FROM: Kevin R. Gertig, Utilities Executive Director
DATE: August 6, 2019
RE: Status of City Staff Discussions Regarding Water and Wastewater Service to the
Montava Planned Unit Development
_____________________________________________________________________________
This memo provides a summary of the status of City Staff discussions related to water and
wastewater service for the Montava Planned Unit Development (PUD).
Summary of Staff Discussions to Date:
x City Staff has been actively involved in discussions related to water and wastewater service
for Montava PUD since late 2017.
x Those discussions have included numerous conversations with the East Larimer County
Water District (ELCO) and the Boxelder Sanitation District (BSD), which are the districts that
provide water and wastewater service to the land where the Montava PUD is located.
x Regarding water service, City Staff and ELCO Staff are currently working on developing a
draft three-party agreement between the City, ELCO, and the developer to facilitate part of
the treated indoor water service for the Montava PUD. (It is City Staff’s understanding that
outdoor water use on the Montava PUD would be provided by developer-owned wells or
other raw water sources.) Under the concept being developed, the Montava PUD would
receive water service from ELCO and the developer would meet part of ELCO’s raw water
requirements by paying cash to the City, and the City would deliver raw water to ELCO for
the Montava PUD. This agreement is currently in draft form and, once a draft is finalized,
will require approval by City Council, the ELCO board of directors, and the developer.
x Regarding wastewater service, representatives of the City and BSD have had various
discussions related to the Montava PUD. City Staff will continue to discuss opportunities to
collaborate on wastewater service for Montava PUD with BSD.
Any agreements regarding water and wastewater service to the Montava PUD will not be
completed before this matter is before the Planning and Zoning Board and may not be complete
before City Council considers the Montava PUD Master Plan.

Dear Mr. Frickey and Ms. Statman-Burruss:
Thank you for the chance to comment on the upcoming public hearing scheduled for August 15. I cannot
attend, but want to weigh in on this proposal.
I live in Nedrah Acres, just south of Country Club Road. That road is the ONLY way in/out of my
subdivision, and it is already clotted beyond belief. It is not uncommon to sit for 5 to 8 minutes at the
corners of Country Club and Lakeview, Warren, Longview, and Belmont, WAITING to enter Country Club
Road at morning and evening rush. Additionally, Lemay is also clotted at Country Club, Willox, and
Conifer (and desperately needs a stop light at one of these intersections.) Montava would add additional
burden to these thoroughfares.
Country Club Road is also (illegally) used by numerous trucks. Montava would add thousands more
automobiles to that road daily, not to mention Lemay. Country Club cannot support this level of traffic.
Without completion of Suniga and extension of Turnberry south along the Adriel Hills golf course, the
infrastructure IS NOT IN PLACE to support a development the size of Montava. This proposal cannot
pass.

Subject: Re: Question re: Montava's "voting district"
Hi Clay:
Yikes! Yes, please do pass my concerns on to the P and Z board and City Council. In yesterday's Denver Post, there was a
frightening article about the same kind of voting district in which only 8 voters -- 8 -- all employees of the development
entity -- passed a measure that holds for 11 years (and of course the voting district board members were also ALL
employees of the developer)!! The taxes on the district's new home buyers are now drowning them in debt as they were
unaware of the tax implications when they bought their homes. Now many of them are losing their homes, because they
are unable to afford the taxes.
I think the public should know just how many "voters" will comprise this district/will be voting on this issue and who
really will be paying the tab for this shiny new development.
Sincerely,
Virginia Mohr-Callahan

Hi Clay
I'm sorry. I don't understand. Right now that "district" is UNDEVELOPED." Who actually lives in that "district" to vote? It

Subject: Question re: Montava's "voting district”
Good Morning:
Thanks again for passing on our Montava concerns in advance of next week's hearing. After reading today's article in the
Coloradoan, we understand the Montava developer hopes to have an issue on the November ballot because of
Montava's effect on homeowners' taxes/and TABOR implications.
Which homeowners would comprise this special "voting district"? City residents only, or all stakeholder property owners
who live near the proposed development? As north Fort Collins residents whose property happens to fall in the county, I
am opposed to only city residents voting on this issue. ALL property owners -- regardless of geography (city or
county) whose property/lifestyle would be affected by Montava's approval need to be able to vote on this issue.

