Newburyport Mayor, in email to residents affected by the landfill, explained that complaints about hydrogen sulfide odors around 1/11/13 resulted from shutdown of the flare at the landfill to allow “installation of a new condensate tank that DEP had been requiring for some time.” In addition, she reported, new piping from the pre-treatment system to the flare was installed. According to the email, the work has been completed and the system is operational. The mayor also said, “New well heads have been installed and the next steps are the completion of two tests to evaluate gas flows to ensure integrity of the system prior to connecting the new header system. This may be affected by the weather and could be delayed.” She promised to inform residents when the tests are completed and give them test results and a schedule for connecting the new system. |
