Subject: Removal Request for the Brookhurst subdivision, Natrona County,Wyoming. ACTION MEMORANDUM

PURPOSE

This memorandum is to request Removal Action funding necessary to2liminate the threat posed by contaminated groundwater used for domestic waterpurposes at the Brookhurst subdivision, Natrona County, Wyoming.

BACKGROUND

The Brookhurst subdivision is located in an industrial area four mileseast of Casper, Wyoming in Natrona County (see Figure 1). Most of the lots inthis rural subdivision have been developed and the subdivision now containsapproximately 100 homes, the first of which was built around 1972 (see Figure2). The Brookhurst subdivision is bordered by the North Platte River on thenorth, several industrial facilities on the east and south, and by the LittleAmerica Refinery on the west (see figure 1).

Groundwater contamination, consisting primarily of elevated levels oforganic solvents, has been detected in private wells throughout the area (seefigure 2). Water for domestic purposes such as drinking, cooking, washing,and batning is supplied by private wells which tap into the unconsolidatedgroundwater aquifer directly beneath the subdivision. There is no publicwater supply system in the area.

Most of the wells in the subdivision have been completed into the base ofthe alluvial aquifer. The regional movement of groundwater in the aquifer isthought to flow north to northeast. The depth to groundwater is as shallow as20 feet on the eastern side of the subdivision. The primary water-bearingformation generally consists of alluvial gravel and sands that are highlypermeable, allowing the movement of volatile organics to the groundwater.Shale bedrock begins roughly at 55-60 feet. (The preceding observations havebeen made by EPA RCRA, Emergency Response, and Wyoming DEQ hydrogeologists whoare familiar with the area and are also based upon review of numerous welllogs maintained on Brookhurst wells).

The groundwater contamination may stem from several sources upgradient ofthe subdivision that use, or have used, solvents which are common degreasersused at many industrial and maintenance facilities. Furthermore, since theseptic systems found in the area are shallow and directly connected with thewater bearing aquifer, common chemicals and solvents discarded into thesesystems may also contribute to the groundwater contamination. In addition,unknown amounts of these solvents may have entered the groundwater throughpoor waste management practices.

As a result of a complaint from a Brookhurst resident, claiming that herhorses were sick from drinking the water from Elkhorn Creek which runs throughthe subaivision, the Natrona County Health Department, the State of WyomingDepartment of Environmental Quality, Water Quality Division (DEQ/WQD), and theRegion VIII EPA Office of Drinking Water, sampled some of the wells and tapsthroughout the subdivision from August through October, 1986. The results ofthis sampling effort revealed the presence of organic contamination in boththe well and tap water (see Attachment I for the sample results). Thespecific groundwater contaminants found in the water from the sampling effortinclude:

-Trichloroethylene (TCE)-Tetrachloroethylene (PCE)-1,1-Dichloroethane (DCA)-1,1,1-Trichloroethane (TCA)-Benzene

In adaition, two of the wells sampled contained trace amounts of Toluene,and Xylene. Concentrations of TCE as high as 214 ppb and concentrations ofPCE as hiyh as 90 ppb have been detected in some of the private wells. Thesite is not currently on the National Priority List (NPL).

THUEAT t

The above listed volatiles are hazardous substances as defined underSection 104 (14) of the Comprehensive Environmental Response, Compensation,and Liability Act (CERCLA) of 1980, and designated as such in 40 CFR, Parts117 and 302. According to EPA's proposed weight of evidence scheme for theclassification of carcinogenic potential, TCE ana PCE are classified asprobable human carcinogens. In addition, the EPA Carcinogenic AssessmentGroup (CAG) has established the carcinogenic potency of PCE and Benzene. EPAhas proposed a maximum contaminant level (MCL) of 5 ppb for TCE (as a primarydrinking water standard pursuant to the Safe Drinking Water Act). ProposedHCL's for other contaminants found in the Brookhurst wells include:

Proposed Maximum contaminant Level (MCL) (ppb)Irichloroethylene ( T C E ) 5Tetrachloroethylene (PCE) —1,1-Dichloroethane (DCA)1,1,1-Trichloroethane (TCA) 200Benzene 5

The levels of TCE, PCE and Benzene found in the groundwater present asignificant public health threat as potential carcinogens through ingestionand possibly inhalation when cooking or showering with the contaminated water.

The Public Health Service, Agency for Toxic Substances and DiseaseRegistry stated in an attached letter (see Attachment II ) that:

1.) An imminent and significant health threat exists because of thepotential toxicity and increased cancer risk associated with thelevel of benzene.

2.) The present levels of PCE and TCE increase the lifetime cancer riskfor those individuals drinking the well water from the area.

The data obtained to date has been analyzed by Dr. James Baker, EPARegion VIII Superfund Toxicologist. Dr Baker indicates that concentrations ofthe above contaminants found in the wells and taps in the subdivision,although highly variable, generally exceed the stated EPA 10-4 upper boundlimit of carcinogenic risk (see Attachments I and II).

Beginning the first week of October, Wyoming Governor Ed Herschlerauthorized the use of disaster funds to provide free bottled water to theresidents of the Brookhurst subdivision. Funding from the Governors disasterfund for the bottled water terminated Friday, October 17, 1985. The NatronaCounty Commissioners agreed to continue paying for the water through the endof October. Subsaquenty, the residents of Brookhurst could purchase waterfrom the City of Casper or from a private company at their own expense.

ENFORCEMENT (see attached)

PROPOSED PROJECT AND COSTS

The following Removal Actions are proposed to eliminate the immediatehealth risks associated with the current use of the contaminated grounclwater:

1. Provide bottled water to the residents of the Brookhurst subdivisionuntil a permanent alternate water supply can be provided. (Bottled waterwas provided starting 12/15/86 per verbal approval from Robert L. Duprey,Director, Waste Management Division, on 12/4/86.)

2. Install approximately twenty-five groundwater monitoring wells to helpestablish the aquifer characteristics and the extent of contamination.

3. Install a public water distribution system throughout the subdivision andconnect to the Town of Evansville public water supply system (see Figure3). The subdivision will require a peak water rate of about 1 GPM/unitor approximately 100 GPM. It is estimated that a 5-inch water main couldbe tied into the existing 12-inch water main near the Little AmericaRefinery offices and supply the required amount of water (see figure 3).Sizing of the distribution system will be based on per capita domesticwater use only.

Providing water to the subdivision from Evansville Water District willeliminate the immediate threat of exposing the Brookhurst residents to thecontaminated groundwater in a timely, cost effective manner. It is importantto note that the immediate threat can be removed by eliminating the currentexisting pathway of exposure (private wells accessing the contaminatedgroundwater source). However, this removal action may not eliminate thesource of the contamination.

Therefore, further remedial action at the site may be necessary. Thisproposed removal action, to the extent practicable, has been designed and willbe implemented to contribute to the efficient performance of possible longterm remedial measures. "Provision of bottled water will be discontinued afterinstallation of the public water system and will not interfere with thatportion of removal action or future remedial actions. Installation of thepublic water system is not inconsistent with possible future remedial actionsincluding source and groundwater cleanup actions.

The following costs are estimated for these Removal Actions:

ERCS Contractor (10 hrs/day = 450 hours)Salaries

Response Manager- $55/hr x 450 hrs = 24,750Computer Tech - $33/hr x 450 hrs = 14,850

$ 60,625

ERCS SubcontractorsCold water dispenser:

$1.00/mo. x 100 homes x 6 months = 600

Bottled water:$3.75/bottle x 8 bottles/mo.x 100 homes x 5 mo. = 18,000

Groundwater monitoring wells:25 x $3,000/well = 75,000

Town of Evansville tap fee:$1000/home x 100 homes = 100,000

Engineering Costs = 15,000

Pipe laying = 250,000

$458,600

Total ERCS and ERCS Subcontractor Costs $519,225

Brookhurst Subdivision

On October 20, 1986, Tom Williams, Matt Langenfeld, and myself left Cheyenne tcgo perform on-site inspections and groundwater monitoring at the Brookhurst Subdivi-sion. We met with Mike Young from Lander and Kurt King from Sheridan. LarryRobinson was on-site late Monday and early Tuesday.

Langenfeld and Norman met -with Mrs. Burkhart to determine if permission had beesgranted to sample some of the wells in the Brookhurst area. The specific sites weregiven to Burkhart previously. Two out of the 'fifteen sites would not be availablefor access.

Williams, Langenfeld, and Young proceeded to sample. Details on the groundwatersampling will be provided later.

King and Norman proceeded to perform on-site inspections of the commercialfacilities which are adjacent to and south of Brookhurst. The following is adescription of those on-site investigations.

TRIP REPORT

TO: File

FROM: Thomas S. Norman, Chris Norman

DATE: September 26, 1986

SUBJECT: Brookhurst Subdivision

General

On September 24, 1986, Tom Norman and Chris Norman of the WQD performed an on-site inspection and evaluation of the complaint at Brookhurst Subdivision, east ofEvansville.

The WQD personnel met with Ken Crowl of the Natrona County Health Department anddrove around the Brookhurst Subdivision. Crowl familiarized the WQD with the areaexplaining where the complaints were originating and explaining the type of commer-cial operations in the area. Crowl departed.

The WQD personnel then met with Linda Burkhart and . Anna Neumiller fromBrookhurst and Bob Stone of EPA RCRA at Burkhart1s home. Burkhart showed pictures ofthe area and potential sources of pollution. Stone explained the situation as he sawit. Since the WQD's time was limited, Stone suggested we perform on-site visits atNeuman Trucking, Fleischli, Kansas-Nebraska and Little America.

WQD explained that their plans were to obtain an overall picture of the area,visit specific commercial sites that are suspected of having problems, follow-up oncomplaints concerning unauthorized ponds and discharges, and take a well sample frorathe "worst" area. The well sample will provide the WQD with data as to whether ornot there is a contamination problem.

Sivalls

WQD personnel proceeded to Sivalls and met with Mike Donathon. Sivalls is anoil tank distributor with a manufacturer in Texas. The previous owner used thefacility to manufacture tanks on-site up until November 1984 at which time the placewas shut down. Sivalls bought the property in January 1986 and only uses it for dis-tribution purposes. A well is located on-site but the water is only used for thetoilets. Bottled water is used for potable use.

The WQI) personnel then proceeded to Ncuman Trucking, 6050 E. Yellowstone (826C2)and met with Phil Hanford. Burkhart had stated previously that Neuman was discharg-ing into a pond that was located on 84~Lumber. 84 Lumber is closed down. New.-r^nTrucking services their vehicles at this site. Waste oil is recycled and burned intheir heating unit. Solvents are handled by a recycler. Floor sunps are cleaned byColeman, a local septic hauler.

We proceeded to inspect the outside of the building and Mr. Hanford did notaccompany us. An area was found in the NE corner along the 84 Lumber fence wheredumping of waste oil had occurred. Runoff appeared to carry the oil over to a stonnrunoff pond that is located on 84 Lumber's property. The pond had a little water init with some oil staining and floating oil.

Another oil saturated area was located in the NW corner of Neuman's property.

Hanford was notified of the violations and Tom stated a letter of violaticnwould be coming requiring clean-up of the area. Hanford said he was unaware of tieoil problem.

Neiman has a well on-site that is used for toilets. Bottled water is used fordrinking.

Fuel for their trucks is located above ground.

Ton and Chris feel that the present violations are not of the magnitude thatwould cause a problem in the Brookhurst area. However, any pas£- spills, discharges,or underground facilities could be causing a problem.

Fleischli

WQD personnel investigated Fleischli Oil which is immediately west of NeumanTrucking. We met with Frank Cushatt (6000 E. Yellowstone, 82636). Cushatt showedus their building which is used for servicing their trucks and also for storing theirbulk products (oil, grease, anti-freeze). Waste oil is picked up by a recycler.Coleman cleans the sump pits. Solvents are managed by a recycler. Water from thesumps are disposed in a septic system that is separate from the domestic wastes. Thebulk storage area has no drains.

The exterior of the facilities found a storm drainage system going into a stormpond. (Drainage is a common problem for these commercial facilities on the southside of the railroad.) The storm pond was also receiving fuel spillage for a fuelloading dock. The pond had diesel in it. The fuel tanks are above ground. Thepond also was designed as a SPCC facility. Cushatt was informed of the violation andWQD stated a letter would be coming. The pipe entering the pond did have a gatevalve which could be closed to prevent immediate discharges. Cushatt requested whathis options were. Tom stated that a tank for containment is recommended or else anoil/water separator with a discharge permit.

A well is located on site for toilet flushing. Bottled water is used for pota-ble purposes.

;; i t i- th:it could cilhiT lie li'-iking, :;pilli'iJ, or dumped in the p.ist which .111 on-^:iev i s i t would not detect. A p.irti.il listing is as follows:

Cameo Constructj.onNalco Chemical Co.Wyco PipeDowell ChemicalMarkland TruckingPermean Corp.Septic Co.84 LumberCMSNat coBurkeAbbotVan Water & RogersUnivarJohnston's Fuel LinersFilling Station

Well Sample

A well sample was taken at Mr. Naab's residence which is located along the BNURic the SW corner of the subdivision. This sample along with the wells tested atPitzers, Burkharts, and Little America should give a good cross-sectional view of thearea.

Naab stated that he uses his well only for toilets and washing. Bottled wateris used for potable purposes. Naab has a softner and a GAC filter (?) and the wateris still undrinkable.

The water samples out of the well have heavy odors of sulfates and would be dif-ficult to drink from the odor stand point.

Six samples were taken from Naab's well for VOC and extractables. The well wasbaled. The baling disturbed the well casing and caused some "rusting" to enter thewell and samples. The well was PVC and enclosed in a shed. The well did not have asanitary cap.

DATE: October 3, 1986

SUBJECT: Trip to Brookhurst Subdivision, Evansville, Wyoming

On September 24, 1986, Tom Norman and I traveled to the Brookhurst Subdivision,Evansville, Wyoming. Residents of the subdivision have complained about water qual-ity and the activities of business establishments in the area.

At 8:30 am, Tom and I met with Ken Growl, Natrooa County Environmental Health.Mr. Crowl described the situation and gave us a tour of the area. After the tour,Tom and I proceeded to meet with Linda Burkhart, resident, and Bob Stone, EPA. Mrs.Burkhart and Mr. Stone gave an update of the situation and showed pictures of thearea businesses.

Several area businesses were then visited.

Nuemann Transit: Nuemann Transit was visited and the site inspected. Nuemaon Tran-sit is dumping oil and asphalt residue into a drainage which flows onto an adjoiningproperty. It appears that Nuemann is also dumping used crankcase oil on their backlot. Although a threat to groundwater is present, it is not felt that this problemis major. An LOV is to be sent regarding cleanup and halting the activity.

Fleischli Oil Company: Fleischli Oil Company was visited and the site inspected.Fleischli Oil Company has a storm water retention pond behind its fuel storage tanks.A drain from the loading rack pad drains to the pond causing a scum layer and a prod-uct layer on the water surface. Again, a threat is present but it is not felt thatthe threat is major. An LOV will be written to address cleanup of the pond. Analternate spill plan will be requested.

KN Energy, Inc.: KN Energy is a gas cleaning plant. Outside is an oil storage pond.This pond holds any oil captured in the cleaning process. The present pond was con-structed in late 1984. Previously KN Energy disposed of this waste in an unlinedsoil pond (1965-1984). When the new pond was constructed, the old pond was filled inwith soils. An LOV will be sent to KN Energy regarding construction without a permitand threat to groundwater.

Little America Refining Company: LARCO was visited and a short meeting was held withLarrv Thomas, Sid Anderson, and Jim Limes. The meeting centered around the groundwa-

ter invest i Cation bein^ romiuirted .it ti>Li LAKCO site. Concerns were --xprL'Ssed re^sr'i-in^ the migration of disuolvo-j organic constituents tuwnrd the Erookiim ut wells. Ashort tour of the facility followed. LARGO has subsequently sampled (.9/25/86) theperimeter monitor wells and wi,ll analyse the samples using EPA Methods 62* and 625.

Well sampling: Following the site tours a domestic well sample was taken. The wellsampled was from Dennis Maab's well. The bailer was washed with acetone followed bysoap, then rinsed with well water from an outside tap. The well was then evacuatedby running water out of the tap. The water had an H2S odor and had iron particles.Samples were then bailed out and collected in 30 ml septom bottles. A base neutralsample (EPA 625) was collected from the outside tap. The samples were placed in acooler, chilled and delivered to the Water Quality Lab at 1:22 pm 9/25/86.