Subject: Multiple Developers- Question and Concern
Dear Mr. Summers,
In the Coloradan today we were informed of the proposal to build 3,900-4,000 new homes in north
Fort Collins. We have been following the "Hughes Property" proposal recently…going to all the meetings
and are concerned about the dreadful, cramped, seriously uncreative and "Silicon Valley-like" proposal
ongoing in one of the precious property “JEWELS” of Fort Collins. Little, if any thought has gone into the
impact of 600-700 new homes in that area vs the idea that it deserves way more thought and inclusion
of multi-use opportunities that could please way more people than just those who need housing. It is
such a shallow uncreative plan with little thought of the future consequences on roads, traffic,
environmental concerns, etc...
Now we learn of 3,900-4,000 new homes being developed north of town. Please tell us that it will
take some of the pressure off building such a large amount of residences on the Hughes property and
some new ideas that are more indicative of the multi-use and outdoor recreational philosophy the
residents of Fort Collins would like to see.
These are stressful, difficult times here in America and many of us are losing hope that we have a
voice that is seriously going to be heard by our officials and big money. Please comment and reassure us
that this is not just another CSU Stadium affair and that those who make the decisions are not just going
thru the motions of public meetings so that they can say that they did.

Comments on Montava Planned Unit Development.
I am sorry I wont be able to attend the hearing; however, these are my comments:
Traffic problems already exist at Vine and Timberline since there is only a stop sign and no turn lanes
plus being blocked, by the RR, for up to 30 minutes. Also, the narrow roads there that cause huge
backups when people are turning turn left!!
There is also a rumor that Waterglen Drive will be an North Entrance and South Exit to this proposed
development. Why, since it is just two lanes without turn lanes except at Vine.
Traffic is already a problem at Lemay and Vine. Now, unless the problems above are taken care of before
this development procedes, we also will be effected badly!!

Hi Sylvia,
Unfortunately, my wife and I will be out of the country and miss the public hearing on August 15th
.
We are excited for some commercial development near Mountain Vista. There is physically nothing
available in our area and the population growth demands more options to support the influx. I
would love to have a grocery store and gas station at a minimum. Please let me know if there is
anything we can do to further our support for this initiative.

Subject: Montava
Good Morning,
I will be unable to attend the meeting on the 15th, but would like to give you my
thoughts on this proposal. I signed up for the Montava newsletter and have
watched with growing trepidation the plans they have for this space. I have
posted numerous questions on their web site, none of which have been answered.
I live on Marshfield Lane and back on to Turnberry, in recent months there has
been a huge increase in tractor trailer traffic along Turnberry along with an
increase in noise 24/7. Montava wants to add, I believe, 4,000 plus residences a
transportation hub, a community farm, light industry and shopping. I will ask you
the same question I asked them numerous times, where is all this traffic going to
go?? The roads are at capacity now and this can only result in total gridlock. We
keep being told that this will be a bike friendly community etc. etc. I am sure
from your past experience this does not and again will not happen. Cars and
trucks will be added to inadequate roads and do not tell me the roads will be
improved look at Lemay and Timberline on their north ends a traffic nightmare. I
also do not want Turnberry widened, we already had it re-aligned just after we
moved in in 2011 much to our surprise and disgust I might add.
In closing I would like to say I hope that this time the planning committee takes
in to account the existing residents and does not allow this ridiculous
developement as it is written to go through, or perhaps even at all. The only
beneficiary that I can see is the developer who stands to make millions at the
expense of all of us.
Thank you,

