BEFORE THE WELD COUNTY, COLORADO, PLANNING COMMISSION
RESOLUTION OF RECOMMENDATION TO THE BOARD OF COUNTY COMMISSIONERS
Moved by Bryant Gimlin that the following resolution be introduced for passage by the Weld County Planning
Commission with changes concerning buildings classed from R and above in the Uniform Building Code as
buildings not allowed within the 150 foot setback from Oil and Gas Production Facilities . Be it resolved by
the Weld County Planning Commission that the application for
ORDINANCE 89KK-AMENDMENTS TO WELD COUNTY ZONING ORDINANCE
PLANNER: Monica Daniels-Mika
REQUEST: The addition of Section 84, Amendments of Sections 31.5.5, 36.3.12, and 61.3 of the
Weld County Zoning Ordinance 89JJ
be recommended favorably to the Board of County Commissioners for the following reasons:
1. An amendment of the Weld County Ordinance 89 JJ, to add a new section 84 which states the following:
The Building Inspection Department shall withhold issuance of Building Permits if the use of the property does
not conform to the terms set forth in this Ordinance and, where made applicable by the terms set forth in any
other specified Weld County Ordinance, including, but not limited to, Ordinance No. 197 (PUD), Ordinance
No. 191 (MUD), Ordinance No. 119 (Subdivision), Ordinance No. 210 (WINDSOR SERVICE AREA ROAD
IMPACT FEE PROGRAM)and Ordinance No. 211 (SOUTHWEST WELD SERVICE AREA ROAD IMPACT
FEE PROGRAM).
2. An amendment to Section 31.5.5 and 36.3.12 which states:
No BUILDING or STRUCTURE classed R or above in the Uniform Building Code shall be constructed within
a 350 150 foot radius of any OIL AND GAS PRODUCTION FACILITIES. Any construction of a structure
classed R or above in the Uniform Building Code within a 350150 foot radius of OIL AND GAS PRODUCTION
FACILITIES shall require a variance from the terms of this Ordinance in accordance with Section 61.3
3. An amendment to Section 61.3 which states.
The Board of Adjustment has the power to hear and decide appeals for variance from the terms of the
Ordinance and the PUD Ordinance or MUD design standards as the PUD or MUD Ordinances are applied
to individual lots or parcels. Appeals for variance may be brought to the Board of Adjustment when, because
of special conditions relating to the subject land, a literal enforcement of these Ordinances would result in
unnecessary hardship to the appellant.
The Planning Commission has determined the inclusion of the attached language satisfies section 22.3.2.1-
22.3.2.3 of the Weld County Zoning Ordinance
22.3.2.1 That the existing Ordinance is in need of revision as proposed.
22.3.2.2 That the proposed amendment will be consistent with the future goals and needs of the COUNTY
as set out in the Weld County Comprehensive Plan
22.3.2.3 That the proposed amendment will be consistent with the overall intent of the Weld County Zoning
Ordinance

The Colorado Oil & Gas Association submits the following comments for the
case file in this matter:
1. A 150' radius does not preserve an adequate area around a wellhead to
allow for reasonable access and use of the surface to conduct workover,
frac'ing, refrac'ing or plugging and abandonment operations. A 200' radius
is the minimum distance to preserve adequate space to safely and efficiently
conduct such operations, including, of course, an adequate access corridor to
the wellsite. 150' may be adequate for separation of structures from tank
batteries and separators from a workspace standpoint, although 200' would be
preferable from a safety buffer perspective and would result in a consistent
setback rule.
2. The Colorado Oil and Gas Conservation Commission's "high density area"
rule (603.b) provides for a 350' setback from occupied structures for new
wells constructed in designated areas. This additional setback beyond the
safety buffer otherwise justified by the rulemaking record was a concession
by industry. COGA believes that should Weld County adopt a lesser setback
for encroaching high density surface development, it would provide grounds
for operators seeking a variance from the COGCC high density setback for
wells in Weld County. It is COGA's understanding, however, that individual
encroaching high density subdivision/PUD applicants could (and should) be
required to adhere to a 350' setback as a condition of approval. COGA
requests that this be made clear in the hearing record on the proposed
amendment.
Thank you for your consideration of these comments.

Subject: Change to Proposed Section 84
Lee had a minor change to our new proposed Section 84 to the Zoning Ordinance
which makes it read better. Also, Dave Sprague sent me an e-mail saying that
Ordinance 119 is the Building Code Ordinance, rather than Subdivision. So I
corrected that andadded both. Finally, Monica suggested we need a title, so
its on there too. Even though the notice didn't have these in there, I think
we can ask the Board to modify when it considers November 17, 1999. See the
attached. Bruce.

