Per the PRC Potable Reuse Framework, IPR is planned delivery or discharge of reclaimed water to a. a potable water supply distribution system. b. an irrigation system. c. groundwater or surface waters. d. wetlands. 3. Per Florida Administrative Code (FAC) 62610, Reuse of Reclaimed Water and Land Application, what is the minimum system size for reclaimed water treatment facilities where reclaimed water is used for groundwater recharge or IPR? a. 0.1 million gallons per day (mgd) b. 0.5 mgd c. 1 mgd d. 3 mgd 4. Per FAC 62-610, discharges of reclaimed water to Class I waters shall be considered as being reuse for indirect potable purposes. What is the limit for total organic carbon (TOC) for these discharges? a. 1 mg/L monthly average, no single sample to exceed 3 mg/L b. 3 mg/L monthly average, no single sample to exceed 4 mg/L c. 3 mg/L monthly average, no single sample to exceed 5 mg/L d. 5 mg/L monthly average, no single sample to exceed 10 mg/L 5.

it’s possible to further treat reclaimed water to standards that make it safe for drinking? a. 20 percent b. 35 percent c. 40 percent d. 58 percent 6. Per the FDEP Jan. 14, 2021, presentation, Potable Reuse Rulemaking Public Workshop (Potable Reuse Rulemaking Workshop), potable reuse will require various means to protect drinking water quality that includes the collection system, wastewater treatment facilities, and advanced treated water. This is called a. advanced protection. b. discharge monitoring and control. c. multibarrier protection. d. overlapping controls. 7. Per the FDEP Potable Reuse Rulemaking Workshop, which potable reuse projects will be required to conduct pilot testing as detailed in the draft revisions to FAC 62-610? a. All potable reuse projects b. Projects for direct potable reuse only c. Projects using new or yet unapproved technologies d. Projects exceeding a capacity of 1 mgd 8. Per the FDEP Potable Reuse Rulemaking Workshop, draft revisions to FAC 62-610 include additional requirements for pretreatment/source control. Industrial or commercial businesses that discharge to a utility’s collection system must ensure all power-operated equipment associated with controlling or monitoring such discharges are connected to a continuous power source. They must also have in place a(n) a. early warning system for event detection. b. online connection to the utility receiving the waste. c. monthly equipment inspection program. d. permit from the U.S. Environmental Protection Agency. 9. Per the FAC 5/26/21 Coded Draft Rule 62555, Permitting, Construction, Operation, and Maintenance of Public Water Systems, prior to placing a potable reuse system into service, each wastewater facility and public water system participating in the potable reuse system shall submit to FDEP for approval a(n) a. emergency response plan. b. joint operations plan. c. risk management plan. d. water testing and analysis plan. 10. Per the FAC 5/26/21 Coded Draft Rule 62-610, Reuse of Reclaimed Water and Land Application, what must the pilot testing program include to