Subject: Montava Public Meeting - Comments in Advance
Hello Sylvia,
Thanks for providing the opportunity to comment in advance on the proposed Montava
development. I do plan on attending the meeting but wanted to provide just one piece of
preliminary feedback, and will have more at the meeting.
The developer (see pg 16, attached) is proposing a Turnberry extension that was rejected some time
ago and is inconsistent with the Ft Collins Master Street Plan. Furthermore, Timberline is INCORRECT
as well after it leaves the proposed Conifer extension.
According to the last Ft Collins Master Street Plan (http://citydocs.fcgov.com/?
cmd=convert&vid=192&docid=1880869&dt=Master+Street+Plan+Map), the City proposed
Turnberry extension does NOT go due south when it hits Mountain Vista, but instead follows
Mountain Vista for a little bit then branches diagonally before it hits Timberline. I recall when this
was discussed and the homeowners in Adrial Hill voiced their concern about having this extension
right next to their properties, and the City - to their great credit - listened to the concern and
modified the Master Plan accordingly, to what we have today.
The developer (pg 16) appears to have disregarded the Street Master Plan or maybe worse, has not
looked at it, or worse, feels like they can do anything they want. And what's worse is they appear to
be labeling this as a done deal!
This is just one example I found in a cursory look, but who knows what else they are proposing that
is at odds with the Street Plan. Is someone going over this with a fine tooth comb, or does Ft Collins
expect concerned citizens to do this work?
I will for sure have more comments at the meeting. I'm also happy to talk to your Streets
Department on this. My phone number is below.
Again, thanks for the opportunity to provide feedback ahead of time! Greatly appreciate you
reaching out.

Reference: Phase II Environmental Site Assessment Summary Report
City of Fort Collins Brownfield Assessment
Montava, 2316 Giddings Road and East County Road 52, Fort Collins, CO (Site)
TRC Project No. 241300.0001.0000
Dear Ms. Everette:
This report summarizes the findings of a Phase II Environmental Site Assessment (Phase II ESA)
conducted by TRC Environmental Corporation (TRC) at the request of the City of Fort Collins at
Montava, at 2316 Giddings Road and East County Road 52, Fort Collins, Colorado (Site) for a United
States Environmental Protection Agency (USEPA) Brownfields Assessment Grant. A Site Location
map is shown on Figure 1.
1. EXECUTIVE SUMMARY
The Phase II ESA included advancing eight monitoring wells, installing nine soil vapor points, and the
collection and laboratory analyses of soil and groundwater samples to evaluate potential subsurface
impacts at the Site. Analytical results documented that the constituents of concern (COC) were either
not detected above laboratory detection limits or were detected at concentrations below applicable
regulatory screening levels, with the exception of arsenic in all eight soil samples and nitrate in seven
groundwater samples. However, the concentrations of arsenic in the eight locations are below USEPA’s
background arsenic concentration in Colorado, so arsenic is not considered a COC at the Site. The
investigation results demonstrate that the risk to human health or the environment does not exceed the
USEPA’s Regional Screening Level (RSL) of 10 E-06.
2. BACKGROUND
The Site is located on an approximate 850-acre parcel owned by the Anheuser-Busch Foundation of
Saint Louis, Missouri. The parcel has two plugged and abandoned oil and gas wellheads in the north
and northeast portion of the parcel. This investigation was solely focused on the area immediately
surrounding the plugged and abandoned oil and gas wells (within a 200-foot radius).
ERO Resources Corporation conducted a Phase I ESA at the Site on behalf of the Chase Merritt. The
results of the Phase I ESA were summarized in a corresponding report dated September 21, 2017
(ERO, 2017). The Phase I ESA identified the presence of a Historical Recognized Environmental
Condition (HREC) at the Site. Specifically, the Phase I ESA indicates that the plugged and abandoned
oil and gas well heads located on the northwest and northeast portion of the parcel represents a HREC.
3. OBJECTIVES OF THE PHASE II ESA
The objective of the Phase II ESA was to:
ITEM 3, Phase II Enviro Site Assessment Report
Supplemental Packet Pg. 12
City of Fort Collins Brownfield
Phase II Environmental Site Assessment
Page 2
• Confirm that the plugged and abandoned wellheads located on the northwest and northeast
portion of the Site have not impacted the groundwater or soil.
4. SCOPE AND METHODOLOGY OF THE PHASE II ESA
4.1 Introduction
The Phase II ESA consisted of:
• Advancement of eight soil borings for soil screening and soil sampling with a track mounted
Geoprobe®;
• Collection and laboratory analysis of eight soil samples collected from each of the eight borings;
• Installation of eight temporary ground water monitoring wells at the boring locations;
• Collection and laboratory analysis of eight ground water samples from each of the eight
monitoring wells;
• Installation and sampling of nine soil vapor monitoring points; and
• Scan of each area with an infrared camera
TRC conducted a site inspection prior to initiating the field work to inspect the Site and locate the
borings.
4.2 Soil Investigation
On February 26, 2019 and March 5, 2019 TRC and its subcontractor Remington Technologies, LLC
installed eight soil borings SB-1 through SB-8 at the locations shown on Figure 2. Prior to installing the
soil borings, utility clearance was conducted and a hand auger was used to remove soil from each
borehole to an approximate depth of four feet to verify that no utilities were present at the boring
locations.
The soil borings were advanced using a Geoprobe® with direct push capabilities. All eight soil borings
were advanced to a depth ranging from 25 - 41 feet below ground surface (ft bgs) to evaluate soil
conditions at each boring location. Soil was collected continuously via five-foot direct push intervals,
utilizing a new sample liner each flight. A TRC scientist visually screened and logged the descriptions
of the soil encountered in each boring. Photo-ionization detector (PID) readings were also recorded for
each two-foot soil interval. Boring logs with soil descriptions, visual observations, and PID readings are
presented in Appendix A. The soil at boring locations consisted of fine to medium sand with some silt.
No free or residual product was detected at any of the borings.
One unsaturated soil sample was collected from each original soil boring location. Soil from each
boring did not exhibit any apparent impacts; therefore, a soil sample was collected directly above the
water table or from the interval of highest PID reading. The samples were transferred directly into
laboratory-supplied sample containers. Each sample container was labeled with a unique identification
number specifying the sample location, the time and date of sample collection, the analytical
parameters required, the Site name, and the sampler’s initials. The samples were preserved, as
appropriate, and chilled to approximately 4ºC under chain-of-custody until shipped to the laboratory.
Each of the soil samples was analyzed for:
• DRO by Semi-Volatile Organic Compounds (SVOC) by Gas Chromatograph (GC) Method 8015
• Gasoline Range Organics (GRO) by Volatile Organic Carbon (VOC) by GC Method 8015D/GRO
• Benzene, Toluene, Ethylbenzene, Xylenes (BTEX) by GC/Mass Spectrometer (GC/MS) Method

