Stormwater Quality Management & MS4
Illicit Discharge Detection & Elimination
Illicit discharges are generally any discharge into a storm drain system that is not composed of entirely of storm water. Illicit discharges are a problem because storm water water generally flows to waterways without any additional treatment. Illegal discharges are defined in the City of Hobart municipal code (Chapter 152) as anything that causes or contributes to pollution.

Examples of improper physical connection to the storm sewer system include:
  • floor drain or household grey-water drain (laundry or sink drain) that is connected to a storm drain
  • a septic tank discharge pipe that is connected to a storm drain or drains directly into a waterway or an improper connection between a storm sewer and sanitary sewer

Improving Storm Water Quality
Residents can help alleviate storm water pollution in several ways:

  • Practice dry cleanup methods when cleaning your driveway or sidewalk. Use cat litter to soak up leaked oil, which can then be thrown away in the trash once dry.
  • Use phosphorus-free lawn fertilizers. Phosphorous runoff from lawns encourages algae growth in our lake.
  • Clean up immediately after your pets and throw the waste into the trash or in the toilet.
  • Dispose of lawn waste in compost piles and use a mulching mower.
  • Increase the amount of vegetated area in your yard. Consider directing downspouts away from paved surfaces to reduce polluted runoff.
  • Do not wash cars, RVs, or boats at home because the detergent laden water runs into storm drains and then into our waterways.Use a full or self service car wash when practical.

Storm Water Quality Management
Permits, Developer Instructions, and Post BMP's
The purpose of storm water management control is to reduce the pollutants from storm water runoff that originates from construction and post construction activities. The City of Hobart is required to have procedures for plan review of construction plans that consider potential water quality impacts.

The City of Hobart requires construction site operators to develop a storm water pollution prevention plan, or SWPPP, for their storm water discharges.A SWPPP is broader in scope than an erosion and sediment control plan or site plan.

The SWPPP requires post-construction storm water control measures to be submitted and approved as part of the site review construction plans. Post-Construction Narratives are required before completion of the project. The narrative describes the maintenance guidelines for all post-construction storm water quality measures to facilitate their proper long-term function.
