5) The pumping rate of this well shall not exceed 15 GPM.
.--,-,.
The average annual amount of ground water to be appropriated shall not exceed 4 acre-feet.
/) Production is limited to the Laramie Fox Hills aquifer which is located 570 feet below land surface and extends to a depth of 860 feet. Plain
casing must be installed and grouted to prevent the withdrawal of ground water from other aquifers and the movement of ground water
between aquifers.
8) The depth to the top of the Laramie-Fox Hills aquifer is approximate. To ensure the exclusion of poor quality water from zones immediately
above the aquifer,plain casing and grout shall extend through the lowermost coal and/or carbonaceous shale that overlies the Laramie sand
portion of the aquifer.
9) The entire length of the hole shall be geophysically logged as required by Rule 9 of the Statewide Nontributary Ground Water Rules prior to
installing casing.
10) The owner shall mark the well in a conspicuous place with well permit number(s),name of the aquifer,and court case number(s)as
appropriate. The owner shall take necessary means and precautions to preserve these markings.
11) A totalizing flow meter must be installed on this well and maintained in good working order. Permanent records of all diversions must be
maintained by the well owner(recorded at least annually)and submitted to the Division Engineer upon request.
12) This well shall be constructed at least 600 feet from any existing well,completed in the same aquifer,that is not owned by the applicant.
13) This well shall be constructed not more than 200 feet from the location specified on this permit.
14) Pursuant to CRS 37-90-137(9)(b)and the Denver Basin Rules,no more than 98%of the nontributary ground water withdrawn annually shall
be consumed and the well owner shall demonstrate to the reasonable satisfaction of the State Engineer that no more than 98%of the water
withdrawn will be consumed.
15) This well is subject to administration by the Division Engineer in accordance with applicable decrees,statutes,rules,and regulations.
NOTE:The ability of this well to withdraw its authorized amount of water from this non-renewable aquifer may be less than the 100 years
upon which the amount of water in the aquifer is allocated,due to anticipated water level declines.
NOTE:To ensure a maximum productive life of this well,perforated casing should be set through the entire producing interval of the
approved zone or aquifer indicated above.
NOTICE:This permit has been approved for a location other than applied for in order to place the well oustide 600 feet of any other
production well.The proposed acre-foot amount was also changed in order to be sufficient for the proposed uses. You are hereby notified that
you have the right to appeal the issuance of this permit,by filing a written request with this office within sixty(60)days of the date of issuance,

FINDINGS OF THE STATE ENGINEER
IN THE MATTER OF AN APPLICATION FOR A PERMIT TO CONSTRUCT A WELL IN
WATER DIVISION NO. 1,WELD COUNTY, COLORADO
APPLICANT : PEDRO SAUCEDO & GABRIELA RAMIREZ
AQUIFER: LARAMIE FOX HILLS
PERMIT NO.: 64214-F
In compliance with C.R.S. 37-90-137(1) and the Statewide Nontributary Ground
Water Rules, Pedro Saucedo and Gabriela Ramirez, (hereinafter "applicant") submitted
an application for a permit to construct a well. Based on information provided by the
applicant and records of the Division of Water Resources, the State Engineer finds as
follows:
1. The application was received complete by the State Engineer on March 7, 2006.
2. The applicant proposes to construct the well in the NE1A of the NW% of Section 22,
Township 2 North, Range 66 West, 6th Principal Meridian.
3. The proposed well is located outside the boundaries of a designated ground water
basin.
4. The applicant proposes to apply the water withdrawn from the well to the following
beneficial uses: Commercial for oil field company, 5000 square foot garage, and
domestic use.
5. The proposed maximum pumping rate of the well is 15 gallons per minute, and the
requested average annual amount of ground water to be withdrawn is 4 acre-feet.
6. The applicant is the owner of the land on which the well will be constructed.
7. The proposed well would withdraw ground water from the Laramie Fox Hills aquifer
(hereinafter"aquifer"), which, according to the Denver Basin Rules, is located 570 feet
to 860 feet below land surface at the location of the proposed well.
8. The location of the proposed well is more than 600 feet from any existing well
completed in the aquifer.
9. According to a sworn statement, the applicant owns, or has consent to withdraw
ground water underlying 34.9 acres of land as further described in said statement,
which is attached hereto as Exhibit A.
10. Withdrawal of ground water from the aquifer underlying the land claimed by the
applicant will not, within one hundred years, deplete the flow of a natural stream at an
annual rate greater than one-tenth of one percent of the annual rate of withdrawal and
therefore the ground water is non-tributary ground water as defined in C.R.S.
37-90-103(10.5).
Applicant: Pedro Saucedo and Gabriela Ramirez
Aquifer:Laramie Fox Hills
Permit no. 64214-F
11. In considering whether the requested permit shall be approved the provisions of
C.R.S. 37-90-137(4) and the Denver Basin Rules shall apply. Withdrawals shall be
allowed on the basis of an aquifers life of 100 years, C.R.S. 37-90-137(4)(b)(l).
12. The quantity of water in the aquifer, exclusive of artificial recharge, underlying the 34.9
acres of land described in Exhibit A is 810 acre-feet. This determination was based
on the following as specified in the Denver Basin Rules:
a. The average specific yield of the saturated aquifer materials underlying the land
under consideration is 15 percent.
b. The average thickness of the saturated aquifer materials underlying the land
under consideration is 155 feet.
13. A review of the records in the State Engineer's office has not disclosed that there are
any existing wells or other water rights claiming or diverting ground water from the
aquifer underlying the land claimed by the applicant.
Based on the above, the State Engineer finds that there is water available for
withdrawal by the proposed well and no material injury to vested water rights would result
from the issuance of the requested permit subject to the following conditions:
a The allowed average annual amount of water to be withdrawn from the aquifer by
the well shall not exceed 4 acre-feet as requested by applicant.
b The well shall be constructed no more than 200 feet from the location specified on
the permit application.
c. The applicant shall submit geophysical and lithologic logs after the construction of
the well. The geophysical logs shall be obtained from the hole before the casings are
installed.
d. The maximum pumping rate of the well shall not exceed 15 gallons per minute.
e. A totalizing flow meter must be installed on the well and maintained in good
working order. Permanent records of all diversions must be maintained by the well
owner (recorded at least annually) and submitted to the Division Engineer upon
request.
f. Production is limited to the Laramie Fox Hills aquifer. The well must be
constructed with plain, non-perforated casing properly grouted so as to prevent
intermingling of water between aquifers.
g. The owner shall mark the well in a conspicuous place with appropriate well permit
numbers, name of the aquifer, and court case numbers. He shall take necessary
means and precautions to preserve these markings.
h. Pursuant to C.R.S. 37-90-137(9)(b) and the Denver Basin Rules, no more than
98% of the non-tributary ground water withdrawn annually shall be consumed and
the applicant shall demonstrate to the reasonable satisfaction of the State Engineer
that no more than 98% of the water withdrawn will be consumed.

RE: LS.D.S. Engineered Design Septic System
Pedro Saucedo
Lot A, No. 1309-22-2-RE 4224
Platteville, Colorado
Dear Ms. Smith:
Please find enclosed an engineered design system for an Individual Sewage Disposal
System (ISDS) for the above referenced site. A representative of Two Rivers Testing, Inc.
performed the soil percolation tests on March 15, 2006. A limiting zone of claystone
bedrock was encountered at a depth of five feet. The percolation rate was determined to be
10.0 minutes per inch (See summary). Groundwater was not encountered to a depth of
eight feet An engineer designed septic system is required since the facility is proposed as
a shop(commercial endeavor).
The system has been sized for as a office with a maximum of 2 people per day. The owner
of the site have stated they may build a three bedroom home in the future and would like to
add the home to the septic system. Therefore, the system has been designed for the shop
and single family residence. The ISDS was designed to use a 1000-gallon two-
compartment septic tank and a minimum 325 effective square foot absorption trench using
a minimum of 21 Standard Infiltrator® chambers: If the septic system is only constructed
for the,•shop/office a 100O-gallon two-compartment septic tank and a minimum of 20
effective square foot absorption trench using a minimum of 2 Standard Infiltrator®
chambers would be required. Based upon the enclosed calculations, the system should be
sufficient to handle the proposed flow.
The absorption bed should be constructed with standard Infiltrator® chambers installed in
accordance with the manufacturer's recommendations. The bottom of the Infiltrators could
be placed no more than one foot below existing grade: A minimum of one-foot (1) and a
maximum of two feet (2') of fill material should then be placed'over the units. The on-site
soils can-be used as cover material:
A lift station and pump is not expected to be required. However, if needed, the lift station
should be constructed of concrete and placed down gradient of the septic tank.

