N.M. Admin. Code § 19.15.11.12 - PROTECTION FROM HYDROGEN SULFIDE AT OIL PUMP STATIONS, PRODUCING WELLS, TANK BATTERIES AND ASSOCIATED PRODUCTION FACILITIES, PIPELINES, REFINERIES, GAS PLANTS AND COMPRESSOR STATIONS
A.
API standards. A person shall conduct operations at oil pump stations and
producing wells, tank batteries and associated production facilities,
refineries, gas plants and compressor stations involving a hydrogen sulfide
concentration of 100 ppm or greater with due consideration to the guidelines in
the API publication Recommended Practices for Oil and Gas Producing and Gas
Processing Plant Operations Involving Hydrogen Sulfide, RP-55, latest edition
or some other division-approved standard.
B. Security. A person shall protect well
sites and other unattended, fixed surface facilities involving a hydrogen
sulfide concentration of 100 ppm or greater from public access by fencing with
locking gates when the location is within 1/4 mile of a public area. For the
purposes of Subsection B of
19.15.11.12 NMAC, a surface
pipeline is not considered a fixed surface facility.
C. Wind direction indicators. Oil pump
stations, producing wells, tank batteries and associated production facilities,
pipelines, refineries, gas plants and compressor stations involving a hydrogen
sulfide concentration of 100 ppm or greater shall have equipment to indicate
wind direction. The person shall install wind direction equipment that is
visible from all principal working areas at all times.
D. Control equipment. When the 100 ppm radius
of exposure includes a public area, the following additional measures are
required.
(1) The person shall install and
maintain in good operating condition safety devices, such as automatic
shut-down devices, to prevent hydrogen sulfide's escape. Alternatively, the
person shall establish safety procedures to achieve the same purpose.
(2) A well shall possess a secondary means of
immediate well control through the use of an appropriate christmas tree or
downhole completion equipment. The equipment shall allow downhole accessibility
(reentry) under pressure for permanent well control.
E. Tanks or vessels. The person shall chain
each stair or ladder leading to the top of a tank or vessel containing 300 ppm
or more of hydrogen sulfide in the gaseous mixture or mark it to restrict
entry.
