(1) On and after May 17, 1965, no new wells shall be constructed outside the boundaries of a designated groundwater basin nor the supply of water from existing wells outside the boundaries of a designated groundwater basin increased or extended, unless the user makes an application in writing to the state engineer for a permit to construct a well, in a form to be prescribed by the state engineer. The applicant shall specify the particular aquifer from which the water is to be diverted, the beneficial use to which it is proposed to apply such water, the location of the proposed well, the name of the owner of the land on which such well will be located, the average annual amount of water applied for in acre-feet per year, the proposed maximum pumping rate in gallons per minute, and, if the proposed use is agricultural irrigation, a description of the land to be irrigated and the name of the owner thereof, together with such other reasonable information as the state engineer may designate on the form prescribed.
(2) (a) (I) Repealed.
(II) Effective July 1, 2006, upon receipt of an application for a replacement well or a new, increased, or additional supply of groundwater from an area outside the boundaries of a designated groundwater basin, accompanied by a filing fee of one hundred dollars, the state engineer shall make a determination as to whether or not the exercise of the requested permit will materially injure the vested water rights of others.
(b) (I) The state engineer shall issue a permit to construct a well only if:
The state engineer finds, as substantiated by hydrological and geological facts, thatthere is unappropriated water available for withdrawal by the proposed well and that the vested water rights of others will not be materially injured; and
Except as specified in subparagraph (II) of this paragraph (b), the location of theproposed well will be more than six hundred feet from an existing well.
(II) If the state engineer, after a hearing, finds that circumstances in a particular instance so warrant, or if a court decree is entered for the proposed well location after notice has been given in accordance with sub-subparagraph (B) of this subparagraph (II), the state engineer may issue a permit without regard to the limitation specified in sub-subparagraph (B) of subparagraph (I) of this paragraph (b); except that no hearing shall be required and the state engineer may issue a well permit without regard to the limitation specified in sub-subparagraph (B) of subparagraph (I) of this paragraph (b):
If the state engineer notifies the owners of all wells within six hundred feet of theproposed well by certified mail and receives no response within the time set forth in the notice;
If the proposed well is part of a water court proceeding adjudicating the water rightfor the well, or if the proposed well is part of an adjudication of a plan for augmentation or change of water right and if evidence is provided to the water court that the applicant has given notice of the water court application, at least fourteen days before making the application, by registered or certified mail, return receipt requested, to the owners of record of all wells within six hundred feet of the proposed well;
If the proposed well will serve an individual residential site and the proposed pumping rate will not exceed fifteen gallons per minute; except that, if there is an oil and gas well within six hundred feet of the surface location of the proposed well, the state engineer shall notify the owner of such well by certified mail of the proposed well and may issue the well permit subject to the limitations specified in sub-subparagraph (A) of subparagraph (I) of this paragraph (b);
If the proposed well is an oil and gas well and the only wells within six hundred feetof the surface location of the proposed well are oil and gas wells; or
If the proposed well is an oil and gas well, there is an existing production water wellthat is not an oil and gas well within six hundred feet of the surface location of the proposed oil and gas well, the state engineer has provided written notice of the application by certified mail to the owners of such wells that are not oil and gas wells within thirty-five days after receipt of a complete application for the proposed well, and the state engineer has given those to whom notice was provided thirty-five days after the date of mailing of such notice to file comments on the proposed well's application.
The permit shall set forth such conditions for drilling, casing, and equipping wellsand other diversion facilities as are reasonably necessary to prevent waste, pollution, or material injury to existing rights.
(I) The state engineer shall endorse upon the application the date of its receipt, fileand preserve such application, and make a record of such receipt and the issuance of the permit in his office so indexed as to be useful in determining the extent of the uses made from various groundwater sources.
(II) The state engineer shall act upon an application filed under this section within fortyfive days after its receipt.
(3) (a) (I) A permit to construct a well outside the boundaries of a designated groundwater basin issued on or after April 21, 1967, shall expire one year after issuance unless, before the expiration and on forms as may be prescribed by the state engineer, the applicant to whom the permit was issued, or the well construction contractor, furnishes to the state engineer:
Evidence that the well was constructed and that the pump was installed; or
A showing of good cause as to why the well has not been constructed nor the pumpinstalled and an estimate of time necessary to complete the tasks, upon which the state engineer may extend the permit for only one additional period, not to exceed one year. The limitation on the extension of well permits provided in this sub-subparagraph (B) shall not apply to well permits for federally authorized water projects contained in paragraph (d) of this subsection (3). The state engineer shall charge a fee of two hundred dollars for the extension; except that, on and after July 1, 2006, the state engineer shall charge a fee of sixty dollars for the extension.
If the requirements of section 37-92-301 are met, the expiration of any permit pursuant to this paragraph (a) associated with a conditional groundwater right shall not be the sole basis to determine the existence of reasonable diligence toward completion of such conditional water right.
The state engineer may require the metering or other reasonable measurement ofwithdrawals of groundwater pursuant to permits and the reasonable recording and disclosure of such measured withdrawals.
Any permit to construct a well issued by the state engineer prior to April 21, 1967,shall expire on July 1, 1973, unless the applicant furnishes to the state engineer, prior to July 1, 1973, evidence that the water from such well has been put to beneficial use prior to that date. The state engineer shall give notice by certified or registered mail to all persons to whom such permits were issued at the address shown on the state engineer's records, setting forth the provisions of this subsection (3). Such notices shall be mailed not later than December 31, 1971.
If evidence that the well has been constructed and that the pump was installed, asrequired pursuant to paragraph (a) of this subsection (3), has not been received as of the expiration date of the permit to construct a well, the state engineer shall so notify the applicant by certified mail. The notice shall give the applicant the opportunity to submit evidence that the well was constructed and that the pump was installed before the expiration date. The evidence must be received by the state engineer within twenty-one days after receipt of the notice by the applicant and must be accompanied by a filing fee of thirty dollars. If the state engineer finds the evidence to be satisfactory, the permit shall remain in force and effect. The state engineer shall consider any records available in the state engineer's office, any evidence provided to the state engineer, and all other matters set forth in this section in determining whether the permit should remain in force and effect.
In the case of federally authorized water projects wherein well permits are requiredby this section and have been secured, the expiration dates thereof may be extended for additional periods based upon a finding of good cause by the state engineer following a review of any such project at least annually by the state engineer.
(4) (a) In the issuance of a permit to construct a well outside a designated groundwater basin and not meeting the exemptions set forth in section 37-92-602 to withdraw nontributary groundwater or any groundwater in the Dawson, Denver, Arapahoe, and Laramie-Fox Hills aquifers, the provisions of subsections (1) and (2) of this section shall apply.
(b) (I) Permits issued pursuant to this subsection (4) shall allow withdrawals on the basis of an aquifer life of one hundred years.
(II) Subject to the provisions of subsections (1) and (2) of this section, the amount of such groundwater available for withdrawal shall be that quantity of water, exclusive of artificial recharge, underlying the land owned by the applicant or underlying land owned by another:
Who has consented in writing to the applicant's withdrawal; or
Whose consent exists by virtue of a lawful municipal ordinance or a quasi-municipaldistrict resolution in effect prior to January 1, 1985, and which consent was the subject of a water court application for determination of nontributary groundwater rights filed by the affected municipality or quasi-municipal district prior to January 1, 1985; or
Who shall be deemed to have consented to the withdrawal of groundwater pursuantto the provisions of subsection (8) of this section.
(b.5) (I) An applicant claiming to own the overlying land or to have the consent of the owner of the overlying land as contemplated in sub-subparagraph (A) of subparagraph (II) of paragraph (b) of this subsection (4) shall furnish to the state engineer, in addition to evidence of such consent, evidence that the applicant has given notice of the application by registered or certified mail, return receipt requested, no less than ten days prior to the making of the application, to every record owner of the overlying land and to every person who has a lien or mortgage upon, or deed of trust to, the overlying land recorded in the county in which the overlying land is located.
For purposes of this paragraph (b.5), "person" means any individual, partnership,association, or corporation authorized to do business in the state of Colorado, or any political subdivision or public agency thereof, or any agency of the United States.
The provisions of subparagraph (I) of this paragraph (b.5) do not apply to applicantswhose right to withdraw the groundwater has been determined by a valid decree nor to political subdivisions of the state of Colorado, special districts, municipalities, or quasi-municipal districts that have obtained consent to withdraw the groundwater by deed, assignment, or other written evidence of consent where, at the time of application, the overlying land is within the water service area of such entity.
