Facility Compliance


Facility Analyst Assignments

Wastewater Inspector facility assignments are based on county.
To see a list of inspector facility assignments please visit our contact page.


Nitrogen Optimization Plans

All wastewater facilities discharging to the Long Island Sound (LIS) are required to have Nitrogen Optimization Plans (NOPs) included in their permit.  For questions and/or assistance with NOPs contact your WW Inspector.


Reported Sewer Overflow and Release Events

Sewer overflows and release events have the potential to pose a threat to human and/or environmental health.

To view information about recent sewer overflow and release events that have been reported to the Wastewater Management Program, visit our Reported Sewer Overflow and Release webpage. The search criteria is auto-filled for the previous 30 days. To see additional (earlier) data, simply adjust the begin date. NOTE: There is no data available prior to January 1, 2007.

For more information on Reported Sewer Overflows and other Release events please visit the Notice of Untreated or Unpermitted Discharges page.

Industrial User Surveys

An Industrial User (IU) Survey is a list of sources that discharge non-domestic wastewater to a publicly owned treatment works (POTW) with information about the character and volume of pollutants discharged.  This includes commercial, industrial, and other non-residential users of the sewer system, and sources of hauled waste, other than domestic septage, discharged at the POTW’s headworks or in the collection system. This does not include users discharging only domestic wastewater, such as residential homes and users discharging wastewater from bathrooms and kitchens only.

The purpose of an IU Survey is to identify and document the users discharging non-domestic wastewater and obtain information specific to each user’s wastewater discharge characteristics. This information allows POTWs to understand the quality and volume of wastewater received from its users; enables the POTW and the Vermont Agency of Natural Resources, Department of Environmental Conservation (DEC) to evaluate how the user’s discharge could affect the WWTF and receiving water and the potential applicability of a Pretreatment Permit for that user; and supports the POTW in managing its WWTF capacity, by identifying users that require allocations for flow, biochemical oxygen demand (BOD), or other pollutants of concern (POCs) established via technically based local limits.

DEC has developed the following interim guidance to assist POTWs in conducting IU Surveys voluntarily or by specific Department directive.


Operation, Management and Emergency Response Plans

In 2006, the Vermont Legislature passed legislation which created new discharge permit requirements for municipal wastewater treatment facilities. That legislation (Act 154) became effective on July 1, 2007 and requires all municipal wastewater treatment facilities to prepare and implement an Operation, Management and Emergency Response (OMER) Plans (also known as Sewage Spill Prevention Plans), which have two principle components:

  1. treatment facility, pumps stations and stream crossing; and
  2. collection systems.

In an effort to help municipalities comply with this new requirement the Wastewater Management Program teamed with the Green Mountain Water Environment Association (GMWEA) to develop guidance for preparing OMER Plans:
