Attn: Molly Orkild-Larson
Re: Explanation of No Discharge at the Lafarge Cerise Pit
Dear Ms. Orkild-Larson,
Lafarge is writing to notify Garfield County of the proposed stormwater permit coverage at the
Cerise Pit. The operations on site will include aggregate mining with the possibility of a ready
mix concrete plant and a temporary portable asphalt plant. Water will be designated for
operational use within the aggregate wash plant, ready mix plant, truck wash down area and dust
suppression. The majority of the water used within the aggregate wash plant will be recycled
back through the same plant. Any water not recycled through the plant will be diverted to a silt
pond where it will be collected and recycled as needed on site. Any excess water from the ready
mix plant operation will also be diverted to the silt pond and recycled as needed. Dust
suppression will be conducted in such a way that runoff will not be generated. Additionally, the
mining operations will not expose groundwater at any time throughout the life of the mine.
Lafarge will be designing the site to keep all process water on site as described above. It is
because of this site design and reasoning that a Colorado Department of Public Health &
Environment Discharge Permit (COG -500000) is not needed.
Should you have any questions or concerns regarding this submittal please do not hesitate to
contact me at your earliest convenience by phone at 303-657-4466 or by e-mail at
Walter.Wright@Lafarge-na.com. Thank you.

PART 1
Permit - Page 9 of 23
Permit No COR -340000
13 EFFLUENT L IMITATIONS AND CONDITIONS (cont)
controls in the plan shall reflect identified potential sources of pollutants at the site. The SWMP shall clearly
describe the installation and implementation specifications for each BMP identified in the SWMP to ensure
proper implementation, operation and maintenance of the BMP. The description of stormwater quality controls
shall address the following minimum components, including a schedule for implementing such controls:
1) SWMP Administrator: The SWMP shall identify a specific individual(s), position or title within the
training organization who is responsible for developing, implementing, maintaining, and revising the
SWMP. The activities and responsibilities of the administrator shall address all aspects of the facility's
SWMP.
2) Materials Handling and Spill Prevention: Areas or procedures where potential spills can occur must have
spill prevention and response procedures identified in the SWMP The SWMP shall clearly describe and
locate all practices implemented at the site to minimize impacts from procedures or significant materials
(see definitions at Part 1.E.) that could contribute pollutants to runoff. Such procedures or significant
materials could include exposed storage of fuels, other chemicals, or waste material; and equipment
maintenance areas.
3) Erosion and Sediment Controls: Describe the BMPs that will be used to reduce erosion and prevent
sediment delivery to State waters These should include structural (such as silt fences, sediment ponds,
drop structures, check dams) and non-structural (such as mulching and revegetation) practices.
4) Other Pollution Prevention Measures: The plan shall identify any other structural and non-structural
measures for stormwater quality control on-site.
5) Preventive Maintenance: A preventive maintenance program is required, and shall involve inspection
and maintenance of stormwater management devices (maintenance of dikes separating thine drainage
from stormwater, cleaning oil/water separators and catch basins, etc.) as well as inspecting and testing of
equipment and systems to prevent conditions that could cause breakdowns or failures resulting in
discharges of pollutants to surface waters. These periodic inspections are different from the
comprehensive site evaluation (see Part 1.3 5), although the former may be incorporated into the latter.
Equipment, area, or other inspections are typically visual and are normally conducted on a regular basis
(e..g , daily inspections of loading areas).
6) Good Housekeeping: The SWMP shall identify good housekeeping procedures that will be followed by
the mining operation. Good housekeeping requires the maintenance of a clean, orderly facility. This part
of the SWMP shall address cleaning and maintenance schedules, trash collection and disposal and
collection practices, grounds maintenance, etc.
7) Identification of Discharges other than Storrnwater: The stormwater conveyance system on the site shall
be evaluated for the presence of discharges other than stormwater, such as imine drainage, spoil springs,
sanitary waste, or process water of any kind. The SWMP shall include a description of the results of any
evaluation for the presence of discharges other than stormwater, the method used, the date of the
evaluation, and the on-site drainage points that were directly observed during the evaluation
A number of discharges other than stormwater may not require a CDPS Industrial Wastewater Discharge
permit and are considered Allowable Non-Stormwater Discharges Any of these discharge that exist at
the site must be identified in the SWMP.. See Part I.B.8 of the permit for the list of such allowable
discharges
3. BMP lm lementation acrd Design Standards
Facilities must select, install, implement, and maintain appropriate BMPs, following good engineering, hydrologic and
pollution control practices. BMPs implemented at the site must be adequately designed to provide control for all
potential pollutant sources associated with industrial activity to prevent pollution or degradation of State waters.

