GOLDEN.COLO 8040 1 279- 6 611

Asphalt Paving Co. of Golden, Colorado proposes t he development of a limited impact gravel mining operation on 9. 69 acres of land located approximately one-half mile southeast of Sil t , Col orado. This proposed plan entails enlarging the size of the existing pond in order to obtain the gravel resources while still ~a j..ntaining the general character of the site and the neighborhood. s halt Paving o. intends for this operation o e use only on a job-to- .

.,j_ob basi~ for jobs that they may procure in the area. Therefore, a portabTe asphalt plant and/or a portable concrete plant may be located on the s ite from time to time.

As phal t Pavi ng Co. purchased t hi s land in 1981 and feels tha t the best use for it is a small scale gravel operation tha t will con­tribute to a developing Garfield County.

This application is being submitted to the Garfield County Commissioners in order to obtain a conditional use permit for the proposed operation. In conformance with all appli cable rules and regula t ions , background informa t ion on t he site and the nature of the proposed operation is presen t ed in t he followi ng appli cation.

This application has been prepared by:

MINING PLAN

The land owned by Asphalt Paving Co. consists of two islands of alluvial

material located between branches of the Colorado River approximately

one-half mile south of the town of Silt, Colorado (Section 10, Township

6 So uth, Range 92 West, 6th P.M., Garfield County, Colorado). The

proposed site includes approximately ~12 acres of which only 9. 69

acres will be mined.

Before mining begins, the overburden and topsoil will be stockpiled

al ong the west edge of t he pit to provide more barr ier between our

activity and the agricultura l activity and wildlife in the area .

Also, before mining begins, effluent water

~ua li ty will be construc t ed at t he nor t hwestern corner of the pro per ty .

A pump will be installed to discharge water into t he Colorado River

from the western side of the sediment pond. This site will be dewatered

during the life of the project. a NPDES permit ha s been obtained for

t hi s site (Permit No. C0 -0038962) .

This site will be mined for sand , gravel and aggregate products ex tending

over a five ye"&.r period. Mining will start at the western edge of the

indicated mining area as shown on mining plan map (Exhibit A). A dragline

<

Exhibit la, pg. 2

or large bac khoe will be used to excavate t he material and stockpile it

at a point also wi t hin the 9.69 acres. Portable crushers, a portable

be set up as needed

within t he boundaries of t he indicated 9.69 acr es

The intermittent stream whi ch flows from east to west across t he property

will continue to run and irr igate t he property as it will co ntinue to be

used for agricultural purposes.

It is Asphalt Paving Co. 's intention

undist urbed setbacks from t he river Therefore, a Corps of Engineers

404 permit will no t be required . However , t h~y will be not ifi ed of ou r

in tent ions .

This mining plan was designed with the purpose of disturbing as little of

the ex i st ing neighborhood and env ironment as poss ibl e.

It is and will remain a primary objective of Asphalt Paving Co. to keep

their operations as aesthetically appealing as possi ble.

It should be re-emphasized at t hi s po int t hat As phalt Paving Co. intend s

to use t hi s operation only on a job-to-job basis fo r jobs t hat t hey may

procure in the area.

EXHIBIT lb

5.03.07 RECLAMATION PLAN

After mining is completed, a combination of scrapers, frontend loaders,

motor graders, and/or a dragline will be used to redistribute the

stockpiled overburden and topsoil around the shores of the lake. Where

feasible, aesthetically attractive undulations in the shoreline of the

lake will be created with reject material and surplus overburden to

enhance its appearance and increase the suitability of the site for

wildlife habitat. Shoreline banks will be constructed to be a minimum

slope of 3:1 to ten feet below water level and 2:1 from that point to

the bottom of the lake. Topsoil will be distributed over the lakeshores

to a depth of 6-12".

fhe postmining reclamation of this land will create an aesthetically

attractive lake between two branches of fast flowing river water; this

will create an area of stillwater wildlife habitat where none existed

previously in this stretch of the river (See Exhibit B; Map Pocket 2).

Surrounding land uses are similar to the proposed postmining land use

in that large areas of undeveloped land exist along surrounding river

banks, and commercial, industrial or residential development is extremely

limited in the areas immediately surrounding the site. In addition, the

major portion of the land wil 1 stil 1 be agrarian in nature.

Grading

Following mining, overburden and reject material will be used to re­

establish slopes around the perimeter of the site which will be 3:1 from

Exhibit lb, pg. 2

ground level to 10 feet below water level, and 2:1 from that

point to the bottom of the lake, except in areas where available

material is used to modify the shores for wildlife habitat, in

cooperation with the Colorado Divi sion of Wildlife. For instance,

if enough insufficient material exists after completion, a 70-90

foot mudflat will be constructed .

Backfilling and slope stabiliza tion will be conducted sequentially

as mining is completed. No probl ems with erosion are anti ci pa ted

due to the moderate angle of the proposed slopes.

toxic mater ial s are be i ng mined on the s i te , or wil l be created ---by processing activities on the site . There will be no open

exploratory holes or mine shafts created by this mining operation .

5. 03 .07 la Water

The operator does not anti cipate that any of the proposed mining

or rec lamati on activities will cause any di stur bance to t he pre­

vailing hydrolog ic ba lance . Further information i s inc luded in

Ex hibit le, Water.

