in the FLIR Age
BWON Background
• Benzene Waste Operations NESHAP – effective date January 7, 1993
• BWON applies to owners / operators of chemical manufacturing plants,
coke-by-product recovery plants and petroleum refineries
• Refineries are subject to the rule if 40 CFR Part 61, Subpart FF, if they
generate greater than 10 Mg of benzene as waste and affected facilities
must comply with either the 6 BQ or 2 Mg options
• Recent enforcement and approaches provide some concepts to
sustainably upgrade BWON compliance programs

Waste Management Unit Standards
• Waste management units must be controlled for emissions unless allowable exemption is used
(e.g., they are included in the 6 BQ option)
• Periodic inspections are required for all waste management units
• Waste management unit categories
• Tanks
• Containers
• IDS
• Oil – water separators
• Treatment processes
• Closed vent systems and control devices

BWON Inspection Requirements
• New WMU’s are required to inspected initially (within 180 days)
• Quarterly visual and M21 annually
• NDE is defined as < 500 ppm
• Storage tanks – 45 days; surface impoundments, containers, IDS,
separators – 15 days for first attempt at repair
• Closed vent system – first attempt w/5 days and final attempt w/15 days
• BWON – Delay of repair (DOR) provision
• BWON – Does not allow components to be classified as DTM / UTM

Recent EPA Actions
• EPA has started to use “next
generation” approaches during
petroleum refinery BWON
inspections
• EPA’s focus on field inspections
of refinery BWON “waste
management units”
• EPA is using an infrared camera
to locate potential VOC leaks
from waste management units
and wastewater treatment
facilities, followed by FID M21
measurements to verify leaks

What is EPA finding?
• IR cameras are finding leaks,
ultimately confirmed to be greater
than 500 ppmv, on covers and
hatches associated with lift
stations, oil/water separators,
and tanks
• Camera observations also finding
leaks from bleeder vents on
regulated tanks, and seam weld
leaks on covers on wastewater
treatment process units,
equipment not regularly reviewed

Potential Regulatory Ramifications
• Failure to design and operate an IDS with no
detectable emissions
• Failure to design and operate tank roof covers
and all openings with no detectable emissions
• Failure to design and operate oil-water
separator with no detectable emissions
• Failure to seal all openings in the wastewater
treatment system
• Failure to maintain gaskets on bleeder vents
• Failure to monitor seams on DNF covers
AND
• Failure to meet 6 Mg or 2 Mg options

Storage Tank Monitoring Alternative
• Refinery obtained Alternative
Monitoring approval for BWON
tank seal inspections
• Slop oil storage tank controlled
with external floating roof
• Camera inspections in lieu of
on-the deck seal gap
inspections, repairs required if
emissions noted with camera

What Should You Consider?
• EPA will use FLIR technology during
inspections
• EPA may consider one violation to be
two – failure to control waste
management units and exceeding the
applicable benzene limit
• Will EPA use FLIR technology for
enforcement on other regulations
(e.g., NSPS Subpart QQQ)?

Best Practices
• Rule specifies annual NDE inspections;
facilities should consider conducting NDE
inspections more frequently
• Proactively incorporate FLIR technology
into BWON inspection program and/or
include in LDAR program
• How to handle known chronically leaking
components
• Are all components identified? Can FLIR
technology be used to find “hidden” and
“potential” leaks?