Material injury to vested nontributary groundwater rights shall not be deemed to result from the reduction of either hydrostatic pressure or water level in the aquifer.
The annual amount of withdrawal allowed in any well permits issued under this subsection (4) shall be the same as the amount determined by court decree, if any, and may, if so provided by any such decree, provide for the subsequent adjustment of such amount to conform to the actual aquifer characteristics encountered upon drilling of the well or test holes.
Any right to the use of groundwater entitling its owner or user to construct a well,which right was initiated prior to July 6, 1973, as evidenced by an unexpired well permit issued prior to July 6, 1973, or a current decree, shall not be subject to the provisions of subsection (4) of this section.
Rights to nontributary groundwater outside of designated groundwater basins may bedetermined in accordance with the procedures of sections 37-92-302 to 37-92-305. Such proceedings may be commenced at any time and may include a determination of the right to such water for existing and future uses. Such determination shall be in accordance with subsections (4) and (5) of this section. Claims pending as of October 11, 1983, which have been published pursuant to section 37-92-302 in the resume need not be republished.
In the case of dewatering of geologic formations by withdrawing nontributary groundwater to facilitate or permit mining of minerals:
Except for coal bed methane wells, no well permit is required unless the nontributarygroundwater being removed will be beneficially used. Except for coal bed methane wells, no well permit is required if the nontributary groundwater being removed to facilitate or permit the mining of minerals will be used only by operators within the geologic basin where the groundwater is removed to facilitate or permit the mining of minerals, including: Injection into a properly permitted disposal well; evaporation or percolation in a properly permitted pit; disposal at a properly permitted commercial facility; roadspreading or reuse for enhanced recovery, drilling, well stimulation, well maintenance, pressure control, pump operations, dust control onsite or off-site, pipeline and equipment testing, equipment washing, or fire suppression; discharge into state waters in accordance with the "Colorado Water Quality Control Act", article 8 of title 25, C.R.S., and the rules promulgated under that act; or evaporation at a properly permitted centralized exploration and production waste management facility.
In the issuance of any well permit pursuant to this subsection (7), subsection (4) ofthis section does not apply and subsections (1), (2), and (3) of this section apply; except that, in considering whether the permit shall issue, the requirement that the state engineer find that there is unappropriated water available for withdrawal and the six-hundred-foot spacing requirement in subsection (2) of this section do not apply. The state engineer shall allow the rate of withdrawal stated by the applicant to be necessary to dewater the mine; except that, if the state engineer finds that the proposed dewatering will cause material injury to the vested water rights of others, the applicant may propose, and the permit shall contain, terms and conditions that will prevent such injury. The reduction of hydrostatic pressure level or water level alone does not constitute material injury. Permitting determinations pursuant to this subsection (7) neither confer a water right nor preclude determination of a water right by the water court.
The state engineer may, pursuant to the "State Administrative Procedure Act", article4 of title 24, C.R.S., adopt rules to assist with the administration of this subsection (7). The rulemaking authority includes the promulgation of rules pursuant to which groundwater within formations and basins, in whole or part, is determined to be nontributary for the purposes of this subsection (7). The rules may also provide rule-making and adjudicatory procedures for nontributary determinations to be made after the initial rule-making pursuant to this subsection (7). In all rule-making proceedings authorized by this subsection (7), the state engineer shall afford interested persons the right of cross-examination. Judicial review of all rules promulgated pursuant to this subsection (7), including all nontributary determinations made pursuant to this subsection (7), is in accordance with the "State Administrative Procedure Act"; except that venue for such review lies exclusively with the water judge or judges for the water division or divisions within which the groundwater that is the subject of such rules or determinations is located. In any judicial action seeking to curtail the withdrawal, use, or disposal of groundwater pursuant to this subsection (7) or to otherwise declare such activities unlawful, the court shall presume, subject to rebuttal, that any applicable nontributary determination made by the state engineer is valid. Any rules promulgated pursuant to this subsection (7) must not conflict with existing laws and do not affect the validity of groundwater well permits existing prior to the adoption of such rules.
