(1) Completed Application Form:
A completed application form along with a check in the amount of $250 was submitted to the
City of Rifle on October 28,2006. A copy of that submittal is included in Attachment A.
LafargeWest, Inc. completed the form as the developer for the proposed sand and gravel
extraction operation and conveyor bridge river crossing. North Bank Holdings LLC is the owner
of the property. Lafarge and North Bank entered into a gravel property lease on May 27,2005,
and are co-applicants on the Garfield County Special Use Permit Application.
(2) Proposed activity description:
North Bank Holdings, LLC (North Banks) has partnered with Lafarge West, Inc. (Lafarge) to
create a wildlife preserve and riparian area along the Colorado River approximately 2.2 miles
east of the City of Rifle. The project encompasses approxim ately 237 acres and is located in
Section 12, Township 6 South, Range 93 West, Garfield County, Colorado. Lafarge would
construct two lakes, with a water surface area totaling 70 acres. The sand and gravel resources
extracted, in order to create the lakes, would be conveyed across the river to Lafarge's Mamm
Creek site for processing. North Banks andLafarge entered into a Gravel Property Lease dated
May 27,2005 for 20 years.
Extraction of the sand and gravel resources from the site will be by conventional open pit
methods employing scrapers, front-end loaders, track hoe, trucks, if necessary, and farm
implements for reseeding and reclamation. No explosives will be needed to create the lakes.
The mining operation would be regulated by the Colorado Division of Reclamation, Mining and
Safety (formerly the Division of Minerals and Geology). Lafarge submitted a mining permit
application to the Division and received approval on October 3,2006.
The planned operation will consist of dry mining the gravel by initially constructing a dewatering
ditch around the perimeter of each of the proposed lakes and installing a pump that will dewater
the sand and gravel pits and return the water to the Colorado fuver through existing sloughs on
the property. Water discharge permits will be obtained prior to beginning operations on the site.
Construction of the two lakes is expected to generate approximately 450,000 tons per year of
sand and gravel, depending on local market and economic conditions. The products will be used

in normal construction activities such as road base, pipe bedding, and asphalt and concrete.
production. No other commodities will be produced as a result of the planned extraction.
The operational life of the mine is estimated at 12 years, which allows for 9 years of production
and 3 years for release of the reclaimed site. Construction will start with the western portion of
Cell B. Then the mining of Cell B, which will occupy 3I acres, will commence. Once the sand
and gravel reserves are removed from Cell B, the construction of the lake will be initiated and
the ground water allowed to filI the lake with water. Finally, construction wiil start on Celi A.
This cell will consist of 47 acres. Upon completion of the gravel extraction, Cell A would be
restored as a lake in conformance with the mining plan approved by the DRMS.
Each of the cells will be stripped in internal phases of approximately I 5 to 20 acres each. The
initial phase will require that the stripped overburden be placed in stockpiles for later utilization
in the reclamation. Subsequent internal phases will be stripped just prior to completion of
mining of the preceding phase with the stripped overburden being placed directly into the
previous phase. This sequence will be repeated as each internal phase is completed and a new
intemal phase is opened up.
Based on exploration borings completed in the fall of 2004, the North Bank property on average
contains approximat ely 2 to 5 feet of overburden, 1 8 to 25 feet of sand and gravel, and is
underlain by shale. The proposed operation will remove the overburden, stockpile it for
reclamation, and extract all of the sand and gavel to the bedrock shale. The banks of the pits
would be back-filled with overburden to form a 3:1 slope.
Mining activities would occur at the site during daylight hours only, with 30 rninutes on either
side for start-up and shut-down activities. Maintenance may occur during non-daylight hours.
Recovered material would be conveyed over the Colorado River to the current processing plant
located at the Mamm Creek site. The only skuctures planned for the site include a conveyor and
other ancillary processing equipment. The extraction and construction site itself is outside the
10O-year floodplain. The conveyor, where it crosses the river and islands, is within the
floodplain. The conveyor would be appropriately elevated above the ground surface where it is
in the floodplain to assure passage of the 100 year flood.
(3) 2 Sets of Plans and Specifications:
The required information and maps that are referenced below are included in the mining
application submitted to the Colorado Division of Reclamation, Mining and Safety (DRMS,
formerly the Division of Minerals and Geology) which is enclosed in Attachment D.
(a) Vicinity map with site location and legal description: Refer to Exhibit B for vicinity
map and Exhibit A for legal description.
(b) Property Boundary Lines: Refer to Exhibits Cl and C2
(c) Location of any buildings or structures within 50 feet of proposed activity: Refer to

(g) A statement of amount and location of any matter proposed to be deposited in areas
other than that shown on plans -There will not be any matter deposited in areas
outside the disturbance boundary of the proposed project. Additionally, there will be
no matter deposited in the floodplain.
(h) Nature and location of existing vegetation and affect of proposed activity on
vegetation: Refer to Exhibit J1 for existing vegetation and Exhibit F for affect of
proposed activity on vegetation.
(i) A vicinity map: Refer to Exhibit B
(,) Location of 1O0-year floodplain: Refer to Exhibit C2
(4) Document identifying any activity that may present or create a foreseeable risk to the
City's waterworks or pollution to the City's water supply and measures to obviate such
risks.
The plarured activities will pose no threat to the City of Rifle's water supply. First of all, the
sand and gravel resources which will be extracted in order to create the lakes will be conveyed
across the river to Lafarge's Mamm Creek site for processing. The extraction and construction
site itself is outside the 1O0-year floodplain and causes no deleterious effect to the Colorado
River or the surrounding floodplain.
The conveyor, where it crosses the river and islands, is within the floodplain. The conveyor is
designed to have greaseless rollers and a system to scrape off material from the belt before it
cycles around. These controls will greatly minimize the potential for oils and earthen material to
fall offthe conveyor and into the Colorado River. The conveyor bridge system consists of two
suspension bridges and an elevated conveyor truss over approximately 700 feet of the braided
Colorado River system and two islands. One suspension bridge will span the northern branch of
the river and be approximately 150 feet long. A second suspension bridge will span the main
branch of the river and be approximately 250 feet long. The remaining 300 feet of islands and
southern overflow channel of the river will be spanned by an elevated conveyor truss with
supports every 50 feet or so. All supporting structures are located outside of the floodway.
Refer to Attachment B for conveyor bridge drawings.
The conveyor and bridges will be well hidden from the public view because of the topography
and large Cottonwood trees. The conveyor system is a temporary use for the duration of the
mining activity. Upon cessation of mining, the entire system will be removed and the ecosystem
will be restored to its previous state. The conveyor was designed in accordance with the
recommendations established in the "Mamm Creek Gravel Pit Colorado fuver Floodplain Study''
and subsequent detailed analysis of the necessary scour protection (reference High Country
Engineering letter dated June 9,2006). This study determined the minimum low chord elevation
to allow the Base Flood to pass without any deleterious effect to the 100 year floodplain.
Furthermore, the study determined the minimum scour depth and recommended the size and
depth of riprap to be used on the supporting structures. All recommendations of this study will

