Resources for UST State and Territorial Implementing Agencies
- Delivery prohibition
- State program approval
- Compliance resources
Delivery prohibition programs prohibit product delivery to underground storage tanks that have one or more compliance violations.
The state program approval (SPA) regulations set criteria for states to obtain the authority to operate in lieu of the federal program. State programs must be at least as stringent as EPA's.
EPA collects data from states and territories regarding UST performance measures. These data include information such as the number of active and closed tanks, releases confirmed, cleanups initiated and completed, facilities in compliance with UST requirements, and inspections.

- Energy-Water Nexus: Many Uncertainties Remain about National and Regional Effects of Increased Biofuel Production on Water Resources. GAO-10-116 November 2009 (PDF) (54 pp, 2.3 MB)
Although this report focuses on water resources affected by feedstock production and conversion to biofuels, it also acknowledges impacts to ground and surface water due to UST spills and releases (see pp 17-18, 34-35).
- Biofuels: Potential Effects and Challenges of Required Increases in Production and Use. GAO-09-446 August 2009 (PDF) (184 pp, 3.1 MB)
In this report, GAO investigated the effects of increased biofuels production on U.S. agriculture, environment, and greenhouse gas emissions; federal support for domestic biofuels production; and key challenges in meeting the Renewable Fuels Standard. Chapter 3 of the report discusses potential environmental impacts, including those attributed to leaking underground storage tanks (see pp 73-74). Chapter 7 also raises some issues associated with the storage of mid-level ethanol blends in legacy retail storage and dispensing equipment (see pp 120-123).
