(a) Applicability. Each operator who conducts operations as described in paragraph (1) of this subsection shall be subject to this section and shall provide safeguards to protect the general public from the harmful effects of hydrogen sulfide. This section applies to both intentional and accidental releases of hydrogen sulfide.
(1) Operations including drilling,
working over, producing, injecting, gathering, processing, transporting, and
storage of hydrocarbon fluids that are part of, or directly related to, field
production, transportation, and handling of hydrocarbon fluids that contain gas
in the system which has hydrogen sulfide as a constituent of the gas, to the
extent as specified in subsection (c) of this section, general
provisions.
(2) This section shall
not apply to:
(A) operations involving
processing oil, gas, or hydrocarbon fluids which are either an industrial
modification or products from industrial modification, such as refining,
petrochemical plants, or chemical plants;
(B) operations involving gathering, storing,
and transporting stabilized liquid hydrocarbons;
(C) operations where the concentration of
hydrogen sulfide in the system is less than 100 ppm.
(b) Definitions.
(1) Industrial modification--This term is
used to identify those operations related to refining, petrochemical plants,
and chemical plants. The term does not include field processing such as that
performed by gasoline plants and their associated gathering systems.
(2) Stabilized liquid hydrocarbon--The
product of a production operation in which the entrained gaseous hydrocarbons
have been removed to the degree that said liquid may be stored at atmospheric
conditions.
(3) Radius of
exposure--That radius constructed with the point of escape as its starting
point and its length calculated as provided for in subsection (c)(2) of this
section.
(4) Area of exposure--The
area within a circle constructed with the point of escape as its center and the
radius of exposure as its radius.
(5) Public area--A dwelling, place of
business, church, school, hospital, school bus stop, government building, a
public road, all or any portion of a park, city, town, village, or other
similar area that can expect to be populated.

or municipal street or road owned or maintained for public access or
use.
(7) Sulfide stress
cracking--The cracking phenomenon which is the result of corrosive action of
hydrogen sulfide on susceptible metals under stress.
(8) Facility modification--Any change in the
operation such as an increase in throughput, in excess of the designed
capacity, or any change that would increase the radius of exposure.
(9) Public infringement--This shall mean that
a public area and/or a public road, or both, has been established within an
area of exposure to the degree that such infringement would change the
applicable provisions of this rule to those operations responsible for creating
the area of exposure.
(10)
Potentially hazardous volume of hydrogen sulfide--A volume of hydrogen sulfide
gas of such concentration that:
(A) the 100
ppm radius of exposure is in excess of 50 feet and includes any part of a

determine the hydrogen sulfide concentration in the gaseous mixture in the
operation or system.
(A) Tests shall be made
in accordance with standards as set by ASTM Standard D-2385-66, or GPA Plant
Operation Test Manual C-1, GPA Publication 2265-68, or other methods approved
by the commission.
(B) Test of
vapor accumulation in storage tanks may be made with industry accepted
colormetric tubes.
(2)
For all operations subject to this section, the radius of exposure shall be
determined, except in the cases of storage tanks, by the following
Pasquill-Gifford equations, or by other methods that have been approved by the
commission.
(A) For determining the location
of the 100 ppm radius of exposure: x = [(1.589) (mole fraction
H2 S)(Q)] to the power of (.6258).
(B) For determining the location of the 500
ppm radius of exposure: x = [(0.4546) (mole fraction H2
S)(Q)] to the power of (.6258). Where x = radius of exposure in feet; Q =
maximum volume determined to be available for escape in cubic feet per day; H
2 S = mole fraction of hydrogen sulfide in the gaseous
mixture available for escape.
(3) The volume used as the escape rate in
determining the radius of exposure shall be that specified in subparagraph (A)
- (E) of this paragraph, as applicable.
(A)
The maximum daily volume rate of gas containing hydrogen sulfide handled by
that system element for which the radius of exposure is calculated.
(B) For existing gas wells, the current
adjusted open-flow rate, or the operator's estimate of the well's capacity to
flow against zero back-pressure at the wellhead shall be used.
(C) For new wells drilled in developed areas,
the escape rate shall be determined by using the current adjusted open-flow
rate of offset wells, or the field average current adjusted open-flow rate,
whichever is larger.
(D) The escape
rate used in determining the radius of exposure shall be corrected to standard
conditions of 14.65 pounds per square inch (psia) and 60 degrees
Fahrenheit.
(E) For intentional
releases from pipelines and pressurized vessels, the operator's estimate of the
volume and release rate based on the gas contained in the system elements to be
de-pressured.
(4) For
the drilling of a well in an area where insufficient data exists to calculate a
radius of exposure, but where hydrogen sulfide may be expected, then a 100 ppm
radius of exposure equal to 3,000 feet shall be assumed. A lesser-assumed
radius may be considered upon written request setting out the justification for
same.
(5) Storage tank provision:
storage tanks which are utilized as a part of a production operation, and which
are operated at or near atmospheric pressure, and where the vapor accumulation
has a hydrogen sulfide concentration in excess of 500 ppm, shall be subject to
the following.

radius of exposure shall be made for storage tanks as herein
described.
(B) A warning sign shall
be posted on or within 50 feet of the facility to alert the general public of
the potential danger.
(C) Fencing
as a security measure is required when storage tanks are located inside the
limits of a townsite or city, or where conditions cause the storage tanks to be
exposed to the public.