City of Rifle Watershed Permit Application
McBride Proposal Summary
Lafarge West, Inc. is proposing to mine sand and gravel at a location approximately 2.2
miles east of Rifle, Colorado. The subject properly lies between U.S. Highway 6 and the
Colorado River, and encompasses approximately 200 acres. The properly is within
portions of Section 12 in Township 6 South, Range 93 West. Lafarge has a Gravel
Properly Lease, with North Bank Holdings, LLC, on the subject properly through June
2025. The properfy is directly across the River from Lafarge's Mamm Creek operation.
Lafarge intends to mine the subject properfy and convey material over the Colorado
River to the current processing plant located at the Mamm Creek site. The conveyor is
planned to have greaseless rollers and a system to scrap off material from the belt before
it cycles around. These controls would greatly minimize oils and earthen material from
falling into the river. There would be three separate bridges over the braided river system
to span the river and two islands. The largest bridge would be over the main channel of
the river. The conveyor and bridges are expected to be fairly well hidden from the public
view because of the topography and large Cottonwood trees in the area.
A diesel powered generator would provide power to conveyor and other processing
equipment. Any petroleum onsite would be managed in accordance with EPA
regulations. The site would have a Spill Prevention PIan to prevent, control and address
petroleum spills. Site would also have process water and stormwater discharge permits to
manage water leaving the site.

EXHIBITD-MiningPlan
Introduction
Mining at North Bank Resources will be by conventional open pit methods employing
scrapers, front-end loaders, track hoe, trucks, if necessary, and farm implements for reseeding
and recla,ration. The planned operation *ill "o'sist ;f dry mini-ng the gravel by initially
constructing a dewatering ditch uro.tnJ-*'" perimeter of each of the proposed lakes and
installing a dewatering pump that will dewater the sand and gravel and return the water to the
ColoradoRiverthroughanexistingsloughontheprop.:p.Noexplosiveswillbeneededto
extract the sand and gravel resources. ifr" "p.t",ion
will produce nitural sand and gravel and
crushed stone which will be used in ,rormul construction activities such as road base' pipe
bedding, etc. and asphalt and concrete frodrction' No other commodities will be proCuced as
a resuliof the planned mining operation'
Delvatering
Dewatering will be accomplished by using a dewatering pump that will be relocated as mining
progresses in each cell. Based on the cuient Mamm ireek tperations' the dewatering rate is
expected to be on the order of 250 gallons-per-minute (gpn ), when the dewatering pumps are
active. In order to alrow for the seasonal variations in water inflow, a 1,000-gpm pump will be
utilized. Dewatering water rvill be discharged according to an approved plan into existing
sloughs in order to rJurn the rvater to the colorado River system.
Minins
As ilrustrated on EXHIBIT c, mining wiil occur on the rower terrace approximately 10 feet
inside of the break in slope between the upper and lorver terraces' This l0-foot buffer will
allow access around the entire p"ri-"i", ;;',h. proposed pit lake and mining area and also
provide a "margin of safety" should any of the'overburden from the upper terrace migrate
down slope.

pit. The access road, overl*d "orrr.yo.
,ou,irg, and ttmporary placement of overburden
stockpiles will occuiwithin the 1gg-foot buffer. ln order to ensure that no material enters the
river system a silt fence will be construcled and maintained along this side of the operation'
on the eastern end of cell A and the rvestern end of ceil B, where a gas well and pipeline are
anticipated to be, a buffer of l5 feet on each side ofa centerline ofthe access road or a 30-foot
corridor will be observed as dictated li,i* g."technical stability report which is located in
APPENDX A of this application.

should mining commence prior to the
construction of the gas well and gas pipeline, the area between Cells A and B will be mined to
recover the sand ,.?-g.ur.t ana"reuuiit with overburden and pit run to accommodate the gas
well and pipeline.

The proposed operation is expected to average approximately 450,000 tons per year, depending
on local market and economic conditions (conditions to date at neighboring operations indicate
low-production ranges of 200,000 to 300,000 tons per year and high-productions ranges of
600,000 to 750,000 tons per year), and therefore, the expected operational life is approximately
12 years. This allou,s for 9 years of production and 3 years for release of the reclaimed site.
Material w-ill be processed from two distinct pits; Cell A and Cell B. Cell A occupies
approximately 47 acres and Cell B 31 acres, respectively. The proposed operation will start
with the western Cell A, and completely mine it out prior to mining of Cell B. Each of the
cells will be stripped in internal phases of approximately 15 to 20 acres each in order to allow
for efficient removal of the resources, minimal "double-handling" and stockpiling of
oi,erburden, and concurrent reclamation. The Cells will be mined to a 0.5:1 slope and
overburden replaced into the pit to create a2:l to 3:1 slope depending on proximity to the
u,ater elevation. Scrapers or other similar earthmoving equipment will be utilized to rentove
and stockpile the overburden for later use in reclamation of the site. Front-end loaders and/or
backhoes and trucks, when necessary, will be used to mine the sand and gravel and deliver it to
the primary crusher. The initial phase ra,ill require that the stripped overburden be placed in
overburden stockpiles for later placement as part of the reclamation plan.
With the addition of the overburden stockpiles and roads, it is anticipated that approximately
35 acres of total disturbance ra,ill occur. Subsequent intemal phases will be stripped justprior
to completion of mining of the preceding phase rvith the stripped overburden being placed'
directly into the previous phase. This sequence u,ill be repeated as each internal phase is
completed and a new internal phase is opened up.
Based on exploration borings completed in the fall of 2004, the North Bank property on
average contains approximately 2 to 5 feet of overburden, I 8 to 25 feet of sand and gravel, and
is underlain by shale. Approximate quantities are as follows:
Processing
Tlie proposed operation will utilize Lafarge West Inc.'s N,Iamm Creek Mine's processing
facilities and scale house. A prirnary crusher will be located adjacent to the active mining area,
from the primary crusher, the sand and gravel will go by conveyor across the Colorado fuver to
North Bank Resources

EXHIBIT E- Reclamation Plan
The North Bank property currently contains the following types of vegetative cover:
Saline bottomland shrublands
Irrigated pasture and hay fields
Riparian and wetland
The primary land uses are rangeland and agricultural. Sorne recreational uses such as fishing
and hunting currently occur. The reclamation plan calls for the largest portion of the site to be
open-water lakes. The pits will be allou,ed to filI with water to approximately the current water
table level by both ground u,ater, natural runoff, and by agricultural return flows from the
Lower Cactus Valley Ditch. The post-mining land uses will be sirnilar to the current land use
and does not conflict u,ith adjacent Iand uses, which are currently comprised of agriculture,
pastureland, gravel mining, wildlife habitat, and gravel pit lakes.
As stated in EXHIBIT D, the sand and gravel pits will be mined to a 0.5:l slope and backfilled
to a 3:l overall slope to 10 feet below the water surface. Thereafter, slopes will be graded to
2:l to the lake bottom. Any excess fill that is available will be used to reclaim roads, etc and/'or
used to create an irregular lake bottom and edge. Large tree -root balls, if available on site and
removed as a result of mining, will be added to the bottom of the lakes prior to filling to add to
the aquatic habitat.
Disturbed areas around the pit lakes u,ill be graded and reseeded u'ith approved seed mixes in
order to promote a natural appearance and minimize erosion. A portion of the excess
overburden will be utilized to build small islands, coves and wetland sheh,es around the lake
edge to create palustrine emergent and submergent habitat. Riparian habitat is expected to
develop within approximately 18 vertical inches above the water surface and within
approxlmately 12 inches below the water surface. Riparian areas will be seeded with
hydrophytic species to provide additional fish and waterfowl habitat. Approximately 3.3 acres
of ripirian u."u, *" expected in Cell B and 1.7 acres in Cell A as a result of the reclamation
grading and seeding. Upland areas will be seeded with upland species to provide grassland and
shrubiand habitat. Approximately 5.6 acres of upland are expected around Cell B and2.7 acres
around Cell A. Approximately 25.2 acres open water habitat are expected in Cell B and 40.4
acres in Cell A. The basic revegetation concept is to seed native vegetation types that are
similar to those present. In addition, a weed lnanagement plan u,ill be administered until bond
release is granted in order to control regrowth of any noxious rveeds.
EXH[BIT F is a plan rnap that illustrates the proposed reclamation plan and Table E-1 details
the material balance required to complete the reclamation of the pit lakes according to the
above narrative.

