Re: Perry Pit, AmUSR-921, Request for Board Hearing
Enclosed you will find two documents that demonstrate Asphalt Paving Company's
impending satisfaction of the two Conditions set forth in its Use by Special Review case as
prerequisite to a hearing before the Board of County Commissioners.
As you will recall from the clarification we received during the Planning Commission
hearing, Condition 2A requires Asphalt Paving Company to submit trip tickets to the
Department of Public Works so that they may verify that turn lanes are not warranted at the
project entrance. Trip tickets were forwarded to Diane Houghtaling on September 21'
and a copy of that transmittal is enclosed for your reference.
Condition 2B requires a letter from the mineral rights owner to be on file, stating that the
proposal adequately incorporates oil and gas facilities into all plans. A mineral rights letter
dated September 21, 2001 was sent to the County under its own cover; a copy of that
letter is enclosed for your records.
Please schedule the AmUSR-921 case for a hearing before the County Board when you
have had a chance to speak with Diane Houghtaling in Public Works. If you have any
questions relating to this request or this permit, please call me at 303/274.4277.

Re: Perry Pit Amendment, AmUSR-921
Enclosures
1. Summary Sheet of Randomly Selected Trip Tickets, Perry Pit site
2. Trip tickets for Perry Pit site (15 days)
At the Planning Commission hearing for the Perry Pit Amendment on September 4'h, we
clarified the Public Works Department's needs under USR Condition 2A. This condition states
that the Public Works Department requires additional information regarding traffic generated
by the sand and gravel operation. Specifically, the County requires data that show turn lane
improvements at the entrance to the site are not necessary due to the actual traffic levels
being far below the level at which turn lanes and other improvements are warranted.
Enclosed are trip tickets from the Perry Pit site for a randomly selected set of 15 days (5 days
in each of the summer months). As discussed during the Planning Commission hearing, these
tickets should be sufficient to provide the documentation needed for traffic engineering
purposes. You will find that these tickets are consistent with the determination that actual trips
generated by the Perry Pit site are far below the level which warranted improvements in the
previous Traffic Study for Weld County Road 6.
Please contact me (303/274.4277) if you have any questions about the enclosed information.
In accordance with Condition 2A of the current Weld County USR resolution, you may also
assist us by forwarding your concurrence to Robert Anderson in the Planning Department after
you have had a chance to review the data.

Attn: Robert Anderson
RE: SPECIAL REVIEW CASE USR-921
Dear Mr. Anderson:
I am writing to you as owner of the property immediately south of Weld County Road 6 and immediately
east of the incorporated Town of Wattenberg, currently under review by your Department as an
Amendment to Weld County Use by Special Review Case USR-921. The surface estate at this property
is currently the site of a sand and gravel mine for Asphalt Paving Co. and the mineral and oil and gas
estate are in the ownership of Asphalt Paving Co.
The County is requiring a statement from the mineral owner at this property that oil and gas drilling have
been adequately incorporated into the design of the site. In this case, the Amended Use by Special
Review will not displace any oil and gas facilities, nor will the plan interfere with future access to the site
for the purposes of oil and gas development. Currently, we have leases with M.E. III Corp. and Patina,
for oil and gas extraction on the property and we intend to maintain the viability of these leases as part of
our interest in the mineral rights at the subject property. You will note that the plans submitted to Weld
County in the current case specifically provide for continued access to, and working space around, the
M.E. III well at the western edge of the site.
Please place this correspondence in the appropriate file for Case AmUSR-921. If you have questions, the
permitting representative, Banks and Gesso, LLC, should be able to provide additional clarification
regarding future plans for the site.
Sincerely,
ASPHALT PAVING O.

Date: 24 October 2001
Re: Adams County Conditions of Approval, Amendment to Perry Pit,
Permit No.921 (AmUSR-921)
On behalf of Asphalt Paving, Applicant in Weld County USR Amendment to Permit No.
921, I have reviewed the Department of Planning and Development Staff Conditions of
Approval. In response to those Conditions of Approval, I would like to submit the
following comments in the order that the conditions were addressed on the resolution
recommended by the Planning Commission.
Condition 1: Development Standards
The list of Development Standards for this Special Review Permit have been added to
Final Plat and the completed plat will be submitted to the Department of Planning
Services upon approval of the Board of County Commissioners.
