2 LUST (Leaking Underground Storage Tank) Reports Utility company notification and associated Iowa Department of Natural Resources (IDNR) plume maps for each LUST site Certification by a P.E. in the state of Iowa, if PVC is to be used in a LUST site area (see attached form). 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. PLUMBING PLANS must include the following information: Interior plumbing (detail of service entry showing piping up to and including meter(s) and backflow prevention device(s) Meter location in meter pit (when required) Fire service (detail of riser, piping, etc.) Backflow prevention: Submit mechanical drawing showing the size, model, and location of the backflow prevention devices for both fire and domestic services, as required, and the applicable backflow preventon device cut/specification sheets. Refer to DMWW s Rules and Regulations for containment, Section 506. Must comply with City of Des Moines and State of Iowa Plumbing Codes. Completed Backflow Water Usage Inventory Form. Plumbing Permit Number: LOAD PROFILE must include the following information: Domestic (maximum & minimum anticipated flows expressed in gpm): Fire service (maximum anticipated flows expressed in gpm): Irrigation flows (maximum anticipated flows expressed in gpm): FIRE DEPARTMENT REVIEW FORM Submit the SIGNED form issued by the City of Des Moines Fire Prevention Engineer granting approval for the fire service (if your project includes a private fire service and is located inside Des Moines city limits). Contact Patrick Phelan SYSTEM DEVELOPMENT FEES - Required for all new taps inside the City of Des Moines and some areas outside the city limits, these fees are listed in the DMWW Rules & Regulations or they can be obtained by calling the DMWW Engineering Department for more information. System Development Fees for projects with both fire and domestic or any combination of multiple services will be the total of all services added together. Projects with metered combination fire and domestic services (master metered) shall be considered domestic services with fees being charged accordingly. ELECTRONIC COPY OF FINAL PLAN One (1) electronic site plan in a MicroStation compatible format correctly positioned on State Plane coordinates. ELECTRONIC COPY OF AS-BUILT RECORD DRAWING One (1) as-built record drawing of the service main in PDF format is to be submitted to the Water Works within 30 days of its construction and before the meter is set, unless otherwise approved by the Manager of Engineering Services.

3 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 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 a 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 Pre- App meetings OR you may call the Engineering Department at DMWW, 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 ( 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: ; Fax: ; [email protected] 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.

8 DMWW does not make 3 taps but 3 domestic connections can be teed off of the fire service for the building or property System Development Fees for projects with both fire and domestic services, or any combination of multiple services, will be the total of all of the System Development Fees added together System Development Fees for projects with metered combination fire and domestic services (master metered) shall be considered domestic services with fees being charged accordingly System Development Fees for subdivisions will be based upon the number and size of service stubs to be installed within the subdivision. All service stubs within subdivision will be considered domestic stubs unless sufficient evidence is provided to indicate otherwise The foregoing System Development Fees shall not apply to connections to a new water main constructed where no water main previously existed or a new water main is constructed to replace a private water main. The System Development Fees in such cases will be determined on a case by case basis and will be determined prior to construction of the new water main System Development Fees will be waived for the City of Des Moines and its agencies (Iowa Code ) If DMWW has record that a tap previously existed at a property, System Development Fees will not be required for replacement taps of equal size. Existing taps that are less than one inch in diameter and are being replaced with new one-inch taps will not require System Development Fees. Any replacement tap that is to be a larger size than the original tap, other than upsizing to a one-inch diameter tap, will require a fee that will be the difference between the fee for the new tap size and the fee for the original tap size.
