Subpart 3173 - Requirements for Site Security and Production Handling
§ 3173.1 Definitions and acronyms.
(a) As used in this subpart, the term:
Access means the ability to:
(i)

Add liquids to or remove liquids from any tank or piping system, through a valve or combination
of valves or by moving liquids from one tank to another tank; or

(ii) Enter any component in a measuring system affecting the accuracy of the measurement of the
quality or quantity of the liquid being measured.
Appropriate valves means those valves that must be sealed during the production or sales phase (e.g., fill
lines, equalizer, overflow lines, sales lines, circulating lines, or drain lines).
Authorized representative (AR) has the same meaning as defined in 43 CFR 3160.0-5.
Business day means any day Monday through Friday, excluding Federal holidays.
Commingling and allocation approval (CAA) means a formal allocation agreement to combine production
from two or more sources (leases, unit PAs, CAs, or non-Federal or non-Indian properties) before that
product reaches an FMP.
Economically marginal property means a lease, unit PA, or CA that does not generate sufficient revenue
above operating costs, such that a prudent operator would opt to plug a well or shut-in the lease, unit
PA, or CA instead of making the investments needed to achieve non-commingled measurement of
production from that lease, unit PA, or CA. A lease, unit PA, or CA may be regarded as economically
marginal if the operator demonstrates that the expected revenue (net any associated operating
costs) generated from crude oil or natural gas production volumes on that property is not sufficient
to cover the nominal cost of the capital expenditures required to achieve measurement of noncommingled production of oil or gas from that property over a payout period of 18 months. A lease,
unit PA, or CA can also be considered economically marginal if the operator demonstrates that its
royalty net present value (RNPV), or the discounted value of the Federal or Indian royalties collected
on revenue earned from crude oil or natural gas production on the lease, unit PA, or CA, over the
expected life of the equipment that would need to be installed to achieve non-commingled
measurement volumes, is less than the capital cost of purchasing and installing this equipment.
Both the payout period and the RNPV are determined separately for each lease, unit PA, or CA oil or
gas FMP. Additionally, oil FMPs are evaluated using estimated revenue (net of taxes and operating
costs) from crude oil production, as defined in this section, while gas FMPs are evaluated using
estimated revenue (net of taxes and operating costs) from natural gas production, as defined in this
section.
Effectively sealed means the placement of a seal in such a manner that the sealed component cannot be
accessed, moved, or altered without breaking the seal.
Free water means the measured volume of water that is present in a container and that is not in
suspension in the contained liquid at observed temperature.

Requirements for Site Security and Production Handling

43 CFR 3173.1(a) “Land description”

Land description means a location surveyed in accordance with the U.S. Department of the Interior's
Manual of Surveying Instructions (2009), that includes the quarter-quarter section, section, township,
range, and principal meridian, or other authorized survey designation acceptable to the AO, such as
metes-and-bounds, or latitude and longitude.
Maximum ultimate economic recovery has the same meaning as defined in 43 CFR 3160.0-5.
Mishandling means failing to measure or account for removal of production from a facility.
Payout period means the time required, in months, for the cost of an investment in an oil or gas FMP for a
specific lease, unit PA, or CA to be covered by the nominal revenue earned from crude oil production,
for an oil FMP, or natural gas production, for a gas FMP, minus taxes, royalties, and any operating and
variable costs. The payout period is determined separately for each oil or gas FMP for a given lease,
unit PA, or CA.
Permanent measurement facility means all equipment constructed or installed and used on-site for 6
months or longer, for the purpose of determining the quantity, quality, or storage of production, and
which meets the definition of FMP under § 3170.3.
Piping means a tubular system (e.g., metallic, plastic, fiberglass, or rubber) used to move fluids (liquids and
gases).
Production phase means that event during which oil is delivered directly to or through production
equipment to the storage facilities and includes all operations at the facility other than those defined
by the sales phase.
Royalty Net Present Value (RNPV) means the net present value of all Federal or Indian royalties paid on
revenue earned from crude oil production or natural gas production from an oil or gas FMP for a
given lease, unit PA, or CA over the expected life of metering equipment that must be installed for
that lease, unit PA, or CA to achieve non-commingled measurement.
Sales phase means that event during which oil is removed from storage facilities for sale at an FMP.
Seal means a uniquely numbered device that completely secures either a valve or those components of a
measuring system that affect the quality or quantity of the oil being measured.
(b) As used in this subpart, the following additional acronyms apply:
BIA means the Bureau of Indian Affairs.
BMP means Best Management Practice.

§ 3173.2 Storage and sales facilities - seals.
(a) All lines entering or leaving any oil storage tank must have valves capable of being effectively sealed
during the production and sales phases unless otherwise provided under this subpart. During the
production phase, all appropriate valves that allow unmeasured production to be removed from storage
must be effectively sealed in the closed position. During any other phase (sales, water drain, or hot oiling),
and prior to taking the top tank gauge measurement, all appropriate valves that allow unmeasured
production to enter or leave the sales tank must be effectively sealed in the closed position (see Appendix
A to subpart 3173). Each unsealed or ineffectively sealed appropriate valve is a separate violation.

