Project Location and Description
This study is a Level Two – Auxiliary Turn Lane Assessment for a proposed gravel
mining operation in Garfield County, Colorado. This traffic analysis will document:
· Existing site traffic conditions and conditions on the adjacent roadways
· Proposed future traffic demand for gravel pit operations
· Impact to the county roads from the site to the I-70 Exit 94 interchange
· Auxiliary Turn lane analysis for the proposed access driveway
Scott Contracting Incorporated’s (SCI) proposed Rifle Gravel Pit #1 site is located on the
north side of the I-70 North Frontage Road (CR 346) approximately 1.1 miles east of the
CR 346 and Mamm Creek Road (CR 315) intersection. The site is shown in red below,
with the primary route from the Exit 94 interchange shown in blue. It is approximately 1.2
miles to the interchange from the site driveway along this route. This route and the site
define the current project area.

The subject property is a 57.9-acre site owned by SCI located in Garfield County, CO
between the Town of Silt and the City of Rifle. SCI’s Rifle Gravel Pit #1 project includes
developing this parcel into a commercial gravel mining operation. The anticipated
production over the operational life of the Rifle Gravel Pit #1 site is approximately 3
million tons of gravel which is expected to provide materials for future CDOT and
Garfield County projects. The projected duration of the commercial mining activities is 5
to 7 years. The proposed access to the site will be at the existing site driveway as
shown in Figure 1. A new CDOT Access Permit will be required for this site on CR 346
where CR 346 crosses the I-70 Right-of-Way north of I-70.
Existing Roadway, Traffic, and Access Conditions
The roadways providing access from the site to I-70 are all two-lane county roadways
with a 35 MPH Speed Limit. CR 346 (South I-70 Frontage Road) is not part of the route
but is discussed in this study and is posted at 25 MPH west of Mamm Creek Road, and
35 MPH east of Mamm Creek Road.
The site is located along CR 346 (I-70 North Frontage Road) which begins at Mamm
Creek Road on the west and ends in a cul-de-sac approximately 2.1 miles east of Mamm
Creek Road. Approximately 0.5 miles east of Mamm Creek Road, CR 346 turns from a
paved 2-lane roadway to a gravel two-lane roadway and remains gravel to the cul-de-sac
at its east terminus. The proposed access driveway to the site is located 1.1 miles east
of Mamm Creek Road on the north side of CR 346 (I-70 North Frontage Road).
CR 316 begins on the west side of Mamm Creek Road and continues westerly along the
north side of I-70 for 2.5 miles until it terminates in a cul-de-sac.
Immediately south of the Mamm Creek Road intersection with CR 346 and CR 316 (I-70
North Frontage Roads) is the ramp terminals for the eastbound and westbound I-70 Exit
94 Interchange. Continuing south of I-70, Mamm Creek Road intersects with CR 346
(South I-70 Frontage Road).
On the south side of I-70, traffic approaching Mamm Creek Road from the east or west
on CR 346 is stop controlled. On the north side of I-70, traffic approaching Mamm Creek
Road from the east or west on CR 316/CR 346 is yield controlled. There is no stop or
yield conditions on Mamm Creek Road for traffic traveling north or south bound from the
South I-70 Frontage Road to the North I-70 Frontage Road.
Existing traffic data for this study was obtained from Garfield County Road and Bridge’s
2019 Traffic Counts. Approximately 1000 Vehicles Per Day (VPD) were recorded at
nearby 2019 count locations on CR 346 south of I-70. Approximately 500 VPD were
recorded on Mamm Creek Road south of I-70. Traffic Counts for CR 346 and CR 316
north of I-70 are not available. Figure 2 shows the 2019 traffic counts, existing signing at
the intersections between the North and South I-70 Frontage Roads and Mamm Creek
Road, as well as posted speeds.

