NPDES (National Pollutant Discharge Elimination System) self-monitoring inspections are tied to overall storm water compliance through the NC General Permit “NCG010000” and are required to be conducted during normal business hours weekly and following rain events as required.
In North Carolina, inspections must meet both Water Resources and Land Quality requirements. This means a combined inspection that complies with the NPDES General Permit, NCG010000 as well as the Land Quality Self Inspections program, approved erosion control plan and any local government or municipality issued land development permits. Inspections are required by the NPDES permit to be performed once every seven days, or within 24 hours of 1 inch or more of rain in 24-hour period (whichever comes first), within normal business hours.
Written documentation of these inspections must remain at the construction site along with the permits and copy of the approved erosion and sediment control plan. It is the responsibility of the developer or other financially-responsible party to conduct or designate these inspections. If we are contracted to function as your designee to conduct these inspections, our staff of trained and certified inspectors with backgrounds from private and public sectors will conduct thorough regular and rain event inspections, then complete and issue written NPDES reports to the client.
During our site inspections we will identify potential and real pollutant sources, evaluate BMP performance, observe storm water outfalls during wet weather discharge, and confirm compliance with the permits. Pollution Monitoring Services inspectors will install an inspection box, digital rain gauge, and weekly log book on each project.
Reports are issued electronically to all of your staff designated to receive copies of the reports. We will place a hardcopy in the log book during the next inspection. All reports are also backed up electronically by Pollution Monitoring Services’ office.
We will evaluate each site and provide competitive pricing based on a review of each project’s approved plans, disturbed acreage or number of active lots.
