We revIewed the envIronmental checklist and have the followmg comments Underl!round Storal!e Tanks: Installation of new underground storage tanks must meet the reqUirements of the state underground storage tank regulatIOns (Chapter 173-360 WAC) CopIes of these regulatIOns and reqUired forms are available from the Department of Ecology by calling (360) 407-7202, or toll-free m state 1-800-826-7716 A notice of mtent to mstall tanks must be filed wIth the Department of Ecology at least 30 days prior to mstallatlOn. Withm 30 days after comIng mto service, the tanks must be regIstered wIth the Department of Ecology on a state notIfication form. The supervIsor on-SIte durIng the InstallatIOn must be licensed by passing an exam admmistered by the InternatIOnal FIre Code InstItute, or by another state wIth WhICh Washmgton has a recIprocIty agreement. New tanks and any connected pIpIng must be protected from corroSIOn by eIther a cathodIC protectIOn system, or by bemg constructed or coated wIth a non-corrOSIve matenal such as fiberglass An acceptable method of leak detectIOn must be employed, and the tanks must be eqUipped with spIll preventIOn and overfill protectIOn eqUipment. Stage I vapor recovery eqUipment IS required on all new gasoline dISpenSIng facilitIes WIth a total gasolIne nom:nal stDrage capaCity greater than 10,000 gallons. Also, a certified Stage II vapor recovery system IS reqUIred for these facilitIes in all Western WashIngton counties (Chapter 173-491 WAC) Under the Ulllform Fire Code, other local permIts may be reqUired for the InstallatIOn of underground storage tanks The local offiCial charged WIth admInistratIOn of the Code should be contacted regardIng the permIt requirements. A notice of Intent to permanently close tanks must be filed WIth the Department of Ecology at least 30 days pnor to closure The closure must be completed withIn 60 days after expIration of the 30-day notice unless a wntten request for an extensIOn is approved (Chapter 173-360 WAC) The on-SIte supervisor, providIng tank-clOSIng servIces, must be licensed by passIng an exam admilllstered by the International FIre Code Institute, or by another state With which WashIngton has a reCiprocIty agreement. Withm 30 days after c1osmg, a permanent closure checklist form must be proVIded to the Department of Ecology by the owner The checklist must be SIgned by the certified supervisor that was on-site dunng the closure '~~ A site assessment to determine whether contaminatIOn has occurred must be completed by a profeSSIOnally qualified person certified by the International Fire Code Institute The Department of Ecology's mInimum reqUirements for samplIng for contamInation m the excavatIOn area are outlIned In a published guidance document. ThIS document, forms, and regulations are aVailable from the Department of Ecology by calling 1- 800.;-826-7716 WithIn 30 days after completIOn, the person that performed the site assessment must prOVide Ecology a SIte assessment checklist and results ofthe~~g. 0 r., Ms Kathy Wolf January 7, 1998 Page 2 If contaminatIOn of sOlI or groundwater IS readily vIsible, or IS revealed by sampling, the Department of Ecology must be notified wlthm 24 hours by the owner and withIn 72 hours by the service proVIding supervisor Contact the EnVironmental Report Trackmg System Coordinator at the Southwest RegIOnal Office at (360) 407-6300 For assistance and mformatlon about subsequent cleanup and to Identify the type of testIng that will be reqUired contact the Toxic Cleanup Program at the Southwest Regional Office at (360) 407-6300 The Department of Ecology reqUires the results of the site assessment be maintained for five years after comp let IOn of permanent closure or change- In-servIce. We recommend that the records be ke{>t m the property file mdefillltely for any future property owners to fulfill liabIlity reqUirements under the Washmgton Model Toxlcs Control Act. If storage tanks contam dangerous or hazardous wastes as defined in Chapter 173-303 WAC, please contact Ecology's Southwest RegIOnal Office, Hazardous Waste and Toxics ReductIOn SectIOn, for closure reqUirements. Under the Umform Fire Code, other local permIts may be reqUired for the closure of underground storage tanks. The local offiCIal charged with admInIstration of the Code should be contacted regardIng tIie permit reqUirements. Water Qualitv: ErOSIOn control measures must be in place pnor to any c1earmg, grading, or constructIOn. These control measures must be effective to prevent soil from beIng carried mto surface water by stormwater runoff Sand, silt, and soil will damage aquatIc habItat and are consIdered pollutants. Any discharge of sediment-laden runoff or other pollutants to waters of the state IS In VIOlation of Chapter 90 48, Water PollutIOn Control, and WAC 173-20IA, Water Quality Standards for Surface Waters of the State of Washington, and IS subject to enforcement action. Proper disposal of constructIOn debris must be on land in such a manner that debris cannot enter the natural stormwater drainage system or cause water quality degradation of state waters. Proper erosion and sediment control practices must be used on the constructIon site and adjacent areas to prevent upland sedIments from entenng the natural stormwater draInage system. All areas dIsturbed or newly created by constructIOn actIvities must be revegetated, use bioengineering techniques, use clean durable nprap, or some other eqUivalent type of protectIOn against erosion when other measures are not practical. After completIOn of this proJect, there is a likelihood that SlOrmwater runoffwiii contain increased levels of grease, Oils, sedIment, and other debris. It is recommended that stormwater treatment deVIces be installed so that any dIscharge will be appropnately treated to remove these substances. RoutIne mspection and maintenance of all sediment and erosion control deVIces IS recommended both durmg and after development of the site A sedImentatIOn and eroSIOn controll?lan for the project site may be required and must be developed by a licensed engineer The plan must be Implemented before and during constructIOn. The sIte must be carefully mOllltored to determIne effectiveness of the plan. The plan must be upgraded as necessary during the constructIOn penod. During construction, all releases of oils, hydraulic fluids, fuels, other petroleum products, paints, solvents, and other deletenous matenals must be contained and removed m a manner that will prevent theIr discharge to waters and soils of the state. The cleanup of spills should take precedence over other work on the SIte For All Developments WIth On-SIte Systems for Domestic Waste Water Proposed. All developments dischargmg to the ground VIa on-SIte disposal systems must demonstrate compliance WIth the Water Quality Standards for Ground Waters of the State of Washmgton, Chapter 173-200 Washington AdmInIstratIve Code (WAC), including antIdegradation requirements. A hydrogeologIC impact assessment wIll assess ImpactS to ground water A hydrogeologIC Impact assessment must be completed by the applIcant pnor to the start of constructIOn (in order to mitigate potential impacts) if potential Impacts to ground water from the proposed project are unknown. ... Ms. Kathy Wolf January 7, 1998 Page 3 The Ground Water Quality Standards establish a maXImum ground water cntenon of 10 mIllIgrams per liter (mg/L) llltrate (as llltrogen) (N)) When background concentrations are below 10 mg/L N, anti degradatIOn regulatIOns are intended to protect background water quality A substantlalmcrease in the ground water concentratIOn of llltrogen due to development IS not acceptable Mitigation may be reqUired to meet these regulatIOns. MitIgatIOn options include' * Reduce the denSIty of the development to allow a maximum increase of 2 mg NIL above background conditions. * PrOVIde additional treatment (mtrogen removal) before discharge to the drainfield(s) to allow a maXImum mcrease of 2 mg NiL above background condItions. * OR (preferred) connect the system to a sanitary sewer For Proposed Large On-SIte Systems. WAC 173-240-035 prohibIts large on-SIte systems except under those extraordmary CIrcumstances where no reasonable alternatives eXISt. Ecology review and approval IS reqUired for all septic tank systems exceedmg an ultimate deSIgn capacity of 14,500 gallons per day (gpd) at any common pomt. Ecology approval IS also reqUired for a mechamcal treatment system followed by subsurface disposal exceedmg 3,500 gpd (WAC 173- 240-020). * A large on-site facility must be owned, operated and mamtaIned by a publIc entity ConstructIOn oversIght must also be conducted by the oWlllng public entity * The proJect also reqUires a State Waste DIscharge PermIt from Ecology, Chapter 173-216 WAC For All Development Proposed m the Puyallup RIver BaSIn. There IS a total maXImum daily load (TMDL) established for biochemical oxygen demand (BOD) and ammoma m the Puyallup RIver BaSIn. All dIschargers to the nver have established waste load allocatIOns for BOD and Ammoma. Due to the proXImIty ofthis development to the nver, a hydrogeologIc assessment IS reqUired. The Impact of any loadmg from this development to the nver is prohibIted unless an allocatIOn IS speCIfically gIven wlthm the TMDL.

AIr and water erosion of soils during grading and filling is a possibility, but is not anticipated to be sigmficant -4- 5892.002 [LH/sm] EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT g. About what percent of the site will be covered with impervious surfaces after project construction. Approximately 76 percent of the site will be covered wIth impervious surfaces h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any' A temporary erosion and sedimentation control plan will be designed in accordance wIth the standards of the City of Yelm. This temporary erosion and sedimentation control plan may include the use of a filter fabric fence and/or other accepted methods to effectively mItigate the impact of soil erosion on site and on adjacent properties Following the completion of the grading, fillIng and construction phases, the undeveloped areas will be formally landscaped The landscaped areas will include a variety of ground cover, shrubs, and trees that are either indigenous to or suitable to the northwest climate These landscape plantings will also assIst in erosion control 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities, if known. The project may result in an increase in minor emissions to the air, both during and following construction completIon. During constructioD, there will be construction equipment exhaust that will be emitted from vehicles using gasolIne or dIesel fuels These emissions will be temporary in nature and, in our opinion, will not have a lasting or harmful effect on the project or adjacent properties There may also be airborne dust particles affecting air quality, principally during the filling and grading phase of this project. The amount of airborne dust particles will be mimmal -5- 5892.002 [LH/sm] EV ALUA TION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT Following construction, the project will generate automobile vehicle emIssions This will increase the amount of suspended particles, carbon monoxide (CO), nitrogen oXIde, hydrocarbons, and other tYPIcal pollutants The vehicle emIssions will be assocIated wIth the exhaust fumes from patron automobiles and transport trucks associated with a food market and retail gasoline sales facility b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. The only off-site sources of emIssions or odor that may affect thIS proposal would include exhaust emissions from vehIcles traveling on the abutting streets, but these are not expected to impact this project. c. Proposed measures to reduce or control emissions or other impacts to air, if any: To mimmize Impacts to the air by gasoline products, Stage I and Stage II vapor recovery systems will be utilized at the tanks and product dispensers Stage I recovers the vapors that are displaced during the dehvery of fuel by truck trailers, and Stage II will reduce vapor release to the air typically associated WIth refueling of vehicles 3. WATER a. Surface Water: 1. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, salt water, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. Yelm Creek is approximately 650 feet west of the property line 2. Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans for this work. No -6- 5892.002 [LH/sm] EV ALUA TION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT 3 Estimate the amount of ml and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected.

