Maximum feasible efficiency in the use of water is required on the part of water users throughout the Basin. Effective September 1, 1981 applications under Section 3.8 of the Compact for new water withdrawals subject to review by the Commission shall include and describe water-conserving practices and technology designed to minimize the use of water by municipal, industrial and agricultural users, as provided in this section.

(a) Applications for approval of new withdrawal from surface or ground water sources submitted by a municipality, public authority or private water works corporation whose total average withdrawals exceed one million gallons per day shall include or be in reference to a program prepared by the applicant consisting of the following elements:

(1) Periodic monitoring of water distribution and use, and establishment of a systematic leak detection and control program;

(2) Use of the best practicable water-conserving devices and procedures by all classes of users in new construction or installations, and provision of information to all classes of existing users concerning the availability of water-conserving devices and procedures; and

(3) A contingency plan including use priorities and emergency conservation measures to be instituted in the event of a drought or other water shortage condition. Contingency plans of public authorities or private water works corporations shall be prepared in cooperation with, and made available to, all municipalities in the area affected by the contingency plan, and shall be coordinated with any applicable statewide water shortage contingency plans.

(b) Programs prepared pursuant to paragraph (a) of this section shall be subject to any applicable limitations of public utility regulations of the signatory party in which the project is located.

(c) Applications for approval of new industrial or commercial water withdrawals from surface or ground water sources in excess of an average of one million gallons per day shall contain

(1) A report of the water-conserving procedures and technology considered by the applicant, and the extent to which they will be applied in the development of the project; and

(2) A contingency plan including emergency conservation measures to be instituted in the event of a drought or other water shortage. The report and contingency plan shall estimate the impact of the water conservation measures upon consumptive and non-consumptive water use by the applicant.

(d) Applications for approval of new agricultural irrigation water withdrawals from surface or ground water sources in excess of one million gallons per day shall include a statement of the operating procedure or equipment to be used by the applicant to achieve the most efficient method of application of water and to avoid waste.

(e) Reports, programs and contingency plans required under this section shall be submitted by the applicant as part of the permit application to the state agency having jurisdiction over the project, or directly to the Commission in those cases where the project is not subject to the jurisdiction of a state agency.