As evidenced by the above table, the site contains sufficient material to reclaim the pit slopes
and any other areas such as roads, stockpile locations, etc.
As mentioned in EXHIBIT D, topsoil and/or overburden material will be salvaged prior to
mining and placed a minimum of 12 inches in depth. Any topsoil and/or overburden piles that
will remain in place for more than 12 months will be seeded with oats, Western wheatgrass,
and Intermediate wheatgrass to stabilize the pile and protect it from erosion.

EXHIBIT G - Water Information
North Bank Holdings, LLC is the owner of significant water rights that will be used to cover
the majority of the iniicipated water use and augmentation requirements of the proposed sand
and gravel tperation. Thlse water rights exist in the form of agricultural water that is delivered
to th-e property via the Stobaugh Didh and Eyre Ditches. Both the Stobaugh and Eyre Ditches
terminate on the North Bank property and excess water is returned to the Colorado River via
sloughs on the property. A brief description of these water rights is as follows:
1. 1.75 c.f.s., absolute, from the Stobaugh Ditch, Priority No. 17, decreed by the
Garfield County District Court in Civil Action No. 103 for 4.0 c.f.s., with an

LafargeWest, Inc. and North Bank Holdings, LLC intend to apply.to-the.State Engineer's
OfficJ (SEO) to change the above rvater rigtrts from agricultural to industrial use and apply
these changed water .igt tr to our augmentati,on plan in order to meet the operational needs and
Iong-term Ivaporation-requirements of the planned lakes. In support of this proposed change,
Lafarge West, Inc. has prepared the folltwing analysis of water use at the North Bank
property.

Identi{ication and Location of Water Wells rvithin 600 feet of the Property
A search of the SEO's database for u,ater wells, their location, and owners was completed and
the results are attached to this EXHIBIT. The proposed operation lies down gradient from all
adjoining property with u,ater wells. The large distance to neighboring water wells, rvith the
exteption of in. two water wells on the properfy, should result in no impacts to these water
rvells. In the case of the two water wells on the property, one is owned by North Bank
Holdings, LLC and the other by Mr. John McBride. The proposed operatiorr is still down
gradieni from these two wells and little impact is anticipated; however, North Bank Holdings,
LLC has obtained an agreement with Mr. John McBride concerning his water well and the
planned operation.
Calculation of Augmentation Water Requirements
It is assumed that the required augmentation plan will be based on offsetting future depletions
to the Colorado River reiulting from the gravel pit operations and evaporation with historical
consumptive use associated tvith the dry-up of approximately 93.5 acres currently being
irrigated by the Stobaugh and Eyre ditches and conversion of a portion of the water rights to
permanentiy augment for the resultant lakes. The following details the planned consumptive
use of water by component for the proposed operation:
Evaporative Losses
Since the miling is to be "dry mining", and the lake surface will not be present throughout a
majority of the y"*, no separate calculation has been completed for the exposed water in the
dewateiing ditches, as the surface area of the ditches is insignificant when compared to the
planned like surface area. As a consen,ative estimate of augmentation requirements, North
bank Holdings, LLC has assumed that the lakes will be present for the entire year and
calculated the augmentation requirements accordingly. Evaporation calculations according to
the SEO's method for Pond and Lake Evaporation at elevations less than 6,500 feet abol'e
mean sea level for the Rifle Colorado area are as follows:
NOAA Atlas gross annual evaporation
Net annual precipitation for Rifle
Net Evaporation
Annual evaporation
Planned maximum lake size

EXHIBIT H - WildHfe Information
The proposed North Bank Resources consists of about 237.67 acres, more or less, of shrub
land, irrigated pasture and riparian floodplain forest on the north bank of the Colorado River
b,.gilG ;pproximately 2.2 miles east of fufle, Colorado: T.6 S., R 93 W', Sec' 12, 6th PM,
Garfield county. The properry is bordered in its entirety on the southem edge by the Colorado
River and by the Rio Grande Westem Railroad on the northern edge'
The current land use is mainly year-round pastureland for grazir,g cattle and horses' The fields
are irrigated during the summer months as needed. Tamarisk, Russian olive, and plains
cottonwood trees intermittently line the area next to the Colorado River with the greatest
concentration in low lying or floodplain areas'
Fish and Wildlife
Fish and wildlife species presence on the North Bank Resources site are related to the
vegetation and habitats present on the project site.
Habitat TYPes
Wildlife habitat present on the North Bank Resources site corresponds to the vegetation types
discussed in other sections. Predominant wildlife habitats consist of greasewood shrub land,
i*ig"i.at hayfields-g razed pasture, and riparian-wetland
_
areas along the floodplain of the
Colorado River. ttt-e greasewood shrub tand ls intermixed with various upland grasses, weeds
and barren areas. The upland pasture habitat is degraded and heavily grazed by cattle and
horses. The riparian-wetiand haUitat has been degraded by grazingand invasion of non-native
vegetation, ,r"h u, tamarisk and Russian olive trees. This vegetation type fgrms a continuous
linear band of habitat along both riverbanks and on numerous islands within the river'
Table H-1 provides a list of potential rvildlife on the project area based on reports from
adjacent sites and a field reconnaissance conducted in early October 2005. Table H-2 plovides
u iirt of 13 potentially occurring Threatened and Endangered Species listed by the U'S' Fish
and Wildlife Service (USFWS) foi Garfield County. These lists of species are not
comprehensive and do not include many summer breeding, winter, and fall migrant species'
The following subsections provide brief description of wildlife that may potentially occur on
the site.
Big Game
Big game species potentially occurring on the North Bank Resources Site include mule deer
(oiJcoileus h".nio,rus), white-tailed dier (Odocoileus virginianus), and American elk (CerrTrs
elaphus). Mule deer are the most common big game species found on the project site' White-
tailed deer and elk occasionally visit the area in limited numbers. Ir4ule deer occur on the
project site throughout the yeai, typically concentrating in lush native vegetation u'ithin the
Colorado River floodplain.