Figure 2
EXISTING TRAFFIC COUNTS, SIGNING, POSTED SPEEDS
Based upon the available traffic data, the traffic volume within the interchange is
estimated at 1250 VPD. Using a peak hour factor of 10%-15%, results in a Design Hourly
Volume (DHV) of 125-190 Vehicles Per Hour (VPH). Considering the existing volume
nearby the interchange, and the lack of development along CR 316 and CR 346 to the
north of I-70, only a very small portion of the “interchange” DHV is generated from the
north side. The anticipated volume on both CR 316 and CR 346 is significantly less than
100 VPH based upon field observations, Due to those low volumes, it was determined
that additional traffic count data is not warranted for this study.
Figure 3 shows the existing gravel access driveway (looking north) at the proposed
access location for the Rifle Gravel Pit #1 site. Figure 4 shows the site driveway viewed
from the east (looking west) with clear sight distance at the existing access for vehicles
entering and exiting CR 346 from/to the site. Figure 5 shows the site driveway viewed
from the west (looking east) with clear sight distance at the existing access for vehicles
entering and exiting CR 346 from/to the site. The State Highway Access Code (SHAC)
requires a minimum entering sight distance of 595 feet for a multi-unit truck entering a 35
MPH roadway, and a minimum sight distance of 225 feet along the roadway for a driver
approaching the access. Sight distance as measured in the field for both entering sight
distance and sight distance along the roadway is approximately 650 feet to the east and
1000+ feet to the west of the approach, which exceeds the minimums required per the
access code.

Future Traffic Volumes
Based on CDOT’s OTIS website the 20-year growth factor on I-70 west and east of the
Mamm Creek Road interchange is 1.39 and 1.32, respectively. For the study area, the
average of the 20-year growth factor between the two CDOT stations was calculated to
be 1.35. As a result of the projected duration of the commercial mining activities at the
proposed site being 5-7 years, the average 20-year growth factor was reduced to a 7-
year factor of 1.12 (1 +
.∗ 7 = 1.12 ). Using this 7-year factor of 1.12 the existing
traffic volumes were forecasted out to 2026 as shown in Figure 9.
Figure 9
2026 Forecast Traffic Volumes
Site Traffic Generation
The existing 58-acre parcel is pastureland with no crops and one irrigation ditch. The
site currently generates little to no traffic.
Future traffic generation is based on the operational plan and discussion with SCI for the
proposed Rifle Gravel Pit #1 site. Traffic will be generated from the site from two key trip
types. The first is employee trips for workers. For this analysis, employee trips are not
assumed to take place during the peak hour as peak gravel production and hauling will
take place after employees arrive and before they leave; the second is delivery of gravel
9
produced from the site. The plan for the development and operation of this site has been
split into 4 phases. A description of each phase is listed below;
Phase 1 – Site Development and Grading
· This phase of the project will include minor site grading and vegetation removal
and construction of the site access/driveway. It is anticipated that 3 employees will
be on site daily during this phase.
Phase 2 – Mining Preparation
· This phase of the project will include mobilization of the heavy equipment, work
trailer, screening and wash equipment, and major site grading to prepare the site
for mining and dewatering activities. It is anticipated that 3 employees will be on
site daily during this phase.
Phase 3 – Mining in Phases due to reclamation requirements
· This phase of the project will include gravel mining activities in quadrants, per the
code. It is anticipated that 10 employees will be on site daily during this phase.
Phase 4 – Reclamation
· This phase of the project will include reclamation of the site. It is anticipated that 3
employees will be on site daily during this phase.
This Traffic Assessment will be based upon Phase 3 of the operational plan for this site
as Phase 3 is proposed to be the highest generator of trips (hauling of produced
aggregate off the site) and the longest operational duration for the proposed pit.
