition with the Board and the Agency, and set forth therein the circumstances under which a waiver has been sought but not obtained pursuant to subsection (b) of this Section. A petition shall be accompanied by proof that the owner of each potable water supply well for which setback requirements would be affected by the requested exception has been notified and been provided with a copy of the petition. A petition shall set forth such facts as may be required to support an exception, including a general description of the potential impacts of such potential source or potential route upon groundwaters and the affected water well, and an explanation of the applicable technology‑based controls which will be utilized to minimize the potential for contamination of the potable water supply well.
    The Board shall grant an exception, whenever it is found upon presentation of adequate proof, that compliance with the setback requirements of this Section would pose an arbitrary and unreasonable hardship upon the petitioner, that the petitioner will utilize the best available technology controls economically achievable to minimize the likelihood of contamination of the potable water supply well, that the maximum feasible alternative setback will be utilized, and that the location of such potential source or potential route will not constitute a significant hazard to the potable water supply well.
    The Board shall adopt procedural rules governing requests for exceptions under this subsection. The rulemaking provisions of Title VII of this Act and of Section 5‑35 of the Illinois Administrative Procedure Act shall not apply to such rules. A decision made by the Board pursuant to this subsection shall constitute a final determination.
    The granting of an exception by the Board shall not extinguish the water well owner's rights under Section 6b of the Illinois Water Well Construction Code in instances where the owner has elected not to provide a waiver pursuant to subsection (b) of this Section.
    (d) Except as provided in subsections (c) and (h) of this Section and Section 14.5, no new potential route or potential primary source or potential secondary source may be placed within 400 feet of any existing or permitted community water supply well deriving water from an unconfined shallow fractured or highly permeable bedrock formation or from an unconsolidated and unconfined sand and gravel formation. The Agency shall notify the owner and operator of each well which is afforded this setback protection and shall maintain a directory of all community water supply wells to which the 400 foot minimum setback zone applies.
    (e) The minimum setback zones established under subsections (a) and (b) of this Section shall not apply to new common sources of sanitary pollution as specified pursuant to Section 17 and the regulations adopted thereunder by the Agency; however, no such common sources may be located within the applicable minimum distance from a community water supply well specified by such regulations.
    (f) Nothing in this Section shall be construed as limiting the power of any county or municipality to adopt ordinances which are consistent with but not more stringent than the prohibitions herein.
    (g) Nothing in this Section shall preclude any arrangement under which the owner or operator of a new source or route does the following:
        (1) purchases an existing water supply well and
     attendant property with the intent of eventually abandoning or totally removing the well;
        (2) replaces an existing water supply well with a
     new water supply of substantially equivalent quality and quantity as a precondition to locating or constructing such source or route;
        (3) implements any other arrangement which is
     mutually agreeable with the owner of a water supply well; or
        (4) modifies the on‑site storage capacity at an
     agrichemical facility such that the volume of pesticide storage does not exceed 125% of the available capacity in existence on April 1, 1990, or the volume of fertilizer storage does not exceed 150% of the available capacity in existence on April 1, 1990; provided that a written endorsement for an agrichemical facility permit is in effect under Section 39.4 of this Act and the maximum feasible setback is maintained. This on‑site storage capacity includes mini‑bulk pesticides, package agrichemical storage areas, liquid or dry fertilizers, and liquid or dry pesticides.
    (h) A new potential route, which is an excavation for stone, sand or gravel and which becomes active on lands which were acquired or were being held as mineral reserves prior to September 24, 1987, shall only be subject to the setback requirements of subsections (a) and (d) of this Section with respect to any community water supply well, non‑community water system well, or semi‑private water system well in existence prior to January 1, 1988.

    (415 ILCS 5/14.3) (from Ch. 111 1/2, par. 1014.3)
    Sec. 14.3. Community water supply; maximum setback zone. A maximum setback zone may be established for a community water supply well as follows:
    (a) Owners of community water supplies which utilize any water well, or any county or municipality served by any community water supply well, may determine the lateral area of influence of the well under normal operational conditions. The Agency shall adopt procedures by which such determinations may be made including, where appropriate, pumping tests and estimation techniques.
    (b) Where the results of any determination made pursuant to subsection (a) of this Section disclose that the distance from the well to the outermost boundary of the lateral area of influence of the well under normal operational conditions exceeds the radius of the minimum setback zone established for that well pursuant to Section 14.2, any county or municipality served by such water supply may in writing request the Agency to review and confirm the technical adequacy of such determination. The Agency shall, within 90 days of the request, notify the county or municipality whether the determination is technically adequate for describing the outer boundary of drawdown of the affected groundwater by the well under normal operational conditions. Any action by the Agency hereunder shall be in writing and shall constitute a final determination of the Agency.
