Please use the following checklist to ensure submittals are complete:
 DNR STANDARDS require that any water main/service lines installed in areas of groundwater contaminated by organic
compounds MUST be constructed of materials which do not allow permeation of these compounds into the drinking water
supply. It is the responsibility of the design engineer to do this research and to certify that appropriate materials have been
used.

LUST (Leaking Underground Storage Tank) sites
And the DMWW distribution system
What Is A Leaking Underground Storage Tank (LUST)?
An UST is a tank and associated piping with 10% or more of its volume below ground and which stored or
is storing a regulated substance. A LUST is a leaking underground storage tank.
A regulated substance is an element, compound or solution which, if released into the environment, may
present danger to the public health or welfare, or the environment and includes the following:
any petroleum or petroleum based substances (motor fuels, petroleum solvents, lubricants, used oil,
etc.);
any substance that exhibits hazardous characteristics defined in the Resource Conservation and Recovery Act (RCRA) hazardous waste regulations -orany substance regulated under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA).
How does a LUST site affect approval for new water service connections?
Section 8.1.2 of the Ten State Standards for Water Main Materials for permeation by organic compounds
requires where distribution systems are installed in areas of soil or groundwater contaminated by organic
compounds, a) pipe and joint materials which do not allow permeation of the organic compounds shall be
used and b) non-permeable materials shall be used for all portions of the system including pipe, joint materials, hydrant leads, and service connections. All new water services larger than 2” diameter that are
located within a 200’ radius of the plume within the LUST site will be required to be ductile iron pipe with
nitrile gaskets and all 1” and 2” services must be type K Copper unless you provide documentation that
the pipe being installed is outside of the contaminated area.
How Do I Get Information About A Specific LUST Site?
A list of LUST site numbers will be included in the Pre-App information packet provided by DMWW at PreApp meetings OR you may call the Engineering Department at DMWW, 323-6204. However, sites can be
added or removed at any time, it is your responsibility to research the DNR website to verify
this list. When researching LUST sites in the area of a project, you may also use the IDNR’s website
(https://programs.iowadnr.gov/tanks/pages/advanced.aspx).
Write down the LUST site number(s) for all of the circles which fall within your project area. Keep in mind
the center of the circle is tied to the address of the property where the LUST site exists, not necessarily to
the actual coordinates of the LUST tank. For this reason, the IDNR has chosen to use a 500’ radius circle
around the site to ensure the contamination plume is captured.
Provide the LUST site numbers to the IDNR Records Center to request Utility Company Notification and
associated plume maps for each LUST site. Contact information is as follows: Iowa DNR Records Center,
Iowa Department of Natural Resources, 502 E 9th Street, Des Moines, IA 50319; phone: 515-242-5818;
Fax: 515-281-8895; e-mail: dnr.records@dnr.iowa.gov
Once you receive the information back from the IDNR Records Center, you will need to submit to DMWW
for review. This information will give more exact locations for the contamination plume(s). The project
must be at least 200’ away from the edge of the contamination plume in order to use PVC pipe. If your
project site falls within a LUST site, you will be required to use DI pipe w/nitrile gaskets for services larger
than 2” or type K copper for 2” and smaller services. Any reference in the LUST documentation to a site
being “cleared for PVC pipe” does NOT mean new PVC pipe is allowed on the site, but rather that PVC water lines were either not present or not considered to be at-risk receptors when the LUST site was evaluated.
