One plant is located at their pit site on Broadway Avenue and the other is operating at the Central Pre-Mix Sullivan Road pit site. Inland Asphalt wnll be purchasing a new state-of-the art asphalt batch plant and plans to erect and operate it from the Sulhvan Road pit at North 2010 Sullivan Road The two existing batch plancs will be closed, dismantled, and removed from their respective sites Coacept As shown on the enclosed conceptual master plan, the new asphalt batch plant wiil be sited along Sullivan Road, north of the Central Pre-Mix operation and west of the existing berms separating the batch and the mimng operations. The northwest corner of the site will be used for employee parking, truck parking, truck dispatch, batch plant, and matenal storage for continuous asphalt production. The mining operation east of the berm will not be impacted by the location of the new asphalt production facilities At full operation of the batch plant, an additional 450 vehicles per day will enter and exit the sYte. Adding this new traffic to the existing Centcal Pre-Mix traffic, approximately 1,000 vehicular tnps per day will be generated by both operations. Access to the site will be from two locaqons off of Sullivan Road. Flora Pit Road will provide ingress for about 300 trucks per day. There will be no egress from the site via Flora Pit Road. The second locahon will be through the exisUng Centrdl Pre-Mix entrance or a new entry north of the exi.sting entry Approximately 700 vehicles per day wtll enter and exit the site via Sullivan Road. These tnps include 270 employee tnps with the remainder being concrete, asphalt, or gravel trucks. Through discussions with County Engineers, it has been identified that Sullivan Road must be widened to provide for a north bound deceleration/acceleration lane A trafftc lighted intersection will be pnovided to control ingress and egress of the site from Sullivan Road A pedestnan access stnp along Sullivan will also be provided. This pedestnan stnp may be paved or graveled and a fi~nal determination as to surfacing has not been established. New x parlang areas, entry roads, and batch plant roads will be paved to mininuze dust.~(i-site roadways where track vehicles will be moving materials are anticipated to be gravel. New parking facilities will be landscaped as required by the Zorung Code. 208 Drainage Swales vnll be provided for all paved areas of the site and the widening of Sullivan Road 1 100 ~ Au emissions will be reduced through the relocalaon of the Inland Asphalt operahon with reduction occunng by two methods; first, the closure of two existing asphalt batch plants through the replacement wifh a new sEate-of-the-art batch plant that meets smct emission standards (additional data of plant emissions will be provlded through permrmng with SCAPCA). The second way emissions will be reduced will be through the evEntual closure of the Broadway Avenue pit site The batch plant at this site will close this fall, but gravel operahons wiil continue for approximately a 2 to 3 year penod. After that time, all operations will be conducted from che Sullivan Road Pit. ~ . • ~ • Bond No. 226574 ROADWAY ZMPROVEMENT BOND KNOW ALL IKEN BY THLSE PRESENTS, that CENTItAL PRE-MIX CONCRETE C0.