Former Condition 2A: Supplementary Traffic Information
The Public Works Department required additional information on traffic generated by
Asphalt Paving's operation. The purpose of this data is to demonstrate that turn lane
improvements at the entrance to the site are not necessary. Trip ticket information was
sent to Diane Houghtaling on September 27, 2001. This information successfully shows
that the trips generated by this site are well below the level that which necessitated
improvements in the previous Traffic Study for Weld County Road 6. This condition has
been satisfied by virtue of the scheduling of the Board of County Commissioners
Hearing.
Former Condition 28: Mineral Rights Letter
A letter dated September 21, 2001 from Jeff Keller of Asphalt Paving (mineral property
owner)was sent to the Weld County Department of Planning Services. The letter states
that all oil and gas activities have been sufficiently incorporated into the design of the
2 EXHIBIT
site and that adequate measures have been taken to mitigate the concerns of the
mineral rights owners. This condition has been satisfied by virtue of the scheduling of
the Board of County Commissioners Hearing.
Condition 2A: Department of Wildlife Concerns
Banks and Gesso, LLC responded to the Colorado Division of Wildlife's referral
response of July 11, 2001. A response letter to DOW addressing the Division's
requirements and concerns, was forwarded on August 24, 2001. A copy of this letter
was also sent to Weld County Planning Services.
The DOW was concerned that the change in end use from two ponds to one large one
would cause a reduction in shoreline habitat. The DOW was assured that the minor
reduction in shoreline would be reciprocated with an increase in aquatic habitat. Also,
Asphalt Paving is in the process of amending its 404 Permit (with the Army Corps of
Engineers) and expects the new mitigation program to provide for an enhanced wildlife
habitat.
Condition 2B: Discharge Points Delineation
All discharge points and appropriate routing to the South Platte River will be shown on
the final plat and permitted by the State of Colorado. Modified discharge points are
shown on the revised Weld County USR Extraction Plan and Reclamation Plan and
copies of these revised plans will be included in the final submittal.
Condition 2C: 80' Right of Way for Weld County Road 6
Since Weld County Road 6 is classified as a collector status road, 80 feet of right-of-way
is required at full build-out. To accomplish this, the northern permit boundary has been
moved 10' to the south to allow for 40' of Right of Way from the centerline of Weld
County Road 6. The new boundary line is shown on the revised Extraction and
Reclamation Plans that are to be included in the final submittal.
Condition 2D: Landscape and Buffer Plan
The Landscape and Buffer Plan is in progress to show how impact to adjacent property
owners and public rights of way will be mitigated. A draft of this plan will be submitted to
Planning Services as soon as possible.
Condition 2E: Dust Abatement Plan
The Fugitive Dust Plan was approved and issued under State Permit Number
93WE1382F. The existing Fugitive Dust Plan was updated on 11/2/98 and will be valid
until 11/2/03. This permit will not need amendment, as there will be no change in
equipment used and the annual production rates will not change. A copy of the Dust
Abatement Plan is included with this letter.
Condition 2F: APEN and Emissions Permit
The existing APEN was updated on 11/2/98 and will be valid until 11/2/03. No significant
change in emissions or production will result from the activities generated by this
amendment. The additional 10 acres of mine that will be mined under this amendment
will not affect annual production rates. Therefore, the APEN will not need renewal until
its expiration date in 2003.
Condition 2G: CDPS Permit
The original CDPS Permit was effective on 6/9/93 and renewed on 9/30/97. The current
permit will be valid until 9/30/02. This information was obtained from Nathan Moore at
the Water Quality Control Division at the Colorado Department of Public Health and
Environment. There is no need to amend the permit because mining of the additional 10
acres will not begin until a slurry wall has been installed.
Condition 2H: Waste Handling Plan
The Waste Handling Plan has been sent to the Weld County Department of Public
Health and Environment. A copy is being forwarded to the Department of Planning
Services with this letter. There are two scenarios depicted in these plans, one for mining
only, and one for mining with asphalt production.
Condition 21: Potable Water Supply
Intent to use bottled or containerized water on site is stated in letter sent to the Weld
County Health Department. A copy of this letter is included with this submission.
