(A) A person who has a well permit issued or recorded pursuant to this section and who intends to use a system or method of rooftop precipitation capture that qualifies under subparagraph (I) of this paragraph (f) shall file, on a form prescribed by the state engineer and consistent with this section, a notice and description of the system or method of rooftop precipitation capture to be used in conjunction with the well. No fee shall be charged for the filing of this form.
(B) A person who applies for a new well permit pursuant to paragraph (a) of this subsection (1) and who intends to use a system or method of rooftop precipitation capture that qualifies under subparagraph (I) of this paragraph (f) shall include on the well permit application a description of the system or method of rooftop precipitation capture to be used in conjunction with the well. An applicant under this sub-subparagraph (B) shall pay the well permit application fee pursuant to sub-subparagraph (C) of subparagraph (I) of paragraph (a) of subsection (3) of this section; however, such applicant shall not be required to pay any additional application fee for the rooftop precipitation collection system.
(C) A person who does not intend to construct and use a well, but would otherwise be entitled to the issuance of a well permit pursuant to paragraph (a) of this subsection (1), shall submit an application in the form and manner designated by the state engineer for a permit to install and use a system or method of rooftop precipitation capture and pay a fee in an amount to be determined by the state engineer. If the state engineer determines that the proposed system or method of rooftop precipitation capture meets the requirements of this paragraph (f), the state engineer shall issue a permit for the system or method, but not otherwise.

The record shall include the date the water is claimed to have been first put to beneficial use.
(b) Any owner of an existing well that was constructed prior to May 8, 1972, or has a well permit issued prior to January 1, 1996, under the provisions of this section, and that was put to beneficial use for watering livestock in a confined animal-feeding operation prior to January 1, 1996, and has been used for that purpose, may apply by December 31, 1999, to obtain a new permit for that well up to the extent of its beneficial use prior to January 1, 1996, for watering livestock in that commercial business pursuant to paragraph (c) of subsection (1) of this section. Such well shall be in addition to the one commercial business well allowed in paragraph (c) of subsection (1) of this section. Such an application shall include a sixty dollar filing fee and shall provide documentation of the annual volume of water put to beneficial use from the well. The state engineer shall have the authority to determine the adequacy of the submitted information for the purpose of approving completely, approving in part, or denying the application. Permits issued after January 1, 1996, up to August 5, 1998, shall remain valid thereafter according to the terms and conditions of those permits.
(5) The state engineer shall act upon an application filed under this section within forty-five days after such filing and shall support the ruling with a written statement of the basis therefor.
(6)(a) Any person aggrieved by a decision of the state engineer granting or denying an application under this section may request a hearing before the state engineer pursuant to section 24-4-104, C.R.S .

(b) Any party aggrieved by a final decision of the state engineer granting or denying an application filed under this section may within thirty days after such decision file a petition for review with the district court in the county in which the well is located. Upon receipt of such petition, the designated groundwater judge for the basin in which the well is located shall conduct such hearings, pursuant to section 24-4-106, C.R.S ., as necessary to determine whether or not the decision of the state engineer shall be upheld. In any case in which the state engineer's decision is reversed, the judge shall order the state engineer to grant or deny the application, as such reversal may require, and may specify such terms and conditions as are appropriate.
(7)(a) The board of a groundwater management district may adopt rules that further restrict the issuance of small capacity well permits and use of rooftop precipitation collection systems or graywater treatment works. In addition, the board of a groundwater management district may adopt rules that expand the acre-foot limitations for small capacity wells set forth in this section. However, the board of a groundwater management district shall not allow an annual volume of more than eighty acre-feet for any small capacity well.
(b) The board may institute its rules only after a public hearing. The board shall publish notice of the hearing, stating the time and place of the hearing and describing, in general terms, the rules proposed. Within sixty days after the hearing, the board shall announce the rules adopted and shall publish notice of the action. In addition, the board shall mail, within five days after the adoption of the rules, a copy of the rules to the state engineer.
(c) Any party adversely affected or aggrieved by a rule may, not later than thirty days after the last date of publication, initiate judicial review in accordance with section 24-4-106, C.R.S .; except that venue for judicial review of the rule must be in the district court for the county in which the office of the groundwater management district is located.
(8) A person withdrawing water from a well pursuant to paragraph (a) or (c) of subsection (1) of this section may use graywater through 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 .