    (c) Upon receipt of Agency confirmation of the technical adequacy of such determination, the county or municipality may, after notice and opportunity for comment, adopt an ordinance setting forth the location of each affected well and specifying the boundaries of a maximum setback zone, which boundaries may be irregular. In no event, however, shall any portion of such a boundary be in excess of 1,000 feet from the wellhead, except as provided by subsection (f) of this Section. Such ordinance shall include the area within the applicable minimum setback zone and shall incorporate requirements which are consistent with but not more stringent than the prohibitions of this Act and the regulations promulgated by the Board under Section 14.4, except as provided by subsection (f) of this Section. Upon adoption, the county or municipality shall provide a copy of the ordinance to the Agency. Any county or municipality which fails to adopt such an ordinance within 2 years of receipt of Agency confirmation of technical adequacy may not proceed under the authority of this Section without obtaining a new confirmation of the technical adequacy pursuant to subsection (b) of this Section.
    (d) After July 1, 1989, and upon written notice to the county or municipality, the Agency may propose to the Board a regulation establishing a maximum setback zone for any well subject to this Section. Such proposal shall be based upon all reasonably available hydrogeologic information, include the justification for expanding the zone of wellhead protection, and specify the boundaries of such zone, no portion of which boundaries shall be in excess of 1,000 feet from the wellhead. Such justification may include the need to protect a sole source of public water supply or a highly vulnerable source of groundwater, or an Agency finding that the presence of potential primary or potential secondary sources or potential routes represents a significant hazard to the public health or the environment. The Agency may proceed with the filing of such a proposal unless the county or municipality, within 30 days of the receipt of the written notice, files a written request for a conference with the Agency. Upon receipt of such a request, the Agency shall schedule a conference to be held within 90 days thereafter. At the conference, the Agency shall inform the county or municipality regarding the proposal. Within 30 days after the conference, the affected unit of local government may provide written notice to the Agency of its intent to establish a maximum setback zone in lieu of the Agency acting on a proposal. Upon receipt of such a notice of intent, the Agency may not file a proposal with the Board for a period of 6 months. Rulemaking proceedings initiated by the Agency under this subsection shall be conducted by the Board pursuant to Title VII of this Act, except that subsection (b) of Section 27 shall not apply.
    Nothing in this Section shall be construed as limiting the general authority of the Board to promulgate regulations pursuant to Title VII of this Act. Nothing in this subsection shall limit the right of any person to participate in rulemaking proceedings conducted by the Board under this subsection.
    (e) Except as provided in subsection (c) of Section 14.2, no new potential primary source shall be placed within the maximum setback zone established for any community water supply well pursuant to subsection (c) or (d) of this Section. Nothing in this subsection shall be construed as limiting the power of any county or municipality to adopt ordinances which are consistent with but not more stringent than the prohibition as stated herein.
    (f) If an active community water supply well is withdrawing groundwater from within the alluvial deposits and is located within 1000 feet of public waters, the boundaries of a maximum setback zone adopted by ordinance pursuant to subsection (c) may be established to a distance of 2,500 feet from the wellhead. No new potential route shall be placed, operated or utilized within the maximum setback zone established for any community water supply well pursuant to this subsection. Restrictions provided in subsection (e) shall not be applied beyond 1,000 feet from the wellhead for maximum setback zones adopted pursuant to this subsection. An ordinance which creates a maximum setback zone as described by this subsection shall also be consistent with subsections (a), (b) and (c) of this Section, including incorporation of requirements which are consistent with but no more stringent than the prohibitions of this Act. For purposes of this subsection, the term "public waters" means public waters as defined in Section 18 of the Rivers, Lakes, and Streams Act, as now or hereafter amended.

    (415 ILCS 5/14.4) (from Ch. 111 1/2, par. 1014.4)
    Sec. 14.4. Groundwater rules.
    (a) No later than January 1, 1989, the Agency, after consultation with the Interagency Coordinating Committee on Groundwater and the Groundwater Advisory Council, shall propose regulations to the Board prescribing standards and requirements for the following activities:
        (1) landfilling, land treating, surface impounding
     or piling of special waste and other wastes which could cause contamination of groundwater and which are generated on the site, other than hazardous, livestock and landscape waste, and construction and demolition debris;
        (2) storage of special waste in an underground
     storage tank for which federal regulatory requirements for the protection of groundwater are not applicable;
        (3) storage and related handling of pesticides and
     fertilizers at a facility for the purpose of commercial application;
        (4) storage and related handling of road oils and
     de‑icing agents at a central location; and
        (5) storage and related handling of pesticides and
     fertilizers at a central location for the purpose of distribution to retail sales outlets.