Condition 2J: Groundwater Monitoring Plan
Asphalt Paving Company intends to continue its current monitoring program. Monitoring
results of the current program are included. The only change to the hydrology of the
area will happen when the slurry wall is installed. Once this is constructed, water
depletion will not be an issue. Monitoring program information will continue to be sent to
the Weld County Department of Health & Environment and the latest update has been
forwarded to them.
Condition 2K: Protected or Endangered Species
In the Planning Commission Hearing of September 4, 2001, the Applicant was asked to
submit documentation that the Perry Site is not suitable habitat for Protected or
Endangered Species. The U.S. Geological Survey is currently conducting a study
entitled "Understanding and Mapping the Relationship between Habitat for the Preble's
Meadow Jumping Mouse and Aggregate Resources". According to this study, the
Preble's Mouse is predominantly located along waterways that have well-developed
riparian vegetation. Vegetation along Lupton Bottoms Ditch is not well-developed and
widely scattered. Also, the soil types on this site are too gravelly and sandy to support
the proper type of hydrophytic vegetation necessary for Preble's Meadow Jumping
Mouse habitat.
A trapping survey for Preble's Jumping Mouse was conducted on a property directly one
mile north of the Perry site. This property is nearly identical to the Perry Site in
topography and environment. Lupton Bottoms Ditch bisects both of these sites. The
trapping survey included more than 750 trap nights in June of 1999. No Preble's
Jumping Mice were found during the duration of the survey.
A survey for Ute Ladies' Tresses was conducted in August of 1995 and the site was
found to be an unsuitable habitat for this orchid. A copy of this study is included.
Condition 2L & 2M: Temporary Substitute Supply Plan
A new Substitute Supply Plan was approved on September 27, 2001 and a copy is
included with this submission. The current Substitute Supply Plan is valid through
December 31, 2001. Applegate Group, Inc. is currently processing a renewal of this
plan and it will be executed before the expiration date.
A referral response from the Assistant State Engineer was received by Weld County
Planning on August 16, 2001. This letter stated that the Substitute Supply Plan would
need to be amended to cover the additional depletions to the stream system caused by
the expansion. However, there will not be any additional depletions from the stream
system after the slurry wall installation. A Temporary Substitute Supply Plan will not
need amendment in the future because the created lake will no longer be tied to the
stream system. Instead, it will be it's own self-sufficient water basin.
Condition 2N: Greater Brighton Fire District
A site plan map has been sent to Kris Krengle of the Greater Brighton Fire Protection
District for his review and to satisfy the District's requirements. When the Fire District
approves the plan, evidence of such will be forwarded to you.
In conclusion, the Applicant is confident that all of the Planning Commission's Conditions
of Approval have been met, with one exception. The updated Landscape and Buffer
Plan has not been submitted. This Plan will be promptly forwarded to Weld County
Planning as soon as it is completed.
Please do not hesitate to call Alex Schatz or myself at 303/274.4277 if you have any
questions or need further clarification on any of these issues.

RE: Perry Pit Substitute Water Supply Plan, M-90-098
Sections 25, 1-1N, R67W, 6"' P.M.
Water Division 1,Water District 2
Dear Mr. Nguyen:
We have received your letter of June 13, 2001, requesting renewal of the above
referenced substitute water supply plan to cover depletions caused by an existing gravel mining
operation. The required fee of$217 for the renewal of this substitute supply plan was
submitted with a March 31, 2000 renewal request Additional Information pertinent to this
request was submitted in a letter dated October 26, 2000.
The substitute supply plan accounts for a variable amount of exposed lake surface that
increases from 6.6 acres in April 1998 to 12.0 acres in June 2001. The entire lake surface was
exposed after December 31, 1980. Consumptive use of water at the property consists of
evaporation from the pond surface area and water lost in product as shown in the attached
table entitled Glover Analysis Input. The delayed impacts to the river are determined using a
Stream Depletion Factor of 30 days. We agree with the calculations in this table.
