13. Describe whether ANSI/NSF 61 certification exists for the proposed treatment process/unit (except conventional and direct filtration plants). 14. Describe all chemicals that will be used for the proposed treatment processes. State whether these chemicals meet the ANSI/NSF 60 standard. 15. Identify the specific rules applicable to this review (e.g., R309-525, R309-530-8). Briefly describe the issues related to specific rule requirements. 16. If applicable, address compliance” concerns. Describe whether the treated water “simultaneous and/or waste stream from the proposed treatment facility may result in unintended consequences in the distribution system or the environment. [For example, the finished water produced from a reverse osmosis (RO) WTP may cause corrosion or lead/copper MCL exceedance in the distribution system; the brine of RO reject stream may not be legally disposed.] 17. Plan Approval (PA) letters for surface water WTPs should include the following information: a. Specify quality data” that are required to show WTP performance before issuing “water a WTP OP. Customize the quality data” item in the generic Operating Permit (OP) “water checklist to include the following information: Specific parameters to be sampled (e.g., turbidity, minimum chlorine residual) Sampling locations (e.g., raw after filters, after clear well) Frequency of sampling (e.g., the highest turbidity reading at 4-hour intervals, daily turbidity sample at least one day apart for very small water systems) Number of before and sample sets (e.g., 4 sets of before & after turbidity data, 7 days of 4-hour turbidity readings) b. Obtain the preliminary monitoring and reporting information from the Rules Section. Provide it to PWS (include with PA) for informational purposes. [The preliminary monitoring and reporting information is important if a WTP project includes PLC and SCADA programming prior to completion of the project or requesting OP.] 18. The Operating Permit (OP) letter must include the monitoring schedule follow-up paragraph. 19. Consult with the Rules Section staff. Surface water monthly report & customized report template for each WTP Disinfection WQ data review & WTP monitoring schedule If needed, surface water technical assistance and federal regulations