Requirements for Site Security and Production Handling

43 CFR 3173.2(b)

(b) Valves or combinations of valves and tanks that provide access to the production before it is measured
for sales are considered appropriate valves and are subject to the seal requirements of this subpart (see
Appendix A to subpart 3173). If there is more than one valve on a line from a tank, the valve closest to the
tank must be sealed. All appropriate valves must be in an operable condition and accurately reflect
whether the valve is open or closed.
(c) The following are not considered appropriate valves and are not subject to the sealing requirements of
this subpart:
(1) Valves on production equipment (e.g., separator, dehydrator, gun barrel, or wash tank);
(2) Valves on water tanks, provided that the possibility of access to production in the sales and storage
tanks does not exist through a common circulating, drain, overflow, or equalizer system;
(3) Valves on tanks that contain oil that has been determined by the AO or AR to be waste or slop oil;
(4) Sample cock valves used on piping or tanks with a Nominal Pipe Size of 1 inch or less in diameter;
(5) Fill-line valves during shipment when a single tank with a nominal capacity of 500 barrels (bbl) or
less is used for collecting marginal production of oil produced from a single well (i.e., production that
is less than 3 bbl per day). All other seal requirements of this subpart apply;
(6) Gas line valves used on piping with a Nominal Pipe Size of 1 inch or less used as tank bottom “roll”
lines, provided there is no access to the contents of the storage tank and the roll lines cannot be
used as equalizer lines;
(7) Valves on tank heating systems that use a fluid other than the contents of the storage tank (i.e.,
steam, water, or glycol);
(8) Valves used on piping with a Nominal Pipe Size of 1 inch or less connected directly to the pump body
or used on pump bleed off lines;
(9) Tank vent-line valves; and
(10) Sales, equalizer, or fill-line valves on systems where production may be removed only through
approved oil metering systems (e.g., LACT or CMS). However, any valve that allows access for
removing oil before it is measured through the metering system must be effectively sealed (see
Appendix A to subpart 3173).
(d) Tampering with any appropriate valve is prohibited. Tampering with an appropriate valve may result in an
assessment of civil penalties for knowingly or willfully preparing, maintaining, or submitting false,
inaccurate, or misleading reports, records, or written information under 30 U.S.C. 1719(d)(1) and 43 CFR
3163.2(f)(1), or knowingly or willfully taking, removing, transporting, using, or diverting oil or gas from a
lease site without valid legal authority under 30 U.S.C. 1719(d)(2) and 43 CFR 3163.2(f)(2), together with
any other remedies provided by law.

§ 3173.3 Oil measurement system components - seals.
(a) Components used for quantity or quality determination of oil must be effectively sealed to indicate
tampering, including, but not limited to, the following components of LACT meters (see § 3174.8(a)) and
CMSs (see § 3174.9(e)):
(1) Sample probe;
(2) Sampler volume control;

43 CFR 3173.3(a)(3)

(3) All valves on lines entering or leaving the sample container, excluding the safety pop-off valve (if so
equipped). Each valve must be sealed in the open or closed position, as appropriate;
(4) Meter assembly, including the counter head and meter head;
(5) Temperature averager;
(6) LACT meters or CMS;
(7) Back pressure valve pressure adjustment downstream of the meter;
(8) Any drain valves in the system;
(9) Manual-sampling valves (if so equipped);
(10) Valves on diverter lines larger than 1 inch in nominal diameter;
(11) Right-angle drive;
(12) Totalizer; and
(13) Prover connections.
(b) Each missing or ineffectively sealed component is a separate violation.

§ 3173.4 Federal seals.
(a) In addition to any INC issued for a seal violation, the AO or AR may place one or more Federal seals on any
appropriate valve, sealing device, or oil-metering-system component that does not comply with the
requirements in §§ 3173.2 and 3173.3 if the operator is not present, refuses to cooperate with the AO or
AR, or is unable to correct the noncompliance.
(b) The placement of a Federal seal does not constitute compliance with the requirements of §§ 3173.2 and
3173.3.
(c) A Federal seal may not be removed without the approval of the AO or AR.

§ 3173.5 Removing production from tanks for sale and transportation by truck.
(a) When a single truck load constitutes a completed sale, the driver must possess documentation containing
the information required in § 3174.12.
(b) When multiple truckloads are involved in a sale and the oil measurement method is based on the
difference between the opening and closing gauges, the driver of the last truck must possess the
documentation containing the information required in § 3174.12. All other drivers involved in the sale
must possess a trip log or manifest.
(c) After the seals have been broken, the purchaser or transporter is responsible for the entire contents of the
tank until it is resealed.

§ 3173.6 Water-draining operations.
When water is drained from a production storage tank, the operator, purchaser, or transporter, as appropriate, must
document the following information:
(a) Federal or Indian lease, unit PA, or CA number(s);

(h) Unique identifying number of each seal installed.

§ 3173.7 Hot oiling, clean-up, and completion operations.
(a) During hot oil, clean-up, or completion operations, or any other situation where the operator removes oil
from storage, temporarily uses it for operational purposes, and then returns it to storage on the same
lease, unit PA, or communitized area, the operator must document the following information:
(1) Federal or Indian lease, unit PA, or CA number(s);
(2) Tank location by land description;
(3) Unique tank number and nominal capacity;
(4) Date of the opening gauge;
(5) Opening gauge measurement (gauged manually or automatically) to the nearest 1⁄2 inch;
(6) Unique identifying number of each seal removed;
(7) Closing gauge measurement (gauged manually or automatically) to the nearest 1⁄2 inch;
(8) Unique identifying number of each seal installed;
(9) How the oil was used; and
(10) Where the oil was used (i.e., well or facility name and number).
(b) During hot oiling, line flushing, or completion operations or any other situation where the operator removes
production from storage for use on a different lease, unit PA, or communtized area, the production is
considered sold and must be measured in accordance with the applicable requirements of this subpart
and reported as sold to ONRR on the OGOR under 30 CFR part 1210 subpart C for the period covering the
production in question.