All appli cabl e Federal and State wa ter l aws will be complied wi t h.

The operator has been issued a Na tiona l Poll utant Di scharge

El iminat ion System (NPD ES ) permi t.

Exhibit l b, p..9..:_]_

5.03.07 l e WILDLIFE

Although this general area of the Colorado River has been

designated as potentially important habitat for great blue

herons, bald eagles and waterfowl, the operator has designed

the mining plan so that it will have little or no affect at

all upon them.

Although the lardowned by Asphalt Paving Co. is not part of the

great blue heron rookery, some of the large cottonwood trees and

some of the marshy riparian habitat on the site are used by the

herons as a feeding and roosting area. Under the proposed mining

plan, none of the r i parian habitat will be affected and it is ' ant ic ipated t hat all of the co ttonwood trees presen t on the s i t e

will remain. Additionally, the plan was intentionally designed

to stay away from the west edge of the island to afford a maximum

distance between any mining or production activity and the great

blue heron rookery.

Finally, it will be the operator's intent to create a 70-90 foot

mudflat providing enough insufficient material exists at reclamation

time.

The reclamation plan as proposed will provide a previously non-

existent stillwater wildlife habitat surrounded by the already

existing Colorado River riparian and free-flowing river habi tat ,

and will not endanger any potentially criti cal habi tat .

Exhibit lb, pg. 4

Revegetation

Topsoil will be replaced on the site following mining using scrapers

and/or other earth n~ving equipment . The so il will be disced and drill­

seeded with the fo llowing seed mi xture:

Species

Streambank wheatgrass

Intermedi ate wheatgrass

Western wheatgrass

Russian wildrye

Yellow sweetclover

Cottonwood trees already existing on the periphery of the site will be

left in place and will be integrated into the final reclamation plan.

Natural vegetation such as sa ltgrass and willows will be allowed to invade

the site after recontouring and reseeding is completed.

Reclamation will occur so that it is completed wi thin approximately 12

mont hs of t he cessat ion of mining.

5.03.07 WATER (la )

EXHIBIT le

The configuration of the proposed mining area is shown on the maps

accompanying this application. The pit area created by mining will be

dewatered while t he operation is in progress . Water will be pumped

into the Colorado River from the west side of the pit. An NPDES permit

has been issued to allow t he operator to discharge into the Colorado

River.

No stockpiles will be placed in such a position that t hey mi ght cause

pollution to surface or ground water during or after the mining operation.

Ap prox ima te ly 5,000 ga l lons of water per day of operation will be required

for dust suppression in t he mining area and on the access roads.

·-., Water will be obtained through rights owned in the Burnett Ditch.

Also, all intensive activities (i.e., asphalt plant, concrete plant, etc.)

will be placed at elevations above the 100 year flood elevation of 5,426 .

RE: Specia l Use Permit app li cation by Asphal t Paving Company to operate a sand and gravel mine south of Sil t.

Dear Ms. Houben:

February 6, 1984

Referen ce i s made to Michael Grode's l etter to Garfi eld County dated January 14, 1982 (copy encl osed ). As t he Col orado Divi sion of Wildlife stated in that l etter, the Col orado River cor ridor near Silt is an important wildlife area. In the i m­mediate vicinity of the project area i s the l argest known grea t blue heron rookery on the Colorado River in Colorado, a bald eagle communal r oost si t e, numerous bald eagl e hun ting perches, and i s l ands used by Canada geese for nesting and brood rearing. A map showi ng the l ocation of t he rookery, a communal roost s ite, and hunting perches i s attached to the January 14, 1982 l etter.

We fee l the proposed project will cause disturbances to wildljfe. It i s difficult to predict the magnitude of t hese di sturbances because of t he project' s prox imity to sensitive wildlife resources. The reduced scal e of t hi s proposal, ver sus t he proponent' s 1982 plan, will result in disturbances of shorter durat ion and destruc­tion of l ess wildlife hab i tats . As such, the l atest plan i s preferabl e . We are concerned, however, for the cumulative impacts of subj ect proposal along with other operating gravel operations and permitted but as yet undeve loped operations i n the area . (Note there are a number of pits permitted but not operati ng i n Garfield County at present). The cumul ative resul t is a gradual dwindling of wildlife hab­itats and increase in di sturbances along the Col orado River riparian corridor i n Garfi eld Co unty . Thi s r epresent s probab ly the most s igni ficant ad verse imp act to wildlife al ong t he river. At what point enough development i s enough for wil dli fe , we cannot say at this time. However, oftentimes a s ignifi cant adverse impact only becomes apparent once it has occurred. Then it may be too l ate to recti fy t he damage. As a prerequi s ite for t he County ' s permit, we recommend t hat a need for th i s project at th i s time be establi shed. This could prevent unnecessary di stur ­bances t o wi ldli fe.