1 INTRODUCTION — NEW PERMIT
This is a new stortrrwatei' discharge general permit- It incorporates the slot inwater provisions front the Division's Sand and Gravel
Alining and Processing (and Other Nonmetallic Minerals Except Fuel) General Permit (COG -.500000). That permit covers both
process water and slorvnwater discharges Permit COG -500000 will be renewed separately and will addresses additional pollutants
of concern, such as selenium Due to the expected complexity of the renewed permit, the Dh'isiorl determined that .sand and gravel
operations that only discharge slormwater could be covered under a separate stormwater-only discharge permit.
A11 existing sto,mwater-only dischargers covered under the COG -300000 permit_ who have reapplied, will he automatically
transferred to coverage under this nein permit (CUR -340000), and will be assigned a 17ei1' permit certification number
This permit is fbr the regulation of stormwater discharges associated with sand and gravel mining operations (The permit also
coveys other nonmetallic minerals except fire!; all references to sand and gravel ii'ill include the outer minerals, unless specifically
exempted Dedicated asphalt and concrete batch plants and recycling areas at these facilities may also be covered) This rationale
will explain the activities and discharges that are covered under this permit, how to apply for coverage under the permit: and the
requirements Of the permit
The forms discussed in the rationale and permit are available on the Water Qualitj' Control Division's website at.

II. CHANGES IN THIS' GENERAL PERMIT
This permit incorporates the stormwater provisions from the Division's Sancl and Gravel Mining and Processing (and Other.
Nonmetallic Minerals Except Fuel) General Permit (COG -50000()). However, there have been several notable changes from the
COG -.500000 permit, which have been incorporated into this permit. Significant changes are listed below. Numerous. other minor
changes, including revisions to the order of sections, were made far clarification purposes only
A. Permit Coveraze
New Permit: As discussed above, this is a new permit, although it incorporates most of the provisions from the Division's
existing Sand and Gravel General Permit. Only discharges of storrnwater are covered.
Concrete and Asphalt Recycling>: The list of facility types that are covered by the permit has been expanded to include the
recycling of concrete and asphalt (when done consistent with the activity descriptions for Standard Industrial Classification
(SIC) Code 14). This type of activity has been routinely covered udder 1111.5 permit; the additional language fbrurtalizes this
practice
B- Application Requirements
The permit application requirements have changed slightly, including the addition of an email address, if available See Part