§ 3173.8 Report of theft or mishandling of production.
(a) No later than the next business day after discovery of an incident of apparent theft or mishandling of
production, the operator, purchaser, or transporter must report the incident to the AO. All oral reports must
be followed up with a written incident report within 10 business days of the oral report.
(b) The incident report must include the following information:
(1) Company name and name of the person reporting the incident;
(2) Lease, unit PA, or CA number, well or facility name and number, and FMP number, as appropriate;
(3) Land description of the facility location where the incident occurred;

43 CFR 3173.8(b)(4)

(4) The estimated volume of production removed;
(5) The manner in which access was obtained to the production or how the mishandling occurred;
(6) The name of the person who discovered the incident;
(7) The date and time of the discovery of the incident; and
(8) Whether the incident was reported to local law enforcement agencies and/or company security.

§ 3173.9 Required recordkeeping for inventory and seal records.
(a) The operator must perform an end-of-month inventory (gauged manually or automatically) that records:
TOV in storage (measured to the nearest 1⁄2 inch) subtracting free water, the volume not corrected for
temperature/S&W, and the volume as reported to ONRR on the OGOR;
(1) The end-of-month inventory must be completed within ± 3 days of the last day of the calendar month;
or
(2) The end of month inventory must be a calculated “end of month” inventory based on daily production
that takes place between two measured inventories that are not more than 31, nor fewer than 20,
days apart. The calculated monthly inventory is determined based on the following equation:
{[(X + Y − W)/Z1] * Z2} + X = A,
Where:
A = calculated end of month inventory;
W = first inventory measurement;
X = second inventory measurement;
Y = gross sales volume between the first and second inventory;
Z1 = number of actual days produced between the first and second inventory; and
Z2 = number of actual days produced between the second inventory and end of calendar month for which
the OGOR report is due.
For example: If the first inventory measurement performed on January 12 is 125 bbl, the second
inventory measurement performed on February 10 is 150 bbl, the gross sales volume between
the first and second inventory is 198 bbl, and February is the calendar month for which the
report is due. For purposes of this example, we assume February had 28 days and that the well
was non-producing for two of those days.
{[(150 bbl + 198 bbl − 125 bbl)/29 days] * 16 days} + 150 bbl = 273 bbl for the February end-ofmonth inventory.
(b) For each seal, the operator must maintain a record that includes:
(1) The unique identifying number of each seal and the valve or meter component on which the seal is or
was used;

(3) For valves, the position (open or closed) in which it was sealed; and
(4) The reason the seal was removed.

§ 3173.10 Form 3160-5, Sundry Notices and Reports on Wells.
(a) The operator must submit a Form 3160-5, Sundry Notices and Reports on Wells (Sundry Notice) for the
following:
(1) Site facility diagrams (see § 3173.11);
(2) Request for an FMP number (see § 3173.12);

lease, unit, or CA using WIS, unless the submitter:
(1) Is a small business, as defined by the U.S. Small Business Administration; and
(2) Does not have access to the Internet.

§ 3173.11 Site facility diagram.
(a) A site facility diagram is required for all facilities.
(b) Except for the requirement to submit a Form 3160-5, Sundry Notice, with the site facility diagram, no
format is prescribed for site facility diagrams. The diagram should be formatted to fit on an 81⁄2 x 11
sheet of paper, if possible, and must be legible and comprehensible to an individual with an ordinary
working knowledge of oil field operations (see Appendix A to subpart 3173). If more than one page is
required, each page must be numbered (in the format “N of X pages”).
(c) The diagram must:
(1) Reflect the position of the production and water recovery equipment, piping for oil, gas, and water,
and metering or other measuring systems in relation to each other, but need not be to scale;
(2) Commencing with the header, identify all of the equipment, including, but not limited to, the header,

(8) Clearly identify, on the diagram or as an attachment, all meters and measurement equipment.
Specifically identify all approved and assigned FMPs; and
(9) If the operator claims royalty-free use, clearly identify the equipment for which the operator claims
royalty-free use. The operator must either:
(i)

For each engine, motor, or major component (e.g., compressor, separator, dehydrator, heatertreater, or tank heater) powered by production from the lease, unit PA, or CA, state the volume
(oil or gas) consumed (per day or per month) and how the volume is determined; or

(ii) Measure the volume used, by meter or tank gauge.
(d) At facilities for which the BLM will assign an FMP number under § 3173.12, the operator must submit a
new site facility diagram as follows:

an FMP; or
(2) For a facility that is in service on or before January 17, 2017, and that has a site facility diagram on
file with the BLM that meets the minimum requirements of Onshore Oil and Gas Order 3, Site
Security, an amended site facility diagram meeting the requirements of this section is not due until
30 days after the existing facility is modified, a non-Federal facility located on a Federal lease or
federally approved unit or communitized area is constructed or modified, or there is a change in
operator.
(e) At facilities for which an FMP number is not required under § 3173.12 (e.g., facilities that dispose of
produced water), the operator must submit a new site facility diagram as follows:
(1) For new facilities in service after January 17, 2017, the new site facility diagram must be submitted
within 30 days after the facility becomes operational; or
(2) For a facility that is in service on or before January 17, 2017, and that has a site facility diagram on

