Has the Notice of Intent expired on your site?
This is a notice to developers, contractors and land owners.
Due to the slow economy many projects are taking much longer to complete than originally anticipated. This has caused certain land disturbing permits to expire. If a project is still under development, but the Notice of Intent (NOI) has expired, the site could face Notice of Violations and/or fines.

The NOI expires after a period of five years and should be renewed through the Indiana Department of Environmental Management. Go to http://www.in.gov/idem/5157.htm#owq_stormwater and choose Rule 5: Notice of Intent (NOI) - 47487 [PDF] [DOC]. Once you have the document, mark the renewal box at the top (The amendment box is marked in the case of a parcel of land already permitted that has changed ownership or responsibility. Please contact our office for more details concerning this type of change). The remaining information should be filled in using the original NOI and its information.

A current NOI must be posted in a readily accessible location on site in order for a site to be compliant with regulations.
Should you have any questions please contact our office at 812-256-2330, ext. 107. 

 

Indiana's efforts to clean up the waters in the State have been going on for a long while now. Beginning with the Stream Pollution Control Law of 1943, followed by the Clean Water Act of 1972, limits have been placed on the amount of pollutants that may be discharged into the waters of the State. These limits are set at levels protective of both the aquatic life in the waters which receive the discharge and protective of human health.

In 1990, the rules got a little stricter. EPA set up a basic stormwater control program for states to adopt, known as the National Pollutant Discharge Elimination System (NPDES) Permit Program. "Phase I" of this program regulated:

  • Construction activities that disturbed 5 or more acres.
  • Industrial activities depending on their pollutant potential
  • Municipal activities serving over 100,000 people

By 1999, the EPA was ready to implement "Phase II" of the NPDES program, and it published new regulations that covered:

  • Construction activities disturbing one (1) or more acres of land area.
  • Incentives for facilities to protect their operations from stormwater exposure.
  • Municipalities with less than 100,000 people.
They were really getting down to the nitty-gritty now, but the benefits to communities would be worth it:
  • Improved water quality
  • Safer waters for boating, swimming and fishing.
  • Reduced local drinking water treatment costs.
  • Fewer recreational beach closures.
  • A more desirable environment in which to live.

What's happening in Indiana as a result of Phase II?

Indiana established a Municipal Separate Storm Sewer System Program (MS4 Program), based on Phase II of the EPA's NPDES stormwater regulations. Under this program, communities are required to apply for and obtain a NPDES permit. The permit requires them to develop a stormwater management plan and to implement best management practices (stormwater pollution prevention measures).

The MS4 regulations apply to any entity that discharges into the waters of Indiana and that owns and/or operates a stormwater conveyance that is separate and not connected to a publicly owned treatment works or part of a combined sewer system (remember...stormwater does not normally go to a treatment plant). This covers not only cities and towns, but also public entities such as universities, military bases, and departments of transportation. By the way, a conveyance is just what the name says - a means of conveying or carrying water flow such as:

  • Roads with drainage systems
  • Municipal streets
  • Catch basins (curbside openings)
  • Curbs
  • Gutters
  • Ditches
  • Channels
  • Storm drains

What's happening in Clark County?

Well, the municipalities of Jeffersonville, Sellersburg, Clarksville, and Charlestown all fall under the new Phase II and MS4 regulations. In order to comply with program requirements, these communities will be:

  • Increasing public awareness of stormwater pollution.
  • Eliminating illegal connections and discharges to storm sewer systems.
  • Increasing sediment controls at construction sites.
  • Requiring controls in new development to remove pollutants from stormwater.
  • Improving pollution prevention from community facilities, such as maintenance garages, equipment areas, and work areas.
Details of the Phase II regulations can be found on the Indiana Department of Environmental Management (IDEM) - Office of Water Quality web site: http://www.state.in.us/idem/water/.

Indiana Stormwater Quality Manual

The Indiana Storm Water Quality Manual provides guidelines and specific storm water quality measures for controlling soil erosion; controlling and treating the nonpoint source pollution associated with sediment-laden runoff; and the management and treatment of pollutants associated with post-construction land uses.
