Section Env-Wq 2102.10 - Measurement of Volume of Water Use Required

(a) Each water user that is not an agriculture water user, a limited water user, or the owner of a mobile facility that qualifies for an intermittent registration under Env-Wq 2102.32(a)(1) shall use the methods described in Env-Wq 2102.11 through Env-Wq 2102.15 to measure or quantify:

(1) The monthly volume of withdrawal and discharge for each registered source and destination, respectively;

(2) The 24-hour maximum volume for each month reported, if available; and

(3) The monthly volume(s) of water transferred to or from another facility.

(b) Measuring devices and structures shall register and be calibrated for the full flow range of the withdrawal, diversion, or discharge being measured.

(c) Each individual withdrawal shall be measured separately from other withdrawals at the facility, except that for individual wells registered as a wellfield, measurement of the combined withdrawal shall be accepted.

(d) Each individual discharge at a facility that exceeds 20,000 gallons per day of water shall be measured separately from other discharges at the facility except that the discharge may be reported based on the withdrawal volume if the daily volume of the discharge equals at least 90 percent of the volume of the corresponding withdrawal.

(e) There shall be no turnouts or diversions between the source of water and the measuring devices, except for faucets or other small outlets that have a de minimis effect on the diversion or withdrawal.

(f) In those cases where wells are authorized for the purpose of supplementing surface waters with water from combined sources, both sources of water shall be measured.

(g) A water user shall implement water use measurement approaches which:

(1) Directly or indirectly record the total volume of water pumped; and

(2) Can be used by the department to measure water use when conducting an inspection of a facility.