We are al so concerned that the subj ect proposal i s just a part of a pi ecemeal pl an that would eventually res ult in a project similar to the 1982 plan. The propon­ent s make no ass urances that this i s not their intenti on. We di d f eel the 1982

plan would adversely effect wildlife and recommended project modifications. These recommendations, again, are:

(1) Phase IV and V should not be mined. Both areas are composed primarily of wetlands containing vegetation that provides important water quality functions, acts as a vegetative screen, and encompasses essential wildlife habitat, es­pecially for bald eagles, great blue herons, and Canadian geese. Mining in these two areas would not only remove this vegetation and its function; but could disrupt great blue heron nesting as well as bald eagle use of the area. If phase IV and V are not mined they will retain normal riparian functions and serve to buffer mining disturbance on the large island from the herons and eag 1 es. (Phases IV and V were 1 ocated approximately west of the orange 1 i ne on the attached 1982 map. No mining should occur to the west of this line).

(2) A 100' greenbelt should be left between the pit and the river and along both the north and south wetland channel.

(3) The sediment pond should be located to the south of the north overflow channel so that it can discharge into the channel rather than directly into the river.

(4) The pit shoreline and bottom should be irregular to enhance aquatic life forms. Peninsulas are desirable since they create additional edge.

(5) Several islands with natural vegetation should be left to provide nesting areasfor waterfowl and passerine birds.

(6) Cottonwood trees the greenbe 1t). basis.

should be retained around the perimeter of the pit (i.e. Any cottonwood trees removed should be replaced on a l :1

(7) An area sloped at 5:1 and 150' in length should be left along the south­western corner to create a mudflat for waterfowl and encourage growth of aquatic emergents.

(8) Areas of intensive activity such as crusher, batch plant, etc., should be located away from the river, -]tt'eferab·ly near the road ...

(9) No activity should occur on the western end of the island from March l to May 15 to prevent disruption of great blue heron nesting. (The need for this recommendation should be evaluated prior to any expansion of the subject proposal).

(10) Disturbed areas should be revegetated with native shrubs and grasses.

If a Special Use Permit is granted for the subject proposal, above recommendations 4, 8, and 10 should be made conditions of that permit. Jn addition, we recommend that once this mining operation is completed, all related facilities; i.e. crusher, asphalt plant, concrete plant, etc. be removed from the island. Otherwise, operation of these facilities could continue with materials brought in from else­where. Removal of the facilities would eliminate some of the disturbances to

RE: Special Use Permit - Asphalt Paving Canpany Gravel Pit

Dear Terry:

The Division of Wildlife has revi~ Asphalt Paving Canpany's proposed gravel operation near Silt, Colorado, and =uld offer the following ccmrents.

The proposed operation is located in an extremely sensitive wildlife area and as such will require m:::dification of the proposed mining plan in order to reduce adverse impacts to resident wildlife populations. The Colorado River ==idor near Silt is an extrerrely :irnp::irtant wintering area for the endangered l:ald eagle. The eagles utilize the channels near the proposed operation as well as the islands themselves as hunting areas. The large =ttonw:xrl trees located on the islands serve as hunting perches and r=st sites for the eagles. I have enclosed a map depicting bald eagle observations recorded over the past three winters by Division of Wildlife and Bureau of Land Managerrent personnel. As evidenced by the preponderance cf hunting perches and the crnmuna1 r=st site, this area is heavily used by the balG. eagle. This -o:::mnunal r=st site is one of only four known roost sites on the Colorado River. A =mrunal r=st site is where the eagles tend to =ngregate for the night and is generally indicative of a high eagle use area.

Intensive activity, such as a gravel operation, within a high eagle use area, oould place additional stress on the eagles, or cause abandonment of this area by the eagles to an area of less suitable habitat. The Silt area represents an area of optimum hab­itat selected by theeagles over the years because of the available perch and r=st trees, and the abundant fcioa. source. Research studies have shOwn t.'iat eagles wintering in suboptimal habitat are subject to nnre stress and have lower reproductive success than eagles wintering in optinrum habitat. Since it is the intent of the Endangered Species Act and the Bald Eagle Protection -Act to prevent further decimination of the l:ald eagle population it v.uuld seem imperative that activities potentially harmful to the eagles be nndified to prevent any adverse impacts.

In addition to the perch sites and =mrunal roost site, the largest known great blue heron rookery on the Colorado River is_found on the island adjacent to the proposed gravel operation (note map). The herons are very sensitive to disturrence especially during the nesting season frc:m April l to May 15. The wetlands and shallO\-l areas of the river channels represent an irrp:lrtant food source area for the herons. Precautions

should b2 taken to prevent any distrutance to the herons during the nesting period and to preserve the integrity of the wetlands and water channels.

Another irnp::>rtant wildlife specie that will b2 :imp3.cted by the prOJ_::osed gravel operation is the canadian goose. The islands, including the island where the main operation is planned, are used as nesting and brood rearing areas by the geese. The cx:rnplex of channels and islands provide excellent habitat for rearing the young geese and attract a large concentration of geese into the area fran March 1 through May 30. ~bst of the nest sites are located on the upper pation of the wetland areas designated on the rrap.

The riparian zone which includes J:oth the wetland and upland areas adjacent to the river represents only tw:> percent of the total land mass in Colorado yet is used by 90 percent of all wildlife during sare part of their life cycle. In addition to providing iJn!::ortant wildlife habitat, the wetland co=idor serves to provide :inp::>rtant water quality functions by acting as a natural filter and flccd control rrechanism. Another irnp::>rtant function provided by the wetland/cottonv.uod area (i.e. phase IV and V mining area) , is that it protects adjacent areas fran mining activities by serving as a natural vegetative screen and buffer. Since the heron rookery, bald eagle perch sites, and roost site is located irrrrediately adjacent to this operation this is an extrEm2ly iJn!::ortant function.