The Engineered Designed System was designed in accordance to Weld County Individual
Sewage Disposal System Regulations. The owner will have to meet the required distance
criteria as shown in Table 1 of the Individual Sewage Disposal System Guide for Weld

NOTE:The minimum distances shown above shall be maintained between the system components and the physical
features described. Where soil, geological or other conditions warrant, greater distances may be required by the Board of
Health or by the Water Quality Control Commission pursuant to C.R.S. 25-8-206 in accordance with the authority
prescribed by law and rules and regulations implemental of said section. Components which are not water tight should not
extend into areas of the root system of nearby trees. For repair or upgrading of existing systems where the size of lot
precludes adherence to these distances, repaired facility shall not be closer to water supply components than the existing
facilities. For new systems, variances may be given from these distances, but shall not be closer than the CDH distances.
1. Distance shown shall not apply to treatment plants or effluent lines where recycling is permitted.
2. Crossing or encroachments may be permitted at the points as noted above provided that the water conveyance
pipe is encased for a minimum distance of ten (10)feet on each side of the crossing.A length of pipe shall be
used with a minimum Schedule 40 rating of sufficient diameter to easily slide over and completely encase the
water conveyance. Ridged end caps of at least Schedule 40 rating must be glued or secured in a watertight
fashion to the ends of the encasement pipe. A hole of sufficient size to accommodate the pipe shall be drilled in
the lowermost section of the ridged cap so that the conveyance pipe rests on the bottom of the encasement pipe.
The area in which the pipe passes through the endcaps shall be sealed with an approved underground sealant
compatible with the piping used.
3. Add 8 feet additional distance for each 100 gallons per day of design flow over 1000 gallons per day as specified
in the table, unless it can be demonstrated by a registered Professional Engineer or Certified Professional
Geologist that a mechanical or natural barrier will prevent contamination.
4. Encroachments may be permitted provided the water or wastewater conveyance pipe is encased as in (2) above,
specified in the table.

Note:The minimum distance shown above shall be maintained between the system components and the ground features
described. Where geological or other conditions warrant,greater distances may be required.
a. Components which are not watertight should no extent into anticipated root systems of nearby trees. Distance shown
shall not apply to treatment plant.
b. Distance shown shall not apply where effluent discharge is not required to be contained on the premises of origin.
c. Crossings may be permitted where pipelines are constructed of sufficient strength to contain flows under pressure.
d. Waterway or stream is defined as a feature which drains a watershed greater than one(1)square mile.
e. Swale or gully is a narrow ravine or shallow depression which carries water after a period of precipitation to include
snow runoff and has limited water sources and a drainage basin of one(1)square mile or less.
f. The Department may allow a lesser distance for fully lined systems in instances where the flood zone is not a factor for
consideration.
g. The Department may allow lesser distances which meet State guidelines where irrigation ditch laterals not serving as
public water sources and where such lesser distances would not cause pollution or be detrimental to the septic system.
h. Add eight(8)fret additional distance for each 100 gpd of design flow over 1,600 gpd.
i. The setback for a slit trench shall be fifty(50)feet.