important travel coffidors for local deer. The floodplain provides important mule deer u'inter
habitat and a good source offood and cover for local year-round resident deer. The floodplain
also provides winter range for elk'
Raptors
A database search of the cDow wildlife Resource Information Service indicates that 13
species of raptors (Ui.as of pr.y; potentially occur in Jh9 vicinity of the Norlh Bank Resources
Site. These include bala "ugfe'dfaliaeetus
leucocephalus), golden eagle (Aquila chryseatos),
Swainson,s hawk (Buteo siainsoni), red-tailed hawk (Bjamaicensis), rough-legged hawk
(B.lagopus), northern harrier (Circus .y*.ur), melfin (Falco columarius)' American kestrel
(F.spanerius), cooper's hawk (eccipiter "oop.iii;,
Sliarp-shinned hawk (A' striatus)' Northern
goshawk (A.gentilis), great-horned owl (guUo uitgi"iul*) and long-eared owl (Asio otus)'
ldany of these ,p..i.r-*" infrequent ,p.ing and fil.migrants that occasionally pass through
the Colorado River Valley. A site ,""or*uirJ*ce conducted in October 2005 did not locate any
raptors or active nests on the project site. However, dense riparian areas and tall mature
cottonwood trees on the south Uant<-of the Colorado River providi potential nesting habitat for
Cooper's hawks, sharp-skinned hawk and red-tailed hawks'
Game Birds and Waterfowl
Upland game birds potentially occurring on the Nortlr Bank Resources Site include ring-
necked pheasant (Phasianus colchicus)] mourning dove (Zenida macroura) and turkey
(Meleagris gallopavo). Mouming dore u.rd turkey tv-ere observed on the adjacent site during a
site reconnaissance. Both of these species prefei mountain brush and riparian habitats with a
high degree of vegetation diversity and available water' Brood producticn of doves is
correlated with spring precipitatio, urJ dependent,on th.e availability of seeds and accessible
rvater. No game birJs-or thiir nests *,"r" tbr"tved on the site during the site reconnaissance
visit conducted in October 2OO5.None of tl're other upland game species are expectedto occur
on the project site.
The Colorado River and its associated floodplain and wetland areas provide habitat for
breeding and migrant waterfowl. Waterfowl liklly to occur on the North Banh Resources Site
include: Canada geese (Branta canadensis), common and red breasted mergansers (Mergus
merganser, M. serrator), gadwall (anas strepera), American widgeon (A'americana)' mallard
(A.platyranchos), green-winged teal la.crecca;,'blue-*inged teal (A'discors)' cinnamon teal
(A.cyanopteral, no.tlrern shJveler (a.clypeata), pintail.(A'acuta), redhead (Aytha americana)''
canvasback (A.valinsineria), lesser t"u"p (A.marila), common goldeneye (Bucephala

the great blue heron (Ardea herodias). A heron communal rookery of approximately 25 nests
was located in large cottonwoods on the southern bank of the Colorado fuver, just west of the
project site. Although the herons had migrated away frog the rookery by September' the site
'i, uppur.ntly active and produced sever-al young in 2005' During the site reconnaissance
conducted in October 2OO\, red-wing black UirarlAg.laius phoniceus) were the only species
seen utilizing cattail dominated v,'etlands along the Colorado fuver'
Small Game and Furbearers
The only small game species likely to occur on the project site is the Nuttal's cottontail
(iylvila[us nuttat-iiiy. T^his species can occur in all habitats on the project site,'but is most
common in shrubbi vegetation and within the floodplain riparian habitat. The Nuttal's
cottontail, along *ith n.rmerous rodent and ground squinel species are potential prey for
numerous raptors and a variety of terrestrial predators expected to occur on or near the site'
Predators and other furbeareis likely to occur on site include: American beaver (Castor
canadensis), muskrat [Ondu,ru zibethicus), mink (Mustela vison), ermine (M'erminea), badger
(Taxideataxus),ru".oon(Procyonlotor),redfoxfliulpeswlpes)andcoyote(Canislatrans)'
No small furbearers were' observed on'ihe ,it" during the site reconnaissance conducted in
October 2005. Coyote tracks and scat were observed'
Threatened and Endangered Species
The project site could have potentially provided habitat for a number of Threatened or
Endangered Species (T&E Species) in thl past. However, because the existing site is degraded'
has been continuousl y grazed *d alter"d by human activity, is outside the range of many
species listed, o. ,p""1"", have been historically eradicated from the area, the Bald Eagle is
likely the only species that could utilize elder cottonwoods and riparian-wetland habitat along
the Colorado River.
Refer to Table H-2, rvhich provides a
Endangered Species listed by the U'S'
County.
list of 13 potentially occurring Thieatened and
Fish and WilaUfe Service (USFWS) for Garfield
Summary
Since tlie Norlh Bank property occurs on the north bank of the colorado River, contains few
mature cottonwood or other large trees, and is east of the most sensitive habitat areas located
on the southern barik of the Colorado River, the project is not likely to have any significant
impact or interaction with sensitive, threatened oi endangered wildlife habitat. Additionally,
the mining limits will be offset 100 feet from the river, thus preserving mostof the riparian'
wetland, aquatic and other habitat along the river corridor that may be utilized by T&E
Species. iequential rnining and reclailation will reduce the impact to any potentially
occurring species at any given tirne during the course of the project' Mine reclarnation will
provide
"nijt
", qruiiry lpiand and additional open water and wetland habitat than currently
exists on site.

EXHIBIT I - Soils Information
This exhibit presents information on soils present within the 237.67-acre site. Information
presented in this section is based on the published Soil Su_rvey of Rtfle Area, Colorado: Parts of
barfield and llesa Counties (Soil Survey) (SCS 1985): and observations made by Walsh
Environmental staff during a siie visit in october of 2005. This exhibit includes descriptions
of the general soil-mappirig units, their morphology, and the physical characteristics of the soil
series found on the ,ii.. figrt. I-1, Vegetaiion Mup, shows the physiographic composition of
the site and Iocation of the soil types described below'
Soil DescriPtions
Within the project area, one general soil-mapping unit occurs, the Arvada-Tonifluvents-Heldt
complex. T-his-map unit contains deep, well drained to somewhat poorly drained, nearly level
to gently sloping soils on benches, terraces, alluvial fans and floodplains. Heldt soils have not
U"Jr, *upped on this site and are replaced by Wann soils as described below. These soils are
typically used for irrigated crops, giazing, urd *itdlif. habitat. Major crops are alfalfa, small
grains and irrigated pasture.
An,ada Series
Arvada soils are on benches, terraces, and fans. They are deep, well drained, and alkali affected
soils formed in alluvium derived from sandstone and shale. The surface layer is apale brown
loam about 3 inches thick. The subsoil is strongly alkaline brown silty clay loam about 14
inches thick. The substratum is a light brown oi bro*, silty clay loam to a depth of 60 inches'
permeability is very slow. Organic mafter content of the surface layer is low. Surface runoff is
medium and the erosion hazard is moderate. Slopes are 1 to 20 percent. Native vegetation on
this soil is typically alkaline tolerant saltgrass, aikali sacaton and greasewood. The suitability
of the Arvada soils for irrigated crops is poor because of their saline-alkali condition and low
permeability.
On site, this series is directly corelated with the uppel most terrace located adjacent to the
railroad corridor. The soil ciraracteristics and vegetation documented in the Soil is consistent
with those observed on site. This area of the site is dominated by greasewood with a minor
grass component. This portion of the site is not used as irrigated pasture'
Wann Series
The Wann series consists of deep, somewhat poorly drained soils that formed in alluvium
derived from sandstone and shale. The upper part of the surface is typically dark grayish brown
sandy loam about 8 inches thick. The lower part is dark grayish brown fine sandy loam about 4
inches thick. The upper part of the underlying material is mottled, light brownish gray fine
sandy loam and rundy loam about 24 inches tt i.t . The lower part of the underlying material is
mottie light brownish gray coarse sandy loam to a depth of 60 inches. Permeability is
moderatJy rapid. Su.fuce runoff is slow and the erosion hazard is moderate. Depth to the rvater
table ranges from 2 to 3 feet and varies u,ith the amount of irrigation water applied to the soil
and surrJunding soils. Slopes are 1 to 3 percent. Native vegetation on this soil is typically

