Initial Demonstration of Capabilities (IDC) & Certification of Operator Competency (COC) Training


As set forth by the Department of Environmental Quality on September 12, 2007, Initial Demonstration of Capabilities (IDC) or Certification of Operator Competency (COC) must be successfully completed by all wastewater treatment facility analysts/operators.  The following criteria are required for an analyst/operator to successfully complete the IDC or COC:


  • The procedure must be documented, done only once per analyst per method, redone if there is a change in the analyst/operator or method.
  • The analyst/operator must analyze 4 replicates of an independent check sample of a known concentration.
  • The analyst/operator must recover 90%-110% for each replicate (SM 18th or 19th Ed.) or 80%-120% for each replicate (SM 20th or 21st Ed.)


The Department of Environmental Quality requires that an IDC or COC be performed on total residual chlorine and pH.

Fats, Oils and Grease (FOG) Compliance Training


Fats, oils and greases (FOG) are a significant concern for municipal operations of wastewater collection systems and wastewater treatment plants.  When not disposed of properly, FOG components congeal and accumulate along the walls of the sanitary sewers.

Problems include:

  • Pipe construction
  • Impeded flow of wastewater
  • Increased potential for sewer blockage
  • Pump station operations are impaired
  • Sewage accumulates in wet wells

Any of these situations can eventually result in a sanitary sewer overflow in which wastewater enters homes and businesses.

This is both an environmental issue and a public health concern, in which sewage can contaminate the ground, local bodies of water, and any property with which the wastewater comes into contact.

ESS can assist with FOG problems by:

  • Training and Best Management Practices
  • FOG Waste Discharge Permit Application
  • Sample collection and analysis
  • Assistance with Regulatory Compliance

FOG training is also offered in Spanish.