The pit is expected to have a peak capacity during Phase 3 of its operation of 2000 tons
of gravel per day. A typical busy summer construction season day will yield 1500 – 2000
tons per day. A truck capacity of 23 tons/Load result in 65 to 87 daily truck loads, or 130
to 174 daily trips. This assessment will use the 30th highest daily design volume of 75
daily truck loads, or 150 daily truck trips. The gravel haul vehicles are semi-trailers with
end or side dumps and are equivalent to 3 passenger car equivalents (PCE’s). This
results in the following average daily traffic (ADT) and design hourly volume (DHV)
expressed in PCE’s
ADT: (10 Employees X 2 Trips/employee) + (150 daily truck tips X 3 PCE’s/Trip)
ADT = 470
DHV: Using a typical 10-hour daily operation results in an average of 15 truck trips
per hour x 3 PCE’s/Truck = 45 PCE’s
DHV = 45
Traffic Distribution and Assignment
All traffic generated from the site will be distributed to I-70 through the Mamm Creek Road
Interchange via CR 346 (North I-70 Frontage Road). The directional split of the site
generated 45 VPH is assumed to be 50% leaving the site onto CR 346 and entering I-70
10
via the Mamm Creek Road interchange, and 50% entering the site from the I-70 Mamm
Creek Road interchange via CR 346. Traffic distribution to/from I-70 itself is assumed to
be 50% to/from the east and 50% to/from west.
Figure 10
2019 Forecast Total Traffic
Figure 10 shows the 2019 estimated 125-190 VPH at the I-70 interchange with Mamm
Creek Road + the 45 VPH (primarily made up of heavy trucks, expressed in PCE’s)
generated from the site during peak production. The figure also shows the assumed split
of vehicles entering and exiting the site from/to CR 346 during the peak hour. The traffic
generated from the site will result in an estimated increase in traffic of 24% - 36% in the
I-70 Interchange at Mamm Creek Road during peak hour.
Figure 11 shows the 2026 forecasted 140 – 213 VPH in the I-70 interchange with Mamm
Creek Road + the 45 VPH (primarily made up of heavy trucks, expressed in PCE’s)
generated from the site during peak production. The figure also shows the assumed split
of vehicles entering and exiting the site from/to CR 346 during the peak hour. The traffic
generated from the site will result in an estimated increase in traffic of 21% - 32% in the
I-70 Interchange at Mamm Creek Road during peak hour.

Figure 11
2026 Forecast Total Traffic
Turn Lane Analysis
Based on the SHAC, a left turn lane is required on a Frontage Road highway when the
peak hour entering volume exceeds 25 VPH for highways with a posted speed under 40
MPH. As shown in figures 10 and 11, it’s assumed that during the peak hour, 50% of the
45 VPH generated by the site will be entering the site from CR 346, and 50% will be
leaving the site onto CR 346. This results in an entering volume of approximately 23 VPH
which is below the threshold of 25 VPH or more requiring a left turn lane. It is noted that,
while the left turn volume is close to the warrant volume, if warranted, the access would
meet the criteria in the SHAC, section 3.5 (5) for low opposing volume and consideration
of potential design waiver.
Based on the SHAC, a right turn acceleration lane is required on a frontage road for any
access with a projected peak hour right turning volume greater than 50 VPH when the
posted speed on the highway is greater than 40 MPH and the highway has only one lane
for through traffic in the direction of the right turn. The posted speed of CR 346 at the site
is 35 MPH and the anticipated right turning traffic volumes during peak hour are 23 VPH,
therefore no right turn acceleration lane is required for traffic exiting the site.
12
Conclusions / Recommendations
During its busiest months at full production capacity, the proposed operations of the Scott
Contracting Incorporated’s Rifle Gravel Pit #1 along CR 346 will generate 170 daily trips
(470 PCE’s). Based on the SHAC - Section 2.6(3), the increase of more than 100 trips
per day as a result of the proposed site and the increase in traffic generated by the site
exceeding 20%, the site will require a new access permit through CDOT.
