Abstract:
  This dataset is maintained and updated by the Dept. of Environmental Quality, Remediation Division - Hazardous Waste Site Cleanup Bureau, Petroleum Release Section in their portion of the "UST-Access" database. Requirements for database tracking of Leaking Underground Storage Tank data came from the Federal Office of Underground Storage Tanks in the 1980's. Since 1986, 4,198 releases have been reported. As of December 2005, there are 1,585 active petroleum releases and 2,613 resolved releases.
  LUST tracking is done in the same database as regulated UST sites (the UST-Access database). UST-Access is a project database serving only the underground storage tanks and leaking underground storage tanks programs. The system was developed using Microsoft Access 2.0 by EPA for use by the states and is no longer actively supported by EPA. The system was first implemented in 1997 and has been modified to handle Montana-specific data. Before phasing out its support of the system, EPA migrated the system to Access 97. Montana has continued to maintain, update, and enhance this system and it is currently in an Access 2003 format.
  A notification module stores status information for all underground storage tanks. A compliance module stores inspection and enforcement results. A LUST module stores information relating to releases. A Montana-developed permits module handles permit application, review and status information
  The goal of the Department of Environmental Quality Petroleum Release Section is to protect human health and the environment from petroleum and hazardous substance releases from storage tank systems, both underground and above ground. Meeting this goal requires definition of the extent and magnitude of the contamination and implementation of the necessary corrective action.
  Petroleum Release Section staff includes geologists, hydrogeologists, engineers, and environmental scientists who direct and oversee cleanup of petroleum releases. They are available as technical resources for tank owners and operators, local government officials, and the public to help respond to questions or concerns about tank leaks.
  Petroleum and hazardous substance releases can contaminate soil, groundwater and surface water, and may threaten or impact public and private drinking water supplies. In addition, harmful and potentially explosive hydrocarbon vapors can accumulate in confined spaces such as basements, crawl spaces and utility corridors. If a petroleum release occurs, the Petroleum Release Section assists and oversees the efforts of the facility owner or operator in assessing the potential threat to human health and the environment, and provides assistance with corrective action. The section works closely with the Petroleum Tank Release Compensation Board (PTRCB) which provides financial reimbursement of eligible corrective action cleanup costs to tank owners and operators.
  The Petroleum Release Section also administers the federal Leaking Underground Storage Tank (LUST) Trust Fund Program. This program conducts investigation and remediation activities at release sites that threaten human health and the environment where: (1) the release source is unknown or (2) the tank owner is insolvent or recalcitrant. The LUST Trust Program also conducts emergency response activities to mitigate immediate human health hazards such as petroleum-impacted drinking water supplies, and buildings impacted with petroleum vapors.
  State statutory authority for corrective actions is found in the Montana Underground Storage Tank Act, 75-11-501, MCA et seq. The Department's administrative rules are found in Title 17, Chapter 56 of the Administrative Rules of Montana (ARM). These rules include the requirements for release reporting, investigation, confirmation, abatement measures, and corrective action.
  The following functions are administered by the Petroleum Release Section:
  * receives and investigates reports of environmental storage tank releases;
  * assists local fire and health authorities in responding to the immediate threats resulting from contaminated drinking water supplies and explosive vapors created by releases;
  * requires, approves and oversees release investigation and remediation activities conducted by storage tank owners and operators;
  * reviews and recommends PTRCB reimbursement claims for completed investigation and remediation activities;
  * conducts final release site closure determinations at the conclusion of the remediation;
  * in the event the source of the release cannot be identified or the owner is recalcitrant, the LUST Trust Program utilizes federal LUST Trust funding to respond, investigate and remediate any health or environmental threats posed by the release.

Data Quality Information:

Completeness report:
  Only leak sites that are reported and verified by this department are represented in this dataset. For more detail on what specifically constitutes a leaking underground storage tank facility contact the DEQ Petroleum Release Section at 406-841-5055.
Horizontal Posistional Accuracy Report:
  Most coordinate locations were derived via map interpolation from USGS maps or address matching using Microsoft MapPoint. Coordinate accuracy varies, however, do not assume coordinate accuracy to be better than +/- one half mile without independent verification.
