  • Enhanced LDAR in the chemical industry

    As a result of recent leak detection and repair (LDAR) audits and the associated issues (as described in the Winter 2009 issue of Environmental Quarterly), EPA is initiating enhanced LDAR programs as part of the most recent consent decrees.1 The enhanced LDAR programs for chemical facilities are more stringent than the enhanced LDAR previously required for the petroleum refining industry. ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

  • GPS Verification for Leak Detection and Repair (LDAR)

    Pen and paper, as well as barcode scanners with handheld computers, have been used in the past to record locations and times for each inspection, but that information can be easily falsified. Many companies face the critical problem of not being able to verify and prove that data was taken correctly and accurately by field technicians. Audits have revealed false numbers that were recorded in ...

  • You get what you pay for

    I had to call an electrician out to the house several months ago. After our initial conversation it took a couple more phone calls and a few more days before he actually showed up to do the work. Two hours and a few hundred dollars later and he was gone. The next day I had a small fire in my garage. What does this have to do with Leak Detection and Repair? Just like I did when hiring the ...

  • Function 3

    The LeakTracker handset was introduced somewhere in the mid 90's. It was a big deal since it allowed direct read of the instrument reading and saved the technician some typing. It also meant the exact, reading could be captured. It was also supposed to be "cheater proof" by forcing the technician to scan a bar coded tag in order to start the monitoring process. None of these feature by ...

  • `Shooting a Moving Target-Permitting Fugitive Volatile Organic Compound (VOC) Emissions,` presented at the 2004 AWMA annual conference

    Abstract Fugitive emissions from components at chemical processing facilities often appear as allowable emission limits in construction (New Source Review) and operating (Title V) permits issued by state permitting authorities - a subtle contradiction to the federal and state level regulations that regulate those very emissions. Both federal (New Source Performance Standards ...

  • Whistle Blower

    It is always interesting to get a call from someone at the EPA. "Hey Chris, we have a copy of a database and need some help understanding how the data is stored." It turns out that these specific callers had been auditing a plant and had requested a complete copy of the database. Their questions were very specific and it was very clear they thought someone had been falsifying data. They ...
