Universal Citation: AZ Admin Code R 12-15-904

Current through Register Vol. 30, No. 38, September 20, 2024

A. A responsible party using one of the water measuring methods described in R12-15-903 shall file, with the annual report required by A.R.S. Title 45 and on a form prescribed by the Director, the following information, unless that information has not changed from that submitted in the annual report filed in the previous calendar year.

1. The approved measuring method used;

2. The type of approved measuring device used;

3. The make, model, and size of the approved measuring device used.

B. Except as provided in R12-15-904(B)(5) and R12-15-909(B) and (D), a responsible party shall file with the annual report the information required in subsection (A) of this Section and the following information on a form prescribed by the Director:

1. Totalizing measuring method:
a. The initial totalizing meter reading for the reporting year taken prior to the first use of the measured system during the reporting year;

b. The end totalizing meter reading for the year taken subsequently to the last use of the measured system during the reporting year;

c. The units in which the water is measured;

d. Whether the power meter serves uses other than the pump motor or engine;

e. An estimate of the amount of any water passing through the measured system during measuring device malfunctions;

f. If the well is in operation for more than a 30-day period, the results of a minimum of two flow-rate measurements per reporting year taken under normal system operating conditions. The responsible party shall not submit the results of the flow-rate measurements with the annual report unless a meter malfunction continues longer than 72 hours during the reporting year;

g. The installation or overhaul date of the totalizing meter; and

h. The name of the energy company supplying energy to the responsible party's measured system, its power account number, meter number, total energy consumption for the year, and the type of energy unit.

2. Electrical consumption measuring method:
a. The results of a minimum of two flow-rate measurements per reporting year taken at least 30 days apart and under normal system operating conditions or, if the measured system is used during a single period of 30 days or less during the year, the result of one flow-rate measurement taken during that single period in that year under normal system operating conditions;

b. The dates of the measurements;

c. The discharges in gallons per minute;

d. The time, in seconds, of ten cycles of the electric meter disk, power indicator pulse, or an alternative measurement, provided that the alternative means of measurement is approved in advance by the Director;

e. The inside diameter of the discharge pipe;

f. The multiplier (Kr) and disk constant (Kh) of the electric meter; and

g. The name of the energy company supplying energy to the responsible party's measured system, its power account number, meter number, total energy consumption for the year, and the type of energy unit.

3. Natural gas consumption measuring method:
a. The results of a minimum of two flow-rate measurements per reporting year taken at least 30 days apart and under normal system operating conditions or, if the measured system is used during a single period of 30 days or less during the year, the result of one flow-rate measurement taken during that single period in that year under normal system operating conditions;

b. The dates of the measurements;

c. The discharges in gallons per minute;

d. The amounts of gas per second in cubic feet indicated by the gas meter;

e. The billing factors (F);

f. The inside diameter of the discharge pipe; and

g. The name of the energy company supplying energy to the responsible party's measured system, its power account number, meter number, total energy consumption for the year, and the type of energy unit.

4. Hour meter measuring method:
a. The results of a minimum of two flow-rate measurements per reporting year taken at least 30 days apart and under normal system operating conditions or, if the measured system is used during a single period of 30 days or less during the year, the result of one flow-rate measurement taken during that single period in that year under normal system operating conditions;

b. The dates of the measurements;

c. The discharges in gallons per minute;

d. The initial hour meter reading for the reporting year taken prior to the first use of the measured system during the reporting year;

e. The end hour meter reading taken subsequently to the last use of the measured system during the reporting year;

f. Whether the energy meter serves uses other than the pump motor or engine;

g. The installation or overhaul date of the hour meter; and

h. The name of the energy company supplying energy to the responsible party's measured system, its power account number, meter number, total energy consumption for the year, and the type of energy unit.

5. Elapsed time of flow measuring method: A responsible party using this measuring method shall not be required to submit the following information with the annual report but instead shall record and retain it for three years after the reporting year.
a. The responsible party or agent shall measure and record an initial flow rate taken at the start of flow for each delivery of water;

b. If the flow rate continues for more than eight hours, a subsequent measured flow-rate measurement shall be taken. If any subsequently measured flow-rate differs by more than 10% from the initial flow rate, and the delivery is not adjusted to conform with the initial flow rate, the responsible party or agent shall record the subsequent flow rate;

c. The time the flow begins and the time the flow ends for each delivery of water; and

d. The dates of the measurements.

C. A responsible party or person or entity who uses an approved measuring method or an approved alternative water measurement method shall save the records required by subsections (A) and (B) of this Section for three years after the reporting year.