Requirements for Site Security and Production Handling

43 CFR 3173.12

§ 3173.12 Applying for a facility measurement point.
(a)
(1) Unless otherwise approved, the FMP(s) for all Federal and Indian leases, unit PAs, or CAs must be
located within the boundaries of the lease, unit, or communitized area from which the production
originated and must measure only production from that lease, unit PA, or CA.
(2) Off-lease measurement or commingling and allocation of Federal or Indian production requires prior
approval (see 43 CFR 3162.7-2, 3162.7-3, 3173.15, 3173.16, 3173.24, and 3173.25).
(b) The BLM will not approve as an FMP a gas processing plant tailgate meter located off the lease, unit, or
communitized area.
(c) The operator must submit separate applications for approval of an FMP that measures oil produced from
a lease, unit PA, or CA, or under a CAA that complies with the requirements of this subpart, and an FMP
that measures gas produced from the same lease, unit PA, or CA, or under a CAA that complies with the
requirements of this subpart. This requirement applies even if the measurement equipment or facilities
are at the same location.
(d) For a permanent measurement facility that comes into service after January 17, 2017, the operator must
apply for approval of the FMP before any production leaves the permanent measurement facility. This
requirement does not apply to temporary measurement equipment used during well testing operations.
After timely submission and prior to approval of an FMP request, an operator must use the lease, unit PA,
or CA number for reporting production to ONRR, until the BLM assigns an FMP number, at which point the
operator must use the FMP number for all reporting to ONRR as set forth in § 3173.13.
(e) For a permanent measurement facility in service on or before January 17, 2017, the operator must apply
for BLM approval of an FMP within the time prescribed in this paragraph, based on the production level of
any one of the leases, unit PAs, or CAs, whether or not they are part of a CAA. The deadline to apply for an
FMP approval applies to both oil and gas measurement facilities measuring production from that lease,
unit PA, or CA.
(1) For a stand-alone lease, unit PA, or CA that produced 10,000 Mcf or more of gas per month or 100
bbl or more of oil per month, by January 17, 2018.
(2) For a stand-alone lease, unit PA, or CA that produced 1,500 Mcf or more, but less than 10,000 Mcf of
gas per month, or 10 bbl or more, but less than 100 bbl of oil per month, by January 17, 2019.
(3) For a stand-alone lease, unit PA, or CA that produced less than 1,500 Mcf of gas per month or less
than 10 bbl of oil per month, January 17, 2020.
(4) For a stand-alone lease, unit PA, or CA that has not produced for a year or more before January 17,
2017, the operator must apply for an FMP prior to the resumption of production.
(5) The production levels identified in paragraphs (e)(1) through (3) of this section should be calculated
using the average production of oil or gas over the 12 months preceding the effective date of this
section or over the period the lease, unit PA, or CA has been in production, whichever is shorter.
(6) If the operator of any facility covered by this section applies for an FMP approval by the deadline in
this paragraph, the operator may continue using the lease, unit PA, or CA number for reporting
production to ONRR, until the BLM's assigns an FMP number, at which point the operator must use
the FMP number for all reporting to ONRR as set forth in § 3173.13.

(7) If the operator fails to apply for an FMP approval by the deadline in this paragraph, the operator will
be subject to an INC and may also be subject to an assessment of a civil penalty under 43 CFR part
3160, subpart 3163, together with any other remedy available under applicable law or regulation.
(f) All requests for FMP approval must include the following:
(1) A complete Sundry Notice requesting approval of each FMP;
(2) The applicable Measurement Type Code specified in WIS;
(3) Information about the equipment used for oil and gas measurement, including, for:
(i)

“Gas measurement,” specify operator/purchaser/transporter unique station number, primary
element (meter tube) size or serial number, and type of secondary device (mechanical or
electronic);

(ii) “Oil measurement by tank gauge,” specify oil tank number or tank serial number and size in
barrels or gallons for all tanks associated with measurement at an FMP; and
(iii) “Oil measurement by LACT or CMS,” specify whether the equipment is LACT or CMS and the
associated oil tank number or tank serial number and size in barrels or gallons (there may be
more than one tank associated with an FMP);
(4) Where production from more than one well will flow to the requested FMP, list the API well numbers
associated with the FMP; and
(5) FMP location by land description.
(g) Request for approval of an FMP may be submitted concurrently with separate requests for off-lease
measurement and/or CAA.

§ 3173.13 Requirements for approved facility measurement points.
(a) For an existing facility in service on or before January 17, 2017, an operator must start using an FMP
number for reporting production to ONRR on its OGOR for the fourth production month after the BLM
assigns the FMP number(s), and every month thereafter. (For example, for a facility that is assigned an
FMP number on January 15, 2016, the effective date of the FMP is the May production report.) For a new
facility in service after January 17, 2017, an operator must start using an FMP number for reporting
production to ONRR on its OGOR for the first production month after the BLM assigns the FMP number(s),
and every month thereafter. (For example, for a facility that is assigned an FMP number on January 15,
2016, the effective date of the FMP is the February production report.)
(b)
(1) The operator must file a Sundry Notice that describes any changes or modifications made to the
FMP within 30 days after the change. This requirement does not apply to temporary modifications
(e.g., for maintenance purposes). These include any changes and modifications to the information
listed on an application submitted under § 3173.12.
(2) The description must include details such as the primary element, secondary element, LACT/CMS
meter, tank number(s), and wells or facilities using the FMP.
(3) The Sundry Notice must specify what was changed and the effective date, and include, if appropriate,
an amended site facility diagram (see § 3173.11).

