Certified Asbestos Consultant

"Certified Asbestos Consultant"

 Ellis was recently asked to respond to an asbestos-related emergency by a major southern California university.  As the first step in a large building renovation project, an abatement contractor had been hired to remove asbestos materials.  That contractor had been given a copy of the school's campus-wide asbestos survey performed by Ellis in 2007.  But for this project and for the first time, the university chose to manage the abatement project "in-house," i.e. without bid phase assistance or input from a California-certified asbestos consultant (CAC). 

With the project already underway, Ellis was finally called in . . . but only after the contractor had improperly removed eight thousand square feet of identified asbestos flooring and wallboard without proper engineering controls or notification.  When asked why they'd done it, the contractor admitted  they had received Ellis' original asbestos survey report, but had somehow "missed" the presence of these two asbestos materials.  The AQMD automatically investigated, cited the contractor, and mandated that a CAC direct all subsequent cleanup operations.  Ellis performed this service, administered remaining abatement, and the project was completed without further incident.

"Transite" Pipe and the AQMD


The proper name for it is "Asbestos-Cement", or simply "A-C" pipe, but it is also commonly called by its manufacturer JM's brand name - "Transite" pipe.

A-C pipe is present under most commercial and industrial sites.  Typically buried at a depth of 2 to 7 feet, A-C pipe was installed and used for a number of purposes:

  1. Electrical and Telephone Conduit.  Typically 2"-6" O.D. (outer diameter), A-C conduit lines can typically be found embedded in large blocks of concrete, which can make excavation and disposal challenging.
  2. High Pressure Fresh Water Line.  Sizes will range from 12" O.D. (main lines) to 4" O.D. (service lines).  Tees and elbows are often embedded in concrete thrust blocks.
  3. Sewer Lines.  A-C pipe is a common way to move sewage from homes to the wastewater treatment plant, via 4" service lines connecting to a main line of 24" or more.

In southern California, the South Coast Air Quality Management District (AQMD) now requires that ALL A-C pipes must be excavated and removed in accordance with an approved "Procedure 5" (or simply "P5") application.  The P5 must be prepared by a California certified asbestos consultant (CAC) and must accurately describe a plan to excavate, expose, remove, wrap and dispose of A-C pipe wherever it is found.  Typically, this process will require approximately 3 weeks to complete, including the 2-week notification period to the AQMD.