(8) It is recognized that economic considerations generally make it impractical for individual landowners to drill wells into the aquifers named in this subsection (8) for individual water supplies where municipal or quasi-municipal water service is available and that the public interest justifies the use of such groundwater by municipal or quasi-municipal water suppliers under certain conditions. Therefore, wherever any existing municipal or quasi-municipal water supplier is obligated either by law or by contract in effect prior to January 1, 1985, to be the principal provider of public water service to landowners within a certain municipal or quasimunicipal boundary in existence on January 1, 1985, said water supplier may adopt an ordinance or resolution, after ten days' notice pursuant to the provisions of part 1 of article 70 of title 24, C.R.S., which incorporates groundwater from the Dawson, Denver, Arapahoe, or Laramie-Fox Hills aquifers underlying all or any specified portion of such municipality's or quasimunicipality's boundary into its actual municipal service plan. Upon adoption of such ordinance or resolution, a detailed map of the land area as to which consent is deemed to have been given shall be filed with the state engineer. Upon the effective date of such ordinance or resolution, the owners of land which overlies such groundwater shall be deemed to have consented to the withdrawal by that water supplier of all such groundwater; except that no such consent shall be deemed to be given with respect to any portion of the land if:
Water service to such portion of the land is not reasonably available from said watersupplier and no plan has been established by that supplier allowing the landowner to obtain an alternative water supply;
Such ordinance or resolution is adopted prior to September 1, 1985, and, prior toJanuary 1, 1985, such groundwater was conveyed or reserved or consent to use such groundwater was given or reserved in writing to anyone other than such water supplier and such conveyance, reservation, or consent has been properly recorded prior to August 31, 1985;
Such ordinance or resolution is adopted on or after September 1, 1985, and saidgroundwater has been conveyed or reserved or consent to use such groundwater has been given or reserved in writing to anyone other than such water supplier and such conveyance, reservation, or consent is properly recorded before the effective date of that ordinance or resolution;
Consent to use such groundwater has been given to anyone other than such watersupplier by the lawful effect of an ordinance or resolution adopted prior to January 1, 1985;
Such groundwater has been decreed or permitted to anyone other than such watersupplier prior to the effective date of such ordinance or resolution; or
Such portion of the land is not being served by said water supplier as of the effectivedate of such ordinance or resolution and such groundwater is the subject of an application for determination of a right to use groundwater filed in the water court prior to July 1, 1985.
(9) (a) For the purpose of making the state engineer's consideration of well permit applications for the withdrawal of groundwater from wells described in subsection (4) of this section more certain and expeditious, the state engineer may, to the extent provided in this subsection (9) and pursuant to the "State Administrative Procedure Act", adopt rules and regulations to prescribe reasonable criteria and procedures for the application for, and the evaluation, issuance, extension, and administration of, such well permits. Such rules and regulations shall only be promulgated after the state engineer has conducted a hydrogeologic analysis, the results of which factually support the promulgation and the content of such rules and regulations for any particular aquifer or portion thereof. All such rules and regulations shall allow the withdrawal pursuant to such permits of the full amount of groundwater determined under subsection (4) of this section and shall afford the applicant the opportunity to rebut any presumptive aquifer characteristics. Presumptive aquifer characteristics established by those rules and regulations shall also apply to the determination of rights to groundwater from wells described in subsection (4) of this section by the water judges, subject to rebuttal by any party. In all rule-making proceedings authorized by this subsection (9), the state engineer shall afford interested persons the right of cross-examination. Judicial review of all rules and regulations promulgated pursuant to this subsection (9) shall be in accordance with the "State Administrative Procedure Act"; except that venue for such review shall lie exclusively with the water judge or judges for the water division or divisions within which the subject groundwater is located.
On or before December 31, 1985, the state engineer shall promulgate reasonablerules and regulations applying exclusively to the Dawson, Denver, Arapahoe, and Laramie-Fox Hills aquifers to the extent necessary to assure that the withdrawal of groundwater from wells described in subsection (4) of this section will not materially affect vested water rights to the flow of any natural stream. In no event shall the rules and regulations promulgated under this paragraph (b) require that persons who withdraw nontributary groundwater, as defined in section 37-90-103 (10.5), relinquish the right to consume, by means of original use, reuse, and successive use, more than two percent of the amount of such groundwater which is withdrawn without regard to dominion or control of the groundwater so relinquished, nor shall they require that judicial approval of plans for augmentation providing for such relinquishment be obtained.