alkaline tolerant saltgrass, alkali sacaton, wheatgrass, sedges and rabbitbrush. Tile drains and
improved water **-ugrrn.rt increase crop potential of Wann soils as this soil is usually
inigated by furrows and flooding inigation.
on site, the wann Series occurs on a middle terrace between the upper Arvada and lower
Torrifluvents terraces. The soit characteristics and vegetation documented in the Soil Survey is
consistent u,ith those observed on site. This area of the site is dominated planted pasture
grasses, salt grass, and abundant weeds. This area has been used as inigated pasture and is in a
itate of drying out following session of flood inigation practices.
Torrifiuvent Series
Torrifluvents occur on floodplains and lorv terraces adjacent to the Colorado River' They are
deep and well drained to somewhat poorly drained soils^formed in alluvium. These soils are
stratified and 'ary widely in texture and depth. The surface layer ranges from Joamy sand and
fine sandy loam io silty ioam and clay loam. The underlying layers are generally sandy loam or
loam stratified with sand, gravel and cobbles. These soils are subject to flooding' Slopes are
.
nearly level between 0 todpercent. Native vegetation is mainly cottonwood, willow, tamarisk,
water tolerant grasses, sedge and rushes. The iuitability of Tonifluvents for irrigation and most
other uses is pJor because-of flooding, a high \.\'ater table and its salinity and alkalinity'
Torrifluvents are fairly suitable for wetland wildlife habitat.
On site, the Torriflut ent Series is directly correlated with the Colorado fuver floodplain, the
lowest terrace located on the site. The ,oil .h*u.teristics and vegetation documented in the
Soil Survey is consistent with those observed on site. This area of the site is dorninated by a
riparian-wetland plant community and has been fenced to preclude cattle and grazing'

EXHIBIT J - Vegetation Information
Tlris exhibit presents information on the vegetation and habitat types present within the237.67-
acre site based on observations made by Walsh Environmental staff during a site visit in
October of 2005, and USGS topographic mapping, State of Colorado Natural Areas Program
Native plant Revegetation Guide for Colorado, and National List of Plant Species that Occur in
Wetlands. This exhibit includes descriptions and characterization of the plant communities,
the dominalt species found in the upiand and riparian habitats present and their overall
condition.
The plant communities present on the North Bank Resources site are directly related to the
topography, soils, hydrology, aspoct, climate and human activity'
Vegetation TYPes Present
As illustrated on Figure J-I, based on topography, the site is divided into three distinct areas:
an upper, rniddle ana nooaplain terrace consisting of saline bottomland shrublands, irrigated
pasture, and riparian-wetland plant communities, respectively. Approximate areas of each plant
community type are summarized in Table J-I.
Table J-l
Summary of Plant Community Area and Potential Impacts
Note: Areas are approximate
Saline Bottomland Shrublands (Upper Terrace)
This portion of the site will not be impacted by the proposed mine operation. A majority of the
,pp"i terrace of the site is vegetated with xeric saline bottom shrubland species. This portion of
the site also includes varioui atypical landscape species planted around farm structures and
intemal roadways. Dominant grais species such as inland salt grass (Distichlis spicata) and
basin wildrye (Leymus cinerus) that are typically present in this type of habitat are minimal.
Barren ground is prevalent, giving rise to noxious weed invasion. This portion of the site is in
poo, .ondition. Dominant species found on the upper terrace of the site include:

Irrigated Hayfields-Grazed Pasture (Middle Terrace)
This portion of the site is where mine operations are proposed. The middle terrace is vegetated
with typical rangeland and hay/straw producing species that have been continuously flood
irrigated and grazed. Pasture species composition shifts between cattle rotation/hay production
units. Unpalatable species such as saltgrass and noxious weeds are prevalent due to
overgrazing. This portion of the site is in very poor condition.

investigated. Riparian habitat present has been degraded by grazing and invaded with noxious
weeds, such as tamarisk and Russian olive trees.
The following is a brief description of the riparian-areas investigated, vegetation, soils and
hydrology. These areas are outlined and labeled on Figure J-1, Vegetation Map.
l. East Drainage and Riparian Areas: This unnamed drainage shows up on USGS
mapping as an intermittent stream that crosses and collects irrigation water from the Lower
Cactus Valley Ditch. This drainage and associated riparian areas flow south through the
upper and middle terraces into the Colorado River. This drainage is located along the
eastern property boundary and moves in and out of the site boundaries. This area is flanked
by xeric and pasture species mentioned in previous sections. Riparian vegetation is present
on low-lying saturated benches and is intermittently present where the charurel banks are
steep and constricted. This drainage/riparian areas are characterized as follows:

3. Stobaugh Ditch: Stobaugh Ditch is located in the middle terrace. The remnant of this
ditch present on site flows across the center of the site diagonally from east to west into
the Colorado River.
During an interview with Mr. Scott Balcom, Esq., Walsh discovered that the Stobaugh
Ditch has been abandoned/cut-off due to upstream erosion problems at the diversion
point on the Colorado fuver. Subsequently, alternative points of diversion were
lstablished to irrigate grazing pastures through direct pumping from the Colorado
River. The remaining isolated segment of the ditch on the Site contains said return florv
from these diversions, recent precipitation, and seasonal tail water emanating from
regional flood inigation to the north. The ditch is a depression area and has sustained
hydrology during the irrigation season to support rvetlands in the bottom and along the
banks. Riparian habitat is of very poor quality. This ditch rr,etland is characterized as
follows:

4. Central Drainage and Riparian Areas: This unnamed drainage shows up on USGS
mapping as an intermittent stream that crosses and collects irrigation water from the Lower
Cactus Valley Ditch. This drainage is a natural channel that conveys drainage basin and
upstream return flows to the Colorado River. It enters the site in the central part of the
nLrthern boundary, and then flows in a southerly direction until it meets the middle terace.
At this location, the natural drainage has been channelized to a stock pond and then into the
Colorado River. Although this drainage has been rnodified to suit flood irrigation needs, it
still functions to convey any natural drainage of the basin. This drainagelripatian area is

runs- in a southerly direction toward, but not directly into Colorado River. This drainage
contains riparian habitat in the upper terrace. However, where it meets the middle terrace,
soil saturation and wetland vegetation diminish. A lateral ditch is present to pick up and
convey any periodic water to the flood irrigated pastures and property to the west of the
Site. This drainage/riparian area is characterized as follows:

Much of the site and its vegetation are influenced by flood irrigation practices and a network of
connected, discorurected and convoluted drainage ditches that artificially distribute surface
water, return flow and tail water, creating marginally wet areas in once dry, upland meadows.
Tlrese areas, after being heavily grazed and persistently wetted are dominated by a mixture of
saltgrass and noxious weeds with a minor component of "wetland" species such as Baltic rush
(Juncus balticus), corrrmon tluee-square bulrush and other upland/pasture species as outline

The reclamation plan will involve the follorving major reclamation activities
i) Backfilling of pit wall to a 3:1 slope to 10 feet below the lake surface and2:l to the
pit floor
2) Crading and seeding of the side slopes and disturbed areas, other than roads.
3) Revegetation of the disturbed areas according to the approved reclamation plan and
using an approved seed mixture.
4) Demolition and./or removal of any buildings, scales, tanks, etc.
Since the planned operation will result in two separate pit lakes and the pit lakes will be rnined
in phases of approximately l5 to 20 acres in size, and reclamation of the pit banks rvill proceed
as soon as possible after mining in order to minimize "double handling" of overburden,
reclamation costs have been calculated based on the assumption that the maximum disturbance
will be for a single pit lake. Table L-l details the reclamation plan by activity and estimates
the associated costs for the reclamation plan.

EXHIBIT S - Fermanent Man-made Structures
As of the Cate of this submittal, the only man-made structures within the proposed permit
boundary are barb-wire fences, lwo houses, a barn, and corrals. Adjacent to the north side of
the property is a Burlinglon Northern Santa Fe railroad track. The houses and railroad tracks
lie more than 200 feet fiom any planned mining and./or disturbed areas. Only the bam, corrals,
and barb-wire fences iie within ihe planned diiturbance area. Additionally, there are planned
oil and gas well pad sites within tire permit boundary and disturbance area' The sites are
located on the enclosed Exhibits u""oriing to the lease and have been taken into account for
the planned operation..
In order to ensure the safety and stability of these structures, the permitees commissioned
Greystone Environmental Consultants of D-enver, Colorado to complete-a-geotechnical stability
study of the planned pits and associated structures. Complete copy of this study is presented
in APPENDIX A of this permit application
The attached geotechnical study makes the following recommendations concerning setbacks

RE: Stope Stability Anatysis for Gas Well Pads and Access Roads at
Lafarge North America, Mamm Creek Pit.
Dear Mr. Rozelle:
Greystone Environmental Consultants (Greystone) has completed its stability
ana-lysis of multiple slopes associated with the construction of gas well pads and
access roads in the Mamm Creek Pit near Rifle, Colorado (Figure 1). The gas
well pads measure 200-feet-by-300-feet; average 25feet high; and have finished
sicie slopes of 3:1.
The soil characteristics of each gas well pad will be dictated by the timing of the
progression of the mine plan and the construction of the gas well pads. Figure 2
illustrates these two cases, Case A and Case B. Case A gas well pads will be
constructed after mining is complete. These well pads will be built using stripped
and stockpiled clayey, sandy overburden. Case B gas well pads will be
constructed before mining excavation. These well pads will be built using well-
graded in-situ sand and gravel bolstered with 3H:1V side slopes constructed of
the same clayey, sandy overburden used in constructing the Case A well pads.
The timing of mining activities, gas well pad construction, and approval of this
technical revision do not allow for a clear determination of the case of each well
pad. Hou,,ever, based on the material properties, CaSe A would have a higher
potential for slope failure and will be considered as worst-case-scenario for all
well pads.

OBJECTIVE
The objectives of these analyses are:
1. To evaluate the stability of constructed slopes associated with gas well
pads and access road; to achieve a safety factor of 1.5 for static loading
and 1.3 for seismic loading;
2. To determine classification and suitability of stripped overburden to be
used aS backfill for gas well pad and access road construction; and
3. To determine the effects of varying unit weight, internal friction angle, and
well pad height to the stability of tne slope for Cased A and B.
,
ASSUMPTIONS
Scenarios
Two cases exist based on the timing of mining activities and gas well pad
construction:
case A - Mined Areas - Gas well pads constructed after the area has
been stripped, excavated and mined. Gas well pads and
associatei slopes will be constructed using clayey, r-rldy
overburden stiipped and stockpiled on-site as part of the mining
process.
Case B - Unmined Areas - Gas well pads constructed'before the area has
been stripped, excavated and mined. Gas well pad slopes will be
construcied using clayey, sandy overburden stripped and
stockpiled on-site as part of the mining process'
Due to the timing of mining activities, gas well pad construction and the approval
of this technical revision, the appropriate case associated with each gas well pad
is unclear; therefore, case A and B will be applied to all gas well pads and
slopes.

place material and overburden backfill. The virgin sand and gravel, Case B,
represents the gravel pit wall or unCisturbed bank. lt has a thickness of
approximately i5 feet, and is classified as well-graded sandy gravels (GW). The
overburden fill, Case A, is classified as clayey gravely sands (SC) and represents
the material to be used to construct the gas well pads and access roads where
needed. To further classify the material, the Hazen Uniformity Coefficient and
Coefficient of Gradation were catculated based on soil boring logs provided by
Lafarge. Both materials were found to be well-graded and non-uniform in particle
size distribution. Additionally. both materiats were assumed to have no cohesion.
Construction Methods
ln Case A, the gas vrell pad will be constructed after the area has been stripped,
excavated and mined. The gas well pads and slopes will be constructed using
overburden backfill placed via truck and shovel, using the pit floor as a base. A
dozer will be used to create side slopes of 3:1. Wheel compaction of the gas well
pad and side slopes is assumed for these analyses. The pit floor is composed of
shate bedrock. Average depth-to-bedrock at the Mamm Creek Pit is
approximately 25 feet.
ln Case B, the gas well pad will be constructed before the area has been
stripped, excavited and mined. An area 200-feet-by-300-foot will be cleared and
graded to create a flat, level area for the drilling and construction of the gas well.
As mining and excavation activities approach, a setback of 1O0-feet from the gas
well will be maintained, to a highwall slope no greaterthan 0.5:1 as required by
the Colorado Department of Minerals and Geology (DMG) Permit #N2000113-

As soon as feasible, overburden backfill will be placed against the highwall and
graded to decrease the highwall to a minimum 3H:1V slope.
Other AssumPtions
One distributed load was identified for these analyses. A distributed load of
130,000 lbs, or 97.7 lbs/sq ft, was assumed for a typical Rig 99 gas well drill rig
as provided by Antero Resources corporation (Antero). The weight of the gas
weil and associated equipment was negligible and therefore not included in these
analyses.
For both cases, because of the close proximity to the Colorado River and the
post-mining reclamation plan to convert the gravel pits to lakes, the gas well pads
are assum"o to be fully saturated, having a piezometric surface equal to the
height of the gas well fad. lt is important to note, that as the pits fill with water
the"slope staditity will increase because of the hydrologic pressure exerted by the
weight of the water on the sloPe'
PROCEDURE
The stability analyses were performed using the simplified Bishop's Method
lCAf-eNn Stop" btunitity Anatysis System, Version ? lOl Three types.of slope
iailure were analyzed: toe circie failure, slope circle failure, and base circle
failure. Results are shown on Figures 3 through 16. Multiple analyses were run
for case A and case B, using a range of parameters, to determine the slope
stability sensitivity to changei in unit weight, internal friction angle and thickness
of material or well Pad height'
Although there is a low potential for seismic hazards in Rifle, colorado, a worst-
"ur"-.i"nario
(seismic ioading of 0.1 g peak ground acceleration) was assumed
as provided by the United States Geological Survey (USGS) Hazards Mapping
Program.

