Leak Detection and Repair (LDAR) Management

Our team of engineers and technicians can help determine regulatory and process stream applicability, audit your facility’s LDAR program with a field assessment, conduct a database review, identify and monitor leaks using EPA Method 21, and provide program training. In addition, we will review Process Flow Diagrams (PFD’s) and/or Piping and Instrument Diagrams (P&ID’s) to ensure applicable equipment is properly identified.
