Michigan Administrative Code › Department - Environmental Quality › Oil, Gas & Minerals Division › Oil and Gas Operations › Part 11 - HYDROGEN SULFIDE MANAGEMENT › Section R. 324.1130 - Requirements for certain gathering lines, flow lines, and facility piping

Current through Vol. 24-12, July 15, 2024
Rule 1130.
(1) A
				  gathering line, installed after the effective date of these amendatory rules
				  carrying gas with more than 300 ppm hydrogen sulfide shall be subject to the
				  provisions for design, construction, testing, maintenance, and operation as
				  specified in administrative rules promulgated under Act No. 165 of the Public
				  Acts of 1969, as amended, being §483.151 et seq. of the Michigan Compiled
				  Laws.
(2) A flow line or facility
				  piping, carrying gas from a class I H2S well and which is subject to a maximum
				  working pressure in excess of 125 psig shall be subject to the provisions for
				  design, construction, testing, maintenance, and operation as specified in
				  administrative rules promulgated under Act No. 165 of the Public Acts of 1969,
				  as amended, being §483.151 et seq. of the Michigan Compiled
				  Laws.
(3) A person or a permittee
				  shall not install a flow line or gathering line, carrying gas from a class I
				  H2S or class II H2S well, or modify an existing flow line or gathering line to
				  serve additional class I H2S or class II H2S wells, unless all of the following
				  provisions are met:
(a) The person or
				  permittee shall calculate the 100 ppm radius of exposure, using either the
				  equation set forth in R 324.1102(c) or another dispersion model accepted by the
				  supervisor. The calculation shall be based upon the reasonably expected
				  concentration of hydrogen sulfide to be transported in the flow line or
				  gathering line, the maximum actual operating pressure, and the volume of gas
				  that could be released from the flow line or gathering line, accounting for any
				  automatic shut-in systems and blocking valves that will be utilized.
(b) If an existing structure used for public
				  or private occupancy, an existing area maintained for public recreation or the
				  edge of the traveled portion of an existing interstate, united states, or state
				  highway falls within the 100 ppm radius of exposure, the person or permittee
				  shall prepare a construction and operation plan that incorporates reasonable
				  measures to reduce the potential for public exposure to hydrogen sulfide from a
				  release that might occur. The construction and operation plan shall consider
				  appropriate construction standards, routing alternatives, monitoring equipment,
				  automatic controls for source shut-in, or other available engineering methods.
				  The person or permittee shall submit the construction and operation plan to,
				  and receive the approval of the supervisor or authorized representative of the
				  supervisor. The supervisor or authorized representative of the supervisor shall
				  have 30 days to approve the plan or to require modifications or additional
				  information.
(c) Repair and
				  maintenance of an existing flow line or gathering line are exempt from the
				  provisions of this subrule.
