Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Rocky Neck State Park is also closed until further notice due to a brush fire. Please note that today's forest fire danger report remains at a 'very high' or 'extreme' level.

Effluent Violations

You must maintain effluent quality within the limits specified in your permit. Since there are many factors that can contribute to an effluent violation, you must always:

  • Properly operate and maintain the wastewater treatment system;
  • Have capable and trained personnel operate and monitor the treatment system;
  • Treat only wastewater authorized for treatment and/or discharge by the permit.

Complying with these minimum standards should allow you to avoid or control the majority of circumstances that could lead to an effluent violation or Notice of Violation.

Learn more about notification requirements.

Improper Sample Collection, Preservation, Handling, and/or Analytical Techniques

You should review your permit requirements and pertinent regulations (especially 40 CFR Part 136) and the example DMR Sample Data Form of the DMR Instruction Manual.

Sample location; collection method; sample volume, containers, preservatives, holding time; chain of custody; and analytical methods must be appropriate to ensure valid monitoring results.