II CHANGES IN THIS GENERAL. PERMIT (cont )
C General Limitations
Several additions and clarifications were made to this :section. -
1 Bulk Storage: Genet al requirements scar bull; storage structures fbr petroleum products and other chemicals were
clarified to state that secondary containment or equivalent adequate prosection is required
2 Erosion Prevention: A statement was added cIa i/i'ing that call stormwater shall be discharged in a planner to prevent
e1'051017, Scorning. Or damage to str'ecnn banks, slreambeds, or Aches
D Stormuater Management Plan (SiJ'MP)
The SII'MP Contents .section has been modified. Some of the changes are Limited lo organization of information, which does
not require modification r}f an existing permitlee's current S!-VAIP. A'fost of the SWMP changes involve either clarifications,
re/ormaltinSg, or adopting requirements from the Division's other stormwatergeneral permits (e g., BMP installation
specifications) For e.ri.sling permittees (i.e. , those with permit coverage under permit COG -500000 before September 30,
2007), their SAINT must be amended to include the new required items.
For existing permittees, any SWAJP changes based on the change in permit requirements must he completed by March 1, 2008.
The plan is not to be submitted to the Division unless reque-sted, but must be available on site as outlined in Part 1 B.7 b of the
permit.
1 Site Map: The list of items needed for' the Site Map has been elpanded, in order to adequately' chat acterize the site A list
of items caul factors has been added to the section on idemi/ving potential stornrwatel pollutants, in order to clarifi1 the
Division's intent in this area This requirement may necessitate changes to existing permittees' SW111Ps.
Description of Potential Pollutant Sources: The requirement to idemi/i' Potential Pollutant Sources has been expanded t0
include more details for the evaluation of such VOW ces This evaluation allows for the appropriate selection of BMPs /Or
implementation at 0 facility or site This requirement may necessitate changes to existing perinittees'SWVMPs.
3. SlornnvaterManagement Controls: This section has been modified to require that the SWMP provide installation and
implementation specifications for each BMP identified in the SI'I'A'IP For Structural BMPs, in most cases, this must
include a technical drawing to provide adequate installation specifications. See Part I B.2. c of the permit. Sections have
also been added requiring that preventive maintenance and good housekeeping measures be included in the SWN1P
Preventive maintenance is critical to ensuring the success of the BAfIPs at a site. Good housekeeping measures are a
Co177111017 sense means of increasing compliance with the permit. This requirement may necessitate changes to existing
permittees' S11'i1Ps.
E Stornnvater Discharges - BMP Implementation and DesiQn Standard&
Part 1 B.3 of the permit reiterates the requirement that facilities select, install, implement, and maintain appropriate BMPs,
following good engineering, hydrologic' and pollution control practices. This part also requires that BMPs must be adequately,
designed to prevent pollution or degradation of State waters. Additional language was also added to Section VI. C of the
rationale discussing these BMP requirements and further clarifi'ing the expectations fhr conlphance with this permit.
F Consistency with Other Plans
.1.section has been added clan ifiring that other documents, .such as an SPCC, can be used to meet some of the SI-I'MP
requirements, provided that the other documents ore readily available and the SMWP includes appropriate cross references

accordance with Part I.C.h o/ the permit. However, any inspection reports that are submitted to the Division must follow the
signatory requirements contained in that .section.
A Permit Termination Criteria
A .section has been added providing details on the criteria, fire terminating permit coverage Sites that are covered hr a bond
under the Colorado Division of Reclamation. Alining, And Safety, or CDRMS will need to prove that bond release has
occurred before permit coverage can be terminated Sites that are not under a CDRMS bond must provide additional
information before the permit can be terminated
111 SIORA'flWATER PROGRAA/1
As required under the Clean Water Act amendments of 1987, the Environmental Protection Agency (EPA) has established a
framework for regulating municipal and industrial stotnnvater discharges This framework is under the National Pollutant
Discharge Elimination System (NPDES) program. (Note: The Colorado program is t'elerred to as the Colorado Discharge
Permit System, or CDPS, instead of NPDES.) The Water Duality Control Division ("the Division') has slortmvater regulations
(5CCR 1002-61) in place. These regulations require specific types of industrial facilities that discharge stormwaler associated
with industrial activity (industrial stormwater), to obtain a CDPS permit for such discharge The regulations specifically
include sand and gravel mining activities as industrial facilities. Facilities that discharge industrial stoi mwaler either directly
to surface waters of indirectly, through municipal separate storm sewers, must be covered by a permit.
IIS COVERAGE UNDER THIS PERMIT — INDUSTRIAL CATEGORIES

defined in CDPS regulations (5CCR 1002-61) as man-made orlon -induced, or natural alteration of the physical, chemical,
biological, and radiological integrity of water. Utilizing industry -accepted standards for BIiIP selection that are appropriate
/br the conditions curd pollutant sources present, will typically be adequate to meet these criteria However, site -.Specific
design, including ongoing assessment of BMPs and pollutant sources, is necessary In ensure that BIi1Ps operate as intended
The permit further requires that storlmyaler discharges from industrial activities shall not cause, have the reasonable potential
to cause, or measurably contribute 10 an excuision above any water quality standard, inc'luchng narrative standards for' water
quality This condition is the basis fir' all CDPS Discharge permits, and addresses the need to ensure that waters of the State
maintain adequate water" quality, in accordance with water quality standards, to Continue to meet their designated uses. 11 is
believed that, in most cases, B1LIPs can be adequate 10 meet applicable water quality standards If It ate,. quality impacts are
noted, of the Division otherwise deter iniltes that additional permit requirements are necessary, they are typically imposed as
follows. 1) at the renewal 01 this general permit or through a general permit specific to an industrial sector (if the issue is
sector -based): 2) through direction from the Division based 011 the implementation of a TA4DL (if the issue is watershed -
based), or 3) if the issue is site-specific, through a revision to the certification from the Division based on an inspection or
SWMP review, or through an individual permit
D Other- Requirements.
1. Facility Inspections: The permittee will he required to snake a thorough inspection 01 their- .stormwcater management
_system, at least ht'ice per year (in the spring and Jall). (See Part I.B.5 of the permit fin alternate schecltiles) These
inspections must be documented and summarized in the .Annual Report to the Division