Though the existing site access will be improved under SCI’s site plan, no additional
improvements are being proposed to the County road system to accommodate this
proposed site access. Special consideration should be made regarding dust control due
to hauling of produced aggregate from the site to I-70 as the first 0.6 miles of CR 346
west of the site access is gravel. It is recommended that dust control requirements, such
as the use of magnesium chloride or other approved dust mitigation methods, be included
as part of an approved CDOT Access Permit for this proposed development.
Due to the anticipated volume of heavy truck traffic during peak production and the less
than desirable sight distance resulting from the vertical profile of the North I-70 Frontage
Roads (CR 316/CR 346) as they approach Mamm Creek Road from the east or west, it
is recommended that the current yield condition for traffic approaching this intersection
from the east or west be changed to a stop condition.

Specific Development Trip Generation
Traffic will be generated based on the operational plan and discussions with the owner
for the proposed Gravel Pit. The pit is projected to have a peak capacity to produce up to
2000 Tons of gravel per day. A typical busy summer construction season day will yield
1500-2000 Tons per day. A truck capacity of 23 T results in 65 to 87 daily truck loads, or
130 to 174 daily trips. It is proposed that this assessment use a 30th highest daily design
volume of 75 daily truck loads, or 150 daily truck trips.
Project Traffic Distribution
All traffic will be distributed to the Mamm Cr Rd interchange via route described above,
from that point traffic distribution will be 50% East and 50% West.
Access Permits
New CDOT Access Permit located where CR 346 crosses I-70 ROW.
Passenger Car Equivalents
Gravel haul vehicles are semi-trailers with end/side dumps, and equivalent to 3
passenger car equivalents (PCE’s).
Peak Hour Trip Generation
Using a typical 10-hour daily operation results in an average of 15 trucks per hour, or
DHV of 45 PCE’s.
Traffic Data
~1000 vpd per Garfield County R&B nearby 2019 count locations on CR 346 south of
the interchange, estimated at 100-150 vph within the interchange. Considering the
existing volume nearby the interchange, and lack of development to the north of I-70, the
need for additional traffic data is uncertain.
Schedule
The traffic assessment will be submitted by mid-November.

The following paragraphs are excerpts of the State Highway
Access Code. These are provided for your convenience but
do not alleviate compliance with all sections of the Access
Code. A copy of the State Highway Access Code is available
from your local issuing authority (local government) or the
Colorado Department of Transportation (Department).
When this permit was issued, the issuing authority made its
decision based in part on information submitted by the
applicant, on the access category which is assigned to the
highway, what alternative access to other public roads and
streets is available, and safety and design standards.
Changes in use or design not approved by the permit or the
issuing authority may cause the revocation or suspension of
the permit.
APPEALS
1. Should the permittee or applicant object to the denial of
a permit application by the Department or object to any of the
terms or conditions of a permit placed there by the
Department, the applicant and permittee (appellant) have a
right to appeal the decision to the [Transportation]
Commission [of Colorado]. To appeal a decision, submit a
request for administrative hearing to the Transportation
Commission of Colorado within 60 days of transmittal of
notice of denial or transmittal of the permit for signature.
Submit the request to the Transportation Commission of
Colorado, 4201 East Arkansas Avenue, Denver, Colorado
80222-3400. The request shall include reasons for the
appeal and may include changes, revisions, or conditions
that would be acceptable to the permittee or applicant.
2. Any appeal by the applicant or permittee of action by a
local issuing authority shall be filed with the local authority
and be consistent with the appeal procedures of the local
authority.
3. In submitting the request for administrative hearing, the
appellant has the option of including within the appeal a
request for a review by the Department’s internal
administrative review committee pursuant to [Code]
subsection 2.10. When such committee review is requested,
processing of the appeal for formal administrative hearing,
2.9(5) and (6), shall be suspended until the appellant notifies
the Commission to proceed with the administrative hearing,
or the appellant submits a request to the Commission or the
administrative law judge to withdraw the appeal. The two
administrative processes, the internal administrative review
committee, and the administrative hearing, may not run
concurrently.