§ 3173.14 Conditions for commingling and allocation approval (surface and downhole).
(a) Subject to the exceptions provided in paragraph (b) of this section, the BLM may grant a CAA only if the
proposed allocation method used for any such commingled measurement does not have the potential to
affect the determination of the total volume or quality of production on which royalty owed is determined
for all the Federal or Indian leases, unit PAs, or CAs which are proposed for commingling, and only if the
following criteria are met:
(1) The proposed commingling includes production from more than one:
(i)

Federal lease, unit PA, or CA, where each lease, unit PA, or CA proposed for commingling has
100 percent Federal mineral interest, the same fixed royalty rate and, and the same revenue
distribution;

(ii) Indian tribal lease, unit PA, or CA, where each lease, unit PA, or CA proposed for commingling is
wholly owned by the same tribe and has the same fixed royalty rate;
(iii) Federal unit PA or CA where each unit PA or CA proposed for commingling has the same
proportion of Federal interest, and which interest is subject to the same fixed royalty rate and
revenue distribution. (For example, the BLM could approve a commingling request under this
paragraph where an operator proposes to commingle two Federal CAs of mixed ownership and
both CAs are 50 percent Federal/50 percent private, so long as the Federal interests have the
same royalty rates and royalty distributions.); or
(iv) Indian unit PA or CA where each unit PA or CA proposed for commingling has the same
proportion of Indian interests, and which interest is held by the same tribe and has the same
fixed royalty rate; and
(2) The operator or operators provide a methodology acceptable to BLM for allocation among the
properties from which production is to be commingled (including a method for allocating produced
water), with a signed agreement if there is more than one operator;
(3) For each of the leases, unit PAs, or CAs proposed for inclusion in the CAA, the applicant
demonstrates to the AO that a lease, unit PA, or CA proposed for inclusion is producing in paying
quantities (or, in the case of Federal leases, capable of production in paying quantities) pending
approval of the CAA; and
(4) The FMP(s) for the proposed CAA measure production originating only from the leases, unit PAs, or
CAs in the CAA.
(b) The BLM may also approve a CAA in instances where the proposed commingling of production involves
production from Federal or Indian leases, unit PAs, or CAs that do not meet the criteria of paragraph (a)(1)
of this section (e.g., the commingling of leases, unit PAs, or CAs with different royalty rates or different
distributions of revenue, or where the commingling involves multiple mineral ownerships). In order to be
approved, a CAA under this subparagraph must meet the requirements of paragraphs (a)(2) through (4) of
this section and at least one of the following conditions:
(1) The Federal or Indian lease, unit PA, or CA meets the definition of an economically marginal property.
However, if the BLM determines that a Federal or Indian lease, unit PA, or CA included in a CAA
ceases to be an economically marginal property, then this condition is no longer met;

Requirements for Site Security and Production Handling

43 CFR 3173.14(b)(2)

(2) The average monthly production over the preceding 12 months for each Federal or Indian lease, unit
PA, or CA proposed for the CAA on an individual basis is less than 1,000 Mcf of gas per month, or
100 bbl of oil per month;
(3) A CAA that includes Indian leases, unit PAs, or CAs has been authorized under tribal law or otherwise
approved by a tribe;
(4) The CAA covers the downhole commingling of production from multiple formations that are covered
by separate leases, unit PAs, or CAs, where the BLM has determined that the proposed commingling
from those formations is an acceptable practice for the purpose of achieving maximum ultimate
economic recovery and resource conservation; or
(5) There are overriding considerations that indicate the BLM should approve a commingling application
in the public interest notwithstanding potential negative royalty impacts from the allocation method.
Such considerations could include topographic or other environmental considerations that make
non-commingled measurement physically impractical or undesirable, in view of where additional
measurement and related equipment necessary to achieve non-commingled measurement would
have to be located.

§ 3173.15 Applying for a commingling and allocation approval.
To apply for a CAA, the operator(s) must submit the following, if applicable, to the BLM office having jurisdiction
over the leases, unit PAs, or CAs from which production is proposed to be commingled:
(a) A completed Sundry Notice for approval of commingling and allocation (if off-lease measurement is a
feature of the commingling and allocation proposal, then a separate Sundry Notice under § 3173.23 is not
necessary as long as the information required under § 3173.23(b) through (e) and, where applicable, §
3173.23(f) through (i) is included as part of the request for approval of commingling and allocation);
(b) A completed Sundry Notice for approval of off-lease measurement under § 3173.23, if any of the
proposed FMPs are outside the boundaries of any of the leases, units, or CAs from which production
would be commingled (which may be included in the same Sundry Notice as the request for approval of
commingling and allocation), except as provided in paragraph (a) of this section;
(c) A proposed allocation agreement, including an allocation methodology (including allocation of produced
water), with an example of how the methodology is applied, signed by each operator of each of the leases,
unit PAs, or CAs from which production would be included in the CAA;
(d) A list of all Federal or Indian lease, unit PA, or CA numbers in the proposed CAA, specifying the type of
production (i.e., oil, gas, or both) for which commingling is requested;
(e) A topographic map or maps of appropriate scale showing the following:
(1) The boundaries of all the leases, units, unit PAs, or communitized areas whose production is
proposed to be commingled; and
(2) The location of existing or planned facilities and the relative location of all wellheads (including the
API number) and piping included in the CAA, and existing FMPs or FMPs proposed to be installed to
the extent known or anticipated;

