EPA Image Welcome to the Water Locator Tool

This "Water Locator Tool" website is designed to help you locate your receiving water and to determine whether that waterbody is considered "impaired" under Section 303(d) of the Clean Water Act.

This information is needed to properly fill out your NOI. You will be using your facility address and/or facility lattitude-longitude to determine which waterbodies are closest to your facility location.

The Water Locator Tool leads you through a series of steps to help you answer the questions in your Notice of Intent (NOI) regarding your receiving water. The steps are summarized as follows:

  • STEP 1: Where is your facility located?
  • STEP 2: Which water(s) receive stormwater from my facility?
  • STEP 3: What impaired waters are within a 10-mile radius of my facility?



STEP 1: Where is your facility located?

Provide the information for either A or B below:

A. Enter your facility's address

Address:
Address 2:
City:
State:
Zip Code:
 
B. Enter your facility's latitude and longitude
If necessary, use a conversion tool to convert your latitude and longitude into decimals. For example, http://www.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html.Exit EPA Disclaimer
Latitude: ° N
(Decimals)
Longitude: ° W  
(Decimals)


STEP 2: Which water(s) receive stormwater from my facility?

To view an on-line map of waters in the vicinity of your facility, click on the “Go To: Window to My Environment” button. (Page will open in a new window).

Once the new window opens, follow these directions to locate potential waters that receive stormwater from your facility:

  • At bottom of map, click on "identify".
  • Select "streams" or "water bodies" from the drop down list next to "identify". Select "water bodies" to identify lakes, estuaries, etc.
  • Click on the blue stream or waterbody of interest in the map itself.
  • The name, if available, will display below the map. (Note: Some waterbody names are unavailable and a name will not be displayed.)
  • If the name is unavailable, you will need to consult another mapping resource, such as U.S.G.S. quadrangle maps.


Keep a list of the water(s) closest to your facility for Step 2. You should verify information obtained from EPA mapping systems by double-checking the information against local mapping resources (e.g., U.S.G.S. quadrangle maps, or other topographic maps) and/or knowledge of the property and landscape. In some cases, the closest water to your facility may not receive stormwater from your facility based on actual topographic conditions.

 


STEP 3: What impaired waters are within a 10 mile radius of my facility?

Using the same facility location as in Step 1, click on the “Retrieve List of Impaired Waterbodies” button. This will generate a report on the impaired waters near your facility.
