Is Your Georgia Industrial Facility Ready for Indicator Monitoring?

Last year, Georgia Environmental Protection Division (EPD) released a new NPDES permit for stormwater discharges associated with industrial activity. The permit has several notable revisions including the new requirement for indicator monitoring for all permittees. Beginning in 2023, all permittees must monitor stormwater discharges for pH, Total Suspended Solids (TSS), and Chemical Oxygen Demand (COD) annually. In addition, certain sectors are required to monitor for polycyclic aromatic hydrocarbons (PAHs). The purpose of indicator monitoring is to provide a baseline and comparable understanding of industrial stormwater discharge quality. Indicator monitoring is required to be conducted within the first two quarters of 2023; therefore, the deadline for the first indicator monitoring event is June 30, 2023.

Another major change effective January 1, 2023 is that permittees are now required to submit all stormwater discharge monitoring data using NetDMR, EPA’s electronic DMR system. A DMR must be submitted within 45 days of each quarterly reporting period, even if no monitoring was conducted.

Environmental 360 can handle these new requirements for you. From collecting stormwater samples to submitting the results in NetDMR, we are here to help to keep your facility in compliance.
