LUST Forms, Guidance, and Public Documents

The Leaking Underground Storage Tank program issues forms, guidance, and public documents to assist regulated entities and individuals on understanding and complying with District law.


Technical Guidance

The District of Columbia Underground Storage Tank Regulations include the District of Columbia Risk Based Corrective Action (DCRBCA) or Risk Based Decision Making (DCRBDM) process. This process can be used to develop site-specific risk based screening levels (RBSLs) and site-specific target levels (SSTLs) for remediation. This approach is supported by the United States Environmental Protection Agency. The DCRBDM process is detailed in the DCRBCA Guidance Document, June 2011. The applicability of the DCRBCA Guidance Document, June 2011 (see below), is detailed in the DCRBCA Guidance Cover Letter (see below). Table 5-11 of the DCRBCA was updated in February 2012. If updated Tier I and Tier II forms are needed, they are available upon request. To do so, please email [email protected] or call the UST Division at (202) 535-3322. DOEE plans to update DCRBCA in 2017 and incorporate the following as appendices:

  1. DOEE Petroleum Vapor Intrusion Summary
    A 5-page summary highlighting DOEE’s position, important recommendations and expectations regarding PVI mitigation and assessment. It  is intended to provide technical guidance for complying with the District’s Underground Storage Tank Regulations in Title 20 of the District of Columbia Municipal Regulations, Chapters 5500-7099. The UST Branch plans to incorporate this technical guidance into the next update of the District of Columbia Risk-Based Corrective Action Technical Guidance (DCRBCA) sometime in 2017. Read more in the DOEE PVI Summary Document (also attached below).
  1. EPA Petroleum Vapor Intrusion Guidance
    The Leaking Underground Storage Tank (LUST) Program, at the District of Columbia Department of Energy and Environment (DOEE), has adopted the U.S. EPA Petroleum Vapor Intrusion Technical Guide for LUST sites, June 2015. Please use this guidance for your reference when competing petroleum vapor intrusion (PVI) reports and considering mitigation measures (vapor barriers, etc.) for our review and approval. Read more in the EPA Petroleum Vapor Intrusion Technical Guide (also attached below).
  1. Soil Gas Sampling Guidance
    This Guidance was developed by DOEE, LUST Program to assist consultants with recommended best practices when collecting soil gas samples. The UST Branch is accepting comments on the Soil Gas Sampling Guide and the Vapor Intrusion Summary  and will consider incorporating those comments when the UST Branch releases the new UST Regulations and updated DCRBCA in 2017. Read more in the DOEE Soil Gas Sampling Guide (also attached below).