Jill CHANGES AFTER PUBLIC NOTICE
Written comments were received from the Colorado Rock Products Association during the public notice period Response t0 these
comments is discussed below
fJ Comment. The permit requires that existing permittee -s update their SJVifPs. if necessary, to i17c'a7 porate additional
requirements for the site map, description of potential pollutant sources, and s1o1mwafe1 management Controls The
deadline for this update is February 1, 2008 It was requested that pe1171111ee% be allowed additional time to complete the
update, as some entities hove numerous sites (See Pari 1.13(2) of the permit )
Response: The SWAP change -s are not extensive, and are not expected to require .substantial time to complete. However.
the deadline was evended 10 March 1, 2008.
B Comment. The permit requires that, far'inost sites. inspections of the facility's slormwatei-management system is required
twice a year, in the spring and fall. 11 was requested that the permit not specific an exact tiro el ame for these inspections.
(See Part 1. 13(5) of the permit )
Response.- The :spring and fall tinmefi-antes were included so as to avoid haying the two required inspections conducted too
close together The permit has been changed to state that the twice yearly inspections are required apps oxhnwell, in
spring and fall If this is notpo.ssible. the inspections must be conducted at least 120 days apart Note that at least two
inspections must .5011 be conducted within each calendar year, and reported on the following Annual Report.
Comment The permit requires that a copy of the SWA'IP be retained an .site, for active mines, and mines undergoing
reclamation It was requested that, for sites undergoing reclamation, the SWAMP be retained by the permittee, but not
necessarily on site. (See Parti B(7)(b) of the permit)
Response. The t eason for maintaining the St1'IWP 00 -site is to ensure that the plan is readily accessible to those who are
working on the site (such as BMP installation and maintenance skiff), as well as to state and local inspectors. This is the
default requirement, and is expected to be feasible of the vast majority of sites The permit has been changed to allow for"
111e SWMP to be retained at another location, provided that it is approved 17y the Division The allowance far an alternate
location is intended far Specific circumstances, 10 take into account operations that clo not have a suitable on -:site location
where the S1b1IVP may be maintained.
D Comment.- The per'nlit states that the Division has the authority to require continued permit coverage, even if the site has
been reclaimed if the Division has shown or has reason to .suspect that the stormwater discharges may contribute to a
violation of a water' qualify standard It was. requested that the Division include C1 rationale fol, this provision. (See Part
1.D(2) of the permit.)
Response. This provision. part Of Regulation 61, Colorado Discharge Permit Regulations, .section 61.3(7)(e)(vii), is
standard in all stormit'aler discharge permits. It gives the Division the discretion 10 require permit coverage whenever
water quality standards may be feopaldi=ed, regardless of the source. No changes were oracle to the permit
F Comment. The permit authorizes access t0 the site b,v the Division, EPA. and/or their authorizedrepresentative(s).
Concerns were raised regarding safety, liability, and insurance issues, if inspectors access the site without nolifyrnglnining
personnel, or access the site without the required training or escort (See Part 11. B(1) of the permit )
Response. Although the Division understands the concerns included in the comment, the comment addresses Division and
EPA procedures and iS therefore outside of the scope of the per mit. No changes were made 10 the permit.