CONCLUSION
Based upon these analyses, conservative assumptions, and the information
available, the gas well fads and access roads slope safety factors are as follows:
Case A - Factors of SafetY
Static Loadinq Seismic Loadino
Toe Circle Failure
Slope Circle Failure
Base Circle Failure
Toe Circle Failure
Slope Circle Failure
Base Circle Failure

Case B - Factors of SafetY
Static Loadinq Seismic Loadinq
Base circle failure is unlikely to occur due to the shale bedrock base' The full
rungu of safety factors with parameters are attached as Tables 1 through 3' All
safJty factors ieported are sufficient to ensure the stability of these slopes;
gilatLr tnen 1.5 for static loading and greater than 1.3 for seismic loading.
LOditionaly, the stability of the stopes will increase as the water level in the pit
rises.

INTRODUCTION
Spill prevention, Control, and Counterneasure (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 ll2, (40 CFR 112)' A non-
transportation related facility is subject to SPCC regulations if: the aggregate aboveground
"upu.ity
of the facility.*...dr 1,3i0 gallons (excluding those tanks and oil filled equipment
beio* i5 gallons in capacity) or if the aggregateunderground capacity of the facility exceeds
42,OOO gullor. (excluding tirose that are currently subject to all of the technical requirernents-of
40 CFR part 280 or all of the technical requirements of state programs approved under 40 CFR
2g l ); and ie 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 Uy itre 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 h\ if either of the following occurs:
1. The facitity 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
Z. The facility discharges oii 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 rvithin 60 days if either of the
above thresfrolai is reached. This report is to contain the following information (112'4 (a)):
1. Name of the facilitY.
2. Name of individualsubmitting the information'
3. Location of the facilitY.
4. Maximum storage or handling capacity of the facility and norrnal daily throughput.
5. The conective actions and./or countermeasures taken, including adequate description of
equipment repairs and/or replacements.
6. Dlscriptionr of th. facility including maps, flow diagrams, and topographical maps.

failure occulred.
g. Additional preventive measures taken or contemplated to minimize the possibility of
recurTence.g. 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 pror.i-in the field. All such amendments must be re-certifred by a
registered professional engineer (PE)'
If the owners and operators of a facility that are required to prepare an f e-cc plan and are not
required to submit a Facility Response plan, the sicc plarshould include a signed certification
fo;, provided in Anachment A (per Appendix c to 40 cFR 112).

Lafarge will perform integrity testing on oil containing Aboveground Storage Tanks (ASTs).
The tests wili 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 williikely use an A&D Company's Ultrasonic Thicloress Gage (AD-3253) or an
equivllent ultrasonic device. The tesiing will be performed on a regular schedule that will be
basea upon the condition and age of the each AST. The records of integrity testing will be kept

Current amount of infested land to be managed: approx- 40 acres
100 ft buffer around mining area to include all disturbed soils and burms
Re-vegetation will consist of seeding all reclaiming burms and slopes
Lafarge has contracted Mountain Valley Ventures for our annual 2004 weed management
prevention program, also we are working with Steve Anthony to implement the Garfield
County conservation districts weed cost share program for all three Lafarge Pit locations
located within Garfield County.
Starting April and every month thereafter:
Herbicides will be used as the primary application and prevention for weed management.
Application records will be available for inspection and will be forwarded to Steve
Anthony
Alternative N{ethods of treatment will include when permissible, burning watering
ditches and dewatering pond areas, otherwise mowing and cutting will be done.

SECTION 1
Description of Industrial Activities
This SWMP has been prepared for the North Bank Pit, which will produce aggregates for use at
construction sites in the Garfield County, Colorado vicinity. FIGURE I identifies the general
location of the facility, as well as the nearest receiving waters. Construction activities present at
the site are as follows:
I GRADING/NIINING
Site is leveled and smoothed according to final project specifications using a road grader.
Material may be excavated using earthmoving equipment and processed through various
feeders, screens, and crushers. This may include right-of-ways, drainage ditches, and
road sub-base areas ofthe project.
N QUARRYING
Drilling and blasting is used to liberate virgin stone from its natural consolidated state.
Haul trucks are typically used to take the material to the plant for processing.
I srocxrll,rNc (Check if applicable). OVERBURDENAND TOPSOI
Stockpiles may occur in the form of earthen berms.
. SAND AND GRAVEL
Raw and/or processed aggregates are stockpiled for future use.
o AGGREGATE MIX FOR CONCRETE PRODUCTION
Aggregate can be stored in stockpiles, and loaded into a ground hopper as needed, and
then conveyed to the plant. Material may also be loaded directly into a series of hoppers
located above the plant that directly discharge into the plant.
o AGGREGATE MIX FOR ASPIIALT PRODUCTION
Raw material can be stockpiles or put into storage bins.
o RECYCLE ASPHALT PRODUCT
Asphalt that is being stored and/or processed for reuse.
o RECYCLE CONCRETE PRODUCT
Concrete that is being stored and/or processed for reuse.
tr ASPHALT MILLING
The existing roadway is milled, emptied into haul trucks and hauled off-site.
tr ASPHALT PAVING
Hot mix asphalt is transported to the project from a production plant located off-site. It is
then placed, compacted and rolled according to project specifications.
North Bank Pit
Storm Water Managernent Plan

I
I tr AS PIIALT MANUFACTURING
A hot-mix asphalt plant blends together aggregate and asphalt cement_to produce a hot,
homogeneous asphalt paving mixture, which is then hauled to off-site construction
projects. The aggregate used can be a single material, such as a crusher run aggregate or
u pit .* material, or it can be a combination of coarse and fine aggregates, with or
without mineral filler. The binder material used is normally asphalt cement but can also
be an asphalt emulsion or one of a variety of modified materials. Various additives,
including liquid and powdered materials, can also be incorporated into the mixture'
Activities at these sites may include the following: raw material unloading into
stockpiles or storage tanks, raw material feed to plant, material batching, raw material
storage ur"4 .".yJlable asphalt disposal areq truck wash out, and water supply and
settling lakes.
READY MIXED CONCRETE, CENTRAL BATCHING
These operations mix sand, gravel, cement, and water together to form ready mix
concrete, which is then hauled to off-site construction projects.
The raw materials are made up of sand, gravel, cement, water and additives. The sand
and gravel is either stored in siockpiles located outside and fed into the plant via loaders
and -onveyors, or it is stored directly in a series of hoppers located directly above the
central plant. The remainder of the raw materials is stored in tanks to protect them from
exposure to moisture and temperature until they are pumped into the mixer. Once the
raw materials are fed into the central mixer and combined to form Ready Mix concrete,
the final product is placed within trucks and removed from the site.
READY MIXED CONCRETE, DRY BATCIIING
These operations apportion out a mix of sand, gravel, cement, and water together, which
is then mixed within the truck to form Ready Mixed concrete that is hauled to off-site
construction proj ects.
The raw materials are made up of sand, gravel, cement, water and additives. The sand
and gravel is either stored in stockpiles located outside and fed into the plant via loaders
and ionveyors, or it is stored directly in a series of hoppers located directly above the
central plant. The remainder of the raw materials is stored in tanks to protect thern from
"*por*" to moisture and tanperature until they are pumped into the mi1er. Dry batching
then apportions out and dumps the raw materials into the concrete truck-mounted mixer
where-ii is continually agitated and mixed to keep it from hardening before it arrives on
the assigned job site.
EQUIPMENT FI]ELING
Diesel and./or gasoline tanks are located on site for fueling of equipment. OFsite
vendors refill tanks as needed.