4. Regardless of any communications, meetings,
administrative reviews or negotiations with the Department
or the internal administrative review Committee regarding
revisions or objections to the permit or a denial, if the
permittee or applicant wishes to appeal the Department's
decision to the Commission for a hearing, the appeal must
be brought to the Commission within 60 days of transmittal
of notice of denial or transmittal of the permit.
PERMIT EXPIRATION
1. A permit shall be considered expired if the access is not
under construction within one year of the permit issue date
or before the expiration of any authorized extension. When
the permittee is unable to commence construction within one
year after the permit issue date, the permittee may request a
one year extension from the issuing authority. No more than
two one-year extensions may be granted under any
circumstances. If the access is not under construction within
three years from date of issue the permit will be considered
expired. Any request for an extension must be in writing and
submitted to the issuing authority before the permit expires.
The request should state the reasons why the extension is
necessary, when construction is anticipated, and include a
copy of page 1 (face of permit) of the access permit.
Extension approvals shall be in writing. The local issuing
authority shall obtain the concurrence of the Department
prior to the approval of an extension, and shall notify the
Department of all denied extensions within ten days. Any
person wishing to reestablish an access permit that has
expired may begin again with the application procedures. An
approved Notice to Proceed, automatically renews the
access permit for the period of the Notice to Proceed.
CONSTRUCTION
1. Construction may not begin until a Notice to Proceed is
approved. (Code subsection 2.4]
2. The construction of the access and its appurtenances as
required by the terms and conditions of the permit shall be
completed at the expense of the permittee except as
provided in subsection 2.14. All materials used in the
construction of the access within the highway right-of-way or
on permanent easements, become public property. Any
materials removed from the highway right-of-way will be
disposed of only as directed by the Department. All fencing,
guard rail, traffic control devices and other equipment and
materials removed in the course of access construction shall
be given to the Department unless otherwise instructed by
the permit or the Department inspector.
3. The permittee shall notify the individual or the office
specified on the permit or Notice to Proceed at least two
working days prior to any construction within state highway
right-of-way. Construction of the access shall not proceed
until both the access permit and the Notice to Proceed are
issued. The access shall be completed in an expeditious and
safe manner and shall be finished within 45 days from
initiation of construction within the highway right-of-way. A
construction time extension not to exceed 30 working days
may be requested from the individual or office specified on
the permit.
4. The issuing authority and the Department may inspect
the access during construction and upon completion of the
access to ensure that all terms and conditions of the permit
are met. Inspectors are authorized to enforce the conditions
of the permit during construction and to halt any activities
within state right-of-way that do not comply with the
provisions of the permit, that conflict with concurrent highway
construction or maintenance work, that endanger highway
property, natural or cultural resources protected by law, or
the health and safety of workers or the public.
\i1\
5. Prior to using the access, the permittee is required to
complete the construction according to the terms and
conditions of the permit. Failure by the permittee to abide by
all permit terms and conditions shall be sufficient cause for
the Department or issuing authority to initiate action to
suspend or revoke the permit and close the access. If in the
determination of the Department or issuing authority the
failure to comply with or complete the construction
requirements of the permit create a highway safety hazard,
such shall be sufficient cause for the summary suspension
of the permit. If the permittee wishes to use the access prior
to completion, arrangements must be approved by the
issuing authority and Department and included in the permit.
The Department or issuing authority may order a halt to any
unauthorized use of the access pursuant to statutory and
regulatory powers. Reconstruction or improvement of the
access may be required when the permittee has failed to
meet required specifications of design or materials. If any
construction element fails within two years due to improper
construction or material specifications, the permittee shall be
responsible for all repairs. Failure to make such repairs may
result in suspension of the permit and closure of the access.

General Prohibition – Discharges - All discharges are subject to the provisions of the Colorado Water Quality Control Act and the
Colorado Discharge Permit Regulations. Prohibited discharges include, but are not limited to, substances such as wash water, paint,
automotive fluids, solvents, oils or soaps and sediment. Contact Information: Contact the CDPHE Water Quality Control Division at
(303) 692-3500.
General Authorization - Allowable Non-Stormwater Discharges - Unless otherwise identified by CDOT or the WQCD as significant
sources of pollutants to the waters of the State, the following discharges to stormwater systems are allowed without a Colorado
Discharge Permit System permit: landscape irrigation, diverted stream flows, uncontaminated ground water infiltration to separate
storm sewers, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water,
uncontaminated springs, footing drains, water line flushing, flows from riparian habitats and wetlands, and flow from firefighting
activities. Allowable non-stormwater discharges can be found under Illicit Discharge PDD at: https://www.codot.gov/programs/
environmental/water-quality/stormwater-programs.html. Contact Information: The CDPHE Water Quality Control Division (telephone
#’s listed above).
Erosion and Sediment Control Practices - For activities requiring a Stormwater Construction Permit, erosion control requirements
will be specified in that permit. In situations where a stormwater permit is not required, all reasonable measures should be taken to
minimize erosion and sedimentation according to CDOT Standard Specifications 107.25, 208, 213 and 216 (https://www.codot.gov/
business/designsupport/2011-construction-specifications/2011-Specs/2011-specs-book). All disturbances require a stabilization plan,
native seeding or landscape design plan according to applicable CDOT Standard Specifications 212-217 and 623. The CDOT
Erosion Control and Stormwater Quality Guide (available from the Bid Plans Office at (303) 757-9313) should be used to design
erosion controls and restore disturbed vegetation.

Disposal of Drilling Fluids - Drilling fluids used in operations such as Horizontal Directional Drilling may be classified as “discharges”
or “solid wastes,” and in general, should be pumped or vacuumed from the construction area, removed from the State Highway Right
of Way, and disposed of at permitted facilities that specifically accept such wastes. Disposal of drilling fluids into storm drains, storm
sewers, roadside ditches or any other type of man-made or natural waterway is prohibited by Water Quality Control and/or Solid
Waste regulations. Small quantities of drilling fluid solids (less than 1 cubic yard of solids) may be left on-site after either being
separated from fluids or after infiltration of the water, provided: 1) the drilling fluid consists of only water and bentonite clay, or, if
required for proper drilling properties, small quantities of polymer additives that are approved for use in drinking water well drilling; 2)
the solids are fully contained in a pit, and are not likely to pose a nuisance to future work in the area, 3) the solids are covered and the
area restored as required by CDOT permit requirements (Utility, Special Use, or Access Permits, etc.). Contact Information:
Contact CDPHE (telephone #’s listed above).
Noxious Weeds and Invasive Species Management Plan – Noxious Weeds and Invasive Species guidance can be found by
contacting the Colorado Department of Agriculture (https://www.colorado.gov/pacific/agconservation/noxiousweeds) and the
Colorado Division of Parks and Wildlife (http://cpw.state.co.us/aboutus/Pages/RS-NoxiousWeeds.aspx). In either case, management
plans involving the control of noxious weeds associated with the permitted activity and cleaning of equipment will be required.
Concrete Washout - Waste generated from concrete activities shall NOT be allowed to flow into the drainage ways, inlets, receiving
waters, or in the CDOT ROW. Concrete waste shall be placed in a temporary concrete washout facility and must be located a
minimum of 50 feet from state waters, drainageways, and inlets. Concrete washout shall only be performed as specified by the CDOT
Environmental Program and shall be in accordance to CDOT specifications and guidelines. Contact Information: Contact CDPHE or
find additional information on the CDOT website: https://www.codot.gov/business/designsupport/2011-construction-
specifications/2011-Specs and refer to the specifications and their revisions for sections 101, 107 and 208.
