(a) Installation
					 requirements.
(1) Category 1 requirements.
					 Piping in contact with the ground must be installed in accordance with the
					 following:
(i) Backfill. Piping that is
					 installed underground must use backfill material that is a non-corrosive,
					 porous, homogeneous substance and it must be placed completely around the
					 piping and compacted to ensure that the piping is fully and uniformly
					 supported. Backfill of at least six inches in depth must be placed underneath
					 the piping.
(ii) Burial depth.
					 Piping buried underground must be installed so that the top of the piping is at
					 least 18 inches below the surface of the ground. Should conditions make
					 compliance with this requirement impracticable, precautions must be taken to
					 prevent physical damage to the piping. It is not necessary to cover the portion
					 of the piping to which an access port is affixed.
(iii) Inspection of piping in contact with
					 the ground.
('a') Prior to covering,
					 enclosing, or placing piping in use, the piping must be inspected by a
					 qualified inspector in accordance with a consensus code, standard, or practice
					 developed by a nationally recognized association or independent testing
					 laboratory which meets the requirements of this subparagraph. This inspection
					 must include:
('1') weld breaks;
('2') punctures;
('3') scrapes of protective
					 coatings;
('4') cracks;
('5') corrosion;
('6') structural damage; and
('7') improper
					 installation.
('b')
					 Before being placed in service, the piping must be tested for tightness in
					 accordance with paragraph 2.3(d)(2) of this Part.
('c') All joints must be liquid-tight and
					 air-tight. If piping is found not to be tight or to be defective, all repairs
					 necessary to remedy the leaks or deficiencies in the piping must be performed
					 prior to the piping being placed in service.
('d') Upon completion of the tightness test
					 and inspection, the inspector must sign and date a statement certifying that
					 the system meets the requirements of this subdivision.
('e') The inspector's statement and records
					 of the tightness test and repairs must be kept for five years following the
					 date of installation and made part of the spill prevention
					 report.
(iv) Installation
					 Instructions. In addition to the above requirements, all piping in contact with
					 the ground must be installed in strict accordance with the manufacturer's
					 instructions and a consensus code, standard, or practice developed by a
					 nationally recognized association or independent testing laboratory consistent
					 with the standards of this subparagraph, such as API 1615. (See section
					 1.16  of this Part). This
					 includes repair of any damaged coatings prior to
					 backfilling.