The ultimate plan for the source of replacement water is recharge ponds that will be
operated through an agreement with the Brighton Ditch Company. The recharge ponds, or
sumps,were used to recharge water during 1998 and 1999 using water diverted when there
was no call on the river. The accretions to the river that resulted from the recharge were
calculated using a Stream Depletion Factor of 280 days. Those accretions are shown in the
attached table entitled Stream Depletion Analysis Using Stream Depletion Factors. We agree
with the calculations in this table. Currently no water is being recharged pending a final
agreement with the Brighton Ditch Company. Until the agreement is finalized, an additional
source of replacement water will be leased Warrior Ditch water from the Bear Creek
Development Corporation during the summer. During the winter, additional replacements will
be made by reusable effluent leased from the City of Greeley.
To replace the depletions that are not replaced by accretions from past recharge the
water leased from the City of Greeley is In the amount of 6.7 acre-feet. This is to replace
depletions during the months of January 2001 through April 2001 and November 2001 through
'December 2001. The water leased from the Warrior Ditch Is In the amount of 22 acre-feet.
This Is to replace depletions during the months of May 2001 through October 2001.
OCT-01-2661 15:52 DIV WATER RESOURCES 303 866 3589 P.03,09
On March 16, 1993 well permit no.42165-F was Issued to expose water in the Perry Pit
The permit was Issued pursuant to a substitute water supply plan approved In 1992. The permit
allows a maximum appropriation of 14.74 acre-feet and limits the water surface area to 3.5
acres. This permit is no longer valid for the current uses.
I hereby approve this substitute water supply plan, in accordance with Section 37-80-
120, C.R.S., (1991), subject to the following conditions:
1. A new well permit must be obtained for the current use and exposed pond surface area
of the gravel pit. The provisions of Colorado Revised Statute 37-90-137(2)prohibits the
issuance of a permit for a well to be located within 600 feet of any existing well, unless
the State Engineer finds that circumstances so warrant after a hearing held in
accordance with the procedural rules in 2CCR402-5. This hearing may be waived if you
are able to obtain statements from the owners of all wells within 600 feet, verifying that
they have no objection to your use of the proposed well. Should a new well permit be
denied for reasons of 600 foot spacing, or any other legitimate reason, approval of this
substitute supply plan will be canceled.
2. The total area of pond surface exposed and the total amount of water to be appropriated
shall not exceed that amount listed on the attached table for each month. Should the
actual values exceed the amounts in the tables, an amendment will need to be filed with
this office.
3. The water commissioner responsible for the administration of this plan is Mr. Bob Stahl,
9378 WCR 25, Ft Lupton. CO 80621, phone no. (303) 857-0742. Adequate records of
diversions, replacements, and amounts of water used for particular uses must be
provided to the Division Engineer and the Water Commissioner on a monthly basis or
other interval acceptable to both of them on a form approved by them.
4. All releases of replacement water must be sufficient to cover all out of priority depletions
and be made under the direction and/or approval of the Water Commissioner. The
replacement may be aggregated to maximize beneficial use. The Water Commissioner
and/or Division Engineer shall determine the rate and timing of an aggregated release.
5. The replacement water,which is the subject of this plan cannot be sold or leased to any
other entity. As a condition of subsequent renewals of this substitute water supply plan,
the replacement water must be appurtenant to this site until a plan for augmentation is
obtained. A copy of this approval letter should be recorded with the county clerk and
recorder. All replacement water must be concurrent with depletions In quantity, timing,
and locations.
6. Approval of this plan is for the purposes as stated herein. This office must first approve
any additional uses for which the water may be used.
7. If reclamation of the mine site will produce a permanent water surface exposing
groundwater to evaporation, an application for a plan for augmentation must be filed
with the Division 1 Water Court at least three (3)years prior to the completion of mining
to Include, but not be limited to, long-term evaporation losses. If a lined pond results
after reclamation, replacement of lagged depletions shall continue until there is no
longer an effect on stream flow.
OCT-01-2001 15:53 DIV WATER RESOURCES 303 866 3589 P.04/09
8. The name, address, and phone number of a contact person who will be responsible for
the operation and accounting of this plan must be provided to the Water Commissioner
and the DMsion Engineer.
9. This plan may be revoked or modified at any time should it be determined that injury to
other vested water rights has or will occur as a result of the operation of this plan.
10. Should a request for renewal of this plan be needed, such renewal request must be
submitted to this office 45 days prior to the expiration date of this plan_
11. Should this substitute water supply plan expire without renewal or be revoked prior to
adjudication of a permanent plan for augmentation, all use of ground eater must cease
immediately.
