N.P.D.E.S.
NPDES – NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM
Public Works Director Scharmen reports that the United States Environmental Protection Agency (USEPA), through regulations adopted in 1990 under the National Pollutant Discharge Elimination System (NPDES), required large, medium and small municipalities (including Indian Rocks Beach) to obtain permits for the operation and maintenance of their storm sewer systems where those systems discharge stormwater to the waters of the United States.
The regulations required municipalities to demonstrate adequate legal authority to prohibit illicit discharges to our storm sewer systems, provide maps of our storm sewers and outfalls, provide monitoring data showing the quality of runoff from local areas of various land use types, propose a management program that includes control measures to reduce pollutants in runoff, provide a program to detect and remove illicit discharges to our system, provide a program for monitoring compliance and the success of our programs, and provide an accounting of our fiscal resources available for carrying out this program.
In April of 1994, The City of Indian Rocks Beach participated along with other cities in Pinellas County in jointly applying for our N.P.D.E.S. permit through Pinellas County. The Cities, FDOT, and Pinellas County desire to continue to protect and promote the public health, safety and general welfare through the management of stormwater runoff, and to continue the existing relationships and responsibilities for control of discharge to municipal storm sewer systems (MS4) as outlined in 40 C.F.R., Section 122.26.
The City of Indian Rocks Beach made a conscious decision, rather than creating new jobs to track and investigate illicit discharges to our storm sewer system, to utilize existing staff to carry this out as part of their normal work. This is where you, as a resident can help.
All construction sites must be properly contained to avoid runoff.
This means that appropriate Best Management Practices (BMPs) should be used to protect the perimeter of the site, and any drainage or water body that could potentially be impacted. Here are some examples:
- Silt fencing (reinforced with chicken wire if needed), floating turbidity barriers
- Rock bags, filter fabric, filter socks for drains and inlets
- Hydroseed, sod to stabilize exposed areas
- Dewatering bags, flocking materials
- Gravel entrances to keep from tracking dirt out onto the roads
State Construction permits must be obtained for all sites larger than one acre.

Pesticide / Herbicide / Fertilizer Management
Public Works Director Scharmen reports that in maintaining home landscape, residents often do not realize the implications of their maintenance practices on the environment. Misuse of pesticides, herbicides and fertilizers can have a disastrous effect on groundwater resulting in contamination or run-offs into water supplies.
Pest problems in the lawn can be minimized by good cultural practices such as minimal fertilizing of your lawn; watering your lawn only when it shows signs of stress; keeping the blades on your lawn mower sharp and cutting only about one inch of the grass blade at any one cutting.
If spraying pesticides is necessary, it should be done when the least amount of damage will occur to plants and the natural predators of pests – early morning or late in the evening.
Disposal of pesticides/herbicides must be done properly and safely. The City of Indian Rocks Beach Public Works Department – Solid Waste Division asks that you do not place these items in your garbage. Please contact the Pinellas County Household Chemical Collection Center at 727-464-7565 where these products can be disposed of safely.
FAQ’s
Why are we inspecting for illicit discharges?
Who will do the inspecting and investigating?
Should you collect samples or other physical evidence?
What should I do if I find a suspected discharge?
How soon do I need to report it?
What is an illicit discharge? – How do I recognize one?
- This kind of discharge is sporadic; often occurring at night or on weekends, when the person involved thinks nobody is looking.
- This kind of discharge is not predictable, and as a result is hard to sample for gathering evidence.
- This kind of discharge could be toxic since it is often done by businesses trying to get rid of waste without having to do it properly. As a result, you really need to avoid coming in contact with it, or even breathing fumes if it is volatile.
- Often we need to make a quick decision to respond to this kind of event. If you see it actually occurring, it needs to be reported immediately so proper action can be taken. Later, after it has already happened, it may be too late; the damage may have already been done.
If I see deliberate dumping should I tell them to stop?
What are legal discharges?
- Flows from firefighting
- Landscape irrigation and lawn watering