Repealed.
(c.5) (I) (A) As to wells that will be completed in the Dawson, Denver, Arapahoe, and Laramie-Fox Hills aquifers and will withdraw groundwater that is not nontributary groundwater, judicial approval of plans for augmentation is required prior to the use of the groundwater.
As to such wells completed in the Dawson aquifer, decrees approving plans for augmentation must provide for the replacement of actual out-of-priority depletions to the stream caused by withdrawals from the wells and must meet all other statutory criteria for the plans.
As to such wells completed in the Denver, Arapahoe, or Laramie-Fox Hills aquifersmore than one mile from any point of contact between any natural stream including its alluvium on which water rights would be injuriously affected by any stream depletion, and any such aquifer, the decrees must provide for the replacement to the affected stream system or systems of a total amount of water equal to four percent of the amount of water withdrawn on an annual basis. As to such wells completed in such aquifers at points closer than one mile to any such contact, the amount of the replacement is determined using the assumption that the hydrostatic pressure level in each such aquifer has been lowered at least to the top of that aquifer throughout that aquifer. The decrees may also require the continuation of replacement after withdrawal ceases if necessary to compensate for injurious stream depletions caused by prior withdrawals from the wells and must meet all other statutory criteria for such plans.
(II) (Deleted by amendment, L. 2015.)
(d) On or before July 1, 1995, the state engineer shall promulgate reasonable rules that apply to the permitting and use of water artificially recharged into the Dawson, Denver, Arapahoe, and Laramie-Fox Hills aquifers. On or before July 1, 2018, the state engineer shall promulgate rules that apply to the permitting and use of water artificially recharged into a nontributary groundwater aquifer. The rules promulgated pursuant to this subsection (9)(d) must effectuate the maximum utilization of aquifers through the conjunctive use of surface and groundwater resources.
Owners of such permits issued pursuant to subsection (4) of this section shall beentitled to the issuance of permits for additional wells to be constructed on the land referred to in subsection (4) of this section. The standards of subsection (4) of this section shall be applied as if the applications for those additional well permits were filed on the same dates that the original applications were filed.
(a) (I) A person shall not, in connection with the extraction of sand and gravel by open mining as defined in section 34-32.5-103 (15), expose groundwater to the atmosphere unless the person has obtained a well permit from the state engineer pursuant to this section. The state engineer shall issue a well permit upon approval by the water court of a plan for augmentation or upon approval by the state engineer of a plan of substitute supply; except that no increased replacement of water shall be required by the water court or the state engineer whenever the operator or owner of land being mined has, prior to January 15, 1989, entered into and continually thereafter complied with a written agreement with a water conservancy district or water users' association to replace or augment the depletions in connection with or resulting from open mining of sand and gravel. The well permit and plan of substitute supply may authorize uses of water incidental to open mining for sand and gravel, including processing and washing mined materials; dust suppression; mined land reclamation including temporary irrigation for revegetation; liner or slurry wall construction; production of concrete and other aggregate-based construction materials; dewatering; and mitigation of impacts from mining and dewatering.
(II) Any person who extracted sand and gravel by open mining and exposed groundwater to the atmosphere after December 31, 1980, shall apply for a well permit pursuant to this section and, if applicable, shall apply for approval of a plan for augmentation or a plan of substitute supply prior to July 15, 1990.
If any groundwater was exposed to the atmosphere in connection with the extractionof sand and gravel by open mining as defined in section 34-32-103 (9), C.R.S., prior to January 1, 1981, no such well permit, plan for augmentation, or plan of substitute supply shall be required to replace depletions from evaporation; except that the burden of proving that such groundwater was exposed prior to January 1, 1981, shall be upon the party claiming the benefit of this exception. Notwithstanding the provisions of this paragraph (b), judgments and decrees entered prior to July 1, 1989, approving plans for augmentation, which plans include the replacement of depletions from such evaporation, shall be given full effect and shall be enforced according to their terms.
Any person who has reactivated or reactivates open mining operations which exposed groundwater to the atmosphere but which ceased activity prior to January 1, 1981, shall obtain a well permit and shall apply for approval of a plan for augmentation or a plan of substitute supply pursuant to paragraph (a) of this subsection (11).