Oil and Gas issue:
Ken Wonstolen submitted the following comments via e-mail to the Clerk to the Board:
The Colorado Oil& Gas Association submits the following comments for the
case file in this matter:
1. A 150'radius does not preserve an adequate area around a wellhead to
allow for reasonable access and use of the surface to conduct workover,
frac'ing, refracting or plugging and abandonment operations. A 200'radius
is the minimum distance to preserve adequate space to safely and efficiently
conduct such operations, including, of course, an adequate access corridor to

2. The Colorado Oil and Gas Conservation Commission's "high density area"
rule (603.b)provides for a 350'setback from occupied structures for new
wells constructed in designated areas. This additional setback beyond the
safety buffer otherwise justified by the rulemaking record was a concession
by industry. COGA believes that should Weld County adopt a lesser setback
for encroaching high density surface development, it would provide grounds
for operators seeking a variance from the COGCC high density setback for
wells in Weld County. It is COCA's understanding, however, that individual
encroaching high density subdivision/PIID applicants could(and.should) be
required to adhere to a 350'setback as a condition of approval. COGA
requests that this be made clear in the hearing record on the proposed
amendment.
Thank you for your consideration of these comments.

Wonstolen also indicated to me that he wanted to make sure that greater setbacks would not be
precluded in a new PUD or subdivision since these would be minimums. 1 advised him that I
thought that if greater setbacks were needed to accommodate the oil and gas development , the
County would not be precluded from requiring greater setbacks in a final plan. (but it may be
appropriate to add language that says these are minimums and that new PUD, RE, or
Subdivision plats may require greater setbacks)..

SAFETY REGULATIONS
601. INTRODUCTION
The rules and regulations in this section are promulgated to protect the health, safety and welfare
of the
general public during the drilling, completion and operation of oil and gas wells and producing
facilities. They
do not apply to parties or requirements regulated under the Federal Occupational Safety and
Health Act of
1970 (See Rule 212.).
602. GENERAL
The training and action of employees, as well as proper location and operation of equipment is an
important
part of any safety program. While this section is general in nature, it is considered a basic part of
the
foundation of any safety program.
a. Employees shall be familiarized with these rules and regulations as provided herein as they
relate to
their function in their respective jobs. Each new employee should have their job outlined,
explained and
demonstrated.
b. Unsafe and potentially dangerous conditions as defined by these rules, should be reported
immediately by employees to the supervisor in charge and shall be remedied as soon as
practical. Any
accident involving injury to wellsite personnel or to a member of the general public which
requires
hospitalization, or significant damage to equipment or the wellsite shall be reported to the Oil
and Gas
Conservation Commission as soon as practicable, but in no event later than twenty-four (24)
hours after
the accident.
Where unsafe or potentially dangerous conditions exist, the owner or operator shall respond as
directed
by an agency with demonstrated authority to do so (such as sheriff, fire district director, etc.).
c. Vehicles of persons not involved in drilling, production, servicing, or seismic operations
shall be
located a minimum distance of one hundred (100) feet from the wellbore, or a distance equal
to the
height of the derrick or mast, whichever is greater. Equivalent safety measures shall be taken
where
terrain, location or other conditions do not permit this minimum distance requirements.
d. Existing wells are exempt from the provisions of these regulations as they relate to the
location of
the well.
e. Existing producing facilities shall be exempt from the provisions of these regulations with
respect to
minimum distance requirements and setbacks unless they are found by the Director to be
unsafe.
f Self-contained sanitary facilities shall be provided during drilling operations and at any
other similarly
staffed oil and gas operations facility.