Having evaluated the proposed gravel operation it is apparent that if nuru.ng is to oc= at this site the existing mining plan will have to b2 rrodified .to reduce potential adverse :imp3.cts to resident wildlife populations. I WJuld re=rrend that the following l:e rrade conditions of the special use pennit in order to protect existing vegetation, water quality, and wildlife:

(1) Phase IV and V should not b2 mined. Both areas are a:mposed primarily of wet­lands containing vegetation that provides iJn!::ortant water quality functions, acts as a vegetative screen, and enccrnpasses essential wildlife habitat, especially' for bald eagles, great blue herons, and Canadian geese. Mining in these ti-D areas WJuld not only rerrove this vegetation and its functions rut could disrupt great blue heron nesting as well as bald eagle use of the area. If phase IV and V are not mined they will retain norrral riparian functions and serve to buffer mining disturbance on the large island fran the herons and eagles.

With respect to information presented on the pre-mining rrap, the wetlands adjacent to the north channel of .the large island are not shown. The wet­land area on the southern area is shown but the channel which traverses the wetland is not sh::Twn (please note enclosed map~. A 404 permit is needed to =rk in J:oth areas.

(2) A 100' greenbelt should be left between the pit and the river and along J::oth the north and south wetland channel.

(3) The sed:irrent pond should be located to the scuth of the north overflow channel so that it can discharge into the channel rather than directly into the river.

(4) The pit shoreline and l:ottan should be irregular to enhance aquatic life foI111S. Peninsulas are desirable since they =eate additional edge.

(5) Several islands with natural vegetation should be left to provide nesting areas for waterfowl and passerine birds.

3f

(6) Cottom-.D<Xl trees show.ct re retained around the perim..._2r of the pit (i.e. the greenbelt). Any rottonv.ocd trees rerroved should re replaced on a 1:1 basis.

(7) An area sloped at 5:1 and 150' in length should re left along the south­~stern rorner to =eate a mudflat for waterfowl and enrourage growth of aquatic errergents.

(8) Areas of intensive activity such as a crusher, batch plant, etc., should re located away fran the river, preferably near the road.

(9) No activity should oc= on the ~stern end of the island fran March 1 to May 15 to prevent disruption of great blue heron nesting.

(10) Disturbed areas should re revegetated with native shrubs and grasses.

It is my opinion that if these recxxrrrendations are :implerrented impacts to wildlife and this riverine e=systan can re minimized. I would re-anphasize the imp:>rtance of not mining phase IV and V J:;ecause of the =itical habitat rontained in these tracts and because of the potential impacts to wildlife, particularly the bald eagle and great blue heron.·

The Division of Wildlife appreciates the opportunity to carrnent on this project.

Silt, Colorado 81652

Feb. 6, 1984

·11JWN ot.~11 -. . P.O. Box 174 Silt, Colorado 81652 303 876-2353

General Comments:

Area is located within 1/4 mile of Silt Town Limits

within the area designated in the Silt Town Comprehensive

Plan as B7. B7 is designated as a Secondary Growth Area,

an area for rural subdivision density. Area immediately

north of the River is designated as medium density residential.

As such, a gravel pit and asphalt batch plant are clearly

imcompatable uses with the designated Town uses. The Silt Comprehensive Plan requests that any development

must make provision for the dedication of riverfront trails

for wildlife observation. Access is requested.

Specific Comments: 1. With the undeveloped Corn Pit and the marginal economic

operation of the existing pits in the immediate area, a need

has not been demonstrated for the proposed.

2. The immediate experience with the temporary batch plant

at the Frei pit clearly demonstrates retainage of s~oke and

smell to be severely offensive in smell and sight. 3. The Town of Silt Water supply is located in an underground

acquifer. Past experience with excavation in the area of

the Silt bridge indicate that dewatering poses an i~minent

threat to both quality and quantity of the Towns only water supply. Engineering studies indicate impact mitigation

could run as high as $850,000,00 to the Town. All exhibits

completely ignore the impact upon the Towns Water supply.

Further mitigation measures must address the possibility of contamination of the underground sources by diesel fuel

or other organic ccntaminents.

4. This application if approved clearly sets a precedent

for the other 103+- acres for gravel mining.

1 U VY 1 V 01 ;:::,-Jl P.O. Box 174 Silt, Colorado 81652 303 876-2353

5. Upon approval of the Corn Fit, a condition was that a

traffic study be done to determine mitigative measures dealing

with traffic flows on the Silt Exit. This study has not been

done. The estimates of traffic of the Asphalt seem low. The. potential for traffic problems with buildout of existing develop

ment and gravelpit traffic is of concern. The Town of Silts

economic future depends on its viability of access. A mitigative

measure might be to send all traffic south and west to the new

Mamm Creek Interchange.

6. There is no timetable for completion of the reclamation

plan. Conceivably the pit could be unreclairned for 20years.

7. All outdoor storage of any items such as barrels,timbers,

tanks, or sheds must be above the 100 yr. flood elevation.

8. This is substan)!:ially the same proposal as submitted previously to the County and Silt. The Town of Silt based

on several grave concerns reccomends_denial.