Spill Reporting - Spills shall be contained and cleaned up as soon as possible. Spills shall NOT be washed down into the storm
drain or buried. All spills shall be reported to the CDOT Illicit Discharge Hotline at (303) 512-4446 (4H20), as well as the Regional
Permitting Office and Regional Maintenance Supervisor. Spills on highways, into waterways, any spill in the highway right-of-way
exceeding 25 gallons, or that may otherwise present an immediate danger to the public shall be reported by calling 911, and shall also
be reported to the CDPHE at 1-877-518-5608. More information can be found at https://www.colorado.gov/pacific/cdphe/emergency-
reporting-line.

CDOT has aMunicipal Separate Storm Sewer System permit, otherwise known as (MS4) from the Colorado Department of Public Health and Environment. The permit states that only stormwater can be discharged from CDOT’s storm drain system As part of the permit, CDOT has several different programs to prevent pollutants from entering into the storm drain system: Construction Site Program New Development Redevelopment Program Illicit Discharge Program Industrial Facilities Program Public Education and Outreach Program Pollution Prevention and Good Housekeeping Program Wet Weather Monitoring Program What is stormwater runoff? Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like roads and sidewalks prevent stormwater from naturally soaking into the groundWhy is stormwater runoff a problem? Stormwater can pick up debris, chemicals, dirt and other pollutants and flow into CDOT’s storm drain system or directly into a stream, river, lake, wetland or reservoir. Anything that enters CDOT’s storm drain system is discharged untreated into the waterways we use for fishing, swimming, and providing drinking water.For more information on CDOT Utility Permits: https://www.codot.gov/business/permits/utilitiesspecialuse For more information on CDOT Access Permits: https://www.codot.gov/business/permits/accesspermits For more information on CDOT Water Quality Program: Water Quality Program Manager 4201 E. Arkansas Ave. Shumate Building Denver, Colorado 80222 303‐757‐9343 Water Quality Program Industrial Facilities Program Dredged spoil, dirt, slurry, solid waste, incinerator residue, sewage, sewage sludge, garbage, trash, chemical waste, biological nutrient, biological material, radioactive material, heat, pH, wrecked or discarded equipment, rock, sand, any industrial, municipal, or agricultural waste. Tips for Reporting an Illicit Discharge Call the illicit discharge hotline at (303) 512‐4426 From a safe distance try to estimate the amount of the discharge. Identify characteristics of the discharge (color, odor, algae, etc.). Obtain information on the vehicle dumping the waste (if applicable). Do not approach! Call *CSP for illicit dumping. If possible, take a photo, record a license plate. REMEMBER: Never get too close to the illicit discharge, it may be dangerous!!!
Industrial Facilities Program Elements: 1.Educate and outreach to ownersor operators that have potential tocontribute substantial pollutant towater.2.Report and include information ondischarge and water qualityconcerns. Provide writtennotification within 15 days ofdiscovery to CDPHE.3.Submit an annual report to CDPHEcontaining the number ofinformational brochuresdistributed; name and title of each individual trained. Education There are instances when a utility company or other entity doing work in the state highway right‐of‐way will require some type of environmental permit or clearance for that work. CDOT has put together an Environmental Clearances Information Summary for those applying for a CDOT Utility and Special Use Permit or Access Permit to obtain all required clearances. This fact sheet is given to each permittee and is available at: http://www.coloradodot.info/programs/environmental/resources/guidance-standards/Environmental%20Clearances%20Info%20Summary.pdf Industrial facilities can use control measures (CM) otherwise known as Best Management Practices (BMP) during the construction of a facility and when operating the facility. Control measures are schedules of activities, maintenance procedures, and other management practices to prevent and reduce pollution entering into CDOT’s storm drain system. Control Measures also include treatment, operating procedures, and practices to control site run off which can include structural and non‐structural controls. Control Measures for Industrial Facilities CDOT defines a utility, or utility facility as any privately, publicly, or cooperatively owned line, facility, or system producing, transmitting or distributing the following: CommunicationsCable televisionPowerElectricityLightHeat GasOilCrude ProductsWaterStreamWasteStormwater not connected with highway drainageSimilar Commodity
