The provisions of the National Fire Protection Association,
				NFPA 54, ANSI Z223.1-2018 National Fuel Gas Code, 2018 edition, and NFPA 58,
				Liquefied Petroleum Gas Code, 2017 edition, published by the National Fire
				Protection Association, 1 Batterymarch Park, Quincy, MA 02169-7471, and all
				references contained therein, are hereby adopted by reference as the general
				requirements for transportation, storage, handling, and use of liquefied

Amend NFPA 54, ANSI Z223.1-2018 National Fuel Gas Code, 2018
				edition, as follows: Delete section 7.3.5.2 and insert in lieu thereof the
				following new section:
7.3.5.2
Gas piping underground, outside a
				building, shall not be in physical contact with any concrete. Where it is
				necessary to install piping that will extend through or under an exterior
				concrete slab for connection to a regulator or other part of the system, before
				entering a building, the gas piping shall be sleeved. The sleeve shall extend
				through the concrete and be sealed only at the end extending above grade to
				prevent the entrance of insects, debris, or moisture. All piping, fittings, and
				risers shall be protected against corrosion in accordance with NFPA 54,
				National Fuel Gas Code, 2018 edition, section 7.2.2.
Delete section 8.2.1 and insert in lieu thereof the following
				new section:
8.2.1
Leak checks using fuel gas (propane vapor)
				shall be permitted in piping systems that have been pressure-tested in
				accordance with 661-subrule 226.5(1).
Amend NFPA 58, Liquefied Petroleum Gas Code, 2017 edition, as
				follows:
Properties of LP-gases shall be determined in accordance with
				Annex B of NFPA 58.
Delete section 4.3.1 and insert in lieu thereof the following
				new section:
4.3.1
Stationary installations. Where a stationary
				installation utilizes a storage container of more than 2,000 gallons (7,570 L)
				of individual water capacity, or the aggregate water capacity of storage
				containers is more than 4,000 gallons (15,140 L) in water capacity, the
				installer shall submit plans (Liquid Propane Plan - DIVISION OF STATE FIRE
				MARSHAL) for such installation to the state fire marshal for review and
				approval. Installation shall not commence until written approval from the state
				fire marshal has been received. The local fire department [city or county where
				the tank(s) is located] shall be advised of each installation.
Delete section 5.2.3 and insert in lieu thereof the following
				new section:
5.2.3

(1) The cylinders shall be requalified in
			 accordance with DOT requirements.
(2) The cylinders shall be visually inspected
			 within 12 years of the date of manufacture and within every 5 years thereafter,
			 in accordance with 5.2.3.2 through 5.2.3.4.
5.2.3.2
Any cylinder that fails to meet one or
				more of the criteria in 5.2.3.4 shall not be refilled or continued in service

				accordance with the following:
(1) The
			 cylinder is checked for exposure to fire, dents, cuts, digs, gouges, and
			 corrosion according to CGA C-6-2013, Standard for Visual Inspection of Steel
			 Compressed Gas Cylinders, eleventh edition, except that 5.2.1.1 (1) of that
			 standard (which requires tare weight verification) shall not be part of the
			 required inspection criteria.
(2)
			 The cylinder protective collar (where utilized) and the foot ring are intact
			 and are firmly attached.
(3) The
			 cylinder is painted or coated to minimize corrosion.
(4) The cylinder pressure relief valve
			 indicates no visible damage, corrosion of operating components, or
			 obstructions.
(5) There is no
			 leakage from the cylinder or its appurtenances that is detectable without the
			 use of instruments.
(6) The
			 cylinder is installed on a firm foundation and is not in contact with the
			 soil.
(7) A cylinder that passes
			 the visual examination is marked with the month and year of the examination
			 followed by the letter E (e.g., "10-01E," indicating requalification in October
			 2001 by the external inspection method) and the requalifier identification
			 number (RIN) in accordance with the requalifying agency's permit issued by the
			 DOT.
(8) The results of the visual
			 inspection are documented, and a record of the inspection is retained for a
			 5-year period or until the cylinder is again requalified, whichever occurs