9. Please note the concerns of the Dept. of Wildlife.

Dear Mark:

Silt, Color. I 81652 303 876-2353

May l 0, 1983

Historically, Silt has opposed the majority of industrial uses outside its corporate limits yet within its area of influence. And wishes to 90 on record as opposing this request.

The Asphalt Paving Co. was denied gravel pit operation approval by the County Conmissioners in May of 1982. Silt officials are hoping all pursuant will be consistent.

If my chronology is correct, prior to A.P.C. 's request denial, Corn Construction was granted approval for a gravel pit. They also signed an agreement with the Town of Silt (see enclosed letter) which neither they nor Frei and Son's have honored to this date.

The Town's water plant operator has serious concerns about the effect of on site pollution run off into the river, such as petroleum or gas production, as a result of surrrner rains.

Further, c:itizees of Silt aad aetgbbort.ng cOOlfllni ttes were appalled at the lack of pollution monitoring the Frei operation received during its; 30-day permit last surrrner. Obnoxious black smoke belched daily during plant operations.

Once again Silt appreciates the opportunity to provide input •

Re: Asphalt Paving Permit-Weld County

Dear Cindy:

Thomas M. Vernon, M.D. Acting Executive Director

Attached is a copy of the Emission Permit issued to Asphalt Paving Company for a Stansteel Model 8 X 36 drum mix asphalt plant. This plant is required to meet the New Source Performance Standards (NSPS) enforced by both the State of Colorado and the U.S. Environmental Protection Agency for new asphalt plants. Due to the high efficiency required to meet these standards, adverse impacts on ambient air quality are expected to be minimal as noted in the accompanying project summary.

All other air pollution sources noted in the special use application have not been applied for or have been granted Emission Permits from the Colorado Department of Health, Air Pollution Control Division. Until these permits are issued, total air quality impacts for this proposal cannot be determined.

Of further concern to the Air Pollution Control Divisiin is the cumulative effect of all the gravel pits locating in the same area. Again, this cannot be addressed by the Division until a permit application has been filed.

Thank you for the opportunity to comment on this project.

Dear Sirsa

In sprin!; of 1982, the :}arfield County Commissioners refused to issue a special use pennit for a gravel operation o:i property owned by Asphalt PavirL'; Go. 'L'i1e main reasons for denial werea

1. Cumulative impact 2. Incompatabili ty with nei:{hbors J. Opposition from Town fo Silt and residentsot county

The Division of Wildlife was also concerned as to the effect of a gravel operation on the large Jlue ieron and Eagle populations. As ·it now stands all the reasons ';iven for denial are still the sarne.

There still are too many gravel pits in a small area, the neighborhood is still rural-agricultural in nature, a pit in this area is contradictory to the Silt Comprehensive Plan, and ~lso the Llou11ty ?lan. ·;<he 'l'own of Silt is also concert.ed 3·oout the eff'ect oi' a :;ravel operation so close to tneir Y\ew w3ter filtration plant.

In 1982 we J1elped circulate a petition to show the commissioners a broad public opposition to d !;ravel pit at this location. As I see lt that petition is just as valid for this special use permit as it was in 1982. there is still a great deal of opposition to a pit so close to town and so close to other operations. Where do we draw the line? I thought we drew it in 1982.

Garfiel .. d County Plan· ~---·

Asphalt Paving Comp. February 8, 1984

,ng and Zoning Col'lmission Application for Gravel ~ .~, etc.

The Garfield County Citizens Association, a group of more than

70 residents throughout the County, appreciates this opportunity to

comment on Asphalt Paving Company's application for a special use

permit to operate a gravel mine, asphalt batch plant, crushers and

concrete batch plant. In the Spring of 1982, the Citizens Association

took a position opposing a gravel operation in this location. We see

no reason today to change that position. Once again, we ask that the

Planning and zoning Commission recor.c~end den~al of this application.

The Citizens Association supports the recommendation for denial

of the Garfield County Planning Staff. We concur with the Planning

Staff that (quote) ''there is no evidence that there has been a

change in the character of the neighborhood." (end quote)

In their resolution of May 24, 1982, the Garfield County Commissioners

found that (quote) ''the general character of the neighborhood .. ,is

agricultural/residential". (end quote) That pattern of land use

has not changed. The applicant again is proposing an industrial use

that is incompatible with the character of the agricultural and residential

neighborhood--a use which could very well injure the heal th, safety

and well-being of nearby residents and a use which would necessarily

decrease their property values.

The Citizens Association also concurs with the Planning Staff that

(quote) "there is no evidence that the 1984 proposal now complies with

the Garfield County Comprehensive Plan." (end quote) We believe ·the

request fails to satisfy the Comprehensive Plan in the ways described

in the Planning Staff's report.

In opposing this proposal, the Citizens Association supports the

concerns of the nearby residents who submitted letters to you and the

Asphalt Paving, Feb. 8, 1984 Page two

residents who signed a petition in opposition. We believe these

residents' concerns are justified.

The Citizens Association also supports the position of the Town of

Silt. We believe the proposed operation is incompatible with Silt's

plans for future growth as designated in the Silt Comprehensive

Plan. We believe the applicant has not satisfied the Town that

there would be no harm to its water supply both in terms of quantity

and quality.

In addition, we concur with the concerns expressed in a letter to

you from William R. Elmblad with the Colorado of Wildlife.

