§6991h Study of Underground Storage Tanks

Title 42 › CHAPTER 82 — SOLID WASTE DISPOSAL › SUBCHAPTER IX — REGULATION OF UNDERGROUND STORAGE TANKS › § 6991h

Last updated Sep 23, 2026|Official source

Summary

The Administrator must finish a study of underground tanks that store regulated substances within 12 months after November 8, 1984, and must finish a study of all other underground tanks within 36 months after that date. The studies must look at tank age, how tanks are built and protected, where they are (including climate), soil and groundwater conditions, how these things affect the chance of leaks, and how effective and costly inventory, testing, and leak-detection systems are. By 36 months after November 8, 1984, the Administrator must also study the farm and heating-oil tanks named in section 6991(10)(A) and (B), estimate how many and where they are, and analyze possible releases. When the studies are done, the Administrator must send reports to the President and Congress with the results and with recommendations about whether these tanks should be covered by the earlier rules in this subchapter. If an owner or operator (but not a U.S. government agency, a State, or a local government) loses money because a tank was closed or stopped only for these studies, the Administrator must fairly repay those costs. Claims must be filed within 90 days after the closure or interruption. Payments come from funds Congress authorized under section 6916(g). The Administrator’s decision on such a claim is final for court review.