Method 6010B
4.3 Ground Water Investigation
The soil borings had one-inch diameter temporary wells installed to approximately 25 to 30 ft bg and
were constructed with 10 feet of 0.10-slot PVC screen at the bottom and blank PVC casing at the top.
The monitoring wells, TW-1 through TW-8, were constructed as temporary monitoring wells with
appropriately sized screen and sand filter packs. Figure 2 shows their approximate locations. TRC
developed the monitoring wells and allowed 24 hours for the wells to equilibrate after development
before sampling.
Prior to initiating ground water sampling activities, ground water level measurements were first
collected from each well at the Site. The depth from the top of casing (TOC) to the top of the ground
water was recorded at each well for use in estimating ground water elevations. Ground water level
measurements were recorded on the Field Forms presented in Appendix B.
Hand bailing and sampling procedures were utilized in connection with the ground water sampling
activities. Disposable hand bailers were used at all eight monitoring wells since the ground water levels
were too deep for the peristaltic pump to lift water to the surface. Prior to sampling, each well was
purged. Field parameters including pH, oxidation reduction potential (ORP/Eh), dissolved oxygen (DO),
specific conductance, turbidity, and temperature of the ground water being purged was measured
periodically and recorded in the field notebook. The visual appearance of the ground water was also
recorded. Three field measurement readings were recorded prior to sampling.
Care was taken to minimize agitation and aeration of the samples during sample collection activities.
Each ground water sample was transferred directly into appropriate pre-preserved laboratory-supplied
sample containers. Each sample container was labeled with a unique identification number specifying
the sample location, the time and date of sample collection, the analytical parameters required, the Site
name, and the sampler’s initials. The samples were preserved, as appropriate, and chilled to
approximately 4°C under chain-of-custody until shipped to the laboratory. Ground water sample
collection data was recorded on the Sampling Form presented in Appendix B.
Seven (TW-1 – TW-7) of the ground water samples were analyzed for:
• DRO by SVOC (GC) by Method 8015
• GRO and BTEX by VOC (GC) Method 8015D/GRO
• Methane, Ethane, Ethene by VOC (GC) Method RSK175
• Bromide, Chloride, Nitrate and Nitrite, Sulfate by Wet Chemistry Method 9056A
• Alkalinity by Wet Chemistry Method 2320 B-2011
Monitoring well TW-8 did not produce sufficient sample volume for a complete analytical set. TW-8
ground water samples were analyzed for:
• DRO by SVOC (GC) by Method 8015
• GRO and BTEX by VOC (GC) Method 8015D/GRO
• Methane, Ethane, Ethene by VOC (GC) Method RSK175