subject to this section, the operator shall comply with the following.
(I) A marker sign shall be installed at
public road crossings.
(II) Marker
signs shall be installed along the line, when it is located within a public
area or along a public road, at intervals frequent enough in the judgment of
the operator so as to provide warning to avoid the accidental rupturing of line
by excavation.
(III) The marker
sign shall contain sufficient information to establish the ownership and
existence of the line and shall indicate by the use of the words "Poison Gas"
that a potential danger exists. Markers installed in compliance with the
regulations of the federal Department of Transportation shall satisfy the
requirements of this provision. Marker signs installed prior to the effective
date of this section shall be acceptable provided they indicate the existence
of a potential hazard.
(iv) In satisfying the sign requirement of
clause (i) of this subparagraph, the following will be acceptable.
(I) Sign of sufficient size to be readable at
a reasonable distance from the facility.
(II) New signs constructed to satisfy this
section shall use the language of "Caution" and "Poison Gas" with a black and

acceptable if they indicate the existence of a potential hazard.
(B) Security provision.
(i) Unattended fixed surface facilities shall
be protected from public access when located within 1/4 mile of a dwelling,
place of business, hospital, school, church, government building, school bus
stop, public park, town, city, village, or similarly populated area. This
protection shall be provided by fencing and locking, or removal of pressure
gauges and plugging of valve opening, or other similar means. For the purpose
of this provision, surface pipeline shall not be considered as a fixed surface
facility.
(ii) For well sites,
fencing as a security measure is required when a well is located inside the
limits of a townsite or city, or where conditions cause the well to be exposed
to the public.
(iii) The fencing
provision will be considered satisfied where the fencing structure is a
deterrent to public access.
(C) Materials and equipment provision.
(i) For new construction or modification of
facilities (including materials and equipment to be used in drilling and
workover operations) completed or contemplated subsequent to the effective date
of this section, the metal components shall be those metals which have been
selected and manufactured so as to be resistant to hydrogen sulfide stress
cracking under the operating conditions for which their use is intended,
provided that they satisfy the requirements described in the latest editions of
NACE Standard MR-01-75 and API RP-14E, sections 1.7(c), 2.1(c), 4.7. The
handling and installation of materials and equipment used in hydrogen sulfide
service are to be performed in such a manner so as not to induce susceptibility
to sulfide stress cracking. Other materials which are nonsusceptible to sulfide
stress cracking, such as fiberglass and plastics, may be used in hydrogen
sulfide service provided such materials have been manufactured and inspected in
a manner which will satisfy the latest published, applicable industry standard,
specifications, or recommended practices.
(ii) Other materials and equipment (including
materials and equipment used in drilling and workover operations) which are not
included within the provision of clause (i) of this subparagraph may be used
for hydrogen sulfide service provided:
(I)
such materials and equipment are proved, as the result of advancements in
technology or as the result of control and knowledge of operating conditions
(such as temperature and moisture content), to be suitable for the use intended
and where such usage is technologically acceptable as good engineering
practice; and
(II) the commission
has approved the use of said materials and equipments for the specific uses
after written application.
(iii) Existing facilities (including
materials in present common usage for drilling and workover operations in
hydrogen sulfide areas) which are in operation prior to the effective date of
this section, and where there has been no failure of existing equipment
attributed to sulfide stress cracking, shall satisfy the requirements of this
section.
(iv) In the event of a
failure of any element of an existing system as the result of hydrogen sulfide
stress cracking, the compliance status of the system shall be determined by the
commission after the operator has submitted to the commission a detailed
written report on the failure.
(7) All operations subject to subsection (a)
of this section shall be subject to the additional control and equipment safety
provision, paragraph (8) of this subsection, and the contingency plan
provision, paragraph (9) of this subsection, if any of the following conditions

noncertificated leases or wells with a 100 ppm radius of exposure greater than
3,000 feet).
(H) In case of
extenuating circumstances, an operator may file a certificate of compliance
with an attached written explanation for those cases where waiver of 30-day
prior filing is requested. In such cases, the approval of the certificate of
compliance will constitute authority to proceed.
(I) The certificate of compliance shall be
prepared and executed by a party who, through training and experience, is
qualified to make such certification.
(J) The certificate of compliance will be in
effect until conditions are altered in a manner that would require amending the
"certificate." The operator shall notify the commission within 30 days
following cessation or abandonment of operations in a certificated
area.
(K) The certificate of
compliance required by the provisions of this order for an existing system are
due in the district office as soon as is reasonably possible, and no later than
September 1, 1976, and as applicable for new or modified operations.
(L) A certificate of compliance may cover a
single operation or multiple operations located in an area, a field, or a group
of fields within a commission district. The description of the type of
operation as indicated on the form must be sufficiently complete to the degree
that it is obvious what element of an operation is to be covered by the
certificate. All Railroad Commission identification numbers for each element of
the system must be shown on the certificate and must be identified as to the
type of operation.
(M) Certificates
are nontransferable, and a new operator of a system or any acquired element of
a system or operation shall be required to certificate that operation. Operator
of a certificated system shall notify the commission in writing when the system
or any operating part has been transferred to another operator. An amended
certificate shall be required should any change occur that would add or delete
a Railroad Commission identification number covered by the
certificate.
(N) Each operator
shall maintain a current master list of all his operations for which a
certificate of compliance is in effect and shall submit such list for
inspection upon request by the commission.
(2) Completion report provision.
