Hazardous Waste, New Construction and Active Aboveground Tank(s) Report
Last Updated: April 2026
Instructions: This Hazardous Waste, New Construction and Active Aboveground Storage Tank(s) Report is applicable for the 2026 and 2027 Multifamily Consolidated Request for Proposals (RFP)/2027 and 2028 Housing Tax Credit (HTC) funding rounds. Complete and submit this report, along with supporting documentation, as part of the application checklist in the Multifamily Customer Portal.
All applications proposing new construction projects must identify any active aboveground storage tank(s) of with a capacity of 500 gallons or more which contain hazardous waste that are present and located within 1,500 feet of each proposed site. Additionally, applicants must report each tank’s acceptable separation distance for blast over pressure, thermal radiation for people, and thermal radiation for the building.
If no active aboveground storage tanks are within the given proximity, supporting documentation must be included to demonstrate the claim.

Instructions
To identify active aboveground storage tank(s) within 1,500 feet from the site, visit and use the Minnesota Pollution Control Agency’s What’s in My Neighborhood tool and follow these steps:
1.	Enter the address of the proposed project sites in the search bar.
2.	Look for any red triangle ‘Tanks’ icons and yellow circle ‘Multiple Programs’ icons on the map for a general sense of tanks around the project site.
3.	Click on each ‘Tanks’ and ‘Multiple Programs’ icon to confirm whether the site(s) have aboveground storage tank(s).
4.	Determine which tank(s) or multiple programs sites with aboveground storage tanks are within 1,500 feet from the center of the project site.
a.	In the upper-right navigation, click the ruler icon to measure the proximity of the aboveground storage tank(s) to the project site:
b.	Click the ‘Measure distance’ icon.
c.	Change the units to Feet.
d.	Click on the project.
5.	Use a screen shot imaging tool to clearly illustrate the distance from the above-ground storage tank and the proposed project site. This must be completed for each active aboveground storage tank within 1,500 feet of the project site. Submit the screen shot as supporting documentation.
6.	Determine the status of the tank:
a.	Click the ‘Tanks’ or ‘Multiple Programs’ icon.
b.	Click on ‘Site details’ to view more information about the aboveground storage tank.
c.	Navigate to the ‘Activity overview’ tab to determine the status of the tank.
d.	If the status is inactive, no further action is needed.
7.	If the status is active, click ‘More Detail’ at the bottom of the webpage.
8.	Click on ‘Tank Data [Tank #]’ to view information specific to the tank(s) such as tank capacity, status, what is stored in the tank, etc. This information will be needed to complete Table 1 steps below.
9.	Click on Print, save and submit as supporting documentation.
To determine the acceptable separation distance (ASD) for blast over pressure, thermal radiation for people, and thermal radiation for the building, take the following steps:
1.	Navigate to the U.S. Department of Housing and Urban Development’s Acceptable Separation Distance Electronic Assessment Tool
2.	Enter the information from the tank data for each active aboveground storage tank and calculate the ASD.
3.	Use a screen shot imaging tool to capture the calculated results.
4.	Submit the screen shot as supporting documentation.
Report your findings by completing Table 1 below. When submitting the supporting documentation, clearly label each aboveground storage tank.

If the proposed project site is within the blast over pressure ASD of any active aboveground storage tank, describe the mitigation efforts to ensure the tenants and building will not be impacted by an explosion.
