S. A 20V radius from the oil storage tanks may or may not include "Autumn Hills Lane" depending
on where the tanks are actually located. A 350' circle would include the road and major portions or
all of at least duplex lots 22, 23, 38, and 39. A�ti� -Y.,,9, (,V 1q��&(•) C- AP, Chi 1
6. Your development plan shows a lot of landscaping to th est of our tank1battery. As shown on
your map this appears not to give us access to our buildings and crude oil storage tanks. We have
our oil trucked offin large semi -truck tankers.
7. Your plan blocks all direct mad access which we currently have from our office, tank battery, and
water injection plant to the southern portion of our oil field.
8. Your plan shows a 100' circle around well 030-2 in parts of lots 71 and 72. It is not clear what
this circle designates.
9. It does not appear that the road widths and sharp corners would allow for oilfield equipment
access to wells 430-2 and 30-14.
I think that there are marry significant problems with your development plan 4 that it is unrealistic
to think these can be worked out in time for the late November final clearance from the City
Planning Department that you mentioned in our earlier conversations. We were brought into the
planning process at the last minute; the above continents are very preliminary, and we need more
time to examine and discuss your plans because this project will have a major long term impact on
our business. Additionally, we have a very complex surface use agreement which surely is important
to this development; I think the interpretation and implementation of this agreement should be
resolved among the parties before planning proceeds any further.
Very truly yours,

2. Drilling rigs reach about 145' above ground surface. They take 20+ truck loads to deliver. Trucks
have a maximum loaded weight of 120,000#, 20' width, 17' height, and 60' turning radius.
Additionally the derrick is 140' long and could hit obstructions beyond the truck turning radius. The
location size for spotting a drilling rig, digging a reserve pit, and allowing for trucks to erect the rig
and to turn around and deliver supplies is about 300' by 3001.
3. Many different types of vehicles are required to maintain and repair the existing oilfield
equipment. A truck & lowboy float loaded with a bulldozer can weigh 140,000# and be 42' long.
Maximum vehicle height would be 40' for a truck with an extended stinger or 16' for a 500 Bbl
portable frac tank. The frac tank is 12' wide; other trucks can be up to 10' wide.
Looking through the State Commission's safety regulations (section 600) I note the following:
1. Wellbores should be located the greater of 150' or 1.5 times the height of the derrick from any
occupied building, public road, major above ground utility line, or railroad. (For a 145' drilling rig
this distance would be 218 ; for a 107' service rig it would be 160'.). 1
2. Wellbores shall be at least 150' from a surface property line. Director can grant a wavier.
3. In a designated high density area:
A. The wellhead should be at least 350' from an occupied or permitted building.
B. Production tanks shall be at least 350' from buildings.
4. Tanks and fired vessels shall be at least 20W from residences, normally occupied buildings, or well
defined normally occupied outside areas.
5. All wells within 150' of residences, normally occupied buildings, or well defined normally
occupied outside areas must be equipped with a fail safe automatic control valve that will shut in the
well if the pressure suddenly rises or drops.
6. All pumps, pits, and producing facilities shall be adequately fenced to prevent access by
unauthorized persons when the equipment is easily accessible to the public and poses a physical or
health hazard.

A quick look at the development map you just supplied me shows the following items of concern:
1. There appear to be discrepancies in the locations of the involved oil wells on your map. Well #30-
2 may be located in the center of your proposed "Big Sandy Way" street. We should confirm where
the wells, the tank battery, and other oilfield equipment actually are on your development maps.
Also, these items should be clearly labeled
2. The locations of wells #30-2 and 30-14 are not compatible with your plan even if your plotted
well location is correct. The 150' radii would include the entire width of "Big Sandy Way" and
major portions of lots 70,71,72,126,127, and 128. The 21 8'radii would also include major portions
of lots 69, 73, 125, 129 and corners of tract "C" (future multi -family) and lot 75. The 350' radii
would include the above plus most or all of lots 68, 749 124, 130, up to an acre of tract "C", and
probably one or two acres of tract "A" (public natural area).
3. A 218' radius around well #30-1 would include almost half of lot 90 and corners of lots 89 and
92; it would also extend halfway across "North Pointe Drive," the south access road into the
development. A 350' radius would include the complete width of the road and most or all of lots
89, 90, 91, and 92.
4. The 350' radii around wells #30-11 and 30-13 would includI all of tract "G" (open space) and
about half of lot 102.

Re- Information gathered for October 27th Meeting j (y
Your Hoffman Planned Unit Development
Section 30-T8N-R68W Larimer County, Colorado
Dear Mr. Sell. -
Per our phone conversation on October 24th this letter includes information which WYting wants
to discuss at our subject meeting. Dale Walters gathered most of the background data, I made a few
phone calls and looked through the State Oil and Gas Commission regulations.
Whitings concerns are that high density development of the land will:
1. Be unsafe unless safety measures and adequate setbacks are maintained between oilfield
equipment and buildings, roads, and other occupied areas.
2. Interfere with oilfield operation due to limited access and well pad sizes and inability to secure
permits due to current and future Commission spacing regulations.
3. Lead to perennial conflict between the future homeowners and the oil company concerning noise,
traffic, dirt, spills, odor, visual impairment, etc. In addition, excavation in streets or yards may be
required to repair or install piping or for earthen pits. The purchasers of your homes will probably
not realize the consequences of living in an oilfield when they buy; later, they will blame the oil
company for the land use conflicts; by then the development will be complete and the developers
long gone.
Our inquiries about mobile well service equipment has turned up the following information:
1. Typical well service rigs have a mast height of up to 107' above ground surface. They weigh up
to 120,000# (52,000 # on the front wheels and 68,000# on the rear). Their highway length with mast
retracted is about 55', width is a little under 10', and height is just under 15'. Guy cables would need
to be anchored in a 127' by 127' square centered on the well.