Recurrence
INTRODUCTION
Spill Prevention, Control, and Countermeasure (SPCC) plans for facilities are prepared and
implemented as required by the U.S. Environmental Protection Agency (U.S.EPA) Regulation
contained in Title 40, Code of Federal Regulations, Part 112, (40 CFR 112). A non -
transportation related facility is subject to SPCC regulations if: the aggregate aboveground
capacity of the facility exceeds 1,320 gallons (excluding those tanks and oil filled equipment
below 55 gallons in capacity) or if the aggregate underground capacity of the facility exceeds
42,000 gallons (excluding those that are currently subject to all of the technical requirements of
40 CFR Part 280 or all of the technical requirements of state programs approved under 40 CFR
281); and if, due to its location, the facility could reasonably be expected to discharge oil into or
upon the navigable waters or adjoining shorelines of the United States.
An SPCC plan is not required to be filed with the EPA, but a copy must be available for on-site
review by the Regional Administrator (RA) during normal working hours. The SPCC plan must
be submitted to the US EPA Region 8 RA and the state agency along with the other information
specified in Section 112.4 (a) if either of the following occurs:
1. The facility discharges more than 1,000 gallons of oil into or upon the navigable waters
of the United States or adjoining shorelines in a single spill event; or
2. The facility discharges oil in quantities greater than 42 gallons in each of two spill events
within any twelve-month period.
The following spill information must be submitted to the RA within 60 days if either of the
above thresholds is reached. This report is to contain the following information (112.4 (a)):
1. Name of the facility.
2. Name of individual submitting the information.
3. Location of the facility.
4. Maximum storage or handling capacity of the facility and normal daily throughput.
5. The corrective actions and/or countermeasures taken, including adequate description of
equipment repairs and/or replacements.
6. Descriptions of the facility including maps, flow diagrams, and topographical maps.

Cerise Pit
SPCC Plan
7. The cause(s) of such spill(s), including a failure analysis of system or subsystem in which
failure occurred.
8. Additional preventive measures taken or contemplated to minimize the possibility of
recurrence.
9. Such other information as the Regional Administrator may reasonably require that is
pertinent to the plan or discharge(s).
The SPCC plan must be amended within 6 months whenever there is a change in facility design,
construction, operation, or maintenance that materially affects the facility's spill potential. The
SPCC plan must be reviewed at least once every 5 years and amended to include more effective
prevention and control technology, if such technology will significantly reduce the likelihood of
a spill event and has been proven in the field. All such amendments must be re -certified by a
registered professional engineer (PE).
If the owners and operators of a facility that are required to prepare an SPCC plan and are not
required to submit a Facility Response Plan, the SPCC plan should include a signed certification
form, provided in Attachment A (per Appendix C to 40 CFR 112).

Cerise Pit
SPCC Plan
GENERAL DESCRIPTION
The Cerise Pit is a sand and gravel mining, processing and storage operation that includes mining
pits, aggregate stockpiles, conveyor systems, and office/storage trailers. Portable crushing and
washing plants may be brought on site as needed. These portable plants will have their own
SPCC plans to account for control measures in place and the hydrocarbons associated with their
activities. Situated within the pit there will be a ready mix concrete facility and possibly an
asphalt plant.
* The following list of equipment is only a preliminary example of what could be located on site.
As the proposed plans are finalized through the permitting process changes to this list may occur.
Fixed and Mobile Storage [112.1(d)(2)(ii)]:
AST 1— Diesel Tank
AST 2 — Diesel Tank
AST 3 — Gasoline
(-4) Drums in containment area