    In preparing such regulation, the Agency shall provide as it deems necessary for more stringent provisions for those activities enumerated in this subsection which are not already in existence. Any activity for which such standards and requirements are proposed may be referred to as a new activity. For the purposes of this Section, the term "commercial application" shall not include the use of pesticides or fertilizers in a manner incidental to the primary business activity.
    (b) No later than October 1, 1993, the Board shall promulgate appropriate regulations for existing activities. In promulgating these regulations, the Board shall, in addition to the factors set forth in Title VII of this Act, consider the following:
        (1) appropriate programs for water quality
     monitoring;
        (2) reporting, recordkeeping and remedial response
     measures;
        (3) appropriate technology‑based measures for
     pollution control; and
        (4) requirements for closure or discontinuance of
     operations.
    Such regulations as are promulgated pursuant to this subsection shall be for the express purpose of protecting groundwaters. The applicability of such regulations shall be limited to any existing activity which is located:
        (A) within a setback zone regulated by this Act,
     other than an activity located on the same site as a non‑community water system well and for which the owner is the same for both the activity and the well; or
        (B) within a regulated recharge area as delineated
     by Board regulation, provided that:
            (i) the boundary of the lateral area of
         influence of a community water supply well located within the recharge area includes such activity therein;
            (ii) the distance from the wellhead of the
         community water supply to the activity does not exceed 2500 feet; and
            (iii) the community water supply well was in
         existence prior to January 1, 1988.
    In addition, the Board shall ensure that the promulgated regulations are consistent with and not pre‑emptive of the certification system provided by Section 14.5. The Board shall modify the regulations adopted under this subsection to provide an exception for existing activities subject to Section 14.6.
    (c) Concurrently with the action mandated by subsection (a), the Agency shall evaluate, with respect to the protection of groundwater, the adequacy of existing federal and State regulations regarding the disposal of hazardous waste and the offsite disposal of special and municipal wastes. The Agency shall then propose, as it deems necessary, additional regulations for such new disposal activities as may be necessary to achieve a level of groundwater protection that is consistent with the regulations proposed under subsection (a) of this Section.
    (d) Following receipt of proposed regulations submitted by the Agency pursuant to subsection (a) of this Section, the Board shall promulgate appropriate regulations for new activities. In promulgating these regulations, the Board shall, in addition to the factors set forth in Title VII of this Act, consider the following:
        (1) appropriate programs for water quality
     monitoring, including, where appropriate, notification limitations to trigger preventive response activities;
        (2) design practices and technology‑based measures
     appropriate for minimizing the potential for groundwater contamination;
        (3) reporting, recordkeeping and remedial response
     measures; and
        (4) requirements for closure or discontinuance of
     operations.
    Such regulations as are promulgated pursuant to this subsection shall be for the express purpose of protecting groundwaters. The applicability of such regulations shall be limited to any new activity which is to be located within a setback zone regulated by this Act, or which is to be located within a regulated recharge area as delineated by Board regulation. In addition, the Board shall ensure that the promulgated regulations are consistent with and not pre‑emptive of the certification system provided by Section 14.5. The Board shall modify the regulations adopted under this subsection to provide an exception for new activities subject to Section 14.6.
    (e) Nothing in this Section shall be construed as prohibiting any person for whom regulations are promulgated by the Board pursuant to subsection (b) or (c) of this Section, from proposing and obtaining, concurrently with the regulations proposed by the Agency pursuant to subsection (a) of this Section, a rule specific to individual persons or sites pursuant to Title VII of this Act which codifies alternative groundwater protection methods that provide substantially equivalent protection for community water supplies.
    (f) Nothing in this Section shall be construed as limiting the power of any county or municipality to adopt ordinances, which are consistent with but not more stringent than the regulations adopted by the Board pursuant to this Section, for application of standards and requirements within such setback zones as are provided by this Act.
    (g) The Agency shall prepare a groundwater protection regulatory agenda for submittal to the Interagency Coordinating Committee on Groundwater and the Groundwater Advisory Council. In preparing this agenda, the Agency shall consider situations where gaps may exist in federal or State regulatory protection for groundwater, or where further refinements could be necessary to achieve adequate protection of groundwater.
    (h) Nothing in this Section shall be construed as limiting the general authority of the Board to promulgate regulations pursuant to Title VII of this Act.
    (i) The Board's rulemaking with respect to subsection (a)(3) of this Section shall take into account the relevant aspects of the Department of Agriculture's Part 255 regulations which specify containment rules for agrichemical facilities.

    (415 ILCS 5/14.5) (from Ch. 111 1/2, par. 1014.5)
    Sec. 14.5. (a) The Agency shall administer a certification system for sites which represent a minimal hazard with respect to contamination of groundwaters by potential primary or potential secondary sources. No later than January 1, 1988, the Agency shall develop and make available a minimal hazard certification form and guidelines for the use and management of containers and above ground tanks, and for the piling of waste.
    (b) After January 1, 1988, the owner of any site which would otherwise be subject to the provisions of subsection (d) of Section 14.2 or Section 14.4 and regulations adopted thereunder may provide a certification of minimal hazard to the Agency if the following conditions are met:
        (1) no on‑site landfilling, land treating, or
     surface impounding of waste, other than landscape waste or construction and demolition debris, has taken place and such circumstance will continue;
        (2) no on‑site piles of special or hazardous waste
     are present and such circumstance will continue, and any piling of other wastes which could cause contamination of groundwater will be consistent with guidelines developed by the Agency;
        (3) no underground storage tanks are present on the
     site and such circumstances will continue;
        (4) use and management of containers and above
     ground tanks will be consistent with guidelines developed by the Agency;
        (5) no on‑site release of any hazardous substance or
     petroleum has taken place which was of sufficient magnitude to contaminate groundwaters;
        (6) no more than 100 gallons of either pesticides or
     organic solvents, or 10,000 gallons of any hazardous substances, or 30,000 gallons of petroleum, will be present at any time; and
        (7) notice has been given to the owner of each
     community water supply well within 1,000 feet of the site.
    (c) Upon receipt of a certification pursuant to subsection (b) of this Section the Agency shall, within 90 days, take one of the following actions:
        (1) notify the owner of the site in writing that the
     certification is complete and adequate;
        (2) notify the owner of the site in writing that the
     certification is not adequate, including a statement of the reasons therefor;
        (3) notify the owner of the site in writing that a
     site inspection will be held within 120 days, and that following such inspection but still within the 120 day period further action will be taken pursuant to item (1) or (2) of this subsection; or
        (4) notify in writing the owner of the site that
     pursuant to Section 17.1 a county or municipality is conducting a groundwater protection needs assessment or the Agency is conducting a well site survey which encompasses the site for which certification is being processed, and specify a time period, not to exceed a total of 180 days from the date of the notice, for consideration of the findings from such assessment or survey and by which further action will be taken pursuant to item (1) or (2) of this subsection.
    A certification is not adequate if it fails to address each of the conditions required to be met by subsection (b) of this Section, or if the Agency possesses information which reasonably suggests that any statement made in the certification is inaccurate or incomplete. Action under item (1) or (2) of this subsection shall constitute a final determination of the Agency.
    (d) When a certification has been provided with respect to which the Agency has made a finding of adequacy or has failed to act in a timely manner pursuant to subsection (c) of this Section, the site shall not be subject to the provisions of subsection (d) of Section 14.2 or Section 14.4 and regulations adopted thereunder for the following time periods:
        (1) one year, if the Agency has failed to act in a
     timely manner pursuant to subsection (c) of this Section, during which time the owner must recertify to continue such status;
        (2) three years, if the site is located within a
     minimum or maximum setback zone, during which time the owner must recertify to continue such status;
        (3) five years, if the site is located within a
     regulated recharge area, during which time the owner must recertify to continue such status; or
        (4) 90 days past the time when a change of ownership
     takes place, during which time the new owner must recertify to continue such status.
    (e) During the effective period of a certification, the owner of the site shall maintain compliance with the conditions specified in subsection (b) of this Section. Any failure by the owner to maintain such compliance shall be just cause for decertification by the Agency. Such action may only be taken after the Agency has provided the owner with a written notice which identifies the noncompliance and specifies a 30 day period during which a written response may be provided by the owner. Such response may describe any actions taken by the owner which relate to the conditions of certification. If such response is deficient or untimely, the Agency shall serve notice upon the owner that the site has been decertified and is subject to the applicable provisions of subsection (d) of Section 14.2 or Section 14.4 and regulations adopted thereunder. Such notification shall constitute a final determination of the Agency.
    (f) The Agency shall maintain a master listing, indexed by county, of those sites for which certifications are in effect. Upon the establishment of a regional planning committee pursuant to Section 17.2, the Agency shall provide a copy of the pertinent portions of such listing to such committee on a quarterly basis. The Agency shall also make copies of such listing available to units of local government and the public upon request.
    (g) The Agency may enter into a written delegation agreement with any county or municipality, which has adopted an ordinance consistent with Section 14.2 or 14.3, to administer the provisions of this Section. Such delegation agreements shall require that the work to be performed thereunder shall be in accordance with criteria established by the Agency, be subject to periodic review by the Agency, and shall include such financial and program auditing by the Agency as may be necessary.