12. In accordance with amendments to 25-8-202(7), (C.R.S.), and "Senate Bill 89-181 Rules
and Regulations'adopted on February 4, 1992, the State Engineer shall determine
whether the substitute supply is of a quality to meet requirements of use to senior
appropriators. As such, water quality data or analysis may be requested at any time to
determine if the water quality is appropriate for downstream water users.
13. This plan shall be valid through December 31, 2001, unless otherwise revoked or
modified.
14. Acceptance of these conditions will be assumed unless a response to the contrary is
received by this office, the DMsion Engineer, and the Water Commissioner within 2
weeks after receipt of this letter.
Should you have any questions, please contact Kevin Rein of this office or Mr. Dave
Nettles of our DMsion office in Greeley at(970)352-0742.

Weld County Public Works
1111 H Street, P.O. Box 758
Greeley, CO 80632
Dear Mr. Seheitinga,
As a follow-up to our phone conversation yesterday, this is a written memorial of our
progress on traffic related issues at a couple of Use by Special Review sites.
Briefly, with regard to the Green/Croissant project (USR-1329) on the county line, we are
planning to meet at Weld County Public Works on November 14th to discuss
implementation of intersection improvements. You suggested a meeting time of 2:00
p.m. on the 14`h, but Roxann Hayes of Larimer County Public Works requested that we
change the time to 3:00 p.m. to better coordinate with her schedule. Please let me know
if this presents a conflict.
Our most recent discussions have covered the Perry Sand and Gravel Mine (AmUSR-
921) in somewhat more detail, with the Board of County Commissioners hearing
scheduled for this week.
I believe our conversation yesterday reflects the understanding that was arrived at
during the Planning Commission hearing on September 4th. The trip tickets you
reviewed were submitted to the Public Works Department to insure that the Traffic Study
contains current information; because intersection improvements have already occurred
at U.S.H. 85 and WCR 6, the only item for which additional improvements are in
question, as we discussed yesterday, is a left turn bay at the entrance to the Perry mine
site.
This improvement would not be warranted given the current level of traffic, far below the
threshold of 10 vehicles per hour (refer to the Banks and Gesso, LLC transmittal dated
September 21). At the Planning Commission hearing on September 4`h, Don Carroll and
Diane Hougtaling concurred that all traffic and traffic improvement related conditions in
the Use by Special Review process would be satisfied if the Applicant substantiated that
the current level of traffic is below the turning warrant.
I believe our recent correspondence and conversations reflect the resolution envisioned
by the Planning Commission and County staff. As you noted, the relevant provision of
the current draft USR resolution is item 3A, which stipulates that "prior to commencing
operations, the upgrade and paving, and any additional intersection improvements
associated with heavy hauling that may be identified in the requested information. shall
[ ,I, EXHIBIT
I
Traffic Follow-up. USR-1329/ArnUSR-921
October 30,2001
Page 2
be completed and approved by the Department of Public Works." Since, as Public
Works is aware, all other required traffic improvements have occurred under the existing
USR, 3A is triggered only if westbound traffic entering the mine site rises to the warrant
level of 10 vph (or the even more unlikely event that eastbound traffic on WCR 6 turning
right into the site attains a level greater than 25 vph). The present USR Amendment
does not modify the production rate resulting in the current trip tickets, making it unlikely
that traffic into and out of the site will ever reach the warranted level.
To put this issue of item 3A to rest, I am sending a copy of this letter to the Department
of Planning Services, to be placed in the AmUSR-921 file. The Applicant concurs with
your understanding that no left turn bay will be required unless traffic turning into the site
reaches the warranted level (as identified in the original Traffic Study). In the event that
traffic problems do occur on Weld County Road 6 as a result of a high volume of haul
traffic turning into the site, the Applicant will defer to the recommendations of the original
Traffic Study regarding installation of a left turn bay.
If you have any additional comments or suggestions, please contact me at
303/274.4277, or bring them to my attention when I am next in Greeley. Please also
remember to let me know if you are unable to change the Green/Croissant meeting time
on November 14`h.
Sincerely yours,
BA S AND GESSO, LLC