—25,220 gallons
112.7 (a)(1)
This facility is in general conformance to the SPCC Regulation, which became effective on July
17, 2002.
112.7 (a)(2)
In complying with all applicable requirements of the SPCC Regulation, no deviations were
employed or claimed in this Plan.
112.7 (a)(3)
Once the facility design is finalized, Figure 1 will include the location of the tanks and general
arrangement of the facility. Also provided on the diagram will be the storm water flow
directions (and spilled oil paths). As required under this section, the facility diagram will
indicate the location and contents of each container.
112.7 (a)(3)(i)
The main oil storage at the facility is the two 10,000 -gallon diesel tanks and one 5,000 gallon
gasoline tank as listed above. There will be approximately 4 drums on site as well within proper
secondary containment. t* As the proposed plans are finalized through the permitting process
changes to this list may occur.)
112.7 (a)(3)(ii)
The Cerise Pit will use several measures to prevent storm -water runoff or spills and other
pollution from reaching the navigable waters of the United States. Those measures include both
structural and non-structural controls.
8
Cerise Pit
SPCC Plan
Cleanup materials and supplies shall be kept stocked and shall be located near all oil -storage and
handling areas. At least one person, whether a Lafarge attendant or a delivery contractor, shall
be continuously present during all fueling and oil -transfer operations. Oil -storage tanks shall be
checked routinely to establish the volumes of materials in storage at the facility.
The liquid level in each tank shall be measured prior to filling to ensure that there is sufficient
capacity in the tank for the planned oil delivery; use a direct -vision gauge or its equivalent (e.g.,
a dipstick) to estimate the volume of fuel. All piping connections shall be properly secured and
inspected before transfer pumps are turned on. Drivers shall conduct visual inspections before
departure; the inspections shall include a close examination of the lowermost drain and all outlets
to ensure that caps are tight and properly adjusted, and that they will prevent liquid discharges
while in transit.
Fuels and oils shall be poured or pumped carefully to prevent spilling and over -filling.
Employees shall visually inspect the area following all fueling and oil -transfer activities.
Lafarge employees shall promptly clean up drips and small spills.
112.7 (a)(3)(iii)
Loading and unloading of fuels will occur within the pit area. Drainage will be such that all
spilled material would remain in the pit area, thereby serving as secondary containment.
112.7(a)(3)(iv)
The facility's countermeasures for discovery of a discharge will ensure rapid discovery of leaks
or spills. They are based on awareness training, inspections, and site security.
The facility's countermeasures for response to a discharge are designed to ensure rapid and
appropriate responses to leaks or spills and that the health and safety of employees and the public
are protected. They are based on response training, Lafarge's internal notification procedures,
and ensuring that access to the spill area is restricted.
Emergency -Response Contractors have been established and agreements include approved
emergency -response contractors to deal immediately with large spills. Spill kits will be utilized
to clean-up minor spills. The facility's countermeasures for cleanup of a discharge will ensure
that all areas and media affected by the spill are identified, that the health and safety of
employees and the public are protected, and that the cleanup actions will protect the quality of
surface and groundwater resources.
112.7(a)(3)(v)
Materials recovered during spill cleanup must be properly contained until it is determined
whether they can be recycled through on-site processes or disposed of offsite. The decision
between the two will depend on the types and quantities of fuels or oils spilled; types and
quantities of materials recovered during cleanup (i.e., contaminated soil or water); and
concentrations of oil products in the recovered materials. Offsite disposal of contaminated
materials may be recycled through a nearby Lafarge hot plant, through a vendor, or an
appropriate landfill. The Lafarge Management (Operations OR Environmental) must pre -
approve all disposals of spill cleanup materials.

presented in Attachment E for bulk storage containers and ancillary equipment. All aboveground
bulk storage containers for fuels, oils or oil products shall be included in the integrity -testing
program. The facility does not have any piping that is subject to integrity testing requirements.
As required and deemed necessary, integrity testing shall be performed on a regular schedule,
and following all material repairs or modifications. Appropriate repairs shall be undertaken
whenever a tank or other equipment fails an integrity test. Records of all integrity testing shall
be kept with this Plan. Visual inspections are performed regularly according to the procedures,
and include inspection of tank supports and foundations. Inspections will be recorded on a
monthly basis and will be maintained for 3 years.
112.8 (c)(7)
There will be no internal heating coils at this facility that contain oil.
112.8 (c)(8)

INTEGRITY TESTING ATTACHMENTS
As required and deemed necessary, Lafarge will perform integrity testing on oil containing
Aboveground Storage Tanks (ASTs). The tests will be performed on a regular schedule and
whenever material repairs are made. This testing will use one of the following testing methods
such as hydrostatic, radiographic, ultrasonic, acoustic emissions, or another system of non-
destructive shell testing.
Lafarge will perform ultrasonic shell testing as the method used for testing the ASTs integrity.
Lafarge will likely use an A&D Company's Ultrasonic Thickness Gage (AD -3253) or an
equivalent ultrasonic device. The testing will be performed on a regular schedule that will be
based upon the condition and age of the each AST. The records of integrity testing will be kept
with this plan.