Requirements for Site Security and Production Handling

43 CFR 3173.15(f)

(f) A surface use plan of operations (which may be included in the same Sundry Notice as the request for
approval of commingling and allocation) if new surface disturbance is proposed for the FMP and its
associated facilities are located on BLM-managed land within the boundaries of the lease, units, and
communitized areas from which production would be commingled;
(g) A right-of-way grant application (Standard Form 299), filed under 43 CFR part 2880, if the proposed FMP is
on a pipeline, or under 43 CFR part 2800, if the proposed FMP is a meter or storage tank. This requirement
applies only when new surface disturbance is proposed for the FMP, and its associated facilities are
located on BLM-managed land outside any of the leases, units, or communitized areas whose production
would be commingled;
(h) Written approval from the appropriate surface-management agency, if new surface disturbance is
proposed for the FMP and its associated facilities are located on Federal land managed by an agency
other than the BLM;
(i)

A right-of-way grant application for the proposed FMP, filed under 25 CFR part 169, with the appropriate
BIA office, if any of the proposed surface facilities are on Indian land outside the lease, unit, or
communitized area from which the production would be commingled;

(j)

Documentation demonstrating that each of the leases, unit PAs, or CAs proposed for inclusion in the CAA
is producing in paying quantities (or, in the case of Federal leases, is capable of production in paying
quantities) pending approval of the CAA; and

(k) All gas analyses, including Btu content (if the CAA request includes gas) and all oil gravities (if the CAA
request includes oil) for previous periods of production from the leases, units, unit PAs, or communitized
areas proposed for inclusion in the CAA, up to 6 years before the date of the application for approval of
the CAA. Gas analysis and oil gravity data is not needed if the CAA falls under § 3173.14(a)(1).

§ 3173.16 Existing commingling and allocation approvals.
Upon receipt of an operator's request for assignment of an FMP number to a facility associated with a CAA existing
on January 17, 2017, the AO will review the existing CAA and take the following action:
(a) The AO will grandfather the existing CAA and associated off-lease measurement, where applicable, if the
existing CAA meets one of the following conditions:
(1) The existing CAA involves downhole commingling that includes Federal or Indian leases, unit PAs, or
CAs; or
(2) The existing CAA is for surface commingling and the average production rate over the previous 12
months for each Federal or Indian lease, unit PA, and CA included in the CAA is:
(i)

Less than 1,000 Mcf per month for gas; or

(ii) Less than 100 bbl per month for oil.
(b) If the existing CAA does not meet the conditions of paragraphs (a)(1) or (a)(2) of this section, the AO will
review the CAA for consistency with the minimum standards and requirements for a CAA under §
3173.14.
(1) The AO will notify the operator in writing of any inconsistencies or deficiencies with an existing CAA.
The operator must correct any inconsistencies or deficiencies that the AO identifies, provide the
additional information that the AO has requested, or request an extension of time from the AO, within
43 CFR 3173.16(b)(1) (enhanced display)

43 CFR Part 3170 Subpart 3173 (up to date as of 3/27/2023)
Requirements for Site Security and Production Handling

43 CFR 3173.16(b)(2)

20 business days after receipt of the AO's notice. When the AO is satisfied that the operator has
corrected any inconsistencies or deficiencies, the AO will terminate the existing CAA and grant a new
CAA based on the operator's corrections.
(2) The AO may terminate the existing CAA and grant a new CAA with new or amended COAs to make
the approval consistent with the requirements under § 3173.14 in connection with approving the
requested FMP. If the operator appeals any COAs of the new CAA, the existing CAA approval will
continue in effect during the pendency of the appeal.
(3) If the existing CAA does not meet the standards and requirements of § 3173.14 and the operator
does not correct the deficiencies, the AO may terminate the existing CAA under § 3173.20 and deny
the request for an FMP number for the facility associated with the existing CAA.
(c) If the AO grants a new CAA to replace an existing CAA under paragraph (b) of this section, the new CAA is
effective on the first day of the month following its approval. Any new allocation percentages resulting
from the new CAA will apply from the effective date of the CAA forward.

§ 3173.17 Relationship of a commingling and allocation approval to royalty-free use of
production.
A CAA does not constitute approval of off-lease royalty-free use of production as fuel in facilities located at an FMP
approved under the CAA.

§ 3173.18 Modification of a commingling and allocation approval.
(a) A CAA must be modified when there is:
(1) A modification to the allocation agreement;
(2) Inclusion of additional leases, unit PAs, or CAs are proposed in the CAA; or
(3) Termination of or permanent production cessation from any of the leases, unit PAs, or CAs within the
CAA.
(b) To request a modification of a CAA, all operators must submit to the AO:
(1) A completed Sundry Notice describing the modification requested;
(2) A new allocation methodology, including an allocation methodology which includes allocation of
produced water and an example of how the methodology is applied, if appropriate; and
(3) Certification by each operator in the CAA that it agrees to the CAA modification.
(c) A change in operator does not trigger the need to modify a CAA.

§ 3173.19 Effective date of a commingling and allocation approval.
(a) If the BLM approves a CAA, the effective date of the CAA is the first day of the month following first
production through the FMPs for the CAA.
(b) If the BLM approves a modification, the effective date is the first day of the month following approval of
the modification.
(c) A CAA does not modify any of the terms of the leases, units, or CAs covered by the CAA.