Give general description, purpose, and approximate quantities, if known. No 5. Does the proposal lie within a lOO-year floodplain? If so, note floodplain location on the site plan. No 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No b. Groundwater: 1. Will groundwater be withdrawn, or will water be discharged to groundwater? Give general description, purpose, and approximate quantities of withdrawals or discharges, if known. On-site stormwater will be collected by catch basins and storm hnes with a metered release through an oil/water separator that will then infiltrate into the subsoils 2. Describe the underlying aquifer with regard to quality and quantity, sensitivity, protection, recharge areas, etc. The site IS located in an aquifer recharge area and the exact nature of the quality and quantity of water is unknown. AqUifer is believed to be shallow and is sensitive to pollutants In order to minimIze any -7- 5892.002 [LH/sm] EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT potential impact to the aquifer recharge, the septic system will be desIgned to meet or exceed DOE and Thurston County standards In addition, the storm system will also meet or exceed DOE and the City of Yelm standards 3. Describe waste material that will be discharged into or onto the ground from septic tanks or other sources, if any (such as domestic sewage; industrial byproducts; agricultural chemicals). The site will utilIze the existing on-site septic holding tank system to manage all domestic sewage The system will hold approximately 300 to 600 gallons per day of domestIc output. ThIs type of septic holding system typically requires frequent pumping m order to accommodate new output at a regular rate The on-SIte sewage disposal system will be designed by a licensed septic designer/engineer in accordance with Thurston County standards Eventually, when the City of Yelm upgrades the capacity of their sewer treatment plant and formally extends the sewer service boundary, the applicant will connect to the City of Yelm sewer system Waste materials that could potentially enter the ground include unspent hydrocarbons from the parking lot surface runoff through the on-site stormwater collection system. c. Water Runoff (including stormwater): 1. Describe the source of runoff (including stormwater) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. There will be stormwater runoff during the ramy periods of the year from both the developed impervious surfaces and from the pervious landscaped areas The majority of the stormwater runoff will occur from rooftops, parking, maneuvering areas, and walkways on the site Stormwater from these areas will be collected into catch basins and conveyed to the oil/water separator, then runoff will be routed to an infiltration gallery The system will be deSIgned to handle and treat all stormwater per the Department of Ecology Stormwater Manual and as required by the City of Yelm standards -8- 5892.002 [LH/sm] EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT Minor amounts of stormwater runoff may also occur on the landscaped areas of the site Because these areas are permeable, water runoff from these areas is anticipated to be considerably less than that from the developed areas Landscape plantings will promote soil stabilizatIon and assist in minimizing stormwater runoff impacts from these areas 2. Could waste materials enter ground or surface waters? If so, generally describe. Without the mitigation outhned in No 7 Environmental Health, and No 3 d. below, groundwater impacts are a possibility d. Proposed measures to reduce or control surface, ground and run off water impacts, if any: There are a vanety of measures whIch are proposed to reduce or control surface and runoff water impacts Many of these have been described above In summary 1) A temporary sedimentation erosion control plan will be prepared and approved prior to construction and will be satisfactorily maintained until construction is completed and the potential for on-site erosion has passed. 2) All on-site stormwater will be collected and conveyed through an oil/water separator and discharged to an infiltratIOn gallery All on-site stormwater runoff from the fueling pad and the concrete tank slab will be collected separately and piped to a single underground holding tank. 4. PLANTS a. Circle types of vegetation found on the site and list specific species: deciduous tree: alder, maple, aspen, other evergreen tree: fir, cedar, pine, other shrubs grass pasture crop or grain -9- 5892.002 [LH/sm] EVALUATION FOR AGENCY USE ONLY TO BE COMPLETED BY APPLICANT wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other water plants: water lily, eelgrass, milfoil, other other types of vegetation b.
