Current through Register Vol. 48, No. 38, September 20, 2024
a) Natural gas ("gas"),
as defined in Section 1.07 of "AN ACT to provide for the use of gas transmission
facilities by energy entities," (Ill. Rev. Stat. 1985, ch. 111 2/3, par. 571.07)
produced from wells in Illinois (including methane produced from the anaerobic
decomposition of municipal refuse) for use in Illinois and to be transported by a
gas public utility in Illinois must meet the following standards before the gas may
be placed into the utility's gas system. These standards do not apply to contracts
existing prior to the effective date of this Part.
1) The gas shall be commercially free from dust,
gum, gum forming constituents, and other solid and/or liquid matter.
2) The gas shall contain not more than 5 pounds of
water per one million standard cubic feet.
3) The gas shall not contain products in amounts
that will result in detrimental corrosion which would cause premature failure of
pipe, equipment or customer appliances over the normal life span of the pipe,
equipment, or appliances.
4) The gas
shall not contain more than .25 grain of hydrogen sulphide per 100 cubic feet and
not more than 1 grain of total sulfur per 100 cubic feet.
5) The gas shall not contain more than 3% by
volume of carbon dioxide.
6) The gas
shall not contain more than .5% by volume of oxygen.
7) The gas shall not contain more than 5 parts per
million by volume of halogenated hydrocarbons at any time.
8) The gas temperature shall be between the limits
of 40° and 110° Fahrenheit when delivered to the utility for
transportation.
9) The gas shall not
cause a reduction in the Btu content of the gas delivered to the utility's customers
unless the blended gases delivered to the individual customers are fully compensated
by a Btu correction factor stated in the utility's tariffs.
10) The transported gas must be interchangeable
with the utility's system gas so that the gas will burn in customers' equipment
without any adjustments to the customers' equipment being required.
Interchangeability will be determined in accordance with the American Gas
Association's Research Bulletin 36, "Interchangeability of Other Fuel Gases with
Natural Gases" (1952, Second Edition). No later amendment or edition is incorporated
by this subsection.
b) Tests
to determine the gas quality and containing gas quality are the responsibility of
the energy entity. Treatment of the gas to cause the gas to meet the standards of
this Part is the responsibility of the energy entity. Testing shall be subject to
monitoring by the utility.
