PO Box 3200 Silverdale, Wa. 98383 July 1998 ' SITE SUMMARY MASON COUNTY FIRE DISTRICT#2 7/98 On July 9, 1998 Cascade Environmental Service Inc. (CES)under contract with Mason County Fire Department #2 (MCFD)began demolition and decommissioning of the fueling site at NE 460 Old Belfair Highway in Belfair, Washington. The site consisted of two 1000 gallon underground storage tanks (UST), one diesel and one gasoline, two distribution pumps, concrete fueling slab, and metal awning. The fueling site was located on the east side of the main building adjacent to a parking area. The property layout is depicted in Drawing 1 within this report. Richard Verhelst of CES was site assessor, UST decommissioning supervisor, and machine operator for this project. Sandy Verhelst of CES and Robert Barkley of Barkley Construction assisted under the supervision of Richard. Machinery used on site consisted of a John Deere 310 rubber tired backhoe, a Melrose Bobcat skidder/loader with a concrete breaker hammer attachment and a Ford/New Holland skidder/loader. The first order of business at the site was to explain the safety plan to all parties on site. Following the safety meeting, Robert Barkley began removal of the distribution pumps, demolition of the concrete pad and pump island, and of dismantling the metal awning, the portions of the project his company had contracted to perform. Richard assisted Robert in dismantling the awning. When that had been dismantled and all of the concrete had been shattered into smaller pieces, Richard used the backhoe to pull the pieces from the work area and to stockpile them to be hauled away at a later time. The preceding operations expended the entire day to complete. On July 10, 1998 operations began at 08:00. The same workers were on site, Richard, Robert and Sandy. The first area to be addressed was the pump distribution location. The gasoline and diesel distribution pumps had been mounted adjacent to each other therefore one soil sample was collected beneath this area. The sample was collected from a depth of 24" below grade surface (BGS). A 3" hand auger was utilized for collecting the samples. Throughout the sample collecting phases, the augers utilized were decontaminated prior to each sample being collected. Washington State Department of Ecology(DOE) decontamination procedures were followed throughout the project. Each sample collected was placed into its own 4 oz.jar. The sample jars were supplied by Transglobal Environmental Geosciences (TEG) Laboratory located in Lacey, Washington. All samples were placed into a cooler with ice immediately following the sample collection and labeling. The next area to be sampled was the gasoline supply line halfway between the pump and the UST. This sample was collected from a depth of 24" BGS directly below the supply line. Cascade Environmental Service Inc. The next phase of the project was to excavate the soil from above both USTs to allow the supply lines to be drained back into the USTs and removed. Once this was accomplished the supply line bung on each UST was plugged and the cleaning of the USTs began. The USTs were cleaned by means of a high pressure washer utilizing a solution of water and trisodium phosphate (TSP). The TSP was introduced to the USTs through the washer and then final rinsed with clear water. The residual product/soap solution was pumped from the USTs into 55 gallon drums via a pneumatic pump. Final disposition of all residual product is recycling at Petroleum Reclaiming Service, Inc., (EPA ID #WAD 980511729) at 33801 7th Ave. S, Seattle, Washington 98108. Upon completion of extracting all liquids from the USTs, inerting of the USTs began. Bottled Co2 was introduced into each UST to displace the oxygen to a safe, non explosive level. A level of below 6% oxygen was achieved in each UST. Upon completion of inerting both USTs the remaining piping, (vent pipes)were removed and excavation of the soil surrounding the USTs commenced. The soil on the north side of the gasoline UST was removed to a level nearly equal to the bottom of the UST. Rated steel chains were attached to the UST and the UST was hosted out of the excavation by the backhoe. The UST was inspected for signs of leakage. None were apparent. The UST was staged out of the working area on a grassy location and blocked to prevent movement. A soil sample was collected from the midway point of the north wall of the excavation at a level of 55" BGS. Another sample was collected from the bottom of the excavation at a point directly below where the UST had been removed. The sample was collected from a depth of 95" BGS, which equates to 6" below the bottom of the UST. Following collection of the bottom sample of the gasoline UST area the samples from beneath the midway point of the diesel supply line was collected. This sample was collected at a depth of 24" BGS. The diesel supply line was removed following the collection of the previous sample (diesel supply line sample). The next phase of the project entailed the removal of the diesel UST. After excavating the soil from around the diesel. UST the same procedure used to remove the gasoline UST was followed to remove the diesel UST. The diesel UST was inspected for leakage (previously Rich Hienrich of the MCFD had explained to Richard that the diesel UST had instances of water in the UST but no record of loss of diesel). The UST showed signs of rust deterioration but not leakage. After removing the diesel UST the next sample to be collected was the bottom sample from directly beneath the UST at a depth of 97" BGS which equates to 8" below the bottom of the UST. The last excavation sample was collected from the south wall of the excavation at a depth of 56" BGS midway on the wall. The remaining samples were collected as discreet composite samples from the stockpiled excavation soil. A total of three composite samples were collected. Field tests consisting of sheen testing, olfactory presence testing, and dye testing were performed on all samples collected. All tests proved negative on presence of petroleum hydrocarbons. Laboratory analysis of samples provided showed non-detect (ND) of petroleum hydrocarbons. Findings and quality control standards for laboratory analysis are provided within the report. Cascade Environmental Service Inc. The USTs and all piping were transported to Airport Auto Wrecking on Highway 3 S, Port Orchard, Washington for determination of fate. One UST will be transported by CES to Hansen Farms in Milton-Freewater, Oregon for use as a trailer mounted diesel tank. CES will supervise the disposition of this tanks future use and shall assure proper identification of the tank for future use. The remaining tank and all piping was cut up for metal recycling. Concrete debris from this project was transported to Kitsap Reclamation in Bremerton for recycling. Backfill for the excavation was supplied by Kitsap Reclamation in Bremerton. All soil samples were analyzed for levels of total petroleum hydrocarbons (TPH). All results of laboratory tests concluded levels of TPH to be non-detect. Based upon the results of the analytical testing (non-detect) it is in the opinion of Cascade Environmental Service Inc. that no further action is necessary at this site in regards to decommissioning of the subject UST.

BRIEF DESCRIPTION OF SURROUNDING LAND USE This site is located approximately 1/2 mile north of Belfair on the east side of the Old Belfair Highway. The surrounding land use is rural homes and farms. Approximately 1/3 mile west of this site is the Union River which flows into Hood Canal. Medium to heavy density wooded land immediately adjoins the site to the east and on the east half of the south side. There are no known wetlands within the immediate proximity to the site. SUMMARY OF FIELD SAMPLING ACTIVITIES CONDUCTED There were a total of ten soil samples collected from this site. Sample# 7998-1 was collected from 1 foot below grade surface(BGS)beneath the distribution pumps. Sample#7998-2 was collected at the midway point half way between the gasoline distribution pump and the gasoline UST at 24" BGS beneath the gasoline supply line. Sample # 7998-3 was collected from a level of 55" BGS from the north wall of the excavation at the midway point of the gasoline UST. Upon removing the gasoline UST from the excavation, Sample# 7998-4 was collected from directly beneath the bottom midway point of the UST. This sample was collected at a depth of 95" which equates to 6" below the bottom of the gasoline UST. The next sample collected was # 7998-5. This sample was collected from beneath the midway point of the diesel supply line at a depth of 24" BGS. Sample# 7998-6 was collected following the removal of the diesel UST from beneath the midway point of the UST at a depth of 97" which equated to 8" below the bottom of the UST. The final sample from the excavation was collected from the UST midway point of the south wall at a depth of 56" BGS. Cascade Environmental Service Inc. 7/98 The remaining samples, 7998-8, 7998-9, and 7998-10 were all collected from the excavation stockpiled soil. The stockpile soil samples were collected as composite samples to assure proper characterization of the stockpiled soils. All samples were collected utilizing a 3" hand auger. All soil sampling instruments were decontaminated between samples using industry standard guidelines. Samples were transported to the analytical laboratory in laboratory furnished sampling jars. All samples were placed in a chilled cooler, packed with ice and shipped to the laboratory for analysis.
