Operation and Management Section



The Operation and Management (O&M) Section oversees the operation of Vermont's municipal, large, private and industrial Wastewater Treatment Facilities (WWTFs) through periodic on-site inspections. The section also conducts oversight of effluent data collection activities by inspection of effluent sample collection, and laboratory testing procedures. The section is involved in technical review of many aspects of wastewater treatment facility management (i.e. twenty year engineering evaluations, design review for upgrades, complaint investigations, emergency pollution permit requests, etc.)

New inspector assignments effective April 1, 2012


Operation, Management and Emergency Response Plans (also known as Sewage Spill Prevention Plans)

In 2006, the Vermont Legislature passed legislation which created new discharge permit requirements for municipal wastewater treatment facilities. That legislation (Act 154) requires all municipal wastewater treatment facilities to prepare and implement an Operation, Management and Emergency Response Plan (also known as OMER Plans or Sewage Spill Prevention Plans (SSPP)). The Act becomes effective on July 1, 2007.  The Secretary of the Agency of Natural Resources has determined that OMER Plans for the wastewater treatment facility pump stations and sewerline stream crossings must be submitted to the Department by April 1, 2008.  The OMER Plans for the collection system must be submitted by July 1, 2010, or as part of the discharage permit application for discharge permits which expire on or after July 1, 2010.  Please see the August 29, 2007 Implementation Letter link, below.

In an effort to help municipalities comply with this new requirement the Wastewater Section has teamed with the Green Mountain Water Environment Association (GMWEA) to develop guidance for preparing OMER Plans. In August 2007 the Department prepared the "Written Guidance for Preparation of Plans to Prevent Sewage Spills", identifying the critical elements that must be incorporated into the OMER Plans.  At the November 6, 2007 Green Mountain Water Environment Association meeting the Department presented a Powerpoint seminar that defined some of the terms and considerations involved in the preparation of OMER Plans, including a method for quantifying the assessment of risk from treatment component failures, a "probability-risk matrix".

This overflow situation was reported and immediately addressed by the operators.

Sewer overflows may have the potential to pose
a threat to human health or the environment.
