In the summer of 2004, the Wastewater Treatment Facility received complaints from neighbors with residences located adjacent to the facility. Complaints referred to noise emissions from the plant. In response to those complaints the Edgartown Wastewater Commission has authorized a brief study to conduct spot measurements of octave band and dBA sound pressure levels. The measured levels are to be compared to the sound pressure levels that were acquired in the fall of year 2000, prior to when the stack silencer was installed. The study further includes a comparison of the spot check measured levels to the noise criteria defined by the Massachusetts Office of Environmental Affairs, Division of Air Quality Control (DAQC), policy 90-001, dated 1 February 1990. That comparison determines if the Wastewater Treatment Facility is in compliance with noise regulations imposed by the State of Massachusetts.

NITROGEN LOADINGS TO THE EDGARTOWN GREAT POND
The Town of Edgartown, including the Commission, has taken significant steps aimed at protecting and improving the health of Edgartown Great Pond.  In particular, the Town, including the Commission, has sought to identify and implement appropriate ways to reduce and mitigate the impacts of new and ongoing nitrogen loadings to the Pond from various nitrogen sources within the Pond watershed.  Based on these ongoing efforts, and for the purposes of fulfilling the requirements of Special Condition I(A)(g) of the Permit, the Commission makes a series of recommendations summarized in this report.

SUMMARIZES PROBLEMS & OFFERS ALTERNATIVES
The Great Pond is a coastal salt pond with occasional salt water inflow which has a number of indicators that should cause us to take extreme care in the future to limit the nutrients that the pond receives to what it is capable of processing. This includes findings and conclusions including a short term as well as long term strategies.

ODOR CONTROL ALTERNATIVES
Based on a site visit and review of data from the Edgartown WWTF the following areas have been investigated to reduce odor emissions and improve WWTF performance.  Septage Receiving and Pretreatment Area;  Dewatering Room Sludge Container Pole Barn;  Scum Handling and Disposal System.
 Alternatives investigated include structural modifications, equipment modifications, operational procedures, and chemical addition.  Each alternative is reviewed in terms of estimated costs, expected performance, operational issues, and impact on other WWTF unit processes. 

TREATMENT PLANT
The Town has a 0.755-mgd advanced wastewater treatment facility (WWTF), which included a new operations building, renovations to the xisting operations building, a pretreatment building, primary clarifiers, activated sludge process with separate anoxic and aerobic basins (the Modified Ludzack-Ettinger (MLE) process), secondary clarifiers, ultraviolet disinfection, rapid infiltration basins for effluent disposal into Martha's Vineyard's sole source aquifer, sludge processing facilities, and odor control collection and treatment systems.
