Presentation Topics• EPA Alternative Test Method ALT-122• Refinery Sector Proposed Amendments
March 2018• Refinery “X” Pilot Study Results
- Laboratory Comparison- Data Trends- Obstacles & Solutions
-
• Benzene Method Calculation• Field Duplicates and Field Blanks Required
- Original: 2 Field Blanks plus 1 Field Duplicate for every 10 Field Samples
- Updated: 1 Field Blank and 1 Field Duplicate for
-
Signed by EPA March 19, 2018• As a result of 3 separate petitions filed by AFPM/API (2)
& Earthjustice (1)• Addresses several sections of the RSR – Fenceline
Monitoring Specific:- ‘Known VOC’ defined in relation to additional monitors at
50m- Corrective Action clarification- Reporting Timing Requirements- Laboratory calculation/reporting of duplicates
RSR Proposed Amendments

Pilot Sampling Period: 09/19/17 - 12/26/177 Sampling Periods
Located in Northeast United States3 different laboratories for data comparison• Lab A: 14 Field Samples, 2 Field Blanks & 2 Duplicates• Lab B: 4 Field Samples• Lab C: 4 Field SamplesSame sampling media for each laboratory
Refinery “X” Pilot Study
-
Pilot Study: Refinery “X”
-
• Lab A: 126 Samples
• Lab B: 28 Samples
• Lab C: 16 Samples
170 Total Samples
Pilot Study: Lab Data
-
• Refiner analyzed results using Tukey-Kramer Method- All labs performed within acceptable level of one
another- Lab A statistically most accurate
• Average report TAT varied
Pilot Study: Lab Comparison
• Lab C closed after 4 sample periods

Pilot Study: Data Trends
-
Obstacle: Staying organized while using 3 labsSolution: Color coding
Pilot Study: Obstacles & Solutions
-
Obstacle: Error-free Field Test Data Sheet
Pilot Study: Obstacles & Solutions
-
Solution: Mobile Field Deployment & Collection
• Met Data, Time & Date Stamp collected automatically
• Information transmitted to Laboratory via ‘the cloud’
• Laboratory downloads all Field Test Data Sheet information
Limited handwriting and data entry greatly reduces time spent
and errors
