What is Fenceline Monitoring?
• Action Level – 9.0 ug/m3 rolling
annual average (2.8 ppb)
• Fugitive Benzene Monitoring at
Fenceline
• Refinery MACT 1
• All Refinery Major Sources
• No exemptions

Monitors and Locations
• # Monitors
• Radial (chart)
• Linear – Every 2000 feet
• Extra Samplers
• Where? Consider…
• Facility Configuration
• Background
• Neighbors

of Monitors
< 750 acres 30˚ 12
750-1,500 acres 20˚ 18
>1,500 acres 15˚ 24

How to Monitor?
• Passive diffusion tubes
• Set # of monitors + blanks +
duplicates
• Sampling Period = 2 weeks
• Tubes to lab, deploy
replacement tubes

How to Monitor?
• Method 325A
• VOCs from Fugitive and Area
Sources
• Method 325B
• Sampler Preparation and
Analysis

Reporting
• Collect 1 year of data
• Report Quarterly
• Due 45 days after end of Quarter
• Submit via ERT/CEDRI [40 CFR §63.655(h)(8)]

CEDRI, ERT and CDX
• Increasing # of NSPS and NESHAPs/MACT require electronic reporting, or
“E-Reporting”.
• E-Reporting is completed using U.S. EPA’s Compliance and Emissions
Data Reporting Interface (CEDRI).
• CEDRI is located on U.S. EPA’s Central Data Exchange (CDX).
• Some reports (e.g., stack test results) compiled using the
Electronic Reporting Tool (ERT) before being uploaded to
CEDRI.
• Two separate entities

Reduced Monitoring
Step Down Approach, per monitor
• Every biweekly sample < 0.9 ug/m3 for 2 years, sample monthly
• Every monthly sample < 0.9 ug/m3 for 2 years, sample quarterly
• Every quarterly sample < 0.9 ug/m3 for 2 years, sample semiannual
• Every semiannual sample < 0.9 ug/m3 for 2 years, sample annual
• Any result above 0.9 ug/m3, back to biweekly

Other Rule Considerations
• Use of Meteorological Station
• Corrective Action Plan/Root
Cause Analysis
• Site Specific Monitoring Plan
• Alternative Monitoring
3/2/2016 Page 14Refinery Benzene Fenceline Monitoring
So I have two years?
• Conduct preliminary monitoring program
• Address seasonal variability
• Develop alternative monitoring plans
• Develop corrective actions
• Financial planning
• Proactively identify compliance challenges
• Establish database and public interface
• Sample equipment availability
• Identification and contracting of laboratory(ies)