No person who obtains or operates a plan for augmentation or plan of substitutesupply prior to July 1, 1989, shall be required to make replacement for the depletions from evaporation exempted in this subsection (11) or otherwise replace water for increased calls which may result therefrom.
In addition to the well permit filing fee required by subsection (2) of this section, thestate engineer shall collect the following fees for exposing groundwater to the atmosphere for the extraction of sand and gravel by open mining:
For persons who exposed groundwater to the atmosphere on or after January 1, 1981,but prior to July 15, 1989, one thousand five hundred ninety-three dollars; except that, if such plan is filed prior to July 15, 1990, as required by subparagraph (II) of paragraph (a) of this subsection (11), the filing fee shall be seventy dollars if such plan includes ten acres or less of exposed groundwater surface area or three hundred fifty dollars if such plan includes more than ten acres of exposed groundwater surface area;
For persons who expose groundwater to the atmosphere on or after July 15, 1989,one thousand five hundred ninety-three dollars regardless of the number of acres exposed. In the case of new mining operations, such fee shall cover two years of operation of the plan.
For persons who reactivated or who reactivate mining operations that ceased activity prior to January 1, 1981, and enlarge the surface area of any gravel pit lake beyond the area it covered before the cessation of activity, one thousand five hundred ninety-three dollars;
For persons who request renewal of an approved substitute water supply plan priorto the expiration date of the plan, two hundred fifty-seven dollars regardless of the number of acres exposed;
For persons whose approved substitute water supply plan has expired and who submit a subsequent plan, one thousand five hundred ninety-three dollars regardless of the number of acres exposed. An approved plan shall be considered expired if the applicant has not applied for renewal before the expiration date of the plan. The state engineer shall notify the applicant in writing if the plan is considered expired.
For persons whose proposed substitute water supply plan was disapproved and whosubmit a subsequent plan, one thousand five hundred ninety-three dollars regardless of the number of acres exposed. The state engineer shall notify the applicant in writing of disapproval of a plan.
Excluding the well permit filing fee required by subsection (2) of this section, thestate treasurer shall credit all fees collected with an application for approval of a plan for augmentation or a plan of substitute supply to the water resources cash fund created in section 37-80-111.7 (1).
A person who has obtained a reclamation permit pursuant to section 34-32-112, C.R.S., shall be allowed to apply for a single well permit and to submit a single plan for augmentation or a single plan of substitute supply for the entire acreage covered by the reclamation plan without regard to the number of gravel pit lakes placed within such acreage.
(12) (a) In considering any well permit application in water division 3 that involves a new withdrawal of groundwater that will affect the rate or direction of movement of water in the confined aquifer, the state engineer shall recognize that unappropriated water is not made available and injury is not prevented as a result of the reduction of water consumption by nonirrigated native vegetation.
(b) (I) Repealed.
(II) Subparagraph (I) of this paragraph (b) was repealed, effective July 1, 2004; except that nothing in this subsection (12) shall affect the validity of the rules adopted by the state engineer for groundwater withdrawals in water division 3, or affect the applicability of such rules to well permits that have been or will be issued, and judicial decrees that have been or will be entered, for the withdrawal of groundwater in water division 3.
Notwithstanding the amount specified for any fee in this section, the commission byrule or as otherwise provided by law may reduce the amount of one or more of the fees if necessary pursuant to section 24-75-402 (3), C.R.S., to reduce the uncommitted reserves of the fund to which all or any portion of one or more of the fees is credited. After the uncommitted reserves of the fund are sufficiently reduced, the commission by rule or as otherwise provided by law may increase the amount of one or more of the fees as provided in section 24-75-402 (4), C.R.S.
The state engineer may issue permits for augmentation wells only in accordancewith plans for augmentation approved by the water judge for water division 1 and substitute water supply plans approved pursuant to section 37-92-308 that include such wells.
A person withdrawing water from a well pursuant to subsection (1) or (4) of thissection may use graywater through the use of a graywater treatment works, as those terms are defined in section 25-8-103 (8.3) and (8.4), C.R.S., in compliance with the requirements of section 25-8-205 (1)(g), C.R.S. Any limitations on use set forth in the well permit, and the provisions of any decreed plan for augmentation, apply to the use of graywater.