b. High density area rules. A high density area shall be determined at the time the well is
permitted on a
well-by-well basis by calculating the number of occupied building units within the
seventy-two(72)acre
area defined by a one thousand (1000) foot radius from the wellhead or production facility.If
thirty-six
(36)or more actual or platted building units (as defined in the 100 Series rules) are within the
one
thousand (1000) foot radius or eighteen (18) or more building units are within any semi-circle
of the one
thousand (1000) foot radius(i.e., an average density of one (1) building unit per two(2)
acres), it shall
be deemed a high density area. If platted building units are used to determine the density, then
fifty
percent (50%) of said platted units shall have building units under construction or constructed.
If an
educational facility, assembly building, hospital, nursing home, board and care facility,:or jail
is located
within one thousand (1000)feet of a wellhead or production facility, it shall be considered a
high density
area. If a designated outside activity area is within one thousand (1000) feet of a wellhead or
production
facility the area may become high density upon application and determination by the COGCC
and shall
include a determination of the appropriate boundary for setback application,The following
rules shall
apply in high density areas:
(1)Provisions for encroaching development Il by virtue of subsequent future surface
development, an area becomes a high density area, subparagraphs (2), (3), (7) and (14)
shall not
apply to the operator.
. . .. . ... ............... ......... ......... ....
(2) Setbacks for wellheads. At the time of initial drilling of the well, the wellhead location
shall be
not less than three hundred fifty (350) feet from any building unit, educational facility,
assembly
building, hospital, nursing home, board and care facility, or)ail,-
(3) Setbacks for production equipment At,the time of initial installation, production tanks
and/or
associated on-site production equipment shalt be located not less than three hundred fifty
(350)
feet from any building unit, and, if requested by the local governmental designee,
production
tanks shall be located five hundred (500) feet from an educational facility,assembly
building,
hospital, nursing home,:board and care facility or jail. However, such five hundred:(500)
foot
setback shall be decreased to the maximum achievable setback if five hundred (50(i) feet
would
extend beyond the area on which the operator has a legal right to place or construct such
facilities Should the operator abject to such five hundred(500) foot setback for any
reason, a
variance hearing shall be conducted at the next regularly scheduled meeting of the
Commission,
subject to the notice requirements of Rule 507;
(4) A. Blowout preventer equipment ("BOPE") for high density area drilling operations.
Blowout
prevention equipment for drilling operations shall consist of(at a minimum):
i. Rig with kelley double ram with blind ram and pipe ram; •
annular preventer or a rotating head
ii. Rig without kelley double ram with blind ram and pipe ram
Mineral Management certification or Director approved training for blowout prevention
shall be
required for at least one (1) person at the wellsite during drilling operations.
B. BOPE testing for high density area drilling operations. Upon initial rig-up and at
least once every thirty (30) days during drilling operations thereafter, pressure
testing of the casing string and each component of the blowout prevention
equipment
shall be performed to seventy percent (70%) of working pressure or seventy percent
(70%) of the internal yield of casing, whichever is less. Pressure testing shall be
conducted and the documented results shall be retained by the operator for
inspection
by the Director for a period of one (1) year. In addition, flange connections shall be
tested on each rig-up, and blowout prevention equipment shall be tested whenever
the

east of
the guy line anchor.
(12) Berm construction. All newly installed or replaced berms in high density areas, in the
absence of remote impounding, shall be constructed around crude oil and condensate
storage
tanks and shall enclose an area sufficient to contain one hundred fifty percent (150%) of
the
largest single tank. No more than two (2) crude oil and condensate storage tanks shall be
located
within a single berm. Berms shall be inspected at regular intervals and containment
integrity
maintained. Refer to American Petroleum Institute Recommended Practices - D16.
(13) Tank specifications. All newly installed or replaced crude oil and condensate storage
tanks in
high density areas shall be designed, constructed, and maintained in accordance with
National
Fire Protection Association's latest edition (NFPA 30). The operator shall maintain writtej►
records verifying proper design, construction, and maintenance, and shall make these
records
available for inspection by the Director.
(14) Access roads. If a wellsite falls within a high density area at the time of construction,
all
leasehold roads shall be constructed to accommodate local emergency vehicle access
requirements, and shall be maintained in a reasonable condition.
(15) Well site cleared. Within ninety (90) days after a well is plugged and abandoned, the
well site
shall be cleared of all non-essential equipment, trash, and debris. For good cause shown, an
extension of time may be granted by the Director.
(I6) Identification of plugged and abandoned wells in high density areas. The operator
shall
identify the location of the wellbore with a permanent monument as specified in Rule
319.a.(5).
The operator shall also inscribe or imbed the well number and date of plugging upon the
permanent monument.
(17) Development from existing well pads. Where possible, operators shall provide for the
development of multiple reservoirs by drilling on existing pads or by multiple completions
or
commingling in existing wellbores (see Rule 322.). If any operator asserts it is not possible
to
comply with, or requests relief from, this requirement, the matter shall be set for hearing by
the
Commission and relief granted as appropriate.
c. Statewide rig floor safety valve requirements. When drilling or well servicing operations
are in
progress on a well where there is any indication the well will flow hydrocarbons, either
through prior
records or present conditions, there shall be on the rig floor a safety valve with connections
suitable for
use with each size and type of tool joint or coupling being used on the job.
d. Statewide static charge requirements. Rig substructure, derrick, or mast shall be designed
and
operated to prevent accumulation of static charge.
e. Statewide well servicing pressure check requirements. Prior to initiating well servicing
operations,
the well shall be checked for pressure and steps taken to remove pressure or operate safely
under
pressure before commencing operations.
f Statewide well control equipment and other safety requirements. Well control equipment
and other
safety requirements are:
(1) When there is any indication that a well will flow, either through prior records, present

hundred (500)
psi, and shall hold for fifteen (15) minutes without pressure loss in order for the casing
string to be
considered serviceable. Upon demand the operator shall provide to the Commission the
pressure
test evidence. Drilling operations shall not proceed until blowout prevention equipment is
tested
and found to be serviceable.
(7) If the blind rams are closed for any purpose except operational testing, the valves on
the
choke lines or relief lines below the blind rams should be opened prior to opening the rams
to
bleed off any pressure.