§ 3173.20 Terminating a commingling and allocation approval.
(a) The AO may terminate a CAA for any reason, including, but not limited to, the following:
(1) Changes in technology, regulation, or BLM policy;
(2) Operator non-compliance with the terms or COAs of the CAA or this subpart; or
(3) The AO determines that a lease, unit, or CA subject to the CAA has terminated, or a unit PA subject to
the CAA has ceased production.
(b) If only one lease, unit PA, or CA remains subject to the CAA, the CAA terminates automatically.
(c) An operator may terminate its participation in a CAA by submitting a Sundry Notice to the BLM. The
Sundry Notice must identify the FMP(s) for the lease(s), unit PA(s), or CA(s) previously subject to the CAA.
Termination by one operator does not mean the CAA terminates as to all other participating operators, so
long as one of the other provisions of this subpart is met and the remaining operators submit a Sundry
Notice requesting a new CAA as outlined in paragraph (e) of this section.
(d) The AO will notify in writing all operators who are a party to the CAA of the effective date of the
termination and any inconsistencies or deficiencies with their CAA approval that serve as the reason(s)
for termination. The operator must correct any inconsistencies or deficiencies that the AO identifies,
provide the additional information that the AO has requested, or request an extension of time from the AO,
within 20 business days after receipt of the BLM's notice, or the CAA is terminated.
(e) If a CAA is terminated, each lease, unit PA, or CA that was included in the CAA may require a new FMP
number(s) or a new CAA. Operators will have 30 days to apply for a new FMP number (§ 3173.12) or CAA
(§ 3173.15), if applicable. The existing FMP number may be used for production reporting until a new
FMP number is assigned or CAA is approved.

§ 3173.21 Combining production downhole in certain circumstances.
(a)
(1) Combining production from a single well drilled into different hydrocarbon pools or geologic
formations (e.g., a directional well) underlying separate adjacent properties (whether Federal, Indian,
State, or private), where none of the hydrocarbon pools or geologic formations underlie or are
common to more than one of the respective properties, constitutes commingling for purposes of §§
3173.14 through 3173.20.
(2) If any of the hydrocarbon pools or geologic formations underlie or are common to more than one of
the properties, the operator must establish a unit PA (see 43 CFR part 3180) or CA (see 43 CFR
3105.2-1-3105.2-3), as applicable, rather than applying for a CAA.
(b) Combining production downhole from different geologic formations on the same lease, unit PA, or CA in a
single well requires approval of the AO (see 43 CFR 3162.3-2), but it is not considered commingling for
production accounting purposes.

§ 3173.22 Requirements for off-lease measurement.
The BLM will consider granting a request for off-lease measurement if the request:
(a) Involves only production from a single lease, unit PA, CA, or CAA;
(b) Provides for accurate production accountability;

(c) Is in the public interest (considering factors such as BMPs, topographic and environmental conditions that
make on-lease measurement physically impractical, and maximum ultimate economic recovery); and
(d) Occurs at an approved FMP. A request for approval of an FMP (see § 3173.12) may be filed concurrently
with the request for off-lease measurement.

§ 3173.23 Applying for off-lease measurement.
To apply for approval of off-lease measurement, the operator must submit the following to the BLM office having
jurisdiction over the leases, units, or communitized areas:
(a) A completed Sundry Notice;
(b) Justification for off-lease measurement (considering factors such as BMPs, topographic and
environmental issues, and maximum ultimate economic recovery);
(c) A topographic map or maps of appropriate scale showing the following:
(1) The boundary of the lease, unit, unit PA, or communitized area from which the production originates;
and
(2) The location of existing or planned facilities and the relative location of all wellheads (including the
API number for each well) and piping included in the off-lease measurement proposal, and existing
FMPs or FMPs proposed to be installed to the extent known or anticipated;
(d) The surface ownership of all land on which equipment is, or is proposed to be, located;
(e) If any of the proposed off-lease measurement facilities are located on non-federally owned surface, a
written concurrence signed by the owner(s) of the surface and the owner(s) of the measurement facilities,
including each owner's name, address, and telephone number, granting the BLM unrestricted access to
the off-lease measurement facility and the surface on which it is located, for the purpose of inspecting
any production, measurement, water handling, or transportation equipment located on the non-Federal
surface up to and including the FMP, and for otherwise verifying production accountability. If the
ownership of the non-Federal surface or of the measurement facility changes, the operator must obtain
and provide to the AO the written concurrence required under this paragraph from the new owner(s) within
30 days of the change in ownership;
(f) A right-of-way grant application (Standard Form 299), filed under 43 CFR part 2880, if the proposed offlease FMP is on a pipeline, or under 43 CFR part 2800, if the proposed off-lease FMP is a meter or storage
tank. This requirement applies only when new surface disturbance is proposed for the FMP and its
associated facilities are located on BLM-managed land;
(g) A right-of-way grant application, filed under 25 CFR part 169 with the appropriate BIA office, if any of the
proposed surface facilities are on Indian land outside the lease, unit, or communitized area from which
the production originated;
(h) Written approval from the appropriate surface-management agency, if new surface disturbance is
proposed for the FMP and its associated facilities are located on Federal land managed by an agency
other than the BLM;
(i)

An application for approval of off-lease royalty-free use (if required under applicable rules), if the operator
proposes to use production from the lease, unit, or CA as fuel at the off-lease measurement facility
without payment of royalty;

A statement that indicates whether the proposal includes all, or only a portion of, the production from the
lease, unit, or CA. (For example, gas, but not oil, could be proposed for off-lease measurement.) If the
proposal includes only a portion of the production, identify the FMP(s) where the remainder of the
production from the lease, unit, or CA is measured or is proposed to be measured; and

(k) If the operator is applying for an amendment of an existing approval of off-lease measurement, the
operator must submit a completed Sundry Notice required under paragraph (a) of this section, and
information required under paragraphs (b) through (j) of this section to the extent the information
previously submitted has changed.

