3. QUALITY (Continued)

 

(10) Toxic or Hazardous Substance: The gas shall not contain

any toxic or hazardous substance in concentrations which, in

the normal use of the gas, may be hazardous to health,

injurious to pipeline facilities, or be a limit to

merchantability or be contrary to applicable government

standards.

 

(11) Bacteria: The gas, including any associated liquids,

shall not contain any microbiological organism, active bacteria

or bacterial agent capable of causing or contributing to: (i)

injury to Transporter's pipelines, meters, regulators, or other

facilities and appliances through which such gas flows or (ii)

interference with the proper operation of the Transporter's

facilities. Microbiological organisms, include, but are not

limited to, sulfate reducing bacteria (SRB) and acid producing

bacteria (ACB). When bacteria or microbiological organisms are

considered a possibility, Shipper(s) desiring to Nominate such

gas, upon Transporter's request, shall cause such gas to be

tested for bacteria or bacterial agents utilizing the American

Petroleum Institute test method API-RP38 or other acceptable

test method as determined by both parties.

 

 

3.2 Gas Quality at Delivery Point(s). The gas delivered by Transporter

to Shipper at the Delivery Point shall be natural gas containing a gross

heating value of at least 985 Btus. Such gas shall be commercially free

of dust, gums, dirt, impurities and other solid matter and shall not

contain more than one-quarter grain hydrogen sulfide per one hundred

cubic feet as determined by using commercially available on-line analyses

and/or such analytical methods that are generally accepted in industry

practice; provided that Transporter may install and utilize a recording

hydrogen sulfide analyzer to monitor the gas at points at which it deems

such continuous monitoring to be desirable. The gas to be delivered

shall not contain more than five grains of total sulfur per one hundred

cubic feet, unless Transporter determines that there is a regulatory

requirement for gas to be odorized upstream of the Delivery Point, in

which case, the gas to be delivered shall not contain more than six

grains of total sulfur per one hundred cubic feet.
