Facility Inspections


This section oversees the operation of Vermont's municipal, private and industrial wastewater treatment facilities (WWTFs) through periodic on-site inspections of facility operations, effluent data collections and laboratory testing procedures. The section is involved in technical review of many aspects of WWTF management, including twenty-year engineering evaluations, design review for upgrades, complaint investigations, emergency response plans, etc.

Facility Inspector 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.

Combined Sewer Overflow Control Rule

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:
