Sampling and Analysis Plan
Reeder Pistol Range
Ashland, Oregon
Prepared for
City of Ashland
FEBRUARY 1998

CH2MHILL
SECTION 1
Introduction
This Sampling and Analysis Plan (SAP) presents CH2M HILL's approach for sampling the
Reeder Pistol Range (site) located in Ashland, Oregon. The purpose of the investigation is
to collect information on the concentration of lead in site soils to determine if and to what
extent lead has been released to site soils during pistol range use.
Background
The Ashland Police Department wishes to terminate the permit issued by the Forest Service
for the City of Ashland's use of the pistol range. The Forest Service informed the City that
trader the terms of the permit the permit holder is required to restore the site. The
environmental issue associated with restoration of the pistol range is to address if and to
what extent lead is present in site soils as a result of pistol range use. CH2M HILL was
retained by the City of Ashland to develop a sampling plan to determine the lead
concentrations in site soils.
Site Location, Topography, and Hydrology
The site is a pistol range used by the Ashland Police Department located next to Ashland
Creek above Lithia Park in Ashland, Oregon. A location map for the site is shown on Figure
1.
The site is partly on City of Ashland property and partly on United States National Forest
land. The site is a level meadow 5 to 10 feet above the banks of Ashland Creek. The
topography on each side of the site is a steep canyon where Ashland Creek cuts through the
Siskiyou mountains. A site map is shown on Figure 2.
The site appears to be sufficiently above the elevation of Ashland Creek that it was not
affected by the local flooding that occurred in late December 1996 and early January 1997.
During a site visit by CH2M HILL, no evidence of flooding at the pistol range was observed.
By comparison, areas in Lithia Park still show evidence of flooding such as silt on roadways
and other park areas, damaged bridges and damaged roadways.
Site History
No specific records on Pistol Range use are available from the City. The following
information on site history was obtained from interviews of Ashland Police Department
personnel:
· Use of the Reeder Pistol Range began around 1967. A map of the site as originally
constructed is shown on Figure 3.

For the last 10 years, the City used the range three times a year with 1,500 rounds
discharged each time.
From 1967 to 1988, the City used the range one time a year with 1,000 rounds discharged
each time.
The primary use of the range was for pistol shooting, however the range was also used
for a limited amount of skeet shooting. The City estimates that approximately 2,000
rounds were discharged during skeet shooting.
The asphalt shooting lanes and asphalt pad were constructed by the City in 1992 to
provide a paved surface for shooting activities.
Lead was removed periodically for reuse as fishing weights by local fishermen. The
amount of lead removed is not documented.
SECTION 2
Sampling and Analysis Procedures
Sampling Approach
The sampling approach developed for this investigation is to collect and analyze soil
samples from the range berm, shooting lane areas, and the open area north of the asphalt
shooting lanes. These results will be used to determine the lead concentration in site soils.
These data will be used to determine if the concentrations of lead in site soils pose an
unacceptable risk to human health or the environment.
The lead found on site is expected to vary in size from .45 caliber bullets to small fragments.
To evaluate for the presence of lead in certain size fractions, the samples collected from the
range berm will be screened onsite using a sieve and each size fraction will be visually
observed for the presence of lead fragments. The results will be used to provide a
preliminary evaluation of whether lead can effectively be separated from site soils.
The three soil samples with the highest lead concentrations will be analyzed using the
toxicity characteristic leaching procedure (TCLP) to characterize leachate concentrations.
These data will be compared to State of Oregon cleanup criteria and federal waste
classification concentration levels.
Sample Collection and Analysis
Soil samples will be collected from the range berm, shooting lanes, areas separating the
shooting lanes (separation lane), and the open area north of the asphalt shooting lanes. The
sample locations are shown on Figure 4.
The sampling plan assumes that a given shooting lane and adjacent separation lanes will
have a similar lead distribution as the remaining lanes on site. Each area will be sampled as
described below.
Range Berm
Soil samples will be collected from the range berm as follows:
· Samples will be collected across the cross section of the range berm at the target
elevation at the range berm surface and every 2 feet horizontally towards the center of
the berm to a maximum distance of 10 feet as shown in Figure 4. The target elevation
will be considered to be 2 feet below the target cable located in front of the range berm.
· Samples will be collected from the range berm along the center line of asphalt shooting
lanes and half the distance between the centerline of adjacent shooting lanes as shown in
Figure 4.
· A backhoe will be used to access sample locations in the interior of the range berm. Soil
samples will be collected directly .from the bucket of the backhoe.

An additional volume of soil will be collected from the surface, 2-foot, and 4-foot
distances into the range berm with a shovel from the backhoe, placed on a clean piece of
plastic' tarp, mixed, and quartered (ASTM D 75). The samples will then be sieved in the
field into the following size fractions: < ~/i inch (fines), ½ to 3,4 inch, 3,~ to 1 inch, and 1 to
2 inch. Each size fraction will then be visually observed for the presence of lead
fragments. The largest fraction with no observable lead fragments (a field judgment to
be made by the sampler) will be placed in an appropriate sampling container and
submitted for lead analysis.
Asphalt Shooting Lane and Separating Lane
Soil samples will be collected from beneath the asphalt shooting lane and adjacent
separating lane as follows:
· Samples will be collected at the foot of the range berm and every 25 feet along the
shooting lane and adjacent separation lane as shown in Figure 4. Samples will be
collected from the centerline of each respective lane.
· Samples will be collected at each sample station from the following depth intervals:
to 3-inches below ground surface (bgs), 9 to 12-inches bgs, and 21 to 24-inches bgs.
· Samples can be collected from either a hand auger or from the bucket of a backhoe.
Area North
Soil samples
of Asphalt Shooting Lanes
will be collected from area north of the asphalt shooting lanes as follows:
· Samples will be collected every 25 feet along the area north of the asphalt shooting lanes
up to the clearing/tree line as shown in Figure 4. The samples will be collected along
the projected centerline of the sampled shooting lane.
· Samples will be collected at each sample station from the following depth intervals: 0
to 3-inches below ground surface (bgs), 9 to 12-inches bgs, and 21 to 24-inches bgs.
· Samples can be collected from either a hand auger or from the bucket of a backhoe.
Verification Samples
To verify the assumption that a given shooting lane and adjacent separation lane will have a
similar lead distribution as the remaining lanes on site, samples will be analyzed from four
locations in other shooting lanes or separation lanes to compare lead analysis results.
Verification samples will be collected as follows:
· Samples will be collected from four sample stations shown in Figure 4. The samples will
be collected along the projected centerline of respective shooting or separating lanes.
· Samples will be collected at each sample station from the following depth intervals: 0
to 3-inches below ground surface (bgs), 9 to 12-inches bgs, and 21 to 24-inches bgs.
· Samples can be collected from either a hand auger or from the bucket of a backhoe.
Sample Collection Procedures
Samples will be collected with disposable stainless steel spoons, placed into laboratory
supplied 8-ounce jars, and the lids secured. Surface soil samples will be collected by first
scraping away the upper 1,4 inch of material at the sample station with the handle of a spoon
and then spooning the underlying material into the appropriate sample container. Samples
at depth will be collected directly out of the hand auger or backhoe bucket with a disposable
spoon.
Documentation
Notes and observations from each sampling station and depth including sample
identification number, time of sample collection, and any additional comments will be
written in a project field notebook. Visual observations of size fractions of any lead
fragments recovered during screening will also be entered in the field notebook. Sampling
stations will be photographed. A site map will be generated in the field notebook relating
sample station identification to sample station location in the field.
Sample Handling, Storage, and Delivery
Filled sample containers will be labeled with the project name, project number, sample
number, analysis to be performed, and date and time of collection. Samples will be placed
on ice in an ice chest and packed with foam, bubble wrap, or vermiculite to prevent
container breakage. A chain-of-custody form will be completed and placed in a sealed bag
and taped to the inside lid of the ice chest. The chest will then be sealed shut with tape and
shipped or delivered to the laboratory within 24 hours of sample collection. To retain
sample custody, the samples will remain in sight of field personnel or in a locked location
until they are shipped to the laboratory.
Sample container, preservation method, and holding time requirements are listed in Table 1.
The holding time starts at the time of sample collection in the field.

Laboratory Analysis
Samples will be analyzed in a two-phased approach to obtain the most useful data while
reducing analytical costs.
Phase I Sample Analysis
Selected samples will be analyzed for total lead using EPA Method 6010. The samples to be
initially analyzed are those collected from the following locations:
· 0 to 3-inch bgs and 9 to 12-inch bgs intervals in the shooting and separation lanes at the
base of the range berm, and at 50 and 100-foot distances from the range berm
· 0 to 3-inch bgs and 9 to 12-inch bgs intervals in the area north of the shooting and
separation lanes
· 0 to 3-inch bgs and 9 to 12-inch bgs intervals from verification sample locations
· Surface, 2-foot, and 4-foot horizontal distances into the range berm
· Size fraction samples from the surface, 2-foot, and 4-foot horizontal distances into the
range berm
The laboratory will be instructed to hold the remainder of those samples analyzed for
potential future TCLP lead analysis. The one sample exhibiting the highest lead
concentration will be selected for TCLP lead analysis using extraction EPA Method 1311 or
1312.
Tables 2, 3, and 4 summarize which samples will be initially submitted to the analytical
laboratory.
Samples not selected for analysis will be held by the laboratory for potential future lead
analysis (Phase II) using EPA Method 6010.
Phase II Sample Analysis
If any of the samples collected from the 9 to 12-inch bgs interval or from the 4-foot distance
into the range berm have lead concentrations exceeding 200 milligrams per kilogram
(mg/kg) the deeper sample collected at the same sample station will be analyzed for lead
using EPA Method 6010.
Samples located distances of 25 and 75 feet from the range berm may be analyzed to further
delineate lead concentrations within 100 feet of the range berm if necessary. For example,
the 75-foot samples md~y be analyzed in the event that samples collected at the 50-foot
distance had lead concentrations exceeding 200 mg/kg and those samples at the 100-foot
distance had lead concentrations below 200 mg/kg.

Decontamination
Where possible, disposable equipment will be used. Nondisposable equipment (shovels,
sieves, hand augers, etc.) will be decontaminated prior to sampling at each location and
after sampling has been completed. The following decontamination procedure will be used:
1. Wash with tap water and Alconortx detergent solution
2. Rinse with potable water
3. Rinse with de-ionized water
Decontamination water will be allowed to run onto the ground and will not require special
handling. If a backhoe is used to obtain soil samples, the bucket will be decontaminated at
the end of the day (it will not be necessary to decontaminate between sample locations).