§ 3173.24 Effective date of an off-lease measurement approval.
If the BLM approves off-lease measurement, the approval is effective on the date that the approval is issued, unless
the approval specifies a different effective date.

§ 3173.25 Existing approved off-lease measurement.
(a) Upon receipt of an operator's request for assignment of an FMP number to a facility associated with an
off-lease measurement approval existing on January 17, 2017, the AO will review the existing approved
off-lease measurement for consistency with the minimum standards and requirements for an off-lease
measurement approval under § 3173.22. The AO will notify the operator in writing of any inconsistencies
or deficiencies.
(b) The operator must correct any inconsistencies or deficiencies that the AO identifies, provide any
additional information the AO requests, or request an extension of time from the AO, within 20 business
days after receipt of the AO's notice. The extension request must explain the factors that will prevent the
operator from complying within 20 days and provide a timeframe under which the operator can comply.
(c) The AO may terminate the existing off-lease measurement approval and grant a new off-lease
measurement approval with new or amended COAs to make the approval consistent with the
requirements for off-lease measurement under § 3173.22 in connection with approving the requested
FMP. If the operator appeals the new off-lease measurement approval, the existing off-lease
measurement approval will continue in effect during the pendency of the appeal.
(d) If the existing off-lease measurement approval does not meet the standards and requirements of §
3173.22 and the operator does not correct the deficiencies, the AO may terminate the existing off-lease
measurement approval under § 3173.27 and deny the request for an FMP number for the facility
associated with the existing off-lease measurement approval.
(e) If the existing off-lease measurement approval under this section is consistent with the requirements
under § 3173.22, then that existing off-lease measurement is grandfathered and will be part of its FMP
approval.
(f) If the BLM grants a new off-lease measurement approval to replace an existing off-lease measurement
approval, the new approval is effective on the first day of the month following its approval.

§ 3173.26 Relationship of off-lease measurement approval to royalty-free use of production.
Approval of off-lease measurement does not constitute approval of off-lease royalty-free use of production as fuel
in facilities located at an FMP approved under the off-lease measurement approval.

§ 3173.27 Termination of off-lease measurement approval.
(a) The BLM may terminate off-lease measurement approval for any reason, including, but not limited to, the
following:
(1) Changes in technology, regulation, or BLM policy; or
(2) Operator non-compliance with the terms or conditions of approval of the off-lease measurement
approval or §§ 3173.22 through 3173.26.
(b) The BLM will notify the operator in writing of the effective date of the termination and any inconsistencies
or deficiencies with its off-lease measurement approval that serve as the reason(s) for termination. The
operator must correct any inconsistencies or deficiencies that the BLM identifies, provide any additional
information the AO requests, or request an extension of time from the AO within 20 business days after
receipt of the BLM's notice, or the off lease measurement approval terminates on the effective date.
(c) The operator may terminate the off-lease measurement by submitting a Sundry Notice to the BLM. The
Sundry Notice must identify the new FMP(s) for the lease(s), unit(s), or CA(s) previously subject to the offlease measurement approval.
(d) If off-lease measurement is terminated, each lease, unit PA, or CA that was subject to the off-lease
measurement approval may require a new FMP number(s) or a new off-lease measurement approval.
Operators will have 30 days to apply for a new FMP number or off-lease measurement approval,
whichever is applicable. The existing FMP number may be used for production reporting until a new FMP
number is assigned or off-lease measurement is approved.

§ 3173.28 Instances not constituting off-lease measurement, for which no approval is required.
(a) If the approved FMP is located on the well pad of a directionally or horizontally drilled well that produces
oil and gas from a lease, unit, or communitized area on which the well pad is not located, measurement at
the FMP does not constitute off-lease measurement. However, if the FMP is located off of the well pad,
regardless of distance, measurement at the FMP constitutes off-lease measurement, and BLM approval is
required under §§ 3173.22 through 3173.26.
(b) If a lease, unit, or CA consists of more than one separate tract whose boundaries are not contiguous (e.g.,
a single lease comprises two or more separate tracts), measurement of production at an FMP located on
one of the tracts is not considered to be off-lease measurement if:
(1) The production is moved from one tract within the same lease, unit, or communitized area to another
area of the lease, unit, or communitized area on which the FMP is located; and
(2) Production is not diverted during the movement between the tracts before the FMP, except for
production used royalty free.

§ 3173.29 Immediate assessments for certain violations.
Certain instances of noncompliance warrant the imposition of immediate assessments upon discovery, as
prescribed in the following table. Imposition of these assessments does not preclude other appropriate
enforcement actions:

Site Facility Diagrams and Sealing of Valves Introduction

Introduction
Appendix A is provided not as a requirement but solely as an example to aid operators, purchasers and
transporters in determining what valves are considered “appropriate valves” subject to the seal
requirements of this rule, and to aid in the preparation of facility diagrams. It is impossible to include
every type of equipment that could be used or situation that could occur in production activities. In
making the determination of what is an “appropriate valve,” the entire facility must be considered as
a whole, including the facility size, the equipment type, and the on-going activities at the facility.
