NR 856.30 NR 856.30 Measurement and reporting requirements.

NR 856.30(1) (1) A person registered under this chapter shall determine the monthly volume of water withdrawn from the property or public water supply, or the monthly volume of water diverted, using methods and procedures set forth in s. NR 856.31.

NR 856.30(2) (2) A person registered under this chapter that makes a withdrawal that averages 100,000 gallons per day or more in any 30-day period, or diverts any amount of water, shall annually report to the department the monthly volumes of the withdrawal or diversion. Reports shall be submitted to the department in the manner prescribed by the department by March 1 of every year and shall contain all of the following information about the previous year’s withdrawals:

NR 856.30(2)(a) (a) Monthly volumes of withdrawal for each source on the property or in the public water supply and if applicable, the monthly volumes of diversion.

NR 856.30(2)(b) (b) The estimated volumes of each use made of the water.

NR 856.30(2)(c) (c) Method or methods used to measure the withdrawals or diversion.

NR 856.30(2)(d) (d) A statement advising the department if the withdrawal was at a level greater than or equal to 1,000,000 gallons per day for 30 consecutive days.

NR 856.30(2)(e) (e) Estimated or actual water loss from consumptive use. Water loss and consumptive use estimations and calculations shall follow the requirements of ch. NR 142.

NR 856.30(2)(f) (f) Method or methods used to determine water loss from consumptive use.

NR 856.30(3) (3) Withdrawal information shall be made available to the department upon request.

NR 856.30(4) (4) The owner shall maintain records of the withdrawal or diversion for a minimum of three years. Records include monthly volumes of withdrawal and, if applicable, diversion; methods used to measure or estimate the withdrawal or diversion; calibration records of meters; and any other pertinent documents necessary to calculate or estimate the withdrawal or diversion volume.

NR 856.30(5) (5) When a property or portion of a property is transferred to another person, the previous owner shall provide copies of the records identified in sub. (4) to the new owner of the property. The new owner is responsible for reporting all withdrawals that occurred during the calendar year as required in sub. (2).

NR 856.31 NR 856.31 Measurement methods and frequency.

NR 856.31(1) (1) Withdrawals shall be measured in accordance with the following methods:

NR 856.31(1)(a) (a) Sources that flow or are pumped at a rate of 70 or more gallons per minute shall be measured using one of the following methods:

NR 856.31(1)(a)1. 1. Totalizing flow meter. Flow meters shall be read and documented at least once every month.

NR 856.31(1)(a)2. 2. Pump operation is timed with an hour meter and the pumping capacity is used to calculate total pumpage. The operation time and pumping capacity shall be documented for each period of use.

NR 856.31(1)(a)3. 3. Flow rate is measured using a weir. For sources with little or no flow rate variability, flow rate shall be measured on a daily basis for the first week and at a minimum of weekly thereafter. For sources with flow rate variability, flow rate shall be measured daily.

NR 856.31(1)(a)4. 4. Flow rate is measured by discharge from a horizontal pipe. Flow rate shall be measured on a daily basis for the first week and at a minimum of weekly thereafter.

NR 856.31(1)(a)5. 5. Alternative method and monitoring frequency that has been approved by the department.

NR 856.31(1)(b) (b) Sources that flow or are pumped at a rate of less than 70 gallons per minute shall be measured using one of the following methods:

NR 856.31(1)(b)1. 1. Totalizing flow meter. Flow meters shall be read and documented at least once every month.

NR 856.31(1)(b)2. 2. Pump operation is timed with an hour meter and the pumping capacity is used to calculate total pumpage. The operation time and pumping capacity shall be documented for each period of use.

NR 856.31(1)(b)3. 3. Flow rate is measured using a weir. For sources with little or no flow rate variability, flow rate shall be measured on a daily basis for the first week and at a minimum of weekly thereafter. For sources with flow rate variability, flow rate shall be measured daily.

NR 856.31(1)(b)4. 4. Flow rate is measured by discharge from a horizontal pipe. Flow rate shall be measured on a daily basis for the first week and at a minimum of weekly thereafter.

NR 856.31(1)(b)5. 5. Estimate based upon time to fill a container of known volume. Flow rate shall be measured on a daily basis for the first week and at a minimum of weekly thereafter and if the flow is not continuous, hours of operation shall also be recorded.

NR 856.31(1)(b)6. 6. Alternative method and monitoring frequency that has been approved by the department.

NR 856.31(2) (2) The monthly volume of water withdrawn shall not include the volumes of water that are reused on the property or within the public water system.

NR 856.31(3) (3) Meters and measuring devices shall be maintained and calibrated as directed by the manufacturer.