In his letter, Mr. Elmblad stated that gravel

probably the most significant adverse impact to wildlife along the

river. 11 (end quote)He questioned, (quote) "At what point enough

development is enough for wildlife, we cannot say at this time."

(end quote) He dontinued, (quote) "However, oftentimes a significant

adverse impact only becomes apparent once it has occurred. Then it

may be too late to rectify the damage." (end quote)

We repeat his statements because we feel it is important to underscore

them in your minds. The potential harm to wildlife as a consequence

of the proposed gravel mine is unpredictable--even to experts.

In early 1982, the Citizens Association questioned the need for more

gravel operations in Garfield County. We feel the same today as we did

then. The applicant has not demonstrated that a need exists for this

resource at this time. In conjunction with this new application,

nearby residents, the Town of Silt and the Division of Wildlife all

question1thetnee for another gravel mine. Mr. Elmblad wrote in quo e1

his letter, "As a prerequisite for the County's permit, we recommend

that a need for this project at this time be established. This could

prevent unnecessary disturbance to wildlife.'' (end quote)

In their 1982 resolution for denial, The County Commissioners

Asphalt Paving, Fe• Page three

8, 1984

addressed the question of need. They found that (quote) ''deposits

of commercial grade gravel are of importance to the general welfare

of Garfield County and that there is a need to conserve valuable

resources for future generations." (end quote) The Commissioners

concluded, (quote) "To the extent that the County has recently

permitted a number of other pits in the general area so that commercial

grade gravel is presently available, it is appropriate to deny the

applicant's application ." (end quote)

Other pits in the Silt area today are not producing at anywhere

near their capability. We believe that this is ample proof that

there is no demand for still another pit. Once more, the circumstances

have not changed since 1982--if anything, there is less demand today.

Along with nearby residents, the Town of Silt and the Division of

Wildlife, we are also concerned that approval of the nine acre pit

will open the door to further requests for expanding the operation.

That only makes sense. A nine acre pit will not recover the purchase

price of the property for the applicant.

There have been rumors that if the application is denied, the

applicant will again attempt to sue the County. In our minds, -

the County is more at risk in court if it should grant this permit

and then deny future requests for expansion.

We feel that the applicant made an honest mistake in purchasing

property that is zoned agricultural/residential/rural density. We

understand the applicant's continuing financial dilemma. But we

don't believe that the residents of Garfield County should be made to

pay for the applicant's mistake. In our minds , the applicant has

not demonstrated that there would be enough benefits from the proposed

gravel operation be tlte resiilelil" of Garfillloil CQYRiry° to counterbalance

the much more clear harm that it would bring to nearby landowners,

the Town of Silt, wildlife and County residents in general.

Dear Sirs,

Once again the Garfield County 1' : !, and the Commissioners must make a decision concerning gravel operations on the Colorado River in Silt. This is a request for a special use permit to mine gravel by Asphalt Paving Co who tried to obtain a permit two years ago and failed, The County Comr:iissioners denied the perni t for these reasons, among others:

1. Cumulative impact to area(created by noise,dust,traffic,etc) 2. Incompatability with area v1:iich 'Jtill rem8iX:fJ basically

rural and agricultural J, Opposition from the 'l'own of .Silt because of the effect

on their water intake system 4. Opposition from residents(petition submitted carrying

800 names) 5. Opposition f:f'orn v1ildlife officials

I have all the sarne concerns as two years age, the situation on the river has not changed and the reasons listed above for clenial still apply.

'I'he request this time from Asphalt Paving is for a much smaller area to be mined, but my concern is: if once the area is changed in use to allow for this small pit, what will be the si1buation when Ashal t Paving applys to expand (as did l''rei ,'" Sons)? The Commissioners fel), in the Prei & Sons case, that they had no good reason to deny them their expansion permit because the area was already in use by gravel operations. This could very well be Asphalt Paving's plan.

And now we ,re back to the orL!i,1cil question we posed two years ago of need, and of impact? Yet since then, irei is now in full operation and have expanded greatly, only making need less of an issue.

We don't r•eed any more gravel and related operations on the Colorado River. Please deny Asphalt Pavin:?;s request for a special use permit.

As Larry Velasque stated at the .. 1ay 12, 1982 meeting to deny Asphalt Pavings first request- he said he might in the future be less inclined to approve such permits, even if a need for gravel was demonstrated. ''We have a responsibility to future generations to disallow anyone to come into the county and exhaust our resources," It could be, he said, that developers may have ''to import some of the materials from other areas,''

I appreciate you taking into concideration my thoughts when you· make your decision.

RE: Water Resource Investigation, Silt Pit

Dear Jeff,

The following report outlines our study results and conclusions concerning the impact of Asphalt Paving's proposed gravel pit on the Town of Silt's municipal water supply system. In summary, we have concluded that your operation will not have a measurable impact on the quantity and quality of the towns water supply. We base these conclusions on the following observations:

1) Dewatering a one acre open pit will initially require a pumping rate of 2.2 cubic feet per second (cfs) to lower the water table to the desired elevation. A continuous pumping rate thereafter of 1.5 cfs will sustain the low water table elevation. Upon full development a seven to eight acre open pit could require a continous pumping rate of 4.2 cfs.

2) The underlying aquifer and nearby Colorado River are hydraulically connected. Approximately 95% of the sustained pumping rate will originate directly from the river.

3) A 1.4 cfs to 4.2 cfs direct depletion of Colorado River flows during the critical winter low flow season will not have a measurable impact on stream levels. Approximately 60 cfs would have to be pumped from the river to lower the stream elevation one inch.

4) Aquifer pumping and sediment pond overflow will be discharged into the Colorado River on the west end of the site, downstream of the Town's water supply system.

5) Asphalt Paving will develop and implement a Spill Prevention and Containment Plan as required by the State.

6) All potential toxic materials, including diesel fuel and gasoline can be stored at an elevation above the 100-year flood plain.

INTRODUCTION

Purpose

The purpose of this study is to determine what impact the

development and operation of the proposed Asphalt Paving gravel

pit will have on the quantity and quality of the Town of Silt's

municipal water supply.

Backaround

The proposed Asphalt Paving gravel mine is located on an

island of the Colorado River, immediately south of Silt, Colorado

(Figure 1). The island is an alluvial formation consisting of a

mixture of sands, gravel and cobbles that have been deposited by

the Colorado River. The permeable nature of this material and

proximity of the site to the river, create a perennial high water

table underlying the property. As a result, the open pit will

require dewatering during operation to facilitate efficient

extraction of the mined material.

The Town of Silt is concerned that pumping the aquifer could

have an adverse impact on their nearby municipal water supply

,system. Their system consists of an underground infiltration

gallery adjacent the Colorado River approximately 1 ,750 feet

northwest of the proposed gravel pit. The proposed pit and water

system are separated by a main branch of the Colorado River.

The Town fears that significant pumping could lower the water

table elevation of the Town's water system, thereby lowering its

yield and perhaps adversely affecting its quality.

WATER QUANTITY

Rate of Pumping

In order to assess the impact of prolonged pumping on the

surrounding aquifer, we first had to define t~.e rate of pumping

necessary to sustain the desired lower water table elevations.

We were able to calculate this value using existing information

that included; previous reports, Asphalt Paving's proposed mining

plan, core drilling information at the adjacent Silt bridge, and

historic dewatering observations at the nearby Frei and Sons,

Inc. gravel pit.

Core borings completed for the adjacent Silt bridge indicates

that the aquifer consists of a mixture of sands, gravels and

cobbles to a depth of approximately 20 to 25 feet. This material

is underlain by a rather impervious layer of claystone. Water

table elevations were encountered near an elevation of 5412.

The Asphalt Paving mine plan indicates that gravel removal

will extend to a maximum depth of 30 feet, or about elevation

5395. This means that approximately 17 feet (5412 - 5395) of

standing water will be encountered and must be dewatered during

periods of operation. These are nearly identical to the

conditions encountered at the nearby Frei a::iC: Sons, Inc. gravel

pit.

of 30

The Frei pit consists of a one acre ope::i pit with a depth

feet. Conversations with the plant r;-,e.Da=;er revealed that

they are able to dewater their pit with consta~t pumping from one

4 inch, 20 horsepower pump with a total lift of 30 feet.

Assuming a total pipe length of 75 feet and a pump efficiency of

80%. we estimate this to be a constant discl-;arge of 1.51 cubic

feet per second (cfs) (680 gpm). (See attachcient 1.)

3

We believe that the aquifer conditions encountered at the

Frei and Sons pit are analogous to those that can be expected at

the Asphalt Paving site. An initial one acre pit will require a

pumping rate (first week) of approximately 2.2 cfs (990 gpm) to

initially lc~er the water table and a sustained pumping rate of

1.5 cfs ( 660 gpm) to maintain the level. Because of the

proximity o:C the Asphalt Paving pit to the Colorado River and the

permeable nature of the underlying aquifer, there is a strong

hydraulic continuity between the river and the aquifer. As the

pit is dewatered and expands beyond one acre in size, the

resultant cone of depression (drawdown effect) will expand along

the river until the pump receives essentially all of its water

directly from the river. At full development, a seven to eight

acre pit will increase the original boundry effect along the

river by a factor of almost three. Consequently, we estimate

that a sustained pumping rate of 4.5 cfs would be required to

maintain a low water table throughout the pit.

We have calculated the impact on the Colorado River from

dewatering the Asphalt Paving Pit using a method developed by

Glover (date unknown). The aquifer variables necessary to

utilize this methodology were determined using the core boring

data from the bridge and the pumping data from Frei and Sons pit.

(See attachr.ent 2). The Glover method indicates that 95% of the

sustained pumping rate will come directly from the Colorado

River. This means that initially 1.4 cfs of the expected 1.5 cfs

pumping rate 'dill come directly from the adjacent Colorado River.

Upon full cevelopment, 4.2 cfs of the expected 4.5 cfs would

originate from the Colorado River.