tr EQUIPMENT MAINTENANCE
The site contains a shop area where necessary maintenance can be conducted for site
equipment. Tlpical chernicals associated with maintenance, such as used oil, antifreeze,
-tto, oil, hydiaulic oil, brake fluid, etc, may be stored on site as needed- All chemicals
are stored in such a manner as to prevent materials from mixing with stormwater or being
accidentally discharged off site or to waters of the U.S.
SECTION 2
Site Map
Enclosed is FIGURE l: Site Vicinity Map and FIGURE 2: Site Map; which indicates site-
specific characteristics and BMPs implemented. The site has been determined to be within a
single drainage area. The site comprises approximately 238 acres. The site is currently used for
cattle grazing. When mining begins soil berms will be constructed along all sides of the property
to serve to prevent run-on from adjacent property. The property has an overall gentle slope to
the southwest toward the Colorado River which runs along the south property border. Several
holding ponds will be constructed to provide storage for storm water when the site becomes
active.
Currently storm water will be conveyed across the undisturbed surface to one of rwo ditches
running approximately northeast to southwest and and roughly dividing the property into thirds.
The ditches discharge into the Colorado River. Two discharge points will be located along the
Colorado River near the current discharge points of the existing ditches. Directions of
stormwater flow, location of all surface water bodies, inflow areas, and outflow areas are
indicated on FIGURES I and 2. T\e nearest receiving water that may receive storm water flows
from the facility is the Colorado River (FIGURE l). However, once site development begins
holding ponds are expected to contain all storm water on site.
The following is a list of specific information included on the Site Map(s):
/ Site boundary
/ Access & haul roads
,/ Stormwater outfalls and an outline of each drainage area for each outfall
,/ An estimate of the direction of flow

Good HousekeePing
Good housekeeping practices at the site are designed to maintain a clean and orderly work
environment. This is accomplished through proper operation and maintenance of machinery and
processing equipment. careful material storage practices have been implemented. House
keeping includes prevention and/or reduction of spilled aggregate and other particulate material.
Principal good housekeeping procedures ile as follows:
o The material inventory is kept up to date, and all containers are labeled with the
name and associated hazards.
Material safety data sheets (MSDS) are available on site to ensure that operation
staffis aware of hazards and pollution potential.
Routine cleanup operations are ongoing and scheduled to ensure that the storage
areas and maintenance areas are clean and orderly.
Good housekeeping, including cleanup procedures and disposal requirements, are
incorporated into anployee training.
Solid waste receptacles are available on site and are emptied regularly.

Spill Prevention and Response Procedures
The facility contains sufficient amounts of stored petroleum products as to require the
development of a formal Spill Prevention, Control, and Countermeasure (SPCC) Plan, a copy of
which is kept on site. Training and procedures established under SPCC rules are applied to all
petroleum storage within Larfarge facilities. Secondary containment is provided for the diesel
fuel and oil storage tanks should releases occur. Removal of accumulated liquids from the
containments is accomplished by use of absorbents, portable PumP, or other technique, and waste
material is proPerlY disPosed of.

aggregateand concrete, and small amounts of cleaning liquids that have no identified impairment
of surface or ground water.
Employee Training
Training of personnel is conducted annually to educate employees, at all levels of responsibility,
about the components and objectives of the storm water management plan for the site.
The training scope will include the following topics:
Spill Prevention
Spill Response
Good HousekeePing Techniques
Materials Management
Sediment & Erosion Prevention
Definition of Process Water
Best Managernent Practices in Place and Proper Maintenance
While operations are conducted on site, it will be the responsibility of the site manager or
operator in charge to train appropriate on-site personnel so that the goals of the SWMP are
achieved.
Various other tlpes of environmental training are conducted at different levels of the site
management. Environmental Training topics are produced for 'tailgate' meetings to discuss site-
specific environmental management. Site managers participate in a number of internal and
industry management meetings where environmental pollution control, regulations, ffid
responsibilities are discussed.
Records of personnel training conducted, including personnel in attendance, date of training, and
scope of training are available through the facility manager'
Identification of Discharge other than Stormwater
The site has been evaluated for the presence of non-stormwater discharges. Water associated
with portable wash plants for processing aggregate, mine dewatering as necessary, and water

used in the production of concrete are the primary sources of non-stormwater on site' Mine
dewatering is monitored as outlined above to ensure no compliance with our permit restrictions'
All other sources are contained within the site and are not discharged with stormwater' Water
stored and applied on site for dust abatement is periodically utilized on the yard site and the
access roads to suppress fugitive dust. Applied dust control is not applied in excess amounts that
would result in an off-site discharge of liquids. Dust abatement is not necessary during
precipitation events; therefore, no non-storm water at the site is intermingled with storm water
runoff. Water and other liquids utilized in other peripheral uses and in the production of
aggregateare contained within the plant. Any mechanical failure with the potential to allow a
surfaces release would be addressed through the site's spill response or emergency response
protocols, free liquids would be isolated and adsorbed, and adsorbents properly disposed'
Currently, no stormwater or commingled process water are in sufficient quantities to discharge
from the site. Should subsequent water uses be initiated on site, these water sources will be
identified in the table below:

SECTION 4
Comprehensive InsPections
Comprehensive inspections performed by qualified individuals, record keeping and intemal
reporting are essential activities under the SWMP and are outlined below. All records and
reports are to be maintained with the plan at the managing office.
eualified personnel shall make a comprehensive inspection of the stormwater management
system at least twice per year in the spring and fall for all active facilities. For idle sites where
an employee is not stationed or does not routinely visit the site, inspections shall be conducted
every two years. For inactive sites, inspections shall be conducted every three years. These
comprehensive inspections must be documented and summarized in the Annual Report.
Material handling areas, disturbed areas, areas used for material storage that are exposed to
precipitation, and other potential sources of pollution identified in the SWMP in accordance with
the permit shall be inspected for evidence of, or the potential for, pollutants entering the drainage
system. Structural stormwater management measures, sediment and conhol measures, and other
structural pollution prevention measures identified in the plan shall be observed to ensure that
they are operating correctly. A visual inspection of equipment needed to implement the plan,
such as spill response equipment, shall be made.
Based on the results of the inspection, the description of potential pollutant sources and pollution
prevention measures identified in the plan shall be revised as appropriate. Such revisions shall
provide for implementation of any changes to the plan in a timely manner, but in no case more
than 90 days after the insPection.
A report summarizing the scope of the inspection, personnel making the inspection, the date(s) of
the inspection, major observations relating to the implementation of the SWMP, and actions
taken as described above shall be made and retained as part of the SWMP for at least three years.
The report shall be signed by a Lafarge employee authorized to certiff the plan.
