Site: ConocoPhillips Refinery

– Billings, Montana F037 Delisting Petition Laboratory: ALS Laboratory Group

– Houston, Texas Work Order: 1007142, 1007146, 1007294, 1008246 Reviewer: Steve Miller/TRC Environmental Corporation Date: September 28, 2010
Samples Reviewed and Evaluation Criteria The samples reported in ALS Work Order 1007142 were analyzed for:

• Oil & Grease by U.S. EPA Method 1664

• Select Metals by SW846 Method 6020

• Mercury by SW846 Methods 7470 and 7471A

• Semivolatile Organic Compounds (SVOCs) by SW846 Method 8270

• Volatile Organic Compounds (VOCs) by SW846 Method 8260

• Reactivity by the Methods Described in SW846 Chapter 7

• Cyanide by SW846 Method 9014

• Ignitability by SW846 Method 1030

• Moisture by U.S. EPA Method 160.3

• PH by SW846 Method 9045B

• Sulfide by Standard Method 4500 S2

‐ F

TCLP analyses were also performed for metals SVOCs and VOCs with extraction per SW846 Method 1311 ( i.e., acidic extraction fluid). TCLP extractions were also performed for samples North Q4 and South Q1 using extraction fluids with pH values of 7.0 and 10.01 as noted in the delisting guidance document. The extraction fluid with a neutral pH is described in Method 1311, Section 5.2 as reagent water and has a pH of 7.0 + 0.5 standard units. The extraction fluid with an alkaline pH is described in Standard Methods for the Examination of Water and Wastewater and has a pH of 10.01 + 0.05 standard units.
The data validation was performed using laboratory

‐ specified recovery limits as evaluation criteria.

## Holding Times and Sample Preservation Samples North Q2, North Q3, North Q4, South Q1, South Q2, South Q3, South Q32, South Q4
were collected on July 1, 2010. These samples were analyzed for sulfide by Method 4500 S2

‐ F
on July 9, 2010. The calculated time between collection and analysis is eight (8) days. The method

‐ defined holding time for this analysis is seven (7) days. Therefore, the holding time is exceeded by one day for sulfide in the listed samples. The reported concentrations of sulfide in samples North Q2, North Q3, North Q4, South Q1, South Q2, South Q3, South Q32, South Q4 may be biased slightly low due to this holding time exceedance.
Blanks Barium and lead were detected in method blanks associated with acidic TCLP analyses of all samples. No interpretation issues are indicated for barium since all detected concentrations
are more than ten (10) times the blank concentration. Reported concentrations of lead in samples North Q4 and South Q1 are less than ten (10) times the blank concentration and may include significant measurement contributions form laboratory sources of contamination.
Vanadium was detected in the method blanks associated with total metals in all samples. No interpretation issues are indicated since reported concentrations of vanadium in all samples are
more than ten (10) times the blank concentrations. Naphthalene was detected in the method blank associated with batch R94008. No data interpretation issues are indicated since reported concentrations of naphthalene in associated samples are more than ten (10) times the blank concentration.

Zinc was detected in the method blank associated with basic TCLP extracts in batch 4464. Reported concentrations of TCLP (Basic) zinc in samples South Q1 and North Q4 are less than ten (10) times the blank concentration and may include significant measurement contributions from laboratory sources of contamination.
LCS Results All criteria are met. Surrogate Recoveries All criteria are met.
MS/MSD Results Sample South Q2 was analyzed as an MS/MSD pair for all analytes. Most recoveries and RPD values are within laboratory

‐ defined control limits indicating that the sample matrix has

### Page 3 of 5 

## minimal, if any, influence on the reported concentrations of target analytes. The following exceptions were, however, noted:

• Both recoveries of total nickel, total zinc, and total naphthalene are less than control limits. Data interpretation issues are not indicated for these compounds since the concentration of each in the unspiked analysis of South Q2 is more than four (4) times the spiking concentration.

• Recoveries of Oil & Grease are reported as negative values and the RPD value is greater than control limits in MS/MSD analyses of South Q2. These results are indicative of a likely low bias for the reported concentrations of Oil & Grease in this matrix as well as increased variability.

• Recoveries of total ethylbenzene are less than laboratory

‐ derived limits. These results are indicative of a likely low bias for total ethylbenzene in this matrix.

• Recoveries of total xylenes are less than laboratory

‐ derived limits and the reported RPD value is greater than the applicable control limit. These results are indicative of

a likely low bias and excessive variability for total xylenes in this matrix.

• One recovery is within limits and one recovery is outside limits for total barium, total phenanthrene, total 1,1,1

‐ trichloroethane, total 1,2

‐ dichlorobenzene, total 1,3

‐ dichlorobenzene, total 1,4

‐ dichlorobenzene, total carbon disulfide, total chlorobenzene, total styrene, total tetrachloroethane, total toluene, and TCLP tetrachloroethane (acidic extraction). No data interpretation issues are indicated for accuracy since one recovery is within control limits.

• RPD values for total dichlorobenzenes, total chlorobenzene, total styrene, and total tetrachloroethane are indicative of excessive variability in this matrix.
Field Duplicate Results Sample South Q32 was analyzed as a field duplicate of South Q3. Calculated RPD values for detected compounds are presented in the following table:

## The calculated RPD values for highlighted rows in the table above are greater than expected (RPD > 20%). These results are indicative of excessive imprecision for the highlighted analytes. Laboratory Narrative Laboratory notes for work order 1007142 indicate that area counts for 1,4

‐ dichlorobenzene

‐ d4 and naphthalene

‐ d8 in sample North Q4 were less than method

‐ required limits in SVOC analyses. Based on internal standard assignments given in Table 5 of Method 8270C (Revision 3, December 1996), the associated target analytes include 2

‐ methylphenol, 4

‐ methylphenol, phenol, 2,4

‐ dimethylphenol, and nitrobenzene. Of these, 2,4

‐ dimethylphenol and nitrobenzene

were not detected in North Q4. Therefore, reported concentrations of 2

‐ methylphenol, 4

‐ methylphenol, and phenol in North Q4 may be biased high due to the low internal standard recoveries.
