If yes, Explain.
48. How does the POTW decide on which pollutants to limit in the permits? Monitor for? (for example: were only those pollutants
listed on the application limited; categorical parameters; NPDES Pollutants of Concern) Limits and pollutants based on IWS. A
effluent scan will be analyzed along with any other potential pollutants listed in IWS. CMSD will modify any permit limits
or pollutants in a modified permit based on analysis.
49. How does the POTW decide what the monitoring frequency should be for the various pollutants in industry permits? Explain.
Monitoring frequency is based on potential harm to POTW, pollutant scans and historical data.