Lee thoughts-
Structure in WCZO currently encompasses:
STRUCTURE: Anything that is built, constructed, or erected, an edifice or building of any kind, or any
piece of work artificially built up or composed of parts joined together in some definite manner, but not
including fences or walls used as fences less than six (6) feet in height, poles, lines, cables or
distribution facilities of public utilities. Semi-trailers as defined in §42-1-102(70), CRS, situated as
TEMPORARY or permanent storage units, not safe or not operable or illegal to be used on public road
rights of way, which are not licensed, shall be considered 'STRUCTURES ' in accordance with this
definition, shall comply with requirements set forth in this Ordinance, including required zoning
SETBACKS and OFFSETS, and shall be installed in accordance with the requirements set forth in the
Weld County Building Code Ordinance.
BUILDING: Any STRUCTURE excluding fences, erected for shelter or enclosure of persons, animals, or
personal property of any kind.
There is not a definition in WCZO which defines the concept of building occupied by humans.
There is a concept in the 1SDS regulations of: "live , work or congregate" as structures which
require septic but they also use the term dwelling or occupied structure. This is tempered by the
ability to use toilet facilities if within 200' of the dwelling or occupied structure.
The UBC breaks down uses and it may work to use group and division classifications. All
Groups except S and U and ag exempt might work.
the OGCC provides (definition section in their rules): "BUILDING UNIT shall mean a building
or structure intended for human occupancy. A dwelling unit is
equal to one (1) building unit, every guest room in a hotel/motel is equal to one (1) building
unit, and
every five thousand (5,000) square feet of building floor area in commercial facilities, and
every fifteen
thousand (15,000) square feet of building floor area in warehouses, or other similar storage
facilities, is
equal to one (1) building unit".
The main purpose of this definition is to calculate whether an area is high density or not and does
not define human occupancy.
I agree that Burroughs point that "structure" is too broad and that oil and gas production facility
is too broad as well. I think excluding underground oil and gas production is OK as long as wells
are not excluded unless properly abandoned. I do not agree that 20' is ever adequate since there
is an access problem to the wellhead created by such a rule.
Burroughs indicates the problem is mostly found with tanks on adjoining property. The OGCC
requires tanks to be at least 2 '/z times the diameter or 350' from a surface property line so I am
not sure this is a real issue.

STATEMENT OF THE COLORADO OIL& GAS ASSOCIATION
NOVEMBER 16, 1999
RE: AN AMENDMENT TO SECTIONS 31.5.5 AND 36.3.12 OF WELD COUNTY
ORDINANCE#89-JJ,THE WELDCOUNTY ZONING ORDINANCE
COCA has submitted electronic comments in this matter regarding its concerns that the proposal
to reduce the setback for buildings and structures from existing oil and gas facilities to 150': (1)
does not provide sufficient working space consistent with mineral owners' right of reasonable
use; and(2) is inconsistent with the COGCC Rule 603(b)"high density area" setback standards.
CODA submits these additional written comments for the hearing record.
The Colorado Oil &Gas Conservation Commission conducted statewide rulemaking on safety
regulations on June 24, 1996. Among the issues examined was the appropriate setback from oil
and gas production facilities. Evidence was placed into the hearing record that:
(1) The Housing& Urban Development Administration safety standard for siting projects near
"hazardous facilities" requires a setback for possible exposure to persons of 180'
(2) A study conducting by EQE International for the American Petroleum Institute(Jan. 1995)
examined the safety margins associated with both radiant heat and blast overpressure effects
from the explosion of various hydrocarbons at different pressures. This study indicates that
for a wellhead blowout of a wet gas stream at 1000 psi, the distance to the hazard endpoint is
190'. This pressure is somewhat higher than a typical DJ Basin well, and the presence of
produced water in the gas stream will also reduce the hazard radius. However, it is
appropriate to establish safety margins on the basis of a"worst case scenario". Anecdotal
reports placed into the COGCC hearing record also indicated that tank explosions had
resulted in metal fragments being ejected 200' or more. (Note that when new production
facilities are placed in proximity to "high density areas"they must be at least 350' away from
occupied structures and must be designed to fail at the wall-to-ceiling seam so that metal
fragments are not ejected.)
Accordingly, COCA believes that a 200' minimum setback distance from oil and gas production
facilities is necessary from a public health, safety and welfare standpoint.