Impact on Town of Silt

A sustained withdrawal from the from the Colorado River of

1.4 cfs to 4.2 cfs, even during the winter low flow period, will

not have a measurable effect on the water elevatior, of the Town

of Silt water supply system. A flo\v duration a~lc.lysis of

Colorado River streamflows indicates that 99% of the time, flows

of the River will be greater than 1,100 cfs. floi·1ever, because

the river channel is braided in this area, not all_ of the

streamflow is contained in the channel adjacent to the proposed

pit. Hydrologic studies completed for the recent

construction show that approximately 60" (660 cfs)

streamflow will be contained in this channel.

bridge

of the

Using stream cross section data collected at the bc~dge site

during low flow periods, we were able to calc~iate the i~pact to

the river using the Mannings' streamflo·..: equation. (See

attachment 2.) The analysis shows that during the critical, low

flow period, more than 60 cfs would have to be pumped from the

river to lower the stream elevation one inch. Removing 1. 4 cfs

to 4.2 cfs will have an insignificant and unmeasurable effect on

the river. Consequently, the water elevation at the Town o.f

Silt's downstream water supply system will be unaffected by the

gravel operation. The impact described above wo~ld e~en be less

during the summer high flow period.

\·le do not anticipate an~' adverse impacts o::-;. tt-.e C!'--:3lity of

the Town of Silt's water supply due to Asp~a!t Pa~ing gravel

operations. Aquifer pumping and sediment pond ovecflow will be

carried in an existing irrigation ditch anc dische.::?ed on the

western end of the property, downstream of the Town's water

system. An established 100 foot buffer between the River and the

pit will reduce the potential of Colorado River contamination at

any point above the Town of Silt's intake. In addition, the pit

and intake are partially buffered by a large island which

minimizes mixing of surface water (Figure 1).

Groundwater contamination due to leaks or spills is unlikely

provided Asphalt Paving implement a Spill Prevention and

Containment Plan and locate there storage facilities out of the

flood plain. The spill prevention plan is required by the State

and usually requires construction of a spill containment area

around all storage facilities. Often these areas are lined with

an impervious material to prevent seepage. Gingery Associates,

Inc. (1982) have identified a potential storage area that is out

of the 1 00-year flood plain. This will eliminate the risk of

stream contamination during flood flows and further reduce any

possible danger to public health or safety.

DESIGN FLOW: Dewatering at 600 - 1200 gpm

FACILITY DESCRIPTION: The facility is a sand and gravel operation near Silt, Colorado. An asphalt plant and a concrete mixing plant are located at the east side of the property. Crushing and screening of the material will also take place at the site.

The principal products are sand, gravel, asphalt and ready - mixed concrete.

Extraction will proceed through five phases. page 15 of the permit) It is estimated that a discharge point will handle dewatering during phases. The expected life of the activity is years.

(See single a 11 l 0

This permit covers the discharge of settled pit water. No processes at the site generate wastewater.

COLORADO DEPARTMENT OF HEALTH Water Quality Control Division Rationale - Page 2 PERMIT NUMBER: co-0038962

WASTEWATER CHARACTERISTICS & TREATMENT

As previously mentioned, wastewater will consist solely of pit water. Treatment will consist of sett\ ing prior to discharge. The pond ca­pacity is 472,000 gallons, Dewatering is estimated to occur at a rate of 600 - 1200 gpm.

Discharge point 001 shall be the outfall from the dewatering pump prior to mixing with the Colorado River, Samples for compliance monitoring shall be taken at this point.

No water qua\ ity data for the effluent is available at this time since no mine water has been encountered,

EFFLUENT LIMITATIONS & BASIS OF LIMITATIONS

Flow (MGD) NA Monjtor Only2 pH (s.u.) 6.o - 9,0 SES and B~T

TSS (mg/1) 25(30 - day ave.) BEJ of BAT 4S(Daily Max.)

Oil & Grease (mg/1) 10 SES Salinity NA Monitor Only

1SES - State Effluent Standards

2BPT - Best Practicable Technology Currently Available

3BEJ of BAT - Best Engineering Judgment of Best Available Technology Economically Achievable

The facility is classified as a primary industry in the Mineral Mining and erocessing Point Source Category, Subpart C (Construction Sand & Gravel) and, as such, is subject to the Federal Effluent Guidelines for that category.

The status of the categorical guidelines at this time is that BPT has been promulgated and covers pH only: there are presently no BAT guide-1 ines published. Permits written to expire after 7-1-83 must contain 1 imitations based on BAT. Thus, best engineering judgment was used to set BAT 1 imits for TSS.

In addition to Federal Guidelines, the State Effluent Limitations (10.l .4) also apply. This affects the permit with regard to oil and grease 1 imits. The State Effluent Standard for pH is 6 - 9 which is equivalent to BPT.

Special Permit Conditions

1. SPCC Pl an-

A spill Containment & Countermeasures Control Plan is a requirement of this permit and is detailed on page 6.

2. Salinity

In comp! iance with the "Regulations for Implementation of the Colorado Salinity Standards Through the NPDES Permit Program", the Permittee shall sample for salinity in the wastewater effluent on a monthly basis until six samples have been analyzed. Thereafter, monitoring shal 1 continue on a quarterly basis. The Division will review the first six months of data and determine if a waiver of numeric limitations can be granted based on the salt-load to the river being less than one ton/day (or 350 tons/year). If a waiver is not granted, then the permittee has an additional six months to submit a report in accordance with the Salinity Regulations, addressing economic feasability of salt-removal.

3. One - Time Monitoring

In addition to the ongoing monitoring requirements on page 3, one -time monitoring for certain additional parameters is required. (See page 5).

The permit shall expire on March 31, 1987.