4.4 Soil Vapor Investigation
Nine soil vapor points were constructed on Site. Four points were installed surrounding each of the
plugged and abandoned well while the last point was installed at the edge of the property as a
background control sample. The nine soil vapor points constructed around the plugged and abandoned
well, SVP-1 through SVP-9, were installed in five-foot intervals to a maximum radius of 20 feet. The
soil vapor points were installed to a target depth of approximately three to five feet bgs by a direct push
drill rig. The soil probes were constructed with a dedicated stainless-steel soil vapor tip, connected to
the ground surface with Teflon tubing. After the soil vapor probes were installed to the target depth, the
boreholes were backfilled with hydrated bentonite to create a seal and completed at-grade with flush
mount surface completions. Field screening of soil vapor points using an Eagle multi-gas meter did not
detect significant VOC concentrations above background levels in any of the samples. The soil vapor
field sampling forms are presented in Appendix B.
4.5 Infrared (IR) Camera Scan
An IR camera was used to scan the area around the plugged and abandoned well locations. The
plugged and abandoned wells were scanned with the IR camera from each of the eight monitoring well
locations. The camera used optical gas imaging to determine the presence or absence of a methane
leak in real time. The IR camera did not determine the presence of a leak at the plugged and
abandoned wells.
4.6 Decontamination Procedures
Down-hole drilling equipment was decontaminated with high pressure tap water prior to each soil
boring. Sampling tools were decontaminated using a trisodium phosphate cleaning detergent and tap
water rinse followed by a distilled water rinse. The equipment and tools were decontaminated prior to
each soil boring and collection of each sample. Hand bailers from ground water purging and sampling
activities were discarded after the collection of project samples.
5. RESULTS
The sampling results for soil were screened against the USEPA Residential Soil RSLs, Colorado
Department of Public Health and Environment’s (CDPHE) Groundwater Protection Values Soil Cleanup
levels, and COGCC 900 Series Rule Table 910-1 screening levels. The sampling results for
groundwater were screened against USEPA Maximum Contaminant Limits (MCLs) and CDPHE
Groundwater Organic Standards.
5.1 Soil Analytical Results
The soil analytical results are summarized in Table 1 along with applicable soil standards. The
laboratory analytical report is provided in Appendix C.
The analytical results indicate that soil within the target area does not contain any COC at
concentrations above the COGCC SLs, the CDPHE Groundwater Protection Values Soil Cleanup
Levels, or USEPA Residential Soil RSL standards, except for arsenic. Arsenic exceeded the USEPA
RSL of 0.68 milligrams per kilogram (mg/kg) and the COGCC SL of 0.39 mg/kg at all eight soil borings
with the highest concentration at SB-5 (6.35 mg/kg). There is no arsenic screening level for the
CDPHE Cleanup Levels. According to the CDPHE, the average background concentration of arsenic in
Colorado is 11 mg/kg. The arsenic concentration at each soil boring is less than 11 mg/kg and there is
no reason to believe arsenic contamination could have occurred on Site. Therefore, arsenic is not a
COC for on-Site soil at the target area. Information regarding the average arsenic background
concentration in Colorado is provided in Appendix D. Additionally, BTEX and TPH GRO and DRO

concentrations were well below the USEPA RSLs, COGCC SLs, and CDPHE Cleanup Levels in all four
borings. These results confirm that there are no COCs in soil at the Site and do not pose any risk to
human health and the environment. Based on the low concentrations of the analytes, the likelihood of
contaminants leaching from the soil into the groundwater and affecting downgradient nearby
groundwater use wells is low.
5.2 Ground Water Analytical Results
The ground water analytical results are summarized in Table 2 along with the applicable USEPA MCLs
and CDPHE’s Groundwater Organic Standards. The laboratory analytical report is provided in
Appendix C.
The ground water samples collected at the Site did not indicate an exceedance over USEPA MCLs or
CDPHE groundwater standards at any of the eight locations, except for nitrate. Nitrate exceeded the
CDPHE groundwater human health standards of 1 mg/L at seven locations with the highest
concentration at TW-03 (17 mg/L). Nitrate is not considered a COC for groundwater due to agricultural
use at the site. There were no detections of BTEX in any of the eight wells and any detections of TPH
were minor. These results confirm that there are no COCs in ground water at the Site and do not pose
any risk to human health and the environment.
5.3 Ground Water Flow Directions
Ground water was encountered at depths that ranged between approximately 18 and 33 feet bgs
(Appendix A). Ground water level measurements (Appendix B) and estimated grade elevations at the
site were used to estimate ground water elevations and develop a ground water elevation contour map
(Figure 3). No survey was completed therefore ground water flows were estimated. Figure 3 indicates
that the horizontal ground water flow direction in the shallow zone is generally southwesterly (i.e., from
the northeast to the southwest), consistent with the Site topography.
6. CONCLUSIONS
The following conclusions are made based on the Phase II ESA results:
• Soil at the Site meets the USEPA RSLs, COGCC SLs, and the CDPHE Cleanup Levels for
RCRA 8 Metals with the exception of arsenic, which was detected at a concentration below the
state background concentration, thus, this constituent is not considered a COC for soil at the
Site.
• Arsenic concentrations detected during this Phase II ESA are all well below the average
background concentration of 11 mg/kg in Colorado and there is no reason to believe arsenic
contamination could have occurred on Site; therefore, arsenic is not considered a COC for soil
at the Site.
• The shallow ground water at the Site meets USEPA MCL standards and CDPHE ground water
standards for BTEX within the target area; thus, these constituents are not considered COCs for
shallow ground water at the Site. Nitrate exceeded CDPHE Groundwater Human Health
Standards but is not considered a COC for groundwater at the site due to agricultural uses.
7. LIMITING CONDITIONS/ASSUMPTIONS
It should be noted that this investigation is limited in nature and extent and was conducted for due
diligence purposes based upon the Phase I ESA conducted by TRC. The scope of work of this Phase
II ESA was based on results from the previous Phase I Investigation, which listed the plugged and
abandoned wellheads as a HREC. As such, the target area evaluated in this Phase II ESA was limited
to constituents likely related to historical operations at the potential REC including TPH-DRO, TPH-

GRO, BTEX, and RCRA 8 Metals in soil, and BTEX, TPH, and dissolved gases in ground water. This
investigation is therefore intended to identify significant impacts to environmental conditions of the Site
to common and suspected COCs based on the Phase I ESA and should not be construed to guarantee
or warrant the Site from environmental impacts or rule out the possibility of impacts to the Site in
locations not evaluated as part of this assessment.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.

Arsenic Concentrations in Soil
Risk management guidance for evaluating reviewed/revised July 2014
Regulatory Limitation
This guidance does not modify, replace, or pre-empt any existing statutory or regulatory requirements, enforcement actions,
agreements, policies or other legal mechanisms that may govern actions within the Hazardous Materials and Waste
Management Division’s (the “division’s”) various remedial programs. In the event of a conflict between this guidance and
existing risk assessment guidance and other programmatic requirements, this guidance defers to the various legal and
operating mechanisms of those remedial programs.
This guidance was developed with the division’s remedial programs in mind. Other state and federal agencies are not
obligated to use the process outlined herein, although the same analysis could apply to other sites undergoing investigation
and cleanup where testing for arsenic is required and it may be present in sampled environmental media. Parties wanting to
use this guidance at their site must seek approval to do so from the regulatory agency responsible for overseeing their
remedial activities.
Purpose
The division has prepared this guidance for the purpose of making preliminary determinations when screening data collected
from sites that don’t necessarily have a reason to believe arsenic contamination may be present, such as a routine Phase II
investigation conducted prior to a property transaction. This guidance is simply meant to inform the regulated community of
their responsibilities in managing arsenic risks: it is not regulation, nor does it constitute an enforceable standard that must
be complied with.
Background
Arsenic is naturally occurring in some geologic environments in Colorado due to weathering and erosion of bedrock and soil,
including highly mineralized areas that are mined for metal ores. It is present in more than 200 different minerals, the most
common of which is called arsenopyrite. It may also be present in the environment due to a number of anthropogenic
activities including: military operations and firing ranges; mining, especially sulfide ores; smelting copper, gold and lead ores;
preservation of wood (CCA); chicken feed operations and associated manures (CAFO) due to arsenic-containing growth
promoters; tanning and taxidermy operations; coal-burning emissions and ash-derived residues from power plants; and may
be present in landfills and landfill-derived leachate. Arsenic may also be found due to the manufacture, use and disposal of:
ammunition; fireworks; pigments (paint, paper, ceramics, etc.); older herbicides, insecticides, and pesticides (examples:
monosodium methanearsonate (MSMA), disodium methanearsonate (DSMA) and lead-arsonate); electronics containing
Gallium-Arsenide-Selenium (GAS) semi-conductors; lead acid battery plates; glass; and some pharmaceuticals. Other
anthropogenic arsenic sources may likely exist. Arsenic contamination in soil is of public health concern due to its toxic
effects as a carcinogen and a non-carcinogen. Making risk management decisions about arsenic can be difficult because
natural occurring concentrations in soil often exceed carcinogenic risk based exposure values.
This guidance was prepared by the division using a data set of background arsenic concentrations developed by the U.S. EPA
Region 8. The data set includes over 2,700 samples from 44 counties in Colorado. The areas sampled included: native
grasslands; agricultural areas; urban mixed land use; and mining. A summary of the data set is presented in the table below.
The complete data set may be found on the U.S. EPA Region 8’s website at http://www2.epa.gov/region8/hh-exposure-
assessment.

Urban Mixed Use 6-19

ITEM 3, Phase II Enviro Site Assessment Report
Supplemental Packet Pg. 132
Division Guidance Regarding Background Arsenic Concentration
The division’s approach to evaluating arsenic in soil is depicted in the following flowchart. This guidance assumes that, based
upon the size, history and environmental concerns associated with a particular site, an adequate amount of arsenic data has
been obtained to make a determination regarding arsenic concentrations in soil. It isn’t meant to be a guide on how to
conduct a background study for risk assessment and/or site closure purposes. Guidance on the subject of data collection and
analysis needs for conducting a background study should be sought from other published sources. Soil samples should be
collected and analyzed for arsenic if the site history suggests it may be present as a result of anthropogenic activities.
However, since arsenic is one of the chemicals included as part of a standard “metals” analysis package from a laboratory,
you may already have obtained arsenic data for your site.
The current residential/unrestricted land use remedial objective for inorganic arsenic is 0.67 mg/kg (U.S. EPA regional
screening level). If arsenic concentrations at your site are lower than 0.67 mg/kg, the division will require no further action to
address arsenic in soil. If arsenic concentrations are lower than 11 mg/kg (the average of the 95% UCLM of background
concentrations found by the U.S. EPA in Colorado), and releases of arsenic could not have occurred at the site, based on
historical data or process knowledge, the division will require no further action to address arsenic in soil. If arsenic
concentrations are greater than 0.67 mg/kg, and the available information suggests that a release of arsenic could have
occurred at the site, the division will require additional evaluation of the data and possibly additional sampling to determine
whether corrective measures for arsenic are required. This evaluation may include a site specific background study with
sampling from offsite locations, and/or additional sampling in areas of the site where activities that could have contributed to
environmental contamination never occurred. Please consult with the division prior to performing any background study. If
it can be demonstrated that arsenic concentrations in soil are unrelated to site activities, the division will require no further
action regarding arsenic. It should be noted that material such as arsenic-bearing mine tailings or oil and gas drill cuttings,
although derived from a naturally occurring source material, are not considered to be naturally occurring background once
they have been generated through human activity. Therefore, mine tailings and drill cuttings may be subject to remediation
if ecological or health-based concentrations are exceeded.

Arsenic is not a chemical of concern.
Is there any reason to suspect that arsenic or
arsenic containing materials may have been
used onsite?
Do sampling results
exceed 11 mg/kg?
Arsenic may be a chemical of concern.
Contact the division and coordinate with
the appropriate remedial program to
further evaluate the site.
Do sampling results
exceed 0.67 mg/kg?
Arsenic is not a chemical of concern because
concentrations are below Residential/Unrestricted
