North Carolina Administrative Code › Title 15A - Environmental Quality › Chapter 02 - Environmental Management › Subchapter N - CRITERIA AND STANDARDS APPLICABLE TO UNDERGROUND STORAGE TANKS › Section .0900 - PERFORMANCE STANDARDS FOR UST SYSTEM OR UST SYSTEM COMPONENT INSTALLATION OR REPLACEMENT COMPLETED ON OR AFTER NOVEMBER 1, 2007 › Section 02N .0906 - SPILL BUCKETS

Current through Register Vol. 39, No. 2, July 15, 2024
(a) Spill buckets
				  shall be pre-fabricated with double-walled construction.
(b) Spill buckets shall be protected from
				  corrosion by being constructed of non-corroding materials.
(c) Spill buckets shall be designed,
				  constructed, installed, and maintained to prevent water infiltration.
(d) After installation but before
				  backfilling, the primary containment and interstitial space of the spill bucket
				  shall be tested in accordance with the manufacturer's written guidelines or a
				  code of practice developed by a nationally recognized association or
				  independent testing laboratory. Any change in vacuum during a vacuum test or
				  any change in liquid level in an interstitial space liquid reservoir beyond the
				  limits specified by the equipment manufacturer shall be considered a failure of
				  the integrity of the spill bucket. If the spill bucket fails a tightness test,
				  it shall be replaced or repaired by the manufacturer or the manufacturer's
				  authorized representative in accordance with the manufacturer's specifications.
				  Following any repair, the spill bucket shall be re-tested for tightness in
				  accordance with the manufacturers' written guidelines or a code of practice
				  developed by a nationally recognized association or independent testing
				  laboratory.
(e) Spill buckets that
				  are not monitored on an uninterrupted basis for releases using vacuum, pressure
				  or hydrostatic methods, shall be tested for tightness at installation and every
				  three years following installation. The primary containment and interstitial
				  space of the spill bucket shall be tested in accordance with:
(1) written requirements developed by the
				  manufacturer;
(2) a code of
				  practice developed by a nationally recognized association or independent
				  testing laboratory; or
(3)
				  requirements determined by the US Environmental Protection Agency or the
				  Division to be no less protective of human health and the environment than the
				  requirements listed in Subparagraph (1) and (2) of this Paragraph.
If the spill bucket fails a tightness test, it shall be
					 replaced and tested in accordance with Paragraphs (a) through (d) of this Rule
					 or repaired by the manufacturer or the manufacturer's authorized representative
					 in accordance with the manufacturer's specifications. Following any repair, the
					 spill bucket shall be re-tested for tightness in accordance with the
					 manufacturers' written guidelines or a code of practice developed by a
					 nationally recognized association or independent testing laboratory. The last
					 periodic tightness test record shall be maintained at the UST site or the tank
					 owner or operator's place of business and shall be available for
					 inspection.
