Stormwater & Land Disturbance Information

Stormwater and Land Disturbance Information

The City of Eureka has developed this webpage to inform residents and businesses of the City of Eureka Stormwater Program. The Stormwater Program’s goal is to reduce the negative impacts that can occur with stormwater pollution.

What Is Stormwater?

Stormwater is water that flows across the land and into Eureka’s streams, lakes, ditches and canals. When it rains or snows, debris, sediment, bacteria, and nutrients on sidewalks, streets, and parking lots wash into gutters through storm drains and eventually flow untreated into the creeks.

Other sources of water include over-irrigation, automobile wash water, or any other activity that results in water flowing into the gutters or streams.

Debris and chemicals such as fertilizers, paint, oil, and other materials that are picked up by stormwater can be harmful to the environment and may end up in Eureka’s lakes and streams such as:
– Meramec River
– Flat Creek
– Fox Creek
– Small ponds and lakes within the City’s boundaries

What is the Eureka Stormwater Program?

Many large metropolitan areas (population over 10,000) throughout the United States are required to operate their storm sewer systems under a State permit. Under the Federal Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) Permit requires these cities to control the amount and the quality of the untreated waste being dumped into surface waterways through storm sewers. In 1999, the Environmental Protection Agency (EPA) enacted the Phase II Stormwater Rule that requires small-sized cities, like the City of Eureka, to also obtain a permit and to control the untreated stormwater that enters into the creeks, rivers, and lakes through storm sewers.

The Phase II Stormwater Rule:

(1) Is federally-mandated and unfunded.

(2) Requires the City of Eureka to obtain permit coverage and meet all requirements for stormwater discharges to State receiving waters.

(3) Is administered nationwide by the EPA and by MDNR within Missouri.

(4) Has financial penalties for non-compliance.

Minimum Control Measures

The current City Phase II Permit requires that six Minimum Control Measures (MCM) be continuously implemented. The City of Eureka must meet these MCM’s in order to report program success to the State. According to the terms of the approved Phase II Permit, the City is required to meet certain MCM deadlines through tasks known as measurable goals. A summary of each MCM is provided below.

MCM #1: Public Education and Outreach

(1) Distribute educational materials or conduct outreach activities about storm water discharge impacts on local water bodies.

(2) Inform businesses and the general public about the impacts of illegal discharge and improper waste disposal.

MCM #2: Public Participation/Involvement

Place notices in local newspapers informing the public about the opportunities for the public to participate in program development and implementation.

MCM #3: Illicit Discharge Detection and Elimination

(1) Decrease amount of illegal dumping and other unauthorized discharges from the MS4.

(2) Create outfall system map and plan to detect and remove discharges.

(3) Create a review process and City ordinance for regulation and enforcement.

MCM #4: Construction Site Stormwater Runoff Control

(1) Reduce the amount of stormwater pollution from construction sites (sediment, building materials, oil, etc.).

(2) Create a review process and City ordinance for regulation and enforcement.

(3) Require, review, inspect, and enforce proper management practices and material disposal on construction sites.

MCM #5: Post-Construction Stormwater Management

(1) Decrease the amount of pollutants and peak quantity of stormwater leaving newly developed areas.

(2) Create a review process and City ordinance for regulation and enforcement.

(3) Require, review, inspect, and enforce proper methods for detaining/improving quality of water for sites.

MCM #6: Pollution Prevention/Good Housekeeping for Municipal Operations

(1) Reduce pollutants from municipal parking lots, streets, open spaces, etc., and operations facilities (i.e. salting/sanding/fertilizing).

(2) Inventory all City storm drainage facilities and outfalls.

(3) Develop program to train employees.

Stormwater Facts

Did You Know…

Unlike wastewater, stormwater is not treated at a sewage treatment plant. Anything dumped or placed on the ground is carried away by stormwater runoff and will end up in the City’s storm drains which discharge into our ditches, reservoirs, creeks, ponds, lakes and rivers.

Leaves, grass clippings and other yard wastes cause elevated levels of nutrients in our waterways and is harmful to fish and aquatic organisms. Properly disposing of these materials will prevent them from entering the City’s storm drains. Place them in your compost pile for use next spring in your vegetable and flower gardens.

Pet waste left on the ground contains high concentrations of bacteria and can be carried by stormwater runoff, which is harmful to fish and aquatic organisms. Bag it up and place it in the garbage or flush it.

Salt and other chemicals to remove snow and ice is carried by stormwater runoff and increases nutrient levels, which is harmful to fish, aquatic organisms and other animals who depend on clean water for their health.

Applying lawn and garden chemicals sparingly and according to the directions not only saves you money, but helps protect our ditches, reservoirs, creeks, ponds, lakes and rivers. Over application adds to the nutrient levels in these waterways and is harmful to fish and other animals who depend on clean water for their health.

How You Can Help

– If you wash your vehicle at home, make sure no soaps or oils enter the storm drain system. Either wash your car without soap, pull it onto the lawn, or take it to a commercial car wash.
– Keep vehicles in good repair so that they don’t leak any fluids.
– Store all materials (oils, paint, household cleaners, fertilizers, etc.) in proper containers and in such a way that they cannot leak and be washed into the storm drainage system.
– Recycle or properly dispose of all materials.
– Sweep walkways, driveways and other outside surfaces, rather than hosing them.
– Use native plants in low-maintenance landscaping to reduce fertilizer and water.
– Eliminate the use of pesticides in your garden and around your home.
– Cover any exposed soil, especially while working on landscape projects.
– Preserve streamside vegetation.
– Pick up after your pets, both in the park and in your own backyard.
– Walk, ride your bike, take the bus or carpool.