EXHIBIT NO. 1 TO THE ENVIRONIVIENTAL CHECKI.IST FOR CENTRAL PRE•MIX CONCRETE CO. February 7,1992 Part A - BackgrQund II. Brief Description of Proposal: Background Inland Asphalt Company is operati.ng two asphalt batch plants within Spokane County. One plant is Iocated on Broadway Avenue, and the other is operati.ng at the Central Pre•Mix Sullivan Road pit site. Inland A►sphalt will be purchasing a new state-of-the-art asphalt batGh plant and plans to erect and operate it from the Sullivan Road pit at North 2010 Sullivan Raad. The two existing batch plants will be closed, dismantled, and removed from the respective sites. Concept The new asphalt batch plant will be sited along Sullivan Road, north of the Central Pre-Mix operation and west of the existing berms sepazating the batch and the mining operations. The northwest corner of the site will be used for employee parking, truck parking, truck dispatch, batch plant, and material storage for continuous asphalt production. The mining operation east of the berm will not be impacted by the location of the new asphalt production faGilities. At full operation of the batch plant, an additiona1450 vehicles per day will enter and exit the site. Addi.ng this new tra.fffc to the exi.sting Central Pre- Mix traffic, approximately 1,000 vehiculaz trips per day, will be generated by both operations. These trips include 270 employee trips with the remainder being concrete, asphalt, or gravel trucks. Through discussions with County Lngineers, it bas been identified that Sullivan Road must be widened to provide for a northbound deceleration/acoeleration lane. A traffic lighted intersection will be provided to control ingress and egress of the site from Sullivaun Road. A sidewalk along Sullivan will also be provided. r New pazking areas, entry roads, and batch plant roads will be paved to mi~e dust. On-site staging areas where track vehicles will be moving materials are anticipated to be gravel. New parking facilities will be landscaped by the Zoning Code. All new paved areas of the site and the widening of Sullivan Road will be provided with 208 Drainage Swales. Air emissions will be reduoed through the relocation of the Inland Asphalt operation with reduction ocayurring by two methods; first, the closure of two exi.sting asphalt batch plants through the replacement with a new state-of-the-art batch plant that meets strict emission standards. The second way emissions wwilll be reduced will be through the eventual closure of the Broadway Avenue pit site. Tbe batch plant at this site has already been remaved, but gravel operations will continue for approximately two to three years. After that time, all operations will be conducted from the Sullivan Road Pit. • ° SG000-925 AEV:O PAGE 1 MATERIAL SAFETI/ D TA SNEE1' (MSbS) SG400-125 aEV. o oa 3J20/8e CODE 06-10 GONFOAMS TO REDUIREMENT$ F 09HA STANDAAO 1910.1200 • "HAZARO COM UNICATION" ACAiphaJl Cement COPYFi1GHT KQCH MA fAt,.S COMPIINY 1988 SECTlON I-- PRODU T lDENTIFtCAT10N VENDQR'S PRODUCT NAMZ: AC Aaplult Ce n!

I am advised that the Central Pre-cnix firm has initiated a zoning request asking for the re-zoning of their property to enable tbem to institute a sand and gravel pit operation. My clients have authorized me to advise the commission that tbey bave no objection to the zone change requested by Central Pre- mix. During the past two months, I have made an investigation of the property in bebalf of my clients and we have reached the conclusion that the area in question is a likely and suitable area for manufacture, industrial, or a sand and gravel pit operation and that ft does not have good characteristics for either agri- culteral, residential, or other zoning. Tberefore, both the Ulowetz familes recommend favorable action bq the planning commission on the petition of Central Pre-Mix for a re-zoning. Yours very truly, S~A~*E & TWIGG ~RIFCElVE:Ij_i SPoKAvE couNTt ard pe ~ ~ 1959 WJS ~ ~ • ~ CENTRAL PRE-MtX/INLAND ASPHALT New Shop Drainage Report , , , Background: -J A new shop is being oonstructed south of the existing shop at the Central Pre-Mix Plant srte on Sullivan Road. Other improvements to the sde include paved parkmg for the existing and new shop facil'fies. Drainage facilities are planned to handle the first 1/2-inch of runoff, from the new paved areas, in grassed percolation swates. Drainage Calculafions: Drainage Basin A, as shown on the attached plan, is the total drainage area for these new improvments. As shown, two grassed percolation swales will be developed along the south perimeter of the site to collect, store and dispose of stormwater runoff The westerly swale will collect water from the new parkmg area and has a storage depth of 6-inches. The easterly swale coilects water from the new shop area and also has a storage depth of 6-inches. These two swales are piped together to handle the entire basm runoff. A summary of the drainage calculations are provided below. The detailed calculations are attached: Impervious area in Basin A: New Paving 60,074 S. F. Roofs (New Shop and New Additon to existing Shop) 81100 S.F. Ewsting Paving 13t750 S.F. Total Impervious Area 811924 S.F. = 1.88 AC Only the runoff from the new paving is being collected and stored in grassed swales. Collection of the roaf drainage for the new shop and addrtion to the existing shop is not required as there is no electncal or mechanical equipment on the roof and both roofs will be of a rubberized material. The existing shop roof drainage is preserrtly disposed of through a drywell. The existing paving, which drains onto the new pavement is exempt from being stored in a grass swale prior to disposal, as per discussions with County Engineering staff. As shown on the attached rational formula input form, the dramage swales are reqwred to provide a ponding volume of 2,503.3 cubic feet (C F.). The proposed swales will provide the following storage volumes: West Swale 12 x 145 x.5 = 870 C. F. East Swale (27 x 19 x.5) + (20 x 138 x.5) = 1.636.5 C F. Total Storage Volume = 2,506.5 C.F . Disposal of stonnwater nat stored in the swales will be through one Type "Bu drywell installed in the easterly swale. As shown on the attached bowstring calculation sheet, the two swales and drywell, provide the storage and disposal capacibes to handle the 10 year design fiow from storms runoff The overflow pipe, between the west and east swales, has been sized to carry 10 cubic feet per second from Subbasin A-1. The west swale wiit coliect and store 870 C.F. of runoff prior to discharging, through the overflow pipe, to the east swale. Subbasin A-1 consists of 33,825 S.F. of new paving. The minimum swale area required for Subbasin A-1 is 1,409.5 C.F. (33,825 x 04167). The remaining 539.5 C.F (1409.5 - 870) of storage is provided by the east swale. e s(,( t vAv~V ~j ~ f~E, ~~(~py~I Sr c9 ~ 13A~iN ~tCj I~l~foN Nc--*v -s~<o,' rfojez,-r 302-g-g oo lo t , GA ~.G PML P~cf~ 4° Z$ -9 2.

GENTRAL PRE-MIX/INLAND ASPHALT SULLNAN ROAD IMPROVEMENTS DRAINAGE REPORT Backaround: The expansion at the Cerrtral Pre-Mix Suilivan Road srte requires the development of a deceleration/acceleration lane on the east side of Sullivan Road This lane starts at ihe north end of the Spokane River bridge and runs north for 1,375 feet. Grassed percolation swales are required to collect, treat and dispose of the runoff from Sullivan Road, for the stretch of Sullivan Road adjacent to the Central Pre-Mix site. Runoff from roadway . improvments adjacent to other ownerships will be collected and disposed of through drywells Drainaae Calculations The raad improvements are separated mto three drainage basins. Basin I coilects runoff from the bridge north to Flora Pit Road. Basins II and III collect runoff from Flora Pit Road north to the end of the project. The drainage calculations for all basins and a basm map are attached 6asin I's runoff is presently collected by a Type "A" drywell The present condition caiculations show a peak flow of .SO CFS. The future condition calculations show a peak flow of 1 17 CFS. The Type uA" drywell will be replaced with a Type "B" drywell and a gutter depression will be constructed. The new drywell will be at a low point atong the curb return, with the end of the return being higher, helping to coliect the total flow from the basin (mlet calculations are attached). 6asins II and III drain south from the railroad bridge to a low point just north of the Flora Pit/Sullivan Road intersection. The plans show that the runoff will be collected by special curb inlets and be discharged into grass swales wdh a storage depth of 6-inches. Basin II's swale collects runoff from Sullivan Road and a portion of the Central Pre-Mix site. Basin III's swales collect runoff from Sullivan Road and the employee parking lot adjacent to the swales.

Disposal by drywell occurs only in the southern swale and after storage of runoff at a 6-inch depth. Swale sizes are shown on the plans. The attached bowstring caiculations show the swales are capable of storing the peak inflow while allowing a 1.0 CFS outflow (i'ype "B" dryweil). The chart below shows the peak flow, maximum storage volume required for mflow storage, and swale capacities. BASIN PEAK. Fk.OW INFLOW STORAGE STORAGE VOLUME VOLUME REQUIRED PROVIDED I I 2.97 C. F.

The attached calculations show that dual curb inlets are required to collect the street runoff. Two inlets at each station are needed due to the slope of the roadway and the need to channel the runoff water to the swales. The calculations show that all but .05 CFS will be coilected by curb inlets in Basin I11. This .05 CFS overfiow from Basin Iil is coilected by the curb miets in Basin II.

This is an experiment to determine if the concrete mix will be light (white) enough to possibly replace the use of white concrete in the future. We will use the same sack content concrete as specified but replace white cement with High Early cement which is lighter than normal Type 2. We will also use calcium chloride not to exceed one (1) percent. This should produce a mix as light or lighter than the sidewalks on the east side of Sullivan Road. Please acknowledge thia letter and return a copy to me. I hope the result is light enough, it could replace white in the future. It will save the County no less than $75-$85/concrete yard. Thank you for your co-operation. Very truly yours, IN7,,AND ASPHALT COMPANY Michael K Murphy President M/ su cc: Randy Waters Acknowledged by: C Date: An Equal Opportunrty Employer t . ~ . 11) The access road to the sand and gravel operation shall te relocated approximately 200 feet north of the c:xtsttng accoss location to elfminate a number of traffic conflicts lnvolving the exitfnq slow moving tnucks. Wtth the relocated extt, the existing two-way left turn lane may be used by the exlting truck traffic as an acceleration and/or storaqe lane prtor to entering the southbound Sullivan Road traffic stream. At the relocated exlt, sight distance !n both dlrecttons is moro than adequate and can be incorporatet into the development plan with mfntmum change !n the original proposal. 12) In the event the operator deternnines to remove the road to the south of the property in accordance wtth the agreement dated the 26th day of December, 1963, between Central Pre-Mtx Concrete Company end Acme Concrete Company and Spokane County, the operator shall: (1) Consttuct a 60' paved readway to give Spokane County access from Sullfvan Road on the West to the existing entrance to the Flora Road Shop S[te; (2) The altqnment of said road shall be constructed to the satisfacClon of Spokane County; (3) The point of access fronn Sullivan Road shall be approved by Spokane County. _Z7_ en. • ~ ~ p 7) The operation shall comply wlth emisston standards of the Spokane County Air Pollution Control Authority or succ4ssor aqency. In order to reduce dust emissions from the stte, access reads shall be paved, the parkinq areas and other roadw-ays shall be treated w[th a dust-controlling aqent, and non- operating areas retained ln veqetative cover. 8) Drainaqe channels lncludinq a dike alonq the north wall of the pit shall be constnucted to keep natural runoff from entering the pit area. The northerly dike shall be retained after rehabil[tation. In addition, fuel storage areas and service facilities ahall incorporate provlsions to pievent lubricants and petroleum products from contaminatinq either the pit area or drainage channels leading to the Spokane River. 9) In accordance with the operatlon and rehabilitatlon proposal, a landscape screen similar to that currently establlshed along the west boundary of the project shall be mainta lned along the west and south boundacies of the p!t area. Remaininq open sgace areas including stockpiled overburden needed for reclamation shall also he maintained ln veqets►tive covec. AToxious weeds of the site shall be controlled. Only pest[cides which would not disrupt aquatic life in the Spokane Riv+er or contar.,inate the water !n the aquifer may be u sed . 10) The pit and operations area shall be surnounded by a fence sufftclent to prevent unauthorized entry. The fertce shall conslst of a 6-foot high woven wtre fence with one-foot (3 strand8) of barbed wice on top (seven-foot "steel- guard" fence). The fence shall be installed prior to commoncement of opera- tlons and shall be maintained in qood condltion at all times. -.2 6- S ~ ~ . ~ Bonds for each successive phase after Phase 2 shall be negotiated with Spokane County officials having tu.tsdiction. Excavatton into the aquifer foc Phase 3 cannot proceed until Phase 1 has been backfilled to the expressed satl sfactlon of the Spokane County Planninq Director and the Spokane County Engineer (or Caunty offictals having iurisdlctton for Spokane County at the time) . Similarly, excavation lnto the aquifer of Phase 4 cannot proceed until Phase 2 has been backfilled to the expressed satisfaction of the above- listed officlals. In establishing the amounts of such bonds for Phases 3, 4, and 5, the Spokane County Planning Offtce and the Spokane County Enqlneer's Office or successor agencies shall conslder the cost of securtnq an adequate amount of proper backflll material, the success of prevtous rehabilitatlon efforts, and the Incentives fdr eontinued backfill operations. Bonds for these subaequent phases would be relased by Spokane County after the respective phases have been backfilled and rehabilitated to the sat- isfaction of Spokane County. 6) A phase may be oonsidered rehabilitated when (A) the slopes of the pit are qraded to less than a two to one s:ope and covered with 12" of topsoil (or overburclen), (B) the bottom of the pit area is filled to a point no less than five feet above the htgh water level of the aquffer with inert, non- pollutant materials, then keyed and covered with 12" of topsoil (or over- burden), and (C) vegetative Qrowth has been established on the slopes and floor of the rehabilttated area. A bond for rehabilitatton of a phase may be reduced if the primary obiecttve of covering the aquifer is achieved. -25- ~ ~5) Bonds for reclamation and guarantee of perfolmance for the sand and gravel operatlons shall be postedv►.?iEh Spokane Couniy as follows: (County Proposal) A bond to Spokane County in the amount of $31, 000 shall be posted for the entire pcoject prtor to the celease of tbe QertlflGate- -actma~y-Pefw#.t. fiuch bond would allow (1) excavation above the aquifer throughout the de- lineated areas in accordance with the rehabilitatton plan and (2) the opecation of the plant and stockpile sites. The term of the bond would be for the life of the sand and gravel operatton and would be released by Spokane County only after (1) the inining area was satisfactorlly rehabilitated in accordance with "approved" plans ar►d (2) the equtpment and stockpiles were removed. An addttional bond in the amount of $31, 000 shall be posted before excavatton into the aquifer for Phase 1. Such bond would be released by Spokane County only after Phase 1 was backftlled and satisfactorily rehabtli- tated. (Note: It is anttcipated that the amount of the bond for Phase 1 may be reduced if the primary ob)ective of covering the aquifer ts achteved.)

Other improvements to the site include paved roadways, paved stagmg areas and gravel surfaced staging and matenal stockpiling . areas. Drainage facilities are sized to store the first 1/2-inch of runoff, from the new paved areas, in grassed percolation swales. Drainage Calculations: There are two drainage basins for the office f asphalt plant site, these are shown on the attached drainage basin map. Basin A coliects, stores and disposes of runoff from the southwest portion of the sfte. Basin B coliects runoff from the remainder of the site and is the largest of the two basins The following table shows the impervious area, required storage volume, and storage volume provided for each basin. Only the runoff from the new paving is being collected and stored in grassed swales. The existmg pavmg, which drains onto the new pavement is exempt from being stored in a grass swafe prior to disposal, as per discussions with County Engineering staff. , Required Storage Storage Volume 6asin lrnpenrjous Area Are'a Provided A 23,150 S.

The two swale halves have the same bottom elevation of 1981.00 Two 18-inch CMP culverts provide fiow equalization between the swates. infiow calculations for each subbasin, using the bowstring method, was used to iderrtify the inflow into each swale haif and to faciiitate the sizing of the flow equalization culverts 6ased on the attached computation sheets, the approximate average depths during the 14 minute peak mflow to the swales are as follows: Depth in North swale = 6" - 0.5' Depth in South swale = 11 1/4" - 0 94' . The depth in the south swale from the peak 14 minute in flow with no transfer of flow between swales was computed to be 1.12'. The maximum ponding depth that will occur in the south swale during the 10 year storm event will therefore be between 1.12' and 0.94'. The total depth of the south swale is 1651. Therefore adequate ftee board has been provided in the south swale to accomodate the peak in flow for the short period of time between the peak and when equilization occurs in the two swales.

Other improvements to the site mdude paved roadways, paved staging areas and gravel surfaced staging and material stockpiling areas. Drainage facilibes are sized to store the first 1/2-inch of runoff, from the new paved areas, in grassed percolation swales. Drainage Calculations: There are two drainage basins for the office/asphalt ptant site, these are shown on the attached drainage basin map. Basm A collec#s, stores and disposes of runoff from the southwest portion of the site. Basin B coilects runoff from the remainder of the site and is the largest of the two basins The following table shows the impervious area, required storage volume, and storage volume provided for each basm. The detaiis show the sizes of each swale I . Required Storage * Storage Voturtte 6asin Impervious Area ` .Area Prouided . f A 21,390 S.F. 891.3 C F. 929 C.F.

The grassed swale for Basin B is spiit by an access road . The, two, swale hafves have the same bottom elevation of 1981.00. Two 1 S-inch CMP cuiverts provide flow ~ equaiization befinreen the swales.

This lane starts at the north end of the Spokane River bridge and runs north for 1,375 feet Grassed percolation swales are required to coilect, treat and dispose of the runoff from Suilivan Road, for the . stretch of Sulliwan Road adjacent to the Central Pre-Mix site. Runoff from roadway improvments adjacerrt to other ownerships will be collected and disposed of through drywells. Drainaae Calculations: The road improvements are separated into three drainage basins Basin I colfects runoff from the bridge north to Flora Pit Road 6asins II and III collect runoff from Flora Pit Road north to the end of the project The drainage calculations for all basins and a basin map are attached. Basin I's runoff is presently collected by a Type "A" drywell The present condition calculations show a peak flow of .80 CFS. The future condition calculations show a peak flow of 1.17 CFS. The Type °A" drywell will be replaced with a Type "B" drywell and a gutter depression will be constructed. The new drywell will be at a low point along the curb return, wfth the end of the return being higher, helping to collect the total flow from the basin (inlet catculations are attached) Basins II and Ill dram south from the railroad bridge to a low pomt just north of the Flora Prt/Sullivan Road intersection. The pians show that the runoff will be collected by special curb inlets and be discharged into grass swales wfth a storage depth of 6-inches. Basin II's swate collects runoff from Sulltvan Road and a portion of the Central Pre-Mix site. Basin lll's swales collect runoff from Sullivan Road and the employee parkmg lot adjacent to the swates.

The swales will provide the following storage volume: Basin II (5.5x39x.5) + (17x164x.5) + (3x14x.5) + (5.5x23x.5) + (4 x 164 x.5) +(5 x 132 x.5) +(3 x 9 x 5) = 1921 25 C F 2 2 2 Basin 111 North Swale . (44x16x.5) + (56x145x.5) + (13 x 12.5 x.5) = 839.25 C F. South Swale (55x 15x.5) + (56x 13.5x.5) + (32 x 11 x.5) = 966 50 C F Total Basin III = 1,005 75 C. F. 6asin ill has two swales praviding for storage of the first .5-inch of runoff The northern swale, upon reaching a storage depth of 6-inches, will overflow into the southern swale. Disposal by drywell occurs only in the southern swale and after storage of runoff at a 6-inch depth. Swate srzes are shown on the pians. The attached bowstring caiculations show the swales are capable of storing the peak inflow white allowing a 1.0 CFS outflow (Type "B" dryweil). The chart below shows the peak flow, maximum storage volume required for inflow storage, and swale capacities. BASIIV PEAK FLOW 111IFLOW STQIRAGE STORAGE VOLUME S VOLt1ME REQU1REa pROVtDED 11 2 97 C.

As described earlier, the street runoff is collected by special curb mlets along Sullivan Road The attached calculations show that dual curb inlets are required to coilect the street runoff. Two inlets at each station are needed due to the slope of the roadway and the need to channei the runoff water to the swales. The calculations show that all but .05 CFS will be collected by curb inlets in Basin III. This .05 CFS overflow from Basin III is collected by the curb inlets in Basin 11 SU6JECT PRQJECT NO. 3 ois~-cx~~o ~ BY-JP. t.0et&9NoPJ DATE ~ '3 0 -4 Z ~ ' ~~o SHEET NO.

This lane starts at the narth end of the Spokane River bridge and runs north for 1,375 feet Grassed percolation swales are required to collect, treat and dispose of the runoff from Suilivan Road, for the stretch of Sulirvan Road adjacent to the Central Pre-Mix sde. Runoff from roadway improvmerrts adjacent to other ownerships will be collected and disposed of through drywells. Draina4e Calculations• The road improvements are separated into three drainage basins. 6asin I collects runoff from the bridge north to Flora Pit Road. Basins II and III collect runoff from Flora Pit Road north to the end of the project The drainage calculations for all basins and a basin map are attached. Ae~ ~ 8asin I's runoff is presently collected by a Type ti~ywell. The present contlition calculatrons show a peak flow of .80 CFS. The ure condifion calculations show a peak flow of 1.17 CFS. The Type "A" drywell ' be replacsd with a Type "B" drywell and a gutter depression will be construct . The new drywell will be at a low point along the curb return, with the end of th turn being higher, helping to collect the total flow from the basin. Basins II and III drain south from the railroad bridge to a low point just north of the Flora Pit/Sullivan Road intersection. The plans show that the runoff will be collected by special curb mlets and be discharged mto grass swales with a storage depth of 6-inches. 6asin II's swale collects runoff from Su11Nan Road and a portion of the Central Pre•Mix site. Basin III's swales collect runoff from Sullivan Road and the employee parkjng lot adjacent to the swales. .
